RESUMEN
Established treatment options for rare cancers are limited by the small number of patients. The current comprehensive genomic profiling (CGP) testing might not fully exploit opportunities for precision oncology in patients with rare cancers. Therefore, we aimed to explore the factors associated with CGP testing utility in rare cancers and identify barriers to implementing precision oncology. Patients who underwent CGP testing at our institution between September 2019 and June 2021 were enrolled in this retrospective study. Based on their results, the patients received molecularly targeted drugs or immune checkpoint inhibitors. Univariate and multivariate analyses evaluated the association between patient characteristics and the proportion of patients receiving molecularly targeted drugs. Overall, 790 patients underwent CGP testing. Among them, 333 patients with rare cancers were identified, of whom 278 (83.5%) had actionable genomic alterations, 127 (38.1%) had druggable genomic alterations, and 25 (7.5%) received genomically matched therapy. The proportion of patients receiving molecularly targeted drugs was significantly higher among those with treatment options with evidence levels A-D (8.7%) than those without treatment options with evidence levels A-D (2.9%). A potential barrier to CGP testing utility in rare cancers is the limited number of molecularly targeted drugs with clinical evidence. We propose that CGP testing be performed in patients with rare cancers who have treatment options with evidence levels A-D to maximize CGP testing utility in real-world practice.

BACKGROUND: This study aimed to create a prognostic model to predict disease recurrence among patients with lymph node involvement but no prostate-specific antigen (PSA) persistence and to explore its clinical utility. METHODS: The study analyzed patients with lymph node involvement after pelvic lymph node dissection with radical prostatectomy in whom no PSA persistence was observed between 2006 and 2019 at 33 institutions. Prognostic factors for recurrence-free survival (RFS) were analyzed by the Cox proportional hazards model. RESULTS: Among 231 patients, 127 experienced disease recurrence. The factors prognostic for RFS were PSA level at diagnosis (≥ 20 vs. < 20 ng/mL: hazard ratio [HR], 1.66; 95% confidence interval [CI], 1.09-2.52; P = 0.017), International Society of Urological Pathology grade group at radical prostatectomy (RP) specimen (group ≥ 4 vs. ≤ 3: HR, 1.63; 95% CI 1.12-2.37; P = 0.010), pathologic T-stage (pT3b/4 vs. pT2/3a: HR, 1.70; 95% CI 1.20-2.42; P = 0.0031), and surgical margin status (positive vs. negative: HR, 1.60; 95% CI 1.13-2.28; P = 0.0086). The prognostic model using four parameters were associated with RFS and metastasis-free survival. CONCLUSION: The prognostic model in combination with postoperative PSA value and number of lymph nodes is clinically useful for discussing treatment choice with patients.

OBJECTIVE: To analyse the impact of histological discordance of subtypes (subtypes or divergent differentiation [DD]) in specimens from transurethral resection (TUR) and radical cystectomy (RC) on the outcome of the patients with bladder cancer receiving RC. PATIENTS AND METHODS: We analysed data for 2570 patients from a Japanese nationwide cohort with bladder cancer treated with RC between January 2013 and December 2019 at 36 institutions. The non-urinary tract recurrence-free survival (NUTR-FS) and overall survival (OS) stratified by TUR or RC specimen histology were determined. We also elucidated the predictive factors for OS in patients with subtype/DD bladder cancer. RESULTS: At median follow-up of 36.9 months, 835 (32.4%) patients had NUTR, and 691 (26.9%) died. No statistically significant disparities in OS or NUTR-FS were observed when TUR specimens were classified as pure-urothelial carcinoma (UC), subtypes, DD, or non-UC. Among 2449 patients diagnosed with pure-UC or subtype/DD in their TUR specimens, there was discordance between the pathological diagnosis in TUR and RC specimens. Histological subtypes in RC specimens had a significant prognostic impact. When we focused on 345 patients with subtype/DD in TUR specimens, a multivariate Cox regression analysis identified pre-RC neutrophil-lymphocyte ratio and pathological stage as independent prognostic factors for OS (P = 0.016 and P = 0.001, respectively). The presence of sarcomatoid subtype in TUR specimens and lymphovascular invasion in RC specimens had a marginal effect (P = 0.069 and P = 0.056, respectively). CONCLUSION: This study demonstrated that the presence of subtype/DD in RC specimens but not in TUR specimens indicated a poor prognosis. In patients with subtype/DD in TUR specimens, pre-RC neutrophil-lymphocyte ratio and pathological stage were independent prognostic factors for OS.

