a This entity includes two breast cancers, two colon cancers, and one cervical cancer. b Benign etiology consists of two cryptococcal infections, one pneumonia, and one necrotizing granuloma. c Patients with Stage IV include 1 stage IVa with only pleural metastasis from lung adenocarcinoma. Oligometastases were excluded here.
