Abstract

The treatment of abdominal cancer presents as major complication the spread of cancer cells into the abdominal cavity, that cause an increase in pelvic recurrence of primary cancers, such as peritoneal carcinomatosis (PC). The incidence of peritoneal carcinomatosis induces the need of surgery in the area, and unfortunately that causes peritoneal adhesions. These adhesions can cause infertility, pains and blockages, and increase the risk of failure in future surgeries.There are some available biomaterials for use as barrier intraperitoneally. A small variety of these products are approved by the FDA for use as a barrier intraperitoneal, but they provide no possibility of changes to control the release of drugs, especially focusing cases of peritoneal carcinomatosis.For this proposal the current project aims to research the biomaterial chitosan / PCL surgical barrier to prevent intraperitoneal adhesion. This biomaterial will be characterized by MEV, contact angle, DSC, mechanical test (tensile), in vitro tests with and without stretch and in vivo assay. The major focus is to investigate this promising structure for in the future act as a drug deliver for topical chemotherapy to treat peritoneal carcinomatosis. (AU)
