Abstract
Background: Pancreatic cancer has a poor prognosis because of its high refractoriness to chemotherapy and tumour recurrence, and these properties have been attributed to cancer stem cells (CSCs). MicroRNA (miRNA) regulates various molecular mechanisms of cancer progression associated with CSCs. This study aimed to identify the candidate miRNA and to characterise the clinical significance. Methods: We established gemcitabine-resistant Panc1 cells, and induced CSC-like properties through sphere formation. Candidate miRNAs were selected through microarray analysis. The overexpression and knockdown experiments were performed by evaluating the in vitro cell growth and in vivo tumourigenicity. The expression was studied in 24 pancreatic cancer samples after laser captured microdissection and by immunohistochemical staining. Results: The in vitro drug sensitivity of pancreatic cancer cells was altered according to the miR-1246 expression via CCNG2. In vivo, we found that miR-1246 could increase tumour-initiating potential and induced drug resistance. A high expression level of miR-1246 was correlated with a worse prognosis and CCNG2 expression was significantly lower in those patients. Conclusions: miR-1246 expression was associated with chemoresistance and CSC-like properties via CCNG2, and could predict worse prognosis in pancreatic cancer patients.

Abstract
This randomized, multicenter study compared the efficacy of docetaxel with or without capecitabine following fluorouracil/epirubicin/cyclophosphamide (FEC) therapy in operable breast cancer and investigated the role of Ki67 as a predictive biomarker. Patients were randomized to 4 cycles of docetaxel/capecitabine (docetaxel: 75 mg/m2 on day 1; capecitabine: 1,650 mg/m2 on days 1–14 every 3 weeks) or docetaxel alone (75 mg/m2 on day 1 every 3 weeks) after completion of 4 cycles of FEC (5-fluorouracil 500 mg/m2, epirubicin 100 mg/m2 and cyclophosphamide 500 mg/m2 on day 1 every 3 weeks). The primary endpoint was the pathological complete response (pCR) rate. Predictive factor analysis was conducted using clinicopathological markers, including hormone receptors and Ki67 labeling index (Ki67LI). A total of 477 patients were randomized; the overall response in the docetaxel/capecitabine and docetaxel groups was 88.3 and 87.4 %, respectively. There were no significant differences in the pCR rate (docetaxel/capecitabine: 23 %; docetaxel: 24 %; p = 0.748), disease-free survival, or overall survival. However, patients with mid-range Ki67LI (10–20 %) showed a trend towards improved pCR rate with docetaxel/capecitabine compared to docetaxel alone. Furthermore, multivariate logistic regression analysis showed pre-treatment Ki67LI (odds ratio 1.031; 95 % CI 1.014–1.048; p = 0.0004) to be a significant predictor of pCR in this neoadjuvant treatment setting. Docetaxel/capecitabine (after 4 cycles of FEC) did not generate significant improvement in pCR compared to docetaxel alone. However, exploratory analyses suggested that assessment of pre-treatment Ki67LI may be a useful tool in the identification of responders to preoperative docetaxel/capecitabine in early-stage breast cancer.

Abstract
PURPOSE Better treatments for triple-negative breast cancer (TNBC) are needed. To address this need, we studied the effects of preoperative metronomic paclitaxel/cyclophosphamide/capecitabine (mPCX) followed by 5-fluorouracil (FU)/epirubicin/cyclophosphamide (FEC) as preoperative chemotherapy in TNBC patients. METHODS Forty primary TNBC patients received four cycles of metronomic paclitaxel (80 mg/m(2) on Days 1, 8, and 15), cyclophosphamide (50 mg/body daily), and capecitabine (1,200 mg/m(2) daily), followed by four cycles of 5-FU (500 mg/m(2)), epirubicin (100 mg/m(2)), and cyclophosphamide (500 mg/m(2)) every 3 weeks. The primary end point was the pathological complete response (pCR) rate. RESULTS Forty patients formed the intent-to-treat population. The median dose intensities of paclitaxel, cyclophosphamide, and capecitabine were 89.7, 92.1, and 89.8%, respectively. Five patients discontinued mPCX and two discontinued FEC, primarily because of adverse events, resulting in a per-protocol population (PPS) of 33 patients. The pCR (ypT0/Tis ypN0) rate was 47.5% (19/40) in the intent-to-treat population and 54.5% (18/33) in the PPS. The clinical response rates were 36/40 (90.0%) and 31/33 (93.9%) in the intent-to-treat and PPS, respectively. The breast conservation rate was 72.7% (24/33), and 5/13 patients underwent partial resection instead of pre-planned total mastectomy. Grade 3-4 adverse events included neutropenia (35%), leukopenia (25%), and hand-foot syndrome (8%). CONCLUSIONS Metronomic PCX followed by FEC chemotherapy was associated with a high pCR rate and low toxicity in TNBC patients. Further studies of this regimen in larger numbers of patients are warranted.

