Item Vaginal cuff brachytherapy practice in endometrial cancer patients: a report from the Turkish Oncology Group(2021) Bolukbasi, Yasemin; Onal, Cem; Ozsaran, Zeynep; Senyurek, Sukran; Akdemir, Eyub Yasar; Selek, Ugur; Yildiz, Ferah; 33897788Purpose: The American Brachytherapy Association is attempting to develop standards for delivering brachytherapy, although differences in practice have been reported in the literature. This study evaluated vaginal cuff brachytherapy (VBT) practice and quality of life-related recommendations among Turkish radiation oncologists. Material and methods: A nationwide web-based 17-item survey was distributed to the members of the Turkish Society for Radiation Oncology. These members received e-mail notifications, and a link was posted on the Turkish Society for Radiation Oncology internet site to solicit voluntary responses The survey addressed the simulation processes, target volume, prescribed dose, delivery schedules, and recommendations related to vaginal side effects. Results: Fifty-seven radiation oncologists responded to the survey. The most used dose fraction schemes for adjuvant VBT were 7 Gy x 3 fractions (30%), 5.5 Gy x 5 fractions (26%), and 6 Gy x 5 fractions (28%). The preferred VBT scheme was 5 Gy x 3 fractions (50%) when the external beam radiotherapy (EBRT) dose was 45 Gy external radiotherapy, while the preferred schemes were 6 Gy x 3 fractions (30%) or 5 Gy x 3 fractions (32%) when the external radiotherapy dose was increased to 50.4 Gy. One-half of the respondents delivered VBT twice a week, and the dose was prescribed to 0.5 cm from vaginal mucosa by 86% of the respondents. There was no common definition for the dose prescription length, which was defined as 3 cm from the vaginal cuff in 33% of responses and as 4 cm in 35% of responses. For serous and clear cell histological types, 38% of the respondents targeted "full cylinder length". To prevent vaginal side effects, 78% of the respondents recommended using a vaginal dilator and/or sexual intercourse after VBT. Conclusions: This survey revealed variations in the clinical practice of VBT among Turkish radiation oncologists, which suggests that standardization is necessary.Item The retrospective analysis of patients with uterine sarcomas: A single-center experience(2016) Terek, Mustafa Cosan; Akman, Levent; Hursitoglu, Behiye Seda; Sanli, Ulus Ali; Ozsaran, Zeynep; Tekindal, Mustafa Agah; Dikmen, Yilmaz; Zekioglu, Osman; Ozsaran, Ahmet Aydin; 27072256Background: Uterine sarcomas are rare, malignant, gynecological tumors and show diverse histopathological features. Therefore, there is no consensus on risk factors for poor outcome and optimal treatment. The aim of this retrospective analysis is to report the clinical outcome of patients with uterine sarcoma treated at a single center. Materials and Methods: The data was obtained regarding the patient's demographic characteristics, pathological results, treatments given, survival, and complications of all uterine sarcoma patients treated in a single center between the years 2000 and 2012. The 80-month overall survival (OS) was determined with respect to prognostic factors including age, stage of disease, histopathological type, and adjuvant treatment. Results: A total of 57 case records are retrieved for this retrospective analysis. The mean age of the patients is 62.5 +/- 11.2 years. International Federation of Gynecology and Obstetrics (FIGO) stage distribution is stage I: 29; stage II: 13; stage III: 9; stage IV: 6. Fifty-seven patients underwent surgery, 33 received postoperative radiotherapy (PORT), and 32 received chemotherapy. Median follow-up period was 25 months (range 2-85 months). The 80-month OS for the entire group of patients was 36.7%. The significant prognostic factors for survival are age under 50 years, stage of disease, and adjuvant chemotherapy. Conclusion: Although limited by small sample size and retrospective nature, age under 50 years, stage of disease, and adjuvant chemotherapy are significant prognostic factors for survival for uterine sarcomas.
