Diagnostic Value of the Vesical Imaging-Reporting and Data System in Bladder Urothelial Carcinoma with Variant Histology. Eur Urol Oncol 2023; 6:99-102. [PMID: 35933266 DOI: 10.1016/j.euo.2022.07.006] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/11/2022] [Revised: 07/08/2022] [Accepted: 07/20/2022] [Indexed: 11/18/2022]
Abstract
The value of the Vesicle Imaging-Reporting and Data System (VI-RADS) in the diagnosis of muscle-invasive bladder cancer (MIBC) for urothelial carcinoma with variant histology (VUC) remains unknown. We retrospectively evaluated 360 consecutive patients with bladder cancer (255 pure urothelial carcinoma [PUC] and 69 VUC) who underwent multiparametric magnetic resonance imaging between 2011 and 2019. VI-RADS scores assigned by four readers were significantly higher for the VUC group than for the PUC group (p < 0.05). In the cohort of 122 pair-matched patients, there was no significant difference in VI-RADS score distribution between the PUC and VUC groups for all readers (p > 0.05). The area under the receiver operating characteristic curve for MIBC diagnosis via overall VI-RADS score was 0.93-0.94 for PUC and 0.89-0.92 for VUC, with no significant difference between the PUC and VUC groups (p = 0.32-0.60). These data suggests that VI-RADS scores achieved high diagnostic performance for detection of muscle invasion in both PUC and VUC. PATIENT SUMMARY: The Vesical Imaging-Reporting and Data System (VI-RADS) is a standardized system for reporting on detection of muscle-invasive bladder cancer via magnetic resonance imaging (MRI) scans. Our study shows that VI-RADS is also highly accurate for diagnosis for different variants of muscle-invasive bladder cancer, with good inter-reader agreement.

The role of multimodal salvage therapy in the management of recurrent adrenocortical carcinoma. Jpn J Clin Oncol 2023; 53:436-442.

Abstract
BACKGROUND Adrenocortical carcinoma is an aggressive tumor which often recurs despite apparent complete resection. This study assessed the long-term outcomes for patients with recurrent adrenocortical carcinoma after multimodal salvage therapy with chemotherapy, chemoradiotherapy and surgery. METHODS We retrospectively reviewed medical records of patients who had a pathological diagnosis of adrenocortical carcinoma between 1996 and 2017. Kaplan-Meier curves were used to assess progression-free and cancer-specific survivals among all patients and cancer-specific survival among patients with tumor recurrence. Log-rank test was used to compare patient survivals by modality of salvage therapy (chemotherapy, chemoradiotherapy and chemotherapy/chemoradiotherapy plus surgery). RESULTS Of 20 patients who underwent initial surgery, recurrence occurred in 14 (70%) with a median interval of 7.5 (range 1.0-12.6) months. Salvage therapy provided was chemotherapy only (n = 7), chemoradiotherapy (n = 2) and chemotherapy/chemoradiotherapy plus surgery (n = 5). Of the five patients who received salvage surgery, three underwent repeated resections. The potential benefit of multimodal salvage therapy was suggested in five patients (4 with chemotherapy/chemoradiotherapy plus surgery and 1 with chemoradiotherapy) who achieved durable disease control (cancer-specific survival from initial recurrence, 22-258 months). With a median follow-up of 25 months from recurrence, the 5-year cancer-specific survival rate was 58%. cancer-specific survival after recurrence was prolonged in patients with ≤ stage 3 disease, positive response to chemotherapy/chemoradiotherapy and salvage surgery. CONCLUSIONS Long-term disease control and survival could be achieved in highly selected patients with recurrent adrenocortical carcinoma using a multidisciplinary approach. Patients who had relatively limited recurrent sites and responded well to chemotherapy/chemoradiotherapy may be considered for salvage surgery on a case-by-case basis.

Abstract
OBJECTIVES Accurately predicting of progression is important for patients with non-muscle-invasive bladder cancer (NMIBC). We previously reported that bladder neck involvement (BNI) was significantly associated with progression of NMIBC. In this study, we evaluated the prognostic significance of the detailed BNI location in NMIBC patients. METHODS We retrospectively reviewed 651 patients diagnosed with primary NMIBC at a single center between 2000 and 2018. Using the detailed BNI location, patients were divided into the following three groups: dorsal BNI (BNId; 4 to 8 o'clock position), ventral BNI (BNIv; 8 to 4 o'clock but not 4 to 8 o'clock position), and non-BNI group. Both time to progression to muscle-invasive disease and distant metastasis was compared among the three groups. A prognostic model was developed and its discriminative ability was evaluated. RESULTS Dorsal bladder neck involvement and BNIv were observed in 43 (6.6%) and 36 (5.5%) patients, respectively. During a median follow-up of 61 months, 35 (5.4%) patients progressed. The cumulative incidence at 5 years was 12%, 0%, and 5.0% in BNId, BNIv, and non-BNI groups, respectively. On multivariate analysis, BNId was a significant and independent risk factor for progression, tumor stage pT1, and histologic grade G3. One point was assigned to each factor, and patients were classified into four well-stratified prognostic groups based on the total score. CONCLUSION Dorsal bladder neck involvement was an independent and significant risk factor for progression in primary NMIBC. Our simple and practical prognostic model including BNId is easy to use and may help selecting the optimal treatment and its timing.

Abstract
Background Unexpected adverse pathology is a major concern in surgical management of clinically localised renal cell carcinoma (RCC). Further studies are needed to improve preoperative risk stratification. Objective To define and classify tumour shape irregularity (TSI) based on preoperative imaging, and to investigate its effect on pathological and oncological outcomes in clinically localised RCC. Design setting and participants We retrospectively analysed 474 patients with cT1-2N0M0 RCC managed by partial or radical nephrectomy. Preoperative dynamic computed tomography was used to define and classify TSI, graded as 1 (completely elliptical shape), 2 (elliptical shape with minor and focal protrusions), or 3 (nonelliptical shape presenting with major and/or extensive protrusions). Intervention Partial or radical nephrectomy. Outcome measurements and statistical analysis A logistic regression analysis evaluated the risk factors for pT3a upstaging and Fuhrman grade 3-4. A Cox proportional hazard analysis assessed preoperative variables for recurrence-free survival (RFS). Results and limitations The median tumour size was 3.5 cm, and 94 patients (20%) had (R)adius (tumour size as maximal diameter), (E)xophytic/endophytic properties of tumour, (N)earness of tumour deepest portion to collecting system or sinus, (A)nterior (a)/posterior (p) descriptor, and (L)ocation relative to polar lines (RENAL) score ≥10. TSI was graded as 1, 2, and 3 in 214 (45%), 151 (32%), and 109 (23%) patients, respectively. Higher TSI was significantly associated with a larger tumour size and a higher RENAL score. Overall, pT3a upstaging and Fuhrman grade 3-4 were observed in 45 (9.5%) and 116 patients (31% in 380 clear cell RCC cases), respectively. The incidence of pT3a upstaging and Fuhrman grade 3-4 was significantly higher in patients with higher TSI (0.5%, 8.6%, and 28% for pT3a upstaging and 12%, 33%, and 60% for Fuhrman grade 3-4 in TSI 1, 2, and 3 groups, respectively). In multivariable analyses, higher TSI was independently associated with adverse pathological outcomes. During the median follow-up of 6.0 yr, 49 patients (10%) developed recurrence. Multivariable analyses demonstrated that older age and higher TSI were independent risk factors for worse RFS. The limitations include the retrospective design. Conclusions TSI may be a useful adjunct in preoperative risk stratification for adverse pathology and recurrence after surgery in clinically localised RCC. Patient summary Tumour shape irregularity is significantly associated with unfavourable pathological outcomes, that is, locally advanced stage or high-grade cancer, and with a higher recurrence rate after surgery in patients with clinically localised renal cell carcinoma. Preoperative evaluation of the tumour shape may help in patient counselling and treatment decisions.

