[Basement membranes in precancerous conditions and neoplasms of the uterine cervix].
By routine histological staining technics and histochemical assays under an appropriate enzymic control the author has studied changes in the basement membranes of the uterine cervix in its precancer and cancer as compared with the normal state. Changes in the basement membranes, revealed morphologically, reflect objectively the status of the epithelium and stroma during the period of tumor origination and growth, and therefore these may serve as a valuable adjunct to the differential microscopic diagnosis of dysplasia, preinvasive cancer and an incipient invasive growth. It is believed that basement membrane neoplasms may develop around mostly differentiated complexes of cancer cells in far-advanced neoplasms and their metastases; this fact is regarded as a tendency to normalization of the relationship between the cancerous tumor parenchyma and stroma with correlations between them being remined even under extremely unfavourable conditions of the tumor growth.
