RESUMO
OBJECTIVES: We assessed preoperative factors predicting the poor therapeutic efficacy of holmium laser enucleation of the prostate (HoLEP) in benign prostatic hyperplasia (BPH) patients. METHODS: The present study included 159 patients who underwent HoLEP between August 2015 and June 2021 at our institution. Overall therapeutic efficacy was divided into good and poor therapeutic efficacies according to changes in the international prostate symptom score (IPSS), IPSS quality of life (IPSS-QOL), and the maximum urinary flow rate. Patients were divided into good and poor therapeutic efficacy groups based on findings obtained 3 months after HoLEP, and comparative assessments were performed between the two groups. RESULTS: The therapeutic efficacy of HoLEP was poor in 53 (33.3%) out of 159 patients. Intravesical prostatic protrusion (IPP), IPSS, IPSS-QOL, post-void residual volume (PVR), and the presence of overactive bladder (OAB) were significantly higher in the poor therapeutic efficacy group than in the good therapeutic efficacy group. A multivariable analysis of several factors identified the preoperative presence of OAB and short IPP as independent risk factors for the poor therapeutic efficacy of HoLEP. When treatment efficacy was divided according to risk factors, poor therapeutic efficacy was observed in only 14% of patients with prolonged IPP and the absence of OAB. CONCLUSIONS: The therapeutic efficacy of HoLEP may be poor in patients with OAB and short IPP, resulting in the significant deterioration of lower urinary tract symptoms. Accordingly, it is important to consider the presence or absence of OAB and IPP measurements when selecting indications for HoLEP.

BACKGROUND: Anti-programmed cell death 1 antibodies (anti-PD-1 Abs) are widely used for advanced melanoma, but the efficacy of an anti-PD-1 Abs is limited in the Asian population. There remains an unmet need to improve the therapeutic effects of anti-PD-1 Abs treatment, particularly in melanoma patients who are refractory to anti-PD-1 Abs. The aim was to evaluate anti-PD-1 Abs treatment in combination with TM5614 (plasminogen activator inhibitor-1: PAI-1 inhibitor) in patients with unresectable melanoma. METHODS: The TM5614-MM study was a multicentre, open-label, single-arm, phase 2 clinical trial to evaluate the efficacy and safety of nivolumab in combination with TM5614 in patients with advanced, unresectable malignant melanoma recruited at 7 Japanese institutes between 13 September 2021 and 31 March 2023. Patients with metastatic or unresectable melanoma previously treated with anti-PD-1 Abs were enrolled. Nivolumab 480 mg was administered intravenously every 4 weeks for 8 weeks, while TM5614 was administered orally at a dose of 120 mg (0-4 weeks) and 180 mg once daily (5-8 weeks). The primary endpoint was the overall response rate after 8 weeks of concomitant use of TM5614. RESULTS: Thirty nine patients were enrolled, and 34 patients in the anti-PD-1 Abs-refractory cohort. The overall response rate at 8 weeks was 25.9% (95% CI: 12.9-44.9%; P = .027) in 27 anti-PD-1-Abs refractory patients by investigator assessment in the protocol per set cohort. Seven patients discontinued treatment due to progressive disease or adverse events. Treatment-related grade 3 or higher adverse events occurred in 3 of 39 patients (7.7%) in the intention-to-treat cohort. CONCLUSIONS: TM5614 in combination with nivolumab is well-tolerated and effective in anti-PD-1 Abs-refractory, unresectable melanoma. TRIAL REGISTRATION: This trial was registered with Clinical Trial gov, jRCT2021210029.
