Background: Metformin, an oral anti-hyperglycemic drug which inhibits mitochondrial complex I and oxidative phosphorylation has been reported to correlate with improved outcomes in head and neck squamous cell carcinoma (HNSCC) and other cancers. This effect is postulated to occur through disruption of tumor-driven metabolic and immune dysregulation in the tumor microenvironment (TME). We report new findings on the impact of metformin on the tumor and immune elements of the TME from a clinical trial of metformin in HNSCC. Methods: Human papilloma virus-(HPV-) tobacco+ mucosal HNSCC samples (n = 12) were compared to HPV+ oropharyngeal squamous cell carcinoma (OPSCC) samples (n …

Locoregional recurrence accounts for majority of the treatment failures in oral cancer patients. Current study aimed to determine the predictors of recurrence and survival in patients with biopsy proven Squamous Cell Carcinoma (SCC) of the oral cavity. This study included 88 patients of squamous cell carcinoma treated at our institution from 2007 till 2013. Primary intervention was surgery in all patients with radiation and chemotherapy in selected patients. Primary end point was locoregional recurrence, distant metastasis and death. Out of 88 patients, 23 (26.1%) patients developed locoregional recurrence and 6 (6.8%) patients developed distant metastasis. Overall survival rate was 77.3%. …

Phosphaturic mesenchymal tumor (PMT) is a rare neoplasm in which the tumor cells produce fibroblast growth factor 23 (FGF23), leading to oncogenic osteomalacia and thus a distinct clinical presentation. However, the pathologic findings of PMT are often non-specific and variable, especially in tumors occurring in the head and neck. We present a case of a 66-year-old female who presented with osteomalacia-related symptoms and was found to have a nasal cavity mass. Histopathologic examination was suggestive of PMT but certain characteristic features were lacking, requiring confirmation of the diagnosis by chromogenic in situ hybridization (CISH) assay for FGF23 mRNA. The patient's …
