The Effect of Preoperative Waiting Time on Prognosis and Outcome of Colorectal Cancer Patients: Retrospective Cohort Analysis.

Background: Colorectal cancer (CRC) was identified as the 3rd most frequent type of malignancy on the globe. The postoperative outcomes as well as prognosis of CRC individuals are influenced by factors such as age, type 2 diabetes mellitus (T2DM) and postoperative complications in addition to tumour stage. Objective: This study aimed to assess how preoperative waiting time affects CRC individuals' immediate results and prognosis. Patients and methods: Our research involved 80 individuals with CRC of all grades and stages who underwent major colorectal cancer surgery at Sohag University's Oncology Department in Egypt. Data included age, body mass index (BMI), sex, comorbidities, tumor site, clinical stage, and several tests such as colonoscopies, barium enemas, flexible sigmoidoscopies, abdominal computed tomography scans (CT), X-rays, ultrasounds, and fecal occult blood. Group 1 (n=43) had a waiting time of less than a month, group 2 (n=26) among 1-2 months, and group 3 (n=11) > two months. Results: The univariate logistic regression analysis identified age, clinical stage, T2DM, BMI, overall complications, as well as serious complications as significant predictors of overall survival. The univariate logistic regression analysis identified clinical stage, age, major complications & overall complications as significant predictors of disease-free survival. Conclusions: The duration of waiting did not have an influence on the immediate results or prognosis for individuals with CRC. There is a need for a substantial amount of data to evaluate the consequence of preoperative waiting time on the consequences of CRC cases, to enhance the reliability of the findings.
