Clinical Report: Uncommon Progression of BRAF/KRAS Wild-Type Colorectal Cancer
Overview
This report details a rare case of cerebral metastasis in a patient with BRAF/KRAS wild-type colorectal cancer, highlighting the potential for delayed CNS dissemination despite apparent systemic remission. The findings challenge existing assumptions about CNS risk stratification in colorectal cancer.
Background
Incorporate specific statistics or references to support the low-risk profile claims.
Data Highlights
No numerical data or trial data provided in the article.
Key Findings
A 66-year-old woman with sigmoid colon adenocarcinoma developed brain metastases over a year after completing systemic therapy.
The tumor was microsatellite-stable, with low tumor mutational burden and wild-type KRAS/NRAS/BRAF.
Despite achieving systemic remission, the patient exhibited delayed CNS metastasis, challenging current risk stratification assumptions.
Histopathology confirmed the brain lesions as metastatic adenocarcinoma of colorectal origin.
This case raises questions about the necessity for individualized neurological surveillance in selected patient subgroups.
Clinical Implications
Clinicians should be aware that even patients with low-risk molecular profiles for colorectal cancer may still develop CNS metastases. This case suggests the need for more vigilant neurological monitoring in certain patients, even after achieving systemic remission.
Conclusion
The occurrence of cerebral metastasis in a patient with wild-type KRAS/BRAF colorectal cancer highlights the complexity of disease progression and the need for tailored surveillance strategies.
