ABSTRACT

Post-transplantation cyclophosphamide (PT-Cy) alone or in combination with other immunosuppressive drugs has emerged as a promising strategy in the setting of allogeneic hematopoietic stem cell transplantation. Improved survival rate was reported in lymphoid malignancies following PT-Cy strategy compared with myeloid disease in non-myeloablative bone marrow transplant setting. Thus, we aimed to evaluate the safety and efficacy of PT-Cy combined with cyclosporine as graft-versus-host disease (GVHD) prophylaxis after myeloablative conditioning and T cell-replete peripheral stem cell transplantation in lymphoid malignancies. This single-arm phase II clinical trial (NCT01435447) involving 31 adult patients was conducted from January 2013 to June 2018. The donor-type neutrophil engraftment rate was 100%, and the overall incidence of grade II to IV and grade III to IV acute GVHD was 39% and 24%, respectively. The cumulative incidence rates of chronic GVHD (35%), including moderate to severe forms (10%), were reduced compared with those of the historical group (P = 0.03 and P = 0.04, respectively). With a median follow-up of 18 months, the estimated 2-year overall and event-free survival was 64.8% (95% confidence interval: 47.8%-86.7%) and 58.4% (95% CI: 41.9%-81.7%), respectively. The 2-year cumulative incidence rate of relapse was 19.5% (95% CI: 9.0%-35.8%), whereas the non-relapse mortality rate was 21.8% (95% CI: 11.3%-38.1%). These results demonstrated the feasibility of PT-Cy as GVHD prophylaxis in this clinical setting. This strategy could significantly reduce the incidence of chronic GVHD and its moderate to severe forms but not of acute GVHD and results in similar survival outcomes compared with the historical group. A prospective study with additional patients is warranted to confirm the role of PT-Cy in lymphoid malignancy.

ABSTRACT

Objective:To summarize and analyze the clinical data of Chinese patients with colony-stimulating factor 1 receptor (CSF1R)-related leukoencephalopathy, and clarify the phenotypic and genetic characteristics of Chinese patients.Methods:Medical history of patients with CSF1R-related leukoencephalopathy diagnosed from April 1, 2018 to January 31, 2021 in the department of neurology of 22 hospitals in China was collected, and scores of Mini-Mental State Examination (MMSE), Montreal Cognitive Assessment Scale (MoCA), magnetic resonance severity scale were evaluated. Group comparison was performed between male and female patients.Results:A total of 62 patients were included, and the male-female ratio was 1∶1.95. The age of onset was (40.35±8.42) years. Cognitive impairment (82.3%, 51/62) and motor symptoms (77.4%,48/62) were the most common symptoms. The MMSE and MoCA scores were 18.79±7.16 and 13.96±7.23, respectively, and the scores of two scales in male patients (22.06±5.31 and 18.08±5.60) were significantly higher than those in females (15.53±7.41 , t=2.954, P=0.006; 10.15±6.26, t=3.328 , P=0.003). The most common radiographic feature was bilateral asymmetric white matter changes (100.0%), and the magnetic resonance imaging severity scale score was 27.42±11.40, while the white matter lesion score of females (22.94±8.39) was significantly higher than that of males (17.62±8.74 , t=-2.221, P<0.05). A total of 36 CSF1R gene mutations were found in this study, among which c.2381T>C/p.I794T was the hotspot mutation that carried by 17.9% (10/56) of the probands. Conclusions:The core phenotypic characteristics of CSF1R-related leukoencephalopathy in China are progressive motor and cognitive impairment, with bilateral asymmetrical white matter changes. In addition, there exist gender differences clinically, with severer cognitive impairment and imaging changes in female patients. Thirty-six CSF1R gene mutations were found in this study, and c.2381T>C/p. I794T was the hotspot mutation.

ABSTRACT

Objective:To explore the posture control of professional dancers. Methods:From April to August, 2017, 21 professional dancers from an international famous club were as experimental group. Matching the height and age, etc., 21 medical workers were recruited as control group. They were tested with Tetrax Balance Evaluation System, and assessed with Trunk Stability Test (TST) and the Star Excursion Balance Test (SEBT). Results:There was no significant difference on fail-time of TST and maximum distance of SEBT between right and left sides in both groups. The fail-time of TST was less in the experimental group than in the control group (t =-2.667, P < 0.05), as well as the maximum distance of SEBT (t = -3.991, P < 0.001). There was no significant difference on falling index between both groups (t = 1.810, P > 0.05). Conclusion:Compared with medical workers, professional dancers do better in static balance, but worse in dynamic balance. Their performance of posture control is almost the same as the others.

