Between 2012 and 2019, a total of 6,10 lakh cancers have been reported, with 52.4 percent and 47.6 percent respectively in men and women under the National Cancer Registry Program (NCRP).
Childhood cancer (0-14 years) comprised 7.9 percent of all cancers, according to the report titled “Clinicopathological Profile of Cancers in India: A Report of Hospital Based Cancer Registries, 2021”.
Cancers in sites linked to tobacco use comprise 48.7 percent of cancers in men and 16.5 percent in women, it said.
In 2012-19, a total of 13,32,207 cancer cases were recorded from 96 hospitals under the NCRP. Of these, 6.10,084 cases were included for analysis, based on the completeness and quality of the data.
The report was prepared by the Indian Council of Medical Research – National Center for Disease Informatics and Research, Bengaluru.
According to the report, head and neck cancers accounted for nearly a third (31.2 percent) of cancers in men. Gynecological cancers, including breast cancer (51 percent), accounted for more than half of all cancers in women.
The relative proportion of site-specific cancers was higher in men than in women, except for thyroid cancer (2.5 percent in women versus 1 percent in men) and gallbladder cancer (3.7 percent in women versus 2.2 percent in men).
The highest cancer rate of all sites was reported in the age group 45 to 64 years, except prostate cancer, which was higher in those over 65. More than 90 percent of cancers in various organ locations were diagnosed by microscopic examination, the report said.
Of all cancers, the highest rate of distant metastasis at presentation was seen in patients with lung cancer (49.2 percent men and 55.5 percent women), followed by gallbladder cancer (40.9 percent men and 45.7 percent women) and prostate cancer. cancer (42.9 percent).
More than a third of patients with cancers of the tongue, larynx, thyroid, corpus uteri, kidney (including children), bladder, and retinoblastoma had localized disease at the time of presentation.
Chemotherapy was the most typical method of treatment for many cancers, regardless of the clinical extent of the disease at presentation, including cancers of the liver, gallbladder, stomach, lung and childhood, the report said.
Regardless of organ site and clinical extent, most cancer patients were initiated on cancer-targeted therapy within 8 to 30 days of diagnosis.
More than half of brain and nervous system cancer patients and approximately one third of lung, prostate, bladder and thyroid cancer patients with localized disease diagnosed at the reporting facility were started on a same day cancer-targeted treatment, the report stated.
The report is based on seven-year cancer data from 96 HBCRs from hospital-based cancer registries under the NCRP. The data covers all diagnosed and treated patients of confirmed malignancies reported to these centers across the country.
Cancer surveillance is an essential part of cancer prevention and control efforts. The Indian Council of Medical Research (ICMR) started the National Cancer Registry Program (NCRP) in 1981 through a network of population and hospital-based cancer registries (PBCRs and HBCRs).
Cancer registries systematically collect, store, analyze, interpret and generate meaningful data about cancer, helping to develop plans and implement effective evidence-based strategies. (with PTI inputs)
