Less radiation is non-inferior, this is for low and intermediate-risk localized prostate cancer patients. Would like input from our radiation oncologists as to whether or not this adoptable?
Protons vs IMRT for localized prostate cancer showed no difference in outcome or quality of life. There will be longer f/u and other endpoints studied but the take-home message is that protons are not significantly better than photons.
Will we be replaced by AI? It seems that for radiologists, an AI system was better than the human counterpart in this study looking at prostate cancer diagnostic imaging. I doubt many of us would accept a solely computer-generated report, but this study highlights how AI may help as a supportive tool in the primary diagnostic setting. Of course, prospective validation will be needed.
10-year metastasis-free survival was 71.9% in the short-course ADT group (6 months) and 78% in the long-course ADT group (24 months). So, it seems the longer the duration, the better the outcome. 93% had a Gleason score of 7 or higher.
We know that combination PARP and antiandrogen is better than antiandrogen alone. I have wondered if we need antiancrogen on those patients. This shows that, YES, we do. The combination also was better than PARP inhibitor monotherapy in those patients carrying HRRm.
It might be costly to get the PET scans but helps with prognosis and directing patients to palliative care since positive lesions in all predicts shorter overall survival.
The role for immunotherapy in combination with multitargeted therapy in prostate cancer, for patients who had previous docetaxol, or had visceral disease (liver) showed more benefit from the combination vs. second novel hormonal therapy. Recall that patients who had exposure to docetaxol can be treated with pluvicto. Genomic and genetic testing is encouraged for those patients as PARP targeted mutations can be found (homologous recombination-repair mutations).
SBRT improves PFS in addition to antiandrogen therapy. The question is, with oligomets, do we need systemic therapy in all patients? Or will SBRT be sufficient?
I encourage our FCS radiation oncologists to provide their input on this study, as well.
Our radiation oncologists will find this article particularly interesting – more radiation is NOT better.
Pembrolizumab plus olaparib did not significantly improve radiographic progression-free survival or overall survival versus new generation hormonal agent and was more toxic.
FCS Hematology Oncology Review creates a platform for our physician network to observe the most recent articles and studies available in the oncology and hematology world. By sharing these articles we are building our wealth of knowledge of new observations and treatments as they come available.