ABSTRACT

Invasive fungal disease (IFD) is a major infectious complication in patients with hematological malignancies. In this study, we examined 4889 courses of chemotherapy in patients with hematological diseases to establish a training dataset (n = 3500) by simple random sampling to develop a weighted risk score for proven or probable IFD through multivariate regression, which included the following variables: male patients, induction chemotherapy for newly diagnosed or relapsed disease, neutropenia, neutropenia longer than 10 days, hypoalbuminemia, central-venous catheter, and history of IFD. The patients were classified into three groups, which had low (0-10, ~1.2%), intermediate (11-15, 6.4%), and high risk ( > 15, 17.5%) of IFD. In the validation set (n = 1389), the IFD incidences of the groups were ~1.4%, 5.0%, and 21.4%. In addition, we demonstrated that antifungal prophylaxis offered no benefits in low-risk patients, whereas benefits were documented in intermediate (2.1% vs. 6.6%, P = 0.007) and high-risk patients (8.4% vs. 23.3%, P = 0.007). To make the risk score applicable for clinical settings, a pre-chemo risk score that deleted all unpredictable factors before chemotherapy was established, and it confirmed that anti-fungal prophylaxis was beneficial in patients with intermediate and high risk of IFD. In conclusion, an objective, weighted risk score for IFD was developed, and it may be useful in guiding antifungal prophylaxis.

ABSTRACT

Objective To observe the effec t and safety of posaconzole in prophylactic antifungal treatment of high-risk patients with hematological malignancies. Methods The effect of posaconzole on prevention of invasive fungal disease (IFD) during chemotherapy in 102 patients with hematological malignancies in Shanghai Ruijin Hospital from February 2014 to April 2017 were analyzed retrospectively. The correlation analysis was carried out by Spearman analysis. Results A total of 102 patients were included, and only 2 (1.96%) patients had IFD. 2 patients died because of development of hematological malignancies. 11 (10.8%) patients had to discontinuation of posaconzole because of sever adverse events. Two patients with IFD and 1 case of undiagnosed IFD had to discontinue posaconzole. The total rate of discontinuation was 13.7 % (14/102). There was no correlation between the time of using pothiazol and the time of hospitalization (rs= -0.02, P= 0.853) and the time of neutrophilic deficiency (rs= 0.167, P= 0.113), but the time of hospitalization was positively correlated with the time of neutrophilic deficiency (rs = 0.448, P=0.000). Conclusion Posaconzole could effectively and safely prevent IFD in patients with hematological malignancies.

ABSTRACT

Objective@#To investigate the pathogen spectrum distribution and drug resistance of febrile neutropenic patients with hematological diseases in Shanghai.@*Methods@#A retrospective study was conducted on the clinical isolates from the febrile neutropenic patients hospitalized in the departments of hematology in 12 general hospitals in Shanghai from January 2012 to December 2014. The drug susceptibility test was carried out by Kirby-Bauer method. WHONET 5.6 software was used to analyze pathogenic bacteria and drug susceptibility data.@*Results@#A total of 1 260 clinical isolates were collected from the febrile neutropenic patients. Gram-positive bacteria accounted for 33.3% and Gram-negative bacteria accounted for 66.7%. Klebsiella pneumoniae (12.5%) , Stenotrophomonas maltophilia (9.5%) , Escherichia coli (9.1%) , Pseudomonas aeruginosa (8.7%) , Acinetobacter baumannii (6.6%) , Staphylococcus aureus (5.6%) and Enterococcus faecium (5.0%) were ranked in the first 7 of all pathogens. In the respiratory tract secretions specimens, non-fermented strains accounted for 56.2%. Stenotrophomonas maltophilia accounted for 15.2%. Enterobacteriaceae and coagulase-negative Staphylococci accounted for 42.3% (104/246) and 32.6% (85/246) respectively in blood samples. Enterobacteriaceae and Enterococcus bacteria accounted for 39.4% (76/193) and 28.5% (55/193) respectively in pus specimens. The detection rates of methicillin resistant Staphylococcus aureus (MRSA) and methicillin resistant coagulase negative Staphylococci (MRCNS) were 54.3% and 82.5%, respectively. Staphylococcus bacterial strain was not found to be resistant to linezolid, vancomycin and teicoplanin. The detection rate of Enterococcus vancomycin-resistant strains was 8.9%. Enterococcus was not detected resistance to oxazolidinone strains. Enterobacteriaceae bacteria were highly sensitive to carbapenems. The resistance rate of Pseudomonas aeruginosa to imipenem and meropenem was 34.1% and 15.8%, respectively. Stenotrophomonas maltophilia was more sensitive to minocycline hydrochloride, levofloxacin and sulfamethoxazole. The resistance rate of Acinetobacter baumannii only to cefoperazone-sulbactam was less than 10.0%. The antibiotic resistance rate of Klebsiella pneumoniae, Stenotrophomonas maltophilia, Pseudomonas aeruginosa and Acinetobacter baumanii to most of common antibiotics was lower than that of the CHINET surveillance.@*Conclusions@#The pathogenic strain distribution in common infection sites of febrile neutropenic patients was characterized. Bacterial resistance surveillance was better than the CHINET nationwide large sample surveillance in China.

