Degree Project, Programme in Medicine, Colorectal cancer in a Sri Lankan teaching hospital, Sofia Lindskogen, 2020, Department of Surgery, University of Gothenburg, Sweden. Background: The economy in Sri Lanka has improved the last decades. Along with the prosperity of the country comes an increase in non-communicable diseases, such as colorectal cancer. Previous studies in South Asia suggests that the colorectal cancer differs in character from in the West regarding tumour location, age, tumour stage and survival. Aim: To compare patterns and long term outcome of colorectal cancer in a Sri Lankan hospital and two Swedish National Colorectal cancer Registers. Method: A retrospective medical record study including 185 patients diagnosed with colorectal cancer at Colombo South Teaching Hospital, Sri Lanka. Data was collected from the 5th of February to the 16th of Mars 2020. Swedish data was obtained from two National Colorectal Cancer Registers. Results: 18% of the patients were younger than 50 years old, a more than three times higher proportion than in Sweden (5%). The mean age differed with almost 10 years, 62 in Sri Lanka and 71 in Sweden. Tumour location was also different. 60% rectal and 40% colon tumours in Sri Lanka versus 29% rectal and 71% colon tumours in Sweden. 9 of the 68 patients that were followed for 5 years died and 13 encountered recurrence. The absolute 5-year survival was 88% and the risk for recurrence within 5 years was 24%. Corresponding Swedish numbers for 2 absolute 5-year survival was 82%, which resulted in no significant difference between the two countries. Conclusion: Differences could be detected between Sri Lanka and Sweden regarding age and tumour location, since Sri Lanka has a younger group of CRC patients with primarily rectal tumours. No statistically significant difference in absolute 5-year survival was found between the studied groups.