Abstract
INTRODUCTION We sought to determine whether loss of renal function increases risk of recurrence and metastases in renal cell carcinoma (RCC), and whether this impact was age-related. MATERIALS AND METHODS We performed a retrospective analysis of the International Marker Consortium for Renal Cancer (INMARC) registry. Patients were separated into younger (<65 years old) and elder (≥65 years old) age groups, and rates of de novo estimated glomerular filtration rate (eGFR<45 mL/min/1.73m2 [eGFR<45]) were calculated. Multivariable analysis (MVA) was conducted for predictors of progression-free survival (PFS) and all-cause mortality (ACM). Kaplan-Meier Analysis (KMA) was conducted for PFS and overall survival (OS) in younger and elder age groups stratified by functional status. RESULTS We analyzed 1805 patients (1113 age<65, 692 age≥65). On MVA in patients <65, de novo eGFR<45 was independently associated with greater risk for worsened progression (HR=1.61, P=.038) and ACM (HR=1.82, P=.018). For patients ≥65, de novo eGFR<45 was not independently associated with progression (P=.736), or ACM (P=.286). Comparing patients with de novo eGFR<45 vs. eGFR ≥45, KMA demonstrated worsened 5-year PFS and OS in patients <65 (PFS: 68% vs. 86%, P<.001; OS: 73% vs. 90%, P<.001), while in patients ≥65, only 5-year OS was worsened (77% vs. 81%, P<.021). CONCLUSION Development of de novo eGFR<45 was associated with more profound impact on patients <65 compared to patients ≥65, being an independent risk factor for PFS and ACM. The mechanisms of this phenomenon are unclear but underscore desirability for nephron preservation when safe and feasible in younger patients.

Abstract
Pheochromocytomas (PCCs) and paragangliomas (PGLs) are non-epithelial neuroendocrine neoplasms originating from the adrenal medulla and paraganglion of the sympathetic and parasympathetic nervous system, respectively. PCCs and PGLs show histological similarities with other epithelial neuroendocrine neoplasms and olfactory neuroblastomas (ONBs), and the differential diagnosis of PGLs is particularly difficult. Therefore, we compared the sensitivity of PHOX2A, PHOX2B, and tyrosine hydroxylase (TH) in the histopathological diagnosis of PCCs and PGLs immunohistochemically using the tissue microarrays of 297 neoplasms including PCCs, PGLs, neuroblastomas, ganglioneuromas, epithelial neuroendocrine neoplasms, and ONBs. Using cutoff values of 25%, 5%, and 5% of tumor cells expressing PHOX2A, PHOX2B, and TH, respectively, as positive, 40 of 51 PCCs, 32 of 33 parasympathetic/head and neck PGLs (HNPGLs), 17 of 19 sympathetic/thoracoabdominal PGLs (TAPGLs), and 12 of 152 epithelial neuroendocrine neoplasms, including 123 well-differentiated and 29 poorly differentiated neuroendocrine neoplasms, were PHOX2A-positive. All 51 PCCs, 33 HNPGLs, and 19 TAPGLs were PHOX2B-positive, while all 152 epithelial neuroendocrine neoplasms were PHOX2B-negative. Moreover, 50 of 51 PCCs, 13 of 33 HNPGLs, all TAPGLs, and 12 of 152 epithelial neuroendocrine neoplasms were TH-positive. All ONBs were negative for PHOX2A, PHOX2B, and TH. PHOX2B was the most sensitive and specific diagnostic marker for PCCs and PGLs among PHOX2A, PHOX2B, and TH. PHOX2B can facilitate identification of PCCs and PGLs from epithelial neuroendocrine neoplasms and ONBs, especially in the case of HNPGLs, in which TH is often negative.

Abstract
Background Several markers of inflammation have been associated with oncologic outcomes. Prognostic markers are not well-defined for renal cell carcinoma (RCC). We sought to investigate the association of preoperative neutrophil-lymphocyte ratio (NLR), platelet-lymphocyte ratio (PLR), and De Ritis ratio with mortality in RCC. Methods Multi-center retrospective analysis of patients undergoing surgery for RCC. Primary outcome of interest was all-cause mortality (ACM). Secondary outcomes were non-cancer mortality (NCM) and cancer-specific mortality (CSM). Elevated NLR was defined as ≥2.27, elevated PLR as ≥165, and elevated De Ritis ratio as ≥ 2.72. Multivariable cox regression analysis (MVA) was conducted to elucidate risk factors for primary and secondary outcomes, and Kaplan-Meier analysis (KMA) was used to evaluate survival outcomes comparing elevated and non-elevated NLR, PLR, and De Ritis ratio. Results 2656 patients were analyzed (874 patients had elevated NLR; 480 patients had elevated PLR and 932 patients had elevated De Ritis). Elevated NLR was a significant predictor of ACM (HR 1.32, 95% CI: 1.07-1.64, p=0.003) and NCM (HR 1.79, 95% CI: 1.30-2.46, p<0.001) in MVA. Elevated De Ritis was a significant predictor of ACM (HR 2.04, 95% CI: 1.65-2.52), NCM (HR 1.84, 95% CI: 1.33-2.55, p<0.001), and CSM (HR 1.97, 95% CI:1.48-2.63, p<0.001). KMA revealed significant difference in 5-year overall survival (OS) (48% vs. 68%, p<0.001), non-cancer survival (NCS) (69% vs. 87%, p<0.001), and cancer-specific survival (CSS) (60% vs. 73%, p<0.001) for elevated versus non-elevated NLR. For PLR, there was a difference in 5-year OS (51% vs. 61%, p<0.001) and CSS (60% vs. 73%, p<0.001) with KMA. Conclusions Elevated NLR was independently associated with worse ACM and NCM, while elevated De Ritis was predictive for CSM in addition to ACM and NCM. These differences may be useful in refining risk stratification with respect to cancer-related and non-cancer mortality in RCC patients and deserve further investigation.

Abstract
A mycotic aneurysm after intravesical instillation of bacillus Calmette-Guérin (BCG) for early-stage bladder cancer is a rare, but life-threatening, complication. In the present report, we have described the case of a patient who had undergone endovascular aneurysm repair for a rapidly growing saccular abdominal aortic aneurysm after BCG therapy. Three months after endovascular aneurysm repair, the patient had developed an abscess that required open surgery. Cultures from a blood sample and the abscess revealed Mycobacterium bovis BCG. A mycotic aneurysm due to BCG therapy should be suspected in patients with a history of BCG treatment. Such patients should immediately start antitubercular therapy.