Abstract
We investigated the disease-free survival (DFS) of HER2-positive primary breast cancer patients treated with neoadjuvant chemotherapy plus trastuzumab, as well as predictive factors for DFS and pathologic response. Data from 829 female patients treated between 2001 and 2010 were collected from 38 institutions in Japan. Predictive factors were evaluated using multivariate analyses. The 3-year DFS rate was 87 % [95 % confidence interval (CI) 85-90]. The pathologic complete response (pCR: ypT0/is + ypN0) rate was 51 %. The pCR rate was higher in the ER/PgR-negative patients than in the ER/PgR-positive patients (64 vs. 36 %, P < 0.001). Patients with pCR showed a higher DFS rate than patients without pCR (93 vs. 82 %, P < 0.001). Multivariate analysis revealed three independent predictors for poorer DFS: advanced nodal stage [hazard ratio (HR) 2.63, 95 % CI 1.36-5.21, P = 0.004 for cN2-3 vs. cN0], histological/nuclear grade 3 (HR 1.81, 95 % CI 1.15-2.91, P = 0.011), and non-pCR (HR 1.98, 95 % CI 1.22-3.24, P = 0.005). In the ER/PgR-negative dataset, non-pCR (HR 2.63, 95 % CI 1.43-4.90, P = 0.002) and clinical tumor stage (HR 2.20, 95 % CI 1.16-4.20, P = 0.017 for cT3-4 vs. cT1-2) were independent predictors for DFS, and in the ER/PgR-positive dataset, histological grade of 3 (HR 3.09, 95 % CI 1.48-6.62, P = 0.003), clinical nodal stage (HR 4.26, 95 % CI 1.53-13.14, P = 0.005 for cN2-3 vs. cN0), and young age (HR 2.40, 95 % CI 1.12-4.94, P = 0.026 for ≤40 vs. >40) were negative predictors for DFS. Strict pCR (ypT0 + ypN0) was an independent predictor for DFS in both the ER/PgR-negative and -positive datasets (HR 2.66, 95 % CI 1.31-5.97, P = 0.006 and HR 3.86, 95 % CI 1.13-24.21, P = 0.029, respectively). These results may help assure a more accurate prognosis and personalized treatment for HER2-positive breast cancer patients.

Abstract
Andersen-Tawil syndrome (ATS) is an inherited disease characterized by ventricular arrhythmias, periodic paralysis, and dysmorphic features. It results from a heterozygous mutation of KCNJ2, but little is known about mosaicism in ATS. We performed genetic analysis of KCNJ2 in 32 ATS probands and their family members and identified KCNJ2 mutations in 25 probands, 20 families who underwent extensive genetic testing. These tests revealed that seven probands carried de novo mutations while 13 carried inherited mutations from their parents. We then specifically assessed a single proband and the respective family. The proband was a 9 year old girl who fulfilled the ATS triad and carried an insertion mutation (p.75_76insThr). We determined that the proband's mother carried a somatic mosaicism and that the proband's younger brother also carried the ATS phenotype with the same insertion mutation. The mother, who exhibited mosaicism, was asymptomatic, although she exhibited Q(T)U prolongation. Mutant allele frequency was 11% as per TA cloning and 17.3% as per targeted deep sequencing. Our observations suggest that targeted deep sequencing is useful for the detection of mosaicism and that the detection of mosaic mutations in parents of apparently sporadic ATS patients can help in the process of genetic counseling.

