Possibility of using superoxide dismutase and glutathione peroxidase as endometriosis biomarkers

Objective To study the possibility of using superoxide dismutase (SOD) and glutathione peroxidase (GPx) as combined preoperative biomarkers for endometriosis. Participants and methods Female patients aged between 18 and 45 years old who came to the Gynecology outpatient clinic, Thammasat University Hospital, during September 2013–2016 with the complaint of gynecologic symptoms suspected of endometriosis, and who were positively diagnosed with endometriosis, were included in this study. All patients underwent conservative laparoscopic ovarian cystectomy with histopathological report. The control group consisted of healthy females of reproductive age who came to the outpatient clinic. The plasma SOD and GPx were measured from blood samples with commercial kits. A receiver operating characteristic curve was generated for plasma activity of SOD, GPx, and combined tests. The cutoff values were selected at the most appropriate sensitivity and specificity. Result All 36 cases were included in this study. Mean ages of patients in the patient and control groups were 33.1 and 28.6 years old, respectively. SOD and GPx activities of disease and control group were 6.15 and 8.11, 463.9 and 472.34 nmole/min/mL unit, respectively. The sensitivity and 1–specificity of the combined test were calculated at 0.78, with sensitivity, specificity, accuracy, positive predictive value, and negative predictive value being 68.75, 80.77, 76.50, 69.23, and 80.33, respectively. Conclusion A combination testing of SOD and GPx can possibly be used as preoperative biomarker for endometriosis.

Quality of Life in Cervical Cancer Survivors and Healthy Women: Thai Urban Population Study

Background : To determine a baseline quality of life (QoL) in cervical cancer survivors compared to that of healthy subjects in the tertiary Thammasat University Hospital, Thailand. Materials and Methods: The investigation was conducted at the outpatient gynecological department of Thammasat University Hospital between January and June 2016. A total of 192 women were entered into the study (97 cervical cancer survivors; 37 after radical hysterectomy (RH), 43 with concurrent chemoradiation (CRT), and 17 featuring both RH and CRT; and 95 control subjects from the same outpatient department with no history of malignancy). Participant QoL was assessed using a Thai version of the EORTC-QLQ-C30 (European Organization for Research Treatment of Cancer Quality-of-Life) and a general survey for the assessment of sociodemographic data was also conducted. Results: There were significant differences in physical, role, emotional and social functions between cervical cancer survivor and control groups. Global health, fatigue, pain, appetite loss, and financial difficulties also demonstrated statistically significant variation. Cervical cancer survivors treated by RH had higher scores for emotional and social function and global health than the control group. Moreover, they had less appetite loss, fatigue and financial difficulties. However, patients treated with CRT experienced more pain than the control group. All cervical cancer survivors had lower physical function scores than the control group. Conclusion: Quality of life in cervical cancer survivors is better than in healthy peers in some domains. Cervical cancer survivors treated with RH may have a better QoL than healthy peers. Early detection for early stage cervical cancer remains most important because treatment in early stages does not cause lowering of the QoL.
