title: A phase II study of intravenous 6-thioguanine (NSC-752) in advanced colorectal carcinoma.
abstract: Fifteen patients with advanced measurable colorectal carcinoma were treated with intravenous 6-thioguanine (6-TG) at a dosage of 55 mg/m2 for 5 consecutive days every 5 weeks. Only one patient had received prior adjuvant chemotherapy. No responses were detected, and eight patients had stable disease for a medium duration of three treatment cycles. Toxicity was tolerable. We conclude that 6-TG given by this dosage schedule is ineffective in treating metastatic colorectal carcinoma.
