When would you continue bevacizumab versus using PARPi alone for maintenance therapy in BRCA+ or HRD+ ovarian cancer after response to primary platinum + bevacizumab?
Are there clinical factors which help stratify? Does your practice vary based on mutation status (BRCA+ vs HRD+?)
Answer from: at Community Practice
In patients who start treatment with combination platinum based chemotherapy + bevacizumab, and are found to be BRCA+ or HRD+, I will commonly continue bevacizumab and layer on the PARPi in the maintenance setting. This is based on both the PAOLA-1 data, as well as the population adjusted indi...

If patient has germline or somatic BRCA mutation or HRD positive, we add olap...
