LESSONS LEARNED: Due to evolving imaging criteria in brain tumors and variation in magnetic resonance imaging evaluation, it is not ideal to use response rate as a primary objective. Future studies involving antiangiogenic agents should use overall survival.Disease-expected toxicities should be considered when defining the clinical significance of an adverse event. For example, vascular thromboembolic events are common in brain tumor patients and should not be attributed to the study drug in the safety analysis...

OBJECTIVE: Randomized studies have not demonstrated a survival benefit of routine lymph node dissection in early-stage endometrial cancer. Many surgeons nevertheless perform lymph node dissection in all patients with early-stage endometrial cancer. This study aimed to ascertain the survival outcomes of very low-risk endometrial cancer patients (by the Korean Gynecologic Oncology Group [KGOG] criteria) who did not undergo lymph node dissection. MATERIALS AND METHODS: Medical records of 156 consecutive patients who underwent surgical staging without lymph node dissection were collected from 10 institutions...

Systemic or locoregionally administered alpha-particle emitters are highly potent therapeutic agents used in oncology that are fundamentally novel in their mechanism and, most likely, overcome radiation resistance as the alpha particles emitted have a short range and a high linear energy transfer. The use of alpha emitters in a clinic environment requires extra measures with respect to imaging, dosimetry, and radiation protection. This is shown for the example of 223 Ra dichloride therapy. After intravenous injection, 223 Ra leaves the blood and is taken up rapidly in bone and bone metastases; it is mainly excreted via the intestinal tract...

Radiomics utilizes high-dimensional imaging data to discover the association with diagnostic, prognostic, predictive endpoint or radiogenomics. It is an emerging field of study that potentially depicts the intratumoral heterogeneity from quantitative and classified high-throughput data. The radiomics approach has an analytic pipeline where the imaging features are extracted, processed and analyzed. At this point, special data handling is essential because it faces issues of a high-dimensional biomarker compared to a single biomarker approach...

BACKGROUND: The histological classification or subtyping of non-small cell lung cancer is essential for systematic therapy decisions. Differentiating between the two main subtypes of pulmonary adenocarcinoma and squamous cell carcinoma highlights the considerable differences that exist in the prognosis of patient outcomes. Physicians rely on a pathological analysis to reveal these phenotypic variations that requires invasive methods, such as biopsy and resection sample, but almost 70% of tumors are unresectable at the point of diagnosis...

PURPOSE: Colectomy for cancer in obese patients is technically challenging and may be associated with worse outcomes. Whether visceral obesity, as measured on computed tomography, is a better predictor of complication than body mass index (BMI) or determines long-term oncologic outcomes has not been well characterized. This study examines the association between derived anthropometrics and postoperative complication and long-term oncologic outcomes. METHODS: Retrospective review of patients undergoing elective colectomy for cancer at a single tertiary-care center from 2010 to 2016...

Imaging techniques can establish a structural, physiological, and molecular phenotype for cancer, which helps enable accurate diagnosis and personalized treatment. In recent years, various imaging techniques that make it possible to study the functional characteristics of tumors quantitatively and reproducibly have been introduced and have become established in routine clinical practice. Perfusion studies enable us to estimate the microcirculation as well as tumor angiogenesis and permeability using ultrafast dynamic acquisitions with ultrasound, computed tomography, or magnetic resonance (MR) imaging...

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...

Urinary diversions are surgical procedures that reconstruct the lower urinary tract following cystectomy. The 2 common surgical approaches are based on the continence status of the urinary tract. Incontinent diversions have continuous urine drainage through a cutaneous stoma, whereas continent diversions offer the patient the ability to self-void either via stoma catheterization or with the patient's own urethra. Given the large number of diversion procedures available, postsurgical anatomy may be complex. Multiple imaging modalities can be used to assess the postprocedural anatomy, potential complications, and for on-going oncologic monitoring...

Intraoperative neurosurgical histopathologic diagnoses rely on evaluation of rapid tissue preparations such as frozen sections and smears with conventional light microscopy. Though useful, these techniques are time consuming and therefore unable to provide real-time intraoperative feedback. In vivo molecular imaging techniques are emerging as novel methods for generating real-time diagnostic histopathologic images of tumors and their surrounding tissues. These imaging techniques rely on contrast generated by exogenous fluorescent dyes, autofluorescence of endogenous molecules, fluorescence decay of excited molecules, or light scattering...

Cardiovascular (CV) toxicity associated with anti-cancer treatment is commonly encountered and raises critical problems that often result in serious morbidity or mortality. Most cardiac toxicities are related to the cumulative dose of chemotherapy; however, the type of chemotherapy, concomitant agents, and/or conventional CV risk factors have been frequently implicated in CV toxicity. Approximately half of the patients exhibiting CV toxicity receive an anthracycline-based regimen. Therefore, serologic biomarkers or cardiac imagings are important during anti-cancer treatment for early detection and the decision of appropriate management of cardiotoxicity...

BACKGROUND In cases of celiac axis occlusion requiring pancreaticoduodenectomy for malignancy, both oncologic curability and control of hepatic arterial flow must be considered, but the operative strategy is undeveloped. CASE REPORT Case 1: A 74-year-old man was diagnosed with hilar cholangiocarcinoma with celiac axis stenosis. The collateral from the superior mesenteric artery ran through the pancreas head but no invasion was observed in preoperative imaging. Hepatopancreatoduodenectomy with preservation of a collateral was performed...

Surgical partial nephrectomy is still considered as the "gold standard" for the definitive management of small malignant renal masses, whereas treatment with image-guided percutaneous ablation is still mainly reserved for those patients who cannot undergo nephron-sparing surgical resection due to advanced age, underlying comorbidities or compromised renal function. Nonetheless, the recent evidence that underlines the long-term oncological equipoise of percutaneous ablation methods with surgical resection in combination with the reduced complication rate and cost supports the use of an image-guided minimally invasive approach as a first-line treatment...