RESUMO
BACKGROUND/AIM: Anthracycline-based chemotherapies including doxorubicin monotherapy are recommended in major guidelines for patients with advanced or metastatic retroperitoneal sarcoma (RPS); however, few studies have reported the outcomes of doxorubicin monotherapy for these patients. We herein investigated the oncological efficacy and safety of doxorubicin monotherapy for patients with advanced or metastatic RPS in real-world clinical practice. PATIENTS AND METHODS: Sixteen patients diagnosed with advanced or metastatic retroperitoneal sarcoma, receiving doxorubicin monotherapy as first-line treatment between February 2017 and March 2023 at our Institution were analyzed. Response rate, progression-free survival (PFS) periods, overall survival (OS) period, and adverse event (AE) profiles were retrospectively investigated. RESULTS: The median age of patients was 69.5 years. Best responses to doxorubicin were as follows: complete response, 0 patients (0.0%); partial response, 3 (18.8%); stable disease, 9 (56.3%); and progressive disease, 4 (25.0%). The objective response rate and disease control rate were 18.8 and 75.0%, respectively. During the observation period (median, 22 months, range=2-53 months), median PFS and OS periods were 8.0 and 24.0 months, respectively. The following AEs Grade ≥3 occurred: neutropenia in 14 patients (87.5%), febrile neutropenia in 5 (31.3%), leukopenia in 2 (12.5%), thrombocytopenia in 1 (6.3%), and heart failure in 1 (6.3%). Grade ≥3 nausea and vomiting did not occur and there was no treatment-related death. CONCLUSION: The oncological outcomes of doxorubicin monotherapy for RPS in real-world clinical practice were not inferior to those of the EORTC trial. The incidence of hematological AEs was higher; however, severe gastrointestinal AEs were prevented by prophylactic antiemetics and there were no treatment-related deaths. Collectively, doxorubicin monotherapy with appropriate prophylactic agents is a valid option for patients with advanced or metastatic RPS.

Onychomycosis, an infectious disease affecting the nails, can spread within oneself and to others, potentially leading to functional disabilities, therefore achieving a complete cure is necessary. Additionally, shared decision making (SDM) has been gaining attention in the treatment of various diseases in recent years. This study aimed to uncover the realities of patient-physician communication and perception in onychomycosis treatment, particularly in setting treatment goals and the SDM process for selecting therapeutic agents. We conducted a web-based survey of both patients and dermatologists to identify issues in the decision-making process for onychomycosis treatment. The survey revealed several communication challenges between patients and dermatologists regarding onychomycosis treatment. First, a notable percentage of dermatologists do not prioritize a complete cure for onychomycosis in their treatment goals. Second, the dermatologists' treatment explanations tended to emphasize risks, information necessary for appropriate decision-making was not adequately conveyed to patients, and SDM practice was insufficient (the mean scores of SDM-Q-9 and SDM-Q-Doc were 49.0 and 70.9, respectively). Third, dermatologists overestimated the reluctance of older patients to take oral medications. Dermatologists should recognize their patients' expectations for a complete cure for onychomycosis and choose a therapeutic agent that meets patients' needs. Furthermore, dermatologists should explain the benefits and risks of treatment options in a balanced manner, strive for improved patient-physician communication, and aim for a complete cure by administering suitable treatment.
RESUMO
BACKGROUND: This study evaluated the level of burden in pediatric and adolescent atopic dermatitis (AD) patients in Japan, the associated burden on caregivers/families, and whether this burden varied with age. METHODS: Data were drawn from the Adelphi Pediatric AD Disease Specific Programme (DSP)™, a cross-sectional survey of physicians and their patients conducted in Japan between July and December 2022. Physicians reported patient demographics, clinical characteristics, disease burden, and current/previous therapies. Patients and/or caregivers reported perceived disease severity and impact of AD, including the Children's Dermatology Life Quality Index (CDLQI) and Dermatitis Family Impact questionnaire (DFI). RESULTS: Overall, 55 physicians provided data for 537 AD patients aged ≤17. Mean (SD) overall scores for CDLQI, POEM, and DFI were 9.3 (6.3), 8.3 (6.8), and 11.7 (7.2), respectively. Age was associated with higher patient and/or caregiver-reported CDLQI scores, which increased by 0.543 points per year of age (P = 0.01). Patients with severe disease reported a more significant impact on quality of life factors compared with mild patients (P < 0.001). Age was associated with higher caregiver-reported burden, with DFI scores increasing by 0.325 per year (P = 0.01). Physician-reported impact on caregivers showed that age was significantly associated with increased burden on sleep, daily activities, work, and mood (P < 0.05), with disease severity associated with impact across all factors (P < 0.01). CONCLUSIONS: Both increasing age and disease severity were associated with the increased impact of AD on patients and their caregivers. Disease control/modification through appropriate therapeutic intervention at a younger age may relieve the burden of pediatric AD on patients and their families.
