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

OBJECTIVE: To investigate the prevalence of frailty and its effects on cancer-related fatigue and quality of life among patients with prostate cancer. METHODS: In this cross-sectional study, questionnaires were administered to 254 outpatients who visited the Department of Urology at Kagawa University Hospital for prostate cancer; finally, 108 outpatients were analyzed. Frailty, cancer-related fatigue and quality of life were assessed using the G8 screening tool, Japanese version of the Brief Fatigue Inventory and Japanese version of the Short Form 8 Health Survey, respectively. We defined frailty based on a score ≤14 points and divided the patients into frailty and no-frailty groups. We also compared the severity of cancer-related fatigue and quality of life between groups. RESULTS: The prevalence of frailty among 108 outpatients was 63%. Older age correlated with frailty severity (P = 0.0007) but not cancer-related fatigue severity (P = 0.2391). The proportion of patients on treatment or with metastasis was not significantly different between groups. The frailty group had higher cancer-related fatigue severity (P = 0.004) and decreased levels of general activity, mood, walking ability, normal work and enjoyment of life, especially on the Brief Fatigue Inventory subscale. The frailty group had lower physical and mental quality of life than the no-frailty group or general population. CONCLUSIONS: The frailty rate for these patients increased with age, exceeding 60% regardless of the treatment status, and was associated with worsened cancer-related fatigue severity and reduced quality of life. Our study highlights the importance of assessing frailty when selecting treatment, especially in older patients.

BACKGROUND: Japanese men receiving apalutamide often experience skin-adverse events (AEs), possibly requiring treatment interruption or dose reduction. However, concerns have arisen regarding the impact of these adjustments on the efficacy of apalutamide. Our study evaluated the efficacy, safety, and persistence of apalutamide in men with metastatic castration-sensitive prostate cancer (mCSPC). METHODS: We retrospectively reviewed the medical records of 108 men with mCSPC from 14 Japanese institutions. The primary outcomes were the efficacy of apalutamide: prostate-specific antigen (PSA) response (50%, 90% and < 0.2 decline) and progression to castration-resistant prostate cancer (CRPC). The secondary outcomes were the skin-AE and compliance of apalutamide. RESULTS: PSA50%, PSA90% and PSA < 0.2 declines were observed in 89.8, 84.3 and 65.7%, and the median time to CRPC progression was not reached. PSA < 0.2 decline and an initial full dose of apalutamide were significantly associated with a longer time to CRPC. The most common AE was skin-AE (50.9%), and there was no association between the occurrence of skin-AE and the time to CRPC (P = 0.72). The median apalutamide persistence was 29 months, which was longer in the initial full dose recipients than in the reduced dose recipients. The dosage is reduced in about 60% of patients within the first year of treatment in the initial full dose recipients. CONCLUSIONS: Our findings indicate the effectiveness of apalutamide in Japanese men with mCSPC, despite a substantial portion requiring dose reduction within a year among the initial full dose recipients.

BACKGROUND: Enfortumab vedotin is a novel antibody-drug conjugate used as a third-line therapy for the treatment of urothelial cancer. We aimed to elucidate the effect of enfortumab vedotin-related peripheral neuropathy on its efficacy and whether enfortumab vedotin-induced early electrophysiological changes could be associated with peripheral neuropathy onset. METHODS: Our prospective multicenter cohort study enrolled 34 patients with prior platinum-containing chemotherapy and programmed cell death protein 1/ligand 1 inhibitor-resistant advanced urothelial carcinoma and received enfortumab vedotin. The best overall response, progression-free survival, overall survival, and safety were assessed. Nerve conduction studies were also performed in 11 patients. RESULTS: The confirmed overall response rate and disease control rate were 52.9% and 73.5%, respectively. The median overall progression-free survival and overall survival were 6.9 and 13.5 months, respectively, during a median follow-up of 8.6 months. The patients with disease control had significantly longer treatment continuation and overall survival than did those with uncontrolled disease. Peripheral neuropathy occurred in 12.5% of the patients. The overall response and disease control rates were 83.3% and 100%, respectively: higher than those in patients without peripheral neuropathy (p = 0.028 and p = 0.029, respectively). Nerve conduction studies indicated that enfortumab vedotin reduced nerve conduction velocity more markedly in sensory nerves than in motor nerves and the lower limbs than in the upper limbs, with the sural nerve being the most affected in the patients who developed peripheral neuropathy (p = 0.011). CONCLUSION: Our results indicated the importance of focusing on enfortumab vedotin-induced neuropathy of the sural nerve to maximize efficacy and improve safety.

