E.1 Medical condition or disease under investigation |
E.1.1 | Medical condition(s) being investigated |
Patients aged >=70 years with T1 N0 breast cancer (dimensions <2 cm and negative axillary lymph nodes) with luminal A-like characteristics (ER >=10% PgR >20% HER2 negative Ki67 <20%), after conservative surgery amenable with postoperative partial breast irradiation. The aim of the study is to evaluate the health-related quality of life (HRQoL) and safety of the irradiation arm. |
Pazienti con età uguale o superiore a 70 anni con tumore della mammella T1 N0 (dimensioni fino a 2 cm e linfonodi ascellari negativi) luminale A-like (ER >=10% PgR >20% HER2 negativo Ki67 <20%), dopo chirurgia conservativa, candidabili a radioterapia postoperatoria e terapia endocrina adiuvante. Lo studio si propone di valutare la qualità della vita e la sicurezza dell’irradiazione parziale della mammella esclusiva in questa popolazione di pazienti potenzialmente fragile. |
