LGALS7 and oral cavity squamous cell carcinoma: Another study performed on FFPE tissues from 18 patients with locally advanced oral squamous cell carcinoma (OSCC) treated with neoadjuvant radiotherapy identified and validated galectin 7 (LGALS7) as a predictor of RT resistance with high specificity and sensitivity, as suggested by 5-year disease-specific survival rates that significantly differed between low- and high-abundance groups of galectin-7 [141].
