Eosinophilic solid and cystic renal cell carcinoma mimicking epithelioid Angiomyolipoma: series of 4 primary tumors and 2 metastases.

Eosinophilic solid and cystic renal cell carcinoma (ESC-RCC) is a novel entity of rare tumors with rather unique morphology and immunohistochemical profile. Until recently these tumors were characterized by indolent behavior. Herein we describe a series of six primary and metastatic ESC-RCCs morphologically and immunophenotypically mimicking epithelioid angiomyolipoma (eAML). Retrospective review of unclassified RCCs with oncocytic phenotype yielded several candidate cases, 4 of which fulfilled diagnostic c...

Multi-center clinical evaluation of streptozocin-based chemotherapy for advanced pancreatic neuroendocrine tumors in Japan: focus on weekly regimens and monotherapy.

Streptozocin (STZ) is a key agent for treating advanced pancreatic neuroendocrine tumors (pNET). Most STZ regimens for pNET are daily and also include 5-fluorouracil (5FU), whereas STZ monotherapy and weekly regimens have also been applied in daily practice in Japan. The present study aimed to evaluate responses to weekly regimens and to STZ monotherapy, and to identify a predictive marker of a response to STZ.

Constitutive Interferon Pathway Activation in Tumors as an Efficacy Determinant Following Oncolytic Virotherapy.

Attenuated measles virus (MV) strains are promising agents currently being tested against solid tumors or hematologic malignancies in ongoing phase I and II clinical trials; factors determining oncolytic virotherapy success remain poorly understood, however.

Semi-solid and solid frustrated Lewis pair catalysts.

Recently discovered homogeneous frustrated Lewis pairs (FLPs) have attracted much attention for metal-free catalysis due to their promising potential for the activation of small molecules (e.g., H2, CO, CO2, NOx and many others). Hence, a wide range of these homogeneous FLPs have been extensively explored for many advanced organic syntheses, radical chemistry and polymerizations. In particular, these FLPs are efficiently utilized for the hydrogenation of various unsaturated substrates (e.g., olefins, alkyne...

Palliative Surgery for Metastatic Fungating Phyllodes Tumors: A Series of Two Cases.

Local treatment of metastatic cystosarcoma phyllodes is classically viewed with skepticism because it does not provide survival benefit. When these advanced tumors ulcerate, they reduce quality of life dramatically because of associated pain, infection, malodor, massive discharge, and bleeding.

Prognostic significance of CIP2A expression in solid tumors: A meta-analysis.

CIP2A, cancerous inhibitor of protein phosphatase 2A, was initially recognized as an oncoprotein. Recently several studies revealed that CIP2A could function as a prognosis biomarker, however, the result remained not comprehensive, partly due to small number of patients included individually. Here we carried out a meta-analysis of published studies to assess the prognostic significance of CIP2A in solid tumors. All eligible studies were identified through searching PubMed, Embase and Web of Science database...

A phase 1 study of eribulin mesylate (E7389), a novel microtubule-targeting chemotherapeutic agent, in children with refractory or recurrent solid tumors: A Children's Oncology Group Phase 1 Consortium study (ADVL1314).

Eribulin mesylate is a novel anticancer agent that inhibits microtubule growth, without effects on shortening, and promotes nonproductive tubulin aggregate formation. We performed a phase 1 trial to determine the dose-limiting toxicities (DLTs), maximum tolerated or recommended phase 2 dose (MTD/RP2D), and pharmacokinetics (PK) of eribulin in children with refractory or recurrent solid (excluding central nervous system) tumors.

Validation of a plasma-based comprehensive cancer genotyping assay utilizing orthogonal tissue- and plasma-based methodologies.

Liquid biopsies are powerful tools that enable non-invasive genotyping of advanced solid tumors; however, comprehensive, structured validation studies employing validated orthogonal comparator methods are lacking.

Tackling the challenges of brain metastases in solid tumors.

Immune checkpoint inhibitors in non-small cell lung cancer - towards daily practice.

Immunotherapy with immune checkpoint inhibitors (ICIs) revolutionized therapy of solid tumors, among them- lung cancer. PD-1, PD-L1 blockers have been shown to improve overall survival in advanced, metastatic non-small cell lung cancer. In individual patients, 3-5-year survival has been achieved. Nivolumab, pembrolizumab, atezolizumab are approved in lung cancer treatment. Practical observations in reallife show that the results are comparable with those achieved in clinical trials. The effects of ICIs depe...

Can we use robotic surgery for the treatment of pelvic recurrence and locally advanced tumors in gynecological surgery?

Over the past 20 years, feasibility of laparoscopic approaches has been validated in gynecologic surgery. This procedure has specific challenges due its longer learning curve and the limits imposed by the technique. For the surgical treatment of recurrent pelvic cancers or locally advanced tumors, open surgery remains the gold standard for most surgical teams. Robotic assistance could be an interesting alternative. The aim of this study is to present our department's robotic surgical procedures in this spec...

Measurement of multiple solid portions in part-solid nodules for T categorization: Evaluation of prognostic implication.

Our study aimed to analyze the prognostic implication of the multiplicity of solid portion in part-solid nodules (PSNs) on CT and to compare the prognostic performance of various solid portion measures, including the single largest solid portion, solid proportion, and summated multiple solid portion measurements.

