Abstract
Background and Aim Post‐endoscopic retrograde cholangiopancreatography (ERCP) pancreatitis (PEP) is the most serious adverse event of ERCP. Therefore, it is important to identify high‐risk patients who require prophylactic measures. The aim of this study was to develop a practical prediction model for PEP that identifies high‐risk patients. Methods Patients who underwent ERCP at three tertiary hospitals between April 2010 and September 2012 were enrolled. The dataset was divided into a training set (two centers) and validation set (one center). Using the training set, univariable and multivariable analyses were performed to identify predictive factors for PEP. We constructed a scoring system and evaluated reproducibility using the validation set. Results A total of 2719 ERCPs were analyzed. PEP developed in 133 cases (4.9%). Risk factors (adjusted odds ratios [OR]) in the training set were a history of PEP (OR: 4.2), intact papilla (OR: 2.4), difficult cannulation (OR: 1.9), pancreatic guidewire‐assisted biliary cannulation (OR: 2.2), pancreatic injection (OR: 2.1), pancreatic intraductal ultrasonography (IDUS)/sampling from the pancreatic duct (OR: 2.2), and biliary IDUS/sampling from the biliary tract (OR: 2.8). A scoring system was constructed using these seven clinical variables. The areas under the receiver‐operating characteristic curve of this model were 0.799 in the training set and 0.791 in the validation set. In the high‐risk group at a score of 3 or higher, the incidence of PEP was 13.4%, and all severe/fatal cases were in the high‐risk group. Conclusions This scoring system helps to predict each patient's risk and select preventive measures.

Abstract
A 54-year-old man presented with melena and was conservatively monitored for duodenitis. He developed epigastric pain, and dynamic computed tomography revealed abnormal blood flow in the pancreatic head. The endoscopic retrograde cholangiography revealed that the common bile and pancreatic ducts were simultaneously enhanced, thereby indicating the perforation of an arteriovenous malformation into both ducts. Despite medical treatment, the epigastric pain rapidly worsened and therefore, pancreatoduodenectomy was performed. The present report suggests that if the patient's general condition permits, surgical resection should be actively considered for the treatment of symptomatic pancreatic arteriovenous malformation.

Abstract
Abstract
OBJECTIVE: The RESPECT trial compared 1-year trastuzumab monotherapy with trastuzumab plus standard chemotherapy as a postoperative adjuvant therapy in HER2-positive elderly breast cancer patients. Primary objective of this study was to verify the noninferiority of 1-year trastuzumab monotherapy to trastuzumab plus chemotherapy in terms of disease free survival, and the planned analysis showed that the difference of restricted mean survival time between two groups at 3 years was 0.45 months (reported by Sawaki at ASCO2018). This report assesses the patients-reported outcomes and health-related quality of life (HRQoL).
PATIENTS AND METHODS: The study was done at 99 hospitals in Japan. Elderly women (70 to 80 years old) with HER2-positive, stageI-IIIA invasive breast cancer treated by surgery with clear resection margins were randomly assigned to receive either 1-year trastuzumab or 1-year trastuzumab plus standard chemotherapy, stratified by age, hormone-receptor status, pathological lymph node metastasis and institution. Patients completed questionnaires at baseline, 2 months, 1year, and 3 years after protocol treatment started. The primary outcome was global HRQoL assessed using Functional Assessment of Cancer Therapy-General (FACT-G) total score, and secondary outcomes were chemotherapy-induced peripheral neuropathy (CIPN), instrumental activities of daily living (IADL), anxiety, depression, and subjective happiness. We did the analyses by intention to treat, including patients who completed questionnaires at baseline before start of protocol treatment, and 5point or more change is meaningful in FACT-G total score. This study is registered with ClinicalTrials.gov, NCT01104935.
RESULTS: Between Oct 2009 and Oct 2014, 275 patients were enrolled in the study, of whom 9 patients were excluded: 135 assigned to trastuzumab monotherapy and 131 assigned to trastuzumab plus chemotherapy. We detected significant difference between treatment groups for: clinically meaningful HRQoL deterioration rate at 2 months (31% for trastuzumab monotherapy vs 48% for trastuzumab plus chemotherapy; p=0.016) and at 1year (19% vs 38%; p=0.009), clinically meaningful HRQoL improvement rate at 2 months (38% for trastuzumab monotherapy vs 15% for trastuzumab plus chemotherapy; p<0.01) and at 1year (43% vs 25%; p=0.021), severe sensory CIPN rate at 2months (1.9% for trastuzumab monotherapy vs 14.4% for trastuzumab plus chemotherapy; p=0.001), IADL score at 1year (11.97 for trastuzumab monotherapy vs 11.54 for trastuzumab plus chemotherapy; p<0.042), Hospital Anxiety and Depression Scale score at 2months (8.92 for trastuzumab monotherapy vs 10.79 for trastuzumab plus chemotherapy; p<0.003), and subjective happiness score at 1year (12.8 for trastuzumab monotherapy vs 11.8 for trastuzumab plus chemotherapy; p<0.024).
CONCLUSION: Given the small advantage of adjuvant trastuzumab plus chemotherapy compared to trastuzumab monotherapy for elderly HER-2 positive breast cancer women, decisions about treatment should be informed by the risk for adverse health effects associated with chemotherapy.

