Abstract
BACKGROUND/AIM A subset of patients with estrogen receptor (ER)-positive, HER2-negative, and node-negative breast cancer experience recurrences. Predicting patients who will have recurrences within 5 years of surgery is essential so that patients can be selected to receive adjuvant chemotherapy. The 95-gene classifier (95-GC) has been validated as a method to differentiate patients into high and low-risk groups for early recurrence. PATIENTS AND METHODS In this study, we performed 95-GC analysis on 56 formalin-fixed paraffin-embedded (FFPE) tissue samples from patients who underwent surgery for ER-positive, HER2-negative, and node-negative breast cancer and did not receive adjuvant chemotherapy. We associated the obtained high- and low-risk groups with clinicopathological characteristics and recurrence-free survival (RFS). RESULTS We classified 12 out of 56 patients into the high-risk recurrence group. We found significantly higher KI67 scores in patients in the high-risk group. Other clinicopathological characteristics were not associated with the 95-GC risk groups. Patients in the 95-GC low-risk group had a significantly better prognosis than those in the high-risk group (p=0.0387). The 5-year RFS rate was 97.6% in the low-risk group and 74.1% in the high-risk group, while the 10-year RFS rates were 90.1% and 74.1%, respectively. CONCLUSION The 95-GC score can accurately predict RFS within 5 years of surgery for ER-positive, HER2-negative, and node-negative breast cancer using FFPE tissue samples. These prediction models could help assign patients to the most effective treatment regimen.

Abstract
An experimental implementation for the reduction of power-line noise in delicate signal detection is presented. This implementation improves the signal-to-noise ratio without limiting the bandwidth of the measurement. A sinusoidal wave and its harmonics, both synchronized with the frequency of the power line, are used to cancel out the power supply noise induced in the measurement signal. The wave and the harmonics are generated via a phase-locked loop implementation. Their amplitude and phase are adjusted, and then they are added to the measurement signal using a series of operational amplifiers to compensate for the noise. Although we applied this method to the particular case of scanning tunneling microscopy measurements, considerably improving the image quality, our implementation can be applied to other measurement systems for which noise from the power lines can compromise the signal detection.

Abstract
Abstract
Study question
Does the area of oocyte perivitelline space have an effect on fertilization and embryo development following intracytoplasmic sperm injection?
Summary answer
The area of oocyte perivitelline space has not an effect on the fertilization but the embryo development following intracytoplasmic sperm injection.
What is known already
Oocyte perivitelline space has a lot of variation at intracytoplasmic sperm injection (ICSI). Some researchers reported that the characteristics of perivitelline space (large or small) affect embryo development, pregnancy, and implantation. However, these studies did not accurately calculate the area of perivitelline space. Therefore, little information is available on the effect of the area of oocyte perivitelline space on fertilization and embryo development following ICSI. The purpose of this study was to calculate and classify the area of oocyte perivitelline space and investigate the effect of the area of perivitelline space on fertilization and embryo development following ICSI.
Study design, size, duration
1. We retrospectively investigated 634 mature oocytes that were conducted ICSI between January 2021 and December 2021. The area of each oocyte perivitelline space was defined from between the area of circle calculated from the inner layer of zona pellucida and cytoplasm and divided into 3 groups (-9%, 10-19%, 20%-).
2. We retrospectively calculated the diameter of an inner layer of zona pellucida and cytoplasm and compared it with the 3 groups (-9%, 10-19%, 20%-).
Participants/materials, setting, methods
1. The fertilization, survival, good quality day-3 embryo, blastocyst, good quality blastocyst rates following ICSI were compared with the 3 groups (-9%, 10-19%, 20%-).
2. The average diameter of an inner layer of zona pellucida and cytoplasm of each oocyte for the 3 groups (-9%, 10-19%, 20%-) were compared.
The data were analyzed by Fisher’s exact test, residual analysis, one-way ANOVA test, with Bonferroni correction as appropriate to determine the statistical differences among groups.
Main results and the role of chance
1. The survival rates of perivitelline space -9%, 10-19%, 20%- groups were 100% (109/109), 96% (363/378), 94% (138/147), the fertilization rates were 89% (97/109), 88% (331/378), 86% (127/147), the good quality day-3 embryo rates were 56% (54/97), 70% (232/331), 70% (89/127) respectively. No significant difference was observed between these comparison items. The blastocyst rates of perivitelline space -9%, 10-19%, 20%- groups were 51% (47/92), 69% (222/321), 82% (93/114), the good quality blastocyst rates were 22% (20/92), 40% (129/321), 52% (59/114) respectively. The blastocyst and good quality blastocyst rates of perivitelline space -9% group showed significantly lower results. On the other hand, the blastocyst and good quality blastocyst rates of perivitelline space 20%- group showed significantly higher results.
2. The average diameter of an inner layer of zona pellucida of perivitelline space -9%, 10-19%, 20%- groups were 125 ± 4 µm, 129 ± 5 µm, 136 ± 6 µm, the average diameter of the cytoplasm of perivitelline space were 121 ± 4 µm, 119 ± 4 µm, 118 ± 4 µm respectively. Significant differences were observed in all pairs of groups of the average diameter of an inner layer of zona pellucida and cytoplasm.
Limitations, reasons for caution
The area of oocyte perivitelline space was calculated at only one plane.
Wider implications of the findings
Oocytes with narrow perivitelline space might have a wide region of adhesive between the cytoplasm surface and an inner layer of the zona pellucida which resulted in a smaller diameter of the zona pellucida and lower blastocyst rate by forming cytoplasmic fragments (Yumoto K et al. JARG. 2020 ;37(6):1349-1354.).

