Cetuximab, the FDA-approved anti-EGFR antibody for head and neck squamous cell carcinoma (HNSCC), has displayed limited efficacy due to the emergence of intrinsic and acquired resistance. We and others have demonstrated that cetuximab resistance in HNSCC is driven by alternative receptor tyrosine kinases (RTK) including HER3, MET, and AXL. In an effort to overcome cetuximab resistance and circumvent toxicities associated with the administration of multiple RTK inhibitors, we sought to identify a common molecular target that regulates expression of multiple RTK...

AIMS: CD10 is an endopeptidase that degrades variable bioactive peptides in extra-cellular matrix. In addition to the enzymatic degradation, it affects multiple intra-cellular signal transduction pathways. CD10 expression has been extensively studied in human epithelial cancers of numerous organs and sites. However, its presence is not fully determined in thyroid carcinomas, especially in anaplastic thyroid carcinoma (ATC). METHODS AND RESULTS: We examined CD10 by immunohistochemistry (IHC) in 152 thyroid lesions: 9 adenomatous goiters (AGs) and 143 tumors including 47 anaplastic carcinomas...

Lung cancer is the most common cause of cancer-related mortality worldwide, and nonsmall cell lung cancer (NSCLC) accounts for 80% of all pulmonary carcinomas. Recently, long noncoding RNAs (lncRNAs) have been paid attention for exploring treatment of various diseases. Upregulation of DiGeorge syndrome critical region gene 5 (DGCR5) predicts better lung squamous cell carcinoma prognosis; therefore, we explore the role of DGCR5 in lung cancer in our present study. Consecutive patients with LC were treated in our hospital between January 2015 and January 2016...

Oral squamous cell carcinoma is the most common malignant tumor of the head and neck regions and accounts for more than 90% of cancers in the oral cavity. The angiogenesis, lymphangiogenesis and epithelial mesenchymal transition are known to be pivotal for tumor progression and metastasis. In the last decade, much data has been generated concerning the molecular mechanisms of angiogenesis, lymphangiogenesis and its significance in pathological conditions. The main angiogenic and lymphangiogenic factors have been identified as vascular endothelial growth factor A (VEGF-A), vascular endothelial growth factor receptor 2 (VEGFR-2), forkhead box (FOX) C2 while vascular endothelial growth factor C/D (VEGF-C/D), vascular endothelial growth factor receptor 3 (VEGFR-3), Prospero homeobox 1 (PROX1), LYVE-1, podoplanin, Tie/Angioprotein (Ang) 2 and EphrinB2 respectively...

Different cancer stem cell (CSC) populations can be found in many types of cancer, including squamous cell carcinoma (SSC). Diverse reports showed that CSC play a crucial role in the relapse of different types of cancer. CSC sustains tumor growth due to their capacity to self-renew and their potential to initiate secondary tumors with metastatic cancer features. Therefore, the development of methods for the isolation of CSC is a key step to explore the mechanisms underlying CSC maintenance. In this chapter, we provide a method for isolating CSC from cutaneous SSC using immunofluorescence labeling to allow the specific purification of CSC by fluorescence-activated cell sorting (FACS)...

INTRODUCTION: Metastatic non-small cell lung cancer (NSCLC) is a recognized risk factor for VTE. Some systemic treatments may increase this risk further. Here, we present the risk of VTE and its prognostic significance for patients treated with chemotherapy (chemo) and the EGFR monoclonal antibody necitumumab (neci) for metastatic NSCLC. METHODS: Four trials of 1st-line treatment for Stage IV NSCLC were analyzed: two randomized phase 3 studies of cisplatin/gemcitabine ±neci in squamous NSCLC (SQUIRE: N = 1079) and cisplatin/pemetrexed ±neci in non-squamous NSCLC (INSPIRE: N = 616); JFCL (N = 161), a randomized phase 2 trial of carboplatin/paclitaxel ±neci in squamous NSCLC; and JFCK (N = 61), a single arm phase 2 trial of cisplatin/gemcitabine +neci in squamous NSCLC...

Fetal adenocarcinoma is a rare variant of lung adenocarcinoma, which is subcategorized into low-grade and high-grade forms. High-grade fetal adenocarcinoma confers worse prognosis than low-grade fetal adenocarcinoma, but the prognostic differences between high-grade fetal adenocarcinoma and conventional lung adenocarcinoma are unknown. We reviewed tissue sections of 3719 cases of surgically resected primary lung cancers and found 53 lung cancers with a high-grade fetal adenocarcinoma component. We analyzed their clinicopathological and immunohistochemical features, and performed a prognostic analysis of adenocarcinomas with the fetal-type component...

Cell-free microRNAs in plasma provide circulating biomarkers for lung cancer. Most techniques for analysis of miRNAs require a large plasma volume to purify a sufficient RNA yield followed by complicated downstream processing. Small differences in the multiple procedures often cause large analytical variations and poor diagnostic values of the plasma biomarkers. Here we investigate whether directly quantifying plasma miRNAs without RNA purification could diagnose lung cancer. FirePlex assay was directly applied to 20 μl plasma of 56 lung cancer patients and 28 cancer free controls for quantifying 11 lung tumor-associated miRNAs...

Lymphangioma circumscriptum (LC) is a rare, benign condition, predominantly characterized by the malformation of lymphatic skin vessels. Its onset may be congenital or due to secondary causes such as radiotherapy, infections, or surgical procedures. We present the case of a 55-year-old patient with a pathologic history of squamous cell carcinoma of the penis followed by radical penectomy. Due to metastasis to the locoregional lymph nodes, the entire affected area was subsequently treated with radiation therapy, receiving a total dose of 55...

Gastric cancer accounts for a sizeable proportion of global cancer mortality with high morbidity and poor prognosis. Kinesin superfamily proteins (KIFs) are microtubule-dependent motor proteins that function as oncogenes in cancer cells, it has been discovered in recent years. Kinesin family member 2a (KIF2A), a member of KIFs, has received attention for its role in carcinogenesis and its prognostic value in several human cancers such as breast cancer, colorectal cancer, and squamous cell carcinoma. However, the role of KIF2A in human gastric cancer remains unknown...
