Methotrexate has been shown to have a steroid-sparing effect in chronic steroid-dependent asthmatics at a dose of 15 mg week-1. The aim of this study was to investigate the steroid-sparing activity and adverse events profile of methotrexate 30 mg week-1 in severe steroid-dependent asthma. Eighteen patients who had required 10-50 mg week-1 prednisolone for at least 6 months were asked to participate in a randomized, double-blind, placebo-controlled cross-over study lasting 24 weeks. Daily diary cards of symptoms, peak expiratory flow rate and medication requirements were kept and the patients attended for a chest X-ray, spirometry, lung volumes and gas transfer at commencement and after each 12-week treatment period. Every 3 weeks, adverse events were noted and blood taken for full blood count, urea and electrolytes and liver function tests. Twelve patients completed the trial. Withdrawals were due to non-compliance in two patients, pneumonia in two patients, depression in one patient (on placebo) and severe nausea in one patient. Adverse events were common, probably as a consequence of the higher dosage. Prednisolone requirements were not significantly reduced on methotrexate. Lung function improved on methotrexate with a significant rise in maximal mid-expiratory flow rate and a trend towards improvement in FEV1.

153 women with advanced breast cancer were randomly allocated for treatment with SMF [prednimustine (Sterecyt) + methotrexate + 5-fluorouracil, 83 patients] or CMF (cyclophosphamide+methotrexate+5-fluorouracil, 70 patients). Prednimustine was administered orally 100 mg/m2 daily, for 5 days, and cyclophosphamide was administered orally 100 mg/m2, for 14 days, each, every 4 weeks. Methotrexate was given at a dose of 40 mg/m2 and 5-fluorouracil at 600 mg/m2 on day 1 and 8, every 4 weeks. Leucovorin was used in 39 patients to alleviate mucositis. The two treatment groups were balanced in terms of age, performance status, lymph node status, histology, menopausal status and previous therapy. Response was evaluated in 140 patients. Of 76 patients treated with SMF, 4 had a complete and 21 a partial response (CR+PR = 33%), 40 had no change (NC) and 11 had progressive disease (PD). Of 64 patients treated with CMF, 3 had a complete and 18 a partial response (CR+PR = 33%), 30 had no change (NC) and 13 had progressive disease (PD). Time to treatment failure and survival were similar in both groups. A relationship between haematological and gastrointestinal toxicity and therapeutic efficacy was demonstrated with a superior survival and response rate recorded for patients with such toxicity than in patients without. Haematological toxicity was, in general, mild to moderate with no difference between the two groups. Alopecia (P = 0.008), nausea/vomiting (P = 0.02) and euphoria (P = 0.03) were more common in the CMF-treated group. Diarrhoea was more common in the SMF group (P = 0.03). In conclusion, SMF seems to be as efficient as CMF with regard to response rate, time to treatment failure and survival. However, SMF was tolerated better than CMF.

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.

Methotrexate has been used as an anti-inflammatory agent in chronic asthma. We evaluated the action of methotrexate in eight corticodependent severely asthmatic children (more than 10 mg of prednisone per day for at least one year). The patients (3 males and 5 females; aged 8 to 14 years) received a single weekly dose of 0.6 mg/kg methotrexate (maximum 25 mg) and folic acid (15 mg/day for 5 days in the week). The children were examined and had their pulmonary function test evaluated weekly. As the study progressed, the dose of prednisone was reduced and maintained till the next evaluation if the patient's symptoms were under control. After the 3rd month of treatment, we observed a significant reduction in the dose of prednisone and maintenance of the spirometric parameters. At the end of the trial, in 4 patients it was possible to reduce the basal prednisone dose 56% or more. In the remaining 4, one did not show any benefit and in the other 3, it was possible to obtain an average reduction of 40% of the basal prednisone dose. The total mean reduction was 55.9%. This oral corticoid reduction was not associated with clinical or pulmonary function deterioration, except in one patient. The patients were submitted to white blood cell count, hepatic transaminases, urine tests and other determinations at least once a month. There were no changes in biochemical tests. The side-effects were nausea, vomiting and abdominal pain. In conclusion, methotrexate given to severely corticodependent asthmatic children permitted a reduction in the daily intake of prednisone, reducing the severe side-effects of chronic corticotherapy.

