Insulin Therapy Reduce Post-Operative Inflammatory Response After Curative Colorectal Cancer Resection: Randomization Controlled Trial

Summary

Research Problem: Surgical stress induces inflammation and postoperative immuno-suppression, which are risk. factors for both post-operative complication and possible disease recurrence. Colorectal cancer is in the top 5 malignancies in the Kingdome and the highest incidence in males. Recurrent disease locally or distally occurs in 35% of patients and is the leading cause of death in these patients. Despite the new era of laparoscopic surgery, still surgical stress is present and equally traumatic to the conventional open colorectal resection, earlier studies showed no major differences in post-operative inflammatory and immunological reactions. The previous studies revealed the anti-inflammatory effects of the hyper-insulinimic euglycemic therapy. Benefits observed in both major liver resection and in cardiac surgery. The anti-inflammatory effect reduced the surgical stress and postoperative inflammation. The hypothesis is "Can intraoperative hyper-insulinimic euglycemic infusion reduce post operative inflammation and immunomodulation in colon cancer patients undergoing a curative surgery?" Research methodology Triple blinded randomized controlled study with estimated sample size of 144 patients of non-metastatic colorectal cancer patients operated at King Saud University Medical city with a confirmed diagnosis of colon adenocarcinoma. Patients Consented will undergo computer randomization to receive intraoperative hyper-insulinimic normoglycemic infusion (experimental) or standardized insulin sliding scale and saline (control). A common preoperative and postoperative pathway with standardized management and pain control in both groups. Outcomes will be measured via a battery of laboratory test consist of routine labs, inflammatory markers and immunological markers to be repeated at fixed timed intervals. All patients will be followed by regularly for 5 years. Research objectives Primary outcomes to examine: * The anti-inflammatory effects of intraoperative hyper-insulinimic euglycemic therapy in patients undergoing colorectal cancer surgery. * The immunomodulatory effect of intraoperative hyper-insulinimic euglycemic infusion Secondary outcomes: * Thirty days post-operative morbidity. * Overall survival rate. * Disease-free survival rate.
