The Bhopal population-based cancer registry was established in 1986 under the national cancer registry programme to investigate the after-effect of a gas leak in 1984. Cancer registration is done entirely by active methods. The registry is contributing data on survival for 16 cancer sites or types registered during 1991-1995. Follow-up of cases was done by active methods with median follow-up time ranging between 8-44 months for different cancers. The proportion with histologically verified diagnosis for various cancers ranged between 61-100%; death certificates only (DCOs) comprised 0-2%; 50-92% of total registered cases were included for survival analysis. The 5-year age-standardized relative survival rates for common cancers were mouth (34%), cervix (31%), breast (25%), tongue (12%), oesophagus (3%) and lung (1%). The 5-year relative survival by age group showed that survival was the highest in the youngest age group (45 years and below) for a majority of cancers. A decreasing survival with increasing clinical extent of disease was noted for most cancers studied.
博帕尔基于人群的癌症登记处于1986年在国家癌症登记计划下设立，旨在调查1984年一次气体泄漏的后续影响。癌症登记完全通过主动方法进行。该登记处正在提供1991 - 1995年期间登记的16种癌症部位或类型的生存数据。病例随访通过主动方法进行，不同癌症的中位随访时间在8 - 44个月之间。各种癌症经组织学证实诊断的比例在61% - 100%之间；仅死亡证明（DCOs）占0% - 2%；纳入生存分析的登记病例总数的比例为50% - 92%。常见癌症的5年年龄标准化相对生存率分别为口腔癌（34%）、宫颈癌（31%）、乳腺癌（25%）、舌癌（12%）、食管癌（3%）和肺癌（1%）。按年龄组划分的5年相对生存率显示，大多数癌症在最年轻年龄组（45岁及以下）的生存率最高。在所研究的大多数癌症中，观察到随着疾病临床分期的增加生存率下降。
