Core Tip
Core Tip: This retrospective study investigates how the primary tumor location in colorectal cancer affects clinical outcomes following liver metastasis resection. Among 178 patients, right-sided colon cancers were associated with significantly higher recurrence rates, postoperative complications, and worse survival compared to left-sided and rectal cancers. Multivariate analysis identified right-sided origin, lymph node metastasis, elevated D-dimer, hypoalbuminemia, poor neoadjuvant response, and high clinical risk scores as independent predictors of recurrence. These findings highlight the prognostic importance of tumor site and support site-specific treatment strategies for patients with colorectal liver metastases to improve surgical safety and long-term outcomes.
