Clinical significance of tumor cell seeding associated with needle biopsy in patients with breast cancer. Asian J Surg 2023; 46:3700-3704. [PMID: 36732183 DOI: 10.1016/j.asjsur.2023.01.026] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/21/2022] [Revised: 12/17/2022] [Accepted: 01/06/2023] [Indexed: 02/04/2023] Open
Abstract
BACKGROUND/OBJECTIVE The occurrence of iatrogenic tumor cell seeding (seeding) in needle tract scars formed by core needle biopsy (CNB) or vacuum-assisted biopsy (VAB) is well known. Some risk factors for seeding have been reported, but the clinicopathological risk factors and its prognosis have not been fully investigated. We evaluated the clinical features and prognosis of seeding. METHODS We included 4405 patients who had undergone surgery (lumpectomy or mastectomy) with a diagnosis of breast cancer by preoperative CNB or VAB at our hospital between January 2012 and February 2021. Data of patients with confirmed presence of seeding in resected specimens were collected from pathological records. We analyzed the risk factors of seeding using logistic regression analysis and compared the ipsilateral breast tumor recurrence (IBTR) rate between cases based on the presence or absence of seeding in the lumpectomy group. RESULTS Of the 4405 patients, 133 (3.0%) had confirmed seeding. Univariate analysis revealed the association of clinicopathological features of seeding with lower nuclear grade (NG1 vs NG2-3; p = 0.043), lower Ki-67 (<30 vs. ≥30; p = 0.049), estrogen receptor (ER) positivity (positive vs negative; p<0.01), and human epidermal growth factor receptor 2 (HER2) negativity (negative vs positive; p = 0.016). Multivariate analysis showed ER positivity (odds ratio, 5.23; p<0.05) as an independent risk factor of seeding. The IBTR rate was not significantly different between the seeding and non-seeding groups. CONCLUSIONS Seeding was more likely to occur in ER positive, HER2 negative carcinomas with less aggressive features, and may remain subclinical if adequate adjuvant treatments are administered.

Abstract
OBJECTIVES Low-grade and high-grade endometrial stromal sarcomas (LGESS and HGESS) and undifferentiated uterine sarcomas (UUS) are rare tumors whose pathological classification and staging system have changed recently. These tumors are reported to contain fusion genes. We aimed to clarify the genetic background, clinical features, prognostic factors, and optimal therapy of these tumors using a new classification and staging system. METHODS We analyzed the clinical features and prognostic information of 72 patients with LGESS, 25 with HGESS, and 16 with UUS using central pathological review. Estrogen and progesterone receptors (PgRs) were examined by immunohistochemistry. JAZF1-SUZ12 and YWHAE-NUTM2A/B gene fusions were tested using real-time polymerase chain reaction. RESULTS The 5-year overall survival (OS) rates of LGESS, HGESS, and UUS were 94%, 53%, and 25%, respectively. In LGESS, stage IV, incomplete surgery, and absence of PgR were associated with poor OS. The presence of JAZF1-SUZ12 fusion gene was not associated with OS. In HGESS, the relationship between stage and prognosis was unclear. None of the 3 patients with YWHAE-NUTM2A/B fusion gene died during follow-up. Adjuvant chemotherapy was associated with a favorable OS. Incomplete resection of UUS was associated with poor OS; however, residual tumors frequently occurred. Although most patients underwent adjuvant chemotherapy, their prognosis was extremely poor even in stage I disease. CONCLUSIONS Prognosis of LGESS is generally good; however, stage IV, incomplete surgery, and PgR-negative tumors are associated with poor prognosis. Adjuvant chemotherapy may be useful for HGESS. Prognosis of UUS is extremely poor, even with adjuvant chemotherapy.

Abstract
Neurotrophic tyrosine receptor kinase (NTRK) fusions define infantile fibrosarcomas in young children and NTRK-rearranged spindle-cell tumors in older children and adults, which share characteristic spindle-cell histology and CD34 or S100 protein expression. Similar phenotypes were identified in tumors with BRAF, RAF1, or RET fusions, suggesting a unifying concept of "spindle-cell tumors with kinase gene fusions." In this study, we investigated CD30 expression in 38 mesenchymal tumors with kinase gene fusions using immunohistochemistry. CD30 was expressed in 15 of 22 NTRK-rearranged tumors and 12 of 16 tumors with BRAF, RAF1, or RET fusions. In total, CD30 was expressed in 27 of the 38 tumors (71%), with >50% CD30-positive cells in 21 tumors and predominantly moderate or strong staining in 24 tumors. CD34 and S100 protein were also expressed in 71% and 69% of the tumors, respectively. In contrast, CD30 was significantly less frequently expressed in other mesenchymal tumor types that histologically mimic kinase fusion-positive tumors (9 of 150 tumors, 6%), of which none showed >50% or predominantly strong staining. Among these mimicking tumors, malignant peripheral nerve sheath tumors occasionally (30%) expressed CD30, albeit in a weak focal manner in most positive cases. CD30 was also expressed in 3 of 15 separately analyzed ALK- or ROS1-positive inflammatory myofibroblastic tumors. Frequent expression of CD30 enhances the shared phenotype of spindle-cell tumors with NTRK and other kinase gene fusions, and its sensitivity seems similar to that of CD34 and S100 protein. Although moderate sensitivity hampers its use as a screening tool, CD30 expression could be valuable to rapidly identify high-yield candidates for molecular workup, particularly in communities that lack routine genetic analysis and/or for tumors with BRAF, RAF1, or RET fusions.

