We investigated the pharmacokinetics of cytotoxic anticancer agents administered under anhepatic conditions. Beagle dogs underwent either a sham operation consisting of laparotomy only (control group, n = 11) or a laparotomy and total hepatectomy under venovenous bypass (anhepatic group, n = 12). Each dog received a bolus intravenous injection of either(More)
PURPOSE To prospectively evaluate the accuracy of high-resolution (HR)-MRI as a secondary examination in women with abnormal calcifications detected on mammography. MATERIALS AND METHODS We used a 4.7-cm microscopy coil to acquire HR-MRI signal data. We examined 52 women with breast lesions preoperatively using HR-MRI and vacuum-assisted core needle(More)
BRCA1 and 53BP1 antagonistically regulate homology-directed repair (HDR) and non-homologous end-joining (NHEJ) of DNA double-strand breaks (DSB). The histone deacetylase (HDAC) inhibitor trichostatin A directly inhibits the retention of 53BP1 at DSB sites by acetylating histone H4 (H4ac), which interferes with 53BP1 binding to dimethylated histone H4 Lys20(More)
LSD1, a lysine-specific histone demethylase, is overexpressed in several types of cancers and linked to poor outcomes. In breast cancer, the significance of LSD1 overexpression is not clear. We have performed an in silico analysis to assess the relationship of LSD1 expression to clinical outcome. We demonstrate that LSD1 overexpression is a poor prognostic(More)
OBJECTIVE The purpose of this study was to describe the features of intraductal papilloma on MR ductography using a microscopic coil. CONCLUSION Intraductal papilloma appeared in most cases as a well-circumscribed mass with early enhancement and delayed washout associated with a dilated duct, predominantly showing signal hyperintensity on T1- and(More)
OBJECTIVE Because subareolar breast abscess has a high recurrence rate, a more effective imaging technique is needed to comprehensively visualize the lesions and guide surgery. We performed a high-resolution MRI technique using a microscopy coil to reveal the characteristics and extent of subareolar breast abscess. CONCLUSION High-resolution MRI has(More)
Metaplastic carcinoma of the breast is a relatively rare cancer and includes various histologic types. In this cancer, metaplastic elements are heterogeneous and sometimes mixed. We investigated, by histopathologic means, these elements and clinical implications that could indicate the clinical course (including the prognosis). Fifty-three metaplastic(More)
The results of treating 12 consecutive patients with unresectable colorectal hepatic metastases with a hepatic arterial infusion of high-dose Adriamycin, 100–120 mg/m2, using hepatic venous isolation (HVI) and charcoal hemoperfusion (CHP) are reported herein. Adriamycin was administered over 5–15 min under extracorporeal drug elimination by HVI-CHP. HVI was(More)
Exon 2 of MED12, a subunit of the transcriptional mediator complex, has been frequently mutated in uterine leiomyomas and breast fibroadenomas; however, it has been rarely mutated in other tumors. Although the mutations were also found in uterine leiomyosarcomas, the frequency was significantly lower than in uterine leiomyomas. Here, we examined the MED12(More)
The Working Group of the Japanese Society of Clinical Cytology was assembled to assess the current status of breast cytology in Japan by conducting a large-scale survey regarding the accuracy of fine-needle aspiration biopsy (FNAB) in Japan. We collected data and investigated the status of breast cytological diagnosis(More)
