Inflammation has been demonstrated to be widely involved in the carcinogenesis of nasopharyngeal carcinoma (NPC). However, the prognostic significance of lymphocyte to monocyte ratio (LMR) in metastatic NPC is not fully addressed. The purpose of the study is to investigate the prognostic impact of pre-treatment absolute lymphocyte count (ALC), absolute monocyte count (AMC), and LMR on patients with newly diagnosed metastatic NPC undergoing chemotherapy. Between January 2006 and December 2010, patients with newly diagnosed metastatic NPC undergoing chemotherapy were retrospectively collected. The prognostic significance of baseline clinical features and inflammatory markers was investigated. A total of 256 patients were eligible for the study. The best cut-off value of ALC, AMC, and LMR was 2.25 × 10/L, 0.35 × 10/L, and 5.07, respectively. Patients in the high LMR group had a significantly longer overall survival (OS) (25.0 months [24.50-25.49]) than patients in the low LMR group (16.0 months [15.51-16.49]; p < 0.001). In addition, ALC ≥ 2.25 × 10/L (HR, 0.59; 95 % CI, 0.43-0.81; p = 0.001) and LMR ≥5.07 (HR, 0.42; 95 % CI, 0.30-0.59; p < 0.001) remained as independent prognostic factors for superior OS, while AMC did not retained its prognostic significance in COX multivariate analysis. Pre-treatment ALC and LMR were demonstrated to be independent prognostic factors in patient with newly diagnosed metastatic NPC receiving chemotherapy. Future prospective studies are needed to validate the findings. [ABSTRACT FROM AUTHOR]

Little is known about the likelihood and degree of hepatitis B virus (HBV) reactivation in hepatitis B surface antigen (HBsAg) seropositive patients with disseminated non-small cell lung cancer (NSCLC) receiving chemotherapy. Between January 2003 and December 2013, all HBsAg seropositive patients with metastatic NSCLC receiving cytotoxic chemotherapy were retrospectively evaluated. The morbidity and mortality of HBV reactivation, risk factors associated with reactivation, as well as the efficacy of preemptive lamivudine were investigated. Of 258 patients who were eligible for the present study, 176 were treated without antiviral prophylaxis and 82 received preemptive lamivudine. Patients without lamivudine prophylaxis had a significantly higher prevalence of HBV reactivation (19.3 vs 6.1 %, p = 0.006) and severe hepatitis attributable to reactivation (11.8 vs 3.7 %, p = 0.034) than those with preemptive lamivudine. However, no significant difference in mortality due to reactivation was noted between patients with or without prophylactic lamivudine (0 vs 2.3 %, p = 0.310). Furthermore, patients who developed HBV reactivation were indentified to have a higher rate of HBeAg seropositivity (74.4 vs 43.4 %, p < 0.001), serum HBV-DNA level of 10 copies/ml or greater (76.9 vs 47.9 %, p = 0.001), coexisting liver metastasis (50.0 vs 40.6 %, p = 0.033) and treatment with more than 4 cycles of chemotherapy (56.4 vs 39.3 %, p = 0.046) than those who did not experienced reactivation. The current study has demonstrated that preemptive lamivudine significantly reduced the prevalence of HBV reactivation in HBsAg seropositive patients with metastatic NSCLC receiving systemic chemotherapy.

The link between circulating lymphocyte-to-monocyte ratio (LMR) and newly diagnosed metastatic non-small cell lung cancer (NSCLC) is not fully defined. The study was conducted to evaluate the prognostic impact of LMR on survival outcomes in previously untreated metastatic NSCLC patients receiving platinum-based doublet. Chemotherapy-naive metastatic NSCLC patients undergoing platinum-based doublet were retrospectively enrolled. Clinical features regarding gender, age, Eastern Cooperative Oncology Group (ECOG) performance status, histology, absolute lymphocyte count (ALC), absolute monocyte count (AMC) and LMR were collected to determinate their prognostic impact on progression-free survival (PFS) and overall survival (OS). Up to 370 patients were eligible for the study. By univariate analysis, ECOG performance status, histology, ALC, AMC and LMR were showed to be significantly associated with PFS and OS. In subsequent Cox multivariate analysis, non-squamous cell carcinoma, ALC ≥2.45 × 10/L, AMC <0.45 × 10/L and LMR ≥4.56 were demonstrated to be independently correlated with better PFS. In addition, independent favorable prognostic factors for OS were only limited to LMR ≥4.56 and non-squamous cell carcinoma, whereas ECOG performance status of 2 and AMC ≥0.45 × 10/L remained as independently inferior prognostic indicators for OS. Our findings implicate that circulating AMC and LMR are regarded as independent prognostic factors for PFS and OS in previously untreated metastatic NSCLC patients receiving platinum-based doublet.

