Abstract

Background

Although patients with metastatic colorectal cancer (CRC) are often unable to undergo treatment after resection of primary tumors, identifying such patients before surgery is not easy. In this study, we evaluated the association among clinicopathological findings, survival outcomes, and ability to undergo multimodal therapy after primary tumor resection in patients with Stage IV CRC.

Methods

We collected clinicopathological findings and preoperative laboratory data, including carcinoembryonic antigen (CEA) and systemic inflammatory response markers for 92 patients who were treated for Stage IV CRC between 2005 and 2014. We used multivariate analysis on factors that affect prognosis and ability to undergo postoperative treatment.

Results

Postoperative multimodal therapy improved overall survival (OS) significantly. Among serum markers, elevated CEA, neutrophil-to-lymphocyte ratio, and modified Glasgow prognosis score (mGPS) were significant indicators of shorter OS. In multivariate analysis, low performance status (P = 0.003), undifferentiated histology type (P = 0.019), and elevated mGPS (P = 0.042) were independent predictors of worse prognosis; and older age (P = 0.016), right-sided colon cancer (P = 0.043), and elevated mGPS (P = 0.031) were independent risk factors for difficulty of introducing postoperative multimodal therapy.

Conclusions

Preoperative mGPS is a useful objective indicator for CRC patients with multiple metastases who are able to undergo primary site resection followed by postoperative multimodal therapy.

Supplemental Figure 1 Modified GPS score against histological differentiation. The mGPS2 group had a significantly higher percentage of poorly differentiated histological type (7/20, 35%) than the mGPS0/1 group (6/72, 8.3%, P = 0.0054). Supplemental Figure 2 Histological differentiation against NLR values. The poor histology group had significantly higher median preoperative NLR (5.53, range 0.96–17.71) than the well/moderate histology group (2.98, range 0.57–30.13; P = 0.0332). Supplemental Figure 3 Patient age in relation to whether or not they underwent postoperative treatment. Median age in the untreated group (75 years; range 59–90 years) was significantly older than in the treated group (63 years, range 31–84 years; P = 0.0002) (PPT 194 kb)
