OBJECTIVETo observe the impact of intraoperative peritoneal chemotherapy with Lobaplatin on the safety of postoperative bowel function and complications in patients with advanced colorectal cancer.

METHODSA total of 103 colorectal cancer patients undergoing surgical operations in our department between October 2013 and October 2014 were prospectively enrolled in this study and were randomly divided into peritoneal chemotherapy group(55 cases) and control group(48 cases) according to the random table. In therapy group, patients were treated with peritoneal implantation of 40 mg Lobaplatin intraoperatively and followed by intravenous chemotherapy using FOLFOX regimen with Oxaliplatin, Fluorouracil and Leucovorin. In control group, only FOLFOX regimen was fulfilled. Then the recovery time of bowel function, the incidence of adverse reactions and complications, and the pre- and post-chemotherapy routine blood tests and hepatorenal functions were compared.

RESULTSThe recovery time of bowel function in peritoneal chemotherapy group and control group was(72.1±11.8) h and(68.7±13.4) h respectively without significant difference(P>0.05). Each group had 6 cases with incisional fat liquefaction(10.9% vs. 12.5%, P>0.05). There was no serious infection in both groups. During intravenous chemotherapy, in peritoneal chemotherapy group and control group, the incidence of nausea and vomit(42 cases, 76.4% vs. 40 cases, 83.3%), constipation(38 cases, 69.1% vs. 29 cases, 60.4%), and diarrhea(4 cases, 7.3% vs. 5 cases, 10.4%) were observed and there were no significant differences(all P>0.05). It was noted that all these side effects vanished after chemotherapy or cured by symptomatic treatment. There were no significant differences between two groups in indexes of white blood cell, platelet, alanine aminotransferase, aspartate transaminase, and creatinine(all P>0.05), neither after operation nor after chemotherapy.

CONCLUSIONPeritoneal implantation of Lobaplatin as intraoperative chemotherapy for advanced colorectal cancer is safe and tolerable.
