Abstract
Immune checkpoint inhibitors have been shown to prolong survival of patients with several types of cancer, and the finding was first established in melanoma. Previously, systemic therapy for advanced melanoma aimed only at tumor control and palliation of symptoms. However, in recent years, some patients who received systemic therapy have achieved a complete response and survived without continuous treatment for more than several years. This review discusses the long-term survival rates achieved with currently used systemic therapies and their future perspectives. Long-term survival is currently most likely to be achieved with the use of the standard-dose combination of nivolumab plus ipilimumab, however, this regimen is associated with a high frequency of serious or persistent immune-related adverse events. Several new anti-PD-1-based combination therapies with a better risk-benefit balance are currently under development. Although the acral and mucosal subtypes tend to be less responsive to immune checkpoint inhibitors, anti-PD-1-based combination therapy should continue to be investigated for these subtypes owing to its potential for better long-term survival. With the development of efficacious immunotherapy and targeted therapy, it is important to determine the optimal duration of systemic therapy to avoid unnecessary health and financial burdens as well as to improve efforts to support long-term cancer survivors. As the goal of systemic therapy shifts from tumor control to long-term survival, in future clinical trials, long-term clinical outcomes should be evaluated to assess the benefits of novel agents.

Abstract
Information about extramammary Paget's (EMPD) treatment is limited because of the rarity of the disease. The prognosis differs between in situ EMPD and invasive EMPD; therefore, therapy should be planned according to the disease stage. We collected data on 643 EMPD cases treated between 2015 and 2019 in Japan and assessed recent trends in EMPD treatment and prognosis based on the EMPD-oriented TNM staging. Among the 643 patients, 317 had stage 0 (49.3%), 185 had stage I (28.8%), 51 had stage II (7.9%), 18 had stage IIIA (2.8%), 48 had stage IIIB (7.5%) and 24 had stage IV (3.7%) disease. Each stage showed a distinct survival curve, with the exception of stages II and IIIA. Curative surgery was most common in patients with stage 0-III disease. Chemotherapy was the first-line therapy, mainly in patients with stage IIIB and IV disease, most commonly with docetaxel (DTX), followed by DTX + tegafur gimeracil oteracil potassium (TS-1) and TS-1. Patients with local disease exhibited a 4.4% recurrence rate. Univariate analysis revealed no prognostic differences according to age, sex or primary tumour site. SLNB was not related to disease-specific survival. In multivariate analysis, female sex significantly predicted local relapse in stage 0-I (HR 3.09; 95% CI, 1.13-8.43), and initial treatment with curative surgery was significantly protective in terms of disease-specific survival in stage II-IIIA (HR, 0.17; 95% CI, 0.04-0.71) and stage IIIB-IV (HR 0.16; 95% CI, 0.05-0.51). Further clinical studies are needed to improve the prognosis of patients with stage II-IV EMPD.

Abstract
BACKGROUND Cutaneous apocrine carcinoma (CAC) is a rare adnexal carcinoma. Limited data exists on the demographics and overall survival (OS) of patients with CAC; thus, there is no consensus on surgical management. This study aimed to examine demographic and survival data of patients with CAC to determine optimal surgical management. METHODS A single-center retrospective cohort study was conducted at the National Cancer Center Hospital in Tokyo between 2005 and 2022. Patients with a histologically-confirmed CAC diagnosis were identified and data on patient demographics, OS, and lymph node (LN) status were gathered. RESULTS Thirty-two patients were included (median age, 65.5 years; male-female ratio, 15:1). The most common involvement site was the axilla (87.5%). Of the nine patients in the clinical local stage, pathological LN metastases were found in five patients. Either pathological LN or distant metastases were present in 75% of the patients at initial diagnosis. The most common initial surgical treatments included wide local excision and complete LN dissection. Across cohorts, the median OS was 39 months. Patients with ≥ 4 LN metastases had reduced recurrence-free survival and OS compared to those with ≤ 3 LN metastases (p = 0.042, p = 0.041, respectively). The OS was not remarkably different between patients who did and did not receive postoperative radiation therapy. CONCLUSIONS Since CAC has a high rate of LN metastasis-and the number of LN metastases is a significant prognostic factor-LN evaluation should be considered for patients with CAC as initial treatment. Nonetheless, ≥ 4 LN metastases can be a poor prognostic factor for CAC.

Abstract
BACKGROUND Melanoma brain metastasis (MBM) has a poor prognosis, although recent treatments, including immune checkpoint inhibitors and targeted therapy, have improved the prognosis. However, these systemic therapies have been reported to be less efficient for Asian patients. We investigated the survival of Asian patients with MBM and the effectiveness of systemic therapies. METHODS We retrospectively reviewed the survival rates of patients diagnosed with MBM between January 2011 and December 2021 at the National Cancer Center Hospital in Tokyo, Japan. In addition, we identified factors associated with survival using Cox regression analysis. RESULTS A total of 135 patients were included. The median overall survival (OS) after an MBM diagnosis was 7.8 months (95% confidence interval [CI] 6.1-9.6). The 6-month and 1-year survival rates were 60.7% and 34.8%, respectively. We identified the prognostic factors of MBM, including non-acral primary location, low serum LDH levels, systemic therapy of single-agent immune checkpoint inhibitors (ICIs) or targeted therapies (TTs), and radiotherapy of stereotactic irradiation (STI). We found no significant difference in effectiveness between single-agent ICIs, the combination of Nivolumab and Ipilimumab (COMBI-ICI), and TTs (COMBI-ICI vs. single-agent ICI, hazard ratio 0.71, 95% confidence interval 0.27-1.88, p = 0.49; COMBI-ICI vs. TT: hazard ratio 0.46, 95% confidence interval 0.14-1.55, p = 0.21). CONCLUSIONS Systemic therapy and radiotherapy have improved the survival of MBM patients, but the survival of Asian patients remains poor. Our findings suggest that COMBI-ICIs are not significantly more effective than single-agent ICI or TT in treating MBM.

