Abstract

Objective: Many epidemiological studies have shown that human papillomavirus related infections play a major role in cervical preinvasive and invasive lesions. ASCUS (atypical cells of undetermined significance) observed in about 4-5% of all cervical cytology specimens. We searched for the presence of HPV with immunohistochemical methods in the biopsy material of patients diagnosed with ASCUS using cytology. Material and Method: The colposcopic biopsy or Loop Electro Excisional Procedure (LEEP) material of 115 patients with a diagnosis of ASCUS were evaluated. HPV (type 6,11,16,18,31,33,42,51,52,56 and 58) immunohistochemistry was applied to all materials. The relationship between the biopsy results and HPV positivity was investigated. Results: Cervical intraepithelial neoplasia (CIN) I was found in 34.8%, CIN II in 13% and CIN III in 9.6% of the patients and cervicitis was present in 42.6% of the patients. HPV immunohistochemistry was positive in 11 cases (9.6%) and no staining was seen in 104 cases (90.4%). No positive staining was seen in the chronic cervicitis cases. The rate of positive staining was 15% (6/34) in the CIN I diagnosed group, 20% (3/12) in the CIN II diagnosed group and 18.2% (2/9) in the CIN III diagnosed group. Conclusion: HPV positivity was found to be lower compared to the literature both in total and in cases diagnosed by biopsy. No staining occurred in any patient with cervicitis. In conclusion, we believe that immunohistochemical examination is not an appropriate method for the determination of HPV.

Özet

Amaç: Yapılan birçok epidemiyolojik çalışmada human papilloma virüse bağlı enfeksiyonların servikal preinvaziv ve invaziv lezyonlarda başlıca rolü oynadığı ispatlanmıştır. ASCUS (atypical cells of undetermined significance) tüm servikal sitolojilerin yaklaşık %4-5inde saptanır. Bu çalışmada sitolojide ASCUS tanısı almış ve kolposkopik biyopsi uygulanmış hastaların biyopsi materyallerinde immünohistokimyasal olarak HPV varlığı araştırıldı. Gereç ve Yöntem: 115 ASCUS tanısı alan hastanın kolposkopik biyopsi ve/veya Loop Electro Excisional Procedure (LEEP) materyalleri değerlendirildi. Tüm materyallere immünohistokimyasal olarak HPV (tip 6,11,16,18,31,33,42,51,52,56 ve 58) uygulandı. Biyopsi sonuçları ile HPV pozitifliği arasındaki ilişki araştırıldı. Bulgular: Çalışma grubundaki hastaların %34,8inde CIN (Servikal intraepitelyal neoplazi) I, %13ünde CIN II, % 9,6sında CIN III, % 42,6sında servisit saptandı. Olguların 11inde (% 9,6) HPV immünohistokimyası pozitif olup, 104ünde (% 90,4) boyanma görülmedi. Kronik servisitlerde pozitif boyanma görülmedi. CINtanılı grupta pozitif boyanma oranı %15 (6/34), CIN II tanılı grupta %20 (3/12) ve CIN III tanılı grupta %18,2 (2/9) idi. Sonuç: Çalışmamızda, HPV pozitifliği hem toplamda, hem de biyopsi ile tanımlanmış CIN olgularında literatürde verilen rakamlara göre oldukça düşüktür. Ancak servisit olgularının hiçbirinde boyanma olmamıştır. Sonuç olarak immünohistokimyasal incelemenin HPV tespitinde kullanılmasının uygun bir teknik olmadığı düşünülmüştür.