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
Abstract
Background
Patients (pts) without pathologic complete response (pCR) after neoadjuvant chemotherapy (NAC) have a poor prognosis compared with pts achieving a pCR with NAC. It is not clear whether further systemic chemotherapy is beneficial for pts with no pCR. CREATE-X (UMIN000000843) is an ongoing collaborative Korean (KRN)/Japanese (JPN) prospective multicenter open-label randomized phase III trial evaluating this clinical question using capecitabine (X) in pts with no pCR after NAC. We report first safety results, focusing on hand-foot syndrome (HFS), the timing of radiotherapy (RT) and hormone therapy (HT), and differences between KRN and JPN pts.
Methods
Pts with residual invasive cancer after anthracycline- and/or taxane-containing NAC were randomized to standard post-surgical treatment (RT, HT as appropriate) with or without 8 cycles of X (1250 mg/m2 bid, days 1–14 q3w). RT was given before or after X. Pts with hormone receptor (HR)-positive disease received HT either with or after X, according to each center's prespecified standard practice. After evaluation of the tolerability of 6 cycles of X in the first 50 pts, the independent data monitoring committee recommended extending X to 8 cycles.
Results
Between Feb 2007 and Jul 2012, 910 pts were enrolled (304 in Korea, 606 in Japan). At the time of data cut-off (May 20, 2013), data were available from 866 pts. Median age was 48 years in both arms. In the investigational arm, RT was given before X in 260 pts and after X in 33 pts; 73 pts received prophylactic vitamin B6 (VB6). In HR-positive pts HT was given with X in 200 pts and after X in 24 pts. The relative dose intensity of X was 85.7% in JPN pts and 95.2% in KRN pts. Grade (G) 3/4 neutropenia, HFS (G3 only), fatigue, and diarrhea were significantly (p<0.05) more common with X than no X. G3 HFS occurred in 11.1% of pts receiving X, and was significantly more common in JPN vs KRN pts (p = 0.016). No significant difference in HFS was observed between pts who received vs did not receive VB6 (p = 0.392). G3/4 alanine aminotransferase (ALT) abnormalities were significantly more common in pts receiving RT after vs before X (p<0.001) and in pts receiving HT after vs concurrently with X (p<0.001).

Conclusions
Addition of 8 cycles of X to standard adjuvant therapy is feasible and tolerable, resulting in a modest yet acceptable increase in toxicities. The timing of RT and HT administration relative to X influenced the incidence of adverse events. HFS was more common in JPN than KRN pts, although further investigation of the potential cause of this difference is required. These findings should be interpreted in light of efficacy data, expected in 2015.

Abstract
Abstract
BACKGROUND:
Addition of trastuzumab to neoadjuvant chemotherapy (NAC) improved pathologic complete response (pCR) rate in HER2-positive breast cancer. Although recent trials have shown favorable prognosis with NAC plus trastuzumab, clinicopathological factors to predict the outcome have not been fully understood. The aim of this study was to investigate the survival after NAC with trastuzumab and to explore the predictive factors.
PATIENTS AND METHODS:
This is a multicenter retrospective observational study. Patients with HER2-positive primary breast cancer treated with NAC plus trastuzumab from 2001 to 2010 were identified from the institutional database. Primary end point was disease-free survival (DFS). pCR was defined as ypT0/is+ypN0. Kaplan-Meier method was used to estimate DFS. Logistic regression and proportional hazard analysis were used to identify clinicopathological factors to predict pCR and DFS, respectively.
RESULTS:
733 patients were included in the analysis (whole dataset). 425 were ER/PgR-negative (HR- dataset) and 306 were ER/PgR-positive (HR+ dataset). Radiation therapy was performed in 90% of lumpectomy and 31% of mastectomy. Hormonal therapy was performed in 84% of HR+ dataset. pCR rate was 45% in whole dataset, 60% in HR- dataset, and 34% in HR+ dataset. Table 1 showed the result of multivariate analysis for pCR in whole dataset. When HR+ and HR- dataset were analyzed separately, no definitive predictors for pCR were identified in multivariate analysis. Although the patients with pCR showed a significantly favorable prognosis than those without pCR at 3 years DFS, in whole dataset (93% vs 83%, p<0.0001) and HR- dataset (94% vs 80%, p<0.0001), there was no significant difference in HR+ dataset (89% vs 86%, p = 0.10). Different predictors were selected for DFS when multivariate analysis was conducted separately between HR- and HR+ dataset (Table 2).
CONCLUSIONS:
In this observational study, we clarified predictors for pCR and DFS in HER2-positive patients treated with neoadjuvant trastuzumab containing therapy based on tumor subtype. Our results may help us to predict the prognosis more precisely and to simulate the disease course.

