Diffusing Alpha Emitters Radiation Therapy (DART) Brachytherapy for Recurrent and Radio-Resistant Head and Neck and Skin Cancer: A New Treatment Concept

The first clinical trial in humans with skin and oral cavity squamous cell carcinoma (SCC) was performed in order to evaluate the effect of a unique intratumoral alpha radiation-based tumor ablation treatment termed Diffusing Alpha emitters Radiation Therapy (DaRT).

Opinion statementStandard-of-care treatment for the majority of patients with locoregionally advanced squamous cell carcinoma of the head and neck (SCCHN) is either upfront surgery followed by adjuvant treatment as indicated by intraoperative or pathologic findings or concurrent chemoradiation reserving surgical salvage for non-responsive disease. An attempt at upfront complete resection should be pursued if feasible in patients with oral cavity or paranasal sinus primary tumors. Given multimodality treatment paradigms, patients with locoregionally advanced SCCHN should be managed in a multidisciplinary setting. Modern rad...

Lee Fah Yap Ian C. Paterson Head and neck squamous cell carcinoma (HNSCC) is the sixth most common cancer worldwide and includes squamous cell carcinomas of the oropharynx and oral cavity. Patient prognosis has remained poor for decades and molecular targeted therapies are not in routine use. Here we showed that the overall expression of collagen subunit genes was higher in cancer-associated fibroblasts (CAFs) than normal fibroblasts. Focusing on collagen8A1 and collagen11A1, we showed that collagen is produced by both CAFs and tumour cells, indicating that HNSCCs are collagen-rich environments. We then focused on ...

Authors: Fan FS, Yang CF Abstract A 53-year-old male patient was diagnosed with squamous cell carcinoma of buccal mucosa with synchronous diffuse peritoneal carcinomatosis, a very rare presentation for oral cancer. His disease was highly resistant to intensive systemic chemotherapy and progressed rapidly. So far as we know, there were only five cases with peritoneal involvement by metastatic head and neck cancer reported prior to this patient in the English literature. Immunohistochemistry study revealed that tumour specimens from both oral cavity and peritoneum were negative for tumour necrosis factor alpha and CD...

CONCLUSIONS: Together, these results implicate PD-1 expression by T cells in the mechanism of functional immunodominance among independent T cell clones within a progressing tumor, and support the use of neoadjuvant PD-1 immune checkpoint blockade in patients with surgically resectable carcinomas.

This study evaluated predictive factors for the feasibility of oral intake in adjuvant CCRT for patients with LASCCHN.MethodsThis study retrospectively analyzed 117 LASCCHN patients who underwent surgery followed by adjuvant CCRT with cisplatin at Shizuoka Cancer Center between April 2008 and December 2018. To investigate predictive factors for the feasibility of oral intake, tumor factors, treatment factors and social factors were included in multivariate analyses.ResultsOf the 117 patients, 25 received total laryngectomy and 92 received other surgery. In multivariate analysis, total laryngectomy [HR (hazard ratio) 0.09,P...

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...

n Human papillomavirus (HPV) infection is the cause of a growing percentage of head and neck cancers (HNC); primarily, a subset of oral squamous cell carcinoma, oropharyngeal squamous cell carcinoma, and laryngeal squamous cell carcinoma. The majority of HPV-associated head and neck cancers (HPV + HNC) are caused by HPV16; additionally, co-factors such as smoking and immunosuppression contribute to the progression of HPV + HNC by interfering with tumor suppressor miRNA and impairing mediators of the immune system. This review summarizes current studies on HPV + HNC, ranging from potential modes of oral transmission of ...

ConclusionsBaseline HN-LIPI is associated with worse OS for ICI in R/M SCCHN but not with PFS. Control cohort results and multivariate models will be further presented at the congress, which would elucidate the prognostic and/or predictive impact in R/M SCCHN population.Legal entity responsible for the studyNeus Bast é.FundingHas not received any funding.DisclosureV.
