Abstract
Purpose Results from studies of extended capecitabine after the standard adjuvant chemotherapy in early stage triple-negative breast cancer (TNBC) were inconsistent, and only low-dose capecitabine from the SYSUCC-001 trial improved disease-free survival (DFS). Adjustment of the conventional adjuvant chemotherapy doses affect the prognosis and may affect the efficacy of subsequent treatments. This study investigated whether the survival benefit of the SYSUCC-001 trial was affected by dose adjustment of the standard adjuvant chemotherapy or not. Patients and Methods We reviewed the adjuvant chemotherapy regimens before the extended capecitabine in the SYSUCC-001 trial. Patients were classified into "consistent" (standard acceptable dose) and "inconsistent" (doses lower than acceptable dose) dose based on the minimum acceptable dose range in the landmark clinical trials. Cox proportional hazards model was used to investigate the impact of dose on the survival outcomes. Results All 434 patients in SYSUCC-001 trial were enrolled in this study. Most of patients administered the anthracycline-taxane regimen accounted for 88.94%. Among patients in the "inconsistent" dose, 60.8% and 47% received lower doses of anthracycline and taxane separately. In the observation group, the "inconsistent" dose of anthracycline and taxane did not affect DFS compared with the "consistent" dose. Moreover, in the capecitabine group, the "inconsistent" anthracycline dose did not affect DFS compared with the "consistent" dose. However, patients with "consistent" taxane doses benefited significantly from extended capecitabine (P=0.014). The sufficient dose of adjuvant taxane had a positive effect of extended capecitabine (hazard ratio [HR] 2.04; 95% confidence interval [CI] 1.02 to 4.06). Conclusion This study found the dose reduction of adjuvant taxane might negatively impact the efficacy of capecitabine. Therefore, the reduction of anthracycline dose over paclitaxel should be given priority during conventional adjuvant chemotherapy, if patients need dose reduction and plan for extended capecitabine.

Abstract
Curebest™ 95GC breast (95GC) is a multigene classifier we developed for the prognostic prediction of patients with estrogen receptor (ER)-positive, human epidermal growth factor receptor 2 (HER2)-negative and node-negative (ER+/HER2-/n0) invasive breast cancer treated with adjuvant endocrine therapy alone. The aim of the preset study was to evaluate the clinical utility of 95GC in a multiinstitutional registry study. Patients (n=215) with ER+/HER2-/n0 invasive breast cancer who had undergone the 95GC assay in seven hospitals were consecutively recruited in the registry study at various postoperative times. At recruitment, no patients had disease recurrences and were prospectively followed up for a median of 62 (range, 6-91) postoperative months. Of the 124 patients classified as 95GC low risk, 118 received adjuvant endocrine therapy alone and six received adjuvant chemo-endocrine therapy. Only two patients developed distant recurrences, and the 5-year distant recurrence-free survival (DRFS) was as high as 98.0%. Of the 91 patients classified as 95GC high risk, 81 received adjuvant chemo-endocrine therapy and 10 received adjuvant endocrine therapy alone. A total of four of these patients developed distant recurrences (5-year DRFS=95.5%). Among the 95GC high-risk patients, prognosis was significantly improved for the 81 treated with adjuvant chemo-endocrine therapy compared with for the 77 (historical controls) treated with adjuvant endocrine therapy alone (P=0.0002; hazard ratio, 0.24). Compared with the St. Gallen 2013 guideline, a significant de-escalation from 73.1% (155/212) to 40.6% (86/212) in adjuvant chemotherapy was achieved. The excellent prognosis of patients with ER+/HER2-/n0 invasive breast cancer classified as 95GC low risk could be validated in the present registry study, indicating that 95GC is useful for safe de-escalation of adjuvant chemotherapy in patients with ER+/HER2-/n0 invasive breast cancer.

Abstract
AIM To explore changes in left ventricular (LV) function and the relationship of these changes with myocardial blood flow (MBF) evaluated by 13N-ammonia hybrid positron-emission tomography (PET)/magnetic resonance imaging (MRI) during vasodilator stress in patients with suspected coronary artery disease (CAD). MATERIALS AND METHODS Fifty-two consecutive patients with suspected CAD, who underwent 13N-ammonia PET/MRI, were enrolled. Vasodilator stress was induced by intravenous injection of adenosine. MBF and coronary flow reserve (CFR) were calculated from dynamic acquisition of 13N-ammonia PET. LV function was evaluated by MRI both at rest and during vasodilator stress. An abnormal perfusion on myocardial images was defined as a summed difference score of ≥4. RESULTS MRI showed that the LV end-diastolic volume, LV end-systolic volume, and LV ejection fraction (LVEF) remained unchanged during vasodilator stress in all patients (n=52) as well as in the patients with CFR of <2 (n=27), stress MBF of <1.3 ml/g/min (n=28), abnormal myocardial perfusion (n=30), and more than one diseased vessel (n=46). In only four patients, the LVEF measured by MRI decreased by >5% during vasodilator stress. In these four patients, CFR was lower (1.57 ± 0.12 versus 2.18 ± 0.86, p<0.01) and the number of diseased vessels was higher (2.75 ± 0.50 versus 1.48 ± 0.92, p<0.01) than in patients without post-stress LV dysfunction. CONCLUSION The LV volume and systolic function evaluated by cardiac MRI remained unchanged during vasodilator stress; however, LV dysfunction during vasodilator stress may occur in patients with severe CAD.

Abstract
Abstract
Background: Most patients with metastatic cancer request information regarding their prognosis, most notably when death is clearly approaching. Several clinical indices are used to predict the prognosis of end-stage cancer based on performance status and clinical factors. For example, the Palliative Prognostic Index (PPI) includes a range of scores from 0-15 based on factors that include performance status, oral intake, presence of edema, dyspnea at rest, and delirium. For scores greater than six, survival for an additional three weeks was predicted with a sensitivity of 80% and a specificity of 85%. However, the predictive power of these indices is currently insufficient; the quality of life of end-stage breast cancer patients would be markedly improved with a more accurate prediction model. Breast cancer subtypes based on the hormone receptor (HR) and human epidermal growth factor receptor 2 (HER2) statuses are important prognostic factors with respect to the outcome of initial breast cancer therapy; the subtype defined by these parameters was also identified as an independent prognostic factor for outcomes in cases of metastatic breast cancer. However, the prognostic impact of breast cancer subtype with respect to end-stage disease remains unclear. In this retrospective observational study, we evaluated the relationship between survival time and associated clinicopathological factors, including breast cancer subtype, in order to develop a more accurate prognostic model for end-stage breast cancer patients. Methods: Seventy-three patients with end-stage breast cancer who were admitted to our hospice care unit from January 2014 to December 2018 were enrolled in the study. Patients in this unit were not provided with anticancer therapy but did receive highest-quality supportive care. The primary endpoint was survival time from the admission. Patient information, including age, PPI, disease-free interval (DFI), the number of treatments for the metastatic disease, metastatic site, and breast cancer subtypes were collected from medical records. Breast cancer subtypes included Luminal (Lum), Lum-HER2, HER2, and triple negative (TN) with respect to those that were HR+HER2−, HR+HER2−, HR−HER2+, and HR−HER2−, respectively. The study was approved by the ethical committee of the Oikawa Hospital (OHCT022). Results: The median survival time was 23 days (1-359 days). From the univariate analysis, PPI scores of less than six were associated with significantly shorter survival (14 days vs. 36.5 days, P = 0.001). Patients diagnosed with Lum-HER2 subtype, those who were older and were without liver metastasis, those with a shorter DFI, and those who underwent fewer treatments for metastatic disease showed a tendency toward a favorable prognosis, although these findings did not reach statistical significance. Multivariate logistic regression analysis revealed that a PPI score less than six (P = 0.001), Lum-HER2 subtype (P = 0.003), absence of liver metastasis (P = 0.001), and DFI lower than the median (33 months; P = 0.028) all contributed to longer survival time. Discussion & Conclusion: In addition to the PPI, breast cancer subtype can be used to provide more precise prognoses for end-stage breast cancer patients. Survival of patients diagnosed with the Lum-HER2 subtype was longer than that observed among those with any of the other subtypes who had not undergone any anticancer treatment for metastatic disease; these results suggest that anti-HER2 therapy may be associated with critical immunological modifications. Taken together, our results indicate that breast cancer subtype should be included to provide a more accurate prognostic model for end-stage breast cancer patients.