Abstract
IntroductionTriple-negative breast cancer (TNBC) is negative for hormone receptors and human epidermal growth factor receptor 2 (HER2). In stage I TNBC, adjuvant therapy or follow-up are performed according to risk factors, but clinical trial data is scarce. In recent years, it has been reported that HER2-low cases (1+/2+ and in situ hybridization negative) have different prognoses than HER2-0 cases. However, the risk of recurrence and risk factors in this HER2-low population for stage I TNBC have not yet been investigated.MethodsHerein, out of 174 patients with TNBC who underwent surgery from June 2004 to December 2009 at the National Cancer Center Hospital (Tokyo), we retrospectively examined 42 cases diagnosed as T1N0M0 TNBC after excluding those treated with preoperative chemotherapy.ResultsAll patients were female, the median age was 60.5 years, and 11 cases were HER2-low and 31 cases were HER2-0. The median follow-up period was 121 months. Postoperative adjuvant therapy was administered in 30 patients and recurrence occurred in 8 patients. HER2-low cases showed a significantly shorter disease-free survival (HR: 7.0; 95% CI: 1.2– 40.2; P=0.0016) and a trend towards shorter overall survival (hazard ratio [HR]: 4.2, 95% confidence interval [CI]: 0.58–31.4) compared with that of HER2-0 cases. HER2 was also identified as a factor for poor prognosis from the point- estimated values in univariate and multivariate analyses after confirming that there was no correlation between the other factors.ConclusionFor patients with stage I TNBC, the HER2-low population had a significantly worse prognosis than the HER2-0 population.

Abstract
PURPOSE The impact of progesterone receptor (PR) status on the prognosis of breast cancer after isolated locoregional recurrence (ILRR) remains unclear. This study evaluated the impact of clinicopathologic factors, including PR status of ILRR, on distant metastasis (DM) after ILRR. METHODS We retrospectively identified 306 patients with ILRR diagnosed at the National Cancer Center Hospital between 1993 and 2021 from the database. Cox proportional hazards analysis was performed to examine factors associated with DM after ILRR. We developed a risk prediction model based on the number of detected risk factors and estimated survival curves using the Kaplan-Meier method. RESULTS During a median follow-up time of 4.7 years after ILRR diagnosis, 86 patients developed DM, and 50 died. Multivariate analysis revealed that seven risk factors were associated with poor distant metastasis-free survival (DMFS): estrogen receptor-positive/PR-negative/human epidermal growth factor receptor 2-negative ILRR, short disease-free interval, recurrence site other than ipsilateral breast, no-resection of ILRR tumor, chemotherapy for the primary tumor, nodal stage in the primary tumor, and no endocrine therapy for ILRR. The predictive model classified patients into 4 groups based on the number of risk factors: low-, intermediate-, high-, and the highest-risk groups with 0 to 1, 2, 3 to 4, and 5 to 7 factors, respectively. This revealed significant variation in DMFS among the groups. A higher number of the risk factors was associated with poorer DMFS. CONCLUSION Our prediction model, which considered the ILRR receptor status, may contribute to the development of a treatment strategy for ILRR.

