Alpha-fetoprotein was assayed radioimmunologically in 51 samples of sera from 26 patients who had been operated for embryonal cell carcinoma of the testis. The test was found to have good prognostic value. Elevated levels were seen frequently in patients with metastase or who developed metastases. The kinetic study of alpha-fetoprotein allows us to monitor treatment efficiency, as well as to study cancer evolution.

Alpha-fetoprotein (AEP) serum levels were determined by a new radioimmunoassay (sensitivity about 5 ng/ml) in 47 patients with teratocarcinoma of the testis and in 58 cases with seminoma before operation and during the postoperative course of the disease. In 140 healthy adult persons normal AFP levels below 15 ng/ml were measured. Of 14 preoperative cases with teratocarcinoma, 12 (86%) showed pathologic AFP levels over 20 ng/ml up to 3875 ng/ml. Postoperatively, cases free of metastases developed normal AFP concentrations within 4 to 10 weeks, whereas cases with distant metastases retained constant or increasing pathologic levels following a clinical deterioration. Only in three postoperative cases were Ouchterlony-positive results (AFP sensitivity about 10 000 ng/ml) observed. In contrast, patients with seminoma showed normal AFP levels below 20 ng/ml pre- and postoperatively. According to the results, AFP radioimmunoassay is recommended as an important tool for the differentiation of teratocarcinoma from other tumors of the testis and as a useful parameter for the control of therapy and the course of the disease.

Alpha-fetoprotein and human chorionic gonadotropin levels were measured by radioimmunoassays in 260 patients with genitourinary diseases, including 93 patients with testicular tumors. Elevations of alpha-fetoprotein and human chorionic gonadotropin were associated only with non-seminomatous germ cell testicular tumors. Our 32-month experience with serial measurements of the 2 markers in patients with these tumors shows that alpha-fetoprotein and human chorionic gonadotropin must be determined and that together they serve as accurate and sensitive indicators of metastases and are helpful in determining the effectiveness of therapy. However, they have limited value in the differential diagnosis of scrotal masses.

Isoenzyme V of 5'-nucleotide phosphodiesterase (5'-NPD-V) is present in the peripheral sera of patients with hepatic metastases. A total of 122 patients underwent prospective serologic analysis followed by operation for primary tumors of the gastrointestinal tract and careful evaluation of the liver. A positive 5'-NPD-V assay was found in fifty-nine of sixty patients with liver metastases. A negative 5'-NPD-V assay was found in forty-three of sixty-two patients with no evidence of hepatic metastases. The accuracy of the test was 84 per cent, and the predictive value was 75 per cent. Serum 5'-NPD-V was abnormal significantly more frequently in patients with metastatic liver disease than were liver scans or carcinoembryonic antigen (CEA), alpha fetoprotein, serum glutamic oxalacetic transaminase (SGOT), and total serum bilirubin or serum alkaline phosphatase levels.

From June 1981 to June 1989 we diagnosed 174 cases of hepatocellular carcinoma (HCC) at our institution (Piacenza, Northern Italy). Average age was 65.6 years; male to female ratio 3.4. 149 patients were cirrhotic (85.6%); alcohol abuse was present in 88/169 (52.1%); in 53/145 patients all hepatitis B virus markers were negative. Alpha-fetoprotein showed a low diagnostic sensitivity (values above 500 ng only in 49/169 or 29.0%). We used ultrasound (US) examination with a very high identification rate in all cases; pathological diagnosis was achieved by US guided fine-needle aspiration biopsy in 135 patients; in 13, by laparoscopy-histology. Metastases were found in 24/169 cases (14.2%); a second malignancy was diagnosed in 13/169 (7.7%): the most common association was HCC-non-Hodgkin lymphoma. Only 14 patients could be referred to surgery, which significantly improved prognosis.

Malignant mediastinal teratoma containing yolk sac elements are rare tumours and invariably have a poor prognosis. An elevated alpha fetoprotein level is a useful indicator of the malignant nature and the invasiveness of the tumour. A case with such a tumour who also presented with precocious puberty is described. This patient was treated with radiotherapy and chemotherapy prior to radical surgical excision, and has now survived for over 64 months without evidence of metastases.