PURPOSE: The International Bladder Cancer Group designated the subgroup that is resistant to Bacillus Calmette-Guérin (BCG) but does not meet the criteria for BCG-unresponsive NMIBC as "BCG-exposed high-risk NMIBC" to guide optimal trial design. We aimed to investigate the treatment patterns and prognoses of patients with BCG-exposed NMIBC. METHODS: We conducted a retrospective chart review of 3283 patients who received intravesical BCG therapy for NMIBC at 14 participating institutions between January 2000 and December 2019. Patients meeting the criteria for BCG-exposed and BCG-unresponsive NMIBC, as defined by the Food and Drug Administration and International Bladder Cancer Group, were selected. To compare treatment patterns and outcomes, high-risk recurrence occurring more than 24 months after the last dose of BCG was defined as "BCG-treated NMIBC." In addition, we compared prognoses between BCG rechallenge and early cystectomy in patients with BCG-exposed NMIBC. RESULTS: Of 3283 patients, 108 (3.3%), 150 (4.6%), and 391 (11.9%) were classified as having BCG-exposed, unresponsive, and treated NMIBC, respectively. BCG-exposed NMIBC demonstrated intermediate survival curves for intravesical recurrence-free and progression-free survival, falling between those of BCG-unresponsive and treated NMIBC. Among patients with BCG-exposed NMIBC, 48 (44.4%) received BCG rechallenge, which was the most commonly performed treatment, and 19 (17.6%) underwent early cystectomy. No significant differences were observed between BCG rechallenge and early cystectomy in patients with BCG-exposed NMIBC. CONCLUSIONS: The newly proposed definition of BCG-exposed NMIBC may serve as a valuable disease subgroup for distinguishing significant gray areas, except in cases of BCG-unresponsive NMIBC.

BACKGROUND: Advanced (Stage IV) prostate and renal cancer have poor prognosis, and several therapies have been developed, but many are very costly. This study investigated drug regimens used in patients with untreated Stage IV prostate cancer and renal cell carcinoma and calculated the monthly cost of each. METHODS: We surveyed first-line drugs administered to patients with untreated Stage IV prostate cancer and renal cancer at Japan Clinical Oncology Group affiliated centers from April 2022 to March 2023. Drug costs were calculated according to drug prices in September 2023. Individual drug costs were calculated or converted to 28-day costs. RESULTS: A total of 700 patients with untreated Stage IV prostate cancer were surveyed. Androgen deprivation therapy + androgen receptor signaling inhibitor was the most common regimen (56%). The cost of androgen deprivation therapy + androgen receptor signaling inhibitor was 10.6-30.8-fold compared with conventional treatments. A total of 137 patients with Stage IV renal cancer were surveyed. Among them, 91% of patients received immune-oncology drug-based regimen. All patients received treatments with a monthly cost of ≥500 000 Japanese yen, and 80.4% of patients received treatments with a monthly cost of ≥1 million Japanese yen, of combination treatments. The cost of immune-oncology drug-based regimen was 1.2-3.1-fold that of TKI alone. CONCLUSION: To the best of our knowledge, this is the first report of a survey of first-line drug therapy in untreated Stage IV prostate cancer and renal cell carcinoma stratified by age and treatment costs. Our results show that most Japanese patients received state-of-the-art, effective treatments with high financial burden.

