Forty-three patients with disseminated germ cell cancer were treated with a combination of vincristine, Adriamycin, cyclophosphamide, actinomycin-D, and medroxyprogesterone acetate. All the 43 patients were considered evaluable for response. Thirty-one patients (72%) achieved a complete or partial remission and 14 (32.5%) achieved a complete remission. The patients who attained an objective response obtained a significant prolongation of life compared with the nonresponders (median survival 55 vs. 23 weeks). Responses were seen in all histologic categories and most frequently in patients with metastases confined to the lungs. The major side effects were leukopenia and stomatitis. There were no deaths related to toxicity of the chemotherapy.

The results of treatment of 23 children at the age of 7 months to 11 years suffering from neuroblastoma are presented; 22 patients with tumors, relapses or metastases were subjected to the treatment and 1 child was treated prophylactically after radical operation. Four patients were subjected to roentgen therapy in addition to the treatment with rubomycin. The antibiotic was administered intravenously in doses of 0.7--1.5 mg/kg in 1--3 days or daily. The caurse dose (3--12 mg/kg) was determined by the treatment efficiency and the side reactions. The objective effect was observed in 68 per cent of the patients, including the pronounced objective effect (marks 3 and 2) in 41 per cent of the cases. Leucopenia (less than 4000 cells in 1 mm3 of the blood). thrombocytopenia, vomiting (or nousea) and changes in the ECG were registered in 20 (87 per cent), 4,9 and 2 patients respectively. When the results of the treatment were positive, repeated courses of the therapy within 1.5--2 years were carried out; 18 patients died within 4 months to 2 years after the first course of the treatment with rubomycin because of the disease development. No signs of the disease were observed in 4 children with in 3--6 years of observation.

Despite the radiocurability of stage I and II squamous cell carcinoma (SCC) of the cervix, palliation of patients with pulmonary metastases has been disappointing. Four patients with pulmonary metastases (three from cervical and one from endometrial carcinoma) were treated with total lung irradiation, followed two to three weeks after termination of radiotherapy with combination chemotherapy consisting of vincristine 1.4 mg/m(2) IV+ adriamycin 50 mg/m(2) IV + cyclophosphamide 500 mg/m(2) IV repeated at four-week intervals. Radiotherapy was delivered through a Co(60) teletherapy unit in a daily dosage of 100 rads in anterior and posterior opposing fields. After completion of irradiation in one lung, the other lung was similarly treated if involved with gross disease. Two out of four patients (both with cervix SCC) obtained complete tumor regression, whereas the other two patients had stabilization of their pulmonary lesions. The survival of the two responders was 216+ and 621 days from the start of irradiation. The two nonresponders survived 56 and 109 days. Except for one patient who died of pulmonary metastases, the remaining three patients died of metastases elsewhere. While only one patient developed radiation pneumonitis, all four had alopecia and leukopenia <4000/mm(3) from chemotherapy. Total lung irradiation and combination chemotherapy appear to have activity in the treatment of pulmonary metastases from SCC of the cervix and warrant further exploration.

MCCNU and cyclophosphamide are synergistic in animal tumor systems and have different chronology patterns for dose-limiting myelosuppression. The combination was employed in 49 patients with metastatic cancer with each drug administered on successive days and repeated at 6-week intervals. A total of 108 courses of therapy were monitored, and leukopenia (WBC less than 3,000 cells/mm3) and thrombocytopenia (platelets less than 150,000/mm3) were observed in 47 and 30%, respectively, at nadir days 15 and 22. No clinically beneficial effects were observed in 40 patients with measurable disease. Combination chemotherapy employing nitrosoureas have not, as in this study, generally demonstrated synergistic therapeutic effects possibly related to the low level of antitumor activity of nitrosoureas in solid tumors and the use of suboptimal doses for one of more agents in the combination.

Studied were clinically and paraclinically six cattle manifesting an experimental suppurative surgery infection caused by Cornebacterium pyogenes, strain 1056. It was established that the infection assumes the course of septicaemia with metastases in the viscera, causing severe disturbances in the general condition and leading to death in most cases. Found were also anemia, leukopenia, that alternated with leukocytosis presenting nuclear shift to left, changes in the erythrocyte sedimentation rate in terms of more rapid settling out of r. b. c. The urine presented protein and sediment consisting of 8 to 10 or numerous erythrocytes, 5 to 6 or 10 to 15 leukocytes, single to 8-10 kidney epithelium cells. The rumen content became alkaline, and the infusoria count dropped.