The pharmacokinetics and safety for early abortion of two intramuscular methotrexate doses were investigated in a randomized, controlled trial conducted at Magee Women's Hospital (Pittsburgh, Pennsylvania, US). The 20 study subjects, all with gestations under 50 days, were administered either 50 mg/sq. m (group 1, n = 10) or 60 mg/sq. m (group 2, n = 10). Methotrexate levels were measured serially for the first 24 hours and then every 24 hours for 7 days. On day 7, 800 mcg of misoprostol was administered vaginally and repeated 24 hours later if abortion did not occur. Complete abortion occurred in 9 women (90%) in group 1 and all 10 women in group 2. Success was immediate in 9 women in both groups. Methotrexate levels peaked within 1-2 hours and were nondetectable within 48 hours in all women in group 1 and within 72 hours in group 2. Both the maximum concentration of methotrexate and the area under the curve were significantly greater in group 2. Methotrexate clearance rates were 7.89 +or- 1.98 l/hr in group 1 and 5.55 +or- 0.83 l/hr in group 2. Methotrexate-related side effects included transient nausea, vomiting, diarrhea, headache, dizziness, and subjective fever or chills. Overall, these findings indicate both methotrexate regimens are safe treatment doses. A methotrexate dose of 50 mg/sq. m intramuscularly has the same clearance rates when administered during pregnancy as in a nonpregnant state and maximum concentrations do not reach sustained toxic levels.

Sequential chemotherapy with methotrexate and 5-fluorouracil (MTX/5-FU) for advanced gastric cancer was given 29 patients. The procedure consisted of weekly MTX 100 mg/m2 (i.v.) followed three hours later by 5-FU 600 mg/m2 (i.v.) with leucovorin rescue on each of the following two days. Nine of 28 patients (32.1%) showed partial response to this treatment. Response rates were 28.6% in the 21 cases with poorly differentiated adenocarcinoma and 42.9% in the 7 cases with well- or moderately-differentiated adenocarcinoma. This procedure was especially effective for primary lesions (PR 9/20: 45%) and lymphnode metastases (CR 4 + PR 4, 8/17: 47.1%). Side effects were mild leukopenia and G-I symptoms such as nausea, diarrhea and loss of appetite, except in 1 patient who died of severe myelosuppression with sepsis. We concluded that sequential MTX/5-FU therapy is fairly effective and the adjuvant chemotherapy of choice for advanced or recurrent gastric cancer with not only poorly differentiated adenocarcinoma but also well- or moderately-differentiated adenocarcinoma.

Osteosarcoma is one of the most common juvenile malignant tumors in Korea. Combined modality treatment (pre-operative chemotherapy + limb salvage surgery + adjuvant therapy) improved the patients' overall survival and quality of life. We evaluated the efficacy and feasibility of pre-operative chemotherapy with intra-arterial (IA) cisplatin plus continuous intravenous infusion (CI) of adriamycin. We assessed the rate of limb salvage, recurrence pattern and the survival impact based on the histologic response of pre-operative chemotherapy. Fourty-one patients with histologically-proven high grade osteosarcoma of the extremities were enrolled from January 1990 to June 1995. Pre-operative chemotherapy, cisplatin 120 mg/m2 IA and adriamycin 75 mg/m2/72 h CI was administered every 3 weeks for 3 cycles, followed by limb salvage surgery if possible or by amputation. According to the histologic tumor response, if the tumor necrosis was >90%, the same regimen was administered for 3 cycles as an adjuvant therapy. A salvage regimen (Ifosfamide 7.5 gm/m2/5 d IV + high dose MTX 10 gm/m2 IV+VP-16 360 mg/m2/3 d IV) was administered every 3 weeks for 6 cycles if the tumor necrosis was <90%. Of 41 patients, 37 patients were evaluable for efficacy and toxicities, because 4 patients refused chemotherapy after 1 or 2 cycles. Twenty-one patients were male and 16 were female with median age of 16 years (range 8-41). The tumor locations were: distal femur 20, proximal tibia 8, humerus 6, distal tibia 2 and 1 in proximal femur. All but one patient, who died of neutropenic sepsis, completed the planned pre-operative therapy. Of the 36 patients who received surgery, limb salvage surgery was possible in 30 patients (83.3%) and 27 patients (75%) showed a good response (grade III 10; 27.8%, grade IV 17; 47.2%). With a median follow-up of 23 months, 3-year disease-free survival rate was 54.7% and overall survival rate was 78.3%. Of the 15 patients who recurred, the major metastatic site was the lung. No operation-related mortality was observed. Most patients experienced grade III-IV nausea, vomiting and hematologic toxicities, which were reversible with supportive cares. Pre-operative chemotherapy with IA DDP+CI ADR followed by surgery showed 75% histologic tumor response rate, 83% limb salvage rate and 54.7% 3-year disease-free survival rate with tolerable side effects. To improve the survival rate, the possible role of good salvage chemotherapy with a non-cross resistance regimen in poor responders should be evaluated.

