Immunotherapy, especially checkpoint inhibitors such as anti-PD1 and anti-PDL1 antibodies, has changed the standard of care and the prognosis of melanoma, but also more recently of lung cancer, renal cancer and Hodgkin lymphoma. Results of preliminary studies in head and neck squamous cell carcinoma (HNSCC) as well as in less frequent tumors of the region, such as nasopharyngeal carcinoma and high grade salivary gland carcinoma, are also promising. Indeed, in a recent phase 3 study, the PD1 inhibitor nivolumab has recently demonstrated a significant improvement in overall survival for platin-resistant recurrent and/or metastatic HNSCC...

The multifunctional SET/I2PP2A protein is known to be overexpressed in head and neck squamous cell carcinoma. However, SET has been reported to have apparently conflicting roles in promoting cancer cell survival under oxidative stress conditions and preventing invasion and metastasis, complicating efforts to understand the contribution of SET to carcinogenesis. In the present study, we overexpressed SET in a spontaneously immortalized oral keratinocyte cell line (NOK-SI SET) and demonstrated that SET up-regulation alone was sufficient to transform cells...

Notwithstanding extended surgical approaches or adjuvant chemoradiotherapy, the development of multiple neoplastic lesions arising in the oral cavity after treatment still represents a critical clinical challenge in the management of patients with oral squamous cell carcinoma. Such clinical behavior of oral squamous cell carcinoma is nowadays better known as "field" cancerization effect as suggested by Slaughter, the author that for the first time tried to describe it in a scientific paper. Field cancerization is now widely accepted not only in head and neck oncology but also in other anatomical districts as well as in different types of epithelial neoplasia...

PURPOSE: To report outcomes for patients with cervical lymph node metastases from an unknown primary site of the head and neck treated with either non-operative therapy or neck dissection followed by adjuvant therapy. MATERIALS AND METHODS: All patients with squamous cell carcinoma of an unknown primary site of the head or neck seen between 2003 and 2013 were reviewed. The Kaplan-Meier method was used to estimate overall survival, local recurrence free survival, loco-regional recurrence free survival, and progression free survival...

BACKGROUND: The aim was to evaluate the geometric and corresponding dosimetric differences between two delineation strategies for head and neck tumors neighboring air cavities. METHODS: Primary gross and clinical tumor volumes (GTV and CTV) of 14 patients with oropharynx or larynx tumors were contoured using a soft tissue window (S). In a second strategy, the same volumes were contoured with an extension to include the parts which became visible on lung window (L)...

There is a long-standing convention to irradiate the great majority of head and neck squamous cell carcinoma (HNSCC) electively to both sides of the neck, to reduce the theoretically increased risk of contralateral regional failure (cRF). With the currently available diagnostic imaging techniques this treatment paradigm means, in our opinion, an overtreatment in considerable proportion of these patients. From all the published studies (n = 11, with 1116 patients treated in total), the incidence of cRF in patients with oropharyngeal cancer treated to one side of the neck is 2...

BACKGROUND: It is unclear why human papillomavirus (HPV)-related head and neck squamous cell carcinoma (HNSCC) has improved clinical behavior compared to HPV-negative HNSCC. We sought to better characterize the immune microenvironment of tongue cancers by examining the CD3 and CD8 TIL pattern in HPV-positive and -negative tumors. METHODS: Histologic sections from 40 oral tongue and oropharyngeal cases were analyzed (n= 21 HPV DNA-positive, n= 19 HPV DNA-negative)...

BACKGROUND: No blood biomarkers to detect early oral cavity squamous cell carcinoma (OSCC) without clinical signs exist - diagnosis is solely based on histology of a visible tumour. Most OSCC patients are diagnosed at advanced stage, which leads to significant morbidity and poor survival. Our aim was to find the serum screening or detection biomarkers in OSCC. METHODS: Serum samples from patients with OSCC treated at the Department of Otorhinolaryngology - Head and Neck Surgery, Helsinki University Hospital (Finland) were collected...

BACKGROUND: Emergency department visits towards the end of life by patients with cancer are increasing over time. This is despite evidence of an association with poor patient and caregiver outcomes and most patients preferring home-based care. AIM: To identify socio-demographic and clinical factors associated with end-of-life emergency department visits and determine the relationship between patients' prior emergency department use and risk of multiple (⩾2) visits in the last month of life...

BACKGROUND: The purpose of this study was to optimize an existing clinical care pathway (CCP) for head and neck cancer with a high-observation protocol (HOP) and to determine the effect on length of intensive care unit (ICU) admission and length of stay in hospital (LOS). METHODS: The HOP mandated initiation of spontaneous breathing trials before the conclusion of the surgery, weaning of sedation, and limiting mechanical ventilation. All patients with head and neck cancer undergoing primary surgery on the HOP were compared to a historical cohort regarding length of ICU admission, ICU readmissions, and LOS...

