Malignant fibrous histiocytoma: Outcome of tumours in the head and neck compared with those in the trunk and extremities
ABSTRACT Malignant fibrous histiocytoma is one of the commonest soft tissue sarcomas in adults, affecting, in order of frequency, the extremities, trunk and head and neck. We treated 131 patients with malignant fibrous histiocytoma by radical, wide, or marginal resection. Their mean age was 43 years, and there were 54 in the head and neck and 77 in the trunk and extremities. The extent of clearance of the tumour, local recurrence, and 5-year survival were studied in these two groups. In the head and neck group, local recurrences developed in 86% after marginal resection, 66% after wide resection and 27% after radical resection. The comparative figures in the trunk and extremities group were 75, 71 and 18%, respectively. The overall 5-year survival was 48% in the head and neck group and 77% in the trunk and extremities group (p=0.03). Repeat operations for recurrences of tumour offered a 'cure rate' of 23% in the head and neck group and 61% in the trunk and extremities group. Inadequate resection of the sarcoma in the head and neck was associated with a high incidence of local recurrence and a poor prognosis. Therefore, we suggest that the initial operation for sarcoma in the head and neck should be as radical as possible to reduce the chance of local recurrence and to improve the outcome.

ABSTRACT: Malignant fibrous histiocytoma (MFH) is a rare neoplasm exhibiting a propensity for aggressive clinical behavior. Effective treatment modality is surgical resection with wide margins, but its rate of recurrence and metastasis is still high. Early detection and complete excision of the tumor is necessary. A MFH of the occipital developed in a 51-year-old woman eight years after surgery and radiation for medulloblastoma of the cerebellar vermis. The secondary neoplasm arose at the site of tumor resection within the irradiated field, and was resected. The development of sarcomas is a recognized complication of radiation therapy. The final diagnosis after the operation was MFH. Radiation-induced sarcoma (RIS) is well known, but radiation-induced MFH is relatively rare in the head and neck region, especially in the occipital. The imaging findings are not diagnosis specific, but strict follow-up within the radiation field by computerized tomography (CT) and magnetic resonance imaging (MRI) and appreciation of the expected latency period may help in providing the diagnosis of RIS.World Journal of Surgical Oncology 04/2014; 12(1):98.

ABSTRACT: Objective. To summarize the epidemiology of sarcomas occurring in the head and neck and identify prognostic factors for patient survival. Study Design and Setting. Cross-sectional analysis of the National Cancer Institute's Surveillance, Epidemiology and End Results (SEER) program. Methods. The SEER 18 registries, comprising sarcoma diagnoses made from 1973 to 2010, were queried for sarcomas arising in the head and neck. Pediatric and adult patients were analyzed separately, and multivariate and propensity-matched analyses were performed to identify predictors of disease-specific survival. Results. In all, 11,481 adult cases and 1244 pediatric cases were identified. In adults, the most common histologic subtypes were malignant fibrous histiocytoma (MFH), Kaposi sarcoma, and hemangiosarcoma, while in the pediatric cohort, the most common histologic subtypes were rhabdomyosarcoma, MFH, and osteosarcoma. Cause-specific 2-, 5-, and 10-year survival rates were 76%, 66%, and 61% for adults and 84%, 73%, and 71% for pediatric patients. Multivariate analysis performed for adults revealed that male gender, absence of radiation therapy, and stage I disease were associated with improved cause-specific survival reaching statistical significance. However, a propensity-matched model demonstrated no significant difference in cause-specific survival between patients who received radiation and those who did not. Conclusion. Sarcomas, a heterogeneous group of malignant mesenchymal tumors, are uncommonly found in the head and neck. This study represents the largest analysis of patients with head and neck sarcomas in the literature and demonstrates the impact of age, gender, primary site, histology, and radiation status on overall prognosis.Otolaryngology Head and Neck Surgery 08/2014; 151(4).
