RESUMO
BACKGROUND: In previous large-scale studies conducted through 2010, androgen deprivation therapy (ADT) was the most common initial treatment for prostate cancer patients in Japan. However, recent advancements in treatment technologies have significantly affected the management of prostate cancer in Japan. This study analyzed the trends in initial treatments for prostate cancer based on two nationwide surveys. METHODS: Two Japan-wide multi-institutional surveys, J-CaP2010 and J-CaP2016, were conducted to enroll patients newly histologically diagnosed with prostate cancer in 2010 and 2016-18, respectively. Both surveys included age at diagnosis, initial PSA level, ISUP Grade Group, TNM classification, and initial treatment for prostate cancer. RESULTS: J-CaP2010 included data from 8192 patients across 140 institutions, whereas J-CaP2016 included data from 21 841 patients across 186 institutions. In J-CaP2016, the proportion of radical prostatectomy (RP) and radiation therapy (RT) in the initial treatment increased (from 32% to 36% and 21% to 26%, respectively), whereas the proportion of ADT decreased (from 40% to 29%) compared with those in J-CaP2010. The increase in RP or RT was noticeable in patients aged 75 years and older (from 20% to 38%) and those with high-risk localized cancer (from 58% to 74%) or locally advanced cancer (from 38% to 56%). The proportion of active surveillance or watchful waiting increased in patients with low-risk localized cancer (from 21% to 41%). The proportion of robot-assisted RP within all RPs and the proportion of intensity-modulated RT within all RTs increased remarkably (from 2.3% to 78% and 20% to 50%, respectively). CONCLUSIONS: In Japan, RP and RT have increased as initial treatments for prostate cancer, whereas ADT has decreased. Consequently, RP has emerged as the most commonly selected initial treatment, replacing ADT.
RESUMO
BACKGROUND: Idiopathic pulmonary fibrosis (IPF) is a progressive disease with a poor prognosis. Pulmonary function tests (PFTs) aid in evaluating the disease status of IPF. The clinical significance of oscillometry measurements in interstitial lung diseases has recently been reported. Our previous study showed that respiratory reactance (Xrs) measured by oscillometry reflected disease severity and predicted subsequent lung capacity decline in patients with IPF. However, the direct impact of Xrs on survival needs to be determined, and there are currently no reference values in oscillometry to predict prognosis. Therefore, this study aimed to investigate the association between oscillometry measurements, particularly Xrs, and survival in patients with IPF and to determine the cutoff values of Xrs that predict 3-year survival. METHODS: We analyzed the relationship between the measured values of PFT and oscillometry derived from 178 patients with IPF. Univariate and multivariate Cox proportional hazards analyses were performed to investigate the relationships between clinical indices at the time of the first oscillometry and survival. We performed the time-dependent receiver operating characteristic (ROC) curve analysis to set the optimized cutoff values of Xrs for 3-year survival prediction. We examined the discriminating power of cutoff values of Xrs on survival using the Kaplan-Meier method and the log-rank test. RESULTS: Xrs components, especially in the inspiratory phase (In), significantly correlated with the PFT values. In the multivariate analyses, Xrs (all of reactance at 5 Hz [X5], resonant frequency [Fres], and low-frequency reactance area [ALX] in the inspiratory phase) had a significant impact on survival (X5, p = 0.003; Fres, p = 0.016; ALX, p = 0.003) independent of age, sex, and other prognostic factors derived from the univariate analysis. The area under the ROC curve was 0.765, 0.759, and 0.766 for X5 In, Fres In, and ALX In, with cutoff values determined at - 0.98, 10.67, and 5.32, respectively. We found significant differences in survival after dividing patients using each of the cutoff values of Xrs. CONCLUSIONS: In patients with IPF, Xrs measured by oscillometry significantly impacted survival. We also determined the cutoff values of Xrs to discriminate patients with poor prognoses.

