Epidemiologic and survival characteristics of patients with colorectal cancer in Ege University medical faculty database

Abstract

Aim: The aim of this study was to determine epidemiological and overall survival (OS) characteristics of colorectal cancer (CRC) patients. Materials and Methods: Data of Ege University Cancer Control and Research Center between 1992- 2017 were screened retrospectively. Data recorded in CANREG program were grouped and analyzed in WHO and SEER systems. Chi-square test, General Linear Model (GLM) and Kaplan-Meier survival analysis were used for statistical analysis. Results: Number of CRC cases were 7285 (6.2%) among 117139 cancer cases. CRC ranked 7th among all the cancer types. Of the CRC patients, 4330 (59%) were male. The most common localization was rectum (38.4%). CRC increases with age. A significant increase was found at the age of 60 years and older (p=0.022) among both genders, but the difference between genders was not significant (p=0.299). Linear increase over the years was significant in total (GLM: F=12,349; p<0.0001). Adenocarcinoma (86%) was the most common histologic type, 54.2% of patients were diagnosed at locally advanced stage. The 5-year OS rate was 66.4% in locally advanced cancer and 15.8% in case of distant metastasis (p<0.0001). Median survival was 69 months, 5 and 10-year OS rates were 53% and 40% respectively. Ten-year OS was significantly higher in women. Five and 10- year OS rates were significantly lower in ≥70-year-old age group, and subsequently in the 20-29 years age group if ≥70-year-old age group was not taken into account (p<0.0001). Conclusion: There is an increase in CRC over the years, and generally the patients were diagnosed in locally advanced stages. The 5-year OS rate was 54.5% in the 60-69 age group which accounts for the most common age group, Ten-year OS rate was 43.3% in women which was higher than in men. Histology and stage were the most important prognostic parameters in prognosis.
