Kaplan-Meier survival plots; (A) Serum albumin level ≥3.9 g/dL was shown to be a significant predictor of progression free survival (PFS) (HR=0.243, 95% CI 0.086–0.691, P=0.004); (B) PLR was also significantly prognostic for PFS when evaluated for values of <95 (HR=0.298, 95% CI 0.114–0.779, P=0.009); (C) IPI, when categorized by a score of 1 versus 2–4, had prognostic significance for PFS (HR=0.444, 95% CI 0.211–0.933, P=0.017).
