BACKGROUND AND OBJECTIVE: Little is known about malignant central airway obstruction (MCAO) complicating the metastatic spread of non-bronchogenic solid cancers (NBC) and their bronchoscopic management. This study aimed to describe the epidemiology of this population and determine prognostic factors before therapeutic bronchoscopy (TB).
METHODS: In this multicenter study using the EpiGETIF registry, we analysed patients treated with TB for MCAO caused by NBC between January 2019 and December 2022.
RESULTS: From a database of 2389 patients, 436 patients (18%) with MCAO and NBC were identified. After excluding patients with direct local invasion, 214 patients (8.9%) were analysed. The main primaries involved were kidney (17.8%), colon (16.4%), sarcoma (15.4%), thyroid (8.9%) and head and neck (7.9%) cancers. Most patients (63.8%) had already received one or more lines of systemic treatment. Obstructions were purely intrinsic in 58.2%, extrinsic in 11.1% and mixed in 30.8%. Mechanical debulking was used in 73.4% of cases, combined with thermal techniques in 25.6% of cases. Airway stenting was required in 38.4% of patients. Median survival after TB was 11.2 months, influenced by histology (p = 0.002), performance status (p = 0.019), initial hypoxia (HR 1.45 [1.01-2.18]), prior oncologic treatment received (HR 1.82 [1.28-2.56], p < 0.001) and assessment of success at the end of the procedure (HR 0.66 [0.44-0.99], p < 0.001). Complications rate was 8.8%, mostly mild, with no procedure-related mortality.
CONCLUSION: TB for MCAO caused by a NBC metastasis provides rapid improvement of symptoms and prolonged survival. Patients should be promptly referred by medical oncologists for bronchoscopic management based on the prognostic factors identified.
