In 21,740 patients from the Department of Health's Rizal Cancer Registry, waiting more than 90 days from diagnosis to treatment was linked to a higher risk of death within five years, most clearly in breast and cervical cancer and in cancer that had not spread.
A retrospective cohort of 21,740 patients diagnosed with common cancers between 2000 and 2017 in the Department of Health Rizal Cancer Registry, followed for deaths to 2022. Treatment delay was grouped as under 30, 30 to 90 or over 90 days, and Poisson regression with robust variance estimated the risk of death from any cause within five years, by cancer type and stage.
Shortening the time from diagnosis to first treatment matters most for cancers that can still be cured, which is the case the Philippines' 2019 cancer law makes for patient navigation and referral pathways.
