This study assessed the impact of a randomized trial of nursing-based case management for patients with chronic obstructive pulmonary disease, their caregivers, and nursing and medical staff. Sixty-six patients were matched by FEV on admission to hospital, and randomized into an intervention or control group. Intervention group patients reported significantly less anxiety at 1 month postdischarge; however, this effect was not sustained. There was little difference between groups in terms of unplanned readmissions, depression, symptoms, support, and subjective well being. Interviews with patients and caregivers found that the case management improved access to resources and staff-patient communication. Interviews with nursing and medical staff found that case management improved communication between staff and enhanced patient care.(1)

The efficacy and toxicity of leucovorin 500 mg/m2 administered intravenously (IV) over 30 minutes daily for five days followed in one hour by fluorouracil (5-FU) 375 mg/m2 administered IV daily for five days, each given every 3 weeks, was assessed in 54 previously treated patients with metastatic breast cancer. An overall objective response rate of 24% was achieved (95% confidence interval, 13% to 38%), with an additional 56% of patients maintaining stable disease. Eleven of 12 patients who responded had received previous 5-FU therapy. Toxicity of this regimen included grade 3 diarrhea in 13%, grade 3 or 4 mucositis in 33%, grade 3 or 4 granulocytopenia in 65%, and grade 3 or 4 thrombocytopenia in 19%. Delay of treatment was required for hematologic toxicity in 44 patients. Thirty-eight patients required dose reductions due to toxicity. Biochemical evaluation of tumor biopsy specimens obtained from 17 patients used as their own controls with and without leucovorin was performed. These studies reveal an increased stabilization of the 5-fluorodeoxyuridylate (FdUMP)-thymidylate synthase (TS) folate ternary complex with the addition of leucovorin. There was a 71% +/- 14% occupancy or inhibition of the enzyme with the use of both 5-FU and leucovorin, v 30% +/- 13% for 5-FU alone (P2 less than .037). The percent TS bound in responding patients was substantially higher than in those patients with progressive disease. Finally, the mean total tumor TS pre-therapy in seven patients was 31 fmol/mg compared with a mean of 81 fmol/mg in these same seven patients 24 hours after therapy. This 2.6-fold increase suggests that there is an induction of the enzyme, TS, with 5-FU treatment.

A dose of CY at 2,000 mg/m2 can be administered every 2 weeks with DOX and G-CSF for eight cycles in the outpatient setting with manageable toxicity. The majority of women described levels of physical symptoms and emotional distress as tolerable during treatment.
