Abstract
MERONO SAURA, Ma Antonia et al. Analysis of the "Off label" drug use in hematology and oncology. rev.colomb.cancerol. [online]. 2020, vol.24, n.1, pp.3-10. Epub May 10, 2020. ISSN 0123-9015. https://doi.org/10.35509/01239015.32.
Background and objective:
the use of off-label drugs is the use of medications in conditions other than those included in its prescribing information. The objective of this paper is to analyze the off-label drugs applications and their results, performed by the Oncology and Hematology services in a second level hospital.
Materials and methods:
A retrospective observational study of all requests for "off label" drugs received by the Pharmacy Service is carried out. The drugs are classified according to economic impact, a classification according to the type of drug and the reason for the request and according to the degree of evidence. The demographic, diagnostic and treatment data of the patients are analyzed for each request. A follow-up of adverse effects, median progression-free survival and median overall survival is presented.
Results:
85 treatment requests are approved. Most of the treatments are high impact, mainly aimed at rare pathologies and last treatment options. 22% of the requests have a high degree of evidence. Progression free survival (PFS) and overall survival (OS) are 6.6 (95% CI 5.2-8) and 9.7 months (95% CI 8.2-11.2). 18.7% of patients have grade 3-4 toxicity when receiving treatment.
Conclusions:
Despite the heterogeneity of the pathologies, and the low evidence, the results obtained in SLP and SG, together with the low toxicity, force us to continue advancing in the evaluation of this type of treatments.
