Evaluation of Recurrent Disease after Radiation Therapy for Patients Considering Local Salvage Therapy: Past vs. Contemporary Management. Cancers (Basel) 2023; 15:5883. [PMID: 38136427 PMCID: PMC10741753 DOI: 10.3390/cancers15245883] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/10/2023] [Revised: 12/14/2023] [Accepted: 12/14/2023] [Indexed: 12/24/2023] Open
Abstract
Recurrent prostate cancer after primary treatment with radiation therapy is a common problem. Patients with localized recurrence may benefit from salvage therapy, but careful patient selection is crucial because not all patients will benefit from local salvage therapy, and salvage therapy has increased morbidity compared to primary treatments for prostate cancer. This review aims to provide an overview of the evaluation of patients with recurrent disease after radiation therapy and how it is continuing to evolve with increasing data on outcomes, as well as improving technologies and techniques. Our enhanced understanding of treatment outcomes and risk stratification has influenced the identification of patients who may benefit from local salvage treatment. Advances in imaging and biopsy techniques have enhanced the accuracy of locating the recurrence, which affects treatment decisions. Additionally, the growing interest in image-targeted ablative therapies that have less morbidity and complications than whole-gland therapies for suitable patients influences the evaluation process for those considering focal salvage therapy. Although significant changes have been made in the diagnostic evaluation of patients with recurrent disease after radiation therapy, it remains unclear whether these changes will ultimately improve patient outcomes.

Immune cells markers within local tumor microenvironment are associated with EBV oncoprotein in nasopharyngeal cancer. BMC Cancer 2022; 22:887. [PMID: 35963999 PMCID: PMC9375267 DOI: 10.1186/s12885-022-09948-9] [Citation(s) in RCA: 2] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/27/2021] [Accepted: 07/29/2022] [Indexed: 11/29/2022] Open
Abstract
Introduction EBV infection in nasopharyngeal cancer ensued in latent infection mode. In this latent infection various EBV oncoproteins such as EBNA1 and LMP1 was expressed. EBV oncoproteins could theoretically recruit immune cells, which might help to control cancer. Therefore, this study was aimed to elucidate the association with EBV oncoproteins (EBNA1 and LMP1), immune markers (CD4, CD8, and FOXP3) from nasopharyngeal cancer microenvironment with tumor progression. Method Nasopharyngeal biopsy was obtained from patients suspected to have nasopharyngeal cancer. Those samples with microscopically confirmed nasopharyngeal cancer were tested for EBNA1, LMP1, CD4, CD8, and FOXP3 concentration with ELISA, then verified with IHC. Each patient tumor volume was assessed for primary nasopharyngeal tumor volume (GTVp) and neck nodal metastases tumor volume (GTVn). Correlation test with Spearman correlation and scatterplot were carried out. Result Total 23 samples with nasopharyngeal cancer were analyzed. There was moderate correlation (ρ = 0.45; p value = 0.032) between LMP1 and GTVp. There was strong correlation (ρ = 0.81; p value < 0.001) between CD8 and GTVp. There was also moderate correlation (ρ = 0.6; p value = 0.002) between FOXP3 and GTVp. The CD8 concentration has moderate correlation with both EBNA1 (ρ = 0.46; p value = 0.026) and LMP1 (ρ = 0.47; p value = 0.023). While FOXP3 has moderate correlation with only LMP1 (ρ = 0.58; p value = 0.004). No correlation was found between all the markers tested here with GTVn. Discussion We found larger primary nasopharyngeal tumor was associated with higher CD8 marker. This was thought due to the presence of abundance CD8 T cells in the nasopharynx, but those abundance CD8 T cells were suspected to be dysfunctional. The nasopharyngeal cancer was also known to upregulate chemokines that could recruit T regulatory FOXP3 cells. Furthermore, T regulatory FOXP3 cells differentiation was induced through several pathways which was triggered by EBNA1. The correlation found in this study could guide further study to understand nasopharyngeal carcinogenesis and the relationship with our immune system.

