RESUMEN
INTRODUCTION: Prostate leiomyosarcoma is a rare, aggressive neoplasm. CASE PRESENTATION: A 52-year-old man presented with worsening frequent micturition and painful urination. Rectal examination revealed a significantly enlarged prostate. Magnetic resonance imaging showed a large prostate tumor with urinary bladder and bilateral seminal vesicle invasion. A prostate biopsy revealed diffuse proliferation of pleomorphic atypical cells. Immunohistochemistry confirmed the diagnosis of prostrate leiomyosarcoma. The patient received three cycles of the mesna, doxorubicin, ifosfamide, and dacarbazine regime (mesna 6000 mg/m2, doxorubicin 60 mg/m2, ifosfamide 7500 mg/m2, and dacarbazine 900 mg/m2) at 4-week intervals. The tumor shrank by 28% and exhibited necrotic changes. He underwent total pelvic exenteration with en bloc resection of the prostate, bladder, rectum, and anus. Pathological surgical margin was negative. The patient is alive with no disease at 5 years postoperatively. CONCLUSION: Neoadjuvant chemotherapy and surgical resection are essential to achieve a long-term survival of patients with localized prostate leiomyosarcoma.
RESUMEN
BACKGROUND: Anemia has been a known prognostic factor in metastatic hormone-sensitive prostate cancer (mHSPC). We therefore examined the effect of anemia on the efficacy of upfront abiraterone acetate (ABI) in patients with mHSPC. METHODS: We retrospectively evaluated 66 mHSPC patients with high tumor burden who received upfront ABI between 2018 and 2020 (upfront ABI group). We divided these patients into two groups: the anemia-ABI group (hemoglobin < 13.0 g/dL, n = 20) and the non-anemia-ABI group (n = 46). The primary objective was to examine the impact of anemia on the progression-free survival (PFS; clinical progression or PC death before development of castration resistant PC) of patients in the upfront ABI group. Secondary objectives included an evaluation of the prognostic significance of upfront ABI and a comparison with a historical cohort (131 mHSPC patients with high tumor burden who received androgen deprivation therapy (ADT/complete androgen blockade [CAB] group) between 2014 and 2019). RESULTS: We found that the anemia-ABI group had a significantly shorter PFS than the non-anemia-ABI group. A multivariate Cox regression analysis showed that anemia was an independent prognostic factor of PFS in the upfront ABI group (hazard ratio, 4.66; P = 0.014). Patients in the non-anemia-ABI group were determined to have a significantly longer PFS than those in the non-anemia-ADT/CAB group (n = 68) (P < 0.001). However, no significant difference was observed in the PFS between patients in the anemia-ABI and the anemia-ADT/CAB groups (n = 63). Multivariate analyses showed that upfront ABI could significantly prolong the PFS of patients without anemia (hazard ratio, 0.17; P < 0.001), whereas ABI did not prolong the PFS of patients with anemia. CONCLUSION: Pretreatment anemia was a prognostic factor among mHSPC patients who received upfront ABI. Although the upfront ABI significantly improved the PFS of mHSPC patients without anemia, its efficacy in patients with anemia might be limited.

