The EORTC core quality of life questionnaire (QLQ-C30): validity and
reliability when analysed with patients treated with palliative radiotherapy.,
Eur J Cancer 31A: 13-14, 2260-3, Dec, 1995. |
| Abstract |
| The EORTC Core Quality of Life questionnaire (EORTC QLQ-C30)
is designed to measure cancer patients' physical, psychological and social
functions. The questionnaire is composed of multi-item scales and single
items. 247 patients completed the EORTC QLQ-C30 before palliative radiotherapy
and 181 after palliative radiotherapy. The questionnaire was well accepted
with a high completion rate in the present patient population consisting
of advanced cancer patients with short life expectancy. In addition, the
questionnaire was found to be useful to detect the effect of palliative
radiotherapy over time. The scale reliability was excellent for all scales
except the role functioning scale. Excellent criterion validity was found
for the emotional functioning scale where it was correlated with GHQ-20.
Performance of the questionnaire was improved after the second evaluation
as compared with the first. The present study shows that the EORTC QLQ-C30
is found to be practical and valid in measuring quality of life in patients
with advanced disease. |

(QLQ-C30) in patients with breast, ovarian and lung cancer., Qual Life

| Abstract |
| The QLQ-C30, a health-related quality of life questionnaire
developed for use in patients with cancer, has been previously validated
in patients with lung cancer and head and neck cancer. In this study, further
validation was carried out for 535 patients, including patients with breast
cancer (n = 143) and ovarian cancer (n = 111) for whom there is no previously
published validation, as well as patients with lung cancer (n = 160) and
a heterogeneous group of other cancers (n = 121). All patients were entered
in one of two trials of anti-emetics to prevent chemotherapy-induced emesis.
The QLQ-C30 was completed before chemotherapy and on day 8 after chemotherapy.
The factor structure in patients with breast and ovarian cancer was similar
to that previously described. Interdomain correlations, in the entire group,
were strongest for the physical and role function domains and the fatigue,
pain and global quality of life domains before and after chemotherapy.
In addition, after chemotherapy, social function was also strongly correlated
with fatigue and global quality of life. These correlations were not always
of equal strength in the breast, ovarian and lung groups, suggesting that
there may be differences between these groups. The responsiveness of the
QLQ-C30 in the presence of widely metastatic, as compared with locoregional,
disease showed changes in the expected directions (i.e., diminished function
in physical and social role functions and in global quality of life, with
greater fatigue and pain in patients with metastatic disease). Eight days
after chemotherapy, decreases were seen in physical, role and social functioning
and in global quality of life, and there was greater fatigue, nausea and
vomiting compared with before chemotherapy. Patients with breast cancer
had better physical, role and social functioning and less fatigue and pain
than patients with ovarian cancer. This result is expected, since many
of the patients with breast cancer had early stage disease, whereas those
with ovarian cancer had advanced stage disease. Mean scores for patients
with lung cancer were between the other two groups, in keeping with the
mixture of early and advanced stage disease in these patients. There was
a strong correlation between ECOG performance status scores and several
domains of the QLQ-C30; these were all in the expected directions. The
results of this study confirm those in earlier studies on patients with
lung cancer, and provide new information on patients with breast and ovarian
cancer. In addition, the QLQ-C30 is responsive to the effects of chemotherapy
and of metastatic disease. |

questionnaires for cancer clinical trials: the functional living index--cancer
(FLIC) and the quality of life questionnaire core module (QLQ-C30).,
J Clin Epidemiol 49: 1, 21-9, Jan, 1996. |
| Abstract |
| Choosing a measure instrument for a study raises the question
of whether instruments designed for the same purpose produce the same results.
We investigated this question for two instruments designed to measure subjective
quality of life (QOL) in cancer clinical trials: the Functional Living
Index-Cancer (FLIC) and the Quality of Life Questionnaire Core module (QLQ-C30).
These were administered concurrently to 98 cancer patients. Four patient
groups were defined: (1) well, no chemotherapy (n = 23); (2) adjuvant chemotherapy
(n = 24); (3) stable disease, active chemotherapy (n = 24); (4) progressive
disease (n = 27). Both instruments have global, role, social, emotional,
pain, and nausea scales; QLQ-C30 also assesses physical function, cognitive
function, and fatigue, while FLIC assesses hardship. Correlation analysis
indicated convergent validity for the global, role, emotional, pain and
nausea dimensions, but not the social dimension. Both instruments indicated
that groups 1 and 2 had better QOL than group 4 in at least one dimension.
However, different dimension-specific results meant that qualitatively
different conclusions would have been drawn if either instrument had been
used singly: FLIC indicated that group 1 had better role function that
group 4 and suffered less hardship and that group 1 suffered less nausea
than group 3, while the QLQ-C30 data indicated that group 2 had better
physical function than group 4. The only consistent result was for pain:
both instruments indicated group 4 had more pain than either groups 1 or
2. Thus the choice of QOL instrument for use in a particular trial will
affect both the results and conclusions. It is important, therefore, to
consider carefully which instrument is most likely to detect important
differences relevant to the patients' lives in that setting. |

