Os destaques do programa científico do San Antonio Breast Cancer Symposium (SABCS 2022) e seu impacto na prática clínica estão em foco no PODCAST ONCONEWS, com apresentação de Silvio Bromberg e Daniel Gimenes. Nesta edição os especialistas recebem Karla Kabbach, patologista do Hospital Israelita Albert Einstein e docente na Universidade Federal de São Paulo (Unifesp), que discute trabalhos que avaliam o status HER2-low e a expressão Ki67 no câncer de mama. Confira.
