Objectives: To evaluate the 5- and 10-year survival prediction of health-related quality of life (HRQoL) scores obtained at diagnosis and at 6, 9 and 12 months after diagnosis in a cohort of curable head and neck squamous cell carcinoma (HNSCC) patients. Materials and methods: HNSCC patients ( n = 109) reported their HRQoL measured by the EORTC Quality of Life Questionnaire (QLQ) general (C30) questionnaire. At diagnosis, the included patients were below 78 years of age and at diagnosis planned treated with curative intent. Clinical variables and self-reported smoking, alcohol consumption and socio-demographic information were registered. From diagnostic blocks, we found 22 patients to be human papillomavirus (HPV) positive. New HRQoL scores were not obtained if the patient treatment changed from curative to palliative throughout the HRQoL data acquisition. Survival was determined from the National Population Register of Norway. Results: Decreased survival with low HRQoL scores from EORTC QLQ scores was demonstrated with HRQoL scores obtained from different time points of the four time points studied. These survival predictions were mostly independent of HPV status, gender, age, TNM stage, tumor site, alcohol consumption, present smoking status and whether comorbidities were present at diagnosis; as well as to some extent with an adjustment of the same HRQoL score/index obtained at diagnosis. The specific indices 'physical function', 'general pain' and 'sleep disturbance' were in particular predictive of survival. Conclusion: HRQoL scores obtained throughout the first year after diagnosis contained prognostic power to overall survival when measured both at 5 and 10 years of observation. [ABSTRACT FROM AUTHOR]

Background: Cancer-associated fibroblasts (CAFs) were shown to be important for tumour progression in head and neck squamous cell carcinomas (HNSCCs). Their heterogeneity and lack of specific markers is increasingly recognized. Integrin α11 was recently shown to be expressed by CAFs and might serve as a specific CAF marker.Aim: To investigate integrin α11 expression and its correlation with the expression of a well-known marker of CAF, alpha smooth muscle actin (α-SMA), in HNSCC.Methods: Fresh frozen (FF) and formalin-fixed paraffin-embedded (FFPE) samples from healthy volunteers (n = 24), oral lichen planus (OLP) (n = 32) and HNSCC (n = 106) were collected together with clinical data after ethical approval. Immunohistochemistry to detect integrin α11 and α-SMA was performed on FF and FFPE samples. qPCR for integrin α11 (ITGA11) and α-SMA (ACTA2) was performed on FF samples. Data were analysed using chi-square test and Kaplan-Meier survival analysis.Results: Significantly higher levels of integrin α11 and α-SMA at both protein and mRNA levels were found in HNSCC vs. normal controls and OLP. A strong correlation was found between integrin α11 and α-SMA expression, and double staining showed their colocalization. Both integrin α11 and α-SMA were detected surrounding metastatic islands. Expression of α-SMA at tumour front but not tumour centre correlated with patient survival.Conclusion: Integrin α11 was overexpressed in HNSCC stroma and colocalized with α-SMA. Expression of α-SMA at tumour front but not tumour centre had prognostic value for survival, pinpointing the importance of assessing tumour front when evaluating stromal molecules as prognostic biomarkers.

Background. Fast and accurate work-up is crucial to ensure the best possible treatment and prognosis for patients with head and neck cancer. The presence or absence of neck lymph node metastases is important for the prognosis and the choice of treatment. Clinical lymph node (N)-staging is done by palpation and diagnostic imaging of the neck. We investigated the current practice of the initial radiological work-up of patients with oral squamous cell carcinomas (OSCC) in the Nordic countries. Methods. A questionnaire regarding the availability and use of guidelines and imaging modalities for radiological N-staging in OSCC was distributed to 21 Head and Neck centres in Denmark (n == 4), Finland (n == 5), Iceland (n == 1), Norway (n == 4) and Sweden (n == 7). We also asked for a description of the radiological criteria for determining the lymph nodes as clinical positive (cN++) or negative (cN0). Results. All 21 Head and Neck centres responded to the questionnaire. Denmark and Finland have national guidelines, while Norway and Sweden have local or regional guidelines. Seventeen of the 19 centres with available guidelines recommended computed tomography (CT) of the cN0 neck. The waiting time may influence the imaging modalities used. Lymph node size was the most commonly used criteria for radiological cN++, but the cut-off measures vary from 0.8 to 2.0 cm. Conclusion. Overall, CT is the most commonly recommended and used imaging modality for OSCC. Despite availability of national guidelines the type and number of radiological examinations vary between centres within a country, but the implementation of a fast-track programme may facilitate fast access to imaging. The absence of uniform criteria for determining the lymph nodes of the neck as cN++ complicates the comparison of the accuracy of the imaging modalities. Well-defined radiological strategies and criteria are needed to optimise the radiological work-up in OSCC. [ABSTRACT FROM AUTHOR]