Abstract
INTRODUCTION SDH Gene mutation is known to be a common cause of pheochromocytoma/paraganglioma and renal cell carcinoma. Here, we report a case of succinate dehydrogenase B-deficient paraganglioma, which has a high risk of metastasis and recurrence, complicated by succinate dehydrogenase-deficient renal cell carcinoma, which is rare and accounts for approximately 0.1% of all renal cell carcinomas. CASE PRESENTATION A 50-year-old man underwent en bloc resection of a retroperitoneal tumor and the right kidney for retroperitoneal paraganglioma and right renal tumor. Both tumors showed negative expressions of succinate dehydrogenase B in immunostaining. The patient was diagnosed with succinate dehydrogenase-deficient paraganglioma and succinate dehydrogenase-deficient renal cell carcinoma. Seventeen months later, retroperitoneal lymphadenectomy revealed lymph node metastasis of the paraganglioma. Deletion of the SDHB gene was revealed by genome sequencing of the lymph node. CONCLUSION This is the first reported case of synchronously diagnosed succinate dehydrogenase-deficient paraganglioma and succinate dehydrogenase-deficient renal cell carcinoma.

Abstract
BACKGROUND AND PURPOSE Despite advances in molecular imaging, preoperative diagnosis of astrocytomas and oligodendrogliomas can be challenging. In the present study, we assessed whether 7T SWI can be used to distinguish astrocytomas and oligodendrogliomas and whether malignant grading of gliomas is possible. MATERIALS AND METHODS 7T SWI was performed on 21 patients with gliomas before surgery with optimization for sharp visualization of the corticomedullary junction. Scoring for cortical thickening and displacement of medullary vessels, characteristic of oligodendroglial tumors, and cortical tapering, characteristic of astrocytic tumors, was performed. Additionally, characteristics of malignancy, including thickening of the medullary veins, the presence of microbleeds, and/or necrosis were scored. RESULTS Scoring for oligodendroglial (highest possible score, +3) and astrocytic (lowest score possible, -3) characteristics yielded a significant difference between astrocytomas and oligodendrogliomas (mean, -1.93 versus +1.71, P < .01). Scoring for malignancy was significantly different among the World Health Organization grade II (n = 10), grade III (n = 4), and grade IV (n = 7) tumors (mean, 0.20 versus 1.38 versus 2.79). Cortical thickening was observed significantly more frequently in oligodendrogliomas (P < .02), with a sensitivity of 71.4% and specificity of 85.7%; observation of tapering of the cortex was higher in astrocytomas (P < .01) with a sensitivity of 85.7% and specificity of 100%. CONCLUSIONS Visualization of the corticomedullary junction by 7T SWI was useful in distinguishing astrocytomas and oligodendrogliomas. Observation of tapering of the cortex was most sensitive and specific for diagnosing astrocytomas. Reliably predicting malignant grade was also possible by 7T SWI.

Abstract
Abstract
Background
Cardiac calmodulinopathy is a life-threatening arrhythmia syndrome which presents several phenotypes of inherited primary arrhythmia syndrome (IPAS), and caused by mutations in calmodulin-encoded genes (CALM1–3). We aimed clarify the frequency and their clinical characteristics of calmodulinopathy in our IPAS cohort.
Methods
By using next generation sequencing, we screened arrhythmia related genes including calmodulin-encoding genes in 322 unrelated symptomatic children (0–12 years) who were suspected as IPAS; they included 40 cases with lethal arrhythmic attacks (LAE) under 6-year-old. After gene screening, we investigated their physiological and clinical characteristics about mutation carriers.
Results
Among 322 children, we identified 6 mutations of calmodulin-encoded genes in 9 probands (2.8%); one CALM1 in 2 probands (N98S), and 5 CALM2 in 7 probands (E46K, D96V, D96G, N98S, E141K). Their clinical diagnoses were long QT syndrome (LQTS, n=4), catecholaminergic polymorphic ventricular tachycardia (CPVT, n=3) and both (n=2). Their age of diagnosis ranges at 0–9 with the median of 5 years. There were three major clinical phenotypes; 1) CALM2-D96V, and E141K: two infants with advanced atrio-ventricular block, significant QTc prolongation, severe heart failure from their fetal period – both of them deceased within 1.5-year-old. Their clinical phenotypes resembled classical Timothy syndrome caused by CACNA1C mutations. 2) CALM1-N98S (n=2), CALM2-N98S (n=2), and CALM2-D96G: four preschoolers with LAEs and one syncope: all of them were 3–5 years old. In addition, a T wave morphology of CALM2-D96G carrier was very similar to LQT1. 3) CALM2-E46K (n=2): two were first diagnosed with neurological and developmental disorders, and showed phenotype of CPVT: their cardiac phenotypes were milder compared with that of 1) or 2). Overall, these phenotypes seemed to be mutation specific (indicated in figure). Their cardiac features were severer, and the onset of LAEs was earlier compared with other genotypes of LQTS/CPVT. As the treatment, β-blocker was effective for control of LAEs.
Conclusion
Cardiac calmodulinopathy presented serious and potentially lethal phenotypes in fetus or infancy. To prevent cardiac death in them, we must correctly diagnose and start the treatment as earlier as possible.

Abstract
BACKGROUND Literature lacks clear evidence regarding the optimal treatment for non-muscle-invasive micropapillary bladder cancer (MPBC) due to its rarity and the presence of only small sample size and single-centre studies. OBJECTIVE To assess cancer-specific mortality (CSM) and overall mortality (OM) between immediate radical cystectomy (RC) and conservative management among T1 high-grade (HG) MPBC. DESIGN, SETTING, AND PARTICIPANTS We retrospectively analysed a multicentre dataset including 119 T1 HG MPBC patients treated between 2005 and 2019 at 15 tertiary referral centres. The median follow-up time was 35 mo (interquartile range: 19-64). INTERVENTION Patients underwent immediate RC versus conservative management with bacillus Calmette-Guérin. OUTCOMES MEASUREMENTS AND STATISTICAL ANALYSIS Cumulative incidence functions and Kaplan-Meier methods were applied to estimate survival outcomes. Multivariable Cox analyses were performed to assess independent predictors of disease recurrence and disease progression after conservative management; covariates consisted of pure MPBC, concomitant lymphovascular invasion (LVI), and carcinoma in situ at initial diagnosis. RESULTS AND LIMITATIONS Immediate RC and conservative management were performed in 27% and 73% of patients, respectively. CSM and OM did not differ significantly among patient treated with immediate RC versus conservative management (Pepe-Mori test p = 0.5 and log-rank test p = 0.9, respectively). Overall, 66.7% and 34.5% of patients experienced disease recurrence and disease progression after conservative management, respectively. At multivariable Cox analyses, concomitant LVI was an independent predictor of disease recurrence (p = 0.01) and progression (p = 0.03), while pure MPBC was independently associated with disease progression (p = 0.03). The absence of a centralised re-review and the retrospective design represent the main limitations of our study. CONCLUSIONS Conservative management could achieve satisfactory results among T1 HG MPBC patients with neither pure MPBC nor LVI at initial diagnosis. PATIENT SUMMARY Bacillus Calmette-Guérin seems to be an effective therapy for T1 micropapillary bladder cancer patients with neither pure micropapillary disease nor lymphovascular invasion at initial diagnosis.

