Low lymphocyte-to-monocyte ratio predicts poor outcome in high-risk aggressive large B-cell lymphoma. EJHAEM 2022; 3:681-687. [PMID: 36051040 PMCID: PMC9421995 DOI: 10.1002/jha2.409] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 01/04/2022] [Revised: 02/17/2022] [Accepted: 02/21/2022] [Indexed: 11/12/2022]
Abstract
Low lymphocyte-to-monocyte-ratio (LMR) has been associated with unfavorable survival in patients with diffuse large B-cell lymphoma (DLBCL). To date, however, the impact of LMR on survival has not been examined in a uniformly treated cohort of patients with high-risk aggressive large B-cell lymphoma. We collected peripheral blood absolute lymphocyte counts (ALCs) and absolute monocyte counts (AMC) prior to treatment and calculated LMR from 112 adult patients, who were less than 65 years of age, had age-adjusted International Prognostic Index 2-3, or site-specific risk factors for central nervous system (CNS) recurrence, and were treated in a Nordic Lymphoma Group LBC-05 trial with dose-dense immunochemotherapy and early systemic CNS prophylaxis (www.ClinicalTrials.gov, number NCT01325194). Median pretreatment ALC was 1.40 × 109/l (range, 0.20-4.95), AMC 0.68 × 109/l (range, 0.10-2.62), and LMR 2.08 (range, 0.10-12.00). ALC did not correlate with tumor-infiltrating lymphocytes, AMC did not correlate with tumor-associated macrophages, and neither ALC nor AMC correlated with survival. However, low LMR (<1.72) translated to unfavourable progression-free survival (PFS) (5-year PFS 70% vs. 92%, p = 0.002) and overall survival (OS) (5-year OS, 77% vs. 92%, p = 0.020). In the patients with low LMR, relative risk of progression was 4.4-fold (95% confidence interval [CI] 1.60-12.14, p = 0.004), and relative risk of death was 3.3-fold (95% CI 1.18-9.50, p = 0.024) in comparison to the patients with high LMR. We conclude that low LMR is an adverse prognostic factor in uniformly treated young patients with high-risk aggressive large B-cell lymphoma.

Prognostic values of geriatric nutritional risk index (GNRI) and prognostic nutritional index (PNI) in elderly patients with Diffuse Large B-Cell Lymphoma. J Cancer 2021; 12:7010-7017. [PMID: 34729103 PMCID: PMC8558670 DOI: 10.7150/jca.62340] [Citation(s) in RCA: 16] [Impact Index Per Article: 5.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/05/2021] [Accepted: 10/01/2021] [Indexed: 12/12/2022] Open
Abstract
Background: Geriatric nutritional risk index (GNRI) and prognostic nutritional index (PNI) are associated with prognosis of various malignancies. Although GNRI and PNI indicates prognosis in some clinical settings, the values of GNRI and PNI on the prognosis of geriatric patients with Diffuse Large B‐Cell Lymphoma (DLBCL) is unclear. This retrospective analysis aimed to explore the prognostic values of GNRI and PNI in elderly DLBCL patients. Methods: A total of 133 geriatric patients with DLBCL were recruited from Affiliated Hospital of Xuzhou Medical University, and clinicopathological variables were analyzed. X-Tile program, restricted cubic spline (RCS) and time-dependent receiver operating characteristic (ROC) analysis were used to determine optimal cut-off points of GNRI, PNI and other continuous variables; univariate and multivariate Cox proportional hazards analyses were used for variables selection; Kaplan‐Meier curve was utilized to analyze the influence of variables on prognosis; log-rank test was performed for difference evaluation between groups. Results: The optimal cut-off points for GNRI and PNI were 106.26 and 47 by using RCS. Multivariate analysis showed that PNI, age, hemoglobin, liver invasion and central nervous system invasion were independent prognostic factors for elderly patients with DLBCL, and PNI was (P = 0.001, HR = 0.413, 95% CI (0.240-0.710) a stronger predictor. Low PNI could predict worse prognosis independently of elderly patients of DLBCL and could re-stratify patients in GCB group, CD5 positive group BCL-2 positive group, and BCL-6 positive group. Conclusions: PNI was an independent adverse factor for elderly DLBCL and patients with low PNI in GCB group, CD5 positive group and BCL-6 positive group were with poor survival.

Prognostic Impact of Peripheral Blood T-Cell Subsets at the Time of Diagnosis on Survival in Patients with Diffuse Large B-Cell Lymphoma. Acta Haematol 2020; 144:427-437. [PMID: 33271543 DOI: 10.1159/000510912] [Citation(s) in RCA: 6] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/12/2019] [Accepted: 08/14/2020] [Indexed: 11/19/2022]
Abstract
INTRODUCTION The effects of lymphocyte subtypes, including helper (Th), natural killer (NK), and regulatory (Treg) cells, and other T-cell subtypes on treatment outcomes in diffuse large B-cell lymphoma (DLBCL) patients are not clearly established. METHODS Among 151 consecutive patients diagnosed with DLBCL, we collected peripheral blood samples at diagnosis from 91 patients who received at least 1 cycle of R-CHOP (cyclophosphamide, doxorubicin, vincristine, and prednisone plus rituximab) chemotherapy and analyzed lymphocyte subsets by flow cytometry. RESULTS DLBCL patients had a higher proportion of CD4+CD25+ Treg (p < 0.001) and lower absolute lymphocyte count than those of healthy controls. Lymphopenia at diagnosis was associated with advanced-stage disease (p = 0.001), a high-intermediate/high-risk International Prognostic Index (IPI) (p < 0.001), and older age (p = 0.060). High-intermediate/high-risk IPI, high proportion of CD3+CD4+ Th cells, and extranodal site ≥2 correlated with unfavorable prognostic factors for survival. High proportion of Th cells was associated with fewer cytotoxic T cells and NK cells at the time of diagnosis. CONCLUSION This study showed an association between circulating lymphocyte subsets including Th cells, Tregs, and NK cells and clinical outcomes in DLBCL; however, further confirmation is needed via prospective trials.