Abstract
BACKGROUND Sentinel lymph node biopsy (SLNB) underuse has been reported for skin cancers; however, actual performance rates have not been compared. The objective of this study was to investigate the SLNB performance rate in skin cancers covered by health insurance in Japan and compare it with that in breast cancer. METHODS This was a retrospective study of the SLNB performance rate in SLNB-eligible patients with breast or skin cancer from 2018 to 2019, utilizing a database linked to the Hospital-Based Cancer Registry and Diagnosis Procedure Combination survey. Demographic and tumor characteristics were analyzed using logistic regression. RESULTS A total of 71,652 patients were included in this study. SLNB was performed in 86.4% (57,904/67,036) of the patients with breast cancer, 44.7% (694/1552) with melanomas, 3.1% (89/2849) with squamous cell carcinomas (SCCs), and 13.5% (29/215) with Merkel cell carcinomas (MCCs). The performance rate of SLNB was significantly lower for skin cancers than for breast cancers (odds ratio [OR], 0.03; p < 0.001). In addition, the performance rates of SLNB were significantly lower for SCCs and MCCs than for melanomas (SCC: OR, 0.04; p < 0.001; MCC: OR, 0.19; p < 0.001). Factors associated with SLNB performance included age, sex, year of incidence, primary tumor site, T stage, and number of hospital beds. CONCLUSIONS SLNB is underutilized for skin cancer. Further investigation is required to explore the reasons for its underutilization so that it may be implemented more universally.

Abstract
INTRODUCTION The healing of recurrent and refractory skin ulcers requires a long time, during which there is risk of infection, and hospital admission is occasionally required for surgical or daily conservative treatment. Therefore, the development of promising treatments that promote faster, uneventful healing is a must. Composed of cryoprecipitate and thrombin, fibrin glue has a history of surgical use for preventing bleeding and spinal fluid leakage. Moreover, in-house cryoprecipitates contain higher concentrations of coagulation factors and cytokines that may enhance wound healing than commercially available products. However, the efficacy of completely autologous fibrin glue (AFG) in tissue repair has not yet been fully demonstrated. PATIENT CONCERNS This study aimed to evaluate the efficacy of AFG in the treatment of refractory skin ulcers in comparison with the conventional treatment. DIAGNOSIS Two patients with skin ulcer on their lower extremities due to trauma or scleroderma who showed resistance to conventional treatment were included in the study. Both study participants were diagnosed with refractory skin ulcer and were ineligible for autologous skin transplantation. INTERVENTIONS AFG was prepared following autologous blood donation using a Cryoseal® system. Subsequently, AFG was administered to 50% of the area of each ulcer and observed for 4 weeks in comparison with recombinant basic fibroblast growth factor with bucladesine sodium treatment that was administered to the rest of the ulcer. OUTCOMES The skin ulcer after trauma in participant 1 showed better improvement in the AFG-treated area. Although AFG did not show superiority regarding the ulcer area of a patient with scleroderma, it guarded the continuous exudation from the edge of the swollen skin surrounding the ulcer. CONCLUSION AFG showed effective and beneficial results for wound healing of refractory skin ulcer and prevented exudation without any severe adverse events.

Abstract
BACKGROUND Head and neck mucosal melanomas are rare malignancies. Although the prognosis is poor owing to the high incidence of distant metastases, locoregional control remains important. It is difficult to obtain results in a large cohort because of its rarity. This study aimed to elucidate the survival outcomes of patients with head and neck mucosal melanoma treated with surgery in Japan. METHODS Patients with head and neck mucosal melanoma who were surgically treated between 2007 and 2021 at the National Cancer Center Hospital were retrospectively analyzed. RESULTS A total of 47 patients were included in this study. The 5-year overall survival, disease-specific survival, locoregional control and relapse-free survival rates were 42%, 50%, 79% and 13%, respectively. The disease-specific survival of the oral mucosal melanoma group was significantly better than that of the sinonasal mucosal melanoma group (5-year disease-specific survival rate: 70% versus 37%, respectively; P = 0.04). Multivariate analyses revealed that sinonasal mucosal melanoma were independently significant adverse prognostic factor, for overall survival and disease-specific survival. Patients with oral mucosal melanoma patients had a higher incidence of lymph node metastasis than those with sinonasal mucosal melanoma patients (P < 0.0001). CONCLUSION This study demonstrated the survival outcomes of the largest cohort of patients with head and neck mucosal melanomas treated surgically at a single institution within the past 20 years in Japan. We found that survival outcomes and incidence of nodal metastases varied by site.

Abstract
BACKGROUND Anti-PD-1-based immunotherapy is considered a preferred first-line treatment for advanced BRAF V600-mutant melanoma. However, a recent international multi-center study suggested that the efficacy of immunotherapy is poorer in Asian patients in the non-acral cutaneous subtype. We hypothesized that the optimal first-line treatment for Asian patients may be different. METHODS We retrospectively collected data of Asian patients with advanced BRAF V600-mutant melanoma treated with first-line BRAF/MEK inhibitors (BRAF/MEKi), anti-PD-1 monotherapy (Anti-PD-1), and nivolumab plus ipilimumab (PD-1/CTLA-4) between 2016 and 2021 from 28 institutions in Japan. RESULTS We identified 336 patients treated with BRAF/MEKi (n = 236), Anti-PD-1 (n = 64) and PD-1/CTLA-4 (n = 36). The median follow-up duration was 19.9 months for all patients and 28.6 months for the 184 pa tients who were alive at their last follow-up. For patients treated with BRAF/MEKi, anti-PD-1, PD-1/CTLA-4, the median ages at baseline were 62, 62, and 53 years (p = 0.03); objective response rates were 69%, 27%, and 28% (p < 0.001); median progression-free survival (PFS) was 14.7, 5.4, and 5.8 months (p = 0.003), and median overall survival (OS) was 34.6, 37.0 months, and not reached, respectively (p = 0.535). In multivariable analysis, hazard ratios (HRs) for PFS of Anti-PD-1 and PD-1/CTLA-4 compared with BRAF/MEKi were 2.30 (p < 0.001) and 1.38 (p = 0.147), and for OS, HRs were 1.37 (p = 0.111) and 0.56 (p = 0.075), respectively. In propensity-score matching, BRAF/MEKi showed a tendency for longer PFS and equivalent OS with PD-1/CTLA-4 (HRs for PD-1/CTLA-4 were 1.78 [p = 0.149]) and 1.03 [p = 0.953], respectively). For patients who received second-line treatment, BRAF/MEKi followed by PD-1/CTLA-4 showed poor survival outcomes. CONCLUSIONS The superiority of PD-1/CTLA-4 over BRAF/MEKi appears modest in Asian patients. First-line BRAF/MEKi remains feasible, but it is difficult to salvage at progression. Ethnicity should be considered when selecting systemic therapies until personalized biomarkers are available in daily practice. Further studies are needed to establish the optimal treatment sequence for Asian patients.

