Purpose : The purpose of this study was to analyze the relationship between apoptotic
index and clinicopathological findings in laryngeal squamous cell carcinomas.
Materials and Methods : Foully-one cases of laryngeal squamous cell carcinomas were
analyzed for the detection of apoptotic bodies by in situ hybridization.
Results : The average apoptotic index was 9.38¡¾2.89. The apoptotic indices were 11.26
¡¾1.86, 8.17¡¾2.55, and 4.32¡¾2.41 in well differentiated, moderately differentiated and
poorly differentiated carcinoma, respectively. The histopathological differences and
apoptotic index were statistically significant(p<0.05). But there was no relationship
between apoptotic index and T stage, nodal status, recurrence and treatment results.
Conclusion : The apoptotic index was only related to cellular differentiation. Also these
results suggest that the numbers of apoptotic bodies in the tumor tissues can make it
possible to presume indirectly the malignant potentiality of the tumor and will help us
to understand the biologic behavior of head and neck cancer.
