Injection of 99mTc-nanocolloid and ICG to Identify, Retrieve and Qualify TDLN in Early-stage NSCLC

When malignancy is found during navigation bronchoscopy, study participants will receive intra- or peritumoral injections of 99mTc-nanocolloid. Following, up to 2 SPECT/CT-scans will be made to assess drainage of the injected tracer to the lymph nodes. If patients undergo resection of the lung lesion, ICG will be injected. The involved lung tissue will be removed, followed by routine complete lymph node dissection. The fluorescent lymph nodes will be more extensively evaluated by the pathologist.