Abstract
BACKGROUND Extramammary Paget disease (EMPD) is a cutaneous neoplasm that can metastasize to the lymph nodes and distant organs, resulting in a poor prognosis. For unresectable distant metastases of EMPD, no consensus has been reached regarding optimal chemotherapy owing to a lack of data. OBJECTIVES To evaluate the efficacy of three regimens: docetaxel (DTX) monotherapy; combination therapy with 5-fluorouracil, epirubicin, carboplatin, vincristine and mitomycin C (FECOM); and tegafur (S-1) monotherapy. METHODS This single-centre retrospective study included 32 patients diagnosed with unresectable EMPD and treated with chemotherapy between 2002 and 2022 at the National Cancer Center Hospital in Japan. Patient characteristics, responses to treatment and survival data were evaluated for each of the first-line therapies. RESULTS Among the 17 patients who received DTX monotherapy, the response rate (RR) and disease control rate (DCR) were 47% and 77%, respectively. The median progression-free survival (PFS) and overall survival (OS) were 12.3 months [95% confidence interval (CI) 6.1-26.6] and 19.2 months (95% CI 8.5-not reached), respectively. Among the 11 patients who received combination FECOM chemotherapy, the RR and DCR were 55% and 64%, respectively. The median PFS and OS were 6.8 months (95% CI 3.5-not reached) and 13.4 months (95% CI 8.6-21.3), respectively. Among the four patients who received S-1 monotherapy, the RR and DCR were 0% and 25%, respectively. The median PFS and OS were 5.4 months (95% CI 2.3-not reached) and 12.5 (95% CI 2.3-not reached) months, respectively. CONCLUSIONS Further investigations with prospective analysis are required to confirm these findings.

Abstract
Merkel cell carcinoma is a highly aggressive skin cancer characterized by neuroendocrine differentiation. This review aimed to present updates on the knowledge and current trends of clinical management of Merkel cell carcinoma. Additionally, we focused on Asian reports of Merkel cell carcinoma because most skin cancers differ substantially between Caucasians and Asians, and researchers have reported differences in Merkel cell carcinoma in racial and ethnic groups. Owing to its rarity, there is limited evidence for the epidemiology, pathogenesis, diagnosis and Merkel cell carcinoma treatment. The development of a nationwide survey or cancer registry, the identification of Merkel cell polyomavirus and the use of immune checkpoint inhibitors allowed a better understanding of its characteristics and biology and have revolutionized the clinical management of patients with Merkel cell carcinoma. Its incidence has gradually increased worldwide; however, it depends on the geographic location, race and ethnicity. No randomized prospective studies have evaluated the significance of sentinel lymph node biopsy, complete lymph node dissection and adjuvant radiation therapy; however, most patients with localized Merkel cell carcinoma are treated surgically or with post-operative radiation. Patients with distant Merkel cell carcinoma are administered immune checkpoint inhibitors as the first-line therapy; however, there is no established second-line therapy for refractory Merkel cell carcinoma. Furthermore, it is necessary to validate the favorable results of clinical studies performed in Western countries in the patients in Asia.

Abstract
Skin cancer is most frequently diagnosed in the White population. However, its subtypes and epidemiology in Japan are understudied. We aimed to elucidate skin cancer incidence in Japan based on the National Cancer Registry, a new nationwide integrated population-based registry. Data from patients diagnosed with skin cancer in 2016 and 2017 were extracted and classified by cancer subtypes. Data were analyzed using the World Health Organization and General Rules tumor classifications. Tumor incidence was calculated as the number of new cases divided by the corresponding total person-years. Overall, 67,867 patients with skin cancer were included. The percentage of each subtype was as follows: basal cell carcinoma, 37.2%; squamous cell carcinoma, 43.9% (18.3% of which, in situ); malignant melanoma, 7.2% (22.1% of which, in situ); extramammary Paget's disease, 3.1% (24.9% of which, in situ); adnexal carcinoma, 2.9%; dermatofibrosarcoma protuberans, 0.9%; Merkel cell carcinoma, 0.6%; angiosarcoma, 0.5%; and hematologic malignancies, 3.8%. The overall age-adjusted incidence of skin cancer was 27.89 for the Japanese population model and 9.28 for the World Health Organization (WHO) model. The incidences of basal cell carcinoma and squamous cell carcinoma were the highest (3.63 and 3.40 per 100,000 persons, respectively, in the WHO model) among skin cancers, whereas the incidences of angiosarcoma and Merkel cell carcinoma were the lowest (0.026 and 0.038 per 100,000 persons, respectively, in the WHO model). This is the first report to provide comprehensive information on the epidemiological status of skin cancers in Japan using population-based NCR data.

Abstract
We present a mild case of Cockayne syndrome that was referred to us with an extreme sunburn at the age of 3. In early teens, although her cutaneous symptoms alleviated without any medications, she developed tremor and dysarthria. Neurological examination and brain imaging suggested demyelination disorders. The patient's cells indicated a reduced recovery of RNA synthesis, which was partially restored by the introduction of CSB (Cockayne Syndrome B)-cDNA. In addition, her cells indicated a substantially reduced level of CSB protein. Despite the insidious progression of neurological symptoms, she gave birth to a child. Such mild cases of Cockayne syndrome may be misdiagnosed.

Abstract
The efficacy and safety of nivolumab and ipilimumab (N + I) combination therapy for Japanese patients with advanced unresectable melanoma was re-evaluated in clinical practice. One hundred Japanese patients with advanced melanoma were included. The overall response rate was 24%; complete response (CR), 6%; partial response, 18%. The response rates were 33.3% in the systemic therapy-naïve and 15.4% in the prior-treatment groups, and 16.1% for patients who were treated with first-line anti-programmed death 1 antibody monotherapy followed by second-line N + I therapy after progression of the disease. The response rate for cutaneous melanoma was 32.7%, and 47.8% in the naïve group. Response rates for non-acral, acral, and mucosal melanoma were 34.9%, 25%, and 16.7%, respectively. The median progression-free survival (PFS) for all patients was 3.25 months (6.5 and 2.5 months in the naïve and prior-treatment groups, respectively). Median overall survival (OS) was 14.5 months (25.25 and 7.5 months in the naïve and prior-treatment groups, respectively). There were no significant differences in PFS or OS for patients with non-acral, acral, or mucosal melanoma. The 3-year PFS and OS were both 100% in patients who achieved CR with combination therapy. Adverse events occurred in 89% and were grade three or higher in 56% of cases. Although direct comparisons cannot be made due to different patient backgrounds, N + I combination therapy in Japanese patients in clinical practice tended to be inferior when compared to global study and non-Asian patients in clinical practice. The highest response rate was in the cutaneous melanoma therapy-naïve group. The best tumor response was associated with survival outcome, and the PFS and OS were good in cases where CR was obtained. The proportion of grade three and four adverse events was as high as that in the global study.

