Objective To investigate the expression of miR-200b in lung cancer and its relationship with clinicopathological features of lung cancer.Methods The specimens of lung tumor tissue and adjacent normal lung tissue of 36 cases of lung cancer who received surgical treatment in our department were collected,and then quantitative real time PCR (qRT-PCR) was applied to determine the expression of miR-200b in lung cancer tissue and adjacent normal lung tissue.Results The expression of miR-200b in lung cancer was significantly lower than adjacent normal lung tissue (P =0.000),and in small cell lung cancer was also significantly lower than adenocarcinoma and squamous cell carcinoma (0.13 ± 0.09 vs.0.64 ± 0.33,0.75 ± 0.30) (P =0.005 and P =0.001).The expression of miR-200b in patients with positive lymph nodes,advanced stage of lung cancer and in smokers were significantly lower than those with negative lymph nodes,early stage of lung cancer and in non-smokers,respectively (0.52 ± 0.29 vs.0.87 ± 0.35,0.46 ±0.25 vs.0.90 ±0.32,0.52 ±0.27 vs.0.90 ±0.39) (P =0.004,P =0.000 and P =0.015).Conclusions Low expression of miR-200b may participate in the occurrence and progression of lung cancer,especially in small cell lung cancer,and correlates with the metastasis of lung cancer.The down-regulated expression of miR-200b may be induced by smoking.Thus,miR-200b perhaps is a new target for the treatment of lung cancer.

Objective: To investigate the clinical status of lymphoid tissue neoplasms patients with bacteria bloodstream infections, bacteriology and drug susceptibility results, and provide the basis for rational clinical anti-infection option. Methods: A retrospectively analysis of clinical data and bacterial susceptibility test results of patients with bacteria bloodstream infections from September 2010 to December 2014 was conducted. Results: A total of 134 cases including 107 patients with bloodstream infections were enrolled. 84 cases were male, 50 cases were female, the median age was 31 (12-71) years old. 112 cases were agranulocytosis, and 106 cases were severe agranulocytosis (ANC<0.1×10⁹/L) . 27 cases underwent hematopoietic stem cell transplantation, 100 cases received chemotherapy[33 cases with VD (I) CP±L (vincristine+daunorubicin/idarubicin + cyclophosphamide + prednison±asparaginasum) induction chemotherapy, 41 cases with intensive chemotherapy of Hyper-CVAD/MA or MA (mitoxantrone+cytarabine) , 26 cases with other chemotherapy regimens], and 7 cases were infected without chemotherapy. 10 patients discharged from hospital owing to treatment abandoning, 120 cases were cured through anti-infective therapy, 2 patients died of bacteria bloodstream infections, 1 patient died of sudden cardiac, and 1 patient died of GVHD after allogenic hematopoietic stem cell transplantation. A total of 144 strains were isolated, including 108 strains (75.0%) of Gram-negative bacteria and 36 strains (25.0%) of Gram-positive cocci. The susceptibility of Gram-negative bacteria to the carbapenems was 98.00%, and the adjustment treatment rate of carbapenems was 3.0%. The susceptibility of Gram-negative bacteria to the other antibiotics was 60.30%, and the adjustment treatment rate was 90.5%. The susceptibility of Grampositive cocci to the carbapenems was 49.3%, and to glycopeptides and linezolid was 100.0%. Comparing all patients’empirical use of antimicrobial agents with the drugs susceptibility results of blood cultures, 80.1% of the patients’initial drug selection was sensitive. Conclusion The lymphoid neoplasms patients experienced bacteria bloodstream infections most often after receiving the chemotherapy regimens of treating acute lymphoblastic leukemia. The majority type of bacteria was Gram-negative bacteria. Drug susceptibility test showed that susceptibility of Gram-negative bacteria to the carbapenems was the highest, and the treatment adjustment rate was obviously lower. The susceptibility of Gram-positive cocci to glycopeptides and linezolid was high, and which could be applied to the patients with Gram-positive cocci sepsis on basis of susceptibility results in general.