Validation and comparison of prognostic values of GNRI, PNI, and CONUT in newly diagnosed diffuse large B cell lymphoma. Ann Hematol 2020; 99:2859-2868. [PMID: 32970194 DOI: 10.1007/s00277-020-04262-5] [Citation(s) in RCA: 28] [Impact Index Per Article: 7.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/09/2020] [Accepted: 09/07/2020] [Indexed: 01/06/2023]
Abstract
Diffuse large B cell lymphoma (DLBCL) is the most common type of aggressive non-Hodgkin lymphoma. Emerging evidence indicates that poor nutritional status determined with nutritional indices such as geriatric nutritional risk index (GNRI), prognostic nutritional index (PNI), and controlling nutritional status score (CONUT) was associated with poor prognosis of DLBCL. We conducted this multicenter retrospective study to validate and compare prognostic values of the three indices in 615 newly diagnosed DLBCL patients. The overall survival (OS) in patients with poor nutritional status determined with each of these nutritional indices were significantly inferior compared with that in those without nutritional risks (5-year OS in patients with GNRI < 95.7 and GNRI ≥ 95.7 were 56.4% and 83.5%, P < 0.001; PNI < 42.4 and PNI ≥ 42.4 were 56.1% and 81.0%, P < 0.001; CONUT > 4 and CONUT ≤ 4 were 53.1% and 77.1%, P < 0.001). GNRI and CONUT were independent prognostic predictors for OS (GNRI < 95.7, hazard ratio [HR] 1.83, 95% confidence interval [CI] 1.22-2.74, P = 0.0032; CONUT > 4, HR 1.53, 95% CI 1.05-2.23, P = 0.028) after multivariate analyses. Nutritional status determined with GNRI affected OS more strongly in the patients with nongerminal center B cell-like (nonGCB) DLBCL compared with that in those with GCB-type DLBCL. In conclusion, baseline poor nutritional status determined based on GNRI or CONUT was an independent risk factor of newly diagnosed DLBCL, and GNRI was also useful as an independent prognostic factor for patients with nonGCB-type DLBCL.

Hepatitis B Surface Antigen Positivity Is an Independent Unfavorable Prognostic Factor in Diffuse Large B-Cell Lymphoma in the Rituximab Era. Oncologist 2020; 25:793-802. [PMID: 32275807 DOI: 10.1634/theoncologist.2019-0756] [Citation(s) in RCA: 7] [Impact Index Per Article: 1.8] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/04/2019] [Accepted: 03/25/2020] [Indexed: 12/24/2022] Open
Abstract
BACKGROUND Patients with diffuse large B-cell lymphoma (DLBCL) with concurrent hepatitis B surface antigen (HBsAg)-positive hepatitis B virus (HBV) infection have distinct clinical features. Nevertheless, the prognostic value of HBsAg in DLBCL in the rituximab era remains unclear. MATERIALS AND METHODS We conducted a retrospective cohort study to investigate the clinical relevance of HBsAg in immunocompetent patients with DLBCL treated with homogeneous rituximab plus cyclophosphamide, doxorubicin, vincristine, and prednisone between 2002 and 2016. RESULTS Among 416 analyzed patients, 98 (23.6%) were HBsAg positive. HBsAg positivity was associated with a younger age and more advanced stage at diagnosis, more frequent hepatic impairment during perichemotherapy, and a trend of higher National Comprehensive Cancer Network-International Prognostic Index (NCCN-IPI) score at diagnosis. Compared with the HBsAg-negative patients, the HBsAg-positive patients had a lower overall response rate (76.5% vs. 85.5%, p = .043), poorer 5-year overall survival (OS) rate (57.2% vs. 73.5%, p < .001), and shorter 5-year progression-free survival (PFS) rate (47.2% vs. 60.7%, p = .013). Multivariate analyses showed that HBsAg positivity was an independent unfavorable prognostic indicator for OS and PFS. A scoring system incorporating HBsAg positivity, the NCCN-IPI score, and serum albumin levels proved to be useful for stratifying prognostically relevant subgroups of patients with DLBCL. CONCLUSION This study demonstrated that HBV infection is uniquely relevant to DLBCL. HBsAg might serve as a novel biomarker to improve clinical risk stratification of patients with DLBCL in areas with high prevalence of HBV infection. Further research investigating the etiopathogenesis of HBV infection in DLBCL is imperative. IMPLICATIONS FOR PRACTICE A considerable disparity exists regarding the prognostic relevance of hepatitis B surface antigen (HBsAg)-positive hepatitis B virus (HBV) infection in patients with diffuse large B-cell lymphoma (DLBCL). In this large, retrospective cohort study from an area with high prevalence of HBV infection, the authors demonstrated that HBsAg was an independent unfavorable factor significantly associated with survival, highlighting its potential as a novel prognostic indicator to improve the risk stratification of patients with DLBCL in the rituximab era.

New prognosis score including absolute lymphocyte/monocyte ratio, red blood cell distribution width and beta-2 microglobulin in patients with diffuse large B-cell lymphoma treated with R-CHOP: Spanish Lymphoma Group Experience (GELTAMO). Br J Haematol 2019; 188:888-897.

Abstract
The International Prognostic Index (IPI) is the most widely used score for non-Hodgkin lymphoma but lacks the ability to identify a high-risk population in diffuse large B-cell lymphoma (DLBCL). Low absolute lymphocyte count and high monocytes have proved to be unfavourable factors. Red-cell distribution width (RDW) has been associated with inflammation and beta-2 microglobulin (B2M) with tumour load. The retrospective study included 992 patients with DLBCL treated with R-CHOP. In the multivariate analysis, age, Eastern Cooperative Oncology Group performance status (ECOG-PS), stage, bulky mass, B2M, RDW, and lymphocyte/monocyte ratio (LMR) were independently related to progression-free survival (PFS). A new prognosis score was generated with these variables including age categorized into three groups (0, 1, 2 points); ECOG ≥ 3-4 with two; stage III/IV, bulky mass, high B2M, LMR < 2·25 and RDW > 0·96 with one each; for a maximum of 9. This score could improve the discrimination of a very high-risk subgroup with five-year PFS and overall survival (OS) of 19% and 24% versus 45% and 59% of R (revised)-IPI respectively. This score also showed greater predictive ability than IPI. A new score is presented including complete blood cell count variables and B2M, which are readily available in real-life practice without additional tests. Compared to R-IPI, it shows a more precise high-risk assessment and risk discrimination for both PFS and OS.

Abstract
In solid tumors and lymphomas, the neutrophil/lymphocyte (N/L) ratio at diagnosis has been shown to be a prognostic factor. The aim of our study was to validate the originally reported N/L ratio cut-point of 3.5 in patients with diffuse large B-cell lymphoma (DLBCL) registered in an Italian real-life database. The prognostic role of the N/L ratio at diagnosis on event-free survival (EFS) and overall survival (OS) was assessed in 505 patients with DLBCL. Patients with an N/L ratio <3.5 (n = 249) had a 4-year EFS probability of 76% and OS probability of 86%, significantly higher than the 4 year EFS rate of 48% and OS rate of 64% in patients with N/L ratio ≥3.5 (n = 256, both p<.0001). The N/L ratio was an independent prognostic factor in the multivariate analysis including the IPI score, and could separate patients with a low/intermediate risk IPI (IPI <3).

