Ifosfamide was administered to 21 patients with recurrent or disseminated lung cancer at a dose of 4.0 gm/M2 iv every 3 weeks. The response rate was 33% with an additional 14% showing no response or stable disease. At a dose of 1.2 gm/M2 daily for 5 days every 4 weeks, 57% of 14 patients responded with 35% showing no response or stable disease. The majority of the patients (28) had epidermoid carcinoma. Two (7%) had complete response with 9 (32%) showing partial responses. Other responses included 1/2 oat cell carcinomas and 3/6 large cell undifferentiated carcinomas. Toxicity was equal in both regimens for nausea, vomiting, increased serum LDH and neutropenia but the 5 day program had significantly less hemorrhagic cystitis. Survival was greatly influenced by response. There was no statistical difference in overall length of response between responders and the non responding/stable disease patients. But these two groups had a very significant survival advantage when compared to those patients with increasing disease. Similarly, there was a significant improvement in response duration for the low dosage regimen. Therefore, the low dose 5 day regimen is recommended because of its response rate, it has less hemorrhagic cystitis and it has better patient acceptance in that it can be given as an outpatient and does not require a Foley catheter.

Biological response modifiers (BRMs) have greatly modified the immunotherapy of tumors. Interleukin-2 (IL-2) has brought about metastasis regression in some cases of malignant tumors, however, when given systemically, it results in high toxicity. More recently, the subcutaneous administration of IL-2 (combined with alpha-interferon, alpha-IFN) seems to be capable of offering the same chances of therapeutic response, but this time with a lower level of toxicity. The Authors report an evaluation of toxicity in 22 patients treated with a combination of IL-2 + alpha-IFN i.m. with or without chemotherapy. The side-effects present in the majority of cases were: fever, diarrhea and asthenia. Approximately 50% of the patients had nausea/vomiting, mucositis, skin rashes, and slight leukopenia. The following side-effects were noted to a much lesser degree, thrombocytopenia, alterations in hepatic and dizziness and cystitis. Only one patient reached 4th degree toxicity, with mucositis, asthenia and skin rash. All the other patients received the treatment without suspensions for toxicity. Biological evaluations will enable us to determine in the future, the cases which can benefit from therapeutic intensification and thus it would seem opportune at this time to use therapy with acceptable toxicity.

Two different doses of cefaclor advanced formulation (AF), a new sustained-release formulation of cefaclor, were compared with the regular formulation of cefaclor for efficacy and safety in the treatment of uncomplicated cystitis and asymptomatic bacteriuria. A 7-day course of treatment was used, and the trials were double-dummy and double-blind. In one trial, cefaclor AF 500 mg once daily (at night) was compared with cefaclor 250 mg three times a day. Satisfactory clinical and bacteriological responses were found in 179/189 (94.7%) and 160/191 (83.8%) patients, respectively, given cefaclor AF and in 82/87 (94.3%) and 74/90 (82.2%) patients given cefaclor, 5-9 days after the end of treatment. In the other trial, cefaclor AF 375 mg twice daily was compared with cefaclor 250 mg three times a day. Satisfactory clinical and bacteriological responses were obtained in 164/180 (91.1%) and 156/184 (84.8%) patients, respectively, given cefaclor AF, and in 86/92 (93.5%) and 81/93 (87.1%) patients taking cefaclor, 5-9 days after the end of treatment. Very similar results were found in both studies in those patients who were assessable 3-5 weeks later. Only 4.3% and 2.4% of patients treated with cefaclor AF (375 mg and 500 mg, respectively) and 2.2% of cefaclor patients discontinued therapy due to adverse events. The three most commonly reported events were vaginal moniliasis or vaginitis (8.6%), headache (5.0%) and nausea (4.8%). No significant differences were found between clinical efficacy and safety parameters in the different study groups, and it was concluded that cefaclor AF in a twice-daily or once-daily dosage is as effective and as safe as the currently recommened three-times-a-day dosage of cefaclor.

In this double-blind study, 333 patients (16 males, 317 females) with cystitis or asymptomatic bacteriuria were randomly assigned to receive 200 mg of loracarbef once daily (n = 164; mean age, 36 years) or 250 mg of cefaclor thrice daily (n = 169; mean age, 37 years) for seven days. Cystitis was diagnosed in 97.8% of the evaluable loracarbef-treated patients and 94.4% of the evaluable cefaclor-treated patients. Clinical and bacteriologic responses were assessed in 92 loracarbef-treated patients and 107 cefaclor-treated patients. At the five- to nine-day posttreatment evaluation, a clinical cure was found in 84.5% of the loracarbef-treated patients and in 79.4% of the cefaclor-treated patients and improvement in 3.3% and 7.5%, respectively. The pathogen was eliminated in 76.1% and 72.9%, respectively; new pathogens were identified in 4.3% and 4.7%, respectively; and the original pathogen was not eliminated or recurred in 19.6% and 21.5%, respectively. Nausea was the most frequently reported adverse event (in 4.5% of all patients). The results indicate that both loracarbef and cefaclor are safe and effective in the treatment of uncomplicated urinary tract infections.

