EEF1A2 and pancreatic ductal adenocarcinoma: In this regard, eEF1A2 expression in other tumor entities showed differing results: some studies attributed a higher expression of eEF1A2 with a poor prognosis (pancreatic ductal adenocarcinoma [60] and localized prostate cancer [66]), while others found that it was associated with a favorable outcome (non-small cell lung cancer [67] and breast cancer [38]).
