Immunohistochemical expression of estrogen receptor, progestin receptor, Ki67, and L1 cell adhesion molecule (L1CAM) was detected. Univariate Cox regression, LASSO regression, and stepwise Cox regression were applied for identifying independent risk factors for EC recurrence.

The areas under the curves at 1-, 3-, and 5-year RFS in low-grade and high-grade groups were 0.881/0.825, 0.888/0.853, and 0.807/0.832, respectively.

It has high clinical application value and provides decision making information regarding RFS for both low-grade and high-grade EC patients.