Association of C-reactive protein with efficacy of avelumab plus axitinib in advanced renal cell carcinoma: long-term follow-up results from JAVELIN Renal 101. ESMO Open 2022; 7:100564. [PMID: 36037566 PMCID: PMC9588905 DOI: 10.1016/j.esmoop.2022.100564] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/22/2022] [Revised: 07/13/2022] [Accepted: 07/15/2022] [Indexed: 11/17/2022] Open
Abstract
Background C-reactive protein (CRP) is an important prognostic and predictive factor in advanced renal cell carcinoma (aRCC). We report the association of CRP levels at baseline and early after treatment with efficacy of avelumab plus axitinib or sunitinib from the phase III JAVELIN Renal 101 trial. Patients and methods Patients were categorized into normal (baseline CRP <10 mg/l), normalized (baseline CRP ≥10 mg/l and ≥1 CRP value decreased to <10 mg/l during 6-week treatment), and non-normalized (CRP ≥10 mg/l at baseline and during 6-week treatment) CRP groups. Progression-free survival and best overall response from the second interim analysis and overall survival (OS) from the third interim analysis were assessed. Results In the avelumab plus axitinib and sunitinib arms, respectively, 234, 51, and 108 patients and 232, 36, and 128 patients were categorized into normal, normalized, and non-normalized CRP groups. In respective CRP groups, objective response rates [95% confidence interval (CI)] were 56.0% (49.4% to 62.4%), 66.7% (52.1% to 79.2%), and 45.4% (35.8% to 55.2%) with avelumab plus axitinib and 30.6% (24.7% to 37.0%), 41.7% (25.5% to 59.2%), and 19.5% (13.1% to 27.5%) with sunitinib; complete response rates were 3.8%, 11.8%, and 0.9% and 3.0%, 0%, and 1.6%, respectively. Median progression-free survival (95% CI) was 15.2 months (12.5-21.0 months), not reached (NR) [11.1 months-not estimable (NE)], and 7.0 months (5.6-9.9 months) with avelumab plus axitinib and 11.2 months (8.4-13.9 months), 11.2 months (6.7-13.8 months), and 4.2 months (2.8-5.6 months) with sunitinib; median OS (95% CI) was NR (42.2 months-NE), NR (30.4 months-NE), and 23.0 months (18.4-33.1 months) and NR (39.0 months-NE), 39.8 months (21.7-NE), and 19.1 months (16.3-25.3 months), respectively. Multivariate analyses demonstrated that normalized or non-normalized CRP levels were independent factors for the prediction of objective response rate or OS, respectively, with avelumab plus axitinib. Conclusions In patients with aRCC, CRP levels at baseline and early after treatment may predict efficacy with avelumab plus axitinib. C-reactive protein is an important prognostic and predictive factor in advanced renal cell carcinoma. The association between C-reactive protein levels and the efficacy of avelumab plus axitinib or sunitinib was evaluated. C-reactive protein levels at baseline and early after treatment might predict efficacy with avelumab plus axitinib.

Utility of radiomics features of diffusion-weighted magnetic resonance imaging for differentiation of fat-poor angiomyolipoma from clear cell renal cell carcinoma: model development and external validation. Abdom Radiol (NY) 2022; 47:2178-2186. [PMID: 35426498 DOI: 10.1007/s00261-022-03486-5] [Citation(s) in RCA: 8] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/19/2021] [Revised: 03/02/2022] [Accepted: 03/04/2022] [Indexed: 11/29/2022]
Abstract
PURPOSE To investigate the utility of radiomics features of diffusion-weighted magnetic resonance imaging (DW-MRI) to differentiate fat-poor angiomyolipoma (fpAML) from clear cell renal cell carcinoma (ccRCC). MATERIALS AND METHODS This multi-institutional study included two cohorts with pathologically confirmed renal tumors: 65 patients with ccRCC and 18 with fpAML in the model development cohort, and 17 with ccRCC and 13 with fpAML in the external validation cohort. All patients underwent magnetic resonance imaging (MRI) including DW-MRI. Radiomics analysis was used to extract 39 imaging features from the apparent diffusion coefficient (ADC) map. The radiomics features were analyzed with unsupervised hierarchical cluster analysis. A random forest (RF) model was used to identify radiomics features important for differentiating fpAML from ccRCC in the development cohort. The diagnostic performance of the RF model was evaluated in the development and validation cohorts. RESULTS The cases in the developmental cohort were classified into three groups with different frequencies of fpAML by cluster analysis of radiomics features. RF analysis of the development cohort showed that the mean ADC value was important for differentiating fpAML from ccRCC, as well as higher-texture features including gray-level run length matrix (GLRLM)_long-run low gray-level enhancement (LRLGE), and GLRLM_low gray-level run emphasis (LGRE). The area under the curve values of the development [0.90, 95% confidence interval (CI) 0.80-1.00] and validation cohorts (0.87, 95% CI 0.74-1.00) were similar (P = 0.91). CONCLUSION The radiomics features of ADC maps are useful for differentiating fpAML from ccRCC.

Disparities in Cancer Specific and Overall Survival Outcomes in African Americans With Renal Cell Carcinoma: Analysis From the International Marker Consortium for Renal Cancer (INMARC). Urology 2022; 163:164-176. [PMID: 34995562 DOI: 10.1016/j.urology.2021.12.022] [Citation(s) in RCA: 2] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/01/2021] [Revised: 11/20/2021] [Accepted: 12/22/2021] [Indexed: 11/26/2022]
Abstract
OBJECTIVE To investigate association of African-American race and survival in Renal Cell Carcinoma (RCC). PATIENTS AND METHODS We queried the International Marker Consortium for Renal Cancer database for patients who underwent partial or radical (RN) nephrectomy. The cohort was divided into African American (AA) and non-African American (NAA) patients. Primary outcome was all-cause mortality. Secondary outcome was cancer-specific mortality. Multivariable Analysis and Kaplan-Meier Analysis were used to elucidate predictive factors and survival outcomes. RESULTS Three thousand eight hundred and ninety-three patients were analyzed (AA, n = 564/NAA, n = 3329). AA had greater Stage I (73.8% vs 63.9%, P <.001) and papillary RCC (29.8% vs 8.5%, P <.001). Multivariable Analysis revealed increasing age (HR = 1.03, P <.001), AA (HR = 1.24, P = .027), higher stage (HR = 1.30-3.19, P <.001), RN (HR = 2.45, P <.001), clear cell (HR = 1.23, P <.001), positive margin (HR = 1.34, P .004), and high-grade (HR = 1.58, P <.001) to be associated with worsened all-cause mortality. Increasing age (HR = 1.02, P <.001), AA (HR = 1.48, P = .025), RN (HR = 2.98, P <.001), high-grade (HR = 3.11, P <.001), and higher stage (HR = 3.03-13.2, P <.001) were predictive for cancer-specific mortality. Kaplan-Meier Analysis revealed worsened 5-year overall survival for AA in stage I (80% vs 88%, P = .001), stage III (26% vs 70%, P = .001), and stage IV (23% vs 44%, P = .009). Five-year cancer-specific survival was worse for AA in stage III (36% vs 81%, P <.001) and stage IV (30% vs 49%, P = .007). CONCLUSION Despite presenting with more indolent histology and lower stage, African-Americans were at greater risk for diminished survival, faring worse in overall survival for all stages and cancer-specific survival in for stage III/IV RCC. Further investigation into factors associated with these disparities is warranted.