The association of prolonged rituximab therapy and hepatitis B virus (HBV) reactivation in diffuse large B-cell lymphoma (DLBCL) and the role of lamivudine prophylaxis remain undefined. The prevalence and mortality of HBV reactivation in HBsAg-positive patients with DLBCL undergoing rituximab-based treatment, who received prophylactic treatment with or without lamivudine, were retrospectively analyzed. From January 2003 to December 2009, there were 50 patients enrolled in the study, among of which 30 received the prophylactic treatment of lamivudine and 20 without prophylactic treatment of lamivudine. Among of the 50 patients, seven patients received further rituximab maintenance, once every 3 months for 2 years. Compared with lamivudine treatment group, it showed that there was significantly higher prevalence of HBV reactivation (60.0% vs 13.3%, P = .001), severe hepatitis (45.0% vs 6.7%, P = .004), and mortality (25.0% vs 3.3%, P = .032) in non-lamivudine prophylactic group; however, there was no statistically significant difference in the HBV DNA levels at reactivation (3.94 × 10 vs 8.30 × 10 copies/ml, P = .47) and the time from first dose of rituximab to HBV reactivation(207 vs 386 days, P = .28). For patients undergoing further rituximab maintanence treatment, the prevalence and mortality of HBV reactivation were 71.4 and 28.6%, respectively. The prevalence and mortality of HBV reactivation are 66.7% vs 75.0% ( P = 1.00) and 0 vs 50.0% ( P = .43) in lamivudine prophylactic and non-lamivudine prophylactic groups, respectively. The effect of lamivudine prophylaxis on preventing HBV reactivation was found to be less in patients undergoing longer duration of rituximab treatment. A longer duration of rituximab treatment contributed to higher morbidity and mortality of HBV reactivation in HbsAg-positive patients with DLBCL. Further study is warranted for the optimal management of hepatitis caused by HBV reactivation [ABSTRACT FROM AUTHOR]

Patients with newly diagnosed acute lymphoblastic leukemia (ALL) at a single institution were analyzed retrospectively. From 2006 to 2010, 47 patients were treated using the MRC UKALLXII/ECOG E2993 protocol. Prior to July 2005, 40 patients had been treated with the JALSG ALL 87 protocol. A complete remission (CR) rate of 91.5% was achieved with the E2993 protocol, which was not significantly higher than the 80% achieved using JALSG (P > 0.05). The median duration of CR in months was 19 for all patients treated with the MRC UKALLXII/ECOG E2993 protocol. Ph+ patients showed a median CR duration of 11.5 months, while Ph- patients had a significantly longer CR duration of 19 months (P = 0.019). Further, Ph- patients at standard risk (stratified on the basis of age and white blood cell count at diagnosis) had a CR duration of 21 months, which was significantly longer than the 12-month CR duration for the ten Ph- patients at high risk (P = 0.001). Significant differences were found in the 2-year event-free survival and overall survival rates between the MRC UKALLXII/ECOG E2993 and JALSG ALL 87 groups in the following three cohorts: all patients (P = 0.009 and 0.022, respectively), Ph- patients (P = 0.009 and 0.018, respectively), and standard-risk patients (P = 0.014 and 0.007, respectively). The overall mortality rate for induction therapy in the MRC UKALLXII/ECOG E2993 group was 2.1% (1 of 47 patients). One or more instances of grade IV myelosuppression occurred during induction therapy. Among the non-hematological toxicities, alopecia and elevated ALT and AST levels were the most common. The levels of ALT and AST could be reduced to less than twofold the normal values within 1-2 weeks. The data indicate that the MRC UKALLXII/ECOG E2993 regimen is well tolerated in Chinese adults with ALL and can improve survival compared with the JALSG ALL 87 protocol. Risk stratification at diagnosis based on age and WBC count is suitable for adults with ALL, and it is necessary to adopt different strategies as determined by diagnostic results. Lastly, Ph+ patients have an extremely poor prognosis. [ABSTRACT FROM AUTHOR]

significant proportion of patients with nasopharyngeal carcinoma (NPC) will develop regional relapse or distant metastasis after treatment. So, to find valuable prognostic factors becomes very important. To elucidate the expression of ezrin in NPC and its correlation with patients' clinicopathologic characteristics, time to progression, and overall survival, immunohistochemistry stains for ezrin were applied to 200 tissue specimens of NPC. Ezrin expression had no significant correlation with sex, age, primary tumor stage (T), Epstein-Barr virus (EBV) VCA-IgA antibody, EBV EA-IgA antibody, and EBV DNA copy except primary nodal status (N; p = .032). Increased ezrin expression was significantly related to higher lymph nodal metastatic rate ( p < .004). Among ezrin , ezrin , and ezrin groups, there was a significant difference for median time to progression (not reached vs. 63.2 months vs. 46 months, P < .001) and median overall survival (100.7 months vs. 80.8 months vs. 70.6 months, P < .001). Ezrin expression status was an independent prognostic factor in multivariate (Cox) analysis. Ezrin, which was significantly correlated to prognosis of disease, may be involved in the tumorigenesis, progression, and invasion of NPC. Thus, our data offer the possibility of future therapeutic targets. [ABSTRACT FROM AUTHOR]
