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.
