ABSTRACT

Objective:This study aimed to evaluate the clinical features and treatment outcomes of the value of response-adapted treatment following radiotherapy and induction chemotherapy follwing subsequent comprehensive therapy in patients with resectable locally advanced hypopharyngeal carcinoma. Methods:This cohort study was conducted from September 2010 to September 2020 in our hospital, 231 patients pathologically confirmed stage Ⅲ and ⅣB resectable locally advanced hypopharyngeal carcinoma included. For the IC-directed ART strategy, IC is used to select good candidates to receive radical RT or CCRT, and others undergo surgery. He response-adapted strategy was determined based on the primary tumor response, which was evaluated at a dose of 50 Gy. If the response reached complete response or partial response(more than 80% tumor regression), patients received radical RT or CCRT; otherwise, they received surgery, if possible, at 4 to 6 weeks after RT. The end points of the study were OS(overall survival), progression free survival(PFS), locoregional recurrence-free survival(LRRFS) and LDFS. Results:In IC-directed group, 75.0%(57/76) patients reached PR after 2 cycles of induction chemotherapy. While in RT-directed group, 70.3%(109/155) patients reached large PR at dose of 50 Gy. The median interquartile range follow-up period of the whole cohort was 63.8 months. The 5-year OS, PFS, LRRFS and SFL of the whole cohort were 47.9%、39.6%、44.3% and 36.2%, respectively. In evaluations based on the different treatment strategies, the 5-year OS and SFL were 51.3% versus 37.0%(HR 0.67; 95%CI 0.43-1.05; P=0.07) and 27.8% versus 39.8%(HR 0.68; 95%CI 0.46-0.99; P=0.04) between IC-directed and RT-directed groups. In additional, surgery complications did not significantly differ between these two groups. Conclusion:In this cohort study, the response-adapted strategy based on an early RT response facilitated better treatment tailoring, and higher laryngeal preservation compared with IC-directed strategies. This approach could provide a feasible laryngeal preservation strategy in patients with resectable locally advanced hypopharyngeal carcinoma.

ABSTRACT

Objective: To evaluate treatment responses, outcomes, and prognostic factors in adults with secondary acute myeloid leukemia (sAML) . Methods: Between January 2008 and February 2021, date of consecutive cases of younger than 65 years of adults with sAML were assessed retrospectively. Clinical characteristics at diagnosis, treatment responses, recurrence, and survival were evaluated. Logistic regression and Cox proportional hazards model were employed to determine significant prognostic indicators for treatment response and survival. Results: 155 patients were recruited, including 38, 46, 57, 14 patients belonging to t-AML, and AML with unexplained cytopenia, post-MDS-AML, and post-MPN-AML, respectively. In the 152 evaluable patients, the rate of MLFS after the initial induction regimen was 47.4%, 57.9%, 54.3%, 40.0%, and 23.1% in the four groups (P=0.076) . The total rate of MLFS after the induction regimen was 63.8%, 73.3%, 69.6%, 58.2%, and 38.5% (P=0.084) , respectively. Multivariate analysis demonstrated that male gender (OR=0.4, 95% CI 0.2-0.9, P=0.038 and OR=0.3, 95% CI 0.1-0.8, P=0.015) , SWOG cytogenetic classification into unfavorable or intermediate (OR=0.1, 95% CI 0.1-0.6, P=0.014 and OR=0.1, 95% CI 0.1-0.3, P=0.004) and receiving low-intensity regimen as induction regimen (OR=0.1, 95% CI 0.1-0.3, P=0.003 and OR=0.1, 95%CI 0.1-0.2, P=0.001) were typical adverse factors impacting the first CR and the final CR; PLT<45 × 10(9)/L (OR=0.4, 95%CI 0.2-0.9, P=0.038) and LDH ≥258 U/L (OR=0.3, 95%CI 0.1-0.7, P=0.005) were independent factors for CR. Among the 94 patients with achieving MLFS, 46 cases had allogeneic hematopoietic stem cell transplantation. With a median follow-up period of 18.6 months, the probabilities of relapse-free survival (RFS) and overall survival (OS) at 3 years were 25.4% and 37.3% in patients with transplantation, and in patients with chemotherapy, the probabilities of RFS and OS at 3-year were 58.2% and 64.3%, respectively. At the time of achieving MLFS, multivariate analysis revealed that age ≥46 years (HR=3.4, 95%CI 1.6-7.2, P=0.002 and HR=2.5, 95%CI 1.1-6.0, P=0.037) , peripheral blasts ≥17.5% at diagnosis (HR=2.5, 95%CI 1.2-4.9, P=0.010 and HR=4.1, 95%CI 1.7-9.7, P=0.002) , monosomal karyotypes (HR=4.9, 95%CI 1.2-19.9, P=0.027 and HR=28.3, 95%CI 4.2-189.5, P=0.001) were typical adverse factors influencing RFS and OS. Furthermore, CR after induction chemotherapy (HR=0.4, 95%CI 0.2-0.8, P=0.015) and transplantation (HR=0.4, 95%CI 0.2-0.9, P=0.028) were substantially linked to longer RFS. Conclusion: Post-MDS-AML and post-MPN-AML had lower response rates and poorer prognoses than t-AML and AML with unexplained cytopenia. In adults with male gender, low platelet count, high LDH, and SWOG cytogenetic classification into unfavorable or intermediate at diagnosis, and receiving low-intensity regimen as the induction regimen predicted a low response rate. Age ≥46 years, a higher proportion of peripheral blasts and monosomal karyotype had a negative effect on the overall outcome. Transplantation and CR after induction chemotherapy were greatly linked to longer RFS.

