[Survival rates of the 5 major cancers in Jeju Island residents, 2000-2001].
OBJECTIVE
This study aimed to calculate the survival rates of cancer patients in Jeju Island residents from 2000 to 2001, based on their major primary sites of occurrence.


METHODS
Data were extracted from the database of the Jejudo Cancer Registry (JCR). The eligible population comprised 2,382 cancer cases, whose cancers were diagnosed from 1 January 2000 through 31 December 2001. Of the eligible population, 1,438 patients with 5 major cancers defined by the level of incidence rates were selected as the study participants. The period of survival for each case was calculated from the date of first diagnosis to the date of death, or the end of follow-up, i.e., 31 December 2003. The observed survival rates (OSR) and relative survival rates (RSR) were calculated according to sex, age-group, and primary sites of occurrence.


RESULTS
The 3-year OSR and RSR in 5 major cancers were higher in women than in men except 75 year-old over group. The 3-year RSR of stomach, colorectum, liver, and lung in both sexes were 61.0%, 62.6%, 24.7%, and 22.8%, respectively. The respective rates in JCR showed some statistically significant differences from those in the Korea Central Cancer Registry (KCCR).


CONCLUSIONS
These results would suggest some clues about prognostic factors of major cancers in Korean, and could apply to planning and evaluating of cancer control strategies in Jeju Island.
