Is advanced age a hesitation for cytoreductive surgery and hyperthermic intraperitoneal chemotherapy in colorectal cancer?

Purpose: The purpose of this study was to assess the feasibility and safety of cytoreductive surgery (CRS) and hyperthermic intraperitoneal chemotherapy (HIPEC) in elderly patients with peritoneal carcinomatosis of colorectal cancer. Methods: Patients who underwent curative complete CRS and HIPEC for peritoneal carcinomatosis of colorectal cancer with minimum follow-up of 24 months were included in the analysis. Charlson comorbidity index and ECOG performance status were used to evaluate preoperative condition. Patients were tiered into two groups according to age (<65 and >= 65 years). Postoperative morbidity, mortality, recurrence, and overall survival were compared between groups. Results: One-hundred patients were meeting the inclusion criteria. Median age was 56 years (ranging, 20-86). The origin of peritoneal carcinomatosis (PC) was colon in 77 and rectum in 23 patients. There were 31 patients in the elderly group. Mean hospital stay was 17 +/- 11.8 and 16.8 +/- 14.3 days in young and elderly groups (p=0.937). In young patients, postoperative morbidity was seen in 26 (37.6%) patients versus 9 (29%) patients in elderly group (p=0.272). Mortality was higher in elderly group (n=4, 12.9%) than in the younger group (n=5, 7.2%), but the difference was not statistically significant (p=0.287). Median follow-up was 25 months (ranging, 2-112). Local and/or distant recurrence occurred in 30 (43.4%) patients in the young group and 9 (29%) patients in elderly group (p=0.169). Two-years disease-free survival was similar: 67.1% in the young and 74% in the elderly groups (p=0.713). Conclusions: CRS and HIPEC offer comparable oncologic outcome in meticulously selected medically-fit elderly patients without increased postoperative morbidity and mortality.