Abstract
Abstract
Background: The prognostic value of stromal tumor-infiltrating lymphocytes (TILs) as a biomarker for triple-negative breast cancer (TNBC) has been extensively demonstrated in patients (pts) receiving (neo)adjuvant systemic therapy. In addition, several small studies suggest that a subset of pts with early-stage TNBC and high TILs have excellent long-term outcomes, even in the absence of systemic therapy [1-3]. However, data on the absolute risk of TNBC recurrence according to TIL levels in the absence of systemic therapy are limited and critical to inform the design of future systemic therapy de-escalation clinical trials.
Methods: We conducted an individual patient data pooled analysis of 12 international cohorts of pts with TNBC treated with locoregional therapy but no systemic therapy. TNBC was defined as tumors with estrogen and progesterone receptor of < 1% and HER2 negative (IHC 0, 1+ or IHC 2+ and FISH negative) per local evaluation. TILs were locally assessed in hematoxylin & eosin-stained slides according to the International Immuno-Oncology Biomarker Working Group guidelines (www.tilsinbreastcancer.org). We used the Kaplan-Meier method to assess survival outcomes according to prespecified TIL thresholds: 30% and 50%. Confidence intervals (CI) for survival probabilities were calculated using a percentile bootstrap method. The primary endpoint was invasive disease-free survival (iDFS, STEEP 2.0 definition). Key secondary outcomes included recurrence-free survival (RFS), distant disease-free survival (DDFS) and overall survival (OS).
Results: 1,835 pts diagnosed with TNBC between 1982 and 2017 who did not receive systemic therapy were included. The median age at diagnosis was 56 (IQR 38-71). Menopausal status was known in 1,184 women, of whom 78% were post-menopausal. The median tumor size was 2.0 cm (IQR 1.2-2.6). Most pts (87%) had no axillary lymph node involvement (N0). Most tumors were invasive ductal carcinoma (74%) and grade 3 (70%). The median level of TILs was 15% (IQR 5-40). The median duration of follow-up was 30.4 years (95% CI 29.9, 31.1). A total of 950 (52%) iDFS, 828 (45%) RFS, 767 (42%) DDFS events, and 604 (33%) deaths were observed. In multivariable analyses, higher TILs were independently associated with improved iDFS, RFS, DDFS, and OS beyond clinicopathological factors (likelihood ratio p< 10e-6). Each 10% increment in stromal TILs was associated with an 8% (95% CI: 6-11), 10% (95% CI: 7-13), and 13% (95% CI: 10-15) reduction in the risk of experiencing an iDFS, RFS or DDFS event, and with a 12% (95% CI: 9-15) reduction in the risk of death. iDFS, RFS, DDFS and OS rates according to different TIL thresholds and nodal status are shown in the Table. Of note, the RFS estimates (which exclude second non-breast primaries and contralateral breast cancers) were consistently higher than the iDFS counterparts (which include both), consistent with a high rate of contralateral breast cancers and second primary tumors in this cohort. Notably, patients with node-negative—and especially stage I—TNBC with high TILs had excellent survival rates at 10-year follow-up.
Conclusion: TILs are highly prognostic in pts with systemically untreated early-stage TNBC. Pts with pN0 (and especially stage I) TNBC with high TILs exhibited very favorable long-term outcomes even in the absence of systemic therapy. These data define the natural history of TIL-rich TNBC pts and are crucial to identifying the optimal patient population for future chemotherapy and immunotherapy de-escalation clinical trials.

Abstract
BACKGROUND Chemotherapy and radiotherapy were postulated to induce an inflamed tumour microenvironment. We aimed to evaluate the effects of adjuvant chemotherapy/radiotherapy on tumour-infiltrating lymphocytes (TILs) and programmed death-ligand 1 (PD-L1) expression in metastatic breast cancer. METHODS We identified paired primary and metastatic tumours in 85 patients with breast cancer. Stromal TILs were assessed according to international guidelines. PD-L1 expression was evaluated using the VENTANA SP142 assay. RESULTS TILs were significantly lower in metastatic tumours than in primary tumours (12.2 vs. 8.3%, p = 0.049). PD-L1 positivity was similar between primary and metastatic tumours (21.2 vs. 14.1%, p = 0.23). TILs were significantly lower in patients who received adjuvant chemotherapy than in those who did not (-9.07 vs. 1.19%, p = 0.01). However, radiotherapy had no significant effect on TILs (p = 0.44). Decreased TILs predicted worse post-recurrence survival (hazard ratio, 2.94; 95% confidence interval [CI]: 1.41-6.13, p = 0.003), while increased TILs was associated with a better prognosis (HR, 0.12; 95% CI: 0.02-0.08, p = 0.04). CONCLUSIONS TILs decreased in metastatic tumours, particularly in patients who relapsed after adjuvant chemotherapy. Changes in TILs from primary to metastatic sites could be a prognostic factor after recurrence.

