title: Multiple malignant tumours in the elderly.
abstract: Aging of the population and technical improvements may contribute to increase the possibility of multiple malignant tumours to be diagnosed. Over a period of 18 years, 2,749 consecutive autopsies of elderly patients were performed. In addition to macroscopic examination of every single organ, bone marrow and prostate were routinely stained and microscopically examined. One hundred and sixty-seven patients with multiple malignant tumours were found. Mean age was 81.1 years for females and 80.1 years for males. Mean interval between tumours was 2.4 years for females and 1.0 year for males. First tumours were most of the time diagnosed clinically (n = 121 vs. 46) whereas second tumours were diagnosed at autopsy (n = 121 vs. 46). Origin and metastastic sites of tumours were not different between the first and second tumour. Prostate and breast were the most frequent organs involved in males and females. Multiple malignant tumours in the elderly are not rare and the second tumour is frequently diagnosed after death despite occurring relatively soon after the diagnosis of the first tumour. Multiple malignant tumours may represent a significant clinical challenge leading to further diagnostic procedures and differentiated therapeutic approaches.