Abstract
BACKGROUND Recent studies have suggested that variables related to host adaptive immunity and the tumor microenvironment may predict the outcome in patients with non-Hodgkin's lymphoma. This study was undertaken to determine the prognostic value of peripheral blood leucocyte subpopulations in diffuse large-B-cell lymphoma patients. METHODS We prospectively analyzed the 16 leukocyte subpopulations using Cytodiff flow cytometric technique in a cohort of 45 diffuse large-B-cell lymphoma patients at a single institution between February and December 2014. The Cox proportional hazards model was used to evaluate prognostic factors for overall survival and progression free survival. RESULTS Diffuse large-B-cell lymphoma patients had decreased cytotoxic and non-cytotoxic NK&T cells as well as increased CD16+ monocytes, CD16- monocytes and mature neutrophils. The decreased CD16- monocyte/CD16+ monocyte ratio and increased mature neutrophil/cytotoxic NK&T cell ratio were related to poor progression-free and overall survival outcome in single and multivariate analysis. The co-constructed model using International Prognostic Index and mature neutrophil/cytotoxic NK&T cell ratio can also help discriminate the clinical outcome. CONCLUSIONS The decreased CD16-monocyte/CD16+monocyte ratio and increased mature neutrophil/cytotoxic NK&T cell ratio predict poor prognosis in diffuse large-B-cell lymphoma patients. This finding provides a strong rationale for the study of cellular immunotherapy in B-cell lymphoma.

Abstract
BACKGROUND Pretreatment neutrophil-to-lymphocyte ratio (NLR) and absolute lymphocyte count (ALC) recovery have been shown to be associated with prognosis in several types of cancer in adults. However, evidence in pediatric cancer is scarce. The aim of our study was to evaluate whether pretreatment NLR and lymphocyte recovery are prognostic factors in pediatric sarcomas. MATERIALS AND METHODS Study participants were identified from a retrospective cohort of 100 children with osteosarcoma (n=55), rhabdomyosarcoma (n=22), and Ewing sarcoma (n=23). Data for the hematological variables were obtained from medical records and analyzed with other known prognostic factors in univariate and multivariate analyses. RESULTS In multivariate analysis, NLR>2 was an independent prognostic factor for OS in patients with osteosarcoma (hazard ratio [HR], 2.27, 95% confidence interval [CI], 1.07-5.30; P=0.046) along with metastatic disease and poor histologic response; as well as in patients with rhabdomyosarcoma (HR, 4.76, 95% CI, 1.01-22.24; P=0.0237) along with metastatic disease and risk group. ALC recovery correlated for inferior OS in osteosarcoma (HR, 3.34, 95% CI, 1.37-8.12; P=0.008) and rhabdomyosarcoma (HR, 3.89; 95% CI, 1.01-14.89; P=0.0338). CONCLUSIONS Our study confirms that NLR and ALC recovery are independent prognostic factors for pediatric sarcomas, implying an important role of immune system in survival. Clinical utility of these prognostic biomarkers should be validated in larger pediatric studies.

Serum level of CXCL10 is associated with inflammatory prognostic biomarkers in patients with diffuse large B-cell lymphoma. Hematol Oncol 2016; 35:480-486.

Abstract
Inflammatory biomarkers, such as the neutrophil to lymphocyte ratio (NLR), lymphocyte to monocyte ratio (LMR), and Glasgow Prognostic Score (GPS) have been proposed to predict prognosis in diffuse large B-cell lymphoma (DLBCL). C-X-C motif ligand 10 (CXCL10) is a chemokine released from inflammatory cells in the tumor microenvironment and is known to promote tumor cell migration and invasion. In this study, we investigated the clinical impact of pretreatment serum level of CXCL10 on the prognostic value of inflammatory biomarkers in 313 patients with DLBCL who were enrolled into a prospective cohort study. Serum level of CXCL10 was measured in archived pretreatment frozen samples. The high CXCL10 (>median value) group was significantly associated with high tumor burden status, including advanced stage (III-IV), elevated serum lactic dehydrogenase, and a higher risk International Prognostic Index. Progression-free survival of the high CXCL10 group was significantly worse than that of the low CXCL10 group, and secondary central nervous system involvement was more frequent in the high CXCL10 group. High CXCL10 was associated with high C-reactive protein level (r = 0.246), low albumin level (r = -0.289), low absolute lymphocyte count (r = -0.185), and risk stratification according to NLR, LMR, and GPS. C-X-C motif ligand 10 promoted cell migration of patient-derived cells and several DLBCL cell lines. However, the prognostic value of high CXCL10 was lost in the multivariate analyses. Nevertheless, we suggest serum CXCL10 may have clinical value if it can be more easily assessed because of its contribution to the prognostic value of NLR, LMR, and GPS in DLBCL.

Abstract
BACKGROUND We evaluated the prognostic significance of neutrophil/lymphocyte ratio (NLR) and platelet/lymphocyte ratio (PLR) in patients with multiple myeloma (MM). METHODS In total, we retrospectively analyzed 315 newly diagnosed MM patients and calculated NLR and PLR from the complete blood count of the untreated patients. We further assessed the role of pretreatment NLR and PLR on overall survival (OS) and progression-free survival (PFS). RESULTS Multiple myeloma patients with high NLR (≥2) experienced shorter OS (P=.02) and PFS (P=.01) compared with patients with low NLR (<2). Furthermore, among the patients with conventional chemotherapy, elderly patients, or patients with advanced stages, high NLR (≥2) was found to have a negative prognostic impact on OS and PFS. In the multivariate Cox analysis, we confirmed that the NLR was an independent prognostic factor for both OS and PFS (P=.000). But the differences in OS or PFS by PLR were not found in MM patients. CONCLUSIONS Our study suggests that NLR not PLR can be acted as an independent prognostic factor for analyzing the clinical outcome of MM patients.

