title: [Characteristics of metastatic lesions of the ribs from various sites of primary tumor process].
abstract: The paper is concerned with an analysis of the specificities of metastatic costal affection depending on the site of a primary tumor basing on a study of the skeleton scintigrams and scanograms of 2496 patients who were examined and treated in the All-Union Cancer Research Center, AMS USSR, in the period of 1980-1983. To assess the frequency of costal affection, the authors made use of an index of primary tumor metastasizing to the ribs (N. N. Trapeznikov, 1981) that reflects the ratio of the number of patients with costal metastases to the total number of patients with metastases. The analysis has shown that costal metastases are most frequently observed in breast carcinoma, prostatic and lung cancer. However, judging by the index of metastasizing tumors of the undetected primary focus come first, then head and neck tumors, and prostatic tumors. Costal metastases are observed 20% as more frequently in women than in men.
