Between 1977 and 1987, 19 patients were candidates for resection of lung metastases from pretreated extrathoracic primary tumours. Primary tumours comprised 10 osteosarcomas, one Ewing sarcoma and eight soft tissue sarcomas. All 19 patients presented with metachronous metastases. Twenty-eight thoracotomies were performed in these 19 patients. Nine patients underwent multiple surgical explorations. All the metastases were removed by wedge resection. Seven out of 10 patients treated for osteosarcoma received pre- and postoperative chemotherapy, and three out of 10 postoperative chemotherapy only. The projected survival rate at 3 years is 33%. Seven out of 19 patients survived more than 2 years; four of them were free of disease at 33, 54, 56 and 137 months. Good prognosis appears to be long metastases-doubling time, metachronous metastases, small number of lung metastases, pathological evidence of tumour necrosis and/or fibrosis after chemotherapy and, of course, complete control of the primary tumour and no extrathoracic metastases.

From June 1983 to December 1985, thirty-eight patients with localized Ewing's sarcoma of the extremities were treated with a protocol that consisted of an initial nine week period of polychemotherapy (vincristine, adriamycin and cyclophosphamide) followed by local therapy and additional chemotherapy (vincristine, adriamycin, cyclophosphamide and dactinomycin) for one year. As local treatment all patients were offered surgery; thirty-two accepted and six refused. These six patients were locally treated with radiotherapy alone (50 Gy). In the remaining patients an amputation was performed in one case and a resection in thirty-one. In resected patients when a wide margin was achieved (24 cases) no further local treatment was performed; when it was marginal (5 cases) or intralesional (2 cases) radiotherapy at lower doses (40 Gy) followed. At mean follow-up of thirty-seven months the percentage of continuously disease-free patients was 50% for those treated with radiotherapy, 76% with surgery, and 85% with surgery and radiotherapy. Eight patients developed metastatic disease and two patients had local recurrence and metastases. The local recurrences were seen in one patient locally treated with surgery and in one locally treated with radiotherapy. Nine major local complications were observed: three in patients treated with radiotherapy, five in patients treated with surgery, and one in a patient treated with surgery and radiotherapy. These results indicate that after induction chemotherapy conservative surgery is possible in almost all cases of Ewing's sarcoma of the extremities and that such treatment is better than radiotherapy alone as local therapy.

From September 1984 to March 1989, 57 children received intraoperative radiotherapy as part of a multidisciplinary tumor treatment. Their age ranged from 2 to 18 years. Tumor types: osteosarcoma, 21; Ewing's sarcoma, 19; soft tissue sarcomas, 6; neuroblastoma, 5; Wilm's tumor, 3; Hodgkin, 1; glioma, 1, and malignant pheochromocytoma, 1. In 44 patients the disease was localized while 13 had distant metastases. Intraoperative radiotherapy was used in 48 previously untreated patients as part of a radical treatment program and in 9 cases as an effort to rescue local failures (5 in previously irradiated areas). The intraoperative radiation field included the surgically exposed tumor or tumor bed, and the single doses ranged from 10 to 20 Gy, with 6-20 MeV electrons. With a median follow up time of 25 months (4 to 51 + months) 44 out of 57 patients are alive without local recurrence and 13 have died from tumor (6 with local progression). Intraoperative radiotherapy seems to be a feasible treatment which might promote local control in pediatric tumors.