(QLQ-C30) for use in lung cancer clinical trials. EORTC Study Group on
Quality of Life., Eur J Cancer 30A: 5, 635-42, , 1994. |
| Abstract |
| The EORTC Study Group on Quality of Life has developed a
modular system for assessing the quality of life of cancer patients in
clinical trials composed of two basic elements: (1) a core quality of life
questionnaire, the EORTC QLQ-C30, covering general aspects of health-related
quality of life, and (2) additional disease- or treatment-specific questionnaire
modules. Two international field studies were carried out to evaluate the
practicality, reliability and validity of the core questionnaire, supplemented
by a 13-item lung cancer-specific questionnaire module, the EORTC QLQ-LC13.
In this paper, the results of an evaluation of the QLQ-LC13 are reported.
The lung cancer questionnaire module comprises both multi-item and single-item
measures of lung cancer-associated symptoms (i.e. coughing, haemoptysis,
dyspnoea and pain) and side-effects from conventional chemo- and radiotherapy
(i.e. hair loss, neuropathy, sore mouth and dysphagia). It was administered
to patients with non-resectable lung cancer recruited from 17 countries.
In total, 883 and 735 patients, respectively, completed the questionnaire
prior to and once during treatment. The symptom measures discriminated
clearly between patients differing in performance status. All item scores
changed significantly in the expected direction (i.e. lung cancer symptoms
decreased and treatment toxicities increased) during treatment. With one
exception (problems with a sore mouth), the change of toxicity measures
over time was related specifically to either chemo- or radiotherapy. However,
the single item on neuropathy did not measure adequately the full range
of symptoms. The hypothesised scale structure of the questionnaire was
partially supported by the data. The multi-item dyspnoea scale met the
minimal standards for reliability (Cronbach alpha coefficient > 0.70),
while the pain items did not form a scale with reliability estimates acceptable
for group comparisons. In conclusion, the results form international field
testing lend support to the EORTC QLQ-LC13 as a clinically valid and useful
tool for assessing disease- and treatment-specific symptoms in lung cancer
patients participating in clinical trials, when combined with the EORTC
core quality of life questionnaire. In a few areas, however, the questionnaire
module could benefit from further refinements. In addition, its performance
over a longer period of time still needs to be investigated. |

| Abstract |
| The incidence of cancer is expected to increase in most European
countries by at least 20-30% in the next two decades. This change in incidence,
combined with probably small changes in cure rate, will call for an increased
effort in palliative oncology. Most patients with advanced malignant diseases
have various unpleasant symptoms which are inadequately treated. In assessing
patients' symptoms and well being, health-related quality of life (HRQL)
should be the primary endpoint. Several HRQL instruments have been found
to be valid for use in cancer clinical trials. The EORTC QLQ-C30 is one
among several cancer-specific HRQL instruments. The QLQ-C30 is composed
of nine multi-item scales and six single item measures. This instrument
is developed to be used in conjunction with disease and/or specific modules.

core EORTC quality of life questionnaire., Qual Life Res 2:

| Abstract |
| A cohort study was conducted to investigate the construct
validity of the domains of the EORTC QLQ-C30 (European Organization for
the Research and Treatment of Cancer Quality of Life Questionnaire). Ninety-six
patients undergoing chemotherapy at the Kingston Regional Cancer Centre,
Kingston, Canada were given the EORTC QLQ-C30 and two out of four comparison
scales; the Sickness Impact Profile, the McGill Pain Questionnaire, the
General Health Questionnaire and the Cancer Rehabilitation Evaluation System,
to complete during their clinic visits. Using the multitrait-multimethod
matrix to examine relationships, the Spearman ranked correlation coefficients
of similar and dissimilar domains between the EORTC QLQ-C30 and the comparison
scales were compared. The EORTC QLQ-C30 domains of pain and physical and
role functioning performed well in that they converged and diverged appropriately
with the other instruments. The domain of psychological functioning had
strong associations with domains thought to be dissimilar (social interaction
and fatigue). Social interaction and financial impact diverged across dissimilar
domains. This lack of specificity may relate to question wording. The symptom
domain had strong associations with other domains across the comparison
scales. This study shows that the domains of the EORTC QLQ-C30 have substantial
construct validity in the multidimensional assessment of the quality of
life of cancer patients and identifies where further work is required.