BACKGROUND: The clinical benefit of the combined androgen blockade (CAB) therapy over luteinizing hormone-releasing hormone analog (LH-RHa) monotherapy for hormone naïve metastatic prostate cancer (mHNPC) is unclear. Therefore, we retrospectively compare the effectiveness of CAB with the LH-RHa monotherapy on the prognosis of Japanese patients with mHNPC. METHODS: We retrospectively evaluated the prognosis of 517 patients diagnosed with mHNPC between August 2001 and May 2017. The patients' data were obtained from the Michinoku Urological Cancer Research Group database and Hirosaki University-related hospitals. Patients were divided into the CAB and LH-RHa monotherapy groups based on primary androgen deprivation therapy (ADT). Overall survival (OS), cancer-specific survival (CSS), and castrate-resistant prostate cancer-free survival (CRPC-FS) were compared between the two groups using the Kaplan-Meier curve analysis. Inverse probability of treatment weighting (IPTW)-adjusted Cox hazard proportional analyses was performed to investigate the effect of primary ADT on oncological outcomes. RESULTS: The median age was 73 years old. The numbers of patients in the CAB and LH-RHa monotherapy groups were 447 and 70, respectively. The Kaplan-Meier curve analysis showed no significant differences in either 5-year OS (56.7% vs. 52.5%, P=0.277), CSS (61.1% vs. 56.4%, P=0.400), and CRPC-FS (33.1% vs. 31.1%, P=0.529) between the groups. IPTW-adjusted multivariate Cox hazard proportional analyses showed no significant differences in OS, CSS, and CRPC-FS between the two groups. CONCLUSIONS: No significant differences in oncological outcomes were observed between the CAB and LH-RHa monotherapy groups in patients with mHNPC.
RESUMEN
BACKGROUND: This study compared real-world outcomes of metastatic renal-cell carcinoma (mRCC) patients treated with tyrosine kinase inhibitors or nivolumab plus ipilimumab. METHODS: Using the International mRCC Database Consortium (IMDC), we retrospectively evaluated intermediate- and poor-risk mRCC patients who were treated with nivolumab plus ipilimumab (Nivo-Ipi), tyrosine kinase inhibitors (TKIs) as the first-line therapy between August 2015 and January 2020. We compared oncological outcomes between the Nivo-Ipi group and TKIs group using multivariate logistic regression analysis with the inverse probability of treatment weighting (IPTW) method. RESULTS: In this study 278 patients were included. There were 52 and 226 patients in the Nivo-Ipi and TKIs groups (sunitinib 97, axitinib 118, sorafenib 9, pazopanib 2), respectively. The median age in the Nivo-Ipi and TKIs groups were 69 and 67 years, respectively. There was no significant difference in age, performance status, history of nephrectomy, and the IMDC risk group distribution between the groups. The objective response rate was significantly higher in the Nivo-Ipi group (38%) than in the TKIs group (23%, P = 0.018). The IPTW-adjusted Cox regression analysis showed that a significantly longer progression-free survival (hazard ratio 0.60, P = 0.039) and overall survival (hazard ratio 0.51, P = 0.037) rates in the Nivo-Ipi group than those in the TKIs group. CONCLUSIONS: The oncological outcomes of patients receiving the first-line therapy of nivolumab plus ipilimumab in real-world practice were significantly improved in comparison with first-line TKIs therapy.

OBJECTIVES: To investigate the association between Ki67 index and programmed death-ligand 1 (PD-L1) expression in muscle-invasive bladder cancer (MIBC) patients after RC. MATERIALS AND METHODS: We retrospectively evaluated 262 MIBC patients treated with RC between April 2004 and April 2020. The impact of Ki67 index and PD-L1 expression on prognosis was evaluated by univariate Cox regression analysis. In addition, a pathomolecular risk score, including Ki67 and PD-L1, was developed to predict prognosis and pathological factors. We also evaluated the link between the Ki67 index and PD-L1 under the IL-6 stimulation in the bladder cancer cell lines of T24 and 5637 cells. RESULTS: The median age and follow-up period was 69 years and 52 months, respectively. Ki67 index and PD-L1 expression were significantly associated with tumor recurrence. Univariate Cox regression analysis showed that pT3-4, mixed histology, lymphovascular invasion positive (LVI+), pN+, Ki67-high (>17%), and PD-L1+ were significantly associated with recurrence-free survival (RFS). The pathomolecular risk score was developed using resection margin+ (1 point), mixed histology (1 point), LVI+ (1 point), pN+ (1 point), and Ki67-high (1 point). RFS and overall survival were significantly shorter in patients with higher pathomolecular risk scores (>1) than in those with lower risk scores (≤1). Cell proliferation was significantly increased in the T24 and 5637 cells under the IL-6 stimulation, while PD-L1 expression was not. CONCLUSIONS: A significant effect of Ki67-high and PD-L1 expression on poor prognosis was observed in patients with MIBC. Further studies are necessary to elucidate the precise mechanisms of cell proliferation and PD-L1 expression in patients with MIBC.

