ABSTRACT

Introduction: Endometrial cancer is the most common invasive gynecologic malignancy in developed countries. The best survival rates are expected after surgical removal, thus the aim of a complex treatment is to achieve resecability in locally and locoregionally advanced disease. Aim: The primary purpose of this study was to evaluate if the neoadjuvant systemic treatment leads to better overall survival compared to irradiation solely. Method: From January 2015 to December 2018, we enrolled 28 patients diagnosed with irresecable, locally and locoregionally advanced high-risk endometrial carcinoma. Patients were treated by neoadjuvant paclitaxel-carboplatin, then radical hysterectomy, bilateral oophorectomy and lymphadenectomy were performed. Results: After administration of 6 cycles of carboplatin-paclitaxel, the control MR test showed tumor shrinkage in all patients. Complete resection was achieved in the case of every patient. Tumor residuum in lymph nodes was verified in 4 cases by pathological evaluation. The 2-year survival and the 2-year progression-free survival rates were 65,1% and 66,1%, respectively. The median overall survival was 16,5 months. Conclusion: Neoadjuvant treatment can be an effective approach in providing the conditions for complete tumor resection, which may result in survival advantage. Despite multimodal treatment, prognosis is poor. Orv Hetil. 2020; 161(11) 425-433.
