OBJECTIVE In recent decades, progress in the medical management of cancer has been significant, resulting in considerable extension of survival for patients with metastatic disease. This has, in turn, led to increased attention to the optimal surgical management of bone lesions, including metastases to the spine. In addition, there has been a shift in focus toward improving quality of life and reducing hospital stay for these patients, and many minimally invasive techniques have been introduced with the aim of reducing the morbidity associated with more traditional open approaches...

Bone metastases are a common finding in oncology. They often induce pain but also fractures which impair quality of life, especially when involving weight-bearing bones. Percutaneous image-guided consolidation techniques play a major role for the management of bone metastases. Cementoplasty aims to stabilize bone and control pain by injecting acrylic cement into a weakened bone. This minimally invasive technique has proven its efficacy for bones submitted to compression forces: vertebra, acetabular roof, and condyles...

Radiation Protection in Radiology, Nuclear Medicine and Radio Oncology is of the utmost importance. Radioiodine therapy is a frequently used and effective method for the treatment of thyroid disease. Prior to each therapy the radioactivity of the [ 131I]-capsule must be determined to prevent misadministration. This leads to a significant radiation exposure to the staff. We describe an alternative method, allowing a considerable reduction of the radiation exposure. Two [ 131I]-capsules (A01=2818.5; A02=73...

The current fee-for-service system for health care reimbursement in the United Stated is argued to encourage fragmented care delivery and a lack of accountability that predisposes to insufficient focus on quality as well as unnecessary or duplicative resource utilization. Episode payment models (EPMs) seek to improve coordination by linking payments for all services related to a patient's condition or procedure, thereby improving quality and efficiency of care. The CMS Innovation Center has implemented a broadening array of EPMs...

INTRODUCTION: The high success rate in the management medulloblastoma achieved in the western world is not exactly mirrored in developing countries including India. Socio-demographic differences, health-care disparity, and lack in uniformity of care with resultant widespread variations in the clinical practice are some of the reasons that may partly explain this difference in outcomes. Patients with medulloblastoma require a multi-disciplinary team approach involving but not limited to neuro-radiology, neurosurgery; neuropathology, molecular biology, radiation oncology, pediatric medical oncology and rehabilitative services for optimizing outcomes...

INTRODUCTION: Subcentimeter non-small cell lung cancer (NSCLC) is not always an early-stage disease despite its small tumor size. We investigated the prognostic impact of such cancers based on the findings of thin-section computed tomography (CT). METHODS: We evaluated the clinicopathological features and prognosis of 328 surgically resected clinical-N0 NSCLC 1.0cm or less in size. Consolidation tumor ratio (CTR) was evaluated for all, and tumors were classified into 3 group, namely, pure-ground glass opacity (GGO) (CTR=0, n=139), part-solid (0<CTR<1...

BACKGROUND: Laparoscopic colorectal surgery has a long learning curve. Using a modular-based training programme may shorten this. Concerns with laparoscopic surgery have been oncological compromise and poor surgical outcomes when training more junior surgeons. This study aimed to compare operative and oncological outcomes between trainees undergoing a mentored training programme and a consultant trainer. METHODS: A prospective study of all elective laparoscopic colorectal resections was undertaken in a single institution...

Particle therapy facilities often require Monte Carlo (MC) simulations to overcome intrinsic limitations of analytical treatment planning systems (TPS) related to the description of the mixed radiation field and beam interaction with tissue inhomogeneities. Some of these uncertainties may affect the computation of effective dose distributions; therefore, particle therapy dedicated MC codes should provide both absorbed and biological doses. Two biophysical models are currently applied clinically in particle therapy: the Local Effect Model (LEM) and the Microdosimetric Kinetic Model (MKM)...

Despite a wide number of studies trying to define clinical, physiopathological, and neuroradiological features of posterior reversible encephalopathy syndrome (PRES), the true nature of symptoms is still not fully understood. We studied a standard cohort of 24 pediatric patients, affected by hemato-oncological diseases, with a neuroradiological diagnosis consistent with PRES identified from 2006 to 2013. Ten of them developed PRES after hematopoietic stem cell transplantation. We analyzed the sequence of clinical, radiological, and electrophysiological data...

In oncology, biomarkers that describe the characteristics of a malignancy on different levels (clinical, histological, molecular) and the patient's outcome and treatment response are increasingly integrated into the clinical routine. Extensive screening tools, "omics," offer incredible opportunities and vast amounts of data. During the last years, the field of "omics" gained a new promising partner, the "radiomics." Based on radiological imaging, multiple features can be extracted and linked to clinical, genomic, and histopathological data from other sources...

Management of resectable pancreatic adenocarcinoma continues to present a challenge due to a paucity of high-quality randomized studies. Administration of adjuvant chemotherapy is widely accepted due to the high risk of systemic spread associated with pancreatic adenocarcinoma, but the role of radiation therapy is less clear. This paper reviews literature associated with resectable pancreatic cancer to include prognostic factors to aid in the selection of patients appropriate for adjuvant therapies. The American College of Radiology Appropriateness Criteria are evidence-based guidelines for specific clinical conditions that are reviewed annually by a multidisciplinary expert panel...

In this era of precision oncology, there has been an exponential growth in the armamentarium of genomically targeted therapies and immunotherapies. Evaluating early responses to precision therapy is essential for "go" versus "no go" decisions for these molecularly targeted drugs and agents that arm the immune system. Many different response assessment criteria exist for use in solid tumors and lymphomas. We reviewed the literature using the Medline/PubMed database for keywords "response assessment" and various known response assessment criteria published up to 2016...

Many studies have showed that routine upper gastrointestinal contrast agent examinations (RCE) for testing the patency of the anastomosis after esophagectomy or the stapler line after sleeve gastrectomy cannot be recommended due to low sensitivity. However, the clinical value of RCE after gastrectomy for gastric cancer remains unclear. We have retrospectively analyzed the clinical course of 377 consecutive patients who underwent gastrectomy for gastric cancer in our institution between 2005 and 2015. To date, we have performed a RCE on the fifth postoperative day before removal of the nasogastric tube and return to oral intake...
