Researchers should no longer delay implementation of Pap screening in low and middle income countries pending research into novel screening approaches

Abstract

A study coordinated by Groesbeck Parham and Mark Schiffman describes a novel approach to single-visit, point-of-care cervical screening and triage for low and middle income countries (LMICs) that uses an HPV screening test that is not affordable in LMICs combined with a triage test that is not available at the point of care. Pap smears are feasible, affordable, and well-suited for single-visit, point-of-care cervical screening and triage in LMICs. Research into a discredited cervical screening test, funded by the US National Cancer Institute, contributed to at least 500,000 preventable cervical cancer deaths by delaying implementation of Pap screening throughout India for 18 years. Researchers should no longer delay implementation of Pap screening in LMICs pending research into novel screening approaches. Instead, researchers should prioritize cervical screening approaches that will save as many lives as quickly as possible in LMICs. To that end, Parham et al. should implement good-quality, single-visit, point-of-care Pap smear screening in LMICs until better-quality, single-visit, point-of-care HPV screening becomes widely affordable in LMICs.