OBJECTIVES: To investigate the efficacy and safety of first-line nivolumab plus ipilimumab for patients treated with metastatic renal cell carcinoma. METHODS: We retrospectively evaluated 52 metastatic renal cell carcinoma patients who were treated with nivolumab plus ipilimumab between August 2015 and January 2020. Data on patient characteristics, treatment parameters and adverse events were obtained. Oncological outcomes were assessed according to the International Metastatic Renal Cell Carcinoma Database Consortium prognostic model. Furthermore, differences in treatment parameters between patients with objective response (responders) and non-responders were compared. RESULTS: The median age and follow-up periods were 69 years and 8.2 months, respectively. The 1-year progression-free survival and overall survival rates were 55% and 75%, respectively. The objective response rate was 39%, and it was significantly different between the International Metastatic Renal Cell Carcinoma Database Consortium intermediate- and poor-risk groups (52% vs 24%). We observed 36 (69%) any immune-related adverse events, and 19 (37%) severe immune-related adverse events (grades III-V). The International Metastatic Renal Cell Carcinoma Database Consortium poor-risk group and higher value of initial C-reactive protein (≥1.0 mg/dL) were significantly associated with non-responders. Patients with two factors (the International Metastatic Renal Cell Carcinoma Database Consortium poor-risk group plus C-reactive protein ≥1.0 mg/dL) had a significantly poor overall survival than those with none or a single factor. CONCLUSIONS: In our experience, treatment response to nivolumab plus ipilimumab is comparable with that of the CheckMate 214 clinical trial, but the incidence of treatment-related adverse events is lower. The International Metastatic Renal Cell Carcinoma Database Consortium poor-risk group and initial C-reactive protein value might have a prognostic value for poor survival.

OBJECTIVES: To evaluate the association of tumor burden with the prognosis in real-world patients with metastatic castration-sensitive prostate cancer and to investigate the eligibility for upfront intensification therapy. METHODS: We retrospectively evaluated 679 patients with metastatic castration-sensitive prostate cancer who were initially treated with conventional androgen deprivation therapy between August 2001 and November 2018. The primary purpose was to investigate the eligibility for upfront intensification therapy based on the progression of metastatic castration-resistant prostate cancer. The secondary purpose included the comparison of the metastatic castration-resistant prostate cancer progression rate, metastatic castration-resistant prostate cancer-free survival and overall survival after castration-resistance in CHAARTED low- or high-volume disease patients. RESULTS: The number of patients with metastatic castration-resistant prostate cancer progression was 119 (52%) and 319 (71%) in the low- and high-volume disease groups, respectively. The metastatic castration-resistant prostate cancer progression rate (P < 0.001) and castration-resistant prostate cancer-free survival (P < 0.001) were significantly different between the low- and high-volume disease groups, but no difference was found for overall survival after castration resistance (P = 0.363). Multivariate Cox regression analysis showed no significant association between tumor burden and overall survival after castration resistance (P = 0.522; hazard ratio 1.14). CONCLUSIONS: The progression rate in metastatic castration-resistant prostate cancer patients with the low-volume disease under conventional androgen deprivation therapy is approximately 50%. Upfront intensification therapy might be beneficial for approximately half of patients with low-volume disease. A novel maker to predict the castration-resistant status is required to select optimal patients for upfront intensification therapy.

