Intravenous bolus injection of an 80- to 120-mg/m2 dose of cisplatin followed by "rescue" with sodium thiosulfate (STS) was tried in the treatment of 7 patients with advanced tumor. STS was given continuously i.v. six hours after cisplatin injection, combined with methylprednisolone and metoclopramide as antiemetics. Four patients were evaluable, consisting of one CR, one PR and two NC. Severe nausea and emesis occurred in two patients and irreversible renal dysfunction occurred in one. The clinical use of the STS rescue regimen was discussed in conjunction with our basic investigation of "STS-rescue" in an animal model.
