Operations for pulmonary metastases were carried out on 33 patients from January 1st 1976 to December 31st 1985 at the Surgical Division, University of Cologne. In six cases each, the primary tumors were hypernephromas, colorectal carcinomas and osteocarcinoma. There were five cases of melanoma, three cases of testicular carcinoma, two cases of corpus carcinoma and two cases of soft-tissue sarcoma as well as one case each of parotid, tonsillar and laryngeal carcinoma. The large number of metastases could be determined in 21 cases (64%) by means of preoperative radiodiagnostics with X-rays of the chest in two planes, conventional tomography and computer tomography of the thorax. Computer tomography was the most efficient single investigation. 17 patients received atypical resection and lobectomy was carried out in 16 cases. For all patients, the cumulative survivals revealed a one-year actuarial survival of around 70% and a three-year actuarial survival of about 20%. Patients with several metastases (two to six) had a very much poorer prognosis than patients with solitary pulmonary metastases. There was no connection between the surgical technique selected and the expected survival time in any case. The tumor-free interval between operation on the primary tumor and resection of the pulmonary metastases only had a slight prognostic significance.

Calcium channel blockers of 3 chemical classes and calmodulin antagonists have recently been shown to enhance the cytotoxicity of conventional cancer chemotherapeutic agents. We tested the ability of nifedipine, a dihydropyridine class calcium channel blocker, to enhance the cytotoxicity of cisplatin, the current chemotherapeutic of choice against human head and neck tumors and testicular carcinoma. Both in vitro and in vivo, combination therapy with nifedipine and cisplatin resulted in synergistic inhibition of tumor cell proliferation, primary tumor growth and appearance of spontaneous pulmonary metastases. This combination also significantly increased the survival of mice bearing cisplatin-resistant tumors. This is the first indication that calcium channel blockers can enhance the cytotoxicity of cisplatin as well as the first demonstration that calcium channel blockers can enhance cytotoxicity of chemo-therapeutic agent against a solid tumor and its metastases.

The usefulness of lymphangiography and computerized tomography was evaluated in 167 consecutive patients with pathological stages I and II testicular carcinoma and metastases of less than 5 cm. Lymphangiography demonstrated 74.4 per cent sensitivity, 77.6 per cent specificity and 76.0 per cent over-all accuracy. Computerized tomography revealed comparable results, with 74.3 per cent over-all accuracy, 73.7 per cent sensitivity and 75.0 per cent specificity. The combination of lymphangiography and computerized tomography performed in 35 patients consistently improved the diagnostic possibilities of either technique alone in patients with positive nodes, reducing the false negative rate from 27 to 10 per cent. On the other hand, this combination increased the false positive rate from 25 to 37 per cent in patients with negative nodes. In patients with clinical stage I disease for whom a wait-and-see policy after orchiectomy is adopted at our institute both methods must be considered mandatory. In all other situations computerized tomography alone should be the preferred procedure in the diagnosis of retroperitoneal lymph node metastases from testicular carcinoma.

Metastatic testicular carcinoma is unusual. A case of carcinoma of the prostate with metastases to the testis and epididymis is reported. Routes of metastatic spread of neoplasm to the testis are discussed. Easily removable cancer may remain in the scrotum when using the socalled subcapsular orchiectomy without complete removal of the scrotal contents.

This is the third case, reported in the literature, of transient cortical blindness that occurred during treatment of testicular carcinoma with cisplatinum, vinblastine and bleomycin. The presence of transiently pathological computerized tomography and brain scan suggests that this alarming event may not only be a toxic side effect of chemotherapy, but also a symptom related to eradicable subclinical metastases.

