Experiencia del uso fuera de indicación de Eltrombopag en el tratamiento de la trombocitopenia asociada a tumores sólidos

Purpose: To describe the results of the off-label use of eltrombopag in patients with solid tumors and thrombocytopenia that limits chemotherapy. Methods: Retrospective observational study including all patients with solid tumors who were treated with eltrombopag for thrombocytopenia during the chemotherapy treatment between January 2012 and December 2014. Results: Six patients, with solid tumors and thrombocytopenia that limits chemotherapy treatment, received eltrombopag during the study and it was observed a decrease in the delay of chemotherapy cycles (4.83 ± 4.79 delayed cycles before starting eltrombopag vs 2.50 ± 4.32 delayed cycles during the treatment with eltrombopag, p=0.492) and an increase in the percentage of administrated dosage (89.29 ± 13.36% vs 91.43 ± 10.69%, p=0.682). Also, there was an increase in platelet nadir (55.29 ± 16.45x109/L vs 76.14 ± 36.38x109/L, p=0.248) without platelet transfusion support in any patient during treatment with eltrombopag. Conclusions: eltrombopag has resulted to be an alternative in the treatment of patients with thrombocytopenia that limits chemotherapy, clinical trials with more number or patients are needed to confirm these results.