Abstract
Abstract
BACKGROUND: Sentinel node biopsy (SNB) for the node negative breast cancer is standard treatment as an accurate assessment of axillary lymph node status; however, axillary node dissection is a standard procedure for the node positive breast cancer. Neoadjuvant chemotherapy (NAC) has become the standard of care for patients with locally advanced breast cancer. It is reported that 40% of node positive disease convert to node negative after NAC. It remains controversial whether SLB could be applied to patients who present with node-positive disease before neoadjuvant chemotherapy. In this study, we evaluated the accuracy of SNB following NAC in breast cancer patients presenting with cytology-proven axillary node metastasis before chemotherapy.
METHODS: A multicenter prospective study was performed from September 2011 to April 2013 in 101 breast cancer patients with positive axillary nodes, proven by ultrasound-guided fine-needle aspiration at initial diagnosis (T1-3, N1, M0). After the confirmation of patients as clinically node-negative by preoperative imaging following NAC, all patients underwent breast surgery, with SNB and complete axillary lymph node dissection. The sentinel nodes were examined by hematoxylin-eosin staining, immunohistochemical analysis or one-step nucleic acid amplification assay (OSNA).The false negative rate and detection rate were analyzed.
RESULTS: Among the 101 patients analyzed, all cases presented with invasive ductal carcinoma. with a mean tumor size of 3.4cm. Thirty-six cases were hormone receptor (HR) positive and HER2 negative (Lum), 14 cases were HR positive and HER2 positive (Triple-Positive), 27 cases were positive for HER2 (HER2-enriched), and 24 cases were Triple-Negative. After neoadjuvant chemotherapy, a complete clinical response in the primary tumor was seen in 24.8%(25/101), a partial response in 66.3%(67/101), and no response in 7.9%(8/101). Pathological complete response of primary tumor was 39.6%. The pathological complete nodal response rate was 42.2%. The sentinel lymph node could be identified in 91 of 101 cases (90.1%); 88.9% (32/36) of patients with Lum, 100%(14/14)of those with Triple-Positive, 85.2% (23/27) of those with HER2-enriched, and 91.7% (22/24)% of those with Triple-Negative breast cancer subtype. The false negative rate was 12.7%; 35.7 (5/14) for Lum, 0% (0/8) for Triple-Positive, 5.0% (1/20) for HER2-enriched, and 7.7% (1/13) for Triple-Negative subtype (P = 0.03).
CONCLUSION: SNB following NAC in patients with node-positive breast cancer was found to be technically feasible, but is not recommended for the Lum subtype. However, it might be safely considered in selected patients, those with Triple-Positive, HER2-enrich and Triple-Negative subtype breast cancers.

