[Osteochondrosarcoma: clinical and morphological comparisons].
A total of 109 patients with chondrosarcoma were operated on in 2005-2007. Classical primary chondrosarcoma was verified in 77 cases; secondary and periosteal chondrosarcomas were confirmed in 28 and 4 patients, respectively. By analyzing their findings and the data available in the literature, the authors considered the current problems in the classification and diagnosis of the most common types of cartilaginous malignancies. New techniques, including cytogenetic assay, significantly alleviate this problem. However, the most precise cytogenetic assays are expensive and not always accessible for usual oncological care. The principal criteria in practice are a clinical picture, the results of radiation studies, and the standard histological method that establishes the differentiation of chondrosarcoma, the extent of a process, and the specific features of tumor growth. Immunohistochemical assay are of no crucial importance. In some cases, fine-needle biopsy may provide useful information to make a decision on treatment policy.
