OBJECTIVES: In patients with testicular Germ Cell Tumors (GCT) noncaseating granulomatous diseases such as Sarcoid Like Lesions (SLL) or Sarcoidosis can mimic metastasis due to hilar or mediastinal lymphadenopathy. Due to the clinical and prognostic impact, exclusion of malignant diseases is mandatory.
MATERIAL AND METHODS: Retrospectively, data from 636 GCT patients, who were seen in the course of tumor surveillance/follow-up were collected. Focus was put on the detection of tumor relapse vs. noncaseating granulomatous reactions. For the differential diagnosis of thoracic lymphadenopathy or pulmonary infiltrates either bronchoscopy (e.g., endobronchial ultrasound-guided transbronchial needle aspiration, endobronchial ultrasound-guided transbronchial needle aspiration) or thoracic surgery was performed. Both GCT patients with either tumor relapse or coexisting SLL were compared to GCT patients without SLL and tumor relapse.
RESULTS: Twenty-nine patients suffered from suspected tumor relapse. Whereas thoracic relapses were suspected in 15 patients on chest computed tomography, thoracic relapse was confirmed in 5 cases by open surgery. In 2 cases open surgery yielded reactive lymphadenitis, and in 8 cases SLL was diagnosed either via EBUS-TBNA (n = 7) or thoracoscopic wedge resection plus lymphadenectomy (n = 1). With focus on overall survival, no relevant difference was found between all tested subgroups (P = 0.265; logrank test).
CONCLUSIONS: In GCT patients, the coexistence of noncaseating granulomatous disease is common. Minimal invasive bronchoscopic techniques can serve for the cytopathologic exclusion of malignant thoracic manifestations. In our monocenter patient group the coexistence of SLL did not have any prognostic impact on overall survival.