INTRODUCTION: The aim of the study was to examine whether disinfection of bacillus Calmette-Guerin-containing urine with etaprocohol® (ethanol 76.9-81.4 vol % and isopropanol as an additive) is safer than disinfection with sodium hypochlorite. METHOD: In prospective research, safety and efficacy was analyzed in 5 patients in the etaprocohol® disinfection group and 5 patients in the sodium hypochlorite disinfection group. The primary endpoint was the temperature change after disinfection and the secondary endpoint was the unpleasantness of the odor caused by disinfection. Additionally, concentration of gas produced was also examined. Sensory tests were taken from staff who performed urine disinfection and the odor generated by disinfection was evaluated. As a safety protocol, post-BCG-treated urine is cultured to verify the negativity for mycobacteria. RESULTS: Mycobacteria were disinfected in all cases. The temperature rise following disinfection was significantly higher in the sodium hypochlorite group. The sensory test outcomes were significantly worse in the group disinfected with sodium hypochlorite. The concentration of gas generated immediately after disinfection in both groups reached the maximum value and declined quickly. CONCLUSIONS: Disinfection of bacillus Calmette-Guerin-containing urine with etaprocohol® was safer than disinfection with sodium hypochlorite, and an equivalent disinfection effect was achieved.
RESUMO
The real-world benefits of adding androgen-deprivation therapy (ADT) and its optimal duration when combined with current standard high-dose radiation therapy (RT) remain unknown. We aimed to assess the efficacy of and toxicities associated with ADT in the setting of combination with high-dose RT for intermediate-risk (IR) and high-risk (HR) prostate cancer (PCa). This article is a modified and detailed version of the commentary on Clinical Question 8 described in the Japanese Clinical Practice Guidelines for Prostate Cancer (ver. 2023). A qualitative systematic review was performed according to the Minds Guide. All relevant published studies between September 2010 and August 2020, which assessed the outcomes of IR or HR PCa treated with high-dose RT, were screened using two databases (PubMed and ICHUSHI). A total of 41 studies were included in this systematic review, mostly consisting of retrospective studies (N = 34). The evidence basically supports the benefit of adding ADT to high-dose RT to improve tumor control. Regarding IR populations, many studies suggested the existence of a subgroup for which adding ADT had no impact on either overall survival or the BF-free duration. On the other hand, regarding HR populations, several studies suggested the positive impact of adding ADT for ≥1 year on overall survival. Adding ADT increases not only the risk of sexual dysfunction but also that of cardiovascular toxicities or bone fracture. Although the benefit of adding ADT was basically suggested for both IR and HR populations, further investigations are warranted to identify subgroups of patients for whom ADT has no benefit, as well as the appropriate duration of ADT for those who do derive benefit.
RESUMO
OBJECTIVES: We investigated the correlation between surgical outcomes and postoperative urinary continence recovery in robot-assisted radical prostatectomy (RARP). METHODS: Patients who underwent RARP in our institution (n = 195) were included in this study. Preserved urethral length (PUL) was assessed during the procedure. Other outcomes of the surgical procedure were collected from operative records. Kaplan-Meier analysis with log-rank test was used to compare urinary continence recovery rate with the PUL, sparing of the neurovascular bundle (NVB), and other surgical procedures. Univariate and multivariate analyses were performed using Cox proportional hazards model, and p-values of <0.05 were considered significant. RESULTS: Patients with a PUL ≥26 mm had 10.0%, 24.7%, 36.6%, and 89.0% continence recovery rates at 30, 60, 90, and 365 days after surgery, respectively, while patients with a PUL <26 mm had 0%, 17.8%, 26.1%, and 80.9% recovery rates, respectively. Kaplan-Meier curves showed significantly better postoperative urinary continence recovery at 30 days after RARP in patients with a PUL ≥26 mm than those with a PUL <26 mm (p = 0.0028) and in patients with NVB preservation than those with no NVB preservation (p = 0.014). Urinary continence recovery within 30, 60, and 90 days after surgery was 90.6% for patients with a PUL of ≥26 mm and NVB preservation, while only 82.3% for patients with a PUL of <26 mm or no NVB preservation. CONCLUSION: Our results suggest that a PUL ≥26 mm and NVB preservation after RARP correlate with a significantly higher postoperative rate of recovery of urinary continence.