Abstract
BACKGROUND Retrocaval ureter is a rare congenital anomaly resulting from anomalous development of inferior vena cava (IVC) and not from anomalous of the ureter. The anomaly always occurs on the right side due to regression of right supracardinal vein and persistence of right posterior cardinal vein. Retrocaval ureter tends to be associated with various vena cava anomalies because of the embryogenesis. We aimed to identify the prevalence of associated congenital venous anomalies (CVA) resulting from cardinal vein development in adults with retrocaval ureter using computed tomography (CT) images. MATERIALS AND METHODS The study included 22 adults with retrocaval ureter. We evaluated CT findings and determined the incidence of associated CVA using thin slice data sets from CT scanner with 64 or more detectors. We compared the prevalence of CVA in the retrocaval ureter group (mean age: 57±19 years) and in the control group of 6189 adults with normal ureter (mean age: 66±14 years). RESULTS In the retrocaval ureter group, 4 adults (18.2 %) had CVA including double IVC, right double IVC, preisthmic IVC with horseshoe kidney, and preaortic iliac confluence. One of 2 adults with preaortic iliac confluence had right double right IVC. In the control group, 49 adults (0.79%) had CVA including 37 double IVCe, 11 left IVCe, and 1 IVC interruption azygos continuation. Fifteen horseshow kidneys were found. The prevalence of associated CVA in the retrocaval ureter group was higher than that in the control group (p<0.001). CONCLUSIONS Retrocaval ureter is frequently associated with CVA. Various CVA with retrocaval ureter could happen because of abnormal development of not only the right posterior or supra cardinal vein but also other cardinal veins.

Efficacy and safety of avelumab plus axitinib in elderly patients with advanced renal cell carcinoma: extended follow-up results from JAVELIN Renal 101. ESMO Open 2022; 7:100450. [PMID: 35397432 PMCID: PMC9058903 DOI: 10.1016/j.esmoop.2022.100450] [Citation(s) in RCA: 15] [Impact Index Per Article: 7.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/02/2021] [Revised: 02/06/2022] [Accepted: 02/16/2022] [Indexed: 11/12/2022] Open
Abstract
Background In the phase III JAVELIN Renal 101 trial, first-line avelumab plus axitinib demonstrated a progression-free survival (PFS) and objective response rate (ORR) benefit versus sunitinib in patients with advanced renal cell carcinoma (aRCC). However, efficacy in elderly patients remains unclear. We report efficacy and safety by age group from the second interim analysis of overall survival (OS). Patients and methods PFS and ORR as per blinded independent central review (RECIST 1.1), OS, and safety were assessed in patient groups aged <65, ≥65 to <75, and ≥75 years. Results In the avelumab plus axitinib and sunitinib arms, 271/138/33 and 275/128/41 patients aged <65, ≥65 to <75, and ≥75 years, respectively, were randomized. At data cut-off (January 2019), median PFS [95% confidence interval (CI)] with avelumab plus axitinib versus sunitinib in these respective age groups was 11.6 (8.4-19.4) versus 6.9 (5.6-8.4) months [hazard ratio (HR), 0.63; 95% CI 0.501-0.786], 13.8 (11.1-18.0) versus 11.0 (7.8-16.6) months (HR, 0.88; 95% CI 0.627-1.231), and 13.8 [7.0-not estimable (NE)] versus 9.8 (4.3-NE) months (HR, 0.76; 95% CI 0.378-1.511). Median OS (95% CI) in the respective age groups was not reached (NR) (NE-NE) versus 28.6 (25.5-NE) months (HR, 0.74; 95% CI 0.541-1.022), 30.0 (30.0-NE) versus NR (NE-NE) months (HR, 0.89; 95% CI 0.546-1.467), and 25.3 (19.9-NE) versus NR (19.4-NE) months (HR, 0.87; 95% CI 0.359-2.106). ORR (95% CI) in the respective age groups was 49.4% (43.3% to 55.6%) versus 27.3% (22.1% to 32.9%), 60.9% (52.2% to 69.1%) versus 28.9% (21.2% to 37.6%), and 42.4% (25.5% to 60.8%) versus 22.0% (10.6% to 37.6%). In the avelumab plus axitinib arm, grade ≥3 adverse events (AEs) and immune-related AEs occurred in 76.9%/81.2%/72.7% and 45.5%/48.1%/36.4% in the respective age groups. Conclusions First-line avelumab plus axitinib demonstrated favorable efficacy across age groups, including patients aged ≥75 years. OS data were still immature; follow-up is ongoing. The safety profile was generally consistent across age groups. Elderly patients experience a decline in immune activity that might affect response to immunotherapy. We evaluated avelumab plus axitinib versus sunitinib by age group in patients with aRCC. Avelumab plus axitinib had favorable efficacy versus sunitinib across age groups, including patients aged ≥75 years. The safety profile was generally consistent among age groups treated with avelumab plus axitinib or sunitinib.

Abstract
Preoperative imaging differentiation between ChRCC and RO is difficult with conventional subjective evaluation, and the development of quantitative analysis is a clinical challenge. Forty-nine patients underwent partial or radical nephrectomy preceded by MRI and followed by pathological diagnosis with ChRCC or RO (ChRCC: n = 41, RO: n = 8). The whole-lesion volume of interest was set on apparent diffusion coefficient (ADC) maps of 1.5T-MRI. The importance of selected texture features (TFs) was evaluated, and diagnostic models were created using random forest (RF) analysis. The Mean Decrease Gini as calculated through RF analysis was the highest for mean_ADC_value. ChRCC had a significantly lower mean_ADC_value than RO (1.26 vs. 1.79 × 10−3 mm2/s, p < 0.0001). Feature selection by the Boruta method identified the first-quartile ADC value and GLZLM_HGZE as important features. ROC curve analysis showed that there was no significant difference in the classification performances between the mean_ADC_value-only model and the Boruta model (AUC: 0.954 vs. 0.969, p = 0.236). The mean ADC value had good predictive ability for the distinction between ChRCC and RO, comparable to that of the combination of TFs optimized for the evaluated cohort. The mean ADC value may be useful in distinguishing between ChRCC and RO.

Abstract
INTRODUCTION Concurrent chemoradiotherapy is considered the standard treatment strategy for locally advanced cervical cancer. Most recent reports indicate that patients with bulky tumours or adenocarcinoma subtypes have poorer local control. Carbon-ion radiotherapy (CIRT) with the concurrent use of chemotherapy has shown promising results in such cases of difficult-to-treat uterine cervical cancer. Programmed death-ligand 1 (PD-L1) upregulation was observed in tumour tissue samples from patients who had undergone CIRT. Thus, a combination of CIRT and anti-PD-L1 antibody may suppress metastasis by activating antitumour immune response, in addition to exhibiting strong local effects. OBJECTIVE We will assess the safety and tolerability (primary endpoint) of the concomitant use of durvalumab, an anti-PD-L1 antibody, with CIRT and weekly cisplatin for locally advanced cervical cancer. METHODS AND ANALYSIS This study is a non-randomised, open-label, prospective phase 1b study. Up to 10 patients with histologically proven uterine cervical cancer at stage IIB, IIIA, IIIB, IIIC1 or IVA as per International Federation of Gynecology and Obstetrics (2018) staging will be enrolled. All patients will receive CIRT of 74.4 Gy relative biological effectiveness in 20 fractions over 5 weeks (four fractions per week). Weekly cisplatin at a dose of 40 mg/m2 will be administrated up to five times. Durvalumab at a dose of 1500 mg/body will be administrated at weeks 2 and 6. Safety and tolerability will be evaluated based on the frequency of dose-limiting toxicities until 92 days after CIRT starts. Patients will be followed-up strictly as per the scheduled protocol for 1 year after CIRT initiation. ETHICS AND DISSEMINATION The Human Research Ethics Committees of QST Hospital (#C21-002) and Chiba University (#2021006) have approved this study protocol. The findings will be published in peer-reviewed journals and presented at scientific conferences. TRIAL REGISTRATION NUMBER Japan Registry of Clinical Trials (jRCT2031210083), registered on 12 May 2021.

