Prostate cancers in patients with a mutation in BRCA2 have earlierdisease onset and an aggressive course, often necessitatingthe use of systemic therapy. However, these tumours are DNArepair-defective and could respond favourably to Parp inhibitors orDNA-damaging agents, depending on the therapeutic ratio (ratio oftumour response to normal tissue toxicity). We describe 3 patientstreated with precision radiotherapy or cisplatin who respondedfavourably to both agents, yet did not suffer undue
