Abstract
We describe a 58-year old female patient with rapid development of arterial and venous thromboembolisms, including deep vein thrombosis (DVT) in the lower limbs, recurrent cerebral infarctions and bilateral pulmonary emboli. Her laboratory data on admission showed positive anticardiolipin antibody of IgG isotype (IgG aCL) and positive anti-β2 glycoprotein-I antibody of IgG isotype (IgG aβ2-GPI), and decreased protein C activity and protein S antigen. Systemic examinations revealed the presence of an ovarian cancer. Surgical resection was attempted, but her cancer infiltrated the pelvic wall and could not be resected. Despite treatment with unfractionated heparin followed by warfarin, she died due to recurrent episodes of cerebral infarction. This case was considered as probable catastrophic antiphospholipid syndrome (CAPS), which might be associated with ovarian cancer. Known as Trousseau's syndrome, arterial and, more commonly, venous thrombosis is a frequent complication of cancer and sometimes a harbinger of occult cancer. Our case indicates that there is an overlap between antiphospholipid syndrome (APS) and Trousseau's syndrome. It is important to bear in mind that a thrombotic event associated with cancer can be the first manifestation of CAPS.

Abstract
Abstract
Background: The outcome of T1N0 breast cancer is relatively good, however, a subpopulation of this stage has a high population of relapse. It is important to clarify the factors associated with the outcome in order to determine the adequate adjuvant systemic therapy for T1N0 breast cancer.
Aims: To investigate the prognosis of pathological T1N0 (pT1N0) breast cancer by receptor (estrogen receptor; ER, progesterone receptor; PgR, human epidermal growth factor receptor 2; HER2) status and adjuvant systemic therapy, and thus to identify the factors associated with the outcome.
Methods: Among 2164 women who underwent surgery for primary breast cancer in our department, 925 had pathological T1N0 tumors (130 T1a, 234 T1b and 561 T1c). The associations between clinicopathological characteristics, adjuvant therapy and relapse-free survival (RFS) were examined
Results: Of 908 patients with known hormone receptor (HR; ER and PgR) and HER2 status, 675, 79, 64 and 90 had HR+/HER2-, HR+/HER2+, HR-/HER2+ and HR-/HER2- (triple negative; TN) tumors, respectively. The prognosis of patients with T1c tumors was significantly poorer than that of the patients with T1a and T1b tumors (5-year DFS of T1a, T1b and T1c: 97.5%, 97.9%, 94.5%, p=0.0201). HR+/HER2- subtype was significantly associated with better prognosis than other subtypes (5-year DFS: 96.9% vs. 93.6%, p=0.0194). Patients younger than 40 year old or older than 74 years old had significantly shorter PFS (p=0.0039). Lymphovessel invasion (ly), high histological grade (HG2, 3) were associated with poor outcome in all cohort (p=0.0026, p=0.0356). In HR-positive tumors, ly, high HG and omission of the adjuvant endocrine therapy were associated with shorter RFS (p=0.0009, p=0.0306 and p=0.0016, respectively). Adjuvant chemotherapy was not associated with RFS regardless of HR and HER2 status. However, in T1c with nuclear grade (NG) 3 tumors, use of the adjuvant chemotherapy was associated better prognosis. The prognosis of patients with HER2+ tumors was not significantly different among patients with or without trastuzumab in this cohort.
Conclusion: In spite of the excellent prognosis of pT1N0 breast cancer, adjuvant endocrine therapy is important for patients with HR+ tumors. However, the use of adjuvant chemotherapy or trastuzumab did not significantly improve the prognosis. Thus, the indication of chemotherapy or anti-HER2 therapy should be determined in consideration of the several prognostic factors for pT1N0 breast cancer.

