Purpose:
Valosin-containing protein (VCP/p97) is a key regulator of proteostasis and cellular stress response and has been linked to tumor progression and poor prognosis in various malignant diseases. However, data on its role in laryngeal squamous cell carcinoma (LSCC) are lacking.
Methods:
In this retrospective single-center study, VCP/p97 protein expression was analyzed by immunohistochemistry in a cohort of 100 LSCC patients. Expression levels were semi-quantitatively assessed with H-Score, compared to normal tissue if possible and correlated with clinicopathological parameters. Survival analyses were evaluated by Cox regression.
Results:
VCP/p97 was expressed in all tumors. Most LSCC (77.0%) showed a uniform staining pattern. 46 of these tumors (59.7%) exhibited a staining intensity of 2-3. Among the tumors with a non-homogeneous staining pattern (n = 23), two tumors showed a predominance to lower staining (staining intensity 1). In 13 samples a comparison to normal epithelium was possible. In these samples, 9 (69.2%) samples showed higher VCP/p97 expression compared to the normal epithelium and 4 (30.8%) showed lower expression. VCP/p97 H-Score was not significantly associated with tumor stage, grade, lymph node status or patient survival.
Conclusion:
Although VCP/p97 expression is not prognostic in LSCC, its consistent expression may suggest a potential role as a molecular target. Further functional and translational studies are warranted to explore the therapeutic utility of VCP/p97 inhibition in LSCC.
