Conditions

Early-stage Lung Cancer

Keywords

Sentinel Lymph Node procedure, 99mTc-nanocolloid, ICG, SPECT/CT-imaging

Brief summary

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.

Interventions

RADIATION99mTc-nanocolloid

Injection of 99mTc-nanocolloid when lung cancer is diagnosed during a navigation bronchoscopy, followed by one or two SPECT/CT-scans.

DRUGICG

If patient undergoes surgery to treat the lung cancer, ICG will be injected and retrieved fluorescent lymph nodes will undergo additional pathological assessment.

Design outcomes

Primary

MeasureTime frameDescription
Feasibility of SLN procedureDuring the study interventionThis 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.

Secondary

MeasureTime frame
Successfulness of injection method (intra- or peritumoral)During the first intervention
Number of SLN found by SPECT/CT-imagingOn the day of the first intervention
Number of SLN found by ICGOn the day of the second intervention
Number of metastasis found by additional pathologyUp to two weeks after the second intervention
