Hi, I got this from Radiation Oncology. Survival of women with clear cell and papillary serous endometrial cancer after adjuvant radiotherapy Type II (papillary serous and clear cell) endometrial carcinoma (EC) is a rare subgroup and is considered to have an unfavorable prognosis. Five-year local recurrence free survival (LRFS), distant metastases free survival (DMFS) and overall survival (OS) were 85.4%, 78%, and 64.5% respectively. I hope this can help you a bit.