RESUMO
The pathogenesis of atopic dermatitis (AD) is understood to be crucially influenced by three main factors: dysregulation of the immune response, barrier dysfunction, and pruritus. In the lesional skin of AD, various innate immune cells, including Th2 cells, type 2 innate lymphoid cells (ILC2s), and basophils, produce Th2 cytokines [interleukin (IL)-4, IL-5, IL-13, IL-31]. Alarmins such as TSLP, IL-25, and IL-33 are also produced by epidermal keratinocytes, amplifying type 2 inflammation. In the chronic phase, not only Th2 cells but also Th22 and Th17 cells increase in number, leading to suppression of filaggrin expression by IL-4, IL-13, and IL-22, which further deteriorates the epidermal barrier function. Dupilumab, which targets IL-4 and IL-13, has shown efficacy in treating moderate to severe AD. Nemolizumab, targeting IL-31RA, effectively reduces pruritus in AD patients. In addition, clinical trials with fezakinumab, targeting IL-22, have demonstrated promising results, particularly in severe AD cases. Conversely, in murine models of AD, several cytokines, initially regarded as promising therapeutic targets, have not demonstrated sufficient efficacy in clinical trials. IL-33 has been identified as a potent activator of immune cells, exacerbating AD in murine models and correlating with disease severity in human patients. However, treatments targeting IL-33 have not shown sufficient efficacy in clinical trials. Similarly, thymic stromal lymphopoietin (TSLP), integral to type 2 immune responses, induces dermatitis in animal models and is elevated in human AD, yet clinical treatments like tezepelumab exhibit limited efficacy. Therapies targeting IL-1α, IL-5, and IL-17 also failed to achieve sufficient efficacy in clinical trials. It has become clear that for treating AD, IL-4, IL-13, and IL-31 are relevant therapeutic targets during the acute phase, while IL-22 emerges as a target in more severe cases. This delineation underscores the necessity of considering distinct pathophysiological aspects and therapeutic targets in AD between mouse models and humans. Consequently, this review delineates the distinct roles of cytokines in the pathogenesis of AD, juxtaposing their significance in human AD from clinical trials against insights gleaned from AD mouse models. This approach will improve our understanding of interspecies variation and facilitate a deeper insight into the pathogenesis of AD in humans.
RESUMO
BACKGROUND/AIM: The therapeutic impact of combination treatment with an immune checkpoint inhibitor (ICI) and chemotherapeutic agent on patients with urothelial cancer (UC) remains controversial. Therefore, the present study investigated differences in the therapeutic effects of combination therapy with cisplatin plus anti-mouse programmed death (PD)-1 antibody according to the dose of cisplatin using the mouse bladder tumor model MBT2. MATERIALS AND METHODS: The effects of treatment with two different doses cisplatin and/or anti-mouse PD-1 antibody on tumor growth after the subcutaneous injection of MBT2 cells were compared. Infiltrating patterns of lymphocytes into tumors after treatment were assessed using immunohistochemical staining. RESULTS: MBT2 tumor volumes were significantly larger in mice receiving high-dose cisplatin alone than in those receiving low-dose cisplatin alone. Combination treatment with cisplatin plus anti-mouse PD-1 antibody exerted significantly stronger growth inhibitory effects on MBT2 tumors than treatment with either agent alone, irrespective of cisplatin doses; however, no significant differences were observed in MBT2 tumor volumes between mice receiving anti-mouse PD-1 antibody plus high-dose cisplatin and those receiving anti-mouse PD-1 antibody plus low-dose cisplatin. Furthermore, CD8+ to CD3+ and CD8+ to CD11b+ T-lymphocyte ratios in MBT2 tumors were both significantly higher in the low-dose cisplatin alone group than in the high-dose cisplatin alone group, whereas no significant differences were noted in either ratio between the two different combination treatment regimens. CONCLUSION: When combined with ICI, a lower dose of cisplatin may achieve favorable antitumor effects in UC patients by preventing lymphocyte exhaustion.

Introduction: A newly developed surgical robot system, hinotori, with various unique advantages has been in clinical use in Japan; however, there have not been any studies of robot-assisted radical nephrectomy and inferior vena cava tumor thrombectomy using hinotori. Case presentation: We describe two male patients aged 67 and 76 years old with right renal cell carcinoma and a level II and I inferior vena cava tumor thrombus, respectively, undergoing robot-assisted radical nephrectomy and inferior vena cava tumor thrombectomy using hinotori. Both operations were successfully completed with a purely robotic procedure without any major perioperative complications, resulting in the following findings: time using robotic system, 158 and 156 min; total operative time, 228 and 214 min; estimated blood loss, 535 and 200 mL, respectively. Conclusion: Based on our first experience, robot-assisted radical nephrectomy and inferior vena cava tumor thrombectomy using hinotori may be an effective treatment for renal cell carcinoma with inferior vena cava tumor thrombus ≤level II.