OBJECTIVE: Several guidelines recommended that second transurethral resection should be performed in patients with diagnosis of high-risk non-muscle-invasive bladder cancer. However, therapeutic benefits of second transurethral resection before bacillus Calmette-Guérin intravesical instillation were conflicting amongst previous studies. We investigated the prognostic impact of second transurethral resection before bacillus Calmette-Guérin instillation in high-risk non-muscle-invasive bladder cancer patients. METHODS: This retrospective study included 3104 non-muscle-invasive bladder cancer patients who received bacillus Calmette-Guérin instillations between 2000 and 2019 at 31 collaborative institutions. Univariate and multivariate Cox proportional hazards models were used to assess the risk factors of intravesical recurrence, disease progression, cancer-specific mortality and overall mortality. RESULTS: In the entire population, patients undergoing second transurethral resection (33%, 1026/3104) had a lower risk of intravesical recurrence on univariate analysis (hazard ratio 0.85, 95% confidence interval 0.73-0.98, P = 0.027), although it did not remain significant on multivariate analysis (hazard ratio 0.90, 95% confidence interval 0.76-1.07, P = 0.24). Subgroup analysis revealed that, in pT1 patients (n = 1487), second transurethral resection was significantly correlated with a lower risk of intravesical recurrence on multivariate analysis (hazard ratio 0.80, 95% confidence interval 0.64-1.00, P = 0.048), but lower risks of disease progression (hazard ratio 0.75, 95% confidence interval 0.56-1.00, P = 0.049), cancer-specific mortality (hazard ratio 0.54, 95% confidence interval 0.35-0.85, P = 0.007) and overall mortality (hazard ratio 0.73, 95% confidence interval 0.55-0.97, P = 0.027) on univariate analysis. CONCLUSIONS: Second transurethral resection confers accurate pathological staging and could be used to safely select good candidates for intravesical bacillus Calmette-Guérin instillation. We further confirm that second transurethral resection could confer an oncological benefit in pT1 bladder cancer patients treated by bacillus Calmette-Guérin instillation, and so strongly recommend second transurethral resection in this patient population.

BACKGROUND: The therapeutic role of pelvic lymph node dissection (PLND) during radical prostatectomy (RP) for prostate cancer is not established. In clinical practice, PLND is primarily performed in cases of high-risk prostate cancer. The detection of lymph node metastasis plays a crucial role in determining the need for subsequent treatments. This study aims to evaluate the prognosis of prostate cancer patients with lymph node involvement (LNI) by stratifying them based on postoperative prostate-specific antigen (PSA) levels to identify biomarkers that can guide postoperative treatment strategies. METHODS: Analysis was conducted on 383 patients, selected from 572 initially eligible, who underwent RP with LNI across 33 Japanese Urological Oncology Group institutions from 2006 to 2019. Patients were grouped according to postoperative PSA levels and salvage treatments received. Follow-up focused on castration resistance-free survival (CRFS), metastasis-free survival (MFS), and overall survival (OS). RESULTS: In the persistent PSA group (PSA ≥ 0.1 ng/mL), CRFS and MFS were significantly shorter compared to the non-persistent PSA group (PSA < 0.1 ng/mL), and there was a tendency for shorter OS. In the persistent PSA group, patients with postoperative PSA values above the median (PSA ≥ 0.52 ng/mL) showed shorter CRFS and MFS. Furthermore, in the PSA ≥ 0.52 group, androgen deprivation therapy (ADT) plus radiotherapy (RT) combination had prolonged CRFS and MFS compared with ADT alone. CONCLUSIONS: This study provides valuable insights into stratifying patients based on postoperative PSA levels to tailor postoperative treatment strategies, potentially improving the prognosis of prostate cancer patients with LNI.

BACKGROUND: Radical cystectomy in women generally includes the removal of the uterus, ovaries, and anterior vaginal wall, but the criteria for reproductive organ sparing are not clear. METHODS: A total of 2674 patients with bladder cancer were retrospectively reviewed, having undergone cystectomy at this nationwide multicenter from January 2013 to December 2019. We evaluated the incidence of malignancy in reproductive organs in a cohort of 417 women and analyzed the clinicopathological features of reproductive organ involvement. Recurrence-free survival and overall survival were reported using Kaplan-Meier survival curves. RESULTS: Median follow-up was 36.9 months. Of the 417 patients with urothelial carcinoma of the bladder, 325 underwent hysterectomy, and 92 had a spared uterus and anterior wall of the vagina. Twenty-nine (8.9%) patients exhibited reproductive organ involvement; this consisted of 22 (6.8%) uteri, 16 (4.9%) vaginas, and two (0.6%) ovaries. Incidental primary reproductive malignancies were found in only two (0.6%) patients. Recurrence-free survival and overall survival were significantly shorter in patients with reproductive organ involvement than in those without. Patients with reproductive organ involvement were more likely to have tumors with ≥ cT3 or sub-localization at the posterior/trigone/bladder neck. CONCLUSIONS: The risk of reproductive organ involvement cannot be ignored in women undergoing radical cystectomy for urothelial carcinoma of the bladder, therefore, the eligibility criteria for reproductive organ preservation should be considered carefully.
RESUMEN
OBJECTIVES: To determine the outcomes for elderly patients with de novo metastatic germ cell tumors and the influence of patient age on adherence to standard chemotherapy. METHODS: A total of 150 patients who were initially diagnosed with metastatic germ cell tumors and treated at our institution between 2007 and 2021 were included. Patients were classified according to three age groups: aged <40, 40-49, and ≥50 years. Clinicopathological features, adherence to standard first-line chemotherapy, overall survival, and disease-free survival were compared between these groups. We also analyzed the outcomes of patients who received low-intensity induction chemotherapy due to adverse events and/or comorbidities. RESULTS: There was no significant difference in any of the survival outcomes and in the rate of adherence to standard first-line chemotherapy between the three age groups, although elderly patients with intermediate/poor prognosis group tended to receive less-intense chemotherapies. The rate of febrile neutropenia as a chemotherapy-related adverse event was significantly higher in patients aged ≥50 years. No statistical significance in survival outcomes was detected between the group of patients who received relatively low-intensity induction chemotherapy and those who received adequately intensive planned chemotherapy. CONCLUSIONS: The adherence rate of standard fist-line chemotherapy of elderly patients is almost comparable to that of younger patients, although some adverse events should be carefully managed. Even elderly patients with metastatic germ cell tumors can aim for equivalently good survival outcome like younger populations, with effort to adhere to standard chemotherapy.

