Serum lactate dehydrogenase is associated with the presence and extent of preoperative peritumoral edema in melanoma brain metastases
To investigate the association between preoperative serum lactate dehydrogenase (LDH) levels and the presence and volumetric extent of peritumoral brain edema (PTBE) in patients with melanoma brain metastases.
Approach:
Study Population: This retrospective study included consecutive patients who underwent surgical resection of melanoma brain metastases at the University Medical Center Leipzig from 2012 to 2024, following standardized perioperative care protocols.
Radiological Assessment: Preoperative MRI was reviewed to assess tumor characteristics and PTBE, with volumetric analysis performed using 3D Slicer software.
Clinical Variables and Laboratory Parameters: Clinical data and preoperative LDH levels were collected from medical records, with LDH measured as part of routine preoperative diagnostics.
Key Findings:
Elevated serum LDH levels are associated with increased tumor burden and aggressive disease behavior.
The relationship between LDH levels and PTBE has not been well understood previously.
Interpretation:
Identifying LDH as a potential biomarker for PTBE could aid in individualized perioperative risk stratification for patients with melanoma brain metastases.
Limitations:
The study is retrospective and may be subject to selection bias.
The analysis relies on preoperative imaging, which may not capture all relevant clinical variables.
Conclusion:
The study explores the utility of serum LDH as a preoperative biomarker for PTBE in melanoma brain metastases.
