Acceptability of Self-Sampling HPV Testing Among Thai Women for Cervical Cancer Screening Self sampling;HPV testing;acceptability;secondary prevention;pap smear;cervical cancer; Background: Acceptability of self-sampling HPV testing is confirmed worldwide. However, some cultural differences may affect this question. Therefore, this study was conducted to evaluate the acceptability of self-sampling HPV testing in Thai women. Materials and Methods: One hundred women aged 30-65 years with an intact cervix were included in this study. The participants were asked to do the Pap test by physicians and then brush type self-sampling instruments were assigned for self-collection and finally completed a questionnaire for acceptability evaluation. The questionnaire contains 2 parts. Part one covered general information of the participants and part two is the acceptability questions. Results: Mean age was 40.6 years. The incidence of high risk HPV detection in this study was 16%. The most common reason for doing Pap smear was for annual checkup. On the topic of ease of use, 85 % of the subjects agreed. Most of the participants (82%) reported that they felt less pain. However, reliability of the result was not satisfactory because 37% of the participants hesitated to rely on the results of the test. According to the price, if the price is less than 1,000 Baht (32.59 Baht = 1USD), 82% of the subjects would use it for their next screening. Conclusions: The acceptability of self-sampling device in this study is quite good but the reliability of the test was questioned by some of the participants. Moreover, the price of the test in Thailand may also influence the acceptability of the test.

Characteristics and Treatment Outcomes of Patients with Malignant Transformation Arising from Mature Cystic Teratoma of the Ovary: Experience at a Single Institution Malignant transformation;mature cystic teratoma;dermoid;characteristics;outcome; Background: Malignant transformation arising in mature cystic teratoma (MCT) is one of the most serious complications of MCT. Squamous cell carcinoma is the most common malignant change. Some clinical findings such as advanced age group and large tumor size are significant risk factors of malignant transformation. This study was conducted in order to evaluate characteristics, cell types, treatment and outcome of malignant transformation arising from dermoid cysts in our institution. Materials and Methods: A retrospective chart review was performed. General characteristics, operative data, procedure, operative finding and operative outcome were analyzed. Statistical assessment was performed with SPSS version 17.0, using mean, mode, median and percentage to describe those data. Results: During the 10 years period, 11 cases of malignant transformation from a total of 753 cases (1.46% incidence) of MCT were reviewed. Mean age of the patients was 41.2 years (SD 4.34, range 24-70). The most common presenting symptom was a palpable mass (8 cases; 72.7%). Primary surgical staging was performed in 4 patients (36.4%). Re-staging was conducted in the other 4. Complete cytoreduction was obtained in 45.5% (5 cases) and optimal surgical resection was obtained in 36.4% (4 cases). Mean tumor size was 14.1 cm. (SD 1.55, range 6-20). Squamous cell carcinoma was found in 36.4% (4 cases) and mucinous cancer in the other 4. More than half of them were stage Ia (54.5%, 6 cases). All patients whose stage more than Ia received chemotherapy (45.5%). Mean disease free survival was 5.53 years (1.32, 0.3-10). Conclusion: According to our study, the incidence of malignant transformation was consistent with previous studies. The common malignant transformation histologic types are both squamous and mucinous carcinoma which differed from previous reports. Early detection for early stage disease and optimal surgery are important for long term survival.

To correlate the detection rate of high risk HPV (HR-HPV) DNA between self-collected and clinician-collected testing. A cross-sectional analytic study was conducted in 400 women undergoing cervical cancer screening program during February and May 2015. The procedure began with self-collected method and then clinician-collected method. Then, the specimens were processed and interpreted with the same technique. If the results from either methods were positive for HPV genotype 16 or 18, colposcopy was performed. We also conducted cytology testing for the participants. If the results were abnormal (ASC-US+), colposcopy was also performed. The detection rate of HR-HPV DNA was 10.0% and 7.5% by self-collected and clinician-collected specimen, respectively (kappa = 0.73). HR-HPV positive rate in cytology ASC-US+ was no significantly different between groups. HR-HPV DNAs were positive in every HSIL (100% detection rate). HPV DNA test positive for detection CIN+ was not significantly different between self-collected and clinician-collected testing. self-collected HPV testing can be used as an alternative option for primary cervical screening program. Detection rate of high grade lesion is similar to clinician-collected test.

Primary objective is to identify risk factors of endometriotic-cyst associated ovarian cancer (EAOC). Secondary objective is to evaluate the clinical characteristics of EAOC patients. A retrospective case-control study was conducted by analyzing data of patients from 1999 to 2014. Cases were endometriotic-cyst associated ovarian cancer with pathologically confirmed diagnosis. Controls were randomly selected with year-matched patients with benign ovarian endometriotic cyst. Univariate and multivariate with logistic regression analyses were used to identify patients' characteristics that were risk factors for endometriotic-cyst associated ovarian cancer. Altogether, 158 controls and 79 EAOC cases were recruited. Mean age of the EAOC group was 13 years older than that of the control group (49 vs. 36 years). The most common stage of EAOC was stage I (59.74%). Clear cell subtype is the most commonly found in this population (60.76%). Univariate analysis showed that age ≥42 years, menopause, weight loss, cyst diameter ≥8.33 cm, presence of solid area, bilaterality and CA 125 higher than 117.6 units/ml were significant. Multivariate analysis showed that patients with age ≥42 years (OR 7.69, 95%CI: 2.47, 23.87), menopause (OR 33.19, 95%CI: 2.37, 465.12), weight loss (OR 11.94, 95%CI: 1.52, 94.08), cyst diameter ≥ 8.3 cm (OR 10.56, 95%CI: 4.39, 25.35) and presence of solid area by ultrasonography (OR 6.70, 95%CI: 2.19, 22.35) were significant risk factors for EAOC. Advanced age, menopause, weight loss, cyst diameter ≥ 8.33 cm and presence of solid area from ultrasonography were important risk factors for EAOC.

Objectives. To evaluate the diagnostic performance among CA-125, RMI, HE4, and ROMA for cancer detection in women with nonfunctional ovarian cysts at King Chulalongkorn Memorial Hospital (KCMH). Secondary objective is to reconsider the proper cutoff value of HE4. Methods. This is a prospective analytic study in women with nonfunctional ovarian cysts larger than 3 cm who scheduled for surgery at KCMH during 3^rd June 2015 to 31^st May 2016. Ultrasonogram and blood sample collection were completed before the operation. Patients’ demographic information and pathologic results were obtained. SPSS software version 17 was used for statistical evaluation. Results. A total of 281 participants were evaluated. 19.9% of them were malignant. Compared with CA-125, HE4 had lower sensitivity (53.4% vs. 87.9%) and NPV (89% vs. 93.6%) but higher specificity (97.8% vs. 46.2%) and PPV (86.1% vs. 29.8%). ROMA had slightly lower sensitivity (79.3% vs. 87.9%) and similar NPV (93.7% vs. 93.6%), but higher specificity (79.8% vs. 46.2%) and PPV (50.5% vs. 29.8%) compared with CA-125. The model that achieves the highest area under the ROC curve in differentiating benign versus malignant ovarian tumor was ROMA. Cutoff value of HE4 at 70 pMol/L (from 150 pMol/L) would give sensitivity 74.1% and specificity 86.5% that are comparable with ROMA. Conclusions. HE4 and ROMA had better performance (higher specificity, PPV) compared to CA-125 and RMI. HE4 at 70 pMol/L could be the new cutoff value for Thai women with ovarian cysts, giving higher sensitivity and specificity.