Defining Biochemical Cure After Low Dose Rate Prostate Brachytherapy: External Validation of 4-year Prostate-specific Antigen Nadir as a Predictor of 10- and 15-year Disease-free Survival. Clin Oncol (R Coll Radiol) 2021; 34:42-49. [PMID: 34848134 DOI: 10.1016/j.clon.2021.11.009] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/11/2021] [Revised: 10/06/2021] [Accepted: 11/10/2021] [Indexed: 11/03/2022]
Abstract
AIMS To externally validate a proposed biochemical definition of cure following low dose rate (LDR) brachytherapy for prostate cancer - 4-year post-implant prostate-specific antigen (PSA) ≤0.2 ng/ml - in a UK population, and report the long-term (10- and 15-year) outcomes for patients stratified by National Comprehensive Cancer Network (NCCN) risk groups, through analysis of a large, prospectively collected, single-centre database. MATERIALS AND METHODS All patients treated with LDR brachytherapy for prostate cancer at a single UK centre between 2001 and November 2020 (n = 1142) were eligible; 632 patients met the inclusion criteria for the analysis. The primary end point was disease-free survival (DFS), defined as freedom from clinical, radiological or PSA progression requiring androgen deprivation therapy. Four-year PSA was categorised as ≤0.2, >0.2 to ≤0.5, >0.5 to ≤1.0 and >1.0 ng/ml. Kaplan-Meier analysis to 15 years was undertaken for each group, and sensitivity and specificity of 4-year PSA as a surrogate for long-term cure were calculated. Kaplan-Meier analysis to 15 years was repeated, stratifying patients by NCCN risk groups. RESULTS The median cohort age was 63 years; the median follow-up was 9.1 years (range 3.5-18.7). In total, 248 patients were available for analysis at year 10, 46 at year 15. Sixty-four patients (10.1%) relapsed during the study period. The 10-year DFS for 4-year PSA categories ≤0.2, >0.2 to ≤0.5, >0.5 to ≤1.0 and >1.0 ng/ml (95% confidence intervals) were 97.5% (95.4-99.6), 89.0% (82.4-96.1), 81.5% (70.5-94.2) and 41.8% (29.7-58.9), respectively. The 10-year DFS results for NCCN low, favourable-intermediate and unfavourable-intermediate risk disease were 93.1% (89.6-96.7), 92.1% (87.6-96.9) and 75.9% (67.8-84.9), respectively. CONCLUSIONS Patients with 4-year PSA ≤0.2 ng/ml may be considered cured, and could be discharged to general practitioner follow-up. LDR brachytherapy is an excellent treatment option for patients with low and favourable-intermediate risk prostate cancer, but those with unfavourable-intermediate risk disease should be considered for treatment intensification strategies.

Prognostic value of PSA bounce after definitive radiotherapy revisited. Int J Clin Oncol 2021; 27:411-417. [PMID: 34677737 DOI: 10.1007/s10147-021-02053-0] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/22/2021] [Accepted: 10/07/2021] [Indexed: 10/20/2022]
Abstract
BACKGROUND Prostate-specific antigen (PSA) bounce after definitive radiotherapy has been reported as a predictor of improved biochemical recurrence-free survival (BCRFS). We revisited this phenomenon to confirm its clinical impact on oncological outcomes in patients with long-term follow-up who were free of biochemical recurrence (BCR) at least 3 years after treatment. MATERIALS AND METHODS A total of 541 patients with localized, intermediate-risk prostate cancer underwent low-dose rate brachytherapy with iodine-125 seeds with or without supplemental external beam radiotherapy in combination. Neoadjuvant hormonal therapy was administered to 273 patients (50.5%) with a median duration of 3 months (range 1-108 months). PSA bounce was defined as ≥ 0.2 ng/ml increase above the interval PSA nadir, followed by a decrease below that value. RESULTS The median age was 69 years (range 49-90 years). The median follow-up duration was 102 months (range 36-205 months). One-hundred and fifty patients (27.7%) had PSA bounce with a median magnitude of 0.47 ng/ml (range 0.2-3.19 ng/ml). Age was significantly associated with the occurrence of PSA bounce [age: hazard ratio (HR) 0.95, 95% confidence interval (CI) 0.93-0.98]. It was found to be independently associated with a decreased risk for BCR (HR 0.29; 95% CI 0.12-0.69) and clinical progression (HR 0.44; 95% CI 0.95-0.98). CONCLUSION PSA bounce indicated a favorable BCRFS and clinical progression-free survival in patients who had been free of BCR for at least 3 years after definitive radiotherapy.

