The past few years have seen increasing support for gross total resection in the management of low-grade gliomas (LGGs), with a greater extent of resection correlated with better overall survival, progression-free survival, and time to malignant transformation. There is consistent evidence in literature supporting extent of safe resection as a good prognostic indicator as well as positively affecting seizure control, symptomatic relief in pressure symptoms, and longer progression-free and total survival. The operative goal in most LGG cases is to maximize the extent of resection for these benefits while avoiding postoperative neurologic deficits...

OBJECTIVE World Health Organization grade II gliomas are infiltrating tumors that inexorably progress to a higher grade of malignancy. However, the time to malignant transformation is quite unpredictable at the individual patient level. A wild-type isocitrate dehydrogenase (IDH-wt) molecular profile has been reported as a poor prognostic factor, with more rapid progression and a shorter survival compared with IDH-mutant tumors. Here, the oncological outcomes of a series of adult patients with IDH-wt, diffuse, WHO grade II astrocytomas (AII) who underwent resection without early adjuvant therapy were investigated...

Current multiparameter MRI protocols integrate structural, physiological, and metabolic information about cancer. Emerging techniques such as arterial spin-labeling (ASL), blood oxygen level dependent (BOLD), MR elastography, chemical exchange saturation transfer (CEST), and hyperpolarization provide new information and will likely be integrated into daily clinical practice in the near future. Furthermore, there is great interest in the study of tumor heterogeneity as a prognostic factor and in relation to resistance to treatment, and this interest is leading to the application of new methods of analysis of multiparametric protocols...

In oncology, the radiology report is a fundamental tool for communication between the radiologist, clinician, and patient. The radiology report is a document that integrates the final outcome of the radiologist's contribution to the care of the oncologic patient; therefore, the information it contains must be accurate and clear. The report must be understandable for both the patient and the clinician, so that they can use it to make the right decisions. To be effective, the information in the report must be structured, concise, accurate, and relevant...

A strong foundation in diagnostic imaging is essential to the practice of radiation oncology. This study evaluated radiology training in radiation oncology residency. An online survey was distributed to current radiation oncology residents in the USA by e-mail in 2017. Responses were summarized using frequency and percentages and compared with chi-square test and Spearman's rank correlation when appropriate. One hundred five residents completed the survey. Although most residents felt that a strong knowledge base in diagnostic radiology was moderately or extremely important (87%, n = 90/104), the majority were only somewhat confident in their radiology skills (61%, n = 63/104) and were only somewhat, minimally, or not at all satisfied with their training (79%, n = 81/103)...
