A Novel Metric to Guide Cancer Priorities in Pakistan.

Abstract

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.
