Background: Invasive ductal carcinoma of the pancreas (IDCP) predominantly causes death through liver metastasis (LM) and peritoneal dissemination with local recurrence. However, whether its venous invasion is from the enlarged carcinoma accompanied by tumor growth, or from a distinct carcinoma group, for which venous invasion is facilitated by proximity to the origin, is unclear. We analyzed the correlation between LM and venous invasion in patients with small IDCP tumors. Methods: Of 388 patients who were diagnosed with IDCP, 20 (5.2%) had tumors with diameters <2 cm. The follow-up period of the 20 patients with smaller tumors was 1-24 years. Results: The small-tumor group (n = 20) included 11 men and 9 women, aged 51-80 years. Five died of liver metastasis (LM group, n = 5) and 15 patients (non-LM group, n = 15) were either alive without recurrence (n = 11) or died of peritonitis carcinomatosa following local recurrence, subarachnoid hemorrhage, primary lung cancer, or old age (n = 1 for each cause of death). The LM and non-LM groups did not significantly differ in numbers of venous invasion by the carcinoma in IDCP and non-IDCP area of the pancreas. However, median numbers of invaded veins in the area of IDCP and percentage of invaded vein/total number of vein in IDCP area were significantly higher in the LM group. Conclusion: Among patients with small IDCP tumors, the LM group showed more aggressive venous invasion by IDPC. Patients in whom ≥60% of veins were invaded by IDCP should be prepared for LM. © 2017 IAP and EPC.

Left ventricular (LV) properties in hypertension (HTN) could be deteriorated by pressure overload, especially in endocardium, resulting in hypertensive heart failure (HHF). We sought to noninvasively examine LV systolic and diastolic functions at three myocardial layers in HTN and elucidate features of HHF by speckle-tracking echocardiography (STE) with high volume rates. We examined normotensive controls (n = 54), HTN patients without LV hypertrophy (LVH) (n = 50), and HTN patients with LVH (n = 40) and HHF patients (n = 45). The HHF group was divided into two subgroups based on their LVEF (20 heart failure with preserved ejection fraction: HFpEF and 25 heart failure with reduced ejection fraction: HFrEF). LV layer systolic function was assessed by strain rate during systole. Pulmonary capillary wedge pressure (PCWP) was estimated (ePCWP) using kinetics-tracking index (KT index) that we previously reported. HTN patients with LVH had a significant deterioration of systolic and diastolic properties compared with normotensive controls in the absence of a significant reduction in LVEF. Patients with HHF had further deterioration of systolic and diastolic properties compared with HTN patients with LVH. LV strain at entire myocardium and ePCWP in HFrEF was deteriorated compared with those in HFpEF. Deterioration of LV layer SR was more typical during systole, isovolumic relaxation, and early diastole compared with control. LV dilation was independently associated with LVEF (r = −0.48, p < 0.001) and ePCWP (r = 0.47, p < 0.001), and LVH (LV mass index) was independently associated with E/e′ (r = 0.37, p = 0.025), LVEF (r = −0.44, p < 0.001), and ePCWP (r = 0.67, p < 0.001). LV layer analysis by STE could detect subtle impairments in systolic function before the deterioration of LVEF in patients with HTN. The ePCWP that was estimated using KT index was the independent factor associated with HHF. The ePCWP may be useful to noninvasively detect the early stage of HHF. © 2017 Springer Japan

There are limited studies on incidence rates of metachronous neoplastic lesions after resecting large colorectal polyps. In the present study, we analyzed metachronous lesions after endoscopic resection of colorectal polyps 20mm in size.We retrospectively analyzed consecutive patients who underwent endoscopic resection of polyps from 2006 to 2013 at two affiliated hospitals. All patients underwent at least two total colonoscopies before follow up to ensure minimal missed polyps. Only patients who had follow-up colonoscopy annually after resection were recruited. We separated patients according to size of polyp resected; there were 239 patients in the 20-mm group and 330 patients in the <20-mm group. Clinical characteristics and cumulative rates of metachronous advanced adenoma and cancer in both groups were analyzed. Advanced adenoma was defined as a neoplastic lesion 10mm in size and adenoma with a villous component.Cumulative rate of development of metachronous advanced adenoma and cancer in the 20-mm group was significantly higher than in the <20-mm group (22.9% vs. 9.5%, P<0.001) at 36months. There was also more development of small polyps 5-9mm in the 20-mm group than in the <20-mm group (45.2% vs. 28.8%, P<0.001). With respect to metachronous lesions, there were more right-sided colonic lesions in the 20-mm group than in the <20-mm group (78.8% vs. 50.0%, P=0.015).High incidence rates of development of metachronous neoplastic lesions were detected after resection of colorectal polyps 20mm in size.

