We conducted a Phase II study of combination therapy with vincristine and cyclophosphamide in the treatment of patients with recurrent or metastatic medulloblastoma. Fourteen patients were treated with vincristine 2 mg/m2 (2.0-mg maximal dose) by intravenous bolus on Day 1 and cyclophosphamide 1 g/m2 by intravenous infusion on Days 1 and 2, with cycles repeated every 4 weeks. All 4 patients with extraneural disease (biopsy-proven bony metastases) responded (duration of responses 2+, 6+, 8, and 16+ months) and 4 of 8 evaluable patients with neuraxis disease responded (duration of response 2, 2+, 2+, and 21+ months). Toxicity was limited to neutropenia without any episodes of infection. These therapeutic results compare favorably with other reports of therapy for recurrent medulloblastoma and support the inclusion of vincristine and cyclophosphamide in randomized adjuvant therapy trials of patients with medulloblastoma.

Four children with yolk sac tumor were treated with an aggressive combination chemotherapy program. Three children had presacral primary tumors, one having pulmonary metastases, and one had a testicular primary tumor with pulmonary metastases. Three children were treated when they had measurable disease, and one had no measurable disease. The chemotherapy program consisted of a 6-wk induction period with vincristine (VCR), cis-diamminedichloroplatinum (DDP), and bleomycin. Maintenance therapy consisted of VCR, actinomycin D, and cyclophosphamide (cytoxan) every 3-4 wk as tolerated. Treatment was discontinued after 12 mo of complete remission. All three patients with evaluable disease had a partial response (PR) to induction therapy. Two underwent surgical exploration following induction therapy, one a laparotomy and the other a thoracotomy, and were found to have only scar tissue at the sites of presumed residual disease. The third child with measurable disease progressed to a clinical complete response (CR) during maintenance therapy. Two patients have had no evidence of disease (NED) for 42+ and 41+ mo since starting therapy (28+ and 27+ mo since completing treatment). Two patients are NED 11+ and 7+ mo since starting therapy and remain on treatment. We have encountered no significant renal or pulmonary toxicity, and there have been only two hospitalizations during maintenance therapy for fever and neutropenia. These preliminary results employing different induction and maintenance chemotherapy programs and planned second-look surgical intervention appear encouraging.

After stratification for extent of small cell lung cancer, 109 patients were randomized to receive cycles of chemotherapy with cyclophosphamide, doxorubicin, and VP-16-213 [CAVP16 (regimen I)] or to receive CAVP16 to maximum response (minimum of three courses) and then chemotherapy with CCNU, methotrexate, vincristine, and procarbazine (COMP) alternating with CAVP16 (regimen II). A group of patients who achieved complete remission were randomized to receive whole-brain irradiation or to have observation only. Of the 44 patients with limited disease, 28 (64%) achieved a complete remission and 11 (26%) achieved a partial remission. Of the 65 patients with extensive disease, 26 (40%) achieved a complete remission and 28 (46%) achieved a partial remission. There were no significant differences between the regimens in response or survival. The projected median survival times are 14 and 10 months for limited and extensive disease, respectively. Nearly 30% of patients with limited disease will be 2-year, disease-free survivors. Twenty-nine patients were randomized to receive cranial irradiation or observation only; none of the 15 irradiated patients developed cerebral metastases, but five of 14 randomized to observation relapsed in the brain (P = 0.02). One patient died with necropsy evidence of only intracranial disease. The principal hematologic toxic effect was leukopenia. There were 31 febrile episodes (21 infectious) during neutropenia and four toxic deaths. Nonhematologic toxicity was mild. Cranial irradiation in patients who achieve complete remission delays or reduces the incidence of CNS metastases. Although alternating chemotherapy is not beneficial, combination chemotherapy with CAVP16 alone is highly effective treatment modality for small cell.

