A 49-year-old male patient was admitted to our hospital complaining of right scrotal mass. Serum tumor markers, HCG, beta-HCG and AFP, were all elevated. After right high inguinal orchiectomy, a pathological report revealed a mixed-type germ cell tumor, which was composed of choriocarcinoma, embryonal carcinoma and seminoma. Because of persistent elevation of these tumor markers, RPLND was performed. There were viable tumor cells in the dissected lymph node specimens. As pulmonary metastases developed after RPLND, the patient was treated with 3 courses of VAB-6 combination chemotherapy (vinblastine, actinomycin-D, cyclophosphamide, bleomycin and cis-platinum). Pulmonary metastases disappeared and tumor markers returned to normal range except for moderate elevation of serum HCG. Two months later, pulmonary metastases developed again with re-elevation of tumor markers. Four courses of EP salvage chemotherapy (etoposide and cisplatinum) were given. After EP chemotherapy, the patient was given etoposide orally for about 7 months. During this period, no abnormality was found except for slight elevation of serum HCG. Five months after discontinuing chemotherapy, serum HCG returned to normal and complete remission was obtained.

Treatment of choriocarcinoma is mostly successful but there is still appreciable mortality from early respiratory failure. A series of 135 patients with choriocarcinoma presenting with dyspnea between 1960 and 1988 was studied to find prognostic factors for early respiratory death and to identify how mortality may be further reduced. Mortality with respect to early respiratory death (ERD) was 11% and was significantly associated with WHO prognostic score, chest X-ray appearance, central cyanosis, tachycardia, anemia, and clinical evidence of pulmonary hypertension. Indicators on chest X ray of high risk of ERD were the presence of more than 10 opacities, extensive opacification of lung fields, size of metastases, and hazy background obscuring the vascular pattern. Intensity of initial treatment was not correlated with this outcome. A set of criteria has been derived which will predict ERD with 100% sensitivity and 38% positive predictive value. These are opacification of lung fields on chest X ray of more than 50%, OR initial plasma hCG level greater than 10(5) when there is anemia and a history of chest pain. Patients presenting with choriocarcinoma and dyspnea who fulfill these criteria should be considered for extracorporeal perfusion techniques. As respiratory failure in this condition is characterized by hypoxemia and right-to-left shunting, extracorporeal perfusion should be effective. Ventilation should be avoided as no patient survived mechanical ventilation.

6 patients with invasive mole and 5 patients with choriocarcinoma were treated from 1983 till 1986. Serum samples were analyzed by simultaneous determining of pregnancy-specific beta-1-glycoprotein (SP-1) using enzyme-linked immunosorbent assay (ELISA) and beta subunit of human chorionic gonadotropin (beta-hCG) using Serono radioimmunoassay kit. In 2 patients with metastatic gestational trophoblastic disease (MGTD) SP-1 peaks were found during chemotherapy. In patients with MGTD with normalized beta-hCG levels a repeated, temporary elevation of isolated SP-1 levels was observed within some months following chemotherapy. After the last isolated peak of SP-1 the pulmonary metastases disappeared. This phenomenon was interpreted as a consequence of the oncolytic process in the affected tissue. In 1 patient with nonmetastatic choriocarcinoma SP-1 ELISA pseudoreaction was found. To recognize these pseudoreactions, a control plate with nonimmunized rabbit IgG was used, simultaneously with SP-1 determinations.

Choriocarcinoma is a rare malignancy in Scandinavia. We present a case of a young primigravida who experienced an uneventful pregnancy and gave birth to a healthy baby. Six days after delivery she underwent neurosurgery for intracranial hemorrhage. Pathological examination of the evacuated hematoma revealed metastatic choriocarcinoma. Further work-up exposed additional metastases in the lungs and liver. The initial serum level of human chorionic gonadotropin (beta-HCG) was 350,000 IU/I. Chemotherapy was given both intravenously and intrathecally. At 10 weeks, beta-HCG had returned to normal. Treatment was continued for another 10 weeks. Two years after cessation of therapy the patient is still in complete remission. In the discussion we review a scoring system to be used in selecting the mode of treatment, and briefly mention diagnosis and prognosis.

Thirty-nine patients with choriocarcinoma and one with post molar trophoblastic tumour are presented. It was often found that there had been a long interval between the preceding pregnancy and the time of diagnosis or presentation. As a result, there was a high incidence of non-gynaecological presenting symptoms and 95 pc of our patients belonged to the high risk or poor prognosis group. The highest rate of cerebral metastases from choriocarcinoma so far reported in the world literature is presented here. At the beginning of 1987, a modified EMA regimen as introduced and has produced a great improvement in survival. The mortality from choriocarcinoma in Harare from 1985 to 1986 was 81 pc. In 1987 to 1988, this has fallen to 31 pc. The follow-up for the patients on the modified EMA regimen varies from four to twenty-four months.

