Methods： The data of 600 cases of PRPT in General Hospital of PLA were reviewed retrospectively. Results： Of 600 cases of PRPT, 546 were surgically treated. Among theme 369 were malignant and 177 benign. 366 cases were followed up for 1 month to 15 years. The 1-years 3-year, and 5-year survival rate in the patients subject to complete resection was 90.5%, 73.2% and 53.6%, respectively, and that in incomplete resection patients was 70.6%, 32.0%, 5.7% respectively （P〈0.01）. The Cox multi-various regression analysis revealed showed completeness of tumor resection, sex and histologic type were associated closely with local recurrence. Conclusion： Sufficient preoperative preparation and complete tumor resection play important roles for reducing recurrence and improving survival.展开更多