This fourth edition of the Japanese Clinical Practice Guidelines for Prostate Cancer 2023 is compiled. It was revised under the leadership of the Japanese Urological Association, with members selected from multiple academic societies and related organizations (Japan Radiological Society, Japanese Society for Radiation Oncology, the Department of EBM and guidelines, Japan Council for Quality Health Care (Minds), Japanese Society of Pathology, and the patient group (NPO Prostate Cancer Patients Association)), in accordance with the Minds Manual for Guideline Development (2020 ver. 3.0). The most important feature of this revision is the adoption of systematic reviews (SRs) in determining recommendations for 14 clinical questions (CQs). Qualitative SRs for these questions were conducted, and the final recommendations were made based on the results through the votes of 24 members of the guideline development group. Five algorithms based on these results were also created. Contents not covered by the SRs, which are considered textbook material, have been described in the general statement. In the general statement, a literature search for 14 areas was conducted; then, based on the general statement and CQs of the Japanese Clinical Practice Guidelines for Prostate Cancer 2016, the findings revealed after the 2016 guidelines were mainly described. This article provides an overview of these guidelines.
RESUMO
This article is an English translation of the Clinical Practice Guidelines for Upper Tract Urothelial Carcinoma (2nd edition) published in June 2023. The Japanese Urological Association's (JUA) Guidelines Committee on Upper Tract Urothelial Carcinoma (UTUC) created a 2023 update guideline to support clinicians' current evidence-based management of UTUC and to incorporate its recommendations into clinical practice. The new guideline adhered as closely as possible to the Minds Manual for Guideline Development 2020 ver. 3.0. Findings related to epidemiological, pathological, diagnosis, treatment, and follow-up were reviewed. In addition, seven clinical questions (CQs) were set to determine the grade of recommendation and level of evidence. Preconceptions and biases were removed from the preparation process, the overall evidence was evaluated appropriately, and recommendations were made after fully considering the balance between benefits and harms. Although the evidence is still insufficient to be taken up as a CQ, the latest important information is described in seven columns, and clinical issues that should be resolved in the future related to the CQ are described as recommendations for tomorrow. We hope that these guidelines will help medical professionals, patients, and their families involved in the treatment of UTUC in their decision-making, and hope that a critical review of these guidelines will lead to further refinements in the next edition.

OBJECTIVES: To reduce cancer care disparities in people with mental illness, this study aimed to quantify psychiatric care providers' perceptions regarding issues that are insufficiently addressed or difficult to address. METHODS: Psychiatric care providers at 23 psychiatric hospitals in Japan were surveyed using mail questionnaires. Respondents were asked to rate 15 items with four categories related to insufficiencies/difficulties in cancer care for patients with mental illness on a five-point Likert scale. We analyzed the proportion of respondents who answered "insufficient/difficult" for each item. RESULTS: A total of 255 (76.3%) psychiatric care providers responded. For questions related to the skills and attitudes of psychiatric professionals, 48.3%-58.4% of respondents perceived that efforts for supporting cancer screening and treatment were insufficient. For the questions related to collaborations between cancer and psychiatric care providers, 75.3% of respondents perceived that inpatient visits between psychiatric and cancer hospitals were insufficient. For the questions related to in-psychiatric-hospital medical systems, 50.2%-87.2% of respondents perceived that support for screening, diagnosis/treatment, and palliative care for psychiatric inpatients were insufficient/difficult. 41.9%-57.4% of respondents perceived that social services in the community were insufficient. CONCLUSIONS: This study clarified the level of insufficiency/difficulty perceived by psychiatric care providers regarding issues related to cancer care for people with mental illness. Psychiatric care providers are required to have knowledge and skills in cancer screening and treatment. To improve access to cancer prevention, treatment, and palliative care, it may be helpful to establish systems to promote coordination between cancer hospitals and psychiatric hospitals.

