Histogram analysis derived from DCE-MRI in head and neck squamous cell cancer – Associations with Microvessel density

ConclusionsHistogram parameters derived from Kep might be used as surrogate imaging biomarkers for microvessel density parameters in HNSCC. MinimumKep showed the highest correlation with vessel area and Mode Kep with vessel count.

ConclusionTregs exert suppressive effects on NKT cell tumoricidal function by inducing more CD4− NKT cell anergy and less CD4+ NKT cell anergy. Both Treg depletion and NKT cell recovery from the anergy state may be important for improving the clinical efficacy of NKT cell-based immunotherapy in patients with advanced cancers.

Conclusions: altogether, our data suggest that resistance to EGFR inhibition combined with radiotherapy in HNSCC may depend on tumor HIF-2 expression and underline the urgent need to develop novel HIF-2 targeted treatments.

In conclusion, a novel yet reliable method for the measurement of intracellular 18F-FDG via GS has been developed, and our results indicate that 18F-FDG uptake is associated with radiation and cetuximab response in HNSCC. PMID: 31620196 [PubMed]

CONCLUSION: The results of the Keynote-048 study have already led to the approval of pembrolizumab in the first line for platin-sensitive HNSCC in the USA and the expected approval in Europe will presumably change the therapeutic landscape in the long term. In the future, effective therapies for patients without a response to programmed cell death 1 (PD-1)/PD-L1 inhibition will be needed. PMID: 31612261 [PubMed - as supplied by publisher]

D, Braz-Silva PH Abstract Despite its effectiveness, radiochemotherapy treatment in the head and neck region is accompanied by acute oral complications such as oral mucositis, dysphagia, xerostomia, and dysgeusia. The aim of this study was to analyze and prospectively assess the frequency and evolution of acute oral complications during radiochemotherapy in patients diagnosed with squamous cell carcinoma in the head and neck region. We have analyzed oral complications of 20 patients during 6 weeks of radiochemotherapy treatment for squamous cell carcinoma. Oral mucositis was evaluated according to the World Healt...

Cancers, Vol. 11, Pages 1583: CD200 Induces Epithelial-to-Mesenchymal Transition in Head and Neck Squamous Cell Carcinoma via β-Catenin-Mediated Nuclear Translocation Cancers doi: 10.3390/cancers11101583 Authors: Seung-Phil Shin A-RA Goh Hyeon-Gu Kang Seok-Jun Kim Jong-Kwang Kim Kyung-Tae Kim John H Lee Yong-Soo Bae Yuh-Seog Jung Sang-Jin Lee The membrane glycoprotein CD200 binds to its receptor CD200R1 and induces tolerance, mainly in cells of the myeloid lineage; however, information regarding its role in solid tumors is limited. Here, we investigated whether CD200 expression, which is enri...

tti Stefania Staibano Oral (OSCC) and oropharyngeal (OPSCC) squamous cell carcinomas show high morbidity and mortality rates. We aimed to investigate the role of the “Chromatin Assembly Factor-1” (CAF-1) p60 and p150 subunits, involved in DNA repair and replication, in OSCC and OPSCC progression and in response to Poly(ADP-ribose) polymerase (PARP)-inhibitors and exposure to ionizing radiation (IR). We immunostained tissue microarrays (TMAs), including 112 OSCC and 42 OPSCC, with anti-CAF-1/p60 and anti-CAF-1/p150 specific antibodies, correlating their expression with prognosis. Moreover, we asses...

AbstractIdentification of effective targeted therapies for recurrent/metastatic head and neck squamous cell carcinoma (HNSCC) remains an unmet medical need. A patient with platinum‐refractory recurrent oral cavity HNSCC underwent comprehensive genomic profiling (CGP) that identified an activating MET mutation (R1004). The patient was treated with the oral MET tyrosine kinase inhibitor crizotinib with rapid response to treatment.Based on this index case, we determined the frequency of MET alterations in 1,637 HNSCC samples, which had been analyzed with hybrid capture‐based CGP performed in the routine course of clinical...

Publication date: Available online 12 October 2019Source: British Journal of Oral and Maxillofacial SurgeryAuthor(s): S.N. Rogers, A. Swain, C. Carroll, D. LoweAbstractAfter their initial presentation of oral squamous cell carcinoma (SCC), patients have a lifelong risk of developing another new SCC of the head and neck. The aim of this study was to establish second primary rates, baseline characteristics (site, clinical or pathological stage, and smoking and alcohol history), timing, presentation, treatment, and outcomes. From the regional unit we analysed records of patients treated with curative intent for their first or...

Conclusion: Our findings suggest that the expression levels of FGD2 and FGD3 mRNAs in HNSC are associated with favorable prognosis and may be regarded as potential prognostic biomarkers. PMID: 31596126 [PubMed - as supplied by publisher]
