    (2019) Sahin, Hanifi; Meydanli, Mehmet Mutlu; Sari, Mustafa Erkan; Kocaman, Eda; Cuylan, Zeliha Fırat; Yalcin, Ibrahim; Coban, Gonca; Ozen, Ozlem; Sirvan, Levent; Gungor, Tayfun; Ayhan, Ali; 30638487
    Objective: The purpose of this study was to determine the patterns of failure and prognostic factors for lymphovascular space invasion (LVSI)-positive endometrioid endometrial cancer (EC) patients in the setting of negative lymph nodes (LNs). Materials and methods: A multicenter, retrospective department database review was performed to identify LVSI-positive patients with disease surgically confined to the uterus at two gynecologic oncology centers in Turkey. Demographic, clinicopathological and survival data were collected. Results: We identified 185 LVSI-positive women with negative LNs during the study period. Fifty-five (29.7%) were classified as Stage IA, 94 (50.8%) as Stage IB, and 36 (19.5%) as Stage II. The median age at diagnosis was 59 years and the median duration of follow-up was 44 months. The total number of the recurrences was 12 (6.5%). We observed 5 (2.9%) loco-regional recurrences, 3 (1.5%) retroperitoneal failures, and 4 (2.0%) distant relapses. The 5-year progression-free survival (PFS) was 86.1% while the 5-year overall survival (OS) rate was 87.7%. Grade 3 histology (Hazard Ratio [HR] 2.9, 95% Confidence Interval [CI] 1.02-8.50; p = 0.04), cervical stromal invasion (HR 4.5, 95% CI 1.61-12.79; p = 0.004) and age > 60 years (HR 5.8, 95% CI 1.62-21.32; p = 0.007) were found to be independent prognostic factors for decreased OS. Adjuvant treatment did not appear as a prognostic factor for OS even in univariate analysis. Conclusion: The recurrence rate among LVSI-positive endometrioid EC patients is low in the setting of negative LNs. However, one out of three patients with a recurrence experiences distant relapses which usually portend worse outcomes. (C) 2018 Taiwan Association of Obstetrics & Gynecology.

    Uterine smooth muscle tumor of uncertain malignant potential: fertility and clinical outcomes
    (2019) Sahin, Hanifi; Karatas, Funda; Coban, Gonca; Ozen, Ozlem; Erdem, Ozlem; Onan, Mehmet Anil; Ayhan, Ali; 0000-0002-3285-5519; 31074239
    Objective: In this study, we aimed to evaluate the clinicopathological features, obstetric, and oncological outcomes of patients diagnosed with a uterine smooth muscle tumors of uncertain malignant potential (STUMP). Methods: A dual-institutional, database review was carried out to screen patients with STUMP who were treated with upfront surgery between January 2006 and December 2017. Data including age at the time of diagnosis, recurrence rate, disease-free survival, overall survival, and fertility outcomes were retrospectively analyzed. Results: Fifty-seven patients with STUMPs were included in the study. The median age at the time of diagnosis was 42 (range, 16 to 75) years. The median follow-up was 57 (range, 16 to 125) months. Eight patients (14%) had recurrence during follow-up. Recurrent STUMPs were seen in seven patients and leiomyosarcoma after 14 months in one patient. Seven patients with a recurrent STUMP survived, while the remaining patient died. Recurrence rates were similar for women who underwent myomectomy and those who underwent hysterectomy. The presence of uterine localization of tumor (subserosal vs intramural-submucosal) statistically significantly affected recurrence rates (odds ratio=5.72; 95% confidence interval=1.349-24.290; p=0.018). Ten of 27 patients who underwent myomectomy for uterine myoma had fertility desire. Seven pregnancies were recorded. Conclusions: Our study results suggest that fertility-sparing approaches are feasible in patients with STUMP, although recurrence may be seen.

    Outcome of sacrospinous ligament fixation with conventional instruments in the treatment of Stage 3-4 vaginal vault prolapse
    (2019) Sahin, Hanifi; Yalcin, Ibrahim; Sahin, Eda Adeviye; Sari, Mustafa Erkan; Ayhan, Ali
    Purpose: The objective of this study was to investigate the effectiveness of the sacrospinous ligament fixation (SSLF) at 12 months following the operation. Materials and Methods: This retrospective study included patients diagnosed with vaginal vault prolapse and underwent SSLF between January 2014 and May 2017. The subjective evaluation was performed according to the Patient Global Impression of Improvement (PGI-I). The objective success rate at the end of 12 months was evaluated, and the Pelvic Organ Prolapse-Quantification System (POP-Q) Stage 0 or 1 was considered as a successful outcome. The effectiveness of the operation and the complication rates were evaluated during one-year follow-up. Results: A total of 26 patients were included in the study. Twelve patients (46.2%) underwent unilateral SSLF and 14 patients (53.8%) bilateral SSLF operation. At 12 months, the objective and subjective success rates were 100% and 100%, respectively. There was a significant difference between the unilateral and bilateral SSLF groups in terms of the operation time and intraoperative bleeding. After one-year follow-up, only three patients (11.3%) complained about mild gluteal pain. Conclusion: The suspension of the vagina to the unilateral or bilateral sacrospinous ligament was an effective and safe surgical method in patients with post-hysterectomy vaginal vault prolapse.

