ABSTRACT
The question of whether Chlamydia trachomatis (Ct) is a cofactor for human Papillomavirus (HPV) in cervical carcinogenesis is still controversial. We conducted a molecular detection study of both infections in 622 Brazilian women, including 252 women with different grades of abnormal cervical cytology and cervical cancer (CC; cases) and 370 women with normal cytology (controls). Although Ct infection did not seem related to CC carcinogenicity, women with abnormal cytology had a significant high rate of Ct infection. Therefore, it is important to adopt protocols for diagnosis and treatment of this bacterium in conjunction with screening for CC in this population.

OBJECTIVE: To evaluate the strategy of "see and treat" by loop electrosurgical excision procedure (LEEP) for cytologic high-grade precancerous cervical lesions (squamous intraepithelial lesions; HSIL) and post-LEEP recurrence among low-income Brazilian women. METHODS: In a retrospective survey of women who underwent LEEP for cytologic HSIL without prior cervical biopsy between January 2004 and March 2008 at CISVALI, União da Vitória, Paraná, Brazil, LEEP sample histology and patient follow-up by Papanicolaou smear were assessed. RESULTS: Among 117 women treated, 24% had no lesions, 67.5% had cervical intraepithelial neoplasia (CIN) grade 2/3, and 5.2% had squamous cell carcinoma or adenocarcinoma on LEEP histology. Among patients with follow-up, recurrences occurred in those with no lesions (16.7%) and CIN 2/3 (25%) (P>0.05). HSIL was the most frequent type of recurrence (87%) (P<0.001). In total, 6.3% of patients had positive ectocervical (ecto-positive) and endocervical (endo-positive) margins, 3.8% had ecto-positive, and 33.0% had endo-positive margins. Recurrences occurred in women with endo-positive (26.3%), no margin (17.4%), and cautery artifact margin (25.0%) involvement (P>0.05). CONCLUSION: For cytologic HSIL, the benefits of the strategy of "see and treat" by LEEP outweighed the risk of overtreatment. Patients with both positive and negative margins on LEEP should be followed carefully.