Abstract
Abstract
OBJECTIVE: The effect of trastuzumab(Tmab) or chemotherapy on cognitive function has not been fully understood, especially in elderly breast cancer patients. The RESPECT trial compared 1-year(yr) Tmab monotherapy with Tmab plus standard chemotherapy as adjuvant therapy in elderly patients with HER2-positive breast cancer. The primary objective was to verify the noninferiority of 1-yr Tmab monotherapy compared to Tmab plus chemotherapy in terms of disease-free survival, and the planned analysis showed that the difference of restricted mean survival time between two groups at 3 yrs was 0.45 months (Sawaki at ASCO2018). The goal of this report was to assess the impact of the treatment groups on longitudinal cognitive function.
PATIENTS AND METHODS: The study was performed with patients from 99 hospitals in Japan. Elderly women with HER2-positive, stage I-IIIA invasive breast cancer surgery treated with clear resection margins were randomly assigned to either receive 1-yr Tmab or 1-yr Tmab plus standard chemotherapy. 15 institutions participated in the cognitive sub-study. Cognitive function was assessed using the Mini-Mental State Examination (MMSE) at baseline and at 1 and 3 yrs after treatment. The primary outcome was the amount of change in the MMSE score from the baseline. A linear mixed-effects model was used for comparisons of change in the MMSE score between groups, controlling for time and baseline score. Secondary outcomes were the proportion of both suspected mild dementia (MMSE≤27) and dementia (MMSE≤23) at each time point.
RESULTS: Between October 2009 and October 2014, 275 patients were enrolled in the RESPECT trial, and 57 patients were enrolled in the cognitive function sub-study with 2 patients subsequently excluded. The 55-patient sub-study comprised 29 patients assigned to the Tmab monotherapy group and 26 patients assigned to the Tmab plus chemotherapy group. Primary analysis revealed that change in the MMSE score was not significantly different between the two groups (difference −0.6 at 1 yr and −0.9 at 3 yrs; p=0.136), whereas the baseline score was the only significant factor that had an effect on the amount of change in the MMSE score (p<0.001). The proportions of suspected mild dementia at baseline, and at 1 yr and 3 yrs were 15.4, 32.0, and 41.7% in the Tmab monotherapy group, and 45.8, 17.6, and 28.6% in the Tmab plus chemotherapy group. The proportions of suspected mild dementia at baseline were significantly higher in the Tmab plus chemotherapy group (p=0.04). The proportions of suspected dementia at baseline, and at 1 yr and 3 yrs were 0%, 0%, and 4.2% in the Tmab monotherapy group, and 4.2%, 0%, and 4.8% in the Tmab plus chemotherapy group. There were no significant differences in the proportions of suspected dementia between the treatment groups at each time point.
CONCLUSION: Postoperative chemotherapy for elderly breast cancer patients was considered to have little effect on the onset of dementia during the follow-up period of 3 yrs. Further long-term observation is necessary to obtain a significant conclusion.

Abstract
Introduction
Oral mucositis is a clinically significant complication of mucotoxic cancer therapy. The incidence of oral mucositis (any grade) as an adverse drug reaction of everolimus is 58%, while an analysis of Asian people has reported its occurrence as 81%.This study hypothesizes that the occurrence of oral mucositis will reduce with professional oral care (POC) administered prior to everolimus treatment.
Method:
This was a randomized, multi-center, open-label, phase III study, to evaluate the efficacy of POC in preventing mucositis induced by everolimus in postmenopausal, estrogen receptor (ER)-positive, metastatic breast cancer patients. Patients were randomized into POC and control groups (1:1 ratio). All patients received everolimus with exemestane and continued the everolimus until disease progression. In the POC group, patients were subjected to teeth surface cleaning, scaling and tongue cleaning, before initiating everolimus, and continued to receive weekly POC from dentist or oral surgeons throughout the 8 weeks of treatment. In the control group, patients brushed their own teeth and gargled with 0.9% sodium chloride solution or water. The primary end-point was to measure the incidence of all grades of oral mucositis. Target accrual was 200 patients with a 2-sided type I error rate of 5% and 80% power to detect 25% risk reduction. This trial has been registered at ClinicalTrials.gov, number NCT 02069093.
Result:
Between May 26, 2014 and Dec 28, 2017, we enrolled 174 women from 31 institutions; 168 were evaluable for efficacy but 5 were excluded (had not received the protocol treatment [n=4]; no efficacy data [n=1]). In 8 weeks, the incidence of grade 1 oral mucositis was significantly different between the POC group (76.5%, 62 of 81 patients) and control group (89.7%, 78 of 87 patients) (p=0.035). The incidence of grade 2 (severe) oral mucositis was also significantly different between the POC group (34.6%, 28 of 81 patients) and control group (54%, 47 of 87 patients) (p= 0.015). As a result of oral mucositis, 18 (22.2%) patients in the POC group and 28 (32.2%) in the control group had to undergo everolimus dose reduction.
Conclusion:
POC reduced the incidence and severity of oral mucositis in patients receiving everolimus and exemestane. This could be a new standard in oral care for patients undergoing this treatment.

Abstract
Abstract
Background: Anthracycline-containing regimens and taxane have been standard as the first-line chemotherapy for metastatic breast cancer (MBC). We conducted SELECT BC (randomized phase 3 study of taxane versus S-1 as first-line treatment for MBC) for evaluating the efficacy of S-1 for patients with HER2-negative MBC from 2006 to 2010 in Japan. This study demonstrated non-inferiority of S-1 in overall survival (OS) (median OS was 37.2 months in taxes group and 35.0 months in S-1 group (HR 1.05, 95% CI 0.86–1.27, p=0.015)), and superiority in health-related quality of life (HRQOL) to taxanes. S-1 was also shown as less toxic than taxane (Lancet Oncol 2016; 17: 90-98). S-1 might provide clinical benefit as first-line treatment for patients with HER2-negative MBC. To confirm this suggestion, we have conducted further study (randomized phase 3 study of anthracycline-containing regimens versus S-1 as first-line treatment for HER2-negative MBC: SELECT BC-CONFIRM) from 2011 to present, and a combined analysis of two randomized studies (SELECT-BC CONFIRM and SELECT-BC).
Methods: In SELECT BC-CONFIRM, 230 patients receiving first-line treatment for MBC were randomly assigned to either anthracycline group (n=115) or S-1 group (n=115). Anthracycline group patients received anthracycline-containing regimens (AC, EC, FAC, FEC, q3w) at the discretion of the treating physician. S-1 group patients received S-1 40–60 mg twice daily based on the patient's body surface area for 28 days on, 14-day off. The primary endpoint was OS, and secondary endpoints were progression-free survival (PFS), time to treatment failure (TTF), adverse events, HRQOL, and cost-effectiveness. The results were combined with SELECT-BC, to confirm the hypothesis that S-1 treatment is not inferior to the standard therapy (taxanes / anthracycline) for HER2-negative MBC.
Results: A combined analysis of the two studies showed that HR was 1.06, 95%CI 0.90-1.253, and p=0.0071 between the standard therapy group and S-1 group. In addition, the Bayesian posterior probability for which HR would be less than 1.333 was about 99.6%.
Conclusions: A combined analysis of SELECT BC-CONFIRM and SELECT BC clearly demonstrated that OS with S-1 was not inferior to that with the standard therapy in patients receiving first-line treatment for HER2-negative MBC. S-1 could become a standard therapy for this patient population.

