Abstract PDF: PURPOSE
To ascertain the factors associated with the proportion of death certificate only (DCO) cases contained in the Kwangju Cancer Registry (KCR) that are not as yet in the good range.
MATERIALS AND METHODS
The distribution of DCO cases was analyzed by sex, age, cancer site, histological verification (HV) as well as the physician's death certificate status.
RESULTS
All cases (n=4,243) in Kwangju diagnosed as having cancer between 1997 and 1998 were registered with the KCR. Death certificates (n=2,390) reporting cancer as the causes of death were collected from the National Statistics Office and reviewed with hospital data linkage and a total of 590 cases were registered as DCO. DCOs accounted for 12.2% (male 12.8%, female 11.5%) of all registrations in Kwangju, 1997~1998. The proportion of DCO cases was high in subjects under 15 (male13.5%,female 9.4%) as well as those 75 and over (male 20.3%, female 27.2%). For cancer sites, the proportion of DCO cases was high (over 10%) for liver, bronchus-lung, esophagus and pancreas and low (under 3%) for skin, bladder, uteri cervix and breast. The proportion of DCO cases was inversely associated with HV%. When the death certificate was issued by physician, the possibility of DCO decreased.
CONCLUSION
The proportion of DCO is positively associated with increasing age and negatively associated with HV% and the issuance of a physician's death certificate. These findings suggest that further socio-cultural efforts are required to reduce the DCO proportion.

A Feasibility Study for the Implementation of Kwangju Cancer Registry (KCR): Jin Su Choi, Seok Joon Shn, Baeg Ju Na, Byeong Hwan Sun, Kyeong Soo Park, Sun Seog Kweon, Jeong Soo Im, Young Jin Kim, Tai Ju Jwang; J Korean Cancer Assoc. 1999;31(4):749-757.

Abstract PDF: PURPOSE
This study was carrid out to assess the feasibility of cancer registry program (KCR) in Kwangju metropolitan city, Korea.
MATERIALS AND METHODS
The incidence cases and mortality data were mainly collected from the Korean national cancer registry system (NCR) and other resources such as medical insurance records, hospital records, pathology reports, radiation records and death certificates of 1996 in Kwangju metropolitan city.
RESULTS
This study identified 1,422 cases of cancer in 1996, which was about 1379o more than NCR. Cancer cases reported from the hospitals outside Kwangju metropolitan city reached almost 40% of total cases. Death certificate notification percent (DCN%) in 1996 was estimated about 31.1%. The proposed KCR would cover more than 95% of cancer cases in Kwangju metropolitan city.
CONCLUSION
The proposed KCR seems feasible in collecting cancer date with reasonable accuracy.
