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 in patients with secondary thrombocytosis reflects that of the underlying associated condition. With certain disorders, however (eg, chronic obstructive pulmonary disease [COPD], [20] ovarian cancer [21] ), the presence of thrombocytosis indicates a worse prognosis than for patients with the disorder who do not have thrombocytosis. For example, Harrison et al reported that thrombocytosis was an independent risk factor for increased 1-year mortality after COPD exacerbations; however, patients with thrombocytosis who received antiplatelet therapy had significantly lower 1-year mortality.
