Tailored postoperative treatment of prostate cancer: final results of a phase I/II trial. Prostate Cancer Prostatic Dis 2018; 21:564-572. [PMID: 30038390 PMCID: PMC6283858 DOI: 10.1038/s41391-018-0064-7] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/04/2018] [Revised: 04/27/2018] [Accepted: 05/24/2018] [Indexed: 11/08/2022]
Abstract
BACKGROUD The European Organization for Research and Treatment of Cancer (EORTC) trial 22,911 reported 74% 5-year biochemical disease-free survival (bDFS) in patients with prostate carcinoma treated with radical prostatectomy (RP) followed by postoperative radiotherapy (RT). This study aimed to improve these outcomes by using a combined-intensified-modulated-adjuvant treatment, including RT and hormone therapy (HT) after RP. MATERIALS AND METHODS This phase I/II trial treatment was designed to improve 5-year bDFS from ~ 75 to 90%. Patients were consecutively enrolled using the following inclusion criteria: age < 80 years, histological diagnosis of prostate adenocarcinoma without known metastases, stage pT2-4N0-1, and Eastern Cooperative Oncology Group performance status of 0-2. All patients had at least one of these pathologic features: capsular perforation, positive surgical margins, seminal vesicle invasion, and pelvic lymph nodes involvement. A minimum dose of 64.8 Gy to the tumor bed was delivered in all patients. Depending on tumor characteristics at diagnosis, patients received a higher dose (70.2 Gy; 85.4%) and/or prophylactic pelvic lymph nodes irradiation (57.7%) and/or HT (69.1%). Biochemical relapse was defined as two consecutive rising prostate-specific antigen (PSA) values > 0.2 ng/ml. RESULTS A total of 123 patients were enrolled in the study and completed the scheduled treatment. Median preoperative and postoperative PSA were: 8.8 and 0.06 ng/mL, respectively. The percentages of patients with pathologically involved nodes and positive resection margins were: 14.6% and 58.5%, respectively. With a median follow-up of 67 months (range: 37-120 months), the actuarial 5-year bDFS, local control, metastasis-free survival, and overall survival (OS) were: 92.9%, 98.7%, 96.1%, and 95.1%, respectively. CONCLUSION A higher 5-year bDFS (92.9%) was recorded compared to studies based on standard adjuvant RT, even though patients with nodal disease and detectable postoperative PSA were enrolled. Clinical end points, as long-term disease-free survival and OS, will require further assessments. (ClinicalTrials.gov: NCT03169933).

Abstract
PURPOSE To perform a preliminary feasibility acute and late toxicity evaluation of an intensified and modulated adjuvant treatment in prostate cancer (PCa) patients after radical prostatectomy. MATERIAL AND METHODS A phase I/II has been designed. Eligible patients were 79 years old or younger, with an ECOG of 0-2, previously untreated, histologically proven prostate adenocarcinoma with no distant metastases, pT2-4 N0-1, and with at least one of the following risk factors: capsular perforation, positive surgical margins, and seminal vesicle invasion. All patients received a minimum dose on tumor bed of 64.8 Gy, or higher dose (70.2 Gy; 85.4%), according to the pathological stage, pelvic lymph nodes irradiation (57.7%), and/or hormonal therapy (69.1%). RESULTS 123 patients were enrolled and completed the planned treatment, with good tolerance. Median follow-up was 50.6 months. Grade 3 acute toxicity was only 2.4% and 3.3% for genitourinary (GU) and gastrointestinal (GI) tract, respectively. No patient had late grade 3 GI toxicity, and the GU grade 3 toxicity incidence was 5.8% at 5 years. 5-year BDSF was 90.2%. CONCLUSIONS A modulated and intensified adjuvant treatment in PCa was feasible in this trial. A further period of observation can provide a complete assessment of late toxicity and confirm the BDSF positive results.

Eur Urol 2007; 52:1058-65. [PMID: 17418938 DOI: 10.1016/j.eururo.2007.03.056] [Citation(s) in RCA: 33] [Impact Index Per Article: 1.9] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/06/2006] [Accepted: 03/16/2007] [Indexed: 11/16/2022]
Abstract
OBJECTIVES To retrospectively assess the outcome of patients with initial PSA of 20 ng/ml or higher undergoing radical prostatectomy (RP) for prostate cancer (pCA). METHODS Between January 1986 and June 2005, 275 patients with preoperative PSA> or =20 ng/ml underwent RP for pCA at our institution. Overall, disease-specific and biochemical progression-free survival rates for the entire cohort and for particular subgroups were determined. RESULTS Median patient age at time of surgery was 64 yr (range: 44-75). Fifty-seven patients (20.7%) had pT2 stage, 206 (74.9%) pT3, and 10 (3.7%) pT4; 78 (28.4%) presented with local nodal metastases (pN+). To date, 40 patients have died (14.5%), 22 of pCA and 18 of other causes. Biochemical progression occurred in 92 patients (33.5%). Overall (and disease-specific) survivals at 5, 10, and 15 yr were 87% (93%), 70% (83%), and 58% (71%), respectively. These survival rates did not significantly differ between patients receiving immediate versus deferred hormonal therapy (in case of progression). Five-year PSA progression-free survival in patients on surveillance (receiving deferred hormonal treatment at the onset of rising PSA values) was 53%. For patients on immediate hormonal treatment following RP, the 5-yr hormone-refractory PSA progression rate was 76%. CONCLUSIONS According to long-term follow-up results in this high-risk cohort of patients with preoperative PSA> or =20 ng/ml, RP can be considered a viable therapeutic option. With regard to combining immediate hormonal therapy with surgery, the optimal treatment following RP remains to be defined.
