Abstract
BACKGROUND: The low probability of curing high-risk prostate cancer (PC) with local therapy suggests the need to study modality of therapeutic approaches. To this end, a prospective phase II trial of neoadjuvant docetaxel (D) and complete androgen blockade (CAB) was carried out in high-risk PC patients. The primary end point was to detect at least 10% of pCRs after chemohormonal treatment.
METHODS: Patients with T1c-T2 clinical stage with prostate-specific antigen (PSA) >20 ng ml(-1) and/or Gleason score >= 7 (4 + 3) and T3 were included. Treatment consisted of three cycles of D 36 mg m(-2) on days 1, 8 and 15 every 28 days concomitant with CAB, followed by radical prostatectomy (RP).
RESULTS: A total of 57 patients were included. Clinical stage was T1c, 11 patients (19.3%); T2, 30 (52.6%) and T3, 16 (28%) patients. Gleason score was >= 7 (4 + 3) in 44 (77%) patients and PSA >20 ng ml(-1) in 15 (26%) patients. Treatment was well tolerated with 51 (89.9%) patients completing neoadjuvant therapy together with RP. The rate of pCR was 6% (three patients). Three (6%) additional patients had microscopic residual tumour (near pCR) in prostate specimen. With a median follow-up of 35 months, 18 (31.6%) patients presented PSA relapse.
CONCLUSION: Short-term neoadjuvant D and CAB induced a 6% pCR rate, which is close to what would be expected with ADT alone. The combination was generally well tolerated.
