BACKGROUND: This study evaluated whether young breast cancer patients (≤ 40 y of age) with luminal subtypes and stage pT1N0 can benefit from chemotherapy (CHT).

MATERIALS AND METHODS: This study included 688 patients aged ≤ 40 y with luminal subtypes and stage pT1N0 breast cancer. The overall survival and disease-free survival (DFS) rates in the whole cohort and subgroups were compared between patients receiving CHT followed by endocrinotherapy (ET) (CHT→ET group) and those receiving only ET (ET-alone group).

RESULTS: Univariate analysis identified that the tumors in the CHT→ET group were more aggressive than those in the ET-alone group. However, the overall survival and DFS rates did not differ significantly between the CHT→ET and ET-alone groups (P = 0.416 and 0.21, respectively), implying that a subgroup of patients could benefit from CHT. Subgroup analysis of DFS rates revealed that patients with human epidermal growth factor receptor 2 overexpression (P = 0.042), histological classification grade 3 (P = 0.030), progesterone receptor ≤ 20% (P = 0.033), and clinical stage T1c (P = 0.038) could benefit from CHT. Further analysis showed that these four risk factors combined predicted whether the patient could benefit from CHT.

CONCLUSIONS: Young patients with hormone receptor-positive and stage pT1N0 breast cancer may benefit from CHT only if they exhibit at least two of the following risk factors: progesterone receptor ≤ 20%, human epidermal growth factor receptor 2 overexpression, histological grading 3, or clinical stage T1c.