Abstract
325 Background: Diabetes mellitus (DM) has been hypothesized to be a risk factor for development of renal cell carcinoma (RCC). We evaluated impact of DM on survival outcomes in RCC. Methods: We performed a retrospective analysis of the International Marker Consortium for Renal Cancer (INMARC). The cohort was divided into three subgroups (patients with stage I vs. stage II vs. stage III RCC) for descriptive, survival and multivariable analysis of outcomes. Kaplan Meier Analysis (KMA) was used to compare diabetic and non-diabetic patients in the different stage subgroups to evaluate overall survival (OS), cancer-specific survival (CSS) and progression-free survival (PFS). Cox Regression multivariable analysis (MVA) was used to elucidate independent risk factors for all-cause mortality (ACM). Results: 2,927 patients with stage I RCC (709-DM/ 2218 non-DM), 2,513 with stage II RCC (688 DM/1825 non-DM) and 460 with stage 3 RCC (355 DM/ 105 non-DM) were analyzed. MVA revealed DMII having no impact on CSM (p=0.118) or PFS (p=0.316) across all stages. MVA for ACM revealed age (HR 1.026, p<0.001), male sex (HR=1.425, p<0.001), hypertension (HR=1.693, p <0.001) and tumor size (HR=1.064, p<0.001) as independent risk factors. KMA identified increased ACM in stage I (p<0.001) and stage III (p<0.001) RCC patients with non-DM compared to diabetic patients. Conclusions: Our findings suggest that DM may have impact on survival of in RCC, but this impact is mostly driven by non-oncologic, as opposed to oncologic effects. Further investigation is requisite.

Abstract
394 Background: Studies have discussed the prognostic use of C-reactive protein (CRP) and De Ritis ratio (AST/ALT or AAR) in the evaluation of renal malignant masses. Elevated pre-treatment CRP has been shown to be associated with non-cancer mortality. Additionally increased preoperative AAR has been found to be a prognostic factor for overall survival. With studies showing the ethnic disparities in mortality rate in certain underserved ethnic groups, there is a need for investigation into possible ethnic differences. Our aim is to evaluate the association between these elevated preoperative markers and all-cause mortality (ACM) and cancer specific mortality (CSM) among ethnic groups. Methods: Retrospective review of the International Marker Consortium for Renal Cancer (INMARC) was performed. Patients with renal malignancies who underwent partial or radical nephrectomy (PN, RN) were included. Patients were grouped according to ethnicity and African American (AA), White, Asian, and Hispanic ethnic groups were selected for descriptive, survival and multivariable analysis of outcomes. A Cox-regression multivariable analysis (MVA) was performed for each group. The primary outcome was overall survival and cancer specific survival from time of surgery to last follow-up, which was evaluated using Kaplan-Meyer Analysis (KMA). Results: A total of 4,810 patients were analyzed (627 AA, 2,344 White, 462 Hispanic, 1,094 Asian). Preoperative CRP and AAR were considered elevated if above 5 mg/L and 1.26, respectively. Descriptive analysis showed significant differences in age, diabetes mellitus status, hypertension status, tumor size, surgery type (PN vs. RN), preoperative CRP, preoperative AAR, ACM and CSM between ethnicities (p-value <0.001). MVA revealed elevated CRP to be predictive of ACM in AA (p<0.001, HR 2.830, 95% CI [1.728, 4.635]) and White (p<0.001, HR 2.933, 95% CI [2.272, 3.785]) patients. Elevated AAR was only predictive for all ACM in Asian (p=0.004, HR 2.546, 95% CI [1.358, 4.775]) patients. MVA showed similar results for CSM with elevated CRP found to be a significant independent risk factor for CSM in AA (p<0.001, HR 7.006, 95% CI [2.649, 18.531]) and White (p<0.001, HR 3.391, 95% CI [2.403, 4.784]) patients while elevated AAR is a significant independent risk factor for all CSM in Asian (p=0.041, HR 2.374, 95% CI [1.034, 5.448]) patients. KMA revealed statistically significant impact of elevated CRP on ACM and CSM in AA, White, and Asian patients (p<0.001). It also showed a statistically significant effect of elevated AAR in Asian patients (p<0.001). Conclusions: CRP has broad utilities in prognostic abilities for non-Asian ethnic sub-cohorts. However, AAR has predictive abilities in Asian patients. These results show the importance of using different lab markers for preoperative assessment in renal masses and the need for further research in ethnic differences in clinical presentation.

Abstract
395 Background: Radical nephrectomy (RN) is a mainstay of management of localized renal cancer larger than 4 cm in size. RN is associated with renal functional decline, however impact of age on functional decline is unclear. We investigated impact of age on post RN function, focusing on decline to moderate and severe chronic kidney disease (CKD). Methods: This was a retrospective analysis of the International Marker Consortium for Renal Cancer (INMARC) registry of patients who underwent RN. Primary outcome was development of de novo CKD stage IIIB [estimated glomerular filtration rate (eGFR)<45 mL/min/1.73m2). Secondary outcomes included de novo CKD stage III (eGFR<60) and CKD Stage IV (eGFR>30). Patients clinical characteristics were stratified by age groups (<50, 50-70 and >70 years old). Multivariable logistic regression analysis (MVA) was utilized to identify risk factors with renal functional decline to different CKD stages. Kaplan-Meier analysis (KMA) was utilized to evaluate functional outcomes with respect to the different age groups. Results: Overall, 2,436 patients were analyzed (≤50 years, n=513; 50-70 years, n=1,344; >70, n=579; median follow up 31.9 months). On MVA, increasing age was independently associated with increased risk of development of CKD Stage IIIb [compared to ≤50 years (referent), 50-70 years, OR 3.35, p<0.001 and >70 years OR 7.7, p<0.001]. In addition, increasing BMI (OR 1.029, p=0.002), coronary artery disease (OR 1.70, p=0.01), diabetes mellitus (OR 1.37, p=0.029) and African American race (OR 1.6, p=0.01) were independent risk factors for CKD stage IIIb. Increasing age was also independently associated with an increased risk of development of CKD Stage III [compared to ≤50 years (referent), 50-70 years, OR 3.4 p<0.001 and >70 years OR 9.4, p<0.001]. Increasing BMI (OR 1.032, p=0.002) and coronary artery disease (OR 1.87, p=0.015) were also risk factors for CKD stage III. Age >70 years was independently associated with increased risk of development of CKD Stage IV [OR 1.96, p=0.027]. In addition, male (OR 1.49, p= 0.036), increasing BMI (OR 1.03, p=0.003), diabetes mellitus (OR 2.69, p <0.001), and African American race (OR 2.02, p=0.002) were risk factors for CKD stage IV. Kaplan-Meier Analyses demonstrated age associated declines in 5 year freedom from CKD Stage III (≤50 years 73.9%, 50-70 years 53.7%, and >70 years 37.06%, p<0.001), CKD Stage IIIb (age ≤50 years 92.7%, 50-70 years 71.8%, and >70 years 55.5%, p<0.001) and CKD Stage IV (age ≤50 years 93.7%, 50-70 years 89.8%, and >70 years 81.2%, p< 0.001). Conclusions: Increasing age is an independent risk factor for progressive and clinically significant renal functional decline after radical nephrectomy. Prioritization for nephron sparing management should be considered whenever safe and feasible in elderly patients to reduce potential risk of sequelae of functional decline.