OBJECTIVES: To assess whether the coronavirus disease (COVID-19) pandemic affected the outcomes of robot-assisted radical prostatectomy (RARP) and urologists' treatment behaviors. METHODS: We retrospectively examined the medical records of 208 patients who had undergone RARP between August 2017 and December 2022. We compared the rate of preoperative androgen deprivation therapy (ADT), waiting period for RARP, patients' baseline characteristics and quality of life (QOL), proportion of adverse pathology on the RARP specimen, rate of Gleason grade group upgrading from biopsy to the RARP specimen, and prostate-specific antigen (PSA) recurrence-free survival between the pre-pandemic and pandemic groups. RESULTS: The rate of preoperative ADT was significantly higher during than before the COVID-19 pandemic (13.7% vs. 1.9%; p = 0.002). The baseline physical and mental QOL scores did not differ significantly between the groups. The proportion of D'Amico low-risk patients was significantly lower (13.6% vs. 1.2%, p = 0.005) and waiting period for RARP was significantly shorter (median 3.5 months vs. 4.0 months, p = 0.016) in the pandemic group than in the pre-pandemic group. There was no significant difference in the proportion of adverse pathology between the groups (p = 0.104); however, the upgrading rate was significantly higher in the pre-pandemic group (p = 0.002). There was no significant difference in PSA recurrence-free survival between the groups (log-rank, p = 0.752). CONCLUSIONS: The COVID-19 pandemic did not adversely affect the oncologic outcomes of RARP and QOL before RARP. However, it caused urologists to increase the use of preoperative ADT and to reserve RARP for higher-risk cases.

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

OBJECTIVE: this study aimed to evaluate the active surveillance continuation period, treatment intervention rate and health-related quality of life in younger patients. METHODS: we prospectively conducted a health-related quality of life survey of patients enrolled in the Prostate Cancer Research International: Active Surveillance-JAPAN study at Kagawa University between January 2010 and December 2020. Health-related quality of life was assessed by mail using a validated Japanese version of the Short-Form 8 Health Survey and Expanded Prostate Cancer Index at active surveillance enrolment and annually thereafter until discontinuation of active surveillance. We divided the patients into two groups, younger (aged <65 years) and older (aged ≥65 years), and compared the two groups. RESULTS: of the 84 patients, 22 were in the younger group. The active surveillance continuation period was shorter in the younger group than in the older group. The 3-year treatment intervention rate was higher in the younger group than in the older group. The majority of the reasons for definitive treatment were related to the protocol, which was similar in both groups (80 versus 76%). The sexual summary scores at active surveillance enrolment were higher in the younger group than in the older group. During active surveillance, the younger group and the older group showed no deterioration in all health-related quality of life scores compared with the scores at the enrolment of active surveillance. CONCLUSIONS: patient-reported health-related quality of life survey indicated that the health-related quality of life of younger Japanese patients was maintained over time during active surveillance, similar to that of older patients.