Objective: To investigate the curative effect of hairy cell leukemia by clatabine. Methods: The clinical data of 24 patients with hairy cell leukemia treated by cladribine from November 2006 to October 2017 were analyzed retrospectively, then the curative effect and adverse drug reaction were analyzed. Results: ① A total of 24 patients including 22 male and 2 female, and the median age was 49.5 years (range 33 to 76) at diagnosis. There were 20 patients with of splenomegaly (4 patients with mild splenomegaly, 4 moderate splenomegaly, and 12 massive splenomegaly), 3 patients with enlargement of lymph nodes, and 1 patients who had undergone splenectomy. Five patients were pancytopenia, 15 were cytopenia in 2 lineages, and 4 patients were cytopenia only in one lineage. The median ratio of HCL cells detected by flow cytometry in bone marrow was 21.79% (0.69%-68.96%). BRAF mutation was detected in 15 patients by first generation or next generation sequencing technology. ② Among 24 patients, 20 were treated with cladribine alone (one course in 19 patients, 2 courses in 1 patient), and 4 patients were treated with cladribine combined with rituximab (one course in 3 patients, 2 courses in 1 patient). Excepting 5 patients whose follow-up time was not reaching 6 months, 19 patients were evaluated for efficacy in 6-12 months after treatment: 9 patients obtained CR, 9 obtained unconfirmed CR (Cru), the other 1 obtained PR, the CR/CRu rate was 94.7%, the overall response rate (ORR) was 100.0%. ③ All the 24 patients appeared 2-4 grade hematological adverse reactions after cladribine treatment, which were mainly grade 3/4 neutropenia (66.67%) and grade 3/4 thrombocytopenia (29.2%). All the adverse reactions were controlled or recovered spontaneously. ④ After the median follow-up time of 15 (3-133) months, no progression, recurrence or death occurred in the patients. Both median OS and PFS were not reached. Conclusion This study suggests that treatment of HCL with cladribine has high response rate, controllable adverse reactions and the good prognosis.

Objective: To evaluate the efficacy and long-term outcome of a combined protocol for multiple myeloma (MM) , including induction therapy, autologous hematopoietic stem cell transplantation (ASCT) and consolidation and maintenance therapy. Methods: Clinical records of 144 patients with MM from January 1, 2005 to February 1, 2016 were retrospectively analyzed. Results: The overall response rate (ORR) after ASCT was 100.0%, in which the complete remission (CR) was 64.1% and the best treatment response rate of superior to PR was 89.4%. During a median follow-up of 47 months, patients with an overall survival (OS) and progression free survival (PFS) was 120.9 and 56.9 months respectively. 5y-OS (73.7±4.7) %, 7y-OS (60.5±6.3) %; 3y-PFS (69.2±4.2) %, 5y-PFS (47.8±5.3) %. The median OS and PFS between the first line transplantation group and salvage transplantation group were 120.9 months vs 50.1 months and 60.2 months vs 16.7 months (all P=0.000). In 127 patients with R-ISS staging, the median survival of Ⅰ, Ⅱ, Ⅲ stage was 120.9 months (n=43) , 88.4 months (n=64) , 35.6 months (n=20) , respectively (P=0.000). For subgroup analysis of survival in early and late ASCT, the median OS of patients with R-ISS stage Ⅲ (35.6 months vs 15.8 months, P=0.031) and the median PFS of two groups (phase Ⅰ: 72.1 months vs 18.9 months, P=0.000; Ⅱ: 53.4 months vs 16.7 months, P=0.012; Ⅲ: 28.5 months vs 5.9 months, P=0.001) were different. Multivariate analysis showed that only R-ISS and the degree of remission before transplantation had impact on OS (HR=8.486, 95% CI 2.549-28.255, P=0.003) and PFS (HR=2.412, 95% CI 1.364-4.266, P=0.002) , respectively. Conclusion The combined protocol containing ASCT is effective for MM patients, improving remission rate and remission depth, prolonging PFS and OS. First line transplantation could significantly prolong the OS and PFS as compared with salvage transplantation. R-ISS and pre-transplantation remission depth are prognostic factors for survival.