ABSTRACT

Objective: To evaluate the effect of depth of remission of induction chemotherapy on the overall prognosis of limited stage small cell lung cancer (L-SCLC). Methods: The study was a retrospective, L-SCLC patients who contained complete imaging data and underwent consecutive standardized treatments at the Department of Thoracic Radiation and Medical Oncology, Zhongnan Hospital of Wuhan University between January 2013 and June 2021 were included. To delineate the volume of tumor before and after induction chemotherapy and to calculate the depth of remission caused by the induced chemotherapy. The time receiver operating characteristic (timeROC) method was used to determine the optimal predictors for prognosis, multi-factor analysis using Cox risk proportional model. Results: A total of 104 patients were included in this study. The median PFS and OS of this cohort were 13.7 months and 20.9 months, respectively. It was observed by timeROC analysis that residual tumor volume after induction chemotherapy had the optimal predictive value of PFS at 1 year (AUC=0.86, 95% CI: 0.78~0.94) and OS at 2 years (AUC=0.76, 95% CI: 0.65~0.87). Multivariate analysis showed residual tumor volume after induction chemotherapy was the independent prognostic factor to PFS (HR=1.006, 95% CI: 1.003~1.009, P<0.01) and OS (HR=1.009, 95% CI: 1.005~1.012, P<0.001). For those whose residual tumor volume remitted to less than 10 cm(3) after induction chemotherapy, the favorable long-term outcomes could be achieved, regardless of their initial tumor load. Conclusion: The depth of remission of induction chemotherapy could be a promising prognostic predictor to the L-SCLC and provide the individualized treatment guidance.

ABSTRACT

OBJECTIVES@#To evaluate the effectiveness of induction therapy with exclusive enteral nutrition (EEN) in pediatric Crohn's disease (CD).@*METHODS@#A retrospective analysis was performed on the medical data of 62 children with CD who received EEN in Children's Hospital, Zhejiang University School of Medicine, from March 2013 to August 2021. The medical data included general information and height, weight, Pediatric Crohn's Disease Activity Index (PCDAI), Crohn's Disease Endoscopic Index of Severity, C-reactive protein, erythrocyte sedimentation rate, and serum albumin level before treatment and after 8 weeks of treatment. The changes in the above indicators were compared before and after treatment.@*RESULTS@#Among the 62 children with CD, there were 39 boys (63%) and 23 girls (37%), with a mean age of (11.9±3.0) years at diagnosis. Among the 55 children who completed EEN treatment for at least 8 weeks, 48 (87%) achieved clinical remission at week 8. PCDAI at week 8 was significantly lower than that before treatment (P<0.001). Except for 17 children with involvement of the small intestine alone and 3 children with involvement of the colon who did not receive colonoscopy reexamination, the remaining 35 children with involvement of the colon received colonoscopy reexamination after the 8-week EEN treatment. Of the 35 children, 29 (83%) achieved mucosal healing. As for the 48 children who achieved clinical remission at week 8, there were significant improvements in height-for-age Z-score and body mass index-for-age Z-score at week 8 (P<0.01). As for the 7 children who did not achieve clinical remission at week 8, there were no significant changes in height-for-age Z-score and body mass index-for-age Z-score at week 8 (P>0.05).@*CONCLUSIONS@#The 8-week EEN treatment has a good effect on clinical remission and mucosal healing in children with CD. For the children with CD achieving clinical remission, EEN can improve their height and body mass index.

