Home administration of bortezomib in multiple myeloma is cost-effective and is preferred by patients compared with hospital administration: results of a prospective single-center study.

BACKGROUND: Subcutaneous (s.c.) administration of bortezomib is the most widely used route of administration for the treatment of patients with multiple myeloma. No study has as yet prospectively evaluated home versus hospital administration of s.c. bortezomib with respect to patient preference and cost. PATIENTS AND METHODS: In this prospective trial, myeloma patients received the first administration of s.c. bortezomib of each cycle in the outpatient unit of the Department of Hematology. When possible, all subsequent doses of bortezomib within each cycle were provided at home. A cost analysis was carried out to compare the average cost of an injection of bortezomib in the outpatient unit and at home. In order to compare hospital and home administration of bortezomib for preference and satisfaction, patients had to complete 2 simple questionnaires analyzing 16 criteria, such as quality of life, well-being, social life, satisfaction, safety, quality of care, the reduction in personal transportation time, and personal anxiety. Each item was analyzed using a Likert scale. RESULTS: Fifty patients were studied. Overall, a total of 1043 s.c. injections of bortezomib were carried out, 655 (62.8%) at home, and 388 (35.2%) in the outpatient unit. The cost analysis showed that the total cost of one s.c. injection of bortezomib in the outpatient unit was €1510.09 versus €1224.57 for the home administration, which represents a reduction of €285.52, i.e. 20% of the cost of the hospital administration. The evaluation of patient preference and satisfaction showed that home administration improved the quality of life in 84% of the patients, increased well-being in 78%, and improved the activities of daily living in 72% of the cases. Overall, 98% of the patients noted their preference for home administration over the hospital administration of bortezomib. CONCLUSION: Home administration of s.c. bortezomib is cost-effective and is preferred by myeloma patients compared with hospital administration.

18F-FDG PET/CT for the assessment of gastrointestinal GVHD: results of a pilot study.

This prospective pilot study aimed to evaluate the predictive value of (18)F-FDG PET/CT for early diagnosis of acute gastrointestinal GVHD (GI-GVHD). In all, 42 consecutive patients who received allo-SCT were included. (18)F-FDG PET/CT was systematically performed at a median of 28 (range, 24-38) days after allo-SCT. (18)F-FDG PET/CT data review was positive in 15 cases (36%) (9 true positive (TP) cases and 6 false positive (FP) cases) and negative in 27 cases (64%; 26 true negative (TN) cases and 1 false negative (FN) case) at visual analysis. Sensitivity, specificity, positive predictive value, negative predictive value and accuracy of (18)F-FDG PET/CT for the diagnosis of acute GI-GVHD were, respectively, 81%, 90%, 60%, 96% and 83%. There were no significant differences of SUVmax values between grade 1-2 GI-GVHD and severe grade 3-4 GI-GVHD. Overall, these preliminary findings suggested that the inflammatory activity of the gastrointestinal tract associated with acute GI-GVHD could be assessed by (18)F-FDG PET/CT suggesting that noninvasive (18)F-FDG PET/CT could become a valuable examination to be performed shortly before endoscopy to map acute GI-GVHD lesions, guide the biopsy sites and choose the appropriate endoscopic procedure, especially in those asymptomatic patients with a positive (18)F-FDG PET/CT.