Abstract
BACKGROUND Tumor-infiltrating immune cells influence diffuse large B-cell lymphoma (DLBCL) outcomes. Relatively little, however, is known about the significance of peripheral blood immune cell numbers on DLBCL behavior. PATIENTS AND METHODS In the present study, 43 patients with newly diagnosed DLBCL had pretreatment multiparameter peripheral blood flow cytometry performed to assess the immune cell numbers. These cell numbers were correlated with the outcomes of progression-free survival (PFS) and overall survival. RESULTS After follow-up period of 0.8 to 152 months (median, 73), 25 patients (56%) were still alive. As continuous variables on univariate analysis, the predictors of PFS were patient age and absolute CD4 cell count (ACD4C), with the International Prognostic Index (IPI) marginally significant. Age was also a significant predictor of overall survival, and the IPI and ACD4C were marginally significant (P = .08). The 17 patients with a greater ACD4C (≥ 450/mm3) had better 5-year PFS than the 26 with a low ACD4C (88% vs. 50%; P = .02). Multivariable analysis, including age as a continuous variable, IPI group, and ACD4C of 450/mm3 showed that age and ACD4C were significant for PFS (P = .01 and P = .02, respectively). CONCLUSION Our data, although from a small series, suggest that the blood ACD4C might be a predictor of PFS for patients with DLBCL, independent of age and the IPI.

Abstract
The Follicular Lymphoma International Prognostic Index (FLIPI) is widely used in the identification of risk groups among follicular lymphoma (FL) patients. The aim of the present study was to evaluate the prognostic value of FLIPI combined with the Charlson comorbidity index (CCI) and histological grade of lymphoma. 224 newly diagnosed FL patients (median age 56 years) treated with immunochemotherapy were retrospectively analysed. Low FLIPI had 21.0 % of patients, intermediate 28.1 % and high 46.9 %. 50.9 % of patients had no comorbidities. Only 7.1 % of patients had a high CCI score (≥2), while 25.9 % of patients were histological grade 3. Parameters that influenced overall survival were evaluated using Cox regression analysis, in which CCI, FLIPI and histological grade (p < 0.05) retained prognostic significance. By combining these parameters, we have developed the FCG score, which incorporates FLIPI, CCI, and histological grade. This score defines three risk categories (low: 41.5 %; intermediate: 37.5 %; high: 13.4 %), associated with significantly different survival (p < 0.0001); this consequently improves discriminative power by 9.1 % compared to FLIPI. FCG score represents a possible new prognostic index, highlighting the role of the patient's clinical state and the histological characteristics of disease, as indicated by comorbidity index and histological grade of lymphoma.

Abstract
Aim To determine the prognostic value of baseline red blood cell distribution width (RDW) in diffuse large B cell lymphoma (DLBCL) patients. Methods Data from 81 DLBCL patients diagnosed from 2006 to 2013 at the University Hospital Center Osijek, Osijek, Croatia, were reviewed. We evaluated disease outcome, overall survival (OS) and event-free survival (EFS), and demographic, clinical and laboratory factors affecting outcome. Univariate analysis and Cox regression analysis were used. Results Median age of patients was 64 years, 29 were men (35.8%). Higher RDW levels (%) were found in patients with advanced Ann Arbor clinical stage (14.94 ± 1.82 vs 13.55 ± 1.54, P = 0.001) and in those with poor response to therapy (14.94 ± 1.82 vs 13.55 ± 1.54, P = 0.001). Patients with RDW>15% (cut-off was calculated by receiver operating characteristics) had significantly worse OS (median [range], 33 months [20-46] vs 74 months [65-82], P < 0.001) and EFS (27 months [15-40] vs 68 months [59-77], P < 0.001). Cox regression analysis showed that RDW>15% was an independent prognostic factor for OS (HR 3.654, 95% CI 1.128-11.836) and EFS (HR 2.611, 95% CI 1.012-6-739). Conclusion High baseline RDW is an independent prognostic marker of poor outcome in patients with DLBCL. RDW could be an easily available and inexpensive marker for the risk stratification in patients with DLBCL.

Abstract
Prognostic significance of immune microenvironment has been emphasized using the most advanced analysis, with consecutive attempts to reveal prognostic impact of this findings. The aim of this study was to compare and define prognostic significance of clinical parameters, microvessel density (MVD) in tumour tissue and expression of CD44s as adhesive molecule on tumour cells in diffuse large B cell lymphoma-DLBCL, primary central nervous system DLBCL-CNS DLBCL and follicular lymphoma-FL. A total of 202 histopathological samples (115 DLBCL/65 FL/22 CNS DLBCL) were evaluated. Overall response (complete/partial remission) was achieved in 81.3 % DLBCL patients, 81.8 % primary CNS DLBCL and 92.3 % FL. Absolute lymphocyte count-ALC/Absolute monocyte count-AMC >2.6 in DLBCL and ALC/AMC ≥ 4.7 in FL were associated with better event-free survival (EFS) and overall survival (OS) (p < 0.05). In DLBCL, MVD > 42 blood vessels/0.36 mm(2) correlated with primary resistant disease (p < 0.0001), poorer EFS and OS (p = 0.014). High CD44s expression in FL correlated with inferior EFS and OS (p < 0.01). In DLBCL, multivariate Cox regression analysis showed that ALC/AMC was independent parameter that affected OS (HR 3.27, 95 % CI 1.51-7.09, p = 0.003) along with the NCCN-IPI (HR 1.39, 95 % CI 1.08-1.79, p = 0.01). Furthermore, in FL, ALC/AMC mostly influenced OS (HR 5.21, 95 % CI 1.17-23.21, p = 0.03), followed with the FLIPI (HR 3.98, 95 % CI 1.06-14.95, p = 0.041). In DLBCL and FL, ALC/AMC is simple and robust tool that is, with current prognostic scores, able to define long-term survival and identify patients with inferior outcome. The introduction of immunochemotherapy might altered the prognostic significance of microenvionmental biomarkers (MVD and CD44s).

Abstract
UNLABELLED The neutrophil/lymphocyte ratio (NLR), lymphocyte/monocyte ratio (LMR), and absolute lymphocyte count/absolute monocyte count prognostic score (ALC/AMC PS) have been described as the most useful prognostic tools for patients with diffuse large B-cell lymphoma (DLBCL). We retrospectively analyzed 148 Taiwanese patients with newly diagnosed diffuse large B-cell lymphoma under rituximab (R)-CHOP-like regimens from January 2001 to December 2010 at the Tri-Service General Hospital and investigated the utility of these inexpensive tools in our patients. In a univariate analysis, the NLR, LMR, and ALC/AMC PS had significant prognostic value in our DLBCL patients (NLR: 5-year progression-free survival [PFS], P = 0.001; 5-year overall survival [OS], P = 0.007. LMR: PFS, P = 0.003; OS, P = 0.05. ALC/AMC PS PFS, P < 0.001; OS, P < 0.001). In a separate multivariate analysis, the ALC/AMC PS appeared to interact less with the other clinical factors but retained statistical significance in the survival analysis (PFS, P = 0.023; OS, P = 0.017). The akaike information criterion (AIC) analysis produced scores of 388.773 in the NLR, 387.625 in the LMR, and 372.574 in the ALC/AMC PS. The results suggested that the ALC/AMC PS appears to be more reliable than the NLR and LMR and may provide additional prognostic information when used in conjunction with the International Prognostic Index.

