Does prolonged anti-inflammatory therapy reduce number of unnecessary repeat saturation prostate biopsy?

The effect of a prolonged oral anti-inflammatory therapy on PSA values in patients with persistent abnormal PSA values after negative prostate biopsy (PBx) was evaluated.

From September 2011 to September 2012, 70 patients (medi- an age 62 years), with persistent abnormal PSA values after negative extended PBx, were given an herbal extract with anti-inflammatory activity for 3 months (Lenidase®; 1 tablet daily constituted of baicalina, bromelina and escina). All patients were submitted to prostate biopsy for: abnormal DRE; PSA > 10 ng/mL, PSA values between 4.1-10 or 2.6-4 ng/mL with free/total PSA < 25% and < 20%, respectively. Three months after the end of anti-inflammato- ry therapy all patients were revaluated; indication for repeat saturation biopsy (SPBx) and detection rate for PCa were compared with those previously recorded in our Department using the same inclusions criteria for biopsy.

Oral administration of Lenidase® was well tolerated and no side effects were observed; PSA values decreased in 54 (77.8%) out 70 patients with a median PSA reduction of 20.5% (from 8.8 to 7 ng/mL) and remained unchanged in 16 patients (22.2%); the repeat SPBx rate resulted significantly lower (22.8% vs 35.5%; p < 0.05) showing a superimposable detection rate for PCa (3 cases) in comparison with our previous data (18.7% vs 22%).

In our preliminary data a prolonged oral anti-inflammatory therapy reduced PSA levels in patients with negative PBx and persistent suspicious for PCa decreasing the indication to perform repeat SPBx (about 30% of the cases).
