Background And Purpose: Clinicians use the CTCAE scale to grade radiation dermatitis (RD) based on edema, erythema, and desquamation. The purpose of this study was to correlate the CTCAE scores with the severity of patient-reported symptoms using a skin symptom assessment (SSA) and the Radiation-Induced Skin Reaction Assessment Scale (RISRAS).
Materials And Methods: This is a secondary analysis of a randomized controlled trial involving 376 patients receiving Mepitel Film or standard-of-care for RD prophylaxis.
Background And Purpose: The study evaluated the concordance between patient-reported outcomes (PRO) and clinician-reported outcomes (CRO) of acute radiation dermatitis (RD) symptoms following adjuvant radiotherapy for early-stage and locally advanced breast cancer.
Material And Methods: This is a secondary analysis of a multi-center randomized phase 3 trial (376 patients). Ordinal logistic regression analysis was used to compare the Skin Symptom Assessment (SSA) independently reported by both patients and clinicians.
Purpose: ASCO/College of American Pathologists guidelines recommend reporting estrogen receptor (ER) and progesterone receptor (PgR) as positive with (1%-100%) staining. Statistically standardized quantitated positivity could indicate differential associations of positivity with breast cancer outcomes.
Methods: MA.
Countries face challenges in paying for new drugs. High prices are driven in part by exploding drug development costs, which, in turn, are driven by essential but excessive regulation. Burdensome regulation also delays drug development, and this can translate into thousands of life-years lost.
View Article and Find Full Text PDFPatient access to new oncology drugs in Canada is only possible after navigating multiple sequential systemic checkpoints for national regulatory approval, health technology assessment (HTA) and collective government price negotiation. These steps delay access and prevent health care providers from being able to prescribe optimal therapy. Eighteen Canadian oncology clinicians from the medicine, nursing and pharmacy professions met to develop consensus recommendations for defining reasonable government performance standards around process and timeliness to improve Canadian cancer patients' access to best care.
View Article and Find Full Text PDFPurpose: Radiation dermatitis (RD) is common in patients undergoing breast radiotherapy. Mepitel film (MF) can reduce RD, but the results from two randomized controlled trials are conflicting. We aimed to conduct a confirmatory randomized controlled trial in patients at risk of RD.

Objective: To determine the efficacy and safety of extended duration perioperative thromboprophylaxis by low molecular weight heparin when assessing disease-free survival in patients undergoing resection for colorectal cancer.
Design: Multicentre, open label, randomised controlled trial.
Settings: 12 hospitals in Quebec and Ontario, Canada, between 25 October 2011 and 31 December 2020.
The government of Canada now plans to bring into force new federal drug pricing regulations on 1 July 2022. We do not take issue with the goal of medication affordability, which is vital in healthcare the world over. Our concern is that the new guidelines are being implemented without due consideration for three major unintended consequences: regulatory changes will lower the number of clinical trials for new medications in Canada, fewer clinical trials will mean lower research and development investments, and changes will reduce patients' access to new medications.

Design: Pragmatic, cluster randomised trial.
Setting: 20 cancer centres in Ontario, Canada, allocated by covariate constrained randomisation to remote management of toxicities or routine care.
Purpose: Our institution operates a remote radiation oncology service in Northern Ontario, Canada. Since the start of the coronavirus disease 2019 pandemic, this center has operated without radiation oncologists on site owing to safety precautions, and this study seeks to understand the effect of this shift.
Methods And Materials: Departmental level data reports were used to investigate differences in metrics between April to May of 2019 and April to May 2020.
Background: This study aimed to determine the current state of oncology education in Canadian family medicine postgraduate medical education programs (FM PGME) and examine opinions regarding optimal oncology education in these programs.
Methods: A survey was designed to evaluate ideal and current oncology teaching, educational topics, objectives, and competencies in FM PGMEs. The survey was sent to Canadian family medicine (FM) residents and program directors (PDs).
Background: Patients with active cancer have an increased risk of venous thromboembolism, which results in substantial morbidity, mortality, and health care expenditures. The Khorana score (range, 0 to 6, with higher scores indicating a higher risk of venous thromboembolism) has been validated to identify patients with cancer at elevated risk for this complication and may help select those who could benefit from thromboprophylaxis.
Methods: We conducted a randomized, placebo-controlled, double-blind clinical trial assessing the efficacy and safety of apixaban (2.

The surgical treatment of localized breast cancer has become progressively less aggressive over the years. The management of the axillary lymph nodes has been modified by the introduction of sentinel lymph node biopsy. Axillary dissection can be avoided in patients with sentinel lymph node negative biopsies.
View Article and Find Full Text PDFPurpose: Exemestane, a steroidal aromatase inhibitor, reduced invasive breast cancer incidence by 65% among 4,560 postmenopausal women randomly assigned to exemestane (25 mg per day) compared with placebo in the National Cancer Institute of Canada (NCIC) Clinical Trials Group MAP.3 (Mammary Prevention 3) trial, but effects on quality of life (QOL) were not fully described.
Patients And Methods: Menopause-specific and health-related QOL were assessed by using the four Menopause-Specific Quality of Life Questionnaire (MENQOL) domains and the eight Medical Outcomes Study Short Form Health Survey (SF-36) scales at baseline, 6 months, and yearly thereafter.
Intrabony oral non-Hodgkin lymphoma (NHL) is rare. We report 2 cases of NHL of the maxilla that initially presented as apical abscesses in endodontically treated teeth. Radiographic findings were nondescript, but tissue biopsy revealed diffuse large B-cell NHL in both instances.
View Article and Find Full Text PDFPurpose: In patients with hormone-dependent postmenopausal breast cancer, standard adjuvant therapy involves 5 years of the nonsteroidal aromatase inhibitors anastrozole and letrozole. The steroidal inhibitor exemestane is partially non-cross-resistant with nonsteroidal aromatase inhibitors and is a mild androgen and could prove superior to anastrozole regarding efficacy and toxicity, specifically with less bone loss.
Patients And Methods: We designed an open-label, randomized, phase III trial of 5 years of exemestane versus anastrozole with a two-sided test of superiority to detect a 2.
Background: Osteoporosis-related fractures are a significant public health concern. Interventions that increase detection and treatment of osteoporosis are underutilized. This pragmatic randomised study was done to evaluate the impact of a multifaceted community-based care program aimed at optimizing evidence-based management in patients at risk for osteoporosis and fractures.

In subgroup analyses at 12 and 24 months, we evaluated factors (duration and type of aromatase inhibitor, tamoxifen use, age, time since menopause, body mass index, T-score) that might influence BMD at the lumbar spine, total hip, femoral neck, and 1/3 radius. Patients were randomized to receive placebo (n = 125) or 60 mg denosumab (n = 127) subcutaneously every 6 months.
View Article and Find Full Text PDFPurpose: Adjuvant aromatase inhibitor therapy is well established in postmenopausal women with hormone receptor-positive breast cancer, but such therapy is complicated by accelerated bone loss and increased fracture risk. We investigated the ability of denosumab, a fully human monoclonal antibody against receptor activator of nuclear factor-kappaB ligand, to protect against aromatase inhibitor-induced bone loss.
Patients And Methods: Eligible women with hormone receptor-positive nonmetastatic breast cancer treated with adjuvant aromatase inhibitor therapy were stratified by duration of aromatase inhibitor therapy (< or = 6 v > 6 months), received supplemental calcium and vitamin D, and were randomly assigned to receive placebo (n = 125) or subcutaneous denosumab 60 mg (n = 127) every 6 months.