OBJECTIVE: This multicenter, retrospective, observational study investigated baseline characteristics and clinical outcomes in patients with hormone-sensitive prostate cancer who received primary androgen deprivation therapy, using Japan Study Group of Prostate Cancer registry data. METHODS: Among patients in the Japan Study Group of Prostate Cancer registry, those who initiated primary androgen deprivation therapy and were aged 20 years or older were enrolled in this study. The primary endpoint was time to disease progression, defined as time from primary androgen deprivation therapy initiation to either prostate-specific antigen or clinical progression. Secondary endpoints included prostate-specific antigen progression-free survival, prostate-specific antigen response (90% or greater reduction from baseline) and distribution of second-line treatment. RESULTS: Of the 2494 patients (goserelin, n = 564; leuprorelin, n = 1148; surgical castration, n = 161; degarelix, n = 621), those who received degarelix had higher prostate-specific antigen levels and Gleason scores and were at a more advanced clinical stage than those receiving goserelin or leuprorelin. The median time to disease progression (identical to the prostate-specific antigen progression-free survival result) was not reached for goserelin and leuprorelin, 52.7 months for surgical castration and 54.0 months for degarelix. Although baseline prostate-specific antigen values in the degarelix cohort were higher than those of the leuprorelin or goserelin cohorts, prostate-specific antigen responses were not different among the three cohorts. Regarding second-line treatment, the largest patient group received degarelix followed by leuprorelin (n = 195). CONCLUSIONS: This study clarified patient characteristics and long-term effectiveness of primary androgen deprivation therapy in real-world clinical practice. Japanese urologists appear to select appropriate primary androgen deprivation therapy based on patient background and tumour characteristics, with degarelix largely reserved for higher risk patients.
RESUMO
OBJECTIVES: To reduce cancer care disparities, this study aimed to clarify the difficulties in cancer care for people with mental disorders as perceived by cancer care providers. METHODS: Cancer care providers at 17 designated cancer hospitals in Japan were surveyed using mail questionnaires. Respondents were asked to rate 29 items related to difficulties or insufficiencies in cancer care for patients with mental disorders on a five-point Likert scale. We analyzed the proportion of respondents who answered "difficult/insufficient" in each item. We also calculated the proportions of responders stratified according to the presence of psychiatric support systems within their hospitals. RESULTS: A total of 388 (58.4%) cancer care providers responded. Among the issues related to "difficulties in diagnosing and treating cancer," support for decision-making, assessment of treatment adherence, and assessment of physical symptoms were perceived as most difficult (73.5%-81.5% of respondents). Among the issues related to 'difficulties or insufficiencies in collaboration among multidisciplinary health care providers,' the issue of advance consultation and sharing information with the patient's primary psychiatric care provider was perceived as most difficult (52.2%). Among the issues related to "insufficiencies of in-hospital and community medical systems," education to provide reasonable accommodation was perceived as most insufficient (47.4%). The perceived difficulties of over half of the issues varied significantly between hospitals depending on the level of psychiatric support systems. CONCLUSIONS: This study clarified the difficulties of cancer care in patients with mental disorders as perceived by cancer care providers. Some issues may be resolved by psychiatric liaison teams.

BACKGROUND: Patient-reported outcome (PRO) measures can provide valuable information in evaluating patients' health-related quality of life (HRQoL). Post hoc analysis of the AFTERCAB study was conducted to evaluate the HRQoL benefit of enzalutamide plus androgen deprivation therapy (ADT) compared to flutamide plus ADT for the treatment of patients with castration-resistant prostate cancer (CRPC) in Japan. METHODS: The open-label AFTERCAB study was conducted from November 2016 to March 2020 in Japanese men aged ≥ 20 years with asymptomatic or mildly symptomatic CRPC. Patients received enzalutamide plus ADT or flutamide plus ADT, respectively, as first-line alternative androgen therapy (AAT). HRQoL was analyzed through the Functional Assessment of Cancer Therapy-Prostate, EuroQoL 5-Dimension 5-Level instruments, Brief Pain Inventory-Short Form, and Brief Fatigue Inventory. The longitudinal changes in HRQoL, HRQoL deterioration based on minimally important difference (MID), and time to HRQoL deterioration were evaluated for first-line AAT. RESULTS: Overall, HRQoL between the enzalutamide and flutamide groups was similar during first-line treatment. No statistically significant HRQoL difference in change from baseline to week 61 (least square mean difference; p value) was observed. Furthermore, proportions of pain progression, symptom worsening, and HRQoL deterioration based on MID, were not significantly different between groups. CONCLUSIONS: The results were similar in all subscales of each PRO, demonstrating similar HRQoL deterioration based on MID criteria between the enzalutamide and flutamide groups.

