Connection Between Kidney Cancer and Tobacco Use: A Closer Look

Connection Between Kidney Cancer and Tobacco Use: A Closer Look

In the world of cancer, kidney cancer ranks as the 14th most common, with the highest incidence found in Western countries [1]. Renal cancer, as it is commonly known, can manifest in various forms, including renal cell carcinomas (RCCs), transitional cell carcinomas (TCCs), and Wilms' tumours. This article will focus on TCCs, a less-discussed but significant subtype of kidney cancer [1].

TCCs originate in the tissue lining of the kidneys, particularly in the urinary tract. Unlike RCCs, which develop in the filtering tubules of the kidney, TCCs arise specifically in the renal pelvis, the part of the kidney where urine collects [1].

Factors influencing the incidence of kidney cancers, including TCC, align with known kidney cancer risk factors such as smoking, obesity, hypertension, genetic predispositions, and chronic kidney disease [2].

Smoking, a global health issue, is a major contributor to the onset of many cancers, including kidney cancer. The risk increases with longer duration and intensity of smoking [2]. Obesity, another significant factor, is associated with higher kidney cancer risk due to related metabolic and hormonal changes [2].

Hypertension (high blood pressure) is linked to increased kidney cancer incidence [2]. Genetic conditions, such as von Hippel-Lindau disease and Birt-Hippel-Dube syndrome, increase an individual's susceptibility to kidney cancer [2][3]. Prior radiation, especially in women treated for reproductive cancers, may also elevate kidney cancer risk [2].

Chronic kidney disease and long-term dialysis are known to increase the risk for kidney cancers, including potentially TCC, due to ongoing renal damage and regeneration cycles [2].

Specific trends in TCC incidence are less detailed in the current sources, but because TCC originates in the urinary tract lining, exposures linked to urothelial carcinomas—such as smoking and certain chemical exposures—likely influence TCC incidence. Common symptoms include blood in the urine (hematuria), which is a hallmark for TCC and other urothelial cancers [4].

Current trends in kidney cancer overall emphasize advances in precision medicine, including biomarker-driven personalized treatments and the investigation of the gut microbiome’s influence on cancer outcomes; however, these advances focus largely on RCC rather than TCC specifically [1][3].

In sum, while recent research and treatment innovation mainly focus on RCC, the incidence of TCC in the kidney is influenced by established risk factors shared with kidney and urothrial cancers, especially smoking, obesity, hypertension, genetic predispositions, and chronic kidney injury. Emerging precision medicine approaches have not yet specifically targeted TCC of the kidney but are advancing the broader field of kidney cancer care [1][2][3][4].