ABSTRACT

Objective: To evaluate the roles of G Protein-Coupled Receptor 68 (GPR68) and tumor infiltrating lymphocytes (TIL) in TPF-(paclitaxel, cisplatin and 5-fluorouracil) induced chemotherapy for middle-advanced hypopharyngeal squamous cell carcinomas. Methods: A total of 31 patients with middle-advanced hypopharyngeal squamous cell carcinoma before TPF-inducted chemotherapy were enrolled from September 2012 to November 2017 in Beijing Tongren Hospital, Capital Medical University, including 28 males and 3 females, aged 43 to 71 years old. The expression of GPR68 and tumor infiltrating CD4+and CD8+T cells before chemotherapy was detected by immunohistochemical staining, and the relationships between GPR68 expression and clinical features, chemotherapy efficacy and overall survival (OS) were analyzed using t-test. Results: After 3 cycles of chemotherapy, there were 4, 14, 10 and 3 patients respectively with complete response (CR), partial response (PR), stable disease (SD) and progressive disease (PD). The positive rates of GPR68 and CD8 were 25% and 40% respectively in the effective group (CR+PR), while 50% and 15% in the ineffective group (SD+PD), with statistically significant differences between two groups (t=5.17 and 12.86,P<0.001). Linear regression analysis showed that GPR68 was negatively correlated with CD8+T cells (r=-0.64,P<0.001). There was no significant correlation between the CD4 expression and TPF efficacy (P>0.05). The mean OS was 12.5 months in patients with high-expressed GPR68 and 25.0 months in patients with low-expressed GPR68, with a statistically significant difference (P=0.005). And mean OS was 25.0 months in patients with high-expressed CD8 and 14.5 months in low-expressed CD8, with a statistically significant difference (HR=2.58, P=0.019). Cox regression analysis showed that GPR68 and CD8+T cells were significant prognostic factors (OR(95%CI)=3.27(2.46-5.97) and 1.53(0.78-1.82), all P<0.05), while CD4 had no significant effect on prognosis (P>0.05). Conclusion: GPR68 and CD8+T cells are expected to be biomarkers for evaluating the efficacy and prognosis of TPF-induced chemotherapy in patients with middle-advanced hypopharyngeal squamous cell carcinoma.

ABSTRACT

OBJECTIVE@#To explore the effect of age on the time of neutropenia after initial induction therapy for newly diagnosed acute myeloid leukemia (AML) patients.@*METHODS@#Data of 18-65 years old AML patients treated in our hospital from Junuary 2015 to July 2020 were retrospectively analyzed. The clinical characteristics, time of neutropenia after initial induction treatment, early responses, and related influencing factors for the time of neutropenia were analyzed and compared between 18-40 years old group and 41-65 years old group.@*RESULTS@#There were 112 patients enrolled in this study, including 66 (58.9%) males, and their median age was 46 years old. Compared with 18-40 years old group, the incidence of FLT3-ITD gene mutation increased (P=0.039) but core binding factor (CBF) decreased (P=0.003) significantly in 41-65 years old group. The incidence of neutropenia was 97.3%, and the average time was (18.70±1.192) days. The time of neutropenia was (21.43±1.736) days in 41-65 years old group, which was longer than (14.91±1.356) days in 18-40 years old group (P=0.006). The time of neutropenia in CBF positive group was shorter than that in negative group (P=0.012), as well as in patients with remission (CR+CRi) (≤ 2 courses) than those with non-remission (NR) (P=0.024), while in high-risk group was longer than that in low-risk group (P=0.040). Multivariate analysis showed that age, FLT3-ITD gene mutation positive, and non-remission (NR) after two courses of treatment were independent risk factors for the time of neutropenia.@*CONCLUSION@#In non-elderly patients with newly diagnosed AML, age is an influencing factor for the time of neutropenia.

