Concordance and acceptability of a novel human papillomavirus self-collection tool for cervical cancer screening in economically developed regions: a prospective cohort study in Shanghai, China

The novel self-sampling device achieves high concordance comparable to clinician-collected specimens while demonstrating superior patient acceptability. Its advantages in privacy protection, procedural comfort, and cost-effectiveness position it as a promising complementary strategy to enhance cervical cancer screening coverage, particularly among under-screened high-risk populations.
