[Clinicopathological study of ovarian embryonal carcinoma (Higuchi-Kato)]

Prognoses of embryonal carcinoma (Higuchi-Kato) of the ovary are extremely poor, and new modalities of the treatment are desired. In the present paper, we describe a clinicopathological study of ovarian embryonal carcinoma (Higuchi-Kato) with special references to the treatment and prognosis. 1) The patients examined were 20 in all, 8 belonging to embryonal carcinoma (Higuchi-Kato) Group A, 6 to the Group B, and 6 to the Group C. 2) The median age of patients was 20 years old. 3) The development of tumor was unilateral in all patients but one unsettled. 4) One patient was pregnant when the tumor was discovered. 5) The prognoses of patients in Group C were better than those of others. 6) Serum AFP is a good tumor marker, correlating well with the clinical courses of the patients. 7) To maintain ovarian function of young patients in stage Ia, unilateral adnexectomy with contralateral wedge resection and postoperative intensive chemotherapy are considered to be a choice of treatment method.