In the first five-year period of the Danish Testicular Carcinoma Study (DATECA) 1058 consecutive testicular germ cell tumours were examined. Of these, 554 were seminomas comprising 515 of typical type, 26 anaplastic and 13 spermatocytic; 497 were non-seminomas comprising 145 pure tumours and 352 mixed tumours of various types. Among the various subtypes of non-seminomas embryonal carcinoma (EC) was recorded in 87 per cent, endodermal sinus tumour (yolk sac tumour; EST) in 22 per cent, teratoma (T) in 55 per cent and choriocarcinoma (CC) in 17 per cent. Only very few tumours were pure EST or pure CC. Five tumours were recorded as 'others or uncertain'. The tumours were graded with regard to various histologic features. Moderate and severe necrosis, bleeding, and a large number of mitoses were significantly more frequent in non-seminomas. The presence of tumour tissue at the resection margin was also more frequent in non-seminomas. Tumours with a largest diameter of less than 2.5 cm had already caused metastases in 16 per cent of the seminomas and 29 per cent of the non-seminomas. Increasing size of the tumours was associated with increasing frequency of metastatic disease but this association was not directly proportional. Distribution of the various histologic types according to the stage of disease varied. Thus, 78 per cent of the seminomas presented in stage I while 54 per cent of the non-seminomas had localized disease. Anaplastic seminomas were distributed similarly to the non-seminomas while all spermatocytic seminomas, with one exception, were recorded as stage I. Of non-seminomatous subtypes pure EC was associated with the highest frequency of stage III, followed by mixed tumours containing CC components. Although the present series is large the heterogeneity of germ cell tumours demands further investigation of larger numbers to confirm some of the findings.

Prognostic factors in carcinoma of the testis were studied in 1058 adult patients treated in Denmark from 1976 to 1980. Separate analyses of the prognostic factors were carried out within the subgroups formed by a classification of the patients according to main histologic type (seminoma, non-seminoma) and the clinicoradiologic stage (I, II and III). The prognosis was measured by relapse-free survival (stage I and II), and survival (stage II and III). The prognostic value of 19 clinical and histologic parameters was evaluated using logrank tests and multiple regression analyses. An elevated HCG level and the size of retroperitoneal metastases were associated with a significantly adverse prognosis for seminoma in stage II. For non-seminomas the following parameters had a significant influence on the prognosis. Stage I: postoperative HCG level, local invasion and number of mitoses. Stage II: size of retroperitoneal metastases, postoperative HCG level, tumour size and local invasion. Stage III: presence of liver or lung metastases, postoperative HCG level, presence of choriocarcinoma or endodermal sinus tumour, and age.

A child with widespread metastases successfully treated with chemotherapy alone is described. One course of combination chemotherapy using cis-platinum, vinblastine, and bleomycin produced disappearance of multiple pulmonary metastatic lesions. Four courses of therapy produced shrinkage and tumor sterilization of an abdominal mass. Twenty-six months after initiation of chemotherapy the patient is well, off of all therapy for fourteen months, and free of disease or drug related complication with normal creatinine clearance and alphafetoprotein determinations. The published adult experience demonstrates that this therapy is extremely effective for the treatment of metastatic embryonal cell carcinoma of the testis in young adults, and our case report extends this favorable experience into childhood. Toxicity is substantial, but justifiable considering the poor outlook associated with widespread metastatic disease. Collectively, the reviewed data suggest that further trials of this type of therapy are indicated in children.

Fifteen patients with disseminated non-seminomatous testicular cancer, 13 of whom had advanced disease, underwent surgery for residual tumor after induction chemotherapy. Complete remissions were achieved in 7 of 9 patients with mediastinal or pulmonary metastases and in 2 of 6 patients with retroperitoneal metastases. Patients with alpha-fetoprotein (AFP) levels over 10(4) ng/ml at diagnosis and/or a positive AFP preoperatively failed to achieve complete remission. Complete remissions were obtained in all 8 patients who had resection of necrosis, mature teratoma, immature teratoma or mature teratoma with malignant foci, but in only 1 of 7 patients who had resection of embryonal carcinoma or yolk sac tumor with other components. Of 9 patients with complete remission, 8 have remained free of disease after a median follow-up time of 29 months (range 6-66 months) and one had a contralateral non-seminomatous testicular cancer removed after 60 months. In addition to being therapeutically successful, the combined use of chemotherapy followed by surgery for residual tumor may lead to a better understanding of the influence of chemotherapy on the biology of testicular carcinoma.

A young man with a swollen left leg was referred to us for a thromboscintigram/lung scan. The unexpected visualization of the liver during the flow study after intravenous injection of Tc-99m MAA into the dorsal veins of both feet provided the clue to his underlying problem. He was shown to have extensive venous collateralization in the left pelvis, and to a lesser degree on the right, due to a large pelvic mass. This was shown to consist of metastases from a previously treated testicular carcinoma. Venous drainage from the legs was shunted into the mesenteric circulation, which them emptied into the portal vein, thereby carrying the radiopharmaceutical to the liver. No uptake was seen in the spleen.
