abstract...
Since May 1970, 67 consecutive patients with primary
(nonmetastatic) Ewing's sarcoma were treated with adjuvant
chemotherapy (CT) in addition to radiation therapy (RT) or
surgery for the primary tumor. The first 19 patients were
treated with four-drug sequential CT (T-2). The second
protocol was a seven-drug induction combination CT (T-6)
followed by T-2 maintenance CT; in both protocols CT was
continued for 18 months. The current protocol (T-9) consists
of combination CT given continuously for a period of 9 months.
Of the entire group of 67 patients, 47 (70%) had axial and
proximal lesions (pelvis, spine, rib, humerus, and femur) and
20 (30%) had distal lesions (forearm, leg, and foot); 53/67
(79%) are surviving free of disease 12--118 months (median 41
months) from the start of treatment. Fifteen of 23 (65%)
patients with axial lesions, 19/24 (79%) patients with
proximal lesions, and 19/20 (95%) patients with distal lesions
are free of disease. Disease-free survivors include 28/39
(72%) male patients and 25/28 (89%) female patients.
Thirty-four patients had RT, and 33 had surgery or surgery and
RT, in addition to chemotherapy, for local treatment. The
disease-free survival rate was 76% in the RT group and 82% in
the surgery group; failure in the RT group was attributable to
local recurrence in 7/34 (21%) patients. Recent experience
with T-9 CT has demonstrated that CT given prior to RT or
surgery can cause a great reduction in the size of the primary
tumor while allowing the pathologically-eroded bone to heal
prior to the initiation of RT; this also allows the high-risk
patient with an axial primary (pelvis or spine) to tolerate
the aggressive CT needed to prevent distant metastases. In
addition to dramatically increasing survival in patients with
Ewing's sarcoma, combination CT has helped achieve permanent
local control. The superior survival rates for all sites of
primary tumor are attributable to the early use of aggressive
combination CT.