RESUMO
BACKGROUND/AIM: Although the adverse events (AEs) of drugs, such as sunitinib and axitinib, have been shown to predict treatment responses, evidence to support cabozantinib-induced AEs as predictors of responses to treatment for metastatic renal cell carcinoma (mRCC) is limited. Therefore, we herein investigated the relationship between AE profiles and progression-free survival (PFS) in patients receiving cabozantinib for previously treated mRCC. PATIENTS AND METHODS: The present study retrospectively analyzed 40 patients receiving cabozantinib for previously treated mRCC between July 2020 and August 2022. PFS was estimated using the Kaplan-Meier method and the impact of several parameters, including cabozantinib-induced AEs, on PFS was investigated by a Cox proportional regression analysis. RESULTS: The median observation period was 15 (2-29) months, during which time 31 patients (77.5%) progressed, with median PFS of 11 months. Thirty-nine patients (97.5%) developed at least one AE. Liver toxicity occurred in 16 patients (40.0%) and hand-foot syndrome, hypertension, and diarrhea in 14 each (17.5%). Only hypertension correlated with longer PFS. A multivariate analysis identified hypertension as an independent prognostic factor for PFS (p=0.049). CONCLUSION: These results suggest the potential of treatment-induced hypertension as a significant predictor of prolonged PFS in patients receiving cabozantinib for mRCC.

Onychomycosis can be treated with topical and oral medications. However, it is important to appropriately select these medications according to the type and severity of the disease and ensure treatment is continued for the recommended duration. In Japan, treatment options for onychomycosis have increased in recent years. Moreover, in 2019, the guidelines for dermatomycosis treatment were revised. In this study, we conducted a receipt survey to clarify the actual treatment status of onychomycosis cases as indicated by the continuation rates of prescribed treatment drugs, together with a web-based survey to ascertain the prescribing policy of dermatologists regarding drugs for onychomycosis treatment. In agreement with past surveys, this receipt survey showed that the prescription continuation rate for oral medications was higher than that for topical medications. The 1-year prescription continuation rate for topical onychomycosis medications was found to be low (<10%). The web-based survey showed that the percentage of physicians who prescribed oral medications as their first choice increased by approximately 10% for each disease type, compared with the results of the previous survey conducted around 7 years ago. However, the study also confirmed that topical drugs are still prescribed for some disease types for which oral drugs are better suited. To ensure complete cure without patient drop-out, oral drugs with a high probability of achieving complete cure and a high continuation rate should be prescribed for patients with onychomycosis.

Background: The hinotori surgical robot system is a promising robotic platform that has been recently introduced into routine clinical practice. The aim of this study was to report our initial experience of robot-assisted radical nephroureterectomy (RANU) using hinotori. Methods: This study included a total of eight patients with upper urinary tract tumor (UUTT) who underwent RANU using hinotori via the transperitoneal approach. In this series, nephrectomy was initially performed at the kidney direction stage followed by distal ureterectomy and bladder cuff excision at the bladder direction stage without repositioning of patient or port. Lymphadenectomy was performed at either stage. Results: Median age, body mass index, and tumor diameter were 76 years, 21.7 kg/m2, and 13 mm, respectively. Of eight patients, three were diagnosed with renal pelvic tumors and five with lower ureteral tumors. They underwent lymphadenectomy targeting the renal hilum plus para-aorta and the pelvis, respectively. All procedures in this series were completed without conversion to open surgery. Median operative time, time using the robotic system, estimated blood loss, and length of hospital stay were 230 minutes, 138 minutes, 23 mL, and 8 days, respectively. No major perioperative complication occurred. Pathological examinations of the tumors revealed seven urothelial carcinomas and one papilloma, the median number of resected lymph nodes was 13, and one patient was positive for both cancer margin and lymph node metastases. Conclusions: Despite being a small case series, this is the first study characterizing RANU using the hinotori surgical robot system. RANU was efficaciously and safely performed, resulting in the achievement of favorable perioperative findings.
