OBJECTIVE: To study the diagnosis and treatment of @entity44 in adults. METHODS: The clinical data of 36 adult @entity1 with @entity44 were reviewed. RESULTS: Nine @entity1 were male and 27 female. Twenty-four @entity1 (66.7%) aged (30.4 +/- 8.0) years were benign, and 12 @entity1 (36.3%) aged (39.6 +/- 10.5) years were malignant. Four (21.1%) cases of @entity5 and 8 (47.1%) of 17 cases of @entity5 were malignant. Clinical features included abdominal or presacral masses and compression symptoms with or without @entity5 markers. All @entity1 , except one with liver @entity3 , underwent radical resection. @entity1 without malignant @entity3 survived, but 5 @entity1 with malignant @entity3 survived more than 2 years after operation. CONCLUSIONS: Malignant @entity3 of retroperitoneal @entity44 is closely related to the age of adults. Early radical resection is the optimal treatment. Adjuvant chemotherapy can induce a short-time remission in those with germ cell elements.