As part of two sequential protocols using intensive combined modality treatment in pediatric and adolescent sarcomas, 31 consecutive patients with primary chest wall tumors were treated between November 1977 and March 1986. This group included 13 patients with peripheral neuroepithelioma (Askin's tumor), 11 patients with Ewing's sarcoma, 3 patients with rhabdomyosarcoma, and 4 patients with undifferentiated sarcomas. Following complete work-up, 17 patients presented with localized disease and 14 patients presented with metastases. Patients received intensive combined modality treatment with combination chemotherapy (vincristine, cyclophosphamide, Adriamycin, +/- actinomycin-D and DTIC) and high-dose conventionally fractionated radiation therapy to the primary (55-60 Gy) and non-pulmonary metastases (45-50 Gy). Radiation techniques used for the primary chest wall tumor varied with the clinical presentation. Patients achieving a complete response received either low-dose fractionated TBI (1.5 Gy/0.15 Gy fx/5 weeks) or high-dose TBI (8 Gy/4 Gy fx/2 days) and an intensive cycle of chemotherapy followed by autologous bone marrow transplantation. Twenty-five of 31 patients were judged to have a complete response (including 1 patient with complete resection). With minimum follow-up of 6 months and median follow-up of 36 months from completion of treatment, 14 patients remain disease-free with 2 additional patients alive in second remission after relapse. Patients with localized disease at presentation have improved disease-free survival and overall survival compared to patients with metastases at presentation. All 17 localized patients achieved a CR and 11 are NED compared to 8 of 14 metastatic patients achieving a CR and only 3 are NED. There have been 5 loco-regional recurrences with 3 "in-field" failures and 2 failures in the regional pleura. There were no treatment-related deaths and no clinically significant cases of pneumonitis. To date, 2 patients have significant treatment related morbidity, including 1 patient with scoliosis requiring surgery and 1 patient with acute leukemia developing 42 months after the start of therapy (presently in remission). We conclude that this intensive combined modality therapy results in a high CR rate and good local control with acceptable morbidity. Patients with metastatic disease at presentation remain a therapeutic challenge.

Chemotherapy has had a major impact in malignant bone tumors. In osteosarcoma, metastasis-free survival has been achieved in approximately 50 to 75 per cent of patients. Additional improvement based on the altered pattern of pulmonary metastases has also been reported. Preoperative chemotherapy has facilitated surgical resection of the primary tumor. The effects on the primary tumor may be utilized as a predictive factor and to design postoperative adjuvant therapy. Similar results have been achieved in Ewing's sarcoma with survival rates in the vicinity of 50 to 80 per cent. The interaction of chemotherapy with radiation has augmented the ability to achieve local control of the primary tumor. The tumoricidal properties of chemotherapy in destroying micrometastases may possibly also contribute to local control. Finally, initial treatment with chemotherapy may yield a complete response and facilitate definitive surgical treatment of the primary tumor. This may eliminate the need for radiation therapy and its delayed consequences.

Phase II studies using ifosfamide both alone and combined with vindesine and cisplatin have shown the effectiveness of this drug in patients with Ewing's sarcoma (ES) who had relapsed during VAC (vincristine, actinomycin, cyclosphosphamide)/VAd (vincristine, Adriamycin) therapy. In November 1984, these results led the SFOP to adopt a protocol consisting of (1) initial chemotherapy with three cycles of IVA (ifosfamide, 3 g/m2 on days 1 and 2; actinomycin D, 750 mg/m2 on days 1-3; vincristine, 1.5 mg/m2 on day 1) alternating every 3 weeks with IVAd (vincristine on day 22; ifosfamide on days 21-23; Adriamycin, 60 mg/m2 on day 22); (2) radical surgery if possible; (3) local radiotherapy (RT); and (4) maintenance chemotherapy with alternating IVA and VAd (vincristine, Adriamycin) for up to 9 months. In May 1987, 87 patients with previously untreated ES entered the study; 61 had localized ES. To date, 54 patients with localized disease and 22 with metastatic disease have finished initial chemotherapy; 40 patients with localized disease have been evaluated. In all, 28 patients (70%) were in complete remission (17 patients) or had a tumor regression of greater than 50% 11 patients) and were considered to be good responders; 12 patients were considered to be poor responders. After local radiotherapy in all but 7 patients and surgical resection in 29, 52 of 54 were considered to be in clinical remission. A total of 13 patients with metastatic disease were good responders at the completion of the initial chemotherapy. These results confirm the efficacy of primary chemotherapy using ifosfamide for the treatment of ES.

