cervical cancer is the fourth most frequent cancer in women worldwide and in Brazil, it occupies the third position for the triennium 2020/2022, with a high mortality rate and maintained in the last 10 years. It is associated with persistent human papillomavirus (HPV) infection. Primary prevention can be accomplished through vaccines that prevent HPV infection of the epithelial cells of the cervix. Secondary prevention in screening for precursor lesions through periodic repeat cervical sampling in a population of asymptomatic women. Women with abnormal cytology are more likely to have pre-invasive or invasive lesions and are referred for further testing, colposcopy. Colposcopy identifies suspicious areas and guides the best site for biopsy. In the situation of negative colposcopy and abnormal cytology, suspicion for high-grade lesion (HSIL). It recommends further investigation of the endocervical canal before the possible excisional procedure and obtaining an additional canal sample by brushing or curettage. However, to date, there is no consensus and studies lack consistent results on which is the best method for further investigation of the endocervix. Objectives: To compare the performance of additional strategies in the investigation and detection of precursor or invasive lesions in the endocervical canal in women with abnormal cytology (ASC H+) and with initial colposcopy without suspicious images.