OBJECTIVES: To investigate the effect of frailty on the type of urinary diversion after radical cystectomy in patients with muscle-invasive bladder cancer. METHODS: Between January 2014 and January 2020, we prospectively evaluated frailty in 88 patients with localized muscle-invasive bladder cancer, who had received radical cystectomy and urinary diversion. The selection of the type of urinary diversion was determined by the operating surgeon based on performance status, comorbidities, tumor status and the patient's preference. The frailty evaluation included the Fried phenotype criteria, the modified frailty index and the frailty discriminant score. We investigated the association between frailty and type of urinary diversion, the effect of frailty on postoperative complications and the effect of frailty on overall survival. RESULTS: The median age of the selected participants was 68 years. The number of patients with an orthotopic neobladder and any postoperative complications was 54 (61%) and 46 (52%), respectively. Of the frailty assessment tools that were used, Fried phenotype criteria and frailty discriminant score were significantly associated with the selection of non-orthotopic neobladder urinary diversion. Occurrences of postoperative complications in participants were significantly associated with modified frailty index, but not with Fried phenotype criteria and frailty discriminant score. Multivariate Cox regression analysis showed that a higher frailty discriminant score was significantly associated with poor overall survival, whereas higher Fried phenotype criteria and modified frailty index were not. CONCLUSION: Frailty is significantly associated with the type of urinary diversion, and it should be considered for the selection of urinary diversion in muscle-invasive bladder cancer patients undergoing radical cystectomy.

PURPOSE: Clinical outcomes of patients with newly diagnosed metastatic hormone-naïve prostate cancer (mHNPC) and initially treated with androgen deprivation therapy (ADT) were evaluated. METHODS: The medical records of 605 consecutive mHNPC patients with initial ADT or combined androgen blockade (CAB) at nine study centers between 2008 and 2016 were retrospectively reviewed. Castration-resistant prostate cancer (CRPC)-free and overall survival (OS) were estimated by the Kaplan-Meier method. The association of pretreatment risk factors with CRPC-free survival and OS was evaluated by Cox proportional hazard models and differences in survival were classified by the number of risk factors. RESULTS: Median follow-up was 2.95 years, median CRPC-free survival was 21.9 months and median OS was 5.37 years. Multivariable analysis found that four risk factors, a Gleason score ≥ 9, lymph node metastasis, an extent of disease score ≥ 2, and serum LDH of > 220 IU were independently associated with both CRPC-free survival and OS. Median CRPC-free survival of low-risk patients with no or one factor was 86.5 months, 17.9 months in intermediate-risk patients with two or three factors, and 11.0 months in high-risk patients with four factors. Median OS was 4.72 years in intermediate- and 2.44 years in high-risk patients. It was not reached in low-risk patients. CONCLUSION: In this series, CRPC-free and OS of a subset of mHNPC patients in Japan who were treated with ADT or CAB had better CRPC-free and overall survivals in Japan. Risk-adapted treatment based on the presence of novel prognostic factors may be beneficial for selected mHNPC patients.

INTRODUCTION: We aimed to evaluate the treatment sequence for patients with metastatic castration-resistant prostate cancer (mCRPC) in real-world practice and compare overall survival in each sequential therapy. PATIENTS AND METHODS: We retrospectively evaluated 146 patients with mCRPC who were initially treated with androgen deprivation therapy as metastatic hormone-naive prostate cancer in 14 hospitals between January 2010 and March 2019. The agents for the sequential therapy included new androgen receptor-targeted agents (ART: abiraterone acetate or enzalutamide), docetaxel, and/or cabazitaxel. We evaluated the treatment sequence for mCRPC and the effect of sequence patterns on overall survival. RESULTS: The median age was 71 years. A total of 35 patients received ART-ART, 33 received ART-docetaxel, 68 received docetaxel-ART, and 10 received docetaxel-cabazitaxel sequences. The most prescribed treatment sequence was docetaxel-ART (47%), followed by ART-ART (24%). Overall survival calculated from the initial diagnosis reached 83, 57, 79, and 37 months in the ART-ART, ART-docetaxel, docetaxel-ART, and docetaxel-cabazitaxel, respectively. Multivariate Cox regression analyses showed no significant difference in overall survival between the first-line ART (n = 68) and first-line docetaxel (n = 78) therapies (hazard ratio [HR], 0.84; P = .530), between the ART-ART (n = 35) and docetaxel-mixed (n = 111) sequences (HR, 0.82; P = .650), and between the first-line abiraterone (n = 32) and first-line enzalutamide (n = 36) sequences (HR, 1.58; P = .384). CONCLUSION: The most prescribed treatment sequence was docetaxel followed by ART. No significant difference was observed in overall survival among the treatment sequences in real-world practice.