Abstract
AIM Cardiovascular disease (CVD) is the second largest cause of death in Japanese women. Pregnancy and childbirth are events that put a strain on the cardiovascular system. When postpartum weight retention is insufficient, weight gain due to fat deposition during pregnancy might lead to obesity. Thus, we examined the effects of body mass index (BMI) in middle and older ages and the number of children on CVD and metabolic disorders. METHODS From the Tohoku Medical Megabank database, we used data from 32,000 women aged ≥ 50 years. This database contains obstetrical history, medical history, and laboratory data obtained once from 2013 to 2015. RESULTS The mean age of participants was 64.2 years, and 47.7% of women had two children. Compared with nulliparous women, those who had a higher number of children had higher BMI and systolic blood pressure. The prevalence of CVD was highest in obese class I (30 kg/m2 ≤ BMI) women with three or more children and the prevalence of hypertension was high in pre-obese (25 kg/m2 ≤ BMI <30 kg/m2) and obese class I women with children. Conversely, the prevalence of diabetes and proportion of women whose HbA1c values were >6.5% was highest in obese class I women with no children. CONCLUSION In this study, we found that not only BMI but also the number of children influenced the health status of middle- and older-aged women, suggesting the importance of childbirth history in the health management of women.

Abstract
PURPOSE This study aimed to evaluate the feasibility and safety of laparoscopic resection of abdominal neuroblastoma by comparing operative and long-term oncologic outcomes between open and laparoscopic surgeries. METHODS This single-center retrospective study included patients who underwent laparoscopic tumor resection, between January 2000 and June 2021, with a maximum tumor diameter of ≤ 60 mm and without image-defined risk factors (IDRFs) at surgery. Data from 35 abdominal neuroblastoma resections were reviewed and compared between the laparotomy and laparoscopic groups. RESULTS Nineteen patients underwent laparotomy and 16 had laparoscopic tumor resection. All laparoscopic surgeries achieved complete resection without conversion to open surgery. Median blood loss was significantly lower in the laparoscopic group (0.6 mL/kg) than in the laparotomy group (8.4 mL/kg) (P < 0.0001). There were two locoregional recurrences in the laparoscopic group and two metastatic recurrences in the laparotomy group. Five-year overall survival was 93.8% in both groups. CONCLUSION Laparoscopic resection of abdominal neuroblastomas in children is a feasible and safe procedure for tumors ≤ 60 mm in diameter with no IDRFs at surgery, with long-term outcomes equivalent to laparotomy.

Abstract
PURPOSE Stromal tumor-infiltrating lymphocytes (TILs) are independent prognostic factors in systemically untreated early-stage triple-negative breast cancer (TNBC). Other immune biomarkers including CD8, CD20, programmed cell death-ligand 1 (PD-L1), and tertiary lymphoid structures (TLS) are also reported to be associated with prognosis. However, whether combining other immune biomarkers with TILs would allow for further prognostic stratification is unknown. METHODS We retrospectively analyzed 125 patients with early-stage TNBC not receiving perioperative chemotherapy. Stromal TILs and TLS were evaluated on hematoxylin-eosin slides. PD-L1 expression was evaluated using the SP142 assay. CD8 and CD20 were assessed by immunohistochemistry and counted by digital pathology. RESULTS Immune biomarker levels were positively correlated (p < 0.001). Adding CD8 and PD-L1 to multivariable analysis including clinicopathological factors (stage and histological grade) and TILs significantly improved the prognostic model (likelihood ratio χ2 = 9.24, p = 0.01). In Cox regression analysis, high CD8 was significantly associated with better prognosis [hazard ratio (HR) 0.69, 95% confidence interval (CI) 0.48-0.98, p = 0.04], and PD-L1 positivity was significantly associated with worse prognosis (HR 4.33, 95%CI 1.57-11.99, p = 0.005). Patients with high CD8/PD-L1 (-) tumors had the most favorable prognosis [5 year invasive disease-free survival (iDFS), 100%], while patients with low CD8/PD-L1( +) tumors had the worst prognosis (5 year iDFS, 33.3%). CONCLUSION CD8 and PD-L1 levels add prognostic information beyond TILs for early-stage TNBC not receiving perioperative chemotherapy. CD8-positive T cells and PD-L1 may be useful for prognostic stratification and in designing future clinical trials of TNBC.

This database continues from 1975, created by the Japanese Breast Cancer Society (JBCS). A total of 95,620 breast cancer cases were registered. The demographics, clinical characteristics, pathology, surgical treatment, adjuvant chemotherapy, adjuvant endocrine therapy, and radiation therapy of Japanese breast cancer patients were summarized. We made comparisons with other reports to reveal the characteristics of our database. We also described some features in Japanese breast cancer that changed over time. The unique characteristics of breast cancer patients in Japan may provide guidance for future research and improvement in healthcare services.