| Abstract |
| Quality of life (QOL) is a relatively new clinical end point
that is particularly relevant to the typically palliative therapy for non-small
cell lung cancer. Patients' assessments of their QOL are shown to differ
from their physicians', emphasizing the subjective nature of QOL. A number
of relevant instruments and assessment techniques are employed. Results
from a study using the European Organization for Research and Treatment
of Cancer (EORTC) QLQ-C30 instrument before and during chemotherapy are
presented. Some parameters improved while others did not, preventing a
simple interpretation. There are arguments for compiling indexes of QOL
while retaining measures for individual parameters and a desire for the
consistent international use of an instrument such as the EORTC questionnaire.

| Abstract |
| Patients with cervical cancer were interviewed in a focus
group format to obtain their retrospective views of quality of life (QL)
in the context of cancer treatment. In addition, they were asked to evaluate
the European Organization for Research and Treatment of Cancer's QL questionnaire
(EORTC QLQ-C30) as an indicator of their QL. Ethnographic analysis of group
transcripts revealed a number of dimensions of QL that these women did
not believe were adequately addressed by the EORTC QLQ-C30. They were:
(1) perceived control over one's body, (2) a sense of normalcy in one's
life, (3) invasiveness experienced as a result of medical interventions,
and (4) the degree of predictability of disease and treatment. Patients
also indicated that QL was determined more by the meaning and value they
placed on their experience than by the occurrence of specific functional
changes, symptoms, or side effects. The results have implications for how
QL is conceptualized. An alternative model of QL assessment, based on the
patient as expert, is illustrated and described. |

| Abstract |
| When a randomized trial (NMSG 4/90) comparing treatment with
melphalan/prednisone to melphalan/ prednisone + interferon alpha-2b in
newly diagnosed multiple myeloma was initiated in 1990, a quality-of-life
assessment was integrated into the study. We used the questionnaire (QLQ-C30)
developed by the European Organization of Research and Treatment of Cancer
(EORTC) Study Group on Quality of Life. The QLQ-C30 incorporates five functional
scales, three symptom scales, a global health and quality-of life scale
and some single symptom measures. The questionnaire was completed prior
to treatment and after 1, 6, 12, 24, 36 and 48 months. 524 (90.2%) of 581
patients enrolled in the NMSG 4/90 completed the first questionnaire, and
484 (83.3%) completed all questionnaires given to them. All but one of
the scales met the minimum criteria of reliability (Cronbach's alpha >/
0.70). Validity was shown by (1) the ability of the scales to discriminate
clearly between patients differing in clinical status as defined by pretreatment
W.H.O. performance index and Durie & Salmon stage, and (2) the sensitivity
to changes in objective disease status (response and relapse). This is
the first report of the measurement of health-related quality of life in
a prospective clinical trial in multiple myeloma. The results demonstrate
that the QLQ-C30 is a reliable and valid instrument for the measurement
of quality of life in these patients. The data will be used for a cost-utility
analysis of the results of the NMSG 4/90 trial. |

a cross-validation with the EORTC-C30., Qual Life Res 3: 6,

| Abstract |
| A cross-validation of the Karnofsky Performance Status (KPS)
and quality of life (QOL) as measured by item 30 of the quality of life
questionnaire developed by the European Organization for Research and Treatment
of Cancer Study Group (EORTC QLQ-C30) was conducted using ordered logit
analysis and prospective data from a continuous sample of 139 lung cancer
patients. The QOL is found to be a much broader concept than the KPS, since
it likely captures not only physical functioning but also functioning in
the non-physical dimensions of social, emotional, and possibly cognitive
well-being as well as the level of distress in the physical dimensions
of pain, breathing and fatigue. These results suggest that the palliative
treatment of advanced cancer and the terminally ill should be guided by
a broad concept of well-being that goes beyond one based only on physical
functioning. |

in assessment of quality of life in patients with oesophageal cancer.,

| Abstract |
| Quality of life (QOL) assessment may improve the evaluation
of treatment for oesophageal cancer but patient compliance using self completion
questionnaires is often poor. The use of a proxy to estimate QOL might
improve data collection from patients who are either unable or unwilling
to complete the questionnaire. This study examined whether a doctor or
patients' carers could accurately assess QOL using the QLQ-C30 questionnaire
developed by the European Organisation for Research and Treatment of Cancer
Study Group on Quality of Life. One doctor, 52 patients and 39 carers completed
the instrument independently. Proxy and patient ratings were analysed for
agreement using weighted kappa scores. Agreement was poor or moderate in
most QOL scales and items (kappa < or = 60). This study demonstrates
that a carer or doctor is not sufficiently accurate to postulate the patient's
responses to the questionnaire. Quality of life data, therefore, should
come from the patients themselves. |

