Guidance for Canadian Breast Cancer Practice: National Consensus Recommendations for the Systemic Treatment of Patients with HER2+ Breast Cancer in Both the Early and Metastatic Setting.

Human epidermal growth factor receptor 2-positive (HER2+) breast cancer is an aggressive subtype of breast cancer associated with a poor prognosis when sub-optimally treated. Recent advances include new and effective targeted therapies that have significantly improved outcomes for patients. Despite these advances, there are significant gaps across Canada, underscoring the need for evidence-based consensus guidance to inform treatment decisions.

Nighttime compression supports improved self-management of breast cancer-related lymphedema: A multicenter randomized controlled trial.

Background: Lymphedema is a prevalent long-term effect of breast cancer treatment associated with reduced quality of life. This study examined the efficacy of nighttime compression as a self-management strategy for women with chronic breast cancer-related lymphedema.

Methods: Th authors conducted a parallel 3-arm, multicenter, randomized trial.

Secondary Neuroendocrine Carcinoma Following High-Dose Radiotherapy for Head and Neck Cancer: Report of Two Cases.

Patients treated with radiation have an increased risk of developing second cancers, of which carcinomas, sarcomas, and hematological malignancies have most commonly been reported. Neuroendocrine carcinomas (NEC) are rarely reported in patients previously treated with radiation. Two patients, who had successfully undergone chemoradiotherapy for head and neck cancers at our institution, developed secondary NEC within the radiation field more than five years after the treatment.

Evaluation of three commercial progesterone receptor assays in a single tamoxifen-treated breast cancer cohort.

Estrogen receptor and progesterone receptor status are routinely assessed using immunohistochemistry assays to assist in patient prognosis and clinical management. Three commonly utilized autostainer vendors-Dako, Leica and Ventana-provide ready-to-use progesterone receptor assays; however, they have never been directly compared in a single breast cancer cohort. We looked at three immunohistochemical progesterone receptor assays, in addition to original ligand-binding assay results, in a single retrospective, tamoxifen-treated breast cancer cohort to investigate inter- and intra-observer agreement, concordance, prognostic ability and measures of test performance.

Efficacy of night-time compression for breast cancer related lymphedema (LYNC): protocol for a multi-centre, randomized controlled efficacy trial.

Background: Lymphedema is a prevalent long-term effect of breast cancer treatment that is associated with reduced quality of life. More recent observational data suggest that the addition of night-time compression to day-time use of a compression garment results in better long-term control of arm lymphedema. The primary objectives of the randomized controlled phase of the trial are to determine the efficacy of night-time compression on arm lymphedema volume maintenance and quality of life in breast cancer survivors who have completed intensive reduction treatment for their lymphedema.

A systematic comparison of three commercial estrogen receptor assays in a single clinical outcome breast cancer cohort.

Breast cancers are routinely assessed for estrogen receptor status using immunohistochemical assays to assist in patient prognosis and clinical management. Specific assays vary between laboratories, and several antibodies have been validated and recommended for clinical use. As numerous factors can influence assay performance, many laboratories have opted for ready-to-use assays using automated stainers to improve reproducibility and consistency.

Treatment of ocular metastasis with anti-VEGF: a literature review and case report.

Purpose: This is the first case report where 1.25mg intravitreal bevacizumab (IVB) correlated with choroidal mass resolution from metastatic breast cancer given concurrently with chemotherapy demonstrating, at best, disease stability in other organs.

Study Design: Case report.

Primary results of ROSE/TRIO-12, a randomized placebo-controlled phase III trial evaluating the addition of ramucirumab to first-line docetaxel chemotherapy in metastatic breast cancer.

Purpose: Currently, antiangiogenic strategies in metastatic breast cancer have demonstrated modest improvements in progression-free survival (PFS) but not improved quality or duration of survival, warranting evaluation of new agents in a placebo-controlled setting. Ramucirumab is a human immunoglobulin G1 antibody that binds vascular endothelial growth factor receptor-2 and blocks ligand-stimulated activation. The ROSE/TRIO-012 trial evaluated ramucirumab with docetaxel in unresectable, locally recurrent, or metastatic breast cancer.

A teaching model for aromatase inhibitors after tamoxifen.

Breast cancer is the most common cancer diagnosed in women. The present study evaluated the family physicians' (FPs) understanding of adjuvant hormonal therapies for an early breast cancer. FPs were invited to attend teaching workshops on this topic, which utilized a pretest, didactic and interactive teaching, and posttest format.

Phase II trial of SarCNU in malignant glioma: unexpected pulmonary toxicity with a novel nitrosourea: a phase II trial of the national cancer institute of canada clinical trials group.

Purpose: A multi-centre phase II study of SarCNU-a novel chloroethylnitrosourea (CNU)-in patients with recurrent malignant glioma to assess response rate, survival and effects of treatment.

Patients And Methods: Ten patients with histologically proven malignant glioma (seven with glioblastoma multiforme (GBM) and three with anaplastic astrocytoma) received SarCNU (860 mg/m(2)) orally on days 1, 5 and 9 on a 6 week schedule.

Results: A total of ten patients were treated on protocol before accrual was suspended for a high rate of pulmonary toxicity.

Elevated factor VIII is a risk factor for idiopathic venous thromboembolism in Canada - is it necessary to define a new upper reference range for factor VIII?

Previous studies suggest elevated factor VIII is a common, independent risk factor for venous thromboembolism (VTE); however, these studies included secondary and idiopathic VTE. We sought to explore the association between elevated factor VIII and VTE in Canadian patients with idiopathic thrombosis, and confirm the current upper factor VIII reference range was appropriate. We enrolled 300 consecutive patients with idiopathic VTE who were matched to friend controls by age, sex and ethnicity.
