title: [Embryonal carcinoma (Higuchi, Kato) of the ovary, clinical analysis and recent improvement of treatment using alpha FP as a tumor marker].
abstract: Forty-one cases of embryonal carcinoma were analyzed from a clinico-pathological point of view. The clinical stages of the patients were: 21 cases in stage I, 8 in stage II, 11 in stage III and 1 in stage IV. Survival curves were compared in accordance with clinical stages. A statistically significant difference was demonstrated between stages I and III, and a significant difference was demonstrated between stages I and II. Embryonal carcinoma in a narrow sense and yolk sac carcinoma were compared in survival curve but there were no significant differences between the two. Cases were divided into two that were pure embryonal carcinoma and embryonal carcinoma with other constituent mixtures. A comparison of these two showed that the mixed type had a better survival curve than the pure type. Effects of treatment in two different periods were compared patients who were treated in 1971-1979 belong to the 1st period group and those treated in 1979-1985 to the 2nd period group. A comparison of these two showed a much better survival curve in the 2nd period group. This difference can be attributed partly to a VAC combination chemotherapy and its maintenance for two years and partly to improvements in the operating technique such as added omentectomy and or the introduction of a second look operation. By measuring alpha FP over the whole clinical course, alpha FP was shown to be a good tumor marker reflecting the patient's condition and aggravation of the patient's condition frequently occurred around or somewhat after 15 weeks after primary surgery.