INTRODUCTION: This study aimed to investigate the effect of low prostate-specific antigen (PSA) on prognosis, as the association of initial PSA level with prognosis in patients with metastatic castration-naive prostate cancer (mCNPC) remains unclear. PATIENTS AND METHODS: We evaluated 575 patients with mCNPC from 10 hospitals. Patients were stratified into 2 groups according to their initial PSA: PSA < 100 and PSA ≥ 100 groups. We compared castration-resistant prostate cancer (CRPC)-free survival, overall survival (OS), and OS from the CRPC diagnosis between the groups. Multivariate Cox regression analysis was performed to evaluate the effect of initial PSA level on prognosis. RESULTS: Of the 575 patients, 196 (34%) patients belonged to the PSA < 100 group. No significant difference was found in patients' backgrounds except for PSA, the extent of disease, and high tumor burden between the groups. CRPC-free survival was significantly shorter in the PSA ≥ 100 group than in the PSA < 100 group. However, the OS after CRPC diagnosis was significantly shorter in the PSA < 100 group than that of the PSA ≥ 100 group. Multivariate analyses showed that PSA < 100 ng/mL was an independent factor for OS after CRPC, whereas no significant association was observed in the CRPC-free survival and OS. CONCLUSIONS: A significant effect of initial PSA < 100 ng/mL on OS after CRPC was observed. PSA < 100 ng/mL might be a poor prognostic factor in patients with mCNPC after CRPC.

BACKGROUND: The purpose of this study was to identify predictive factors associated with conditional net survival in patients with metastatic hormone-naive prostate cancer (mHNPC) initially treated with androgen deprivation therapy (ADT). METHODS: At nine hospitals in Tohoku, Japan, the medical records of 605 consecutive patients with mHNPC who initially received ADT were retrospectively reviewed. The Pohar Perme estimator was used to calculate conditional net cancer-specific survival (CSS) and overall survival (OS) for up to 5 years subsequent to the diagnosis. Using multiple imputation, proportional hazard ratios for conditional CSS and OS were calculated with adjusted Cox regression models. RESULTS: During a median follow up of 2.95 years, 208 patients died, of which 169 died due to progressive prostate cancer. At baseline, the 5-year CSS and OS rates were 65.5% and 58.2%, respectively. Conditional 5-year net CSS and OS survival gradually increased for all the patients. In patients given a 5-year survivorship, the conditional 5-year net CSS and OS rates improved to 0.906 and 0.811, respectively. Only the extent of disease score (EOD) ≥2 remained a prognostic factor for CSS and OS up to 5 years; as survival time increased, other variables were no longer independent prognostic factors. CONCLUSIONS: The conditional 5-year net CSS and OS in patients with mHNPC gradually increased; thus, the risk of mortality decreased with increasing survival. The patient's risk profile changed over time. EOD remained an independent prognostic factor for CSS and OS after 5-year follow-up. Conditional net survival can play a role in clinical decision-making, providing intriguing information for cancer survivors.

We prospectively validate the efficacy of the frailty discriminant score (FDS) in individuals with urological cancers, as there has been growing importance in evaluating frailty in clinical practice. A prospective, multicenter study was conducted from February 2017 to April 2019. We enrolled 258 patients with urological cancers and 301 community-dwelling participants who were assessed for frailty. Frailty was assessed using FDS that includes ten items, such as physical, mental, and blood biochemical tests. The primary outcome was the non-inferiority (margin 5%) of FDS in discriminating patients with urological cancers from controls (Ctrl). The sensitivity, specificity, and area under the receiver operating characteristic (AUROC) curve for each predictive test were calculated. The secondary endpoints included the prediction of overall survival between patients with urological cancer who have high and low FDS. FDS was significantly higher in patients with urological cancers than that in the Ctrl. The AUROC curves for individuals with non-prostate cancers (such as bladder cancer, upper tract urothelial carcinoma, and renal cell carcinoma; 0.942) and those with prostate cancer (0.943) were within the non-inferior margin. The overall survival values were significantly lower in patients with higher FDS score than in those with lower FDS score. The study met its primary and secondary endpoints. The FDS is a reliable and valid tool for assessing frailty and prognosis in patients with urological cancers.

