Incidence and age-standardized rates of pancreatic cancer in Sri Lanka from 2001 to 2010: An analysis of national cancer registry data

Indian J Cancer. Jul-Sep 2021;58(3):387-393. doi: 10.4103/ijc.IJC_238_19.

Abstract

Background: Varying trends in the incidence of pancreatic cancer (PC) are observed in many Asian countries. This study aimed at describing the incidence and age-standardized rates of PC in Sri Lanka from 2001-2010.

Methods: A retrospective cohort evaluation of patients with PC from 2001 to 2010 was performed using the population-based data published by the Sri Lanka National Cancer Registry. The trends in the incidence of PC was analyzed by age and sex using joinpoint regression analysis.

Results: A total of 808 PC patients studied from 2001-2010, of which males were 438 (54.2%). The mean (±standard deviation) age of the total population was 55.7 (±13.8) years [males = 56.5 (±13.3) vs. females = 54.8 (±14.3), P=0.07]. The World Health Organization (WHO) age-standardized incidence of PC in Sri Lanka increased marginally from 0.44 per 100,000 in 2001 (95% confidence interval (CI) = 0.34-0.54) to 0.58 per 100,000 in 2010 (95% CI = 0.46-0.69) which is a 1.3-fold increase (P < 0.05 for trend) with an estimated annual percentage change (EAPC) of 3.5 (95% CI = 0.5-6.6). The proportional increase in incidence was more significant in females compared to males. The analysis of the overall cohort rates of PC in Srilanka between 2001-2010 showed the highest rates in the 60-70-year category with an EAPC of 5.06 (95% CI = 1.3-9.0).

Conclusion: In our study, we found that there was a marginal rise in the incidence of PC in Sri Lanka with a higher proportional increase in females compared to males.
