Background The aim of this study was to examine the safety, pharmacokinetics, and cytological efficacy against free intraperitoneal cancer cells of intraperitoneal chemotherapy (IPC) with paclitaxel after gastrectomy with en-bloc D2 lymph node dissection (GD2) in cases of gastric cancer with peritoneal carcinomatosis (PC) and/or positive cytological findings in peritoneal washings (CFPW). Methods: Twenty-one patients with gastric cancer with PC and/or positive CFPW who underwent GD2 were treated with early, post-operative, intraperitoneal paclitaxel. Intra-chemotherapeutic toxicity and operative complication were measured using the common toxicity criteria of the National Cancer Institute, version 3.0. Intraperitoneal and plasma paclitaxel concentrations were measured using a high-performance liquid chromatography assay. Results: Grade 3 anemia occurred in two patients (9.5%) and neutropenia was observed in three patients (14.3%). No grade 4 toxicity was observed. A grade 2 operative complication was a superficial surgical site infection (4.8%) that was treated with antibiotics. Cytologically, no viable cancer cells were observed in the intra-abdominal fluid 24 hr after intraperitoneal administration of paclitaxel. The intraperitoneal/plasma area under the drug concentration-time curve (AUC) ratio was 596.9:1. Conclusion: IPC with paclitaxel after GD2 is a safe and cytologically effective treatment modality for free intraperitoneal cancer cells. However, additional data are required to determine the effect on survival. J. Surg. Oncol. 2012;105:43-47. (C) 2011 Wiley Periodicals, Inc.