Abstract
Congenital disorders characterized by the quantitative and qualitative reduction in the number of functional nephrons are the primary cause of chronic kidney disease (CKD) in children. We aimed to describe the alteration of urinary extracellular vesicles (uEVs) associated with decreased renal function during childhood. By nanoparticle tracking analysis and quantitative proteomics, we identified differentially expressed proteins in uEVs in bilateral renal hypoplasia, which is characterized by a congenitally reduced number of nephrons. This expression signature of uEVs reflected decreased renal function in CKD patients by congenital anomalies of the kidney and urinary tract or ciliopathy. As a proof-of-concept, we constructed a prototype ELISA system that enabled the isolation of uEVs and quantitation of expression of molecules representing the signature. The system identified decreased renal function even in its early stage. The uEVs signature could pave the way for non-invasive methods that can complement existing testing methods for diagnosing kidney diseases. Urinary extracellular vesicles (uEVs) are altered in chronic kidney disease (CKD) Characteristic expression signatures associated with childhood CKD are identified An ELISA utilizing the signature detected decreased renal function uEVs signature has potential in diagnosing kidney diseases

Abstract
Abstract
Study question
How do the blastomeres formed by direct cleavage (dynamics of one cell dividing into three or more cells) subsequently develop?
Summary answer
About half of the blastomeres by direct cleavage did not form blastocysts.
What is known already
There are many reports that embryos with direct cleavage in the early development have a lower blastocyst development rate because direct cleavage produces chromosomal abnormal cells. However, when such embryos develop into blastocysts, there have been some reports that the transfer pregnancy rate and euploid rate did not decrease, but the reasons for this have not been clarified.
Study design, size, duration
This is a retrospective study of 89 blastocysts obtained during 2013-18. These embryos were those that patients requested to be discarded and consented to be used in this study. All target embryos were time-lapse monitored by EmbryoScope (Vitrolife, Sweden), and several trophectoderms were biopsied and examined for euploidy.
Participants/materials, setting, methods
The target embryos were classified into three groups: embryos with normal first and second cleavage (NC group), embryos with irregular division (one cell dividing into three or more cells) called direct cleavage at the first cleavage (DC1 group), and embryos with direct cleavage of one blastomere at the second cleavage (DC2 group). It was recorded whether the blastomeres of the embryos subsequently developed into blastocysts or not. NGS analysis was performed on the embryos.
Main results and the role of chance
The target embryos were classified as 48 in the NC group, 32 in the DC1 group, and 9 in the DC2 group. Whether the blastomeres in the target embryos subsequently formed blastocysts or not was recorded one by one by time-lapse images, resulting in the blastomeres’ blastocyst formation rate was 95.1% in the NC group and 55.9% in the DC1 group, which was significantly lower in the DC1 group (P < 0.01). In the DC2 group, blastomeres formed by normal division and those by direct cleavage at the second cleavage were recorded separately, and the blastocyst formation rate was 90.8% for normal cleavage blastomeres and 46.0% for direct cleavage blastomeres, with significantly lower rates for direct cleavage blastomeres (P < 0.01). Therefore, about half of the blastomeres generated by direct cleavage at the first or second cleavage did not form blastocysts. The results of NGS analysis were as follows: NC group: 35.4% euploid, 45.8% aneuploid, and 18.8% mosaic; DC1 group: 37.5%, 53.1%, and 9.4%, respectively; and DC2 group: 55.6%, 33.3%, and 11.1%, respectively. There was no significant difference in any of the items, suggesting that direct cleavage does not affect the euploidy of blastocysts.
Limitations, reasons for caution
For the purpose of NGS analysis, all the target embryos in this study were blastocysts, but if all the cultured embryos were included, arrested embryos would be included, which would probably result in more blastomeres formed by direct cleavage not developing into blastocysts.
Wider implications of the findings
The blastomeres generated by direct cleavage were often excluded from blastocyst formation. This may be an exclusion of chromosomally abnormal cells and may be one of the reasons why direct cleavage decreases blastocyst development rate but does not decrease blastocyst euploid rate.

Abstract
e21553 Background: The systemic treatment for advanced BRAF-mutant melanoma includes BRAF/MEK inhibitors (BRAF/MEKi), anti-PD-1 monotherapy (aPD1), and the combination of nivolumab plus ipilimumab (NIVO/IPI). Several studies have demonstrated favorable survival benefits for those treated with immunotherapy upfront. Most of these studies, however, were conducted among Caucasian-dominant cohorts; evidence for Asian patients is limited. Therefore, our objective was to assess the efficacy of first-line therapies for Asian patients in a real-world setting. Methods: We retrospectively collected the clinical data of Asian patients with advanced BRAF-mutant melanoma treated with first-line BRAF/MEKi, aPD1, or NIVO/IPI from 26 institutions in Japan. Clinical outcomes were determined by assessing the objective response rate (ORR), progression-free survival (PFS), and overall survival (OS) by first-line therapies. Kaplan‐Meier curves and log‐rank tests, as well as multivariable Cox proportional hazard models were used to estimate survival probabilities. Results: We identified 316 Asian patients treated with first-line BRAF/MEKi (n = 224), aPD1 (n = 59), or NIVO/IPI (n = 33) between 2016 and 2021. At baseline, the median age of the patients in each treatment arm was 63, 62, and 54, respectively (p = 0.053). The ORR in the first-line therapy was 69%, 29%, and 27%, respectively (p < 0.001). With a median follow-up of 18.9 months, the median PFS was 16.2, 5.6, and 6.4 months (p = 0.001); and the median OS was 36.9, 37.9 months, and not reached (p = 0.386), respectively. In a multivariable analysis, the predictive factors of short PFS were first-line therapy with aPD1 (HR, 2.44; 95%CI, 1.70-3.50, p < 0.001) or NIVO/IPI (1.73; 1.06–2.83, p = 0.029), BRAF V600K (p = 0.031), ECOG PS ≥2 (p = 0.011), elevated lactate dehydrogenase (LDH) levels (p = 0.001), and M1a/M1c/M1d stages (p = 0.036/ < 0.001/ < 0.001, respectively). Predictive factors of short OS were BRAF V600K (p = 0.042), ECOG PS ≥2 (p = 0.001), elevated LDH levels (p < 0.001), and M1c/M1d stages (both p < 0.001). The OS did not differ significantly by first-line therapies between BRAF/MEKi, aPD1 (1.52; 0.98–2.34, p = 0.061), and NIVO/IPI (0.63; 0.31–1.27, p = 0.194). Conclusions: Although upfront NIVO/IPI showed the longest OS numerically, its superiority over BRAF/MEKi in Asian patients seems to be modest compared with Caucasian patients. Because upfront BRAF/MEKi showed an OS that was comparable with that of aPD1, BRAF/MEKi remains an active first-line therapy option, especially for those who are not amenable to take the high risk of immune-related toxicities.