Abstract
Abstract
Background:It is unclear how to define responsiveness to endocrine therapy (ET) during the clinical course of advanced breast cancer (ABC), especially in evaluation of the effect of sequential ET. Objective:The goal of the study was to evaluate the efficacy of second line treatment of physician's choice (2nd-line TPC) for estrogen receptor-positive (ER+) and HER2-negative postmenopausal ABC with very low or low sensitivity to initial ET. Methods:A multicenter prospective observational cohort study was performed for 2nd-line TPCs. ABC with low sensitivity to initial ET was defined as recurrence within 5 years (yrs) during adjuvant ET or progression within 9 months (mo.) of initial ET. Similarly, ABC with very low sensitivity to initial ET was defined as recurrence within 2 yrs during adjuvant ET or progression within 3 mo. of initial ET. The expected clinical benefit rate (CBR: defined as patients who achieved CR, PR or SD for 24 weeks) was 50%. The null hypothesis of a CBR of 30% was tested with a one-sided α of 5%. 90% confidence intervals (CIs) were calculated for hypothesis tests. Results: A total of 56 patients (pts) were enrolled, but 7 were ineligible and one discontinued before starting the protocol treatment. The median age was 66 yrs (range: 41-88) and the median BMI was 23.4 kg/m2 (16.4-31.9). All pts were ER+ and 80% were PgR+. Most of pts had a baseline PS of 0 or 1, 90% had invasive ductal carcinoma, and 10% had invasive lobular carcinoma. Postoperative recurrence was detected in 84% and these pts had a median duration of adjuvant ET of 30.5 mo. (5.3-58.9). De novo stage IV ABC was present in 16%, with a median duration of first-line ET of 5 mo. (2.3-10.8). Adjuvant chemotherapy including anthracycline- and/or a taxane-containing regimen was administered in 58% (29/49). As adjuvant ET before initial recurrence, 34 pts received non-steroidal aromatase inhibitors (AIs) (88.0%), 1 received a steroidal AI (2.3%), and 3 received a selective estrogen receptor modulator (SERM). As first line ET in de novo stage IV, 7 pts (14%) were treated with AIs or a SERM (1 case). 2nd-line TPCs were also used, with 40 pts receiving fulvestrant (82%), 5 receiving SERMs (10%), 3 receiving a mTOR inhibitor plus a steroidal AI (6%), and one patient receiving an AI alone. The overall CBR was 44.9% (90% CI: 34.6-57.6, p=0.009), and CBR was similar across following subgroups (PgR+: n=39, 51.3%, 90% CI: 39.6-65.2, p=0.0016; very low sensitivity group: n=17, 58.8%, 90% CI: 42.0-78.8, p=0.003; non-visceral metastases: n=25, 40%, 90% CI; 34.1-65.9, p=0.0175). However, there were not statistically significant CBR in PgR- (n=10, 20.0%, 90% CI; 8.73-50.7, p=0.617), fulvestrant subgroup (n=40, 40.0 %, 90% CI; 29.2-54.2, p=0.063), low sensitive group (n=32, 37.5%, 90% CI; 26.0-53.6, p=0.1326), and visceral metastases (n=24, 48%, 90%CI; 28.2-60.3 p=0.072). The median PFS was 7.1 mo. (95% CI: 5.6-10.6). Conclusion:This study shows that 2nd line ETs was effective and might be a valid option in the sequence of treatments for postmenopausal women with ABC with low sensitivity to initial ET. It was suggested that PgR and visceral metastasis were significant predictive factors for CBR.

Abstract
In this work, the frequency dependence of the known mechano-optical effect which occurs in the micellar isotropic phases (I) of mixtures of potassium laurate (KL), decanol (DeOH), and water is investigated in the range from 200mHz to 200Hz. In order to fit the experimental data, a model of superimposed damped harmonic oscillators is proposed. In this phenomenological approach, the micelles (microscopic oscillators) interact very weakly with their neighbors. Due to shape anisotropy of the basic structures, each oscillator i (i=1,2,3,...,N) remains in its natural oscillatory rotational movement around its axes of symmetry with a frequency ω_{0i}. The system will be in the resonance state when the frequency of the driving force ω reaches a value near ω_{0i}. This phenomenological approach shows excellent agreement with the experimental data. One can find f∼2.5, 9.0, and 4.0Hz as fundamental frequencies of the micellar isotropic phases I, I_{1}, and I_{2}, respectively. The different micellar isotropic phases I, I_{1}, and I_{2} that we find in the phase diagram of the KL-DeOH-water mixture are a consequence of possible differences in the intermicellar correlation lengths. This work reinforces the possibilities of technological applications of these phases in devices such as mechanical vibration sensors.

Abstract
Abstract
BACKGROUND: Previous findings from the PALOMA-2 study (N=666) demonstrated the efficacy and safety of PAL+LET as first-line ABC therapy versus placebo (PBO)+LET (Finn et al, NEJM. 2016). This analysis evaluated the efficacy and safety of PAL+LET by geographic region (North America [NA], Europe [EU], and Asia Pacific [AP]; data cutoff: Feb 26, 2016).
METHODS: Women with ER+/HER2– ABC who had not received prior systemic treatment in the advanced setting were randomized 2:1 to PAL (125 mg/d oral [3 wks on, 1 wk off])+LET (2.5 mg once daily) or PBO+LET.
RESULTS: This analysis included 267 patients from NA, 307 from EU, and 92 from AP. At baseline, demographics and disease characteristics generally were similar between regions. In the overall population (Table 1), PAL+LET demonstrated improvements versus PBO+LET in progression-free survival (PFS), objective response rate (ORR), and clinical benefit response rate (CBR). Similarly, PFS was longer and ORR and CBR were higher with PAL+LET versus PBO+LET in NA, EU, and AP subgroups (Table 1). All-grade treatment-emergent adverse events (AEs) (PAL+LET/PBO+LET) occurred in 99%/99% of patients in NA, 98%/92% in EU, and 100%/96% in AP. In the PAL+LET arm, neutropenia (all-grade/grade ≥3) was the most common AE in all regions. The incidence of neutropenia was numerically higher in AP (91%/84%) compared with NA (73%/65%) and EU (81%/62%). Grade 3 or 4 febrile neutropenia occurred in 4 (2%) NA patients, 4 (2%) EU patients, and no AP patients in the PAL+LET arm and in no patients in any of the regions in the PBO+LET arm.
CONCLUSIONS: PAL+LET showed improvement versus PBO+LET in PFS, ORR, and CBR in patients with ER+/HER2- ABC in NA, EU, and AP, with comparable magnitude of benefit between regions. With PAL+LET, neutropenia was the most commonly reported AE in all regions, with a numerically higher incidence reported in AP versus NA or EU; the safety profile was similar to previously reported results in the overall population.