Abstract
BACKGROUND The Safari study (UMIN000015168) was a retrospective, multicenter study in which 1072 consecutive cases of estrogen receptor-positive advanced breast cancer treated using 500 mg fulvestrant were registered. We previously reported the relationship between the patient factors and overall survival after the diagnosis using the same cases and the same factors for the analysis of time to treatment failure in patients with estrogen receptor-positive advanced breast cancer. The current study is an ad hoc analysis that focused on the relationship between the patient factors and overall survival after recurrence by adding factors generally associated with overall survival after recurrence. METHODS The overall survival after recurrence in patients with estrogen receptor-positive human epidermal growth factor receptor 2 negative recurrent breast cancer was analyzed via univariate and multivariate analyses with a Cox proportional hazards model. RESULTS A total of 598 cases were used for the analysis of overall survival after recurrence. Multivariate analysis revealed that favorable overall survival (median, 6.4 years) was significantly correlated with long time from recurrence to fulvestrant use (≥3 years), low nuclear or histological grade (G3 vs. G1), long time to treatment failure of initial palliative endocrine therapy (≥12 months) and long time to initial palliative chemotherapy (≥2 years). CONCLUSION The results of this study indicate that sequential endocrine monotherapy may be a useful treatment option for patients with estrogen receptor-positive/human epidermal growth factor receptor 2 negative recurrent breast cancer who have been successfully treated with initial long-term palliative endocrine therapy.

Abstract
The onset of neurodegenerative disorders (NDs), such as Alzheimer's disease, is associated with the accumulation of aggregates of misfolded proteins. We previously showed that chemical knockdown of ND-related aggregation-prone proteins can be achieved by proteolysis targeting chimeras (PROTACs). However, hetero-bifunctional PROTACs generally show poor permeability into the central nervous system, where NDs are located. Here, we document the conversion of one of our PROTACs into hydrophobic tags (HyTs), another class of degraders bearing hydrophobic degrons. This conversion decreases the molecular weight and the number of hydrogen bond donors/acceptors. All the developed HyTs lowered the level of mutant huntingtin, an aggregation-prone protein, with potency comparable to that of the parent PROTAC. Through IAM chromatography analysis and in vivo brain penetration assay of the HyTs, we discovered a brain-permeable HyT. Our results and mechanistic analysis indicate that conversion of protein degraders into HyTs could be a useful approach to improve their drug-like properties.

Abstract
A 23-year-old woman was presented with fever and epigastric pain. Contrast enhanced computed tomography revealed a 40mm mass in the lateral segment. Blood tests showed the elevation of WBC and CRP. With the diagnosis of liver abscess, the antibiotics were administered, and the clinical findings were promptly improved. One year later, she complained of the same symptoms, and the mass had increased to 50mm in diameter. Percutaneous liver biopsy led to the diagnosis of fibrolamellar hepatocellular carcinoma.

Abstract
Cancer cells require oxygen and nutrients for growth, making angiogenesis one of the essential components of tumor growth. Gangliosides, constituting membrane lipid rafts, regulate intracellular signal transduction and are involved in the malignancy of cancer cells. While endothelial cells, as well as cancer cells, express vast amounts of gangliosides, the precise function of endothelial gangliosides in angiogenesis remains unclear. In this study, we focused on gangliosides of vascular endothelial cells and analyzed their functions on tumor angiogenesis. In human breast cancer, GM3 synthase was highly expressed in vascular endothelial cells as well as immune cells. Angiogenesis increased in GM3S-KO mice. In BAEC, RNA interference of GM3S showed increased cellular invasion and oxidative stress tolerance through activation of ERK. In the breast cancer model, GM3-KO mice showed an increase in tumor growth and angiogenesis. These results suggest that the endothelial ganglioside GM3 regulates tumor angiogenesis by suppressing cellular invasion and oxidative stress tolerance in endothelial cells.

Abstract
PURPOSE Taxane-associated acute pain syndrome (T-APS) reportedly occurs in approximately 70% of patients undergoing therapy. We have previously reported that additional dexamethasone (DEX) administration attenuates T-APS. The aim of this study was to reveal risk factor(s) associated with the incidence of T-APS under prophylactic DEX administration. METHODS In total, 143 patients with breast cancer who received docetaxel (75 mg/m2) or paclitaxel (175 mg/m2)-containing treatment regimens were enrolled. DEX (4-8 mg) was orally administered on days 2-4. Risk factors for the incidence of ≥ G2 and all-grade T-APS, as well as T-APS incidence between taxane-containing regimens in the first cycle, were retrospectively evaluated. RESULTS Approximately 90% of the patients received taxanes for adjuvant or neoadjuvant chemotherapy. Overall, 55% of patients administered 4 mg DEX, whereas 45% received 8 mg DEX. Pegfilgrastim was administered in 27% of patients. Incidence of ≥ G2 and all-grade T-APS was 23.8%, and 69.2%, respectively. Univariate and multivariate analyses revealed that administration of pegfilgrastim is an independent risk factor for the incidence of ≥ G2 and all-grade T-APS; age younger than 55 years is also a risk factor for all-grade T-APS. Moreover, the incidence of ≥ G2 and all-grade T-APS was 45.5% and 81.8% in a paclitaxel regimen, and 22.0% and 68.2% in docetaxel-including regimens, respectively, revealing increased tendency with paclitaxel administration, with no significant differences. CONCLUSION Pegfilgrastim co-administration is an independent risk factor for ≥ G2 and all-grade T-APS, and age younger than 55 years is a risk factor of all-grade T-APS under prophylactic DEX administration.

