Abstract Background Stage IV colorectal cancer (CRC) patients are heterogeneous with distinctive clinicopathologic features and prognosis. Radical resection of primary tumor and distant metastases is associated with improved survival outcomes in metastatic CRC. The value of palliative primary tumor resection is controversial. The present study explored which subgroups benefited more from primary tumor resection in metastatic CRC. Methods Between 2004 and 2015, patients with metastatic CRC were identified using the surveillance, epidemiology, and end results (SEER) database. Uni- and multivariable Cox regression analysis were performed to identify factors associated with decreased cancer-specific mortality. The subgroups were divided based on the independent prognostic factors. Results Age, marital status, race, serum CEA, histologic type, differentiation, tumor location, surgery of primary or metastatic lesion, site of metastases, number of metastatic sites, chemotherapy and radiotherapy were identified as independent prognostic factors. Patients with non-white race, normal serum CEA, non-signet ring cell carcinoma, well or moderate differentiation, surgery of metastases, isolated liver metastasis, single metastasis, receiving chemotherapy or radiotherapy presented more survival benefit from primary tumor resection. Conclusion Subgroup of metastatic CRC optimizes decision-making and selected patients will benefit more from primary tumor resection.

The management of patients with colorectal cancer (CRC) and potentially resectable liver metastases (LM) requires quick assessment of mutational status and of response to pre-operative systemic therapy. In a prospective phase II trial (NCT01442935), we investigated the clinical validity of circulating tumor cell (CTC) and circulating tumor DNA (ctDNA) detection. CRC patients with potentially resectable LM were treated with first-line triplet or doublet chemotherapy combined with targeted therapy. CTC (Cellsearch®) and Kirsten RAt Sarcoma (KRAS) ctDNA (droplet digital polymerase chain reaction (PCR)) levels were assessed at inclusion, after 4 weeks of therapy and before LM surgery. 153 patients were enrolled. The proportion of patients with high CTC counts (≥3 CTC/7.5mL) decreased during therapy: 19% (25/132) at baseline, 3% (3/108) at week 4 and 0/57 before surgery. ctDNA detection sensitivity at baseline was 91% (N=42/46) and also decreased during treatment. Interestingly, persistently detectable KRAS ctDNA (p = 0.01) at 4 weeks was associated with a lower R0/R1 LM resection rate. Among patients who had a R0/R1 LM resection, those with detectable ctDNA levels before liver surgery had a shorter overall survival (p < 0.001). In CRC patients with limited metastatic spread, ctDNA could be used as liquid biopsy tool. Therefore, ctDNA detection could help to select patients eligible for LM resection.

e15078 Background: IL-6 and YKL-40, markers of inflammation and cancer growth, are high in serum in patients with colorectal cancer (CRC) and associated with shorter overall survival (OS). We hypothesized that preoperative serum IL-6, YKL-40 and CEA are associated with disease free survival (DFS) and OS in patients with metastatic (mCRC) treated with liver resection. Methods: 457 patients (male/female: 267 (58%)/190 (42%), median age 65 [IQR: 58-71]) diagnosed with mCRC who underwent liver resection were included between March 1998 and February 2013. Preoperative serum samples were collected and stored at -80°C until analysis. Serum IL-6 (R&D Systems, UK) and YKL-40 (Quidel, USA) were determined by ELISA. For DFS and OS we estimated crude and adjusted hazard ratios (HR) and corresponding 95% confidence intervals (CIs) with Cox regression for each biomarker separately. The biomarkers were included as log2-transformed continuous variables and adjustment included mutual adjustment between the biomarkers in addition to adjusting for sex and age. Results: The median (IQR) preoperative biomarker levels were: IL-6 (3.5 pg/ml, 2.1-6.1), YKL-40 (75 ng/ml, 48-127) and CEA (5.2 kU/L, 2.6-18.8). Univariate analysis showed that high serum IL-6 and YKL-40 were associated with shorter DFS (IL-6: HR = 1.18, 1.06-1.31, p < 0.01; YKL-40: HR = 1.19, 1.08-1.32, p < 0.01). Serum CEA was not (p = 0.80). Multivariate analysis (all biomarkers) showed that high IL-6 was associated with shorter DFS (HR = 1.15, 1.02-1.29, p = 0.02), whereas YKL-40 (p = 0.08) and CEA (p = 0.51) were not. Univariate analysis showed that high preoperative serum IL-6 and YKL-40 were associated with shorter OS (IL-6: HR = 1.16, 1.03-1.29, p = 0.01; YKL-40: HR = 1.27, 1.14-1.42, p < 0.01). Serum CEA was not associated with OS (p = 0.16). Multivariate analysis (all biomarkers) showed that high YKL-40 was associated with shorter OS (HR = 1.19, 1.05-1.34, p = 0.01), whereas IL-6 (p = 0.25) and CEA (p = 0.26) were not. Patients with elevated serum levels of all 3 biomarkers had the shortest OS (HR = 2.12; 1.29-3.50, p < 0.01). Conclusions: Serum IL-6 and YKL-40 determined before liver resection may be valuable prognostic biomarkers in patients with metastatic CRC.

First-line treatment of metastatic colorectal cancer with combinations of cetuximab and irinotecan-based or oxaliplatin-based chemotherapy has shown promising efficacy. The clinical response to such treatment is generally assessed by tumor measurement through imaging. This study was performed to evaluate the correlation between serial changes in imaging results and carcinoembryonic antigen (CEA) levels. In 64 patients with metastatic colorectal cancer receiving cetuximab plus FOLFIRI or FOLFOX-4 chemotherapy we retrospectively analyzed the relationship between changes in serum CEA and changes in imaging results throughout the treatment course. Response in terms of serum CEA change was defined as a ≥50% drop in CEA level for more than 4 weeks. The sensitivity and specificity of serum CEA changes after targeted chemotherapy in relation to imaging results were 80.5% (33/41) and 73.9% (17/23), respectively, with a diagnostic accuracy of 78.1% (50/64). The progression-free survival time of responders assessed by serum CEA change was significantly longer than that of nonresponders (p=0.0091). Our results highlight the importance of serum CEA monitoring in assessing the response to targeted chemotherapy and in predicting the prognosis of patients with metastatic colorectal cancer.