Abstract
BACKGROUND AND PURPOSE The superior cervical ganglion and inferior ganglion of the vagus nerve can mimic pathologic retropharyngeal lymph nodes. We studied the cross-sectional anatomy of the superior cervical ganglion and inferior ganglion of the vagus nerve to evaluate how they can be differentiated from the retropharyngeal lymph nodes. MATERIALS AND METHODS This retrospective study consists of 2 parts. Cohort 1 concerned the signal intensity of routine neck MR imaging with 2D sequences, apparent diffusion coefficient, and contrast enhancement of the superior cervical ganglion compared with lymph nodes with or without metastasis in 30 patients. Cohort 2 used 3D neurography to assess the morphology and spatial relationships of the superior cervical ganglion, inferior ganglion of the vagus nerve, and the retropharyngeal lymph nodes in 50 other patients. RESULTS All superior cervical ganglions had homogeneously greater enhancement and lower signal on diffusion-weighted imaging than lymph nodes. Apparent diffusion coefficient values of the superior cervical ganglion (1.80 ± 0.28 × 10-3mm2/s) were significantly higher than normal and metastatic lymph nodes (0.86 ± 0.10 × 10-3mm2/s, P < .001, and 0.73 ± 0.10 × 10-3mm2/s, P < .001). Ten and 13 of 60 superior cervical ganglions were hypointense on T2-weighted images and had hyperintense spots on both T1- and T2-weighted images, respectively. The latter was considered fat tissue. The largest was the superior cervical ganglion, followed in order by the retropharyngeal lymph node and the inferior ganglion of the vagus nerve (P < .001 to P = .004). The highest at vertebral level was the retropharyngeal lymph nodes, followed, in order, by the inferior ganglion of the vagus nerve and the superior cervical ganglion (P < .001 to P = .001). The retropharyngeal lymph node, superior cervical ganglion, and inferior ganglion of the vagus nerve formed a line from anteromedial to posterolateral. CONCLUSIONS The superior cervical ganglion and the inferior ganglion of the vagus nerve can be almost always differentiated from retropharyngeal lymph nodes on MR imaging by evaluating the signal, size, and position.

Abstract
Abstract
As for the HER2-positive breast cancer, there are many cases to be effective for neoadjuvant chemotherapy in comparison with other intrinsic subtypes. However, pCR is not provided by neoadjuvant chemotherapy in all cases. [Aim] This study evaluated the effectiveness of a therapeutic strategy that switches chemotherapy, based on Ki-67 tumor expression after initial therapy, relative to that of standard chemotherapy in patients with HER2-positive breast cancer. [patients and methods] Patients were randomly assigned to the control arm or the Ki-67 response-guided arm (Ki-67 arm). Primary tumor biopsies were obtained before treatment, and after three once-weekly doses of paclitaxel and trastuzumab to assess the interim Ki-67 index. In the control arm, paclitaxel and trastuzumab was continued for a total of 12 doses, regardless of the interim Ki-67 index. In the Ki-67 arm, subsequent treatment was based on the interim Ki-67 index. Early Ki-67 responders continued to received paclitaxel plus trastuzumab for a total of 12 doses, while early Ki-67 non-responders were switched to epirubicin plus cyclophosphamide every 3 weeks for three cycles with once-weekly trastuzumab for a total of 12 doses. The primary endpoint was the pathological complete response (pCR) rate. [Results] When 237 patients were enrolled, an interim analysis was conducted in 200 patients. There was almost linear correlation between the Ki-67 reduction rate at interim assessment and the pCR rate. The pCR rate in Ki-67 early non-responders in the Ki-67 arm (23.6%; 95% CI, 12.4 to 34.9) was inferior to that in the control arm (44.1%; 31.4 to 56.7; p=0.025). A strong correlation was not found between the Ki-67 reduction rate and the clinical response rate (Spearman's correlation coefficient 0.22).

Conclusions: The pCR rate in the Ki-67 arm was inferior to that in the control arm.

The standard chemotherapy protocol remains as the recommended strategy for patients with HER2-positive breast cancer.

Abstract
BACKGROUND The present study assessed conservative management of acute cholecystitis (AC) with a focus on percutaneous transhepatic gallbladder aspiration (PTGBA). METHODS Consecutive 275 patients with AC who underwent PTGBA were reviewed. Patients aged ≥80 years and/or with American Society of Anesthesiologists score III to IV and/or performance status 3 to 4 were defined as high risk. Patients were classified according to duration from symptom onset to first PTGBA: within 3 days (early PTGBA) or over 3 days (late PTGBA). They were also classified according to duration from first PTGBA to surgery: within 30 days (early surgery) or over 30 days (late surgery). RESULTS A total of 263 patients (95.6%) showed recovery after PTGBA. There were no significant differences in operating time, blood loss, operating procedure, conversion rate to open surgery, postoperative complications, or postoperative hospital stay between the early and late PTGBA groups or between the early and late surgery groups. No significant complications associated with PTGBA or surgery were observed, including in those at high risk. CONCLUSIONS Percutaneous transhepatic gallbladder aspiration can be a useful alternative for most patients with AC, including those at high risk. Elective cholecystectomy can be performed safely regardless of the timing of PTGBA or surgery.

Abstract
Purpose The goal of chemotherapy for metastatic breast cancer (MBC) is to prolong survival and maintain health-related quality of life. This study aimed to evaluate long-term health status of patients with MBC who participated in the phase III randomized SELECT BC trial. Methods In the SELECT BC trial, patients were randomly allocated to the S-1 or taxane (paclitaxel or docetaxel) arm. Health status was assessed by EQ-5D at pre-treatment, 3 and 6 months after randomization, and every 6 months thereafter to the extent possible. Least square mean scores were assessed to compare EQ-5D index values between groups. Time to deterioration analysis was also performed by defining the minimally important difference of EQ-5D as 0.05 or 0.1. Results The number of patients for EQ-5D analysis was 175 and 208 in the taxane and S-1 arms, respectively. Least square mean EQ-5D index values up to 60 months were 0.741 (95 % CI [0.713–0.769]) in the taxane arm and 0.748 [0.722–0.775] in the S-1 arm. The EQ-5D index value during PFS up to 12 months in the S-1 was superior to the corresponding index value in the taxane (0.812 [0.789–0.834] vs. 0.772 [0.751–0.792], P = 0.009). Time to deterioration analysis also revealed that S-1 significantly delayed the deterioration of EQ-5D index value during the period before progression (P = 0.002 and 0.003). Conclusions Our findings suggest that the EQ-5D index value was higher in patients treated with S-1 during first-line chemotherapy. Considering non-inferiority of S-1 in terms of OS, obtained quality-adjusted life years may be greater in the S-1 arm.

