[PMID: 38523903 PMCID: PMC10960082 DOI: 10.1016/j.prnil.2023.09.004] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/17/2023] [Revised: 09/20/2023] [Accepted: 09/25/2023] [Indexed: 03/26/2024] Open
Abstract
Background Despite longer lifespans, guidelines for prostate cancer treatment recommend surgery for those with over 10 years of life expectancy, potentially leaving older patients undertreated. This study examines the outcomes of radical prostatectomy (RP) in a large cohort of men older than 75 years. Materials and methods We retrospectively analyzed 636 patients from a pool of 4,500 RP cases at a single tertiary institution from 2004 to 2022. Patients younger than 75 years or with incomplete records were excluded. Baseline clinical variables, including PSA and biopsy grade group (GG), as well as postoperative pathology and oncological outcomes, were assessed. Achievement of continence based on no pads and ≤1 pad at last follow-up were evaluated. Results Mean age and PSA were 76.4 years and 15.3 ng/ml, respectively. At biopsy, GG1 and 2 were found in 18.1% and 31.5%, respectively, with 28.5% harboring GG4-5 tumors. After RP, 41.5% had GG upgrade compared to biopsy results, with 46.5% with ≥pT3 tumors. In a mean follow-up of 41.5 months, 82.3% were able to attain total continence of 0 pads, and 89.5% used ≤1 pads at the last follow-up. Overall and cancer-specific mortality was observed in 4.3% and 0.9%, respectively, and biochemical recurrence (BCR) occurred in 20.3% after a median of 154 months. At multivariate analysis, age was not a significant factor for BCR, whereas preoperative PSA, biopsy GG, margin positivity, and lymph node invasion were significant. Conclusion RP is feasible in men older than 75 years with decent oncological outcome, with absolute age insignificant within this age group. Risk of undertreatment should be acknowledged, and definite treatment must be considered.

Analysis of trend in the role of national and regional hubs in prostatectomy after prostate cancer diagnosis in the past 5 years: A nationwide population-based study. Investig Clin Urol 2024; 65:124-131. [PMID: 38454821 PMCID: PMC10925729 DOI: 10.4111/icu.20230333] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/04/2023] [Revised: 11/11/2023] [Accepted: 12/29/2023] [Indexed: 03/09/2024] Open
Abstract
PURPOSE The regions where patients diagnosed with prostate cancer by biopsy receive prostatectomy are divided into national hub and regional hubs, and to confirm the change in the role of regional hubs compared to national hub. MATERIALS AND METHODS Data from July 2013 to June 2017 encompassing 218,155 patients aged ≥18 years diagnosed with prostate cancer were analyzed using the Health Insurance Review & Assessment Service database. The degree of patient outflow was assessed by dividing the regional diagnosis-to-surgery ratio with the national ratio for each year. Based on this ratio, national and regional hubs were determined. RESULTS Seoul consistently maintained a patient influx with a ratio above 1.6. Busan and Gyeonggi consistently exceeded 0.9, while Ulsan and Daegu steadily increased, exceeding 1.0 between 2015 and 2016. Jeonnam province also consistently maintained the ratio above 0.7. Jeju, Daejeon, Gangwon, and Incheon remained below 0.5, indicative of substantial patient outflows, whereas Gwangju and Gyeongbuk had the highest patient outflows with ratios below 0.15. Therefore, Seoul was designated as a national hub, whereas Busan, Gyeonggi, Ulsan, Daegu, and Jeonnam were classified as regional hubs. Jeju, Daejeon, Gangwon, and Incheon were the dominant outflow areas, while Gwangju and Gyeongbuk were the highest outflow areas. CONCLUSIONS Seoul, as the national hub for prostate cancer surgery, operated on 1.76 times more patients than any other region during 2013-2017. Busan, Gyeonggi, Ulsan, Daegu, and Jeonnam functioned as regional hubs, but approximately 10%-20% of patients sought treatment at national hubs.

World J Mens Health 2024; 42:237-244. [PMID: 38171378 PMCID: PMC10782121 DOI: 10.5534/wjmh.230119] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/26/2023] [Revised: 08/24/2023] [Accepted: 09/01/2023] [Indexed: 01/05/2024] Open
Abstract
PURPOSE Patients with cancer have a high risk of depression. However, a few studies have assessed differences in the incidence of depression among patients with prostate cancer (PC) based on whether they received radiotherapy (RTx) or surgical treatment. MATERIALS AND METHODS We analyzed data from the National Health Insurance Sharing Service database regarding the entire Korean adult population with PC (n=210,924) between 2007 and 2017. The adjusted hazard ratios (HRs) of depression associated with treatment were estimated using propensity score-matched Cox proportional hazards models and Kaplan-Meier survival analyses. RESULTS Our final cohort comprised 9,456 patients with PC; of which, 8,050 men underwent surgery. During a mean follow-up duration of 7.1 years, 503 (5.3%) patients were newly diagnosed with depression. A significant difference in the incidence of depression was noted between the RTx and surgery groups (RTx vs. surgery: 5.55% vs. 5.28%; p=0.011) in the unmatched cohort. In the matched cohort, older age (≥70 years, HR: 1.596, p<0.001) and poor Charlson comorbidity index scores (HR: 1.232, p=0.039) were correlated with the risk of depression. In addition, the adjusted HR for depression in the surgery group was 0.843 (p=0.221) compared with that in the RTx group. Kaplan-Meier analyses revealed that no significant difference in the cumulative probability of persistent depression was detected between the RTx and surgery groups in matched cohort (p=0.3386). CONCLUSIONS In this nationwide population-based study, no significant differences in the risk of depression were observed between the surgical and RTx groups.

