[Clinical cytological characteristics of osteogenic sarcoma]. / Kliniko-tsitologicheskaia kharakteristika osteogennoi sarkomy.

The authors report the data on the disease clinical course being dependent on the peculiarities of tumor differentiation. The work is based on the findings of treatment and dynamic follow-up of 156 patients with osteogenic sarcoma of extremity bones. Distant gammatherapy, as the principal method of treatment, was employed in all patients. A cytological test was used to determine the morphological character of the tumor. It was shown that clinico-cytological correlations sometimes help to reveal significant differences in development of the disease. In groups of patients with signs of primary tumor anaplasia male individuals showing acute pains, prompt tumor growth and marked general intoxication phenomena were predominating. In radiotherapy of this group of patients a positive response, which may allow a continuous dynamic observation, is more rarely gained.
