How does Decipher score inform your practice for treating pelvic nodes in otherwise favorable intermediate risk prostate cancer?
Would a higher Decipher score, despite low risk for nodal disease based on MSKCC nomogram or Roach formula, encourage you to treat the pelvic lymph nodes?
Answer from: Radiation Oncologist at Academic Institution
Nodal radiation therapy in prostate cancer remains controversial. While the Decipher score correlates with lymph node involvement in pathological specimens, I have not used it to decide on pelvic nodal radiation. Two randomized studies failed to show a benefit to pelvic radiation (old studies with i...

It's not unreasonable to use any valid predictor in decision making. I use the Partin tables and MSK nomograms as a predictor of lymph node involvement, and if the rate is less than 10%, don't treat the nodes, and if it's 10%+, consider it. A very high decipher score indicates an increased risk of m...

I would be hard pressed based on current evidence to consider adding LNRT to an FIR patient because of a Decipher score.
I personally go by MSKCC nomogram with a threshold of 15% and have, to date, not met an FIR patient who would meet the criteria. Some UIR patients can meet those criteria without...
