Twenty-three patients with histologically proven bronchogenic carcinoma of the lung were treated with regimen consisting of 3 intravenous doses of 0.4 mg/kg of MTX and intravenous infusion of 30-50 mg/kg body weight of CPM. Interval between 1st and 2nd dose of MTX, which served as synchronizing agent in phase G1/S, was 12 hrs, and interval between 2nd and 3rd dose -- 6 hrs. Infusion of CPM, which was considered to be a preferably S-phase killer was started simultaneously with administration of 3rd dose of MTX. Such courses were repeated every 21-30 days. Objective responses were noted in 10 of 19 adequately treated patients. MTX-CPM favourably influenced survival of the responders. The therapy was, however associated with a number of adverse reactions, from which neutropenia and complicating bacterial infections were particularly dangerous.

Of 19 patients with advanced transitional bladder cancer (T2-T4, N0-N+, M0) who received two or three cycles of pre-emptive MVC (Methotrexate, Vinblastine, Cisplatin), pathological partial (PR) and complete (CR) remissions were observed in 67% (50% and 17% respectively). The toxicity of chemotherapy was generally acceptable but 5 patients required hospitalization for neutropenia and thrombopenia . In one of them chemotherapy was stopped for severe sepsis. No death was observed. In 11 patients follow-up is greater than 12 months. In this group, 10 patients are actually alive and disease-free, while the other one was dead owing to brain metastasis, after eight months from surgery.

The purpose of this study was to evaluate the response rate, methotrexate plasma levels, and toxicity of a three-drug regimen in patients with gastric carcinoma. A total of 37 patients with advanced measurable adenocarcinoma of the stomach were treated with Adriamycin, methotrexate, and 5-fluorouracil (AMF). Adriamycin and methotrexate were given as i.v. infusions on day 1; 24 h following methotrexate administration, patients received an i.v. infusion of 5-fluorouracil concomitantly with oral leukovorin factor (given over 48 h). Methotrexate levels were monitored regularly in all patients, and courses were repeated every 3 weeks. The median dose levels per course were 50 mg/m2 (range, 40-60 mg/m2) for Adriamycin, 1,000 mg/m2 (range, 650-1,250 mg/m2) for 5-fluorouracil, and 500 mg/m2 (range, 160-625 mg/m2) for methotrexate. Of 36 evaluable patients, 8 (22%) achieved an objective response, including 1 complete remission. Stable disease was noted in 11 patients and a minor tumor regression occurred in 1. The median survival duration of all patients was 6 months (range, 2-31+ months). AMF was well tolerated; toxicities were mild to moderate, most frequently involving nausea and vomiting, mucositis, and neutropenia with or without fever. There was no death directly attributable to chemotherapy. Although the AMF regimen used a well-documented preclinical concept of synergism between methotrexate and 5-fluorouracil, response and survival results suggest a modest activity of this combination in patients with gastric cancer. Better preclinical models are necessary for the development of effective combination chemotherapy.

A total of 23 patients with advanced gastric adenocarcinoma were treated with a combination of moderate-dose methotrexate (MDMTX), 250 mg/m2 i.v., with folinic acid rescue and 5-fluorouracil (5-FU) 600 mg/m2 i.v. Therapy was given every 7 days for 4 courses and then at 14-day intervals. All patients were evaluable for response. No complete responses occurred, but five patients (22%) had partial remissions (95% confidence limit, 5%-39%). The median duration of remission was 6 months, with a median survival of 11 months amongst responding patients. In all, six patients (26%) had stable disease for a median period of 5 months. The overall median survival was 6 months. Therapy was generally well tolerated, with principal toxicities consisting of neutropenia, nausea and vomiting, mucositis and diarrhoea. In terms of activity or survival in advanced gastric carcinoma, the combination of moderate-dose MTX and 5-FU does not appear to offer an advantage over single-agent therapy.

The efficacy of two chemotherapy regimens for recurrent and inoperable squamous cell carcinoma of the head and neck is reported. All patients had failed prior surgery and/or radiotherapy. 23 patients (group A) were treated with Cisplatin 120 mg/m2 and Adriamycin 60 mg/m2. 21/23 were evaluable for tumour response. The overall response rate (RR) was 28.5% (6/21, 2 CR and 4 PR). Methotrexate 250 mg/m2 with Leucovorin-Rescue 5 X 10 mg/m2 and 5-Fluorouracil 600 mg/m2 were administered to 28 patients. In 26 evaluable patients a RR of 38.4% (10/26, 5 CR and 5 PR) was achieved. The responders in groups A and B had a median survival of 98 and 85.5 weeks respectively and the non-responders 27 weeks in both groups. Nausea, vomiting and alopecia were common and severe in the DDP/ADM group. The major toxic effect of MTX/5-FU was neutropenia with two associated deaths from septicemia, although subjective side-effects were almost completely absent. MTX/5-FU can be recommended for the palliative treatment of recurrent squamous head and neck cancer because of an acceptable response rate, good subjective tolerance and the possibility of outpatient treatment.

