Outcome Measures
Primary Outcomes (1)
Event-free survival
Time from study entry until disease progression, death without progression of disease, occurrence of a second malignant neoplasm or last follow-up, assessed up to 3 years
Secondary Outcomes (2)

Baseline
Incidence of p16 loss or deletion using the model of Sather and Sposto
Baseline
Study Arms (1)
Correlative studies
Previously archived tumor samples are analyzed for p53 mutations and p16 deletion by immunohistochemistry, FISH, PCR, and DNA sequencing.