Abstract
Measuring the time variation of the wavenumber spectrum of turbulence is important for understanding the characteristics of high-temperature plasmas, and the application of a Doppler reflectometer with simultaneous multi-frequency sources is expected. To implement this diagnostic in future fusion devices, the use of a phased array antenna (PAA) that can scan microwave beams without moving antennas is recommended. Since the frequency-scanning waveguide leaky-wave antenna-type PAA has a complex structure, we have investigated its characteristics by modeling it with 3D metal powder additive manufacturing (AM). First, a single waveguide is fabricated to understand the characteristics of 3D AM techniques, and it is clear that there are differences in performance depending on the direction of manufacture and surface treatment. Then, a PAA is made, and it is confirmed that the beam can be emitted in any direction by frequency scanning. The plasma flow velocity can be measured by applying the 3D manufacturing PAA to plasma measurement.

Abstract
Abstract
Background
Vascular inflammation plays an important role in the development of atherosclerosis. Previously we have shown that a high-fat diet (HFD) increased neutrophil adhesion to the vascular intima in wild-type (wt) mice (Osaka M. Sci Rep. 2016). However, the involvement of neutrophils in atherosclerosis-related vascular inflammation is not well known.
Purpose
This study examined that neutrophil extracellular trap (NETs) or the hypercitrullination of histone H3 in neutrophils enhances neutrophil adhesion to atheroprone-arteries in LDL receptor null (LDLR−/−) mice.
Methods
We observed leukocyte adhesion in the femoral artery of LDLR−/− mice fed normal chow (NC) or HFD, and determined leukocyte subtype that adhered on vascular endothelium under neutrophil or monocyte depletion using intravital microscopy. Importantly, neutrophil adhesion was examined under the administration of TDFA which inhibits NETs and citrullination of histone H3, in LDLR−/− mice fed HFD. Furthermore, immunohistochemistry for citrullinated histone H3 in peripheral neutrophils of mice was examined. Comprehensive cytokine/chemokine analysis for a plasma of mice was performed to determine the factors citrullinating histone H3 in LDLR−/− mice. Moreover, these mice were treated with a novel specific PPARα agonist, to reduce the elevation of plasma triglyceride levels.
Results
Leukocyte adhesion in LDLR−/− mice fed HFD significantly increased compared to NC. More interestingly, it significantly enhanced compared to wt mice fed HFD. Furthermore, neutrophil depletion rather than monocyte depletion diminished leukocyte adhesion, suggesting that the leukocyte subtype that adhered in LDLR−/− mice fed HFD was neutrophil. Neutrophil adhesion in these mice significantly was reduced by the administration of TDFA, suggesting a pivotal role for histone H3 citrullination in neutrophil adhesion. Moreover, citrullination of histone H3 in neutrophils from LDLR−/− mice fed HFD but not from those without HFD was significantly enhanced. In addition, comprehensive cytokine/chemokine analysis revealed an increase of CXCL1 in plasma of LDLR−/− mice fed HFD. CXCL1 enhanced neutrophil adhesion to HUVECs, and the adhesion significantly decreased by the treatment of TDFA to neutrophil in vitro non-static adhesion assay. These results showed that CXCL1 enhanced neutrophil adhesion in LDLR−/− mice fed HFD through citrullination. Furthermore, when these mice were treated with PPARα agonist, observed histone citrullination, as well as neutrophil adhesion, was significantly reduced.
Conclusion
These results suggest that HFD induced histone citrullination in neutrophils in LDLR−/− mice and PPARα agonist plays a role during hypertriglyceridemia-mediated vascular inflammation in atherosclerosis.

Abstract
The effects of ethanol and caffeine exposure on zebrafish, Danio rerio, were investigated using a combination of measurements of behavioral and physiologic responses in a novel tank situation. Ventilation activity as a physiologic measure was measured remotely by monitoring ventilation-related bioelectric signals from freely moving zebrafish in the test tank. The directions of the behavioral responses, except for outer area preference, were substantially the same in both ethanol- and caffeine-treated fish and qualitatively indistinguishable, suggesting that relying solely on behavioral measures may lead to inappropriate interpretation of drug effects when depending on limited behavioral parameters. By incorporating ventilation activity-related physiologic measures into the quantification of drug effects in novel tank tests, more-accurate evaluations of differences in the effects of moderate doses of anxiolytic ethanol and anxiogenic caffeine were possible. Here, we propose that combining physiologic measures such as ventilation rate and its variability with behavioral measures makes it possible to characterize the effects of environmental challenges on zebrafish in a multi-dimensional and more-detailed manner.

Development and validation of a pre- and intra-operative scoring system that distinguishes between non-advanced and advanced axillary lymph node metastasis in breast cancer with positive sentinel lymph nodes: a retrospective study.

