Twenty-four patients with far advanced malignant tumors, resistent to established chemotherapy,, were treated with the combination of MNU and Cyclophosphamide. The drugs were administered in six-day cycles sequentially. MNU in doses of 4 mg/kg body weight and Cyclophosphamide in doses of 8 mg/kg body weight were given. Results of treatment showed response (greater than 50% tumor regression) in 10 (42%) of the 24 treated patients. Seven remissions were complete and three partial. Patients with Hodgkin's disease, malignant melanoma and breast cancer responded to this combination chemotherapy. Objective remissions were obtained also in five of thirteen patients with primary or metastatic brain tumors and in five of nine patients with pulmonary metastases. Nausea and vomiting were the main toxic effects, especially after injections of MNU. Myelosuppression was noted in about 50% of treated patients. Since this combination of cytostatics showed significant antitumor activity, further investigations are necessary on a larger number of patients and in other types of malignant tumors.

A case of mucinous adenocarcinoma of the stomach is described in a 20-month-old child with a large abdominal mass. The lesion arose from the lesser curvature of the stomach and invaded the submucosa and lymphatic channels. A partial response to chemotherapy, including vincristine, Cytoxan, actinomycin D, and adriamycin, was noted, but the patient died 3 1/2 months following diagnosis shortly after gastric perforation and peritonitis developed. Autopsy revealed a pattern of widespread visceral metastases, accompanied by pathologic findings suggestive of ataxia-telangiectasia. A diagnosis of mucinous adenocarcinoma, although it is rare, should be considered in the evaluation of primary neoplasms of the stomach in children.

Diethylnitrosamine (DEN) was applied orally to a total of 250 female Wistar rats in a single dose (d) of 3 mg/kg body weight 5 times a week for a duration of 20 weeks. After approximately 150 days exploratory laparotomy was performed to all animals. By inspection of the liver they were divided into 4 stages of disease according to the extent of cancer formation. The reaction of rats with DEN induced liver tumors was tested using a 4-drug combination chemotherapy with different equitoxic doses of Adriamycin (Adm), Methotrexate (Mtx), 5-Fluorouracil (5-FU) and Cyclophosphamide (CP). No benefit of drug treatment could be noted. In drug treated animals no decrease in the development of the liver tumors, in the frequency of metastases nor in the frequency of tumors of other origin could be demonstrated. The parallels of chemotherapy in chemically induced liver cancer to clinical experience are discussed.

The cyclic chemotherapy scheme OS I/75 was tried in 6 patients with newly diagnosed osteosarcoma and in 3 patients with secondary metastases. The treatment consists of high dose methotrexate, followed by citrovorum-factor rescue, doxorubicine (Adriblastin) and cyclophosphamide (Endoxan). All 6 primary patients are in a continuous remission of 6+ to 21+ months (median 12+ months). The length of remission in the patients with metastases is 5.5+ and 8+ months. The haematological side effects led to an average prolongation of the cycle by 11 days in a planned cycle duration of 42 days. However, they were readily manageable. Among the other side effects two cases of Adriblastin myocardiopathy are remarkable which became apparent after methotrexate and ifosfamide. In order to improve possibilities for treatment regional centralisation of patient care and interdisciplinary and supraregional cooperation of treatment centres are necessary. A prospective treatment programme has been developed for the Federal Republic of Germany and Austria.

Six patients with osteosarcoma and no evidence of metastases received postoperative adjuvant chemotherapy with high-dose cyclophosphamide (25 mg/kg iv every other day for five doses). Three of these patients are alive without evidence of disease at 2 1/2, 3, and 5 years following diagnosis. The regimen was tolerable in terms of toxicity. Cyclophosphamide in high doses may be effective adjuvant therapy in some patients with osteosarcoma.

A randomized trial comparing Vincristine, Adriamycin, Cyclophosphamide (VAC) with or without Methotrexate with citrovorum factor rescue (VACM) was performed in 64 patients with metastatic postmenopausal mammary carcinoma. Previous treatment of metastases, dominant site of metastases and performance condition were similar in the patients. No significant difference was found in the response rates (complete remission + partial remission; VAC 21/31, VACM 25/33), in the duration of the remissions or in the survivals. The duration of remission in CR was significantly longer than in PR. No serious side effects were observed. The VAC regimen is preferable, particularly with respect to the costs and the simple procedure of administration.

The results obtained in 26 patients suffering from metastatic cancer of the breast no longer sensitive to hormone treatment are reported. The patients were treated with ciclophosphamide (CTX) (500 mg i.v.) once a week and triethylenethiophosphamide (20-30 mg i.m.) (TSPA) every 4 weeks associated with cyclophosphamide as follows: CTX--CTX--CTX--CTX+TSPA. 9 objective regressions (34.6%) were observed. Those with objective regression lived 28 months on average (SD 23.45) and those without lived on average 11.41 months (SD 9.89). The difference is statistically significant. Side effects of various types were observed in 7 patients (27%).

The results of treatment of 199 patients referred to the Royal Marsden Hospital with testiclar seminoma from 1963 to 1975 are described. Of 190 previously untreated patients 16 (8.4%) have died of seminoma, 3 (1.5%) of teratoma and 9 (4.9%) of intercurrent disease. Of 121 Stage I patients the only death was due to a second testicular tumour. In orchiectomy and volume of abdominal node metastases. This was not, however, prognostically significant. Death from seminoma occurred in 6 out of 38 patients (15.8%) with nodal metastases less than or equal to 5 cm in diameter and 3 out of 16 patients (18.7%) with metastases greater than 5 cm in diameter; 2 of 8 Stage III patients died of seminoma. Thus radiation controlled nodal metastases in more than 80% of Stage I, II and III patients. In Stage IV patients and patients referred with disease relapse, 12 out of 16 patients died of seminoma. Chemotherapy experience is briefly reviewed. Cyclophosphamide as a single agent has produced a 50% response rate. There is no evidence to suggest a radiation-related increase in mortality from the group of long-term tumour-free survivors.

Forty three children with testicular tumors have been presented. Eighty per cent of these tumors were malignant, and 60 per cent occurred in children less than two and one half years of age. Twenty of the 24 malignant germinal tumors were embryonal cell carcinomas. The mean age of the patients at presentation of these tumors was 18 months. Nine patients underwent orchiectomy alone, and five of these have died. Eleven received combined therapy, and all have survived. We currently recommend radical orchiectomy and extended unilateral retroperitoneal lymphadenectomy. If examination of the nodes reveals evidence of metastases, a bilateral dissection is done. Radiotherapy is given only in the presence of nodal metastases. Adjuvant chemotherapy with vincristine, actinomycin D, and Cytoxan is given for two years to all patients with malginant nonseminomatous germ cell tumors or sarcomas.

14 year old patient suffering from a renal cell carcinoma was treated by surgery and irradiation. 1 1/1 years after diagnosis he developed multiple metastases in the brain, skin, bones, and in regional lymph nodes. Cyclophosphamid and vincristin did not reduce the metastases. The literature is reviewed with regard to symptoms, diagnostic procedures, therapy, and prognosis of hypernephrome in childhood.
