Intraperitoneal versus intravenous CPT-11 given intra- and postoperatively for peritoneal carcinomatosis in a rat model.
Article in Surgery today, 2006. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 papers.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
purposePeritoneal recurrence after resection of colorectal carcinoma is still a major concern. We investigated whether the novel cytostatic drug, CPT-11 (Irinotecan), delivered intraperitoneally (i.p.) and intravenously (i.v.), could inhibit intraperitoneal tumor spread in a rat model.
methodsWe induced intraperitoneal tumor growth using a tumor cell transfer model (10(6) cells) and divided the rats into the following five groups of eight: group IP1, given CPT-11 i.p. immediately after intraperitoneal tumor cell transfer; group IV1, given CPT-11 i.v. immediately after intraperitoneal tumor cell transfer; group IP2, given CPT-11 i.p. on postoperative days (PODs) 5, 10, and 15; group IV2, given CPT-11 on PODs 5, 10, and 15; and a control group. The rats were killed 30 days after tumor cell transfer, and the tumor weight, number of nodes in the greater omentum and peritoneum, presence of metastases in the liver and lungs, and ascites volume were determined.
resultsCPT-11 inhibited peritoneal tumor growth significantly. The direct intraoperative intraperitoneal application induced a more pronounced effect than the early postoperative intraperitoneal application, but both these application modes were superior to the intravenous route, which had no significant effect.
conclusionCPT-11 was highly efficacious against peritoneal carcinomatosis in this experimental model. The combination of CPT-11 with other cytostatic agents and drugs generating different effector mechanisms may diminish or even prevent intraperitoneal tumor growth.
