Metastatic patterns in osteosarcoma.

The clinical courses of 193 patients with high-grade, non-metastatic osteosarcoma were reviewed to ascertain the evolution of the natural history of the disease. All patients had the primary lesion in the extremities and were treated at the Rizzoli Orthopaedic Institute between 1976 and 1982 with surgery alone (30 cases) or surgery plus adjuvant chemotherapy (163 cases). All patients were regularly followed at our Institute. One hundred and fourteen patients, of which 27 were treated with surgery alone and 87 treated with adjuvant chemotherapy, developed overt metastatic disease. No differences were found concerning the sites of the first relapse which, for approximately 90% of cases, were lungs in both groups. However, in the group of patients treated with adjuvant chemotherapy the development of overt metastatic disease, as compared to non-adjuvant patients, was delayed with time (13 vs 8 months) and the number of metastatic nodules in the lung at first relapse was reduced. This alteration in metastatic pattern due to adjuvant chemotherapy is important because it allows surgical resection of pulmonary metastases in a larger number of patients (51% vs 29%).

[Usefulness of stratigraphy and computerized tomography in the initial staging of osteosarcoma of the extremities. Retrospective study of 217 cases].

The value of stratigraphy and pulmonary CT in the initial work-up of osteosarcoma of the extremities is assessed with reference to 217 patients encountered in the Bone Tumour Centre of Rizzoli Orthopaedic Institute in May 1983-May 1986. Stratigraphy revealed lung metastases not identified by standard radiography in 4 patients (1.8%), while CT revealed metastases not identified by either standard X-rays or stratigraphy in a further 6 cases (2.7%). It is concluded that the increase in the percentage of cures (about 30%) reported in the last 10 years in osteosarcoma cases given adjuvant chemotherapy cannot be explained by any difference in initial selection due to the use of these techniques that were not adopted in the historical series.

Complications of pelvic resections.

The authors report on complications that occurred with 63 pelvic resections. There were 43 complications: 13 infections, seven cases of nerve palsy, 12 cases of vascular or visceral damage, six mechanical and five aesthetic complications. Infection and vascular and visceral damage were more frequent in anterior arch resections, neurological damage in iliac wing resections, and mechanical complications in periacetabular resections. The treatment and outcome of the complications are reported.

[Resection with preservation of the lower limb in chondrosarcoma of the pelvis].

Twenty-seven chondrosarcomata of the pelvis were treated by local resection with preservation of the limb. Twenty-two were grade I or II, and 5 were grade III or IV. Attention is drawn to the importance of tomodensitometry in assessing the extent of the tumor before operation. An en bloc resection was well wide of the tumour in 16 cases, close to the tumour in 10 cases and involved the tumour in one case. Post-operative complications were varied. There were 6 nerve paralyses after iliac resection, 3 cases of sepsis after resection of the anterior part of the pelvic ring, and 3 cases of sepsis and 2 vascular complications after peri-acetabular resections. The average follow-up was 5 years. Three had metastases and three had local recurrences, one of whom died later from pulmonary metastases. No local recuRrence was seen in cases with wide resection. The functional results were satisfactory in 6 out of 7 partial resections of the ilium and in 4 out of 5 resections of the anterior part of the pelvic ring. They were only fair after peri-acetabular resections and complete resections of the ilium. After peri-acetabular resections, the results were about the same after ilio-femoral arthrodesis or Girdlestone operations. It is not appropriate to reconstruct the pelvic ring after resection limited to the anterior part of the pelvis but it is indicated after resections of the whole of the ilium, particularly in children to avoid shortening of the limb with pelvic shift.

[Pelvio-perineal recurrence after amputation of the rectum for cancer. Considerations on diagnosis and treatment].

The authors analyse pelvi-perineal recurrence after amputation of the rectum on the basis of 47 cases followed for a minimum of two years, 10 of which developed recurrences. The diagnosis, always difficult and delayed, can be made earlier by using pre-operative computed tomography. However, the recurrences can be resected in only a limited number of cases. The routine use of more radical operations and extensive lymphadenectomy and the decreased use of mechanical sutures have not improved the results. The essential approach must therefore consist of the detection of stage A tumours and precancerous lesions followed by adaptation of the resection technique according to the degree of extension of the tumour.
