Significance: Determine the incidence, prevalence and yearly mortality rates for colorectal cancer in Metro Cebu from January 2002 to December 2012 and the10 year-mortality and 5- year survival rates.
Methodology: This is a descriptive retrospective epidemiologic study of all colorectal cancer cases from 2002 to 2012 using the registry files in Metro Cebu from Eduardo J. Aboitiz Cancer Center Registry. The number of cases was classified according to the specific town or city of residence per year. The incidence rates for each town or city and the prevalence rate for the year 2012 were determined, including the yearly mortality rates, 10-year mortality rate, risk analysis as to the intervention given and five year-survival rates based on intervention. Response to treatment was computed using relative risk and risk difference. For survival rate, Kaplan-Meier analysis was used. Categorical data were expressed in frequency and percentages. The response to treatment based on the mode of intervention given was computed using relative risk and risk difference. For the 5-year survival rate of colorectal cancer, Kaplan-Meier analysis was used.
Results: There are 2621 cases; with the male sex predominating. Majority of age range is from 60 to 69 years old. Surgery is the most common intervention. Cebu City has the highest prevalence rate. The highest mortality rate was noted in Compostela in 2011. The 5-year survival rate is 30.9%. The 5 year- survival rate is 50% and those who receive surgery is only at 15.4%.
Conclusion: This study reflects the current trends of colorectal cancer in the Asia Pacific.
