title: Cancer survival in Lampang, Thailand, 1990-2000.
abstract: The Lampang cancer registry was established in 1995, with retrospective data collection since 1988. Cancer registration is currently done by passive methods. The registry is contributing data on survival for 40 cancer sites or types registered during 1990-2000. Follow-up has been carried out by passive and active methods with median follow-up ranging from 1-74 months for different cancers. The proportion having a histologically verified diagnosis for various cancers ranged between 30-100%; death certificate only (DCO) cases comprised 0-33%; 67-100% of total registered cases were included for survival analysis. Complete follow-up at five years ranged from 96-100% for different cancers. The 5-year age-standardized relative survival rate was the highest for skin non-melanoma (85%) followed by lip (81%), thyroid (74%), corpus uteri (71%) and penis (71%). The 5-year relative survival by age group showed a fluctuating trend. An overwhelmingly high proportion of cases were diagnosed with a regional spread of disease, ranging from 35-68% for different cancers, and survival was decreasing with increasing extent of disease for most cancers studied.
