PURPOSE: To determine the frequency with which health-related quality-of-life (HRQL) considerations lead to modification or discontinuation of palliative chemotherapy, and the association between physicians' ratings of patients' HRQL and such treatment decisions. METHODS: Four consecutive medical consultations of 203 patients receiving outpatient palliative chemotherapy were tape-recorded and the content was analyzed to determine the frequency of and reasons for treatment alterations. Physicians rated their patients' HRQL by using the COOP/WONCA health assessment charts. Data on tumor response and treatment toxicity were obtained from the audiotapes and, when necessary, were confirmed by medical chart audits. RESULTS: Treatment was modified in 54 cases (26%) and discontinued in 40 (20%). The primary reasons for modifying treatment were toxicity (n = 22), HRQL considerations (n = 18), and tumor progression (n = 14). The primary reasons for discontinuation of treatment were tumor progression (n = 23), HRQL considerations (n = 6), and toxicity (n = 3). For eight patients, a combination of tumor progression and HRQL issues resulted in discontinuation of treatment. Treatment decisions were associated significantly with physicians' global ratings of patients' HRQL but not with more specific HRQL domains. In the presence of tumor progression or serious toxicity, HRQL considerations played little or no role in treatment decisions. Furthermore, approximately 70% of patients without evidence of tumor progression or toxicity, but with seriously impaired HRQL, continued to receive their treatment as planned. CONCLUSION: Contrary to previous findings based on physicians' self-report data, HRQL considerations seem to play a relatively minor role in decisions regarding modification or discontinuation of palliative chemotherapy.

CONTEXT: Improving health-related quality of life (HRQL) is an important goal of palliative treatment, but little is known about actual patient-physician communication regarding HRQL topics during palliative treatment. OBJECTIVES: To investigate the content of routine communication regarding 4 specific HRQL issues between oncologists and their patients and to identify patient-, physician-, and visit-specific factors significantly associated with discussion of such issues. DESIGN: Observational study conducted between June 1996 and January 1998. SETTING: Outpatient palliative chemotherapy clinic of a cancer hospital in the Netherlands. PARTICIPANTS: Ten oncologists and 240 of their patients (72% female; mean age, 55 years) who had incurable cancer and were receiving outpatient palliative chemotherapy. MAIN OUTCOME MEASURES: Patient and physician questionnaires and audiotape analysis of communication regarding daily activities, emotional functioning, pain, and fatigue during an outpatient consultation using the Roter Interaction Analysis System. RESULTS: Physicians devoted 64% of their conversation to medical/technical issues and 23% to HRQL issues. Patients' communication behavior was divided more equally between medical/technical issues (41%) and HRQL topics (48%). Of the independent variables investigated, patients' self-reported HRQL was the most powerful predictor of discussing HRQL issues. Nevertheless, in 20% to 54% of the consultations in which patients were experiencing serious HRQL problems, no time was devoted to discussion of those problems. In particular, these patients' emotional functioning and fatigue were unaddressed 54% and 48% of the time, respectively. Discussion of HRQL issues was not more frequent in consultations in which tumor response was evaluated. CONCLUSION: Despite increasing recognition of the importance of maintaining patients' HRQL as a goal of palliative treatment, the amount of patient-physician communication devoted to such issues remains limited and appears to make only a modest contribution, at least in an explicit sense, to the evaluation of treatment efficacy in daily clinical practice.

PURPOSE: This study investigated (1) the attitudes of cancer patients toward discussing health-related quality-of-life (HRQL) issues; (2) the association between such attitudes and patients' characteristics; and (3) oncologists' attitudes and self-reported behavior regarding these same issues. PATIENTS AND METHODS: Two hundred seventy-three patients receiving palliative chemotherapy and ten physicians were asked to complete a series of questionnaires. RESULTS: Almost all patients wanted to discuss their physical symptoms and physical functioning and were also willing to address their emotional functioning and daily activities. However, 25% of the patients were only willing to discuss these latter two issues at the initiative of their physician. Patients varied most in their willingness to discuss their family and social life, with 20% reporting no interest in discussing these issues at all. Female patients were more reluctant to discuss various HRQL issues than male patients. Older and less well-educated patients were more likely to prefer that their physician initiate discussion of HRQL issues. All physicians considered it to be primarily their task to discuss the physical aspects of their patients' health, whereas four physicians indicated that discussion of psychosocial issues was a task to be shared with other health care providers. All physicians indicated that they generally defer to their patients in initiating discussion of psychosocial issues. CONCLUSION: Although both patients and oncologists seem willing to discuss a wide range of HRQL issues, communication regarding psychosocial issues may be hampered by competing expectations as to who should take the lead in initiating such discussions.