Abstract
Survival of patients with breast cancer can be prolonged by treatment with drugs, particularly new molecular-targeted drugs. However, these agents can be expensive and such treatments can be “an economic burden.” In this ongoing trial, we aim to assess the usefulness of ChemoCalc, a software package for calculating drug costs, to help patients understand the financial outlays. In this multicenter, randomized controlled phase 2 trial, 106 patients with advanced breast cancer will be assigned to either the “ChemoCalc” or “Usual Explanation” group. Treatment using ChemoCalc will be discussed with patients in the ChemoCalc group, whereas standard treatments, without using ChemoCalc, will be discussed with patients in the Usual Explanation group. Subsequently, the participants will decide the treatment and complete a five-grade evaluation questionnaire; those in the Usual Explanation group will receive information about ChemoCalc. Investigators will report if patients subsequently decide to change treatments. The primary endpoint will be the scores of two key questions compared between the groups: “Did you understand the cost of treatment in today's discussion?” and “Do you think the cost of treatment is important in choosing a treatment?“. The secondary endpoints will be to compare discrepancies between treatments recommended by physicians and those selected by patients, the time required for discussion, other questionnaire factors, and the relationship between Comprehensive Score for Financial Toxicity tool and treatment selection. This will be the first randomized controlled trial to assess the efficacy of software to help patients understand drug cost estimates and whether it subsequently affects treatment choice. This study will be conducted according to the CONSORT statement. All participants will sign a written consent form. The study protocol was reviewed and approved by the Clinical Research Review Board of Nagasaki University (19070801). The protocol (version 1) was designed and will be conducted in accordance with the Declaration of Helsinki (1964) and the Ethical Guidelines for Medical and Health Research Involving Human Subjects (2017). The findings will be disseminated through scientific and professional conferences, and in peer-reviewed journals.

Abstract
Abstract
Background
Around 10% of patients with acute myocardial infarction (AMI) have chronic total occlusion (CTO) in non-infarct-related vessels, and they are known to be associated with higher mortality in acute phase. However, its impact on long-term prognosis after discharge remains unclear.
Purpose
The purpose of this study was to investigate the influence of presenting CTO lesion on long-term prognosis in patients with AMI.
Method
Consecutive 552 patients with AMI (male 78.3%, age 68±13 years), who had been discharged alive from our hospital, were analyzed. We divided the patients into two groups based on whether they had CTO lesion in a non-infarct-related artery or not: CTO + (n=49) and CTO - (n=503).
Results
Kaplan-Meier analysis (mean follow-up 1,424 days) revealed that all-cause mortality was significantly higher in CTO + group than in CTO - group (Figure, P<0.001). Cox hazard ratio was 2.740, indicating a higher risk of all-cause death in the CTO + group (95% CI 1.606–4.651, P<0.001).
Conclusion
Concurrent coronary CTO lesions in non-culprit arteries were associated with increased long-term mortality in patients with AMI.

Abstract
Abstract
Background
Soluble guanyl cyclase (sGC) is a receptor for nitric oxide (NO) and plays an important role in vascular tonus. sGC stimulant is a therapeutic agent for pulmonary hypertension and an advantage of sGC stimulant over phosphodiesterase (PDE)-5 inhibitors is that sGC stimulant exerts its effect even when NO production is reduced. NO derived from vascular endothelial cells is immediately absorbed by hemoglobin (Hb), which leads to the production of methemoglobin (Met-Hb) when oxidized. Previous report has shown that the therapeutic effect of PDE-5 inhibitors was associated with levels of Met-Hb.
Purpose
In this study, we examined the relationship between the effect of riociguat and levels of Met-Hb in patients with chronic thromboembolic pulmonary hypertension (CTEPH).
Methods
The study population comprised 18 patients with CTEPH. Mean pulmonary artery pressure (mPAP) and pulmonary vascular resistance (PVR) were assessed before and after administration of riociguat, and changes in mPAP and PVR were defined as ΔmPAP and ΔPVR, respectively. Since the level of Met-Hb was obtained as the percentage of Hb (FMet-Hb), the amount of Met-Hb was calculated by following formula:
Met-Hb (mg/dL) = Hb (g/dL) × FMet-Hb (%) × 10.
Results
The amount of Met-Hb value before administration of riociguat was significantly correlated with the degree of improvement in mPAP and PVR after administration of riocigat (R=−0.502, P<0.05 mPAP; R=−0.481, P<0.05 PVR, respectively) as shown in figures.
Conclusion
Our findings suggest that the level of Met-Hb before treatment may predict the therapeutic effect of sGC stimulants in patients with CTEPH.

Abstract
Chemotherapy has played a significant role in breast cancer therapy and dramatically improved the outcome of breast cancer patients. Neoadjuvant chemotherapy (NAC) is defined as chemotherapy conducted before surgery. The rationale for NAC in operable breast cancer is that the benefit of systemic chemotherapy on the long-term prognosis does not change, regardless of whether chemotherapy is conducted before or after surgery. NAC is now widely used for early and advanced breast cancer patients since it has two significant advantages over conventional adjuvant chemotherapy after surgery. One is that the rate of the breast-conserving surgery increase resulted from tumor shrinkage during NAC, which can contribute to a minimal invasion from surgical therapy and good quality of life following therapy. Another is that a response to chemotherapy can be observed in in-vivo setting. Patients who achieve the pathological complete response (pCR) show a favorable prognosis. Thus, the response to NAC can be used as an indicator for personalized medicine. To date, novel agents for NAC have been explored in randomized trials, setting the pCR rate as an endpoint. Also, response- and residual disease-guided therapy have been ready for prime time in daily practice. The author describes the history, current situation, and future direction of NAC for HER2-negative breast cancer in the review article.