Jung J, Bae GH, Kim JH, Kim J. Outcomes of prostate cancer patients after robot-assisted radical prostatectomy compared with open radical prostatectomy in Korea. Sci Rep 2023; 13:7851. [PMID: 37188739 DOI: 10.1038/s41598-023-34864-8] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/02/2022] [Accepted: 05/09/2023] [Indexed: 05/17/2023] Open
Abstract
Limited evidence exists regarding the value of robot-assisted radical prostatectomy (RARP) in promoting health outcomes in patients with prostate cancer (PCa) in Korea, prompting a study to determine its clinical impact. The study included 15,501 patients with PCa who underwent RARP (n = 12,268) or radical prostatectomy (RP) (n = 3,233) between 2009 and 2017. The outcomes were compared using a Cox proportional hazards model after propensity score matching. Hazard ratios of all-cause overall mortality after RARP compared to that after RP within 3 and 12 months were (6.72, 2.00-22.63, p = 0.002) and (5.55, 3.31-9.31, p < 0.0001), respectively. The RARP group in four hospitals with the largest PCa surgery volume during the study period had worse percentile deaths than the total RARP patients within 3- (1.6% vs. 0.63%) and 12-month post-op (6.76% vs. 2.92%). The RARP group showed specific surgical complications, like pneumonia and renal failure, more than the RP group. A significantly higher short-term mortality and only modestly lower surgical complications occurred in RARP than RP group. RARP performance status may not be superior to that of RP as previously reported and perceived, possibly due to increased robotic surgery in the elderly. More meticulous measures are needed for robotic surgery in the elderly.

Current treatment patterns within 1 year after prostate cancer diagnosis in Korean patients over 75 years old: a retrospective multicenter study. Prostate Int 2023; 11:34-39. [PMID: 36910903 PMCID: PMC9995689 DOI: 10.1016/j.prnil.2022.08.003] [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: 06/22/2022] [Revised: 08/17/2022] [Accepted: 08/22/2022] [Indexed: 11/17/2022] Open
Abstract
Background We aimed to evaluate the current status of first-line treatment options for prostate cancer in patients aged ≥75 years in Korea. Materials and methods The study included 873 patients diagnosed with biopsy-proven prostate cancer at 5 institutions in Korea from January 2009 to December 2018. Inclusion criteria were aged ≥75 years at diagnosis, prostate biopsy with ≥12 cores, and follow-up period ≥1 year. Clinical data were retrospectively collected from electronic medical records. Results Primary treatment for prostate cancer in patients aged ≥75 years included androgen deprivation therapy (ADT) (n = 614), radical prostatectomy (RP) (n = 114), and radiation therapy (n = 62). Among patients with RP, nine patients received ADT before RP. The RP group was younger with better Eastern Cooperative Oncology Group Performance Status (ECOG PS), lower initial prostate-specific antigen (PSA), Gleason score (GS), max percent positive cores, less positive cores, and less advanced clinical Tumor Node Metastasis (TNM) stage compared with the ADT group. Multivariate analysis showed that age, ECOG PS, and PSA were independent prognostic factors for RP. When the ADT group was classified by therapeutic regimens, the most common therapeutic regimen was maximal androgen blockade (MAB) (n = 571), and leuprolide + bicalutamide (n = 330) was the most common MAB regimen. Multivariate analysis for secondary treatment showed that age, ECOG PS, GS, and clinical N1 or M1 stage were independent predictive factors. Enzalutamide was the most preferred treatment for tertiary treatment. Conclusion In patients with prostate cancer aged ≥75 years, the most common treatment option was MAB, and the leuprolide + bicalutamide was the most common MAB regimen. Age, ECOG PS, and PSA are the useful indicators of surgical treatment, which increased during the study period. Younger patients with high GS and advanced clinical stage were more likely to undergo secondary treatment.