OBJECTIVES: This study aims to develop a prognostic model that estimates the post-operative risk of cancer-specific mortality in patients with bladder cancer who underwent radical cystectomy (RC). METHODS: We analyzed the data from patients with bladder cancer who had undergone radical cystectomy without receiving adjuvant chemotherapy across 36 institutions in the Japan Urological Oncology Group. The data were randomly split into training (N = 1348) and validation sets (N = 674) in a 2:1 ratio. Twenty-five variables were analyzed, and a multivariable Cox regression model predicting cancer-specific mortality was developed and validated. Prognostic scores were categorized into good and poor prognostic groups based on the upper tertile. The performance of the model was compared against the CheckMate 274 risk classification as a reference, which is used for determining the indication of adjuvant nivolumab therapy. RESULTS: The final model incorporated eight variables. In the validation set, it outperformed the CheckMate 274 risk classification with superior time-dependent area under the curves (5-year: 0.81 vs. 0.67) and was well-calibrated. Furthermore, our model reclassified 27.8% of patients categorized as high-risk by the CheckMate 274 risk classification into the good prognosis group. CONCLUSIONS: We developed and validated a prognostic model for patients with bladder cancer who underwent RC. This model will be beneficial in identifying patients with poor prognosis and those who are potential candidates for clinical trials of adjuvant therapy.
RESUMEN
OBJECTIVES: Immune checkpoint inhibitors and enfortumab vedotin have opened new avenues for sequential treatment strategies for locally advanced/metastatic urothelial carcinoma (la/mUC). In the pre-enfortumab vedotin era, many patients could not receive third-line treatment owing to rapid disease progression and poor general status. This study aimed to analyze real-world sequential treatment practices for la/mUC in Japan, with a focus on patients who do not receive third-line treatment. METHODS: We analyzed data for 1023 la/mUC patients diagnosed between January 2020 and December 2021 at 54 institutions from a Japanese nationwide cohort. RESULTS: At the median follow-up of 28.5 months, the median overall survival from first-line initiation for 905 patients who received systemic anticancer treatment was 19.1 months. Among them, 81% and 32% received second- and third-line treatment. Notably, 52% had their treatment terminated before the opportunity for third-line treatment. Multivariate logistic regression analysis revealed that low performance status (≥1), elevated neutrophil-to-lymphocyte ratio (≥3), and low body mass index (<21 kg/m2) at the start of first-line treatment were independent risk factors for not proceeding to third-line treatment (p = 0.0024, 0.0069, and 0.0058, respectively). In this cohort, 33% had one of these factors, 36% had two, and 15% had all three. CONCLUSIONS: This study highlights the high frequency of factors associated with poor tolerance to anticancer treatment in la/mUC patients. The findings suggest the need to establish optimal sequential treatment strategies, maximizing efficacy within time and tolerance constraints, while concurrently providing strong supportive care, considering immunological and nutritional aspects.