ABSTRACT

Objective: To compare the efficacy of two induction regimens, namely, idarubicin combined with cytarabine (IA) versus the combination of homoharringtonine, daunorubicin, and cytarabine (HAD) , in adult patients with newly diagnosed de novo acute myeloid leukemia (AML) . Methods: From May 2014 to November 2019, 199 patients diagnosed with AML receiving either the IA or HAD regimens were assessed for overall survival (OS) , relapse-free survival (RFS) , as well as the CR rate and the MRD negative rate after induction therapy. The differences in prognosis between the two induction therapy groups was assessed according to factors, including age, white blood cell (WBC) count, NPM1 mutation, FLT3-ITD mutation, 2017 ELN risk stratification, CR(1) transplantation, and the use of high-dose cytarabine during consolidation therapy, etc. Results: Among the 199 patients, there were 104 males and 95 females, with a median age of 37 (15-61) years. Ninety patients received the IA regimen, and 109 received the HAD regimen. Comparing the efficacy of the IA and HAD regimens, the CR rates after the first induction therapy were 71.1% and 63.3%, respectively (P=0.245) , and the MRD negative rates after the first induction therapy were 53.3% and 48.6%, respectively (P=0.509) . One patient in the IA group and two in the HAD group died within 60 days after induction. The two-year OS was 61.5% and 70.6%, respectively (P=0.835) , and the two-year RFS was 51.6% and 57.8%, respectively (P=0.291) . There were no statistically significant differences between the two groups. Multivariate analysis showed that the ELN risk stratification was an independent risk factor in both induction groups; CR(1) HSCT was an independent prognostic factor for OS and RFS in the IA patients and for RFS in the HAD patients but not for OS in the HAD patients. Age, WBC level, NPM1 mutation, and FLT3-ITD mutation had no independent prognostic significance. Conclusion: The IA and HAD regimens were both effective induction regimens for AML patients.

ABSTRACT

La mitad de los pacientes con cáncer de origen colorrectal desarrollan metástasis hepáticas durante el curso de su enfermedad y de esas el 80% son irresecables. La resecabilidad se define no por la extensión de la hepatectomía, sino por la función del hígado remanente, por lo que para pacientes con ciertos factores favorables se pueden realizar técnicas de remodelación hepática para aumentar el volumen del hígado remanente para que este sea suficiente. La hepatectomía en dos tiempos se basa en procedimientos secuenciales que buscan tratar metástasis hepáticas colorrectales consideradas inicialmente irresecables, logrando la resección completa de las mismas dejando un remanente hepático funcionante suficiente, lo cual no sería posible en un solo acto quirúrgico. El objetivo de este trabajo es presentar el caso clínico de un paciente portador de metástasis hepáticas sincrónicas de origen colorrectal irresecables, que luego de una quimioterapia de conversión, con el fin de aumentar el futuro remanente hepático y evitar falla hepática postoperatoria y realizar una resección oncológica, fue sometido a una hepatectomía en dos tiempos, técnica utilizada con baja frecuencia en nuestro medio, destacando una evolución favorable, con marcadores tumorales en valores normales y sin evidencia imagenológica de recaída local ni sistémica.


Half of colorectal cancer patients develop liver metastases during the course of their disease, 80% of which are unresectable. Resectability is defined not by the extent of the hepatectomy, but by the function of the liver remnant. Therefore, for patients with certain factors, liver remodeling techniques can be performed to increase volume of the remaining liver so that it is sufficient. Two-stage hepatectomy is performed on colorectal liver metastases which are initially considered unresectable in one stage resection procedures, in which sequential procedures are performed in order to achieve complete resection and preserve a sufficient functioning liver remnant. The objective of this paper is to present the case of a patient with unresectable synchronous colorectal liver metastases, in which after conversion chemotherapy, in order to increase the future liver remnant, avoid postoperative liver failure and perform an oncological resection underwent a two-stage hepatectomy, a technique used with low frequency in our setting, highlighting a favorable evolution, with tumor markers in normal values and without imaging evidence of local or systemic relapse.