Abstract
INTRODUCTION Diffuse large B-cell lymphoma (DLBCL) is a heterogeneous entity, showing a highly variable outcome. In patients with DLBCL relapsed/refractory to first-line treatment with rituximab the usefulness of the revised International Prognostic Index (R-IPI) as a prognostic tool remains unexplored. Some biological parameters (B-cell lymphoma 6 [Bcl-6], Bcl-2, p53, and multiple myeloma 1 [MUM1]) and blood populations (lymphocyte and monocyte counts) have been described as International Prognostic Index-independent prognostic factors. The objective was to evaluate the R-IPI to predict the outcome of DLBCL patients at the time of relapse after a front-line treatment with chemotherapy and rituximab and to establish in this population the relationship between biological parameters and outcome. PATIENTS AND METHODS We included patients with refractory/relapsed DLBCL after first-line treatment with rituximab-containing regimens; patients must have already finished a rescue treatment also including rituximab. Immunohistochemical assessment of Bcl-2, Bcl-6, p53, and MUM1 expression were undertaken in available biopsies. R-IPI factors were identified from the clinical data at diagnosis and at relapse. Response was assessed using National Cancer Institute-sponsored Working Group guidelines. RESULTS R-IPI prognosis at relapse was not significantly associated with overall response rate (ORR) after Rituximab-chemotherapy rescue therapy. None of the immunohistochemical parameters analyzed correlated with rescue therapy results. In contrast, patients with absolute lymphocyte count (ALC) ≥ 1 × 10(9)/L at relapse were more likely to respond than patients with ALC < 1 × 10(9)/L (P = .05). CONCLUSION The R-IPI score calculated at relapse could not predict the ORR to second-line treatment. Lymphopenia is a simple and useful predictor for outcome in relapsed/refractory DLBCL and the only prognostic factor that in our hands could predict the overall response to a second-line treatment with rituximab and chemotherapy.

Abstract
To evaluate the prognostic value of the absolute lymphocyte count/absolute monocyte count ratio (ALC/AMC ratio) at diagnosis in diffuse large B-cell lymphoma (DLBCL), we performed a meta-analysis of published studies that provided survival information with reference to the ALC/AMC ratio at diagnosis. Nine studies covering a total of 4198 subjects were included in this analysis. The summary hazard ratios of low ALC/AMC ratio for overall survival were 2.00 (p = 0.000) in the population that received R-CHOP (rituximab, cyclophosphamide, doxorubicin, vincristine, prednisone) and 1.12 (p = 0.479) in the population that received CHOP. The corresponding ratios for event-free survival and progression-free survival were 1.93 (p = 0.000) and 2.31 (p = 0.000) in the population that received R-CHOP. These results may justify risk-adapted therapeutic strategies for patients with DLBCL treated with R-CHOP to account for the ALC/AMC ratio at diagnosis.

Abstract
The introduction of rituximab and generally improved health among elderly patients have increased the survival of patients with diffuse large B-cell lymphoma (DLBCL). The International Prognostic Index (IPI) from 1992 is based on pre-rituximab data from clinical trials including several lymphoma subtypes. We applied IPI factors to a population-based rituximab-treated cohort of 1990 patients diagnosed 2000-2010 and explored new factors and the optimal prognostic age cut-off for DLBCL. Multivariate-analyses (MVA) confirmed the prognostic value of all IPI factors except the presence of > 1 extranodal lesion. The optimal age cut-off was 70 years. In a MVA of albumin, lymphocyte count, sex, immunoglobulin G, bulky disease, hemoglobin and B-symptoms, only albumin was prognostic. We propose: (1) a modified DLBCL prognostic index (DLBCL-PI) including: age (70 years), performance status (PS), lactate dehydrogenase (LDH), stage and albumin level, and (2) a separate age-adjusted DLBCL-PI for patients ≤ 70 years including PS, LDH, albumin level and > 1 extranodal lesion, however excluding stage.

Prognostic factors for diffuse large B-cell lymphoma in the R(X)CHOP era. Ann Oncol 2014; 25:2124-2133.

Abstract
BACKGROUND The introduction of rituximab (R) to conventional CHOP chemotherapy for newly diagnosed diffuse large B-cell lymphoma (DLBCL) led to an unequivocal improvement in survival, establishing RCHOP as the standard of care. Still, nearly 40% of DLBCL patients will eventually die of relapsed disease. Efforts to improve outcomes by addition of new biologic agents (X) to the RCHOP backbone are underway. In this era of R(X)CHOP, it is imperative to develop prognostic and predictive markers, not only to identify patients who will suffer a particularly aggressive course, but also to accurately select patients for clinical trials from which they will most benefit. DESIGN The following review was undertaken to describe prognostic factors in DLBCL, with emphasis on markers that are accurate, relatively available, and clinically applicable in 2014. RESULTS The International Prognostic Index retains its validity in the era of RCHOP, although with limited ability to predict those with <50% chance of long-term survival. Gene expression profiling has provided novel insights into the biology of DLBCL and led to the development of immunohistochemistry (IHC) algorithms that are in routine practice. Identification of a 'double-hit' (DH) lymphoma by fluorescent in situ hybridization with aberrations involving MYC and/or BCL2 and BCL6 genes has important implications due to its extremely dismal prognosis with RCHOP. Other markers such as the absolute lymphocyte count (ALC), serum immunoglobulin free light chains, vitamin D levels, serum cytokines/chemokines, and imaging with positron emission tomography (PET) have all shown promise as future predictive/prognostic tests. CONCLUSIONS The future for new treatment options in DLBCL is promising with current clinical trials testing novel targeted agents such as bortezomib, lenalidomide, and ibrutinib as the 'X' in R(X)CHOP. Predictive factors are required to select and randomize patients appropriately for these trials. We envision the day when 'X' will be chosen based on the biological characteristics of the tumor.

