Peripheral blood absolute lymphocyte/monocyte ratio recovery during ABVD treatment cycles predicts clinical outcomes in classical Hodgkin lymphoma.

ABSTRACT: The peripheral blood absolute lymphocyte/monocyte count ratio at diagnosis (ALC/AMC-DX) predicts survival in classical Hodgkin lymphoma (cHL). However, a limitation of the ALC/AMC-DX is the inability to assess sequentially the host/tumor interaction during treatment. Therefore, we retrospectively examined the ALC/AMC ratio, as a surrogate marker of host immunity (ALC) and tumor microenvironment (AMC), at each adriamycin, bleomycin, vinblastine and dacarbazine treatment cycle as a predictor for clinical outcomes. From 1990 until 2008, 190 cHL patients were diagnosed, treated and followed at Mayo Clinic Rochester and qualified for the study. The ALC/AMC ratio at each treatment cycle was a predictor for overall survival (OS) and progression-free survival (PFS). An ALC/AMC ratio ?1.1 versus ALC/AMC <1.1 during treatment cycles was an independent predictor for OS (hazard ratio (HR)=0.14; 95% confidence interval (CI): 0.04-0.40; P<0.0002) and for PFS (HR=0.19; 95% CI: 0.05-0.82; P<0.03). The ALC/AMC ratio during treatment cycles is a predictor for survival and provides a platform to develop therapeutic modalities to manipulate the ALC/AMC ratio during chemotherapy to improve clinical outcomes in cHL.

Project description:BackgroundPrognoses of most adult Hodgkin lymphoma (HL) patients are excellent; most of them can achieve permanent remission that can be considered cured. However, many are under-treated or over-treated by standard modern therapies. An accurate determination of prognosis may allow clinicians to design personalised treatment according to individual risk of disease progression and survival. Lymphocyte monocyte ratio (LMR) at diagnosis has been investigated as a prognostic biomarker in patients with HL. Our objective with this meta-analysis was to explore the prognostic value of the LMR at diagnosis in adult HL, by investigating the association between LMR and survival outcomes.MethodsPUBMED and EMBASE were searched for relevant articles. Survival outcomes that we investigated included overall survival (OS), progression-free survival (PFS), event-free survival (EFS), lymphoma-specific survival (LSS), and time to progression (TTP). No restriction to the language, date, study country, or sample size was applied. Final search of databases was performed on 2 April 2018. We performed random-effects meta-analysis to aggregate and summarise the results from included studies, where four or more studies on a particular outcome were available.ResultsA total of eight studies (all retrospective cohort studies) involving 3319 HL patients were selected for analysis. All studies except one reported the effect of LMR on OS; five reported on PFS, three reported on TTP and LSS, respectively, and one reported on EFS. The pooled estimates showed low LMR was associated with poor OS (hazard ratio [HR] 2.67, 95% CI 1.67, 4.26) and PFS (HR 2.19, 95% CI 1.46, 3.29). Subgroup analyses of OS stratified by LMR cut-off values and sample sizes both indicated that low baseline LMR was associated with poorer prognosis.ConclusionsLow LMR at diagnosis was associated with poor OS and PFS in HL. LMR is easy and cheap to determine and has a potential role in daily clinical management. More studies are needed to validate this biomarker and explore its interaction with known prognostic factors.
