Validation of a new hybrid tracer for sentinel node biopsy in cancer patients

Validation of ICG-99mTc-nanoscan as Hybrid Tracer for Sentinel Node Biopsy

Not applicable Interventional The Netherlands Cancer Institute · NCT06666634

This study is testing a new hybrid tracer to see if it works as well as the current one for helping doctors find cancerous lymph nodes in patients with penile cancer, melanoma, and oral cancer during surgery.

What this trial studies

This study aims to validate the use of ICG-99mTc-nanoscan as a hybrid tracer for sentinel node biopsy in patients with penile cancer, melanoma, and oral cancer. The investigators will compare the lymphatic drainage patterns and intraoperative signal intensities of ICG-99mTc-nanoscan with the established 99mTc-nanoscan. By ensuring that the new tracer maintains the same level of care as its predecessor, the study seeks to confirm its effectiveness in clinical settings. The trial will involve patients scheduled for sentinel node procedures as part of their routine care.

Who should consider this trial

Good fit: Ideal candidates include adults over 18 with clinical N0 stage penile cancer, melanoma, or oral cavity malignancies scheduled for sentinel node biopsy.

Not a fit: Patients with known allergies to the study materials, pregnant or breastfeeding women, and those with certain medical conditions like kidney insufficiency will not benefit from this study.

Why it matters

Potential benefit: If successful, this study could enhance the accuracy and effectiveness of sentinel node biopsies, leading to better surgical outcomes for cancer patients.

How similar studies have performed: Previous studies have successfully validated similar hybrid tracers, indicating a promising approach for this new validation.