Abstract
We present stability and structure of two-and three-alpha systems embedded in dilute cold neutron matter. By solving a few-alpha Schrödinger equation with quasiparticle properties, i.e.,effective mass and induced two-and three-alpha interactions, which are evaluated in terms of Fermi polarons,itis shown that 8Be and the Hoyle state become bound at densities of about10−4 and 10−3 of the saturation density, respectively. It is also seen that, under cold neutron matter environment, both systems become smaller than the corresponding systems in vacuum. Our results would affect astrophysical models for stellar collapse and neutron star mergers, as well as relevant reaction rates for nucleosynthesis.

Abstract
To establish real-world evidence about the safety and efficacy of bexarotene for Japanese patients with cutaneous T-cell lymphoma, we conducted a nationwide cohort study using data from post-marketing surveillance for bexarotene treatment. In total, 294 patients with cutaneous T-cell lymphoma were identified between June 2016 and June 2018. Of these, 267 patients were included as the safety analysis set. Of the 267 patients, 175 were included in the efficacy analysis set. Of these, 139 patients had mycosis fungoides, including 46 with early stage disease and 93 with advanced stage disease. Among the 139 patients with mycosis fungoides, the objective response rate was 46.8%. A significant difference in objective response rate was detected between patients who started with bexarotene at 300 mg/m2 (61.6%) and patients who started with bexarotene at less than 300 mg/m2 (22.6%, p < 0.001). Of the 139 patients with mycosis fungoides, 92 were treated with a combination of bexarotene plus photo(chemo)therapy. A significant difference in objective response rate was seen between bexarotene with a combination of photo(chemo)therapy (57.6%) and bexarotene without a combination of photo(chemo)therapy (25.5%, p < 0.001). Starting bexarotene at 300 mg/m2 and combination with photo(chemo)therapy were detected as independent factors influencing response. Common treatment-related adverse events included hypothyroidism (85.8%), hypertriglyceridemia (68.5%), hypercholesterolemia (43.8%), and neutropenia (21.3%). Hypertriglyceridemia, hypercholesterolemia, and neutropenia occurred more frequently in patients who started with bexarotene at 300 mg/m2 than patients who started with bexarotene at less than 300 mg/m2 (hypertriglyceridemia, 76.4% vs. 57.0%, p = 0.001; hypercholesterolemia, 49.0% vs. 36.4%, p = 0.045; neutropenia, 28.0% vs. 12.1%, p = 0.002; respectively). The present study indicates that starting bexarotene at 300 mg/m2 and combination of photo(chemo)therapy offer a promising efficacy for the treatment of patients with mycosis fungoides. Efficacy of low-dose bexarotene plus photo(chemo)therapy should be evaluated in future.

Abstract
Abstract
Study question
When does blastomere exclusion from compaction increase and what effect does it have on the embryo?
Summary answer
More blastomere were excluded from compaction in embryos with irregular cleavage, resulting in lower blastocyst development rates, but no decrease in pregnancy rates at transfer.
What is known already
It has been reported that many of the chromosome analysis results of blastomere excluded from compaction were aneuploid, and pointed out that this exclusion may be related to the repair of blastocyst euploidy, but the effect of the number of excluded blastomere has not been reported.
Study design, size, duration
This is a retrospective study of 578 embryos that developed into morula with time-lapse monitoring by EmbryoScope (Vitrolife) in 2018–2019.
Participants/materials, setting, methods
The target embryos were classified into two groups: embryos with normal first and second cleavage (normal cleavage group) and embryos with irregular cleavage (dynamics of one cell dividing into three or more cells), called “direct cleavage”, at either cleavage (DC group), and the number of blastomere excluded from compaction during morula formation was recorded and compared. The blastocyst development rate and single blastocyst transfer pregnancy rates of the two groups were compared.
Main results and the role of chance
There are 286 in the normal cleavage group and 292 in the DC group. The mean number of excluded blastomere was 0.76 and 3.55, respectively, which was significantly higher in the DC group (P < 0.01). Good blastocyst (Gardner classification 4 or higher) development rate was 84.5% (239/283) and 65.8% (181/275), respectively, and high grade blastocyst (Gardner classification BB or higher) development rate was 43.9% (105/239) and 14.9% (27/181) of them, both significantly higher in the normal cleavage group (P < 0.01). The single blastocyst transfer pregnancy rates were 31.6% (25/79) and 32.4% (11/34), and the miscarriage rates were 24.0% (6/25) and 27.3% (3/11), respectively, neither was there a significant difference between the two groups. So, direct cleavage increased the number of blastomere excluded from compaction, decreased the rate of morula to good blastocyst development and reduced blastocyst grade, but did not affect blastocyst transfer pregnancy rate and miscarriage rate.
Limitations, reasons for caution
Please note that all target embryos must have developed into morula or larger (embryos that did not develop into morula will not be included in the study).
Wider implications of the findings: Severe chromosomal aberrant blastomeres formed by direct cleavage were excluded from compaction, and the blastocyst development rate decreased due to a decrease in the amount of viable cells, but it is suggested that this blastomere exclusion mechanism is not related to euploidy after blastocyst development.

