While rereading pathology reports is always good practice, it provides the most clinical value in cases of suspected ET. These patients are frequently reclassified as having prefibrotic myelofibrosis, a diagnosis that significantly alters patient counseling, prognosis, and long-term management strategies.

A blinded central radiology review is not the absolute gold standard for assessing patient progression. Expert clinicians argue their holistic assessment, incorporating the patient's clinical status and other biomarkers alongside scans, provides critical context that a disconnected reviewer lacks.
A key conceptual shift is viewing ctDNA not as a statistical risk marker, but as direct detection of molecular residual disease (MRD). This framing, similar to how a CT scan identifies metastases, explains its high positive predictive value and justifies its use in making critical treatment decisions.
Clinicians can reassure myelofibrosis patients that the drop in hemoglobin often seen when starting ruxolitinib does not carry the same negative prognostic weight as anemia caused by the disease itself. This distinction is crucial for managing patient expectations and continuing effective therapy despite initial side effects.
A diagnosis of myelofibrosis without a JAK2, CALR, or MPL mutation should be treated as a red flag, not a final diagnosis. It warrants a deeper investigation for alternative causes, such as MDS/MPN overlap syndromes or secondary fibrosis from other conditions like autoimmune disease or hairy cell leukemia.
For myelofibrosis patients with profound splenomegaly but only moderate thrombocytopenia (platelets 50k-100k), fedratinib may be the best frontline option. It is arguably the most potent JAK inhibitor for spleen reduction and is approved for use in patients with platelet counts as low as 50,000.
The modern practice of waiting for detailed diagnostic and genetic information before starting AML therapy provides a crucial, previously unavailable window of time for clinicians to conduct thorough fitness and geriatric assessments on their older patients.
In patients with systemic mastocytosis and an associated hematologic neoplasm (SM-AHN), the primary clinical challenge is determining which disease component is driving the main problems, such as cytopenias. This is critical because KIT inhibitors treat the SM, but the AHN may require a completely different therapy.
A key clinical nuance in CLL is that not all prognostic markers are static. The IGHV mutation status remains unchanged, requiring a one-time test. However, chromosomal abnormalities like deletion 17p can evolve, necessitating re-evaluation at each relapse to guide subsequent therapy choices and adapt the treatment strategy.
The NCI-supported MyeloMatch trial is pioneering a new standard for AML diagnostics, providing comprehensive genomic, FISH, and karyotype analysis within 72 hours. This rapid turnaround allows for immediate risk stratification and assignment to appropriate clinical trials.
TP53-mutated AML carries an extremely poor prognosis, significantly worse than other adverse-risk subtypes. When TP53 patients are excluded from analyses, the survival gap between the remaining adverse-risk and intermediate-risk patients narrows considerably, clarifying risk stratification.
