A 12 1/2-year-old female presented with
Ewing's sarcoma
of the manubrium sterni which extended into the anterior mediastinum. At presentation there was no evidence of
metastatic disease
. Her initial treatment consisted of radiation therapy and chemotherapy. The residual tumor was subsequently resected and the sternal defect was repaired with Marlex mesh. Postoperatively, she was maintained on chemotherapy consisting of BCNU, cyclophosphamide, and adriamycin. The adriamycin was discontinued after she developed sterile fibrinous pericarditis. She remains free of her disease two years after diagnosis. Although extremely rare, Ewing's does occur in the sternum and this area is amenable to wide local resection without severe functional disability.

Twenty-one patients with pathologically proven
Ewing sarcoma
without overt
metastases
at diagnosis were treated with a protocol designed by the Royal Marsden/St. Bartholomew's Hospitals Children's Solid Tumour Group (CSTG). They received megavoltage radiotherapy to the involved bone and adjuvant chemotherapy with a combination of four cytotoxic drugs. Seven patients have so far relapsed, four at the original site and three in other bones. The other 14 are clinically free of disease a median of 36 months from diagnosis. Comparison with a historical control group of 19 patients treated with surgery or radiotherapy, but without initial chemotherapy, shows a significant improvement in survival for the study group (P = 0.03). Seventeen of the controls have died. The treatment regime was moderately toxic, but there were no treatment-related deaths. These results confirm that an improved survival time and hopefully cure rate can be expected from treating Ewing tumour with high doses of megavoltage radiation and combination chemotherapy. Future goals must be the better control of large primary lesions and the eradication of micrometastases in other bones. The place of surgery should be re-evaluated in the treatment of the primary tumour, and better adjuvant chemotherapy regimes are needed.

The series consisted of 132 patients, 61 with primary bone sarcomas and 71 with primary soft tissue sarcomas. The patients were all evaluated by lymphography. The investigation included both patients who had not yet been treated and patients with suspected or confirmed
metastases
. All tumour diagnoses were confirmed microscopically. The findings as regards dissemination were based on clinical examinations, laboratory tests, roentgen examinations and lymphographies. In some cases, lymph node biopsies and surgical observations were also used. A total of 151 lymphographies were performed and 281 follow-up films taken. Preoperative lymphography was performed using the technique introduced by Kinmonth. For postoperative lymphography on the stumps of amputated extremities, two simple but useful methods were developed, which are presented here. Changes in the lymphographic appearance of lymph node
metastases
, the occurrence of new
metastases
, and the results of treatment were assessed by survey films and repeat lymphography. The generally accepted criteria for metastasis were used as a basis for the analysis of the lymphographic findings. The results may be summarized as follows: 1. Incidence of lymphatic dissemination. Different sarcomas varied greatly in their clinical course, including the frequency of dissemination. The lymphatic involvement in the metastatic cases was as follows: Bone sarcomas: 16 out of 28 (Table 10); of these, 13 were to regional lymph nodes, 8 to distant nodes and 5 to both (Table 14). Soft tissue sarcomas: 24 out of 40 (Table 11). All 24 had
metastases
in regional nodes, and 8 in distant nodes as well (Table 15). The highest frequencies of lymphatic spread in the different metastasized tumours were found to be: Bone sarcomas: reticulosarcoma 100%,
Ewing's sarcoma
50%, osteosarcoma 47%. Soft tissue sarcomas: rhabdomyosarcoma 100%, synovial sarcoma 80%, neurogenic sarcoma 78%, leiomyosarcoma 67%. 2. Time-relation between lymphatic and haematogenic dissemination; The tendency to
metastasize
first via the lymphatics or via the blood vessels varied. Half of the cases of
Ewing's sarcoma
and reticulosarcoma had evidence of lymphatic spread before blood-borne
metastases
were detected. In the osteosarcoma cases, however, lymphatic dissemination was always preceded by haematogenic spread (Table 12). In synovial sarcoma, rhabdomyosarcoma and neurogenic sarcoma, the first dissemination was more frequently lymphatic than haematogenic (Table 13). 3. Possible existence of special lymphographic features of sarcoma
metastases
. Only reticulosarcoma displayed special characteristics. The lymph node
metastases
of reticulosarcoma of bone had lymphographic appearances similar to those found in reticulosarcoma of soft tissue or lymph node origin (Fig. 12). The lymph node
metastases
of other primary bone and soft tissue sarcomas had no specific lymphographic features and were indistinguishable from carcinomatous
metastases
(Figs 7, 9, 13, 15, 18, 19, 20, 22, 23). 4...