ABSTRACT

<p><b>OBJECTIVE</b>To explore the clinical effects of Dynesys system combined with posterior lumbar interbody fusion (PLIF) in treating multiple lumbar degenerative disease.</p><p><b>METHODS</b>The clinical data of 46 patients with multiple lumbar degenerative diseases treated by Dynesys system combined with PLIF from September 2010 to May 2013 were retrospectively analyzed. There were 17 males and 29 females, aged from 38 to 68 years old with an average of (56.38±11.63) years. Operation section was in L2-L5 of 16 patients (6 with fusion of L4,5 and 10 with fusion of L4,5,L5S1) and in L3-S1 of 30 patients (11 with fusion of L5S1 and 19 with fusion of L4,5,L5S1). Patients were followed up for three times: postoperative 3 months, 1 year and final follow-up. Visual analogue scale (VAS) and Oswestry Disability Index (ODI) were used to assess clinical symptoms preoperatively and postoperatively. All patients underwent flexion/extension radiographs examinations before surgery and at final follow-up. Range of motion (ROM) and disc height index (DHI) were recorded.</p><p><b>RESULTS</b>All patients were followed up from 16 to 48 months with the mean of (23.23±7.34) months. At third follow-up after operation, ODI and VAS of lumbago and leg pain were significant improved than that of preoperative (P<0.01). DHI of fusion segment was significantly increased than that of preoperative (P<0.05). There was no significant difference in adjacent non-fusion segment between preoperative and postoperative (P>0.05). Postoperative ROM of fusion and non-fusion segments were obviously decreased than that of preoperative. There was no significant difference in ROM of upper adjacent non-fusion segment between 3 months and 1 year after operation (P>0.05), but at final follow-up, the ROM was increased (P<0.05).</p><p><b>CONCLUSION</b>The preliminary clinical results of the Dynesys system combined with PLIF in the treatment of multiple lumbar degenerative diseases are satisfactory. It can be determined in fusion or non-fusion according to the individual needs and can reserve the some intervertebral motion, prevent the early degeneration of adjacent segments. However, its long-term clinical efficacy should be verified with long time.</p>

ABSTRACT

<p><b>OBJECTIVE</b>To explore the prognostic significance of Ph-positive and/or BCR-ABL positive acute lymphoblastic leukemia (Ph⁺ ALL).</p><p><b>METHODS</b>A retrospective analysis of 72 patients with Ph⁺ ALL to probe prognostic factors including sex, age, high white cell counts at diagnosis, additional chromosome abnormality, BCR-ABL transcripts type, imatinib based therapy, allo-HSCT and complete remission (CR) after one-course induction on the outcomes of Ph⁺ALL patients.</p><p><b>RESULTS</b>Of 72 patients with median age 40.5 (13-68) years, 38 patients received imatinib plus chemotherapy. With median follow-up of 11 (0.2-96) months, total CR rate in patients receiving imatinib plus chemotherapy was higher than of patients receiving chemotherapy only (97.4% vs 62.3%, P=0.019). High white blood counts at diagnosis or additional chromosome abnormality had no effects on CR rate. 2-year overall survival (OS) and disease free survival (DFS) in imatinib plus chemotherapy group were (28.9±7.4) % and (25±7.4) %, respectively, which were higher than those in chemotherapy group (P<0.001). OS rate in HSCT group was significantly higher than that in non-HSCT group[ (61.1±11.5) % vs (5.6±3.1) %, P<0.001]. Multivariate prognostic analysis for OS showed that imatinib-based therapy [RR=0.413 (95% CI 0.237-0.721), P=0.002], allo-HSCT [RR=0.175 (95% CI 0.075-0.389), P=0.000] and CR after one-course induction [RR=0.429 (95% CI 0.245-0.750), P=0.003] were of importance for survival.</p><p><b>CONCLUSION</b>allo-HSCT was an optimal choice for Ph⁺ALL patients. Imatinib-based therapy could increase CR rate, maintain CR duration and decrease relapse, resulting in more chance of HSCT. Imatinib improved the outcomes of Ph⁺ALL patients who were not eligible for HSCT.</p>

