Multiple primary malignant tumors (MPMT) or polyneoplasia is one of the challenging and understudied categories in modern clinical oncology. The importance of studying MPMT is caused by such factors as growing cancer morbidity worldwide, increasing incidence of polyneoplasia, the need to make difficult decisions regarding further management strategies. The cause of the growing incidence of MPMT remains unclear. It appears that, in addition to the actual increase of the MPMT share in tumor statistics, improvement of diagnostic means in modern oncology plays a major part. Another important factor is the increasing life expectancy of patients with primary tumors due to improvement of chemotherapy and radiotherapy methods, which is associated with growing rates of detection of “second” tumors. There are also numerous risk factors predisposing to MPMT development (lifestyle, environment, genetic factors, age, antitumor immunity related factors).

This article describes a case of a 78 years old patient I.V. with multiple primary malignancies including malignant tumors of the bladder, ureter, kidney, prostate, stomach diagnosed over 8 years.
