Comment on: Low expression of HSP27 and HSP70 predicts poor prognosis in laryngeal squamous cell carcinoma

Abstract

Borowczak et al. recently explored the prognostic role of heat shock proteins HSP27 and HSP70 in laryngeal squamous cell carcinoma (LSCC). Their study demonstrated that lower expression levels of these proteins were linked to significantly reduced overall survival, suggesting potential utility as prognostic biomarkers in this patient population. This work adds important evidence to the limited pool of molecular predictors available for LSCC. However, paradoxical findings, such as the survival advantage observed with higher HSP expression despite their well-known cytoprotective roles, raise questions regarding underlying mechanisms. Factors such as subcellular localization, treatment intensity, and environmental exposures like alcohol consumption may influence these associations. Consequently, further translational research is needed to validate the prognostic significance of HSP27 and HSP70 and to clarify their clinical applicability in LSCC management.