Abstract
OBJECTIVE Skin barrier disruption often occurs in diseased and damaged skin conditions such as atopic dermatitis (AD). We focused the galectin-7 protein (Gal-7) as a biomarker of skin condition and assessed whether the content of Gal-7 in stratum corneum (scGal-7) could be used as an indicator of skin barrier disruption and as an index of local skin symptoms in AD patients. METHODS Alteration of Gal-7 expression levels in keratinocyte and scGal-7 contents after barrier disruption by sodium dodecyl sulphate were evaluated in vitro and in vivo, respectively. Correlation between scGal-7 content and transepidermal water loss (TEWL) was examined in 126 healthy subjects. We performed single measurements of scGal-7 contents in 34 AD patients and serial measurements of 15 inpatients among them. SC samples were collected by the tape-stripping method, and scGal-7 content was determined using enzyme-linked immunosorbent assay. RESULTS Gal-7 expression in keratinocytes increased after barrier disruption. The scGal-7 content reflected the disruption of the skin barrier. The scGal-7 contents and TEWL values correlated in healthy subjects. The scGal-7 level was higher in AD patients than in healthy subjects. The scGal-7 contents in the cheek and neck of AD patients significantly correlated with the total and local skin lesion severity scores. Serial measurements in the inpatients showed that the scGal-7 contents in the cheek and neck decreased in tandem with local severity scores in response to treatment. CONCLUSION Measurement of scGal-7 content in tape-stripped samples was useful for the evaluation of the skin barrier function in dry skin conditions such as AD.

Abstract
Abstract
Background: There are few randomized clinical trials examining adjuvant treatment in elderly breast cancer patients. While obtaining informed consent is essential for participation in clinical studies, there is little information on the frequency of agreement to participate among elderly patients. Furthermore, elderly patients might have specific reasons to decline participation.
Patients and Method: The National Surgical Adjuvant Study of Breast Cancer 07 (N-SAS BC 07) is a randomized clinical trial in women over 70 years with HER2-positive primary breast cancer. The primary aim was to investigate the benefit of trastuzumab monotherapy compared with the combination of trastuzumab and chemotherapy. Key inclusion criteria were as follows: women between 70 and 80 years old with HER2-positive breast cancer; underwent curative operation; stage I to IIIA; with sufficient organ function. Patients were randomized to receive either trastuzumab plus chemotherapy or trastuzumab monotherapy. The primary endpoint was disease-free survival, and the secondary endpoints were overall survival, relapse-free survival, safety, health-related quality of life, and cost effectiveness (NCT01104935). It was not possible to predict the number of patients who would agree to participate. In order to comprehensively assess the effect of postoperative adjuvant therapy, we evaluated the reasons why eligible patients declined to participate. The patients were registered in a cohort study to prospectively evaluate the subsequent treatment options and prognosis (07-Cohort). This study examined the obtaining of informed consent for N-SAS BC 07 and the reasons for declining participation, and compared the clinicopathological backgrounds between the N-SAS BC 07 and 07-Cohort groups.
Results: 398 eligible patients have been recruited. Informed consent to participate in N-SAS BC 07 has been obtained from 275 patients (69%) and 123 patients (31%) who declined to participate in the RCT have been registered in the 07-Cohort. The common reasons to decline participation in the RCT were "cannot choose the treatment option (55%)", "refused chemotherapy (16%)", "wanted chemotherapy (9%)", "anxious about clinical studies (9%)" and "family opposition (8%)". The mean ages of the patients in N-SAS BC 07 and 07-Cohort were 73.9 and 74.6 years old, respectively. There were no differences in stage, surgical procedure, lymph node metastasis, or co-morbidities between the groups. ER-positive rate was higher in 07-Cohort group compared with N-SAS BC 07 group (53% vs. 37%, p=0.017, χ2 test).
Conclusion: While we expected the number of registrants to be small, since N-SAS BC 07 investigated whether elderly patients with HER2-positive breast cancer should undergo chemotherapy, almost 70% of the patients accepted informed consent. The most common reason to decline participation in N-SAS BC 07 was "cannot choose the treatment option" and the majority refused chemotherapy. Furthermore, ER-positivity was higher in the 07-Cohort group, which suggested that ER expression in the patients with HER2-positive breast cancer might influence their decision to participate in the study or to choose the treatment option.

Abstract
Abstract
Background:
In patients with estrogen receptor (ER)-positive advanced breast cancer, everolimus plus exemestane prolongs progression-free survival compared to exemestane monotherapy. However, as an adverse event from everolimus, oral mucositis (all grades) has been reported in 58% of all patients and 81% of Asian patients. Although no established prevention method is available, a previous study reported that professional oral care might prevent oral mucositis, and dentists have hypothesized that such care can reduce the occurrence of oral mucositis induced by everolimus. To evaluate this hypothesis, we compare the incidence of oral mucositis with and without professional oral care.
Method:
This is a randomized, multi-center, open-label, phase III study to evaluate the efficacy of professional oral care in preventing oral mucositis induced by everolimus in postmenopausal ER-positive metastatic breast cancer (MBC). Patients will be randomized into professional oral care and control groups (1:1 ratio). All patients will receive everolimus (10 mg daily) with exemestane (25 mg daily) and will continue everolimus until disease progression. Before the initiation of everolimus, instruction on a professional brushing method will be provided to both groups by specialists. In the professional oral care group, patients will receive teeth surface cleaning, scaling, and tongue cleaning before starting everolimus, and will continue to receive professional oral care weekly from oral surgeons throughout the 8 week treatment. In the control group, patients will brush their own teeth and gargle with 0.9% sodium chloride solution or water. The primary endpoint is the incidence of all grades of oral mucositis. The secondary endpoints are the incidence of over grade 2 and over 3 oral mucositis as determined by an oncologist and oral surgeons. The endpoints include onset and duration of oral mucositis. Major eligibility criteria include: 1) Postmenopausal women with ER positive MBC, and 2) No more than one prior chemotherapy treatment for MBC. Target accrual is 200 patients with a two-sided type I error rate of 5% and 80% power to detect 25% risk reduction. This study has just begun, and 5 of a planned 200 patients have been enrolled. (This study was registered with the UMIN 000016109).

