Abstract

The association between inflammatory cells, including tumor associated macrophage (TAM), mast cell (MC) and eosinophil Leucocyte (EL) densities and angiogenesis, as well as the relation of TAM, MC and EL densities and angiogenesis to tumor stage were investigated in specimens of 63 non-small cell lung carcinoma (NSCLC). Fifteen cases were in stage I, 12 were in stage II, 33 were in stage III and 3 were in stage IV. ELs and MCs were identified by hematoxilen-eosin and toluidine-blue histochemical stains, respectively. TAMs were shown by immunohistochemistry for CD68. Microvessets demonstrated by immunohistochemistry for CD31 were quantified by a stereotogical method and vascular surface density (VSD) and microvessel number (NVES) were calculated. There was not any statistically significant correlation between tumor's stage and VSD, TAM and EL counts. MC count and NVES were found to be higher, in early stages. VSD and NVES were not associated with EL, MC and TAM counts. The lack of consistent correlation of angiogenesis to the stage of disease in this study supports the view that tumor angiogenesis is not a significant prognostic factor in NSCLCs. The absence of correlation between MCs, ELs and TAM counts and angiogenesis and absence of any relation between ELs and TAMs and tumor stage are discordant with the results of some of the previous studies in NSCLCs and in other tumors. The differing results may be due to wide variations in methodologies which were used for demonstration of inflammatory cells and vessels and variations in the degree of activation and complexity of functions of these cells.
