Item Low-grade endometrial stromal sarcoma: A Turkish uterine sarcoma group study analyzing prognostic factors and disease outcomes(2021) Ayhan, Ali; Toptas, Tayfun; Oz, Murat; Vardar, Mehmet Ali; Kayikcioglu, Fulya; Ozgul, Nejat; Gokcu, Mehmet; Simsek, Tayup; Tunc, Mehmet; Meydanli, Mehmet Mutlu; 0000-0002-8646-0619; 33375988; AAA-6962-2022Objective. To investigate factors associated with refractory disease, recurrence, or death as well as disease-free survival (DFS) and overall survival (OS) in low-grade endometrial sarcoma (LGESS). Methods. A multi-institutional, retrospective study was conducted in a total of 124 patients, who received a curative-intent surgery. The exclusion criteria were as follows: i) history of any other invasive disease; ii) neoadjuvant therapy; iii) fertility sparing surgery; iv) a different diagnosis after review of the slides. Results. All patients underwent hysterectomy, 96% had bilateral salpingo-oophorectomy, and 65% had lymphadenectomy. Twelve (14.8%) of 81 patients undergoing lymphadenectomy had lymph node (LN) metastasis. Of those, 8 (9.8%) had pelvic LN metastasis whereas 4 (5.6% ) had isolated paraaortic LN metastasis. Six of 8 (75%) patients with positive pelvic LNs had concurrent paraaortic LN metastasis. Among 124 patients, 3 patients (2.4%) had refractory disease following primary therapy. During a median follow-up of 45.5 months, 27 (22.3%) of 121 patients who achieved complete remission after primary therapy developed recurrence, and 10 patients (8.1%) died of disease. The 3-year DFS and OS were 76.9% and 93.8%, respectively. Stage was the sole independent prognostic factor in the whole cohort. When analyzing factors within subgroups of stage I and stage >= II, there was no significant prognostic factor for stage I; however, lymphadenectomy and adjuvant chemotherapy were significantly associated with disease outcomes for stage >= II. While lymphadenectomy was related with improved DFS, chemotherapy was associated with poor DFS and OS. Conclusion. The risk of LN metastasis at pelvic as well as paraaortic lymphatic basins is not negligible to omit lymphadenectomy in stage >= II LGESS. Moreover, lymphadenectomy provides significant DFS advantage in patients with extrauterine disease. (C) 2020 Elsevier Inc.

Materials and methods The medical reports of patients undergoing at least total hysterectomy and salpingo-oophorectomy for G3-EEC between 1996 and 2018 at 11 gynecological oncology centers were analyzed. Optimal surgery was defined as removal of all disease except for residual nodules with a maximum diameter <= 1 cm, as determined at completion of the primary operation. Adequate systematic lymphadenectomy was defined as the removal of at least 15 pelvic and at least 5 paraaortic LNs. Results The study population consists of 465 women with G3-EEC. The 5-year disease-free survival (DFS) and overall survival (OS) rates of the entire cohort are 50.3% and 57.6%, respectively. Adequate systematic lymphadenectomy was achieved in 429 (92.2%) patients. Optimal surgery was achieved in 135 (75.0%) patients in advanced stage. Inadequate lymphadenectomy (DFS; HR 3.4, 95% CI 3.0-5.6; P = 0.016-OS; HR 3.2, 95% CI 1.6-6.5; P = 0.019) was independent prognostic factors for 5-year DFS and OS. Conclusion Inadequate lymphadenectomy and LVSI were independent prognostic factors for worse DFS and OS in women with stage I-II G3-EEC. Adequate lymphadenectomy and optimal surgery were independent prognostic factors for better DFS and OS in women with stage III-IV G3-EEC.Item Prognostic factors and survival outcomes of women with uterine leiomyosarcoma: A Turkish Uterine Sarcoma Group Study-003(2021) Ayhan, Ali; Celik, Husnu; Tunc, Mehmet; Kuscu, Esra; Akilli, Huseyin; 0000-0002-5240-8441; 0000-0002-8646-0619; 33685725; AAX-3230-2020; AAA-6962-2022To assess the clinicopathological features, prognostic factors, and survival rates associated with uterine leiomyosarcoma (uLMS). Databases from 15 participating gynecological oncology centers in Turkey were searched retrospectively for women who had been treated for stage I-IV uLMS between 1996 and 2018. Of 302 consecutive women with uLMS, there were 234 patients with Federation of Gynecology and Obstetrics (FIGO) stage I disease and 68 with FIGO stage II-IV disease. All patients underwent total hysterectomy. Lymphadenectomy was performed in 161 (54.5%) cases. A total of 195 patients received adjuvant treatment. The 5-year disease-free survival (DFS) and overall survival (OS) rates were 42% and 54%, respectively. Presence of lymphovascular space invasion (LVSI), higher degree of nuclear atypia, and absence of lymphadenectomy were negatively correlated with DFS, while LVSI, mitotic count, higher degree of nuclear atypia, FIGO stage II-IV disease, and suboptimal surgery significantly decreased OS. LVSI and higher degree of nuclear atypia appear to be prognostic indicators for uLMS. Lymphadenectomy seems to have a significant effect on DFS but not on OS. (c) 2021 Elsevier Inc.
