Fluorescent Intra-operative Tumor Margin Examination

Evaluation of Intraoperative Tumor Margin Identification With Fluorescent Dye Imaging

Source: ClinicalTrials.gov · Last updated 20 Feb 2026

Brief summary (registry, in English)

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.

Who cannot take part

Copied verbatim from ClinicalTrials.gov and grouped by topic. Only the trial team decides who can take part.

Prior treatment

  • Dialysis, renal failure, uremia

Age

  • Patients below the age of 18

Other

  • Pregnancy, breast feeding
  • Non- or minimally-recurrent masses (i.e. osteochondroma)

Who the study is looking for

  • 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.