Chemotherapy for brain metastases has been considered ineffective because the drugs do not penetrate the intact blood brain barrier. Alternate explanations for past failures of chemotherapy include observations that 1) many solid tumors which metastasize to brain are drug-resistant regardless of location, 2) brain metastases often occur following failure of primary chemotherapeutic regimens to control systemic metastases, and 3) previous trials of chemotherapy employed agents other than those known to be most effective against the primary malignancy. Furthermore, laboratory studies have demonstrated that cytotoxic levels of many drugs can be measured in tumor tissue from primary and metastatic brain tumors. These clinical and pharmacologic observations suggest that chemotherapy would be expected to have limited value unless known effective combination regimens are employed as first-line therapy in chemosensitive malignancies. Recent reports of chemotherapy for patients with brain metastases from small cell lung carcinoma, gestational choriocarcinoma, germ cell malignancies, and breast carcinoma do describe response rates in the brain similar to those in other organ sites. In conclusion, chemotherapy for cerebral metastases can be expected to be effective only when effective drugs for systemic metastases are available. While the blood-brain barrier may be an additional detriment to successful treatment, other factors may be more important.

This study reports the findings of a ten year review of autopsy records at the University College Hospital, Ibadan, Nigeria of patients who died of malignant tumour metastases to the lungs and pleurae. During the study period 1977 to 1986, a total of 3,549 autopsies were performed out of which 339 cases 10.5 pc died of malignant tumours. One hundred and thirteen of these tumours (33.3 pc) metastasised to the lungs and pleurae among other sites. Further analysis of these 113 patients showed that 49 were male and 64 females giving a male:female ratio of 1:1,3. In addition, the ages of the patients ranged between 9 months and 90 years with a mean of 38.3 years. The uterus was the commonest organ from which pulmonary metastases occurred (28.3 pc), with choriocarcinoma being the predominant historical type of uterine tumour. The liver was the next most common organ 26.5 pc with male to female ration of 3:3,1. Twenty other organs were also identified, the breast, kidney and oesophagus 7 pc each; pancreas ovary and thyroid 3 pc each being the most important. Other organs are adrenals, foot, neck, cervix and rectum--2 pc each.

The propensity of choriocarcinoma to metastasize to lungs, liver and brain is well known. Though theoretically metastases are possible to anywhere in the body, renal metastases are rare. A 56 year old Malay woman who had total abdominal hysterectomy in 1985 for molar pregnancy presented with haemoptysis and dyspnea in 1990. Examination showed she had choriocarcinoma with pulmonary and renal metastases.

All 1391 patients treated for gestational trophoblastic tumors (invasive mole and choriocarcinoma) at the John I. Brewer Trophoblastic Disease Center of Northwestern University between 1969 (when use of combination chemotherapy for initial treatment of high-risk disease came into general use) and 1988 were evaluated. Univariate and multivariate analyses were used to determine the relative importance of prognostic factors with respect to survival. The overall cure rate was 93% (363/391): 100% for 223 patients with nonmetastatic disease and 83% for 168 patients with metastatic disease. The only patients who died had a clinicopathologic diagnosis of metastatic choriocarcinoma. In addition to presence of metastasis (83% vs 100%, p less than 0.0001) and diagnosis of choriocarcinoma (67% vs 100%, p less than 0.0001), number of metastases (47% if greater than 8 vs 92% if less than or equal to 8, p less than 0.0001), metastases to sites other than the lung or vagina (52% vs 91%, p = 0.0002), and previous failed chemotherapy (46% vs 84%, p = 0.0014) demonstrated independent significant effects on survival in patients with metastatic disease. A Brewer score, based on our multivariate analysis of survival in patients with metastatic disease, provided predictability of outcome (likelihood ratio chi 2 statistic, chi 2 = 49.8) comparable to that with the World Health Organization score (chi 2 = 45.3), both of which, in turn, were better predictors than either the traditional Hammond clinical classification system (chi 2 = 34.4) or the International Federation of Gynecology and Obstetrics stage (chi 2 = 22.9).

Tubal gestational trophoblastic disease (GTD) was diagnosed in 16 (0.8%) of 2,100 women with GTD managed at the New England Trophoblastic Disease Center. Tubal partial mole, complete mole and choriocarcinoma were present in 5, 5 and 6 patients, respectively. Patients with tubal GTD were not clinically distinguishable from those with traditional tubal pregnancies. While only one patient with tubal mole developed metastases, four patients with tubal choriocarcinoma presented with metastases. All the patients achieved complete, sustained remission.
