Objective: To evaluate the preoperative systemic immunity-inflammation index (IIS) as a predictor of metastasis in patients with colon cancer and to determine postoperative risk factors for metastatic colon cancer. Material and methods: This analytical study of diagnostic and case-control tests nested in a cohort included 93 post-operative patients (46 cases and 47 controls) randomazed selected from colon cancer between 2014 and 2018. Bivariate analysis was performed using the t test and chi-square considering a p value <0.05. In the evaluation of the risk factors, OR and 95% CI were used. The IIS was calculated using the ROC curve finding its optimal cut-off point, as well as the sensitivity, specificity and predictive values. Results: The preoperative IIS was higher in those who had colon cancer metastases (1070.8 vs 645.8, p <0.001). The analysis of the ROC curve determined that the best cut-off point of the preoperative IIS was 528.5. The IIS presented a sensitivity of 84.8%, specificity of 63.8%, positive predictive value of 69.6% and negative of 81.1% in the diagnosis of colon cancer. Patients with a higher IIS value at the colon cancer cut-off point had a higher risk of metastasis (OR: 9.83, p <0.001). Regarding the intervening variables, there was a higher proportion of men with metastases (OR: 2.5, p = 0.049), and the most frequent location was the left colon (OR: 3.11, p = 0.009). Finally, the multivariate analysis shows as the only independent factor the IIS with OR: 9.51 and 95% CI: 3.19 - 25.14. Conclusions: A preoperative systemic immunity-inflammation index (IIS) is a predictor of metastasis as well as being a postoperative risk factor for colon cancer. The preoperative IIS together with the left location of the cancer and the male sex are postoperative risk factors for metastatic colon cancer.
