- Abstract
Objective: To describe incidence, mortality and survival trends from oral cancer (OCa) in Cali, Colombia during the period of 1962-2007. Methods: Age-standardized incidence rates (world population) (ASIR) and mortality (ASMR) for oral cancer were obtained with information from the Cancer Registry in Cali, Colombia (RPCC, Spanish acronym) and from the Secretariat Municipal Public Health in Cali (SSPM, Spanish acronym). We used the annual percentage of change (APC) to describe these trends. Kapplan Meier curve comparisons and Cox's model for proportional risks were used to evaluate survival and estimate proportional risks. Results: There were 1637 new cases of oral cancer registered and the average age at the time of diagnosis was 60 years. The ASIR declined in men between 1962-2007 (APC = -1.3 (95% CI: -2.0, - 0.6) and among women (APC = -1.0 (95% CI: -1.7, -0.4). The ASMR decreased only in men between 1984-2001 (APC = -2.8 (95% CI: -4.1, -1.5). The relative survival rate for oral cancer after five years in Cali was 55.5% (95% CI: 50.9-59.9). Conclusions: The morbidity and mortality rates for oral cancer have significantly decreased in Cali, Colombia. The type of tumor associated with these changes was the squamous cell carcinoma.
