Aim: The novel primary end-point of the present study was to ascertain β-arrestin-1 expression in a cohort of consecutive patients with laryngeal squamous cell carcinoma (LSCC) with information available on their cigarette-smoking habits. A secondary end-point was to conduct a preliminary clinical and pathological investigation into the possible role of β-arrestin-1 in the epithelial-to-mesenchymal transition (EMT), identified by testing for E-cadherin, Zeb1, and Zeb2 expression, in the setting of LSCC. Methods: The expression of β-arrestin-1, E-cadherin, zeb1, and zeb2 was ascertained in 20 consecutive LSCCs. Results: Statistical analysis showed no significant associations between β-arrestin-1 and EMT (based on the expression of E-cadherin, Zeb1, and Zeb2). The combined effect of nicotine and β-arrestin-1 was significantly associated with a shorter disease-free survival ( P=0.01) in our series of LSCC. This latter result was also confirmed in an independent, publicly available LSCC cohort ( P=0.047). Conclusions: Further investigations on larger series (ideally in prospective settings) are needed before we can consider closer follow-up protocols and/or more aggressive treatments for patients with LSCC and a combination of nicotine exposure and β-arrestin-1 positivity in tumor cells at the time of their diagnosis. Further studies on how β-arrestin functions in cancer via different signaling pathways might reveal potential targets for the treatment of even advanced laryngeal malignancies.