Abstract
Abstract
Background: The semi-dry dot-blot (SDB) method is a diagnostic procedure for detecting lymph node (LN) metastases. Metastases are confirmed by the presence of cytokeratin (CK) in the lavage fluid of sectioned LNs using anti-CK antibody on the basis of the theory that epithelial components such as CK are not found in normal LNs. We evaluated novel SDB kits that use a newly developed anti-CK19 antibody and an automatic reader for diagnosing LN metastases in breast cancer patients. Methods: We obtained 127 LNs dissected from 78 breast cancer patients between January 2017 and April 2019 at Nagasaki University Hospital, including 18 dissected axillary LNs and 109 sentinel LNs. These were sliced at 2-mm intervals and washed with phosphate-buffered saline. The suspended cells in the lavage fluid of sliced LNs were centrifuged and lysed to extract protein. The extracted protein was applied to the SDB kit to diagnose LN metastasis using an automatic reader that evaluates absorbance. The washed LNs were blindly diagnosed by pathologists using hematoxylin and eosin (H&E) staining and immunohistochemical (IHC) analysis with anti-CK19 antibody. Diagnoses based on absorbance were also compared with CK19 protein concentration detected by enzyme-linked immunosorbent assay (ELISA).Results: Of the 127 LNs, 52 were assessed as positive and 75 as negative by histological examination with H&E and CK19 IHC. With a borderline CK19 absorbance of seven milli-absorbance (mAbs) for detecting LN metastases excluding isolated tumor cells, the sensitivity, specificity, and accuracy of the SDB kit were 92.3%, 100%, and 96.9%, respectively. In four false-negative cases, there were two CK-19-negative breast cancers and two micrometastases with obvious heat denaturation. With a borderline CK19 absorbance of 50 mAbs for distinguishing macrometastases from micrometastases, the sensitivity, specificity and accuracy of the SDB kit were 81.8%, 97.6%, and 92.1%, respectively. Diagnoses based on the kits and CK19 protein concentration, as determined by ELISA, were well correlated (r=0.90). Furthermore, diagnosis was achieved in approximately 20 min using the kits, at a cost of less than 30 USD. Conclusions: The kits used in our study with an automatic reader were accurate, quick, and cost-effective in diagnosing LN metastases without the loss of LN tissue. However, measures should be taken for clinical use in CK19-negative breast cancer and regarding heat denaturation during surgery.

Abstract
Abstract
Background: Circulating tumor DNA (ctDNA) is shed into the blood stream from cancer cells at primary and metastatic sites. Analysis of ctDNA from plasma reveals genomic profiles of tumors in a non-invasive way, which is promising for overcoming treatment resistance caused by tumor genetic heterogeneity. However, a large amount of DNA from normal cells exists in cell-free DNA (cfDNA), which makes detection of ctDNA difficult without information on genomic aberration at primary and metastatic sites. Recently, the Nick Navin Lab developed an unbiased method for ctDNA analysis, called PEGASUS (Plasma Exome and Genome Analysis by Size-selection and Unbiased Sequencing), that enables whole-genome sequencing of copy number aberrations and somatic mutations from ctDNA. Purpose: This study applied PEGASUS to plasma samples from HER2-positive breast cancer patients, to delineate the detection rate of ctDNA and correlation between ctDNA and clinical course, concentration of cfDNA, and therapeutic outcome. Methods: Nineteen patients with stage I to IIIC of HER2-positive breast cancer who had not received any therapy for breast cancer (Cohort A) and eight HER2-positive patients with a metastatic lesion who were undergoing therapy for breast cancer (Cohort B) were enrolled in the study with written informed consent. In cohort A, plasma samples were collected before and after the therapy. In cohort B, plasma samples were collected serially up to three times. cfDNA from 1 to 5 mL of plasma was extracted by a QIAmp cell-free DNA extraction kit (QIAGEN). Concentration and size distribution of cfDNA was determined by LabChip GX (Perkin Elmer). Following size selection by magnetic beads purification, a multiplex barcoded library was constructed by the KAPA hyper prep Illumina kit (KAPA Biosystems). For genome-wide copy number analysis, the pooled library was sparsely (0.1x) sequenced by the Illumina MiSeq platform. FASTQ files were aligned to the reference human genome (hg19) by bowtie2. The copy number profiles were generated using the median bin count with the Varbin program. Tumor fraction (TFx) was calculated by the ichorCNA program and the threshold of detecting ctDNA was set to 0.03. Results: The mean concentration of cfDNA at the enrollment was 11.1 ng/mL and 25.0 ng/mL in cohort A and cohort B, respectively. The concentration of cfDNA increased during therapy in cohort A, but it correlated to neither TFx nor therapeutic outcome. The mean TFx at the enrollment was 0.019 and 0.036 in cohort A and cohort B, respectively. ctDNA was detected in four cases (21%) and five cases (62.5%) at any timepoint in cohort A and B, respectively. Among the patients in whom ctDNA was detected, two cases showed ERBB2 amplification in both cohort A (10.5%) and cohort B (25%). In an advanced case in cohort A, TFx was 0.065 and ERBB2 amplification was detected. After neoadjuvant chemotherapy with trastuzumab and pertuzumab, pCR was obtained and the ctDNA disappeared. In the case in cohort B, ctDNA and ERBB2 amplification was diminished along with the clinical CR by the therapy. In another case in cohort B, ctDNA and ERBB2 amplification emerged with the progression of disease despite HER2 targeted therapy. Conclusions: ctDNA and ERBB2 amplification was successfully detected among patients with HER2-positive breast cancer using unbiased copy number analysis by PEGASUS.

Abstract
Background: The preoperative diagnosis of thyroid follicular carcinomas (FCs) by fine-needle aspiration cytology is almost impossible. It was previously demonstrated that p53-binding protein 1 (53BP1) expression, based on immunofluorescence (IF), can serve as a valuable biomarker to estimate the malignant potential of various cancers. 53BP1 belongs to a class of DNA damage response molecules that rapidly localize to the site of DNA double-strand breaks, forming nuclear foci (NF). This study aimed to elucidate the utility of 53BP1 NF expression as a biomarker to differentiate follicular tumors (FTs). Methods: Associations between 53BP1 expression based on IF and histological types of FTs were analyzed using 27 follicular adenomas (FAs), 28 minimally invasive FCs, and 14 widely invasive FCs. Furthermore, the study clarified the relationship between 53BP1 NF and copy number aberrations (CNAs) based on array comparative genomic hybridization, a hallmark of genomic instability (GIN). Results: This study demonstrates differences in 53BP1 NF expression between FA and FC. The incidence of 53BP1 at NF significantly increased with FT progression in the following order: normal follicle < FA < minimally invasive FCs < widely invasive FCs. In contrast, no significant differences were observed in CNAs among the FT samples. Furthermore, there was no significant correlation between CNAs and 53BP1 at NF in FTs. Thus, based on a comparison of these two indicators of GIN, 53BP1 NF (by IF) was better able to estimate the malignancy of FTs compared to CNA (by array comparative genomic hybridization). Interestingly, IF revealed a heterogenous distribution of 53BP1 NF, which occurred more frequently in the invasive or subcapsular area than in the center of the tumor, suggesting intratumoral heterogeneity of GIN in FTs. Conclusions: It is proposed that IF analysis of 53BP1 expression could be a novel diagnostic method to estimate the malignant potential of FTs. Because 53BP1 NF reflect DNA double-strand breaks, it is hypothesized that the incidence of 53BP1 at NF can represent the level of GIN in tumor cells. IF analysis of 53BP1 expression will not only be an auxiliary histologic technique to diagnose FTs accurately, but also a novel technique for preoperative diagnosis using fine-needle aspiration cytology.

