Purpose Oxaliplatin, fluorouracil, and leucovorin are commonly used to treat advanced and resected colorectal cancer. This analysis compares the safety and efficacy of oxaliplatin plus fluorouracil/leucovorin administered bimonthly (FOLFOX4) in patients age younger than and at least 70 years. Patients and Methods This retrospective analysis included 3,742 colorectal cancer patients (614 age ≥ 70) from four clinical trials testing FOLFOX4 in the adjuvant, first-, and second-line settings. End points included grade ≥ 3 adverse events, response rate (in advanced disease), progression or relapse-free survival, dose-intensity, and overall survival in the studies with mature survival data. Results Grade ≥ 3 hematologic toxicity (neutropenia [43% v 49%; P = .04] and thrombocytopenia [2% v 5%; P = .04]) were significantly higher in older patients. Older age was not associated with increased rates of severe neurologic adverse events, diarrhea, nausea/vomiting, infection, overall incidence of grade ≥ 3 toxicity (63% v 67%; P = .15), or 60-day mortality (1.1% v 2.3%; P = .20). The relative benefit of FOLFOX4 versus control did not differ by age for response rate, progression or recurrence free-survival (hazard ratio, 0.70 for FOLFOX4 v control for age < 70, 0.65 for age ≥ 70; P = .42), or overall survival (hazard ratio, 0.77 age < 70, 0.82 age ≥ 70; P = .79). Dose-intensity did not differ by age at cycles 1, 3, 6, or 12. Conclusion FOLFOX4 maintains its efficacy and safety ratio in selected elderly patients with colorectal cancer. Its judicious use should be considered without regard to patient age, although scant data are available among patients older than 80 years.

The practice of oncology can be a source of both great satisfaction and great stress. Although many oncologists experience burnout, depression, and dissatisfaction with work, others experience tremendous career satisfaction and achieve a high overall quality of life. Identifying professional goals, optimizing career fit, identifying and managing stressors specific to practice type, and achieving the optimal personal work–life balance can increase the likelihood of individual oncologists' achieving personal and professional satisfaction. In this article, we will explore how oncologists can accomplish these tasks and will examine several pervasive professional myths that often distort perspective. The article concludes in a conversation with four oncologists regarding what they find most meaningful about their work, how they manage career-specific stressors, and how they achieve balance between their personal and professional lives.

Background and Purpose— Women have poorer outcomes from stroke than men. Women also have risk factors that are unique, including pregnancy and hormone therapy. Hormone therapy for postmenopausal replacement increased the risk of ischemic stroke according to results of the Women’s Health Initiative clinical trials. Based on the current understanding of the mechanisms of action of estrogen, the reasons for this increased risk are uncertain. One method to better understand the reasons for this increased risk is to re-evaluate estrogen’s role in the neurovascular unit, simplistically comprised of the neurons, glia, and endothelial cells, as well as the processes of inflammation, and hemostasis/thrombosis. Besides the role of estrogen there are many gaps of knowledge about issues specific to women and stroke. Summary of Review— A multidisciplinary workshop was held in August 2005 to summarize the current evidence for estrogen and, more generally, stroke in women, and to provide recommendations for future basic, preclinical, and clinical research studies. Conclusions— These studies may ultimately change the approach to stroke prevention and treatment in women.

Purpose Previously, we reported results of Intergroup N9741, which compared standard bolus fluorouracil (FU), leucovorin, plus irinotecan (IFL) with infused FU, leucovorin, plus oxaliplatin (FOLFOX4) and irinotecan plus oxaliplatin in patients with untreated metastatic colorectal cancer. High rates of grade ≥ 3 toxicity on IFL (resulting in some deaths) led us to reduce the starting doses of both irinotecan and FU by 20% (rIFL). This article compares rIFL with FOLFOX4. Patients and Methods The primary comparison was time to progression, with secondary end points of response rate (RR), overall survival, and toxicity. Results Three hundred five patients were randomly assigned. The North Central Cancer Treatment Group Data Safety Monitoring Committee interrupted enrollment at a planned interim analysis when outcomes crossed predetermined stopping boundaries. The results were significantly superior for FOLFOX4 compared with rIFL for time to progression (9.7 v 5.5 months, respectively; P < .0001), RR (48% v 32%, respectively; P = .006), and overall survival (19.0 v 16.3 months, respectively; P = .026). Toxicity profiles were not significantly different between regimens for nausea, vomiting, diarrhea, febrile neutropenia, dehydration, or 60-day all-cause mortality. Sensory neuropathy and neutropenia were significantly more common with FOLFOX4. Approximately 75% of patients in both arms received second-line therapy; 58% of rIFL patients received oxaliplatin-based second-line therapy, and 55% of FOLFOX4 patients received irinotecan-based regimens as second-line therapy. Conclusion FOLFOX4 led to superior RR, time to progression, and overall survival compared with rIFL. The survival benefit for FOLFOX4 observed in the earlier stage of the study was preserved with equal use of either irinotecan or oxaliplatin as second-line therapy.