[PMID: 36171615 PMCID: PMC9516796 DOI: 10.1186/s12957-022-02779-9] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/11/2022] [Accepted: 09/16/2022] [Indexed: 11/10/2022] Open
Abstract
Background There are currently no scoring-type predictive models using only easily available pre- and intraoperative data developed for assessment of the risk of advanced axillary lymph node metastasis (ALNM) in patients with breast cancer with metastatic sentinel lymph nodes (SLNs). We aimed to develop and validate a scoring system using only pre- and intraoperative data to distinguish between non-advanced (≤ 3 lymph nodes) and advanced (> 3 lymph nodes) ALNM in patients with breast cancer with metastatic SLNs. Methods We retrospectively identified 804 patients with breast cancer (cT1-3cN0) who had metastatic SLNs and had undergone axillary lymph node dissection (ALND). We evaluated the risk factors for advanced ALNM using logistic regression analysis and developed and validated a scoring system for the prediction of ALNM using training (n = 501) and validation (n = 303) cohorts, respectively. The predictive performance was assessed using the receiver operating characteristic (ROC) curve, area under the curve (AUC), and calibration plots. Results Ultrasound findings of multiple suspicious lymph nodes, SLN macrometastasis, the ratio of metastatic SLNs to the total number of SLNs removed, and the number of metastatic SLNs were significant risk factors for advanced ALNM. Clinical tumor size and invasive lobular carcinoma were of borderline significance. The scoring system based on these six variables yielded high AUCs (0.90 [training] and 0.89 [validation]). The calibration plots of frequency compared to the predicted probability showed slopes of 1.00 (training) and 0.85 (validation), with goodness-of-fit for the model. When the cutoff score was set at 4, the negative predictive values (NPVs) of excluding patients with advanced ALNM were 96.8% (training) and 96.9% (validation). The AUC for predicting advanced ALNM using our scoring system was significantly higher than that predicted by a single independent predictor, such as the number of positive SLNs or the proportion of positive SLNs. Similarly, our scoring system also showed good discrimination and calibration ability when the analysis was restricted to patients with one or two SLN metastases. Conclusion Our easy-to-use scoring system can exclude advanced ALNM with high NPVs. It may contribute to reducing the risk of undertreatment with adjuvant therapies in patients with metastatic SLNs, even if ALND is omitted.

Abstract
AMOTL1 is a member of the Motin protein family and localizes to tight junctions and is involved in cell polarity and paracellular permeability. Pathological variants have been reported in three patients from two separate families in recent years. The clinical spectrum includes cleft lip and palate along with a high incidence of congenital cardiac disease and ear malformations. We report a case of AMOTL1 pathogenic variant in a 11-year-old male patient with nonspecific and chronic liver dysfunction accompanied by persistently elevated liver enzymes since early infancy. Liver biopsy at 8 years of age revealed a mildly dilated central vein and sinusoid with no specific etiology. Liver dysfunction is not a known clinical feature of AMOTL1 malfunction. However, given that the protein is known to be involved in angiogenesis, it may be inferred that abnormalities in this process may lead to liver dysfunction. This is the first report of liver dysfunction identified in a patient with AMOTL1 malfunction, which will shed light on other putative functions of the protein.

Abstract
INTRODUCTION AND IMPORTANCE Primary ALK-positive histiocytosis of the breast is rare. Here, we report a case of ALK-positive histiocytosis with multiple unilateral breast lesions. CASE PRESENTATION Our patient was a 38-year-old female with primary ALK-positive histiocytosis of the breast with multiple lesions. There were no lesions in other organs, and the patient was considered surgically resectable and underwent a left total mastectomy and sentinel lymph node biopsy. Histopathologically, there were at least three lesions in the left breast in upper inner quadrant (UIQ), upper quadrant (UQ), and upper outer quadrant (UOQ). All lesions showed spindle-shaped tumor cells that were positive for CD163 and ALK and negative for AE1/AE3. Fluorescence in situ hybridization (FISH) showed ALK and KIF5B rearrangements, suggesting the presence of the KIF5B-ALK fusion gene. In conclusion, this case was confirmed to be ALK-positive histiocytosis with multiple lesions in the unilateral breast. The patient underwent surgery and was discharged without complications. CLINICAL DISCUSSION Reports of ALK-positive histiocytosis are very rare, and reports of primary cases in the breast are even rarer. The basic treatment for ALK-positive histiocytosis is surgical resection; however, ALK inhibitors may be effective in unresectable or disseminated cases. Accurate diagnosis at the time of initial treatment is necessary to expand the treatment options. CONCLUSION This is the first case of ALK-positive histiocytosis with multiple lesions in the unilateral breast.

