I was diaagnosed with prostate cancer Mar. 2007 had 4.2 psa and glleason score 3+4=7 had R.P. April 07 and my first psa after R.P. was .01  in July 2007 -- .05  in Oct. 2007 and 1.0 in Jan. 2008, would these  numbers be concidered doubling and if so what's my next move, the Doctor say's  to check it again in 3 months, Thanks Gary garybobb Mon, 11 Feb 2008 00:00:00 GMT PSA doubling is the amount of time it takes for your PSA to double.   Most would say patients with a doubling time of three to 12 months are at a significant risk for the development of systematic disease.   Since you had a RP your PSA should be 0.  You have residual disease and I would want to be more agressive than a repeat PSA.

If so, then your PSA doubling time is less than a month -- extremely dangerous:   07/2007 ... 0.01 (perhaps misread from "<0.01") (08/2007 ... 0.0069) (09/2007 ... 0.0185)  10/2007 ... 0.05 (11/2007 ... 0.136) (12/2007 ... 0.367)  01/2008 ... 1.0 (calculated as an increase of 2.7 per month) ? 02/2008 ... 2.7 (projected, assuming an increase of 2.7 per month) ? 03/2008 ... 7.3 (projected, assuming an increase of 2.7 per month) ? 04/2008 ... 20 (projected, assuming an increase of 2.7 per month) ? 05/2008 ... 53 (projected, assuming an increase of 2.7 per month)Such an aggressive doubling rate is extremely rare, and so I suspect that some kind of miscommunication has taken place. But even if your January value was 0.1 rather than 1.0, it represents a three-month doubling time -- still quite worrisome. If it were me, I wouldn't wait another three months; I'd schedule a consultation with another medical oncologist as soon as possible. /Paul in Los Angeles  PaulC2 Sun, 16 Mar 2008 00:00:00 GMT
