Interleukin-6 and C-reactive protein as prognostic biomarkers in metastatic colorectal cancer.

ABSTRACT:

Objectives

The aim was to explore the prognostic significance of IL-6 and markers of systemic inflammatory response (SIR), in particular C-reactive protein (CRP), in metastatic colorectal cancer (mCRC) patients, in the total study population and according to RAS and BRAF mutation status.

Results

High levels of pretreatment serum IL-6 or CRP were associated with impaired outcome, in terms of reduced PFS and OS. Patients with low versus high serum IL-6 levels had median OS of 26.0 versus 16.6 months, respectively (P < 0.001). Stratified according to increasing CRP levels, median OS varied from 24.3 months to 12.3 months, (P < 0.001). IL-6 and CRP levels affected overall prognosis also in adjusted analyses. The effect of IL-6 was particularly pronounced in patients with BRAF mutation (interaction P = 0.004).

Materials and methods

IL-6 and CRP were determined in pre-treatment serum samples from 393 patients included in the NORDIC-VII trial, in which patients with mCRC received first line treatment. The effect of serum IL-6 and CRP on progression-free survival (PFS) and overall survival (OS) was estimated.

Conclusions

High baseline serum consentrations of IL-6 or CRP were associated with impaired prognosis in mCRC. IL-6 and CRP give independent prognostic information in addition to RAS and BRAF mutation status.

Project description:Background: Emerging evidence suggests that inflammatory response biomarkers are predictive factors that can improve the accuracy of colorectal cancer (CRC) prognoses. We aimed to evaluate the prognostic significance of C-reactive protein (CRP), the Glasgow Prognostic Score (GPS), and the CRP-to-albumin ratio (CAR) in CRC. Methods: Overall, 307 stage I-III CRC patients and 72 colorectal liver metastases (CRLM) patients were enrolled between October 2013 and September 2019. We investigated the correlation between the pretreatment CRP, GPS, and CAR and the clinicopathological characteristics. The Cox proportional hazards model was used for univariate or multivariate analysis to assess potential prognostic factors. A receiver operating characteristic (ROC) curve was constructed to evaluate the predictive value of each prognostic score. We established CRC survival nomograms based on the prognostic scores of inflammation. Results: The optimal cutoff levels for the CAR for overall survival (OS) in all CRC patients, stage I-III CRC patients, and CRLM patients were 0.16, 0.14, and 0.25, respectively. Kaplan-Meier analysis and log-rank tests demonstrated that patients with high CRP, CAR, and GPS had poorer OS in CRC, both in the cohorts of stage I-III patients and CRLM patients. In the different cohorts of CRC patients, the area under the ROC curve (AUC) of these three markers were all high. Multivariate analysis indicated that the location of the primary tumor, pathological differentiation, and pretreatment carcinoembryonic antigen (CEA), CRP, GPS, and CAR were independent prognostic factors for OS in stage I-III patients and that CRP, GPS, and CAR were independent prognostic factors for OS in CRLM patients. The predictors in the prediction nomograms included the pretreatment CRP, GPS, and CAR. Conclusions: CRP, GPS, and CAR have independent prognostic values in patients with CRC. Furthermore, the survival nomograms based on CRP, GPS, and CAR can provide more valuable clinical significance.

Project description:BackgroundThe application of regorafenib has changed the landscape of subsequent-line treatment in metastatic colorectal cancer (mCRC). Baseline neutrophil-to-lymphocyte ratio (NLR) and C-reactive protein (CRP), as two of the most common inflammatory factors, are suggested to be potential prognostic factors for mCRC patients treated with regorafenib, but the results are conflicting. In this study, we conducted a meta-analysis to evaluate the prognostic role of NLR and CRP in mCRC patients treated with regorafenib.MethodsWe searched online databases such as Embase, PubMed, and the Cochrane library up to April 2022, without language limitation, to identify clinical studies evaluating the prognostic role of NLR or CRP in regorafenib treated mCRC patients. The main endpoints were hazard ratio (HR) of overall survival (OS) and progression-free survival (PFS). The associations between NLR, CRP, and the above endpoints were extracted. Review Manager 5.4 was used to conduct the combined analysis. The Newcastle-Ottawa Scale (NOS) was applied for assessing the quality of included studies. Heterogeneity was detected by chi-square-based Q test and I2 statistic, and publication bias was evaluated by funnel plot asymmetry and Egger's test.ResultsEight studies involving 1,287 cases were included, with 5 reporting survival outcomes based on NLR level and 4 reporting survival according to CRP level. The results of meta-analysis showed that the calculated HR of OS for subsequent-line regorafenib in mCRC patients with high versus low NLR was 2.52 [I2=52%, 95% confidence interval (CI): 1.75-3.64; P<0.00001]. The combined HR of PFS with high versus low baseline NLR was 2.11 (I2=12%, 95% CI: 1.80-2.48; P<0.00001). For patients with a high level of CRP, the OS was significantly shorter when compared with patients with a low level of CRP (I2=0%, HR =1.88; 95% CI: 1.55-2.29; P<0.00001).ConclusionsHigh level of NLR could be associated with OS in mCRC patients treated with regorafenib. It is suggested that the impact of regorafenib on OS may vary according to the baseline NLR.