Chae J, Choi Y, Cho SJ. Changes in Patterns of Radical Prostatectomy due to Diffusion of Robotic Surgical System: A Nationwide Study Using Health Insurance Claims Data. Yonsei Med J 2021; 62:1155-1161. [PMID: 34816646 PMCID: PMC8612857 DOI: 10.3349/ymj.2021.62.12.1155] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/16/2021] [Revised: 09/23/2021] [Accepted: 09/29/2021] [Indexed: 11/27/2022] Open
Abstract
PURPOSE This study analyzed the changes in the number of surgeries and surgical patterns due to the adoption and diffusion of new medical technology while focusing on radical prostatectomy. MATERIALS AND METHODS Medical equipment status report data and the National Health Insurance claims data from 2007 to 2019 were used. A total of 62798 radical prostatectomies from 135 medical facilities were analyzed. Radical prostatectomy was classified into open radical prostatectomy (ORP), laparoscopic radical prostatectomy (LRP), and robot-assisted laparoscopic radical prostatectomy (RARP) using the fee schedule codes. A linear mixed model was used to determine whether the adoption of a robotic surgical system had an effect on the number of surgeries and surgical patterns after adjusting for medical characteristics. RESULTS The number of radical prostatectomies performed in Korea increased from 1756 in 2007 to 8475 in 2019. During this period, the proportion of RARP in total surgery increased from 17.5% to 74.3%. The mean number of surgeries at medical facilities adopting the robotic surgical system was 128.3, which was higher compared to 18.5 cases in medical facilities that did not adopt it. The adoption of a robotic surgical system increased the number of radical prostatectomy surgeries by 12.1 cases and the RARP share by 47.2% in a linear mixed model. CONCLUSION The adoption and diffusion of robotic surgical systems in Korea increased the number of surgeries as well as the share of robotic surgery. It is necessary to manage a technology that is widely used in a state where its clinical effectiveness is uncertain.

Population-wide impacts of aspirin, statins, and metformin use on prostate cancer incidence and mortality. Sci Rep 2021; 11:16171. [PMID: 34373584 PMCID: PMC8352896 DOI: 10.1038/s41598-021-95764-3] [Citation(s) in RCA: 6] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/08/2020] [Accepted: 07/29/2021] [Indexed: 12/24/2022] Open
Abstract
We evaluated the association between aspirin, statins, and metformin use and prostate cancer (PC) incidence and mortality using a large population-based dataset. 388,760 men who participated in national health screening program in Korea during 2002–2003 were observed from 2004 to 2013. Hazard ratios of aspirin, statins, and metformin use for PC incidence and PC mortality were calculated with adjustment for simultaneous drug use. Cumulative use of each drug was inserted as time-dependent variable with 2-year time windows. Aspirin use ≥ 1.5 year (per 2-year) was associated with borderline decrease in PC mortality when compared to non-users (adjusted hazard ratio [aHR] 0.71, 95% confidence interval [CI] 0.50–1.02). Statins use was not associated with either PC incidence or PC mortality. Metformin ever-use was associated with decreased PC incidence compared with non-diabetics (aHR 0.86, 95% CI 0.77–0.96). Diabetics who were not using metformin or using low cumulative doses had higher PC mortality than non-diabetics (aHR 2.01, 95% CI 1.44–2.81, and aHR 1.70, 95% CI 1.07–2.69, respectively). However, subjects with higher cumulative doses of metformin did not show increased PC mortality. In conclusion, metformin use was associated with lower PC incidence. Use of aspirin and that of metformin among diabetic patients were associated with lower PC mortality.

Abstract
Prostate cancer is a global health problem, but incidence varies considerably across different continents. Asia is traditionally considered a low-incidence area, but the incidence and mortality of prostate cancer have rapidly increased across the continent. Substantial differences in epidemiological features have been observed among different Asian regions, and incidence, as well as mortality-to-incidence ratio, is associated with the human development index. Prostate cancer mortality decreased in Japan and Israel from 2007 to 2016, but mortality has increased in Thailand, Kyrgyzstan and Uzbekistan over the same period. Genomic analyses have shown a low prevalence of ERG oncoprotein in the East Asian population, alongside a low rate of PTEN loss, high CHD1 enrichments and high FOXA1 alterations. Contributions from single-nucleotide polymorphisms to prostate cancer risk vary with ethnicity, but germline mutation rates of DNA damage repair genes in metastatic prostate cancer are comparable in Chinese and white patients from the USA and UK. Pharmacogenomic features of testosterone metabolism might contribute to disparities seen in the response to androgen deprivation between East Asian men and white American and European men. Overall, considerable diversity in epidemiology and genomics of prostate cancer across Asia defines disease characteristics in these populations, but studies in this area are under-represented in the literature. Taking into account this intracontinental and intercontinental heterogeneity, translational studies are required in order to develop ethnicity-specific treatment strategies.

Influence of repeated prostate-specific antigen screening on treatment pattern in a country with a limited social perception of prostate cancer: Korean national wide observational study. Investig Clin Urol 2021; 62:282-289.

Abstract
Purpose To investigate the real-world prevalence of repeated prostate-specific antigen (PSA) screening in Korea and its influence on the treatment pattern of the prostate cancer (PCa) over the last decade, during which PCa has become the 3rd most popular male cancer and PSA test has gained minimal social interest. Materials and Methods From Korean National Health Insurance Service data, men with newly diagnosed PCa from 2008 through 2016 were identified, then the treatment modalities between the repeated PSA screening (defined as at least three PSA tests during minimal 2 years before registration) and non-screening groups (when the first PSA test was performed within 3 months before registration) were compared. Results Among 73,280 men with PCa, only 27.7% met the criteria for screening. In contrast with the continuous increase in the screening population from 334 men in 2008 to 5,049 men in 2016, the non-screening population remained low at 1,543 men in 2008 and 1,819 men in 2016 (p<0.001). During these periods, more patients underwent local therapy (prostatectomy or radiation) in the screening population compared to their non-screened counterparts (59.8% vs. 46.7%, p<0.001), and fewer patients underwent systemic therapy (chemotherapy or hormone) (40.2% vs. 53.3%, p<0.001). Multivariate analysis adjusting other variables demonstrated 2-fold higher mortality in the non-screening population (hazard ratio=2.050, p<0.0001). Conclusions Among the patients newly diagnosed with PCa, only about a quarter received repeated PSA screening. However, these patients showed a higher probability of local treatment than the systemic one in comparison with non-screened counterparts.

