Univariate regression analysis for the low‐grade group indicated that age, FIGO Stage, ER, PR, L1CAM, LVSI, tumor size, cervical stromal infiltration, pelvic lymph nodes, muscle layer infiltration, and para‐aortic lymph nodes may be important factors influencing RFS in the low‐grade group (Table 4). This evidence concerns the gene ESR1 and neoplasm.
