OBJECTIVE: To analyze the efficacy and prognosis of fertility-sparing therapy of the patient with complex atypical hyperplasia (CAH) and endometrial cancer (EC). METHODS: Clinical data of 191 EC and CAH patients who received fertility-sparing therapy in Peking University People's Hospital between January 2009 and September 2021 were recruited retrospectively. Outcomes of remission, recurrence and pregnancy were analyzed. RESULTS: (1) Efficacy and efficacy-related factors: The complete response (CR) rate was 86.1% (161/187) for all the patients, and the CR rate of the CAH patients were higher than that of the EC patients (92.7% vs. 79.1%, P=0.007), the CR rate was significant higher in the CAH patients (OR=2.786, P=0.035). (2) The recurrence rate was 19.3% (31/161), and the recurrence rate of the EC patients were much higher than that of the CAH patients (26.4% vs. 13.5%, P=0.039). The median recurrence time was 22.5 (9.0, 50.0) months. (3) The high risk factors of recurrence were pathological type of EC (χ²=4.880, P=0.027), without the use of metfor-min (χ²=7.075, P=0.008), longer time to complete remission (>7 months) (χ²=6.204, P=0.013), and no pregnancy (χ²=6.765, P=0.009). (4) Results of pregnancy and related factors: Among the patients who achieved CR, 108 patients had fertility willing with the pregnancy rate of 41.7% (45/108), and the live birth rate was 34.3% (37/108). The live birth rate was lower in EC than that in the CAH patients (28.6% vs. 42.4%, P=0.045). The median time to achieve pregnancy was 10.50 (5.75, 33.25) months. The pregnancy rate was significant higher in the patients with pregnancy history (OR=9.468, P < 0.001) and in those who received assisted reproductive therapy (OR=7.809, P < 0.001). CONCLUSION Fertility-sparing therapy of CAH and EC patients is effective resulting in high disease remission and certain pregnancy. However, the high recurrence rate and low pregnancy rate are still key problems for EC and CAH patients, therefore close monitoring and follow-up are indicated.

PURPOSE: The aim of the study was to determine steroid sulfatase (STS) expression in endometrial cancer patients and its correlation with disease prognosis. MATERIALS AND METHODS: We conducted a retrospective study in 59 patients who underwent surgery with histologically confirmed endometrial cancer from January 2000 to December 2011 at Hanyang University Hospital. Immuno-histochemical staining of STS was performed using rabbit polyclonal anti-STS antibody. RESULTS: Sixteen of the 59 patients (27.1%) were positive for STS expression. Disease free survival (DFS) was 129.83±8.67 [95% confidence interval (CI): 112.84-146.82] months in the STS positive group (group A) and 111.06±7.17 (95% CI: 97.01-125.10) months in the STS negative group (group B) (p=0.92). Overall survival (OS) was 129.01±9.38 (95% CI: 110.63-147.38) months and 111.16±7.10 (95% CI: 97.24-125.07) months for the groups A and B, respectively (p=0.45). Univariate analysis revealed that FIGO stage and adjuvant therapy are significantly associated with DFS and OS. However, in multivariate analysis, FIGO stage and adjuvant therapy did not show any statistical significance with DFS and OS. STS was also not significantly associated with DFS and OS in univariate and multivariate analysis. CONCLUSION: STS expression was not significantly associated with DFS and OS, despite positive STS expression in 27% of endometrial cancer patients. Therefore, the role of STS as a prognostic factor in patients with endometrial cancer remains unclear and requires further research.