Abstract
Abstract
Ductal carcinoma in situ (DCIS) is a precursor to invasive breast cancer. The frequency of DCIS is increasing because of routine mammography; however, the biological features and intratumoral heterogeneity of DCIS remain obscure. To address this deficiency, we performed single-cell transcriptomic profiling of DCIS and invasive ductal carcinoma (IDC). DCIS was found to be composed of several transcriptionally distinct subpopulations of cancer cells with specific functions. Several transcripts, including long noncoding RNAs, were highly expressed in IDC compared to DCIS and might be related to the invasive phenotype. Closeness centrality analysis revealed extensive heterogeneity in DCIS, and the prediction model for cell-to-cell interactions implied that the interaction network among luminal cells and immune cells in DCIS was comparable to that in IDC. Additionally, transcriptomic profiling of HER2+ luminal DCIS indicated HER2 genomic amplification at the DCIS stage. These data provide novel insight into the intratumoral heterogeneity and molecular features of DCIS, which exhibit properties similar to IDC.

Abstract
Cowden syndrome is a rare autosomal dominant disorder characterized by multiple hamartomas in various tissues, including the skin, mucous membranes, and gastrointestinal tract. Germline mutations of the PTEN tumor suppressor gene are responsible for Cowden syndrome. Cowden syndrome is associated with an increased risk of breast, thyroid, renal and uterine cancers; however, ovarian cancer rarely develops in women with Cowden syndrome, although somatic PTEN mutation often occurs in some types of ovarian carcinomas. Herein we report the first case of ovarian carcinosarcoma that developed in a woman with Cowden syndrome. A 55-year-old woman with a history of breast cancer, thyroid goiter, and palatal papillomatosis presented with pelvic distention. CT scan revealed a pelvic tumor suggesting ovarian cancer. She underwent a total abdominal hysterectomy, a bilateral salpingo-oophorectomy, and an omentectomy, but the surgical cytoreduction was suboptima( l >2 cm residual disease). Pathological examination showed a mixed tumor composed of high-grade carcinoma and heterologous sarcoma. Immunohistochemically, tumor cells were positive for p53. She was diagnosed with stage ⅢC ovarian carcinosarcoma. Genetic testing detected a PTEN variant, confirming the diagnosis of Cowden syndrome. She received paclitaxel/ carboplatin chemotherapy. However, no response was observed and she died of disease 2 months postoperatively.

Abstract
AIM Postmastectomy radiotherapy (PMRT) is the standard treatment for locally advanced breast cancer. However, the effectiveness of PMRT in patients with pT1-2 and N1 tumours remains controversial. Therefore, this study aimed to determine the prognostic impact of PMRT in patients with breast cancer and with pT1-2 and 1-3 lymph node metastases. METHODS Using data from the Japanese National Clinical Database from 2004 to 2012, we evaluated the association of PMRT with locoregional recurrence (LRR), any recurrence, and mortality. We enrolled patients who had undergone mastectomy and axillary node dissection and were diagnosed with pT1-2 and N1. We compared clinicopathological factors and prognosis between patients who received (PMRT group) and those who did not receive (No-PMRT group) PMRT. RESULTS Among 8914 patients enrolled, 492 patients belonged to the PMRT group and 8422 to the No-PMRT group. The median observation time was 6.3 years. There was no significant difference in the incidences of LRR (4.0% versus 5.0%, P = 0.61), recurrence (13.8% versus 11.8%, P = 0.23) and breast cancer death (6.0% versus 4.3%, P = 0.08) at 5 years between the groups. Multivariable analysis revealed that LRR was significantly associated with tumour size, number of node metastases and triple-negative subtype but not with PMRT. CONCLUSIONS The LRR rate in the No-PMRT group was 5.0% at 5 years among patients with T1-2 and N1. PMRT did not significantly influence LRR in patients with T1-2 and N1. However, PMRT administration should be tailored considering the individual risks of tumour size, 3 node metastases and triple-negative subtype.

