Pancreatic ductal adenocarcinoma (and its histological variants), also referred to as pancreatic cancer (PC) comprises 90% of exocrine pancreatic neoplasms [1]. This highly aggressive cancer is the fourth leading cause of cancer death in the USA [2]. More than 80% of patients with PC present with advanced disease that is incurable by surgery. Most tumors greater than 5 cm in size show dissemina...
A 74-year-old male was admitted to Departments of Surgery, Toyonaka Municipal Hospital (Osaka, Japan) for treatment of a pancreatic tumor. Contrast enhanced computed tomography (CT) revealed a mass with small cystic lesions in the pancreatic head and body. Fluorodeoxyglucose-positron emission tomography/CT revealed an abnormal uptake of fluorodeoxyglucose, corresponding to the mass lesions. Upp...
Herein we describe a protocol to deliver various reagents to the mouse mammary gland via intraductal injections. Localized drug delivery and knock-down of genes within the mammary epithelium has been difficult to achieve due to the lack of appropriate targeting molecules that are independent of developmental stages such as pregnancy and lactation. Herein, we describe a technique for localized d...
Surgery is standard management for patients with Mirizzi syndrome. In cases of Mirizzi syndrome type II, laparoscopic surgery is evenmore complicated because of the cholecystocholedochal fistula. Endoscopic treatment for Mirizzi syndrome is still controversial except to relieve a bile duct obstruction [1,2]. This report describes a successful endoscopic treatment for Mirizzi syndrome type II wi...
Aim and Background: it seems that population of regulatory T cells increases in many malignancies leading to suppression of effector immune responses and thereby to progression of the disease. We aimed to assess infiltration of the regulatory T cells into tumor environment in women with breast carcinoma. Methods: in a control-case study, 9 malignant tumor tissues from invasive intraductal breas...
The hypothetical multistep model of breast carcinogenesis suggests a transition from normal epithelium to invasive carcinoma via intraductal hyperplasia (without and with atypia) and in situ carcinoma. These presumptive precursor lesions are currently defined by their histological features, and their prognosis is imprecisely estimated from indirect epidemiological evidence. Cytogenetic and mole...
