Strategy for the diagnosis and treatment of bilateral testicular tumor / 中华泌尿外科杂志

ABSTRACT

Objective To evaluate the clinical features and the strategy for the diagnosis and treat- ment of bilateral testicular tumor.Methods The clinical data (including the signs and symptoms,imaging studies,tumor markers,treatment modalities and histopatbologic diagnoses) of 10 cases of bilateral testicular tumor from January 1980 to December 2004 were reviewed.Their age ranged from 19 to 58 years(mean,34 years).Of the 10 cases,8 with metachronous and 2 with synchronous testicular tumors were identified.The clinical stages at the primary and secondary tumor diagnosis were5 cases of stageⅠ,3 of stageⅡ;and 6 cases of stageⅠ,1 of stageⅡ,and 1 of stageⅢ,respectively,in 8 metachronous tumor patients.Two syn- chronous tumor patients were both identified as stageⅠdisease.Histological examination showed the primary tumor (seminoma) in 4 cases and the secondary contralateral tumor (seminoma) in 3.Results Two syn- chronous tumor patients underwent bilateral radical orchiectomy simultaneously,and 8 underwent orchiectomy successively.Retroperitoneal lymph node dissection was performed in 3 cases.Postoperatively,hypogonadism occurred in 10 patients,and 7 of them received androgen replacement therapy.Follow-up ranged from 9 month to 23 years with a mean of 10.5 years.Two patients died of the disease;2 had metastasis (1 of them was alive with metastasis);2 had recurrences and underwent local resection.Conclusions Metachronous bilateral testicular cancers are more common than synchronous bilateral testicular cancers.Seminoma was the most common histopathologic type.Testis-sparing surgery can be performed in selected cases.
