Multiple studies have demonstrated feasibility and safety of delivering cisplatin directly into lung tumors using endobronchial ultrasound guided-transbronchial needle injection (EBUS-TBNI). This technique relies on the use of a bronchoscope with an integrated ultrasound transducer allowing real-time visualization of, and delivery of cisplatin into, tumors lying in proximity to the central airways. Prior work has utilized this technique to treat loco regional recurrence in a previously radiated field. The goal of the current study is to identify the initial dose for intratumoral cisplatin.
The goal of the study is to identify the maximum tolerated dose of endobronchial ultrasound-guided transbronchial injection (EBUS-TBNI) of cisplatin for Stage IV lung cancer.
