Appendiceal Adenocarcinoids with Peritoneal Carcinomatosis Treated with Cytoreductive Surgery and Intraperitoneal Chemotherapy : a retrospective study of in vitro drug sensitivity and survival

Purpose: The purpose of this study was to present results on cytoreductive surgery (CRS) and hyperthermic intraperitoneal chemotherapy (HIPEC) of appendiceal adenocarcinoid (MC) with peritoneal carcinomatosis (PC), to assess drug sensitivity of AAC, as compared with colorectal cancer (CRC), and to report any discordant histopathology. Methods: Ten patients were treated with CRS and HIPEC. Treatment, drug sensitivity profiles, histopathology, and survival data were recorded and matched with potential prognostic indicators. Drug sensitivity was assessed with short-term fluorometric microculture cytotoxicity assay and compared with peritoneal metastases from CRC. Results: Patients with completeness of cytoreduction score (CC) 1 (16.4 months). In the CC 1 group. For standard drugs, tumor cells from MC and CRC were equally sensitive; except for docetaxel, to which MC was more sensitive than CRC. Conclusion: The CC-score correlated with overall survival. Candidates for this type of treatment should be referred early for evaluation in order to reach a better CC score. Drugs used for CRC also seem adequate for treatment of MC, although other drugs, eg, docetaxel, might be more active.
