Sufferers with important thrombocythemia confronted a mean delay of 26.5 months between their first excessive platelet rely and analysis.
Sufferers skilled a big delay in receiving a necessary thrombocythemia (ET) analysis, with the typical time from the primary noticed elevated platelet rely to analysis spanning over two years (26.5 months), suggesting that the burden of ET could also be underestimated and highlights the necessity for better consciousness amongst healthcare suppliers, in keeping with a poster introduced the European Hematology Affiliation 2025 Congress.
The research discovered distinct tendencies amongst sufferers with elevated platelet counts. On common, platelet ranges had been 678 x 10⁹/L close to the index date. At the moment, 50.5% of sufferers had counts of 600 x 10⁹/L or greater, and 10.5% had ranges of 1,000 x 10⁹/L or greater. On the first signal of elevated platelets, the typical rely was 603.9 x 10⁹/L, with 31.1% of sufferers reaching 600 x 10⁹/L or extra and 4.6% reaching 1,000 x 10⁹/L or extra.
Total, 4.4% of sufferers had a historical past of splenomegaly. Almost half (49.3% of sufferers) had one other medical situation, mostly hypertension (49.3%), excessive ldl cholesterol (36.5%) or diabetes (15.6%). Coronary artery illness was seen in 9.3% of sufferers, and peripheral artery illness in 3%. As well as, 19.4% had a historical past of blood clots, most frequently deep vein thrombosis (7.2%), pulmonary embolism (4.5%), coronary heart assault (3.9%) or stroke (3.8%).
Among the many 1,350 sufferers studied, the median age on the index date was 64 years. Most sufferers (69.5%) had been feminine, and 83.3% recognized as White.
Examine Design
This research reviewed medical data from adults identified with ET between January 1, 2012, and September 5, 2024, throughout eight hospitals inside the Massachusetts Common Brigham well being system. To be included within the evaluation, sufferers wanted to have an official analysis of ET recorded throughout a medical go to, a second go to confirming the analysis by a specialist, and a excessive platelet rely — 450×10⁹/L or greater — inside the three months earlier than their analysis.
Researchers centered on every affected person’s well being care exercise throughout the interval main as much as their analysis. This included data resembling age, different well being circumstances, historical past of blood clots, lab outcomes and the period of time between the primary excessive platelet rely and the official analysis. The research additionally tracked how typically sufferers used well being care companies like outpatient visits, hospital stays and emergency room visits throughout this pre-diagnosis interval.
To higher perceive patterns of care, researchers in contrast well being care use earlier than and after the primary signal of elevated platelets. This strategy might assist determine methods to enhance how and when sufferers with ET are identified and managed, in keeping with the poster.
As a result of this research used information from tutorial hospitals in a single well being system, outcomes might not mirror the experiences of sufferers handled at group facilities. Some early medical historical past, together with the primary indicators of elevated platelets, might have occurred exterior the system and weren’t captured. Diagnoses and lab values had been based mostly on medical document codes, which might be incomplete or misclassified. The explanations behind sufferers’ well being care visits earlier than analysis weren’t included on this evaluation however could also be explored in future research.
ET is a uncommon, power blood most cancers marked by persistently excessive platelet counts, elevated danger of blood clots, and the potential to progress into extra critical circumstances like myelofibrosis or acute leukemia, the investigators famous.
Though blood clots might happen earlier than analysis, elevated platelet ranges are sometimes missed, particularly in sufferers with out signs. These challenges, together with low illness consciousness, can delay analysis. There’s restricted real-world analysis on how lengthy it takes to diagnose ET and the doable issues linked to these delays.
