Shear wave elastography is a new method of obtaining quantitative tissue elasticity data during breast ultrasound examinations. The aims of this study were (1) to determine the reproducibility of shear wave elastography (2) to correlate the elasticity values of a series of solid breast masses with histological findings and (3) to compare shear wave(More)
The association between CYP2D6 genotype and outcome in breast cancer patients treated with adjuvant tamoxifen remains controversial. We assessed the influence of comprehensive versus limited CYP2D6 genotype in the context of tamoxifen adherence and co-medication in a large cohort of 618 patients. Genotyping of 33 CYP2D6 alleles used two archival cohorts(More)
BACKGROUND The aim of this study was to assess the performance of shear wave elastography combined with BI-RADS classification of greyscale ultrasound images for benign/malignant differentiation in a large group of patients. METHODS One hundred and seventy-five consecutive patients with solid breast masses on routine ultrasonography undergoing(More)
PURPOSE To compare the histologic prognostic feature of invasive breast cancer with mean stiffness as measured with shear-wave elastography. MATERIALS AND METHODS This retrospective study was exempted from ethical committee review. Patient consent for use of images for research was obtained. The study group comprised 101 consecutive women (age range,(More)
Metformin may reduce the incidence of breast cancer and enhance response to neoadjuvant chemotherapy in diabetic women. This trial examined the effects of metformin on Ki67 and gene expression in primary breast cancer. Non-diabetic women with operable invasive breast cancer received pre-operative metformin. A pilot cohort of eight patients had core biopsy(More)
BACKGROUND A high percentage of stroma predicts poor survival in triple-negative breast cancers but is diminished in studies of unselected cases. We determined the prognostic significance of tumour-stroma ratio (TSR) in oestrogen receptor (ER)-positive male and female breast carcinomas. METHODS TSR was measured in haematoxylin and eosin-stained tissue(More)
Immunohistochemistry of primary breast cancer is routinely used to guide changes in therapy at the time of relapse. Retrospective reviews suggest that the estrogen receptor (ER), progesterone receptor (PR) and human epidermal growth factor receptor type 2 (HER2) receptor may differ between the primary and loco-regional recurrence or distant metastases. The(More)
AIMS We present the histopathological findings of a series of six cases of a benign uterine smooth muscle tumour with an unusual growth pattern. METHODS AND RESULTS All cases have the appearances of the recently described dissecting (cotyledonoid) leiomyoma. In addition, three of these lesions demonstrate the features of intravenous leiomyomatosis with(More)
AIMS HER2 status is a prognostic factor in breast carcinoma and predicts response to trastuzumab therapy. Trastuzumab is effective in the neoadjuvant, adjuvant and advanced disease settings. Knowledge of HER2 status early in the diagnostic and therapeutic process is vital for treatment planning. HER2 analysis is usually carried out by immunohistochemistry(More)
The International Tamoxifen Pharmacogenomics Consortium was established to address the controversy regarding cytochrome P450 2D6 (CYP2D6) status and clinical outcomes in tamoxifen therapy. We performed a meta-analysis on data from 4,973 tamoxifen-treated patients (12 globally distributed sites). Using strict eligibility requirements (postmenopausal women(More)
