[A Case of Postoperative Pulmonary Metastasis of Breast Cancer with Complete Response by Abemaciclib plus Fulvestrant Therapy].

A 66-year-old woman underwent total mastectomy with level Ⅰ and Ⅱ axillary lymph node dissection for right breast cancer in July 2007. The pathology results indicated the presence of T2N0M0 invasive ductal carcinoma(tubule forming type), that was estrogen receptor-positive and human epidermal growth factor 2-negative. She received postoperative adjuvant therapy with oral anastrozole(ANA)for 5 years.

[Primary Peritoneal Carcinoma with Long Term Survival-A Case Report].

A 62-year-old woman underwent upper endoscopy in January 2009 to reveal the presence of an extrinsic compression measuring approximately 3 cm in the anterior wall of the gastric antrum. Further examinations suggested that it was caused by peritoneal cancer of an unknown origin; thus, staging laparoscopy was performed in May 2009. Multiple white nodules of varying sizes were found scattered throughout the right upper quadrant of the abdomen and the right abdomen.

Novel compound heterozygous EPG5 mutations consisted with a missense mutation and a microduplication in the exon 1 region identified in a Japanese patient with Vici syndrome.

Vici syndrome is a rare, autosomal recessive, multisystem disorder, characterized by agenesis of the corpus callosum, cataracts, psychomotor delay, cardiomyopathy, hypopigmentation, and recurrent infections. Mutations in the ectopic P-granules autophagy protein 5 homolog gene (EPG5), which encodes a key autophagy regulator, are responsible for this syndrome. A 3-year-old Japanese girl manifesting similar symptoms to those found in patients with Vici syndrome showed intractable diarrhea, rather than immunodeficiency.

[A Case of Recurrent Breast Cancer with Complete Response to Eribulin Monotherapy after Bevacizumab plus Paclitaxel Combination Therapy].

A 65-year-old woman underwent mastectomy and dissection of a level I axillary lymph node in January 2002 for left breast cancer. The diagnosis was T1N0M0 scirrhous carcinoma that was estrogen receptor-positive, progesterone receptorpositive, and human epidermal growth factor receptor 2-negative. After 3 years 10 months, during which the patient underwent adjuvant therapy with oral aromatase inhibitors, she developed bilateral multiple lung metastases.

Poorly differentiated ductal adenocarcinoma of the pancreas with rapid progression in a young man.

Pancreatic cancer in young adults is very rare. We report a case of young-onset poorly differentiated pancreatic ductal adenocarcinoma with rapid progression and poor prognosis in a 31-year-old Japanese man with no obvious family history of malignancy. Preoperative examinations revealed a mass lesion in the body of the pancreas, accompanied by a slightly dilated main pancreatic duct distal to the mass lesion.

Early and Delayed Induction of DSBs by Nontargeted Effects in ICR Mouse Lymphocytes after In Vivo X Irradiation.

The goal of this study was to determine whether in vivo X irradiation induces nontargeted effects, such as delayed effects and bystander effects in ICR mouse lymphocytes. We first examined the generation of DNA double-strand breaks (DSBs) in lymphocytes, isolated from ICR mice exposed to 1 Gy X irradiation, by enumeration of p53 binding protein 1 (53BP1) foci, and observed that the number of 53BP1 foci reached their maximum 3 days postirradiation and decreased to background level 30 days postirradiation. However, the number of 53BP1 foci was significantly increased in lymphocytes isolated from ICR mice 90-365 days postirradiation.

The usefulness of a questionnaire to evaluate daily living performance in psychiatric inpatients: results of cross-sectional and follow-up studies.

The purpose of this research was to study the usefulness of daily living performance scores (DLPS) in order to indicate the capabilities of inpatients at psychiatric hospitals in performing activities of daily living (ADL). A cross-sectional study was conducted on 44 subjects who were inpatients at psychiatric hospitals in Japan and who responded to a questionnaire about daily living performance. A follow-up survey was conducted 9 months later on 43 patients.

Pancreatic schwannoma: Case report and an updated 30-year review of the literature yielding 47 cases.

Pancreatic schwannomas are rare neoplasms. Authors briefly describe a 64-year-old female patient with cystic pancreatic schwannoma mimicking other cystic tumors and review the literature. Databases for PubMed were searched for English-language articles from 1980 to 2010 using a list of keywords, as well as references from review articles.

Clinicopathologic study of the MIB-1 labeling index (Ki67) and postoperative prognosis for intraductal papillary mucinous neoplasms and ordinary ductal adenocarcinoma.

Objectives: Intraductal papillary mucinous neoplasms (IPMNs) are pathologically classified as IPMN with low- or intermediate-grade dysplasia, IPMN with high-grade dysplasia, and IPMN with an associated invasive carcinoma. A stepwise carcinogenic pathway has been considered for IPMN. However, it is not obvious when surgical resection should be performed for IPMN.

Volumetric and morphological analysis of intraductal papillary mucinous neoplasm of the pancreas using computed tomography and magnetic resonance imaging.

Objective: The purpose of this study was to predict the malignancy of intraductal papillary mucinous neoplasm (IPMN) based on data obtained by computed tomography and magnetic resonance imaging.

Methods: Sixty-nine patients with IPMN underwent computed tomography, magnetic resonance imaging, and surgery. The tumors were classified pathologically as IPMN (adenoma), IPMN (in situ carcinoma), and invasive carcinoma derived from IPMN, and analyzed morphologically for the following characteristics: tumor size, main pancreatic duct (MPD) diameter, tumor area, MPD area, tumor volume, MPD volume, and intraductal volume (tumors volume + MPD volume).

