Baseline blood counts/spleen size/BM/molecular testing
PPV-MF, Splenomegaly
Baseline blood counts can be found in Table Splenomegaly was reported by physicians in 83% of patients; however, spleen palpation at baseline was only documented in 62.7% of patients. Median spleen length at baseline was 13.9 cm below the costal margin (BCM), with a median size of 17 cm BCM for PPV-MF patients. Median spleen length by computerized tomography (CT) or magnetic resonance imaging (MRI) scan was 19.5 cm.In 87.5% (At study entry of patients, physicians were asked if they had performed a molecular analysis of the patients before study start. A molecular analysis, which was not mandatory, was done in 83% (As stated above, the study protocol did not provide mandatory examinations, so this may reflect the real-world behavior of German physicians treating MF patients. Only 151 (32.5%) patients had at least one molecular examination performed as a possible examination in the study (up to three in some patients), and results were reported from 140 patients (30.2%), with 110 of these patients harboring the