Abstract
Abstract
BACKGROUND: In neoadjuvant chemotherapy (NAC) for early breast cancer, the pathological response rate in estrogen receptor (ER)-positive tumors has been low in comparison with those of ER-negative tumors. Therefore, surrogate makers other than the pCR rate are needed during NAC for luminal breast cancer. Using MRI, we analyzed the patterns of tumor shrinkage after NAC as a surrogate prognostic factor in low grade luminal breast cancer. METHODS: Of 854 patients who had received NAC in a single institute from Jan. 2000 to Dec. 2009, 183 patients with low grade luminal breast cancer were retrospectively evaluated for this study. They were defined as ER and/or PgR positive in more than 10% of cancer cells and HER2 negative (IHC 0, 1+ or FISH <2.0) with nuclear grade 1 and 2. RESULTS: The median observation period was 67.9 months following surgery, and recurrence was observed in 31 patients (16.9%). The median age was 49 (22-76) years. One hundred eighty patients received anthracycline-containing chemotherapy, and 158 received taxane. There were 16 deaths (8.7%) related to breast cancer. We categorized the patterns of tumor shrinkage by MRI into 6 types: concentric shrinkage (CS), diffuse decrease (DD), reduction to small foci (RSF), decrease of intensity only (DIO), no change (NC), and enlargement (EL). According to our categorization, CS occurred in 97 (53.0%), RSF in 7 (3.8%), DD in 62 (33.9%), DIO in 7 (3.8%), NC in 5 (2.7%), and EL in 5 (2.7%). As expected, there were statistically significant differences in both the median DFS and OS in each pattern of tumor shrinkage (p <0.001 and p=0.001, respectively); in particular, the CS pattern had excellent prognosis. Multivariate analysis demonstrated that concentric shrinkage was the only significant good prognostic factor for OS (p=0.015). CONCLUSIONS: Tumor shrinkage patterns as revealed by MRI could be important surrogate prognostic factors for NAC in early low grade luminal breast cancer.

Abstract
Abstract
Background: Trastuzumab-containing regimens for the adjuvant treatment of human epidermal growth factor receptor 2 (HER2)-positive early breast cancer significantly improved the prognosis. However, most data showing the effects of trastuzumab come from clinical trials.
Aims: To evaluate the efficacy of the adjuvant trastuzumab in the clinical practice, the prognosis of HER2-positive early breast cancer was investigated according to the adjuvant treatment with or without trastuzumab.
Methods: Among 2548 women who underwent surgery for primary breast cancer in our department between 2000 and 2011, 315 patients had HER2-positive tumors. A total of 293 patients aged 75 or younger with invasive HER2-positive breast cancer were included in this study. The associations between clinicopathological characteristics, adjuvant therapy and relapse-free survival (RFS) were examined. The RFS was estimated using the Kaplan-Meier method, and independent predictors were assessed using proportional cox hazard models.
Results: 113 (38.5%) patients ware treated with chemotherapy alone (Cohort A), 100 (34.1%) patients were treated with chemotherapy and trastuzumab (Cohort B) and 80 (27.3%) patients received neither chemotherapy nor trastuzumab (Cohort C). The administration of adjuvant trastuzumab significantly increased in 2007. The prognosis of the patients treated in 2007-2011 was significantly better than that of patients treated in 2000-2006 (p=0.0011). The use of adjuvant trastuzumab was significantly associated with longer RFS (p=0.0286). The improvement of RFS by using trastuzumab was significant in node-positive patients. The patients in Cohort C had mainly node negative and small tumors. RFS of the patients treated of Cohort B was significantly more favorable than that of Cohort A. However, RFS of Cohort C was not statistically different from that of Cohort B, probably due to the early stage of Cohort C. In univariate analysis, larger tumor size (T2, 3), lymph node metastasis, lymphovessel invasion and absence of trastuzumab were related to relapse. In multivariate analysis, factors related to relapse were lymph node metastasis and absence of trastuzumab.