Mebendazole, its fluorine analogue flubendazole, and other benzimidazole derivatives are active against many gastrointestinal and tissue-stage helminths. This article reviews the published literature and proceedings of a workshop on the use of benzimidazoles against larval echinococcosis (hydatid disease). Orally administered high doses (30-50 mg/kg body weight) of mebendazole given daily for 20-90 days to rodents or sheep infected with larval Echinococcus granulosus cause damage of destruction of the cyst wall, loss of cyst fluid, and death of protoscolices. Similar treatment of rodents infected with E. multilocularis with mebendazole, flubendazole, fenbendazole, and albendazole for 60-300 days leads to reduction of weight, inhibition of growth and the metastases formation of E. multilocularis tissue, and to prolonged host survival time although the metacestodes are not killed. Mebendazole or flubendazole treatment of human patients infected with E. granulosus is followed by subjective improvement in most, and evidence of regression of cysts in some; in other patients, cysts continue to grow or have been proven viable even after several months of high-dose mebendazole therapy. In patients infected with E. Multilocularis, the progressive course of the disease appeared to be arrested, but treatment apparently did not kill the parasite. Side effects of some patients have included allergic reactions, alopecia, and reversible neutropenia. Some possible reasons for different responses to treatment include inadequate plasma drug absorption from the gut and age, condition, and location of cysts. Many remaining questions concerning the risk versus benefits of mebendazole therapy can be answered only through controlled clinical trials.

Between January 1973 and October 1977, 166 patients who died of breast cancer were autopsied. The examination revealed consistently more tumor involvement than had been clinically suspected. Unsuspected areas of tumor involvement included the endocrine organs (40%), lungs (28%), cardiovascular system (21%), and the genitourinary system (21%). The error in diagnosis was smaller with metastasis to the bones (10%) and central nervous system (14%). The major causes of death included pulmonary insufficiency (26%), infection (24%), cardiac disease (15%), hepatic insufficiency (14%), hemorrhage (9%), central nervous system disease (9%), and hypercalcemia (3%). The most common cause of death was metastatic disease to various organs, accounting for 42% of all deaths. Infection was the second most common cause of death; however, only 27% of the patients with infection had significant neutropenia. In patients dying of hemorrhage, only 9% were thrombocytopenic. In conclusion, although many clinicians have expressed concern that chemotherapy would add to early mortality in cancer, our study shows that this is not the case for patients with breast cancer. Deaths due to chemotherapy were rare and the rise in the infection rate did not correlate with the advent of chemotherapy.

The objective of this phase I trial was to determine the maximal tolerated dose (MTD) of Taxol and doxorubicin administered as a simultaneous intravenous infusion over 72 hours every 21 days. Granulocyte-colony stimulating factor (G-CSF) 10 micrograms/kg, was administered on days 4-18 of each cycle. The treated population consisted of metastatic breast cancer patients previously untreated with chemotherapy for metastatic disease, who had not received doxorubicin in the adjuvant setting and who had bidimensionally measurable disease. The MTD was determined to be 75 mg/m2 of doxorubicin and 160 mg/m2 of Taxol. The dose-limiting toxicity of the combination was clinical typhlitis in three of three patients. Other significant toxicities included grade 3 diarrhea at the higher dose levels and grade 4 neutropenia in all patients. Eighteen patients were treated on this initial phase I study. The overall response rate was 62%, with 6% complete responses and 56% partial responses. The combination of doxorubicin and Taxol by 72-hour continuous infusion with G-CSF is an active regimen in patients with metastatic breast cancer.

Clostridium septicum bacteremia is frequently associated with hematologic and colonic malignancies and neutropenia. It frequently produces 'metastatic' gangrene with excessive mortality. Standard therapy usually includes surgical debridement and antibiotics. We present a patient with metastatic breast cancer treated with high-dose chemotherapy and bone marrow transplantation. She was treated successfully with antibiotics alone despite developing Cl. septicum bacteremia and gas in hepatic metastases. The pathophysiology of this infection is reviewed.