Although tumor load has proven to be the most relevant prognostic factor in disseminated germ cell tumors (GCT), methods to determine tumor volume for staging have not been studied so far. In a prospective study, we therefore measured the volume of metastases before and during chemotherapy in 27 patients with disseminated GCT. Abdominal tumor volume was calculated using a General Electric CT scan 8800. Total volume was determined by cumulation of 1 cm slices measured by a cursor. Pulmonary volume was calculated by taking each metastasis as a sphere using V = 0.523 x d3, where V = volume and d = diameter. We used linear regression analysis to determine the dependence of tumor markers on volume. Before chemotherapy, the median tumor volume of all patients was 237 (range 4-2690) cm3. The tumor volume was 1-100 cm3 in 30%, 101-500 cm3 in 41%, and over 500 cm3 in 29% of the patients. NED (no evidence of disease) was achieved in 8/8 patients presenting with a small (1-100 cm3) and 9/10 with a moderate (101-500 cm3) tumor volume. In contrast, only 1/8 with advanced tumor load (greater than 500 cm3) achieved NED. While there was a significant correlation between the initial and the residual tumor volume (P = 0.0024, r = 0.72), there was none between the tumor volume and alpha fetoprotein, beta human chorionic gonadotropin, and lactate dehydrogenase. These results suggest that radiological determination of tumor volume is a reproducible and accurate staging method.

Between August 1981 and December 1984, 85 consecutive patients with clinical stage I nonseminomatous germ cell tumors of the testis who were suitable for close observation entered a surveillance study after orchiectomy alone. All patients had unequivocally negative chest x-ray, bipedal lymph-angiography, and computerized tomography of the abdomen and pelvis, and normal levels of alpha-fetoprotein and human chorionic gonadotropin before entering the study. Patients were followed closely for 24 to 64 months (median 42 months) with regular chest x-rays, plain films of the abdomen for lymphangiography control, and serum determinations of alpha-fetoprotein and human chorionic gonadotropin but it was difficult to obtain computerized tomography scans of the abdomen at scheduled intervals for such a long period. Followup was closed December 31, 1986. At that date 62 patients (73 per cent) were continuously free of disease after orchiectomy alone and 23 (27 per cent) suffered relapse. The over-all occurrence rate of retroperitoneal relapses was 16.5 per cent and they usually were detected late, 4 to 36 months (median 10 months) after orchiectomy. Lung metastases were detected much earlier, 2 to 10 months (median 3 months) after orchiectomy. Alpha-fetoprotein and human chorionic gonadotropin elevations preceded the radiographic demonstration of metastases in 8 patients only (35 per cent) and in 1 they were the only sign of relapse. All but 1 patient with relapse were cured with chemotherapy and/or surgery, with an over-all survival rate free of disease of 98.8 per cent. Invasion of the epididymis, rete testis and spermatic cord, primary scrotal surgery, peritumor vascular invasion and embryonal carcinoma were associated with a higher risk for relapse but it was impossible to find clear-cut indications to select patients for adjuvant chemotherapy, retroperitoneal lymphadenectomy or no treatment. Furthermore, the followup of retroperitoneal nodes proved to be much more difficult than expected. Unilateral or modified retroperitoneal lymphadenectomy facilitates management of clinical stage I nonseminomatous germ cell tumors of the testis: only the chest and markers must be followed, the status of the retroperitoneal nodes is known immediately and antegrade ejaculation is preserved in the majority of cases.

Human alpha fetoprotein (AFP) has been detected by the agar double diffusion method in ascitic fluid, cerebrospinal fluid (CSF) and bile, from fetuses, neonates and patients with AFP seropositive hepatocellular carcinoma. AFP was detected in the meconium and faeces of fetuses and neonates respectively. The protein was not detected in the amniotic fluid nor the pericardial fluid. It was found in the urine in only two fetuses that had concomittant renal disease. It was not detected in breast milk of lactating females. When metastases occurred in the lung from a hepatocellular carcinoma producing AFP, the pleural effusions sometimes contained AFP. The concentrations of AFP in the serum and in the other body fluids were about the same. This indicates that other body fluids can be used for the diagnosis of hepatocellular carcinoma.

A case of an unusual type of hepatoblastoma in a 5-month-old male infant is described. The tumor showed the following unusual features as compared with the epithelial and mixed types of hepatoblastoma: (1) The tumor cells presented a primitive anaplastic appearance without any resemblance in terms of cytologic features or arrangement to embryonal or fetal liver. (2) Abundant mucoid material containing acid mucopolysaccharide was present giving a slimy, gelatinous, gross appearance to the tumor and its metastases. (3) Well-defined tubular structures were present in some foci within the tumor parenchyma. (4) The tumor resulted in a rapidly fatal course, with metastases to the lungs and widespread peritoneal seeding despite complete surgical resection of the primary tumor. Yolk sac carcinoma and undifferentiated (embryonal) sarcoma of the liver were considered in the differential diagnosis. On electron microscopic examination, the tumor cells showed cytoplasmic features and junctional complexes consistent with their epithelial origin. Alpha-fetoprotein in the blood, which was markedly elevated prior to surgery, returned to a normal level postoperatively. Hepatoblastoma with the combination of features described above has not been previously reported. Because of the two striking and easily recognizable features viz. total lack of differentiation of tumor cells and presence of abundant mucoid material, the authors designated the tumor as mucoid anaplastic hepatoblastoma.