Abstract
Abstract
Background.
The estrogen receptor (ER)/ GATA3/ Forkhead box A1 (FOXA1) network is necessary for the ERα functional signature specific to luminal type breast cancers. High expression of FOXA1 indicates a good prognosis in ER-positive breast cancer. However, little is known about the association between the expression of FOXA1 and GATA3, and the efficacy of neoadjuvant endocrine therapy (NAE). This study investigated their predictive potential for NAE and the changes of their expression after NAE.
Methods.
The expression of ER, progesterone receptor (PgR), Ki67, FOXA1, and GATA3 were analyzed by immunohistochemistry in 66 patients with hormone receptor-positive/ human epidermal growth factor receptor 2 (HER2)-negative breast cancer who had been treated with NAE between March 2003 and December 2012 at Kyushu University Hospital, National Kyushu Cancer Center, and Sagara Hospital. The association between the expression of biological marker and the efficacy of NAE, and their expression changes after NAE were evaluated.
Results.
The median age of the patients was 60 years (range, 30–84 years). Pre- and post-menopausal patients were 24 (36.4%) and 42 (63.6%). Endocrine agents that were administered are as follows: aromatase inhibitors (AIs) for 42 patients (63.6%), luteinizing hormone-releasing hormone (LHRH) agonist plus AI for 10 patients (15.2%), LHRH agonist plus tamoxifen for 13 patients (19.7%). NAE yielded a partial response (PR) in 21 patients (31.8%) and stable disease (SD) in 45 patients (68.2%). Breast conserving surgery was performed in 56 patients (84.8%) and mastectomy was performed in 10 patients (15.2%). Preoperative Endocrine Prognostic Index (PEPI) score was 0 in 10 patients (15.2%) and 1 or greater (score 1 ≤) in 56 patients (84.8%).
Pre-treatment FOXA1 expression was positively correlated with GATA3 (P = 0.0003) and PgR (P = 0.0138). Post-treatment Ki67 expression was significantly lower in tumors, which achieved PR compared with those with SD (P = 0.0007). The expression of PgR, Ki67, and FOXA1 was significantly lower in post-treatment tumors compared with those in pre-treatment samples (p < 0.0001, p < 0.0001 and p < 0.0001, respectively). The expression of PgR, Ki67, and FOXA1 was significantly reduced in both tumors with PR and those with SD (PR: P = 0.0004, P < 0.0001, and P = 0.0417, respectively; SD: P < 0.0001, P = 0.0001, and P < 0.0001, respectively). The expression of PgR, Ki67, and FOXA1 was significantly decreased in post-treatment tumors in both patients with the PEPI score 0 and those with score 1 ≤ (score 0: P = 0.0078, P = 0.0059, and P = 0.0098, respectively; score 1 ≤: P < 0.0001, P < 0.0001, and P = 0.0002, respectively). In tumors with PgR > 20%, the expression of Ki67 and FOXA1 were significantly lower in post-treatment tumors (P < 0.0001 and P < 0.0001, respectively).
Conclusions.
FOXA1 expression correlated with PgR expression, and was reduced significantly after NAE. These results suggest that blocking the effect of estrogen might reduce FOXA1 expression.

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
Background
Fulvestrant 500 mg has demonstrated improved efficacy vs fulvestrant 250 mg (time to progression [TTP]/progression free survival [PFS] and overall survival) in the treatment of postmenopausal women with advanced breast cancer (ABC). Few clinical trials have demonstrated a significant increase in clinical benefit rate (CBR) for one endocrine therapy (ET) over another for the treatment of ABC. This implies that TTP/PFS improvements have been achieved principally by prolonging time to developing acquired resistance. However, it would be beneficial to know whether CBR is also improved, indicating that more patients experience tumor remission. We performed a meta-analysis to determine if there was a difference in CBR between fulvestrant 500 mg and its comparators in randomized clinical trials (RCTs).
Methods
Five RCTs evaluating fulvestrant 500 mg were included: CONFIRM, China CONFIRM, FINDER1 and FINDER2 (vs fulvestrant 250 mg) as second-line ET and FIRST (vs anastrozole) as first-line ET. CBR was calculated as the proportion of patients experiencing a best objective response of stable disease for ≥24 weeks, complete response or partial response. Peto method was used to calculate odds ratios (ORs), 95% confidence intervals (CIs) and p values. Separate fixed effect (FE) models were constructed for first- and second-line data combined, and for second-line only data. For each model Tarone's test for heterogeneity assessed the assumption of constant trial effect.
Results
Unadjusted ORs for CBR from CONFIRM, FINDER1 and FINDER2, adjusted OR for China CONFIRM (as reported in the trial publications), and combined FE models are shown (Table).The OR (95% CI) of the FE model for all trials indicated that CBR was higher with fulvestrant 500 mg than with comparator treatments (OR: 1.34 [1.12-1.61]; FE p=0.001; Tarone's test p=0.91). When assessing second-line ET only, the OR was similar to the overall combined analysis.

Adjusted odds ratio and CI (as reported in the trial publications) are presented for China CONFIRM; unadjusted odds ratios and CIs are used for all other trials. FINDER1 and FINDER2 included fulvestrant 500 mg, 250 mg plus loading dose, and 250 mg treatment arms. Data shown for fulvestrant 500 mg versus 250 mg.
Conclusions
These data suggest that fulvestrant 500 mg is associated with a significant improvement in CBR of approximately 34% compared with comparator ETs (i.e. more tumors are placed into remission). This finding is consistent in both second- and first-line ET settings. We await the results of the Phase 3 FALCON first-line ET RCT to see if it supports this finding of increased CBR with fulvestrant 500 mg.

