An Institution-Based Demographic Study of Urinary Bladder Cancer from North India.

Urinary bladder cancer (UBC) is among the top ten cancers worldwide. Incidence is rising mainly attributed to environmental contamination due to chemical carcinogens and smoking habits. Recently, we have seen a higher number of UBC patients and thus aim to study the associated epidemiological parameters. This was a single-center retrospective analysis that involved histology-proven UBC patients presented from the inception of medical oncology services. Clinical, demographic data and history of exposure to potential risk factors were noted. A telephonic interview with the patient or family members was conducted for the missing data. Mean age of patients was 60.36 ± 10.33 years. More than half of the patients were of the geriatric age group. Males were affected 7.5 times more as compared to females. Sixty-four percent of the patients were smokers. Seventy-three percent of the patients had a residence in the plains or Terai region. Thirty percent of the patients reported farming as their occupation. Anthranilic diamide, chlorpyriphos cypermethrin, lesenta (imidacloprid + fipronil), and tricyclazole were the commonly used insecticides/pesticides. Untreated groundwater, river, or pond was the source of drinking water for 68% of the patients. The insecticides/pesticides used in agriculture and the subsequent contamination of food and water serving as the vehicle for the potential carcinogens need a critical review and are hypothesis-generating. © Indian Association of Surgical Oncology 2022.
