    Notes: Summary The clinical validity of using the cancer antigen (CA) 125 — a surface antigen on malignant epithelial ovarian tumors — for diagnosis and follow-up of ovarian cancer was investigated in a cooperative study. Using a monoclonal antibody (OC 125) to detect CA 125, the sera of 850 patients were analyzed by immunoradiometric assay (IRMA-Kit Centocor). For 199 patients with ovarian cancer, a preoperative sensitivity of 83% and 74% resulted for the usual cut-off points (≥35 and ≥65 U/ml respectively). The positivity rates and quantiles correlated with the stage of disease (FIGO) and with the tumor debulking achieved at primary surgery. The most frequent histological types (serous cystadenoma and the undifferentiated carcinoma of the ovary) showed the highest positivity rates (80% and 90%, respectively, for cut-off at ≥65 U/ml). Elevated CA 125 values were found in 74% of the cases with a relapse and in 79% of the patients with advanced disease (cut-off, ≥65 U/ml) in the follow-up of ovarian cancer. We recommend cut-off at ≥65 U/ml, because the values for only 1% of the female healthy controls (n=251) were above this level. Also 17% of the patients with adnexitis and 8% with benign neoplasias of the ovary showed elevated titers. Therefore CA 125 should not be used for mass screening of ovarian carcinoma. However, it is a helpful laboratory tool in the diagnosis of recurrence and the surveillance of patients with ovarian cancer.

    Description / Table of Contents: Zusammenfassung Es wird über diagnostische Erfahrungen an 10 Patienten mit primärem Hyperaldosteronismus berichtet, bei denen Serumelektrolyte, Plasma-Reninaktivität und Aldosteronsekretion während einer natriumarmen Periode und unter Natriumbelastung untersucht wurden. 7 der 10 Patienten mit klinisch gesichertem Hyperaldosteronismus wurden nach der Diagnosestellung operiert, wobei sich in 3 Fällen ein singuläres Nebennierenrindenadenom fand, in 3 Fällen eine beiderseitige mikronoduläre Hyperplasie und in einem Fall eine Kombination von beiden. Die Natriumbelastung über 7 Tage mit 200–250 mval Natrium pro Tag führte bei 7 von 10 Patienten zur Senkung der Aldosteronsekretion, jedoch in keinem Fall zu einer Normalisierung derselben. Die Plasma-Reninaktivität der Patienten war während der Natriumentzugsperiode in gleichem Maße supprimiert wie während der Natriumbelastungsphase. Bei 8 von 10 Patienten wurde unter NaClreicher Ernährung ein Abfall des Serumkaliums beobachtet im Unterschied zu 76 Patienten mit essentieller Hypertonie, bei denen Natriumbelastung nicht zu Veränderungen des Serumkaliumspiegels führte.
    Notes: Summary In 10 patients with primary hyperaldosteronism, plasma electrolytes, plasma renin activity and aldosterone secretion were assessed during low and high sodium diet. 7 of 10 patients with the clinical syndrome of primary hyperaldosteronism underwent surgical exploration and treatment: in three cases, a singular adenoma was found in the adrenal cortex, three patients showed micronodular hyperplasia of the zona glomerulosa on both sides, and a combination of both was seen in one case. In 7 of 10 patients high sodium diet with 200–250 mval Na+/day for 7 days resulted in markedly lowered aldosterone secretion, but never was normal aldosterone secretion reached. The plasma renin activity of the group of patients with primary hyperaldosteronism was suppressed to a similar extent during low and during high sodium diet. High sodium diet induced a decrease in plasma potassium concentration in 8 of 10 patients which is in contrast with the findings in 76 patients with essential hypertension; in these patients the plasma potassium levels were not modified by changing the daily sodium intake.

    Notes: Summary The potential for immunohistochemical detection of progesterone receptors (PRs) in routinely formalin-fixed and paraffin-embedded cancer tissues by use of the monoclonal antibody Mi 60-10 (mPR1, Dianova GmbH, Hamburg) was evaluated. The PR content of breast cancer tissue was investigated in 170 cases. A positive reaction to Mi 60-10 was found exclusively in the nuclei of benign or malignant epithelial cells. The distribution of PRs was heterogeneous. Immunohistochemical reaction was scored by multiplying the percentage of positive tumour cells by their prevalent degree of staining (Immunoreactive Score or IRS). The IRS values of formalin-fixed tissues (n=170) were compared with those in snap frozen tissues (n=82), with the PR content assayed by a DCC (dextran-coated charcoal) method (n=170), with histopathological grading according to Bloom and Richardson and with the menopausal status of the patient. There was an acceptable ranked correlation (r=0.74) between IRS in formalin-fixed and paraffin-embedded parts and snap frozen parts of the same carcinoma. A good correlation (r=0.72) was also found, when the semiquantitative results of immunohistochemical PR detection in formalin-fixed and paraffin-embedded tissues were compared to PR concentrations measured by a DCC method in tumor cytosols. There was an 80% concordance between the two methods for qualitative discrimination of PR-negative and PR-positive carcinomas. IRS correlated significantly with the degree of histological differentiation of the tumors (P〈0.001) but not with the menopausal status of the women (P〉0.05). Storage of paraffin-embedded tissues did not impair PR detection, for up to at least 5 years. Fixation of tissues in formalin only decreased the immunohistochemical detection rate if fixative acted for more than 24 h.

    Notes: Summary The serum levels of FSH, LH and estradiol-17β (E2) were determined in 110 women aged between 38–48 years who had been hysterectomized 2–10 years previously and were compared with a control group (n=112). In hysterectomized women both FSH and LH levels were higher than in controls during the whole 12 year period. These differences were significant up to 43 years of age. The hypergonadotropism in hysterectomized women correlates with the higher incidence of climacteric symptoms reported in the literature.

    Notes: Summary PP10, a new placental glycoprotein, was studied by a specific and sensitive double-antibody radioimmunoassay in maternal serum and other body fluids throughout pregnancy. The mean value of serum PP10 in healthy nonpregnant individuals was approximately 10 μU/l. During normal pregnancy it rose to 3,500 μU/l. The rate of rise was obtained from 78 normal pregnancies with 279 single assay values from weeks 6–40. The shape of the curve resembled that for other placental proteins (HPL, SP1). PP10 levels in amniotic fluid were measured in 145 samples from weeks 13–55 of normal pregnancies and at term. The mean concentration was 500 μU/l until week 18 and then rose slowly. Cord blood contained only trace amounts. PP10 was not found in maternal urine. The concentration in maternal serum and amniotic fluid was higher in twin pregnancies than in singleton pregnancies. In 46 cases with low birth weights the PP10 levels in maternal serum were significantly lower than normal. Simultaneous measurements of PP10 and E3, HPL and SP1 were made in 17 individual follow-up's. PP10 was comparable with E3 and appeared to be better than HPL and SP1 in predicting intrauterine fetal growth retardation.
