In the United States, hospice and palliative care are two distinct expressions of the hospice interdisciplinary team approach to end-of-life care, which originated in Great Britain in the 1960s. The hospice movement developed largely as a home-care program and alternative to conventional care. Hospice regulations and reimbursement allowances limit services to patients who are expected to die within 6 months and who forego many common oncologic treatments. ⋯ Palliative care entertains all appropriate forms of care at any phase of an illness. In this review, we describe the key goals of palliative care, which include excellent pain and symptom control, psychosocial and spiritual support for the patient and family, informed decision-making, and coordinated services across the continuum of care. We focus on selected recent developments that are important to oncology practice: the role of artificial nutrition; management of malignant small bowel obstruction; communication tasks, such as information sharing, recognition of patient preferences, advanced-care planning, and bereavement care; and ethical principles related to the hastening of death.

Fatigue is one of the most common symptoms experienced by patients with cancer and other progressive diseases. Although reported to be a major obstacle to maintaining normal daily activities and quality of life, remarkably few studies of this syndrome have been conducted. This trend is slowly changing with the recognition of fatigue as a diagnosis by the International Classification of Diseases 10th Revision-Clinical Modification; the introduction of new instruments for the measurement of fatigue; and the publication of practice guidelines. ⋯ Interventions for fatigue involve therapies targeted at the correction of the potential etiologies and symptomatic therapies that may be pharmacologic or nonpharmacologic. Possible primary therapies include modification of the patient's drug regimen, correction of metabolic abnormalities, nutritional support, and pharmacologic treatments for anemia, insomnia, or depression. Symptomatic interventions include specific drug treatment, modification of activity, exercise, and cognitive therapies.

Anastrozole (Arimidex), letrozole (Femara), and exemestane (Aromasin) are members of the third generation of aromatase inhibitors that has now replaced aminoglutethimide (Cytadren), the progestins, and tamoxifen (Nolvadex) as the hormonal therapy of choice in estrogen-receptor-positive, postmenopausal, metastatic breast cancer. This article will review the role of aromatase in the pathogenesis of breast cancer and the results of recent studies that have established the role of its inhibitors in estrogen-receptor-positive breast cancer. We will also briefly outline the rationale and design of ongoing studies.

Colorectal carcinoma is one of the most common malignancies in the western world, and although fluorouracil (5-FU) has been used in its treatment for almost 40 years, new agents with significant activity have been introduced recently. Irinotecan (CPT-11, Camptosar), a topoisomerase I inhibitor, administered at 300 to 350 mg/m2 every 3 weeks is significantly more active than continuous-infusion 5-FU in patients who have experienced disease progression after conventional therapy with 5-FU. In comparison to best supportive care, irinotecan improves survival and preserves quality of life despite treatment-related toxicity. ⋯ It has been evaluated as a single agent against advanced colorectal carcinoma in the salvage setting and also in combination with 5-FU as initial therapy for metastatic disease (where it shows significant activity). The toxicity profile of oxaliplatin (chiefly characterized by neurotoxicity) differs from that of irinotecan (primarily producing diarrhea) and the potential, therefore, exists for combining these agents or for exploiting their possible synergy with 5-FU. The introduction of these two new active agents of different pharmacologic classes promises to enable significant improvements in the treatment of patients with colorectal carcinoma.

Despite the fact that there are only a few controlled trials demonstrating the benefits associated with the use of corticosteroids in specific situations, these agents are administered frequently to patients with advanced cancer. Corticosteroids may be used alone or as adjuvants in combination with other palliative or antineoplastic treatments. ⋯ In the adjuvant setting, corticosteroids help to alleviate pain in advanced cancer patients, including specific situations such as back pain related to epidural compression. This article reviews the evidence supporting the use of corticosteroids in a broad range of situations seen in patients with advanced cancer.
