Maspin expression in oral squamous cell carcinoma

Area of Science:

• Oncology
• Molecular Biology
• Pathology

Background:

• Maspin (mammary serine protease inhibitor) is a serpin superfamily member with reported tumor suppressor functions.
• Maspin influences key processes in tumor growth and metastasis, including cell invasion, angiogenesis, and apoptosis.
• Maspin expression shows varied prognostic correlations across different cancer types, including head and neck, pancreatic, ovarian, and lung cancers.

Purpose of the Study:

• To investigate the prognostic significance of maspin expression in oral squamous cell carcinoma (OSCC).
• To evaluate the association between maspin expression and clinicopathological features of OSCC.

Main Methods:

• Immunohistochemical analysis of maspin expression was performed on 89 oral squamous cell carcinoma patient samples.
• Statistical analysis, including chi-squared tests, was used to correlate maspin expression with tumor differentiation, lymph node status, and tumor stage.

Main Results:

• Maspin expression was significantly associated with tumor differentiation grade (P = 0.0318) and lymph node status (P < 0.005) in OSCC.
• No significant association was found between maspin expression and tumor stage (P = 0.666).
• Maspin-negative cases showed significantly higher frequencies of lymph node metastasis compared to cases with >5% positive cells (P = 0.0024).

Conclusions:

• Maspin expression is a valuable prognostic marker in oral squamous cell carcinoma, predicting a better outcome.
• Maspin likely plays a crucial role in the progression of oral squamous cell carcinoma, particularly in relation to lymph node metastasis.