Objective: To assess the feasibility and prognostic value of the minimal residual disease (MRD) evaluated by multiparameter flow cytometry (MFC) in the newly diagnosed multiple myeloma (MM) patients of China. Methods: Clinical data of 106 consecutively newly diagnosed MM patients with MRD data were retrospectively analyzed in a single center in China from June 2013 to June 2015. Results: ① Of 106 patients, 48 (45.3%) achieved MRD negativity. The median time to MRD-negative was 3 months. More patients undergoing autologous stem cell transplantation (ASCT) achieved MRD negativity compared with non-ASCT patients (62.2% vs 36.2%, χ²=6.536, P=0.011). ② Of 48 patients in complete remission (CR), 7 (14.6%) was MRD positive, 5 of them showed disease progression (PD) during the follow-up, and 3 died. The median progression free survival (PFS) was 19 months, and the median overall survival (OS) was 28 months, both were significantly shorter than the CR patients with MRD-negative (P<0.05). ③At a median follow-up of 38 months, MRD-negative patients showed significantly superior outcomes compared with MRD positive ones, the PFS was not reach versus 17 months and the OS was not reach for both (P<0.001). Patients were grouped into 4 categories according to their MRD levels: 1% or higher, 0.1% to less than 1%, 0.01% to less than 0.1%, or negative. It showed that the outcomes (PFS and OS) tended to be improved along with the tumor depletion. ④ Multivariate prognostic analysis showed that MRD was a powerful independent prognostic factor for PFS[HR=0.133 (95% CI 0.062-0.288) , P<0.001] and OS[HR=0.156 (95% CI 0.050-0.484) , P=0.001]. According to MRD and cytogenetics, the patients were classified into 4 groups. High risk patients with MRD negative presented a significantly better outcome than high risk patients with MRD-positive, and a similar one to the standard risk patients with MRD-negative. Conclusions MRD negativity by MFC was more popular in MM patients undergoing ASCT. MRD was an independent prognostic factor in MM. And the prognosis of MM patients can be stratified according to the level of MRD. MRD-negative patients with high risk cytogenetics presented a similar outcome to the standard risk ones. MRD by MFC should therefore be considered more widely applied in the clinic.

OBJECTIVETo investigate the outcomes of autologous stem cell transplantation (ASCT) for patients with aggressive peripheral T-cell lymphoma (PTCLs) in advanced stage.

METHODSThe clinical data of 25 patients in complete remission (CR) with aggressive PTCLs received ASCT from May 1997 to June 2013 were retrospectively analyzed.

RESULTS① Of the 25 cases, 16 were unspecified PTCL (PTCL-U), 4 with angioimmunoblastic T cell lymphoma (AITL), 3 with anaplastic large cell lymphoma (ALCL) and 2 with hepatosplenic T cell lymphoma (HSTL), with a median age of 30(12-54) years old. Ratio of male to female is 16∶9. The distribution of stages was 8 cases with stage Ⅲ and 17 patients with stage Ⅳ. Nine patients presented with bone marrow involvement. Before ASCT, 18 patients were in CR1 and 7 patients were in CR2. ②Two patients with HSTL in stage ⅣB and IPI score 4/5 in CR1 relapsed and died within 12 months after ASCT. At a median follow-up of 38 (range 14-110) months, the estimated 3-year probability of PFS and OS for the other 23 patients was (63.1 ± 10.5)% and (71.8 ± 9.9)%, respectively. The patients in first CR had a better survival than the patients in second CR. The 3-year probability of PFS were (74.9 ± 11.0)% vs (33.3 ± 19.2)% (P=0.092) and OS were (80.2 ± 10.4)% vs (50.0 ± 20.4)% (P=0.043), respectively. The 3-year probability of PFS and OS were (40.0 ± 17.4)% and (53.3 ± 17.3)% in bone marrow involvement patients and the corresponding figure were (77.9 ± 11.3)% and (84.4 ± 10.2)% in non- bone marrow involvement patients.

CONCLUSIONASCT could improve the survival of aggressive PTCLs. Non CR1 status and bone marrow involvement had negative influence on OS in patients with aggressive PTCLs treated by ASCT. The prognosis was very poor in patients with HSTL and satisfactory regimens should be investigated.

