BACKGROUND: Cervicovaginal cytology as a follow-up study in women with a history of a cervical carcinoma treated with chemo-radiotherapy (CRT) plays an important role; however, the cytomorphological characteristics for the diagnosis of high-grade squamous intraepithelial lesions (H-SIL) in post-CRT patients have not been established. The aim of the study is to find the cytomorphological characteristics that support the diagnosis of H-SIL by conventional cytology in these patients.
MATERIALS AND METHODS: This is a cross-sectional study from 2009 to 2015, which includes patients with a diagnosis of squamous cell carcinoma treated with CRT, who all have cervix cytology for follow-up and a later biopsy.
RESULTS: We identified 82 cases, where the most frequent clinical stage was IIA1 to IIB with 26 cases (61.9%), the most common symptom was transvaginal bleeding (64.29%). The cytological characteristics that were statistically associated with the presence of a positive biopsy were the presence of a hemorrhagic background (45.2% vs. 12.5%, P = .007), high cellularity (45.2% vs. 15%, P < .001), disposition in groups/sheets (69% vs. 22.5%, P < .001), postradiotherapy changes at the background of the smear (73.8 vs. 50%, P < .001) and an increased nuclear/cytoplasmic ratio (100% vs. 22.5%, P < .001).
CONCLUSIONS: In patients with CRT, the presence of specific features can help the diagnosis of H-SIL with excellent diagnostic performance.
