Prostate Cancer

Is a PSA Drop from 4900 to 1.8 in 3 Months Commmon?

01/25/2001

Question:

I have been diagnosed with advanced prostate cancer that has spread to the bones. My PSA originally was 4,900 ... after hormonal treatment and radiation to the bones, my PSA is 1.8. Is such a large range of the PSA common? And does that mean the cancer is contained and finished for the moment? This PSA range was within a 3 month time frame.

Answer:

The change in PSA represents a response to treatment and an indication that the tumor has markedly been reduced in volume and growth activity. It is important that you be monitored with periodic PSA determinations to assess your status. Your physician should be able to keep you updated based on these measurements.