Abstract
Abstract
Background: There is a high risk of under-reporting subjective toxicities by physicians, even when collected prospectively in clinical trials. It has been recommended to include patient reported measures regarding symptoms in prospective clinical comparative effectiveness trials. However, there have been few reports of agreement in endocrine related symptoms between patient and physician reporting.
Patients and Method: The National Surgical Adjuvant Study of Breast Cancer 06 (N-SAS BC 06) is a multicenter, randomized clinical trial of postmenopausal, hormone receptor-positive breast cancer patients, with a two-stage (preoperative and postoperative) enrollment, and intervention. The primary aim was to evaluate the need for adjuvant chemotherapy in the treatment of postmenopausal breast cancer patients who responded to neoadjuvant treatment with Letrozole (LET) for 24-28 weeks. After surgery, responders were randomized into two arms receiving either chemotherapy plus LET, or LET alone. The primary endpoint was disease-free survival, and the secondary endpoints included adverse events, quality of life and health economic evaluation. This study enrolled 497 subjects from the N-SAS BC 06 who were evaluated by Patient Reported Outcomes (PROs). The concordance rate between Clinician Reported Outcomes (CROs) and PROs in their endocrine symptoms during neoadjuvant endocrine therapy was examined. Symptoms were collected prospectively by physicians using the Common Toxicity Criteria for Adverse Events at enrollment, i.e., baseline, and 4 and 16 weeks after starting neoadjuvant LET. Patients also completed the FACT-G (General), B (Breast), ES (Endocrine Symptoms), and HADS. The endocrine symptoms according to the PROs, included nausea, hot flushes, cold sweats, headaches, and HADS-Depression score. In FACT, "Not at all" was used to express the absence of the symptoms, and "A little bit", "Some-what", "Quite a bit", and "Very much" were used to express the presence of symptoms. The HADS-Depression score threshold was 10/11. According to the CROs, grade 0 was defined as the absence of symptoms and grade 1 or more was defined as the presence of symptoms. Cohen's kappa was used to determine the concordance between CROs and PROs. The sensitivity of CROs was also calculated.
Results: The calculated point estimates of Cohen's kappa at Weeks 4 and 16 after starting neoadjuvant LET were 0.12 and 0.01 for nausea, 0.16 and 0.18 for hot flushes, 0.12 and 0.09 for cold sweats, 0.03 and 0.02 for headaches, and 0.11 and 0.11 for dysthymia/depression, respectively; the concordance was quite low. The sensitivity of CROs at Weeks 4 and 16 after starting neoadjuvant LET was 0.07 and 0.03 for nausea, 0.16 and 0.17 for hot flushes, 0.1 and 0.08 for cold sweats, 0.03 and 0.03 for headaches, and 0.11 and 0.1 for dysthymia/depression, respectively; the sensitivity was quite low.
Conclusion: This study showed that there were big differences between CROs and PROs in endocrine symptoms associated with endocrine therapy for breast cancer and that physicians could not obtain sufficient information on the endocrine symptoms. It is recommended that PROs be used to evaluate adverse events caused by endocrine therapy.

Abstract
Abstract
Background: Health-related quality of life (HRQoL) is one of the important outcomes in cancer control trials and has increasingly become the one of the primary foci. Obtaining informed consent from participants is essential for participation in randomized controlled trials (RCTs), but the participation in these RCTs may directly influence HRQoL, because treatment options are determined according to the allocation schedule. To date, only a few studies have compared HRQoL between clinical trial participants and decliners.
Patients and Method: The National Surgical Adjuvant Study of Breast Cancer 07 (N-SAS BC 07) is a randomized controlled trial in women with HER2-positive primary breast cancer who are over 70 years of age. The primary aim was to investigate the benefit of trastuzumab monotherapy compared with combination therapy using trastuzumab and chemotherapy. The study concept and design were published in concept paper (Sawaki M. et al., Jpn J Clin Oncol. 2011). In this study, patients were randomized to receive either trastuzumab plus chemotherapy or trastuzumab monotherapy. The primary endpoint was disease-free survival, and the secondary endpoints were overall survival, relapse-free survival, safety, HRQoL, comprehensive geriatric assessment (CGA) and cost effectiveness (protocol ID; NCT01104935).
HRQoL and CGA were assessed at registration (baseline), 2 month, 1 year, and 3 years after the start of protocol treatments using the Functional Assessment of Cancer Therapy-General (FACT-G), Hospital Anxiety and Depression Scale (HADS), EuroQol 5 Dimension (EQ-5D), Tokyo Metropolitan Institute of Gerontology (TMIG) index of competence, and the Philadelphia Geriatric Center (PGC) Morale Scale.
The patients who declined to participate in N-SAS BC 07 were registered in a cohort study to prospectively evaluate the subsequent treatment options and prognosis (07-Cohort). The same questionnaire that was used in N-SAS BC 07 was used in 07-Cohort to evaluate HRQoL and CGA at entry.
Results: Patients were enrolled from October 2012 to October 2016. During this period, 275 and 123 patients were registered in N-SAS BC 07 and 07-Cohort, respectively. The mean age at entry of the patients in the N-SAS BC 07 and 07-Cohort groups was 73.9 and 74.6 years, respectively. The questionnaire response rates at baseline in the patients in N-SAS BC 07 and 07-Cohort groups were 89% and 82%, respectively. There were no significant differences in FACT-G, HADS, EQ-5D, or TMIG index of competence at baseline between the groups, but the mean (standard deviation) scores of PGC Morale Scale in N-SAS BC 07 and 07-Cohort groups were 10.8 (3.3) and 9.9 (3.7), respectively, with the scores being significantly greater in the N-SAS BC 07 group (p=0.020, t-test).
Conclusion: The PGC Morale Scale provides a multidimensional approach to assess the psychological state of older people. This study indicated that participation in the RCT did not affect the baseline QoL of elderly patients but suggested that the baseline QoL of the RCT participants was better than decliners.

Abstract
In this study, the (222)Rn flux density distribution at surface was estimated in East Asia with the Bayesian synthesis inversion using measurement data and a long-range atmospheric (222)Rn transport model. Surface atmospheric (222)Rn concentrations measured at Hateruma Island in January 2008 were used. The estimated (222)Rn flux densities were generally higher than the prior ones. The area-weighted mean (222)Rn flux density for East Asia in January 2008 was estimated to be 44.0 mBq m(-2) s(-1). The use of the estimated (222)Rn flux density improved the discrepancy of the model-calculated concentrations with the measurements at Hateruma Island.

Abstract
A 54-year-old woman exhibited pancreatic calcification on abdominal ultrasonography. Diagnostic imaging revealed a 20-mm mass with a 12-mm calcification in the tail of the pancreas. The mass was weakly enhanced in the early phase of contrast-enhanced CT. We performed pancreatectomy and splenectomy. Histopathological diagnosis was a nonfunctioning pancreatic neuroendocrine tumor (PNET), grade 2. This is a rare case of PNET with extensive calcification.

