Abstract
Background: Cytoreductive surgery (CRS) followed by hyperthermic intraperitoneal chemotherapy (HIPEC) can improve the prognosis of selected patients with peritoneal surface malignancy (PSM). Usually, treatment is performed as an extensive one-step approach. We investigated the feasibility of delayed HIPEC, if the one-step procedure was interrupted precociously. Methods: 42 patients with PSM who underwent CRS and delayed HIPEC from 2006–2008 were studied. HIPEC was performed 5 days after treatment with mitomycin, cisplatin and hyperthermia. Perioperative complications and toxicity were analyzed. Results: Delayed HIPEC was successfully completed in 40 of the 42 patients. In 2 cases, HIPEC was omitted because of complications during chemotherapy (anastomotic leakage and retroperitoneal edema). Minor and major surgical complications occurred in 18 and 9 of the 40 patients treated with HIPEC (45 vs. 22.5%), respectively. Toxicity grade II–IV (WHO criteria) was observed in 4 of them (10%). Median stay in the intensive care unit was 9 days (range 2–31) while the mean hospitalization time was 24 days (range 14–59). In this series, there was no mortality. Conclusion: Postponement of HIPEC after CRS (two-step approach) is feasible. Analysis of morbidity and mortality showed no significant difference to the one-step approach reported in the literature and no disadvantages for the patient. The two-step approach is an alternative option for patients who had to discontinue the one-step approach due to unpredictable intraoperative complications.