Cancer Epidemiol Biomarkers Prev 2020; 30:326-334. [PMID: 33187966 DOI: 10.1158/1055-9965.epi-20-1084] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/16/2020] [Revised: 09/16/2020] [Accepted: 11/09/2020] [Indexed: 12/24/2022] Open
Abstract
BACKGROUND Conditional relative survival (CRS) and competing mortality are important survivorship issues after cancer treatment. We aimed to investigate them among patients with prostate cancer treated by various modalities. METHODS Using a nationwide population-based database, we calculated 5-year CRS conditioned on 1 through 5 years survival after diagnosis. These rates were stratified by age, sex, socioeconomic status, comorbidities, and treatment received. Cause of death and estimated cause-specific mortality were also described and considered with competing risks. RESULTS A total of 81,773 patients newly diagnosed with primary prostate cancer from 2007 to 2013 were identified. The 5-year CRS was 81.1% at baseline, but increased gradually up to 95.4% at 4 years and exceeded 100% at 5 years after diagnosis, suggesting no excess mortality compared with the general population. However, this pattern differed by treatment received. Patients who underwent androgen deprivation therapy showed 5-year CRS of only 88.4% at 5 years after diagnosis, implying persistent excess mortality. Prostate cancer constituted around one-third of deaths, while other cancers were the main cause of death within <2 years after diagnosis. Noncancer-related deaths, including cardiovascular disease and respiratory disease, increased with time since diagnosis. CONCLUSIONS CRS rates for patients with prostate cancer improved over time and exceeded that of the general population at 5 years. Other cancers were the main cause of death in the earlier survivorship phase, and deaths from noncancer causes gradually increased over time. IMPACT Our findings will help patients and clinicians make evidence-based decisions on the basis of a patient's dynamic risk profile.

Abstract
In this study using national health insurance data, we investigated the risk of ischemic heart disease (IHD) and stroke among prostate cancer (PC) survivors compared with the general population, as well as the risk of cardiovascular disease (CVD) according to primary treatment. A total of 48,298 PC patients diagnosed from 2007 to 2013 were included and matched to non-cancer controls. Compared to the general population, PC survivors had a slightly lower risk of IHD (adjusted hazard ratio [aHR] = 0.89, 95% confidence interval [CI] 0.83–0.96) or stroke (aHR 0.90, 95% CI 0.87–0.95). Especially, survivors who underwent surgery had lower risks of IHD (aHR 0.70, 95% CI 0.61–0.80) or stroke (aHR 0.73, 95% CI 0.67–0.81). Compared to survivors in the active surveillance/watchful waiting group, the androgen deprivation therapy (ADT) group had a significantly greater risk of stroke (aHR 1.16, 95% CI 1.02–1.32), but the IHD risk was not significantly elevated (aHR 1.06, 95% CI 0.88–1.29). In conclusion, PC survivors had a slightly lower risk of CVD compared to the general population, which was attributable to self-selection for PSA screening, specifically in the surgery-only group. CVD risk was dependent on treatment received, and attention should be given to patients who receive ADT.

[PMID: 32360240 DOI: 10.1016/j.currproblcancer.2020.100578] [Citation(s) in RCA: 12] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/14/2020] [Revised: 03/03/2020] [Accepted: 03/17/2020] [Indexed: 10/24/2022]
Abstract
OBJECTIVES To investigate the effects of prostate cancer (PC) and various treatment modalities for PC, specifically androgen deprivation therapy (ADT), on the risk of dementia and dementia subtypes in PC survivors. MATERIAL AND METHODS A total of 51,252 patients newly diagnosed with PC from 2007 to 2013, who had no prior diagnosis of cancer or dementia, were included and matched with 209,659 non-cancer control. The screening subset was comprised of subjects who participated in a health screening program. We used Cox proportional hazards model to estimate the relative risk of dementia and dementia subtypes according to the primary treatment for the PC. RESULTS Compared to non-PC matched controls, PC survivors showed slightly higher risk for dementia and Alzheimer disease (AD) only in the screening cohort. While PC survivors who underwent ADT were higher risk for dementia and AD, patients who underwent surgery were lower risk for dementia and AD, compared to the non-cancer population. Compared to surgery, ADT, surgery + ADT, and active surveillance/watchful waiting showed a significantly elevated risk for dementia. CONCLUSION PC survivors had slightly higher risk for dementia compared to non-PC controls, which might be related to the screening effects of PC. The risk for dementia was most prominent among PC patients who underwent ADT, followed by patients who underwent AS/WW, and those who underwent surgery + ADT. This finding suggests that individualized ADT strategies that consider the survival benefit and underlying dementia risk in PC survivors are necessary.

