After the intensity of gastrointestinal cancer, we now turn our attention to genitourinary (GU) cancers with the upcoming ASCO GU meeting later this week in Orlando.
Two of the big topics here will be prostate and renal cell (RCC) cancers.
Unfortunately, the long awaited data in adjuvant RCC demonstrated that early treatment with sorafenib or sunitinib did not improve outcomes in locally advanced kidney cancer after resection. According to the ASCO press release, the trial conducted by Dr Haas and colleagues at U Penn discovered that:
“The average period to disease recurrence was similar between those who received sorafenib or sunitinib after surgery (5.6 years) and those treated with placebo (5.7 years).”
We will therefore turn our attention to castration resistant prostate cancer (CRPC).
One of the recent and ongoing controversies is splice variants, especially AR-V7, which is thought by some research groups to confer resistance to the hormonal therapies, enzalutamide and abiraterone. The big question though, is does it, and how useful is an assay in helping to determine appropriate therapy? Are there other factors at play?
We looked at the latest data and put the findings in context with what we know from other published research.
