Neurofibrosarcomas of the upper extremity

Area of Science:

• Oncology
• Surgical Pathology
• Genetics

Background:

• Neurofibrosarcoma is a rare malignancy arising from nerve sheath cells.
• Patients with von Recklinghausen's disease have an increased risk of developing neurofibrosarcoma.
• Malignant tumors of the hand and upper extremity are uncommon, posing diagnostic and therapeutic challenges.

Purpose of the Study:

• To review cases of neurofibrosarcoma involving the upper extremity.
• To analyze clinical presentation, treatment, and outcomes for this rare cancer.
• To identify prognostic factors for neurofibrosarcoma of the upper extremity.

Main Methods:

• Retrospective review of biopsy-proven neurofibrosarcoma cases.
• Data collection from 1950 to 1987 at the University of Michigan.
• Analysis of patient demographics, clinical history, treatment modalities, and survival data.

Main Results:

• Six cases of upper extremity neurofibrosarcoma were identified in patients with von Recklinghausen's disease.
• Average age at presentation was 37 years, with a median age range of 15 to 63 years.
• Five out of six patients died of metastatic disease within an average of 3 years; one patient survived 18 years post-amputation despite recurrence.

Conclusions:

• Neurofibrosarcoma of the upper extremity is a highly lethal cancer with a poor prognosis.
• Early diagnosis and aggressive surgical management, including amputation, offer the best chance for long-term survival.
• Close monitoring and prompt treatment are essential for patients with von Recklinghausen's disease and suspected neurofibrosarcoma.