    Prognostic factors and treatment outcomes in surgically-staged non-invasive uterine clear cell carcinoma: a Turkish Gynecologic Oncology Group study
    (2017) Sari, Mustafa Erkan; Meydanli, Mehmet Mutlu; Turkmen, Osman; Comert, Gunsu Kimyon; Turan, Ahmet Taner; Karalok, Alper; Sahin, Hanifi; Kocaman, Eda; Akbayir, Ozgur; 0000-0002-1741-7035; 28541637
    Objective: To assess the prognosis of surgically-staged non-invasive uterine clear cell carcinoma (UCCC), and to determine the role of adjuvant therapy. Methods: A multicenter, retrospective department database review was performed to identify patients with UCCC who underwent surgical treatment between 1997 and 2016 at 8 Gynecologic Oncology Centers. Demographic, clinicopathological, and survival data were collected. Results: A total of 232 women with UCCC were identified. Of these, 53 (22.8%) had surgically-staged non-invasive UCCC. Twelve patients (22.6%) were upstaged at surgical assessment, including a 5.6% rate of lymphatic dissemination (3/53). Of those, 1 had stage IIIA, 1 had stage IIIC1, 1 had stage IIIC2, and 9 had stage IVB disease. Of the 9 women with stage IVB disease, 5 had isolated omental involvement indicating omentum as the most common metastatic site. UCCC limited only to the endometrium with no extra-uterine disease was confirmed in 41 women (73.3%) after surgical staging. Of those, 13 women (32%) were observed without adjuvant treatment whereas 28 patients (68%) underwent adjuvant therapy. The 5-year disease-free survival rates for patients with and without adjuvant treatment were 100.0% vs. 74.1%, respectively (p=0.060). Conclusion: Extra-uterine disease may occur in the absence of myometrial invasion (MMI), therefore comprehensive surgical staging including omentectomy should be the standard of care for women with UCCC regardless of the depth of MMI. Larger cohorts are needed in order to clarify the necessity of adjuvant treatment for women with UCCC truly confined to the endometrium.

    Comparison of three different risk-stratification models for predicting lymph node involvement in endometrioid endometrial cancer clinically confined to the uterus
    (2017) Haberal, Ali; Kocaman, Eda; Dursun, Polat; Ayhan, Ali; Korkmaz, Vakkas; Meydanli, Mehmet Mutlu; Yalcin, Ibrahim; Sari, Mustafa Erkan; Sahin, Hanifi; Gungor, Tayfun; 0000-0002-1741-7035; 0000-0002-1486-7209; 0000-0002-7869-9662; 29027396; AAI-9331-2021; AAJ-5802-2021
    Objective: To compare the clinical validity of the Gynecologic Oncology Group-99 (GOG-99), the Mayo-modified and the European Society for Medical Oncology (ESMO)-modified criteria for predicting lymph node (LN) involvement in women with endometrioid endometrial cancer (EC) clinically confined to the uterus. Methods: A total of 625 consecutive women who underwent comprehensive surgical staging for endometrioid EC clinically confined to the uterus were divided into low- and high-risk groups according to the GOG-99, the Mayo-modified, and the ESMO-modified criteria. Lymphovascular space invasion is the cornerstone of risk stratification according to the ESMO-modified criteria. These 3 risk stratification models were compared in terms of predicting LN positivity. Results: Systematic LN dissection was achieved in all patients included in the study. LN involvement was detected in 70 (11.2%) patients. LN involvement was correctly estimated in 51 of 70 LN-positive patients according to the GOG-99 criteria (positive likelihood ratio [LR+], 3.3; negative likelihood ratio [LR-], 0.4), 64 of 70 LN-positive patients according to the ESMO-modified criteria (LR+, 2.5; LR-, 0.13) and 69 of the 70 LN-positive patients according to the Mayo-modified criteria (LR+, 2.2; LR-, 0.03). The area under curve of the Mayo-modified, the GOG-99 and the ESMO-modified criteria was 0.763, 0.753, and 0.780, respectively. Conclusion: The ESMO-modified classification seems to be the risk-stratification model that most accurately predicts LN involvement in endometrioid EC clinically confined to the uterus. However, the Mayo-modified classification may be an alternative model to achieve a precise balance between the desire to prevent over-treatment and the ability to diagnose LN involvement.

