AI Article Synopsis
- The study aimed to assess how variations in the L-myc gene could indicate a genetic risk for head and neck nonmelanoma skin cancer (HNNMSC) and lower lip cancer (LLC).
- Researchers conducted a case-control study involving 24 HNNMSC patients, 27 LLC patients, and 51 matched controls, using lab techniques to analyze gene variations.
- Results showed a higher frequency of the LS genotype and S allele in cancer patients, suggesting that L-myc gene polymorphisms could aid in predicting cancer risk and tumor behavior, especially in those with HNNMSC.
Article Abstract
Objective: To evaluate the presence of L-myc gene variations as a genetic predisposition to head and neck nonmelanoma skin cancer (HNNMSC) and lower lip cancer (LLC).
Design: A case-control study.
Setting: An academic institute laboratory.
Participants: Twenty-four patients with HNNMSC and 27 with LLC were compared with 51 age- and sex-matched control subjects.
Main Outcome Measures: Polymerase chain reaction restriction fragment length polymorphism and agarose gel electrophoresis were used to determine the L-myc oncogene genotypes.
Results: The presence of the LS genotype was found to be significantly increased in the study group, whereas the LL genotype was not detected. The S allele was also more frequent in the study group. The SS genotype was found to correlate with aggressive tumor behavior in patients with HNNMSC and a family history of cancer. Patients with LLC displayed significantly less of the SS genotype.
Conclusions: The L-myc gene polymorphism may help detect and prevent HNNMSC and LLC in susceptible individuals. It may also contribute to estimation of tumor behavior in patients with HNNMSC.
