Background and Aims.
Linked color imaging (LCI) helps screen and diagnose for early gastric cancer by color contrast in different mucosa.
RGB (red, green, and blue) pixel brightness quantifies colors, which is relatively objective.
Limited studies have combined LCI images with RGB to help screen for early gastric cancer (EGC).
We aimed to evaluate the RGB pixel brightness characteristics of EGC and noncancer areas in LCI images.
Methods.
We retrospectively reviewed early gastric cancer (EGC) patients and LCI images.
All pictures were evaluated by at least two endoscopic physicians.
RGB pixel brightness analysis of LCI images was performed in MATLAB software to compare the cancer with noncancer areas.
Receiver operating characteristic (ROC) curve was analyzed for sensitivity, specificity, cut-off, and area under the curve (AUC).
Results.
Overall, 38 early gastric cancer patients were enrolled with 38 LCI images.
Pixel brightness of red, green, and blue in cancer was remarkably higher than those in noncancer areas (190.24±37.10 vs.
160.00±40.35, p<0.001; 117.96±33.91 vs.
105.33±30.01, p=0.039; 114.36±34.88 vs.
90.93±30.14, p<0.001, respectively).
Helicobacter plyori (Hp) infection was not relevant to RGB distribution of EGC.
Whether the score of Kyoto Classification of Gastritis (KCG) is ≥4 or <4, the pixel brightness of red, green, and blue was not disturbed in both cancer and noncancer (p>0.05).
Receiver operating characteristic (ROC) curve for differentiating cancer from noncancer was calculated.
The maximum area under the curve (AUC) was 0.767 in B/G, with a sensitivity of 0.605, a specificity of 0.921, and a cut-off of 0.97.
Conclusions.
RGB pixel brightness was useful and more objective in distinguishing early gastric cancer for LCI images.
