PURPOSE: The benefit of adding docetaxel, cisplatin and 5-fluorouracil (TPF) induction chemotherapy to chemoradiotherapy (CRT) in head and neck squamous cell carcinoma (HNSCC) remains uncertain. We aimed to investigate whether ICT is well tolerated when given with prophylactic treatment against predicted adverse effects and which patients benefit most. METHODS: A single-centre audit identified 132 HNSCC patients with stage IVa/b neck node-positive disease, prescribed TPF followed by CRT...

The prognostic value of mucins expression in patients with head and neck cancer (HNC) remains controversial. To address this, a meta-analysis was performed to systematically evaluate prognostic significance of mucins expression in HNC. Electronic and manual searches were performed and a total of 20 studies including 2046 patients were selected for the final analysis. Increased mucins expression was associated with unfavorable overall survival in HNC patients (HR=1.83, 95% CI: 1.43-2.33, p=0.000). Mucins overexpression was also in correlation with more advanced TNM stage (RR=0...

CDC73 interacts with human PAF1 complex, histone methyltransferase complex and RNA polymerase II for transcription elongation and 3' end processing. Its down-regulated expression was immunohistochemically detected in gastric, colorectal, ovarian and head and neck cancers, and positively correlated with aggressive behaviors and unfavorable prognosis of malignancies. We performed a bioinformatics analysis by using Oncomine, TCGA and KM plotter databases. It was found that CDC73 mRNA was overexpressed in gastric, lung, breast and ovarian cancers, even stratified by histological subtypes (p<0...

Hyalinizing clear cell carcinoma (HCCC) is an extremely rare neoplasm of salivary gland origin with a low-grade indolent nature. It is difficult to distinguish from other malignant salivary gland tumours. Clinical outcomes following surgery are generally reported as good. The aim of this study was to further determine the features of HCCC. This study was approved by Medical ethics review of affiliated hospital of jiangsu university. Fourteen new cases of HCCC are reported. The clinical and histopathological data of these 14 cases were analysed alongside those of 141 cases identified in a systematic review of the literature (up to 2016)...

INTRODUCTION: The incidence and clinical significance of lymph node metastasis (LNM, N1) in soft tissue sarcoma (STS) is unclear. Recent studies have focused on extremity/trunk STS (ETSTS). We sought to define the subgroup of patients with LNM at sarcoma diagnosis across all disease sites and histologies. METHODS: We identified and categorized 89,870 STS patients from the National Cancer Data Base (1998-2012) by nodal stage. Pathologically confirmed LNM (pN1) were identified in 1404 patients; 1750 had clinically suspicious but not pathologically confirmed LNM (cN1)...

OBJECTIVE: Lymph node ratio (LNR) was shown to be a prognostic factor in laryngeal and oral cavity primaries. The purpose of this study was to investigate the impact of the lymph node ratio in oropharyngeal squamous cell carcinoma (OPSCC) with a high incidence of HPV-related disease. Therefore, the role of LNR was evaluated as an additional predictive parameter to the 8th edition of AJCC TNM staging system. METHODS: From December 2009 to August 2015, patients diagnosed with primary oropharyngeal squamous cell carcinoma were prospectively enrolled...

REVIEW
Tilmann Bochtler, Harald Löffler, Alwin Krämer
In cancer of unknown primary (CUP), metastases are clinically and histologically confirmed, but the primary tumor site remains elusive after extensive work-up. CUPs make up for 2-3% of all epithelial malignancies. The two prevailing histologies are adenocarcinomas and undifferentiated carcinomas, whereas squamous cell carcinomas, neuroendocrine carcinomas and rare histologies account for the remaining 10%. The diagnostic work-up in CUP relies strongly on a detailed immunohistological (IHC) analysis in order to characterize the tumor type, nowadays aided by molecular techniques...

Bovine actinobacillosis is typically characterized by pyogranulomatous glossitis (wooden tongue). The involvement of other tissues, generally the skin or lymph nodes, has been regarded as atypical or cutaneous. We describe herein 2 outbreaks of actinobacillosis affecting primarily the lymph nodes of the head and neck. The disease affected 40 of 540 lactating cows in a dairy herd and 5 of 335 two-y-old steers in a beef herd. Multiple or single, occasionally ulcerated nodules were observed in the region of the mandible, neck, and shoulder, including the parotid, submandibular, retropharyngeal, and prescapular lymph nodes...

Streptococcus equi subsp. equi is the etiologic agent of strangles, an infectious disease affecting the upper respiratory tract and head and neck lymph nodes of equines. Routine antimicrobial therapy includes penicillin (PEN) as antibiotic of first choice. Streptococci are usually susceptible to PEN and only a few antimicrobial studies had been performed. The aim of this work was to study the antimicrobial susceptibility profile of S. equi from Buenos Aires, Argentina. Ninety-two isolates were studied by the single disk method to PEN, cefotaxime, erythromycin (ERY), tetracycline, enrofloxacin (ENR), trimethoprim sulfamethoxazole (TMS), ciprofloxacin, clindamycin (CLI), streptomycin (STR) and florfenicol...

The diverse malignant, stromal, and immune cells in tumors affect growth, metastasis, and response to therapy. We profiled transcriptomes of ∼6,000 single cells from 18 head and neck squamous cell carcinoma (HNSCC) patients, including five matched pairs of primary tumors and lymph node metastases. Stromal and immune cells had consistent expression programs across patients. Conversely, malignant cells varied within and between tumors in their expression of signatures related to cell cycle, stress, hypoxia, epithelial differentiation, and partial epithelial-to-mesenchymal transition (p-EMT)...

BACKGROUND: For left-sided pancreatic ductal adenocarcinoma (PDAC), radical antegrade modular pancreatosplenectomy (RAMPS) is a reasonable surgical approach for tumor-free margin resection and systemic lymph node clearance. In pancreaticoduodenectomy for PDAC, the superior mesenteric artery (SMA)-first approach (or the "artery-first approach") has become the standard procedure. With improvements in laparoscopic instruments and techniques, some surgeons attempted to apply laparoscopic RAMPS (L-RAMPS) for carefully selected patients with left-sided PDAC...

BACKGROUND: Retinoblastoma is the most common intraocular malignancy occurring in children. It can metastasize to the regional lymph nodes, central nervous system and distant organs usually the bones and bone marrow and very rarely to the soft tissue. Here, we report a case of unilateral retinoblastoma in a 4-year-old girl accompanied by a large metastasis of the parotid and submandibular glands that developed about 6 months previously and gradually increased in size 5 months after enucleation of the left eye...

In cancer patients, circulating tumour-derived DNA (ctDNA) levels imperfectly reflect disease burden apparent on medical imaging. Further evaluation of ctDNA levels over time is needed to better understand the correlation with tumour growth and therapeutic response. We describe ctDNA kinetics within an orthotopic, immunocompetent preclinical rabbit model of local-regionally advanced head and neck squamous cell carcinoma (HNSCC). Monitoring primary tumour and metastatic lymph node volume by computed tomography (CT), we observed a correlation between ctDNA levels and tumour burden...

This series demonstrates unique data assessing the surgical staging of the cN0 contralateral neck in lateralised oropharyngeal squamous cell carcinoma. Only 5 out of 57 patients were found to have occult nodal metastases. The rate appears higher in HPV negative disease (3/5 patients) than HPV positive patients (2/52 patients) This multi-departmental policy in the management of resectable oropharyngeal squamous cell carcinoma led to the reduction of adjuvant radiotherapy field in 52 patients, and appropriate intensification of adjuvant therapy in 5 patients...
