Inflammatory Networks in Renal Cell Carcinoma

Area of Science:

• Oncology
• Immunology

Background:

• Cancer-associated inflammation is a hallmark of solid tumors, regulated by extrinsic and intrinsic signaling pathways.
• Tumor-extrinsic inflammation arises from factors like infection and obesity, while intrinsic inflammation stems from genomic alterations and epigenetic changes within cancer cells.
• In renal cell carcinoma (RCC), intrinsic alterations upregulate inflammatory pathways, promoting tumor growth and immune evasion.

Purpose of the Study:

• To review the molecular mechanisms of cancer-associated inflammation in influencing cancer and immune cell functions.
• To explore how inflammation increases tumor malignancy and anti-cancer resistance.
• To discuss the potential of anti-inflammatory treatments for clinical benefits in RCC.

Main Methods:

• Literature review of molecular mechanisms in cancer-associated inflammation.
• Analysis of intrinsic and extrinsic factors contributing to inflammation in RCC.
• Discussion of therapeutic strategies targeting inflammation in RCC.

Main Results:

• Cancer-intrinsic alterations in RCC activate inflammatory pathways, enhancing chemokine release and neoantigen expression.
• Immune cells and inflammatory loops amplify tumor growth and progression in RCC.
• The tumor microenvironment, influenced by inflammation, exhibits dual roles in promoting or inhibiting tumor growth.

Conclusions:

• Understanding the pathomechanisms of cancer-associated inflammation is crucial for therapeutic success in RCC.
• Anti-inflammatory treatments hold potential for clinical benefits in RCC.
• Further research into anti-inflammatory strategies is warranted for RCC therapy.