OBJECTIVES: To determine the effects of prophylactic urethrectomy (PU) on oncological and perioperative outcomes in patients with bladder cancer (BC) undergoing radical cystectomy (RC). METHODS: This retrospective study analyzed data on 1976 evaluable patients with BC who underwent RC. Patients were drawn from 36 institutions within the Japanese Urological Oncology Group. Oncological outcomes were compared using restricted mean survival times (RMSTs) based on inverse probability of treatment weighting (IPTW)-adjusted Kaplan-Meier curves for non-urinary tract recurrence-free survival (NUTRFS), cancer-specific survival (CSS), and overall survival (OS). Interaction terms within IPTW-adjusted Cox regression models were examined to assess the heterogeneity of treatment effect based on the risk of urethral recurrence (UR). The association between PU, estimated blood loss (EBL), and the incidence of severe postoperative surgical complications (SPSCs) (Clavien-Dindo grade 3 or higher) was analyzed. RESULTS: Of 1976 patients, 1448 (73.3%) received PU. IPTW adjustment was used to balance baseline characteristics between the treatment groups. Within the 107-month window of patient monitoring, PU showed no survival benefits (NUTRFS difference: 0.2 months [95% confidence interval: -6.8 to 7.3]; CSS, 1.2 [-4.9 to 7.3]; OS, 0 [-6.5 to 6.5]). No significant interactions were observed with factors associated with UR, and PU was associated with unfavorable perioperative outcomes (EBL, 1179 mL vs. 983 mL; SPSC, 14.6% vs. 7.0%). CONCLUSIONS: This study showed that (1) PU was not associated with survival in patients with BC undergoing RC, regardless of UR-associated factors, and (2) PU was associated with unfavorable perioperative outcomes.

OBJECTIVES: The American Joint Committee on Cancer (AJCC)/Union for International Cancer Control (UICC) 8th edition has proposed micrometastasis as a lymph node metastasis (LN+) of diameter ≤2 mm in prostate cancer. However, supporting evidence has not described. We evaluated LN+ patients' survival after radical prostatectomy (RP) based on the LN maximum tumor diameter (MTD). METHODS: Data from 561 LN+ patients after RP and pelvic LN dissection (PLND) treated between 2006 and 2019 at 33 institutions were retrospectively investigated. Patients were stratified by a LN+ MTD cutoff of 2 mm. Outcomes included castration resistance-free survival (CRFS), metastasis-free survival (MFS), cancer-specific survival (CSS), and overall survival (OS). RESULTS: In total, 282 patients were divided into two groups (LN+ MTD >2 mm [n = 206] and ≤2 mm [n = 76]). Patients of LN+ status >2 mm exhibited significantly decreased CRFS and MFS, and poorer CSS and OS. No patients developed CRPC in the LN+ status ≤2 mm group when the PLND number was ≥14. Multivariate analysis showed the number of LN removed, RP Gleason pattern 5, and MTD in LN+ significantly predicted CRFS. CONCLUSIONS: Patients of LN+ status ≤2 mm showed better prognoses after RP. In all the patients in the ≤2-mm group, the progression to CRPC could be prevented with appropriate interventions, particularly when PLND is performed accurately. Our findings support the utility of the pN substaging proposed by the AJCC/UICC 8th edition; this will facilitate precision medicine for patients with advanced prostate cancer.

OBJECTIVE: eribulin, an anticancer agent that inhibits microtubule growth, along with trabectedin and pazopanib, has been approved for the treatment of advanced soft tissue sarcoma (STS). However, there has been no consensus on the optimal second-line therapy among these three agents following treatment failure with doxorubicin. Recently, the effects of eribulin on the tumor microenvironment and immunity have been reported in breast cancer, and peripheral blood immune markers have also been reported to be a predictor of eribulin efficacy, though this remains unverified in STS. We aimed to evaluate the predictive value of various peripheral blood immune markers in STS patients treated with eribulin. METHODS: we retrospectively reviewed the medical records of STS patients treated with eribulin and examined whether peripheral blood immune markers at different time points could be prognostic factors for STS patients treated with eribulin. RESULTS: several peripheral blood immune markers were significantly associated with progression-free survival (PFS), specifically neutrophil-to-lymphocyte ratio (NLR) prestart (NLR before the initial administration of eribulin) (P = 0.019) and absolute lymphocyte count (ALC)8D (ALC on Day 8 of the first administration of eribulin) (P = 0.037). NLR prestart (P = 0.001) was significantly associated with overall survival. The combination of NLR prestart and ALC8D determined the PFS of STS patients treated with eribulin. CONCLUSIONS: the combined indicator of low NLR prestart and high ALC8D predicted the survival of patients treated with eribulin as well as the histology of L-sarcoma. Though further validation was needed, this finding would provide valuable prognostic factor that help treatment decision in the absence of consensus on the optimal second-line therapy following doxorubicin treatment in STS patients.