Abstract
Bi-directional signaling involved in radiation-induced bystander effect (RIBE) between irradiated carcinoma cells and their surrounding non-irradiated normal cells is relevant to radiation cancer therapy. Using the SPICE-NIRS microbeam, we delivered 500 protons to A549-GFP lung carcinoma cells, stably expressing H2B-GFP, which were co-cultured with normal WI-38 cells. The level of γ-H2AX, a marker for DNA double-strand breaks (DSB), was subsequently measured up to 24-h post-irradiation in both targeted and bystander cells. As a result, inhibition of gap junction intercellular communication (GJIC) attenuated DSB repair in targeted A549-GFP cells, and suppressed RIBE in bystander WI-38 cells but not in distant A549-GFP cells. This suggests that GJIC plays a two-way role through propagating DNA damage effect between carcinoma to normal cells and reversing the bystander signaling, also called 'rescue effect' from bystander cells to irradiated cells, to enhance the DSB repair in targeted cells.

Abstract
Regulatory T cells (Tregs) and tumour-associated macrophages (TAMs) contribute to the tumour microenvironment by inhibiting anti-tumour immune responses. This study was performed to investigate the roles of Tregs and TAMs in oral squamous cell carcinoma (OSCC) and oral epithelial precursor lesions (OEPL). The expression of Treg markers CD25 and FoxP3 and TAM markers CD163 and CD204 was investigated in 82 OSCC and 45 OEPL specimens, and their associations with clinicopathological parameters were analyzed. Correlations were found among CD25, FoxP3, CD163, and CD204 levels (P < 0.001), and these targets were up-regulated in OSCC compared to OEPL (P < 0.001). In OSCC, infiltration of Tregs and/or M2 TAMs was associated with sex and clinicopathological features, such as tumour size, nodal metastasis, tissue differentiation, stromal reaction, invasive behaviour, and invasive depth. In OEPL, CD25, FoxP3, CD163, and CD204 immunoreactivities were significantly associated with sex, postoperative recurrence, and cancerization to OSCC. This study is novel in showing that the infiltration of Tregs and M2 TAMs is significantly associated with the progression of premalignant lesions to OSCC. This suggests that these cells represent prognostic biomarkers for premalignant lesion progression and that immunotherapeutic approaches to control Treg/M2 TAM numbers could protect against progression to malignancy.

Abstract
Abstract
Leptomeningeal disease (LMD) involves the dissemination of tumor cells from the primary breast tumors into the membranes surrounding the central nervous system and spinal cords. LMD occurs in about 5% of breast cancer patients and is associated with very poor survival. The genomic evolution of LMD in breast cancer patients has remained difficult to study, in part due to technical challenges in collecting longitudinal biopsy samples from the central nervous system. Liquid biopsies of the cerebral spinal fluid (CSF) may provide a unique opportunity to profile circulating tumor DNA (ctDNA) and has not been compared directly to non-invasive monitoring of ctDNA in blood samples. Furthermore, most non-invasive ctDNA profiling methods are limited to a targeted set of genes and have not allowed unbiased whole-genome profiling. To address these limitations, we developed an unbiased method for ctDNA analysis called PEGASUS (Plasma Exome and Genome Analysis by Size-selection and Unbiased Sequencing) that enables whole-genome sequencing of copy number aberrations and somatic mutations from ctDNA. We applied PEGASUS to sequence matched blood samples and CSF from 10 breast cancer patients with LMD. Quantitation of ctDNA levels showed that ctDNA was detected in CSF samples from 9/10 patients, while blood ctDNA was detected in only 1 LMD patient with extensive metastatic disease. Whole-genome copy number profiling at 220kb resolution and mutational profiling of a 2000 cancer gene panel of the matched CSF and blood samples was performed in 10 LMD patients using PEGASUS. Our data identified aneuploid copy number aberrations and somatic mutations (range: 11-25) in the CSF of 7 patients, including mutations in known driver genes such as BRAF, RB1, TP53 and amplifications of MYC and ERBB2. In contrast the matched blood samples showed only diploid copy number profiles and no detectable somatic mutations in 9/10 LMD patients. In one patient with extensive cranial metastatic disease with matched CSF and blood ctDNA, we found a high concordance in copy number profiles (R= 0.75) and modest concordance of somatic mutations (59.5%), but also additional CNAs and mutations that were specific to the CSF. Collectively, these data show that genomic profiling of ctDNA in CSF is technically feasible for patients with LMD, and provides a major advantage over blood ctDNA which cannot be detected in mostcases.

Abstract
BACKGROUND The semidry dot-blot method is a diagnostic procedure for detecting lymph node (LN) metastases using the presence of cytokeratin (CK) in lavage fluid from sectioned LNs. We evaluated 2 novel kits that use newly developed anti-CK-19 antibodies to diagnose LN metastases in breast cancer. PATIENTS AND METHODS We examined 159 LNs dissected that we sliced at 2-mm intervals and washed with phosphate-buffered saline. The suspended cells in the lavage were centrifuged and lysed to extract protein. This extracted protein was used with a low-power and a high-power kit to diagnose LN metastasis. Diagnoses on the basis of the kits were compared with pathological diagnoses. RESULTS Of the 159 LNs, 68 were assessed as positive and 91 as negative in permanent section examination. Sensitivity, specificity, and accuracy of the low-power kit for detecting LN metastases was 83.8%, 100%, and 93.1%, respectively. Those of the high-power kit were 92.6%, 92.3%, and 92.5%, respectively. Combining the low- and high-power kit results, those for distinguishing macrometastases were 94.5%, 95.2%, and 95.0%, respectively. Diagnosis was achieved in approximately 20 minutes, at a cost of less than $30 USD. CONCLUSION The kits were accurate, fast, and cost-effective in diagnosing LN metastases without the loss of LN tissue.

Abstract
BACKGROUND Squamous cell carcinoma (SCC) of the breast is a rare and generally aggressive disease that accounts for less than 0.1% of all breast carcinomas. Although SCCs have distinct morphological features, their origin and cytogenetic profile are not well understood. METHODS Five patients with SCC were studied. The tumor area that was predominantly composed of SCC components was macrodissected and DNA was extracted. In three cases, an invasive or noninvasive ductal carcinoma of no special type (NST) component was also present. NST-component DNA was also extracted. The tumor DNA was used for array comparative genomic hybridization analysis using a high-density oligonucleotide microarray. The cytogenetic profile of the SCC components was compared with each other and with the paired NST component in three of the five cases. RESULTS The cytogenetic profile of the SCC components indicated large intertumoral heterogeneity. There were between 2 and 160 copy number alterations per case, and no common copy number alterations were identified. The cytogenetic profiles of the paired SCC and NST components were similar but not identical. Although, in one case, a larger number of copy number aberrant regions were detected in the SCC component than the NST component. In this case, all the NST component aberrations were present in the SCC component. This implies that the SCC component originated from the NST component. There were no common SCC component-specific aberrations in the three NST-component cases. CONCLUSION Our results demonstrate the cytogenetic inter- and intratumoral heterogeneity of SCC of the breast. Our comparison of cytogenetic profiles indicated that the SCC component originated from the NST component in one case.

