[Prognostic importance of biochemical and cytological indices of the sputum in lung cancer].

Based on a clinico-cytological correlation of the findings, obtained kinetically in multiple examination of sputum and biochemical assays of blood, in 102 patients with lung cancer there were revealed some prognostic factors. So, the increased level of sialoacid and the presence of C-reactive protein in blood serum, macrophage reaction and the character of inflammatory changes in the lung as shown by sputum, which accompany and characterize the pathological process, may be used for prognostication only together with the clinical course indices.