Abstract
OBJECTIVE Early cholecystectomy is currently the gold standard treatment for acute cholecystitis (AC). However, the acceptability and safety of this strategy remain in dispute. The aim of this study was to clarify the role of percutaneous transhepatic gallbladder aspiration (PTGBA) in the early management of AC in a single center. METHODS A total of 147 consecutive patients who were treated with PTGBA for AC from 2008 to 2012 were included in the study. The therapeutic outcomes and adverse events were evaluated. RESULTS A single PTGBA was adequate for 96 (65.3%) patients with AC. Of the remaining 51 patients, 43 (29.3%) showed an improvement after repeated PTGBA and/or percutaneous transhepatic gallbladder drainage (PTGBD), while semi-emergency cholecystectomy was needed in eight patients. Although five patients experienced adverse events (intra-abdominal hemorrhage in two, bile leakage in two and gallbladder hemorrhage in one), no patient died of treatment-related complications. Subsequently, 87 (59.2%) patients underwent cholecystectomy after PTGBA (a single PTGBA in 48 and repeated PTGBA and/or PTGBD in 39 patients). No significant differences were observed in the conversion rate from laparoscopic surgery to open cholecystectomy, operative time or intraoperative hemorrhage volume between the two groups. CONCLUSIONS The present study demonstrated the safety and acceptability of treatment with PTGBA for AC at our center. This elective treatment strategy may be a useful alternative option in the treatment of AC.

Abstract
A 54-year-old man exhibited a pancreatic mass on abdominal ultrasonography. Diagnostic imaging with endoscopic ultrasonography, computed tomography, and magnetic resonance imaging revealed that the mass comprised various internal structures and was not connected to the pancreatic duct. Over a period of 4 years and 2 months, the mass increased from 22mm to 32mm in diameter. Laparoscopic enucleation was performed, and a histopathological diagnosis of a lymphoepithelial cyst (LEC) of the pancreas was obtained. LEC is rare and seldom reported in the literature. Although it is considered to be benign, most case reports indicate that they tend to increase in size. This indicates that LEC should be carefully monitored if surgery is not performed after diagnosis.

Abstract
Abstract
Background: Afatinib, a potent irreversible ErbB Family Blocker, inhibits signaling from HER1, HER2 and HER4 dimers, and transphosphorylation of HER3. A Phase I trial was conducted to assess if afatinib 40 mg/day in combination with vinorelbine (VNR) 25 mg/m2 i.v. weekly could be safely administered to Japanese patients (pts).
Patients and methods: The safety, tolerability and pharmacokinetics (PK) of daily oral afatinib plus weekly i.v. VNR in a 28-day cycle in Japanese pts was assessed using a 3+3 design. The primary endpoint was to determine the maximum tolerated dose (MTD), based on dose-limiting toxicities (DLTs) in Cycle 1 (see Table; dose Levels 1 and 2). When the MTD was exceeded, dose Levels 2a and 3 allowed modifications of VNR dosing as used in clinical practice. Eligible pts were ≥20 years old with histologically confirmed refractory advanced/metastatic solid tumours, and an ECOG performance status (PS) 0-1. Adverse events (AEs) were documented as per NCI CTCAE v3.0. Response was assessed using RECIST 1.1, and PK parameters for both drugs were analyzed by intra-individual comparison, based on frequent blood sampling.
Results: Seventeen pts were recruited. Median age was 60 (range 40-68) years, all pts had received previous chemotherapy, and 7/9 pts with BC had received HER2-targeted therapy. No DLTs were observed at dose Level 1. When 3/5 pts developed DLTs in Cycle 1 at an afatinib dose of 40 mg in Level 2 (see Table), an intermediate cohort 2a was introduced at 20 mg/m2 VNR i.v. weekly. Tolerability at Level 2a was confirmed. With afatinib dose modification permitted, and VNR dose skipping allowed for ANC <1500/mm3, dose re-escalation to VNR 25mg/m2 i.v. weekly at Level 3 was performed to establish a recommended phase II dose. At Level 3, 7/24 planned doses of VNR were skipped due to Grade 2 and 3 neutropenia, not qualifying as DLTs. One DLT occurred in a pt with Grade 2 epigastralgia in Course 1, who required afatinib dose reduction. Overall, the most frequent drug-related AEs were leukopenia, neutropenia (100% each), diarrhea (94%), anemia (70%), stomatitis (64%) and rash (41%). Nine BC pts were treated in cohorts 2a and 3, and all experienced diarrhea, leukopenia and neutropenia. No PK drug-drug interactions between afatinib and VNR were observed. Safety and PK profiles did not appear to differ between Japanese pts and Caucasian pts in a previous Phase I study. Two pts with BC and prior trastuzumab treatment had partial responses. Tumor shrinkage was observed in four of six evaluable BC pts, but not in other tumor types.
Conclusions: Afatinib 40 mg/day plus vinorelbine 25 mg/m2/week was tolerable and showed early signs of clinical activity in Japanese pts. AEs were as expected and were managed by dose modifications of both compounds. Final data will be presented at this congress.

Abstract
OBJECTIVES The requirements of biliary stents used in the palliation of malignant biliary obstruction are a long duration of patency and minimal adverse effects. Covered self-expandable metal stents (SEMSs) have been shown to prevent tumor ingrowth, which is the most frequent complication of uncovered SEMSs. However, because they are prone to migration, the superiority of covered SEMS has yet to be convincingly demonstrated. The aim of this study was to evaluate the superiority of covered over uncovered SEMSs in the palliation of distal biliary obstruction due to unresectable pancreatic carcinoma, using both stent types with relatively low axial force and uncovered flared ends to prevent their migration. METHODS From April 2009 to December 2010, 120 patients who were admitted to 22 tertiary-care centers because of distal biliary obstruction from unresectable pancreatic carcinomas were enrolled in this prospective randomized multicenter study. Patients were randomly assigned to receive a covered or uncovered SEMS deployed at the site of the biliary stricture during endoscopic retrograde cholangiopancreatography. Stent patency time, patient survival time, patient survival time without stent dysfunction (time to stent dysfunction or patient death), cause of stent dysfunction (ingrowth, overgrowth, migration, or sludge formation), and serious adverse events were compared between covered and uncovered SEMS groups. RESULTS Patient survival time in the two groups did not significantly differ (median: 285 and 223 days, respectively; P=0.68). Patient survival time without stent dysfunction was significantly longer in the covered than in the uncovered SEMS group (median: 187 vs. 132 days; P=0.043). Stent patency was also significantly longer in the covered than in the uncovered SEMS group (mean±s.d.: 219.3±159.1 vs. 166.9±124.9 days; P=0.047). Reintervention for stent dysfunction was performed in 14 of 60 patients with covered SEMSs (23%) and in 22 of 60 patients with uncovered SEMSs (37%; P=0.08). Stent dysfunction was caused by tumor ingrowth, tumor overgrowth, and sludge formation in 0 (0%), 3 (5%), and 11 (18%) patients in the covered SEMSs group, and in 15 (25%), 2 (3%), and 6 (10%) patients in the uncovered SEMSs group, respectively. Stent migration was not observed in either group. Rates of tumor overgrowth and sludge formation did not significantly differ between the two groups, whereas the rate of tumor ingrowth was significantly lower in the covered than in the uncovered SEMS group (P<0.01). Acute pancreatitis occurred in only one patient in the covered SEMS group. Acute cholecystitis occurred in one patient in the covered SEMS group and in two patients in the uncovered SEMS group. There was no significant difference between the two groups in the incidence of serious adverse events. CONCLUSIONS By preventing tumor ingrowth and migration, covered SEMSs with an anti-migration system had a longer duration of patency than uncovered SEMSs, which recommends their use in the palliative treatment of patients with biliary obstruction due to pancreatic carcinomas.