    Does the primary route of spread have a prognostic significance in stage III non-serous epithelial ovarian cancer?
    (2018) Coban, Gonca; Sahin, Hanifi; Meydanli, Mehmet Mutlu; Sari, Mustafa Erkan; Yalcin, Ibrahim; Ozkan, Nazli Topfedaisi; Cuylan, Zeliha Firat; Erdem, Baki; Gungorduk, Kemal; Akbayir, Ozgur; Dede, Murat; Salman, Mustafa Coskun; Gungor, Tayfun; Ayhan, Ali; 0000-0002-3285-5519; 29506569; AAI-9974-2021
    Background: The purpose of this retrospective study was to determine the prognosis of non-serous epithelial ovarian cancer (EOC) patients with exclusively retroperitoneal lymph node (LN) metastases, and to compare the prognosis of these women to that of patients who had abdominal peritoneal involvement. Methods: A multicenter, retrospective department database review was performed to identify patients with stage III non-serous EOC at 7 gynecologic oncology centers in Turkey. Demographic, clinicopathological and survival data were collected. The patients were divided into three groups based on the initial sites of disease: 1) the retroperitoneal (RP) group included patients who had positive pelvic and / or para-aortic LNs only. 2) The intraperitoneal (IP) group included patients with > 2 cm IP dissemination outside of the pelvis. These patients all had a negative LN status, 3) The IP / RP group included patients with > 2 cm IP dissemination outside of the pelvis as well as positive LN status. Survival data were compared with regard to the groups. Results: We identified 179 women with stage III non-serous EOC who were treated at 7 participating centers during the study period. The median age of the patients was 53 years, and the median duration of follow-up was 39 months. There were 35 (19.6%) patients in the RP group, 72 (40.2%) in the IP group and 72 (40.2%) in the IP/RP group. The 5-year disease-free survival (DFS) rates for the RP, the IP, and IP/ RP groups were 66.4%, 37.6%, and 25.5%, respectively (p = 0.002). The 5-year overall survival (OS) rate for the RP group was significantly longer when compared to those of the IP, and the IP/RP groups (74.4% vs. 54%, and 36%, respectively; p = 0.011). However, we were not able to define "RP only disease" as an independent prognostic factor for increased DFS or OS. Conclusions: Primary non-serous EOC patients with node-positive-only disease seem to have better survival when compared to those with extra-pelvic peritoneal involvement.

    Comparison of stage III mucinous and serous ovarian cancer: a case-control study
    (2018) Ayhan, Ali; Cuylan, Zeliha Fırat; Karabuk, Emine; Oz, Murat; Turan, Ahmet Taner; Meydanli, Mehmet M.; Taskin, Salih; Sari, Mustafa Erkan; Sahin, Hanifi; Ulukent, Suat C.; Akbayir, Ozgur; Gungorduk, Kemal; Gungor, Tayfun; Kose, Mehmet F.; 30376858
    Background: The purpose of this case-control study was to compare the prognoses of women with stage III mucinous ovarian carcinoma (MOC) who received maximal or optimal cytoreduction followed by paclitaxel plus carboplatin chemotherapy to those of women with stage III serous epithelial ovarian cancer (EOC) treated in the similar manner. Methods: We performed a multicenter, retrospective review to identify patients with stage III MOC at seven gynecologic oncology departments in Turkey. Eighty-one women with MOC were included. Each case was matched to two women with stage III serous EOC in terms of age, tumor grade, substage of disease, and extent of residual disease. Survival estimates were measured using Kaplan-Meier plots. Variables predictive of outcome were analyzed using Cox regression models. Results: With a median follow-up of 54months, the median progression-free survival (PFS) for women with stage III MOC was 18.0months (95% CI; 13.8-22.1, SE: 2.13) compared to 29.0 months (95% CI; 24.04-33.95, SE: 2.52) in the serous group (p = 0.19). The 5-year overall survival rate of the MOC group was significantly lower than that of the serous EOC group (44.9% vs. 66.3%, respectively; p < 0.001). For the entire cohort, presence of multiple peritoneal implants (Hazard ratio [HR] 2.39; 95% confidence interval [CI], 1.38-4.14, p = 0.002) and mucinous histology (HR 2.28; 95% CI, 1.53-3.40, p < 0.001) were identified as independent predictors of decreased OS. Conclusion: Patients with MOC seem to be 2.3 times more likely to die of their tumors when compared to women with serous EOC.