Abstract
JLab E12-19-002 Experiment is planned to measure the Λ-binding energies of 3ΛH [Jπ = 1/2+ or 3/2+(T = 0)] and 4ΛH (1+) at JLab Hall C. The expected accuracy for the binding-energy measurement is |ΔBtotal Λ | ≃ 70 keV. The accurate spectroscopy for these light hypernuclei would shed light on the puzzle of the small binding energy and short lifetime of 3ΛH, and the chargesymmetry breaking in the ΛN interaction. We aim to perform the experiment in 2025.

Abstract
Abstract
Face squeezing, floor heave, and buckling of invert were found after a 10-day holiday in 2014 around the serpentinite face of a tunnel in Hokkaido, Japan. The damage continued for over 2 months, extending 400 m toward the entrance causing a massive roof fall. The tunnel was excavated again with a circular section and extra-thick shotcrete, and the face had crossed the damaged part 6 years after the damage occurred. Uniaxial and triaxial compression tests were carried out to obtain the mechanical properties of the serpentinite to clarify the severe damage mechanism at the tunnel. The main experimental findings are as follows. The uniaxial compressive strength of the serpentinite samples was very low, and the ratio of the strength to the estimated overburden pressure was extremely low. The parameter n indicated that the time-dependent deformation of the serpentinite was not large but the same as ordinary rocks. All specimens showed strain-hardening in the triaxial compression test, and the friction angle was very low by the brucite content. Only primary creep was observed in the multistage triaxial creep test. The pressure on the shotcrete from rock mass for the damaged tunnel was enough to cause creep deformation and failure of shotcrete. From the above findings, designing the concrete lining that can support the earth and water pressure is recommended for tunnel excavation in such a weak serpentinite rock mass, particularly with a very low friction angle by brucite.
Highlights
Face squeezing, floor heave, and buckling of invert were found after a 10-day holiday around the serpentinite face in Hokkaido, Japan.
The time-dependent deformation of the serpentinite was not large but the same as ordinary rocks.
All specimens showed strain-hardening in the triaxial compression test, and the friction angle was very low by the brucite content.
Only primary creep was observed in the multistage triaxial creep test.
The severe damage to the tunnel was not a brittle creep failure of the serpentinite rock mass itself but the shotcrete lining.

Abstract
OBJECTIVE Primary bilateral macronodular adrenal hyperplasia (PBMAH), a rare cause of Cushing syndrome, is often diagnosed as a bilateral adrenal incidentaloma with subclinical cortisol production. Circulating microRNAs (miRNAs) are a characteristic of adrenocortical adenomas, but miRNA expression in PBMAH has not been investigated. We aimed to evaluate the circulating miRNA expression in patients with PBMAH and compare them with those in patients with non-functioning adrenocortical adenoma (NFA) and cortisol-producing adrenocortical adenoma (CPA). METHODS miRNA profiling of plasma samples from four, five, and five patients with NFA, CPA, and PBMAH, respectively, was performed. Selected miRNA expressions were validated using quantitative RT-PCR. RESULTS PBMAH samples showed distinct miRNA expression signatures on hierarchical clustering while NFA and CPA samples were separately clustered. PBMAH was distinguished from the adenoma group of NFA and CPA by 135 differentially expressed miRNAs. Hsa-miR-1180-3p, hsa-miR-4732-5p, and hsa-let-7b-5p were differentially expressed between PBMAH and adenoma (P = 0.019, 0.006, and 0.003, respectively). Furthermore, PBMAH could be classified into two subtypes based on miRNA profiling: subtype 1 with a similar profile to those of adenoma and subtype 2 with a distinct profile. Hsa-miR-631, hsa-miR-513b-5p, hsa-miR-6805-5p, and hsa-miR-548av-5p/548k were differentially expressed between PBMAH subtype 2 and adenoma (P = 0.027, 0.027, 0.027, and 1.53E-04, respectively), but not between PBMAH, as a whole, and adenoma. CONCLUSION Circulating miRNA signature was identified specific for PBMAH. The existence of subtype-based miRNA profiles may be associated with the pathophysiological heterogeneity of PBMAH.

Abstract
OBJECTIVES To report experience with focal brachytherapy (FB) and compare its clinical outcomes with those of radical prostatectomy (RP) in localized prostate cancer. METHODS Fifty-one patients with low- to intermediate-risk prostate cancer underwent low-dose-rate FB. Survival rates free from biochemical failure (BF), additional treatment (AT) including re-FB, and whole-gland or systemic salvage therapy (ST) were calculated and oncological risk factors were investigated. Patient-reported outcomes on genitourinary function were also assessed. Using propensity scoring, 51 pair-matched RP patients were selected. Oncological control, urinary continence, and ejaculation status after FB and RP were compared. RESULTS During a median 5.7-year follow-up, BF, AT, and ST occurred in 12 (24%), 10 (20%), and 4 FB patients (8%), respectively. 6 of 10 AT patients were managed with re-FB alone. In the RP cohort, 3 patients (6%) underwent ST. 5-year BF-free survival rate after FB was 79%. Compared to 5-year ST-free survival rate of 94% after RP, ST-free and AT-free survival rates after FB were 93% (P = 0.813) and 87% (P = 0.049), respectively. Multivariate analyses of FB-treated patients showed that time to PSA nadir was negatively associated with BF and AT (hazard ratio 0.84 and 0.83, respectively, P <0.001 for each). The difference in oncological outcomes between low- and intermediate-risk categories was not significant. At 2 years after FB and RP, pad-free continence rates were 100% and 81%, respectively (P = 0.001). Ejaculation was preserved in 67% and 0% of patients who had been capable of ejaculation at baseline, respectively (P <0.001). CONCLUSION In low- to intermediate-risk prostate cancer, FB-treated patients achieved superior genitourinary function compared to pair-matched RP patients. The need for ST was not substantially different between the 2 treatment cohorts. Over half of patients requiring AT could be managed by re-focal treatment rather than whole-gland ST. Early PSA nadir may predict poor oncological control after FB.

Abstract
This study investigated whether dual tasks comprising cognitive tasks and occupations related to daily living can improve the mental and cognitive function of Japanese community-dwelling older adults. Participants included 30 older adults, equally divided into intervention and control groups. The outcome measures were memory, attention, depression, and health-related quality of life. No adverse effects of the intervention were observed in any participant in the intervention group. Logical memory I, logical memory II, and Center for Epidemiologic Studies Depression Scale scores showed a significant interaction. Dual tasks combining cognitive tasks and occupations may help improve delayed recall and alleviate depression. A novel attempt to integrate cognitive stimulation and activities valued by individuals may help mediate age-related cognitive function decline and reduce depressive symptoms in community-dwelling older adults.

