[Diagnosis and treatment of primary retroperitoneal teratoma]
1Department of General Surgery, General Hospital, People's Liberation Army, Beijing 100853, China.
Objective:
To study the diagnosis and treatment of primary retroperitoneal teratoma in adults.
Methods:
The clinical data of 36 adult patients with primary retroperitoneal teratoma were reviewed.
Results:
Nine patients were male and 27 female. Twenty-four patients (66.7%) aged (30.4 +/- 8.0) years were benign, and 12 patients (36.3%) aged (39.6 +/- 10.5) years were malignant. Four (21.1%) cases of presacral tumors and 8 (47.1%) of 17 cases of epigastric tumors were malignant. Clinical features included abdominal or presacral masses and compression symptoms with or without tumor markers. All patients, except one with liver metastasis, underwent radical resection. Patients without malignant metastasis survived, but 5 patients with malignant metastasis survived more than 2 years after operation.
Conclusions:
Malignant metastasis of retroperitoneal teratoma 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.
