Antitumor effects of nucleoside analogs on peritoneal dissemination of MKN‐45‐P. MKN‐45‐P cells (1 × 10⁷) were inoculated into the peritoneal cavity of nude mice on day 0. Survival curves were constructed using the Kaplan–Meier method. 2′‐Deoxycytidine analogs (CNDAC, Ara‐C and gemcitabine) at a dose of 5 mg/kg were injected intraperitoneally every day from day 1 to day 21. 1‐(3‐C‐ethynyl‐β‐d‐ribo‐pentofuranosyl) cytosine was administered at a dose of 0.1 mg/kg on the same schedule. T/C, treatment group/control group.
