Diagnose nose and treatment of testicular endodermal sinus tumor

Abstract

Objective To investigate the diagnosis and treatment outcomes of testieulax endodermal sinus tumor. Methods Twenty-four cases diagnosed with testieular endodermal sinus tumors from November 1996 to April 2007 were retruspeetively reviewed. Eighteen patients presented with stage Ⅰ disease, 4 presented with stage Ⅰ , and 2 presented with stage Ⅲ. Inguinal radical or-chieetomy were performed in all patients. Retroperitoneal lymph node dissection was performed in 8 ea-ses. Results The histological structures were rather complicated in 24 tumors. Twenty-three eases (96%) were found with reticular pattern, 22(92%) with hyaline body, 20(83%) with glandlike structure, 16(67%) with Shiller-Dural body, and 13(54%) with solid formation. The former 3 kinds were regarded as the main diagnostic criteria. Twenty-one eases were followed up for 20 months to 12 years. During the follow-up, 2 patients died of the disease. Condesions Early diagnosis and combi-nation therapy, including radical orehieetomy and chemotherapy, are the keys to improve the curative effect of testieular endodermal sinus tumors. Active surveillance of AFP is critical for monitoring the recurrence and metastasis of this tumor. Key words: Testicular neoplasms; Endodermal sinus tumor; Diagnosis; Therapy
