SQSTM1 and neoplasm: In multivariable analysis (using a model that included p62, age, sex, tumor stage, lymph mode metastasis, differentiation, and adjuvant therapy), p62 expression level was not found to be an independent prognostic factor for DSS (2-year and 5-year DSS, p62 high vs p62 low: p = 0.125 and p = 0.129, respectively).
