- Aim: To compare the clinical performance of human papillomavirus (HPV) mRNA and DNA assays in postmenopausal women. Materials and Methods: A total of 5,925 postmenopausal women were tested with cytology and the Luminex HPV DNA assay. High risk-HPV-positive women with benign cytology underwent a complimentary HPV mRNA assay (APTIMA). Both assays and the cytological testing were repeated after 12 months. Results: A total of 334 women were found to be high-risk HPV-positive; 272 out of these women met the inclusion criteria. At follow-up, 25 (9.2%) out of the 272 included women had cytological abnormalities. HPV mRNA assay at follow-up had a sensitivity of 84% (95% confidence interval=63.9-95.4%) and a specificity of 60.2% (95% confidence interval=53.7-66.3%; p=0.0003) to detect these lesions. Corresponding values for the HPV DNA assay were 88% (95% confidence interval=68.8-97.4%) and 43.5% (95% confidence interval=37.2-49.4%). Conclusion: The HPV mRNA assay offers a comparable sensitivity but a higher specificity than the HPV DNA assay in detecting precancerous cervical lesions.

- Background/Aim: To compare human papillomavirus (HPV) DNA detection in self-collected vaginal and urine samples with clinician-taken cervical samples in relation to histology. Materials and Methods: Self-collected vaginal, urine and clinician-taken cervical samples were analyzed from 218 women with the Cobas 4800 HPV test (Roche Molecular Diagnostics). Results: The sensitivity for detection of HPV in the vaginal self-sampling test was 96.4% and in urine was 83.9% relative to detection by clinician-taken cervical sample. The vaginal self-sampling and the clinician-taken HPV tests had the same sensitivity of 92.8% (95% confidence interval=86.3-96.8%) and specificity for detection of high-grade squamous intraepithelial lesion (HSIL) and adenocarcinoma in situ (AIS). Detection in urine samples had a sensitivity of 76.3% (95% confidence interval=67.9-84.2%) for HSIL/AIS. Conclusion: The Cobas 4800 HPV test detects high-grade pre-cancerous cervical lesions in self-collected vaginal samples with the same high sensitivity as in clinician-taken cervical samples.

- BACKGROUND/AIM: Inflammation is a hallmark of cancer, and the role of neutrophils and neutrophil extracellular traps (NETs) in cancer and cancer-associated thrombosis has attracted a lot of interest. The NET-specific marker H3Cit has been found to be elevated in the plasma of patients with malignancies, suggesting NETs markers as novel cancer biomarkers. This study aimed to determine the levels of NETs markers (H3Cit and dsDNA) in the plasma of women with adnexal masses. PATIENTS AND METHODS: Peripheral blood samples were obtained from 199 patients admitted for primary surgery of adnexal masses. Patients were grouped according to tumor type and stage. Plasma levels of H3Cit-DNA, dsDNA, and CA125 were quantified. RESULTS: Plasma levels of H3Cit-DNA and dsDNA were not elevated in women with borderline or malignant ovarian tumors compared with those of the benign group. Increased levels of CA125 were found in the borderline and ovarian cancer group (ptrend<0.001). In Cox regression analysis, CA125 levels dichotomized at 326 IU/ml (median) were associated with worse overall survival (HR=1.9; 95%CI=1.03-3.36; p=0.038). No differences were found in the survival analyses of malignant ovarian tumors by analyzing the dsDNA and H3Cit-DNA levels. CONCLUSION: There is no association between NETs markers and ovarian tumors.

- BACKGROUND/AIM: Cervical cancer is associated with poorer diagnosis among the elderly and pap-smear screening has a lower sensitivity. Self-sampling for detection of high-risk human papillomavirus (hr-HPV) may be an alternative screening method. The aim of this study was to analyze the response rate to vaginal HPV self-sampling and the HPV mRNA prevalence among women 69-70 years. MATERIALS AND METHODS: An HPV self-sampling kit was sent to 1,000 women 69-70 years whom had not taken a cervical smear in ≥5 years. The samples were analyzed by the Aptima HPV mRNA assay. HPV-positive women were recalled for a follow-up examination. RESULTS: The self-sample response rate was 43.3%. The HPV mRNA prevalence was 6.2%. All HPV-positive women attended follow-up. CONCLUSION: HPV self-sampling was accepted among older women. Although the HPV mRNA prevalence was 6.2%, no high-grade cytological abnormalities were found. Larger studies are needed to elucidate hr-HPV self-sampling as a tool to identify older women at risk of cervical cancer.

- Background/Aim: To assess preoperative blood levels of a biomarker panel in relation to the new classification system of epithelial ovarian cancer (EOC) type I and II. Patients and Methods: Preoperative plasma levels of B7-family protein homolog 4 (B7-H4), intact and cleaved soluble urokinase plasminogen activator receptor (suPAR), human epididymis protein 4 (HE4) and cancer antigen 125 (CA125) were analyzed in 350 patients with adnexal lesions. Results: The levels of suPAR(II-III), HE4, CA125 were all higher in EOC II than in EOC I, borderline and benign ovarian tumors. B7-H4 was increased in EOC II compared with benign ovarian tumors. The combination of suPAR(II-III), HE4, CA125 and age in premenopausal women discriminates EOC and borderline tumors from benign tumors to higher accuracy compared to the Risk of Ovarian Malignancy Algorithm (p=0.007). Conclusion: The biomarker panel suPAR(II-III), HE4, CA125 and age in premenopausal women improved discrimination of malignant and benign ovarian tumors. The plasma levels of B7-H4 were increased in patients with EOC II compared to those with benign ovarian tumors.

- Background/Aim: To evaluate ovarian cancer surgery in tertiary centers (TC) and regional hospitals (RH). Patients and Methods: Data from the GynOp registry on patients undergoing surgery for ovarian cancer or borderline tumor from 2013 to 2015 were analyzed. Results: Four TC and 21 RH reported 1,108 cases of surgery with curative intent, 770 cases (69.5%) in TC and 338 cases (30.5%) in RH. Out of 458 patients with International Federation of Gynecology and Obstetrics (FIGO) stage IIIC-IV disease 396 (86.5%) had surgery in TC. We found differences in selection for primary debulking surgery (PDS) (45% to 93%, p<0.001) and PDS achieving no residual tumor (36% to 70%, p<0.001) between the four TC. Major complications, re-admissions and re-operation rates did not differ between TC and RH. Conclusion: Tertiary centers perform more extensive surgery compared to regional hospitals without increased frequency of major complications. Tertiary centers display significant differences among patient selection for PDS, as well as achieving no residual tumor.

- BACKGROUND/AIM: Cervical cancer is the most common cancer among women in Ethiopia. The objective was to evaluate the participation rate of a free of charge vaginal self-sample (Aptima multitest swab, Hologic) for the detection of human papillomavirus (HPV) in an Ethiopian cohort. PATIENTS AND METHODS: Specimens were collected from women employed by Ethiopian Airlines in Addis Abeba (N=5950). Samples were analysed for the presence of high-risk (HR) HPV mRNA by the Aptima HPV assay (Hologic) and HPV positive women were referred for cytology. Identification of HPV types among HPV positive samples was performed by Modified general primer-PCR and Luminex assay. RESULTS: Participation rate was 3.1% and the prevalence of HPV mRNA was 20.6% (37/180). CONCLUSION: Primary HPV mRNA screening with vaginal self-sampling may be an acceptable approach in Ethiopia. One out of five women harbor HPV in their vaginal self-sample in agreement with other similar studies from the region.
