Abstract
Purpose
To identify potential molecular markers for induction chemotherapy of Laryngeal squamous cell carcinoma (LSCC).
Methods
Differently expressed genes between chemo-sensitive group (seven cases) and chemo-insensitive (five cases) group after induction chemotherapy by TPF were identified by microarrays. Bayes network and Random forest analyses were employed to identify core genes for induction chemotherapy. The diagnostic value of these core genes was also evaluated by ROC analysis.
Results
Six genes (SPP1, FOLR3, KYNU, LOC653219, ADH7 and XAGE1A) are highly expressed, while seven gene (CADM1, NDUFA4L2, CCND2, RARRES3, ERAP2, LYD6 and CNTNAP2) present significantly low expression. Among these genes, genes CADM1, FOLR3, KYNU, and CNTNAP2 are core candidates for LSCC chemo-sensitivity. And that the low expression of CADM1 may result in chemo-sensitivity, which leads to high expression of gene FOLR3 and KYNU, and low expression of gene CNTNAP2. Besides, ROC analysis shows that these four genes exhibit effective diagnostic value for induction chemo-sensitivity.
Conclusions
CADM1 may be a potential molecular marker for LSCC induction chemotherapy, while CADM1, FOLR3, KYNU, and CNTNAP2 may provide essential guidance for LSCC diagnosis and follow-up treatment strategies.
