Background: Despite the fact that ovarian cancer is the seventh most common cancer in women worldwide and the fifth leading cause of cancer death, It is the most common cause of death due to reproductive cancers in Thailand where epithelial ovarian cancer (EOC) is commonly found. According to a Thai statistical analysis in 2010 by the Department of Medical Services, epithelial ovarian cancer was the sixth most common cancer in Thailand from 2001to 2003.The incidence of 5.1 per 100,000 women per year. Human epididymis protein 4 (HE4) is a novo diagnostic tumor marker for EOC. The combination of HE4 and carcinoma antigen 125 (CA 125) is a tool for detecting epithelial ovarian cancer (EOC) better than using CA 125 alone. Therefore, the researcher is interested in HE4 does have a role to predict recurrent epithelial ovarian cancer. Materials and Methods: The patients who had complete response after diagnosed with epithelial ovarian cancer by pathology, FIGO stage 3 or more had been treated through surgery and chemotherapy at the Sunpasitthiprasong Hospital from June 2014 until March 2016. The patients were followed up every three months, using tumor marker (CA 125, HE4,Carcinoma antigen 19-9) together with other checkup methods, such as rectovaginal examination, CXR every year and other imaging as indication. Afterwards, the data was analyzed for the ability of HE4 to detect recurrence of epithelial ovarian cancer. Results: In 47 patients in this study follow-up for 22 months after complete response treatment from surgery and chemotherapy in epithelial ovarian cancer, 23 had recurrent disease and HE4 titer rising. The patients with recurrent epithelial ovarian cancer demonstrated high levels of both HE4 and CA125 with sensitivity of 91.3% and 52.7% respectively, specificity of 87.5% and 95.6% and positive predictive values of 87.5% and 85.7%. HE4 can predict recurrent epithelial ovarian cancer (p-value=0.02242). Comparing HE4 and CA125 in predicting recurrent epithelial ovarian cancer HE4 had more potential than CA125 (p-value =0.8314). Conclusions: The present study showed HE4 to have a role in predicting recurrent epithelial ovarian cancer and HE4 is potentially better than CA125 as a marker for this purpose.

Background: The aim of this study was to explore the efficacy and adverse reactions of CT-guided radioactive 125I-seed implantation treatment combined with chemotherapy for platinum-resistant recurrent ovarian carcinoma. Materials and Methods: From September 2010 to December 2012, 23 patients with platinum-resistant recurrent ovarian carcinoma were enrolled. All the patients refused, could not bear, or were not suitable for surgery. They all had no more than 3 lesions, which were detected and could also be measured by CT. All were clarified as single-lesion or multiple-lesion groups. A total of 41 lesions underwent implantation of from 8 to 106 125I seeds (median=43). Multi-plane implanting was adopted and 125I-seeds of (0.4-0.7)mCi were placed at intervals of (0.5-1.0) cm. After implantation treatment, all patients underwent 4 cycles of chemotherapy with gemcitabine $800mg/m^2$ (days 1, 8 and 15). Results: The outcome was evaluated with CT 3 weeks and every 3 months after implantation treatment. After 6 months, the volume of 32 out of 41 lesions (78.0%) was reduced at least 30%, within which 9 lesions completely disappeared(22.0%). Complete response was observed in 7 cases (30.4%), with a partial response in 4 cases (17.4%), 4 cases stable(17.4%)and 8 cases showing progression (34.8%). The total clinical remission rate was 47.8% (11/23). The clinical remission rate was 77.8% (7/9) in the single-lesion group and 28.6% (4/14) in the multiple-lesion group with a significant difference between the two(P=0.036). The common side effects observed were mild gastrointestinal reactions. Conclusions: 125I-seed implantation combined with chemotherapy applies an effective way in the treatment of platinum-resistant recurrent ovarian epithelial carcinoma with the advantages of high local control rates, good short-term effects, little trauma and less side effects.

Background: To study the response rate, toxicity profiles, and survival of refractory or recurrent epithelial ovarian cancer (EOC) patients treated with paclitaxel. Materials and Methods: Patients with refractory or recurrent EOC who were treated with paclitaxel between January 2002 and December 2011 at the Department of Obstetrics and Gynecology, Faculty of Medicine, Vajira Hospital were identified. Clinicopathological features of the patients including detailed data of paclitaxel treatment were collected. Results: During the study period, a total of 44 patients were identified, with a mean age of $52.9{\pm}8.2$ years. Some 13.6% (six patients) had refractory cancer to first-line chemotherapy while 86.4% (38 patients) had recurrent cancer. Among these, 35 (79.6%) and 9 (20.4%) patients were considered as platinum-sensitive and platinum-resistant, respectively. Three patients (6.8%) received fewer than 2 cycles of paclitaxel due to loss to follow-up, leaving 41 patients evaluable for response. The overall response rate observed in all 41 patients was 41.5% (17 patients; 12 complete and five partial responses): 12.5% or 1/8 patients with refractory or platinum-resistant cancer and 48.5% or 16/33 patients with platinum-sensitive disease. Stable disease was demonstrated in 17.0% (seven patients) while progressive disease was apparent in 41.5% (17 patients). Median time to progress was 4.5 months (range, 0.67-58.6 months). Median progression-free survival was not reached while median overall survival was 16.3 months (95% confidence interval, 11.0 months -21.6 months). Common toxicities were neutropenia, neuropathy, and alopecia. Conclusions: Paclitaxel is an active agent for refractory or recurrent EOC. Neutropenia, neuropathy and alopecia are common side effects.