At the Princess Margaret Hospital, Toronto, during the period 1960 to 1975, radiation therapy was given to 59 patients with
Ewing's sarcoma
without overt
metastases
. Over this period treatment was modified to include, as well as irradiation to the primary tumour, total body irradiation (TBI) and chemotherapy according to various regiments. The 5-year survival rate of 38% in 26% patients who received TBI suggests that this may be of value. In patients with osteogenic sarcoma preoperative irradiation was not found to be of value. Recently the resection of pulmonary
metastases
combined with chemotherapy has increased the survival rate. When the primary site makes resection impracticable, the response to irradiation and chemotherapy is encouraging. Three cases so treated are described.

An accurate pathological diagnosis must be made prior to treatment of a primary malignant bone tumour. Consideration must be given to the clinical and radiologic aspects as well as the histology. Both benign and malignant tumours occur more frequently in certain decades. A search should be made for precursor lesions such as Paget's disease. The presenting manifestations of pain, a mass and dysfunction are not specific for tumours. Laboratory tests may be helpful, especially in distinguishing tumours from infections and metabolic diseases.
Metastasis
is usually via the blood stream to the lungs and bones. The low survival rate following amputation for osteosarcoma and radiation therapy for
Ewing's sarcoma
has been improved by chemotherapy. The lower-grade tumours such as aggressive giant cell tumour and low-grade chondrosarcoma can often by treated successfully by resection and insertion of an autograft, an allograft or a metallic implant.

We have reviewed the literature and described experience in treating
Ewing's sarcoma
and osteosarcoma before and during the era of intensive systemic chemotherapy. Local control of
Ewing's sarcoma
may relate to increasing doses of radiation, especially when intensive chemotherapy is administered also. Problems of radiation enhancement by chemotherapy have caused us to reconsider time-dose and volume parameters in treating these patients. The role of radiation in osteogenic sarcoma is limited to patients with inoperable lesions and
metastases
.

Between 1973 and 1978 combined radiotherapy and chemotherapy were given to 22 patients with histologically proven
Ewing's sarcoma
. The combined chemotherapy consisted of cyclophosphamide, vincristin, adriamycin, as well as dacarbazine in some cases. The neoplasm was a localized one at the beginning of treatment in 14 of the 22. These patients received high-voltage radiotherapy to the primary focus at a focal dose between 42 and 55 Gray (4200-5500 rad), followed by chemotherapy. After 6--8 treatment cycles, adriamycin was replaced by methotrexate. Nine of the 14 patients survived without recurrence for 12 to over 59 months. Eight patients had extensive
metastases
at the beginning of treatment: they at first received only chemotherapy, followed by radiotherapy or operation, as indicated. Full clinical remission was achieved in five of them: in three this remission has now lasted for more than 18, 40 and 44 months, respectively. These results indicate that (1) additional chemotherapy improves the prognosis of localized Ewing's sarcoma, and (2) even in far-progressed cases the combination of chemotherapy and radiotherapy can achieve lasting remission, which may in fact be a true cure.

All the pertinent radiographs of 83 patients with histologically proven
Ewing's sarcoma
were reviewed. Forty-nine patients were in the pediatric age group, and 34 were adults. The mean age, the symptoms and time from symptoms to diagnosis were evaluated in the 2 groups. The site of primary involvement was in 54% the long bones, 35% the flat bones, 8% the small bones and 3% extraosseous. For the primary site we considered the diagnostic results of the standard radiographic investigations and in some cases the usefulness of angiography, xeroradiography and telethermography. At presentation we also evaluated the possible diffusion of the disease with standard radiographic surveys (chest and skeletal, including limbs) and with foot lymphography in selected cases. In this way, 57 patients (69%) were considered to have localized disease. In this group, we also considered the value of the periodic radiographic follow-up, which enabled us to disclose the appearance of
metastases
(chest 64%, bone 54%, lymph nodes 11%) in 28 cases (49%). Finally, we made a comparison of the different radiologic and epidemiologic findings between children and adults.

2 patients with
metastatic cancer
(
Ewing's sarcoma
and breast cancer) developed pleural effusions while undergoing systemic therapy for pulmonary
metastases
. Thoracenteses failed to reveal malignant cells and in both instances the characteristics of the fluids were those of transudates. The effusions developed in association with dissolution of pulmonary lesions and presumably represent a reactive process to tumor regression.

A 39-year-old man had pain and swelling of the terminal phalanx of a finger. Radiograph was interpreted as osteomyelitis, and amputation through the mid-phalanx was performed. Histology revealed
Ewing sarcoma
. Lung metastases rapidly developed. Right lung irradiation and systemic chemotherapy, including doxorubicin, were instituted. He developed progressive severe right ventricular failure which was attributed to effects of large pulmonary
metastases
. Autopsy showed massive right ventricular
metastases
, the primary pathological cause of the heart failure, without evidence of doxorubicin cardiomyopathy.
