The complement system and kidney cancer: pathogenesis to clinical applications.

Area of Science:

• Immunology
• Oncology
• Complement System Biology

Background:

• Kidney cancer exhibits resistance to conventional therapies and a propensity for metastasis.
• The kidney is susceptible to complement system dysfunction, which tumors can exploit.
• The complement system, traditionally viewed as extracellular, also functions intracellularly, influencing cancer progression.

Purpose of the Study:

• To review the multifaceted roles of the complement system in kidney cancer.
• To examine how complement proteins regulate the tumor microenvironment (TME), cell signaling, proliferation, metabolism, and immune response.
• To discuss the potential of complement-targeted therapies and combination strategies for kidney cancer treatment.

Main Methods:

• Literature review of recent discoveries on complement system function in cancer.
• Analysis of the role of complement proteins in kidney cancer progression.
• Examination of emerging immunotherapeutics targeting the complement system.

Main Results:

• The complement system plays a critical role in immune surveillance and defense, but is also implicated in cancer progression.
• Tumors exploit the complement system, influencing the TME and cellular processes.
• Complement inhibitors are a promising new class of immunotherapeutics.

Conclusions:

• Harnessing the complement system offers a promising avenue for effective kidney cancer treatment.
• Strategic combination of complement inhibitors with other cancer therapies may enhance treatment efficacy.
• Targeting the complement system provides renewed hope for kidney cancer patients.
