title: Cancer survival in Seoul, Republic of Korea, 1993-1997.
abstract: The Seoul cancer registry was established in 1991. Cancer is a notifiable disease, and registration of cases is done by passive and active methods. The registry contributed survival data for 56 cancer sites or types registered during 1993-1997. Follow-up information has been gleaned predominantly by passive methods with median follow-up ranging between 5-82 months for various cancers. The proportion with histologically verified diagnosis for different cancers ranged between 23-99%; death certificates only (DCOs) comprised 0-67%; 33-100% of total registered cases were included for survival analysis. The top-ranking cancers on 5-year age-standardized relative survival rates were testis and placenta (95%), thyroid (93%), non-melanoma skin (93%), corpus uteri (79%), renal pelvis (77%), cervix (76%), Hodgkin lymphoma (75%), breast (74%) and prostate (74%). Five-year relative survival by age group showed a decreasing trend with increasing age groups for cancers of the small intestine, colon, gall bladder, cervix, corpus uteri, ovary, kidney, urinary bladder and thyroid, or was fluctuating for other cancers.
