Abstract

OBJECTIVES
This study was aimed to analyze the trends of cancer incidence and evaluate the quality control of cancer registration data in Jeollabuk-do from 2001 to 2010.
METHODS
Incidence data of all cancers and indices of quality of cancer registration data in Jeollabuk-do for the 10-year period were obtained from the Population-based Regional Cancer Registry in the Jeonbuk Regional Cancer Center. Trends in crude incidence rate (CR) and age-standardized incidence rate (ASR) for all cancers and incidence rates for major cancer sites by gender were analyzed. Joinpoint regression tool was used to describe and quantify trends. And the completeness and validity of cancer registration data were analyzed.
RESULTS
The major cancer sites in males were the stomach (22.2%), lung (16.6%), colorectum (12.8%), liver (12.3%) and prostate (6.2%), and in females were the thyroid (17.8%), stomach (14.7%), breast (11.6%), colorectum (11.5%) and lung (7.7%). Between 2001 to 2010, ASR for all cancers increased 13.7% in men, 68% in women, and 36.5% overall. ASR for all cancers increased by 1.2% per year in males and by 6.7% per year in females from 2001 to 2010. In the quality control of the cancer registration data between 2001 and 2010, death certificate only (DCO%) for men was decreased from 5.6% to 1.3% and DCO% for women decreased from 6.1% to 1.8%. Microscopic verification (MV%) increased in both men and women. And mortality/incidence ratio (MI%) declined in both men and women.
CONCLUSIONS
The Cancer Incidence During The 10 Years (2001-2010) In Jeollabuk-do Was Increasing Especially For The Colorectum And Prostate In Men, And For The Thyroid And Breast In Women. The Overall Quality Control Of The Cancer Registry Was Gradually Improving.