BACKGROUND: In men undergoing upfront active surveillance, predictors of adverse pathology in radical prostatectomy specimens, including intraductal carcinoma of the prostate and cribriform patterns, remain unknown. Therefore, we aimed to examine whether adverse pathology in radical prostatectomy specimens could be predicted using preoperative patient characteristics. METHODS: We re-reviewed available radical prostatectomy specimens from 1035 men prospectively enrolled in the PRIAS-JAPAN cohort between January 2010 and September 2020. We defined adverse pathology on radical prostatectomy specimens as Gleason grade group ≥3, pT stage ≥3, pN positivity or the presence of intraductal carcinoma of the prostate or cribriform patterns. We also examined the predictive factors associated with adverse pathology. RESULTS: All men analyzed had Gleason grade group 1 specimens at active surveillance enrolment. The incidence of adverse pathologies was 48.9% (with intraductal carcinoma of the prostate or cribriform patterns, 33.6%; without them, 15.3%). The addition of intraductal carcinoma of the prostate or cribriform patterns to the definition of adverse pathology increased the incidence by 10.9%. Patients showing adverse pathology with intraductal carcinoma of the prostate or cribriform patterns had lower biochemical recurrence-free survival (log-rank P = 0.0166). Increasing age at active surveillance enrolment and before radical prostatectomy was the only predictive factor for adverse pathology (odds ratio: 1.1, 95% confidence interval: 1.02-1.19, P = 0.0178; odds ratio: 1.12, 95% confidence interval: 1.02-1.22, P = 0.0126). CONCLUSIONS: Increasing age could be a predictive factor for adverse pathology. Our findings suggest that older men could potentially derive advantages from adhering to the examination schedule in active surveillance.

BACKGROUND: Among early stage prostate cancer patients, intraductal carcinoma of the prostate (IDC-P) and invasive cribriform are key prognostic factors; however, their presence and clinical significance following active surveillance (AS) are unknown. In men who opted for AS, we aimed to examine the presence and impact of IDC-P or cribriform, utilizing radical prostatectomy (RP) specimens. METHODS: We re-reviewed 137 RP specimens available in the PRIAS-JAPAN prospective cohort between January 2010 and September 2020. We assessed the presence of IDC-P or cribriform, and compared the patients' characteristics and prostate-specific antigen (PSA) recurrence-free survival after RP between groups with and without IDC-P or cribriform. In addition, we examined the predictive factors associated with IDC-P or cribriform. RESULTS: The percentage of patients with IDC-P or cribriform presence was 34.3% (47 patients). IDC-P or cribriform pattern was more abundant in the higher Gleason grade group in RP specimens (P < 0.001). The rates of PSA recurrence-free survival were significantly lower in the IDC-P or cribriform groups than in those without them (log rank P = 0.0211). There was no association between IDC-P or cribriform on RP with the Prostate Imaging-Reporting and Data System (PI-RADS) 4,5 score on magnetic resonance imaging (MRI) before RP even with adjustments for other covariates (OR, 1.43; 95% confidence interval [CI] 0.511-3.980, P = 0.497). CONCLUSIONS: IDC-P or cribriform comprised approximately one-third of all RP specimens in men who underwent RP following AS, confirming their prognostic significance.

OBJECTIVE: This study conducted a national questionnaire survey of Japanese urologists from a treatment perspective for older patients with prostate cancer. METHODS: A questionnaire was distributed to 922 teaching hospitals of the Japanese Urological Association. Questionnaire items included years of urologist experience, gender, workplace, treatment equipment owned, daily specialty practice area, urological cancer specialty, treatment reference items for older adults, upper age limit for radical treatment, medication, and two hypothetical cases of Gleason grade group 2 prostate cancer with or without oligometastasis. RESULTS: In total, 1732 questionnaires were analyzed, with responses evenly distributed across all age groups. Workplaces included general hospitals (49.4%), university hospitals (40.3%), and cancer centers (4.2%). Performance status was the most frequently mentioned treatment-related item, followed by comorbidities and cognitive function. In addition, geriatric assessment was used by only 13.3% of respondents. No upper age limit was found for total prostatectomy, brachytherapy, and external beam radiation. Anti-androgens, androgen receptor-axis-targeted agents, chemotherapy, poly ADP ribose polymerase inhibitors, and immune-checkpoint inhibitors were selected by 6.8%, 35.6%, 47.3%, 89%, 62.8%, 24.7%, 41.9%, and 41.7% of the respondents, respectively. Response rates for administration of hormone therapy for hypothetical cases of Gleason grade group 2 prostate cancer with or without oligometastases were 96.8% and 61.2%, respectively. CONCLUSIONS: Less than 15% of urologists used geriatric assessments. Several responded that they would set age limits for highly invasive radical and systemic therapies.

