Active clinical trials for "Cardiotoxicity"

All patients enrolled in the study will have to be treated with a chemo immunotherapy scheme R-CHOP with doxorubicin, with doxorubicin analogue or non pegylated liposomal anthracycline (R-COMP; Sec. 648 DM) administered every 21 days for 6 cycles. In unfavourable patients (stage II-IV) are allowed 2 additional cycles of rituximab at the end of the 6 cycles of R-CHOP.

Over 50% of the more than 270,000 childhood cancer survivors in the U.S. have been treated with anthracyclines and thus are at risk of developing cardiotoxicity. The impact of exercise training on LV structure has been extensively studied. Left ventricular hypertrophy and cardiac chamber enlargement with the accompanying ability to generate a large stroke volume are direct results of exercise training. Aerobic exercise therapy offers a non-pharmacological mechanism to modulate multiple gene expression pathways that may promote cardiac remodeling. No prior studies have investigated the efficacy of aerobic exercise in the prevention or treatment of anthracycline-induced cardiotoxicity. We hypothesize that exercise intervention leads to a reverse in adverse cardiac remodeling with improvement of global and regional myocardial function in patients exposed to anthracycline.

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.

Breast cancer is the most common cancer amongst Canadian women. 15-20% of early breast cancers have high levels of a protein called HER2 which is associated with worse survival. Treatment of these patients with anthracyclines followed by trastuzumab (which targets HER2) improves survival. Unfortunately, these medications together can cause heart muscle injury resulting in heart dysfunction or failure in about 14% and 3.6% of the patients, respectively. Once heart failure (HF) occurs, about 60% of patients will not live past 2 years. Studies have suggested that patients with heart injury caused by anthracyclines may be more likely to develop HF with addition of trastuzumab. Therefore tests to find early heart injury after anthracyclines may allow doctors to start heart protective medications with the hope of preventing HF. Also, animal and small patient studies have shown that an increase in the water levels of the heart muscle (edema) may be an early sign of heart injury from anthracyclines. Cardiac MRI is a unique technique that has been shown to detect edema in various heart diseases. The investigators will test the theory that, in women receiving treatment for breast cancer, heart edema detected by MRI at the end of anthracyclines will identify patients who will later develop heart dysfunction. MRI studies with novel techniques will be done pre-therapy, after anthracyclines, during herceptin, and at end of all therapy. The investigators will compare patients with and without heart dysfunction to test if patients with heart dysfunction are more likely to have edema after anthracyclines. Ultimately the investigators hope to use cardiac MRI to identify high risk patients and study various heart protective medications to prevent HF. This will improve the personal health of cancer patients by allowing them to live free of heart disease after their cancer therapy. Ultimately at a population level this will allow doctors to provide care that can be uniquely designed for each patient based on their individual risk. The first 136 patients enrolled are included in the first part of the study, named EMBRACE-MRI 1. Enrollment for this part of the study is complete. The remaining 44 patients will be enrolled into EMBRACE-MRI 2, which includes slight differences in obtaining sequences in MRI imaging.

RATIONALE: Drugs used in chemotherapy use different ways to stop tumor cells from dividing so they stop growing or die. Giving chemotherapy before surgery may shrink the tumor so that it can be removed during surgery. Giving chemotherapy after surgery may kill more tumor cells. PURPOSE: This phase II trial is studying how well giving chemotherapy before and after surgery works in treating patients with osteosarcoma.

The purpose of this study is to to examine the effects of atorvastatin, a type of statin, on changes to the heart among women undergoing breast cancer treatment. Atorvastatin may reduce or eliminate the harmful effects of chemotherapy treatment to the heart tissue of breast cancer patients.

The purpose of the present study is to evaluate cardiotoxicity during re-challenge of a different modality of fluoropyrimidine (primary end-point S-1 and secondary any other fluoropyrimidine) after having perceived cardiotoxicity with a fluoropyrimidine based regimen previously. The patient population is being treated for solid tumors.

An observational, prospective study to describe the rates and predictors of cardiovascular events in patients with acute leukemia.

The aim of this study is to compare CHOP versus CEOP-induced cardiotoxicity in patients with aggressive B-cell lymphoma. The hypothesis is epirubicin is associated with less cardiotoxicity without compromising the efficacy.

Diffuse large B-cell lymphoma is the most prevalent subgroup within malignant lymphoma. Clinical benefit has been shown for the treatment with cyclophosphamide, doxorubicin, vincristin and prednisolone (CHOP regimen); this could be further improved recently by the addition of rituximab (R-CHOP), a monoclonal antibody. Improved response and overall survival rates make it necessary to evaluate late toxicities of the therapy regimens. Cardiotoxicity is a known risk factor of specific chemotherapies, with 7% patients being affected if doxorubicin cumulative doses are under 550mg/sqm. Retrospective data analyses indicate that this incidence of cardiotoxicity may be higher under combination chemotherapy. Liposomal doxorubicin has been shown to have lower cardiotoxic effects and at the same time equivalent or higher efficacy compared to conventional doxorubicin. The aim of this study is to evaluate alternative regimens for the treatment of diffuse large B-cell lymphoma, substituting liposomal doxorubicin (R-COMP) for conventional doxorubicin (R-CHOP).
