Bottom Line: However, although MIC-1 correlated weakly with dietary intake (r(2)=0.157; P=0.031), it did not correlate with weight loss, BMI, or anthropometry.Patients with MIC-1 levels in the upper quartile showed reduced survival (median=204 days; 95% CI 157-251) when compared with patients with MIC-1 levels in the lower three quartiles (median=316 days; 95% CI 259-373; P=0.036), but MIC-1 was not an independent prognostic indicator.There is no independent link between plasma MIC-1 levels and depleted nutritional status or survival in OGC.

ABSTRACT

Background: Macrophage inhibitory cytokine-1(MIC-1) is a potential modulator of systemic inflammation and nutritional depletion, both of which are adverse prognostic factors in oesophago-gastric cancer (OGC).

Methods: Plasma MIC-1, systemic inflammation (defined as plasma C-reactive protein (CRP) of > or =10 mg l(-1) or modified Glasgow prognostic score (mGPS) of > or =1), and nutritional status were assessed in newly diagnosed OGC patients (n=293). Healthy volunteers (n=35) served as controls.

Results: MIC-1 was elevated in patients (median=1371 pg ml(-1); range 141-39 053) when compared with controls (median=377 pg ml(-1); range 141-3786; P<0.001). Patients with gastric tumours (median=1592 pg ml(-1); range 141-12 643) showed higher MIC-1 concentrations than patients with junctional (median=1337 pg ml(-1); range 383-39 053) and oesophageal tumours (median=1180 pg ml(-1); range 258-31 184; P=0.015). Patients showed a median weight loss of 6.4% (range 0.0-33.4%), and 42% of patients had an mGPS of > or =1 or plasma CRP of > or =10 mg l(-1) (median=9 mg l(-1); range 1-200). MIC-1 correlated positively with disease stage (r(2)=0.217; P<0.001), age (r(2)=0.332; P<0.001), CRP (r(2)=0.314; P<0.001), and mGPS (r(2)=0.336; P<0.001), and negatively with Karnofsky Performance Score (r(2)=-0.269; P<0.001). However, although MIC-1 correlated weakly with dietary intake (r(2)=0.157; P=0.031), it did not correlate with weight loss, BMI, or anthropometry. Patients with MIC-1 levels in the upper quartile showed reduced survival (median=204 days; 95% CI 157-251) when compared with patients with MIC-1 levels in the lower three quartiles (median=316 days; 95% CI 259-373; P=0.036), but MIC-1 was not an independent prognostic indicator.

Conclusions: There is no independent link between plasma MIC-1 levels and depleted nutritional status or survival in OGC.

Mentions: The relationship between MIC-1 and CRP was not linear, as dot-plots showed wide variance of CRP with increasing MIC-1 (Figure 6). However, assuming linearity, regression analysis showed that MIC-1 accounted for 5.9% of the variation in plasma CRP (P<0.001). In a regression model of CRP (incorporating MIC-1, disease stage, tumour grade, percentage weight loss, diet score and KPS, i.e., those factors found to correlate with CRP), plasma MIC-1 concentration (P=0.003), diet score (P=0.001), and tumour grade (P=0.033) were significant determinants (r2=0.179; Table 3). In a regression model of percentage weight loss (incorporating disease stage, mGPS, diet score, and dysphagia score), all four factors were significant determinants (r2=0.259; Table 3). Plasma MIC-1 concentration did not qualify to enter the model.