OBJECTIVE: To conduct a national questionnaire survey of Japanese urologists on active surveillance (AS) for low- and intermediate-risk prostate cancer (PCa). METHODS: A questionnaire was sent to 922 Japanese Urological Association Teaching Base Hospitals. The items included were years of experience as a urologist, sex, workplace, treatment equipment owned, specialty area of daily practice, specialty area of urological cancer, and six hypothetical cases of AS. The cases were categorized by the following Gleason scores: 3 + 3 low risk of PCa, 3 + 4 intermediate risk, and 4 + 3 intermediate risk, with or without comorbidities for each case. Comorbidities were defined as cardiovascular diseases or illnesses warranting anticoagulant therapy. RESULTS: Altogether, 1962 questionnaires were analyzed. Responses were almost equally distributed among all age groups. Workplaces included general hospitals (49.4%), university hospitals (40.3%), and cancer centers (4.2%). Percentages of proposed AS for low risk/no comorbidity, low risk/with comorbidity, intermediate-risk 3 + 4/no comorbidity, intermediate risk 3 + 4/with comorbidity, intermediate risk 4 + 3/no comorbidity, and intermediate risk 4 + 3/with comorbidity were 90.5%, 90%, 39.5%, 48.7%, 15%, and 22%, respectively. Analysis of the correspondents' backgrounds showed that the more the urologists' years of experience, the less they were to advise AS of low-risk patients. In the presence of comorbidities, urologists across all age groups tended to propose AS, even in the same Gleason grade group. Cancer center urologists recommended AS more often than their counterparts at general and university hospitals. CONCLUSIONS: Approximately 40% of urologists proposed AS for intermediate-risk cases, confirming that AS for intermediate-risk patients is being considered in Japan.

BACKGROUND: This study aimed to evaluate the pathological findings and oncological outcomes of deferred radical prostatectomy in patients who initially elected for active surveillance in a Japanese cohort. METHODS: We retrospectively analyzed data collected from a multi-institutional prospective observational cohort of the Prostate Cancer Research International: Active Surveillance-JAPAN study between January 2010 and September 2020. Triggers for radical prostatectomy were disease progression based on pathological findings of repeat biopsy and patients' request. The primary end point was evaluation of prostate-specific antigen recurrence-free survival. Secondary end points were overall survival and comparison of pathological and oncological outcomes between patients stratified into immediate or late radical prostatectomy group by time to radical prostatectomy. RESULTS: Overall, 162 patients (15.7%) with prostate cancer underwent initial active surveillance followed by radical prostatectomy. The median time to radical prostatectomy was 18 months (interquartile range 14-43.3), and the median postoperative follow-up was 32 months (interquartile range 14-57.5). Prostate-specific antigen recurrence was observed in eight patients (4.9%). The 3-year prostate-specific antigen recurrence-free survival rate was 96.9%. The 5-year overall survival rate was 100%; however, one patient died of another cause. There were no significant differences in pathological findings between immediate and late radical prostatectomy groups. No significant difference in prostate-specific antigen recurrence-free survival was found between the two groups (log-rank p = 0.34). CONCLUSIONS: Radical prostatectomy after active surveillance, as an initial treatment option, does not lead to loss of curative chances in Japanese patients with early-stage prostate cancer in the short follow-up period.

Testicular epidermoid cysts are relatively rare, accounting for about 1% of all testicular tumors, and are often treated by high orchiectomy. We describe here the case of a testicular epidermoid cyst treated by testicle-sparing surgery due to a preoperative diagnosis. A 23-year-old man complained of a painless mass in the right scrotum. Physical examination revealed a firm little fingertip-sized smooth-surfaced mass in the right testis. Ultrasonography showed a hypoechoic lesion with an echogenic rim in the right testis. A T2-weighted magnetic resonance image showed a well-demarcated mass with a low signal outline. On the basis of a preoperative diagnosis of epidermoid cyst, intraoperative testicular frozen section was performed, and the mass was resected surgically while preserving the testis.