Systemic therapies in patients with advanced well-differentiated pancreatic neuroendocrine tumors (PanNETs): When cytoreduction is the aim. A critical review with meta-analysis.

Cytoreduction is sometimes an important aim of systemic anti-tumor therapies in well-differentiated pancreatic neuroendocrine tumors (PanNETs). As there is not a gold standard treatment for these tumors in this field, we conducted a literature review in order to identify objective criteria for treatment choice.

Materials Characterization by Dynamic Nuclear Polarization Enhanced Solid-State NMR Spectroscopy.

High-resolution solid-state NMR spectroscopy is a powerful tool for the study of organic and inorganic materials because it can directly probe the symmetry and structure at nuclear sites, the connectivity/bonding of atoms and precisely measure inter-atomic distances. However, NMR spectroscopy is hampered by intrinsically poor sensitivity, consequently, the application of NMR spectroscopy to many solid materials is often infeasible. High-field dynamic nuclear polarization (DNP) has emerged as a technique to ...

An update on the management of pancreatic neuroendocrine tumors.

Pancreatic neuroendocrine tumors (PNETs) are a rare and heterogeneous group of neoplasia and differ in their clinical presentation, behavior, and prognosis based on both histological features and cancer stage at the time of diagnosis. Although small-sized tumors can be surgically resected, locally advanced and metastatic tumors confer a poor prognosis. In addition, only limited treatment options are available to the latter group of patients with PNETs, such as hormonal analogs, cytotoxic agents, and targete...

Intrahepatic cholangiocarcinoma followed by vascular invasion: is surgical treatment justified?

Intrahepatic cholangiocarcinoma (ICC) is one of the most aggressive tumors associated with poor prognosis. Radical surgery is still the main method of treatment in resectable cases. Certain difficulties are observed in case of locally advanced tumors followed by inferior vena cava (IVC) and portal vein (PV) invasion.

IKZF1 Enhances Immune Infiltrate Recruitment in Solid Tumors and Susceptibility to Immunotherapy.

Immunotherapies are some of the most promising emergent treatments for several cancers, yet there remains a majority of patients who do not benefit from them due to immune-resistant tumors. One avenue for enhancing treatment for these patients is by converting these tumors to an immunoreactive state, thereby restoring treatment efficacy. By leveraging regulatory networks we previously characterized in autoimmunity, here we show that overexpression of the master regulator IKZF1 leads to enhanced immune infil...

Scalp tumors.

Tumors of the scalp are characterized by an impressively broad and heterogeneous clinical spectrum. They frequently exhibit site-specific features distinguishing them from their counterparts elsewhere on the skin. Although mostly benign, diagnosis and treatment of these lesions may pose a significant challenge due to impaired visibility (and thus delayed detection), anatomical circumstances, exposure to (exogenous) noxious agents, distinct histological features, as well as the often-advanced age of affected...

Cytopathology of Solid Variant of Papillary Thyroid Carcinoma: Differential Diagnoses with other Thyroid Tumors.

Solid variant of papillary thyroid carcinoma (SVPTC) is rare, differing from classical PTC (cPTC) in architecture and outcome. We evaluated the cytomorphology of SVPTC cases to assess the feasibility of a preoperative diagnosis.

Solid Halide Electrolytes with High Lithium-Ion Conductivity for Application in 4 V Class Bulk-Type All-Solid-State Batteries.

New lithium halide solid-electrolyte materials, Li YCl and Li YBr , are found to exhibit high lithium-ion conductivity, high deformability, and high chemical and electrochemical stability, which are required properties for all-solid-state battery (ASSB) applications, particularly for large-scale deployment. The lithium-ion conductivities of cold-pressed powders surpass 1 mS cm at room temperature without additional intergrain or grain boundary resistances. Bulk-type ASSB cells employing these new halide sol...

Targeted Therapy in Advanced Thyroid Cancer to Resensitize Tumors to Radioactive Iodine.

Differentiated thyroid cancer (DTC) usually carries an excellent prognosis, but many DTCs dedifferentiate and become RAI-refractory (RAIR) with worse outcomes. Prior studies suggest that targeted therapy (ttx) can downregulate MAPK signaling and sensitize tumors to RAI.

Clinical outcomes of perioptic tumors treated with hypofractionated stereotactic radiotherapy using CyberKnife® stereotactic radiosurgery.

Stereotactic radiation technique is widely reported as an effective treatment for various types of benign intracranial tumors. However, single fraction radiosurgery (SRS) is not recommended for tumors located close to the optic apparatus due to the restricted radiation tolerance dose of the optic pathway. Recent advances in radiotherapy include advanced frameless radiosurgery using hypofractionated stereotactic radiotherapy (HSRT), and this has become an attractive treatment option for perioptic tumors with...

Risk interrelationship among multiple primary tumors: A case report and review of literature.

Along with advanced management in oncology, great progress has been recently achieved in the studies of multiple primary tumors. Several reports have studied the coexistence between lymphoma and either renal cell carcinoma (RCC) or Warthin tumor. However, the level of coexistence between these cases remains unclear due to the absence of a distinct link between them.
