    This study aimed to evaluate the outcomes of patients with advanced renal cell carcinoma (aRCC) who were histologically diagnosed with non-clear cell carcinoma (nccRCC) and received combination immunotherapy. Oncological outcomes were compared between patients with non-clear cell RCC (nccRCC group) and those with clear cell RCC (cc-RCC group) who received either immune checkpoint inhibitor (ICI) + ICI combination therapy (ICI + ICI) or ICI + tyrosine kinase inhibitor (TKI) therapy (ICI + TKI). This retrospective study analyzed patients with aRCC who received combination immunotherapy as first-line treatment at 12 institutions between August 2018 and November 2023. The primary endpoint was the comparison of overall survival (OS) between the nccRCC and cc-RCC groups. The secondary endpoints included progression-free survival (PFS) and objective response rate (ORR) in both groups. The median follow–up periods for the nccRCC and cc-RCC groups were 17.7 and 20.4 months, respectively. The median OS was significantly shorter in the nccRCC group compared to the cc-RCC group (27.8 months vs. 62.8 months; p < 0.001). The ORRs in the nccRCC and cc-RCC groups were 52.4% and 63.6%, respectively. Among patients treated with ICI + ICI, the median OS was significantly shorter in the nccRCC group compared to the cc-RCC group (23.5 months vs. 62.8 months; p < 0.001). In the current era of ICI treatment, patients with nccRCC exhibit poorer oncological outcomes than those with cc-RCC. Indications should be evaluated thoroughly before selecting ICI + ICI treatment combinations for these patients.

    Introduction: Tumor development in the ileal conduit is rare. Herein, we present a case of metastatic malignant melanoma occurring within the ileal conduit 17 years after radical cystectomy. Case Presentation: A 76-year-old Japanese man, with a history of bladder cancer treated with radical cystectomy and ileal conduit diversion, presented with gross hematuria. He had malignant melanoma diagnosed 10 years prior, with recurrent metastases managed through surgery and adjuvant therapy. During his recent admission, metastases to the subcutaneous tissue and retroperitoneum were noted. Contrast-enhanced computed tomography revealed bilateral hydronephrosis and a tumor in the ileal conduit. Endoscopic resection confirmed metastatic malignant melanoma. The patient's renal function stabilized postoperatively, and hematuria was controlled. A palliative care approach was adopted to treat the melanoma. Conclusion: This rare case of metastatic malignant melanoma within an ileal conduit highlights the importance of histopathological examinations in patients with overlapping malignancies. Trial Registration: 2016-0474.

    A 65-year-old man, a post living donor kidney transplant patient, was admitted to the intensive care unit (ICU) with a severe bacterial infection. He also tested positive for coronavirus disease and had a cough. On admission, heparin was administered for atrial fibrillation. On the third day of hospitalization, his general condition had recovered, and he was discharged from the ICU to the general ward. On the fourth day of hospitalization, he experienced abdominal pain, and a hard mass was palpated in the left lower abdomen. On the fifth day of hospitalization, contrast-enhanced computed tomography showed an extensive rectus sheath hematoma (RSH) extending from the left lower abdominal wall to the left side of the bladder, with extravasation from a small branch of the left inferior epigastric artery. Heparin was discontinued, and transcatheter arterial embolization was performed to control the bleeding. RSH is a rare disease, and cases of extensive hematoma in post-kidney transplant patients occur even less frequently. Patients taking anticoagulants and those with chronic kidney disease are at high risk for RSH, so physicians should be cognizant of this disease when these patients develop abdominal pain.

    A 50-year-old man who had undergone a living-donor kidney transplant 12 years prior for chronic renal failure due to autosomal dominant polycystic kidney disease contracted coronavirus disease 19 (COVID-19). He had a positive antigen test, mild symptoms, sore throat, and fever of 37.9 ℃. The patient was treated with molnupiravir for 5 days, and the symptoms disappeared 5 days after onset. However, 10 days after onset, he developed a fever of approximately 37 ℃ and a non-productive cough; 27 days after onset, the patient was hospitalized for anorexia and a worsening respiratory condition. The severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) antigen test results on admission were negative, and no antiviral medications were administered against SARS-CoV-2. Computed tomography revealed extensive ground-glass opacities in both lung fields. The patient was treated with steroid pulse therapy, ceftriaxone, atovaquone, azithromycin, and respiratory management using a high-flow nasal cannula. The combined therapies were successful, and the patient was managed with a nasal oxygen cannula after 3 days. Oxygen administration was discontinued after 6 days of hospitalization, and the patient was discharged after 14 days. Based on the laboratory findings, bacterial, interstitial, and Pneumocystis pneumonia were unlikely. The success of the steroid pulse therapy suggested that respiratory failure was caused by pneumonia due to the immune response after COVID-19 infection.

