Etoposide is a semisynthetic podophyllotoxin derivative with a broad spectrum of antitumor activity and a relatively high therapeutic index. The synergism in animal with cis-platinum, cyclophosphamide, BCNU, and cytosinarabinoside is interesting for combination regimen. Mechanisms of action are inhibition of nucleoside transfer and of DNA and RNA synthesis, single stranded breaks, inhibition of protein synthesis and of microtubular assembly. While in lower concentrations etoposide is acting cell-cycle-dependent with accumulation of cells in the G2-phase it has, in high concentrations, also a cellcycle-phase-unspecific lethal effect. Most suitable is the oral and i.v. application of etoposide in fractionated doses of 80--120 mg/m2 on 3--5 consecutive days and repetition after 21 [14--28] days. Side effects are dose-limiting bone marrow toxicity,
nausea
, vomiting, fever, hypotension, phlebitis, mucositis, neuropathy, cardiotoxicity, alopecia. Etoposide is one of the most active single agents in small-cell bronchus carcinoma with a remission rate of 37% (10% CR), and is very active in NHL (36%), testicular carcinoma (37%), AMML (35%),
choriocarcinoma
(35%), and neuroblastoma (29%). The role of etoposide in combination with other active drugs in these tumors is currently investigated in bronchus and testicular carcinoma and NHL, where etoposide will belong to the drugs of the first choice in the future.

Seventeen patients with germ cell tumours of ovary were treated with 4 cycles of cisplatin, bleomycin and vinblastine (PVB) chemotherapy (CT). All patients had undergone prior surgery: hysterectomy + bilateral salpingo-oophorectomy + omentectomy-5, salpingo-oophorectomy + debulking surgery-10 and biopsy alone in 2 patients. Four of seventeen patients had relapsed earlier and received PVB as second line therapy. FIGO staging revealed: stage IIB in one, III C in 12 and stage IV in 4 patients. Gross residual disease (> 2 cm) was present in 13 patients. The most common cell types were dysgerminoma-5, endodermal sinus tumour-5, immature teratoma-5,
choriocarcinoma
and mixed germ cell tumour in one patient each. Twelve patients (70.5%) achieved significant response; complete response-11, partial response in one patient. The common side effects of CT were
nausea
/vomiting, myelosuppression, fever, mucositis, diarrhoea and alopecia. One patient died due to CT toxicity. Three complete responders underwent second look surgery and were found free of disease. This study confirms that PVB is an effective combination in the treatment of advanced and recurrent germ cell tumours of ovary and can be given over brief period. The toxicity of the regimen is moderate.

Twenty-eight patients with
choriocarcinoma
have received the three kinds of combination chemotherapy since 1983 at our department, i.e., MOA consisting of moderate dose methotrexate (MTX), actinomycin-D (Act-D) and vincristine, MEA (moderate dose MTX, Act-D and etoposide) and FA (high dose 5-Fluorouracil and Act-D). The clinical and laboratory data obtained in the 28 patients were summarized as follows; 1. The MOA regimen was administered to 4 patients primarily and to 2 secondarily. All of the 6 patients attained remission, but finally two (33.3%) developed relapse. 2. The MEA regimen was administered to 12 patients primarily and to 12 secondarily. Of the 24 patients, five (20.8%) were found to be resistant to the MEA regimen. Nineteen patients (79.2%) attained remission, but 2 (10.5%) developed recurrence. 3. The FA regimen was attempted in one patient primarily and in 6 secondarily. Although one patient died, the remaining 6 achieved remission and one relapse has been observed in the 6 cases. 4. By applying the above mentioned 3 combination chemotherapy regimens, the overall survival rate was pushed up from 64% to 90% in
choriocarcinoma
patients. 5. Three patients finally died of the disease but not from the side effects of the combination chemotherapies. The major adverse effects were alopecia,
nausea
, vomiting and myelosuppression. In particular, serious myelosuppression was caused by the MEA or FA regimen in 5-7% of all chemotherapy courses.

Methotrexate, a folic acid antagonist, is approved by the US Food and Drug Administration for use in rheumatoid arthritis, psoriasis, and various types of cancer, including
choriocarcinoma
, and has also been used to terminate ectopic pregnancies. Misoprostol, a prostaglandin, is approved for the prevention of gastric ulcers induced by nonsteroidal anti-inflammatory drugs. In France, the UK, and Sweden, misoprostol and another prostaglandin is used with mifepristone (RU486) to induce abortion in early pregnancy. Recent articles in the press have suggested that in early pregnancy, an intramuscular injection of methotrexate and oral or vaginal administration of misoprostol offers a medical alternative to a surgically induced abortion. This paper describes the mechanisms of action, pharmacokinetics, clinical use, and adverse effects of the two drugs. It is concluded that an intramuscular injection of methotrexate followed up to seven days later by the intravaginal administration of misoprostol can terminate an early intrauterine pregnancy. Headache,
nausea
, vomiting, diarrhea, and prolonged bleeding have occurred. However, in the few studies published to date, no serious complications have been reported.

