Abstract:
OBJECTIVE:To summarize the clinical characteristics and treatments of patients with malignant transformation of sinonasal inverted papilloma (SNIP), and to explore the factors influencing the prognosis of malignant SNIP.
METHOD:To retrospectively analyze the clinical data of 35 patients with malignant SNIP. The prognosis affected by age, gender, pathogenetic locations, pathology, clinical stages and treatments were analysed using Kaplan Meier, Log rank and Cox method.
RESULT:In our research, 5 years survival rate was 68.6% in malignant SNIP. There were 3 factors effecting the 5 years survival rate of malignant SNIP: clinical staging, histopathological features and treatments while gender, age, disease location, and percentage of the malignant cell in the entire tumor tissue had no effect on overall survival rate. Clinical staging and treatment were the independent factors that influenced the prognosis of malignant SNIP (P value was 0.019 and 0.006).
CONCLUSION:Risk factors that independently influence the survival of patients with malignant SNIP were the clinical staging and treatment. The degree of histo pathological features can be the secondary indicator to judge the prognosis of malignant SNIP. Endoscopic surgery or comprehensive therapy performed on patients properly is therapeutically effective.
