Study summary

The purpose of this research study is to look at how using an injectable marker called TraceIT can help with the radiation treatment planning process. TraceIT is a gel that dissolves in the body over time and can be injected and is visible on many types of images that can be used in the treatment planning process. If the exact edges of negative tumor margins can be marked before treatment planning, it is thought that the area receiving radiation can be more personalized, thus potentially reducing unnecessary radiation to areas that are cancer-free.

  • At least 18 years of age.
  • Ability to understand and willingness to sign an IRB approved written informed consent document.

Exclusion criteria

Exclusion Criteria:

    TraceIT Tissue Marker

    * Following successful tumor resection, TraceIT Tissue Marker will be applied in 0.2 to 0.5 mL injections at 5 locations to mark the tumor bed: superiorly, inferiorly, laterally, medially, and center of resection. The marginal injections will be within 3 mm of the resection edge and within 5 mm deep. The center of the resection bed will be injected within 5 mm deep if possible. * Within 6 weeks after surgery, a CT simulation scan will be performed per normal protocol for patients receiving surgery followed by adjuvant therapy. This scan will be used to generate the intensity-modulated radiation therapy (IMRT) treatment plan * Two treatment plans will be performed per patient using the simulation CT scan. One will be the standard of care treatment plan and will be the basis of the actual radiation treatment they receive. The second treatment plan will be based on utilizing the TraceIT hydrogel markers as a guide for the resection bed.

What researchers measure

Primary outcomes

  1. Percent Change in Total Mean Clinical Target Volumes (CTV) Between the Standard of Care Treatment Plan and the Treatment Plan Based on the TraceIT Hydrogel Markers

    -The mean total dose of each targeted site was totaled from the standard of care treatment plan and the TraceIT tissue marker treatment plan. The percent change in CTV was measured by standard field in cGy minus marker based in cGy = percent change in CTV (in cGy). The sites included left \& right submandibular, left \& right parotid, left \& right pharynx constrictor, oral cavity, lips, larynx, and spinal cord.

    Time frame: At the treatment planning (2-5 weeks after TraceIT hydrogel placement)

Secondary outcomes

  1. Percentage of Participants Experiencing an Adverse Event Related to TraceIT Injection

    Time frame: From time of injection through surgery (day 1)

  2. Anatomic Localization Related to Standard Treatment Fields Based on Anatomy as Measured by Number of Participants That Had Markers Visible

    Time frame: At the treatment planning (2-5 weeks after TraceIT hydrogel placement)

Outcome measures

PrimaryPercent Change in Total Mean Clinical Target Volumes (CTV) Between the Standard of Care Treatment Plan and the Treatment Plan Based on the TraceIT Hydrogel Markers

-The mean total dose of each targeted site was totaled from the standard of care treatment plan and the TraceIT tissue marker treatment plan. The percent change in CTV was measured by standard field in cGy minus marker based in cGy = percent change in CTV (in cGy). The sites included left \& right submandibular, left \& right parotid, left \& right pharynx constrictor, oral cavity, lips, larynx, and spinal cord.