BACKGROUND: Cutaneous apocrine carcinoma (CAC) is a rare adnexal carcinoma. Limited data exists on the demographics and overall survival (OS) of patients with CAC; thus, there is no consensus on surgical management. This study aimed to examine demographic and survival data of patients with CAC to determine optimal surgical management. METHODS: A single-center retrospective cohort study was conducted at the National Cancer Center Hospital in Tokyo between 2005 and 2022. Patients with a histologically-confirmed CAC diagnosis were identified and data on patient demographics, OS, and lymph node (LN) status were gathered. RESULTS: Thirty-two patients were included (median age, 65.5 years; male-female ratio, 15:1). The most common involvement site was the axilla (87.5%). Of the nine patients in the clinical local stage, pathological LN metastases were found in five patients. Either pathological LN or distant metastases were present in 75% of the patients at initial diagnosis. The most common initial surgical treatments included wide local excision and complete LN dissection. Across cohorts, the median OS was 39 months. Patients with ≥ 4 LN metastases had reduced recurrence-free survival and OS compared to those with ≤ 3 LN metastases (p = 0.042, p = 0.041, respectively). The OS was not remarkably different between patients who did and did not receive postoperative radiation therapy. CONCLUSIONS: Since CAC has a high rate of LN metastasis-and the number of LN metastases is a significant prognostic factor-LN evaluation should be considered for patients with CAC as initial treatment. Nonetheless, ≥ 4 LN metastases can be a poor prognostic factor for CAC.

OBJECTIVES: To compare the therapeutic features and oncological outcomes of robot-assisted radical prostatectomy (RARP) with those of open radical prostatectomy (ORP) or laparoscopic radical prostatectomy (LRP) in lymph node (LN) positive prostate cancer patients in a retrospective observational multi-institutional study. PATIENTS AND METHODS: We evaluated the clinical results of 561 patients across 33 institutions who underwent RARP, LRP, or ORP and who were diagnosed with LN-positive prostate cancer during RP with pelvic LN dissection (PLND). We determined the following survival outcomes: metastasis-free survival, overall survival, cancer-specific survival, and biochemical recurrence-free survival. The Kaplan-Meier method, log-rank test, and Cox proportional hazards regression model were used to evaluate the effect of treatment on oncological outcomes. Statistical significance was set at P < 0.05. RESULTS: There was no significant difference for any of the survival outcomes between the three surgical groups. However, RARP achieved a greater LN yield compared to that of ORP or LRP. When the extent of PLND was limited to the obturator LNs, the number of removed LNs (RLNs) was comparable between the three surgical groups. However, higher numbers of RLNs were achieved with RARP compared to the number of RLNs with ORP (P < 0.001) when PLND was extended to the external and/or internal iliac LNs. CONCLUSION: RARP, LRP, and ORP provided equal surgical outcomes for pN1 prostate cancer, and the prognosis was relatively good for all procedures. Increased numbers of RLNs may not necessarily affect the oncological outcome.

Previous clinical trials indicate that 10%-25% of patients received genomically matched therapy after comprehensive genomic profiling (CGP) tests. However, the clinical utility of CGP tests has not been assessed in clinical practice. We assessed the clinical utility of CGP tests for advanced or metastatic solid tumor and determined the proportion of patients receiving genomically matched therapy among those with common and non-common cancers. From August 2019 to July 2020, a total of 418 patients had undergone CGP tests, and the results were discussed through the molecular tumor board at our site. The median age of patients was 57 (range: 3-86) years. Colorectal cancer was the most common, with 47 (11%) patients. Actionable genomic alterations (median 3, range: 1-17) were identified in 368 (88.0%) of 418 patients. Druggable genomic alterations were determined in 196 (46.9%) of 418 patients through the molecular tumor board. Genomically matched therapy was administered as the subsequent line of therapy in 51 (12.2%) patients, which is comparable to the proportion we previously reported in a clinical trial (13.4%) (p = 0.6919). The proportion of patients receiving genomically matched therapy was significantly higher among those with common cancers (16.2%) than non-common cancers (9.4%) (p = 0.0365). Genomically matched therapy after the CGP tests was administered to 12.2% of patients, which is similar to the proportion reported in the previous clinical trials. The clinical utility of CGP tests in patients with common cancers greatly exceeded that in patients with non-common cancers.