Influence of NK cell count on the survival of patients with diffuse large B-cell lymphoma treated with R-CHOP. Blood Res 2014; 49:162-9.

Abstract
Background Although adding rituximab to the chemotherapy regimen of cyclophosphamide, vincristine, doxorubicin, and prednisone (R-CHOP) has improved clinical outcomes of patients with diffuse large B-cell lymphoma (DLBCL), several recent studies have shown that the effect of rituximab is dominantly in the non-germinal center (non-GC) subtype compared to the germinal center (GC) subtype. Natural killer (NK) cell count, a surrogate marker of immune status, is associated with clinical outcomes in DLBCL patients in the rituximab era. We investigated whether the impact of NK cells on clinical outcomes differed according to the immunophenotype of DLBCL. Methods This study analyzed 72 DLBCL patients treated with R-CHOP between January 2010 and January 2014. Results Low NK cell counts (<100/µL) were associated with poor progression-free survival (PFS) and overall survival (OS) compared to high NK cell counts. In multivariate analysis, low NK cell count was an independent prognostic factor for PFS and OS. However, survival did not significantly differ between the GC and non-GC subtypes. We examined the clinical influence of NK cells according to the immunophenotype and found that low NK cell counts were significantly associated with poor PFS and OS in non-GC cases, but not in GC cases. Conclusion Low NK cell counts at diagnosis are associated with poor clinical outcomes in DLBCL patients treated with R-CHOP therapy. However, the impact is significant only in non-GC subtype DLBCL, not in the GC subtype.

Abstract
Background Despite the use of modern immunochemotherapy regimens, a significant proportion of diffuse large B-cell lymphoma (DLBCL) patients will relapse. We proposed absolute lymphocyte count/absolute monocyte count ratio (ALC/AMC ratio) as a new prognostic factor in relapsed or primary refractory DLBCL. Methods We retrospectively analyzed 163 patients who have been diagnosed with relapsed or primary refractory DLBCL. The overall survival (OS) and progression-free survival (PFS) were measured from the time of first relapse. The Cox proportional hazards model was used to evaluate ALC/AMC ratio as prognostic factors for OS and PFS. Results On univariate and multivariate analysis performed with factors included in the saaIPI, early relapse, prior exposure to rituximab and autologous stem-cell transplantation (ASCT), the ALC/AMC ratio at the time of first relapse remained an independent predictor of PFS and OS (PFS: P < 0.001; OS: P < 0.001). Patients with lower ALC/AMC ratio (<2.0) had lower overall response rate, 1-year PFS and 2-year OS rate compared with those with higher ALC/AMC ratio (≥2.0). Moreover, the ALC/AMC ratio can provide additional prognostic information when superimposed on the saaIPI. Conclusions Lower ALC/AMC ratio at the time of first relapse is a adverse prognostic factor for OS and PFS in relapsed or primary refractory DLBCL, and leads to the identification of high-risk patients otherwise classified as low/intermediate risk by the saaIPI alone.

Abstract
OBJECTIVES The tumor microenvironment, including tumor-infiltrating lymphocytes and myeloid-derived cells, is an important factor in the pathogenesis and clinical behavior of malignant lymphoma. However, the prognostic significance of peripheral lymphocytes and monocytes in lymphoma remains unclear. METHODS We evaluated the prognostic impact of the absolute lymphocyte count (ALC), absolute monocyte count (AMC), and lymphocyte/monocyte ratio (LMR) in 359 diffuse large B-cell lymphoma (DLBCL) patients treated with rituximab plus cyclophosphamide, doxorubicin, vincristine, and prednisone (R-CHOP). RESULTS The median follow-up time of the surviving patients was 58 months. Low ALC and an elevated AMC were both associated with poor survival rates. Receiver operating characteristic curve analysis showed that LMR was the best predictor of survival, with 4.0 as the cutoff point. Patients with LMR ≤4.0 were more likely to have an aggressive tumor, and this was associated with poor treatment responses. Patients with LMR ≤4.0 at diagnosis had significantly poorer overall survival (OS) and progression-free survival (PFS) than those with LMR >4.0. Multivariate analysis, which included prognostic factors of the International Prognostic Index, showed LMR ≤4.0 to be an independent predictor for the OS (hazard ratio [HR], 2.507; 95% confidence interval [CI], 1.255-5.007; P = 0.009) and PFS (HR, 2.063; 95% CI, 1.249-3.408; P = 0.005). CONCLUSIONS The LMR at diagnosis, as a simple index which reflects host systemic immunity, predicts clinical outcomes in DLBCL patients treated with R-CHOP.

Abstract
Background Paraquat (PQ) is a potent, highly toxic and widely used herbicide. The major medical problems associated with PQ are accidental or suicidal ingestion. There are several prognostic markers of PQ poisoning, with the serum PQ concentration considered to be the best indicator of outcome. However, the measurement of such markers is limited in many hospitals. Objective The present study was conducted to investigate the association of absolute lymphocyte count (ALC) and the 30-day mortality rate in patients with PQ poisoning. Methods We performed a retrospective analysis of patients admitted to the emergency department after paraquat poisoning between January 2010 and April 2013. Independent risk factors including ALC for 30-day mortality were determined. The ALC was categorized in quartiles as ≤1700, 1700 to 3200, 3200 to 5000, and >5000. Univariate and multivariate Cox proportional hazard analysis were performed to determine the independent risk factors for mortality. Results A total of 136 patients were included in the study, and the 30-day mortality was 73.5%. ALC was significantly higher in nonsurvivors than in survivors. The highest ALC quartile (ALC>5000; hazard ratio, 2.58; 95% CI, 1.08–6.21) was associated with increased mortality in multivariate analysis. In addition, old age, lower arterial PaCO2, increased peripheral neutrophil count, and high serum levels of creatinine were associated with mortality. Conclusion The absolute lymphocyte count is associated with the 30-day mortality rate in patients with paraquat poisoning.