Abstract
Background:The alternative pathway of complement activation has recently been recognized as a key pathogenic event in antineutrophil cytoplasmic antibody (ANCA)-associated vasculitis (AAV). Some previous studies have reported that low serum complement C3 level in AAV patients is associated with more severe renal disease, worse renal prognosis, or higher mortality. However, the correlation between low serum C3 level and AAV relapse remains unclear.Objectives:To analyze the clinical characteristics and outcomes of AAV patients with low serum C3 levels at the time of diagnosis.Methods:We conducted a retrospective observational cohort study including 83 consecutive patients diagnosed with AAV in our hospital from January 1999 to December 2020. Serum C3 levels were measured at diagnosis. AAV included microscopic polyangiitis (MPA), granulomatosis with polyangiitis (GPA), and eosinophilic granulomatosis with polyangiitis (EGPA); patients with ANCA-negative AAV were excluded. Patients were divided into low- and high-C3 groups (C3 < 100 and ≥ 100 mg/dL, respectively). We compared the clinical characteristics, and relapse-free and overall survival rates, of the two groups, and identified predictors of AAV relapse.Results:Of the 83 patients (MPA, n = 61; GPA, n = 18; EGPA, n = 4), 20 (24%) were in the low-C3 group. We found no significant group difference in sex, body mass index, disease type, ANCA subtype, Birmingham Vasculitis Activity Score (BVAS), or treatment. The low-C3 group patients were older (p=0.01), and had a higher Five Factor Score (FFS) (p=0.01) and a lower remission rate (p=0.02), than the high-C3 group. The generalized Wilcoxon test revealed that the relapse-free survival time was significantly shorter in the low-C3 group (29 months; 95% confidence interval [CI]: 15–49) than in the high-C3 group (82 months; 95% CI: 61–NA; p=0.01) (Figure 1A). The overall survival was also shorter in the low-C3 group (83 months; 95% CI: 8-121) than in the high-C3 group (112 months; 95% CI: 77-NA; p=0.03) (Figure 1B). In the Cox proportional hazards model, a low C3 level (< 100 mg/dL) (hazard ratio [HR], 3.01; 95% CI: 1.29–7.04], p=0.01) and GPA (HR, 3.04; 95% CI: 1.32–7.01; p=0.01) were independent predictors of AAV relapse.Figure 1.Kaplan-Meier estimates of the relapse-free (A) and overall (B) survival rates of AAV patients by baseline serum C3 levels. Eight patients who did not show remission were excluded in the relapse-free survival analysis. Black line: high-C3 group (≥ 100 mg/dL); red line: low-C3 group (< 100 mg/dL).Conclusion:AAV patients with low C3 levels at diagnosis were at higher risk of relapse. Larger prospective studies are required to confirm these findings.Disclosure of Interests:None declared

Abstract
Clinical targeted sequencing allows for the selection of patients expected to have a better treatment response, and reveals mechanisms of resistance to molecular targeted therapies based on actionable gene mutations. We underwent comprehensive genomic testing with either our original in-house CLHURC system or with OncoPrime. Samples from 24 patients with estrogen receptor-positive, human epidermal growth factor receptor 2-negative metastatic breast cancer underwent targeted sequencing between 2016 and 2018. Germline and somatic gene alterations and patients' prognosis were retrospectively analyzed according to the response to endocrine therapy. All of the patients had one or more germline and/or somatic gene alterations. Four patients with primary or secondary endocrine-resistant breast cancer harbored germline pathogenic variants of BRCA1, BRCA2, or PTEN. Among somatic gene alterations, TP53, PIK3CA, AKT1, ESR1, and MYC were the most frequently mutated genes. TP53 gene mutation was more frequently observed in patients with primary endocrine resistance compared to those with secondary endocrine resistance or endocrine-responsive breast cancer. Recurrent breast cancer patients carrying TP53-mutant tumors had significantly worse overall survival compared to those with TP53-wild type tumors. Our 160-gene cancer panel will be useful to identify clinically actionable gene alterations in breast cancer in clinical practice.

Abstract
CT-P6 is a biosimilar of trastuzumab and is recommended to be administered for 30-90 min in subsequent maintenance infusions to prevent infusion-related reactions (IRRs). We administered CT-P6 for 30 min as the first injection and as an alternative to reference trastuzumab in the maintenance infusion and evaluated the safety of the administration. A total of 140 patients with breast or gastric cancer, who received a switch from tri-weekly reference trastuzumab to CT-P6 for 30 min in maintenance infusions, were retrospectively evaluated. Premedication was administered prior to an infusion of CT-P6 and a cytotoxic agent. However, premedication was not provided when CT-P6 was co-administered with pertuzumab or administered alone. The primary endpoint was the incidence of IRRs. The secondary endpoint was the incidence of diarrhea and skin toxicity. Ninety-five percent of the patients had breast cancer, and 44.3% had advance-stage cancer. The treatment included CT-P6 alone (17.9%) or with cytotoxic agents (23.6%), antihormonal drugs (25.7%), and pertuzumab (62.9%). Median administration time of trastuzumab at the switch was 13 administrations (range 2-140). Premedication was administered to 20.7% patients. One patient (0.7%) experienced grade 3 IRR. The frequency of diarrhea in the reference trastuzumab group and the CT-P6 group was 7.1 and 6.4%, respectively, and that of skin toxicity was 6.4 and 5.0%, respectively, without differences. In conclusion, we first demonstrated that an initial CT-P6 administration for 30 min during the switch from reference trastuzumab in maintenance infusion is an acceptable administration method.

Abstract
OBJECTIVES Our newly developed brief collaborative care intervention program has been suggested to be effective in reducing breast cancer patients' unmet needs and psychological distress; however, there has been no controlled trial to investigate its effectiveness. The purpose of this study was to examine the effectiveness of the program in relation to patients' perceived needs and other relevant outcomes for patients including quality of life, psychological distress and fear of recurrence (Clinical trial register; UMIN-CTR, Clinical registration number; R5172). METHODS Fifty-nine highly distressed breast cancer patients receiving adjuvant chemotherapy and/or hormonal therapy were randomly assigned either to a treatment as usual group or to a collaborative care intervention, consisting of four sessions that mainly included assessment of the patients' perceived needs, learning skills of problem-solving treatment for coping with unmet needs and psycho-education provided by trained nurses supervised by a psycho-oncologist. RESULTS Although >80% of the eligible patients agreed to participate, and >90% of participants completed the intervention, there were no significant differences with regard to patients' needs, quality of life, psychological distress and fear of recurrence, both at 1 and 3 months after intervention. CONCLUSION Newly developed brief collaborative care intervention program was found to be feasible and acceptable. The trial, however, failed to show the effectiveness of the program on patients' relevant subjective outcomes. Further intervention program having both brevity and sufficient intensity should be developed in future studies.

