Depth of myometrial infiltration, stromal cervical involvement, FIGO staging and death were variables that presented a statistically significant difference between patients with and without recurrence.Abstract 418 Figure 1 Conclusions This study ratifies the depth of myometrial infiltration greater than 50%, cervical stromal invasion and staging according to FIGO 2009 criteria are important prognostic factors in the recurrence of endometrial cancer. The recurrence of this tumor is related to a reduction in overall survival. These data are compatible with the existing literature and complement the scarce casuistica on endometrial cancer in Brazil.Acknowledgments To the entire gynecologic oncology group of ISCMPA, especially Professor Gustavo Py Gomes da Silveira.
