Lymph node metastasis (LNM) is a significant prognostic factor in patients with head and neck cancer, and the ability to predict it accurately is essential to optimizing treatment. Positron emission tomography (PET) and computed tomography (CT) imaging are routinely used to identify LNM. Although large or highly active lymph nodes (LNs) have a high probability of being positive, identifying small or less reactive LNs is challenging. The accuracy of LNM identification strongly depends on the physician's experience, so an automatic prediction model for LNM based on CT and PET images is warranted to assist LMN identification across care providers and facilities...

BACKGROUND AND PURPOSE: Survival after relapse of head and neck rhabdomyosarcoma (HNRMS) after prior external beam radiotherapy (EBRT) is poor, since options for adequate local treatment are often lacking. In this study we describe our experience with salvage AMORE in patients with relapsed HNRMS after prior EBRT. MATERIALS AND METHODS: Patients with relapsed HNRMS after prior EBRT in which salvage AMORE treatment was considered feasible were analysed; this includes patients with parameningeal, head and neck non-parameningeal and orbital localization...

Introduction: Differentiated thyroid carcinoma (DTC) is the most common pathological type of thyroid carcinoma, which includes papillary and follicular subtypes. DTC is usually indolent, characterized by good prognosis, and long-term survival. Total thyroidectomy is the mainstay of treatment in DTC which is followed by diagnostic whole body 131I (WBI) scan. Like other primary malignancies of the head and neck, DTC follows a consistent pattern of spread in the cervical LNs. The central compartment, level VI and VII, is the first sentinel node followed by spread to the lateral compartments levels II-V, followed by the contralateral side...

INTRODUCTION: Head and neck squamous carcinoma (HNSCC) is one of the most invasive types of cancer with high mortality. A previous study has indicated that low levels of let-7d and miR-205 in HNSCC patients are correlated with poor survival. Let-7d and miR-205 are tumor suppressors and regulators of epithelial-to-mesenchymal transition (EMT). However, it is unclear if let-7d and miR-205 together influence cancer cells. AIM: To determine if let-7d and miR-205 expression levels influence HNSCC patient outcome...

Background: Bone metastasis of cancer can be a result from systemic blood spreading or vertebral venous plexus spreading. Systemic blood pathway induced bone metastasis can happen in any bone in the body since the spreading is considered to be random. However, it remains unknown whether there is any pattern of vertebral venous plexus related bone metastasis. In this study, we explored bone metastasis patterns in patients whose primary tumors had been well identified. Methods: We included 290 consecutive cancer patients with bone metastases but no visceral metastases, out of 2559 patients whose bone metastases were diagnosed by positron emission tomography/computed tomography, between Jan 2015 and Oct 2017 at the Fudan University Shanghai Cancer Center...

MicroRNAs (miRNAs) serve as regulatory factors in both healthy tissue and various cancers. Here, we used an miRNA microarray to screen for miRNAs differentially expressed between HNSCC and adjacent epithelial tissue. Among these, levels of miR-141 were significantly reduced in HNSCC tissues. Expression levels of epidermal growth factor receptor (EGFR) were enhanced in tissues with low miR-141 expression but were reduced by miR-141 overexpression, and there was a significant negative correlation between EGFR and miR-141 levels in HNSCC tissues ( P < 0...

OBJECTIVES: Circulating tumor cells (CTCs) are cells that have shed from tumor tissue into the bloodstream, and the detection and characterization of CTCs in head and neck squamous cell carcinoma (HNSCC) still remain a challenge. MATERIALS AND METHODS: CTCs were isolated from 30 patients with HNSCC with recurrent and/or distant metastasis, via the depletion of CD45-positive cells with magnetic beads and the expression of multiple epithelial markers (CK19, EpCAM, EGFR, and c-Met) was analyzed by RT-qPCR with a low concentration of RNA from the CTC population...

OBJECTIVE: There is considerable variation in the travel required for a patient with head and neck squamous cell carcinoma (HNSCC) to receive a diagnosis. The impact of this travel on the late diagnosis of cancer remains unexamined, even though presenting stage is the strongest predictor of mortality. Our aim is to determine whether travel time affects HNSCC stage at diagnosis independently of other risk factors, and whether this association is affected by socioeconomic status. MATERIALS AND METHODS: Cases were obtained from the CHANCE database, a population-based case-control study in North Carolina (n = 808)...

INTRODUCTION: Vascularized lymph node transfer (VLNT) has become the established treatment for secondary lymphedema. The proposed mechanisms of VLNT include lymphangiogenesis and absorptive action of transplanted lymphatic tissue. Therefore, in theory, the lymph node content of lymph node flap is crucial to clinical response. The supraclavicular lymph node flap (SCLNF) has been described as one of the flap options for VLNT. However, its lymph node content has not been fully studied. The aim of this study is to find out the lymph node content of SCLNF with histological examination...

Medullary thyroid cancer (MTC) represents less than 1% of all thyroid cancers. Complete surgical resection remains the mainstay of treatment for locoregional disease. Unfortunately, patients with recurrence may present with metastasis to challenging anatomic locations. We describe the first case of a recurrent MTC metastatic to the parapharyngeal space (PPS) that was managed using a combined transoral robotic surgery (TORS) and transcervical (TC) approach. We review the presentation, natural history, diagnosis and management of recurrent MTC, and describe a novel combined TORS-TC surgical approach for the treatment of PPS metastasis...

Gastrostomy site metastization is considered an uncommon complication of percutaneous endoscopic gastrostomy (PEG) placement in patients with head and neck tumours, but it is important to consider this possibility when evaluating gastrostomy-related symptoms. The authors present the case of a 40-year-old male with excessive alcohol consumption and active smoking, diagnosed with a stage IV oropharyngeal squamous cell carcinoma. The patient developed a paraneoplastic demyelinating motor polyneuropathy that, associated with tumour mass effect, caused dysphagia with need for nasogastric tube feeding...

Head and neck squamous cell carcinoma (HNSCC) is an aggressive cancer. Early detection and management of HNSCC may prevent progression of the disease. Long non-coding RNAs (lncRNAs) may serve as prognostic biomarkers for various cancer types. The current study downloaded an RNA-Seq dataset containing 43 tumor-normal pairs. An independent t-test identified that the expression level of lncRNA LOC541471 was significantly increased in tumor tissues compared with healthy tissues. Additionally, the current study demonstrated that high lncRNA LOC541471 expression was significantly associated with increasing lymph node metastasis classification and perineural invasion...

Oral cancer is a common cancer of the head and neck. Oral squamous cell carcinoma (OSCC) represents almost 90% of the total cases of head and neck cancer. Ubiquitin-specific protease 22 (USP22) is a deubiquitinating hydrolase, and it is highly expressed in various types of cancer, which also typically have a poor prognosis. Aurora-B and Survivin, which belong to the chromosomal passenger complex, are also highly expressed in a number of types of cancer. In the present study, USP22 expression and its associations with Aurora-B and Survivin, and the clinicopathological features in OSCC were explored...

The prognosis for patients with head and neck cancer (HNC) remains poor, owing to uncontrolled tumor invasion and metastasis. Epithelial-mesenchymal transition (EMT) serves an important role in this invasion and metastasis, and transient receptor potential polycystic 2 (TRPP2) enhances metastasis and invasion by regulating EMT in human laryngeal squamous cell carcinoma. The present study examined whether exosomes/TRPP2 small interfering RNA (siRNA) complexes were able to reduce EMT by suppressing TRPP2 expression in FaDu cells, a cell line of human pharyngeal squamous cell carcinoma...
