Effect of low molecular weight heparin on intra-abdominal metastasis in a laparoscopic experimental study.
Article in International journal of colorectal disease, 2004. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
BACKGROUND AND
aimsMetastatization, adhesion, invasion, and growth of tumor cells involve a cascade of complex phenomena which may be affected. We investigated the effect of a low molecular weight heparin, reviparin, on intra-abdominal tumor growth and intra-abdominal metastasis in rats undergoing laparoscopy.
methodsCC531 adenocarcinoma cells (5x10(6) cells/ml) were administered intraperitoneally to 150 Wistar Albino Glaxo rats, with 15 groups of animals each. During laparoscopy 1 ml saline containing 0.0, 0.5, 2.0,; 4.0, and 10 mg reviparin/kg b.w. was introduced intraperitoneally (i.p.), daily subcutaneously (s.c.), or combined. After 21 days the animals were killed and underwent autopsy, and the tumor weight and the number of metastases on the liver surface were determined.
resultsTumor weight was significantly reduced by 4.0 and 10.0 mg/kg b.w. but not by 0.5 or 2.0 mg/kg b.w. compared to controls. Decreased metastatization was observed in all treated groups. These effects were most pronounced after the s.c. or combined i.p. and s.c. administration, whereas after a sole i.p. administration only the highest dose of 10 mg/kg b.w. induced a significant inhibition of tumor growth.
conclusionLow molecular weight heparin given s.c. or in combination of i.p. lavage and s.c. injections significantly inhibits intra-abdominal tumor growth and intraperitoneal metastasis of CC531 adenocarcinoma cells in rats undergoing laparoscopy. This may offer additional therapeutic options for patients undergoing laparoscopic and also open cancer surgery.
