PG - 30-2 AB - OBJECTIVE: To assess the relationship of homozygous deletion status of p16 (MTS1/INK4a/CDKN2A), p15(MTS2/INK4b/CDKN2B) genes and laryngeal squamous cell carcinoma(LSCC) progression. METHODS: DNA was extracted from fresh tumors. Homozygous deletion of p16 exon 2(p16E2) in 80 cases of LSCC and p15 exon 2(p15E2) in 67 cases of LSCC were detected by the polymerase chain reaction technique. RESULTS: The p16E2 deletion rate in 80 cases was 12.5%(10/80); the p15E2 deletion rate in 67 cases was 11.94%(8/67); the p16E2 and p15E2 codeletion rate in 67 cases was 5.97%(4/67). CONCLUSION: Homozygous deletion of p16E2 and p15E2 is related with LSCC oncogenesis, and it may play a role to some extent in LSCC malignant progression.