ABSTRACT

Background and purpose: High-dose chemotherapy followed by autologous stem cell transplantation (auto-HSCT) is considered as the ifrst line treatment for patients with relapse/refractory lymphoma after conventional chemotherapy. However, most of these patients still relapse the second time. The purpose of this study was to analyze the efifcacy of the consolidation chemotherapy after autologous stem cell transplantation (HSCT) refractory/relapse lymphoma in high risk. Methods:A total of 38 patients with relapsed/refractory lymphoma including Hodgkin lymphoma (HL) and non-Hodgkin lymphoma (NHL) were included, who were underwent auto-HSCT in our transplan-tation department from Jan. 2010 to Dec. 2013. In treatment group, 19 patients received 2 courses of consolidation che-motherapy after auto-HSCT every 2 to 3 months, with the regimen of mini-BEAM or modiifed mini-CBV. Another 19 patients had no chemotherapy after auto-HSCT as control group. Results:The median follow-up duration was 17.2 and 7.5 months in the treatment and control group respectively. The follow-up data demonstrated prolonged progression-free survival (PFS) in the treatment group than the control group [24.7 months vs 7.8 months, P=0.029 under intend-to-treat analysis ITT;24.7 months vs 5.2 months, P=0.01 under per protocol analysis(pp)]. There is also a trend of improved overall survival (OS) in the treatment group (P=0.055, ITT). Conclusion:Consolidation chemotherapy after auto-HSCT for refractory/relapsed lymphoma patients delay the relapse and tend to improve the overall relapse rate.

ABSTRACT

OBJECTIVE@#To explore the clinical effect and safety of internal fixation of steel-wire limited loop in early Achilles tendon rupture.@*METHODS@#Seventy-six patients respectively with early transected and avulsed types of Achilles tendon rupture were selected and treated with internal fixation of steel-wire limited loop. The patients began to take exercise for their lower limbs through continous passive motion as early as possible after surgical repair, and the loops were removed after 3-5 months. Six months later, the condition of complications including Achilles tendon re-rupture, wound fistula, wound infection and skin necrosis, cutaneous sensation in sural nerve dominance region, time back to preinjury work or learning as well as time to physical activities were observed. One year later, the therapeutic effect was evaluated, and the maximum circumferences of bilateral legs and ruptured plane circumferences of Achilles tendon were measured.@*RESULTS@#The wound of all patients healed well, no complications like Achilles tendon re-rupture, wound fistula, wound infection and skin necrosis occured, and the cutaneous sensation in sural nerve dominance region was normal. The mean time back to preinjury work or learning as well as to pysical activities of all patients were respectively 10 and 22 weeks. Seventy out of 76 patients (92.1%) achieved an excellent effect, and 6 (7.9%) good effect. The excellent and good rate came up to 100%. The maximum circumference in the affected leg decreased to 2 mm averagely compared with the offside, while the ruptured plane circumferences of Achilles tendon in the affected side increased to 2.2 mm compared with the offside.@*CONCLUSIONS@#For early Achilles tendon rupture, internal fixation of steel-wire limited loop can recover the ankle function better, return to the preinjury state in the shortest time, and has few complications.