The treatment for lymph node involvement (LNI) after radical prostatectomy (RP) has not been established. This study aimed to reveal the outcomes of various management strategies among patients with LNI after RP. Retrospectively, 561 patients with LNI after pelvic lymph node dissection (PLND) with RP treated between 2006 and 2019 at 33 institutions participating in the Japanese Urological Oncology Group were investigated. Metastasis-free survival (MFS) was the primary outcome. Patients were stratified by prostate-specific antigen (PSA) persistence after RP. Cox regression models were used to analyze the relationships between clinicopathological characteristics and survival. Survival analyses were conducted using the Kaplan-Meier method and log-rank test with or without propensity score matching. Prognoses, including MFS and overall survival, were prominently inferior among patients with persistent PSA compared with those without persistent PSA. In multivariate analysis, androgen deprivation therapy (ADT) plus radiotherapy (RT) was associated with better MFS than ADT alone among patients with persistent PSA (hazard ratio = 0.37; 95% confidence interval = 0.15-0.93; p = 0.034). Similarly, MFS and overall survival were significantly better for ADT plus RT than for ADT alone among patients with persistent PSA after propensity score matching. This study indicated that PSA persistence in LNI prostate cancer increased the risk of poor prognoses, and intensive treatment featuring the addition of RT to ADT might improve survival.

BACKGROUND: Although radical prostatectomy is associated with good long-term oncological outcomes, approximately 30% of patients present biochemical recurrence, whereupon salvage treatments are required. Identification of novel molecular biomarkers to predict cancer behavior is clinically important. Here, we developed a novel microRNA (miRNA)-based prognostic model for patients who underwent radical prostatectomy. METHODS: We retrospectively investigated the clinical records of 295 patients who underwent radical prostatectomy between 2009 and 2017. We randomly assigned these cases into training or validation sets. The prognostic model was constructed using Fisher linear discriminant analysis in the training set, and we evaluated its performance in the validation set. RESULTS: Overall, 72 patients had biochemical recurrence. A prediction model was constructed using a combination of three miRNAs (miR-3147, miR-4513, and miR-4728-5p) and two pathological factors (pathological T stage and Gleason score). In the validation set, the predictive performance of the model was confirmed to be accurate (area under the receiver operating characteristic curve: 0.80; sensitivity: 0.78; specificity: 0.76). Additionally, Kaplan-Meier analysis revealed that the patients with a low prediction index had significantly longer recurrence-free survival than those with a high index (p < 0.001). CONCLUSIONS: Circulating miRNA profiles can provide information to predict recurrence after prostatectomy. Our model may be helpful for physicians to decide follow-up strategies for patients.

OBJECTIVES: To assess the impact of histological variants on survival and response to treatment with pembrolizumab in patients with chemo-resistant urothelial carcinoma (UC). PATIENTS AND METHODS: The medical records of 755 patients with advanced UC who received pembrolizumab were reviewed retrospectively. Patients were classified into pure UC (PUC) and each variant. Best overall response (BOR) and overall survival (OS) were compared between the groups using a propensity score matching (PSM). RESULTS: Overall, 147 (19.5%) patients harboured any histological variant UC (VUC). After PSM, there were no significant differences in the objective response rate (ORR, 24.5% vs 17.3%, P = 0.098) or disease control rate (DCR, 36.7% vs 30.2%, P = 0.195) when comparing patients with any VUC and PUC. Furthermore, any VUC, as compared with PUC, was associated with a similar risk of death (hazard ratio [HR] 0.90, 95% confidence interval [CI] 0.68-1.20; P = 0.482). Squamous VUC, which was the most frequent variant in the cohort, had a comparable ORR, DCR and OS as compared with PUC or non-squamous VUC. The patients with sarcomatoid VUC (n = 19) had significantly better ORR (36.8%, P = 0.031), DCR (52.6%, P = 0.032), and OS (HR 0.37, 95% CI 0.15-0.90; P = 0.023) compared to patients with PUC. CONCLUSIONS: The presence of variant histology did not seem to affect BOR or OS after pembrolizumab administration in patients with chemo-resistant UC. The patients with sarcomatoid VUC achieved favourable responses and survival rates compared to PUC.