Abstract
Purpose To report an initial single-surgeon experience with single-port robot-assisted radical prostatectomy (SP-RARP) using the da Vinci SP surgical system (Intuitive Surgical, USA). Materials and Methods Between December 2018 and October 2019, a single surgeon performed SP-RARP in 20 patients with prostate cancer. SP-RARP was performed using the conventional approach through an umbilical port with a GelPOINT access system (Applied Medical, USA) and an additional assist port. During surgery, the camera was placed in the 6- or 12-o'clock position, and a traction arm was placed in the counterpart position for upward or downward traction. Clinicopathologic data, perioperative data, and short-term surgical outcomes were analyzed. Results Of 20 patients, 45% of patients had pT3 or greater disease and 45% had Gleason grade 4 to 5, respectively. In 11 patients that underwent lymph node dissection, the median number of lymph nodes removed was 19 (interquartile range [IQR], 14–22). Median operative time was 245 minutes (IQR, 200–255), and median console time was 190 minutes (IQR, 165–210). Median blood loss was 200 mL (IQR, 150–300 mL), and there were no intraoperative complications or open conversion. In 10 patients with a follow-up period longer than 3 months, one patient experienced biochemical recurrence, and all patients required 0 to 1 pads per day. Of seven patients that were potent before surgery, four recovered erectile function sufficient for intercourse. Conclusions Our report shows the safety and feasibility of SP-RARP, and that the associated surgical outcomes with short-term follow-up are satisfactory.

Variation in radiotherapy patterns of care in the radical treatment of South Australian men with non-metastatic prostate cancer between 2005-2015. Radiother Oncol 2020; 145:138-145. [PMID: 31978853 DOI: 10.1016/j.radonc.2019.12.022] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/20/2019] [Revised: 12/16/2019] [Accepted: 12/22/2019] [Indexed: 11/24/2022]
Abstract
BACKGROUND AND PURPOSE To investigate associations between socio-demographic characteristics and radiotherapy patterns of care in non-metastatic prostate cancer [nmPCa] in South Australia [SA] between 2005-2015 and document practice patterns over time. MATERIALS AND METHODS Men with nmPCa receiving primary curative radiotherapy were identified from SA Prostate Cancer Clinical Outcomes Collaborative database. Adjuvant, salvage and palliative therapies were excluded. Associations between socio-demographic factors (age, residence, socio-economic status, diagnostic period) and radiotherapy mode (external beam radiotherapy [EBRT] vs. brachytherapy [BT]) and technique (low-dose-rate vs. high-dose-rate brachytherapy) were investigated using multivariable logistic regression with separate models for clinical risk categories. RESULTS Of the 1874 men who underwent primary RT, 80% received EBRT and 20% BT. For low and intermediate risk disease, likelihood of receiving EBRT was higher among older men (ORlow = 3.08; 95% CI 1.82-5.22 and ORintermediate = 3.48; 2.28-5.31 for 65-74 yrs vs. <65 yrs) and lower among regional/remote compared with metropolitan residents (ORlow = 0.34; 0.17-0.67 and ORintermediate = 0.57; 0.34-0.94). For intermediate and high risk disease, more recent diagnosis was associated with decreased likelihood of EBRT (ORintermediate = 0.22; 95% CI 0.15-0.33 and ORhigh = 0.50; 0.29-0.88, respectively). Among men receiving BT, low-dose-rate BT use decreased over time for low (OR = 0.19; 0.04-0.89) and intermediate risk disease (OR = 0.32; 0.12-0.84). Dose escalation and intensity modulation for EBRT increased after 2010. CONCLUSION Over the last decade substantial changes in RT for nmPCa were observed. Older age and more remote residence may be barriers to accessing specific types of RT. Further research to understand how these factors affect access is warranted to improve service provision.

Abstract
Purpose To determine prognostic significance of lymphovascular invasion (LVI) in prostate cancer patients who underwent adjuvant or salvage postoperative radiotherapy (PORT) after radical prostatectomy (RP) Materials and Methods A total of 168 patients with prostate cancer received PORT after RP, with a follow-up of ≥12 months. Biochemical failure after PORT was defined as prostate-specific antigen (PSA) ≥0.2 ng/mL after PORT or initiation of androgen deprivation therapy (ADT) for increasing PSA levels regardless of the value. We analyzed the clinical outcomes including survivals, failure patterns, and prognostic factors affecting the outcomes. Results In total, 120 patients (71.4%) received salvage PORT after PSA levels were >0.2 ng/mL or owing to clinical failure. The 5-year biochemical failure-free survival (BCFFS), clinical failure-free survival (CFFS), distant metastasis-free survival (DMFS), overall survival, and cause-specific survival rates were 78.3%, 94.3%, 95.0%, 95.8%, and 97.3%, respectively, during a follow-up range of 12–157 months (median: 64 months) after PORT. On multivariate analysis, PSA level of ≤1.0 ng/mL at the time of receiving PORT predicted favorable BCFFS, CFFS, and DMFS. LVI predicted worse CFFS (p = 0.004) and DMFS (p = 0.015). Concurrent and/or adjuvant ADT resulted in favorable prognosis for BCFFS (p < 0.001) and CFFS (p = 0.017). Conclusion For patients with adverse pathologic findings, PORT should be initiated as early as possible after continence recovery after RP. Even after administering PORT, LVI was an unfavorable predictive factor, and further intensive adjuvant therapy should be considered for these patients.

