Abstract
Objectives: To estimate the cancer incidence by age group and gender for the population of Karachi Division by analyzing the Karachi Cancer Registry data of 2017-19. Settings: The population of Karachi division is 16.1 million according to national census 2017. ‘Karachi Cancer Registry’ which is a part of ‘National Cancer Registry’ is collecting data from eight major hospitals in Karachi since 2017. For outcome measures, cancer counts and the age standardized incidence rates (ASIR) per 100,000 population were computed for age groups (0–14, 15–19 and ≥20 years), in both genders and all cancer site/type. Methods: The population denominators were based on the population of Karachi division estimated at 16.1 million in the population census, 2017. Counts and age-standardized incidence rates (ASIR) were calculated for each of the three age categories. Results: From Jan 2017 till Dec 2019 a total of 33,309 malignant cases were recorded in KCR database comprising 17,490 (52.5%) females and 15,819 (47.5%) males. ASIRs in age groups 0-14, 15-19 and ≥ 20 years, among female were 11.5, 2.4 and 223.6 and in males were 17.6, 3.2 and 216.7 respectively. The commonest diagnosis in children, adolescent and adults were (1) among females: children; bone (3.12), leukemia (2.09) brain/CNS (1.26); in adolescents: bone (0.78), brain/CNS (0.27), connective and soft tissue (0.11), in adults: breast cancer (76.07), oral cancer (16.68) and ovary (10.89) respectively, and (2) among males: children; bone (4.56), leukemia (2.79) and brain/CNS (1.88); in adolescent; bone (1.19), brain/CNS (0.31) and leukemia (0.21) and in adults: oral cancer (42.83), liver (16.10) and bone (13.37) respectively. Conclusion: Oral Cancer, a largely preventable cancer is the leading cancer in Karachi adult males while in female adults Breast Cancer is the leading cancer followed by Oral Cancer. In children and adolescents Bone, Leukemia and Brain/CNS malignancies are most common.