BACKGROUND: Predicting the prognosis of patients with solitary fibrous tumor (SFT) is often difficult. The prognostic risk models developed by Demicco et al. are now the standard for evaluating the risk of SFT metastasis in the current World Health Organization classification of soft tissue and bone tumors. METHODS: In this study, we examined the prognostic usefulness of a modified version of the Demicco risk models that replaces the mitotic count with the Ki-67 labeling index. We compared the three-variable and four-variable Demicco risk models with our modified risk models using Kaplan-Meier curves based on data for 43 patients with SFT. RESULTS: We found a significant difference in metastasis-free survival when patients were classified into low-risk and intermediate/high-risk groups using the three-variable (P = 0.022) and four-variable (P = 0.046) Demicco models. There was also a significant difference in metastasis-free survival between the low-risk and intermediate/high-risk groups when the modified three-variable (P = 0.006) and four-variable (P = 0.022) models were used. CONCLUSION: Modified risk models that include the Ki-67 labeling index are effective for prediction of the prognosis in patients with SFT.

OBJECTIVES: There is no consensus about the follow-up schedule after 5-year cancer-free periods. In this study, we aimed to elucidate the risk factors for the recurrence in patients with non-muscle-invasive bladder cancer who remained cancer free for more than 5 years. METHODS: Data from six Japanese institutions were retrospectively reviewed. Among the patients with non-muscle-invasive bladder cancer who were treated with transurethral resection of bladder tumor between 1990 and 2013, those who had no recurrence for more than 5 years were included in this study. The Kaplan-Meier method and Cox hazards model were used to estimate recurrence-free survival and to determine the pathologic and clinical factors affecting late recurrence. RESULTS: In total, 434 patients were enrolled in this study. Of these patients, 55 patients (12.7%) experienced late recurrence. The median follow-up time was 8.9 years (interquartile range 6.9-11.3 years). Prior history of bladder cancer before the most recent transurethral resection was a significant predictor for late recurrence (hazard ratio 1.99 [95% confidence interval 1.13-3.47], P = 0.019), although other clinical factors including tumor grade, pathologic stage, tumor multiplicity, and current risk classification systems were not associated with late recurrence. CONCLUSIONS: Late recurrence after a long tumor-free period is not rare and it was not predicted by current risk classification systems. Only prior history of bladder cancer was a significant predictor for late recurrence in this study.

OBJECTIVES: To evaluate factors to predict overall survival of metastatic urothelial carcinoma patients treated with gemcitabine plus cisplatin chemotherapy or pembrolizumab therapy. METHODS: We retrospectively evaluated two metastatic urothelial carcinoma cohorts treated with (i) gemcitabine plus cisplatin or (ii) pembrolizumab. The gemcitabine plus cisplatin cohort was treated from December 2005 through December 2014 while the pembrolizumab cohort was treated from January 2018 through December 2020. Using multivariate analyses, we evaluated the risk factors for overall survival in each cohort and compared them. None of the gemcitabine plus cisplatin cohort patients were treated with pembrolizumab. All patients in the pembrolizumab cohort were treated with prior platinum-based chemotherapy. RESULTS: There were 184 patients in the gemcitabine plus cisplatin cohort and 91 in the pembrolizumab cohort. The mean follow-up periods were 714 and 284 days, respectively. In multivariate analysis, the risk factors for overall survival in the gemcitabine plus cisplatin cohort were liver metastasis, worse Eastern Cooperative Oncology Group performance status (1 or more), no primary site resection, and a high prognostic index (1 or more). In the pembrolizumab cohort, liver metastasis, bone metastasis, and worse Eastern Cooperative Oncology Group-performance status (1 or more), and high prognostic index (1 or more) were the risk factors for overall survival. In the pembrolizumab cohort, patients with a complete response or partial response during prior platinum-based chemotherapy had better overall survival with the following pembrolizumab treatment than those with stable or progressive disease (P = 0.004). CONCLUSIONS: Considering the similarity of these risk factors in two sequential treatments, it may be possible to predict the response to pembrolizumab according to the response to prior chemotherapy.