Abstract
We report the first evidence for X(3872) production in two-photon interactions by tagging either the electron or the positron in the final state, exploring the highly virtual photon region. The search is performed in e^{+}e^{-}→e^{+}e^{-}J/ψπ^{+}π^{-}, using 825 fb^{-1} of data collected by the Belle detector operated at the KEKB e^{+}e^{-} collider. We observe three X(3872) candidates, where the expected background is 0.11±0.10 events, with a significance of 3.2σ. We obtain an estimated value for Γ[over ˜]_{γγ}B(X(3872)→J/ψπ^{+}π^{-}) assuming the Q^{2} dependence predicted by a cc[over ¯] meson model, where -Q^{2} is the invariant mass squared of the virtual photon. No X(3915)→J/ψπ^{+}π^{-} candidates are found.

Abstract
The efficacy and safety of nivolumab + ipilimumab combination therapy were retrospectively examined in Japanese patients with unresectable advanced melanoma in clinical practice. Fifty-seven patients with advanced melanoma received the nivolumab + ipilimumab combination therapy. The primary site was cutaneous, mucosal, uveal and unknown in 35, 16, two and four patients, respectively. The overall response rate was 26.3%, with complete response observed in two (3.5%) patients, partial response in 13 (22.8%), stable disease in 12 (21.1%) and progressive disease in 30 (52.6%). The response rate in the treatment-naive and prior systemic therapy group was 40.7% and 13.3%, respectively. For those treated with a single immune checkpoint inhibitor followed by the nivolumab + ipilimumab combination therapy as second-line therapy after disease progression, the response rate was 18.8%. Median progression-free survival (PFS) and overall survival (OS) in all patients was 3.3 and 14 months, respectively. Median PFS in the treatment-naive and prior systemic therapy groups was 13 and 2 months, respectively. Median OS was unreached in the treatment-naive group and was 6.3 months in prior systemic therapy groups. There was no significant difference in PFS and OS for non-acral, acral and mucosal melanoma. Adverse events occurred in 86% of patients; 56.1% were grade 3 or worse. The response rate in an actual clinical setting, including the prior systemic therapy group, was lower than that in the global study and the Japanese phase II study. However, in the treatment-naive group, the rate was equivalent to that in the Japanese phase II study. PFS and OS in the treatment-naive group were comparable with those in the global study and Japanese phase II study, suggesting that the treatment was effective. The proportion of grade 3 and 4 immune-related adverse events was as high as that in the global study and Japanese phase II study.

Abstract
Background Paclitaxel is a standard of care for patients with primary cutaneous angiosarcoma of the scalp and face. However, no standard second-line treatment for paclitaxel-resistant patients has ever been established. Since primary cutaneous angiosarcoma expresses a high level of vascular endothelial growth factor receptor, the multitargeted tyrosine kinase inhibitor pazopanib seemed to be the most promising agent, and several retrospective studies have demonstrated its activity against this disease. However, the efficacy and safety of pazopanib in paclitaxel-resistant patients with primary cutaneous angiosarcoma have never been evaluated in a clinical trial. Methods In February 2018 the Dermatologic Oncology Group of Japan Clinical Oncology Group started a single-arm confirmatory trial to evaluate the efficacy and safety of pazopanib as a second-line treatment for patients with primary cutaneous angiosarcoma whose disease was resistant to paclitaxel or who were unable to tolerate paclitaxel (JCOG1605, JCOG-PCAS). Patients with primary cutaneous angiosarcoma not associated with lymphedema or radiation, progressing despite first-line paclitaxel monotherapy are included in the study. No prior systemic chemotherapy other than paclitaxel is permitted. Pazopanib is administered orally at an initial dosage of 800 mg once daily. Dose modifications for adverse events are made according to the dose reduction criteria described in the protocol. Treatment is continued until recurrence, disease progression, unacceptable toxic effects, patient refusal, or death. The primary endpoint is progression-free survival, secondary endpoints include overall survival, response rate, disease control rate, adverse events, and serious adverse events. We plan to recruit 30 participants in 5.5 years from 23 Japanese institutions. The follow-up period is set as 1 year after completion of accrual. The study protocol was approved by the Japan Clinical Oncology Group Protocol Review Committee in December 2017. Ethical approval for this study was granted by Ethics Committee of each institute. Discussion If the primary endpoint is met, pazopanib will be regarded as a standard of care for paclitaxel-resistant patients for whom no standard second-line treatment is established. Trials registration Registry number: UMIN000031438 [http://www.umin.ac.jp/ctr/index.htm]. Date of Registration: 23/Feb/2018. Date of First Participant Enrollment: 8/Mar/2018.

Abstract
Theories beyond the standard model often predict the existence of an additional neutral boson, the Z^{'}. Using data collected by the Belle II experiment during 2018 at the SuperKEKB collider, we perform the first searches for the invisible decay of a Z^{'} in the process e^{+}e^{-}→μ^{+}μ^{-}Z^{'} and of a lepton-flavor-violating Z^{'} in e^{+}e^{-}→e^{±}μ^{∓}Z^{'}. We do not find any excess of events and set 90% credibility level upper limits on the cross sections of these processes. We translate the former, in the framework of an L_{μ}-L_{τ} theory, into upper limits on the Z^{'} coupling constant at the level of 5×10^{-2}-1 for M_{Z^{'}}≤6 GeV/c^{2}.

Abstract
We report the first observation of the radiative decay of the ϒ(1S) into a charmonium state. The significance of the observed signal of ϒ(1S)→γχ_{c1} is 6.3 standard deviations including systematics. The branching fraction is calculated to be B[ϒ(1S)→γχ_{c1}]=[4.7_{-1.8}^{+2.4}(stat)_{-0.5}^{+0.4}(sys)×10^{-5}]. We also searched for ϒ(1S) radiative decays into χ_{c0,2} and η_{c}(1S,2S), and set upper limits on their branching fractions. These results are obtained from a 24.9 fb^{-1} data sample collected with the Belle detector at the KEKB asymmetric-energy e^{+}e^{-} collider at a center-of-mass energy equal to the ϒ(2S) mass using ϒ(1S) tagging by the ϒ(2S)→ϒ(1S)π^{+}π^{-} transitions.

