Endobronchial Ultrasound-guided Intratumoral Injection of Cisplatin for the Treatment of Isolated Mediastinal Recurrence of Lung Cancer
Chapters
Summary February 12th, 2017
The management of isolated recurrent lung cancer in a previously-irradiated field is challenging. Here, we describe an endobronchial ultrasound (EBUS)-guided cisplatin injection for the management of patients with localized lung cancer recurrence in a previously-radiated field.
Transcript
The overall goal of this procedure is to describe an endobronchial ultrasound or EBUS-guided cisplatin injection for the management of patients with localized lung cancer recurrence in a previously radiated field. This method can help answer key questions in the field of lung cancer treatment about the safety and efficacy of EBUS-guided trans-bronchial intratumoral injection of cisplatin for recurrence of lung cancers in the post-radiated field. The main advantage of this technique is that it provides an alternative treatment option to systemic chemotherapy for patients with isolated, hilar, and mediastinal recurrence of lung cancer.
For real-time visualization of hilar, mediastinal, and peribronchial structures for intratumoral cisplatin injection, first intravenously administer dexamethasone and ondansetron to a patient who has abstained from oral food and fluids for at least six hours. Next, induce conscious sedation with intravenous Midazolam and Fentanyl treatment, coupled with the topical application of five milliliters of Lidocaine. Use standard monitoring, including a continuous 3-lead electrocardiogram for heart rate monitoring, continuous pulse oximetry, and respiratory rate measurements.
Now locate the target lesion using a convex probe EBUS with a built-in ultrasound probe on a flexible bronchoscope to advance the scope through the vocal cords. When the scope reaches the airways, turn on the EBUS processor and use one to two milliliters of normal saline to inflate the balloon at the tip of the scope. Flex the scope across the airway wall to locate the lesion.
Then deploy the 22-gauge EBUS needle through the working channel of the scope and lock the needle into position. Under real-time ultrasound guidance, puncture the tracheobronchial wall and insert the needle into the target lesion. Remove the stylet within the needle and inject 10 milliliters of cisplatin into the lesion.
Then retract the needle back into the sheath and inject the needle into a separate area of the lesion for the injection of another 10 milliliters of cisplatin. Remove the needle from the working channel of the scope and suction any additional drug from the distal airways. Then remove the bronchoscope.
In this representative study, 8 to 12 weeks after therapy, 69%of the patients were classified as responders and 31%as non-responders, with a median survival of 8 months, 10 months for the responders, and six months for the non-responders, with a significantly higher progression-free survival rate observed in the responders group. While attempting this procedure, it is important to select appropriate patients, and to perform all of the steps in the protocol in a systematic manner. After its development, this technique paved the way for us and other researchers in the field of lung cancer to explore intratumoral chemo and other immunotherapies in animal models and in humans.
After watching this video, you should have a good understanding of how to treat mediastinal and hilar recurrence of lung cancer with EBUS-guided intratumoral cisplatin injection.
