Cancer in patients receiving dialysis

Area of Science:

• Nephrology
• Oncology
• Immunology

Background:

• Chronic renal failure (CRF) is associated with altered immune function.
• Cancer incidence in patients undergoing dialysis requires further investigation.

Purpose of the Study:

• To investigate cancer incidence and mortality in patients receiving dialysis.
• To determine if specific cancer types are more prevalent in this population.

Main Methods:

• A 10-year observational study of 1651 patients across six UK dialysis centers.
• Analysis of cancer incidence and mortality compared to expected rates.

Main Results:

• A significant excess of non-Hodgkin's lymphoma (NHL) was observed (4 cases vs. 0.15 expected, p < 0.001).
• A significant excess of NHL-related deaths was also noted (3 deaths vs. 0.1 expected, p < 0.001).
• This excess was not linked to transplantation or immunosuppressive drug use.

Conclusions:

• Immunosuppression, a characteristic of CRF, may contribute to the development of NHL.
• Other reported cancer excesses in dialysis patients may be influenced by enhanced detection methods.