Abstract
Disease sites of female genital tract cancers of BRCA1/2-associated hereditary breast and ovarian cancer (HBOC) are less understood than non-hereditary cancers. We aimed to elucidate the disease site distribution of genital cancers in women with the germline BRCA1 and BRCA2 pathogenic variants (BRCA1+ and BRCA2+) of HBOC. For the primary disease site, the proportion of fallopian tube and peritoneal cancer was significantly higher in BRCA2+ (40.5%) compared with BRCA1+ (15.4%) and BRCA− (no pathogenic variant, 12.8%). For the metastatic site, the proportion of peritoneal dissemination was significantly higher in BRCA1+ (71.9%) than BRCA− (55.1%) and not different from BRCA2+ (71.4%). With one of the most extensive patients, this study supported the previous reports showing that the pathogenic variants of BRCA1/2 were involved in the female genitalia’s disease sites.

Abstract
BACKGROUND To establish an individualized surgical strategy for lymphadenectomy in ovarian cancer patients with the germline BRCA1 and BRCA2 pathogenic variants (BRCA1+ and BRCA2+), we investigated the clinicopathological characteristics that are involved in the increased risk of lymph node metastasis. METHODS We retrospectively reviewed the data of Japanese women registered in the database of the Japanese Hereditary Breast and Ovarian Cancer Consortium, who underwent BRCA1 and BRCA2 genetic testing. RESULTS We evaluated the predictors of lymph node metastasis in all patients with the information of age at the diagnosis, disease site, histological subtype, 2014 FIGO stage, personal breast cancer history and family history; 233, 153 and 32 patients in the BRCA- (no pathogenic variant), BRCA1+ and BRCA2+ groups, respectively. The prevalence of lymph node metastasis was not markedly different between BRCA- (20.0%), BRCA1+ (18.4%) and BRCA2+ (26.2%). Multivariate analysis revealed an absence of a family history of ovarian cancer as an independent predictor for an increased risk of lymph node metastasis in BRCA1+, and the prevalence of lymph node metastasis was 11.7 and 42.0% in the groups with and without a family history of ovarian cancer, respectively. This subgroup without a family history of ovarian cancer did not show any correlation with a particular variant of BRCA1, including two common variants of c.188 T > A and c.2800C > T. CONCLUSIONS This study suggested that certain genetic factors related to the penetrance of hereditary breast and ovarian cancer syndrome altered the frequency of lymph node metastasis in BRCA1+ ovarian cancer, and family history may be useful to personalize the indication of lymphadenectomy.

Abstract
The characteristic adverse events of olaparib, a PARP inhibitor, are nausea, vomiting, and anemia, and interstitial pneumonia is rarely reported. We report a case of interstitial pneumonia following the treatment of a metastatic breast cancer with olaparib. The patient was a 34-year-old woman. In March 2018, she was diagnosed with stage Ⅳ breast cancer(multiple lung metastases). She was treated with epirubicin and cyclophosphamide followed by paclitaxel. In November 2018, brain and spinal cord metastases were detected, and she was treated with radiation. In December 2018, a BRCA1 deleterious mutation was confirmed, and treatment with olaparib was initiated. Six weeks later, olaparib was discontinued due to anemia; it also caused interstitial pneumonia. The interstitial pneumonia resolved following multidisciplinary treatment during hospitalization. Subsequently, she was treated with cyclophosphamide/methotrexate/fluorouracil. It is necessary to consider interstitial pneumonia as an adverse effect of olaparib.

Abstract
Epirubicin-based chemotherapy carries a risk of inducing heart failure, although the frequency is rare. Bevacizumab, an anti-vascular endothelial growth factor monoclonal antibody, has recently been widely used in patients with recurrent breast cancer as a first-line chemotherapeutic agent. Heart failure or arterial thromboembolism has been reported as a rare cardiovascular complication of bevacizumab. We herein report a breast cancer patient with reversible cancer therapeutics-related cardiac dysfunction associated with bevacizumab and epirubicin complicating intracardiac thrombi in the left atrium and left ventricle. This case underscores the importance of tailored medical planning according to the individual status in patients receiving anti-cancer therapies.

Abstract
Background: Tumor infiltrating lymphocytes (TILs) are immune cells that have migrated to the tumor tissue and the local microenvironment. Recently, evidence has emerged the presence of TILs affects the clinical outcomes of breast cancer patients. We hypothesize that immune cell infiltration profile of the primary tumors affects the timing and type of breast cancer recurrence. We evaluated the relationship between the timing and type of cancer recurrence and clinical factors, gene expression profiles, and immune cell infiltration profile utilizing two published large cohorts, TCGA and METABRIC.
Methods: 308 primary BCs in TCGA were analyzed and categorized as: recurrence ≤2 years (Early), between 2-5 years (Mid), recurrence >5 years (Late), and no recurrence >5 years (Survivors). 1,727 primary BCs in METABRIC were analyzed and categorized similarly: Early, Mid, Late, and Survivors, and further subdivided according to the type of recurrence (distant or local recurrence)
Results: We found that Early tumors demonstrated more aggressive clinical characteristics such as larger tumor, more lymph node metastases, higher pathological grades, higher Stages, and negative estrogen and progesterone receptors, compared with Survivors. On the other hand, no clinical characteristics of Late tumors were significantly different from Survivors, which implicate that clinical characteristics cannot distinguish late recurrence from Survivors. Utilizing pre-ranked gene set enrichment analyses, we showed that primary tumors of Survivors were associated with anti-cancer signaling such as interferon-α/-γ response and TNF-α signaling, compared with all recurrence groups. Furthermore, we found that host defense immunity (leukocyte fraction, lymphocyte infiltration, and macrophage fractions) was decreased in Late tumors compared with Survivors. Utilizing the CIBERSORT algorithm, we showed anti-cancer lymphocytes, memory CD4+ T cells and γδT cells, were significantly lower, and pro-cancerous regulatory T cells were significantly higher in Late tumors compared with Survivors. In distant recurrence analysis, we found that anti-cancer M1 macrophages were higher in Early and Mid compared to Survivors. Pro-cancerous regulatory T cells were significantly higher in Mid compared to Survivors. Interestingly, in local recurrence analysis, there was no statistically significant difference between timing of cancer recurrence and Survivors. Cytolytic activity score that assesses immune cell cytolytic activity was significantly lower in Late compared with Survivors, which suggest it to be a prognostic factor for Late recurrence.
Conclusions: We demonstrated that host defense immunity, pro-cancerous immune cells, and immune cell cytolytic activity in primary breast tumors affect the timing and type of breast cancer recurrence.

