RESUMO
Objective Previons studies showed that,the gene of P16 is a kind of gene suppressing the cancer.its function once lose,the cell may change to cancer.Methods The expression of P16 has a closely relation with the malignant latent and evolve of the oesophagus cancer.ResulIs This research explored the relation between the P16 expression and the prognosis of oesophagus cancer,the results showed the positive rate of the expression of P16 is more low the rate ofexistence is more low,it in dicates the expression rate of P16 can reflect the prognosis of oesophagus cancer cell.Conclusion The expression of P16 missing or descending is closely rehted with the aggravate and evolve of oesophagus cancer,therefore the expression of P16 had a relation with the prognosis of oesophagus cancer.