Abstract
BACKGROUND Pathologic evidence of biliary diseases can be obtained from cytology in addition to endoscopic retrograde cholangiopancreatography (ERCP); however, the diagnostic effectiveness is not satisfactory. STUDY AIM This retrospective, single-center study evaluated the efficacy of various sampling methods for the cytologic diagnosis of bile duct cancer. PATIENTS AND METHODS Biliary samples included bile that was simply aspirated, brush smear, brush-rinsed saline, and post-brushing biliary lavage fluid. A set of samples was compared for cytologic efficacy in 76 patients with surgically proven bile duct cancer and in 50 patients with benign biliary stricture. RESULTS The cytologic sensitivity for diagnosing biliary cancer was 34 % with aspirated bile, 32 % with brush smear, 43 % with brush-rinsed saline, and 70 % with post-brushing biliary lavage fluid, in contrast to the null false-positive result in the benign cases. The sensitivity of cytology was significantly higher with post-brushing lavage fluid than with the other three sampling methods (P < 0.0001), and post-brushing lavage fluid improved the cumulative sensitivity by 24 % (P = 0.002). The sensitivity of biliary cytology was also associated with the amount of aspirated bile (P = 0.01) and with the aspiration site (P = 0.03). The rate of cancer positivity in a cytology set differed according to the tumor macroscopic type (85 % in the protruding type vs. 40 % in the flat type; P = 0.003), and according to the size of the cancer (87 % for tumors ≥ 50 mm vs. 66 % for tumors < 50 mm; P = 0.02). CONCLUSIONS Post-brushing biliary lavage fluid cytology provides superior diagnostic efficacy, and its addition to ERCP procedures is recommended for obtaining cytologic evidence of bile duct cancer.

Abstract
Radiation therapy (RT) is useful for selectively killing cancer cells. However, because high levels of ionizing radiation (IR) are toxic to normal cells, RT cannot be applied repeatedly to cancer patients. Therefore, novel chemicals that enhance the efficacy of chemoradiotherapy (CRT) would be valuable. Here, we report that ELAS1, a peptide corresponding to the protein phosphatase 2A (PP2A) association domain of cyclin G1 (CycG1), can enhance the efficacy of CRT. ELAS1 interacts with the PP2A B'γ-subunit and competitively inhibits association with CycG1, thereby preventing the PP2A holoenzyme from dephosphorylating target proteins, Mdm2 (pT218) and p53 (pS46), following DNA double-strand break (DSB) insults. Doxycycline (Dox)-induced overexpression of Myc-ELAS1 caused γ-irradiation to induce apoptosis in human osteosarcoma (U2OS) cells, at 1/10th the effective dosage of γ-irradiation required for apoptosis in Myc-vector-expressing cells; ELAS1 peptide incorporation into U2OS cells also showed similar apoptotic effects. Moreover, administration of DSB-inducing chemicals, camptothecin (CPT) or irinotecan, to Myc-ELAS1-expressing U2OS cells also induced efficient apoptosis with only 1/100th (CPT) or 1/5th (irinotecan) of the amounts of drugs required for this effect in Myc-vector-expressing cells. Taken together, ELAS1 may be important for the design of ELAS1-mimetic compounds to improve CRT efficacy.

Abstract
BACKGROUND Identification of promising biomarkers that predict the prognosis of patients with breast cancer is needed. In this study, we hypothesised that the expression of the epithelial-mesenchymal transition-related biomarker plastin3 (PLS3) in peripheral blood could be a prognostic factor in breast cancer. METHODS We examined PLS3 expression in breast cancer cell lines with epithelial and mesenchymal traits and in circulating tumour cells (CTCs) obtained from the peripheral blood of breast cancer patients. We investigated PLS3 expression in the peripheral blood of 594 patients with breast cancer to evaluate the clinical significance of PLS3 expression. RESULTS Robust PLS3 expression was observed in different breast cancer cell lines (Hs578t, MCF-7, MDA-MB-468, and MDA-MB-231) as well as in a bone marrow derived cancer cell line (BC-M1). In both the training (n=298) and validation (n=296) sets, PLS3 expression was observed in CTCs of patients with breast cancer. PLS3-positive patients showed significantly poorer overall and disease-free survival than PLS3-negative patients (P=0.0001 and 0.003, respectively). Subset analysis revealed that this prognostic biomarker was relevant in patients with stage I-III cancer, particularly in patients with luminal-type and triple-negative-type tumours. CONCLUSIONS These data demonstrated that PLS3 was expressed in CTCs undergoing the epithelial-mesenchymal transition in patients with breast cancer. Furthermore, PLS3 may be an excellent biomarker for identifying groups at risk of recurrence or with a poor prognosis.
