The Δ133p53 β-variant has recently been linked to increased tumor invasiveness and worse prognosis in a cohort of breast cancers [17], but higher Δ133p53 levels have also been linked to favorable prognosis in TP53 mutant advanced ovarian cancer [19] No such clinical associations of Δ133p53 expression were observed in our cohort. Here, TP53 is linked to breast carcinoma.
