Latest Salvage Radiation News:

"For the study, 388 patients with pT3-4pN0 prostate cancer with positive or negative surgical margins were recruited. After RP, 307 men achieved an undetectable PSA (arms A + B). In 78 patients the PSA remained above thresholds (median 0.6, range 0.05-5.6 ng/mL). Of the latter, 74 consented to receive 66 Gy to the prostate bed, and SRT was applied at a median of 86 days after RP. Clinical relapse-free survival, metastasis-free survival, and overall survival were determined by the Kaplan-Meier method.RESULTS:
Patients with persisting PSA after RP had higher preoperative PSA values, higher tumor stages, higher Gleason scores, and more positive surgical margins than did patients in arms A + B. For the 74 patients, the 10-year clinical relapse-free survival rate was 63%. Forty-three men had hormone therapy; 12 experienced distant metastases; 23 patients died. Compared with men who did achieve an undetectable PSA, the arm-C patients fared significantly worse, with a 10-year metastasis-free survival of 67% versus 83% and overall survival of 68% versus 84%, respectively."

Researchers in Germany have completed a followup study on 151 patients. The median followup time was 82 months.
They found a 55% recurrence rate in salvage radiation (SRT) patients. This confirms several other studies around the world that show in the long term, most salvage radiation patients will show at least biochemical recurrence. (In the short run, it's just the opposite) . However, the study also showed very few prostate cancer deaths during the followup period. And the study confirmed other research since 2004: pre-SRT PSA level is a critical factor in predicting the outcome of salvage radiation.  The lower your PSA at the time of salvage radiation, the better.  The takeaway? If you're considering salvage radiation, don't dally.

Latest PSA is < 0.1, now 7 years out from salvage radiation.

Blood draw for annual PSA this morning. Stay tuned...

Zero point five: a number to remember

Earlier is better when it comes to salvage radiation therapy (SRT) another study reports. This had been clearly identified by Stephenson et al., in the past. This time the study comes from Italy and is reported in European Urology: nearly 3/4 of men who had SRT at PSA levels of 0.5 or lower were alive and  free of biochemical progression nearly 5 years later.  (Being free of biochemical progression basically means undetectable PSA).

So if your PSA has risen after prostatectomy, and you're considering radiation as a second attempt at a cure, time is of the essence. If your doctor says it's okay to wait until you hit 1.0, or, God forbid, 2.0; run, don't walk, to get a second opinion from a radiation oncologist who is more up-to-date on the literature. 

A lot of the time with prostate cancer, time isn't that critical. But with salvage radiation, the clock is ticking.

REFERRED FOR RADIATION

Day before radiation commenced, PSA = 0.7

Radiation Jan-Mar 2007.  PSA quickly fell to less than 0.1 and remains there as of early 2013, now age 51.
No side effects from radiation at this point.