Penile cancer is a rare cancer for which no medical guidelines have been established before in Japan. These guidelines aim to standardize, as much as possible, the therapeutic modality for penile cancer, for which empirical evidence is limited on a global scale, thereby bolstering therapeutic outcomes for patients with penile cancer. The new guidelines conform to the Minds Guide for Developing Clinical Practice Guidelines (2017) as much as possible. However, virtually no randomized comparative studies and meta-analyses based on such randomized studies have been conducted. Therefore, only the findings available at present were listed after conducting an exhaustive literature review of items with extremely low evidence levels and for which bodies of evidence and grades of recommendation were not evaluated. Clinical questions were set for items with a relatively large number of studies, including retrospective studies. However, since it is virtually impracticable to summarize bodies of evidence by systematic reviews, recommendation grades and evidence levels were discussed and determined by the consensus panel of the Preparatory Committee. The following were outlined: epidemiological, pathological, diagnostic, therapeutic, follow-up, and quality of life-related findings. Additionally, seven clinical questions were established to determine recommendation grades and evidence levels. We hope that these guidelines will prove to be useful to medical professionals engaged in clinical practice related to penile cancer in Japan and anticipate that critical reviews of the guidelines will lead to further refinement of the next edition.

This study aimed to analyze the survival rate and to examine the risk of death from prostate cancer when accounting for competing risk of death, in men aged ≥80 y treated with primary androgen deprivation therapy (ADT). Data of patients with prostate cancer who had received ADT were extracted from a nationwide community-based database established by the Japan Study Group for Prostate Cancer. Prognostic variables, including progression-free survival, cancer-specific survival, overall survival, and death rates were compared between men stratified by prostate cancer risk. Overall, 4760 patients older than 80 y were included. The proportion of low-, intermediate-, high-, or very high-risk, regional, and metastatic prostate cancer among super-elderly men was 9.5%, 14.6%, 48.8%, 9.0%, 3.2%, and 24.9%, respectively. Survival rates decreased with increasing risk stratification. The cumulative 5-y death rate by prostate cancer for low-, intermediate-, high-, or very high-risk, regional, and metastatic prostate cancer, was 0.92% (95% confidence interval [CI]: 0.2%-3.6%), 1.6% (95% CI: 0.8%-3.4%), 5.75% (95% CI: 4.25%-7.75%), 15.6% (95% CI: 11.6%-23.3%), 20.7% (95% CI: 13.1%-31.7%), and 36.9% (95% CI: 32.8%-41.4%), respectively. Our findings support that there is no need for immediate ADT for low- and intermediate-risk groups. Conversely, in high- or very high-risk, regional, and metastatic prostate cancer, more efforts for curative therapy and intensive therapy are needed in selected patients.

OBJECTIVE: We examined the efficacy of a case management approach to improve participation in colorectal cancer screening among people with schizophrenia. METHODS: This was a randomized, parallel group trial. We recruited outpatients with schizophrenia aged 40 years or over from two psychiatric hospitals in Japan. Participants were randomly assigned (1:1) to treatment as usual or case management intervention plus treatment as usual using a web-based system. Attending clinicians and participants were unmasked to the allocation. Case management included education and patient navigation for colorectal cancer screening using a fecal occult blood test. Treatment as usual included direct mail government recommendations. The primary endpoint was participation in colorectal cancer screening assessed using municipal records. We also assessed the secondary endpoint of participation in other cancer screenings (lung, gastric, breast, and cervical). RESULTS: Between 3 June and 9 September 2019, 172 eligible participants were randomly assigned to the case management plus treatment as usual group (n = 86) or treatment as usual group (n = 86). One participant was ineligible and another withdrew consent; both were excluded from analysis. A significantly higher proportion of participants received colorectal cancer screening in the case management plus treatment as usual group than in the treatment as usual group (40 [47.1%] of 85 participants vs. 10 [11.8%] of 85 participants, p < 0.0001). The proportion of lung cancer screening also increased. No serious adverse events associated with the study intervention occurred. CONCLUSION: The case management intervention to encourage participation in colorectal cancer screening was effective for patients with schizophrenia.