Chest-wall resection can be performed with low morbidity and mortality rates and remains the primary treatment for most chest-wall tumors. However, some lesions are best treated with a multimodality approach including preoperative chemotherapy. Therefore, pretreatment tissue diagnosis is essential in planning. The biopsy should be done at the medical center where the definitive treatment will be undertaken, and frequently, a needle biopsy will be sufficient. Osteosarcoma, rhabdomyosarcoma, Ewing's sarcoma, and other small-cell sarcomas are sensitive to chemotherapy, which should be given preoperatively, continued postoperatively, and modified according to the tumor response. Chondrosarcomas and most adult soft-tissue sarcomas are well controlled by primary excision and selective use of adjuvant irradiation. Better systemic and local therapy is needed for the recurrent soft-tissue sarcomas and the aggressive unclassified sarcomas. Chest-wall resection continues to play a primary role in the management of locally and regionally recurrent breast cancer but is best combined with systemic chemotherapy. Chest-wall resection can provide a long disease-free survival in patients with isolated metastases from sarcomas or carcinomas. In addition, significant palliation can be afforded patients with symptomatic chest-wall metastases and a shortened life expectancy.

From September 1984 to July 1987, 33 children received intraoperative radiotherapy as part of a multidisciplinary tumor treatment. Their age ranged from 2 to 17 years. Tumors types: Ewing's sarcoma (n = 11), osteosarcoma (n = 8), soft tissue sarcomas (n = 5), Wilms' tumor (n = 3), neuroblastoma (n = 3), malignant pheochromocytoma (n = 1), Hodgkin's disease (n = 1), and optic nerve glioma (n = 1). In 25 patients the disease was localized while 8 had distant metastases. Intraoperative radiotherapy was used in 26 previously untreated patients as part of a radical treatment program and in 7 cases as an effort to rescue local failures (5 in previously irradiated areas). The intraoperative radiation field included the surgically exposed tumor or tumor bed, and the single doses ranged from 10 to 20 Gy, with 6-20 MeV electrons. Patients with osteosarcoma and recurrent tumor in a previously irradiated area did not receive postoperative external beam radiotherapy. With a median follow-up time of 10 months (1 to 31 + months) 24 out of 33 patients are alive without local recurrence and 9 have died from tumor (5 with local disease progression). Intraoperative radiotherapy seems to be a feasible treatment which might promote local control in pediatric tumors.

Fourteen patients with extraosseous Ewing's sarcoma were evaluated by computed tomography (CT) and conventional radiography. The sites of involvement were in the lower extremities (six cases), the chest wall (four), pelvis (two), and the paravertebral region (two). In seven cases, the initial contrast-enhanced CT disclosed a necrotic soft tissue mass in four, two of them with peripheral enhancement. In three cases, the mass was homogeneous and did not enhance. CT enabled us to detect the size of the mass, the integrity of adjacent bone and medullary cavity, and to determine the presence or absence of metastases. CT was useful for evaluation of the patients' tumor response to treatment. In three of four patients treated with chemotherapy, CT showed evidence of a dramatic initial response. In one patient who was resistant to chemotherapy, surgical methods were required.

Fifty patients at the Mayo Clinic (Rochester, MN) from 1935 to 1985 met the histologic criteria for extraosseous Ewing's sarcoma. Forty-two had soft tissue primaries without bony involvement and formed the basis for this retrospective study of the clinical behavior and management of extraosseous Ewing's sarcoma. There were 19 male and 23 female patients (mean age, 22 years). Metastases were documented in 30 of the patients, six at the time of presentation and 24 occurring up to 11 years later, most commonly to lungs or bone. Three patients were lost to follow-up. Sixteen of 35 patients (46%) had local recurrence. Overall survival was 15 of 39 (38.5%) at 5 years. Decreased survival was noted with pelvic tumors, incomplete resections, and presence of metastatic disease, whereas increased survival was associated with wide surgical resection with negative microscopic margins, adjuvant local radiation therapy, and presentation since 1970 (48% 5-year survival compared with 28% before 1970).