Abstract
To determine whether peripheral blood absolute lymphocyte/absolute monocyte counts ratio (ALC/AMC ratio) at diagnosis predicts survival of diffuse large B cell lymphoma (DLBCL) patients treated with standard first-line regimens, we retrospectively analyzed 244 patients with DLBCL who were treated with standard cyclophosphamide, hydroxydaunorubicin, vincristine, and prednisone, or rituximab-cyclophosphamide, hydroxydaunorubicin, vincristine, and prednisone. Progression-free survival and overall survival (PFS and OS) were estimated using the Kaplan-Meier method and two-tailed log-rank; The Cox proportional hazards model was used to evaluate ALC/AMC ratio as prognostic factors when adjusting for the International Prognostic Index (IPI). On univariate and multivariate analyses performed with factors included in the IPI, the ALC/AMC ratio at diagnosis remained an independent predictor of OS and PFS (OS: P < 0.001; PFS: P < 0.001). Patients with lower ALC/AMC ratio (<3.8) seemed to have lower complete remission rate, 2-year PFS and 3-year OS when compared to patients with ALC/AMC ratio ≥3.8, respectively (26 versus 90 %, P < 0.001; 18 versus 82 %, P < 0.001; 24 versus 86 %; P < 0.001, respectively). Moreover, the ALC/AMC ratio was able to further risk-stratify IPI 0-2 and three-five risk patient groups, respectively. The ALC/AMC ratio at the time of diagnosis may provide additional prognostic information beyond that of the IPI for patients with DLBCL who receive standard first-line regimens.

Abstract
Background Peripheral T-cell lymphoma, not otherwise specified (PTCL-NOS) is a heterogeneous group of aggressive T-cell lymphomas with poor treatment outcomes. The aim of this study was to evaluate whether lymphopenia at diagnosis would have an adverse effect on survival in patients with PTCL-NOS treated with anthracycline-containing chemotherapy. Methods A total of 118 patients with PTCL-NOS treated with anthracycline-containing chemotherapy from 4 Korean institutions were included. Results Thirty-six patients (30.5%) had a low absolute lymphocyte count (ALC, < 1.0 × 109/L) at diagnosis. Patients with lymphopenia had shorter overall survival (OS) and progression-free survival (PFS) rates compared with patients with high ALCs (P = 0.003, P = 0.012, respectively). In multivariate analysis, high-intermediate/high-risk International Prognostic Index (IPI) scores and lymphopenia were both associated with shorter OS and PFS. Treatment-related mortality was 25.0% in the low ALC group and 4.8% in the high ALC group (P = 0.003). In patients considered high-intermediate/high-risk based on IPI scores, lymphopenia was also associated with shorter OS and PFS (P = 0.002, P = 0.001, respectively). Conclusion This study suggests that lymphopenia could be an independent prognostic marker to predict unfavorable OS and PFS in patients with PTCL-NOS treated with anthracycline-containing chemotherapy and can be used to further stratify high-risk patients using IPI scores.

Lymphopenia following the completion of first-line therapy predicts early relapse in patients with diffuse large B cell lymphoma. Ann Hematol 2011; 91:375-82.

Abstract
Early relapse is a parameter that affects clinical outcomes in relapsed diffuse large B cell lymphoma (DLBCL). The prognostic value of lymphopenia following the completion of first-line therapy and the relationship between lymphopenia and early relapse are unknown. Therefore, we studied the role of absolute lymphocyte count (ALC) on early relapse. We retrospectively analyzed de novo DLBCL patients who were treated with rituximab-containing treatment between 2003 and 2010. The median age at the time of diagnosis of 59 DLBCL patients was 71 years. We identified no association between ALC at diagnosis and ALC following the completion of first-line therapy. Among all patients analyzed, 13 (22%) patients were confirmed to exhibit early relapse. Low ALC following the completion of first-line therapy was significantly associated with early relapse by univariate analysis [hazard ratio (HR) = 4.05; 95% confidence interval (CI), 1.11-14.73; P = 0.02] and multivariate analysis (HR = 4.66; 95% CI, 1.24-17.48; P = 0.023). The low ALC group tended to have worse outcomes than the high ALC group with lower rates of progression-free survival (66% and 74%, respectively; P = 0.13) and overall survival (74% and 86%, respectively; P = 0.09), but these differences did not reach statistically. Lymphopenia following the completion of first-line therapy can be used as a marker to predict early relapse.

Abstract
Despite the use of modern immunochemotherapy regimens, almost 50% of patients with diffuse large-B-cell lymphoma will relapse. Current prognostic models, including the International Prognostic Index, incorporate patient and tumor characteristics. In contrast, recent observations show that variables related to host adaptive immunity and the tumor microenvironment are significant prognostic variables in non-Hodgkin lymphoma. Therefore, we retrospectively examined the absolute monocyte and lymphocyte counts as prognostic variables in a cohort of 366 diffuse large-B-cell lymphoma patients who were treated between 1993 and 2007 and followed at a single institution. The absolute monocyte and lymphocyte counts in univariate analysis predicted progression-free and overall survival when analyzed as continuous and dichotomized variables. On multivariate analysis performed with factors included in the IPI, the absolute monocyte and lymphocyte counts remained independent predictors of progression-free and overall survival. Therefore, the absolute monocyte and lymphocyte counts were combined to generate a prognostic score that identified patients with an especially poor overall survival. This prognostic score was independent of the IPI and added to its ability to identify high-risk patients.

Abstract
Rapid lymphocyte recovery after bone marrow or peripheral blood transplantation is associated with improved survival. However, the impact of early lymphocyte recovery has not been examined after umbilical cord blood transplant (UCBT). We evaluated lymphocyte recovery in 360 consecutive patients with hematologic malignancy that underwent UCBT between 2001 and 2007. Uniform myeloablative (MA), reduced intensity conditioning (RIC) and graft-versus-host disease prophylaxis regimens were used. In multivariate analysis, an absolute leukocyte count (ALC) >200 × 10(6)/L at day 30 (n = 73) after MA conditioning was associated with superior 2-year overall survival (OS) (73% versus 61%; P = .02) (relative risk [RR]: 2.29; 95% confidence interval [CI]: 1.15-4.56), progression-free survival (PFS) (68% versus 54%; P = .05) (RR: 1.96; 95% CI: 0.99-3.86) and less transplant-related mortality (8% versus 28%, P < .01) (RR: 4.38; 95% CI: 1.65-11.60) compared to ≤200 × 10(6)/L (n = 43). Similarly, an ALC >200 × 10(6)/L at day 42 (n = 105) after RIC was associated with superior 2-year OS (59% versus 41%, P < .01) (RR: 2.10; 95% CI: 1.3-3.41) and PFS (46% versus 36%, P = .05) (RR: 1.58; 95% CI: 1.01-2.49) compared to ≤200 × 10(6)/L (n = 55). There was no significant relationship between ALC and relapse. Rapid lymphocyte recovery early after UCBT predicts better survival in patients with hematologic malignancies.