    Impact of lymph node ratio on survival in stage III ovarian high-grade serous cancer: a Turkish Gynecologic Oncology Group study
    (2018) Ayhan, Ali; Ozkan, Nazli Topfedaisi; Sari, Mustafa Erkan; Celik, Husnu; Dede, Murat; Akbayir, Ozgur; Gungorduk, Kemal; Sahin, Hanifi; Haberal, Ali; Gungor, Tayfun; Arvas, Macit; Meydanli, Mehmet Mutlu; 29185270
    Objective: The purpose of this study was to investigate the prognostic value of lymph node ratio (LNR) in patients with stage III ovarian high-grade serous carcinoma (HGSC). Methods: A multicenter, retrospective department database review was performed to identify patients with ovarian HGSC at 6 gynecologic oncology centers in Turkey. A total of 229 node-positive women with stage III ovarian HGSC who had undergone maximal or optimal cytoreductive surgery plus systematic lymphadenectomy followed by paclitaxel plus carboplatin combination chemotherapy were included. LNR, defined as the percentage of positive lymph nodes (LNs) to total nodes recovered, was stratified into 3 groups: LNR1 (<10%), LNR2 (10%<= LNR<50%), and LNR3 (>= 50%). Kaplan-Meier method was used to generate survival data. Factors predictive of outcome were analyzed using Cox proportional hazards models. Results: Thirty-one women (13.6%) were classified as stage IIIA1, 15 (6.6%) as stage IIIB, and 183 (79.9%) as stage IIIC. The median age at diagnosis was 56 (range, 18-87), and the median duration of follow-up was 36 months (range, 1-120 months). For the entire cohort, the 5-year overall survival (OS) was 52.8%. An increased LNR was associated with a decrease in 5-year OS from 65.1% for LNR1, 42.5% for LNR2, and 25.6% for LNR3, respectively (p<0.001). In multivariate analysis, women with LNR >= 0.50 were 2.7 times more likely to die of their tumors (hazard ratio [HR]= 2.7; 95% confidence interval [CI]= 1.42-5.18; p<0.001). Conclusion: LNR seems to be an independent prognostic factor for decreased OS in stage III ovarian HGSC patients.

    Impact of lymph node ratio on survival in stage IIIC endometrioid endometrial cancer: a Turkish Gynecologic Oncology Group study
    (2018) Ayhan, Ali; Ozkan, Nazli Topfedaisi; Oz, Murat; Comert, Gunsu Kimyon; Cuylan, Zeliha Fırat; Coban, Gonca; Turkmen, Osman; Erdem, Baki; Sahin, Hanifi; Akbayir, Ozgur; Dede, Murat; Turan, Ahmet Taner; Celik, Husnu; Gungor, Tayfun; Haberal, Ali; Arvas, Macit; Meydanli, Mehmet Mutlu; 29770619
    Objective: The purpose of this study was to investigate the prognostic value of lymph node ratio (LNR) in women with stage IIIC endometrioid endometrial cancer (EC). Methods: A multicenter, retrospective department database review was performed to identify patients with stage IIIC pure endometrioid EC at 6 gynecologic oncology centers in Turkey. A total of 207 women were included. LNR, defined as the percentage of positive lymph nodes (LNs) to total nodes recovered, was stratified into 2 groups: LNR1 (<= 0.15), and LNR2 (> 0.15). Kaplan-Meier method was used to generate survival data. Factors predictive of outcome were analyzed using Cox proportional hazards models. Results: One hundred and one (48.8%) were classified as stage IIIC1 and 106 (51.2%) as stage IIIC2. The median age at diagnosis was 58 (range, 30-82) and the median duration of follow-up was 40 months (range, 1-228 months). There were 167 (80.7%) women with LNR <= 0.15, and 40 (19.3%) women with LNR > 0.15. The 5-year progression-free survival (PFS) rates for LNR <= 0.15 and LNR > 0.15 were 76.1%, and 58.5%, respectively (p= 0.045). An increased LNR was associated with a decrease in 5-year overall survival (OS) from 87.0% for LNR <= 0.15 to 62.3% for LNR > 0.15 (p= 0.005). LNR > 0.15 was found to be an independent prognostic factor for both PFS (hazard ratio [HR]= 2.05; 95% confidence interval [CI]= 1.07-3.93; p= 0.03) and OS (HR= 3.35; 95% CI= 1.57-7.19; p= 0.002). Conclusion: LNR seems to be an independent prognostic factor for decreased PFS and OS in stage IIIC pure endometrioid EC.