Abstract
Abstract
Background: The semi-dry dot-blot (SDB) method is a diagnostic procedure for detecting lymph node (LN) metastases. Metastases are confirmed by the presence of cytokeratin (CK) in lavage fluid of sectioned LNs that contain anti-pancytokeratin antibody, based on the theory that epithelial components such as CK are not found in normal LNs. We evaluated two novel SDB kits that use the newly developed anti-CK19 antibody for diagnosing LN metastases in breast cancer.
Methods: We obtained 159 LNs dissected from 93 breast cancer patients from July 2013 to December 2015 at Nagasaki University Hospital, including 38 dissected axillary LNs and 121 sentinel LNs, sliced at 2-mm intervals and washed with phosphate-buffered saline. The suspended cells in the lavage fluid of sliced LNs were centrifuged and lysed to extract protein. This extracted protein was used with a low-power and a high-power kit to diagnose LN metastasis. The washed LNs were blindly diagnosed by pathologists using hematoxylin and eosin (H&E) stain. Diagnoses based on the kit were compared with their H&E counterparts.
Results: Of the 159 LNs, 68 were assessed as positive and 91 as negative by permanent pathological examination with H&E. Sensitivity, specificity, and accuracy of the low-power kit for detecting LN metastases was 83.8%, 100%, and 93.1%, respectively. In 11 false-negative cases, there were nine micrometastases, producing a sensitivity of 96.4% for detecting macrometastases. Sensitivity, specificity, and accuracy of the high-power kit for detecting LN metastases was 92.6%, 92.3%, and 92.5%, respectively. Combining the low- and high-power kit results, sensitivity, specificity and accuracy for distinguishing macrometastases from micrometastases was 94.5%, 95.2%, and 95.0%, respectively. Diagnosis was achieved in approximately 20 min using the kits, at a cost of less than 25 USD.
Conclusions: The kits in our study were accurate, quick, and cost-effective in diagnosing LN metastases without the loss of LN tissue. The kits' ability to distinguish macrometastases from micrometastases was excellent, which is important, clinically.

Abstract
Oncocytic follicular adenomas (FAs) of the thyroid are neoplasms of follicular cell origin that are predominantly composed of large polygonal cells with eosinophilic and granular cytoplasm. However, the pathological characteristics of these tumors are largely unexplored. Both the initiation and progression of cancer can be caused by an accumulation of genetic mutations that can induce genomic instability. Thus, the aim of this study was to evaluate the extent of genomic instability in oncocytic FA. As the presence of p53-binding protein 1 (53BP1) in nuclear foci has been found to reflect DNA double-strand breaks that are triggered by various stresses, the immunofluorescence expression pattern of 53BP-1 was assessed in oncocytic and conventional FA. The association with the degree of DNA copy number aberration (CNA) was also evaluated using array-based comparative genomic hybridization. Data from this study demonstrated increased 53BP1 expression (i.e., "unstable" expression) in nuclear foci of oncocytic FA and a higher incidence of CNAs compared with conventional FA. There was also a particular focus on the amplification of chromosome 1p36 in oncocytic FA, which includes the locus for Tumor protein 73, a member of the p53 family implicated as a factor in the development of malignancies. Further evaluations revealed that unstable 53BP1 expression had a significant positive correlation with the levels of expression of Tumor protein 73. These data suggest a higher level of genomic instability in oncocytic FA compared with conventional FA, and a possible relationship between oncocytic FA and abnormal amplification of Tumor protein 73.

Abstract
Abstract
Background: The semi-dry dot-blot (SDB) method is a diagnostic procedure for detecting lymph node (LN) metastases. The metastases are visualized by the presence of cytokeratin (CK) with lavage fluid of sectioned LNs by anti-pancytokeratin antibody, based on the theory that epithelial components such as CK are not found in normal LNs. We previously reported 93.3% sensitivity, 96.9% specificity, and 96.6% accuracy for this method in detecting metastasis in sentinel LNs, compared with permanent pathological diagnosis in breast cancer. In this study, we evaluated a novel kit that applies the SDB method using the newly developed anti-CK19 antibody for diagnosing LN metastases in breast cancer.
Methods: We obtained 141 LNs dissected from 81 breast cancer patients from July 2013 to April 2015 at Nagasaki University Hospital and the Japanese Red Cross Nagasaki Genbaku Hospital, including 33 dissected axillary LNs and 108 sentinel LNs, which were sliced at 2-mm intervals and washed with phosphate-buffered saline. The suspended cells in the lavage fluid of sliced LNs were centrifuged to collect the cell pellet and lysed with lysis buffer to extract protein. This extracted protein was used with the kit to diagnose LN metastasis. The washed LNs were blindly diagnosed by pathologists using hematoxylin and eosin (H&E) stain. Diagnoses based on the kit were compared with their H&E counterparts.
Results: Of the 141 LNs, 57 were assessed as positive and 84 as negative by permanent pathological examination with H&E. Use of the kit resulted in correct diagnoses in 46 of the 57 pathologically positive cases and all of pathologically negative cases. Sensitivity, specificity and accuracy of the kit in detecting LN metastases were 80.7% (95% confidence interval [95% CI]: 75.6–80.7%), 100% (95% CI: 96.5–100%), and 92.2% (95% CI: 88.1–92.2%), respectively. In 11 false-negative cases, there were 9 micrometastases; therefore, sensitivity was 95.5% (95% CI: 90.1–95.5%) in cases of macrometastases. Diagnosis was achieved in approximately 20 min using the kit, reducing the diagnostic time by half compared with the original SDB method. The cost of this kit was within 8 USD, and we are currently developing an improved kit for the detection of smaller metastases.
Conclusions: The kit in our study is accurate, quick, and cost-effective in diagnosing LN metastases without the loss of LN tissue. Its sensitivity in detecting macrometastases is excellent, which is important in clinical practice.

Abstract
Abstract
Background: Squamous cell carcinoma (SCC) of the breast is a rare and generally aggressive disease constituting less than 0.1 % of all breast carcinomas. Although they have distinct morphological features, the origin and cytogenetic profiles of SCCs are still not well understood. In this study, five cases of SCC of the breast, three of which had an SCC component and an invasive or noninvasive ductal carcinoma of no special type (NST) component, were analyzed to evaluate their cytogenetic inter- and intra-tumoral heterogeneity.
Methods: Using a pathological database of approximately 3,000 patients with breast cancer, five patients with SCC were identified. Their medical records were retrospectively reviewed to obtain clinicopathological, radiological, therapeutic and prognostic information. The area largely consisting of the SCC component was macro-dissected from five 10 μm-thick sections and tumor DNA was extracted using the QIAmp DNA Mini Kit (Qiagen). Three cases contained a component of invasive or noninvasive ductal carcinoma of NST as well as an SCC component, and tumor DNA from NST components were also extracted as described above. Tumor DNA from each case were used for array comparative genomic hybridization (aCGH) analysis using a high-density oligonucleotide microarray (Agilent® SurePrint G3 8x60k microarray) and the cytogenetic profiles of SCC components were compared with each other and in three of the five cases with their paired NST components.
Results: Sufficient amounts of DNA were obtained for aCGH analysis with an average of 0.78 μg (0.39–1.35 μg). The quality of the aCGH was acceptable, as judged by the mean derivative log ratio spread (DLRSpread) of 0.45 (0.20–0.55), which estimates the log ratio noise by calculating the spread of log ratio differences between consecutive probes along all chromosomes. The cytogenetic profiles of SCC components showed large inter-tumoral heterogeneity with between 2 and 160 copy number alterations per case and no common copy number alterations were found among cases. Meanwhile, cytogenetic profiles were almost identical between paired SCC and NST components,. However, in one case, a large number of copy number aberrant (CNA) regions were detected in the SCC component compared with the NST component and all aberrations in the NST component were also present in the SCC component, which implies that the SCC component originated from the NST component. There were no common SCC-component-specific aberrations in the three cases with NST components.
Conclusion: These results demonstrate the degree of cytogenetic inter- and intra-tumoral heterogeneity in SCC of the breast. The comparison of cytogenetic profiles in one case indicated that the SCC component originated from the NST component.

