Some therapeutic indications necessitate prolonged treatment with metronidazole. Peripheral neuropathy is a potential metronidazole-induced toxicity, which has been reported in only a few isolated retrospective studies. This prospective study was designed to determine the toxic profile of metronidazole in patients undergoing long-term treatment with this drug. In the present study, 17 patients of both sexes, aged between 20 and 50 years, with body weights ranging from 46 to 62 kg and who were suffering from various medical ailments were recruited. The patients received 400 mg t.i.d. oral metronidazole in a total dose of 16.8-39.6 g for 2-4 weeks. It was found that patients usually suffered from some of the toxic symptoms of metallic taste, headache and dry mouth and to a lesser extent nausea, glossitis, urticaria, pruritus, urethral burning and dark colored urine. Symptoms were irrespective of sex and directly proportional to duration of therapy. Deep tendon ankle jerks were maximally reduced in four patients and sense of vibration at the level of olecranon and patella was affected in two patients.

The aim of the present study was to establish whether decreasing the dosage of epirubicin to 150 mg/m2 would result in the same activity but with less hematological toxicity. One hundred fifty-nine patients with advanced soft tissue sarcoma were randomized for either epirubicin 150 mg/m2-cisplatin 120 mg/m2 (group A) or epirubicin 180 mg/m2-cisplatin 120 mg/m2 (group B). The results were as follows: group A: 79 patients were evaluated. Overall response rate was 24/79 (30%) (95% CI 21-41%). Median survival was 11 months and probability of survival at 1 year was 0.46. Grade IV granulocytopenia was present in 111/274 cycles and febrile neutropenia in 22/274. Group B: 73 patients were evaluated. The overall response rate was 39/73 (53%), (95% CI 42-64%). Median survival was 14 months and probability of survival at 1 year was 0.58. Grade IV granulocytopenia was present in 136/295 cycles and febrile neutropenia in 30/295. The differences were as follows: for overall response rate p = 0.004; power (for p = 0.05) 85%; for survival p = 0.09; for grade IV granulocytopenia p = 0.3; and for febrile neutropenia p = 0.61. A survival advantage (p = 0.043) was evident for patients randomized to group B and with performance status 0 or 1 compared with similar patients from group A. A plateau-like formation on the probability level of 0.26 on the survival curve started from month 26 onwards. In conclusion, both regimens share the same toxicity but epirubicin 180 mg/m2-cisplatin seems more active in soft tissue sarcoma, possibly indicating a breakthrough for activity between an epirubicin dosage of 150 mg/m2 and 180 mg/m2 in combination with cisplatin.
