[Stromal reaction on bronchial carcinoma].

The stromal reaction was analysed in histological preparations of 100 patients with bronchial carcinoma (bioptic material). The tumor-stromal reaction in all types of tumors is much greater than the stromal reaction of the surrounding area. A positive correlation exists between the stromal reaction and the histological type of tumor and the differentiation of the tumors. The differentiated tumors have a greater stromal reaction than less differentiated tumors. The stromal reaction should be used in the diagnosis of the types of bronchial carcinoma since it provides information about the tumor type from bioptic material.
