[A case of recurrent yolk sac tumor of testis in a 3-year-old child successfully treated by VAC (vincristine, actinomycin-D, cyclophosphamide) therapy].

A case of recurrent yolk sac tumor in a three-year-and five-month old child is reported. Left high orchiectomy was performed two years earlier at which time no evidence of metastatic disease was demonstrated. Twenty-four months postoperatively, serum alpha-fetoprotein (alpha-FP) was elevated and recurrent mass appeared in the left para aortic region. Treatment by VAC regimen consisting of vincristine, actinomycin D and cyclophosphamide was performed. Complete response was obtained after two courses of this therapy, which was confirmed by retroperitoneal lymphadenectomy. We believe that this chemotherapy is effective and safe for the treatment of yolk sac tumor of infantile testis.
