Objective To determine biomarkers of recurrence and survival in patients with spindle cell variant squamous cell carcinoma (SpSCC) of the head and neck. Study Design Retrospective case control study. Setting Tertiary academic center. Subjects and Methods Thirty-two SpSCC patients (mean age, 68.8) between 1987 and 2009 were identified and reviewed. A tissue microarray (TMA) was constructed from tumor specimens. Tumor biomarkers under study included p16, epidermal growth factor receptor (EGFR), p53, EZH2, cyclin D1, CD104, HGFa, p21, and cMET. An additional TMA was constructed from patients with non-SpSCC oral cavity squamous cell carcinoma for comparative purposes. The main outcomes were overall survival (OS), disease-specific survival (DSS), and recurrence-free survival (RFS). Results In the SpSCC cohort, tumors positive for cMet had worse OS ( P < .001). Patients positive for cMet ( P = .007), cyclin D1 ( P = .019), and p16 ( P = .004) had worse DSS. Recurrence-free survival was also worse in patients with tumors positive for cMet ( P = .037), cyclin D1 ( P = .012), and p16 ( P < .001). Compared with the oral cavity cohort, there was a significantly larger proportion of patients in the SpSCC group with tumors staining positive for cMet and a lower proportion of tumors positive for cyclin D1. Conclusion cMet, cyclin D1, and p16 are predictive tumor biomarkers for risk of recurrence and worse DSS in patients with SpSCC.

Spindle cell carcinoma is a rare aggressive biphasic tumor, composed of neoplastic proliferation of both epithelial (squamous) and spindle cell population. It constitutes about 1% of all oral cavity tumors 2a and is almost rare on the tongue; only few cases have been reported so far. This variant of squamous cell carcinoma, comprises major diagnostic problems due to its varied histomorphology and resemblance to sarcomatous lesion; hence diligent screening and IHC markers are mandatory for its diagnosis.

Oral squamous cell carcinoma (OSCC) is a fatal disease caused by complex interactions between environmental, genomic, and epigenetic alterations. In the current study, we aimed to identify clusters of genes whose promoter methylation status correlated with various tested clinical features. Molecular datasets of genetic and methylation analysis based on whole-genome sequencing of 159 OSCC patients were obtained from the The Cancer Genome Atlas (TCGA) data portal. Genes were clustered based on their methylation status and were tested for their association with demographic, pathological, and clinical features of the patients. Overall, seven clusters of genes were revealed that showed a significant association with the overall survival/recurrence free survival of patients. The top ranked genes within cluster 4, which showed the worst prognosis, primarily acted as paraneoplastic genes, while the genes within cluster 6 primarily acted as anti-tumor genes. A significant difference was found regarding the mean age in the different clusters. No significant correlation was found between the tumor staging and the different clusters. In conclusion, our result provided a proof-of-principle for the existence of phenotypic diversity among the epigenetic clusters of OSCC and demonstrated the utility of the use epigenetics alterations in devolving new prognostic and therapeutics tools for OSCC patients.
