Results suggest the efficacy of trastuzumab deruxtecan is influenced by the spatial distribution of HER2 in breast tumour cells
A translational analysis of the DAISY trial improves knowledge on the mechanisms of action of the antibody–drug conjugate

Interim analysis shows that the safety of sacituzumab govitecan is in line with expectations
In the SASCIA trial, sacituzumab govitecan was associated with a higher incidence of adverse events and dose delays than treatment of physician’s choice in patients with HER2-negative breast cancer at high risk of relapse, but dose reductions occurred with a similar frequency in both arms

Combining PARP1 inhibition with an ATR inhibitor does not improve outcomes in pre-treated metastatic TNBC
Results from the VIOLETTE trial also suggest that mutation status may influence response to each agent

Do CDK4/6 inhibitors affect fertility and are they beneficial in premenopausal women?
Two studies hint at a lack of effect of palbociclib on ovarian function and demonstrate similar reduced recurrence with abemaciclib regardless of menopausal status

Positive patient-reported outcomes data expand on the efficacy benefits of trastuzumab deruxtecan and pembrolizumab
Two studies show that quality of life was maintained or improved with new treatments for advanced breast cancer

The future of personalised risk-stratified breast cancer screening
Will widespread screening for breast cancer based on individual risk mean the end of the one-size-fits-all standard mammogram?

Optimising adjuvant treatment in HR+/HER2-negative early breast cancer
Gene-expression assays have produced a huge step forward in identifying patients who are likely to benefit from adjuvant chemotherapy but there is still a long way to go in the more specific targeting of treatment

Sibylle Loibl receives the ESMO Breast Cancer 2022 Award
In her Keynote Lecture at ESMO Breast Cancer 2022, Prof. Sibylle Loibl looks at neoadjuvant therapy and the fertility and pregnancy issues facing young women with breast cancer

Is molecular profiling useful in the management of breast cancer?
The value of genomic testing is being increasingly demonstrated and will evolve over time