Multidrug resistance is a major obstacle in successful systemic therapy of gynecologic malignancies. The objectives of this study are to evaluate the activity of cyclosporin A used to overcome drug resistance in a variety of gynecologic malignancies. Forty women (29 with ovarian cancer, 7 with uterine cancer, 3 with cervical cancer, and 1 with
choriocarcinoma
) were treated with cyclosporin A, 4 mg/kg intravenously, 6 hours before and 18 hours after the specific chemotherapeutic agent, to which the tumor had developed drug resistance. All patients had shown resistance to the chemotherapy agent used in combination with cyclosporin A. All patients had been heavily pretreated (mean, 2.8 previous chemotherapy regimens). Overall, among 38 available patients with gynecologic malignancies, a 29% objective response rate was observed. Twenty-six (65%) of all patients received three or more cycles of cyclosporin A. There was a 25% response rate for patients with ovarian cancer patients and 50% for those with uterine cancer. There were no responses among the three patients with cervical cancer, and the patient with
choriocarcinoma
had a complete response. All patients were evaluable for toxicity. Leukopenia and
nausea
were the most common toxic reactions, but in most cases they were transient, and only three patients required a treatment delay. The most common grade 3 or 4 toxicity was thrombocytopenia, which was observed in 22% of the patients. Cyclosporin A is well tolerated and has significant potential for reversal of chemoresistance in heavily pretreated patients with ovarian and uterine malignancies.

The recurrence or metastasis of intracranial pure germinomas as germ cell tumours of different histological types has rarely been reported. The present report concerns the first case in the literature of intracranial recurrence of a germinoma transformed into a
choriocarcinoma
. A 17-year-old man presented with a 1 month history of headache. MRI revealed a homogeneously enhanced mass within the pineal and suprasellar regions. The tumour was resected, and histological examination identified it as a pure germinoma. After resection, the patient underwent chemotherapy and radiotherapy and the mass disappeared. At 5 years and 5 months later, the patient presented with
nausea
and headache, and recurrence of the tumour was revealed in the left lateral ventricle. The tumour was resected and histological diagnosis identified it as a
choriocarcinoma
. The patient was treated with chemotherapy and radiotherapy, but died due to dissemination 1 month later. An autopsy was not performed.

We report a case of a young female patient presenting with a high serum beta-HCG levels, amenorrhea,
nausea
and anemia which mimicked pregnancy followed by upper gastrointestinal bleeding. A gastric tumor was shown on endoscopy. Histopathologic evaluation revealed Primary Gastric
Choriocarcinoma
(PGC). The patient was treated with three cycles of standard nongestational
choriocarcinoma
chemotherapy. Tumor persistence was evidenced by CT Scans and high serum beta-HCG levels. The patient died approximately six months after diagnosis. Our case report suggest that PGC is a highly aggressive tumor that is often associated with liver and lungs metastasis without evidence of pelvic organ abnormality and is associated with some hormonal effects, such as amenorrhea, anemia, nausea and vomiting mimicking pregnancy in young adult female

Primary gastric choriocarcinomas are very rare, and their prognosis is extremely poor. A 37-year-old woman presented with amenorrhea, vaginal spotting and severe
nausea
, which mimicked a pregnancy and gestational trophoblastic disease. The serum level of the beta-subunit of human chorionic gonadotrophin (beta-hCG) was significantly increased. An endoscopic biopsy of the stomach mass showed the features of a
choriocarcinoma
, with marked anaplasia and necrosis. Immunohistochemical staining for beta-hCG showed positive results in the
choriocarcinoma
. Chemotherapy for the
choriocarcinoma
was administered, but she died 8 months following diagnosis.

A 10 year old girl was admitted to our hospital due to headache,
nausea
, and weight loss for about half a year. She also had visual field disorders. Suprasellar tumor was found by X-ray computed tomography, and magnetic resonance imaging showed a ring-like lobulated enhanced mass with hemorrhage and necrosis. Biopsy of this lesion showed primary intracranial
choriocarcinoma
on histopathological examination. The serum human chorionic gonadotropin (hCG) level was measured after the biopsy and was elevated at 71,298.2 IU/L. The patient died due to hydrocephalus caused by an increase in the size of the tumor with a larger amount of hemorrhage than the preoperative features. If young patients present with a suprasellar lobulated mass with hemorrhage, the serum hCG level should be measured before operation.

A 17-year-old male patient presented to the clinic with a headache,
nausea
, and vomiting. Magnetic resonance imaging demonstrated a fat-containing and -enhancing heterogeneous tumor in the third ventricle, and fat droplets within the ventricles and the subarachnoid space. Obstructive hydrocephalus was also present. Emergency subtotal removal of the mass was performed via interhemispheric transcallosal approach. The histopathological diagnosis was a mixed germ cell tumor that was composed of embryonal carcinoma, yolk-sac tumor, germinoma, and immature teratoma containing a large amount of mature elements. The patient was referred for postoperative chemoradiotherapy. A mixed germ cell tumor is a rare type of nongerminomatous germ cell tumor that is made up of at least two different types of germ cell tumors. These may include germinoma,
choriocarcinoma
, embryonal carcinoma, yolk sac tumor, mature teratoma, immature teratoma, or teratoma with malignant degeneration. As far as we know, this is the first reported case of a primary third ventricle mixed germ cell tumor with leptomeningeal dissemination of the immature teratoma component that contains grossly visible mature elements at admission.