Metade dos pacientes com câncer colorretal desenvolve metástases hepáticas durante o curso da doença e, desses, 80% são irressecáveis. A ressecabilidade é definida não pela extensão da hepatectomia, mas pela função do fígado remanescente; portanto, para pacientes com certos fatores favoráveis, técnicas de remodelação hepática podem ser realizadas para aumentar o volume do fígado remanescente de forma que seja suficiente. A hepatectomia em dois estágios é baseada em procedimentos sequenciais que buscam tratar metástases hepáticas colorretais inicialmente consideradas irressecáveis, obtendo ressecção completa, deixando um remanescente hepático funcional suficiente, o que não seria possível em um único ato cirúrgico. O objetivo deste trabalho é apresentar o caso clínico de um paciente com metástases hepáticas sincrônicas irressecáveis ​​de origem colorretal, que após quimioterapia de conversão, com o objetivo de aumentar o futuro remanescente hepático e evitar insuficiência hepática pós-operatória e realizar uma ressecção oncológica, foi submetido a dois Hepatectomia em estágio, técnica utilizada com baixa frequência em nosso meio, evidenciando evolução favorável, com marcadores tumorais em valores normais e sem evidências de imagem de recidiva local ou sistêmica.

ABSTRACT

OBJECTIVE@#To explore the effect of posaconazole in the primary prevention of invasive fungal disease (IFD) in the induction therapy of childhood acute lymphoblastic leukemia (ALL).@*METHODS@#From August 2018 to November 2020, 144 pediatric patients with ALL treated in Department of Pediatrics, Sun Yat-Sen Memorial Hospital, Sun Yat-Sen University were selected, 88 cases received fluconazole as IFD prophylaxis (fluconazole prophylaxis group), 56 cases received posaconazole as IFD prophylaxis (posaconazole prophylaxis group). The incidence of IFD and treatment-related adverse reactions between the two groups were compared, and the safety of posaconazole was evaluated.@*RESULTS@#The incidence of IFD in the fluconazole prophylaxis group was 20.4% (18/88), and in the posaconazole prophylaxis group was 7.1% (4/56). The incidence of IFD between the two groups was statistically significant different(P=0.030). There was no serious adverse reactions in the two groups. The incidence of mild adverse reactions in the posaconazole prophylaxis group (23.2%) was lower than that in the fluconazole prophylaxis group(39.8%), and the difference was statistically significant (P=0.039). There were 12 cases died in the fluconazole prophylaxis group and 4 in the posaconazole prophylaxis group, while no significant difference in the overall survival rate between the two groups (P=0.281).@*CONCLUSION@#The effect of posaconazole in the primary prophylaxis of IFD is better and incidence of adverse reactions is lower than fluconazole. Posaconazole can be tolerated, and expected to become the first-line primary prophylaxis drug for IFD during the induction remission therapy of childhood ALL.

ABSTRACT

OBJECTIVE@#To explore the relationship between effect of induction chemotherapy and prognosis in acute myeloid leukemia (AML) patients.@*METHODS@#The clinical data of 146 adult AML patients treated in Affiliated Hospital of Chifeng University from March 2015 to March 2018 were enrolled and retrospectively analyzed. Day 14 bone marrow biopsy (D14BM) cellularity and blast proportion, daily peripheral blood blast (PBB) clearance rate, time to PBB clearance and etc. were primarily observed after induction chemotherapy. All the patients were divided into Non-relapse survival group, Relapse survival group, Non-relapse death group and Relapse death group according to survival and recurrence situation during 2-year follow-up. The survival of the patients was analyzed by Kaplan-Meier. Univariate analysis of prognostic factors were performed by ordinal Logistic regression, and ROC curve was used to assess the prediction efficiency of those factors for the 2-year overall survival (OS) and relapse of the patients.@*RESULTS@#A total of 138 patients were included since 8 cases failed to be assessed clinically. Their 2-year OS rate was 65.94%. Age of the patients in Non-relapse survival group was lower than that in Relapse death group. The D14BM cellularities in Non-relapse survival group and Relapse survival group were lower than those in Relapse death group (P10%, while it was higher in patients with daily PBB clearance rate >20% than those with clearance rate≤20% (P0.05).@*CONCLUSION@#Bone marrow biopsy results and PBB clearance rate are related to prognosis in AML patients, which can offer certain predictive value in assessing 2-year OS of patients.

