Item Safety of Laparoscopic Surgery in the Management of Endometrioid Endometrial Cancer(2023) Durdag, Gulsen Dogan; Alemdaroglu, Songul; Simsek, Seda Yuksel; Yetkinel, Selcuk; Celik, Husnu; 36861713Background: Laparoscopic surgery has increasingly been preferred in recent years. However, data regarding the safety of laparoscopy in endometrial cancer are not sufficient. The aim of this study was to compare perioperative and oncologic outcomes of laparoscopic and laparotomic staging surgery in patients with endometrioid endometrial cancer and to evaluate the safety and efficacy of laparoscopic surgery in this population. Methods: Data of 278 patients, who underwent surgical staging for endometrioid endometrial cancer at the gynecologic oncology department of a university hospital between 2012 and 2019, were analyzed retrospectively. Demographic, histopathologic, perioperative, and oncologic characteristics were compared between laparoscopy and laparotomy groups. A subgroup of patients with a body mass index (BMI) >30 was further evaluated. Results: Demographic and histopathologic characteristics were similar between the two groups, while laparoscopic surgery was seen to be significantly superior in terms of perioperative outcomes. The number of removed and metastatic lymph nodes was significantly higher in the laparotomy group; however, this difference did not affect the oncologic outcomes, including recurrence and survival rates, and the two groups had similar results in this aspect. The outcomes of the subgroup with BMI >30 were also in accordance with the whole population. Intraoperative complications in laparoscopy were managed successfully. Conclusions: Laparoscopic surgery appears to be advantageous over laparotomy, and depending on the surgical experience, it may be performed safely for surgical staging of endometrioid endometrial cancer.Item Assessing the Quality of Life in Patients with Endometrial Cancer Treated with Adjuvant Radiotherapy(2015) Karabuga, Havva; Gultekin, Melis; Tulunay, Gokhan; Yuce, Kunter; Ayhan, Ali; Yuce, Deniz; Yildiz, Ferah; 0000-0003-0440-0725; 26207785; AAJ-5802-2021Objective The current study evaluates long-term quality of life (QOL) and sexual function of patients with endometrial cancer who received adjuvant pelvic external beam radiotherapy (EBRT) and/or vaginal brachytherapy (BRT). Materials and Methods One hundred forty-four endometrial cancer survivors who were treated between January 2000 and December 2009 in our department were included in this study. Median follow-up was 79 months (range, 31-138 months). Fifty-two patients were treated with 45 to 50.4 Gy EBRT, 76 were with BRT, and 16 were with both EBRT and BRT. Brachytherapy was in the form of vaginal cuff BRT with 5 x 550 cGy high dose rate BRT, prescribed to the first 4 cm and whole wall thickness of vagina. Quality of life was assessed using the European Organization for Research and Treatment of Cancer Quality of Life Questionnaire Core 30 and subscales from the supplemental 24-item Cervical Cancer Module. Results Vaginal BRT patients reported better physical functioning (P = 0.01), role functioning (P = 0.03), and sexual enjoyment (P = 0.01) compared to EBRT group. Symptom score (P = 0.01), lymphedema (P = 0.03), pain (P = 0.02), and diarrhea (P = 0.009) scores were also higher with EBRT. Vaginal BRT did not worsen symptom scores or sexual functions when added to EBRT. Obese patients experienced higher rates of lymphedema (P = 0.008). Cognitive and role functioning scores were significantly higher in patients with normal body mass index. Conclusions External beam radiotherapy negatively affects long-term QOL and sexual functions in endometrial cancer survivors. Vaginal BRT provides higher QOL. Patients with body mass index within normal limits have improved QOL.Item Oncofertility for Gynecologic and Non-Gynecologic Cancers: Fertility Sparing in Young Women of Reproductive Age(2014) Dursun, Polat; Dogan, N. Utku; Ayhan, Ali; 25090914; AAJ-5802-2021About ten percent of all female cancer survivors is younger than 40 years of age. For these young women the primary goal is to ensure the highest possibility of cure and to maintain the reproductive functions as well. Oncofertility is a new concept including both oncology and reproductive medicine. By this recently defined concept young women will have maximal chance to make an optimal decision without any significant impact and delay in oncologic outcome. Oncofertility concept could be applied for genital cancer as well as non-genital cancer of reproductive age. Currently sperm and embryo banking are the standard methods used for young patients with cancer whose future fertility is under risk. In contrary oocyte banking, ovarian tissue cryopreservation are all controversial procedures and still accepted as experimental by many authors although American Society of Reproductive Medicine (ASRM) consideres oocyte cryopreservation "no longer experimental". For genital cancers procedures for oncofertility depends on the type of the cancer and the treatment of choice. In this review the current data and concepts regarding oncofertility concept including the gynecologic oncologic perspective is reviewed. (C) 2014 Elsevier Ireland Ltd.

