Clinical analysis of 352 cases of primary retroperitoneal tumor / 解放军医学杂志

ABSTRACT

Objective To analyze the clinical characteristics of primary retroperitoneal tumors(PRPT) and to improve the diagnosis and treatment of these tumors.Methods The clinical characteristics, surgical treatment and prognosis in 352 cases of primary retroperitoneal tumors were retrospectively studied, and the factors affecting postoperative recurrence were also investigated. Results The most common clinical manifestations in 352 cases of PRPT included abdominal mass,abdominal pain,abdominal distention, and lumbar pain. The size of the majority of PRPTs was large, and pathological patterns of them were varied. Urinary system, digestive system and large vessels were often involved. The resection rate was 87.99%. Removal of the involving organs or vessels were often necessary to achieve a complete resection of the tumor. The nature of the tumor and completeness of tumor were the major risk factors for postoperative recurrence. Conclusion The clinical manifestations, pathological types, involved organs and surgical treatment are complicated in PRPTs. Complete resection is the only effective method for the treatment of PRPTs, and it is one of the major factors in reducing recurrence.
