Diagnosing ABPA in cancer patients can be challenging due to overlapping symptoms. A combination of clinical, radiological, and immunological criteria is used. This includes:
Elevated serum IgE levels Positive skin test or specific IgE for Aspergillus Radiographic evidence of bronchiectasis or infiltrates Sputum culture positive for Aspergillus
In cancer patients, additional diagnostic caution is required to rule out other potential causes of symptoms, such as metastasis or drug reactions.
