A phase I, dose-finding study of sorafenib in combination with gemcitabine and radiation therapy in patients with unresectable pancreatic adenocarcinoma: a Grupo Español Multidisciplinario en Cáncer Digestivo (GEMCAD) study.

Hide Abstract
Sorafenib, an oral inhibitor of B-raf, VEGFR2, and PDGFR2-beta, acts against pancreatic cancer in preclinical models. Due to the radio-sensitization activity of both sorafenib and gemcitabine, we designed a multicenter, phase I trial to evaluate the safety profile and the recommended dose of this combination used with concomitant radiation therapy.

Imaging bile duct tumors: staging.
Abdom Imaging

Hide Abstract
Cholangiocarcinoma (CC) is the most frequent neoplasm of the biliary system. According to its anatomic origin in the biliary tree it is usually classified as intrahepatic, perihilar, or extrahepatic distal CC. Tumors originated in these areas differ in biological behavior and management. The stratification of the patients aligned to therapeutic options and prognosis is a key point in the management of CC. Thus, specific staging systems have been designed for each anatomical location. They are precise for surgical planning, to establish prognosis after surgery, or to compare the benefits of different therapeutic approaches, but they are less accurate to stratify patients into a therapeutic decision algorithm. Imaging tools, mainly multidetector computed tomography and magnetic resonance imaging (MRI), allow full assessment of the diagnosis and extension of the tumor. They are especially useful in establishing the correct diagnosis and determining resectability, which reaches a high negative predictive value, identifying those patients in whom surgery will not be effective. We will discuss the different staging systems for CC, the radiologic characteristics with classical and recently described signs that allow a confident diagnosis of the disease and the criteria for resectability of biliary tract malignancies.

Retroperitoneal fibrosis: role of imaging in diagnosis and follow-up.
Radiographics
PUBLISHED: 03-13-2013
Show Abstract
Hide Abstract
Retroperitoneal fibrosis (RPF) encompasses a range of diseases characterized by proliferation of aberrant fibroinflammatory tissue, which usually surrounds the infrarenal portion of the abdominal aorta, inferior vena cava, and iliac vessels. This process may extend to neighboring structures, frequently entrapping and obstructing the ureters and eventually leading to renal failure. The idiopathic form of RPF accounts for more than two-thirds of cases; the rest are secondary to factors such as drug use, malignancies, or infections. If promptly diagnosed and treated, idiopathic and most other benign forms of RPF have a good prognosis. In contrast, malignant RPF, which accounts for up to 10% of cases, has a poor prognosis. Therefore, the most important diagnostic challenge is differentiation of benign from malignant RPF. Imaging plays a key role in diagnosis of RPF. Cross-sectional imaging studies, particularly multidetector computed tomography (CT) and magnetic resonance (MR) imaging, are considered the imaging modalities of choice. Imaging features may help distinguish between benign and malignant RPF, but in some cases histopathologic examination of the retroperitoneal tissue is needed for definitive diagnosis. CT and MR imaging, along with positron emission tomography with fluorine 18 fluorodeoxyglucose, also play an important role in management and follow-up of idiopathic RPF.

Design and endpoints of clinical and translational trials in advanced colorectal cancer. a proposal from GROUP Español Multidisciplinar en Cancer Digestivo (GEMCAD).
Rev Recent Clin Trials

Hide Abstract
Meta-analytic reviews of Randomized Clinical Trials (RCT) have reached contradictory conclusions regarding the benefit of medical interventions in Advanced Colorectal Cancer (ACRC). Surrogate markers of survival benefit, such as response rate (RR) and progression free-survival (PFS) often show contradictory and highly variable correlations. These contradictions can be due to differences in 1) the studies analysed (sources), 2) the quality of clinical trials (intrinsic bias in the design, biased data analysis, heterogeneous PFS definitions) and 3) the second-line strategies between arms. PFS is a more vulnerable target than overall survival (OS), but the latter can also be affected by different biases and additional medical interventions such as secondary resection of metastases or second-line therapies. Therefore the correlation between PFS and survival must be clearly stated if PFS is to be considered as a primary endpoint. Of the differences between studies, only the quality of clinical trials can be improved by a deeper knowledge of both the area of study (i.e. colorectal cancer) and the methodology needed (i.e., clinical and translational trials). The aim of this manuscript is to offer the basic resources to develop experimental trials in ACRC. To this end, techniques for diagnosis and for response assessment are discussed, prognostic factors and treatment standards are critically exposed, and notes about how to design useful translational studies are provided.

Imatinib plus low-dose doxorubicin in patients with advanced gastrointestinal stromal tumors refractory to high-dose imatinib: a phase I-II study by the Spanish Group for Research on Sarcomas.

Hide Abstract
In KIT-expressing Ewing sarcoma cell lines, the addition of doxorubicin to imatinib increases apoptosis, compared with imatinib or doxorubicin alone. On the basis of these in vitro data, the authors conducted a phase 1-2 trial of doxorubicin with imatinib in patients with gastrointestinal sarcoma tumors refractory to high-dose imatinib therapy.

What is Visualize?

JoVE Visualize is a tool created to match the last 5 years of PubMed publications to methods in JoVE's video library.

How does it work?

We use abstracts found on PubMed and match them to JoVE videos to create a list of 10 to 30 related methods videos.

Video X seems to be unrelated to Abstract Y...

In developing our video relationships, we compare around 5 million PubMed articles to our library of over 4,500 methods videos. In some cases the language used in the PubMed abstracts makes matching that content to a JoVE video difficult. In other cases, there happens not to be any content in our video library that is relevant to the topic of a given abstract. In these cases, our algorithms are trying their best to display videos with relevant content, which can sometimes result in matched videos with only a slight relation.