Recently, the use of taxane-based regimens before anthracycline-based regimens has been shown to achieve high pathological complete response (pCR) rates in patients with breast cancer. Nanoparticle albumin-bound paclitaxel (nab-PTX) has been reported as highly effective and less toxic compared with Cremophor-based Taxol. This phase II clinical trial evaluated the safety and efficacy of preoperative neoadjuvant chemotherapy (NAC) with nab-PTX followed by an epirubicin plus cyclophosphamide (EC)-based regimen for operable breast cancer.From June 2012 to January 2014, four cycles of every-3-week (q3w) nab-PTX [plus q3w trastuzumab in cases of human epidermal growth factor 2 (HER2) positivity] followed by four cycles of q3w EC were administered to patients with operable breast cancer (stage IC-IIIA). The primary endpoint was the pCR rate (ypT0/TisypN0).A total of 55 patients were enrolled, 54 of whom received at least one nab-PTX dose. All patients underwent radical surgery after chemotherapy. The overall pCR rate was 22.2% (p=0.006). The pCR rates for patients with the luminal B, luminal/HER2, HER2-rich, and triple-negative breast cancer subtypes were 10.5, 29.4, 60, and 15.4%, respectively. Stepwise logistic regression analysis revealed only HER2 as a significant factor for pCR (odds ratio 5.603; p=0.024). The expression of secreted protein acidic and rich in cysteine showed no association with pCR. The clinical response rate was 70.4% (38/54), and the safety profile was tolerable.Preoperative NAC with nab-PTX followed by EC is effective and safe for operable breast cancer.

To examine the effects of percutaneous endoscopic gastrostomy (PEG) on quality of life (QOL) in patients with dementia.We retrospectively included 53 Japanese community and tertiary hospitals to investigate the relationship between the newly developed PEG and consecutive dementia patients with swallowing difficulty between Jan 1st 2006 and Dec 31st 2008. We set improvements in 1) the level of independent living, 2) pneumonia, 3) peroral intake as outcome measures of QOL and explored the factors associated with these improvements.Till October 31st 2010, 1,353 patients with Alzheimers dementia (33.1%), vascular dementia (61.7%), dementia with Lewy body disease (2.0%), Pick disease (0.6%) and others were followed-up for a median of 847 days (mean 805 542 days). A total of 509 deaths were observed (mortality 59%) in full-followed patients. After multivariate adjustments, improvement in the level of independent living was observed in milder dementia, or those who can live independently with someone, compared with advanced dementia, characterized by those who need care by someone: Odds Ratio (OR), 3.90, 95% confidence interval (95%CI), 1.59 - 9.39, P = 0.003. Similarly, improvement of peroral intake was noticed in milder dementia: OR, 2.69, 95%CI, 1.17 - 6.17, P = 0.02. Such significant associations were not observed in improvement of pneumonia.These results suggest that improvement of QOL after PEG insertion may be expected more in milder dementia than in advanced dementia.

Type 2 11β-hydroxysteroid dehydrogenase encoded by the HSD11B2 gene converts cortisol to inactive cortisone, and alteration in this enzymatic activity might affect glucose homeostasis by affecting circulating levels or tissue availability of glucocorticoids. We investigated the association of HSD11B2 variant with glucose homeostasis. Subjects with normal glucose tolerance (n=585), impaired glucose tolerance (n=202) and type 2 diabetes (n=355) were genotyped for a highly polymorphic CA-repeat polymorphism in the first intron of HSD11B2. Allele and genotype frequencies differed between normal and impaired glucose tolerance (P = 0.0014 and 0.0407, respectively; 4 degree of freedom) or type 2 diabetes (P = 0.0053 and 0.0078), with significant linear trends between the repeat length and the phenotype fraction. In normal subjects, total CA-repeat length was negatively correlated with fasting insulin and HOMA-β. Thus, subjects having more CA repeats are susceptible to developing abnormal glucose tolerance, whereas normal subjects carrying more CA repeats appeared to have frugal characteristics in insulin secretion. © The Japan Endocrine Society.
