    Study PurposeMalignant central airway obstruction (CAO) in non-small cell lung cancer (NSCLC) is associated with high morbidity and requires endobronchial palliative treatment to re-establish a free air passage. We investigate intratumoral therapy combining anti-angiogenic and cytotoxic as a feasible therapeutic modality to treat malignant CAO.Study DesignTen NSCLC subjects with symptomatic malignant CAO underwent endobronchial intratumoral cisplatin and Endostar co-injection after tumour debulking next to systemic cisplatin-based chemotherapy. Injection was performed immediately after debulking surgery and was then carried out on day 2, day 6 and day 10 past systemic chemotherapy. Nine subjects of control group constantly received traditional cisplatin-based chemotherapy. Bronchoscopy, CT scanning, histology, FEV1/FVC ratio, Karnofsky performance (KPS) and shortness of breath scores were analysed to assess therapeutic efficacy.ResultsAll 10 subjects benefited from the intratumoral cisplatin and endostar co-injection and systemic chemotherapy combination therapy. Bronchoscopy and CT scanning analyses showed a massive airway widening after treatment. Increased KPS and reduced shortness of breath score were also observed. A substantial improvement of lung function was further confirmed by increased FEV1/FVC ratio. For subjects of control group, the improvement was moderate and obviously not as optimal as the 10 subjects with intratumoral injection.ConclusionsWe have shown that the intratumoral injection of cytotoxic cisplatin plus anti-angiogenic Endostar is an effective and safe adjuvant therapeutic option to treat malignant CAO in clinical practice. This time-staggered local and systemic treatment combination improves quality of life and clinical parameters, thus may provide a feasible therapeutic option for symptomatic CAO.© Author(s) (or their employer(s)) 2022.
