[Association of primary malignant neoplasms in the same patient]

Abstract

The Authors have examined the problem concerning the presence of "Double malignancies" in the same patient, on the basis of a review of the literature and of an investigation of their own case material (nine patients: six with double solid tumours and three with a solid tumour and an associated haematologic neoplasia). The Authors discuss the time sequence of the two neoplastic processes and the immunological pattern (T and B lymphocytes) of all cases.
