Abstract

Based on a citizen's report, a house-to-house survey was conducted in Talwandi Sabo and Chamkaur Sahib Community Development Blocks in Bathinda and Roop Nagar District respectively in Punjab state located in a northern part of India to identify the number of existing cancer cases, and the number of cancer deaths that occurred in the last 10 years. Age adjusted prevalence of confirmed cancer cases per 100,000 population was 125 (107/85315) in Talwandi Sabo and 72 (71/97928) in Chamkaur Sahib. Cancer of female reproductive system, i.e., breast, uterus/cervix and ovary were more common in Talwandi sabo whereas cancer of blood and lymphatic system, esophagus, and bones were more common in Chamkaur Sahib. Cancer deaths per 100,000 populations per year were 52 in Talwandi Sabo compared to 30 at Chamkaur Sahib. A comparison of the characteristics of randomly selected individuals, from the villages where a cancer case existed or death due to cancer had occurred in last 2 years, revealed that involvement in cultivation, pesticide use, alcohol consumption and smoking were more common in Talwandi Sabo as compared to Chamkaur Sahib. Limited studies show that in drinking water the levels of heavy metals such as As, Cd, Cr, Se, Hg were generally higher, and pesticides such as heptachlor, ethion, and chloropyrifos were also higher in samples of drinking water, vegetables, and blood in Talwandi Sabo as compared to Chamkaur Sahib. As multiple factors were responsible for significantly higher prevalence of cancer cases in Talwandi Sabo, therefore, a multi-pronged strategy to discourage the indiscriminate use of pesticides, tobacco and alcohol needs to be adopted for cancer prevention, and a cancer registry should be set up for elucidation of the role of pesticides and heavy metals in the etiology of cancer in this area.

摘要

根据一名市民的报告,分别在印度北部旁遮普邦巴辛达县的塔尔万迪萨博和鲁普纳加尔县的查姆考尔萨希卜社区发展区进行了挨家挨户的调查,以确定现有的癌症病例数量以及过去10年中发生的癌症死亡人数。塔尔万迪萨博每10万人口中经确认的癌症病例年龄调整患病率为125(107/85315),查姆考尔萨希卜为72(71/97928)。女性生殖系统癌症,即乳腺癌、子宫/宫颈癌和卵巢癌在塔尔万迪萨博更为常见,而血液和淋巴系统癌症、食道癌和骨癌在查姆考尔萨希卜更为常见。塔尔万迪萨博每年每10万人口中的癌症死亡人数为52,而查姆考尔萨希卜为30。对过去两年中出现癌症病例或因癌症死亡的村庄中随机挑选的个体特征进行比较后发现,与查姆考尔萨希卜相比,塔尔万迪萨博从事耕种、使用农药、饮酒和吸烟的情况更为普遍。有限的研究表明,与查姆考尔萨希卜相比,塔尔万迪萨博的饮用水、蔬菜和血液样本中,砷、镉、铬、硒、汞等重金属以及七氯、乙硫磷和毒死蜱等农药的含量普遍较高。由于多种因素导致塔尔万迪萨博的癌症病例患病率显著更高,因此,需要采取多管齐下的策略来劝阻人们滥用农药、烟草和酒精以预防癌症,并且应建立癌症登记处以阐明农药和重金属在该地区癌症病因中的作用。