| Abstract |
| A head and neck cancer specific questionnaire module designed
to be used in quality of life assessments before, during, and after radiotherapy
and surgery, with or without combinations with chemotherapy has been developed
in accordance with guidelines given by the EORTC Quality of Life Study
Group. Relevant issues were generated by means of literature search, and
interviews with specialists and patients. Pre-testing of a preliminary
questionnaire module was performed in patients from Norway, Sweden, Denmark,
United Kingdom and French-speaking Belgium. The resulting head and neck
cancer module, the EORTC QLQ-H&N37, includes 37 items concerning disease
and treatment related symptoms, social function and sexuality. By using
a combination of the general EORTC QLQ-C30 and the EORTC QLQ-H&N37,
health-related quality of life measurements may be compared between studies
in different cancer populations, and still be sensitive to changes in the
target population. |

| Abstract |
| Quality of life (QOL) measurement may aid decision making
in the treatment of patients with oesophageal cancer but must be clinically
valid to be useful. This study considered if the European Organisation
for Research and Treatment of Cancer QOL questionnaire, the QLQ-C30, showed
differing results in two clinically distinct groups of patients with oesophageal
cancer and also investigated the correlation between dysphagia grade and
various scales of QOL. Patients treated by oesophagectomy reported significantly
better physical, emotional, cognitive, and global health scores than those
in the palliative treatment group. Patients who received palliative treatment
had significantly worse pain, fatigue, appetite loss, constipation, and
dysphagia. The correlations between dysphagia grade and each of the QOL
scales and items in both groups of patients were poor. This questionnaire
differentiates clearly between the two clinically distinct groups of patients,
but to be an entirely appropriate indicator of QOL in patients with oesophageal
cancer, an additional specific oesophageal module including a dysphagia
scale is required. |

the European Organization for Research and Treatment of Cancer Core Quality-of-Life
Questionnaire., J Clin Oncol 13: 5, 1249-54, May, 1995. |
| Abstract |
| PURPOSE: The European Organization for Research and Treatment
of Cancer Core Quality of Life Questionnaire (EORTC QLQ-C30) is a well-validated
instrument that assesses health-related quality of life (HRQOL) in cancer
patients. It is used in cancer clinical trials in Europe, Canada, and the
United States, and has demonstrated high reliability and validity in different
groups of cancer patients. Despite thorough testing of reliability and
validity, we have not identified any reports on its test/retest reliability;
thus, a test/retest study was performed at the Norwegian Radium Hospital
(NRH). MATERIALS AND
METHODS: Cancer patients from the out-patient clinic who were off treatment
for > or = 3 months were eligible for the study. The EORTC QLQ-C30 was
given to the patients when they presented for their visit. The second questionnaire
was received by the patients 4 days later. Of 291 eligible patients, 270
(93%) agreed to participate and 190 (73%) completed both questionnaires.
RESULTS: The test/retest reliability measured by Pearson's correlation
coefficient was high for all functional scales, with a range from .82 for
cognitive and role function to .91 for physical function. The r value for
global HRQOL was .85. For the symptom scales--nausea/vomiting, fatigue,
and pain--the coefficients were .63, .83, and .86, respectively. The single-item
coefficients ranged from .72 for diarrhea to .84 for financial impact.
The Spearman rank correlation was in the same range for all dimensions.
CONCLUSION: The EORTC QLQ-C30 seems to yield high test/retest reliability
in patients with various cancer diagnoses whose condition is not expected
to change during the time of measurement.

study., Eur J Cancer B Oral Oncol 31B: 4, 235-41, Jul, 1995.

| Abstract |
| One to six years after treatment for head and neck cancer,
68 patients were asked to fill in a questionnaire at home with a subsequent
examination at the out-patient clinic of the Ullev al University Hospital.
50 patients (74%) both answered the questionnaire (the EORTC QLQ-C30, a
diagnosis specific questionnaire module, the GHQ-20, and two questions
from a population survey) and presented for examination where the clinician
rated side effects after treatment, and filled in the Karnofsky Performance
Status and the Spitzer's Quality of Life index. No patients had relapse
or second primary tumours at the time of examination but a variety of post-treatment
side effects were recorded. The patients appeared to report lower quality
of life including more post-treatment side effects compared with the clinician's
assessments. The cost-benefit of the standard clinical follow-ups in terms
of increased survival may be questioned. Patients seem to need better support
in coping with the physical and psychosocial problems which often appear.