Administration of the mucopolysaccharide, carrageenan (CAR), into the hind paw of the rat or mouse induces a local inflammation characterized by increased arachidonic acid metabolism, increased vascular permeability, edema, and neutrophil extravasation. Carrageenan-induced hind-paw inflammation is inhibited by prostaglandin synthesis inhibitors, and this assay predicts the clinical success of anti-inflammatory agents in reducing peripheral inflammation. The purpose of this study was to determine if intraventricular injection of CAR would induce brain inflammation similar to that evoked by CAR in peripheral tissues. The present study demonstrates that CAR injection into the ventricles of the mouse brain does in fact induce an inflammatory response very similar to that caused by injection of CAR into the peripheral tissues. The brain response to CAR was dose-dependent, with the maximum increase in cerebrovascular permeability to iodine-125-labeled human serum albumin and percent brain water occurring after injection of 50 micrograms CAR. As is seen in CAR-induced inflammation of the hind paw, the maximum increase in brain vascular permeability occurred 4 hours after CAR injection. Histological analysis of brains 4 hours after CAR administration showed global neutrophil extravasation into the subarachnoid space and evidence of focal neuronal swelling. Methotrexate-induced neutropenia, however, failed to diminish the permeability response to CAR. Gas chromatographic and mass spectrometric measurements of brain prostaglandins 4 hours after CAR injection revealed a significantly increased level of 6-keto-prostaglandin F1 alpha. These results indicate that a significant increase in prostacyclin, the pro-inflammatory arachidonic acid metabolite, during CAR-induced brain inflammation is likely. These studies suggest that CAR-induced brain inflammation may be a useful model on which to test the efficacy of anti-inflammatory agents in the brain, as well as providing information concerning the mediators and mechanisms by which the brain may sustain inflammatory injury.

M-VAC (Methotrexate, vinblastine, adriamycin and cisplatin) combination systemic chemotherapy is useful for treating invasive or metastatic transitional cell carcinoma. Granulocytopenia is the major dose-limiting factor of this chemotherapy and it takes 4 weeks or more to complete a single course of M-VAC. We have tried to shorten the period of M-VAC chemotherapy from 4 to 3 weeks by using rhG-CSF. With this modified M-VAC regimen, the number of days on which the absolute neutrophil count was less than 1000/mm3 was significantly reduced and the period to reach the neutropenia nadir was shortened. No severe side-effects were observed. In all patients treated with 2 courses of this modified M-VAC short regimen, the period of hospitalization could be reduced by 2 weeks. We emphasize the possibility of shortening the M-VAC regimen.

The association of large granular lymphocyte leukemia (LGL-L) with hepatocellular carcinoma in a 55-year-old patient is described. An increased number of LGL was seen on peripheral blood smears. The immunophenotype was CD3+, CD4-, CD8+, and a study of the TCR gene rearrangement indicated the monoclonal nature of the proliferation. A liver mass was detected on CT scan and an ultrasound-guided fine needle biopsy revealed the presence of hepatocholangiocellular elements. A right hepatectomy was performed. Major neutropenia persisted despite corticosteroids and granulocyte colony-stimulating growth factor (G-CSF) therapy. Methotrexate at 20 mg/week failed to control lymphocytosis after three months of treatment. A new nodule of hepatocarcinoma reappeared twelve months after surgery and a liver resection was performed.

An 8-year-old boy with combined IgG1 deficiency and neutropenia underwent allogeneic BMT from his HLA-identical, MLC-negative sister, because immunoglobulin (Ig) infusions and prophylactic antibiotics failed to prevent life-threatening infections. Conditioning was with busulfan and cyclophosphamide, MTX and CYA were given for the prophylaxis of GVHD. For 16 months after BMT no serious infections have occurred and serum IgG1 levels have returned to the normal range without Ig replacement. BMT may be appropriate treatment for patients with IgG subclass deficiency who rarely respond to conservative therapy.
