Brief summary:
The proposed study aims to investigate how the administration of a drug known to reduce inflammation in humans, Celecoxib, will effect the peri-operative inflammatory response of a patient undergoing primary tumor resection surgery for colon cancer. The proposed project is an exploratory study, and will use data from blood samples and tumor samples to attempt to elucidate the immune and inflammatory response in colon cancer patients undergoing primary resection of their tumors.

Detailed description:
This study is the first to assess the perioperative time course of systemic inflammation and immunity in colon cancer patients and evaluate the effect of anti-inflammatory treatment with celecoxib on this response. In addition, evaluation of the effect of short-term preoperative administration of celecoxib on tumor immunogenicity will help us to understand how tumor-enhancing inflammation and anti-tumor immunity can be differentially affected by COX-2 inhibitors. The knowledge gained as a result of this research will help us to set up the infrastructure for a method to monitor the immunoinflammatory status of colon cancer patients with a longer term goal of designing interventions to suppress tumor-enhancing inflammation and vitalize anti-tumor immunity in the perioperative period. The long-term objective is to use these novel tools in order to improve cancer-specific survival in patients with colon cancer after primary tumor resection.
