BACKGROUND Tumour-infiltrating lymphocytes (TILs) can be used to monitor the immune response, and are important in predicting treatment responses and outcomes for various types of cancer. Recently, specific TIL subsets have been reported to be clinically useful in predicting treatment responses. The CD8+/FOXP3+ TIL ratio (CFR) may be a more sensitive(More)
BACKGROUND Triple-negative breast cancer (TNBC) patients testing positive for androgen receptor (AR) expression are thought to be chemotherapy resistant, similar to other hormone receptor-positive breast cancers; however, this has not been substantially validated in the clinic. In this study, we investigated the association between chemotherapy sensitivity(More)
NADH-diaphorase and cytochrome b5 reductase activities of platelets and leucocytes, as well as erythrocytes, were found to be deficient in a patient with hereditary methaemoglobinaemia associated with moderate mental retardation and non-progressive neurological disturbance, in which hyperactive reflexes and involuntary movements were notable. In another(More)
Nanoparticle albumin-bound paclitaxel (nab-PTX, Abraxane®) does not require premedication, and it can be used for patients with alcohol intolerance. We administered nab-PTX to 31 patients with breast cancer between October 2010 and April 2013. Eighteen patients had progressive, recurring breast cancers and 13 patients had locally advanced operable breast(More)
INTRODUCTION Current guidelines recommend completion axillary lymph node dissection (cALND) in case of a sentinel lymph node (SN) metastasis larger than 2 mm (macrometastasis). However in many patients of those, the non-sentinel lymph nodes (NSN) contain no further metastasis, indicating that axillary lymph node dissection provides no benefit. To identify(More)
BACKGROUND Tumour cells and stromal cells interact in the tumour microenvironment; moreover, stromal cells can acquire abnormalities that contribute to tumour progression. However, interactions between lymphatic endothelial cells (LECs) and tumour cells are largely unexamined. In this study, we aimed to determine whether tumour-specific LECs inhabit the(More)
INTRODUCTION Patients with four or more axillary lymph node metastases have benefited from postmastectomy radiotherapy to the supraclavicular region. However, when metastatic sentinel nodes (SNs) are present, information regarding the total number of node metastases cannot be obtained if axillary lymph node dissection (ALND) is omitted from the treatment(More)
Anaplastic thyroid cancer (ATC) is a rare malignancy that progresses extremely aggressively and often results in dismal prognosis. We investigated the efficacy of inhibiting the activated RAS/RAF/MEK pathway in ATC cells aiming to clarify the mechanism of effect and resistance. Four human ATC cell lines (ACT-1, OCUT-2, OCUT-4 and OCUT-6) were used. OCUT-4(More)
A 74 -year-old man was hospitalized for chest pain. Chest computed tomography showed a 4 × 8 cm-sized tumor pressing on the left pectoralis major muscle. Subsequent imaging showed progression of the tumor along with rib erosion and intrapleural invasion. The patient was admitted to our hospital for a follow-up examination of the tumor.