Abstract
Abstract
Introduction: Sentinel lymph node (SLN) biopsy is a common diagnostic procedure for breast cancer. However, because of a shortage of pathology specialists in Japan and discordance between intra-operative and final pathological diagnoses of SLN metastasis, new diagnostic modalities are desperately required. We previously reported a novel method of detecting metastasis in SLNs by a semi-dry dot-blot (SDB) method with 93.3% sensitivity, 96.9% specificity and 96.6% accuracy. Here, we evaluated the efficacy of the SDB method using novel anti-cytokeratin (CK) 18+19 antibodies to diagnose lymph node metastases in breast cancer.
Materials and methods: We obtained 73 lymph nodes dissected from 43 patients with breast cancer from July 2013 to May 2014 at Nagasaki University Hospital and the Japanese Red Cross Nagasaki Genbaku Hospital, including 55 sentinel lymph nodes and 18 dissected axillary lymph nodes, which were sliced at 2-mm intervals and washed with phosphate-buffered saline. This lavage fluid was used to diagnose lymph node metastasis by the SDB method; whereas the washed lymph nodes were blindly diagnosed by pathologists using with hematoxylin and eosin (H&E) stain. Suspended cells in the lavage fluid were centrifuged; the cell pellet was lysed with lysis buffer to extract protein, which was then challenged and visualized with anti-cytokeratin 18 and 19 antibodies, each at 1μg/ml and 0.1μg/ml to distinguish between micrometastases or isolated tumor cells (ITC) and macrometastases; and with chromogen on a dot-blot membrane. Diagnoses based on the SDB method were compared with their H&E counterparts. When the SDB method and H&E-based examinations did not agree, we examined specimens immunohistochemically with anti-cytokeratin18+19 antibodies.
Results: Of the 73 lymph nodes, 25 were assessed as positive and 48 as negative by the permanent pathological examination with H&E. The SDB method made correct diagnoses in all positive cases and 42 of the 48 pathologically negative cases. We found four micrometastases and one ITC in the positive cases, which were difficult to diagnose as positive at the lower antibody concentration, but were clearly positive at the higher concentration. When the 6 discrepant cases were examined immunohistochemically, we found two cases of ITC and one of micrometastasis. Sensitivity, specificity and accuracy of the SDB method in detecting cancer cells were 100% (95% confidence interval [95% CI]: 100–100%), 93.8% (95% CI: 86–101%) and 95.9% (95% CI: 91–100%), respectively.
Conclusions: The SDB method using anti-CK18+19 antibodies is simple and accurate for diagnosing lymph node metastases; estimating metastatic amount may be possible with different antibody concentrations. We are producing an SDB kit that uses these antibodies.

Abstract
An 81-year-old man was admitted to a primary care hospital due to bloody diarrhea. The findings of abdominal computed tomography indicated ischemic colitis, so conservative therapy was started. On the 4th hospital day, the patient was transferred to our hospital because of renal dysfunction. Physical examination showed clouding of consciousness and abdominal distention. Abdominal computed tomography revealed massive ascites and thickening of the whole colonic wall. With a diagnosis of acute abdomen, an emergent laparotomy was performed. Extended right hemicolectomy was performed because of severe ischemic change and necrosis of the right side of the colon. In the stool culture before the operation, Escherichia coli O157 and verotoxin were found, so this case was diagnosed as hemorrhagic colitis with hemolytic uremic syndrome and acute encephalopathy due to Escherichia coli O157 infection. Postoperatively, the hemolytic uremic syndrome and acute encephalopathy were prolonged. However, with intensive care, the patient recovered and was discharged on the 33rd postoperative day.

Abstract
BACKGROUND Even after needle biopsy, the preoperative differential diagnoses of intracystic tumors of the breast are challenging because of their nonspecific radiological characteristics and subtle cytological and histological appearance. The aim of this study is to investigate a novel diagnostic method, targeting genomic instability (GIN) in intracystic tumors of the breast, using tumor DNA from samples obtained by fine-needle aspiration biopsy (FNAB). METHODS Thirteen consecutive intracystic tumors of the breast, including five cancers and eight benign tumors, were studied. Three FNAB passages per tumor were used for array comparative genomic hybridization (aCGH) analysis to quantify GIN in each tumor. Tumor DNA from the main tumor, taken from formalin-fixed, paraffin-embedded (FFPE) blocks corresponding to FNAB samples, was also analyzed to compare cytogenetic profiles between these sample types. RESULTS After three FNAB passages, an average of 7.09 μg (0.24-25.0 μg) of DNA was obtained. The quality of the DNA and the aCGH data was excellent, as judged by the mean derivative log ratio spread (DLRSpread) of 0.22 (0.15-0.29). The cytogenetic profiles of paired FNAB and main tumor FFPE samples were highly similar, with an average concordance rate of 97.7 % (81.2-100 %). aCGH analysis from FNAB samples showed significantly more GIN in cancers than in benign tumors, with mean frequencies of aberrant chromosomal regions of 17.5 and 0.34 %, respectively (Wilcoxon's rank sum test, P = 0.0016). CONCLUSIONS Our novel diagnostic method, which targets GIN, can clearly distinguish cancers from benign tumors of breast intracystic lesions with minimal invasion, thereby avoiding the need for surgical excisional biopsy.

Abstract
Abstract
Background:
In breast lesions, indication for surgery is usually determined by pathological diagnosis together with radiological findings. However, differential preoperative diagnoses of intracystic papillary carcinomas vs. papillomas are very challenging even after needle biopsy, because of their non-specific radiological characteristics, and modest cytological and histological appearance. Hence, surgical excisional biopsy is recommended in the clinical management of these lesions, especially when associated with risk factors for malignancy, such as age (≥50years) and the presence of microcalcifications. Meanwhile, genomic instability (GIN) is an important hallmark of cancer, which may be useful for distinguishing cancers from benign tumors. Specifically, intracystic papillary carcinoma harbors significant GIN compared with intracystic papilloma.We have recently reported that genome-wide copy number aberrations can easily be detected by array comparative genomic hybridization (aCGH), which can then be used to quantify GIN. The aim of this study is to investigate a novel diagnostic method, targeting GIN in breast intracystic tumors, using tumor DNA from samples obtained by fine-needle aspiration biopsy (FNAB).
Material and Methods:
Thirteen consecutive breast intracystic tumors resected at Nagasaki University Hospital between August 2010 and March 2012, which included five cancers (four invasive carcinomas and one non-invasive carcinoma) and eight benign tumors (five papilloma, two ductal adenoma and one sclerosing papilloma), were studied. FNABs were performed by an experienced surgeon using a 22-gauge aspiration needle, who performed three FNAB passages per tumor. Tumor DNA was extracted using the QIAmp DNA Mini Kit (Qiagen), followed by aCGH analysis using a high-density oligonucleotide microarray (Agilent® SurePrint G3 8×60k microarray). The frequency of aberrant chromosomal regions in the total genome was used as an indicator of GIN. Tumor DNA from the main tumor, taken from FFPE blocks corresponding to FNAB samples, was also analyzed to assess the similarity of cytogenetic profiles.
Results:
After three FNAB passages, sufficient amounts of DNA were obtained with an average of 7.09 μg (0.24-16.1 μg). The quality of the DNA and the aCGH data was excellent, as judged by the mean derivative log ratio spread (DLRSpread) of 0.22 (0.15-0.29), which estimates the log ratio noise by calculating the spread of log ratio differences between consecutive probes along all chromosomes. Further, the cytogenetic profile of paired FNAB and main tumor FFPE samples were highly similar, with an average concordance rate, defined as the ratio of the length of same copy number within pairs, of 97.7% (81.2-100%). aCGH analysis from FNAB samples showed that cancers harbored significantly more GIN than benign tumors, with mean frequencies of aberrant chromosomal regions of 17.5% and 0.34%, respectively (Wilcoxon's rank sum test, P = 0.0016).
Conclusions:
Our novel diagnostic method, which targets genomic instability, can clearly distinguish cancers from benign tumors of breast intracystic lesions with minimum invasion, thereby avoiding the need for surgical excisional biopsy.