We evaluated the impact of early changes in serum biomarker levels on the survival of patients with metastatic hormone-sensitive prostate cancer (mHSPC) who were initially treated with androgen deprivation therapy (ADT). We retrospectively investigated 330 patients with mHSPC whose serum maker levels were at baseline and at 2-4 months. An optimal Cox regression model was established with the highest optimism-corrected concordance index based on 10-fold cross-validation. The median cancer-specific survival (CSS) and overall survival (OS) were 7.08 and 6.47 years (median follow-up, 2.53 years), respectively. In the final optimal Cox model with serum biomarker levels treated as time-varying covariates, prostate-specific antigen (PSA), hemoglobin (Hb), and alkaline phosphatase (ALP) significantly increased the risk of poor survival in the context of both CSS and OS. Kaplan-Meier curves stratified by the three risk factors of high PSA, low Hb and high ALP desmondtated that median OS were not reached with none of these factors, 6.47 years with one or two factors, and 1.76 years with all three factors.Early changes in serum biomarker levels after ADT may be good prognostic markers for the survival of patients with mHSPC.

BACKGROUND: The objective of the study was to validate the characteristics of the International Metastatic Renal-Cell Carcinoma Database Consortium (IMDC) prognostic model in patients treated with first-line axitinib in clinical practice. PATIENTS AND METHODS: We retrospectively evaluated 143 patients with metastatic renal-cell carcinoma who were treated with axitinib as the first-line therapy between October 2008 and February 2019. Overall survival (OS) was evaluated according to the IMDC prognostic model. We investigated the intragroup heterogeneity in the intermediate-risk group and divided these patients according to abnormal C-reactive protein (CRP) levels. An inverse probability of treatment-weighted (IPTW)-adjusted Cox regression analysis was performed to evaluate the effects of the CRP-risk model of OS in the patients in the IMDC intermediate-risk group. RESULTS: A significant difference in OS was observed in patients in the IMDC intermediate- and poor-risk group, although no significant difference was observed between the IMDC favorable- and intermediate-risk group. Significantly shorter prognosis was observed in patients in the IMDC intermediate-risk group who had 2 risk factors and CRP ≥0.3 mg/dL (inter-high group) than in those with 1 risk factor or 2 risk factors with CRP <0.3 mg/dL (inter-low group). IPTW-adjusted Cox regression analysis revealed significant differences in the OS between the inter-low and inter-high groups. CONCLUSION: The IMDC prognostic model was active in patients who received first-line axitinib treatment. The combination of CRP value with the number of positive risk factors in the IMDC model might predict prognosis in patients with IMDC intermediate-risk treated with first-line axitinib.

