CDKN2A (p16) promoter hypermethylation influences the outcome in young lung cancer patients.

Purpose: Non-small cell lung cancer (NSCLC) occurs most frequently in individuals older than 60 years of age. Currently, no biological indicators associated with NSCLC in younger patients (30 to 60 y) have been identified. To explore epigenetic influences, promoter methylation of selected tumor suppressor genes was analyzed in early-stage NSCLC patients ranging in age from 30 to 87 years at diagnosis.

Lymphogranuloma venereum proctosigmoiditis is a mimicker of inflammatory bowel disease.