Abstract
We report the case of a 44-year-old male who underwent mastectomy plus axillary lymph node dissection after neoadjuvant chemotherapy for left breast cancer. During adjuvant therapy, multiple bone metastases and pericardial effusion were detected. Pericardial drainage was mandated for the patient, although no malignant cells were found. Despite the change in treatment, pericardial effusion worsened. Based on clinical findings, the patient was diagnosed with carcinomatous pericarditis and was switched to bevacizumab plus paclitaxel therapy. CT at 5 months showed improved pericardial effusion; treatment is ongoing.

Abstract
Background:Among collagen vascular diseases, rheumatoid arthritis-associated interstitial lung disease (RA-ILD) is the most commonly associated with ILD with acute exacerbation (AE) [1]. One study reported that ILD diagnosis at an older age, the usual interstitial pneumonia (UIP) pattern on high-resolution computed tomography, and methotrexate (MTX) use were associated with AE in patients with RA-ILD [2]. However, because these studies included few patients, the risk factors and prognosis of AE in patients with RA-ILD remain unclear. Therefore, this study examined the characteristics of RA-ILD patients with AE, and the variables associated with mortality due to AE of RA-ILD.Objectives:To investigate the risk factors for AE and mortality of RA-ILD.Methods:We retrospectively collected the clinical data of 165 RA-ILD patients admitted to our hospital between July 2010 and October 2019. We compared clinical characteristics between patients who developed AE (AE group) and those who did not (non-AE group), and identified the variables significantly associated with AE occurrence. We also compared the admission characteristics of those who survived (survivor group) and those who died (non-survivor group) after admission for AE. AE was defined using previously proposed criteria [3], which were modified slightly for application to RA-ILD.Results:The mean patient age was 73.6 ± 9.7 years and 97 (71.9%) patients were female. Thirty (22.2%) patients developed AE, of whom thirteen (43.3%) died (mean follow-up, 64.9 months). In univariate analyses UIP pattern and MTX were not associated with AE. However, in multivariate analyses, UIP pattern was associated with AE (OR 2.68, 95% CI 1.10–6.52,p=0.03). Median age (70vs. 80 years,p=0.003), non-use of MTX (70.6%vs. 23.1%,p=0.025), and C reactive protein level (median 9.38vs. 18.12 mg/dL,p=0.02) on admission were significantly higher in patients who died of AE. In the Cox proportional hazard model, UIP pattern (HR 4.67, 95% CI 1.02–21.5,p=0.048) and non-use of MTX (HR 0.16, 95% CI 0.04–0.72,p=0.016) were associated with death.Conclusion:Our data suggest that the UIP pattern is related to AE, and non-use of MTX and UIP pattern are related to death due to AE of RA-ILD.References:[1] Suda T, Kaida Y, Nakamura Y et al.

Abstract
BACKGROUND/AIM In estrogen receptor (ER)-positive, human epidermal growth factor receptor 2 (HER2)-negative breast cancer, standard chemotherapies as well as adjuvant endocrine therapy might not be enough for prevention of early relapse. MATERIALS AND METHODS We focused on ER-positive, HER2 immunohistochemistry (IHC) 0 or 1+ breast cancer, and retrospectively examined HER2 gene amplification and TP53 mutation in breast cancer tissues in patients with or without early recurrence. Post-relapse survival in patients with early recurrence was also analyzed by mutation status of HER2 and TP53. RESULTS Surprisingly, amplification of the HER2 gene was found in 15% of patients with early recurrence. None of the patients without relapse had HER2-amplified tumors. Post-relapse survival in patients with HER2 gene amplification and/or TP53 mutation in primary tumors was shorter than that in patients without these mutations, especially among postmenopausal women. CONCLUSION HER2 gene amplification exists in ER-positive, HER2 IHC 0 or 1+ breast cancer in patients who developed early distant metastasis.

Abstract
Abstract
Background: There are now many treatment options for estrogen receptor-positive (ER+) and human epidermal growth factor receptor 2-negative (HER2−) advanced breast cancer (ABC). However, there are few reports indicating the optimal treatment sequence for this disease. Information to predict response to treatment is vital for personalized therapy and determining the most beneficial approach for individual patients. In this study, we attempted to determine predictive factors of response to hormonal therapy and survival outcomes using the large-scale databases constructed in the Safari study (UMIN000015168), a retrospective, multicenter cohort study involving 1,072 Japanese patients receiving fulvestrant 500mg for ER+ ABC. We examined the association between clinicopathological factors and time to failure (TTF) of fulvestrant in Japanese ABC patients.
Methods: Among 1072 patients, 247 patients were selected for this study. Inclusion criteria was as follows: 1) patients treated with either SERM or AI in the adjuvant setting (AS) with known starting and finishing date of the treatment (patients relapsed on adjuvant treatment were excluded), 2) patients treated with SERM, AI and SERD in the metastatic setting (MS) as the first and the second line treatment. Influence of the adjuvant hormonal therapy on the TTF of the first line and the second line treatment and overall survival (OS) was assessed. Cox proportional hazards model was used for this analysis.
Results: Patients treated with SERM in AS had significantly longer TTF of 1st line and 1st+2nd line of hormonal therapy in MS (1st line: HR 1.519, 95% CI 1.04-2.218, p=0.0307, 1st+2nd line: HR 2.372, 95% CI 1.584-3.551, p<0.001) compared with patients treated with AI in AS. Same trend was observed in OS. SERM treated patients in AS had significantly longer OS (OS: HR 2.748, 95% CI 1.574-4.796, p=0.0004) compared with AI treated patients in AS. Since these results described above are the results analyzed by multivariate analysis, they are all statistically significant independent of other factors such as disease free interval in this cohort.
Conclusions: Interestingly, once AI-treated patients in AS have relapsed, their hormone sensitivity is lower and survival outcomes are worse compared with SERM-treated patients in AS in this cohort. Our results have consistency with the results of ABCSG-12 trial showing a pronounced higher risk of death for anastrozole-treated patients (Annals of Oncology 26: 313–320, 2015). Since it is a cohort of selected patients who were successfully treated with fulvestrant, prospective analysis would be therefore warranted.

