[13 cases of double neoplastic localizations, 1 involving the esophagus].
During the course of nine years 494 patients suffering from oesophageal cancer have come under our observation, including 13 cases characterised by the phenomenon of double neoplastic localisation. In some cases, in view of the histological identity of the two neoplasias, remote endocanicular colonisation may be presumed, while in other cases the rise of the tumour "disease" may be correlated with the action of carcinogenetic agents on sites of lesser resistance in organisms whose immunitary defences have been decreased in relation to neoblastogenesis. This is supported by the increase in the incidence of malignant neoplasias in patients subjected to immuno-suppressive treatment.
