Stereotactic body radiotherapy (SBRT) is an effective method for the treatment of localized primary lung tumors. Cyberknife, a highly accurate SBRT technique, follows the target during respiratory cycles using a metallic fiducial marker (FM) previously inserted into the lesion. Various methods have been described for the placement of an FM in peripheral pulmonary lesions; however, none of these is appropriate for mediastinal or hilar tumors. The placement of FMs in central lesions to achieve accurate SBRT is particularly relevant due to their higher mobility during respiratory and cardiac cycles...

Purpose Radiotherapy reduces the absolute risk of breast cancer mortality by a few percentage points in suitable women but can cause a second cancer or heart disease decades later. We estimated the absolute long-term risks of modern breast cancer radiotherapy. Methods First, a systematic literature review was performed of lung and heart doses in breast cancer regimens published during 2010 to 2015. Second, individual patient data meta-analyses of 40,781 women randomly assigned to breast cancer radiotherapy versus no radiotherapy in 75 trials yielded rate ratios (RRs) for second primary cancers and cause-specific mortality and excess RRs (ERRs) per Gy for incident lung cancer and cardiac mortality...

BACKGROUND: Treating patients who are critically ill with radiotherapy (RT) brings a unique set of challenges as it involves treating patients who require mechanical life support, unconventional positioning, and a multidisciplinary team approach to ensure safety. However, when the benefits of such treatment outweigh the risks, the challenges can be overcome, as demonstrated in this unique case of cardiac angiosarcoma. CASE DESCRIPTION: This is a case of a 42-year-old female with a right sided cardiac angiosarcoma who quickly developed cardiac tamponade and respiratory failure related to compression of her right heart by the tumor...

Cardiac irradiation increases the risk of coronary artery disease in patients with left-sided breast cancer. Techniques exist to reduce cardiac irradiation, but the optimum technique depends on individual patient anatomy and physiology. We investigated the correlation of delta heart volume in field (dHVIF) and sternal excursion with dose sparing in heart and left anterior descending artery (LAD) to develop quantitative predictive models for expected dose to heart and LAD. A treatment planning study was performed on 97 left-breast cancer patients who underwent whole breast radiotherapy (prescription dose = 50 Gy) under deep inspiratory breath hold (DIBH)...

A low-resource visually monitored deep inspiration breath-hold (VM-DIBH) technique was successfully implemented in our clinic to reduce cardiac dose in left-sided breast radiotherapy. In this study, we retrospectively characterized the chest wall and heart positioning accuracy of VM-DIBH using cine portal images from 42 patients. Central chest wall position from field edge and in-field maximum heart distance (MHD) were manually measured on cine images and compared to the planned positions based on the digitally reconstructed radiographs (DRRs)...

Primitive cardiac lymphoma (PCL) is a rare disease accounting for only 1-2% of primary cardiac tumors. Diffuse large B cell lymphoma is the most common type and shows a rapid progression with poor prognosis. The clinical presentation of PCL is nonspecific, and echocardiographic study is essential to the initial work-up. Magnetic resonance imaging and computed tomography scan are the methods of choice for the assessment of tumor extension. The definitive diagnosis is histopathology examination. Chemotherapy and radiotherapy represent the best treatment and should be started promptly after PCL diagnosis...

Cancer treatments can have significant cardiovascular adverse effects that can cause cardiomyopathy and heart failure with reduced survival benefit and considerable decrease in the use of antineoplastic therapy. The purpose of this study is to assess the role of TLR2 and TLR4 gene expression as an early marker for the risk of doxorubicin-induced cardiomyopathy in correlation with early diastolic dysfunction in patients treated with doxorubicin. Our study included 25 consecutive patients who received treatment with doxorubicin for hematological malignancies (leukemia, lymphomas or multiple myeloma), aged 18-65 years, with a survival probability>6 months and with left ventricular ejection fraction>50%...

BACKGROUND: Radiotherapy (RT) is frequently associated with late cardiovascular (CV) complications. The mean cardiac dose from irradiation of a left-sided breast cancer is much higher than that for a right-sided breast cancer. However, data is limited on the long-term risks of RT on CV mortality. HYPOTHESIS: RT for breast cancer is associated with long term CV mortality and left sided RT carries a greater mortality than right sided RT. METHODS: We searched PubMed, Cochrane Central, Embase, EBSCO, Web of Science, and CINAHL databases from inception through December 2015...

BACKGROUND: Clinical trials have shown that trastuzumab, a recombinant monoclonal antibody against HER2 receptor, significantly improves overall survival and disease-free survival in women with HER2-positive early breast cancer, but long-term follow-up data are needed. We report the results of comparing observation with two durations of trastuzumab treatment at a median follow-up of 11 years, for patients enrolled in the HERA (HERceptin Adjuvant) trial. METHODS: HERA (BIG 1-01) is an international, multicentre, open-label, phase 3 randomised trial of 5102 women with HER2-positive early breast cancer, who were enrolled from hospitals in 39 countries between Dec 7, 2001, and June 20, 2005...

Radiotherapy plays an important role in the treatment of early-stage Hodgkin lymphoma, but late toxicities such as cardiovascular disease and second malignancy are a major concern. Our aim was to evaluate the potential of deep inspiration breath-hold (DIBH) and intensity-modulated radiotherapy (IMRT) to reduce cardiac dose from mediastinal radiotherapy. A 24 year-old male with early-stage bulky mediastinal Hodgkin lymphoma received involved-site radiotherapy as part of a combined modality programme. Simulation was performed in free breathing (FB) and DIBH...

Hodgkin lymphoma (HL) survivors treated with radiotherapy and/or chemotherapy are known to have increased risks of heart failure (HF), but a radiation dose-response relationship has not previously been derived. A case-control study, nested in a cohort of 2,617 five-year survivors of HL diagnosed before age 51 years during 1965-1995, was conducted. Cases (n=91) had moderate or severe HF as their first cardiovascular diagnosis. Controls (n=278) were matched to cases on age, gender and HL diagnosis date. Treatment and follow-up information were abstracted from medical records...
