In comparison, stomatin-like protein 2, which shows a high degree of sequence similarity to stomatin, had been reported to be associated with a decreased overall survival among breast cancer [20], pulmonary squamous carcinoma [21], glioma [22], endometrial adenocarcinoma [23], laryngeal squamous carcinoma [24], esophageal squamous carcinoma [25] and colorectal cancer [26] patients. This evidence concerns the gene STOM and breast carcinoma.
