Objective To compare the epidemiology, local and regional invasion and prog
nosis of head and neck malignant fibrous histiocytoma (MFH) and extremity M
FH.
Methods Between January 1, 1972 and December 31, 1993, 173 patients with MF
H (71 head and neck, 102 extremities and trunk) were referred to the Cancer
Hospital for surgical treatment. They were 101 men and 72 women, with age
ranging from 13 to 83 years (median: 45 years). The extent of surgery was c
lassified into radical, wide and local resection.
Results For head and neck, local recurrence of MFH after wide resection was
80.4% (37/46), compared with 36.4% (8/22) after radical surgery (P = 0.000
). The five-year survival was 50.79% in all the head and neck patients (74.
75% in patients free of local recurrence, 37.74% in patients with local rec
urrence; P = 0.0181), compared with 70.71% in extremity patients (P = 0.000
5). Repeated surgery after recurrence of MFH could cure 40.9% of the head a
nd neck patients and 80.7% of the extremity patients.
Conclusion Inadequate resection of head and neck MFH in initial surgery is
associated with a high incidence of local recurrence, which is always corre
lated with worse prognosis. Repeated surgery for recurrent head and neck MF
H is not as effective as for recurrent extremity MFH. Therefore, we suggest
that the initial surgery for head and neck MFH should be as radical as all
owed to avoid a possible local recurrence.
