A Novel Metric to Guide Cancer Priorities in Pakistan

Pakistan faces an escalating cancer burden, with approximately 185,748 new cases and 118,631 deaths annually. According to GLOBOCAN data, breast cancer (16.5%), lip/oral cavity cancer (8.6%), and lung cancer (5.1%) are the most prevalent, with breast cancer alone accounting for 31.3% of female cases. The country's limited healthcare resources, including severe shortages of oncologists and radiotherapy facilities, exacerbate this crisis, requiring urgent intervention. The delta Mortality-to-Incidence Ratio (dMIR) metric identifies cancers with the largest outcome gaps between Pakistan and top-performing countries, highlighting where improvements could yield the greatest impact. For instance, stomach cancer (dMIR = 0.60), Kaposi sarcoma (0.58), and oral cavity cancer (0.49) represent critical priorities. By focusing resources on high-dMIR cancers through early detection, treatment access, and prevention programs, Pakistan can significantly reduce preventable mortality. To address these challenges, Pakistan must implement a comprehensive National Cancer Control Plan. Key steps include expanding screening programs for breast, cervical, and oral cancers; training healthcare workers; upgrading radiotherapy infrastructure; and launching public awareness campaigns targeting tobacco use and lifestyle risks. Strategic investments in these areas, coupled with policy reforms and public-private partnerships, could transform cancer outcomes in Pakistan.
