Chemoradiotherapy using retrograde superselective intra-arterial infusion for tongue cancer: Analysis of therapeutic results in 118 cases

The tongue is the most common site of oral cavity cancer, the incidence of which has been found to be rapidly increasing. Patients with squamous cell carcinoma (SCC) of the tongue have a significantly worse prognosis than patients with other oral cavity and other head and neck cancers, because of the high rates of local recurrence following definitive treatment [1]. Early stage tongue SCC is treated by glossectomy or definitive radiotherapy including interstitial brachytherapy. For patients with locally advanced oral SCC, including tongue SCC, primary surgery is widely accepted as the standard treatment, and adjuvant concurrent chemoradiotherapy (CRT) is of benefit in patients with nodal disease [2,3].

Conclusion.Compared with SCCHN, SmCCHN carries a worse survival and is more likely to present with more advanced stage.Implications for Practice.Small cell carcinoma of the head and neck (SmCCHN) is a rare subtype of head and neck cancer. In this Surveillance, Epidemiology, and End Results (SEER) data analysis, the characteristics and survival of SmCCHN are compared with those of the common squamous cell carcinoma of the head and neck. Results show that SmCCHN carries a worse prognosis and tends to present at a more advanced stage; SmCCHN also is ten times more likely to originate from the salivary glands. These findings m...

AbstractBackground.DNA copy number variations (CNVs) are a hallmark of cancer, and the current study aimed to demonstrate the profile of the CNVs for oral cavity squamous cell carcinoma (OSCC) and elucidate the clinicopathological associations and molecular mechanisms of a potential marker derived from CNVs, mixed‐lineage leukemia translocated to chromosome 3 protein (MLLT3), in OSCC carcinogenesis.Materials and Methods.CNVs in 37 OSCC tissue specimens were analyzed using a high‐resolution microarray, the OncoScan array. Gene expression was analyzed by real‐time polymerase chain reaction in 127 OSCC and normal tissue...

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...

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 ...