OBJECTIVE: Uterine carcinosarcoma (UCS) shared the same staging system with endometrial carcinoma in the International Federation of Gynecology and Obstetrics 2009. The aim of the present study was to compare the clinicopathological and prognostic characteristics between UCS and grade 3 endometrioid endometrial carcinoma (G3EC). METHODS: A retrospective analysis of 60 UCS and 115 G3EC patients with initial treatment at the Department of Gynecology in the Fudan University Shanghai Cancer Center between February 2006 and August 2013. Chi-square analysis was used to compare differences between variables. Prognostic factors were determined using univariate/multivariate analysis, and the survival rates were assessed using the Kaplan-Meier method. The Cox regression model was used to assess the independent prognostic factor. RESULTS: UCS had significantly worse overall survival (OS) compared with G3EC. Carcinosarcoma subtype was an independent factor (hazard ratio [HR], 2.4; 95% confidence interval [CI], 1.0 to 5.8; p=0.039), stratified based on stage. Compared with G3EC, UCS patients had a greater incidence of ascites fluid (55.0% vs. 15.7%, p<0.001) and adnexal involvement (20.0% vs. 8.7%, p=0.048) and larger median tumor volume (4.6 cm vs. 4.0 cm, p=0.046). Subgroup analysis of the prognostic factors revealed that UCS patients exhibited worse OS than G3EC patients in such specific subgroups as patients at younger ages, with postmenopausal status, without ascites fluid, with early stage diseases, without vagina invasion, without lymph node metastases and receiving adjuvant chemo/radiotherapy. Adjuvant radiotherapy with chemotherapy was predictive of better survival in UCS patients compared with chemotherapy or radiotherapy alone (5-year OS, 71.0% vs. 35.8%, p=0.028). Multivariate Cox regression revealed that tumor mesenchymal component (HR, 4.6; 95% CI, 1.4 to 15.8; p=0.014) was an independent prognostic factor for UCS, whereas advanced stages (HR, 5.9; 95% CI, 1.0 to 33.9; p=0.046) and ascites fluid (HR, 5.1; 95% CI, 1.1 to 22.7; p=0.032) were independently correlated with poor prognosis for G3EC patients. CONCLUSION: The distinctions in both clinicopathological and prognostic characteristics between UCS and G3EC suggest that this subtype should be treated separately from high-risk epithelial endometrial carcinoma.

To study the effect of total matrines and extracts from Periplaneta americana on negative endometrial cancer cell JEC of progesterone receptors. After detecting the effect of total matrine, extracts from P. americana and their combination on JEC cells' growth inhibition, cell cycle, P53 and c-erbB-2 gene protein expressions through MTT, flow cytometry instrument and Western blot method, the author found that, (1) MTT: total matrines and extracts from P. americana could inhibit the growth of JEC cell, with significant increase in the inhibitory effect in the combination group. (2) Flow cytometry instrument: the cell cycle at G0/G1 increased after the treatment with total matrines, the cell cycle at G2/M increased after the treatment with extracts from periplaneta americana, and the ratio of G0/G1 cell cycle in the combination group was significantly higher than the other groups, with inhibition in cell growth and statistical difference in inter-group comparison (P < 0.05). (3) Western blot: the expression level of P53 increased and c-erbB-2 decreased after the treatment with total matrines, extracts from P. americana and their combination on JEC cell, with statistical difference in inter-group comparison (P < 0.05). The above results suggested that total matrines, extracts from P. americana and their combination could induce cell cycle arrest and inhibit the growth of JEC cell by up-regulating P53 and down-regulating the c-erbB-2 level.

OBJECTIVE: To evaluate the prevalence and features of non-endometrial cancers in Thai endometrial cancer (EC) patients. METHODS: EC patients treated in our institution were identified and the following data were collected: age, EC stage, histopathology, adjuvant therapy, other cancers, living status, and cause of death. RESULTS: The mean age of the 344 patients was 56.8+/-10.8 years. Fifty (14.5%) had other synchronous and metachronous cancers. Mean ages of the patients with or without other cancers were not significantly different, 55.7+/-10.04 years versus 57.1+/-11.0 years, respectively (p=0.358). History of any cancer in the family and tumor in the lower uterine segment were more frequent among the patients with other cancers (6.0% vs. 1.7%, p=0.095; 12.0% vs. 1.0%, p<0.001; respectively). Six patients had > or =2 other cancers. Ovarian, breast, and colon were the three most common other cancers. After a median follow-up of 57.1 months, 18.3% of patients had died: 30.0% of patients with other cancers and 16.3% of those without other cancers. The corresponding EC deaths were 14.0% and 11.2%. The 5-year overall survival was significantly lower in patients who had other cancers: 79.3% (95% confidence interval [CI], 68.3 to 90.3) vs. 86.0% (95% CI, 81.7 to 90.3) than in those without (p=0.023). However, the corresponding disease-specific survival was not significantly different: 85.1% (95% CI, 75.5 to 94.7) compared with 89.0% (95% CI, 85.1 to 92.9), respectively (p=0.514). CONCLUSION: Thai EC patients had a high incidence of other cancers. Overall survival of EC patients who had other cancers was worse than those without, while disease-specific survival was not significantly different.