A 74-year-old man presented with further treatment for muscle invasive small cell carcinoma of the bladder. After three courses of neoadjuvant chemotherapy with cisplatine + etoposide (EP), total cystectomy was performed. The pathological findings revealed small cell carcinoma of the bladder (ypT2N0M0). Eleven months after the operation, thoracoabdominal computed tomography (CT) showed right pelvic lymph node metastasis. He underwent 9 courses of EP chemotherapy, and everolimus, finally, Amrubicin was administered. Amrubicin might be useful for small cell carcinoma of the bladder.

BACKGROUND: Chronic inflammation is thought to be a major causative factor for the development of benign prostatic hyperplasia (BPH) and lower urinary tract symptoms (LUTS). Tadalafil, a phosphodiesterase type 5 inhibitor (PDE5-I), which has been used for the treatment of BPH-LUTS in daily practice, is known to act at several urinary organs. In this study, focused on the prostate, we examined the effect of tadalafil on the pathological changes and inflammatory factors in a rat nonbacterial prostatitis (NBP) model. METHODS: Forty ten-month-old male Wistar rats were divided into nonbacterial prostatitis (NBP), NBP with tadalafil treatment (NBP-tadalafil), control, and control treated with tadalafil (control-tadalafil) groups (n = 10 per group). The NBP and NBP-tadalafil groups were castrated and then received daily subcutaneous 17ß-estradiol for 30 days. The control-tadalafil and NBP-tadalafil groups were administered daily oral tadalafil for 30 days. All rats were then sacrificed and pathological changes and inflammatory factors were assessed in the prostatic tissues. RESULTS: In the NBP group, the stroma-to-epithelium (S/E) ratio in the ventral prostate was significantly higher than in the control group (P < 0.001). In the NBP-tadalafil group, the S/E ratio was significantly lower than in the NBP group (P < 0.001). The macrophage levels and the extent of T-cell infiltration in the NBP-tadalafil group were significantly lower than in the NBP group (P < 0.005; P < 0.001, respectively). Compared with the NBP group, tissue concentrations of inflammatory cytokines, such as tumor necrosis factor-α, interleukin-8, and interleukin-1ß, were significantly downregulated in the NBP-tadalafil group (P < 0.01; P < 0.05; P < 0.005, respectively). CONCLUSIONS: Tadalafil suppressed stromal predominance and showed anti-inflammatory effects in a rat NBP model in association with downregulation of inflammatory cytokines.

Neutrophil-to-lymphocyte ratio (NLR), a simple marker of systemic inflammatory response, has clinical and prognostic value in patients with cancer. We evaluated the role of NLR prior to biopsy in patients suspected of having cancer prostate cancer. In this retrospective study, we reviewed the records of 204 patients who underwent prostate biopsy in Mizushima Kyodo Hospital between August 2002 and June 2015 and collected the following data : age, C-reactive protein (CRP), prostate volume (PV), clinical cancer staging, prostate-specific antigen (PSA) prior to biopsy , Gleason score (GS), NLR. NLR was calculated by prebiopsy neutrophil and lymphocyte counts. We divided the 83 of 204 patients found to have prostate cancer (PCa) into two or three groups by the results of biopsy, PSA, clinical cancer staging, GS, and D'Amico risk classification. Mann-Whitney U-test and Kruskal-Wallis H-test were used to compare NLR in each group. Significant differences were recognized in NLR between the groups : PSAâ§10 ng/ml VS ï¼ 10 ng/ml in all patients and in patients with cancer, cT2b⧠VS cT2câ¦, GS 6 VS GS 7 VS GS 8⦠in patients with cancer and low risk VS intermediate risk VS high risk in patients with cancer without metastasis. Also we investigated the correlated factor with NLR in patients with cancer without metastasis. On multiple regression analysis including age, CRP, PV, PSA, clinical tumor stage and GS, PSA and GS had a significant association with NLR.

