Role of HER2-Related Biomarkers (HER2, p95HER2, HER3, PTEN, and PIK3CA) in the Efficacy of Lapatinib plus Capecitabine in HER2-Positive Advanced Breast Cancer Refractory to Trastuzumab.

Objective: The aim of this study was to investigate the correlation between human epidermal growth factor receptor 2 (HER2)-related biomarkers and the treatment outcomes using lapatinib plus capecitabine (LC) and to evaluate the influence of the estrogen receptor (ER) status in trastuzumab-refractory HER2-positive advanced breast cancer.

Method: Eighty patients were enrolled in this study. Total HER2, p95HER2, and total HER3 expression were quantified using the VeraTag assays.

Clinical features and prognostic factors of bone metastases from colorectal cancer.

Purpose: To investigate the clinical features and prognoses of patients with diagnosed bone metastases from colorectal cancer (CRC).

Methods: This was a 16-year retrospective study of 32 patients with bone metastases secondary to CRC, who were seen at National Kokura Hospital between 1993 and 2008. The influence of clinical and pathologic variables on survival was assessed by univariate and multivariate analyses.

Inhibition of the proliferation of acquired aromatase inhibitor-resistant breast cancer cells by histone deacetylase inhibitor LBH589 (panobinostat).

Aromatase inhibitors (AIs) are important drugs for treating postmenopausal patients with hormone receptor-positive breast cancer. However, acquired resistance to AI therapies is a significant problem. Our study has revealed that the histone deacetylase inhibitor LBH589 treatment abrogated growth of AI-resistant cells in vitro and in vivo, causing cell cycle G2/M arrest and induced apoptosis.

Information-seeking experiences and decision-making roles of Japanese women with breast cancer.

Purpose: To investigate the information-seeking experiences and decision-making roles of Japanese women with breast cancer, to examine the relationship between information-seeking experiences and decision-making roles, and to explore the factors that influenced taking a more active role than the preferred role during the treatment decision-making process.

Methods: In a cross-sectional study, women with breast cancer were retrospectively administered the Control Preferences Scale and the Information-Seeking Experience Scale. The Chi-Square test was used to compare differences among individual variables in decision-making roles and information-seeking experiences.

Short-term and low-dose prednisolone administration reduces aromatase inhibitor-induced arthralgia in patients with breast cancer.

Aromatase inhibitors (AIs) are important therapeutic drugs for postmenopausal women with hormone receptor-positive breast cancer. However, adverse effects of AIs such as arthralgia have been extensively reported. We performed a joint prospective, multi-institutional investigation to find out whether a low-dose and short-term prednisolone is effective against AI-induced arthralgia in 27 patients with breast cancer.

[Docetaxel in combination with epirubicin as the first-line chemotherapy for advanced and recurrent breast cancer: a multicenter phase II study].

This study examined the efficacy and tolerability of docetaxel(DOC)in combination with epirubicin(EPI)as the first-line treatment for patients with advanced and recurrent breast cancer. A total of 56 female patients with metastatic breast cancer not previously treated for metastatic disease received DOC(60mg/m²)and EPI(60mg/m2)on day 1 every 3 weeks. The patient characteristics included a median age of 53 years.

[Adjuvant epirubicin and cyclophosphamide followed by weekly paclitaxel for Japanese women with node-positive breast cancer: a multi-institutional feasibility study].

We evaluated the feasibility of epirubicin plus cyclophosphamide(EC)followed by weekly paclitaxel (wPTX) as an adjuvant therapy for node-positive breast cancer in a variety of practice settings. Thirty-two patients received EC (twenty-two: 75, 600 mg/m(2), ten: 90, 600 mg/m(2))every 3 weeks for 4 cycles. Twenty-eight of them received wPTX for 4 cycles subsequently, which were 3 consecutive weekly administrations with a following week pause per cycle.

Corneal and conjunctival toxicity of disinfectants--assessing safety for use with ophthalmic surgical instruments.

We investigated the corneal toxicity of ortho-phthalaldehyde (Cidex OPA, Johnson and Johnson K.K.) and its predecessor glutaraldehyde (Cidex, Johnson and Johnson K.

Inhibition of inducible nitric oxide synthase prevents hepatic, but not pulmonary, injury following ischemia-reperfusion of rat liver.

The aim of this study was to investigate the contribution of inducible nitric oxide synthase (iNOS)-derived nitric oxide on the liver and lung injury following hepatic ischemia-reperfusion (I/R) using a novel and potent iNOS inhibitor, ONO-1714. Rats were subjected to 90 min of partial hepatic ischemia followed by 3, 6, 12, and 24 hr of reperfusion. Expression of iNOS mRNA peaked at 3 hr of reperfusion in the liver and lung.

A case of breast cholesterol granuloma accompanied by cancer.

Cholesterol granuloma of the breast is a very rare benign disease with clinical and imaging features that are often indistinguishable from cancer preoperatively. We report a case of breast cholesterol granuloma accompanied by cancer. The patient was a 78-year-old woman who complained of a lump in her right breast.

Role of leukotrienes on hepatic ischemia/reperfusion injury in rats.

Background: Leukotrienes (LT), composed of cysteinyl LT (cLT; LTC(4), LTD(4), and LTE(4)) and LTB(4), are potent lipid mediators enhancing the vascular permeability and recruitment of neutrophils, which are common features of hepatic ischemia/reperfusion (I/R) injury. The aim of this study was to investigate whether LT can mediate the liver and lung injuries following hepatic I/R.

Materials And Methods: Sprague-Dawley rats were subjected to 90 min of partial hepatic ischemia followed by 3, 12, and 24 h of reperfusion.

Endoscopic neck surgery: current status for thyroid and parathyroid diseases.

During the last 3 years, 59 patients underwent endoscopic neck surgery. We started the video-assisted neck surgery with the gasless skin-lifting method for benign thyroid and parathyroid diseases to avoid complications of carbon dioxide (CO2) insufflation. Hemithyroidectomy was performed for benign thyroid tumors and subtotal thyroidectomy was selected for Graves' disease.
