Abstract

The aim of this study was to determine the prognostic effect of the absolute neutrophil count/absolute lymphocyte count ratio (ANC/ALC ratio) in patients with classic Hodgkin lymphoma (cHL). We performed a retrospective analysis of 312 patients with cHL. Univariate analysis revealed that a high ANC/ALC ratio (≥4.3) correlated with poor overall survival (OS) (P < .001). Subgroup analysis of advanced-stage disease showed that the ANC/ALC ratio was significant for OS (P = .032). Multivariate analysis revealed the ANC/ALC ratio to be an independent prognostic factor for OS (P = .048). The ANC/ALC ratio allowed further risk stratification in patients who were considered to be at low risk on the basis of an International Prognostic Score less than 4 (P = .002). The ANC/ALC ratio is a simple, inexpensive, and independent prognostic factor for OS that may improve the ability to identify high-risk patients with cHL.

Key Words:
  • Hodgkin lymphoma
  • Neutrophil
  • Lymphocyte
  • Neutrophil/lymphocyte ratio
  • Prognosis

Upon completion of this activity you will be able to:

  • predict prognosis in patients with classic Hodgkin lymphoma using the ratio of absolute neutrophil count to absolute lymphocyte count (ANC/ALC).

  • differentiate a high-risk group among patients who are considered to be at low risk on the basis of an International Prognostic Score <4 using the ANC/ALC ratio.

  • recognize the effect of the ANC/ALC ratio in combination with the ALC to absolute monocyte count ratio for survival prediction of classic Hodgkin lymphoma.