BACKGROUND AND AIM: The current prevalence of hepatitis C virus infection and hepatitis C virus-associated mortality in Japan falls short of the World Health Organization goal of viral hepatitis elimination by 2030. We aimed to evaluate the trends in hepatitis C virus-associated mortality in Japan. METHODS: This nationwide observational study used the Japanese Vital Statistics from 1998 to 2017 and included all Japanese hepatitis C virus-associated deaths (84 936) of adults aged ≥ 40 years. We calculated the crude and age-standardized mortality rates per 100 000 persons by age and sex. Joinpoint regression analysis was used to identify significant changing points in trends and to estimate the annual percentage changes and the average annual percentage changes for the entire study period. RESULTS: The crude mortality rate per 100 000 persons (annual death number) increased from 5.5 (3548) in 1998 to 7.0 (4843) in 2005 and decreased to 4.0 (3095) in 2017. By 2017, the crude mortality rates per 100 000 persons among men and women had dropped to 3.6 and 4.3, respectively. The age-standardized mortality rate was higher in women than in men. The average annual percentage change was -3.8% (95% confidence interval: -5.0 to -2.5). The declining trend was more rapid in men (-4.5%, 95% confidence interval: -5.3 to -3.6) than in women (-2.7%, 95% confidence interval: -3.8 to -1.6). CONCLUSIONS: Trends in hepatitis C virus-associated mortality rates have declined in an accelerating manner in Japan, especially among men.

OBJECTIVES: The objectives of this study were to analyze the conditional survival and prognostic factors in androgen deprivation therapy for prostate cancer using the Japan Study Group of Prostate Cancer database. METHODS: Data on patients treated with primary androgen deprivation therapy between 2001 and 2003 from a nationwide database of the Japan Study Group of Prostate Cancer were used. The conditional 5-year progression-free rate, cancer-specific survival and overall survival, as well as the conditional mortality owing to prostate cancer and other causes were calculated as per subgroups. Prognostic factors for progression-free rate, cancer-specific survival and overall survival at each time after androgen deprivation therapy initiation were calculated using the Cox proportional hazards model. RESULTS: The conditional 5-year progression-free rate and cancer-specific survival, but not overall survival, gradually increased with time. The prognostic impact of stage IV characteristics (T4, N1 and M1) changed over time; however, the prognostic impact of the Gleason score remained unchanged. In the subgroup analysis, prostate-specific mortality risk reduced over time in patients with stage IV prostate cancer, whereas non-prostate cancer mortality increased over time in elderly patients. CONCLUSIONS: Information regarding conditional survival and mortality obtained in this study would provide a benchmark for physicians and cancer survivors.

OBJECTIVES: To examine the differences in prognosis of prostate cancer patients receiving primary androgen deprivation therapy by region and facility type using a Japan-wide database. METHODS: Data on patients treated with primary androgen deprivation therapy between 2001 and 2003 from a nationwide community-based database established by the Japan Study Group of Prostate Cancer were obtained. Clinicopathological characteristics and prognostic variables, including progression, cancer-specific survival and overall survival, were compared according to region and facility type where the patients were treated. RESULTS: Among 19 162 patients, 7102 (37.1%) and 12 060 (62.9%) men were in urban and rural areas, respectively, and 3556 (18.6%), 13 623 (71.1%) and 1983 (10.3%) patients were enrolled from academic centers, non-academic hospitals and urological clinics, respectively. The risks of progression, cancer-specific mortality and all-cause mortality were comparable between urban and rural areas in propensity-score matched analysis. Risks of progression, cancer-specific mortality and all-cause mortality in urological clinics were higher than those in academic centers in propensity-score matched analysis. CONCLUSIONS: Our findings suggest that Japan facility type, but not geographical regions, might affect the prognosis of prostate cancer patients receiving primary androgen deprivation therapy.
