    Is there any benefit of paraaortic field irradiation in pelvic lymph node positive endometrial cancer patients? 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-5654-2020
    We 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.

    Good Outcomes of Patients with Stage IB Endometrial Cancer with Surgery Alone
    (2014) Rahatli, Samed; Dizdar, Omer; Kucukoztas, Nadire; Oguz, Arzu; Yalcin, Selim; Ozen, Ozlem; Reyhan, Nihan Haberal; Tarhan, Cagla; Yildiz, Ferah; Dursun, Polat; Altundag, Ozden; Ayhan, Ali
    Background: Most patients with endometrial cancer have stage I disease. Adjuvant therapy in stage IB (formerly IC) endometrial cancer is controversial, treatment options including observation or brachytherapy/radiotherapy in grade 1-3 patients with or without chemotherapy. The purpose of this study was to assess the outcomes of our patients with stage IB endometrioid endometrial cancer. Materials and Methods: Sixty two patients with stage IB endometrial cancer and endometrioid histology were retrospectively evaluated. All patients were initially treated surgically by the same surgeon with comprehensive staging, i.e. total abdominal hysterectomy, bilateral salphingooopherectomy, bilateral pelvic and paraaortic lymph node dissection and omentectomy. Adjuvant radiotherapy was discussed with patients and utilized by those who accepted. Adjuvant chemotherapy was not given to any of the patients. Results: Median age was 62 (range, 42-95). Ninety percent of the patients had grade 1-2 disease. Thirteen patients (21%) received intra vaginal brachytherapy (IVBT) and one received whole pelvic radiotherapy (WPRT). Median follow-up time was 46 months (range, 9-77 months). Three patients experienced recurrence (4.8%), two of them died on follow-up and one was still alive at last visit. Two patients with recurrence had FIGO grade 2 tumors and one had a grade 3 tumor. Two patients (3.2%) died without evidence of recurrent disease. Relapse free survival at 5 years was 94.4% and overall survival was 93.1%. Conclusions: Patients with stage IB disease in our study demonstrated relatively low recurrence rates with this stage of endometrial cancer.
