Abstract: | |
Osteosarcoma is one of the most frequent tumors in children and young people. In the present report we examined the data of 52 patients with osteosacoma during 1990-1997 at the National Institute of Oncology ( SOLCA). This tumors was more frequent in males (60%) than in females (40%). The age of more frecuence presentation of the tumor was between 12 and 17 pears, while the initial simpoms were local adema, eritema and pain, funtional troubles of the involved extremity, and sometimes pathological fracture. The more frequent localitation of osteosarcoma in our group was in the inferior extremities ( femur), and the time elapsed prior to the diagnosis was of 3 months, indicating the rapid clinical course of the disease. One of themain differences in our group in relation of other, is the histological type of the osteosarcoma, being the condroblastic type our cases, while the most frequent in dmedical publications in the osteoblastic type. Most of the patients of the group were submited to surgery, with pre and/or post-operatory quimiotherapy, mainly with the use of methotrexate. The results of the management of the group showed 14 patients with metastases at the diagnosis, another 14 cases with metastases during the treatment, 7 alive without tumor evidences, 2 alive with active metastases, and 17 lost during followup, while another 32 abandoned the treatment. The results shows the necessity for a better the cooperative management og such patients between clinicians and surgeons, in oder to improve the clinical results in patients with osteosarcoma in this institution.