OBJECTIVE: To identify current practice patterns for unresolved issues in the surgical and adjuvant management of endometrial cancer in Korea. METHODS: We designed and conducted a survey of all 218 active members of the Korean Gynecologic Oncology Group to try to identify how they would manage various case scenarios for endometrial cancer. Data were collected using an Internet survey database. RESULTS: A total of 108 members (49.5%) responded to the survey. Laparoscopy (81.6%) was the most commonly used mode of surgery in early-stage endometrial cancer. Of all the respondents, 19.8% stated that lymphadenectomy could be omitted and 21.7% recommended selective lymphadenectomy based on sentinel biopsy or frozen results for patients with presumed stage IA/grade 1 disease. On the other hand, 71.9% of respondents recommended para-aortic lymphadenectomy for patients with presumed stage IB/grade 1 disease and 86.4% recommended this treatment for presumed stage IB/grade 3 disease. The majority of respondents performed adjuvant therapy for stage IB/grade 2 (91.7%), IB/grade 3 (99.0%), and stage II (89.6%). Whole pelvic radiotherapy and vaginal brachytherapy were the most frequently used options among these patients. All respondents administered adjuvant therapy when node metastasis was found, and concurrent chemoradiotherapy (53.2%) was the most preferred option for stage IIIC1 disease. CONCLUSION: There is broad variation in both the surgical and adjuvant treatment of endometrial cancer among Korean gynecologic oncologists.

OBJECTIVE: To investigate the rate, predictors of lymph node metastasis (LNM) and pattern of recurrence in clinically early stage endometrial cancer (EC) with positive lymphovascular space invasion (LVSI). METHODS: Women with clinically early stage EC and positive LVSI 2005 to 2012 were identified. Kaplan-Meier curves and logistic regression models were used. RESULTS: One hundred forty-eight women were identified. Of them, 25.7% had LNM (21.7% pelvic LNM, 18.5% para-aortic LNM). Among patients with LNM who had both pelvic and para-aortic lymphadenectomy, isolated pelvic, para-aortic and both LNM were noted in 51.4%, 17.1%, and 31.4% respectively. Age and depth of myometrial invasion were significant predictors of LNM in LVSI positive EC. Node positive patients had high recurrence rate (47% vs. 11.8%, p<0.05) especially distant (60.9% vs. 7.9%, p<0.001) and para-aortic (13.2% vs. 1.8%, p=0.017) recurrences compared to node negative EC. LNM was associated with lower progression-free survival (p=0.002) but not overall survival (p=0.73). CONCLUSION: EC with positive LVSI is associated with high risk of LNM. LNM is associated with high recurrence rate especially distant and para-aortic recurrences. Adjuvant treatments should target prevention of recurrences in these areas.

