Between 1962 and 1983 a total of 26 patients with malignant trophoblastic disease were diagnosed in northern Finland. The incidence of this disease was 1:21,000 pregnancies. Eight patients had choriocarcinoma and 18 an invasive mole. Clinically, 15 patients belonged to the nonmetastatic and 11 to the metastatic group. Of the latter, 4 patients belonged to the low-and 7 to the high-risk categories. During the first years of the study period, cytotoxic chemotherapy, mostly single-drug therapy, was often complemented with adjunctive surgery and/or irradiation. During recent years, single- or multidrug chemotherapy was supplemented with surgery in only one case with chemotherapy-resistant pulmonary metastases. All 26 patients are alive and disease-free, and after therapy 6 of them have given birth to 1-3 children. Our results suggest that malignant trophoblastic diseases can be successfully treated also in small centers of gynecologic oncology with up-to-date knowledge of the principles of modern cytotoxic chemotherapy.

This report reviews the results of therapy in 93 patients with metastatic gestational trophoblastic tumor treated from 1965-1985. Complete remission was achieved in all 42 patients with low-risk metastatic disease and in 34 of 51 patients (67%) with high-risk metastatic disease. Single-agent chemotherapy induced complete remission in 38 of 42 patients (91%) with low-risk metastatic disease. Survival of high-risk patients has improved markedly over the past two decades; complete remission was attained in 13 of 24 high-risk patients (54%) from 1965-1975, and in 21 of 27 (78%) from 1976-1985. Survival correlated with the number of high-risk factors, the prognostic score, and the type of treatment. From 1965-1975, 54% (13 of 24) of high-risk patients were treated with single-agent chemotherapy alone, while in the last decade only 7% (two of 27) were so treated. Twenty-one patients with traditional high-risk factors had a prognostic score of 7 or less, and all achieved remission, with 67% (14 of 21) treated with primary single-agent chemotherapy. The prognostic scoring system was more effective than traditional high-risk criteria at predicting which patients require intensive combination chemotherapy to attain remission.

The unique curability of gestational trophoblastic tumors may in part be attributable to a host immunologic response. The occurrence of rapidly progressive and fatal choriocarcinoma may be favored by histocompatibility between patients and their partners. However, histocompatibility is not a prerequisite for the development and persistence of gestational choriocarcinoma. The expression of HLA by choriocarcinoma cells in culture is enhanced following incubation with gamma-interferon and this may be of both biologic and clinical significance. Complete molar pregnancy is a complete allograft because all molar chromosomes are of paternal origin. Patients with complete mole are sensitized to paternal HLA antigen which is expressed in molar tissue. Other polymorphic antigen systems including trophoblast-leukocyte common antigens and placental-type alkaline phosphatase are also expressed in molar tissue. We have studied the immunopathology of the molar implantation site to investigate possible humoral and cellular immune responses. The relationships among normal placenta, complete mole and choriocarcinoma are not clearly understood. The pattern of expression of oncofetal antigens in these three gestational tissues may be used to assess trophoblastic differentiation. In studies to date, molar trophoblast has the same pattern of expression of oncofetal antigens as normal placental trophoblast. We will review recent advances in our understanding of the immunobiology of gestational trophoblastic disease and suggest new directions for further research.

Metastatic choriocarcinoma can present in bizarre fashions. Two cases with primary neurological presentations are reviewed. Cerebral metastases in choriocarcinoma generally denote a poor prognosis. However, in solitary metastases in the brain, craniotomy and excision followed by chemotherapy may be curative as illustrated by the following two cases. The first patient was diagnosed to have brain metastases 1 1/2 years after an evacuation of her molar pregnancy while the other patient developed cerebral choriocarcinoma 5 months following a spontaneous first trimester abortion. Both presented with neurological symptoms. Both patients are alive and well now, 9 and 5 years respectively after craniotomy and chemotherapy. A brief review of current considerations in the management of cerebral metastases in gestational trophoblastic disease is presented.

Patients with choriocarcinoma are at risk for hemorrhage. The majority of reported cases have occurred in patients with gestational trophoblastic disease. Although choriocarcinoma in the male is a less common entity, a similar tendency exists. In 3 male patients at Memorial Sloan-Kettering Cancer Center hemorrhage developed as a direct consequence of metastatic choriocarcinoma. The blood loss was massive and resulted in the death of 2 patients. Hemorrhage occurred in two distinct settings: immediately after chemotherapy and in patients with rapidly progressive advanced disease. Early recognition and vigorous support were critical in patient management. Surgical excision of bleeding metastases may be beneficial in selected instances.

