Peripheral T-cell lymphoma (PTCL) is an aggressive and heterogenous T-cell lymphoid malignancy. The prognostic value of C-reactive protein-to-albumin ratio (CAR) has never been assessed in PTCL.This study retrospectively reviewed the medical records of 76 patients diagnosed with various subtypes of PTCL. A CAR cutoff value of 0.794 was determined, and clinical outcomes, including response rate, overall survival (OS), and progression-free survival (PFS), were compared between the high ( 0.794) and low (≤ 0.794) CAR groups.After induction therapy, complete response was achieved in 8 (32.0%) and 39 patients (76.5%) in the high and low CAR groups, respectively. During the median follow-up of 57.5 months, the high CAR group had significantly worse 5-year PFS and 5-year OS rates. Even with adjustment for the International Prognostic Index (≥ 3), Prognostic Index for PTCL-unspecified (≥ 3), and T cell score (≥ 2), high CAR remained a significant prognostic factor for PFS (hazard ratio [HR]: 4.01, 95% confidence interval [CI] 2.04-7.86, p 0.001) and OS (HR: 2.97, 95% CI: 1.33-6.64, p = 0.008).CAR may play a complementary role in predicting prognosis in patients with PTCL, considering its simplicity, objectivity, and easy accessibility.

Background: Peripheral T cell lymphoma (PTCL) is a heterogeneous entity with poor survival. We evaluated the neutrophil-to-lymphocyte ratio (NLR), absolute lymphocyte count (ALC), and platelet count as new prognostic factors for PTCL. Patients and Methods: We retrospectively analyzed 77 patients with PTCL initially treated with anthracycline-based chemotherapy. Survival curves were compared between groups with different initial NLR (iNLR), end-point NLR (eNLR), initial ALC, and platelet counts. Cox regression was used to analyze the risk factor for survival. Results: Patients with a higher eNLR (≥3), lymphopenia (< 1,000/μL), and thrombocytopenia (< 150 K/μL) had an inferior progression-free survival (PFS) and overall survival (OS) compared to their counterparts, while a higher iNLR (≥3) was predictive of a shorter OS but not PFS. Among these, thrombocytopenia was an independent poor prognostic factor for both PFS and OS, with a hazard ratio of 2.42 (p = 0.012) for PFS and 4.21 (p = 0.006) for OS. The presence of thrombocytopenia further stratified patients with a worse prognosis within overlapping risk-groups by the prognostic index for PTCL. Conclusions: Our study showed that thrombocytopenia at diagnosis was an independent prognostic factor for survival in patients with PTCL.

Primary central nervous system lymphoma (PCNSL) is an extranodal NHL with highly aggressive features. However, the importance of the NLR has never been assessed in PCNSL. This retrospective study enrolled 62 biopsy-proven patients whose baseline NLR was available, and reviewed their medical records to compare both high (≥2.0) and low NLR (

Introduction Diffuse large B cell lymphoma (DLBCL) is the most common highly aggressive non-Hodgkin lymphoma (NHL) worldwide. The International Prognostic Index (IPI) has been established as a useful prognostic marker, and there have been some proposed markers which could reflect tumor microenvironment including neutrophil, lymphocyte, platelet, serum globulin, ferritin and serum free light chain. C-reactive protein (CRP) is one of the commonly used inflammatory markers, and its clinical relevance has been suggested recently in various malignancies. Serum albumin is a representative marker for nutritional status, and previous studies have presented that hypoalbuminemia might be an indicator of cancer-related inflammation as well. In this point of view, C-reactive-to-albumin ratio (CAR) has been suggested as one of easily-accessible parameters which could be a robust prognostic marker in diverse malignancies such as lung cancer, gastric cancer and colorectal cancer. However, its clinical value has not been assessed in hematologic malignancies. In this study, we evaluated the prognostic effect of CAR in DLBCL. Methods This retrospective study included 186 patients who were histologically diagnosed with DLBCL and treated with R-CHOP (Rituximab, Cyclophosphamide, Doxorubicin, Vincristine and Prednisone) between 2006 and 2018 at National Cancer Center, Korea. One hundred forty one cases were identified whose baseline laboratory values including CRP and albumin were available, and then the medical records were reviewed. To define the appropriate cutoff value of CAR in patients with DLBCL, cutoff finder method was applied which had been suggested by Budczies et al., and the most discriminative point was designated by the value of 0.158. Clinical characteristics and outcomes including response rate, overall survival (OS) and progression-free survival (PFS) were investigated between high and low CAR group. Additionally, the clinical value of CAR was compared to the components of IPI for DLBCL as well. Results Of all patients, 73 (51.8%) were classified as high CAR group. Male was 42 (57.5%) in high CAR group and 37 (54.4%) in low CAR group. In terms of IPI, 21 (28.8%) were classified into high IPI (score of 4 or 5) in high CAR group - 6 (8.8%) in low CAR group in comparison. Hans criteria was applied to discriminate germinal center B-cell (GCB) subtype to non-GCB subtype by immunohistochemistry and after 12 patients removed due to missing GCB status, 56 (84.8%) in high CAR group was sorted to non-GCB type - 46 (73.0%) in low CAR group to be compared. The high CAR group showed significantly worse complete response (CR) rates to induction R-CHOP therapy (64.4% vs. 92.6%; p60), stage (III, IV), lactate dehydrogenase (LDH) (>upper normal limit), Eastern Cooperative Oncology Group (ECOG) performance status (>1) and the number of extranodal involvement (>1), high CAR showed statistically significant results for both 5-year OS (HR 4.71, 95% CI 1.175-18.892; p=0.029) and 5-year PFS (HR 2.66, 95% CI 1.122-6.289; p=0.026) (Table 1). Conclusions In conclusion, CAR might play an additional role to IPI in prognostication of patients with DLBCL considering the fact that it is simple, objective and easy to obtain.
