Randomized Controlled Trial Multicenter Study Clinical Trial
Establishing the dose of the oral NK1 antagonist aprepitant for the prevention of chemotherapy-induced nausea and vomiting.
The neurokinin-1 antagonist aprepitant (EMEND; Merck Research Laboratories, West Point, PA) has been shown to reduce chemotherapy-induced nausea and vomiting when it is given with a 5-hydroxytryptamine-3 receptor antagonist and dexamethasone. The current study sought to define the most appropriate dose regimen of oral aprepitant. ⋯ When it was added to a standard regimen of intravenous ondansetron and oral dexamethasone in the current study, aprepitant reduced chemotherapy-induced nausea and vomiting and was generally well tolerated, although increases in infection were noted that were assumed to be due to elevated dexamethasone levels as a result of the pharmacokinetic interaction. The aprepitant 125/80-mg regimen had the most favorable benefit:risk profile.

Multicenter Study
Conservative management of Paget disease of the breast with radiotherapy: 10- and 15-year results.
At 5-year follow-up, patients with Paget disease of the breast who were treated with breast-conserving surgery (BCS) and radiotherapy (RT) had excellent results. The current report provides 10- and 15-year rates of tumor control in the breast, as well as disease-free and overall survival rates following BCS and RT in a cohort of patients with Paget disease presenting without a palpable mass or mammographic density. ⋯ These data confirm excellent rates of local control, disease-free survival, and overall survival at 10 and 15 years following BCS and RT for Paget disease of the breast. This study continues to support the recommendation of local excision and definitive breast irradiation as an alternative to mastectomy in the treatment of patients with Paget disease presenting without a palpable mass or mammographic density.

Multicenter Study Clinical Trial
Subcutaneous interleukin-2 and interferon alpha in the treatment of patients with metastatic renal cell carcinoma-Less efficacy compared with intravenous interleukin-2 and interferon alpha. Results of a multicenter Phase II trial from the Groupe Français d'Immunothérapie.
The main objective of this trial was to evaluate the combination of subcutaneous (SC) interleukin-2 (IL-2) with interferon alpha-2a (IFN-alpha) in the treatment of patients with metastatic renal cell carcinoma (MRCC) compared with a previous trial that used continuous-infusion IL-2 and IFN-alpha with identical schedules and dosages. ⋯ The current results seem to indicate reduced efficacy and higher toxicity rates with SC IL-2 plus IFN-alpha compared with the results from a previous trial that used an identical regimen with IV IL-2 administration. Although SC IL-2 regimens are used widely, their interest remains to be determined.

Multicenter Study Clinical Trial
Interleukin-2, interferon-alpha, 5-fluorouracil, and vinblastine in the treatment of metastatic renal cell carcinoma: a prospective phase II study: the experience of Rambam and Lin Medical Centers 1996-2000.
The current study evaluated the efficacy and toxicity of interleukin-2 (IL-2), interferon-alpha (IFN-alpha), 5-fluorouracil (5-FU), and vinblastine (VBL) in the treatment of metastatic renal cell carcinoma (MRCC). ⋯ Immunochemotherapy is effective and well-tolerated by patients with MRCC. Surgical intervention for resection of residual disease is justified.

Multicenter Study
The impact of organized mammography service screening on breast carcinoma mortality in seven Swedish counties.
The evaluation of organized mammographic service screening programs is a major challenge in public health. In particular, there is a need to evaluate the effect of the screening program on the mortality of breast carcinoma, uncontaminated in the screening epoch by mortality from 1) cases diagnosed in the prescreening period and 2) cases diagnosed among unscreened women (i.e., nonattenders) after the initiation of organized screening. ⋯ Organized service screening in 7 Swedish counties, covering approximately 33% of the population of Sweden, resulted in a 40-45% reduction in breast carcinoma mortality among women actually screened. The policy of offering screening is associated with a mortality reduction in breast carcinoma of 30% in the invited population, exposed and unexposed combined. The results of the current study indicate that the majority of the breast carcinoma mortality reduction is indeed due to the screening.