Abstract
BACKGROUND A complete enumeration study was conducted to evaluate trends in national practice patterns and direct medical costs for prostate cancer (PCa) in Korea over a 10-year retrospective period using data from the Korean National Health Insurance Service. METHODS Reimbursement records for 874,924 patients diagnosed between 2002 and 2014 with primary PCa according to the International Classification of Disease (ICD) 10th revision code C61 were accessed. To assess direct medical costs for patients newly diagnosed after 2005, data from 68,596 patients managed between January 2005 and 31 December 2014 were evaluated. RESULTS From 2005 to 2014, the total number of PCa patients showed a 2.6-fold increase. Surgery and androgen deprivation therapy were the most common first-line treatment, alone or within the context of combined therapy. Surgery as a monotherapy was performed in 23.5% of patients in 2005, and in 39.4% of patients in 2014. From 2008, the rate of robot-assisted RP rose sharply, showing a similar rate to open RP in 2014. Average total treatment costs in the 12 months post-diagnosis were around 10 million Korean won. Average annual treatment costs thereafter were around 5 million Korean won. Out-of-pocket expenditure was highest in the first year post-diagnosis, and ranged from 12 to 17% thereafter. CONCLUSIONS Between 2005 and 2014, a substantial change was observed in the national practice pattern for PCa in Korea. The present data provide a reliable overview of treatment patterns and medical costs for PCa in Korea.

Abstract
PURPOSE Combined androgen blockade (CAB) and luteinizing hormone-releasing hormone (LHRH) agonist monotherapy are commonly used in androgen deprivation therapy (ADT). In this randomized clinical trial, we aimed to compare the two methods of ADT in terms of quality of life (QOL). METHODS Eighty patients who underwent primary ADT for newly diagnosed prostate cancer were randomly assigned to CAB group (Group 1) and LHRH agonist monotherapy group (Group 2). Leuprolide and anti-androgen (bicalutamide 50 mg) were used to minimize the confounding effects caused by medication. QOL was evaluated at baseline, 3 months and 6 months post-ADT using validated EORTC QLQ-C30, PR25, and depression questionnaires. A difference of > 10 points in the EORTC domain scores was defined as 'clinically significant'. RESULTS In the baseline characteristics, there was no significant difference between the two groups. At 3 months after ADT, Group 1 had significantly lower pain scores than Group 2 (p = 0.004), while Group 1 had significantly poorer diarrhea symptom score than Group 2, without clinical significance (p = 0.047). No significant differences were observed in the C30, PR25 domains, and the depression score at 3 months. At 6 months, the QOL scores of all the groups were similar. CONCLUSIONS There was no difference in the patient's QOL, except that CAB group was associated with significantly better pain relief than LHRH agonist monotherapy at 3 months following ADT, which was not sustained thereafter. Our results suggest that the benefit of prolonged (≥ 3 months) CAB is questionable in terms of patients' QOL.

Abstract
Background: Previous reviews of geographical disparities in the prostate cancer continuum from diagnosis to mortality have identified a consistent pattern of poorer outcomes with increasing residential disadvantage and for rural residents. However, there are no contemporary, systematic reviews summarizing the latest available evidence. Our objective was to systematically review the published international evidence for geographical variations in prostate cancer indicators by residential rurality and disadvantage. Methods: Systematic searches of peer-reviewed articles in English published from 1/1/1998 to 30/06/2018 using PubMed, EMBASE, CINAHL, and Informit databases. Inclusion criteria were: population was adult prostate cancer patients; outcome measure was PSA testing, prostate cancer incidence, stage at diagnosis, access to and use of services, survival, and prostate cancer mortality with quantitative results by residential rurality and/or disadvantage. Studies were critically appraised using a modified Newcastle-Ottawa Scale. Results: Overall 169 studies met the inclusion criteria. Around 50% were assessed as high quality and 50% moderate. Men from disadvantaged areas had consistently lower prostate-specific antigen (PSA) testing and prostate cancer incidence, poorer survival, more advanced disease and a trend toward higher mortality. Although less consistent, predominant patterns by rurality were lower PSA testing, prostate cancer incidence and survival, but higher stage disease and mortality among rural men. Both geographical measures were associated with variations in access and use of prostate cancer-related services for low to high risk disease. Conclusions: This review found substantial evidence that prostate cancer indicators varied by residential location across diverse populations and geographies. While wide variations in study design limited comparisons across studies, our review indicated that internationally, men living in disadvantaged areas, and to a lesser extent more rural areas, face a greater prostate cancer burden. This review highlights the need for a better understanding of the complex social, environmental, and behavioral reasons for these variations, recognizing that, while important, geographical access is not the only issue. Implementing research strategies to help identify these processes and to better understand the central role of disadvantage to variations in health outcome are crucial to inform the development of evidence-based targeted interventions.