Eight patients with choriocarcinoma associated with ectopic pregnancy were treated at the John I. Brewer Trophoblastic Disease Center of Northwestern University Medical School from 1962 through 1981. This represented 4% of the 197 patients with documented choriocarcinoma or 1.7% of all 459 patients with gestational trophoblastic disease treated with chemotherapy at the center during this 20-year period. The presenting signs and symptoms were similar to those classically outlined for ectopic pregnancies: amenorrhea and abdominal pain (88%), irregular vaginal bleeding (75%), positive pregnancy test (100%), and adnexal mass (50%). Six patients (75%) had metastatic disease and four of these six had one or more high-risk factors. Two patients (25%) died of metastatic disease, both of whom had received chemotherapy elsewhere before referral to the center.

A brief discussion of the definition, etiology, epidemiology, classification, and prognosis of the gestational trophoblastic tumor (GTT) is presented. Current therapeutic options are summarized. GTTs arise from fetal tissues and can be divided into three histologic categories, hydatidiform mole, chorioadenoma destruens, and choriocarcinoma. Clinically, it is classified as nonmetastatic, metastatic-low risk, or metastatic-high risk. Diagnosis is based on clinical signs and symptoms, ultrasound and X-ray examinations, and the presence of elevated serum levels of the B-subunit of human chorionic gonadotropin (hCG). Primary therapy for hydatidiform mole is evacuation of the uterine contents. Prophylaxis for metastases with actinomycin D sometimes is performed, but generally is not recommended. For persistent disease that is classified as nonmetastatic or low-risk metastatic, a methotrexate-leucovorin rescue protocol is preferred, with actinomycin D used in patients who show resistance to the regimen. Standard therapy for high-risk metastatic disease involves triple agent therapy with methotrexate, actinomycin D, and chlorambucil, but toxicity is significant. Other alternatives include the modified Bagshawe protocol, a VBC (vinblastine, bleomycin, cisplatin) regimen, cisplatin in combination with vincristine and high-dose methotrexate, and VP16-213 (etoposide) in combination with other agents. Other treatment modalities include radiation and surgery. Use of the most appropriate therapies can maximize the survival of a patient with gestational trophoblastic disease.

Twenty-two patients with gestational trophoblastic neoplasia (GTN) were examined by CT of the abdomen and pelvis to assess the usefulness of CT in the detection and staging of GTN. The most common manifestations of GTN by CT were an enlarged uterus in 16 of 20 patients (80%) with bilateral adnexal cysts in 12 of 22 patients (54%). Contrast enhancement of the uterus was inhomogeneous and the cysts were usually unilocular, ranging in size from 1.0 to 6.0 cm. Metastases were found in 13 of 22 cases (59%). Local extension into the broad ligament was present in 5 of 22 cases (23%). Pelvic or periaortic adenopathy or both was not present. Only one patient had liver metastases. We conclude that CT is a valuable tool in the evaluation of patients with GTN.

Sixty two patients with gestational trophoblastic disease were investigated and treated between January 1977-December 1983. The value of pelvic arteriography was examined. The cases included: 45 moles with a simple outcome. 14 cases of invasive trophoblastic neoplasia after evacuation of the mole. 3 choriocarcinomas after full term pregnancy. Pelvic arteriography was performed in 14 patients. 9 of the 14 patients presented with persistent HCG secretion 6 to 8 weeks after evacuation of the mole. Before chemotherapy was begun, we looked for unfavourable prognostic features such as extra-pelvic metastases, multiple pulmonary metastases, high HCG secretion, delay between the initial event and starting chemotherapy of more than six months. The Ishizuka score was calculated. Six arteriography type I readings suggested choriocarcinoma with an Ishizuka score above five. Double chemotherapy (oncovin-methotrexate) was started successfully (with a one year follow up). Only two patients had unfavourable factors. Two arteriography type III suggested persistent moles, with an Ishizuka score below five. Chemotherapy (only methotrexate) was successful). It was not possible to classify the last arteriography, so the patient was treated successfully with double chemotherapy. Three patients failed to recover with chemotherapy. Arteriography was indicated to determine the site of HCG secretion. Three hysterectomies were performed. Tissue choriocarcinoma was found. Two diagnoses of choriocarcinoma were confirmed by arteriography: In one case an unexplained pleurisy appeared six months after full term. HCG was then positive. In the other case, extrauterine pregnancy was first suspected, but the woman had not had intercourse for six months. Arteriography demonstrated tubal choriocarcinoma. So pelvic arteriography is useful for managing complicated gestational trophoblastic disease.

We studied the clinical records of 64 women with malignant trophoblastic disease. Fifty-five patients (68%) were aged 25-50 years. The current pregnancy was preceded by abortion in 24 cases, by molar pregnancy in 23 cases and by normal pregnancy in 17 cases. The most common presenting symptoms were vaginal bleeding, abdominal mass and abdominal pain. Pulmonary lesions were mostly silent, but hemoptysis occurred in seven patients. Metastases were found in 39 patients. Treatment was mainly chemotherapy. Remission for over 12 months occurred in 40 patients, and 21 patients died.