The combination of mitozantrone, methotrexate and mitomycin (3M) gives a response rate of around 50% in patients with advanced breast cancer. The predominant toxicity is haematological. In this study, previously untreated patients were given 3M with increasing doses of mitozantrone (7-14 mg m-2) with recombinant human granulocyte colony-stimulating factor (metHuG-CSF) (filgrastim) to prevent marrow toxicity. Doses administered were 7 mg m-2 mitomycin i.v. 6 weekly, methotrexate i.v. 35 mg m-2 (maximum 50 mg) 3 weekly and mitozantrone i.v. 3 weekly as follows: 7 mg m-2, six patients (group 1); 10 mg m-2, six patients (group 2); 12 mg m-2, six patients (group 3); 14 mg m-2, six patients (group 4); all on day 1 for six cycles at the assigned dose. All patients received filgrastim (Amgen 0.3 mg ml-1) at a dose of 5 micrograms kg-1 subcutaneously daily on days 4-17 of each cycle. All treatment was given on an out-patient basis. A total of 24 patients were entered into the study. The median age was 63 years (range 48-75). ECOG performance status was 0 in ten, 1 in 11 patients and 2 in three patients. Locoregional disease alone was present in seven patients. The remainder had one or more sites of metastases. The actual dose administered to the 24 patients was as follows. The six patients in group 1 all completed six courses of treatment as per protocol. In group 2, three patients completed six courses, two stopped because of toxicity after one and four courses and one had progressive disease after one course. In group 3, three patients completed and three stopped early because of progressive disease. In group 4, two patients completed, one progressed after four courses and three responding patients stopped treatment because of toxicity. The maximum tolerated dose of mitozantrone in the 3M combination was 12 mg m-2. The use of filgrastim with increasing doses of chemotherapy prevents neutropenia, but other toxicities, namely thrombocytopenia and lethargy, then become dose limiting.

The use of preoperative chemotherapy with mitomycin, vinblastine and cisplatin (MVP) has led to improved complete resection rates and survival in Stage IIIA non-small cell lung cancer with bulky, ipsilateral, mediastinal lymph node metastases (Clinical N2 disease). The addition of preoperative irradiation has also been explored with results not substantially different from preoperative cisplatin-based chemotherapy alone. While preoperative chemotherapy has been shown to be feasible, the toxicity of both the chemotherapy and the subsequent resection is of concern with an overall treatment-related mortality of nearly 8%. The careful selection of patients, swift management of neutropenia, and meticulous perioperative pulmonary care has the potential to reduce the mortality from multimodality therapy. Having shown survival benefit in multiple single-institution and randomized trials, induction chemotherapy followed by surgery or irradiation is now the treatment of choice for patients with Stage IIIA non-small cell lung cancer with mediastinal lymph node metastases.

The combination of 5-fluorouracil (5-FU) and folinic acid (FA) has demonstrated activity in colorectal cancer (CC). Cisplatin is reported to have synergistic activity with 5-FU. We examined the combination FA + 5-FU + cisplatin in patients who had previously received chemotherapy with FA + 5-FU and relapsed. Two months after the last dose of FA + 5-FU and documentation of relapse, patients continued with the regimen consisting of cisplatin 20 mg/m2 in 15 min i.v. infusion followed by FA 500 mg/m2 in 1 h i.v. infusion, in the middle of which 5-FU 500 mg/m2 i.v. bolus was administered, with adequate post-hydration. This was repeated weekly for 4 weeks followed by a 2 week rest, for a maximum of six cycles. A total of 30 patients with CC that had relapsed to the combination of FA + 5-FU were treated; 23 had previous surgery and none had radiotherapy. Local recurrence was found in eight patients, metastases in the liver in 21, in lymph nodes in six, lung six and peritoneal metastases in seven. Seven patients responded partially. Toxicity requiring dose reduction or discontinuation of treatment included neutropenia 42% (grade 3:7%), mucositis 28% (grade 1:2), diarrhea 63% (Grade 3:10%), nausea-vomiting 55% (Grade 3:10%), increased creatinine value in three patients and peripheral neuropathy in two patients. We conclude that evaluation of this regimen shows substantial toxicity, with satisfactory response as a second line chemotherapy in these heavily pretreated patients.
