Abstract
The chemotherapeutic action of 5-fluorouracil monotherapy on HRS-Sarcoma in mice was compared with those of 5-fluorouracil nucleoside combinations (thymidine, cytidine or guanosine). The curative action of 5-fluorouracil was potentiated without increasing its toxicity, when cytidine or guanosine were applied at definite intervals before or after 5-fluorouracil.
