title: [Evaluation of plasma tumor markers in germinal tumors of the testis].
abstract: Pregnancy specific beta 1 glycoprotein (PS beta 1G), human choriogonadotropin (hCG), alpha-foetoprotein (AFP) and carcinoembryonic antigen (CEA) were measured simultaneously in 58 patients with a progressive germinal testicular tumour, and in 20 patients in complete remission. All markers were negative in all the cases in remission, and in 1 case of progressive teratoma. The specificity of the association of these 4 markers was 76 p. 100, higher than any of them measured alone. There was no correlation between individual markers with respect to histological classification. The highest diagnostic specificity was obtained with hCG in all types of tumours. PS beta 1G was associated with hCG but with a lower specificity. AFP is mainly related to embryonic carcinoma but may be raised in all forms of tumour, except seminomas. CEA was positive less often, irrespective of the type of tumour, and never alone. The value of measuring these tumour markers is double: on the one hand it allows better characterisation of the tumour, and on the other, the clinical course and efficacy of treatment can be followed-up more closely and tumour recurrence may be diagnosed at an early stage.