studies of the National Cancer Institute of Canada Clinical Trials Group.,

| Abstract |
| Since 1989, the National Cancer Institute of Canada Clinical
Trials Group (NCIC CTG) has been successful in implementing and completing
health-related quality-of-life (HQL) assessments as part of phase III clinical
trials. Compliance rates for completing HQL instruments remain high, with
a minimal amount of missing data. It is believed that this success is attributable
not only to the high degree of commitment to measuring HQL by clinical
trials investigators, nurses, data managers, and central office administrative
staff, but also to the educational process that was instituted after the
development of a CTG policy for measuring HQL. From inception to May 1995,
a total of 27 clinical trials with HQL assessment have been initiated or
completed. In the majority of trials, the core HQL instrument is the European
Organization for Research and Treatment of Cancer Quality of Life Questionnaire
(EORTC QLQ-C30). In addition to answering specific questions about HQL
in these clinical trials, the trials provide the opportunity to do research
into the measurement of HQL. Thus, current clinical trials include research
questions about the appropriate timing of assessments, the reliability
and validity of the QLQ-C30 and other instruments, the role of HQL data
in assessing toxicity, and the significance of the results of HQL assessments.
It is anticipated that this activity not only will be a rich source of
information about the effects of cancer and its treatment on HQL but also
will lead to improvements in measuring HQL in oncology. |

patients 7-11 years after curative treatment., Br J Cancer 71:

| Abstract |
| Long-term survivors of head and neck cancer may suffer from
psychological distress and reduced quality of life because of late side-effects
of the treatment. In a follow-up study of patients randomised to two different
radiation fractionating regimens, 204 patients filled in a mailed questionnaire
7-11 years after treatment. The questionnaire consisted of the General
Health Questionnaire, 20-item version (GHQ-20), and the EORTC Core Quality
of Life Questionnaire (EORTC QLQ-C30). There were no differences in psychological
distress between patients receiving conventional radiotherapy and those
receiving a slightly hypofractionated regimen. A high prevalence of psychological
distress was found in both treatment groups (30% of 'cases' according to
the GHQ-20), especially in patients with impaired cognitive or social function,
or with pain. Clinicians need to be aware of this morbidity, and their
ability to detect patients with psychological problems needs to be improved.
The GHQ-20 can facilitate the communication process in a clinical setting.
With an increased awareness of these problems and by using valid instruments
for identification of patients at risk, the clinicians may intervene and
help the patients to reduce their psychological distress. |

| Abstract |
| Five acute leukaemia or highly malignant lymphoma patients
at a hospital in southern Sweden were interviewed about their daily living
problems, their coping strategies and their opinions about the nursing
care they received during the active phase of their treatment. In addition
the EORTC QLQ-C30, the Global Life Quality and the Sense of Coherence scales
were administered. The data were analysed from a hermeneutic phenomenological
perspective and interpreted to indicate that the patients sensed a threat
to their lives, loss of control, and having to live with uncertainty stemming
from the disease and the treatment. They had problems with fatigue, diarrhoea,
nausea and vomiting, loss of appetite, sore mouth and high temperature.
However, they seemed to minimize the importance of these problems and instead
focused on gaining control of the situation, developing their knowledge
of the disease and relying on the support of their family. Contradictions
appeared in their statements about the quality of care, the information
given was said to be good but difficult to understand; although the quality
of the nursing care was judged to be high it had to be asked for. That
is, help was received on request. The patients' perspective of the family
and the nurses should be studied in further research in order to fully
understand the patients' coping strategies and how nursing care can support
them. |

| Abstract |
| The generic measure, SF-36, was developed in the US. It covers
both functioning and well-being and has proved suitable for clinical outcomes
research, patient monitoring and health care planning. To protect the forms
and scoring algorithms of the SF-36 and ensure comparability across studies
and countries the copyright was placed with Medical Outcomes Trust, a non-profit
making organization. Researchers are granted permission through a user
agreement procedure. An international team of investigators is developing
authorized translations of the SF-36 through the International Quality
of Life Assessment (IQOLA) Project, sponsored by Glaxo Research Institute,
Research Triangle Park, North Carolina, USA, and Schering-Plough Corporation,
Kenilworth, New Jersey, USA. The Swedish test version is currently available
on a case-by-case basis at the Health Care Research Unit. The tumor-specific
measure, QLQ-C30, was developed and proved reliable in cross-cultural field
studies, created by the Quality of Life Study Group within the European
Organization for Research and Treatment of Cancer (EORTC). It includes
questions on functioning, symptom burden and global quality of life across
tumors, supplemented by diagnosis--or therapy-specific additional modules.
The instrument is copyrighted and all translations are placed with the

