Five-year survival in laparoscopically operated colorectal cancer patients based on own material: A comparison of risk factors.

Abstract

<b>Introduction:</b> The laparoscopic method is a treatment method with proven effectiveness. In 2008, we started treating patients with this method. We present treatment results in unselected patients. This is a retrospective observation.<b>Aim:</b> The present article demonstrates the results of a 5-year postoperative follow-up in a group of patients who underwent laparoscopic colorectal surgery. We also assessed the importance of basic risk factors such as tumor stage, age, gender, type of complication, and conversion requirement for the survival of patients.<b>Material and methods:</b> In total, 212 patients with colon or rectal cancer were subjected to a standard laparoscopic procedure. In the case of rectal and sigmoid tumors, a mini-laparotomy was performed in the left iliac fossa. In the case of right hemicolectomy, an anastomosis was created above the abdominal walls. The results were statistically processed. As many as 80% (171) of patients were followed up.<b>Results:</b> Overall survival was 66.08%, while cancer-related survival - 61.4%. The cancer recurrence rate was 21.47%. In a multivariate analysis: assuming the same age of diagnosis, an increase in tumor stage by one category according to Dukes causes a 102.532-fold increase in the risk of death within the first 5 years after surgery.<b>Conclusions:</b> The results of laparoscopic colorectal cancer treatment in our material are similar to those reported in the literature. The most important prognostic factor for the long-term survival of patients in our material was the stage of cancer.