Abstract
Abstract
Background: Among women who take 2-5 years of adjuvant endocrine therapy, more than half of all recurrences of hormone receptor (HR) positive breast cancer occur after the first 5 years. Data from large clinical trials including ATLAS, aTTom,MA17 and NSABP B-30 support extending tamoxifen or aromatase inhibitor beyond 5 year for women with HR positive breast cancer. For decision making according to extending endocrine therapy, the information of the risk of late recurrence is quietly important.
Patients and methods: In order to determine ten year disease free survival (DFS) rates, we reviewed medical records and database of patients who were treated at National Kyushu Cancer Center between 1990 and 2001. Among seven hundred fifty seven patients with HR positive breast cancer, 550 received tamoxifen for 2-5 years. Eighty eight patients had recurrence within five years after surgery, and 13 were not followed, with 83.5% of 5-year DFS after surgery. Remaining four hundred twenty six had no recurrence at the time of 5 years after surgery. To evaluate the risk of late recurrence, we analyzed the long-term results in association with clinicopathological factors for these 426 patients.
Results: Four hundred twenty six patients had 87.1% of 10-year DFS rate. According to lymph node metastasis (N), ten year DFS rates were 91.4% for 275 N-negative and 80.0% for 155 N-positive cases (P = 0.0037). As for the number of lymph node metastasis, 10-year DFS rates were 82.5%, 74.2%, and 79.1% for N1-3, N4-9, N>9, respectively. Tumor size was correlated with the prognosis, and 10-year DFS rates were 91.5% for 167 T1 (≤2 cm), 86.9% for T2 (2-5 cm), and 67.9% for T3 (>5cm) (P = 0.0334). There were no significant differences between grade and prognosis, and 10-year DFS rates of grade 1, 2 and 3 were 88.9%, 89.8%, and 96.8%, respectively (p = 0.3914). Considering the age at 5 years after surgery, no significant differences were observed as for late recurrence. Ten-year DFS rates of 96 cases of age under 50, 227 between 50 and 65, 113 over 65 was 89.4%, 85.1%, and 86.0%, respectively. Ten-year DFS rates of N-negative and N-positive were 94.3% and 81.2%, 88.1% and 80.1%, and 90.4% and 76.7% for these age criteria, respectively.
Conclusion: Patients with HR positive breast cancer require optimal information for decision making whether to receive extending endocrine therapy or not. Our data demonstrated the risk of late recurrence in relation to clinic-pathological factors, which may support the consideration about extending endocrine therapy. Relatively high risks of late recurrence with over 10% of 10 year DFS rates are there in cases with N-positive or T2-3 HR positive breast cancer.

Abstract
Abstract
Objective: Post-mastectomy radiotherapy (PMRT) is strongly recommended for breast cancer patients with 1 to 3 axillary lymph node metastasis (N1-3) in NCCN guidelines Version 3.2013 (category 1), whereas the indication of that treatment should be considered individually according to the risk of local recurrence (St Gallen Consensus Meeting 2013). In order to support decision making of PMRT, we evaluated the risk factors of local recurrence after mastectomy.
Patients and methods: We reviewed retrospectively 2422 cases with Stage I – III primary breast cancer receiving surgery at National Kyushu Cancer Center between 2000 and 2009. Seven hundred seventy six of them underwent mastectomy, and 547 of them received no PMRT. We analyzed the risk of local recurrence in relation to clinicopathologial factors, the status of hormone receptor and HER2, especially in cases with N1-3.
Results: Among 547 cases with no PMRT, there were 364 cases with no LN metastasis (N0), 146 N1-3, and 37 N≥4, and 5-year local disease free survival (DFS) rates were 97.0%, 91.2%, and 73.4%, respectively. In N1-3 (146) cases who underwent no post-operative regional radiotherapies, the 5-year DFS in extent of lymph vessel infiltration (ly) were: ly0 was 97.9% (50) and ly1-3 was 87.9% (92) (ly unknown were 4). In the ly0 cases, the 5-year local DFSs were 100% in grade 2 and 85.7% in grade 3; 100% in ER positive and 90.0% in ER negative; 90.9% in HER2 positive and 100% in HER2 negative. Those in the cases of ly1-3 were 94.5% and 73.4%, 88.7% and 76.6%, and 91.0% and 64.3%, respectively.
Conclusion: In patients with N1-3 breast cancer, the risk of local recurrence after mastectomy was significantly related to grade, extent of lymph vessel infiltration, ER and HER2. PMRT could be omitted in case with ly0,additionaly with grade 1-2, ER positive and HER2 negative. The remaining cases have the risk of local recurrence over 10%, if they don't receive PMRT, in which the indication of PMRT should be considered.

Abstract
We developed an easy, quick and cost-effective detection method for lymph node metastasis called the semi-dry dot-blot (SDB) method, which visualizes the presence of cancer cells with washing of sectioned lymph nodes by anti-pancytokeratin antibody, modifying dot-blot technology. We evaluated the validity and efficacy of the SDB method for the diagnosis of lymph node metastasis in a clinical setting (Trial 1). To evaluate the validity of the SDB method in clinical specimens, 180 dissected lymph nodes from 29 cases, including breast, gastric and colorectal cancer, were examined. Each lymph node was sliced at the maximum diameter and the sensitivity, specificity and accuracy of the SDB method were determined and compared with the final pathology report. Metastasis was detected in 32 lymph nodes (17.8%), and the sensitivity, specificity and accuracy of the SDB method were 100, 98.0 and 98.3%, respectively (Trial 2). To evaluate the efficacy of the SDB method in sentinel lymph node (SLN) biopsy, 174 SLNs from 100 cases of clinically node-negative breast cancer were analyzed. Each SLN was longitudinally sliced at 2-mm intervals and the sensitivity, specificity, accuracy and time required for the SDB method were determined and compared with the intraoperative pathology report. Metastasis was detected in 15 SLNs (8.6%), and the sensitivity, specificity, accuracy and mean required time of the SDB method were 93.3, 96.9, 96.6 and 43.3 min, respectively. The SDB method is a novel and reliable modality for the intraoperative diagnosis of SLN metastasis.

