In contrast, although SAA immunoreactivity in tumor cells predicted a worse prognosis, there was no statistical significance in the univariate Cox proportional hazards regression analysis (OS: HR = 2.91, p = 0.203; RFS: HR = 3.06, p = 0.057) (Tables 3 and 4; Figure 2). The gene discussed is SAA1; the disease is neoplasm.
