Efficacy and Safety of Ruxolitinib in Patients With Myelofibrosis

Efficacy and Safety of Ruxolitinib in Patients With Myelofibrosis: A Retrospective Multicenter Study

Ruxolitinib is a Janus kinase (JAK) 1/2 inhibitor currently used in the treatment of Myelofibrosis (MF). Ruxolitinib confirmed improvements in splenomegaly, MF-related symptoms and survival benefit in COMFORT and JUMP studies. At present, the real-world data on the efficacy and safety of ruxolitinib in the treatment of MF in China is still insufficient. The aim of this study was to evaluate the efficacy and safety of ruxolitinib in patients with MF and to provide guidance for the usage of ruxolitinib in MF in China.This was a retrospective, multicenter study of MF patients who received ruxolitinib treatment in Shandong province from August 2012 to December 2021. Data were analyzed using SPSS. Overall survival (OS) and Event-free survival (EFS) were estimated using the Kaplan- Meier method.

Inclusion Criteria:

1. Male or female patients aged ≥18 years with a diagnosis of primary or secondary MF by World Health Organization and International Working Group for Myeloproliferative Neoplasms Research and Treat- ment (IWG-MRT) criteria;
2. Received ruxolitinib treatment for ≥3 months.

Exclusion Criteria:

1. Malignant tumors with other progression or myelofibrosis secondary to other diseases;
2. Exclude myelofibrosis patients after splenectomy;
3. Patients with poor compliance with case follow-up or lost to follow-up.
