ABSTRACT
BACKGROUND:
Rectal cancer (RC) poses a significant global health challenge, causing substantial morbidity and mortality. This study aims to investigate the survival rates of RC patients and identify the factors that influence their survival. The study considers demographic characteristics, tumor features, and treatment received as the factors under consideration.METHODS:
A retrospective analysis was conducted on the medical records of 593 RC patients. Data were collected through a comprehensive review of medical records and conducting telephone interviews. Survival rates were estimated using the life table method, and subgroup comparisons were performed using the log-rank test. Cox regression analysis was utilized to assess the independent associations between RC survival time and various covariates.RESULTS:
The study cohort comprised 593 RC patients, with a predominantly male representation. The mean age at diagnosis was 58.18 years, and the majority of patients (78.6 %) underwent surgical interventions. The median age at symptom onset and diagnosis were 58 and 59 years, respectively. Survival rates at 1st, 3rd, 5th, and 10th years were estimated to be 85 %, 59 %, 47 %, and 36 %, respectively. Statistical analysis revealed several significant prognostic factors, including age, education, symptoms, and cancer stage. In the multivariate Cox proportional-hazards analysis, advanced regional stage (HR = 1.54, 95 % CI, 1.13-2.08), presence of metastasis (HR = 3.73, 95 % CI, 2.49-5.58), and age over 70 (HR = 1.65) were associated with a higher risk of mortality.CONCLUSION:
Given the alarming prognosis of RC observed in the study area and the significant delay between symptom onset and diagnosis, it is crucial to address this issue and potentially improve the survival rates of RC patients.Palavras-chave