Abstract
PURPOSE Radical prostatectomy (RP) is one of main treatments for prostate cancer (Pca). The prevalence of Pca has been decreasing in recent reports. However, no study has reported trends in Pca prevalence or RP rate according to age structural changes. The objective of this study was to investigate trends in Pca prevalence and frequency of RP according to age structural change. MATERIALS AND METHODS We evaluated trends in Pca prevalence and RP rate using National Health Insurance Data from 2005 to 2015. Relationships for Pca prevalence and RP rate with age structural change were also determined. Primary outcomes included trends in Pca prevalence and RP rates according to age groups, comparing those before and after 2011. RESULTS Pca prevalence tended to increase before 2011 and decreased after 2011 in persons in the 60-years age group. RP rate increased pattern before 2011 and decreased after 2011 in age groups of 50s, 60s, and over 70s. Pca prevalence and age structural change showed a significantly positive relationship in all age groups, except for the age group under 40 years. RP rate and age structural change also showed a significantly positive relationship in all age groups. CONCLUSION Age structural change can affect the decreasing trend in Pca prevalence and RP rate in South Korea. Future studies are needed to validate this result.

Health-Related Quality of Life Changes in Prostate Cancer Patients after Radical Prostatectomy: A Longitudinal Cohort Study. Cancer Res Treat 2018; 51:556-567. [PMID: 30011984 PMCID: PMC6473266 DOI: 10.4143/crt.2018.221] [Citation(s) in RCA: 9] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/03/2018] [Accepted: 07/13/2018] [Indexed: 12/12/2022] Open
Abstract
Purpose Health-related quality of life (HRQOL) information related to radical prostatectomy (RP) is valuable for prostate cancer (PC) patients needing to make treatment decisions. We aimed to investigate HRQOL change in PC patients who underwent three types of RP (open, laparoscopic, or robotic) and compared their HRQOL with that of general population. Materials and Methods Patients were prospectively recruited between October 2014 and December 2015. European Organization for Research and Treatment of Cancer Quality-of-Life Questionnaire (EORTC QLQ-C30) and PC-specific module (PR25) were administered before surgery (baseline) and at postoperative 3 and 12 months. At each time point, HRQOL was compared, and a difference of 10 out of 0-100 scale was considered clinically significant. Results Among 258 screened patients, 209 (41 open, 63 laparoscopic, and 105 robotic surgeries) were included. Compared to baseline, physical, emotional, and cognitive functioning improved at 12 months. Role functioning worsened at 3 months, but recovered to baseline at 12 months. Pain, insomnia, diarrhea, and financial difficulties also significantly improved at 12 months. Most PR25 scales excluding bowel symptoms deteriorated at 3 months. Urinary symptoms and incontinence aid recovered at 12 months, whereas sexual activity and sexual function remained poor at 12 months. Clinically meaningful differences in HRQOL were not observed according to RP modalities. Compared to the general population, physical and role functioning were significantly lower at 3 months, but recovered by 12 months. Social functioning did not recover. Conclusion Most HRQOL domains showed recovery within 12 months after RP, excluding sexual functioning and social functioning. Our findings may guide patients considering surgical treatment for PC.

J Cancer 2018; 9:1797-1803. [PMID: 29805706 PMCID: PMC5968768 DOI: 10.7150/jca.25113] [Citation(s) in RCA: 10] [Impact Index Per Article: 1.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/23/2018] [Accepted: 03/13/2018] [Indexed: 11/05/2022] Open
Abstract
Objectives: A Patterns of Care Study (PCS) was performed in the largest regional medical center in Zhejiang Province, China. The hospital information system (HIS) was used to evaluate patient characteristics and changes in initial treatment patterns for prostate cancer and to determine recent predominant trends in treatment plans for prostate cancer (PCa) in China. Methods: Men who were newly diagnosed with localized or locally advanced PCa for 2010-2011 and 2016-2017 were identified in the HIS database. Patient characteristics and temporal trends in initial management were assessed, and differences between groups were evaluated for significance using Chi-square and Mann-Whitney U tests. Results: In total, 1792 patients met the study criteria, including 505 and 1287 patients in the 2010-2011 and 2016-2017 samples, respectively. The average age of patients diagnosed in the 2010-2011 PCS survey was 70 years, decreasing to 68 years when the 2016-2017 patients were included (P<0.001). In the 2010-2011 sample, 50.69% of the patients had an initial prostate-specific antigen (PSA) level ≥20 ng/ml. In contrast, the initial PSA level was 4-19.99 ng/ml for 66.67% of the patients in the 2016-2017 sample (P<0.001). Based on National Comprehensive Cancer Network (NCCN) criteria, the percentages of patients in low- and intermediate-risk groups increased from 33.06% to 54.78%; conversely, the percentages in high-risk, very high-risk, and regional (N1) groups decreased to a certain extent (P<0.001). According to European Association of Urology (EAU) criteria, the percentages of patients in low- and intermediate-risk groups increased from 32.07% to 53.69%, yet the percentage in the high-risk group decreased (P<0.001). The use of radical prostatectomy (RP) and radiation therapy (RT) increased from 48.32% to 76.46% and 5.35% to 16.94%, particularly in high-risk and low-risk groups, respectively, whereas the rates of hormone therapy (HT) and active surveillance and observation (AS&O) decreased from 32.28% to 4.27% and from 16.04% to 2.33%, respectively (P<0.001). A similar pattern was observed when patients were stratified by EAU risk group. Conclusions: The results of this real-world study in the largest regional medical center in Zhejiang Province, China, indicate that the predominant characteristics of PCa patients and trends in initial management are changing rapidly. We found the following: (a) a trend toward a decreased age among newly diagnosed patients; (b) a trend toward lower initial PSA levels; (c) a downward trend in risk group classification; (d) a significant increase in the likelihood of receiving RP, particularly in the high-risk group; (e) an increase in the rate of RP, mostly due to use of the Da Vinci robotic system; (f) a significant increase in the likelihood of receiving RT, especially in the low-risk group; and (g) a decrease in HT and AS&O.

