This paper focuses on three classes of commonly used anticancer drugs, which can cause cardiotoxicity: anthracyclines, monoclonal antibodies exemplified by trastuzumab and tyrosine kinase inhibitors. Anthracyclines can induce cardiomyocyte necrosis and fibrosis. Trastuzumab can cause cardiac stunning. The tyrosine kinase inhibitors can increase systemic arterial pressure and impair myocyte contractility. In addition, radiation therapy to the mediastinum or left chest can exacerbate the cardiotoxicity of these anticancer drugs and can also cause accelerated atherosclerosis, myocardial infarction, heart failure and arrhythmias...

Background.: The Macdonald criteria and the Response Assessment in Neuro-Oncology (RANO) criteria define radiologic parameters to classify therapeutic outcome among patients with malignant glioma and specify that clinical status must be incorporated and prioritized for overall assessment. But neither provides specific parameters to do so. We hypothesized that a standardized metric to measure neurologic function will permit more effective overall response assessment in neuro-oncology. Methods...

Esophageal cancer is a male-dominant aggressive malignancy and a leading cause of cancer-related mortality worldwide. Squamous cell carcinoma and adenocarcinoma are the two predominant histological subtypes with varying geographical and racial distribution. Globally, squamous cell carcinoma remains the most common histological type. In Western countries, however, adenocarcinoma has become the leading histological subtype, corresponding to a rise in the incidence of obesity, gastro-esophageal reflux disease and Barrett's esophagus...

Cancer represents a fast-growing challenge worldwide, and is being recognized as an emerging and critical issue in low- and middle-income countries, such most of South America. This subcontinent is unique for its geography, culture, and ethnical diversity. Most of its countries have large expanses of jungle and desert where underserved population groups including indigenous (native Indians), represent a challenge for cancer care. Many indigent patients have no access to preventive care nor early diagnosis. This results in late presentations with advanced disease and frequently incurable cancer...

The past few years have seen a significant growth of interest in the global radiation therapy (RT) crisis. Various organizations have quantified the need and are providing aid in support of addressing the shortfalls existing in many low-to-middle income countries. With the tremendous demand for new facilities, equipment, and personnel, it is very important to recognize the quality and safety challenges and to address them directly. An examination of publications on quality and safety in RT indicates a consistency in a number of the recommendations; however, these authoritative reports were generally based on input from high-resourced contexts...

A growing body of evidence supports the integration of palliative care with standard cancer treatments. In these situations, patients often experience a better quality of life, better quality of care, decreased cost, and, in some cases, improved survival with the addition of palliative care services to traditional treatment pathways. In this manuscript, we explore the integration of radiation oncology at palliative care. First, we discuss the impetus for change at Vanderbilt University and the inception of Vanderbilt's inpatient Palliative Radiation Oncology Service at Vanderbilt...