This study examined the usefulness of caregiver ratings of cancer patients' quality of life (QOL), an issue of relevance to both adequate patient care and to the possible use of proxy QOL raters in clinical studies. We compared QOL ratings of 90 cancer patients receiving inpatient chemotherapy with those provided by their significant others (most often the spouse), physicians and nurses. During patients' scheduled appointment for receiving chemotherapy on a clinical ward, all raters completed independently the Dartmouth COOP Functional Health Assessment charts/WONCA, an instrument developed by a cooperative group of primary care physicians to briefly assess a core set of seven QOL domains (physical fitness, feelings, daily and social activities, overall health, pain and quality of life) by single items with five response options. With few exceptions, mean scores of the proxy raters were equivalent or similar to those of the patients. Most patient-proxy correlations varied between 0.40 and 0.60, indicating a moderate level of agreement at the individual level. Of all comparisons made, 41% were in exact agreement and 43% agreed within one response category, leaving 17% more profound patient-proxy discrepancies. Disagreement was not dependent on the type of proxy rater, or on raters' background characteristics, but was influenced by the QOL dimension under consideration and the clinical status of the patient. Better patient-proxy agreement was observed for more concrete questions (daily activities, pain) and for patients with either a very good (ECOG 0) or poor (ECOG 3) performance status. The results indicate that both significant others and health care providers can be useful sources of information about cancer patients' QOL.

The aim of this study was to examine whether significant others can provide useful proxy information on the health-related quality of life (QL) of cancer patients. We examined the level and pattern of agreement between patient and proxy ratings of the EORTC QLQ-C30, the reliability and validity of both types of information, and the influence of several factors on the extent of agreement. QL ratings were obtained for 307 and 224 patient-proxy pairs (at baseline and follow-up, respectively). Agreement was moderate to good (ICC = 0.42 to 0.79). Multitrait-multimethod analysis showed good convergence and discrimination of specific QL domains. Comparison of mean scores revealed a small but systematic bias between patient and proxy ratings. The maximum level of disagreement was found at intermediate levels of QL, with smaller discrepancies noted for patients with either a relatively poor or good QL. Both patient and proxy QL ratings were reliable and responsive to changes over time. Several characteristics of the patients and their significant others were found to be associated with the level of agreement, but explained less than 15% of the variance in patient-proxy differences. In conclusion, the present findings lend support to the viability of employing significant others as proxy respondents of cancer patients' quality of life where this is necessary.

PURPOSE: To evaluate the usefulness of caregiver ratings of cancer patients' quality of life (QL), we examined the following: (1) the comparability of responses to a brief standardized QL questionnaire provided by patients, physicians, and informal caregivers; and (2) the relative validity of these ratings. METHODS: The study sample included cancer patients receiving chemotherapy, their treating physicians, and significant others involved closely in the (informal) care of the patients. During an early phase of treatment and 3 months later, patients and caregivers completed independently the COOP/WONCA charts, covering seven QL domains. At baseline, all sources of information were available for 295 of 320 participating patients (92%). Complete follow-up data were obtained for 189 patient-caregiver triads. RESULTS: Comparison of mean scores on the COOP/WONCA charts revealed close agreement between patient and caregiver ratings. At the individual patient level, exact or global agreement was observed in the majority of cases (73% to 91%). Corrected for chance agreement, moderate intraclass correlations (ICC) were noted (0.32 to 0.72). Patient, physician, and informal caregiver COOP/WONCA scores were all responsive to changes over time in specific QL domains, but differed in their relative performance. Relative to the patients, the physicians were more efficient in detecting changes over time in physical fitness and overall health, but less so in relation to social function and pain. CONCLUSION: For studies among patient populations at risk of deteriorating self-report capabilities, physicians and informal caregivers can be useful as alternative or complementary sources of information on cancer patients' QL.

A major problem of weight reduction in obesity is the undesirable loss of lean body mass that accompanies fat loss, particularly in severe calorie restriction. In order to achieve maximal fat loss, but without great loss of lean tissue, growth hormone (GH) in a dose of 6 U/day subcutaneously was added to a very low calorie diet and an exercise program for moderately obese subjects. Body weight, body composition and hormonal status were studied during an eight-week period. The results of seven patients using GH (seven females; mean age 39.1 +/- 7.9 years; mean body weight 94.2 +/- 10.7 kg; mean body mass index 35.1 +/- 2.3 kg/m2) were compared to the results of eight patients using placebo (two males, six females; mean age 38.9 +/- 10.4 years; 100.0 +/- 11.0 kg; mean body mass index 32.9 +/- 1.9 kg/m2). The groups were comparable for demographic data. Both serum insulin-like growth factor I (IGF-I) and IGF binding protein 3 (IGFBP-3) levels became significantly higher in the GH group (p = 0.001 and p = 0.014, respectively). Mean serum IGF-I levels increased from 29.0 +/- 8.19 nmol/l at randomization to 50.14 +/- 14.66 nmol/l after 2 weeks in the GH group, whereas the levels decreased from 34.25 +/- 10.26 nmol/l to 27.63 +/- 8.14 nmol/l in the placebo group. After two weeks, IGF-I and IGFBP-3 levels stabilized. In the first half of the study serum free triiodothyronine (T3) levels remained stable in the GH group, whereas a decrease was found in the placebo group.(ABSTRACT TRUNCATED AT 250 WORDS)
