Abstract

Background: Cancer remains a leading cause of premature mortality among women in India, with wide disparities in access to care and staging at diagnosis. Hospital-Based Cancer Registries (HBCRs) provide clinical insights into cancer case profiles among patients attending tertiary institutions. Integrating Geographic Information System (GIS) with HBCR data offers a novel opportunity to visualize cancer case distributions within hospital catchment areas. The objective was to evaluate the feasibility of integrating GIS with HBCR data to map women’s cancer distribution and staging in Mysuru District, Karnataka.

Methodology: A retrospective descriptive study was conducted using HBCR data from January 2019 to December 2022. Confirmed cancer cases among women with valid addresses were included. Sociodemographic and clinical data were analyzed using SPSS. Geographic coordinates were geocoded using Google Earth Pro and mapped using ArcGIS to visualize spatial patterns.

Results: Most cases occurred among middle-aged women, with breast, gynecological, and gastrointestinal cancers being predominant. Over two-thirds of cases were diagnosed at early stages. Spatial mapping revealed clustering of cases near urban centers, while brain and CNS cancers showed a higher proportion of late-stage presentation in rural areas.

Conclusion: Integrating GIS with HBCR data is a feasible method for visualizing cancer patterns and staging. This approach can support institutional planning, though findings are not population-representative.