Abstract
Combination therapy with nivolumab + ipilimumab was recently approved for treating unresectable cases of malignant melanoma. In spite of the high response rate, it is associated with a high incidence of serious adverse events, including immune-related hemophagocytic syndrome/hemophagocytic lymphohistiocytosis (irHPS/HLH), a difficult to diagnose rare disease. This is the first report of this disease in an Asian malignant melanoma patient treated with nivolumab + ipilimumab. A 69-year-old Japanese woman with unresectable malignant melanoma was treated with nivolumab + ipilimumab. Following the combined therapy, her fever and symptoms of malaise occurred, and she visited to our hospital's emergency department. Blood tests revealed significant liver dysfunction, anemia, and thrombocytopenia. We suspected irHPS/HLH, based on tests revealing decreased fibrinogen and significantly increased ferritin. Bone marrow biopsy revealed numerous macrophages and high hemophagocytosis levels. After 50 mg prednisolone (1 mg/kg per day) was administered, fever and cytopenia markedly improved. irHPS/HLH has a high rate of coagulation abnormalities accompanied by hypertriglyceridemia and hypofibrinogenemia, which are unlikely to occur in adult HPS/HLHs. Because irHPS/HLH responds better to steroids than other secondary HPS/HLHs, we expect a complete cure with steroids. Quick diagnosis and appropriate treatment based on clinical symptoms and laboratory tests are needed in suspected cases.

Abstract
Keratoacanthoma centrifugum marginatum (KCM) is a rare variant of keratoacanthoma. This condition is difficult to diagnose because of its large size and expansive nature and may be diagnosed as a malignant tumor. There are various treatments such as surgery and oral retinoids; however, limited studies have verified their effectiveness. Here, we report a case of KCM on the anterior chest of a 50-year-old woman and evaluate the efficacy of oral retinoids. In this case, oral retinoids were highly effective for KCM treatment. A total of 55 cases of KCM, including 54 previously reported cases, were reviewed, and their clinical characteristics and treatment were examined. In this report, 14 of 16 patients were effectively treated with oral retinoids, resulting in a treatment rate of 87.5%. Furthermore, even low-to-medium doses were sufficient for treatment and prevention. KCM can be misdiagnosed as a malignant disease based on its clinical features. Due to its large size and expansive nature, a wide excision may be performed; however, because oral retinoids have a very high response rate, an accurate diagnosis will help avoid an unnecessary wide excision.

Abstract
Treatment for patients with unresectable melanoma has been dramatically changed by the use of immunocheckpoint inhibitors (ICI). In this study, we reviewed patients with unresectable stage III/IV melanoma, who were treated with nivolumab between July 2014 and March 2017 at the Department of Dermatologic Oncology, National Cancer Center Hospital, Tokyo, and retrospectively recorded cutaneous adverse events (cAE), development of vitiligo, clinical characteristics and clinical responses. We identified 128 patients, 61 (47.7%) of whom showed cAE, including 30 (23.4%) with development or exacerbation of vitiligo. The prognosis of patients with melanoma treated with ICI correlated with cAE, including development of vitiligo. Patients with cAE showed better objective responses (41.0% vs 6.0%, P < 0.001), progression-free survival (PFS) (377 vs 61 days, P < 0.001) and overall survival (OS) (763 vs 209 days, P < 0.001) than did patients without cAE. Patients who developed vitiligo showed better objective responses (53.3% vs 29.0% vs 6.0%, P < 0.001), PFS (median, not reached vs 317 vs 65 days, P < 0.001) and OS (not reached vs 689 vs 209 days, P < 0.001) than did patients with other cAE and patients without cAE. Landmark analysis showed development of vitiligo starting 20 weeks after starting nivolumab correlated with better OS. In multivariate analysis, OS correlated with performance status, number of metastasized organs, cAE other than vitiligo and development of vitiligo. Despite the fact that the correlation between other cAE and OS was less than that of vitiligo, cAE may be a simple marker of favorable prognosis.

Abstract
We conducted a retrospective investigation of the efficacy and safety of dabrafenib and trametinib combination therapy in Japanese patients with BRAF V600 mutation-positive advanced melanoma in real-world clinical practise. The study analyzed 50 patients who received dabrafenib and trametinib combination therapy for BRAF V600 mutation-positive advanced melanoma in our hospital (26 men and 24 women, aged 21-86 years, inclusive; median age, 53 years). The response rate was 72.3%, with complete response (CR) achieved in eight cases (17.0%), partial response in 26 (55.3%), stable disease in nine (19.1%) and progressive disease in four (8.5%). Median progression-free survival (PFS) was 12 months, and median overall survival (OS) was 23 months. Disease progression occurred in 29 of the 50 patients during the study period, and 25 patients died. Baseline lactate dehydrogenase and the number of organs with metastasis were important predictive factors for PFS and OS, and CR to combination therapy was a predictive factor for long-term remission. Adverse events occurred in 88% of cases; 16% were grade 3 or worse. The adverse events observed in 50% of more of patients were rash (56%) and pyrexia (52%). The efficacy of dabrafenib and trametinib combination therapy in Japanese patients was similar to that reported in global studies, and the same adverse events were generally reported; however, rash tended to occur more frequently in the patients in our study.

Abstract
We present the first measurements of absolute branching fractions of Ξ_{c}^{0} decays into Ξ^{-}π^{+}, ΛK^{-}π^{+}, and pK^{-}K^{-}π^{+} final states. The measurements are made using a dataset comprising (772±11)×10^{6} BB[over ¯] pairs collected at the ϒ(4S) resonance with the Belle detector at the KEKB e^{+}e^{-} collider. We first measure the absolute branching fraction for B^{-}→Λ[over ¯]_{c}^{-}Ξ_{c}^{0} using a missing-mass technique; the result is B(B^{-}→Λ[over ¯]_{c}^{-}Ξ_{c}^{0})=(9.51±2.10±0.88)×10^{-4}. We subsequently measure the product branching fractions B(B^{-}→Λ[over ¯]_{c}^{-}Ξ_{c}^{0})B(Ξ_{c}^{0}→Ξ^{-}π^{+}), B(B^{-}→Λ[over ¯]_{c}^{-}Ξ_{c}^{0})B(Ξ_{c}^{0}→ΛK^{-}π^{+}), and B(B^{-}→Λ[over ¯]_{c}^{-}Ξ_{c}^{0})B(Ξ_{c}^{0}→pK^{-}K^{-}π^{+}) with improved precision. Dividing these product branching fractions by the result for B^{-}→Λ[over ¯]_{c}^{-}Ξ_{c}^{0} yields the following branching fractions: B(Ξ_{c}^{0}→Ξ^{-}π^{+})=(1.80±0.50±0.14)%, B(Ξ_{c}^{0}→ΛK^{-}π^{+})=(1.17±0.37±0.09)%, and B(Ξ_{c}^{0}→pK^{-}K^{-}π^{+})=(0.58±0.23±0.05)%. For the above branching fractions, the first uncertainties are statistical and the second are systematic. Our result for B(Ξ_{c}^{0}→Ξ^{-}π^{+}) can be combined with Ξ_{c}^{0} branching fractions measured relative to Ξ_{c}^{0}→Ξ^{-}π^{+} to yield other absolute Ξ_{c}^{0} branching fractions.

