PURPOSE: Radiomics utilizes a large number of image-derived features for quantifying tumor characteristics that can in turn be correlated with response and prognosis. Unfortunately, extraction and analysis of such image-based features is subject to measurement variability and bias. The challenge for radiomics is particularly acute in Positron Emission Tomography (PET) where limited resolution, a high noise component related to the limited stochastic nature of the raw data, and the wide variety of reconstruction options confound quantitative feature metrics...

Decades of preclinical and natural history studies have highlighted the potential of fatty acid synthase (FASN) as a bona fide drug target for oncology. This review will highlight the foundational concepts upon which this perspective is built. Published studies have shown high levels of FASN in patient tumor tissues are present at later stages of disease and this overexpression predicts poor prognosis. Preclinical studies have shown that experimental overexpression of FASN in previously normal cells leads to changes that are critical for establishing a tumor phenotype...

Cancer is the leading cause of natural death in the pediatric populations of developed countries, yet cure rates are greater than 70% when a cancer is diagnosed in its early stages. Recent advances in magnetic resonance imaging methods have markedly improved diagnostic and therapeutic approaches, while avoiding the risks of ionizing radiation that are associated with most conventional radiological methods, such as computed tomography and positron emission tomography/computed tomography. The advent of whole-body magnetic resonance imaging in association with the development of metabolic- and function-based techniques has led to the use of whole-body magnetic resonance imaging for the screening, diagnosis, staging, response assessment, and post-therapeutic follow-up of children with solid sporadic tumours or those with related genetic syndromes...

Robotic-assisted surgery is a technological advancement derived from conventional laparoscopy, which facilitates the application of minimally invasive techniques for complex operations in the field of gynecological oncology. However, its introduction in gynecological cancer has been scarce in most hospitals worldwide. Most publications on robotic surgery are still retrospective or descriptive in nature. Some studies compare robotic-assisted laparoscopy with open procedures, which is a questionable analysis, because the advantages of minimally invasive surgery have been already well established...

BACKGROUND: Currently there is no reliable test to predict pathological complete response following neoadjuvant chemoradiotherapy for rectal cancer. However, there is increasing interest in using clinical complete response as a surrogate marker, allowing a subset of patients with locally advanced rectal cancer to be allocated into a "watch and wait" pathway. Little is known about the oncological safety of the "watch and wait" approach or the rate of salvage surgery in cases of tumor regrowth...

Despite advances in cancer treatment, metastasis remains today the main cause of cancer death. Local control through complete surgical resection of the primary tumor continues to be a key principle in cancer treatment. However, surgical interventions themselves lead to adverse oncologic outcomes and are associated with significantly increased rates of metastasis. Neutrophils through release of neutrophil extracellular traps (NETs) in response to infections were shown to be able to capture circulating cancer cells, and in doing so, support the development of metastatic disease...

: 145 Background: Integration of Palliative Care (PC) in oncology has been found to improve symptom distress, quality of life and survival in patients with advanced cancer. Early integration is most appropriate in the outpatient (OP) setting. However, most PC services in the U.S. do not have an OP component. Our study aims to provide a snapshot of the type of patients that are referred to this novel setting for the delivery of early PC. METHODS: We reviewed a day in the SCC to illustrate the structure and process involved in the delivery of outpatient PC...

: 244 Background: Working with cancer patients is considered inherently stressful with high levels of burnout reported. There is limited research that focuses on the multidisciplinary team as a whole; research to date tends to focus on patient death from the perspective of the bedside oncology nurse, the physician or social worker. With the focus on those disciplines individually, thereby ignoring the centrality of the multidisciplinary nature of oncology care and excluding fundamental team members who provide care and are potentially impacted by the death of the patient...

OBJECTIVES: To describe the effects of cytoreductive nephrectomy (CN) on the natural course of metastatic renal cell carcinoma (mRCC). CN appears to stabilize metastatic lesions in mRCC in a subgroup of patients and we hypothesize that systemic treatment might be deferred in these patients with stable disease after CN. SUBJECTS AND METHODS: Overall, 45 patients with mRCC who underwent CN and subsequent oncologic follow-up were included in this retrospective, single-center analysis...

: 159 Background: Approval of new oral anticancer agents (OAA) continues to rise, accounting for 75% of new oncology drugs approved so far in 2015. OAA prescriptions generated at our institution demonstrate similar growth, as the prescription volume for OAA is approximately 200% greater than it was 8 years ago. Challenges of OAA, including safe prescribing, monitoring toxicities, and assessing adherence, continue to be an obstacle to providing quality care. In recognition of these challenges, our institution employed the electronic medical record (EMR) to develop tools to enhance safe prescribing, monitoring, and follow up for patients receiving OAA...

: 205 Background: Review of treatment plans by a second radiation oncologist is an important quality indicator in radiation oncology. Peer review (PR) can improve quality of care in individual patients by detecting clinical and planning issues and recommending plan changes. This study reports the frequency and nature of these changes across all 14 radiation oncology programs (ROPs) in Ontario, Canada. METHODS: We identified all peer-reviewed curative treatment plans delivered in Ontario within a 3-month study period between Dec 2013-Nov 2014 using Cancer Care Ontario's Activity Level Reporting System, where data on treatment intent and date, disease site treated, PR status, timing of PR, and nature of recommended changes were available...

Management of testicular cancer has evolved through many breakthroughs. The decades of zeal to improve oncologic adequacy and to decrease morbidity has led to the current scientific knowledge of retroperitoneal lymph node dissection templates. Retroperitoneal lymph node dissection (RPLND) has potential for staging, prognostication and therapeutic importance in the management of testicular malignancy. RPLND has overcome limitations of current imaging which understage 30% of stage I disease and overstage 25-30% of stage II disease...

Jin Ge, Vivek Verma, Andrew Hollander, Corey Langer, Charles B Simone
Radiation recall dermatitis (RRD) is an inflammatory reaction in a previously irradiated field subsequent to the administration of pharmacologic or promoting agents. Herein, we describe a 47-year-old man with NSCLC who was treated with radiotherapy and pemetrexed-based chemotherapy three years prior to developing RRD upon resumption of pemetrexed-based chemotherapy. RRD with pemetrexed is rare and consists of five cases reported thus far. Although RRD is a rare phenomenon, it should be considered in any patient with dermatologic reactions that occur at the site of previous exposure to radiation therapy...