Abstract
Abstract
Background: To evaluate the survival risk is an important factor to decide or treatment options for recurrent breast cancer patients with estrogen receptor-positive (ER+) and human epidermal growth factor receptor 2 negative (HER2−), though there are not enough supporting reports from large-scale databases. The Safari study (UMIN000015168) is a newly conducted retrospective, multicenter cohort study including 1072 ER+ advanced breast cancer Japanese patients treated with fulvestrant 500 mg mostly as a second or later line hormonal therapy. The follow-up data of Safari study is evaluated to focus on any relationship between clinicopathological factors and post-recurrence survival (PRS) in ER+ HER2− recurrent breast cancer patients. Methods: PRS was defined as the duration from the date of initial treatment for recurrent breast cancer to death. The Cox hazards model was used to evaluate the relationship between the clinical factors and PRS. We also performed multivariate analysis on PRS using factors that showed a statistical difference (p < 0.15) in univariate analysis. Hazard ratios (HRs) with 95% confidence intervals (CIs) and p-values are described. All tests were two-sided and p<0.05 was considered statistically significant. Results: The main analysis was performed for 1031 cases (96.2%). Ninety four patients with HER2+ status and 53 patients with unknown HER2 status were excluded from this analysis. One hundred seventy-four cases with de novo metastatic or unresectable locally advanced disease were also excluded. Seven hundred ten patients were eligible for the PRS analysis. Median PRS was 7.0 years (95% CI: 6.4-7.6 years). In univariate analysis, the following factors were defined as associated with significantly longer PRS; younger age, earlier treatment line, longer the time from recurrent diagnosis to fulvestrant use, lower nuclear or histological grade (G1/G2/G3), no central nerve metastasis, chemotherapy as initial palliative systemic therapy, longer time to initial palliative chemotherapy, no prior perioperative chemotherapy, no prior perioperative hormonal therapy, and longer period after perioperative hormonal therapy to the diagnosis of recurrence. Recurrence cases after over 1-year perioperative hormonal therapy had better PRS than those after less than 1-year therapy. In multivariate analysis, the following factors were identified to be correlated with longer PRS (median 7.0 years); younger age (< 65 years; p = 0.0002), longer time (≥ 3 years) from recurrent breast cancer diagnosis to fulvestrant treatment (p< 0.001), low nuclear or histological grade (1/3; p< 0.001), chemotherapy as an initial palliative systemic treatment (p = 0.01), longer time to initial palliative chemotherapy (p< 0.0001), and no perioperative chemotherapy (p = 0.02). Kaplan-Meier curve showed that a longer time (≥ 1 year) to subsequent chemotherapy correlated positively with prolonged PRS (median PRS: 10.7 years, 95% CI 8.5-12.3 years vs. 6.3 years, 95% CI 5.9-6.8 years; p < 0.0001). Conclusions: In ER+ HER2− recurrent breast cancer patients who received fulvestrant as their initial or second line palliative treatment, the longer duration to initiate a subsequent chemotherapy positively correlated with longer PRS.

Abstract
Transposable element (TE) marker system was developed considering the useful properties of the transposable elements such as their large number in the animal and plant genomes, high rate of insertion polymorphism, and ease of detection. Various methods have been employed for developing a large number of TE markers in several crop plants for genomics studies. Here we describe some of these methods including the recent whole genome search. We also review the application of TE markers in molecular breeding.

Abstract
Polyglutamine diseases are a class of neurodegenerative diseases associated with the accumulation of aggregated mutant proteins. We previously developed a class of degradation-inducing agents targeting the β-sheet-rich structure typical of such aggregates, and we showed that these agents dose-, time-, and proteasome-dependently decrease the intracellular level of mutant huntingtin with an extended polyglutamine tract, which correlates well with the severity of Huntington's disease. Here, we demonstrate that the same agents also deplete other polyglutamine disease-related proteins: mutant ataxin-3 and ataxin-7 in cells from spino-cerebellar ataxia patients, and mutant atrophin-1 in cells from dentatorubral-pallidoluysian atrophy patients. Targeting cross-β-sheet structure could be an effective design strategy to develop therapeutic agents for multiple neurodegenerative diseases.

Abstract
In humans, the adaptive immune system uses the exchange of information between cells to detect and eliminate foreign or damaged cells; however, the removal of unwanted cells does not always require an adaptive immune system1,2. For example, cell selection in Drosophila uses a cell selection mechanism based on 'fitness fingerprints', which allow it to delay ageing3, prevent developmental malformations3,4 and replace old tissues during regeneration5. At the molecular level, these fitness fingerprints consist of combinations of Flower membrane proteins3,4,6. Proteins that indicate reduced fitness are called Flower-Lose, because they are expressed in cells marked to be eliminated6. However, the presence of Flower-Lose isoforms at a cell's membrane does not always lead to elimination, because if neighbouring cells have similar levels of Lose proteins, the cell will not be killed4,6,7. Humans could benefit from the capability to recognize unfit cells, because accumulation of damaged but viable cells during development and ageing causes organ dysfunction and disease8-17. However, in Drosophila this mechanism is hijacked by premalignant cells to gain a competitive growth advantage18. This would be undesirable for humans because it might make tumours more aggressive19-21. It is unknown whether a similar mechanism of cell-fitness comparison is present in humans. Here we show that two human Flower isoforms (hFWE1 and hFWE3) behave as Flower-Lose proteins, whereas the other two isoforms (hFWE2 and hFWE4) behave as Flower-Win proteins. The latter give cells a competitive advantage over cells expressing Lose isoforms, but Lose-expressing cells are not eliminated if their neighbours express similar levels of Lose isoforms; these proteins therefore act as fitness fingerprints. Moreover, human cancer cells show increased Win isoform expression and proliferate in the presence of Lose-expressing stroma, which confers a competitive growth advantage on the cancer cells. Inhibition of the expression of Flower proteins reduces tumour growth and metastasis, and induces sensitivity to chemotherapy. Our results show that ancient mechanisms of cell recognition and selection are active in humans and affect oncogenic growth.