ovarian cancer: current state of research., Support Care Cancer 4:

| Abstract |
| Ovarian cancer is the most malignant cancer in women, where
it is the fifth leading cause of cancer-related death. The disease and
its treatment have considerable effects on the quality of life of patients
with this cancer. This study reviews existing literature on quality of
life in patients with ovarian cancer to demonstrate the importance of the
topic, to comment on improvements achieved and to consider their implications
for the implementation of optimal treatment. A literature search was carried
out through MEDLINE and of published papers on quality of life in patients
with ovarian cancer from 1976 to 1994. Twenty papers have been reviewed,
of which, 10 were treatment-related assessments of quality of life and
the remaining 10 dealt with different topics including psychometric issues
in measuring health-related quality of life. Twenty-four instruments were
employed to measure quality of life. Of these, the Rotterdam Symptom Checklist
(RSCL) and The European Organisation for Research and Treatment of Cancer
Core Quality of Life Questionnaire (EORTC QLQ-C30) were found to be the
most appropriate. Although meta-analysis of results is impossible, it appears
that debulking surgery followed by platinum-based chemotherapy could improve
both quality of life and survival. In addition to effective and efficient
treatment, psychological counselling, palliative and home care, nutritional
support and pain relief are the most important areas for improving quality
of life of patients with ovarian cancer. Knowledge and insight into the
quality of life of patients with ovarian cancer are still limited, and
a large carefully planned international study is required. Use of existing
standard measures is preferable and agreement should be reached on a selected
single instrument. |

for head and neck cancer: a follow-up study 7 to 11 years after radiotherapy.,

| Abstract |
| PURPOSE: To compare health-related quality of life factors
in 845 head and neck cancer patients randomized to receive either conventional
radiotherapy (2 Gy, 5 days-a-week) or a hypofractionated regimen (2.35
Gy, 4 days-a-week), a follow-up study was carried out 7 to 11 years after
treatment in the surviving patients, representing 30% of the original patient
number.
METHODS AND MATERIALS: The cancer-specific EORTC Core Quality of Life
Questionnaire (30 item version; the EORTC QLQ-C30) and a 19 item head and
neck cancer-specific questionnaire were mailed to the 245 surviving patients
of the trial. The EORTC QLQ-C30 is comprised of six multi-item function
scales, three symptom scales, and six single items which assess both symptoms
and economic consequences of the disease. Two hundred and four patients
(83%) completed the questionnaire. The two groups of patients (N = 103
and N = 101) treated by different fractionating schedules, were comparable
with regard to sociodemographic variables, tumor site, treatment variables
(including different types of surgical treatment), and secondary primary
cancers. Patients in the conventional group had more advanced disease and
a higher recurrence rate compared to patients in the hypofractionated group.
RESULTS: Unexpectedly, patients in the hypofractionated group, reported
similar or better quality of life compared to patients in the conventional
fractionated group. Patients in both groups described a high level of symptoms,
like dryness in the mouth and mucus production. Clinical and sociodemographic
variables did not explain variance in social function, emotional function
or fatigue, except for the type of surgery performed, which significantly
influenced the patients' emotional function.
CONCLUSION: Long-term survivors of head and neck cancer reported a high
level of disease and treatment related symptoms. Emotional function was
significantly influenced by the type of surgical procedure. Strategies
for future trials in head and neck cancer should continue to attempt to
stress conservative surgical approaches and coordinated adjuvant therapy
to maximize local regional control and quality of life. Functional and
emotional outcome are important parameters which should prospectively be
evaluated in future clinical trials in head and neck cancer.

| Abstract |
| Quality of life (QOL) variables are increasingly included
as end points in cancer therapy trials, supplementing such traditional
end points as survival time in evaluating the effects of cancer treatments.
Consensus has been reached that a number of QOL components (symptom status
and physical, emotional, role, and social functioning) should be measured.
Assessing multiple health-related QOL dimensions, as compared with a global
score, provides a more detailed accounting of specific effects of cancer
treatment on patient functioning. Southwest Oncology Group QOL assessment
policies emphasize patient reports and the need for systematic quality
control procedures. The Southwest Oncology Group QOL questionnaire comprises
a battery of categorical scales with established psychometric properties.
A set of generic core scales is always included in the battery, and treatment-
and disease-specific scales are developed for each trial. Other frequently
used QOL questionnaires, such as the European Organization for Research
and Treatment of Cancer QLQ-C30, the Cancer Rehabilitation Evaluation System
questionnaire, and the Functional Assessment of Cancer Therapy are alternative
instruments in current use. Quality of life findings from lung cancer clinical
trials indicate a prevalence of symptom distress, fatigue, and decline
in functional status, although patients also experience symptom management
problems without treatment. A summary of preliminary QOL findings for two
vinorelbine (Navelbine; Burroughs Wellcome Co, Research Triangle Park,
NC; Pierre Fabre Medicament, Paris, France) trials (randomized and single-arm)
in patients with non-small cell lung cancer show that symptom status was
as good or better for patients receiving vinorelbine compared with those
receiving 5-fluorouracil/leucovorin in the randomized study. Differences
in other QOL dimensions were not detected. Findings for the single-arm
trial of oral vinorelbine were generally consistent with those of the randomized
trial. |

