Chinese guidelines for treatment of adult primary immune thrombocytopenia.

Primary immune thrombocytopenia (ITP) is a bleeding disorder commonly encountered in clinical practice. The International Working Group (IWG) on ITP has published several landmark papers on terminology, definitions, outcome criteria, bleeding assessment, diagnosis, and management of ITP. The Chinese consensus reports for diagnosis and management of adult ITP have been updated to the 4th edition. Based on current consensus positions and new emerging clinical evidence, the thrombosis and hemostasis group of the Chinese Society of Hematology issued Chinese guidelines for management of adult ITP, which aim to provide evidence-based recommendations for clinical decision making.

Clinical analysis of 1629 newly diagnosed malignant lymphomas in current residents of Sichuan province, China.

Previous studies in other provinces of China (Beijing, Xinjiang, Shanxi, Jiangxi, Shanghai, Guangdong, and Taiwan) suggest that the distributions of lymphoma subtypes differ compared with Western populations. In order to evaluate the characteristics of malignant lymphoma in Sichuan, China, we analyzed case series data from incident lymphoma patients diagnosed in 2008 from three hospitals, including a total of 1629 cases and including only current residents of Sichuan. The median age of diagnosis for cases was 54 years, with a higher proportion of male cases compared with female cases. The most commonly diagnosed subtypes included diffuse large B-cell lymphoma (40.4%), NK/T-cell lymphoma (NKTCL; 11.8%), mixed cellularity Hodgkin lymphoma (7.0%), mantle cell lymphoma (4.8%), and marginal zone B-cell lymphoma (3.9%). Differences in demographic characteristics between Hodgkin lymphoma (HL) and non-Hodgkin lymphoma (NHL) cases were apparent for median age at diagnosis (HL: 34 years; NHL: 57 years), and NHLs accounted for nearly all (99.3%) of the 931 cases of extranodal lymphoma. These findings indicate a higher proportion of NKTCL cases and a lower proportion of follicular lymphoma cases (2.3%) in these hospitals in Sichuan, relative to reports from some other provinces within China (e.g., Shanghai and Shanxi) and the USA.

Meta analysis of treatment for stage IE~IIE extranodal natural killer /T cell lymphomas in China.

OBJECTIVE: To evaluate early treatment for extranodal natural killer/T cell lymphoma (ENK/TCL) in China and provide reference for clinical treatment of these patients. METHODS: Computer-based retrieval was performed in PubMed, CNKI, CBM, VIP and WanFang Data to search for randomized controlled trials (RCTs) of treatment for early ENK/TCL, and a meta-analysis was conducted with RevMan 5.0 software. RESULTS: A total of 11 RCTs, including 871 patients, were selected, of which the first radiotherapy had a higher complete response (CR) than the first chemotherapy [OR=14.16, 95%CI (8.68, 23.10), P<0.00001] and CR was not different between combined treatment group and radiotherapy group [OR=1.86, 95%CI (0.47, 3.58), P=0.61], but long-term survival rate was higher with combined treatment[OR=1.88, 95%CI (1.09, 3.19), P=0.02]. No difference in survival rate was observed between radio-chemotherapy and chemo-radiotherapy groups [OR=1.11, 95%CI (0.73, 1.69), P=0.63]. CONCLUSIONS: Radiotherapy is of great significance in the treatment of early ENK/TCL, but combined therapy could further enhance long-term survival rate of patients. This conclusion still requires further confirmation using RCTs with high quality and large sample size.

[Determination of serum granulocyte colony-stimulating factor level in patients with chronic idiopathic neutropenia and its significance].

To investigate the serum granulocyte colony-stimulating factor (G-CSF) level in patients with chronic idiopathic neutropenia (CIN) and analyze its clinical significance. By the use of G-CSF-specific enzyme-linked immunosorbent assay (ELISA), the serum levels of G-CSF were determined in 40 cases with chronic CIN, 40 cases with systemic lupus erythematosus (SLE) complicated neutropenia and 40 healthy volunteer (normal control). Results showed that serum G-CSF was positive in 11 normal controls and in 10 cases with SLE, and the G-CSF levels were (27.34 +/- 8.00) ng/L and (26.76 +/- 7.26) ng/L, respectively. Serum G-CSF in 27 cases with CIN was positive, the level was (134.04 +/- 89.29) ng/L, which was higher than that in the normal controls and the cases with SLE (P < 0.01). It was concluded that an obstacle to utilization of G-CSF could be existed in the patients with CIN.
