Randomized Controlled Trial Comparative Study Clinical Trial
A prospective, randomised double-blind crossover study to examine the efficacy of strontium-89 in pain palliation in patients with advanced prostate cancer metastatic to bone.
The palliative efficacy of strontium-89 chloride has been evaluated in a prospective double-blind crossover study comparing it with stable strontium as placebo in 32 patients with prostate cancer metastatic to bone. Response was assessed 5 weeks after each treatment. 26 patients were evaluable. Complete pain relief was only reported following strontium-89 injection. Statistical comparison between placebo and strontium-89 showed clear evidence of a therapeutic response to strontium-89 compared with only a limited placebo effect (P less than 0.01).

Randomized Controlled Trial Clinical Trial
Tropisetron plus haloperidol to ameliorate nausea and vomiting associated with high-dose alkylating agent cancer chemotherapy.
Tropisetron is a novel antiserotoninergic drug with potent and specific activity against cancer chemotherapy-induced emesis. High-dose cyclophosphamide or high-dose melphalan are chemotherapeutic regimens associated with severe nausea and vomiting refractory to current antiemetic medications. We compared in a randomised open label study the antiemetic efficacy of tropisetron and alizapride in a first group of 32 consecutive patients treated with high-dose alkylating agent chemotherapy with or without autologous bone marrow transplantation. ⋯ This combination was more effective than tropisetron as single agent in preventing emetic episodes, as the median number of emetic episodes in the 72 h of observation was only 3, while they were 6 in the tropisetron group. The side-effects of tropisetron were mild and reversible upon discontinuation of the drug. We conclude that tropisetron is an effective antiemetic drug when employed in high-dose alkylating agent chemotherapy, and that its activity is potentiated by the association with haloperidol.
