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 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)
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)
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)
BACKGROUND Breast-preserving surgery (Bp) and sentinel lymph node biopsy (SNB) are established as standard treatment for axillary lymph node-negative early breast cancer. METHODS A surgical technique using manual blunt dissection (MBD), in which use of electrocautery, an ultrasonically activated scalpel, and ligation is minimized, is described. This(More)
We evaluated the usefulness and safety of a handheld vacuum-assisted biopsy system (VACORA®) in 253 lesions suspected to be malignant. Biopsy samples were successfully obtained from 252 lesions, and no complications occurred that required other treatments during or after the biopsy. The definitive diagnosis rate using VACORA / ®was 89.3% (226/253). For 27(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. Bronchoscopy results(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)
BACKGROUND Sentinel lymph node biopsy (SNB)-oriented stepwise treatment under local anesthesia has been performed in the outpatient-ambulatory setting in patients receiving neoadjuvant therapy (NAT). We retrospectively reviewed our preliminary experience of ambulatory SNB in breast cancer patients scheduled to undergo NAT to evaluate the usefulness and(More)