Methotrexate-albumin conjugate (MTX-HSA) is a novel human albumin-based prodrug conjugate of methotrexate (MTX). A low MTX loading rate provided optimal tumor targeting and therapeutic efficacy during preclinical testing. The objectives of this first Phase I study of MTX-HSA were to determine dose-limiting toxicity (DLT) and maximum tolerated dose (MTD) in a weekly regimen. Seventeen cancer patients who were no longer amenable to standard treatment were enrolled and were evaluable for DLT. Up to eight injections were performed in weekly intervals. Dose escalation was as follows: 20, 40, 50, and then 60 mg/m2 MTX-HSA (based on the amount of MTX bound to albumin). Additional MTX-HSA courses were feasible in case of tumor response. DLT (mainly stomatitis, Common Toxicity Criteria grade 3) occurred, beginning at the 50 mg/m2 dose level after repeated administrations; in one case, thrombocytopenia was dose-limiting. Two events of DLT occurred at the 60 mg/m2 dose level within the first two administrations. Mild anemia, transaminitis, and one case of skin toxicity were found. No significant leukopenia, nausea, renal toxicity, or other toxicities were observed. MTX-HSA was well tolerated. Drug accumulation occurred on the weekly schedule. The half-life of the drug was estimated to be up to 3 weeks. Tumor responses were seen in three patients: (a) a partial response was seen in one patient with renal cell carcinoma (response duration, 30 months, ongoing); (b) a minor response was seen in one patient with pleural mesothelioma (response duration, 31 months, ongoing); and (c) a minor response was seen in one patient with renal cell carcinoma (response duration, 14 months until progression). Poststudy treatment was administered at 2-4-week intervals. No signs of toxicity or drug accumulation were seen. Altered pharmacological properties of MTX-HSA such as plasma half-life, tumor targeting, or intracellular metabolism might have contributed to these responses. The MTD for weekly administration was 4 x 50 mg/m2 MTX-HSA during short-term treatment. A regimen with MTX-HSA injections of 50 mg/m2 every 2 weeks was recommended for a further clinical Phase I study.

In a prospective multi-centre collaborative study, 516 patients with advanced cancer were treated by epirubicin (pararubicin, EPI) containing regimens. After CEOP (cyclophosphamide CTX, EPI, vincristine VCR and prednisone PDN) was used in the treatment of 213 patients with non-Hodgkin's lymphomas, 87 patients had complete remission (CR) and 99 partial remission (PR). Their response rate was 87.3%. However, there were 2 CR and 71 PR in 161 patients with non-small cell lung cancer treated by CEP regimen (CTX, EPI and cisplatin PDD), with a response rate of 45.3%. In 70 breast cancer patients treated by EMF regimen (EPI, Methotrexate MTX and 5-fluorouracil 5-FU), 8 had CR and 28 PR, with a response rate of 51.4%. The EPI containing regimens were also effective in dealing with gastro-intestinal tract and nasopharyngeal cancers. Adverse effects of epirubicin containing regimens were mainly nausea and vommiting, and the dose-qlimit toxicity was leucopenia. Hepatic, cardiac and renal toxicities were rather mild. The current phase III study revealed that the effect of epirubicin is similar to that of adriamycin, but the cardiac toxicity is relatively mild. So the effects can be improved by increasing the dose-intensity.

The efficiency and toxicity of treatment regimens for nonintensive cytoreduction in 57 outpatients with refractory acute leukemia (mean age 56 years, 51 AML, six ALL/AUL) were retrospectively studied. Seventeen patients received one treatment regimen, 19 patients two treatment regimens, and 21 patients three or more treatment regimens. The treatment regimens analyzed were 6-thioguanine p.o. (daily) (T), 6-thioguanine p.o. (4-7 days/week) + cytarabine s.c./i.v. (once a week) (T+C), 6-mercaptopurine p.o. (daily) (MP), 6-mercaptopurine p.o. (daily) + methotrexate p.o./i.v. (once a week) (MP+MTX), etoposide p.o. (daily) (E), and mitoxantrone i.v. (M). The median leukocyte count was higher for M (73 x 10(9)/l) than for the other treatment regimens (T: 27 x 10(9)/l, T+ C: 37 x 10(9)/l, MP: 24 x 10(9)/l, MP + MTX: 30 x 10(9)/l, E: 31 x 10(9)/l). A cytoreduction >50% in the peripheral blood was achieved by T in 11/19, by T+C in 7/11, by MP in 5/8, by MP+MTX in 3/6, by E in 3/4, and by M in 16/22 patients. The period of cytoreduction was regarded as the duration of response - T: median 53 days, range 5-98; T+C: median 61 days, range 14-226; MP: median 37 days, range 4-192; MP + MTX: median 58 days, range 36-59; E: median 121 days, range 26-159; M: median 39 days, range 8-78. T and T + C were well tolerated by all but three patients (stomatitis, diarrhea, WHO grade 2). MP was accompanied by a rise of transaminases (WHO 1-3) in 5/6 patients. E led to stomatitis (WHO 1,2) in 4/5 and M to nausea/vomiting (WHO 1,2) in 5/22 and to stomatitis (WHO 2) in 4/22 cases. The mean survival time after start of palliative cytoreduction was 16 weeks (2-65). In summary, 6-thioguanine +/- cytarabine was best tolerated with effective but in oral monotherapy - often protracted cytoreduction in 60% of patients. Mitoxantrone showed tolerable side effects and potent cytoreduction in 73% of patients even after ineffective palliative pretreatment. Palliative cytoreductive therapy does not reduce the quality of life and can prevent complications of significant leukocytosis in refractory acute leukemia.
