  • The purpose of The Cancer and Leukemia Group B (CALGB) 90203 trial is to determine which of 2 treatment strategies is superior in treating men with high-risk, clinically localized adenocarcinoma of the prostate (stage T1 to T3a NX M0), defined as a predicted probability < or =60% of remaining free from disease recurrence for 5 years after surgery. Patients with a > or =10-year life expectancy will be randomized to either radical prostatectomy (RP) alone versus estramustine and docetaxel before RP. Participants will be excluded if they have received prior therapy for prostate cancer (except transurethral resection of the prostate) or are judged not to be appropriate candidates for RP. Eligible patients will be stratified according to their predicted probability of remaining free from disease recurrence at 5 years after surgery (0% to 20%, 21% to 40%, and 41% to 60%) and randomized. Neoadjuvant chemotherapy will be 6 cycles (1 cycle = 21 days) of estramustine (280 mg tid, days 1 to 5) and docetaxel (70 mg/m2 on day 2). Warfarin (2 mg/day orally) will be given for prophylaxis against deep venous thrombosis. Bilateral pelvic lymph node dissection and RP will be performed within 60 days of registration/randomization for men randomized to the surgery-alone arm. For men randomized to receive preoperative chemotherapy, the surgical procedure will be performed within 60 days of completion of chemotherapy. Patients will be monitored with history review, physical examination, and serum prostate-specific antigen (PSA) levels every 3 months for the first 3 years after surgery, every 6 months for the next 3 years, and annually thereafter. Biochemical disease recurrence will be defined as a serum PSA level >0.4 ng/mL on 2 consecutive occasions > or =3 months apart after RP. The time of biochemical failure is measured from the date of randomization to the time of the first PSA level <0.4 ng/mL that is confirmed on the second serial PSA. The primary study end point is to determine if early systemic treatment with neoadjuvant estramustine and docetaxel before RP in patients with high-risk prostate cancer will decrease 5-year recurrence rates when compared with RP alone. Secondary outcomes will include (1) the safety and tolerability of neoadjuvant estramustine and docetaxel before RP; (2) the impact of this neoadjuvant strategy on pathologic tumor stage, including lymph node and surgical margin status; (3) time to clinically apparent disease recurrence; and (4) overall survival. The impact of RP with and without neoadjuvant estramustine and docetaxel on the patient's quality of life from pretreatment through year 3 will be assessed. Frozen prostate tissue will be obtained from men undergoing prostatectomy who are enrolled in either the treatment or control arms of the trial. These samples will be analyzed for their RNA expression patterns in order to build outcome prediction models. Furthermore, using array-based methods of expression analysis, the sensitivity to chemotherapeutic agents and response to chemotherapy may likewise be predicted. The trial will enroll approximately 700 men during a 48-month period. Patients will be observed for 84 months after study closure. The power to detect a 36% decrease in 5-year recurrence rates is 90%.
