For a poor prognosis of RFS, having a larger tumor size (≤5.5 vs >5.5 cm, P = 0.001), a high tumor stage (stage I/II vs III/IV, P = 0.025), nodal metastasis (absent vs no presence, P = 0.016), vascular invasion (absent vs presence, P = 0.003), postoperative chemotherapy (chemotherapy vs on postoperative treatment, P < 0.001), and a high serum CRP level (≤1.8 vs >1.8 mg/L, P < 0.001) were identified as poor prognostic factors. Here, CRP is linked to neoplasm.