In 409 sufferers from various malignant tumours, we used the cytostatic Ifosfamide (ASTAZ4942) in fractionated doses. The total i.v. dose averaging 300 mg/kg bodyweight, was either spread over 5 consecutive days (5 X 60 mg/kg i.v.) or over 10 consecutive days (10 X 30 mg/kg). At the same time, most patients were irradiated, the radiation dose usually being only one tenth the antitumour dose. Infections and electrolyte imbalance were first treated before Ifosfamide therapy was instituted. Cases of advanced cerebral sclerosis, thrombopenia below 75,000/cmm, cerebral metastases, impaired renal function and inadequate cooperation of the patient were excluded from the studies. To prevent and control side effects, various premedications and adjuvants are required: Antiemetics, prevention of cystitis and infections, cardiovascular agents etc. Corticosteroids are contraindicated. Out of 360 assessable patients 101 had a full remission, 150 a partial remission, 79 were failures; 30 cases were not evaluated. Good results were seen especially in ovarian carcinoma, mammary carcinoma and microcellular bronchial carcinoma. Particularly striking is the drug's effectiveness in testicular tumours including teratomas, osteosarcomas, chondrosarcomas and myosarcomas as well as in some adenocarcinomas of the gastro-intestinal tract, particularly pancreatic carcinoma. In lymphoreticular tumours and haemoblastoses, its potency is less pronounced. The side effects of Ifosfamide are the same as those of other alkylating agents. They are reversible and can usually be controlled or even avoided by adequate preventive measures. In the order of incidence we observed: Alopecia, leukopenia, fall in haemoglobin, cystitis, intercurrent infections, nausea and vomiting as well as cerebral disorders. Since haemorrhagic cystitis considerably interferes with Ifosfamide treatment, its prevention is of essential importance. Because of possible complications and specific premedication and adjuvant measures for their control, this type of treatment should for the present only be carried out by oncologists or special cancer centres.

119 patients with metastatic melanoma received fotemustine 100 mg/m2 on days 1 and 8 and dacarbazine 250 mg/m2 on days 15-18. After a 5-week rest, fotemustine 100 mg/m2 on day 1 and dacarbazine 250 mg/m2 on days 2-5 was given every 3-4 weeks. 12 complete responses (11.6%) and 16 partial responses were observed in 103 evaluable patients (response rate 27.2%). The median duration of response was 21.5+ weeks (8+ to 53+). The response rate was 26.3% in CNS, 18.2% in visceral sites and 37.5% in non-visceral sites. The toxicity was mainly haematological: grade III-IV leukopenia in 27.4% and thrombocytopenia in 23.4%. The response rate was lower than that in 63 patients previously reported. The present series had a higher median age (54 vs. 40 years) without any differences in other population variables. However, activity on CNS metastases and on non-visceral sites was confirmed. Haematological toxicity was about 50% lower than that with fotemustine alone. Hence, this is an active outpatient regimen for metastatic melanoma, especially against cerebral and non-visceral metastases.

A total of 12 patients with advanced renal cell carcinoma received interferon alpha (3 million units intramuscularly 6 times weekly) and OK-432 (5 KE (Klinische Einheit) intramuscularly twice weekly). Metastatic lesions appeared before operation in six patients and after operation in six patients. Among them 5 patients had received interferon therapy and this combination therapy was started after the judgment of progressive disease for interferon therapy. Eleven pulmonary and 5 bone metastases were evaluable. The median duration of the combination therapy was 89.3 weeks. There were 4 partial responses and no complete responses among the 12 patients, giving a response rate of 33.3%. The median duration of response was 25 months, with a range of 6 to 54 months. Responses were seen predominantly in patients in whom metastases appeared after operation (3 of 4 responders). However, regarding the individual organs, two complete and 2 partial responses were observed among 11 pulmonary metastases and 2 partial responses among 5 bone metastases. The survival period after discovery of the metastasis was 10 to 67 months and the 5-year survival rate was 70.5%. Almost all patients had fever and induration at the injection site. Other side effects included leukopenia, anorexia, and depression. This combination therapy is thought to be effective against bone or other organs metastasis resistant to interferon alone.

Twenty-seven metastatic breast adenocarcinoma patients, pretreated with standard hormonotherapy or chemotherapy, received carboplatin 100 mg/m2/day x 3 intravenously (i.v.) plus etoposide 100 mg/m2/d x 3 i.v. repeated at 4-week intervals. There were five partial responses (18.5%), two minor responses, and 12 disease stabilizations. The dominant metastatic disease sites were soft tissue in three partially responding patients and visceral metastases in the two remaining responders. The median duration of response and time to progression were, respectively, 10 and 26 weeks. Major toxicity was myelosuppression with 85% of patients developing leukopenia; 48%, anemia; and 30%, thrombocytopenia. Carboplatin plus etoposide has shown antitumor activity in our group of pretreated patients. Based on the same schedule, a first-line carboplatin plus etoposide Phase II trial has been started.

Interleukin 2 (IL-2) mediates the regression of metastatic cancer but clinical use has been limited due to associated toxicities. Tumor necrosis factor (TNF) is an important mediator of IL-2 toxicity and may have a limited role in IL-2 antitumor efficacy. Because pentoxifylline (PTXF) inhibits TNF production, we hypothesized that PTXF would ameliorate IL-2 toxicity without compromising antitumor efficacy. Four groups of female C57BL/6 mice with pulmonary metastases from a 3-methylcholanthrene-induced fibrosarcoma (MCA-105) and four groups of nontumored mice were treated every 6 h for 4 d by intraperitoneal injections of either IL-2 alone, IL-2 and PTXF, PTXF alone, or equal volumes of saline. Upon completion of therapy, we found that PTXF suppressed many of the IL-2-induced effects including TNF production, lymphocytic infiltration of multiple organs, multiple organ edema, hepatic dysfunction, leukopenia, and thrombocytopenia. Tumor response was determined 21 d after cessation of therapy by quantitating the number and surface area of pulmonary metastases. PTXF preserved antitumor efficacy while reducing the morbidity and mortality caused by IL-2 treatment. These data strongly support the use of PTXF in extending the therapeutic index of IL-2 in the treatment of cancer.