Abstract
A specific predictor during routine follow-up to ascertain risk for relapse after standard chemotherapy in non-Hodgkin's lymphoma (NHL) has not been identified. Thus, we studied absolute lymphocyte count (ALC) as a marker of poststandard chemotherapy (rituximab, cyclophosphamide, adriamycin, vincristine and prednisone (R-CHOP)) NHL relapse in patients with diffuse large B-cell lymphoma (DLBCL). ALC was obtained at the time of confirmed relapse and at last follow-up. From 2000 until 2006, 149 consecutive DLBCL patients, originally diagnosed, treated with R-CHOP and followed up at Mayo Clinic, Rochester, were included in this study. Patients at last follow-up without relapse (N=112) had a higher ALC compared with those with relapsed lymphoma ((N=37) median ALC x 10(9)/l of 1.43 (range: 0.33-4.0) versus 0.67 (range: 0.18-1.98), P<0.0001, respectively). ALC at the time of confirmed relapse was a strong predictor for relapse with an area under the curve =0.91 (P<0.0001). An ALC <0.96 x 10(9)/l at the time of confirmed relapse had a positive predictive value of 72% and a positive likelihood ratio of 7.4 to predict relapse after R-CHOP in DLBCL. Patients with an ALC>or=0.96 x 10(9)/l (N=103) had a cumulative incidence of relapse of 6 versus 79% with an ALC <0.96 x 10(9)/l (N=46) (P<0.0001). This study suggests that lymphopenia measured by ALC can be used as a marker to assess risk of DLBCL relapse during routine follow-up after standard chemotherapy.

Abstract
BACKGROUND Rituximab has dramatic impact on outcome of patients with diffuse large B-cell lymphoma (DLBCL), especially nongerminal center (non-GC) type. A low absolute lymphocyte count (ALC) before rituximab, cyclophosphamide, vincristine, adriamycin, and prednisone (R-CHOP) therapy as a surrogate marker of immune status is associated with poor clinical outcome in DLBCL. Therefore, we hypothesized that low ALC before R-CHOP would have effect on the survival in non-GC type. PATIENTS AND METHODS One hundred and thirty-six DLBCL patients who were treated with R-CHOP from 2003 to 2007 were analyzed in the present study. RESULTS ALC > or = 1.0 x 10(9)/l predicted a longer 3-year progression-free survival (PFS) and 3-year overall survival (OS) versus ALC <1.0 x 10(9)/l (82.6% versus 60.0%, P = 0.005 and 87.2% versus 62.0%, P < 0.001, respectively). Non-GC type had similar PFS and OS to germinal center type (68.2% versus 80.0%, P = 0.074 and 72.7% versus 82.9%, P = 0.111, respectively). However, considering clinical influence of the ALC according to immunophenotype, low ALC in non-GC type DLBCL was associated with lower PFS and OS compared with others (PFS, P = 0.002; OS, P < 0.001). Multivariate analysis revealed that low ALC in non-GC type had lower PFS [hazard ratio (HR) = 3.324, P = 0.001] and OS (HR = 4.318, P < 0.001), independent of international prognostic index. CONCLUSION A low ALC in non-GC type DLBCL counteracted the beneficial effect of rituximab on survival.

Abstract
The prognostic value of absolute lymphocytic count (ALC), has been a recent matter of debate in non-Hodgkin-lymphoma (NHL). We assessed prospectively the value of ALC at diagnosis and also after the completion of immuno-chemotherapy in 101 diffuse-large-B-cell-lymphoma (DLBCL). Analysis of prognostic factors with respect to overall survival (OS), event free survival (EFS) and progression free survival (PFS) was done by two-tailed log-rank test. The ALC cut-off value was calculated as <0.84 x 10(9)/L at diagnosis: this was a strong negative prognostic factor for OS (p = 0.0004), EFS (p < 0.00001) and PFS (p < 0.00001) and in multivariate analysis was independent from the revised-international-prognostic-index (R-IPI). ALC after chemo-immunotherapy was not of prognostic value. As R-IPI and ALC < 0.84 x 10(9)/L, were the factors better discriminating poor prognosis, a new trichotomous score (ALC/R-IPI) was built up: (1) low risk: R-IPI = very good or good and ALC < 0.84 x 10(9)/L; (2) intermediate risk: patients with at least one risk factor (R-IPI = poor or ALC < 0.84 x 10(9)/L). (3) high risk: patients with both risk factors. This new prognostic score was highly significant in univariate analysis for OS (p = 0.0002), EFS (p < 0.00001) and PFS (p < 0.00001). In multivariate analysis ALC/R-IPI was the most predictive factor for OS (OR = 2.954; p = 0.002) and EFS (OR = 2.381; p < 0.00001) and the only predictive factor for PFS (OR = 4.018; p < 0.00001). Our data, show that ALC at diagnosis has a strong prognostic relevance and is independent from the R-IPI. The new score including both values proved the most powerful predictor at multivariate analysis.

Abstract
OBJECTIVES To evaluate the prognostic value of absolute lymphocyte count (ALC) at diagnosis in patients with diffuse large B-cell lymphoma (DLBCL). METHODS In a large cohort of patients with DLBCL treated with CHOP (n = 119) or RCHOP (n = 102) in our institution, we evaluated the prognostic value of ALC at diagnosis with regards to treatment response, overall (OS) and progression-free survival (PFS). Use of rituximab, all International Prognostic Index (IPI) determinants, beta2microglobulin level, presence of B symptoms or bulky disease, and ALC were evaluated. RESULTS Low ALC (<1.0 x 10(9)/L) was associated with advanced stage, performance status >or=2, elevated lactate dehydrogenase, number of extranodal involvement >or=2, B symptoms, elevated beta2microglobulin and higher IPI risk group. Low ALC was associated with lower CR rate by univariate analysis (odds ratio = 3.29, P = 0.024) but not by multivariate analysis. By univariate analysis using Cox proportional hazard model, low ALC was associated with shorter OS [hazard ratio (HR) = 2.89, P < 0.001] and PFS (HR = 2.91, P < 0.001). Multivariate analysis revealed that low ALC was associated with shorter OS (HR = 2.51, P = 0.003) and PFS (HR = 2.72, P < 0.001), independent of above-mentioned parameters. Subclass analyses revealed that the use of rituximab improves OS in patients with low ALC (HR = 0.42, P = 0.05) but not in those with high ALC (HR = 0.83, P = 0.71). This observation was most obvious in patients with higher IPI score. CONCLUSION Low ALC is a poor prognostic marker in patients with DLBCL and suggests patients' survival benefit from rituximab.
