Abstract
Could the Long-Term Oncological Safety of Laparoscopic Surgery in Low Risk Endometrial Cancer be also valid for the High Intermediate and High-Risk Patients? A Multi-center Turkish Gynecologic Oncology Group Study Conducted with 2745 Endometrial Cancer Cases. (TRSGO-End-001)Aim: to compare the long-term oncological outcomes of laparotomy and laparoscopic surgeries in endometrial cancer under the light of 2016 ESMO-ESGO-ESTRO risk classification system with particular focus on the high intermediate and high-risk categories.Methods: Using multicentric database between January 2005 and January 2016, disease-free and overall survivals of 2745 endometrial cancer cases were compared according to the surgery route, laparotomy vs laparoscopy. The high intermediate and high-risk patients were defined with respect to the 2016 ESMO-ESGO-ESTRO risk classification system and they were analyzed with respect to difference in survival rates.Results: Of the 2745 patients 1743 (63.5%) were operated by laparotomy, and the remaining were operated with laparoscopy. The total numbers of high intermediate and high-risk endometrial cancer cases were 734 (45%) patients in the LT group and 307 (30.7%) patients in the LS group. Disease-free and overall survivals were not statistically different when compared between laparoscopy and laparotomy groups in terms of low, intermediate, high intermediate and high-risk endometrial cancer.Conclusions: Regardless of the endometrial cancer risk category, long-term oncological outcomes of laparoscopic approach were found to be comparable to those treated with laparotomy. Our results are encouraging to consider laparoscopic surgery for high intermediate and high-risk endometrial cancer cases.
