Abstract
Purpose
The prognosis of gastric cancer patients with peritoneal metastasis (PM) remains dismal with standard systemic chemotherapy. Intraperitoneal (i.p.) chemotherapy with paclitaxel (PTX) has local effects on intra-abdominal cancer cells. According to this phenomenon, we have developed regimens combining single i.p. PTX administration with systemic chemotherapy. This treatment strategy is very promising; however, the effect of “conversion surgery” in patients responding to this chemotherapy is unclear. Therefore, we performed a retrospective study to evaluate the safety and efficacy of conversion surgery for gastric cancer patients with PM.
Methods
We enrolled 52 gastric cancer patients with PM who were treated with single i.p. PTX plus systemic chemotherapy between 2005 and 2015. Conversion surgery was performed where PM was eliminated by combination chemotherapy.
Results
Among 52 gastric cancer patients, the disappearance of PM was confirmed in 33 patients (63.5%). Gastrectomy with D2 lymph node dissection was performed in all these patients. Histological response of grade ≥ 1b was achieved in 13 patients (39%). Clavien–Dindo grade II postoperative complications occurred in three patients (9%). There were no treatment-related deaths. The median survival time and 1-, 3-, and 5-year overall survival rates of the 33 patients who underwent conversion surgery were 30.7 months and 78.8%, 36.3%, and 24.2%, respectively, and those of the 19 patients who did not undergo surgery were 12.5 months and 52.6%, 5.2%, and 0%, respectively.
Conclusion
Conversion surgery is safe and may prolong survival for gastric cancer patients with PM who have responded to single i.p. PTX plus systemic chemotherapy.
