Paclitaxel/carboplatin/etoposide versus paclitaxel/topotecan for extensive-stage small cell lung cancer: a Minnie Pearl Cancer Research Network randomized, prospective phase II trial.

Purpose: To compare the combination of paclitaxel (Taxol; Bristol-Myers Squibb, Princeton, NJ, http://www.bms.com) and topotecan (Hycamtin; Glaxo SmithKline, Philadelphia, http://www.

Clinical, pharmacologic, and immunologic effects of 2'-deoxycoformycin.

Clinical, pharmacologic, and immunologic effects of 2'-deoxycoformycin (dCF) were evaluated in 15 patients with advanced malignancies. Toxicity was less severe with a low dose (4 mg/m2) of dCF, but this dose still resulted in suppression of cellular adenosine deaminase activity, skin test reactivity, and lymphocyte responses to mitogens. Improvement in cutaneous T cell lymphoma plaques was seen after dCF.

Phase I trial of the combination of 6-methylmercaptopurine riboside and 5-fluorouracil.

6-Methylmercaptopurine riboside (MMPR) and 5-fluorouracil (5-FU) were administered sequentially to 12 patients in a phase I clinical trial. Toxicities included mild nausea and vomiting, as well as reversible leukopenia and thrombocytopenia. Maximal accumulation of 6-methylmercaptopurine ribonucleoside 5'-monophosphate (MMPR-P), the active metabolite of MMPR, in patients' erythrocytes occurred between 2 and 6 h after the administration of MMPR and the degree of accumulation was dose-related.

Randomized comparison of tamoxifen versus diethylstilbestrol in estrogen receptor-positive or -unknown metastatic breast cancer: a Southeastern Cancer Study Group trial.

In a randomized study 115 postmenopausal women with advanced breast cancer who were estrogen receptor-unknown or -positive were treated initially with tamoxifen or diethylstilbestrol (DES). Their pretreatment characteristics showed no significant difference. The frequency of response was identical with tamoxifen and DES, showing a complete response rate of 2% versus 2% and a partial response rate of 4% versus 8%, respectively; stable disease was present in 78% versus 73% of the patients, respectively.