Abstract
We report the first observation of the double strange baryon Ξ(1620)^{0} in its decay to Ξ^{-}π^{+} via Ξ_{c}^{+}→Ξ^{-}π^{+}π^{+} decays based on a 980 fb^{-1} data sample collected with the Belle detector at the KEKB asymmetric-energy e^{+}e^{-} collider. The mass and width are measured to be 1610.4±6.0(stat)_{-4.2}^{+6.1} (syst) MeV/c^{2} and 59.9±4.8(stat)_{-7.1}^{+2.8}(syst) MeV, respectively. We obtain 4.0σ evidence of the Ξ(1690)^{0} with the same data sample. These results shed light on the structure of hyperon resonances with strangeness S=-2.

Abstract
We report on the first Belle search for a light CP-odd Higgs boson, A^{0}, that decays into low mass dark matter, χ, in final states with a single photon and missing energy. We search for events produced via the dipion transition ϒ(2S)→ϒ(1S)π^{+}π^{-}, followed by the on-shell process ϒ(1S)→γA^{0} with A^{0}→χχ, or by the off-shell process ϒ(1S)→γχχ. Utilizing a data sample of 157.3×10^{6} ϒ(2S) decays, we find no evidence for a signal. We set limits on the branching fractions of such processes in the mass ranges M_{A^{0}}<8.97 GeV/c^{2} and M_{χ}<4.44 GeV/c^{2}. We then use the limits on the off-shell process to set competitive limits on WIMP-nucleon scattering in the WIMP mass range below 5 GeV/c^{2}.

Abstract
We present first evidence that the cosine of the CP-violating weak phase 2β is positive, and hence exclude trigonometric multifold solutions of the Cabibbo-Kobayashi-Maskawa (CKM) Unitarity Triangle using a time-dependent Dalitz plot analysis of B^{0}→D^{(*)}h^{0} with D→K_{S}^{0}π^{+}π^{-} decays, where h^{0}∈{π^{0},η,ω} denotes a light unflavored and neutral hadron. The measurement is performed combining the final data sets of the BABAR and Belle experiments collected at the ϒ(4S) resonance at the asymmetric-energy B factories PEP-II at SLAC and KEKB at KEK, respectively. The data samples contain (471±3)×10^{6}BB[over ¯] pairs recorded by the BABAR detector and (772±11)×10^{6}BB[over ¯] pairs recorded by the Belle detector. The results of the measurement are sin2β=0.80±0.14(stat)±0.06(syst)±0.03(model) and cos2β=0.91±0.22(stat)±0.09(syst)±0.07(model). The result for the direct measurement of the angle β of the CKM Unitarity Triangle is β=[22.5±4.4(stat)±1.2(syst)±0.6(model)]°. The measurement assumes no direct CP violation in B^{0}→D^{(*)}h^{0} decays. The quoted model uncertainties are due to the composition of the D^{0}→K_{S}^{0}π^{+}π^{-} decay amplitude model, which is newly established by performing a Dalitz plot amplitude analysis using a high-statistics e^{+}e^{-}→cc[over ¯] data sample. CP violation is observed in B^{0}→D^{(*)}h^{0} decays at the level of 5.1 standard deviations. The significance for cos2β>0 is 3.7 standard deviations. The trigonometric multifold solution π/2-β=(68.1±0.7)° is excluded at the level of 7.3 standard deviations. The measurement resolves an ambiguity in the determination of the apex of the CKM Unitarity Triangle.

Abstract
Xeroderma pigmentosum (XP) is a rare autosomal recessive hereditary disease caused by deficiency in repair of DNA lesions generated by ultraviolet radiation and other compounds. Patients with XP display pigmentary change and numerous skin cancers in sun-exposed sites, and some patients show exaggerated severe sunburns even upon minimum sun exposure as well as neurological symptoms. We conducted a nationwide survey for XP since 1980. In Japan, the frequency of the XP complementation group A is the highest, followed by the variant type; while in the Western countries, those of groups C or D are the highest. Regarding skin cancers in XP, basal cell carcinoma was the most frequent cancer that afflicted patients with XP, followed by squamous cell carcinoma, and malignant melanoma. The frequency of these skin cancers in patients with XP has decreased in these 20 years, and the age of onset of developing skin cancers is higher than those previously observed, owing to early diagnosis and education to patients and care takers on strict prevention from sunlight for patients with XP. On the other hand, the effective therapy for neurological XP has not been established yet, and this needs to be done urgently.

Abstract
Mycosis fungoides (MF) has been reported to be the most common cutaneous lymphoma with a good prognosis and myocardial infiltration is clinically rare. We hereby report a case of rapidly progressing acute heart failure due to myocardial infiltration by MF. Perfusion cardiac magnetic resonance imaging (MRI) demonstrated a massive perfusion defect in the left ventricle (LV) where multiple nodular enhancement areas by delayed enhancement MRI could be documented in the postero-lateral wall of the LV, which resulted in a deterioration of the LV function and mitral regurgitation. Autopsy confirmed the myocardial infiltration by the MF, which corresponded with the MRI findings. <Learning objective: Symptomatic heart failure patients with myocardial infiltration by mycosis fungoides (MF) have a poor prognosis because they could not undergo chemotherapy for primary disease. Therefore, early diagnosis is important for improvement of prognosis. The routine assessment of the cardiac involvement by cardiac magnetic resonance imaging as well as transthoracic echocardiography should be performed for an early recognition of myocardial infiltration even in asymptomatic MF patients.>.