Abstract
AIM We aimed to explore the association between cancer cachexia phenotypes in the early phase of treatment induction and the prognosis of advanced urothelial cancer (aUC) patients receiving pembrolizumab. METHODS This retrospective study included 31 aUC patients treated with pembrolizumab as a second- or later-line therapy. Patients were categorized into three early cancer cachexia phenotypes by changes in skeletal muscle and total adipose indices calculated using computed tomography images taken immediately before and within 3 months after the initiation of pembrolizumab: No Wasting (NW, 11 patients), Fat-Only Wasting (FW, 13), and Muscle and Fat Wasting (MFW, seven). Its association with objective response rate (ORR), progression-free survival (PFS), and overall survival (OS) were evaluated. RESULTS The median follow-up period was 5.7 months. The median number of cycles of pembrolizumab was five. The ORR in NW/FW/MFW was 86%/38%/0%, respectively (p = 0.001). The PFS and OS rates were the best in NW, followed in order by FW and MFW (PFS, 69%/45%/0% at 12 months, p = 0.008; OS, 100%/65%/0% at 12 months, p < 0.001). In multivariate analysis including posttherapeutic cachexia-associated parameters, cancer cachexia phenotype (MFW vs. FW/NW) was an independent predictor of poor OS (hazard ratio 8.59, p < 0.001) along with an increase in neutrophil-lymphocyte ratio (p = 0.028). CONCLUSION Early cancer cachexia phenotypes were significantly associated with the survival of aUC patients treated with pembrolizumab. In contrast to the very early progression and poor prognosis in the MFW group, long-term survival can be expected in the NW/FW groups.

Abstract
OBJECTIVE Indocyanine green (ICG) fluorescent lymphography might be useful for assessing patients undergoing lymphatic surgery for secondary lymphedema. The present clinical trial aimed to confirm whether ICG fluorescent lymphography would be useful in evaluating lymphedema, identifying lymphatic vessels suitable for anastomosis, and confirming patency of lymphaticovenular anastomosis in patients with secondary lymphedema. METHODS The present phase III, multicenter, single-arm, open-label, clinical trial (HAMAMATSU-ICG study) investigated the accuracy of lymphedema diagnosis via ICG fluorescent lymphography compared with lymphoscintigraphy, rate of identification of lymphatic vessels at the incision site, and efficacy for confirming patency of lymphaticovenular anastomosis. The external diameter of the identified lymphatic vessels and the distance from the skin surface to the lymphatic vessels using preoperative ICG fluorescent lymphography were measured intraoperatively under surgical microscopy. RESULTS When the clinical decision for surgery at each research site was made, the standard diagnosis of lymphedema was considered correct. For the 26 upper extremities, a central judgment committee who was unaware of the clinical presentation confirmed the imaging diagnosis was accurate for 100.0% of cases, whether the assessments had been performed via lymphoscintigraphy or ICG lymphography. In contrast, for the 88 lower extremities, the accuracy of the diagnosis compared with the diagnosis by the central judgment committee was 70.5% and 88.2% for lymphoscintigraphy and ICG lymphography, respectively. The external diameter of the identified lymphatic vessels was significantly greater in the lower extremities than in the upper extremities (0.54 ± 0.21 mm vs 0.42 ± 0.14 mm; P < .0001). Also, the distance from the skin surface to the lymphatic vessels was significantly longer in the lower extremities than in the upper extremities (5.8 ± 3.5 mm vs 4.4 ± 2.6 mm; P = .01). For 263 skin incisions, with the site placement determined using ICG fluorescent lymphography, the rate of identification of lymphatics vessels suitable for anastomosis was 97.7% (95% confidence interval, 95.1%-99.2%). A total of 267 lymphaticovenular anastomoses were performed. ICG fluorescent lymphography was judged as "useful" for confirming patency after the anastomosis in 95.1% of the cases. CONCLUSIONS ICG fluorescent lymphography could be useful for improving the treatment of patients with secondary lymphedema from the outpatient setting to surgery.

Abstract
OBJECTIVES To evaluate the trends and safety of robot-assisted partial nephrectomy during the initial 2-year period after government approval for this type of procedure in April 2016. METHODS This nationwide retrospective study included 3722 received robot-assisted partial nephrectomy cases carried out from April 2016 to March 2018 in 124 participating institutions. The institutions were divided into lower- and higher-volume institutions according to the median of 19 robot-assisted partial nephrectomy cases during the study period. Surgical outcomes between 616 cases from lower-volume institutions and 3106 cases from higher-volume institutions were compared using propensity score matching. RESULTS During the study period, both the number of robot-assisted partial nephrectomy surgeries and the number of institutions in which the surgery was carried out steadily increased. Overall, the median anesthesia time was 217 min, the median postoperative length of stay was 9 days, and the proportion of blood transfusions, complications and readmissions were 0.8%, 5.1% and 1.0%, respectively. There were no significant differences in anesthesia time, incidence of blood transfusions, and complication rates between the lower-volume and higher-volume institutions. However, a slightly, but significantly, longer postoperative length of stay and a lower incidence of readmission were observed in lower-volume institutions both before and after propensity score matching. CONCLUSIONS Robot-assisted partial nephrectomy has become widespread during the initial 2-year period after government approval with an acceptable safety profile, regardless of the institutional caseloads. This technique has become a standard of care for stage 1 renal cancer patients in Japan.

Abstract
OBJECTIVES Locally advanced renal cell carcinoma is considered clinically aggressive, despite heterogeneity in survival outcomes. We investigated the clinical relevance and pathological implications of infiltrative tumor interface with normal renal parenchyma on preoperative imaging in locally advanced renal cell carcinoma. METHODS A total of 77 patients with locally advanced renal cell carcinoma (≥pT3a Nany M0) who underwent radical or partial nephrectomy (2008-2018) were analyzed. Preoperative dynamic computed tomography images were reviewed to assess radiological infiltrative features. A radiological infiltrative feature was defined as an ill-defined tumor interface with normal renal parenchyma. The tumor interfaces were analyzed histologically and compared with radiological findings. RESULTS The median tumor size was 6.4 cm. Lymphadenopathy was observed in four patients (5.2%). Clear cell renal cell carcinoma was diagnosed in 66 patients (86%) and Fuhrman grade was 3-4 in 38 patients (49%). A total of 30 patients (39%) showed radiological infiltrative features, which were significantly associated with larger tumor size and higher clinical T stage. The specificity and sensitivity of radiological infiltrative features in predicting pathological renal parenchymal infiltration were 90 and 64%, respectively. During a median follow-up period of 3.8 years, 27 patients (35%) developed cancer recurrences, and six patients (7.8%) died of renal cell carcinoma. Multivariable analysis showed that the presence of radiological infiltrative features was an independent risk factor for cancer recurrence. Cancer recurrence and cancer-specific mortality were significantly stratified by the presence or absence of radiological infiltrative features (P < 0.001 and P = 0.02, respectively). CONCLUSIONS Locally advanced renal cell carcinoma can show radiological infiltrative features preoperatively, which are significantly associated with unfavorable prognosis. Radiological infiltrative features on preoperative imaging correspond with a high specificity to pathological renal parenchymal infiltration.