Objective To evaluate the risk factors of developing post-engraftment hemorrhagic cystitis (HC) in patients receiving allogeneic stem cell transplantation (allo-HSCT).Methods Retrospective data was collected from 92 patients with acute leukemia (acute myeloid leukemia 41 and acute lymphoblastic leukemia 51) who underwent allo-HSCT from 2000 to 2010,and the association of pre-transplantation parameters with the incidence of post-engraftment HC was analyzed.Results Forty-three patients had HLA-matched donors and 49 had unrelated donors.Of these patients,25 developed HC at a median of 35 days (day +20 to +65) after allo-HSCT.In the univariate analysis,unrelated donor,gender mismatch (female donor to male recipient),conditioning containing busulfan,graft-versus-host disease (GVHD),prophylaxis with cyclosporine (CSA) + methotrexate (MTX) + mycophenolate mofetil (MMF),use of anti-thymoglobulin (ATG) and development of GVHD were associated with increased incidence of HC.In the multivariate study,gender mismatch (P =0.001),use of ATG (P < 0.001),and GVHD (P =0.007) remain as independent factors for the increased risk of HC.More importantly,with these 3 factors,it is able to classify patients into 4 groups with risk of postengraftment HC at (7.7±4.6) %,(22.9±7.1) %,(48.2±10.5) %,and 100.0 %,respectively.Conclusion This retrospective study identified the gender mismatch,use of ATG in the preparation regimen,and aGVHD as important risk factors to predict the development of post-engraftment HC.Based on these risk factors,it is possible to classify patients into different risk groups for post-engraftment HC.Prospective study with a large cohort of patients is warranted to confirm the findings.Future clinical trial for HC prevention and treatment must be carried out on the intermediate and high-risk patients.

ABSTRACT

Objective To assess the impact of a composite index which combines the prognosis of specific hematologic malignancies and the disease remission state pre-transplant on the efficacy of allogeneic hematopoietic stem cell transplantation.Methods A total of 148 patients who underwent allogeneic hematopoietic stem cell transplantation from Jan,2007 to Feb,2012 in the Blood and Marrow Transplantation Center of Ruijin Hospital were included in this retrospective analysis.According to the composite score,patients were classified into low-risk group (n =17),medium-risk group (n =100) and high-risk group (n =31).The overall survival (OS),event free survival (EFS),treatment related mortality (TRM) and relapse rate (RR) were analyzed.Results Significant difference had been found on OS (76.5 % vs 66.0 % vs 41.9 %,P =0.002),EFS (70.6 % vs 57.0 % vs 32.3 %,P =0.001) and RR (41.9 % vs 27.0 % vs 5.9 %,P < 0.001) among the three groups.However,there was no impact on treatment related mortality (23.5 %,17.0 %,29.0 %,P =0.190).Multivariate analysis suggested that the composite index affecting the OS,EFS and RR of allogeneic hematopoietic stem cell transplantation (P =0.005,P =0.001,P < 0.001),but not the TRM (P =0.666).To some extent,it was an independent prognosis index on RR.Conclusion The composite index is closely related to the efficacy of allogeneic hematopoietic stem cell transplantation.

ABSTRACT

<p><b>OBJECTIVE</b>To investigate the relationship between serum concentration of fluorouracil and therapeutic efficacy as well as adverse reactions in patients with unresectable locally advanced or measurable metastatic colorectal cancer, and to analyze its role in further improving therapeutic efficacy and reducing adverse reactions of fluorouracil-based chemotherapy.</p><p><b>METHODS</b>Eighty-six patients were randomly assigned into three groups according to the average plasma concentration of fluorouracil after three cycles of chemotherapy with the initial regimen of two weeks FOLFOX-4 (oxaliplatin + leucovorin + fluorouracil) or FOLFIRI (irinotecan + leucovorin + fluorouracil): group 1 (plasma concentration of fluorouracil < 25 ng/ml), group 2 (25 - 35 ng/ml) and group 3 (> 35 ng/ml). The blood samples were taken at 12 h after continuous infusion of fluorouracil in each cycle and the plasma concentration of fluorouracil was detected by high performance liquid chromatography (HPLC) (about 5 am ± 1 h). The relationship between the drug plasma concentration, therapeutic efficacy and adverse reactions in different fluorouracil plasma concentration arms was analyzed retrospectively.</p><p><b>RESULTS</b>The average plasma concentrations of fluorouracil of the three groups were (23.48 ± 1.95) ng/ml, (31.47 ± 2.33) ng/ml and (39.89 ± 3.87) ng/ml, respectively (P < 0.01). As for therapeutic efficacy, the median OS of the groups 2 and 3 were 18.0 and 17.5 months, significantly higher than that in the group 1 (13.0 months, P < 0.01). The PFS were 4.5, 7.5 and 8.0 months, respectively (P < 0.01). In terms of adverse reactions, the incidences of bone marrow suppression, mucositis and diarrhea in the group 3 were significantly higher than that in the first two groups (P = 0.02, P = 0.04 and P = 0.02).</p><p><b>CONCLUSIONS</b>The patients with local advanced and metastatic colorectal cancer, receiving fluorouracil-based chemotherapy, and with an average plasma concentration of fluorouracil between 25 - 35 mg/L have a better prognosis, and lower incidence of adverse reactions such as bone marrow suppression, mucositis and diarrhea.</p>

