title: [Yolk sac tumor (author's transl)].
abstract: An analysis was made from a histopathological and clinical standpoint of 6 cases of yolk sac tumor over a period of 15 years, treated in the first surgical department of the University of Hokkaido. All these cases, with the exception of one retroperitoneal tumor, were diagnosed as embryonic carcinomas before the study. AFP were examined throughout the duration of treatment and their levels reflected changes corresponding to the effects of treatment and recurrence. They were seen in the form of special fluorescence in the tumor cells using the antibody immunofluorescence method. Radiotherapy and chemotherapy may be effective, but the prognosis of these tumors is poor. Amongst the cases mentioned, only the child with a tumor of testicular origin is in good health.
