Cohort of propensity score matching of patients with no high-risk features (negative margin, no nodal involvement, and no lymphovascular invasion).
All the treatments are in the adjuvant setting. Categorical variables presented in number (%) and continuous variables presented as meanstandard deviation.
Chemo indicates chemotherapy; Chemo-RT, chemotherapy followed by radiation.