    Introduction: Immunosuppressed patients exhibit low antibody acquisition rates following severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) vaccination. Kidney transplant recipients previously exhibited low antibody acquisition rates after two vaccine doses, which increased after the third dose. We evaluated antibody titers of Japanese post-kidney transplant patients after the fourth and fifth vaccinations. Methods: Antibody titers for SARS-CoV-2 spike protein were measured between 3 weeks and 3 months after the fourth or fifth vaccination. Results: Increased antibody acquisition rates were observed after the fourth (75.0% antibody-positive) and fifth (81.5% antibody-positive) vaccinations. The antibody-acquired group after the fourth vaccination exhibited a higher body mass index and estimated glomerular filtration rate (eGFR) than the non-acquired group. A higher eGFR was associated with antibody acquisition after the fifth vaccination. Conclusion: In Japanese post-kidney transplant patients, the antibody acquisition rate increased with each vaccine additional dose. Additional vaccinations are recommended to protect against SARS-CoV-2 infection.

    Androgen receptor signaling inhibitors combined with androgen deprivation therapy have become the standard of care for metastatic castration-sensitive prostate cancer (mCSPC), regardless of tumor volume or risk. However, survival of approximately one-third of these patients has not improved, necessitating further treatment escalation. On the other hand, for patients with oligometastatic mCSPC, there is an emerging role for local radiation therapy. Although data remain scarce, it is expected that treatment of both primary tumor as well as metastasis-directed therapy may improve survival outcomes. In these patients, systemic therapy may be de-escalated to intermittent therapy. However, precise risk stratification is necessary for risk-based treatment escalation or de-escalation. In addition to risk stratification based on clinical parameters, research has been conducted to incorporate genomic and/or transcriptomic data into risk stratification. In future, an integrated risk model is expected to precisely stratify patients and guide treatment strategies. Here, we first review the transition of the standard treatment for mCSPC over the last decade and further discuss the newest concept of escalating or de-escalating treatment using a multi-modal approach based on the currently available literature.

    Introduction: Simple plasma exchange (PE) with fresh-frozen plasma replacement allows antibody removal for ABO-incompatible living donor kidney transplantation, but is associated with a high incidence of allergic reactions. We developed, implemented, and evaluated a protocol for safe preoperative PE. Methods: The protocol comprised pretreatment (125 mg methylprednisolone infusion, 400 mg acetaminophen and 30 mg diphenhydramine orally) with a replacement fluid rate < 20 mL/min. Allergic reaction incidence was investigated in controls who underwent ABO-incompatible living donor kidney transplantation between 2016 and March 2020 (group C) and patients who underwent the protocol and procedure between April 2020 and February 2023 (group N). Results: Ten (group C) and 19 (group N) patients performed 11 and 30 sessions of PE, respectively. Allergic reactions occurred in 81.8% and 36.7% (p = 0.014), respectively, with an odds ratio of the protocol was 0.056 (95% CI 0.0059–0.5380, P = 0.013). Conclusion: Our protocol resulted in a significantly lower incidence of allergic reactions.

    Intraductal carcinoma of the prostate, a unique histopathologic entity that is often observed (especially in advanced prostate cancer), is characterized by the proliferation of malignant cells within normal acini or ducts surrounded by a basement membrane. Intraductal carcinoma of the prostate is almost invariably associated with an adjacent high-grade carcinoma and is occasionally observed as an isolated subtype. Intraductal carcinoma of the prostate has been demonstrated to be an independent poor prognostic factor for all stages of cancer, whether localized, de novo metastatic, or castration-resistant. It also has a characteristic genetic profile, including high genomic instability. Recognizing and differentiating it from other pathologies is therefore important in patient management, and morphological diagnostic criteria for intraductal carcinoma of the prostate have been established. This review summarizes and outlines the clinical and pathological features, differential diagnosis, molecular aspects, and management of intraductal carcinoma of the prostate, as described in previous studies. We also present a discussion and future perspectives regarding intraductal carcinoma of the prostate.

    Rationale: The purpose of this case report is to describe a case of successful early rehabilitation intervention for simultaneous liver and kidney transplantation (SLKT). Patient concerns: A 51-year-old Japanese man was diagnosed with Caroli disease 27 years ago. Hemodialysis was introduced due to end-stage renal disease 17 years ago. Diagnoses: After successful SLKT, the patient was extubated on postoperative day (POD) 1, liberated from dialysis on POD 4, and discharged from the intensive care unit on POD 9. Interventions: Supervised rehabilitation was started on POD 2, and the patient was able to walk 100 m on POD 9. Electrical muscle stimulation therapy was started to improve muscle weakness in both legs on POD 16, and aerobic exercise using a cycle-ergometer was started on POD 24. Outcomes: The 6-minute walking distance improved from 324 m on POD 14 to 501 m on POD 28. The patient could walk 4000 to 5000 steps per day at hospital discharge, and was discharged home on POD 32. There were no adverse events, including worsening hepatic or renal function, during the rehabilitation period. One month after discharge, the patient was able to perform 30 to 40 minutes of aerobic exercise every day, and returned to work 5 months after discharge. Lessons: This case shows that early rehabilitation intervention immediately after SLKT safely and rapidly improved physical performance without adverse events. The results in the present case suggest that regular physical assessment and appropriate interventions with a variety of exercise modalities can contribute to improved physical performance in SLKT patients.
