Galectin-7 as a potential predictive marker of chemo- and/or radio-therapy resistance in oral squamous cell carcinoma.
Bottom Line: Treatment of advanced oral squamous cell carcinoma (OSCC) requires the integration of multimodal approaches.The cumulative 5-year disease-specific survival rate was 75.2% in patients with resistant prediction using G7PS and 100% in patients with sensitive prediction.In vitro overexpression of galectin-7 significantly decreased cell viability in OSCC cell line.

Mentions: The protein expression of galectin-7 in OSCC tissue was confirmed by IHC analysis of the FFPE samples used for LC-MS analysis (Fig. 2A). Pearson's correlation analysis was conducted between G7S and each of the peaks listed in Table 2. A significant positive correlation was detected between G7S and the intensity of the two galectin-7 peaks, namely ID599 (r = 0.71; P = 0.001; Fig. 3A) and ID1181 (r = 0.73; P = 0.001; Fig. 3B). Scatter plot analysis was conducted for the G7S values of Group R and Group S (Fig. 4A). The median G7S was significantly lower for Group R (0.455) than for Group S (0.666; Mann–Whitney U-test; P = 0.003), suggesting that oral SSC patients with low galectin-7 expression are more likely to exhibit chemotherapy and/or radiotherapy resistance. The sensitivity of this prediction was 88.9% and specificity was 88.9% (cutoff point: 0.526).