Medical Travel among Non-Seoul Residents to Seek Prostate Cancer Treatment in Medical Facilities of Seoul. Cancer Res Treat 2018; 51:53-64. [PMID: 29458236 PMCID: PMC6333968 DOI: 10.4143/crt.2017.468] [Citation(s) in RCA: 7] [Impact Index Per Article: 1.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/04/2017] [Accepted: 02/19/2018] [Indexed: 12/23/2022] Open
Abstract
PURPOSE This study aims to investigate the trend in medical travel by non-Seoul residents to Seoul for treatment of prostate cancer and also to investigate the possible factors affecting the trend. Materials and Methods This study represents a retrospective cohort study using data from theKoreanNationalHealth Insurance System from 2002 to 2015. Annual trends were produced for proportions of patients who traveled according to the age group, economic status and types of treatment. Multiple logistic analysiswas used to determine factors affecting surgeries at medical facilities in Seoul among the non-Seoul residents. RESULTS A total of 68,543 patients were defined as newly diagnosed prostate cancer cohorts from 2005 to 2014. The proportion of patients who traveled to Seoul for treatment, estimated from cases with prostate cancer-related claims, decreased slightly over 9 years (28.0 at 2005 and 27.0 at 2014, p=0.02). The average proportion of medical travelers seeking radical prostatectomy increased slightly but the increase was not statistically significant (43.1 at 2005 and 45.4 at 2014, p=0.26). Income level and performance ofrobot-assisted radical prostatectomy were significant positive factors for medical travel to medical facilities in Seoul. Combined comorbidity diseases and year undergoing surgery were significant negative factors for medical travel to medical facilities in Seoul. CONCLUSION The general trend of patients travelling from outside Seoul for prostate cancer treatment decreased from 2005 to 2014. However, a large proportion of traveling remained irrespective of direct distance from Seoul.

Abstract
Purpose The purpose of this study was to describe treatment patterns of radiotherapy (RT) for prostate cancer in Korea. Materials and Methods A questionnaire about radiation treatment technique and principles in 2013 was sent to 83 radiation oncologists and data from 57 hospitals were collected analyzed to find patterns of RT for prostate cancer patients in Korea. Results The number of patients with prostate cancer treated with definitive RT ranged from 1 to 72 per hospital in 2013. RT doses and target volumes increased according to risk groups but the range of radiation doses was wide (60 to 81.4 Gy) and the fraction size was diverse (1.8 to 5 Gy). Intensity-modulated radiation therapy was used for definitive treatment in 93.8% of hospitals. Hormonal therapy was integrated with radiation for intermediate (63.2%) and high risk patients (77.2%). Adjuvant RT after radical prostatectomy was performed in 46 hospitals (80.7%). Indications of adjuvant RT included positive resection margin, seminal vesicle invasion, and capsular invasion. The total dose for adjuvant RT ranged from 50 to 72 Gy in 24–39 fractions. Salvage RT was delivered with findings of consecutive elevations in prostate-specific antigen (PSA), PSA level over 0.2 ng/mL, or clinical recurrence. The total radiation doses ranged from 50 to 80 Gy with a range of 1.8 to 2.5 Gy per fraction for salvage RT. Conclusion This nationwide patterns of care study suggests that variable radiation techniques and a diverse range of dose fractionation schemes are applied for prostate cancer treatment in Korea. Standard guidelines for RT in prostate cancer need to be developed.

Abstract
Despite rapid increase in incidence of prostate cancer (PC) and PC survivors, there are few studies regarding competing causes of death and time trends in Asian population. We conducted a cohort study of 2% nationwide random sample of Korean National Health Insurance employees. A total of 873 patients who had received active treatments, including surgery, radiation therapy (RT) and androgen deprivation therapy (ADT), for newly diagnosed PC between 2003 and 2010 were included. The cause of death was categorized as PC, other cancers, cardiovascular disease, and other causes. During a median follow-up of 4.75 years, 29.4% (257/873) of the study population died. PC, other cancers, cardiovascular disease, and other causes were responsible for 46.3%, 35.4%, 6.6%, and 11.7%, respectively, of the decedents. Significant differences existed in the cause of death among treatment groups (P < 0.001). Only 20% and 9.5% of surgery and RT group died of PC, whereas 63.9% of ADT group died of PC. Other cancers were responsible for 56%, 74.6% and 17.8% of death in the surgery, RT and ADT group, respectively, while cardiovascular disease accounted for 4%, 6.3%, and 7.1% of death in the treatment groups. Analysis of time trends showed that PC-specific death tended to decrease (from 42.9% in 2003 to 23.1% in 2010), whereas non-PC causes tended to increase over the 8 years. Our results are valuable in overviewing causes of death and time trends in Korean PC patients, and planning future health policy for PC.