A pancreatobiliary-type carcinoma in situ at the periphery of a mural nodule developed from a gastric adenoma in an intraductal papillary mucinous neoplasm.

We report a rare case of an intraductal papillary mucinous neoplasm (IPMN) with a pancreatobiliary-type carcinoma in situ (CIS) that originated around a mural nodule formed in a gastric-type adenoma. A 64-year-old man was admitted to our hospital in December 2001 for dilation of the main pancreatic duct, detected on abdominal ultrasonography. Branch-duct-type IPMN (diameter 25 mm) was diagnosed, and because mural nodules were absent, the patient was annually followed up for 5 years.

Clinicopathological significance of cell cycle regulatory factors and differentiation-related factors in pancreatic neoplasms.

Objectives: The aim of the present study was to compare the expression levels of the cyclins and the differentiation-related factors in pancreatic neoplasms.

Methods: The expression levels of cyclins A and B1, E1A-like inhibitor of differentiation 1 (EID-1), p300, 3'-5'-cyclic sdenosine monophosphate response element binding protein (CREB) binding protein (CBP), and acetylated histone H3 (AcH3) in ordinary ductal carcinoma (ODC) and intraductal papillary mucinous neoplasms (IPMNs) of the pancreas were investigated.

Results: More cells positive for cyclin A and EID-1 were present in the ODC than in the IPMNs.

Intraductal papillary-mucinous neoplasms of the gastric and intestinal types may have less malignant potential than the pancreatobiliary type.

Objectives: Intraductal papillary-mucinous neoplasms (IPMNs) of the pancreas are classified into 4 types--gastric, intestinal, pancreatobiliary, and oncocytic--on the basis of their morphology and immunohistochemistry. We classified IPMNs at our institute and used this classification to determine the clinicopathological features, prognosis, and malignant potential of the 4 types.

Methods: Sixty-one patients with IPMN who underwent surgery between 2000 and 2007 were evaluated retrospectively.

Evaluation of performance status of daily living activities and of the future risk of falls in the non-handicapped, community-dwelling elderly.

Objectives: There is a growing need to evaluate the performance status of the activities of daily living (ADL) of the elderly in the rapidly aging Japanese society. The purpose of this study was to verify the usefulness of our new scoring sheet for assessing present ADL status and to clarify whether or not the assessed ADL status can predict the future risk of adverse conditions related to falls.

Methods: The validation study was performed using 116 non-handicapped community-dwelling Japanese elderly at least 60 years of age.

Intrahepatic micrometastases around liver metastases from gastric cancer.

Background/purpose: We aimed to clarify the association between the presence of micrometastases around liver metastases from gastric cancer and the results of hepatic resection. In addition, we investigated the influence of E-cadherin and matrix metalloproteinase (MMP)-7 expression on the development of micrometastases.

Methods: Micrometastases around liver metastases were examined microscopically in 31 metastatic liver tumor specimens resected from 17 patients who had undergone hepatic resection for liver metastases from gastric cancer.

Analysis of c-kit protein expression in pancreatic neoplasms and its implication for prognosis.

Background/aims: To evaluate the expression and role of c-kit protein in the neoplasia of pancreatic neoplasms and its relationship to prognosis in invasive ductal carcinoma (IDC) of the pancreas.

Methodology: The immunohistochemical expression of c-kit protein was studied in normal pancreatic tissues, intraductal papillary-mucinous neoplasms of the pancreas (IPMN), mucinous cystic neoplasm of the pancreas (MCN), and IDC of the pancreas. The immunoreactive score (IRS) of c-kit protein expression was examined in normal pancreatic ductal cells, neoplastic cells, and pancreatic endocrine cells.

Neuroendocrine carcinoma of the stomach with peripancreatic lymph node metastases successfully treated with pancreaticoduodenectomy.

Neuroendocrine carcinoma of the stomach is an uncommon tumor, usually associated with highly malignant biological behavior and extremely poor prognosis. In this report, we described a case of advanced neuroendocrine carcinoma of the stomach with the peripancreatic lymph node metastases which was treated with pancreaticoduodenectomy with extended lymphadenectomy. The patient was admitted to our hospital for anemia.

The significance of intraoperative Doppler ultrasonography in evaluating hepatic arterial flow when assessing the indications for the Appleby procedure for pancreatic body cancer.

Background/purpose: The Appleby procedure has been used in the surgical treatment of advanced gastric cancer. This procedure consists of a combined resection of the whole of the stomach, the body and tail of the pancreas, and the spleen, as well as resection of the celiac artery. This procedure can also be used for operative resection of cancer of the body of the pancreas.

Histopathological study of intraductal papillary mucinous tumor of the pancreas: special reference to the roles of Survivin and p53 in tumorigenesis of IPMT.

Aim: In this study, we investigated the tissue expression of Survivin, p53, and Bcl-2 in intraductal papillary-mucinous tumor (IPMT) of the pancreas to identify their roles in tumorigenesis of IPMT, and examined their correlations with tumor cell apoptosis and proliferation in IPMT. The diagnostic values of the expression of Survivin, p53, and Bcl-2 and the apoptotic index (AI) and Ki-67 labeling index (Ki-67 LI) in IPMT were also examined.

Methods: Twenty-two lesions from 17 patients with IPMT, including 12 benign (IPMT Adenoma) and 10 malignant (IPMT Carcinoma In Situ [CIS] (n = 4) and Invasive IPMT (n = 6) lesions, were immunostained for Survivin, p53, Bcl-2 and Ki-67.
