Follow-up

Further Outpatient Care

  • In patients with secondary thrombocytosis (reactive thrombocytosis) for whom the causal comorbid condition has not been identified, maintain complete careful outpatient monitoring with physical examination and routine laboratory tests to exclude the development of an occult disorder (eg, malignancy).

Prognosis

  • In general, secondary thrombocytosis (reactive thrombocytosis) is a temporary laboratory anomaly that resolves when the primary causative condition is addressed.
  • The overall prognosis of secondary thrombocytosis (reactive thrombocytosis) reflects that of the underlying associated condition.

Miscellaneous

Medicolegal Pitfalls

  • If no reason is identified for the secondary thrombocytosis (reactive thrombocytosis), patients require regular follow-up examinations to monitor platelet counts. The potential for occult malignant diseases in the appropriate clinical setting warrants attentive follow-up care. If the platelet counts continue to rise with no obvious explanation, suspect clonal thrombocytosis7,12 and consider platelet-reductive therapy.
