โฆ Synopsis
Fourty-four evaluable patients were treated with 6-methylmercaptopurine riboside (MMPR) at a dose of 20 mg/m2/day X 5 by continuous IV infusion (days 1-5 and 5-fluorouracil (5-FU) on an escalating dose schedule of 300-1519 mg/m2/day X 5 by continuous IV infusion (days 2-6). Dose-limiting oral mucositis occurred at a 5-FU dose of 1,381 mg/m2/day; other toxicities included nausea, vomiting, diarrhea, skin rash, and occasional myelosuppression. A partial and a complete response were observed in two previously untreated patients with metastatic colon carcinoma given the highest 5-FU doses (1,381 and 1,519 mg/m2/day). Bone marrow phosphoribosyl pyrophosphate (PRPP) levels monitored after 24 h of MMPR treatment indicated increases of 7.8- and 9.2-fold those found prior to therapy.

In order to determine whether a simultaneous infusion of N-(phospho-n-acetyl)-L-aspartic acid (PALA) was able to increase the rate of antitumor response to 5-fluorouracil (5-FU), a pilot study was conducted. Of 10 evaluable patients with previously drug-untreated colorectal carcinoma, there were onl
