We performed a dose escalation study to evaluate the maximum tolerated dose of paclitaxel (Taxol; Bristol-Myers Squibb Company, Princeton, NJ) given over 3 hours plus bolus epirubicin 90 mg/m2. The starting dose of paclitaxel, 135 mg/m2, was escalated by 20-mg/m2 increments in cohorts of three to six patients. Courses were repeated every 3 weeks. Filgrastim (5 micrograms/kg/d) was administered to shorten the duration of grade 4 neutropenia lasting longer than 72 hours. Twenty-nine patients have been treated, 86% of whom had failed adjuvant chemotherapy (with anthracyclines in 14 cases). One hundred forty-eight courses have been administered, and the paclitaxel dose has been escalated to 225 mg/m2 without reaching the maximum tolerated dose. The most frequent dose-related toxicity has been grade 4 neutropenia, which occurred in 59% of courses. The median duration of grade 4 neutropenia was 4 days, which was shortened with filgrastim only in patients treated with paclitaxel 225 mg/m2. Eleven episodes of febrile neutropenia (7% of courses) have been observed. Nonhematologic toxicities were mild or moderate: grade 1 or 2 peripheral neuropathy was reported by 41% and 10% of patients, respectively. The cardiac toxicities of this regimen were surprisingly low: median left ventricular ejection fraction was 57% at study entry and 56% after six courses. Only two patients showed a decrease of left ventricular ejection fraction below 50% after six courses, and no signs of anthracycline-induced congestive heart failure were noted. The activity of this novel combination is encouraging: the overall response rate is 80%, with 16% complete responses. We have demonstrated that the combination of epirubicin plus paclitaxel given over 3 hours is feasible with acceptable toxicities, does not appear to be associated with clinically relevant cardiotoxicity, and is active in a population of patients who have failed adjuvant chemotherapy.

Several pathogenetic factors such as peripheral neuropathy, vasculopathy and infection are responsible for the development of diabetic foot ulcerations. An important factor contributing to the high infection risk in diabetic patients is a defect in neutrophil granulocytes. Deficiencies in neutrophil chemotaxis, phagocytosis and respiratory burst activity with the decrease of the super- and peroxids are known to be associated with diabetes. Granulocyte-colony stimulating factor (G-CSF) increases the release of neutrophils from the bone marrow and improves neutrophil function. A 78-year old patient with non-insulin-dependent diabetes presented with ulcerations of both big toes and a malum perforans on the right sole. He also had generalized arteriosclerosis as well as a polyneuropathy with a dry foot and typical foot deformation as well as decreased in sensitivity. Intensive local care for 35 days led to no improvement of the ulcerations. Then G-CSF (Neupogen) was administered in a total dose of 165 million IU over 11 days; the daily dose varied between 15-30 million IU depending on the absolute leucocyte count. In addition 500 mg of oral ciprofloxacin (Ciproxin) was given b.i.d. This treatment led to a significant improvement of the lesions. Within 11 days cost analysis suggests G-CSF may be a cost-effective addition to antimicrobial therapy in diabetic foot infection.
