Original description
Tumor margin confirmation is important to confirming appropriate disease excision. Current standard of care is to take select margin samples to pathology for intra-operative readings. However, this is expensive, time consuming, and only assesses the margin contained within the specific sample. In prior work the investigators have determined that indocyanine green (ICG) is highly specific to the tumor bed when injected shortly before surgery. The investigators hypothesize that ICG will be able to accurately identify residual positive tumor margins during sarcoma excision procedures.Read full original descriptionShow less

Evaluation of Intraoperative Tumor Margin Identification With Fluorescent Dye Imaging

Tumor margin confirmation is important to confirming appropriate disease excision. Current standard of care is to take select margin samples to pathology for intra-operative readings. However, this is expensive, time consuming, and only assesses the margin contained within the specific sample. In prior work the investigators have determined that indocyanine green (ICG) is highly specific to the tumor bed when injected shortly before surgery. The investigators hypothesize that ICG will be able to accurately identify residual positive tumor margins during sarcoma excision procedures.

Inclusion: Patients above the age of 18 with a primary musculoskeletal tumor that has been indicated for surgical excision by a fellowship trained orthopaedic oncologist; Surgical consent was obtained prior to research consent; Patients with a biopsy-confirmed primary soft tissue or bone tumor that has not been previously excised and has a known risk of local or remote recurrence.

Exclusion: Prior surgery local to the mass being excised; Patients with a history of anaphylactic reaction to contrast media or fluorescein allergy; Dialysis, renal failure, uremia; Patients below the age of 18; Pregnancy, breast feeding; Non- or minimally-recurrent masses (i.e. osteochondroma).
