Randomized Controlled Trial Multicenter Study Comparative Study Clinical Trial
Phase III double-blind comparison of dolasetron mesylate and ondansetron and an evaluation of the additive role of dexamethasone in the prevention of acute and delayed nausea and vomiting due to moderately emetogenic chemotherapy.
To compare the efficacy of dolasetron and ondansetron in controlling nausea and vomiting in the first 24 hours; to evaluate the efficacy when dexamethasone is added to either drug in the first 24 hours; and to extend these comparisons over 7 days in patients receiving moderately emetogenic chemotherapy. ⋯ At the doses used, dolasetron was significantly less effective than ondansetron at controlling nausea and vomiting in the first 24 hours in patients receiving moderately emetogenic chemotherapy, but there was no demonstrable difference between both drugs over 7 days. The addition of dexamethasone significantly improved the efficacy of both drugs in the first 24 hours and over 7 days.

Randomized Controlled Trial Clinical Trial
Phase III placebo-controlled trial of capsaicin cream in the management of surgical neuropathic pain in cancer patients.
A minority of cancer survivors develops long-term postsurgical neuropathic pain. Based on evidence that capsaicin, the pungent ingredient in hot chili peppers, might be useful for treating neuropathic pain, we developed the present clinical trial. ⋯ A topical capsaicin cream decreases postsurgical neuropathic pain and, despite some toxicities, is preferred by patients over a placebo by a three-to-one margin among those expressing a preference.

Clinical Trial
Phase II trial of 9-aminocamptothecin administered as a 72-hour continuous infusion in metastatic colorectal carcinoma.
The camptothecin derivative irinotecan has demonstrated clinical activity in metastatic colorectal carcinoma in both chemotherapy-naive and fluorouracil-refractory patients. 9-Aminocamptothecin (9-AC; NSC 603071), another camptothecin derivative, was selected for clinical development based on preclinical activity, including cures in human tumor xenografts resistant to standard anticancer agents. We report a phase II trial of 9-AC in patients with previously untreated metastatic colorectal carcinoma. ⋯ At the dose and schedule used in this trial, 9-AC lacked antitumor activity in metastatic colorectal cancer. 9-AC infusion schedules of longer duration are currently being investigated in this disease.

Multicenter Study Comparative Study Clinical Trial
Low risk of secondary leukemias after chemotherapy without mechlorethamine in childhood Hodgkin's disease. German-Austrian Pediatric Hodgkin's Disease Group.
In the last two decades, it has become evident that secondary leukemias after Hodgkin's disease (HD) are mainly caused by the treatment with alkylating agents, especially mechlorethamine. Since 1978, the German-Austrian trials for childhood HD have used combined chemoradiotherapy without mechlorethamine. ⋯ The observed risk of SHM is smaller than in other studies (adults and children) in which chemotherapy with mechlorethamine, vincristine, procarbazine, and prednisone (MOPP) was given. This difference can be attributed to the lower cumulative doses of alkylating agents, the absence of mechlorethamine in the chemotherapy, and the small number of patients who needed salvage therapy in the presented cohort. In general, differences in the incidence of SHM after HD reflect complex differences between treatment strategies.

Randomized Controlled Trial Multicenter Study Comparative Study Clinical Trial
Double-blind, multicenter, randomized trial to compare the effect of two doses of adrenocorticotropic hormone versus placebo in controlling delayed emesis after high-dose cisplatin in adult patients with cancer.
To compare, in a double-blind, placebo-controlled, randomized trial, the efficacy of two different doses of the depot formulation of adrenocorticotropic hormone (ACTH) in controlling delayed emesis after cisplatin. ⋯ ACTH reduces the incidence and severity of delayed vomiting and nausea after cisplatin. A dose of 2 mg 24 hours after cisplatin is better than one of 1 mg. Whether the activity of ACTH is mediated only by adrenal corticosteroids needs to be verified.