ABSTRACT

OBJECTIVE@#To the clinical characteristics and prognostic value of the patients with complete deletion of TET_JBP domain (ΔJBP) in TET2 acute myeloid leukemia (AML).@*METHODS@#Next Generation Sequencing technology was used to determine the mutations of 34 AML-related genes (including TET2 gene). The I-TASSER tool was used to predict the tertiary structure of the full-length TET2 protein and TET_JBP structure deletion.@*RESULTS@#Among 38 AML patients with TET2 mutations, 22(57.9%) showed truncation mutations, of which 16 (72.7%) produced TET2ΔJBP truncation mutants. Protein structure prediction showed that the deletion of TET_JBP domain lead to the significant changes of tertiary structure in TET2 protein. Compared with the patients in non-ΔJBP group, the age of patients in ΔJBP group were older (63 vs 54 years old, P=0.047), and the occurrence rate of CEBPA double mutation (CEBPA@*CONCLUSION@#AML patients with TET2ΔJBP truncation mutant shows lower CR rate, shorter EFS and OS after induction chemotherapy, which may be related to the poor prognosis, and co-mutation with CEBPA

ABSTRACT

OBJECTIVE@#To analysis the relationship between different BMI (body mass index) and the clinical characteristics, laboratory examination indexes of newly diagnosed adult patients with acute myeloid leukemia (AML), so as to investigate the effects of BMI to the efficacy of first induction chemotherapy.@*METHODS@#The clinical data of 145 newly diagnosed adult AML patients treated in the First Hospital of Lanzhou University from August 2015 to August 2019 were retrospective analyzed. According to the guidelines for prevention and control of overweight and obesity in Chinese adults, the BMI (kg/m@*RESULTS@#Among the 145 newly diagnosed adult AML patients, there were 71 males and 74 females. The median age was 50 years old(range 18 to 82 years old). There were 21 patients in underweight group (14.5%), 79 patients in normal weight group (54.5%), and 45 patients in overweight and obese group (31.0%). The patients with higher BMI level showed the older in age(P=0.018). There were significant differences in sex between the patients in each group(P=0.035). In overweight and obese patients, the number of male was significantly higher than female. There were no statistical differences in AML classification, comorbidities(Diabetes, hypertension, coronary heart disease), hospital days, whether secondary AML and FLT3 gene mutation among the patients in different BMI groups. There were significant differences in TG of the patients in the different groups, the overweight and obese patients were higher (P=0.007). There were no significant differences in WBC and Hb counts, ALB, TC, HDL, LDL, or LDH between the patients in each BMI group at newly diagnosed. The complete remission rate of the patients in the low body mass group or overweight and obese group were lower than that in the normal body weight group (P=0.035). The rate of documented infection during the first induction chemotherapy were significantly higher for the patients in low body mass group than those in normal weight group or overweight and obese group (P=0.038). There was no statistical difference in chemotherapy regimens, the number of chemotherapy until CR, febrile neutropenia, bleeding, and the time of neutropenia, liver and kidney toxicity among each BMI group. Multivariate analysis showed that overweight and obese (P=0.012) , FLT3 mutation (P=0.015) were the risk factors affecting the CR rate of the patients. And the patients with secondary AML, high-risk type, and newly diagnosed WBC ≥50×10@*CONCLUSION@#In newly diagnosed adult patients with AML, low body mass, overweight and obesity, and FLT3 mutations were the factors reducing the early efficacy of AML patients. There were more adverse reactions induced by chemotherapy in the low body mass group. Therefore, inappropriate BMI level can be a risk factor for assessing the prognosis of adults with newly diagnosed AML.

ABSTRACT

OBJECTIVE@#To explore the impact of induction treatment response on the prognosis of pediatric core binding factor-acute myeloid leukemia (CBF-AML).@*METHODS@#The result of induce reaction and survival data of 157 pediatric CBF-AML patients in our hospital from September 2008 to December 2018 were retrospectively analyzed.The survival rate of the patients with different degrees of morphological remission after induction chemotherapy was comparative analyzed.@*RESULTS@#Among the 157 children with CBF-AML, 113 (72.4%) patients achieved morphologic leukemia-free state (MLFS) after the first course of induction chemotherapy, 153 (98.1%) patients achieved MLFS after the second course of induction chemotherapy. The 5-year event-free survival (EFS) rate and 5-year overall survival (OS) rate of patients with non-remission (NR) status after the first course of induction of chemotherapy was significantly lower than the patients achieved MLFS and the patients achieved partial remission (PR). The 5-year EFS rate and 5-year OS rate of the patients with PR status after the second course of induction chemotherapy were lower than the patients achieved MLFS, but the difference was not statistically significant. Multivariable analyze showed that NR after the first course of induction chemotherapy and myeloid sarcoma were the independent risk factors affecting EFS of the patients. There were six patients with NR status after the first course of induction chemotherapy, in which all of them harbored t(8;21), three of them with sex chromosome deletion, two of them with myeloid sarcoma.@*CONCLUSION@#NR status after the first course of induction chemotherapy was the independent risk factor affecting EFS and OS of CBF-AML patients, it can be taken as an indicator for higher risk stratification. PR status after the first course of induction chemotherapy may not be used as a diagnostic criterion for primary drug resistance.

