Colorectal tumors diagnosed in patients after renal transplantation — case reports

Abstract

Colorectal cancer is one of the most common types of solid tumors occurring in adults. It is known that kidney transplantation is associated with greater risk of developing cancer. Detection of cancer in a patient after kidney transplantation is associated with worse prognosis compared to a patient from the general population. It is necessary to conduct screening in order to detect potential proliferative lesions at an early stage of development, which greatly increases the chance of successful recovery. The article presents two clinical cases of kidney transplanted patients in whom cancer in advanced stage was diagnosed, which resulted in therapeutic failure.