Abstract
Topological defects can appear whenever there is some type of ordering. Its ubiquity in nature has been the subject of several studies, from early Universe to condensed matter. In this work, we investigated the annihilation dynamics of defects and antidefects in a lyotropic nematic liquid crystal (ternary mixture of potassium laurate, decanol and deionized-destillated water) using the polarized optical light microscopy technique. We analyzed Schlieren textures with topological defects produced due to a symmetry breaking in the transition of the isotropic to nematic calamitic phase after a temperature quench. As result, we obtained for the distance D between two annihilating defects (defect-antidefect pair), as a function of time t remaining for the annihilation, the scaling law D ∝ t(α), with α = 0.390 and standard deviation σ = 0.085. Our findings go in the direction to extend experimental results related to dynamics of defects in liquid crystals since only thermotropic and polymerics ones had been investigated. In addition, our results are in good quantitative agreement with previous investigations on the subject.

Abstract
We report on the dynamical behavior of defects of strength s=±1/2 in a lyotropic liquid crystal during the annihilation process. By following their positions using time-resolved polarizing microscopy technique, we present statistically significant evidence that the relative velocity between defect pairs is Gaussian distributed, antipersistent, and long-range correlated. We further show that simulations of the Lebwohl-Lasher model reproduce quite well our experimental findings.

Abstract
BACKGROUND We aimed to clarify the lifestyle factors associated with erosive esophagitis and non-erosive reflux disease (NERD) in a Japanese population. METHODS Among 886 subjects who underwent health screening, we selected, according to their scores on the FSSG (frequency scale for symptoms of gastroesophageal reflux disease; GERD) questionnaire and the findings of upper gastrointestinal endoscopy, 138 subjects with erosive esophagitis (EE), 148 subjects with NERD (absence of esophagitis, FSSG score ≥8, and acid reflux-related symptoms score ≥4), and 565 control subjects (absence of esophagitis and FSSG score ≤7). We compared clinical characteristics and various lifestyle factors in these three groups. RESULTS The lifestyle factors significantly associated with NERD compared with findings in the control group were intake of egg (odds ratio [OR] 1.89, 95% confidence interval [CI] 1.01-3.50), sleep shortage (OR 2.44, 95% CI 1.54-3.88), and strong psychological stress (OR 1.77, 95% CI 1.18-2.62). In male subjects, current smoking (OR 2.06, 95% CI 1.13-3.74; OR 1.87, 95% CI 1.09-3.20) was a significant risk factor for both NERD and EE. Moreover, alcohol >200 kcal/day (OR 3.99, 95% CI 1.03-15.55) and intake of a large quantity of food at supper (OR 7.85, 95% CI 1.66-37.05) were significant risk factors for EE in subjects with hiatal hernia. Intake of a large quantity of food at supper (OR 2.09, 95% CI 1.06-4.13) was more common in the NERD group than in the EE group. CONCLUSIONS There were differences in the associated lifestyle factors between patients with NERD and those with EE, and there was also a gender-related difference between these groups.

Abstract
Abstract
Background: Aromatase inhibitors have been shown to be superior to tamoxifen as adjuvant therapy in postmenopausal patients with hormone-responsive breast cancer. Here we report the efficacy results of long-term follow-up data from N-SAS BC 03 trial (UMIN CTRID: C000000056), in which anastrozole was compared to tamoxifen in hormone-responsive postmenopausal early breast cancer patients who had taken tamoxifen for 1—4 years out of a total of 5 years of treatment as adjuvant therapy.
Patients and methods: Out of a total of 706 recruited patients, 696 patients (tamoxifen group, n=345; anastrozole group, n=351) were used as the full analysis set for the present study. The log-rank test was used to compare the two groups in terms of disease-free survival (DFS) and relapse-free survival (RFS), Kaplan-Meier estimates were calculated. The treatment effects were estimated by Cox's proportional hazard model and were expressed as hazard ratios, with associated 95% confidence intervals (CIs).
Results: After a median follow-up of 76.1 months, (range: 1.3–110 months), the unadjusted hazard ratio was 0.87 (95%Cl 0.60–1.26; log-rank p = 0.457) for DFS and 0.77 (95%Cl 0.49–1.22; log-rank p = 0.266) for RFS, both in favor of anastrozole. The estimated hazard ratio (95%CIs) for DFS and for RFS until each time point (right censored data) was as follows: until 30 months: 0.54 (0.30–0.98) and 0.48 (0.23–0.98), until 42 months; 0.65 (0.40–1.06) and 0.53 (0.29–0.97), until 54 months: 0.77 (0.50–1.19) and 0.63 (0.37–1.06), until 66 months: 0.82 (0.55–1.24) and 0.72 (0.44–1.17), until 78 months: 0.83 (0.57–1.23) and 0.73 (0.46–1.17), respectively. The hazard ratios (95%CIs) for DFS and for RFS until 36 months were 0.72 (95%Cl 0.43–1.22) and 0.58 (95%Cl 0.30–1.12), and those after 36 months were 1.06 (95%Cl 0.62–1.81) and 0.98 (95%Cl 0.51–1.88), respectively.
Conclusion: Superior efficacy of anastrozole to tamoxifen in the Japanese population was suggested over a long-term follow-up period. It was the greatest early after switching from tamoxifen and then decreased thereafter.
