Results of treatment of malignant soft tissue tumours in the groin

Abstract

Soft tissue sarcomas of the inguinal region are a challenge with regard to achieving clear margins, reconstruction of the femoral vessels, and soft tissue coverage. Six men aged 39 to 48 years and one woman of 56 were treated for soft tissue sarcomas of the groin. All patients were treated with local en bloc resections including the femoral artery, vein, and nerve. In two patients the soft tissue defect was covered primarily with an ipsilateral rectus abdominis muscle flap, in two others (because of wound dehiscence) coverage was achieved with the opposite rectus abdominis muscle pedicle flap as we were afraid of closure of the ipsilateral deep epigastric vessels. In the others local measures were sufficient, however, wound healing was usually delayed. Histopathological examination showed tumour-free margins in each case. One patient developed a local recurrence, but had had no radiotherapy because of problems with wound healing. A high rate of local tumour control in soft tissue sarcomas of the inguinal region can be achieved with the combination of surgical resection and radiotherapy. No compromise should be made with aggressive soft tissue coverage to protect the vascular reconstruction, control wound healing after neoadjuvant radiotherapy, or allow immediate adjuvant radiotherapy. At primary wound closure we would generally use an ipsilaterally distally pedicled rectus abdominis muscle flap if the deep epigastric vessels can be preserved or – if the ipsilateral vessels need be resected to achieve clearance of tumour - use a contralateral flap.