OBJECTIVE: Recent investigations have revealed DNA mismatch repair (MMR) gene mutations are closely related with carcinogenesis of endometrial cancer; however the impact of MMR protein expression on prognosis is not determined. Correlations between MMR-related protein expression and clinicopathological factors of endometrial cancers are analyzed in the present study. METHODS: A total of 191 endometrial cancer tissues treated between 1990 and 2007 in our hospital were enrolled. Immunoreactions for MSH2, MLH1, MSH6, and PMS2 on tissue microarray specimens and clinicopathological features were analyzed retrospectively. RESULTS: Seventy-six cases (40%) had at least one immunohistochemical alteration in MMR proteins (MMR-deficient group). There were statistically significant differences of histology, International Federation of Gynecology and Obstetrics (FIGO) stage, and histological grade between MMR-deficient group and the other cases (MMR-retained group). Response rate of first-line chemotherapy in evaluable cases was slightly higher in MMR-deficient cases (67% vs. 44%, p=0.34). MMR-deficient cases had significantly better progression-free and overall survival (OS) compared with MMR-retained cases. Multivariate analysis revealed MMR status was an independent prognostic factor for OS in endometrial cancers. CONCLUSION: MMR-related proteins expression was identified as an independent prognostic factor for OS, suggesting that MMR was a key biomarker for further investigations of endometrial cancers.

OBJECTIVE: The purpose of this study is to validate the Gynecologic Oncology Group (GOG) criteria for adjuvant treatment in a different cohort of patients and to evaluate the simplified risk criteria predicting the prognosis and tailoring adjuvant treatment in patients with surgically staged endometrial cancer. METHODS: We performed a retrospective analysis of 261 consecutive patients with surgically staged endometrial cancer between January 2000 and February 2013. All patients had complete staging procedures and were surgically staged according to the 2009 International Federation of Gynecology and Obstetrics staging system. Clinical and pathologic data were obtained from medical records. We designed the simplified risk criteria for adjuvant treatment according to the risk factors associated with survival. The patients were divided into low and low-intermediate, high-intermediate, and high-risk groups according to the GOG criteria and simplified criteria and their survivals were compared. Receiver-operating characteristic curve analysis was used to evaluate the prognostic significance of both criteria. RESULTS: Median follow-up time was 48 months (range, 10 to 122 months). According to the GOG criteria, we identified 197 low and low-intermediate risk patients, 20 high-intermediate risk patients, and 44 high-risk patients. There were significant differences in disease-free (p<0.001) and overall survival (p<0.001) among the three groups. Using the simplified risk criteria, we identified 189 low and low-intermediate risk patients, 28 high-intermediate risk patients, and 44 high-risk patients. There were significant differences in disease-free (p<0.001) and overall survival (p<0.001) among the three groups. The performance of the simplified criteria (area under the curve [AUC]=0.829 and 0.916 for disease recurrences and deaths, respectively) was as good as the GOG criteria (AUC=0.836 and 0.921 for disease recurrences and deaths, respectively). CONCLUSION: The simplified criteria may be easily applicable and offer useful information for planning strategy of adjuvant treatment in patients with surgically staged endometrial cancer as the GOG criteria.

In 2014, 9 topics were selected as major advances in clinical research for gynecologic oncology: 2 each in cervical and corpus cancer, 4 in ovarian cancer, and 1 in breast cancer. For cervical cancer, several therapeutic agents showed viable antitumor clinical response in recurrent and metastatic disease: bevacizumab, cediranib, and immunotherapies including human papillomavirus (HPV)-tumor infiltrating lymphocytes and Z-100. The HPV test received FDA approval as the primary screening tool of cervical cancer in women aged 25 and older, based on the results of the ATHENA trial, which suggested that the HPV test was a more sensitive and efficient strategy for cervical cancer screening than methods based solely on cytology. For corpus cancers, results of a phase III Gynecologic Oncology Group (GOG) 249 study of early-stage endometrial cancer with high-intermediate risk factors are followed by the controversial topic of uterine power morcellation in minimally invasive gynecologic surgery. Promising results of phase II studies regarding the effectiveness of olaparib in various ovarian cancer settings are summarized. After a brief review of results from a phase III study on pazopanib maintenance therapy in advanced ovarian cancer, 2 outstanding 2014 ASCO presentations cover the topic of using molecular subtypes in predicting response to bevacizumab. A review of the use of opportunistic bilateral salpingectomy as an ovarian cancer preventive strategy in the general population is presented. Two remarkable studies that discussed the effectiveness of adjuvant ovarian suppression in premenopausal early breast cancer have been selected as the last topics covered in this review.
