...high levels of IL-8 and sICAM-1 at baseline were significantly associated with shorter OS [HR 2.69 (95%CI 1.28-5.92), p = 0.009; HR 3.50 (95%CI 1.63-8.16), p = 0.001, respectively]; whereas, comparable PFS....This study identified baseline plasma levels of IL-8 and sVCAM-1 as potential prognostic markers corresponding to favorable OS for combination therapy of PTX, RAM plus Nivo in patients with AGC. In addition, the increase in IL-6 level at 4 weeks may predict clinical benefit from the combination therapy.