It is a tremendous report representative of great effort. Hovewer, as practicing gynecologic oncologists, endometrial carcinoma is the most common clinical entity encountered in our routine daily practice; as such, we find some of the report confusing and object to some of its findings, as detailed in this brief report. We also attempted to summarize the differences between the well-known NCCN guidelines and the ESMO-ESGO-ESTRO Consensus Conference guidelines and try to give the point of view of gynecologic oncologic perspective. It is obvious that differences in the management of endometrial carcinomas will continue to be debated by the scientific community.Item Conservative Management of Endometrial Cancer: A Survey Amongst European Clinicians(2018) La Russa, M.; Zapardiel, I.; Halaska, M. J.; Zalewski, K.; Laky, R.; Dursun, P.; Lindquist, D.; Sukhin, V.; Polterauer, S.; Biliatis, I.; 29943129To investigate differences and similarities in the clinical approach of young clinicians managing women with endometrial cancer (EC) conservatively. A web-based survey was carried out. A platform of the European Network of Young Gynaecological Oncologists (ENYGO) database was used. A 38-item multiple-choice questionnaire was used to evaluate current practice in fertility-sparing management of EC. The survey covered investigations, treatment options, follow-up and management of recurrence and future family planning. Descriptive statistics were used. Overall, 116 out of 650 (17.84%) ENYGO members responded to the survey. In 92 (79.3%) centres, the caseload of early stage EC treated conservatively was less than 10 per year. One hundred and seven responders (93.8%) believe that treatment with progestins could be offered in grade 1 EC without myometrial invasion, but a minority would recommend it even for grade 2 tumours with no myometrial invasion or grade 1 with superficial invasion. The diagnostic tool for establishing grade of tumour was hysteroscopy with dilatation and curettage in 64 (55%) centres. Medroxyprogesterone acetate represents the most commonly prescribed progestogen (55, 47.4%). In 78 (67.2%) centres, a repeat endometrial biopsy was offered after 3 months of treatment commencement. Recurrences are treated mostly with hysterectomy (81, 69.9%) with only a small number of responders recommending to repeat progestin treatment. Lynch syndrome is a contraindication for conservative management in half of the responders (57, 49.1%). Most clinicians agree that patients should be referred promptly for assisted reproductive techniques once complete response has been achieved (68, 58.6%). Our study shows that conservative management is increasingly offered to women affected by early stage EC wishing to preserve their fertility. Further studies and joint registries are required to evaluate safety and effectiveness of this approach in this probably growing number of patients.Item Is the Oncological Outcome of Early Stage Uterine Carcinosarcoma Different from That of Grade 3 Endometrioid Adenocarcinoma?(2021) Gungorduk, Kemal; Plett, Helmut; Gulseren, Varol; Meydanli, Mutlu; Boyraz, Gokhan; Ozdemir, Isa Aykut; Sahin, Hanifi; Senol, Taylan; Yildirim, Nuri; Turan, Taner; Oge, Tufan; Gokcu, Mehmet; Taskin, Salih; Ayhan, Ali; Ataseven, Beyhan; 33249415; AAJ-5802-2021Aim: The clinicopathologic characteristics, recurrence patterns, and survival of patients with grade 3 endometrial cancer (G3-EAC) and uterine carcinosarcoma (UCS) were compared. Materials and Methods: The medical records of patients treated for G3-EAC and UCS between January 1996 and December 2016 at 11 gynecologic oncology centers in Turkey and Germany were analyzed. Results: Of all patients included in the study, 161 (45.1%) were diagnosed with UCS and 196 (54.9%) with G3-EAC at FIGO stage I-II (early stage) disease. The recurrence rate was higher in patients with UCS than in those with G3-EAC (17.4 vs. 9.2%, p = 0.02). The 5-year disease-free survival (DFS; 75.2 and 80.8%, respectively; p = 0.03) and overall survival (OS; 79.4 and 83.4%, respectively; p = 0.04) rates were significantly lower in the UCS group compared to the G3-EAC group. UCS histology was an independent prognostic factor for decreased 5-year DFS (HR 1.8, 95% CI 1.2-3.2; p = 0.034) and OS (HR 2.7, 95% CI 