Abstract
Abstract
Background: Sentinel lymph node (SLN) biopsy is a common surgical procedure. However, novel diagnostic modalities are required because of a shortage of pathology specialists in Japan and discordance between the intraoperative and final pathological diagnosis of SLN metastasis. Efficient methods that use molecular markers for detecting SLN metastasis, such as one-step nucleic acid amplification, are commercially available, but special equipment (e.g., thermal cycler) is costly and the problem of false-negatives for CK19 non-expressing cells remains unresolved. Recently, we developed an easy, quick and cost-effective method for detection of cancer cells in lymph nodes by applying dot-blot analysis technology, called the “semi-dry dot-blot method (SDB method)”. The SDB method visualizes the presence of cancer cells with washing of sectioned lymph nodes by anti-pancytokeratin antibody (AE1/AE3) and chromogen on a dot-blot membrane. This method can detect 0.01 mg/mL protein extracted from cancer tissue and 20 suspension cells (MCF-7) in approximately 20 minutes. The current study evaluated the efficacy of our SDB method in the diagnosis of SLN metastasis in breast cancer.
Methods: (I) One hundred eighty dissected lymph nodes from 29 cases, including breast, lung, gastric and colorectal cancer, were analyzed. Each lymph node was sliced at the maximum diameter and washed by phosphate-buffered saline (PBS), and this lavage fluid (PBS) was used for diagnosis of LN metastasis by the SDB method, and washed lymph node was sent to pathological section for pathological diagnosis. The sensitivity, specificity and accuracy of the SDB method were determined to compare with the final pathology report.
(II) A multicenter prospective clinical trial was conducted, where 132 SLN samples from 78 cases of clinically node-negative breast cancer were analyzed. Each SLN was sliced at 2-mm intervals and washed by PBS. Lavage fluid of sliced SLNs was used for the diagnosis of SLN metastasis by the SDB method in a blinded manner. The sensitivity, specificity, accuracy and the time required for the SDB method were determined and compared with the intra-operative pathology report.
Results: (I) Lymph node metastasis was detected in 35 lymph nodes (19.4%). Comparison of the results between the final pathology and the SDB method showed complete concordance (accuracy: 100%).
(II) Of the 132 lymph nodes eligible for analysis, 13 (10.0%) were assessed as positive and 114 as negative by the SDB method and intra-operative pathological examination, with an accuracy of 96.2%. All pathologically positive nodes, which included one micro metastasis, were also detected by the SDB method; (sensitivity: 100%). One hundred fourteen of the 119 pathologically negative nodes were assessed as negative with the SDB method (specificity: 95.8%). The mean required times of 16 cases for intra-operative pathological diagnosis and simultaneous SDB method were 43.5 and 42.2 minutes, respectively.
Conclusions: The SDB method is simple, fast, accurate and cost-effective for the intra-operative diagnosis of SLN metastasis. Because there is no loss of lymph node tissue, the SDB method and pathological investigation can be performed simultaneously.

Abstract
Abstract
Background: Sixty-six years after two atomic bombs (A-bombs) explosion on Hiroshima and Nagasaki, the incidence of breast cancer in A-bomb survivors still higher than that in controlled populations. We have reported a higher incidence of HER2 and C-MYC oncogene amplification in breast cancers from A-bomb survivors, which suggested genomic instability (GIN) induced by A-bomb radiation exposure might promote breast carcinogenesis in A-bomb survivors. The purpose of this study was to clarify the effect of A-bomb radiation exposure on GIN in breast cancer using microarray-comparative genomic hybridization (aCGH).
Materials and Methods: DNA was extracted from the paraffin-embedded tissues of invasive ductal cancers from 11 survivors exposed at 1.5km from the hypocenter and 9 calendar year-matched non-exposed patients followed by aCGH analysis using a high-density oligonucleotide microarray (Agilent® SurePrint G3 8×60k microarray). The total length of chromosomal aberrant region was used as an indicator of GIN, and correlation with clinicopathological factors were statistically tested.
Results: The mean of the derivative log ratio spread (DLRSpread), which estimates the log ratio noise by calculating the spread of log ratio differences between consecutive probes along all chromosomes, was 0.60 (range, 0.30 to 1.05). The concordance of aCGH results with FISH results for HER2 gene amplification was 90%. Samples from A-bomb survivors had significantly more copy number aberrations (CNA) than samples from control patients (P= 0.040). Samples with C-MYC gene amplification determined by aCGH analysis tended to harbor more CNA (P= 0.20), and age at the time of diagnosis tended to be inversely associated with the total length of chromosomal aberrant regions (P= 0.13). The multivariate analysis with covariance revealed that the status of A-bomb exposure was the only independent factor which was significantly associated the total length of chromosomal aberrant regions (P= 0.0324).
Conclusions: This study suggested that A-bomb radiation may affect the development of chromosomal aberrant regions including oncogene amplification by inducing GIN and may be associated with a higher histological grade in breast cancer found in A-bomb survivors.

Abstract
Background It has been postulated that ionizing radiation induces breast cancers among atomic bomb (A-bomb) survivors. We have reported a higher incidence of HER2 and C-MYC oncogene amplification in breast cancers from A-bomb survivors. The purpose of this study was to clarify the effect of A-bomb radiation exposure on genomic instability (GIN), which is an important hallmark of carcinogenesis, in archival formalin-fixed paraffin-embedded (FFPE) tissues of breast cancer by using microarray-comparative genomic hybridization (aCGH). Methods Tumor DNA was extracted from FFPE tissues of invasive ductal cancers from 15 survivors who were exposed at 1.5 km or less from the hypocenter and 13 calendar year-matched non-exposed patients followed by aCGH analysis using a high-density oligonucleotide microarray. The total length of copy number aberrations (CNA) was used as an indicator of GIN, and correlation with clinicopathological factors were statistically tested. Results The mean of the derivative log ratio spread (DLRSpread), which estimates the noise by calculating the spread of log ratio differences between consecutive probes for all chromosomes, was 0.54 (range, 0.26 to 1.05). The concordance of results between aCGH and fluorescence in situ hybridization (FISH) for HER2 gene amplification was 88%. The incidence of HER2 amplification and histological grade was significantly higher in the A-bomb survivors than control group (P = 0.04, respectively). The total length of CNA tended to be larger in the A-bomb survivors (P = 0.15). Correlation analysis of CNA and clinicopathological factors revealed that DLRSpread was negatively correlated with that significantly (P = 0.034, r = -0.40). Multivariate analysis with covariance revealed that the exposure to A-bomb was a significant (P = 0.005) independent factor which was associated with larger total length of CNA of breast cancers. Conclusions Thus, archival FFPE tissues from A-bomb survivors are useful for genome-wide aCGH analysis. Our results suggested that A-bomb radiation may affect the increased amount of CNA as a hallmark of GIN and, subsequently, be associated with a higher histologic grade in breast cancer found in A-bomb survivors.

Abstract
Aerosols were continuously collected for 2 or 3 hours during the periods of 4-27 August 1997 and of 23 March-2 April 1998 at a suburb of Sendai City (east 10 km from Sendai), and meteorological data such as wind directions, wind velocities, etc were measured at the same time. The collected aerosol samples were analyzed by the particle-induced X-ray emission (PIXE) method. Fourteen elements (S, Cl, K, Ca, Ti, V, Cr, Mn, Fe, Ni, Cu, Zn, Hg and Pb) were contained in these samples. The elemental concentrations increased in the daytime and decreased at night. It coincided with the time variation of people movement. The concentrations of Mn, Fe, Zn and Pb elements depended strongly on the direction of wind and their distributions for wind directions reflected to the position of aerosol sources. This result suggests that the position of aerosol source can be determined by measuring aerosols and wind directions at the many positions.