Ifosfamide is an oxazaphosphorine alkylating agent with a broad spectrum of antineoplastic activity. It is a prodrug metabolised in the liver by cytochrome P450 mixed-function oxidase enzymes to isofosforamide mustard, the active alkylating compound. Mesna, a uroprotective thiol agent, is routinely administered concomitantly with ifosfamide, and has almost eliminated ifosfamide-induced haemorrhagic cystitis and has reduced nephron toxicity. Therapeutic studies, mostly noncomparative in nature, have demonstrated the efficacy of ifosfamide/mesna alone, or more commonly as a component of combination regimens, in a variety of cancers. In patients with relapsed or refractory disseminated nonseminomatous testicular cancer, a salvage regimen of ifosfamide/mesna, cisplatin and either etoposide or vinblastine produced complete response in approximately one-quarter of patients. As a component of both induction and salvage chemotherapeutic regimens, ifosfamide/mesna has produced favourable response rates in small cell lung cancer, paediatric solid tumours, non-Hodgkin's and Hodgkin's lymphoma, and ovarian cancer. Induction therapy with ifosfamide/mesna-containing chemotherapeutic regimens has been encouraging in non-small cell lung cancer, adult soft-tissue sarcomas, and as neoadjuvant therapy in advanced cervical cancer. As salvage therapy, ifosfamide/mesna-containing combinations have a palliative role in advanced breast cancer and advanced cervical cancer. Ifosfamide/mesna can elicit responses in patients refractory to numerous other antineoplastic drugs, including cyclophosphamide. With administration of concomitant mesna to protect against ifosfamide-induced urotoxicity, the principal dose-limiting toxicity of ifosfamide is myelosuppression; leucopenia is generally more severe than thrombocytopenia. Reversible CNS adverse effects ranging from mild somnolence and confusion to severe encephalopathy and coma can occur in approximately 10 to 20% of patients after intravenous infusion, and the incidence of neurotoxicity may be increased to 50% after oral administration because of differences in the preferential route of metabolism between the 2 routes of administration. Other adverse effects of ifosfamide include nephrotoxicity, alopecia, and nausea/vomiting. In general, intravenously administered mesna is associated with a low incidence of adverse effects; however, gastrointestinal disturbances are common following oral administration. Thus, ifosfamide/mesna is an important and worthwhile addition to the currently available range of chemotherapeutic agents. It has a broad spectrum of antineoplastic activity and causes less marked myelosuppression than many other cytotoxic agents. At present, the role of ifosfamide/mesna in refractory germ cell testicular cancer is clearly defined; however, its overall place in the treatment of other forms of cancer awaits delineation in future well-controlled comparative studies.

N-Acetylcysteine is useful as a mucolytic agent for treatment of chronic bronchitis and other pulmonary diseases complicated by the production of viscous mucus. It is also used as an antidote to paracetamol (acetaminophen) poisoning and found to be effective for the prevention of cardiotoxicity by doxorubicin and haemorrhagic cystitis from oxazaphosphorines. After an oral dose of N-acetylcysteine 200 to 400 mg the peak plasma concentration of 0.35 to 4 mg/L is achieved within 1 to 2 hours. Although the data are conflicting, it appears that the administration of charcoal may interfere with drug absorption, with up to 96% of the drug adsorbed on to the charcoal. Information on absorption in the presence of food or other drugs is not available. The volume of distribution ranges from 0.33 to 0.47 L/kg and protein binding is significant, reaching approximately 50% 4 hours after the dose. Pharmacokinetic information is not available as to whether or not N-acetylcysteine crosses the blood-brain barrier or placenta, or into breast milk. Renal clearance has been reported as 0.190 to 0.211 L/h/kg and approximately 70% of the total body clearance is nonrenal. Following oral administration, reduced N-acetylcysteine has a terminal half-life of 6.25h. Little is known of the metabolism of this agent, although it is believed to be rapidly metabolised and incorporated on to proteins. The major excretory product is inorganic sulphate. Frequently reported side effects are nausea, vomiting and diarrhoea. Biochemical and haematological adverse effects are observed but are not clinically relevant. Drug interactions of clinical significance have been observed with paracetamol, glutathione and anticancer agents.

