Objective:To determine predictors of having cervical intraepithelial neoplasia (CIN) 1 or less in loop electrosurgical excision procedure (LEEP) specimens of patients with colposcopic directed biopsy-confirmed CIN 2-3. Methods: Two hundred and eighty patients with colposcopic directed biopsy-confirmed CIN 2-3 who subsequently underwent LEEP were enrolled in the retrospective study. Related clinical data were collected to determine the predictors of CIN 1 or less in LEEP specimens. Results: CIN 1 or less in LEEP specimens was found in 71 (25.4%) of 280 patients. Multivariate logistic regression analyses demonstrated that nulliparity [OR (95% CI) = 3.375 (1.245-9.150)], low grade Papanicolaou (Pap) results [OR (95% CI) = 6.410 (2.877-14.280)] and low grade colposcopic impression [OR (95% CI) = 16.506 (5.844-46.632)] were significant risk factors of having CIN 1 or less in LEEP specimens. Neither persistent nor recurrent CIN 2-3 was detected in 71 patients who had CIN 1 or less in LEEP specimens. However, persistent or recurrent CIN 2-3 developed in 3 out of 209 (1.4%) patients with CIN 2-3 found in LEEP specimens. Conclusion: Approximately 25% of patients with CIN 2-3 in colposcopic directed biopsy specimens had CIN 1 or less found in LEEP specimens. Predicting factors of having CIN 1 or less in LEEP specimens were nulliparity, low grade Pap results and low grade colposcopic impression.

Objective: To evaluate predictive factors between serum inflammatory markers and malignancy potential of endometrium. Methods: This retrospective study was conducted at the gynecological oncology unit, department of obstetrics and gynecology, at the faculty of medicine of Thammasat University. The study period was from 2017 to 2020. Endometrial cancer and benign gynecologic disease cases who underwent hysterectomy (with or without adnexectomy) during the study period were recruited. Demographic characteristics, histopathology reports and serum markers were also collected. Results: The study included a study group of 49 participants with endometrial cancer and a control group consisting of 119 cases of benign uterine disease. The study group had statistically significantly higher mean ages, proportional menopausal status and instances of underlying diseases when compared with the control group. Neutrophil/Lymphocyte ratios (NLR) and Platelet/Lymphocyte ratios (PLR) could not meaningfully predict the malignant potential of endometrium in hysterectomy specimens. NLR and PLR were statistically associated with depth of myometrial invasion (MI) in endometrial cancer cases. NLR equal to or greater than 1.93 predicted MI more than half thickness with sensitivity, specificity, accuracy, positive (PPV) and negative predictive value (NPV) at a percentage of 83.3, 52.8, 37.0, 90.5 and 60.4, respectively. PLR equal to or greater than 134.95 predicted MI of greater than fifty percent thickness with sensitivity, specificity, accuracy, PPV and NPV at 75.0, 55.6, 36.0, 87.0 and 60.4 percent, respectively. Conclusion: NLR and PLR have positive associations with myometrial invasion of endometrial cancer.

Objective:The colposcopic vision guided loop electrosurgical excisional procedure (LEEP) was studied for the effective diagnosis of cervical cancer and cervical intraepithelial neoplasia (CIN). Methods: A total of 199 patients participated in this study. Individual cases were from gynecologic outpatients at Thammasat University Hospital, Thailand. These had diagnoses for CIN and were selected for treatment with colposcopic guided LEEP. The average age of patients in this study was 45. Menopausal women represented 31%, (61/199) of the patients. The most frequently found Pap smear result among these women (44%, 88/199), was that of high-grade squamous intraepithelial lesion. The next most frequent Pap smear result (32%, 64/199) was low-grade squamous intraepithelial lesion. Patients' medical records and outcomes were evaluated for consistency of pathological examination between colposcopic directed biopsy and LEEP. Discrepancies between initial diagnosis and the final diagnosis were also analyzed. Results: The colposcopic guided LEEP accurately determined 100% of the cervical cancer cases and 84.8 % of the high-grade squamous intraepithelial lesion cases. Involvement of the ectocervical or endocervical margin regions was found to be 5% and 10% respectively, in this study. Excessive bleeding complication, either during the excision and/or postoperative recovery was found in 3% and 6% of cases, respectively. Conclusion: LEEP under colposcopic vision is a recommended technique for ambulatory management of precancerous lesion and early diagnosis of cervical cancer. This technique significantly reduces rate of positive ectocervical cone margin involvement.
