A importância do teste de captura hibrida 2 no acompanhamento de pacientes tratadas por lesão intraeptelial cervical de auto grau

Cancer of the cervix is the second most common type of cancer in women in our midst. The Human Papilloma Virus (HPV) is the main cause of cervical carcinogenesis. Squamous cell carcinoma is the most common type of cervical cancer and is preceded by precancerous lesions, known as low-grade squamous intraepithelial lesion (LSIL) or CIN 1 and high-grade squamous intraepithelial lesion (HSIL) or CIN 2 and 3. HPV detection and IELs is done through colposcopy, cytology, histopathology and molecular biology. The HSIL are those that can progress to cancer more quickly, so your diagnosis, treatment and follow-up are of great importance. The recommended treatment is Loop Electrosurgical excisional procedure (LEEP). Objective: To evaluate the importance of testing Hybrid Capture 2 (CH2), which is a molecular hybridization used in many centers to detect oncogenic HPV DNA in cases of change in squamous cells of undetermined significance (ASC-US) and more recently, monitoring of treated HSIL. Methodology: A total of 44 records of patients undergoing this treatment at a referral center for Cervical Pathology in the city of Salvador - Bahia, which had the result of colposcopy, cytological, histopathological and CH2 pre-and post-treatment, as well as the Histopathological examination of the surgical specimens. We analyzed the correlation of the results of diagnostic histopathology with parts of LEEP before and after the procedure to evaluate the accuracy of each method in detecting HSIL and its possible recurrence. Results: The sensitivity for detecting residual lesions in patients whose pieces CAF margins were free of CH2 was 52.38%, 33.33% of colposcopy and cytology 28.57%. Conclusion CH2 was the most sensitive method to detect HSIL in both the tracking and the monitoring of patients treated by CAF, followed by colposcopy and cytology.