Abstract
Abstract
Background: We compared and evaluated three 6-cycle, docetaxel and cyclophosphamide (TC)-containing chemotherapy regimens in a multicenter randomized phase II study. The main aim was to investigate whether anthracyclines are needed or can be omitted, and whether the order of chemotherapy is important, for treating luminal-type breast cancer.
Methods: We recruited patients (pts) with ER-positive, HER2-negative breast cancer aged 20–70 years, and histo-pathologically invasive breast cancer (T1c-3, N0-1, M0), T≤7cm. Pts were randomized to 3 groups for the following treatments: 6 cycles of TC; 3 cycles of 5-FU/epirubicin/cyclophosphamide (FEC) followed by 3 cycles of TC (FEC-TC); and 3 cycles of TC followed by 3 cycles of FEC (TC-FEC). TC treatment consisted of administration of docetaxel at 75 mg/m2 and cyclophosphamide at 600 mg/m2 once every 3 weeks. FEC treatment consisted of administration of 5-FU at 500 mg/m2, epirubicin at 100 mg/m2, and cyclophosphamide at 500 mg/m2 once every 3 weeks. We aimed to enroll 65 pts per group based on an expected pCR rate among regimens of adding 10% at a threshold of 9%. The primary endpoint was pathological complete response (pCR) rate. Secondary endpoints were overall response rate (ORR), breast conservation rate and safety.
Results: A total of 195 pts (median age, 49.5 years (range, 26–69); median tumor size, 32.8 mm (range, 9–82); 91 pts with N(+) (51%)) were enrolled and randomized as follows: FEC-TC (n = 65), TC-FEC (n = 63), and TC group (n = 67). There were no differences in backgrounds among groups. Both the intention-to-treat population and the safety analysis set included 65, 63 and 65 pts in these groups, respectively. The 6-cycle treatment completion rates were 96.9%, 96.8% and 84.6%, respectively. pCR, defined as yT0/isyN0, was achieved by 9.2% of pts in the FEC-TC group, 8.1% in the TC-FEC group, and 15.9% in the TC group (p = 0.321). A quasi pCR in breast (yT0/is and near pCR) was achieved by 13.9%, 14.5%, and 17.5%, respectively. These responses did not differ among the 3 groups. ORRs, assessed by MRI or CT, were 75.8% (CR: 12.9%), 75% (CR: 5%), and 82.2% (CR: 17.9%) in the FEC-TC, TC-FEC and TC groups, respectively. Breast conservation rates were 50.8%, 45.2%, and 73.0%, respectively.Adverse events of Grade≥3 were observed in 20.0%, 27.0%, and 20.3% of pts in the FEC-TC, TC-FEC, and TC groups, respectively, with no significant differences. Febrile neutropenia was observed in 17.2%, 21.0%, and 11.3%, respectively, but in most cases it was managed sufficiently on an outpatient basis. Of 28, 27 and 23 pts in these groups in whom mastectomy was planned, 9 (32%), 5 (19%), and 10 (44%) were successfully converted to undergo breast-conserving surgery. Of 37, 35 and 40 pts in the FEC-TC, TC-FEC and TC groups in whom breast-conserving surgery was planned, 13 (35%), 12 (34%), and 4 (10%) underwent mastectomy.
Conclusion: Six cycles of TC had therapeutic effects and safety equivalent to FEC-TC and TC-FEC. The 3 treatment groups showed similar pCR rates, although the breast conservation rate was significantly higher in the TC group than in the other 2 groups. It may be possible to conduct preoperative chemotherapy for pts with ER-positive breast cancer without using an anthracycline.

Abstract
The caveolin 1 to caveolin 2 (CAV1-CAV2) gene region on chromosome 7q31 has been reported to be associated with susceptibility to primary open angle glaucoma (POAG) and normal tension glaucoma (NTG) in previous studies. We investigated whether genetic variants in the CAV1-CAV2 region are associated with NTG in Japanese patients. Two hundred and ninety-two Japanese patients with NTG and 352 Japanese healthy controls were recruited. We genotyped three single-nucleotide polymorphisms; that is, rs1052990, rs4236601, and rs7795356, in the CAV1-CAV2 gene region and assessed the allelic diversity among cases and controls. The frequency of the minor allele (G) of rs1052990 was significantly decreased in NTG cases compared with controls (P=0.014, OR=0.71), whereas NTG or POAG cases had a significantly higher frequency of the allele than controls in previous studies. Conversely, rs7795356 did not show any significant association with NTG cases, and rs4236601 was monomorphic in the Japanese study population. Our findings did not correspond with previous positive results, suggesting that CAV1-CAV2 variants studied in the present study are not important risk factors for NTG susceptibility in all populations. Further studies are needed to elucidate the possible contribution of the CAV1-CAV2 region to the development of glaucoma.