OBJECTIVES: To evaluate the effect of pretreatment C-reactive protein/albumin ratio and modified Glasgow prognostic score on the prognosis in patients with metastatic renal cell carcinoma. METHODS: A retrospective study was carried out in 176 patients with metastatic renal cell carcinoma who received first-line tyrosine kinase inhibitors. The effect of adding inflammatory prognostic scores to the International Metastatic Renal Cell Carcinoma Database Consortium model (International Metastatic Renal Cell Carcinoma Database Consortium-C-reactive protein/albumin ratio and International Metastatic Renal Cell Carcinoma Database Consortium-Glasgow prognostic score models) on overall survival was evaluated using receiver operating characteristic curves. The prognostic value of inflammatory prognostic scores (C-reactive protein/albumin ratio-modified Glasgow prognostic score) was tested using the Kaplan-Meier method and Cox proportional regression models. RESULTS: Patients were stratified into two groups using the cut-off value of 0.05: C-reactive protein/albumin ratio-low (<0.05) and C-reactive protein/albumin ratio-high (≥0.05). The area under the curve was significantly higher in the International Metastatic Renal Cell Carcinoma Database Consortium-C-reactive protein/albumin ratio model (0.720) than that of the International Metastatic Renal Cell Carcinoma Database Consortium model (0.689) and the International Metastatic Renal Cell Carcinoma Database Consortium-modified Glasgow prognostic score model (0.703). Significant differences were observed in overall survival stratified by the number of risk factors in the International Metastatic Renal Cell Carcinoma Database Consortium-C-reactive protein/albumin ratio risk model between one or two and three or four factors (P < 0.001), and three or four and five or more factors (P = 0.001). For the patients in the International Metastatic Renal Cell Carcinoma Database Consortium intermediate-risk group, overall survival was significantly different between the C-reactive protein/albumin ratio-low and -high groups (P = 0.001), whereas it was not significantly different between the patients with one and two International Metastatic Renal Cell Carcinoma Database Consortium risk factors (P = 0.106). CONCLUSION: The C-reactive protein/albumin ratio is a simple and independent predictor of overall survival in patients with metastatic renal cell carcinoma. The predictive activity was significantly improved in the International Metastatic Renal Cell Carcinoma Database Consortium-C-reactive protein/albumin ratio model compared with the International Metastatic Renal Cell Carcinoma Database Consortium/International Metastatic Renal Cell Carcinoma Database Consortium-modified Glasgow prognostic score models.

PURPOSE: To investigate the impact of the risk group disagreement between the Memorial Sloan Kettering Cancer Center (MSKCC) and the International Metastatic Renal Cell Carcinoma Database Consortium (IMDC) models on prognosis. PATIENTS AND METHODS: We retrospectively evaluated 176 patients with metastatic renal-cell carcinoma who were treated with tyrosine kinase inhibitors as first-line therapy in 5 hospitals between October 2008 and August 2018. The risk group classification differences between the MSKCC and the IMDC models were evaluated using criteria of agreement (identical risk group in both the MSKCC and IMDC models) and disagreement (not identical risk group in both the MSKCC and IMDC models). The agreement of risk stratification between the models was evaluated using the Cohen κ coefficient. Oncologic outcomes were compared between the agreement and disagreement groups. RESULTS: The number of patients with agreement, upgrade, and downgrade was 135 (77%), 39 (22%), and 2 (1.1%), respectively. Of 41 patients with disagreement, reclassification from the MSKCC-intermediate to the IMDC-poor risk group was most frequent (n = 34, 19%). The Cohen κ coefficient for agreement was substantial, with κ = 0.613 (P < .001). Significantly poorer prognosis was observed in patients with disagreement than in those with agreement. Neutrophil count, hemoglobin, serum calcium concentration, and C-reactive protein were significantly different between the groups. CONCLUSION: Disagreement between the MSKCC and IMDC models may have a negative impact on prognosis in patients with metastatic renal-cell carcinoma. The inclusion of systematic inflammation markers in a risk model may be essential for prognosis prediction.

PURPOSE: We determine whether the nadir prostate-specific antigen level (PSA nadir) and time to nadir (TTN) during initial androgen deprivation therapy (ADT) are prognostic factors in metastatic castration-resistant prostate cancer (mCRPC) patients. METHODS: We reviewed the Michinoku Japan Urological Cancer Study Group database, including 321 mCRPC patients. Optimal cutoff values for PSA nadir and TTN on survival were calculated with the receiver operating characteristic (ROC) curve. Patients were stratified into unfavorable (higher PSA nadir and/or shorter TTN) and favorable (lower PSA nadir and longer TTN) groups. The inversed probability of treatment weighing (IPTW)-adjusted Cox proportional hazard model was performed to evaluate the impact of the unfavorable group on overall survival (OS) after CRPC diagnosis. RESULTS: Median age and follow-up period were 71 years and 35 months, respectively. ROC curve analysis demonstrated cutoffs of PSA nadir > 0.64 ng/mL and TTN < 7 months. The unfavorable group included 248 patients who had significantly shorter OS after mCRPC. The IPTW-adjusted multivariate model revealed that the unfavorable group had a negative impact on OS in mCRPC patients [hazards ratio (HR) 2.98, P < 0.001]. CONCLUSIONS: Higher PSA nadir and shorter TTN during the initial ADT are poor prognostic factors in patients with mCRPC.