1.3-6.9; p = 0.041) rates. Conclusions: The recurrence rate was higher in UCS patients than in G3-EAC patients, regardless of disease stage. DFS and OS were of shorter duration in UCS than in G3-EAC patients. Adequate systematic lymphadenectomy and omentectomy were an independent prognostic factor for increased 5-year DFS and OS rates.Item Accuracy of intra-operative frozen section in guiding surgical staging of endometrial cancer(2021) Dogan Durdag, Gulsen; Alemdaroglu, Songul; Aka Bolat, Filiz; Yilmaz Baran, Safak; Yuksel Simsek, Seda; Celik, Husnu; 0000-0002-5064-5267; 0000-0003-4335-6659; 0000-0001-5874-7324; 0000-0003-3191-9776; 0000-0003-1185-9227; 33608802; AAI-9594-2021; AAI-8400-2021; AAK-7016-2021Purpose Surgery consists the main treatment of endometrial cancer; however, decision of lypmhadenectomy is controversial. Intra-operative frozen section (FS) is commonly used in guiding surgical staging; nevertheless, there are different reports regarding its adequacy and reliability. Aim of this study is to assess accuracy of FS in predicting paraffin section (PS) results in patients with endometrium cancer. Methods Data of 223 cases, who were operated for endometrial cancer at a tertiary hospital in 2012-2019, were analyzed retrospectively. Histological type, grade, tumor diameter, depth of myometrial invasion, and cervical and adnexal involvement in frozen and paraffin section were evaluated. Positive and negative predictive values and accuracy of frozen results in predicting paraffin results for each parameter was assessed. Statistical significance was taken as 0.05 in all tests. Results Accuracy of FS in predicting PS results were 76.23% for histology, 75.45% for grade, 85.31% for depth of myometrial invasion, and 95.45% for tumor diameter. Surgery, based on FS results, caused undertreatment in 4 patients, while metastatic lymph node ratios were found in only 35.3-50.0% of cases who had high risk parameters at FS. Conclusion Our FS results have reasonable accuracy rates in predicting PS results, in comparison with the previous literature. However, even if the high risk parameters detected in FS predict PS accurately, absence of lymph node involvement in all cases with high risk parameters indicates that FS-based triage cannot prevent unnecessary lymphadenectomies.Item Comparison of two intraoperative examination methods for the diagnosis of sentinel lymph node metastasis in clinically early stage endometrial cancer: A Turkish Gynecologic Oncology Group Study (TRSGO-SLN-003)(2021) Taskin, Salih; Varli, Bulut; Altin, Duygu; Takmaz, Ozguc; Vatanseverc, Dogan; Ersoz, Cevriye Cansiz; Turan, Hasan; Bulutay, Pinar; Zeren, Handan; Havare, Semiha Battal; Karabuk, Emine; Naki, Murat; Gungor, Mete; Kose, Faruk; Ortac, Firat; Arvas, Macit; Ayhan, Ali; Taskiran, Cagatay; 33894621Objective: This study evaluated diagnostic accuracy of intraoperative sentinel lymph node (SLN) frozen section examination and scrape cytology as a possible solution for management of SLN positive patients. Study design: Clinically early-stage endometrial cancer patients who underwent SLN algorithm and intraoperative SLN examination were analyzed. Findings were compared with final pathology results and diagnostic accuracy of frozen section and scrape cytology were evaluated. Results: Of the 208 eligible patients, 100 patients (48 %) had frozen section examination and 108 (52 %) had scrape cytology of the SLN. Intraoperative examination and final pathology were negative for metastasis in 187/208 (90 %) cases. The rest 21 cases had metastatic SLNs according to final pathology. 12 of 21 (57 %) metastases were classified as macrometastasis. Intraoperative examination of SLNs correctly identified 13 cases (true positive) and missed 8 cases (false negative). Five of 8 false negative cases had micrometastasis or isolated tumor cells. Considering identification of macrometastasis, sensitivity and negative predictive value were 85.71 % and 98.94 %, respectively, for the frozen section and 60.00 % and 98.15 %, respectively, for the scrape cytology. Conclusion: Frozen section examination of SLN has higher sensitivity in detecting macrometastasis compared to scrape cytology and it could help the surgeon in decision for further lymphadenectomy intraoperatively.

