Methods: The expression of P53 an Ki-67 was examined by SP immunohistochemistry in 35 cases of LSCC, with tumor stage were T3–4N0M0. The results were subjected to statistics analysis, combined with the clinical pathologic data and short-term prognosis. Results: In 35 cases LSCC, 2-year recurrence of the P53 positive expression was 60.0
