Survival and prognostic factors among hospitalized pancreatic cancer patients in northwestern Iran

BACKGROUND: Pancreatic cancer (PC) is associated with a poor prognosis, with various modifiable risk factors affecting the survival of patients. Our aim was to evaluate the survival rate and the prognostic factors influencing survival in PC patients in northwestern Iran. MATERIALS AND METHODS: All the PC patients admitted to the Imam Reza Hospital of Tabriz, Iran, from 2016 to 2020, were enrolled in this study. The survival rate and time were calculated, and the risk factors related to survival were evaluated by Cox regressions. The data were analyzed using the Cox proportional hazards model using STATA software. RESULTS: Of 110 patients, 12-, 24-, 36-, and 48-month survival rates were 29.1%, 19.8%, 14.1%, and 8.5%, respectively, with the median survival time of seven months. The mean age was 65.5 years. The results showed that a higher age (hazard ratio [HR] [95% confidence interval (CI)] = 2.04 [1.20–3.46]), lower education (1.72 [1.03–2.89]), delayed diagnosis (1.03 [1.02–1.05]), hypertension (1.53 [1.01–2.31]), concomitant heart disorders (2.67 [1.50–4.74]), COPD (4.23 [1.01–17.69]), consanguineous marriage (1.59 [1.01–2.50]), and the presence of icterus complications (adjusted HR = 3.64 [1.56–8.49]) were directly associated with a worse survival. On the contrary, radiotherapy (0.10 [0.01–0.85]), chemotherapy (0.57 [0.36–0.89]), and surgical therapy (AHR = 0.48 [0.23–0.99]) were directly related to a good prognosis. CONCLUSION: Surgery, chemotherapy, and radiotherapy were the best predictors of survival in PC patients. Moreover, it seems that resolving jaundice can improve survival in these patients. It seems that increasing social awareness, treating underlying diseases, and employing an appropriate therapeutic method may promise a better outlook, improve the survival rate of patients, and reduce PC risk.
