Randomized Controlled Trial Comparative Study Clinical Trial
Hepatic arterial infusion of chemotherapy after resection of hepatic metastases from colorectal cancer.
Two years after undergoing resection of liver metastases from colorectal cancer, about 65 percent of patients are alive and 25 percent are free of detectable disease. We tried to improve these outcomes by treating patients with hepatic arterial infusion of floxuridine plus systemic fluorouracil after liver resection. ⋯ For patients who undergo resection of liver metastases from colorectal cancer, postoperative treatment with a combination of hepatic arterial infusion of floxuridine and intravenous fluorouracil improves the outcome at two years.

Studies have documented the underrepresentation of women and blacks in clinical trials, and their recruitment is now federally mandated. However, little is known about the level of participation of elderly patients. We determined the rates of enrollment of patients 65 years of age or older in trials of treatment for cancer. ⋯ There is substantial underrepresentation of patients 65 years of age or older in studies of treatment for cancer. The reasons should be clarified, and policies adopted to correct this underrepresentation.

Randomized Controlled Trial Multicenter Study Clinical Trial
Treatment of allergic asthma with monoclonal anti-IgE antibody. rhuMAb-E25 Study Group.
Immune responses mediated by IgE are important in the pathogenesis of allergic asthma. A recombinant humanized monoclonal antibody (rhuMAb-E25) forms complexes with free IgE and blocks its interaction with mast cells and basophils. We studied the efficacy of rhuMab-E25 as a treatment for moderate-to-severe allergic asthma. ⋯ A recombinant humanized monoclonal antibody directed against IgE has potential as a treatment for subjects with moderate or severe allergic asthma.

Strategies to control medical costs and improve the quality of care often translate into decisions affecting the range of services primary care physicians provide to patients, which patients are referred for specialty care, and the points in disease processes at which referrals are made. This study focused on physicians' assessments of changes in the scope of care provided by primary care physicians and their assessments of the appropriateness of the scope of the care that primary care physicians are expected to provide. ⋯ The finding that nearly one in four primary care physicians reported that the scope of care they were expected to provide was greater than it should be arouses concern about the potential impact of changes in the delivery of health care. The associations we found between financial and administrative aspects of managed care and physicians' concern about the scope of care they provide to their patients deserve careful consideration.