Abstract
Objective The objective of this study was to investigate possible differences in
treatment responses between two categories for the onset of lupus
nephritis. Methods We performed a multicentre, retrospective cohort study of class III–V lupus
nephritis patients diagnosed between 1997 and 2014. The renal responses to
initial induction therapy were compared between patients who developed lupus
nephritis within one year from diagnosis of systemic lupus erythematosus
(early (E-) LN) and the remainder (delayed (D-) LN) using the Kaplan–Meier
method. We determined the predictors of renal response as well as renal
flares and long-term renal outcomes using multivariate Cox regression
analyses. Results A total of 107 E-LN and 70 D-LN patients were followed up for a median of
10.2 years. Log-rank tests showed a lower cumulative incidence of complete
response in D-LN compared with E-LN patients. Multivariate analysis
identified D-LN (hazard ratio (HR) 0.48, 95% confidence interval (CI)
0.33–0.70), nephrotic syndrome at baseline, and a chronicity index greater
than 2 as negative predictors of complete response. D-LN patients were more
likely to experience renal flares. D-LN (HR 2.54, 95% CI 1.10–5.83) and
decreased renal function were significant predictors of chronic kidney
disease at baseline. Conclusion D-LN was a predictor of poorer treatment outcomes, in addition to renal
histology and severity of nephritis at lupus nephritis onset.

Abstract
BACKGROUND Eribulin, an inhibitor of microtubule dynamics, shows antitumor potency against a variety of solid cancers through its antivascular activity and remodeling of tumor vasculature. 18F-Fluoromisonidazole (18F-FMISO) is the most widely used PET probe for imaging tumor hypoxia. In this study, we utilized 18F-FMISO to clarify the effects of eribulin on the tumor hypoxic condition in comparison with histological findings. MATERIAL AND METHODS Mice bearing a human cancer cell xenograft were intraperitoneally administered a single dose of eribulin (0.3 or 1.0 mg/kg) or saline. Three days after the treatment, mice were injected with 18F-FMISO and pimonidazole (hypoxia marker for immunohistochemistry), and intertumoral 18F-FMISO accumulation levels and histological characteristics were determined. PET/CT was performed pre- and post-treatment with eribulin (0.3 mg/kg, i.p.). RESULTS The 18F-FMISO accumulation levels and percent pimonidazole-positive hypoxic area were significantly lower, whereas the number of microvessels was higher in the tumors treated with eribulin. The PET/CT confirmed that 18F-FMISO distribution in the tumor was decreased after the eribulin treatment. CONCLUSIONS Using 18F-FMISO, we demonstrated the elimination of the tumor hypoxic condition by eribulin treatment, concomitantly with the increase in microvessel density. These findings indicate that PET imaging using 18F-FMISO may provide the possibility to detect the early treatment response in clinical patients undergoing eribulin treatment.

Abstract
BACKGROUND We investigated the usefulness of the minimum ADC value of primary breast lesions for predicting axillary lymph node (LN) status in luminal A-like breast cancers with clinically negative nodes in comparison with the mean ADC. METHODS Forty-four luminal A-like breast cancers without axillary LN metastasis at preoperative clinical evaluation, surgically resected with sentinel LN biopsy, were retrospectively studied. Mean and minimum ADC values of each lesion were measured and statistically compared between LN positive (n = 12) and LN negative (n = 32) groups. An ROC curve was drawn to determine the best cutoff value to differentiate LN status. Correlations between mean and minimum ADC values and the number of metastatic axillary LNs were investigated. RESULTS Mean and minimum ADC values of breast lesions with positive LN were significantly lower than those with negative LN (mean 839.9 ± 110.9 vs. 1022.2 ± 250.0 × 10- 6 mm2/s, p = 0.027, minimum 696.7 ± 128.0 vs. 925.0 ± 257.6 × 10- 6 mm2/s, p = 0.004). The sensitivity and NPV using the best cutoff value from ROC using both mean and minimum ADC were 100%. AUC of the minimum ADC (0.784) was higher than that of the mean ADC (0.719). Statistically significant negative correlations were observed between both mean and minimum ADCs and number of positive LNs, with stronger correlation to minimum ADC than mean ADC. CONCLUSIONS The minimum ADC value of primary breast lesions predicts axillary LN metastasis in luminal A-like breast cancer with clinically negative nodes, with high sensitivity and high NPV.

Abstract
Salvage esophagectomy (SALV) is potentially beneficial for patients with residual or relapsed esophageal carcinoma after definitive chemoradiotherapy (dCRT), although preoperatively identifying good candidates for SALV remains difficult. We investigated the prognostic impacts of inflammatory and nutritional status in patients undergoing SALV after dCRT. Forty-seven SALV patients were retrospectively reviewed, of whom 46 (98%) had squamous cell carcinoma and 1 (2%) adenocarcinoma. Possible prognostic factors included patients' demographic data, physical status, blood chemistry profiles, and clinical/pathological tumor features. The Glasgow prognostic score (GPS) was derived from preoperative C-reactive protein (CRP) and albumin values. Thirty (64%), 11 (23%), and 6 (13%) patients were classified into the GPS 0, 1, and 2, respectively, groups. None of the possible prognostic factors showed significant correlations with GPS. Patients with GPS 0 had better outcomes than those with GPS 1 or GPS 2 (Median survivals: 37.8, 15.9, and 5.1 months, respectively, P < 0.001). In the multivariable Cox proportional hazards model, GPS 1 (HR 5.62, 95% CI 1.94-16.4, P = 0.002), GPS 2 (HR 9.10, 95% CI 2.60-31.8, P < 0.001), R1/2 resection (HR 16.3, 95% CI 3.62-86.7, P < 0.001) and incomplete response to dCRT (HR 3.53, 95% CI 1.12-12.5, P = 0.03) were all independent risk factors for a poor outcome. Preoperative GPS is potentially useful for predicting outcomes in esophageal cancer patients undergoing SALV.

