Cancer Incidence in People With Glomerular Disease: A Population-Level Study
Jialin Han1, Mark Canney2, Yinshan Zhao3
1Division of Nephrology, Department of Medicine, University of British Columbia, Vancouver, British Columbia, Canada.
Summary
People with glomerular disease (GN) face a significantly higher cancer risk, especially younger individuals. This highlights the need for increased awareness and tailored cancer screening strategies for GN patients.
Area of Science:
- Nephrology
- Oncology
- Epidemiology
Background:
- Glomerular disease (GN) may increase cancer risk, but existing studies lack clarity.
- Understanding cancer risks in GN patients can inform screening and identify modifiable factors.
Purpose of the Study:
- To identify cancer risk factors in Canadian patients diagnosed with glomerular disease (GN).
Main Methods:
- Retrospective observational cohort study of 4,039 adults with diagnosed GN in British Columbia (2000-2020).
- Analyzed known cancer risk factors and GN-specific factors (e.g., eGFR, proteinuria).
- Calculated standardized incidence ratios (SIRs) and used survival models for time-to-event analysis.
Main Results:
- The 20-year cancer risk was 23%, with a 30% higher incidence rate than the general population (SIR 1.3).
- Cancer risk was markedly higher in patients under 40 (SIR 2.9).
- Increased incidence observed for lymphoma (SIR 3.5), kidney (SIR 2.6), colorectal (SIR 2.4), and lung cancers (SIR 1.5).
Conclusions:
- GN patients have a substantially increased cancer risk, particularly younger individuals.
- Findings suggest a need for heightened awareness and development of targeted cancer screening and prevention strategies for GN patients.
- Age, male sex, baseline eGFR, and GN disease type were independent predictors of cancer risk.

01:28Drug Dosing in Renal Diseases: Estimation of Glomerular Filtration Rate Based on Serum Creatinine Concentration
298
Glomerular filtration rate (GFR) can be estimated from serum creatinine using the modification of diet in renal disease (MDRD) formula or the chronic kidney disease–epidemiology collaboration (CKD–EPI) equation. Both methods are widely used in clinical practice to assess kidney function and guide treatment decisions.The MDRD equation does not require weight or height measurements and is normalized to the body surface area of 1.73 m², considered the average adult surface area.

The glomerulus and Bowman's capsule are two essential components of the nephron, which is the functional unit of the kidney. These microscopic structures play a critical role in the process of blood filtration to produce urine.
Glomerulus: Structure and Function
The glomerulus is a tiny, intricate network of capillaries located at the beginning of the nephron. It's enveloped by the Bowman's capsule and receives its blood supply from an afferent arteriole, which divides into numerous...

Chronic kidney disease (CKD) requires collaborative and comprehensive management. CKD progresses through stages and can lead to end-stage kidney disease (ESKD) if untreated. Interprofessional collaboration and patient education are crucial, enabling patients to manage their health and improve their quality of life.Diagnostic approach for chronic kidney diseaseThe diagnosis of CKD primarily focuses on the glomerular filtration rate (GFR), which assesses kidney function by measuring how well...

Chronic Kidney Disease (CKD) progressively impairs multiple body systems due to the accumulation of uremic toxins, which disrupt cellular functions across various organs.Neurologic symptomsNeurologic symptoms often arise early in CKD, as uremic toxin buildup drives changes in cognitive and motor functions. Patients frequently experience fatigue, headache, confusion, difficulty concentrating, and, in severe cases, seizures. Peripheral neuropathy commonly manifests as burning sensations in the...

The glomerular filtration rate (GFR) is a critical indicator of kidney health, reflecting how well the kidneys filter blood. Changes in GFR can signal potential kidney impairment, necessitating accurate measurement methods to monitor kidney function effectively.Various molecules can serve as markers for GFR measurement, with the ideal marker meeting several specific criteria. It must freely filter at the glomerulus, avoid reabsorption or secretion by the renal tubules, remain unmetabolized, not...

01:17Factors Affecting Renal Clearance: Renal Impairment

Renal dysfunction significantly impairs the renal clearance of drugs, leading to potential complications in drug therapy. Renal failure, which can be caused by various factors, poses a significant challenge in the elimination of drugs from the body.
One condition associated with renal failure is uremia. Uremia is characterized by impaired glomerular filtration and fluid accumulation in the body. This condition hinders the renal clearance of drugs, resulting in drug accumulation and potential...