| Abstract |
| BACKGROUND: The results of chemotherapy for patients with
esophagogastric carcinoma have generally been modest but regimens developed
more recently have produced higher response rates, and rekindled interest
in neoadjuvant chemotherapy. One such regimen is epirubicin, cisplatin,
and 5-fluorouracil (ECF). This study evaluates its efficacy, toxicity,
impact on quality of life (QL), and impact on survival in a large consecutive
series of patients with metastatic and locally advanced disease (LAD).
METHODS: Patients with histologically confirmed esophagogastric carcinoma
were treated with ECF (epirubicin 50 mg/m2 and cisplatin 60 mg/m2 every
3 weeks with continuous infusion of 5-fluorouracil (5-FU) 200 mg/m2/d).
Responses were evaluated with computed tomography (CT) scan and endoscopy.
QL was assessed using the European Organization for Research and Treatment
of Cancer QLQ-C30 questionnaire.
RESULTS: A total of 235 patients were treated, 173 with metastatic disease
and 62 with LAD. The mean number of cycles delivered was 6 (range: 1-11)
and patients were followed-up for a median of 8 months. Response was observed
in 135 of 220 (61%) evaluable patients, with a complete response (C(R)),
11% of the patients and a partial response in 50% of the patients. Patients
with moderately differentiated adenocarcinomas and LAD responded most favorably.
Symptomatic improvement was achieved in the majority of cases (63-78% depending
on the symptom). Toxicity was generally only mild to moderate, with severe
non hematologic toxicity in less than 12% of the patients and only 6 (2.5%)
treatment related deaths. QL assessment showed no significant negative
impact on emotional functioning and good symptomatic control. Surgery following
response to ECF was performed in 29 of the LAD patients, and in 19 cases
(66%) a potentially curative resection was possible, with histologic CR
in 32% of the patients.
CONCLUSIONS: ECF is a highly active regimen with acceptable toxicity
in patients with esophagogastric adenocarcinoma. In a proportion of patients
with LAD, chemotherapy enabled potentially curative surgery to be performed.
The results justify further investigation of this regimen in a neoadjuvant
setting.

| Abstract |
| PURPOSE: The aim of this study was to investigate the effects
of adding interferon alfa-2b (IFN) to protracted venous infusion fluorouracil
(PVI 5-FU) from the start of treatment in patients with advanced colorectal
cancer. PATIENTS AND
METHODS: Patients who attended our unit with histologically confirmed
advanced colorectal cancer were randomized to receive either PVI 5-FU 300
mg/m2/d via Hickman line, and IFN 5 MU subcutaneously three times weekly,
or PVI 5-FU alone. Treatment was given for a maximum of two 10-week blocks,
with a 2-week gap for reassessment of all parameters. Quality of life (QL)
was measured by the European Organization for Research and Treatment of
Cancer (EORTC) Quality of Life Questionnaire Core 30 (QLQ-C30) pretreatment
and every 6 weeks thereafter.
RESULTS: A total of 160 patients were randomized, with 155 eligible
for assessment. Radiologic response was observed in 43 patients (28%):
17 of 77 (22%) in the 5-FU-plus-IFN arm (all partial responses [PRs]) and
26 of 78 (33%) in the 5-FU-alone group (complete responses [CRs] and 22
PRs) (difference not significant). Symptomatic improvement occurred in
the majority of patients, and equally in both arms: 61% to "80%" depending
on the symptom. There was no significant difference between the two groups
in failure-free survival (median, 161 v 193 days) or overall survival (median,
328 v 357 days). However, patients who received IFN did experience significantly
more toxicity in the form of leukopenia (P = .001), neutropenia (P = .04),
mucositis (P = .008), and alopecia (P = .0002). There were no toxic deaths
and few notable differences in QL between the two arms.
CONCLUSION: This study confirms that PVI 5-FU is effective in treating
the symptoms associated with metastatic colorectal carcinoma, with only
mild to moderate toxicity and maintenance of QL. IFN 5 MU three times weekly
does not enhance these palliative benefits.

