#1
Nazanin Maani, Steven W Hetts, Vitaliy L Rayz
Two-scale CFD modeling is used to design and optimize a novel endovascular filtration device for removing toxins from flowing blood. The Chemofilter is temporarily deployed in the venous side of a tumor during the intra-arterial chemotherapy in order to filter excessive chemotherapy drugs such as Doxorubicin from the blood stream. The device chemically binds selective drugs to its surface thus filtering them from blood, after they have had the effect on the tumor and before they reach the heart and other organs...

BACKGROUND: The impact of sarcopenia on the prognosis of patients with hepatocellular carcinoma (HCC) who receive transcatheter intra-arterial therapies, including transcatheter arterial chemoembolization and transcatheter arterial infusion chemotherapy, remains unclear. We investigated the prognostic value of skeletal muscle loss (SML) stratified by cutoffs for sarcopenia and rate of change in skeletal muscle mass over 6 months. METHODS: We retrospectively evaluated 102 patients with HCC treated with transcatheter intra-arterial therapies between 2005 and 2015...

PURPOSE OF REVIEW: The goal of this article is to review the key clinical and radiological features, treatment strategies, and prognosis of lacrimal gland tumors. RECENT FINDINGS: Debulking of the orbital lobe of the lacrimal gland may offer improved control rates in dacryoadenitis without compromise of tear film function. Contrary to previous belief, careful biopsy of the lacrimal gland prior to excision does not appear to increase the risk of recurrence in cases with suspected pleomorphic adenoma...

Background: Cardiac intracavitary metastases from a testicular cancer are very unusual, and intra-cardiac metastasis is exceptionally the first expression of a noncardiac primary neoplasm. We report a case of a young patient for whom a cardiac symptom led to the diagnosis of a metastatic testicular cancer. Case presentation: Our presentation describes an unusual case of a 32 years-old male patient admitted for dyspnea, in whom full examination and tests led to the diagnosis of a huge right ventricular mass revealing a testicular malignant teratoma...

Regional intra-arterial chemotherapy (RIAC) is a potential alternative treatment for advanced pancreatic cancer (APC) with fewer adverse effects than other treatment options. However, specific biomarkers to determine the prognosis of patients with APC have thus far, been unsatisfactory. Glypican-1 (GPC1) in exosomes has been identified as an early diagnostic biomarker for pancreatic adenocarcinoma. The aim of the present study was to investigate whether the presence of GPC1 in extracellular vesicles (EVs) could serve as a predictor of RIAC outcome for patients with APC...

Accumulating clinical evidence indicates that diabetic liver cancer patients are less sensitive to intra-arterial chemotherapy than non-diabetic cancer patients. However, the underlying mechanism remains largely uncharacterized. Here, we report that hyperglycemia inhibits AMPK pathway and subsequently reduces ADR induced DNA damage, resulting in decreased chemotherapeutic sensitivity of Adriamycin (ADR). HepG2 and Bel-7402 cells were treated with ADR in various glucose conditions and then subjected to cell proliferation assay and apoptosis...

REVIEW
William T N Culp
Whenever possible, surgical removal of tumors should be pursued because this likely allows for the best possible outcome for a particular patient; however, this may not be pursued for various reasons. In those situations, interventional radiology (IR) options can be considered as definitive therapy or palliation. Locoregional therapies such as intra-arterial chemotherapy and embolization/chemoembolization, while rarely reported in veterinary medicine, offer an alternative minimally invasive treatment option...

Objective: To investigate the impact of postresection intra-arterial chemotherapy (IAC) on prognosis of stage 2-3 gallbladder cancer (GBC) after curative resection. Methods: Between May 2010 and August 2014, 76 cases of GBC accepted curative surgery in our center and were pathologically staged as 2-3. After resection, 37 underwent 4 courses of intravenous chemotherapy (IVC) following 2 courses of IAC (ART group), and 39 received 6 courses of IVC (SYS group). Both the IAC and IVC regimens consisted of oxaliplatin (85 mg/m2 ) on day 1 and gemcitabine (800 mg/m2 ) on day 1 and day 8...

BACKGROUND: Chemoradiotherapy has a dominant role in therapy for head and neck cancers. However, impressive results are often disturbed by adverse events such as dysphagia, xerostomia, and functional speech and hearing loss. To avoid exceeding toxicity limits in patients with primary and recurrent cancers of the tonsils, chemotherapy was administered intra-arterially via implantable Jet-Port-Allround catheters. METHODS: We report on patients with primary and recurrent cancers of the tonsils...

Radioembolization (RE) is a selective internal radiation therapy (SIRT) delivering targeted, high-dose, intra-arterial radiation directly to the vascular supply of liver tumors. Complications can occur due to aberrant deposition or migration of radiation microspheres into nontarget locations, including normal hepatic parenchyma, lungs, pancreas, and upper gastrointestinal (UGI) tract. We report a case of gastric ulcers due to yttrium-90 (90 Y) seed migration to the stomach to alert clinicians to this rare cause of gastric injury...

REVIEW
Amy C Schefler, Ryan S Kim
Retinoblastoma and uveal melanoma are the most common intraocular malignancies observed in pediatric and adult populations, respectively. For retinoblastoma, intra-arterial chemotherapy has dramatically improved treatment outcomes and eye salvage rates compared with traditional salvage rates of systemic chemotherapy and external beam radiation therapy. Intravitreal injections of chemotherapy have also demonstrated excellent efficacy for vitreous seeds. Uveal melanoma, on the other hand, is treated predominantly with iodine-125 plaque brachytherapy or with proton beam therapy...

Background: Methylenetetrahydrofolate reductase (MTHFR) genetic mutations and intra-procedural inhaled nitrous oxide (N2 O) independently increase blood levels of homocysteine, a compound associated with thrombosis. Patients with MTHFR mutations who also receive N2 O during ophthalmic artery chemotherapy (OAC) for retinoblastoma may have a heightened thrombotic risk. Case presentations: Single-center retrospective review of pediatric patients with advanced retinoblastoma who received OAC and developed choroidal infarcts...

Despite successful introduction of NK-based cellular therapy in the treatment of myeloid leukemia, the potential use of NK alloreactivity in solid malignancies is still elusive. We performed a phase I clinical trial to assess the safety and efficacy of in situ delivery of allogeneic NK cells combined with cetuximab in liver metastasis of gastrointestinal origin. The conditioning chemotherapy was administrated before the allogeneic NK cells injection via hepatic artery. Three escalating doses were tested (3...

BACKGROUND: Continuous monitoring of core temperature is essential during major surgery as a way of improving patient safety. Oesophageal probes or specific arterial catheters are invasive methods used in this setting. A new noninvasive device based on zero-heat-flux (ZHF) technique (SpotOn) seems promising but has been poorly investigated during rapid core temperature changes (RCTC). OBJECTIVE: To assess the accuracy of a SpotOn sensor vs. an oesophageal probe or specific arterial catheter during a slow change in core temperature of less than 1 °C within 30 min and RCTC ≥ 1 °C within 30 min...
