BackgroundPeritoneal carcinomatosis from colorectal origin carries a poor prognosis. Recent clinical studies show that cytoreductive surgery (CS) combined with hyperthermic intraperitoneal chemotherapy (HIPEC) improves survival of selected patients with a colorectal carcinoma and isolated peritoneal carcinomatosis in the absence of extra-abdominal metastases. Here, we report the clinical outcomes and survival after cytoreductive surgery and HIPEC of the first cohort of patients treated in our institution.MethodsSixty-seven patients underwent a laparotomy. Complete cytoreduction could be performed in 49 patients, who underwent a total of 53 CS-HIPEC procedures. All had peritoneal carcinomatosis originating from primary colorectal, cecal, appendiceal, and gastric tumors.ResultsIn patients who underwent CS-HIPEC, an R0 resection could be achieved in 4%, R1 in 88%, and R2 in 8%. The 30-day mortality was 0; one patient died in-hospital after 10 weeks. The median hospital stay was 12 days (range 4-56). The overall morbidity was 43%, including extended gastroparesis (11%), anastomotic failure (11%) and intra-abdominal abscess (9%). Mean time to clinical recurrence was 12 months (range 4-22). The actuarial 1-year survival was 88% and 2-year survival was 75%.ConclusionIn well-selected patients referred to a specialized institution, CS-HIPEC has an acceptable morbidity and high survival rate.
