Objective: The reasons why endometriosis is more aggressive and invasive in some patients are unknown. Despite the importance of population-based clinically defined risk factors in the prediction of recurrence, biochemical markers obtained from the patient are more valuable for prediction on an individual basis. Therefore, the discovery of significant potential biomarkers could be useful to clinicians for shedding light on the pathogenesis of endometriosis and in the monitoring recurrence. Materials and Methods:This study included 50 patients who underwent surgery for ovarian cysts that were diagnosed as endometrioma. The age of the patients, stage of the endometriosis, diameter and localization of endometriomas, type of surgery, and pre-and postoperative cancer antigen 125 (CA125) levels were compared between patients with and without recurrence. The archived pathology slides were stained with Ki-67 and anti-urocortin antibodies for reevaluation. By comparing the pathology parameters of the patients with and without recurrence, the association between these parameters and recurrence was investigated.Results: The median Ki-67 proliferation index of the patients with recurrence (7.5±6.5) was statistically significant compared with that of the patients without recurrence (1±4) (p=0.003). The urocortin epithelial staining intensity and percentage were not found to be statistically significant in comparison. A statistically significant difference was determined between postoperative CA125 median levels of patients without recurrence (10±17.6) and those of patients with recurrence (29.9±18.1) (p=0.003). Conclusion:The Ki-67 proliferation index may be useful for predicting prognosis and recurrence risk.Keywords: Endometriosis, Ki-67 proliferation index, urocortin ÖZ Amaç: Endometriozisin bazı hastalarda neden daha agresif ve invaziv olduğunun nedenleri bilinmemektedir. Klinik olarak belirlenen risk faktörleri populasyon bazında rekürrens prediksiyonunda değerli olmasına rağmen kişi bazında prediksiyonda hastadan elde edilen biyokimyasal markerlar daha değerlidir. Bu nedenle, rekürrens açısından anlamlı potansiyel biyomarkerların keşfi endomeriozis patogenezine ışık tutabileceği gibi rekürrens takibinde klinisyenlere yardımcı bir parametre olarak kullanılabilir.Gereç ve Yöntem: Çalışmamıza over kisti nedeniyle cerrahi geçiren ve patolojik inceleme sonucunda endometrioma tanısı konmuş 50 hasta dahil edildi. Olguların yaş, endometriozis evresi, endometrioma çapı ve lokalizasyonu, cerrahi tipi, preoperatif ve postoperatif CA 125 düzeyleri kaydedildi. Olguların arşiv patoloji preparatları Ki 67 ve anti-urocortin antikor ile boyandı. Patolojik parametreler nüks olan olgular ile olmayanlarda kıyaslanarak bu parametrelerin rekürrens ile ilişkisi araştırıldı.Bulgular: Nüks olan olguların Ki67 İndeks medyanı (7,5±6,5) nüks olmayan olguların Ki67 İndeks medyan değerinden (1±4) daha büyük olup, istatistiksel olarak anlamlıydı (p=0,003). Olguların nüks olma durumu ile ürocortin epitel boyanma yoğunluğu ve yüzdesine göre da...

Background Cervical cancer screening algorithms are increasingly focused on Human Papillomavirus (HPV)‐based screening while the accuracy of using abnormal cytological findings to detect dysplastic lesions still remains important. This retrospective study correlated the results of conventional cervical cytology, colposcopy guided biopsy, and cold knife conization (CKC) procedures performed in a tertiary center. Materials and Methods Data from 9399 patients who underwent screening with conventional cervical cytology between 2010 and 2019 was obtained from the hospital registry. Abnormal cervical cytology and high‐risk HPV DNA genotypes were recorded and their colposcopic and CKC pathology was determined. Results Two hundred and ninety two patients underwent colposcopy for abnormal cervical cytology and/or high‐risk HPV positivity. One hundred and twenty three patients were positive for High‐risk HPV. Abnormal cervical cytology was detected in 216 patients. The most common cytological anomaly was atypical squamous cells of undetermined significance (ASCUS) found in 9399 patients (1.39%). It was determined that conventional cytology had a sensitivity of 70.8% and a specificity of 62.2% for the detection of low‐grade lesions, while it had a sensitivity of 72.4% and a specificity of 86.0% for the detection of high‐grade lesions. CKC was applied to 68 patients who were diagnosed with high‐grade squamous intraepithelial lesions (HSIL) as a result of the colposcopy. As a result of CKC, a high‐grade lesion was detected in 73.5% of these patients. Conclusion Conventional cervical cytology and colposcopy exhibited higher accuracy as the severity of lesions increased. Detection of HPV may prevent unnecessary surgical procedures, especially with ASCUS.
