BACKGROUND: Rhabdoid tumors (RTs) of the liver are rare, aggressive and nonsecreting malignancies occurring mainly during the first year of life. Definition of RT relies on characteristic morphology and on the inactivation of the SMARCB1 tumor suppressor gene. The aim of this study was to analyze clinical data, treatments and outcomes in our patients. PATIENTS AND METHODS: 6 cases of patients treated in our institution for RT of the liver between January 2007 and January 2015 are reported...

The purpose of this study is to evaluate the dosimetric impact of the margin on the multileaf collimator-based dynamic tumor tracking plan. Furthermore, an equivalent setup margin (EM) of the tracking plan was determined according to the gated plan. A 4-dimensional extended cardiac-torso was used to create 9 digital phantom datasets of different tumor diameters (TDs) of 1, 3, and 5 cm and motion ranges (MRs) of 1, 2, and 3 cm. For each dataset, respiratory gating (30% to 70% phase) and tumor tracking treatment plans were prepared using 8-field 3-dimensional conformal radiation therapy by 4-dimensional dose calculation...

INTRODUCTION: The purpose of this study was to determine the impact of radiation dose to substructures of the heart in lung stereotactic body radiotherapy (SBRT) patients on non-cancer-related deaths. METHODS: Patients treated with lung SBRT at a single institution from 2005 to 2013 were included. The heart and its substructures were contoured, and dose was calculated including mean, max, and max 10 cc dose. Clinical variables including stage, histology, age, gender, Charlson comorbidity index (CCI), preexisting cardiac disease, pulmonary function (forced expiratory volume in 1 second, diffusion capacity), and smoking status were explored for association with non-cancer-related deaths in univariable (UVA) and multivariable (MVA) analyses...

Cardiac metastases from sarcoma are uncommon. Due to their rarity there is not a standard of care. However, complete cardiac metastases resection is the best option but most of patients has widespread disease. In these patients palliative radiotherapy (RT) might improve symptoms and prevent further cardiac function decline. Here we present the case of a symptomatic 30-year-old woman with spindle cell sarcoma metastasis of right ventriculum and widespread disease. The patient received radiotherapy to the heart with palliative intent...

The aim of this European Heart Rhythm Association (EHRA) survey was to evaluate clinical practice regarding cardio-oncologic patients, with special focus on patients with cardiac implantable electronic devices (CIEDs) planned for anticancer radiotherapy (RT), among members of the EHRA electrophysiology research network. Of the 36 responding centres, 89% managed patients who were diagnosed or treated oncologically, and this diagnosis affected 1-5% of cardiovascular patients in majority of centres (57%). The main side effects of anticancer therapy in patients treated by cardiologists were thromboembolic complications and left ventricular dysfunction (both reported as 'frequent' by 43% of the centres)...

BACKGROUND: Advances in radiotherapy (RT) have allowed an increased proportion of lung cancer patients to be treated curatively. High doses delivered to critical thoracic organs can result in excess mortality with tolerance doses poorly defined. This work presents a novel method of identifying anatomical dose-sensitive regions within the thorax. METHODS: A high-resolution, normal-tissue dosimetric analysis was performed to identify regions in the heart that correlate with poorer survival...

Breast carcinoma is the most common invasive cancer in women worldwide. It metastasizes commonly to bone, lungs, regional lymph nodes and brain. Cardiac metastasis of lung and breast cancers is a known but rare complication of advanced disease with tumour metastasising to pericardium via the locoregional lymphatic system. Here we present a case of 59-year-old female presenting with right upper limb oedema, facial puffiness and features of Superior Vena Cava (SVC) syndrome 15 years after mastectomy and adjuvant chemotherapy, radiotherapy for carcinoma of the right breast...

REVIEW
Vivek Verma, Charles B Simone, Maria Werner-Wasik
For patients with unresectable locally-advanced non-small cell lung cancer (LA-NSCLC), concurrent chemoradiotherapy improves overall survival as compared to sequential chemotherapy and radiation therapy, but is associated with higher rates of toxicities. Acute, clinically significant esophagitis or pneumonitis can occur in one in five patients. The risks of esophagitis and pneumonitis can impact the decision to deliver concurrent therapy and limit the total dose of radiation therapy that is delivered. Hematologic toxicities and emesis are common toxicities from systemic therapies for LA-NSCLC and can result in delaying chemotherapy dosing or chemotherapy dose reductions...

Primary testicular lymphoma (PTL) is a rare but aggressive disease. Although most patients present in the early stage, their prognosis is poor. Similar with PTL, cardiac lymphoma is also an uncommon disease characterized by its aggressive clinical course and poor prognosis. We herein report an extremely rare case of advanced stage PTL with cardiac involvement, treated by high-dose chemotherapy with autologous stem cell transplantation (HDT-ASCT) followed by systemic chemotherapy, prophylactic intrathecal methotrexate (IT-MTX), and radiotherapy...

Radiation therapy of breast cancer, Hodgkin lymphoma, lung cancer and others thoracic irradiations induce an ionizing radiation dose to the heart. Irradiation of the heart, associated with patient cardiovascular risk and cancer treatment-induced cardiotoxicity, increase cardiovascular mortality. The long survival after breast or Hodgkin lymphoma irradiation requires watching carefully late treatment toxicity. The over-risk of cardiac events is related to the dose received by the heart and the irradiated cardiac volume...

REVIEW
Charles B Simone
Thoracic malignancies are often a difficult group of tumors to treat definitively as the radiation doses needed to achieve a high probability for tumor control are often associated with high rates of radiation-induced toxicities. The lungs are particularly radiosensitive and are susceptible to radiation pneumonitis in the acute and subacute settings and pulmonary fibrosis in the late setting. Acute esophagitis is common and affects patient quality of life. Beyond acute pericarditis, late cardiac toxicities are increasingly being recognized as clinically relevant when delivering thoracic radiotherapy and can affect overall survival...

To date, five cancer treatment modalities have been defined. The three traditional modalities of cancer treatment are surgery, radiotherapy, and conventional chemotherapy, and the two modern modalities include molecularly targeted therapy (the fourth modality) and immunotherapy (the fifth modality). The cardiotoxicity associated with conventional chemotherapy and radiotherapy is well known. Similar adverse cardiac events are resurging with the fourth modality. Aside from the conventional and newer targeted agents, even the most newly developed, immune-based therapeutic modalities of anticancer treatment (the fifth modality), e...
