CRP and neoplasm: The pre-treatment CRP level was significantly correlated with body mass index (BMI, p = 0.005) and initial tumor stage (T1/2 vs T3 vs T4, p < 0.001), and the involvement of the circumferential resection margin defined on the magnetic resonance imaging (mrCRM, p = 0.048); in addition, a significant association between the pre-treatment and post-treatment CRP level was observed (p < 0.001).
