Limb-sparing surgery for sciatic nerve tumors offers an alternative to amputation. Complete sciatic nerve resection in these cases can achieve acceptable functional outcomes, despite some mobility limitations.

Area of Science:

  • Orthopedic Oncology
  • Surgical Oncology
  • Neurosurgery

Background:

  • Malignancies involving the sciatic nerve typically necessitate amputation due to neurologic loss.
  • Limb-sparing surgery is an alternative approach for managing these complex tumors.

Purpose of the Study:

  • To evaluate the outcomes of limb-sparing surgery involving complete sciatic nerve resection for soft tissue malignancies.
  • To compare limb salvage with amputation for sciatic nerve tumors.

Main Methods:

  • Retrospective review of 20 patients with sciatic nerve tumors (neurofibrosarcomas, liposarcomas, etc.) treated with limb-sparing surgery and complete sciatic nerve resection.
  • Analysis of patient demographics, tumor characteristics, treatment modalities (radiotherapy), and functional outcomes (Toronto Extremity Salvage Score).

Main Results:

  • 14 out of 20 patients survived at a mean follow-up of 35 months.
  • Local recurrence rate was 10%, with distant metastases in 12 patients.
  • The average Toronto Extremity Salvage Score was 74%, with most patients experiencing mild to moderate disability but maintaining indoor ambulation.

Conclusions:

  • Limb-sparing surgery with complete sciatic nerve resection is a viable alternative to hip disarticulation or hindquarter amputation for sciatic nerve tumors.
  • This approach can provide acceptable functional outcomes for patients with these challenging malignancies.
