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

February 18, 2025 updated by: Radboud University Medical Center

Injection of 99mTc-nanocolloid and ICG to Identify, Retrieve and Qualify Tumor Draining Lymph Nodes in Early-stage Lung Cancer

The patient wil receive intra- or peritumoral injections of 99mTc-nanocolloid if malignancy is found during a navigation bronchoscopy. A SPECT/CT-scan will be made to image injections sites and sentinel lymph nodes (SLN). If surgery takes place to treat the lung cancer, ICG will be injected and fluorescent lymph nodes will be extensively assessed by a pathologist.

Detailed Description

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.

What is the study measuring?

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Feasibility of SLN procedure
Time Frame: During the study intervention
This is a qualitative outcome measurement that will be assessed by the involved physicians based on the ability to inject 99mTc-nanocolloid and ICG, and the ability to detect the tumor draining lymph nodes based on their drainage patterns.
