Int J Radiat Oncol Biol Phys 2024; 118:672-681. [PMID: 37788716 DOI: 10.1016/j.ijrobp.2023.09.018] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/12/2023] [Revised: 08/08/2023] [Accepted: 09/13/2023] [Indexed: 10/05/2023]
Abstract
A secondary analysis of 2 randomized Radiation Therapy Oncology Group trials demonstrated that age ≥70 years was a favorable prognostic factor among men treated with external beam radiation therapy (EBRT). In contrast, several series based on men undergoing radical prostatectomy (RP) suggested that older age was an unfavorable prognostic factor. Our study was initiated to determine whether these observations reflect a true but paradoxical underlying age-related treatment-dependent biological phenomenon. We conducted a systematic review (PubMed, January 1, 1999-January 30, 2023) evaluating the effect of age on cancer-specific outcomes after definitive local treatment with either RP or EBRT. Our main objective was to assess possible interactions between age (using a cutoff of 70 +/- 5 years) and treatment type, with regard to adverse cancer-specific outcomes (eg, pathology, biochemical failure, distant metastasis, or prostate cancer-specific survival). Forty-five studies were selected for inclusion in this systematic review, including 30 and 15 studies with patients treated with RP and EBRT, respectively. Among patients treated with RP, 10 (50%) of these studies suggested that older age was associated with worse outcome(s) after RP. None suggested that age was a favorable prognostic factor after RP. Among the EBRT-based studies, 8 (53%) suggested that older age was associated with better outcomes, with an additional 3 studies (21%) trending to support a better outcome. None of these studies involving EBRT suggested that older age was an adverse prognostic factor. This systematic review suggests that age using a categorical cutoff of 70 +/- 5 years may be an adverse prognostic factor for men undergoing RP but a favorable prognostic factor for men treated with EBRT. Further research is needed to validate these findings.

Jeong JU, Nam TK, Song JY, Yoon MS, Ahn SJ, Chung WK, Cho IJ, Kim YH, Cho SH, Jung SI, Kang TW, Kwon DD. Favorable prognosis of patients who received adjuvant androgen deprivation therapy after radiotherapy achieving undetectable levels of prostate-specific antigen in high- or very high-risk prostate cancer. PLoS One 2021; 16:e0248461. [PMID: 33711055 PMCID: PMC7954315 DOI: 10.1371/journal.pone.0248461] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/02/2020] [Accepted: 02/27/2021] [Indexed: 11/17/2022] Open
Abstract
Introduction To determine the prognostic significance of long-term adjuvant androgen deprivation therapy (A-ADT) over 1 year in achieving undetectable levels of prostate-specific antigen (PSA) less than 0.001 ng/mL in prostate cancer patients with high- or very high-risk prostate cancer who underwent radiotherapy (RT). Materials and methods A total of 197 patients with prostate cancer received RT, with a follow-up of ≥12 months. Biochemical failure was defined as PSA ≥nadir + 2 ng/mL after RT. We analyzed clinical outcomes, including survival, failure patterns, and prognostic factors affecting outcomes. Results Biochemical failure-free survival (BCFFS), clinical failure-free survival, distant metastasis-free survival, cancer-specific survival, and overall survival (OS) rates at 5 years were 91.1%, 95.4%, 96.9%, 99.5%, and 89.1%, respectively. Administration of long-term A-ADT significantly predicted favorable BCFFS (p = 0.027) and OS (p < 0.001) in multivariate analysis. Nadir PSA ≤0.001 ng/mL was an independent prognostic factor for BCFFS (p = 0.006) and OS (p = 0.021). The use of long-term A-ADT significantly affected nadir PSA ≤0.001 ng/mL (p < 0.001). The patients with A-ADT for 1 year or longer had better BCFFS or OS than those for less than 1 year or those without A-ADT (p < 0.001). The best prognosis was demonstrated in patients treated with long-term A-ADT and nadir PSA ≤0.001 ng/mL in BCFFS (p < 0.001). Conclusion The addition of long-term A-ADT over 1 year to RT demonstrated good treatment outcomes in patients with locally advanced prostate cancer. Achieving a nadir PSA value ≤0.001 ng/mL using combination therapy with RT and A-ADT is a powerful clinical predictor of treatment outcomes.

