The lymphocele is the main early postoperative complication of axillary clearance for breast cancer patients with rates up to 85%. The usual treatment consists of external drainage. However, this method increases the duration of hospitalization. As a result, some practitioners have abandoned drainage, allowing for ambulatory surgery. If this solution makes it possible to reduce the duration of the hospitalizations, it involves iterative punctures of the axillary hollow in case of lymphocele These punctures may be responsible for pain, hematoma or infection of the operative site. To date, no method has proved superior in terms of decreasing the incidence of lymphocele postoperatively axillary clearance. Octreotide (Sandostatin®) is a peptide, one of whose effects is to reduce the inflammation responsible for lymphoceles. The aim of the study is to inject Sandostatin® before surgery, with the aim of reducing the incidence of seroma by 50% after axillary clearance
This randomized pilot clinical trial studies arm circumference measurement with or without bioimpedance spectroscopy in finding extra lymph node fluid build up in the arm (lymphedema) early in patients with stage I-III breast cancer undergoing lymph node dissection or sentinel node biopsy. Diagnostic procedures, such as bioimpedance spectroscopy, may allow doctors to find and diagnose lymphedema earlier than arm circumference measurement alone.
Sacrifice of the intercostobrachial nerve (ICBN) during surgery is associated with development of persistent post-surgical pain (PPSP), which affects up to 60% of breast cancer surgery patients. A large, definitive trial is needed to establish whether nerve preservation techniques are effective in reducing post-surgical pain after breast cancer surgery. If the effect of ICBN preservation is consistent with observational studies, the absolute reduction of rates of persistent pain would be considerable.The primary objective is to determine the effect of ICBN preservation, versus usual care, on the prevalence and intensity of PPSP at one year after breast cancer surgery involving axillary lymph node dissection (ALND).
The contribution of automated breast ultrasound (ABUS) to the screening pathway for breast cancer is not fully understood. This prospective study aims to collect longitudinal data in women with dense breasts undergoing ABUS as a supplement to digital breast tomosynthesis (DBT). The data are intended for use in future research on the value and effectiveness of ABUS in routine clinical care. Data will be collected from eligible women who have been prescribed or have completed DBT and ABUS, screening within a 30-day window. Radiologist evaluations and, when performed, outcomes of biopsy and/or laboratory testing will be recorded. Subjects will be followed for breast cancer status and results of any diagnostic breast exams and/or treatment.
Purpose: To evaluate the preventative effects of pregabalin on pegfilgrastim-induced bone pain in cycle 1. Because granulocyte colony stimulating factor (G-CSF) receptors are found at nerve endings which modulate the pain signal, blocking this with pregabalin is theorized to prevent the occurrence of this adverse effect. Participants: Patients will be at least 18 years of age with either a diagnosis of a non-myeloid hematologic malignancy scheduled to initiate a cycle of chemotherapy that requires prophylactic use of a G-CSF, or with a diagnosis of breast cancer scheduled to initiate dose-dense doxorubicin/cyclophosphamide chemotherapy or docetaxel/cyclophosphamide that requires prophylactic use of a G-CSF. Procedures (methods): This is a randomized (1:1), single center, placebo-controlled, double blind, crossover phase II study. The primary objective is to compare the proportion of patients who have an increase in pain score of ≥3 from baseline in cycle 1 between Arm A (pregabalin) and Arm B (placebo). In consultation with the treating physician, the PI will determine what day pegfilgrastim will be initiated in each eligible, consented patient. Pregabalin or placebo will begin 4 days prior to pegfilgrastim administration, and continue for 7 additional days starting the day of pegfilgrastim administration.
This is a multicenter, open-label study in participants with triple negative breast cancer (TNBC) to study the safety, tolerability, pharmacokinetics and preliminary efficacy of SC-005. This study consists of 2 parts: Part A (dose regimen finding) followed by Part B (dose expansion).
This study evaluates ADCT-502 in patients with Advanced Solid Tumors with HER2 Expression. Patients will participate in a dose-escalation phase (Part 1) and dose expansion (Part 2). In Part 2, patients will receive the dose level identified in Part 1.
Breast cancer is the leading cause of cancer among Canadian women with nearly 26,000 new cases diagnosed each year. Fortunately, advancements in diagnostic tools and curative treatments have significantly improved overall survival. However, the development of cardiac toxicity (including asymptomatic and symptomatic heart failure) associated with use of anthracycline containing chemotherapy and targeted therapies including trastuzumab limits improvements in survival for women with breast cancer. Cardiac toxicity is a life threatening complication that leads to reduced physical functioning and quality of life. The increased risk is associated with shared risk factors among cancer and heart failure and the direct influence of cancer therapy on the cardiovascular system. Cardiac rehabilitation (CR) (including exercise training and education/counselling) has been shown to improve health outcomes, reduce heart failure related hospitalizations and modestly improve mortality among individuals with non-treatment related heart failure and may benefit women with breast cancer and treatment related cardiac toxicity (BC-CT). Therefore, this single centre, randomized control trial aims to determine if participation in an exercise based CR program can improve cardiorespiratory fitness, cardiovascular function/structure and health, and quality of life among women with BC-CT.
A 2 arm, 90 patient (45 per cohort) trial in patients with breast cancer who will be undergoing mastectomy with immediate tissue-expander reconstruction to determine whether treatment with zafirlukast (20mg PO BID) can reduce or prevent the development of capsular contracture.
The purpose of this study is to determine the safety and usefulness of oral Vitamin D supplementation in subjects with in situ carcinoma. More specifically, this study is being done to (1) understand the effect of Vitamin D supplementation on behavior of breast cancer cells and (2) the development of invasive breast cancer disease.
