Clinical Scorecard: A novel label-free nanoplasmonic biosensor for distinguishing tumor margins during surgery for brain metastases

At a Glance

CategoryDetail
ConditionBrain metastases
Key MechanismsNanostructured plasmonic biosensors based on extraordinary optical transmission (EOT) detect biophysical differences in tissue.
Target PopulationAdults ≥ 18 years of age with newly diagnosed brain metastases without prior local treatment.
Care SettingSurgical treatment in a multicenter hospital setting.

Key Highlights

  • Brain metastases are the most common intracranial tumors in adults.
  • Microscopic infiltration complicates the achievement of gross total resection.
  • Current intraoperative tools for margin assessment lack biological specificity.
  • EOT-based biosensors can provide real-time characterization of tumor margins.
  • The study assesses the feasibility and diagnostic performance of the biosensor.

Guideline-Based Recommendations

Diagnosis

  • Histopathological confirmation of brain metastases is required.

Management

  • Surgical resection is a key treatment for selected patients.

Monitoring & Follow-up

  • Intraoperative assessment of tumor margins is essential.

Risks

  • Inadequate margin assessment may lead to incomplete resection and neurological morbidity.

Patient & Prescribing Data

Patients with brain metastases candidates for surgical treatment.

Standard clinical protocols guide patient selection for surgery.

Clinical Best Practices

  • Utilize standardized intraoperative tissue-sampling protocols.
  • Incorporate advanced imaging techniques for preoperative planning.
  • Ensure ethical standards are met in research involving human subjects.