Abstract
Objective Androgen deprivation therapy (ADT) is beneficial for unfavorable intermediate-risk (IR) prostate cancer patients receiving curative radiotherapy (RT). However, for favorable IR patients the latest NCCN guidelines recommends RT alone. We retrospectively studied treatment patterns and outcomes of patients with IR prostate cancer in our institution over the past two decades. Materials and methods Three hundred seventy-three IR prostate cancer patients treated with definitive RT between 5/2002–5/2016 were identified in an institutional review board approved database. All patients received conformal RT to the prostate while the vast majority did not receive nodal radiation. ADT was commenced 2 months prior to RT and was continued for 4 months after RT. Results Compared to RT alone, patients receiving combined RT+ ADT had more positive biopsy cores, higher pre-radiation PSA, more IR factors, and were more likely to receive pelvic lymph node radiation. However, there were no differences in failure either biochemical, local or distal, nor on survival between the favorable RT alone and the unfavorable RT+ ADT cohorts, suggesting a beneficial role for ADT. On multivariate analysis, patients 70 years or younger receiving RT alone were at increased risk for biochemical failure during a 6-year follow-up (HR 3.06, P = 0.025). Biochemical relapse free survival in patients ≤70 years who received RT alone was 82.1% vs 94.0% for RT + ADT (P = 0.030). There was no difference for combined treatment modality in patients > 70 years (P = 0.87). Conclusions Men 70 years or younger with favorable IR prostate cancer treated with RT alone to 78 Gy are at increased risk of biochemical failure. Short term ADT should be considered in this cohort of men.

Prostate-Specific Antigen 5 Years following Stereotactic Body Radiation Therapy for Low- and Intermediate-Risk Prostate Cancer: An Ablative Procedure? Front Oncol 2017; 7:157.

Abstract
Background Our previous work on early PSA kinetics following prostate stereotactic body radiation therapy (SBRT) demonstrated that an initial rapid and then slow PSA decline may result in very low PSA nadirs. This retrospective study sought to evaluate the PSA nadir 5 years following SBRT for low- and intermediate-risk prostate cancer (PCa). Methods 65 low- and 80 intermediate-risk PCa patients were treated definitively with SBRT to 35–37.5 Gy in 5 fractions at Georgetown University Hospital between January 2008 and October 2011. Patients who received androgen deprivation therapy were excluded from this study. Biochemical relapse was defined as a PSA rise >2 ng/ml above the nadir and analyzed using the Kaplan–Meier method. The PSA nadir was defined as the lowest PSA value prior to biochemical relapse or as the lowest value recorded during follow-up. Prostate ablation was defined as a PSA nadir <0.2 ng/ml. Univariate logistic regression analysis was used to evaluate relevant variables on the likelihood of achieving a PSA nadir <0.2 ng/ml. Results The median age at the start of SBRT was 72 years. These patients had a median prostate volume of 36 cc with a median 25% of total cores involved. At a median follow-up of 5.6 years, 86 and 37% of patients achieved a PSA nadir ≤0.5 and <0.2 ng/ml, respectively. The median time to PSA nadir was 36 months. Two low and seven intermediate risk patients experienced a biochemical relapse. Regardless of the PSA outcome, the median PSA nadir for all patients was 0.2 ng/ml. The 5-year biochemical relapse free survival (bRFS) rate for low- and intermediate-risk patients was 98.5 and 95%, respectively. Initial PSA (p = 0.024) and a lower testosterone at the time of the PSA nadir (p = 0.049) were found to be significant predictors of achieving a PSA nadir <0.2 ng/ml. Conclusion SBRT for low- and intermediate-risk PCa is a convenient treatment option with low PSA nadirs and a high rate of early bRFS. Fewer than 40% of patients, however, achieved an ablative PSA nadir. Thus, the role of further dose escalation is an area of active investigation.