Abstract
Background Neoadjuvant endocrine therapy (NET) can improve surgical outcomes in postmenopausal patients with hormone receptor-positive breast cancer. The Ki67 labelling index after NET has a better prognostic power than that at baseline. However, it remains unknown whether a multigene assay with post-treatment samples could predict the prognosis better than that with pretreatment samples. Methods The prognostic value of the multigene assay Oncotype DX Recurrence Score (RS) was investigated using pretreatment and post-treatment samples from a multicentre NET trial, JFMC34-0601 (UMIN C000000345), where exemestane was given at 25 mg/day for 24 weeks. Results Both pretreatment and post-treatment RSs were significantly associated with disease-free survival (DFS) (p=0.005 and 0.002, respectively). The combination of pretreatment and post-treatment RSs was also a predictor of DFS (p=0.002) and superior to preoperative endocrine prognostic index (PEPI). Furthermore, combined RS was the only independent prognostic factor in the multivariate analysis among the three RSs (p=0.04). In addition, combined RS could differentiate early recurrence in the high-risk group from mid/late recurrence in the intermediate-risk group, suggesting possible differential treatment strategies based on the risk categories indicated by the combined RS. Conclusions The combination of pretreatment and post-treatment RSs could provide pivotal information for predicting DFS and differentiating early recurrence in the high-risk group from mid/late recurrence in the intermediate-risk group in patients with hormone receptor-positive breast cancer. A larger study is required to validate the results.

Abstract
Background Expression of estrogen receptor α in breast cancer is essential for estrogen-dependent growth and partially determines the breast cancer subtype. In premenopausal women, expression of estrogen-regulated genes in estrogen receptor-positive breast cancer tissues are reportedly influenced by the menstrual cycle. Methods We investigated correlations between serum estradiol (E2; tested on the day of surgery) and expression of estrogen-regulated genes and proliferation genes in strongly estrogen receptor α-positive breast cancer tissues from 91 premenopausal women by quantitative reverse transcription-polymerase chain reaction. We also investigated correlations between serum progesterone levels on the day of surgery and mRNA expression of progesterone-regulated genes and proliferation genes. Results The serum E2 level affected expression of estrogen-regulated genes, including progesterone receptor (P = 0.016, Rs = 0.07) but showed no correlation with expression of genes associated with proliferation. We also observed strong positive correlations between mRNA expression of ESR1 and that of estrogen-regulated genes (P < 0.0001, Rs = 0.329-0.756) and proliferation genes (P < 0.0001, Rs = 0.753-0.843). The serum progesterone level affected expression of RANKL mRNA. However, we observed no correlations between serum progesterone and expression of Wnt-4 or proliferation genes. Conclusions The serum E2 level on the day of surgery influences estrogen-regulated gene expression moderately in patients found to be strongly positive for estrogen receptor α by immunohistochemistry. Changes in serum E2 levels might influence the results of molecular profiling tests in premenopausal women with breast cancer.

Abstract
The value of assessing tumor infiltrating lymphocytes (TILs) in estrogen receptor (ER) positive/human epidermal growth factor receptor type 2 (HER2) negative breast cancer has yet to be determined. In the present study, a total of 184 cases with early distant recurrence detected within 5 years following the primary operation, 134 with late distant recurrence diagnosed following 5 years or longer and 321 controls without recurrence for >10 years following starting the initial treatment for ER-positive/HER2 negative breast cancer, registered in 9 institutions, were analyzed. The distributions of TILs and their clinical relevance were investigated. TIL distributions did not differ significantly among the early, late and no recurrence groups, employing a 30% cut-off point as a dichotomous variable. In those who had received adjuvant chemotherapy as well as endocrine therapy, a trend toward higher TIL proportions was detected when the early recurrence group was compared with the no recurrence group employing the 30% cut-off point (P=0.064). The TIL distributions were significantly associated with nodal metastasis (P=0.004), ER status (P=0.045), progesterone receptor (PgR) status (P=0.002), tumor grade (P=0.021), and the Ki67 labeling index (LI) (P=0.002) in the no recurrence group and with the Ki67 LI in the recurrence groups (P=0.002 in early recurrence group, P=0.023 in late recurrence group). High TIL distributions also predicted shorter survival time following the detection of recurrence (P=0.026). However, these prognostic interactions were not significant in multivariate analysis (P=0.200). The present retrospective study demonstrated no significant interaction between TIL proportions and the timing of recurrence. However, higher TIL proportions were observed in breast cancer patients with aggressive biological phenotypes, which tended to be more responsive to chemotherapy. The clinical relevance of stromal TILs for identifying patients who would likely benefit from additional therapies merits further investigation in a larger patient population.

Abstract
Estrogen receptor (ER)-positive metastatic breast cancers after a period of response to tamoxifen develop resistance, and the disease progresses clinically. Domination of partial agonistic activity of tamoxifen over its antagonist activity has been implicated as one of the mechanisms for acquired tamoxifen resistance. Six patients with ER-positive, human epidermal growth factor receptor 2 (HER2)-negative metastatic breast cancer who were treated with tamoxifen withdrawal were retrospectively reviewed. Three patients were premenopausal and three were postmenopausal at the beginning of this treatment. Three patients had stage IV disease and three had recurrent breast cancers with median disease-free intervals of 153 months. The treatment lines of tamoxifen therapy were first-line in two, second-line in two, and third-line in one patient. One patient had relapsed during adjuvant tamoxifen therapy. The median duration of tamoxifen therapy was 16 months. The metastatic disease sites at the time of tamoxifen withdrawal were lymph nodes in six, bone in three, chest wall in one, lung in two, pleura in one, and liver in one patient. The median duration of tamoxifen withdrawal was 6.5 months (range 5-> 23 months). Five of six patients had clinical benefits with tamoxifen withdrawal: partial response in one, long stable disease (SD) in four, and SD in one patient. Five patients were treated with aromatase inhibitors after tamoxifen withdrawal. Two patients had metastatic lymph nodes examined by multi-gene panel testing, and both of their tumors had the AKT1 E17K somatic mutation. One patient also had a BRCA1 germline mutation. Tamoxifen withdrawal at the time of tumor progression while on treatment might be an important treatment option, especially for women with highly endocrine-responsive disease.