Introduction: There have been reports of surgery for residual ureteral tumors, most of them involved open surgeries. Herein, we report a case of retroperitoneal scopic left ureteral resection and partial cystectomy, performed by placing a fluorescent ureteral catheter in the residual ureter. Case presentation: A 79-year-old man was admitted to our hospital with a chief complaint of gross hematuria. He had undergone transperitoneal left radical nephrectomy due to angiomyolipoma 20 years ago. Computed tomography and Magnetic resonance imaging revealed a solid tumor in the left residual ureter. Retroperitoneal scopic residual ureterectomy has been performed. During the operation, a fluorescent ureteral catheter proved to be very helpful in detecting the ureter. Conclusion: A fluorescent ureteral catheter is considered to be a useful tool in laparoscopic surgery, especially in cases where identification of the ureter is expected to be difficult, such as the residual ureter in this case.
RESUMO
BACKGROUND: The efficacy of photodynamic diagnosis using 5-aminolevulinic acid during transurethral resection of bladder tumors has been demonstrated, albeit with limited information regarding its side effects. This study aimed to clarify the impact of oral 5-aminolevulinic acid on perioperative nausea and vomiting (NV) for the first time in a real-world clinical practice setting. METHODS: Patients who underwent transurethral surgery at Kagawa University between April 2017 and March 2020 were included. Perioperative NV and antiemetic use status were prospectively assessed and compared between the patients who received oral 5-aminolevulinic acid and those who did not. Additionally, univariate and multivariate analyses were performed for predicting postoperative nausea and vomiting. RESULTS: Of 214 patients, 74 (34.6%) received oral 5-aminolevulinic acid preoperatively. The proportions of preoperative NV and antiemetic use in the patients who received 5-aminolevulinic acid were 9.5% and 4.1%, respectively, and higher than in those who did not (0% and 0%; P < 0.01 and P = 0.04, respectively). Postoperative NV (25.7%) and antiemetics use (8.0%) ratios in the patients who received 5-aminolevulinic acid were significantly different from those in the non-users group (3.6% and 2.1%, P < 0.01 and P < 0.01, respectively). Although no differences in risk factors were found for postoperative NV between the two groups, multivariate analyses indicated 5-aminolevulinic acid use as an independent predictive factor for postoperative NV (odds ratio, 11.5; 95% confidence interval, 3.98-33.3; P < 0.01). CONCLUSIONS: Our study clearly showed that oral administration of 5-aminolevulinic acid was associated with perioperative NV even without risk factors, highlighting the need for addressing its application.

BACKGROUND: Immune checkpoint inhibitors are new immunotherapy drugs globally used for many malignancies, including renal cell carcinoma. Myocarditis as an immune-related adverse event is rare but highly fatal, suggesting that its frequency may be higher than reported. This paper describes a case of myocarditis that developed asymptomatically following ipilimumab and nivolumab combination therapy for renal cell carcinoma. CASE PRESENTATION: A 71-year-old Asian man who presented to hospital with fever, fatigue, and weight loss of approximately 10 kg within 2 months was diagnosed with Xp.11.2 translocation renal cell carcinoma. Computed tomography revealed multiple lung masses, mediastinal lymph node enlargement, and a level II tumor thrombus reaching the inferior vena cava (cT3bN0M1; International Metastatic Renal Cell Carcinoma Database Consortium, poor risk). Ipilimumab/nivolumab combination therapy was started as induction therapy. The patient experienced acute interstitial nephritis as an immune-related adverse event after treatment initiation; however, a good response to steroid therapy was observed. The antitumor effect of the immunotherapy was notable. Although he experienced pulmonary embolism, it seemed asymptomatic and harmless; thus, a second infusion was introduced. From the eighth day, he demonstrated rapidly worsening cardiogenic shock with asymptomatic electrocardiographic changes and drastic drop in cardiac biomarkers, and a diagnosis of myocarditis as an immune-related adverse event was made. Although immediate methylprednisolone mini-pulse therapy followed by tapered prednisolone prevented mortality, extensive myocardial fibrosis with marked ejection fraction decline persisted as a sequela. Consequently, follow-up without treatment was instituted; however, much of the tumor response initially observed was maintained over several months. CONCLUSION: Physicians treating patients with immune checkpoint inhibitors should be aware of their potentially life-threatening cardiotoxic effects. This study emphasized the importance of a high index of suspicion, prompt diagnosis, and early intervention in patients who present with cardiac abnormalities and possible myocarditis after receiving immunotherapy.