Recent studies have demonstrated a critical role for nerves in enabling tumor progression. The association of nerves with cancer cells is well established for a variety of malignant tumors, including pancreatic, prostate and the head and neck cancers. This association is often correlated with poor prognosis. A strong partnership between cancer cells and nerve cells leads to both cancer progression and expansion of the nerve network. This relationship is supported by molecular pathways related to nerve growth and repair...

INTRODUCTION: Osteosarcoma is a malignant mesenchymal tumor whose cancerous cells produce osteoid matrix. It is a common primary malignant bone tumor, representing 23% of total head and neck malignancies. Osteosarcomas of the jaws are rare lesions, representing only 4-7% of all osteosarcomas. This presentation discusses the clinical, radiographical, and histopathological features of a case of osteosarcoma of the mandible with unusual histopathological appearance. CASE REPORT: A 21-year-old male patient reported with a diffuse swelling of the right side of mandible with dull ache and increasing difficulties with eating and speech...

PURPOSE: To investigate the relationship between the Diffusion Kurtosis Imaging (DKI) parameters and conventional metrics provided by Diffusion-weighted imaging (DWI) in patients affected by Brain or Head and Neck (HN) cancer. METHODS: Ten patients affected by brain tumor and nine patients with HN tumor underwent a pre-treatment MR examination at 3 T. The largest tumor section was manually contoured by two expert neuroradiologists. The apparent diffusion coefficient (Dapp) and apparent diffusional kurtosis (Kapp) parameters were determined at the voxel level by using the DKI model, and compared to the apparent diffusion coefficient (ADC) and the tissue diffusion coefficient (Dmono) obtained from mono-exponential fitting methods...

BACKGROUND: Pathological fracture of the proximal femur is a main cause of cancer patients losing their ability to walk. Although both osteosynthetic devices (predominantly intramedullary nails) and prosthetic replacement have been widely performed for treatment, controversies exist regarding which procedure should be used for the various conditions. In order to decide the eligibility criteria of a planned randomized prospective study about the treatment of pathological fractures of the proximal femur, we assessed the factors affecting the selection of operative procedures using questionnaires sent to the members of the Bone and Soft Tissue Tumor Study Group (BSTTSG) of the Japan Clinical Oncology Group (JCOG)...

BACKGROUND: During posttreatment surveillance of head and neck cancer patients, imaging is insufficiently accurate for the early detection of relapsing disease. Free circulating tumor DNA (ctDNA) may serve as a novel biomarker for monitoring tumor burden during posttreatment surveillance of these patients. In this exploratory study, we investigated whether low level ctDNA in plasma of head and neck cancer patients can be detected using Droplet Digital PCR (ddPCR). METHODS: TP53 mutations were determined in surgically resected primary tumor samples from six patients with high stage (II-IV), moderate to poorly differentiated head and neck squamous cell carcinoma (HNSCC)...

BACKGROUND AND OBJECTIVES: Optical imaging to guide cancer resections is rapidly transitioning into the operating room. However, the sensitivity of this technique to detect subclinical disease is yet characterized. The purpose of this study was to determine the minimum range of cancer cells that can be detected by antibody-based fluorescence imaging. METHODS: 2LMP (breast), COLO-205 (colon), MiaPaca-2 (pancreas), and SCC-1 (head and neck) cells incubated in vitro with cetuximab-IRDye800CW (dose range 8...

Head and neck cancers are very common worldwide, causing significant morbidity and mortality. Squamous cell carcinoma originating from the epithelial lining of the upper aerodigestive tract is the most common histology. Many patients with head and neck cancers present with advanced stage disease requiring aggressive treatment consisting of extensive surgery and chemo-radiation. Appropriate treatment planning as well as prognosis of tumors depends to a large extent on accurate histological diagnosis and differentiation of malignant from benign lesions...

INTRODUCTION: Patients with head and neck cancer (HNC) submitted to radiotherapy alone or combined chemoradiotherapy present a high prevalence of malnutrition at baseline. Prophylactic use of gastrostomy has been suggested for these patients for delivering enteral nutrition. On the other hand, other authors have failed to demonstrate the effectiveness of this measure over nasogastric tube feeding. MATERIAL AND METHODS: We studied 40 patients with HNC with moderate or severe malnutrition who were offered either prophylactic percutaneous gastrostomy before starting oncologic treatment or close follow-up with nutritional counseling with the placement of a nasogastric tube when necessary...

Sarcomas are infrequent and heterogeneous tumours. They represent 1-2% of all malignant neoplasms in adults and between 4% and 10% of head and neck cancers. METHODS: The research was retrospective, descriptive, and cross-sectional. RESULTS: A study population of 62 patients with a mean age of 44 years was obtained; the most frequent location was the soft tissues of the neck (25.3%) and the mean tumour size was 7.1 cm; the most frequent diagnosis was undifferentiated pleomorphic sarcoma (25...
