Area of Science:

  • Oncology
  • Biomedical Engineering
  • Surgical Oncology

Background:

  • Electrochemotherapy (ECT) is an effective treatment for surface skin cancers.
  • Its application for musculoskeletal tumors, including chondrosarcoma, remains largely unexplored.
  • Developing limb-preserving strategies for extremity sarcomas is crucial.

Purpose of the Study:

  • To evaluate the efficacy and safety of electrochemotherapy (ECT) for treating digital chondrosarcoma.
  • To assess ECT as a limb-preserving treatment modality for extremity sarcomas.

Main Methods:

  • A clinical trial was conducted on a 74-year-old female patient with digital chondrosarcoma.
  • The treatment involved intratumoral and intraarterial bleomycin sulfate administration followed by localized pulsating electrical stimuli.

  • Post-treatment biopsy, marginal tumor resection, and autologous bone grafting were performed.

    • Main Results:

    • Electrochemotherapy resulted in 90% tumor necrosis.
    • The patient remained disease-free for 3 years post-treatment.
    • Amputation of the affected finger was successfully avoided.

    Conclusions:

    • Electrochemotherapy demonstrates potential as a viable limb-preserving treatment for digital chondrosarcoma.
    • ECT may offer an effective alternative to amputation for extremity sarcomas.
    • Further clinical trials are warranted to confirm these preliminary findings.
