The Chiang Mai tumour registry was established in 1978 as a hospital-based cancer registry, and population-based cancer registration started in 1986, with retrospective data collection on cancer incidence and mortality since 1983. Registration of cases is done by active methods. Data on survival for 36 cancer sites or types registered during 1993-1997 are reported here. Follow-up has been carried out predominantly by active methods, with median follow-up ranging between 1-39 months for different cancers. The proportion of histologically verified diagnosis for various cancers ranged between 28-100%; death certificate only (DCO) cases comprised 0-56%; 33-92% of total registered cases were included for survival analysis. Complete followup at five years ranged from 59-100% for different cancers. The 5-year age-standardized relative survival rates was the highest for Hodgkin lymphoma (70%) followed by thyroid (65%), cervix (57%), breast (56%) and corpus uteri (49%). The 5-year relative survival by age group showed either an inverse relationship or was fluctuating. An overwhelmingly high proportion of cases were diagnosed with a regional spread of disease, ranging between 44-82% for different cancers and survival decreased with increasing extent of disease for all cancers studied.
清迈肿瘤登记处成立于1978年，是一个基于医院的癌症登记处，基于人群的癌症登记始于1986年，自1983年起开始回顾性收集癌症发病率和死亡率数据。病例登记通过主动方法进行。本文报告了1993 - 1997年期间登记的36个癌症部位或类型的生存数据。随访主要通过主动方法进行，不同癌症的中位随访时间在1 - 39个月之间。各种癌症经组织学证实诊断的比例在28% - 100%之间；仅死亡证明（DCO）病例占0% - 56%；纳入生存分析的病例占总登记病例的33% - 92%。不同癌症的五年完全随访率在59% - 100%之间。霍奇金淋巴瘤的5年年龄标准化相对生存率最高（70%），其次是甲状腺癌（65%）、宫颈癌（57%）、乳腺癌（56%）和子宫体癌（49%）。按年龄组划分的5年相对生存率呈反比关系或波动变化。绝大多数病例被诊断为疾病区域扩散型，不同癌症的这一比例在44% - 82%之间；在所研究的所有癌症中，生存率随疾病范围扩大而降低。
