Abstract:
A surgical technique for removal of the adductor muscle group invaded by primary soft tissue sarcoma is described. A review of the clinical histories of 14 patients showed that the major complication of this procedure was prolonged suction catheter drainage of lymph, followed by sepsis along the drain tracts. No rationale for removal of the inguinal lymphatics in the absence of direct involvement by tumor or palpable lymphatic metastasis was found in the literature. We conclude that in primary soft tissue sarcoma of the adductor muscle group, clinically uninvolved superficial inguinal lymphatics should be carefully preserved. The limited benefits from removal of these lymph nodes does not merit the marked increase in operative morbidity. A surgical technique for adductor muscle group excision is presented that allows the best principles of sarcoma surgery to be practiced and that carries on acceptable operative morbidity rate.
Insights
For primary soft tissue sarcoma of the adductor muscle group, preserving clinically uninvolved superficial inguinal lymphatics is recommended. Routine removal of these lymph nodes increases operative morbidity without clear oncologic benefit.
Area of Science:
- Oncology
- Surgical Oncology
- Orthopedic Oncology
Background:
- Primary soft tissue sarcoma can invade the adductor muscle group, necessitating surgical excision.
- Standard surgical approaches may involve removal of inguinal lymphatics, but the rationale for this is not always clear.
Observation:
- A review of 14 patients undergoing adductor muscle group sarcoma excision revealed significant complications.
- Prolonged lymph drainage via suction catheter and subsequent sepsis along drain tracts were major issues.
Findings:
- No literature supports routine removal of inguinal lymphatics when not directly involved by tumor or palpable metastasis.
- Preserving clinically uninvolved superficial inguinal lymphatics is advised for adductor muscle group sarcoma.
- The oncologic benefits of prophylactic lymph node removal do not outweigh the increased operative morbidity.
Implications:
- Surgical techniques for adductor muscle group sarcoma should prioritize preserving uninvolved lymphatics.
- This approach aims to reduce postoperative complications such as lymphorrhea and sepsis.
- Adherence to oncologic principles with modified lymphatic management can achieve acceptable morbidity rates.
