Postoperative Metabolic Phenoreversion in Clear Cell Renal Cell Carcinoma

Area of Science:

• Oncology
• Metabolomics
• Biochemistry

Background:

• Surgical tumor removal aims to restore patient health.
• Clear cell renal cell carcinoma (ccRCC) is a common kidney cancer.
• Metabolic alterations are associated with cancer progression and treatment.

Purpose of the Study:

• To evaluate a 16-lipid panel for discriminating ccRCC patients from healthy controls.
• To investigate metabolic changes in ccRCC patients before and after nephrectomy.
• To identify lipid biomarkers for predicting patient prognosis and treatment outcomes.

Main Methods:

• Analysis of paired serum samples from 41 ccRCC patients before and after nephrectomy.
• Utilized ultra-performance liquid chromatography-high-resolution mass spectrometry (UPLC-HRMS).
• Compared lipid and metabolite fingerprints of ccRCC patients with healthy individuals.

Main Results:

• The 16-lipid panel differentiated metabolic phenotypes associated with post-surgery recovery.
• Identified a serum signature indicating a return to a healthy metabolic state.
• PC 16:0/0:0, PC 18:2/18:2, and linoleic acid distinguished ccRCC patients with poor versus improved prognosis.

Conclusions:

• The evaluated lipid panel shows potential as a prognostic tool for ccRCC.
• Ratios involving specific lipids may aid clinical decision-making in patient follow-up.
• Further validation in larger, diverse cohorts is necessary.