Brachytherapy improves outcomes in young men (≤60 years) with prostate cancer: A SEER analysis. Brachytherapy 2017; 16:323-329. [PMID: 28139417 PMCID: PMC5568111 DOI: 10.1016/j.brachy.2016.12.010] [Citation(s) in RCA: 4] [Impact Index Per Article: 0.6] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/07/2016] [Revised: 12/09/2016] [Accepted: 12/20/2016] [Indexed: 11/21/2022]
Abstract
PURPOSE The aim of the study was to compare prostate cancer-specific mortality (PCSM) in young men with clinically localized prostate cancer treated by either external beam radiation (EBRT) alone or brachytherapy with or without external beam radiation. METHODS AND MATERIALS Utilizing the Surveillance, Epidemiology and End Results database, 15,505 patients ≤60 years of age diagnosed with prostate cancer between 2004 and 2009 and treated with radiation therapy alone were identified. Incidence of PCSM was determined for both groups and compared using competing risk models. RESULTS The overall 8-year PCSM for the study population was 1.9% (95% confidence interval [CI]: 1.6-2.2). For patients treated with EBRT or brachytherapy with or without external beam, the 8-year PCSM was found to be 2.8% (CI: 2.2-3.4) and 1.2% (CI: 0.9-1.6), respectively (p < 0.001). Univariable analysis demonstrated that brachytherapy was associated with lower PCSM risk (hazard ratio = 0.40; CI: 0.30-0.54; p < 0.001). High Gleason risk category, black race, higher Tumor (T) stage, and higher grade were all associated with greater mortality risk (p < 0.01). On multivariable analysis, brachytherapy continued to be associated with a significantly lower mortality risk (hazard ratio = 0.65; CI: 0.47-0.89; p = 0.008). Subgroup analyses found that among those with Gleason score ≥8, younger patients had increased risk of PCSM (p = 0.001). CONCLUSIONS In men ≤60 years of age with prostate cancer, radiation therapy continues to offer excellent outcomes. After adjusting for relevant variables, the use of brachytherapy was associated with reduced PCSM compared to treatment with EBRT alone.

Radiotherapy for early-stage prostate cancer in men under 70 years of age. TUMORI JOURNAL 2015; 102:209-16.

Abstract
AIMS To demonstrate that radiotherapy (RT) is a valid alternative to surgery in men ≤70 years old with localized prostate cancer. METHODS From 1988 to 2009, 214 patients with T1-2 N0 M0 prostate cancer were treated with RT. The effects of patient- and treatment-related risk factors on toxicity were investigated. RESULTS Median follow-up was 105 months (range 14.2-180). The 5-, 10-, and 15-year biochemical relapse-free survival for all 214 patients was 80%, 61.9%, and 57.5%, respectively. In bivariate analysis, age (≤65 vs 65-70 years) was not a significant factor for biochemical relapse, while radiation dose was (p = 0.05) in multivariate analysis. Cancer-specific survival rates at 5, 10, and 15 years were 98.4%, 93.2%, and 69.7%, respectively. Median overall survival (OS) was 167 months (95% confidence interval 147.3-186.7). The OS rates at 5, 10, and 15 years were 91.8%, 75.8%, and 42.5%, respectively. Acute genitourinary (GU) and gastrointestinal (GI) toxicities occurred in 105 (49%) and 98 patients (45.8%), respectively, with only 2 cases of grade III GI toxicity. Late GU and GI toxicities occurred in 17 (7.9%) and 20 (9.3%) patients, respectively, with 1 grade III GI toxicity and 2 grade III GU toxicities. Risk factors for late toxicity were age and RT dose and technique, which were unrelated to acute toxicity. CONCLUSIONS Age ≤70 years does not consistently confer a negative prognosis for localized prostate cancer. Radiotherapy appears to be a viable alternative to surgery, offering excellent long-term cancer control.
