Purpose: To determine the accuracy and usefulness of oncologists' estimates of survival time in individual patients with advanced cancer.
Patients And Methods: Twenty-one oncologists estimated the "median survival of a group of identical patients" for each of 114 patients with advanced cancer. Accuracy was defined by the proportions of patients with an observed survival time bounded by prespecified multiples of their estimated survival time.
Purpose: Prolonged and disabling fatigue is prevalent after cancer treatment, but the early natural history of cancer-related fatigue (CRF) has not been systematically examined to document consistent presence of symptoms. Hence, relationships to cancer, surgery, and adjuvant therapy are unclear.
Patients And Methods: A prospective cohort study of women receiving adjuvant treatment for early-stage breast cancer was conducted.
Purpose: We compared oral capecitabine, administered intermittently or continuously, versus classical cyclophosphamide, methotrexate, and fluorouracil (CMF) as first-line chemotherapy for women with advanced breast cancer unsuited to more intensive regimens.
Patients And Methods: Three hundred twenty-three eligible women were randomly assigned to capecitabine administered intermittently (1,000 mg/m(2) twice daily for 14 of every 21 days; n = 107) or continuously (650 mg/m(2) twice daily for 21 of every 21 days; n = 107), or to classical CMF (oral cyclophosphamide 100 mg/m(2) days 1 to 14 with intravenous methotrexate 40 mg/m(2) and fluorouracil 600 mg/m(2) on days 1 and 8 every 28 days; n = 109). The primary end point was quality-adjusted progression-free survival (PFS); secondary end points included PFS, overall survival (OS), objective tumor response, and adverse events.
Purpose: Decision making in advanced cancer is increasingly complex. We developed a decision aid (DA) for patients with advanced colorectal cancer who are considering first-line chemotherapy and reviewing treatment options, prognostic information, and toxicities. We examined its impact on patient understanding, treatment decisions, decisional conflict, decision making, consultation satisfaction, anxiety, and quality of life by using a randomized trial design.

Methods: Forty-six women and their partners were interviewed separately, 3-34 months after completing adjuvant chemotherapy. Preferences were elicited using four sets of validated, hypothetical trade-off scenarios about the possible benefits of adjuvant chemotherapy on survival times (5 and 15 years) and survival rates (65% and 85% at 5 years).
Background: Depression, anxiety, fatigue, and impaired wellbeing are common, important, and closely related in advanced cancer. We aimed to identify the effects of an established antidepressant on these symptoms and survival in patients with advanced cancer who did not have major depression as assessed by clinicians.
Methods: Between July, 2001, and February, 2006, 189 patients with advanced cancer were randomly assigned sertraline 50 mg (n=95), or placebo (n=94), once per day.
Purpose: Many women who have had adjuvant chemotherapy for early breast cancer judge small benefits sufficient to make it worthwhile despite significant side effects and inconvenience. The rationality of these preferences has been questioned. We sought to better understand such preferences by assessing associations between preferences and psychosocial factors, and by asking women who judged negligible benefits sufficient to explain why.
