Undifferentiated pleomorphic sarcoma/NOS (former pleomorphic and storiform MFH) of the extremities is a common malignant soft tissue tumor in adults. The objective of this study is to determine prognostic factors for the outcome after surgical treatment with respect to the recent developments in classification. From 1996 to 2004, 140 undifferentiated pleomorphic sarcomas/NOS were identified out of 1200 soft tissue sarcomas of the extremities that were treated at our institution and recorded in a prospective database. Overall survival (OS) and isolated local recurrence (ILR) were determined by Kaplan-Meier analysis. All tumors were retrospectively analyzed regarding prognostic factors of the disease, including patient’s background (primary or recurrent), histological grade (G2/G3), adjuvant chemotherapy and radiotherapy, size (T1-2) and depth of the tumor, and surgical margins (R0, R1, R2).

In 123 patients, a wide resection was performed (limb sparing surgery). In 9 patients, an amputation was necessary. The overall 5-year survival rate was 72% (median follow-up: 52 months). There was a significant difference between the group presenting with primary tumors (5y survival: 84%, p< 0.05) and recurrent tumors (5y survival: 62%, p< 0.05). Isolated local recurrence occurred in 36 patients.

In terms of OS and ILR, primary or recurrence, negative surgical margins, size and grading had a highly significant influence, whereas the site of surgery and adjuvant chemotherapy, adjuvant radiation and tumor depth did not. Prognosis for patients with undifferentiated pleomorphic sarcoma of the extremities depends predominantly on adequate wide resection of the primary tumor.

Reimplantation is a well-established procedure in reconstructive surgery. This is especially so after amputation of the upper limb since prostheses provide limited function. In unilateral amputation of the lower leg orthotopic reimplantation is the treatment of choice. With bilateral amputation, in which orthotopic reimplantation is not possible because of the complexity of the trauma, heterotopic reimplantation is an option.

We report five patients who received orthotopic and two who received heterotopic reimplantations of the lower leg. We assessed the functional outcome with reference to cutaneous sensation, mobility, pain, and the cosmetic result.

The functional outcome was good, as was the patients’ satisfaction. Their mobility, stability, and psychological state were satisfactory. Patients with heterotopic reimplantations preferred the reimplanted leg to a prosthesis. Although reimplantation of the lower leg requires prolonged hospitalisation, delayed mobilisation and secondary operations, we conclude that there is an indication for this operation in order to improve the patient’s quality of life.