BACKGROUND: The impact of preoperative renal impairment severity on prognosis in urothelial carcinoma remains unelucidated. OBJECTIVE: To evaluate the impact of severe preoperative renal insufficiency on oncological outcomes in patients with urothelial carcinoma who underwent radical cystectomy or nephroureterectomy. DESIGN, SETTING, AND PARTICIPANTS: A total of 1066 patients with urothelial carcinoma who underwent radical cystectomy or nephroureterectomy at six medical centres from February 1995 to November 2017 were retrospectively examined. OUTCOME MEASUREMENTS AND STATISTICAL ANALYSIS: Oncological outcomes, stratified using preoperative estimated glomerular filtration rate (eGFR≥60, 45≤eGFR<60, and eGFR<45ml/min/1.73m2), were investigated. Inverse probability of treatment weighting (IPTW)-adjusted Cox proportional hazard regression analysis was performed to evaluate the impact of preoperative eGFR on prognosis. RESULTS AND LIMITATIONS: Of 610 patients with muscle-invasive bladder cancer (MIBC), 80 (13%) had severe renal insufficiency (eGFR<45ml/min/1.73m2). Of 456 patients with upper tract urothelial carcinoma (UTUC), 101 (22%) had severe renal insufficiency. Significant differences were noted in background and prognosis among the patients with preoperative eGFR≥60, 45≤eGFR<60, and eGFR<45ml/min/1.73m2. Findings of IPTW-adjusted Cox regression analysis demonstrated that preoperative eGFR<45ml/min/1.73m2 was significantly associated with poor postsurgical recurrence-free, cancer-specific and overall survival rates in patients with either MIBC or UTUC. CONCLUSIONS: Patients with urothelial carcinoma with preoperative eGFR<45ml/min/1.73m2 had a significantly lower survival probability than those without. PATIENT SUMMARY: In this report, we found that preoperative severe renal insufficiency (estimated glomerular filtration rate<45ml/min/1.73m2) had higher risk for relapse and lower survival probability. Close attention is necessary when urothelial carcinoma patients have severe renal insufficiency before radical cystectomy or nephroureterectomy.

PURPOSE: To investigate the association between the Geriatric Nutritional Risk Index (GNRI) and prognosis of patients with metastatic hormone-naïve prostate cancer (mHNPC) and to design the optimal risk score predicting for prognosis. METHODS: We retrospectively reviewed data from the Michinoku Japan Urological Cancer Study Group database, containing information about 656 patients with mHNPC who initially received androgen-deprivation therapy between 2005 and 2017. The baseline GNRI was calculated using serum albumin level and body mass index. Poor nutrition was defined as GNRI < 92.0. The impact of GNRI, CHAARTED criteria, and laboratory parameters on oncological outcomes was investigated using the multivariable Cox regression models. We developed the risk comprising GNRI and laboratory parameters and compared its prognostic performance with the CHAARTED criteria using the receiver operating characteristic curve with the DeLong method. RESULTS: Of 339 patients with sufficient data, 66 (19%) were diagnosed with poor nutrition. Multivariate analyses showed that GNRI < 92.0 was an independent prognostic factor of cancer-specific survival [hazard ratio (HR) 1.76; 95% confidence interval (CI) 1.04-2.98, P = 0.035] and overall survival (HR 1.80; 95% CI 1.13-2.89, P = 0.013), in addition to hemoglobin (Hb) and lactic dehydrogenase (LDH) levels. We designed the risk score comprising GNRI < 92.0, Hb < 13.0 g/dL, and LDH > 222 IU/L. The predictive value of the risk score was significantly superior to that of the CHAARTED criteria. CONCLUSIONS: Poor nutrition may predict mortality in patients with mHNPC. Risk factors, such as nutritional status and laboratory parameters, may be useful in decision-making regarding aggressive treatments for patients with mHNPC.
