REVIEW
Genrich Tolstonog, Christian Simon
The task of surgical research is to improve the efficacy of available surgical therapeutic modalities, develop new ones, and balance this well with favorable functional outcome. Therefore, surgical research is composed of a translational and a clinical component. In translational surgical research, animal models are used to better understand the biology of head and neck cancers, but even more importantly, the biology of changes to the disease and the microenvironment created by surgical interventions. Animal models additionally allow for the development of image-guided surgery systems, novel strategies of intraoperative adjuvant treatment, and patient "avatars" to test innovative anticancer drug combinations...

The in vivo assessment of the three-dimensional (3D) kinematics of the hip in patients with femoroacetabular impingement (FAI) under weight-bearing conditions has not been previously reported. We evaluated the pre- and postoperative hip kinematics of a 34-year-old man, with a cam-type FAI while squatting, using image-matching techniques with measurement of the rim-neck distance. Post-osteochondroplasty, the α-angle improved from 51.0° to 35.5° and the head-neck offset ratio from 0.04 to 0.23. Coxalgia during squatting disappeared, and the Harris Hip Score improved from 79 to 92 at 1 year post-surgery...

A 2-year-old girl presented to the emergency department with a 3-day history of a painful stiff neck after getting a kick to her head from her older brother. Her general practitioner had recently started her on oral antibiotics for otitis media. Plain film imaging of her cervical spine on admission revealed anterior subluxation of C2 on C3 suggestive of bifacetal dislocation. Subsequent CT imaging confirmed malalignment of the upper cervical spine. The patient was admitted and worked up with MRI of the cervical spine which unexpectedly revealed a large 4×2 cm retropharyngeal abscess extending from C1 to C4...

BACKGROUND: Glyoxalase 1 is a key enzyme in the detoxification of reactive metabolites such as methylglyoxal and induced Glyoxalase 1 expression has been demonstrated for several human malignancies. However, the regulation and clinical relevance of Glyoxalase 1 in the context of head and neck squamous cell carcinoma has not been addressed so far. METHODS: Argpyrimidine modification as a surrogate for methylglyoxal accumulation and Glyoxalase 1 expression in tumor cells was assessed by immunohistochemical staining of tissue microarrays with specimens from oropharyngeal squamous cell carcinoma patients (n = 154)...

Approximately half of the world's 500,000 new oesophageal squamous-cell carcinoma (ESCC) cases each year occur in China. Here, we show whole-genome sequencing of DNA and RNA in 94 Chinese individuals with ESCC. We identify six mutational signatures (E1-E6), and Signature E4 is unique in ESCC linked to alcohol intake and genetic variants in alcohol-metabolizing enzymes. We discover significantly recurrent mutations in 20 protein-coding genes, 4 long non-coding RNAs and 10 untranslational regions. Functional analyses show six genes that have recurrent copy-number variants in three squamous-cell carcinomas (oesophageal, head and neck and lung) significantly promote cancer cell proliferation, migration and invasion...

Background: Squamous cell carcinomas (SCCs) are common head and neck malignancies demonstrating lymph node LN involvement. Recently chemokine receptor overxpression has been reported in many cancers. Of particular interest, CCR7 appears to be a strong mediator of LN metastases, while CXCR4 may mediate distant metastases. Any relations between their expression in primary HNSCCs and metastatic lymph nodes need to be clarified. Aims: To investigate CCR7 andCXCR4 expression in primary HNSCCs of all tumor sizes, clinical stages and histological grades, as well as involved lymph nodes, then make comparisons, also with control normal oral epithelium...

Precursor B-cell lymphoblastic lymphoma (B-LBL) is a rare entity and primary cutaneous B-LBL is an even more uncommon diagnosis that typically affects children. A 4-year-old boy presented with a persistent rash on his left cheek for almost 2 years and was found to have primary cutaneous B-LBL. We report this case to emphasize that B-LBL should be in the differential diagnosis for an otherwise unimpressive persistent lesion in the head and neck region and review all reported pediatric cases of primary cutaneous B-LBL without extracutaneous involvement...

Patients with head and neck malignancies commonly develop metastatic disease, yet rarely do these carcinomas metastasize to the brain. Stereotactic radiosurgery (SRS) is routinely employed to treat brain metastases (BM). This study was undertaken to examine the efficacy of SRS for BM from primary head and neck carcinomas. From 2000 to 2016, a total of 19 patients with 38 lesions were retrospectively identified. All patients presented with a primary head and neck malignancy and subsequently developed metastatic disease to the brain treated with SRS at our institution...

Malignant peripheral nerve sheath tumours (MPNST) are rare soft tissue sarcomas which largely occur in the extremities and the head and neck region. The tumours are aggressive with a high rate of recurrence. Radical surgical resection remains the treatment of choice with adjuvant radiation therapy and chemotherapy still failing to demonstrate a clear benefit. The gastrointestinal tract is an exceedingly rare site for these tumours. We report an unusual case of a young male with an MPNST of the small bowel who presented with an ileocolic intussusception and sigmoid perforation...

Oral cavity carcinoma is the most common cancer in Indian population. Metastatic nodal disease is the most important prognostic factor for oral cancers. In head and neck cancers with clinically N0 neck, standard selective neck dissection is performed by protecting the spinal accessory nerve to remove level IIA & IIB lymph nodes. The purpose of this study was to analyze the significance of level IIB dissection in patients of oral cavity cancer who underwent primary surgery with functional neck dissection. Two hundred ten patients with clinically N0 neck underwent neck dissection, where level IIB lymph nodes were dissected, labelled and processed separately...

BACKGROUND: Shear wave elastography is a relatively new method of quantitative measurement of tissue elasticity. Assuming that malignant lesions are stiffer than benign ones, elastography may provide supplementary information for their discrimination. However, potential confounding factors impacting tissue stiffness should be investigated first. AIMS: The objective of this study was to measure the stiffness of selected tissues of the head and neck in a normal population and to evaluate its relationship to age, sex, and body mass index...

Cisplatin (CDDP) is a chemotherapeutic agent widely used in several anticancer protocols for instance head and neck, testicle, ovarian, lung and peritoneal carcinomatosis. According to the literature, the use of CDDP is associated with several side effects; among them, we highlighted the mucositis. CDDP, when administered by IP, promoted significant intestinal epithelium alterations in an experimental model. Our research group has proposed that the incorporation of CDDP into long-circulating and pH-sensitive liposomes (SpHL-CDDP) could help to overcome some side effects induced by this drug...
