Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

This study evaluates the diagnostic accuracy of Indocyanine Green (ICG) fluorescence imaging in visualizing residual lesions of Giant Cell Tumor of Bone (GCTB) in the tumor cavity during surgery. Patients diagnosed with GCTB will receive an intravenous injection of ICG prior to the operation to label tumor tissues. During the procedure, surgeons will use a near-infrared fluorescence imaging system to visualize the tumor cavity and identify potential residual lesions after standard curettage. The study aims to determine the sensitivity, specificity, positive predictive value, and negative predictive value of ICG fluorescence imaging by comparing the intraoperative fluorescence findings with the final pathological results of the validation samples.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Giant Cell Tumor of Bone (GCTB) poses a significant surgical challenge due to the difficulty in detecting microscopic residual tumor tissues in the bone cavity, which contributes to a high local recurrence rate. This prospective, single-center, single-arm study aims to evaluate the accuracy of Indocyanine Green (ICG) fluorescence imaging in visualizing GCTB lesions during surgery. Eligible patients will receive an intravenous injection of ICG (0.25-0.5 mg/kg) 1-6 hours before surgery. Following standard tumor curettage under white light, the bone cavity will be systematically explored using a near-infrared fluorescence imaging system to visualize potential residual tumor tissues. The surgeon will obtain validation samples from fluorescence-positive areas, fluorescence-negative background tissues, and post-treatment beds for blinded pathological assessment. The study will quantify the diagnostic performance of ICG imaging by calculating sensitivity, specificity, positive predictive value, and negative predictive value based on the pathological gold standard, alongside secondary analyses of tumor-to-background ratios and microscopic tumor boundary concordance.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

ICG Fluorescence Imaging Group

All enrolled participants receive ICG fluorescence-guided surgery. Following standard tumor curettage, the bone cavity is systematically explored using a near-infrared fluorescence imaging system. The intervention consists of detecting residual fluorescence signals, obtaining verification samples for blinded pathological assessment, and performing supplementary curettage of confirmed suspicious lesions to achieve potentially cleaner surgical margins.

Group Type EXPERIMENTAL

Indocyanine Green

Intervention Type DRUG

Participants receive an intravenous injection of Indocyanine Green (ICG) at a dose of 0.25-0.5 mg/kg, 1-6 hours prior to surgery. Intraoperatively, a near-infrared fluorescence imaging system is used to guide the exploration of the bone cavity. The intervention involves a "verify first, treat later" protocol: it includes diagnostic verification sampling of fluorescence-positive areas and, crucially, therapeutic supplementary curettage of residual fluorescent lesions that were missed during standard white-light surgery.
