Manejo de carcionomatosis peritoneal con citorreducción más quimioterapia hipertérmica intraoperatoria (hiped)

Introduction: cytorreductive surgery (CRS) paired with hyperthermic intraoperative chemotherapy (HIPEC), approach peritoneal carcinomatosis (PC) as a localized regional disease with adequate survival response according to disease severity. CRS with HIPEC is regarded as a highly morbid procedure with high mortality rates. Objective: to review the 1-year overall survival and disease-free survival in patients with PC that had been treated with CRS with HIPEC at Hospital Infantil Universitario de San Jose between January 2016 and December 2017. Methodology: an observational study analyzing a cohort of patients with PC secondary to various primary tumors who received CRS with HIPEC. Data was collected from clinical records. Results: we included 10 cases with mean age of 49 years (IQR 43-54) and PC secondary to appendix (60%, n=6), colon (20%, n=2) and ovary (20%, n=2) primary tumors. The peritoneal carcinomatosis index (PCI) was 14.5 (IQR 6-24). PC recurred in 3 patients and 4 patients died. A 1-year overall survival rate of 54% was estimated and a 1-year disease-free survival of 58% was obtained. Conclusion: our results of 1-year overall and disease-free survival rates were better to those described for systemic chemotherapy. Strict patient selection, as well as, conducting larger studies is recommended to allow an evidence-based determination of overall and disease-free survival in patients treated with CRS with HIPEC.
