Clinical significance of CK7, HPV-L1, and koilocytosis for patients with cervical low-grade squamous intraepithelial lesions: A retrospective analysis

Most cervical low-grade squamous intraepithelial lesions (LSILs) do not progress to high-grade squamous intraepithelial lesions (HSILs); however, reliable biomarkers that predict LSIL progression are lacking. We investigated the association of cytokeratin 7 (CK7), human papillomavirus-L1 capsid protein (HPV-L1), and koilocytosis with clinical outcomes of patients with LSIL. CK7, HPV-L1, Ki67, and p16-INK4A expression was determined in 72 cervical LSIL and 28 HSIL biopsy samples; koilocytosis was evaluated by reviewing biopsy slides.