| Abstract |
| BACKGROUND: In 1986, the European Organization for Research
and Treatment of Cancer (EORTC) initiated a research program to develop
an integrated, modular approach for evaluating the quality of life of patients
participating in international clinical trials. PURPOSE: We report here
the results of an international field study of the practicality, reliability,
and validity of the EORTC QLQ-C30, the current core questionnaire. The
QLQ-C30 incorporates nine multi-item scales: five functional scales (physical,
role, cognitive, emotional, and social); three symptom scales (fatigue,
pain, and nausea and vomiting); and a global health and quality-of-life
scale. Several single-item symptom measures are also included.
METHODS: The questionnaire was administered before treatment and once
during treatment to 305 patients with nonresectable lung cancer from centers
in 13 countries. Clinical variables assessed included disease stage, weight
loss, performance status, and treatment toxicity.
RESULTS: The average time required to complete the questionnaire was
approximately 11 minutes, and most patients required no assistance. The
data supported the hypothesized scale structure of the questionnaire with
the exception of role functioning (work and household activities), which
was also the only multi-item scale that failed to meet the minimal standards
for reliability (Cronbach's alpha coefficient > or = .70) either before
or during treatment. Validity was shown by three findings. First, while
all interscale correlations were statistically significant, the correlation
was moderate, indicating that the scales were assessing distinct components
of the quality-of-life construct. Second, most of the functional and symptom
measures discriminated clearly between patients differing in clinical status
as defined by the Eastern Cooperative Oncology Group performance status
scale, weight loss, and treatment toxicity. Third, there were statistically
significant changes, in the expected direction, in physical and role functioning,
global quality of life, fatigue, and nausea and vomiting, for patients
whose performance status had improved or worsened during treatment. The
reliability and validity of the questionnaire were highly consistent across
the three language-cultural groups studied: patients from English-speaking
countries, Northern Europe, and Southern Europe.
CONCLUSIONS: These results support the EORTC QLQ-C30 as a reliable and
valid measure of the quality of life of cancer patients in multicultural
clinical research settings. Work is ongoing to examine the performance
of the questionnaire among more heterogenous patient samples and in phase
II and phase III clinical trials.

| Abstract |
| This study aimed to contribute to the validation of the 30-item
Quality of Life Questionnaire developed by the European Organization for
Research and Treatment of Cancer Study Group (EORTC QLQ-C30). The sample
consisted of 177 cancer patients with heterogeneous diagnoses. A series
of scales representing various dimensions of quality of life were tested,
including those proposed by the EORTC Study Group. Mokken's non-parametric
latent trait model for unidimensional scaling was used as the basic scaling
procedure. This model gives coefficients of scalability in addition to
reliability coefficients. In terms of scalability measured by Loevinger's
H, all EORTC Study Group scales, except the cognitive functioning scale
were found to be quite satisfactory. The cognitive functioning scale and
the role functioning scale were below the satisfactory level in terms of
reliability (internal consistency). In total, our study strengthens the
external validity of the EORTC QLQ-C30 and confirms that it may be used
on cancer patients with various diagnoses. |

| Abstract |
| The EORTC Study Group on Quality of Life (the Study Group)
has adopted a modular approach to quality of life (QOL) assessment in cancer
clinical trials. A 'core' instrument-the QLQ-C30-has been designed to cover
a range of QOL issues relevant to a broad spectrum of cancer patients.
It is intended that this QLQ-C30 be supplemented by more specific subscales
('modules') to assess aspects of QOL of particular importance to specific
subgroups of patients. Since individual members of the Study Group were
to be involved in module development, guidelines were required to standardize
the module development process in order to ensure uniformly high quality
across modules. These guidelines are presented in this paper. The term
'module' is defined, the composition of modules is outlined, and the criteria
used to develop modules are specified. The module development process,
consisting of four phases (generation of relevant QOL issues, operationalization
of the QOL issues into a set of items, pretesting the module questionnaire,
and large-scale field-testing) is described in detail. Further, issues
related to cross-cultural instrument development, and the need for monitoring
the module development process from within the Study Group are discussed.
Finally, experiences with developing two site-specific modules (i.e., for
head and neck, and breast cancer), are presented and the extent to which
the guidelines meet practical requirements is discussed. The guidelines
appear to provide a practical tool for module construction, that can facilitate
the development of a comprehensive system for assessing the QOL of cancer
patients internationally. |