ABSTRACT

OBJECTIVE@#To investigate the influence of influence of combination with 1q21 amplification or-no in patients with newly diagnosed MM on the clinical effecacy of bortezomib-based induction chemotherapy and long-term prognosis of patients.@*METHODS@#148 patients with newly diagnosed MM treated from January 2010 to May 2018 were selected and divided into 2 groups: group A (70 patients) without 1q21 amplification and group B (78 patients) with 1q21 amplification; and the survival benefit and influence on clinical efficacy of bortezomib were compared between 2 groups, and the factors influencing clinical prognosis in the patients with newly diagnosed MM were analyzed.@*RESULTS@#The median PFS and OS of patients in B group were significantly shorter than those in group A (P<0.05). There was no significant difference in the median OS and PFS between patients with 1q21 amplification copies number =3 and >3 (P>0.05). Multivariate Cox model analysis indicated that the adverse factors for OS were ISS staging, Hb levels, β2 microglobulin levels and 1q21 amplification respectively, and the adverse factors for PFS were Hb levels and 1q21 amplification respectively in patients with newly diagnosed MM (P<0.05). The very good partial remission rate of newly diagnosed MM patients with 1q21 amplification and bortezomib-based induction chemotherapy were significantly higher than that in the patients without bortezomib-based induction chemotherapy (P<0.05). The median PFS time of newly diagnosed MM patients with 1q21 amplification and auto-HSCT after bortezomib-based induction chemotherapy was significantly longer than that of patients without auto-HSCT (P<0.05).@*CONCLUSION@#1q21 amplification should be the independent risk factor for poor prognosis of patients with newly treated MM. The application of bortezomib-containing induction chemotherapy in patients with 1q21 amplification can efficiently improve the remission rate, while auto-HSCT consolidation therapy may prolong patients' PFS.

ABSTRACT

Objective: To compare the time of the recovery of neutrophils or leukocytes by pegylated recombinant human granulocyte stimulating factor (PEG-rhG-CSF) or common recombinant human granulocyte stimulating factor (rhG-CSF) in the myelosuppressive phase after induction chemotherapy in newly diagnosed acute myeloid leukemia (AML) patients. At the same time, the incidences of infection and hospitalization were compared. Methods: A prospective randomized controlled trial was conducted in patients with newly diagnosed AML who met the enrollment criteria from August 2014 to December 2017. The patients were randomly divided into two groups according to a 1:1 ratio: PEG-rhG-CSF group and rhG-CSF group. The time of neutrophil or leukocyte recovery, infection rate and hospitalization interval were compared between the two groups. Results: 60 patients with newly diagnosed AML were enrolled: 30 patients in the PEG-rhG-CSF group and 30 patients in the rhG-CSF group. There were no significant differences in age, chemotherapy regimen, pre-chemotherapy ANC, WBC, and induction efficacy between the two groups (P>0.05) . The median time (range) of ANC or WBC recovery in patients with PEG-rhG-CSF and rhG-CSF were 19 (14-35) d and 19 (15-26) d, respectively, with no statistical difference (P=0.566) . The incidences of infection in the PEG-rhG-CSF group and the rhG-CSF group were 90.0%and 93.3%, respectively, and there was no statistical difference (P=1.000) . The median days of hospitalization (range) was 20.5 (17-49) days and 21 (19-43) days, respectively, with no statistical difference (P=0.530) . Conclusions: In AML patients after induction therapy, there was no significant difference between the application of PEG-rhG-CSF and daily rhG-CSF in ANC or WBC recovery time, infection incidence and hospitalization time.
