Nc. Daw et al., Bone sarcomas of the head and neck in children - The St Jude Children's Research Hospital experience, CANCER, 88(9), 2000, pp. 2172-2180
BACKGROUND. Bone sarcomas of the head and neck are difficult to resect. The
authors reviewed their institutional experience with these tumors to chara
cterize patients' clinical findings and to assess the impact of surgical re
section on outcome.
METHODS. The records of the 28 patients with bone sarcomas originating in t
he head and neck treated at St Jude Children's Research Hospital between Ma
rch 1962 and January 1998 were reviewed.
RESULTS. There were 10 males and 18 females (median age, 12.6 years) each w
ith a single sarcoma: osteosarcoma (18), Ewing sarcoma (7), malignant fibro
us histiocytoma (MFH) (2), and fibrosarcoma (1). Primary tumor sites includ
ed the maxilla (13), skull (10), mandible (2), and other sites (3). All but
one patient with Ewing sarcoma had localized disease at the time of diagno
sis. All patients underwent surgery: complete resection, 8; gross total res
ection, 4; incomplete resection, 14; and biopsy only, 2; 22 also received c
hemotherapy. Radiotherapy was given to all patients with Ewing sarcoma and
to four patients with primary osteosarcoma. Twelve patients survived a medi
an of 8.4 years after diagnosis, 14 died of disease, and 2 died of unrelate
d causes. Local disease progression was evident in 12 patients (9 with oste
osarcoma, 2 with MFH, and 1 with Ewing sarcoma) who died of disease, 9 of w
hom had the initial treatment of biopsy alone or incomplete resection. Pati
ents with osteosarcoma who had the initial treatment of incomplete resectio
n or biopsy alone were more likely to experience local failure (P = 0.001)
and had poorer survival (P = 0.014) than those who underwent complete or gr
oss total resection.
CONCLUSIONS. Bone sarcomas of the head and neck are rare among children and
most often are localized at the time of diagnosis. Incomplete resection of
osteosarcoma is associated with local failure and poor outcome. Although a
ggressive surgery is essential for the cure of osteosarcoma, its necessity
in the treatment of Ewing sarcomas remains controversial. (C) 2000 American