The Italian multihospital study of bacteriuria in pregnancy randomized 153 pregnant bacteriuric patients to receive fosfomycin trometamol (FT) as a single dose of 3 g and 138 such patients to receive conventional therapy with pipemidic acid (PA), 400 mg b.i.d. for seven days. The two groups were well matched for age, parity, pregnancy course, symptoms and past history of cystitis. Infecting organisms were eradicated in 147 (96%) of FT and 129 (94%) of PA patients. Similar recurrence rates occurred. Minimal side effects (mostly nausea and dyspepsia) occurred (9%) FT; 15% PA). Single-dose FT appeared equivalent to conventional treatment with PA.

An ongoing trial of combination chemotherapy using ifosfamide (Holoxan), epirubicin and 5-fluorouracil was started in 1987. A total of 30 patients with metastatic cancer of the breast received 1.5 g/m2 i.v. ifosfamide over 60 min on days 1-3, 50 mg/m2 i.v. epirubicin on day 1 and 500 mg/m2 i.v. 5-fluorouracil on day 1, followed by mesna (Uromitexan) given at 20% of the ifosfamide dose at 0, 4 and 8 h. The courses were repeated every 4 weeks. In all, 198 courses were given, ranging from 3 to 13 (median, 7) cycles/patient. The mean age of the 30 patients was 48 years (range, 35-66 years); 5 had not previously received chemotherapy and the others had failed prior cytotoxic and endocrine therapy. Overall, 28 patients were evaluable, 7 (25%) showed a complete response and 15 (54%) had a partial response, for an overall response rate of 22/28 (79%). Three patients showed stable disease with improved symptoms, and in three cases disease progression occurred. The median duration of response was 9 months (range, 3-20 months). Median survival was 11 months for all patients, 15 months for CRs, 10 months for PRs, 6 months for stable disease and 12 months for progressive disease (PD). Survival for the 22 responding patients was 12 months. Toxicity was acceptable and included alopecia, mucositis, nausea, vomiting, diarrhoea, mild cystitis and myelosuppression. Epirubicin did not appear to produce cardiac toxicity, and ifosfamide with mesna did not seem to result in severe urotoxicity. Chemotherapy with ifosfamide, epirubicin and 5-fluorouracil proved to be effective for treatment of advanced breast cancer and should be further studied in large, controlled trials.

Fourteen patients with refractory metastatic breast cancer were treated with high dose chemotherapy and autologous hematopoietic stem cell rescue. All patients received cyclophosphamide (7.5 g/m2 over 3 days) and thiotepa (150-225 mg/m2 over 3 days), three patients in addition received melphalan (4.5 mg/kg), and seven patients received carmustine (150-562 mg/m2). Toxicities included pancytopenia, infection, hemorrhagic cystitis, skin rash, nausea, vomiting, diarrhea, and mucositis. There was one toxic death secondary to sepsis and ventricular tachycardia. The overall response rate was 77% including a 15% complete response rate. The overall median survival for all patients was 6.0 months (range 2-22 months). The median survival for nonresponders was 3.5 months. The median duration of response was 89 days (range 40-262). In our experience high dose chemotherapy with autologous stem cell reinfusion produces a high response rate in refractory breast cancer. However, because of the short duration of response and overall survival, we feel this type of therapy should be utilized earlier in the course of disease.

Fifteen patients with Stage IV lung cancer both untreated and previously treated were enrolled into a high-dose chemotherapy program with multiple alkylating agents and autologous bone marrow reinfusion. Eight patients received cyclophosphamide at 7.5 gm/m2 over 3 days with thiotepa escalated from levels of 1.8 mg/kg to 6.0 mg/kg over 3 days. Seven patients received the above dose of cyclophosphamide plus thiotepa at 675 mg/m2 and oral melphalan escalated from levels of 0.75 mg/kg to 2.5 mg/kg over 3 days. Both regimens are part of larger Phase I-II clinical studies. The median time to recovery of more than 500 granulocytes and more than 50,000 platelets per microliter was 16 and 27 days, respectively. Two patients died as a consequence of severe, overwhelming infections during their period of aplasia. Of the 13 evaluable patients, no patients achieved a complete response and seven patients (47%) obtained a partial response. The median duration of response was 12 weeks. Other nonhematologic toxicities included nausea/vomiting, diarrhea, mucositis, skin rash, hemorrhagic cystitis, and cardiomyopathy. Since there are substantial toxicities associated with high-dose chemotherapy and responses of such brief duration, further investigation with these drug combinations is not warranted.
