title: Discriminant analysis of prognostic factors for malignant fibrous histiocytoma in soft tissue.
abstract: We prospectively followed 32 patients with soft-tissue malignant fibrous histiocytoma (MFH). Parameters were age; sex; tumor size, location, and depth; operative method; chemotherapy; radiotherapy; and histology. Patients with recurrence or metastases due to MFH within 6 months after the initial operation were separated from those without these characteristics by discriminant analysis with statistically significant difference. The order of influential functions was histology, depth of tumor, operative method, and sex. Male patients with deep-seated storiform-pleomorphic type MFH, receiving less comprehensive surgery, had the greatest risk of local recurrence or early metastases. We have to pay particular attention to patients with these factors and perform adequate surgery, because local recurrence and metastases were found to be closely related, and to have a great influence on the prognosis of this disease. Discriminant analysis to separate patients with MFH recurrence or metastases within 6 months after the initial operation from those without these characteristics is worthwhile for prognostic assessment.
