This clinical trial is focused on patients with certain types of cancer, specifically melanoma of the head, neck, or upper part of the trunk, oral cancer, and penile cancer. The study is investigating a new method for identifying sentinel nodes, which are the first lymph nodes to which cancer cells are likely to spread from a primary tumor. The treatment being studied involves a combination of two substances: Indocyanine Green and Technetium (99mTc) Nanocolloid. These substances are used together as a hybrid tracer to help locate sentinel nodes during a procedure called a sentinel node biopsy.
The purpose of the study is to validate the effectiveness of this hybrid tracer in accurately identifying sentinel nodes. The study will compare the results of using the hybrid tracer with the standard method, which uses only Technetium (99mTc) Nanocolloid. Participants will receive an injection of the tracer substances, and imaging techniques such as lymphoscintigraphy and SPECT/CT will be used to visualize the sentinel nodes before surgery. The study aims to ensure that the hybrid tracer can reliably identify the same number of sentinel nodes as the standard method.
Throughout the study, researchers will monitor the number and intensity of the nodes detected by both the hybrid tracer and the standard method. This will help determine if the new method is as effective as the current standard in identifying sentinel nodes. The study is expected to provide valuable information that could improve the accuracy of sentinel node biopsies in patients with these types of cancer.
