Tracking Nongenetic Evolution from Primary to Metastatic ccRCC: TRACERx Renal

Area of Science:

• Oncology
• Genomics
• Immunology

Background:

• Clear cell renal cell carcinoma (ccRCC) is a complex malignancy.
• Understanding the drivers of ccRCC progression beyond genetics is crucial for effective treatment.

Purpose of the Study:

• To investigate non-genetic factors influencing ccRCC evolution.
• To identify novel therapeutic targets and improve clinical management strategies for ccRCC.

Main Methods:

• Joint genomic and transcriptomic analysis of 243 ccRCC samples.
• Analysis focused on identifying recurrent evolutionary patterns not solely explained by genetic alterations.

Main Results:

• Identified recurrent non-genetic evolutionary patterns in ccRCC.
• Observed T-cell depletion and tumor T-cell receptor coevolution.
• Found evidence of potential cGAS-STING pathway repression and increased cell proliferation.

Conclusions:

• Non-genetic factors play a significant role in ccRCC evolution.
• These identified patterns can inform clinical management and novel treatment strategies for ccRCC.
• Further research into these mechanisms may lead to improved patient outcomes.
