ABSTRACT
Objective: To investigate the prognostic value of prognostic nutritional index (PNI) in patients with diffuse large B-cell lym-phoma (DLBCL). Methods: We retrospectively reviewed the medical records of 82 patients with DLBCL treated at Tianjin Union Medi-cal Center between June 2010 and June 2016. The optimal cutoff value of PNI was determined using a receiver operating characteristic (ROC) curve and the Youden index. The relationship of high and low PNI with the clinical characteristics of the patients, therapeutic ef-ficacy, and prognosis were analyzed. Results: Overall, mean PNI of the patients was 46.17±8.8. When the PNI was 44.15, the Youden in-dex was found to be maximal, with a sensitivity of 74.6% and specificity of 67.2%. There were 38 patients (46.3%) in the low PNI group (<44.15) and 44 patients (53.7%) in the high PNI group (≥44.15). Data analysis showed that PNI was correlated with Eastern Coopera-tive Oncology Group performance status (ECOG PS), Ann Arbor stage, international prognostic index (IPI) score, and lactic acid dehydro-genase (LDH) level (P<0.05). The total effective rate of the low PNI group was significantly lower than that of the high PNI group (65.8% vs. 86.4%; χ2=4.848; P=0.028). The 3-year overall survival (OS) rate of the entire group of patients was 69.1%. The 1-, 2-, and 3-year OS rates of the low PNI group (86.8%, 67.8%, and 56.9%, respectively) were significantly lower than that of the high PNI group (96.7%, 89.5%, and 80.2%, respectively; χ2=9.421, P=0.002). Univariate analysis showed that PNI<44.15, ECOG PS≥2, IPI>2, stageⅢ/Ⅳ, and lymphocyte count<1.0×109/L had a significant impact on predicting OS (P<0.05). Multivariate analysis showed that PNI<44.15 (P=0.006) and stageⅢ/Ⅳ(P=0.011) were independent factors for predicting OS. Conclusions: PNI might be used as a simple and feasible clinical prognostic indicator in patients with DLBCL.
ABSTRACT
Objective To evaluate the efficacy and safety of neurokinin1 (NK1) receptor antagonist aprepitant combined with prednisone and tropisetron in prevention of nausea and vomiting (CINV) induced by R-CHOP or CHOP regimen. Methods A total of 90 patients with diffuse large B-cell lymphoma (DLBCL) who accepted R-CHOP or CHOP regimen in the People''s Hospital of Tianjin from October 2015 to January 2016 were divided into aprepitant group (45 cases) and the control group (45 cases) according to the random number table. In aprepitant group, day 1: aprepitant 125 mg 1 h before chemotherapy, prednison 100 mg, tropisetron 10 mg, and tropisetron 5 mg 2 hours after chemotherapy;day 2-3:aprepitant 80 mg and prednison 100 mg, tropisetron 10 mg; day 4-5: prednison 100 mg. In the control group, day 1: prednison 100 mg 1 h before chemotherapy, tropisetron 10 mg, and tropisetron 5 mg 2 h after chemotherapy; days 2-3: prednison 100 mg, tropisetron 10 mg; day 4-5: prednison 100 mg. Data on nausea, vomiting and remission treatment were collected every day. The complete remission (CR) rates of CINV without vomiting and remission drugs in the whole cycle were recorded. Functional living index-emesis questionnaire (FILE) was used to assess the effect of CINV on the life quality of the patients. Results CR in aprepitant group was higher than that in the control group (77.8 ％ vs. 55.6 ％, χ2= 5.000, P= 0.025). The rate of no vomiting in aprepitant regimen was higher than that in the control regimen (82.2 ％ vs. 62.2 ％, χ2 = 4.486, P= 0.034). The average scores of FILE between the two groups were (113 ±10) and (100 ±11) scores respectively, and there was a significant difference (t=12.437, P<0.001). The related adverse reactions of vomiting-stopping drugs in both groups had no statistical difference. Conclusion The aprepitant combined with tropisetron and prednisone can improve effectively nausea and vomiting induced by R-CHOP or CHOP chemotherapy regimen for DLBCL patients.
ABSTRACT
Objective:To compare the therapeutic efficacy and safety of Hyper-CVAD/MA regimen and CHOP/CHOP-like regimen in the treatment of peripheral T-cell lymphoma, not otherwise specified (PTCL-NOS). Methods:The 78 primary PTCL-NOS patients who were initially diagnosed and treated in Tianjin Medical University Cancer Institute and Hospital and Tianjin Union Medical Center from June 2004 to June 2012 were retrospectively analyzed. The patients were then divided into two groups:Hyper-CVAD/MA group (n=21) and CHOP/CHOP-like group (n=57). Curative efficacies and toxicities were analyzed by Chi-square test, and survival was estimated by Ka-plan-Meier method. Results: In the Hyper-CVAD/MA group, complete response (CR) was 42.9%, overall response rate (ORR) was 85.7%, median progression-free survival (PFS) was 20 months, and the three-year overall survival (OS) was 56.9%. In the CHOP/CHOP-like group, the CR, ORR, and three-year OS were 28.1%, 59.6%, and 49.6%, respectively, and the median PFS was 13 months. Compara-tive analysis showed that the ORR and three-year OS were statistically significant (P0.05). The incidence rates ofⅢ/Ⅳneutrocytopenia and thrombocytopenia in Hyper-CVAD/MA group (66.7%and 61.9%, respectively) were significantly higher than those of the CHOP/CHOP-like group (22.8%and 14.0%, respec-tively) (P<0.05). Conclusion:Hyper-CVAD/MA regimen can achieve satisfactory efficacy in parents with PTCL-NOS, and toxicity can be controlled with granulocyte colony stimulating factor (G-CSF).
