RATIONALE: Vaccines made from human papillomavirus may make the body build an immune response to and kill cervical cancer cells. Combining vaccine therapy with surgery may be a more effective treatment for cervical cancer.
PURPOSE: This phase II trial is studying how well giving vaccine therapy together with surgery works in treating patients with early cervical cancer.
Evaluate the systemic immunological response to the human papilloma virus vaccine (TA-HPV) expressing the proteins 16, 18, E6 and E7 examining the cytolytic T cell and the antibody responses in cervical cancer patients.
Investigate further the safety and toxic effects of TA-HPV in these patients.
Assess the proliferative capacity of T cells to the E6 and E7 proteins.
Observe any influence of vaccination with TA-HPV on the disease free interval or patterns of recurrence in these patients.
OUTLINE: This is an open-label, nonrandomized study.
Patients receive 2 vaccinations of the human papilloma virus with proteins 16, 18, E6 and E7 at least 4 weeks apart, with the first vaccination at least 2 weeks before surgery and the second 8 weeks after the first one, unless unacceptable toxicity occurs. Patients who require radiotherapy following surgery receive their second vaccination 4-8 weeks after the first vaccination.
Twenty-eight patients are entered initially; if at least 2 patients show an immunologic response, 16 additional patients are entered.
Patients are followed every 3 months for 2 years, then every 6 months for 3 years, then annually.
PROJECTED ACCRUAL: 44 patients will be entered over 1 year.
