The transcoelomic spread of cancer cells gives rise to peritoneal carcinomatosis(PC) which, without special treatments, is a fatal manifestation of EOC. In order to control PC cytoreductive surgery to remove macroscopic disease is combined with perioperative intraperitoneal(IP) and perioperative intravenous chemotherapy to eradicate microscopic residual disease. Chemotherapy agents are selected to be administered by the IP or intravenous route based on their pharmacologic properties. A peritoneal-plasma barrier which retards the clearance of high molecular weight chemotherapy from the peritoneal cavity results in a large exposure of small cancer nodules on abdominal and pelvic surfaces. Tissue penetration is facilitated by moderate hyperthermia(41-42 ℃) of the IP chemotherapy solution. Timing of the chemotherapy as a planned part of the surgical procedure to maximize expo-sure of all peritoneal surfaces is crucial to success.展开更多

Methods: The patients had a performance status ofⅡ -Ⅳ on the FIGO scale.38 patients were randomized into CWIP group (16 patients) and RIP group(22 patients). CDDP was used as intraperitoneal chemotherapy (IP) with 70mg/m2. In 72h, thesamples from serum, ascites and urine were collected respectively and their platinum density weredetermined with electrochemistry polarographic analysis. On the third day and one month after IP,liver and kidney function and blood routine were examined. Results: The maximum concentration(Cmax) of plasma in CWIP and RIP groups were 3.84μg/ml and 1.27μg/ml respectively;the Cmaxof ascites were 7.04μg/ml and 4.43μg/ml respectively in the two groups. The area under the plas-ma concentration-time curve(AUC) in CWIP and RIP groups were 1067.77μg. h/ml and 191.72μg.h/ml respectively,and 1299.02μg. h/ml and 584.43μg. h/ml in ascites,their statistics dif-ference were significant ( P < 0.05). Conclusion: CWIP is better than the RIP in the pharmacoki-netics, while its side-effects is not increased. The new methods may be used on the patients.展开更多

Advanced age is risk factor for decreased survival. Optimal surgery and the safe and effective administration of chemotherapy are essential for prolonged progression-free and overall survival(OS). In this article, the available regimens in both the primary treatment and relapsed setting are reviewed.展开更多