Abstract
BACKGROUND Physician prescribing patterns surrounding the use of testosterone therapy (TTh) in men with a history of prostate cancer (CaP) is not well described. AIM To characterize the demographics and usage patterns of testosterone therapy in men with a history of prostate cancer in the United States. METHODS This was a retrospective review using Optum's De-identified Clinformatics Data Mart database. Administrative diagnosis, procedural, pharmacy, and laboratory codes were used to identify male subjects 40 years and older with prostate cancer treated with surgery or radiation between 2003 and 2018 who went on to receive TTh. Demographic and clinical factors are identified. Temporal trends in TTh usage were reported. OUTCOMES The main outcomes were rates of testosterone prescriptions in men with treated prostate cancer and associated laboratory values such as Prostate Specific Antigen (PSA) and testosterone levels before TTh. RESULTS 126,374 men completed treatment for CaP during the study period (42,515 surgery, 75,186 radiation, 8,673 both). Of these, 3,074 men (2.4%) received testosterone after CaP treatment. Men who received testosterone were younger, more likely to have erectile dysfunction, depressive disorder, and lower pretreatment PSA values compared to men who did not receive. Median PSA levels before TTh initiation were 0 - 0.2 depending on CaP treatment modality and median total testosterone level was <300 ng/dL. TTh began an average of 1.5 years after radical prostatectomy and 2.6 years after radiation treatment. We observed an increase in TTh after CaP from the beginning of the study period until it peaked in 2013 at 4.9%. After 2013, rates decreased annually until a plateau of approximately 1.8% of men. Approximately a third of men did not have testosterone labs checked before initiation of TTh. CLINICAL IMPLICATIONS These findings provide insight into trends in testosterone prescriptions in men after prostate cancer treatment and may aid in clinical decision-making, as well as areas for improvement in cancer survivorship care. STRENGTHS AND LIMITATIONS Strengths include the large sample size, length of data coverage, and real-world analysis of testosterone prescribing patterns across the United States. Limitations include the reliance on insurance claims data, the retrospective study design, and lack of additional relevant clinical variables that may impact decision making regarding TTh. CONCLUSION National trends in testosterone prescriptions for men with treated prostate cancer suggest that many men are treated with TTh after prostate cancer therapy with patterns of indications and monitoring consistent with the general population.

Prognostic value of PSA bounce in prostate cancer following definitive radiation therapy: a systematic review and meta-analysis. Prostate Cancer Prostatic Dis 2021; 24:976-985.

Abstract
BACKGROUND The prognostic significance of PSA bounce following definitive radiation therapy remains controversial. To develop a sense of current opinion in this area, we performed a systematic search of the literature based on the Preferred Reporting Items for Systematic Reviews and Meta-Analyses. METHODS In January 2021, we systematically searched PubMed, the Cochrane library, and Scopus for studies that compared patients who had localized prostate cancer with or without PSA bounce after definitive radiation therapy. Our objective was to evaluate the association of PSA bounce with biochemical recurrence-free survival, metastatic-free survival, cancer-specific survival, and overall survival, using multivariate Cox regression analysis. RESULTS A total of 8881 patients in 10 studies matched the selection criteria for the systematic review and meta-analysis. The number of patients with PSA bounce accounted for 2706 of all 8881 patients (30.5%). PSA bounce was associated with better biochemical recurrence-free survival after definitive radiation therapy (pooled HR: 0.62, 95% CI: 0.54-0.71). Subgroup analyses also showed that PSA bounce was independently associated with decreased risk for biochemical recurrence-free survival in prostate cancer patients treated with low dose rate brachytherapy alone (pooled HR: 0.38, 95% CI: 0.27-0.55) and external beam radiotherapy alone (pooled HR: 0.71, 95% CI: 0.57-0.87). CONCLUSIONS This meta-analysis indicated that PSA bounce after definitive radiation therapy is related to improved outcome in terms of biochemical failure in prostate cancer patients.