OBJECTIVETo assess the efficacy of dose-intensive immunochemotherapy with or without autologous hematopoietic stem cell transplantation (ASCT) for newly diagnosed young patients with medium/high risk diffuse large B-cell lymphoma (DLBCL).

METHODSThe retrospective study was performed in 29 cases of young patients (≤ 60 years) with newly diagnosed DLBCL and an age-adjusted International Prognostic Index (aaIPI) score of 2 or 3. All of them were treated with dose-intensive regimens (DA-EPOCH or Hyper-CVAD/MA) combined with Rituximab and some were consolidated with first-line ASCT. The efficacy and the potential predictors were evaluated.

RESULTSThe median age of 29 patients was 43 years old. Of them, 12 patients were consolidated with high-dose chemotherapy and ASCT. The complete remission (CR) rate was 69%, the partial remission (PR) rate 21% and the overall response rate 90%. After a median follow-up of 14 months, the estimated progression-free survival (PFS) and overall survival (OS) at two years were 64% and 70%, respectively. The median PFS and OS were significantly longer in CR patients than that in PR patients (P=0.015 and 0.061, respectively). Two patients achieved PR after induction therapy converted to CR after ASCT and were in continuous CR after follow-up above three years. In multivariate analysis, only bone marrow involvement (BMI) at diagnosis had an adverse influence in PFS (P=0.009), but not in OS. Based on whether there was BMI or not and the extent of BMI at diagnosis, the patients were divided into three groups as BM-0 (without BMI), BM-1 (the extent of BMI ≤ 10%) and BM-2 (the extent of BMI>10%). Patients in BM-2 group had significantly shorter PFS and OS than those in BM-0 and BM-1 groups (P=0.001 and 0.045, respectively). In multivariate analysis, the extent of BMI>10% was the independent poor prognostic factor for PFS and CNS relapse or prognosis.

CONCLUSIONDose-intensive immunochemotherapy followed by ASCT or not has significant effect on efficacy of first-line treatment for young and untreated patients with medium/high risk DLBCL. The extent of BMI>10% at diagnosis is an independent risk factor associated with poor PFS and increased CNS relapse or progression.

OBJECTIVETo investigate the treatment outcomes of autologous stem cell transplantation (ASCT) as first-line treatment in patients with high risk lymphoblastic lymphoma (LBL) and compare the effect of different induction regimen on prognosis.

METHODSThirty LBL patients in complete remission received ASCT from 1996 to 2012 in our hospital were retrospectively analyzed.

RESULTS(1)Of the 30 patients, 25 were T-LBL and 5 B-LBL with a median age of 19(7-53) years old. Ratio of male to female is 23:7. Fourteen (46.7%) patients presented with bulky mediastinal masses and 15(50.0%) with bone marrow involvement. The distribution of stages was 2(6.7%), 5(16.7%) and 23 (76.6%)patients with stages II, III, and IV, respectively. The distribution according to age-adjusted international prognostic index (aaIPI) was 5(16.7%) patients in 1 score, 14(46.6%) in 2 scores and 11(36.7%) in 3 scores. (2)At a median follow-up of 32(range, 10-171) months, 17 patients were alive and 13 relapsed and died from LBL after ASCT. The estimated 5-year probability of DFS and OS was (50.4±10.7) % and (53.9 ±10.2)% for all the patients. (3)According to the treatment regimens before ASCT, the patients were divided into NHL-type group (n=12) and ALL-type group (n=18). In NHL-type group, 9 patients relapsed and died, the estimated 5-year probability of DFS and OS was (22.2 ±12.8) % and (33.3 ±13.6) %, respectively. Median DFS and OS time were 24 months and 36 months. In ALL-type group, 4 patients relapsed and died from lymphoma, the estimated 5-year probability of DFS and OS was (77.8 ± 9.8) % and (77.8 ± 9.8) %, respectively. Median DFS and OS time were not reached. For DFS and OS, ALL-type group were better than that of NHL-type group and the difference was significant (P=0.022 and P=0.049).

CONCLUSIONThe results showed that complete remission with intensive first-line ALL-type regimens and followed by ASCT consolidation may significantly improve long-term outcome for high risk LBL patients.