Abstract
BackgroundInterstitial lung disease (ILD) is a frequent complication of rheumatoid arthritis (RA). Although methotrexate (MTX) is an anchor drug for RA management, its use may worsen lung disease severity in patients with RA related ILD (RA-ILD). The safety and efficacy of MTX use in RA-ILD treatment have not been elucidated.ObjectivesWe aimed to clarify the clinical characteristics of patients with RA-ILD and the effect of MTX use on joint and lung disease outcomes.MethodsIn this retrospective study, we included patients with RA-ILD who visited our department from 2011 to 2019 and underwent chest computed tomography (CT). RA was diagnosed using the 1987 ACR criteria or the 2010 ACR/EULAR classification criteria. During the abovementioned period, we defined the baseline as the time of the first chest CT scan; moreover, the final observation was defined as the time of the final chest CT scan in patients who underwent CT more than once, or as the final visit in those without a second chest CT scan. We excluded patients whose RA-ILD status could not be fully evaluated using chest CT scans due to other causes, including respiratory infections. Severe infections were defined as infectious events requiring hospitalization.To identify the clinical characteristics of patients with RA-ILD, we compared the features of RA with versus without ILD at baseline. To clarify the effect of MTX use on RA-ILD outcomes, we compared the outcomes of patients with RA-ILD with versus without MTX use. Furthermore, we investigated factors associated with RA disease activity or ILD deterioration using multivariate analyses.ResultsIn this study, we included 452 patients (mean age, 60.2 years; females, 78.5%; mean observational period, 77.5 months), 325 (71.9%) of whom underwent chest CT more than two times.Patients with ILD (ILD; n=90, 19.9%) were older and had a higher RF positivity rate than those without ILD. Moreover, patients with ILD were treated with lower MTX use (20.2% vs. 52.9%, p<0.001; 1.46 vs. 3.53 mg/week, p<0.001) and TNF inhibitors exposure (21.1% vs. 13.1%, p<0.044) than those without ILD, albeit with similar uses of prednisolone and other bDMARDs, including tocilizumab and abatacept. DAS28-CRP was higher in patients with than in those without ILD at baseline (4.60 vs. 3.42, p=0.063) and at the final observation (2.42 vs. 2.09, p=0.025). Linear regression analysis showed that baseline age and ILD were significantly associated with DAS28-CRP at the final observation (β=0.206 and 0.173, respectively). Kaplan Meier analysis revealed that patients with ILD experienced severe infections and respiratory infections more frequently than those without ILD (log-rank test, p<0.001 and p<0.001).Seventeen patients (20.2%) with ILD were treated with MTX. At baseline, these patients had similar ages and RF/ACPA positivity rates, as well as prednisolone and tDMARDs exposures, with higher bDMARD exposure (41.2 vs. 13.4%, p=0.016) compared to that in ILD patients without MTX use. DAS28-CRP was comparable in patients with and without MTX use at baseline, but was lower at the final observation in MTX-treated patients with ILD (1.41 vs. 2.73, p<0.001). Kaplan Meier analyses revealed no differences in the frequencies of severe infections, respiratory infections, or ILD deterioration between patients with and without MTX use. Cox regression analysis demonstrated that the risk factors for ILD deterioration included baseline age (hazard ratio [HR] 1.088; 95% confidence interval [CI] 1.037-1.147), but not MTX use (HR 1.666; 95% CI 0.472-5.876).ConclusionRA-ILD were treated with lower MTX use, which resulted in higher RA disease activity. In contrast, patients with RA-ILD treated with MTX had lower RA disease activity without ILD deterioration. As RA-ILD is undertreated, appropriate MTX use may be required for effective RA-ILD treatmentReferences[1]Arthritis Rheumatol 2021;73:1108-23.Disclosure of InterestsNone declared

Abstract
BackgroundElevated serum IgG4 levels are one of the characteristic findings in immunoglobulin G4 (IgG4)-related disease (IgG4-RD). Serum IgG4 levels have an impact to a certain extent on the diagnosis of IgG4-RD although there are some issues in their sensitivity and specificity. In the reports from Japan, China, USA, and Europe, elevated serum IgG4 levels were reported to be observed in 83-97% of patients with IgG4-RD [1-5]. In the past investigations of hospital patients, some studies reported that 10-15% of hospital patients with elevated serum IgG4 levels had IgG4-RD [6,7]. However, in general adults with no symptom, investigations of prevalence of elevated serum IgG4 levels and/or IgG4-RD have rarely been conducted.ObjectivesThis study aimed to investigate the frequency of serum IgG4 elevation in the general Japanese population and its associated factors using data from resident examinations.MethodsWe measured the serum IgG4 levels in 1,204 residents who underwent a general medical examination in Ishikawa prefecture, Japan. Logistic regression analysis was used to search for factors related to elevated serum IgG4 levels. Secondary examinations were conducted for participants in whom elevation was identified.ResultsThe mean serum IgG4 level was 44 mg/dL, and elevated serum IgG4 levels were observed in 42 patients (3.5%). Univariate logistic regression analyses showed that male sex, older age, lower estimated glomerular filtration rates based on cystatin C (eGFR-CysC), serum high-density lipoprotein cholesterol levels, and higher hemoglobin A1c (HbA1c) levels were associated with elevated serum IgG4 levels. Subgroup analyses in men showed that older age, lower eGFR-CysC levels, and higher serum HbA1c levels were associated with elevated serum IgG4 levels. In contrast, the analyses in women found no significant factors. One of the 10 residents who underwent secondary examinations was diagnosed with possible IgG4-related retroperitoneal fibrosis.ConclusionIn the general population, elevated serum IgG4 levels are more common in elderly men, which is similar to the epidemiological features of IgG4-RD.References[1]Inoue D, et al.