ABSTRACT

Objective To assess the impact of antithymocyte globulin (ATG) on the incidence of graft-vs-host disease (GVHD) in hematopoietic stem cell transplantation from unrelated donors.Methods A total of 92 patients with hematological malignancies including leukemia,myelodysplastic syndrome (MDS) and lymphoma who underwent hematopoietic stem cell transplantation from unrelated donors from January 1999 to December 2011 were included in this retrospective analysis.Patients were classified into ATG group (n =66)and non-ATG group (n =26) according to the GVHD prophylaxis regimen.The incidence of acute GVHD (aGVHD) and chronic GVHD (cGVHD),risk factors of aGVHD and cGVHD and impact of ATG on the overall survival (OS),treatment related mortality (TRM) and relapse rate were analyzed.Results Grade Ⅱ-Ⅳ aGVHD (26.7 % vs 44.0 %,P=0.12) or grade Ⅲ-Ⅳ aGVHD (13.3 % vs 8.0 %,P =0.74) were not significantly different between ATG and non-ATG group.However,the incidence of cGVHD in the ATG group was significantly lower (34.0 % vs 72.2 %,P =0.005) than non-ATG group.The incidence of extensive cGVHD was also significantly reduced (10.0 % vs 44.4 %,P =0.005) compared to non-ATG group.In multivariate analysis,the use of ATG prophylaxis significantly decreased the cGVHD (RR =0.22,95 %CI 0.081-0.599,P =0.003) while one allele mismatch of human leukocyte antigen (HLA) was associated with increased risk of cGVHD (RR =3.25,95 % CI 1.39-7.61,P =0.007).As to the extensive cGVHD,the use of ATG was the only independent factor (RR =0.05,95 % CI 0.009-0.240,P < 0.001).With a median follow-up of 12 months (1-84 months),ATG prophylaxis had no impact on OS rate (60.4 % vs 43.1%,P =0.41),TRM rate (19.8 % vs 34.3 %,P =0.43) and relapse rate (40.6 % vs 33.6 %,P=0.54).Conclusion In hematopoietic stem cell transplantation from unrelated donors,ATG prophylaxis total dose of 6 mg/kg may significantly decrease the incidence of cGVHD and extensive cGVHD without increase of TRMand relapse rate and impairment of OS.

ABSTRACT

Objective A retrospective analysis of patients with T-cell lymphoma (TCL) received autologous peripheral blood stem cell transplantation (APBSCT) was performed to evaluate the outcome of APBSCT.Methods A total of 22 patients who underwent APBSCT from September 2006 to December 2011 in Ruijin hospital were enrolled in the study,including 6 cases of lymphoblastic lymphoma and 16 of peripheral T-cell lymphoma (8 anaplastic large cell lymphoma, 4 PTCL-u, 1 subcutaneous panniculitis-like T-cell lymphoma, 2 nasal type extranodal NK/T and 1 primary cutaneous T-cell lymphoma). All patients were diagnosed based on the WHO Classification of Tumors of Hematopoietic and Lymphoid Tissues. Conditioning regimens were high-dose chemotherapies alone which include 13 cases with BEAM, 4 with ICE and 5 with CBV. The outcomes of the treatment were evaluated according to the revised International Working Group criteria.Results With a median follow-up of 13.1(1-60) months,the predicted 2-year overall survival (OS) and progression-free survival (PFS) after transplantation were (67.6±11.0) % and (71.1±11.1) %,respectively.A total of 6 patients experienced disease progression and 5 patients eventually died of disease. When all these patients based on the remission status before APBSCT (CR1 vs non-CR1) and chemosensitivity (sensitive vs refractory) were further classified, the PFS rates and OS rates were 100 % and 91.7 % respectively in CR1 or chemosensitive patients which were significantly higher than patients not in CR1 (42.6 % ) or with chemoresistant disease (19.0 % ). Conclusion Remission status and chemosensitivity at the time of transplantation significantly affect the outcome of APBSCT for TCL patients, thus it can be recommend to perform APBSCT for patients either in CR1 or early stage when the disease remain sensitive to chemotherapy.
