Effect of preoperative immunonutrition on postoperative major morbidity after cytoreductive surgery and hipec in patients with peritoneal metastasis

3565 Background: Major morbidity (MM) after cytoreductive surgery with heated intraperitoneal chemotherapy (CRS/HIPEC) is associated with worsening of disabilities and length of the hospital stay. This study aimed to identify MM prognostic factors and to measure its impact on oncological outcomes. Methods: A post-hoc analysis of a prospective cohort of 734 patients with peritoneal metastasis (PM) from 2006 to 2015 was undertaken. Five hundred and two patients who had complete CRS and HIPEC for PM were included. Results: Major morbidity was identified in 31% (156/502) of CRS/HIPEC procedures, including 67 hemorrhagic complication (13.3%), 87 anastomotic leaks (17.4%), 121 reoperation (24.1%), and 65 pulmonary complication (12.9%). The multivariate predictors of MM were American Society of Anesthesiologists (ASA) score (ASA 3 vs. 1-2, 0R 95%CI: 3.58 [1.54 – 8.34]), origin of PM colorectal adenocarcinoma vs. other, OR 95%CI: 1.62 [1.06 – 2.48]), type of HIPEC drug (oxaliplatin vs. other, OR 95%CI: 2.85 [1.28 – 6.32]), number of anastomosis (no vs. at least 1, HR 95%CI: 1.85 [1.19 – 2.88]), blood transfusion (OR 95%CI: 1.84 [1.05 – 3.23]) and length of surgery longer than the median value (OR 95%CI: 1.88 [1.22 – 2.91]). The in-hospital mortality rate for the entire cohort was 1.7% (9/502). Rate of adjuvant chemotherapy after CRS/HIPEC was comparable between the two groups (70.3% vs. 72.4%, p = 0.64). The median duration of follow-up was 18 months. The MM group had worst OS and DFS comparing non-MM (Hazard ratio and 95% confidence interval at 3.48 [1.90 ; 6.35] and 1.91 [1.43 ; 2.57], respectively). Conclusions: Major morbidity after CRS/HIPEC for peritoneal metastasis is a source of significant reoperation and longer hospital and intensive care unit stay; with a decrease in overall survival and disease free survival even after complete CRS. Preoperative ASA score, number of anastomoses, colorectal origin of PM, HIPEC with oxaliplatin, blood transfusion and length of surgery are independent predictors of MM for CRS/HIPEC patients.

Peritoneal Cancer

AbstractPeritoneal metastasis from colorectal cancer (PM-CRC) is used to be considered a systemic and fatal condition; however, it has been growingly accepted that PM-CRC can still be local disease rather than systemic disease as analogous to liver or lung metastasis.Cytoreductive surgery (CRS) combined with hyperthermic intraperitoneal chemotherapy (HIPEC) is now considered an optimal treatment for PM-CRC with accumulating evidence. There is a good reason that CRS + HIPEC, widely accepted as a standard of care for pseudomyxoma peritonei (PMP), could be a viable option for PM-CRC given a similarity between PM-CRC and PMP.Recent years have also seen that modern systemic chemotherapy with or without molecular targeted agents can be effective for PM-CRC. It is possible that neoadjuvant or adjuvant chemotherapy combined with CRS + HIPEC could further improve outcomes.Patient selection, utilizing modern images and increasingly laparoscopy, is crucial. Particularly, diagnostic laparoscopy is likely to play a significant role in predicting the likelihood of achieving complete cytoreduction and assessing the peritoneal cancer index score.
