BACKGROUND: Adjuvant chemotherapy after curative resection for rectal cancer is the standard of care in several American and European guidelines. OBJECTIVE: The aim of this study was to examine the differences in health-related quality of life over time between patients with rectal cancer who were treated with adjuvant chemotherapy or observation. DESIGN: This is a randomized controlled phase III trial. SETTINGS: Health-related quality-of-life assessments were conducted in Dutch patients from 43 institutes. PATIENTS: Patients with stage II or III rectal cancer who underwent preoperative (chemo)radiotherapy followed by curative surgery (the SCRIPT trial) were included. INTERVENTIONS: Patients were randomly assigned to adjuvant capecitabine monotherapy for 8 cycles or observation. Health-related quality of life was assessed using the European Organization for Research and Treatment of Cancer C30 and CR38 questionnaires at 1 month after surgery (before the start of chemotherapy), and 3, 6, and 12 months after surgery. MAIN OUTCOME MEASURES: The primary outcome measure was the difference in quality of life at 6 months after surgery, just after completion of adjuvant chemotherapy for patients in the treatment group. Second, the difference in health-related quality of life at 12 months after surgery was examined. A statistically significant difference of 5 points was considered clinically relevant. RESULTS: Health-related quality-of-life results of 226 of 233 patients were available. At T3, overall quality of life (C30 summary score) was worse for patients treated with chemotherapy compared with observation (mean 82.3 versus 86.9, p = 0.006), but the difference was not clinically relevant. Patients treated with adjuvant chemotherapy reported clinically relevant worse physical functioning (mean 78.3 versus 87.0, p < 0.001) and more reports of fatigue and dyspnea (35.7 versus 21.0 and 17.1 versus 6.7, p < 0.001). All differences were resolved at 12 months postsurgery. LIMITATIONS: A selection of relatively fit patients willing to be randomly assigned may limit the generalizability of the results. CONCLUSIONS: Although inferior health-related quality of life was reported just after completion of adjuvant chemotherapy, no persistent deterioration in quality of life was detected.

Objectives: The standard treatment for hormone-receptor positive, postmenopausal early breast cancer patients is 5 years of adjuvant endocrine therapy. Previous studies demonstrate that prolonging adjuvant endocrine therapy may improve disease-free survival. However, endocrine therapy is known for its adverse events, which may negatively affect Quality of Life (QoL). The aim of this study is to assess the impact of extended adjuvant endocrine therapy on long-term QoL outcomes. Methods: 471 patients selected from the IDEAL trial were invited to complete a questionnaire 1-1.5 years after starting with extended therapy. The questionnaire consisted of the EORTC QLQ-C30 and QLQ-BR23 questionnaires. Mean QoL outcomes were compared with EORTC reference values for stage I and II breast cancer patients and the general population. Furthermore, QoL outcomes were compared between different treatment regimens. A difference of eight points was considered clinically relevant. Results: IDEAL patients receiving extended adjuvant endocrine therapy have significantly and clinically relevant better global QoL compared with reference values for stage I and II breast cancer patients (79.6 versus 64.6; p<0.01) and the general population (79.6 versus 71.2; p<0.01). Similar results were found for emotional function, pain, appetite loss, diarrhea and financial problems. Between treatment regimens prior to extended adjuvant endocrine therapy, differences were only found on specific QoL domains (e.g.arm symptoms). Conclusion: Breast cancer patients on extended adjuvant endocrine therapy have significantly and clinically relevant better global QoL compared with other stage I-II breast cancer patients and the general population, 6-8.5 years after diagnosis.@en