A propensity match analysis(2020) Onal, Cem; Yuce Sari, Sezin; Akkus Yildirim, Berna; Gultekin, Melis; Guler, Ozan Cem; Yildiz, Ferah; 0000-0002-2742-9021; 0000-0001-6908-3412; 31793400; D-5195-2014; AAC-5654-2020We evaluated the survival outcomes and recurrence patterns of endometrial cancer (EC) patients with pelvic lymph node metastases who received postoperative radiotherapy (RT) to the pelvis (P-RT) or to the pelvis plus paraaortic lymph nodes (PA-RT) with or without systemic chemotherapy (ChT). The data from 167 patients with stage IIIC1 EC treated with postoperative RT or RT and ChT were collected retrospectively. Those patients with pelvic lymph node metastases were treated with either P-RT (106 patients, 63%) or PA-RT (61 patients, 37%). The median follow-up time for the entire cohort was 49 (range = 5-199) months. The patients receiving adjuvant ChT and RT had significantly higher 5-year OS rates (77% vs. 33%, p < .001) and 5-year PFS rates (71% vs. 30%, p < .001) when compared to those receiving adjuvant RT alone. The patients receiving P-RT and ChT had significantly higher 5-year OS rates and 5-year PFS rates when compared to those treated with adjuvant PA-RT in the entire cohort and matched cohort. Adjuvant ChT together with RT is the strongest predictor of the OS and PFS. Prophylactic PA-RT is unnecessary, even if ChT is used together with P-RT in EC patients with pelvic lymph node metastasis.Impact statement What is already known on this subject? Local and distant recurrence risks are relatively higher in patients with stage IIIC disease, postoperative adjuvant treatment is required to reduce the recurrence risk. Adjuvant RT is a common approach for patients with locally advanced EC. Optimal target volume for RT in patients with stage IIIC EC remains controversial. We demonstrated that extended field RT is unnecessary, even if ChT is used together with pelvic RT in stage IIIC EC patients. What do the results of this study add? We demonstrated that adjuvant ChT together with RT is the strongest predictor of the OS and PFS for EC patients with pelvic lymph node metastases. Extended field RT is unnecessary, even if ChT is used together with pelvic RT in EC patients with pelvic lymph node metastases.Item Does Polyp-Originated Growing have Prognostic Significance for Stage 1 Endometrioid-Type Endometrial Cancer?(2020) Kucukyildiz, Irem Alyazici; Gunakan, Emre; Akilli, Huseyin; Haberal, Asuman Nihan; Kuscu, Esra; Haberal, Ali; Ayhan, Ali; 0000-0002-5240-8441; 0000-0002-0992-6980; 0000-0001-9852-9911; 0000-0002-1486-7209; AAX-3230-2020; AAI-8792-2021; AAK-4587-2021; AAI-9331-2021Purpose Endometrioid-type endometrial cancer is usually diagnosed in the early stages and has a good prognosis. Patients with stage 1 disease have survival rates over 95%. Tumor factors affect survival in these patients, but polyp-originated growing has not been sufficiently discussed in the literature. This study aimed to determine the effect of polyp-originated growing in stage 1 endometrioid-type endometrial cancer and to provide a review of the literature. Methods This study includes 318 stage 1 endometrioid-type endometrial cancer patients. The patients were divided into two groups based on the tumor origin. Group I included patients with polyp-originated growing tumors, and Group II included patients with endometrial surface-originated growing tumors. Results Groups I and II included 39 and 279 patients, respectively. The general properties of the patients were similar; there were no significant differences. The univariate survival analyses showed that overall survival for Groups I and II was 65.5 and 83.6 months, respectively; this difference was statistically significant (p = 0.002). The multivariate analysis of age, maximum tumor diameter, tumor origin, lymphovascular space involvement, myometrial invasion depth and tumor grade showed that polyp-originated growing was independently and significantly associated with overall survival (HR 4.05; 95% CI 1.2-13.5; p = 0.023). Conclusion Polyp-originated growing may be a prognostic factor for early stage endometrioid-type endometrial cancer. The prognostic effect of polyp-originated growing is not well known, and further investigation is necessary.
