Item Sinonasal inverted papilloma: Recurrence, surgical management, and mini review(2021) Olgun, LeventObjective: Sinonasal inverted papilloma (SIP) has a high rate of recurrence and a potential to be transformed into a malignant disease, hence surgery is the treatment of choice. In this study, we aimed to identify the preoperative features of patients diagnosed with SIP and discuss treatment options, recurrence rates, and postoperative clinical outcomes. Methods: Twenty-six patients who were diagnosed with SIP between 2010 and 2014 in a training and research hospital were included in the study. Their charts were reviewed retrospectively. The complaints at admission, findings of anterior rhinoscopy, nasal endoscopy, and radiological examinations were recorded along with histopathological features. Different surgical treatment modalities and recurrence rates were analyzed regarding tumor characteristics and postoperative outcome. Results: The average postoperative follow-up was 32.1 +/- 20 months. According to Krouse classification, 15 (57.7%) patients were staged as T3, eight (30.8%) were T2, and three (11.5%) were T1. Endoscopic sinus surgery was performed in 21 patients. Medial maxillectomy via lateral rhinotomy (classical technique) was performed in five patients. Two patients (7.7%) who had endoscopic surgery had a recurrence of SIP; however, the rate was not statistically significant when compared with that of patients who underwent the classical technique. Histopathological examination revealed chronic rhinosinusitis with nasal polyposis (19.2%), squamous metaplasia (3.8%), and squamous cell carcinoma (7.7%) concurrent with SIP. Conclusion: Endoscopic surgery should be the first choice for the treatment of SIP. It may be combined with classical methods in some patients with advanced stage disease, especially when the tumor spreads to areas that are difficult to reach. Following surgical intervention, the patients should be followed carefully to identify recurrence or malignant transformation as early as possible.Item Recurrence patterns and prognostic factors in lymphovascular space invasion-positive endometrioid endometrial cancer surgically confined to the uterus(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; 30638487Objective: 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.

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.Item Factors associated with survival after relapse in patients with low-risk endometrial cancer treated with surgery alone(2017) Haberal, Ali; Celik, Husnu; Coban, Gonca; Ozkan, Nazli Topfedaisi; Meydanli, Mehmet Mutlu; Sari, Mustafa Erkan; Demirkiran, Fuat; Kahramanoglu, Ilker; Bese, Tugan; Arvas, Macit; Sahim, Hanifi; Ozge, Tufan; Yalcin, Omer Tarik; Akbayir, Ozgur; Erdem, Baki; Numanoglu, Ceyhun; Ozgul, Nejat; Boyraz, Gokhan; Salman, Mehmet Coskun; Yuce, Kunter; Dede, Murat; Yenen, Mufit Cemal; Taskin, Salih; Altin, Duygu; Ortac, Ugur Firat; Ayik, Hulya Aydin; Simsek, Tayup; Gungor, Tayfun; Gungorduk, Kemal; Sanci, Muzaffer; Ayhan, Ali; 0000-0002-1486-7209; 0000-0002-3285-5519; 0000-0003-1185-9227; 28657226; AAI-9331-2021; AAJ-5802-2021; AAL-1923-2021; AAI-9974-2021Objective: To determine factors influencing overall survival following recurrence (OSFR) in women with low-risk endometrial cancer (EC) treated with surgery alone. Methods: A multicenter, retrospective department database review was performed to identify patients with recurrent "low-risk EC" (patients having less than 50% myometrial invasion [MMI] with grade 1 or 2 endometrioid EC) at 10 gynecologic oncology centers in Turkey. Demographic, clinicopathological, and survival data were collected. Results: We identified 67 patients who developed recurrence of their EC after initially being diagnosed and treated for low-risk EC. For the entire study cohort, the median time to recurrence (TTR) was 23 months (95% confidence interval [CI]=11.5-34.5; standard error [SE]=5.8) and the median OSFR was 59 months (95% CI=12.7-105.2; SE=23.5). We observed 32 (47.8%) isolated vaginal recurrences, 6 (9%) nodal failures, 19 (28.4%) peritoneal failures, and 10 (14.9%) hematogenous disseminations. Overall, 45 relapses (67.2%) were loco-regional whereas 22 (32.8%) were extrapelvic. According to the Gynecologic Oncology Group (GOG) Trial-99, 7 (10.4%) out of 67 women with recurrent low-risk EC were qualified as high-intermediate risk (HIR). The 5-year OSFR rate was significantly higher for patients with TTR >= 36 months compared to those with TTR <36 months (74.3% compared to 33%, p=0.001). On multivariate analysis for OSFR, TTR <36 months (hazard ratio [HR]=8.46; 95% CI=1.65-43.36; p=0.010) and presence of HIR criteria (HR=4.62; 95% CI=1.69-12.58; p=0.003) were significant predictors. Conclusion: Low-risk EC patients recurring earlier than 36 months and those carrying HIR criteria seem more likely to succumb to their tumors after recurrence.
