OBJECTIVE: To explore a predictive model that can better predict the prognosis of patients with diffuse large B-cell lymphoma (DLBCL), and validate its clinical value. METHODS: Clinical data of 134 newly treated DLBCL patients were collected from Xinhua Hospital Affiliated to Shanghai Jiao Tong University School of Medicine from January 2015 to January 2020. Several risk factors of the patients were screened and analyzed, a novel prognostic model were then established based on this, and its clinical application potential was validated. RESULTS: In the novel model, predicting progression-free survival (PFS) based on the age at initial treatment, albumin level, Hans classification, Ann Arbor stage, and BCL2 expression showed better predictive performance than International Prognostic Index (IPI) score (AUC: 0.788 vs 0.620，P <0.001). Predicting overall survival (OS) based on the age at initial treatment, albumin level, lactate dehydrogenase (LDH) level, and expressions of BCL2 and MUM1 proteins also showed better predictive performance for mortality risk than IPI score (AUC: 0.817 vs 0.624，P <0.001). CONCLUSION This novel prognostic model can better predict the survival prognosis of DLBCL patients compared to the IPI scoring system.

OBJECTIVE: To analyze the correlation between the expression levels of Tim-3, C-myc and the proportion of T lymphocyte subsets and prognosis in patients with acute lymphoblastic leukemia (ALL). METHODS: The research group selected 60 ALL patients admitted to our hospital from December 2019 to December 2021, while the control group selected 55 healthy volunteers who underwent physical examination in our hospital. The expression levels of Tim-3, C-myc mRNA and the proportion of T lymphocyte subsets in the two groups were detected. The mortality rate of ALL patients was calculated, and the correlation between the expression levels of Tim-3, C-myc, and the proportion of T lymphocyte subsets and pathological features and prognosis was analyzed. RESULTS: Compared with the control group, the levels of Tim-3, C-myc and CD8⁺ in the research group were increased, while the levels of CD3⁺ , CD4⁺ and CD4⁺ /CD8⁺ were decreased (all P < 0.001). The levels of Tim-3, C-myc mRNA, CD3⁺ , CD4⁺ , CD8⁺ , CD4⁺ /CD8⁺ were correlated with risk classification and extramedullary infiltration (all P < 0.05). The survival rate of patients with low expression of Tim-3, C-myc, and CD8⁺ was higher than that of patients with high expression, while the survival rate of patients with high expression of CD3⁺ , CD4⁺ , and CD4⁺ /CD8⁺ was higher than that of patients with low expression (all P < 0.05). Univariate analysis showed that the deceased patients had higher proportions of extramedullary infiltration and high-risk classification, as well as higher levels of Tim-3, C-myc, and CD8⁺ , while lower levels of CD3⁺ , CD4⁺ , and CD4⁺ /CD8⁺ compared with surviving patients (all P < 0.01). Multivariate logistic regression analysis showed that extramedullary invasion, risk classification, Tim-3, C-myc, CD3⁺ , CD4⁺ , CD8⁺ , CD4⁺ /CD8⁺ were the main factors affecting the prognosis of ALL patients (all P < 0.05). ROC curve analysis showed that the combination of Tim-3, C-myc, and T lymphocyte subsets had higher sensitivity and accuracy in predicting prognosis of ALL patients compared with the single diagnosis of Tim-3, C-myc, CD3⁺ , CD4⁺ , CD8⁺ , and CD4⁺ /CD8⁺ (P < 0.05). CONCLUSION ALL patients show higher levels of Tim-3, C-myc mRNA and CD8⁺ but lower levels of CD3⁺ , CD4⁺ and CD4⁺/CD8⁺. Moreover, the expression levels of Tim-3, C-myc, CD3⁺ , CD4⁺ , CD8⁺ and CD4⁺/CD8⁺ are correlated with extramedullary invasion, high-risk classification and prognosis.

OBJECTIVE: p53 gene, as "the guardian of the genome", is the most widely studied tumor suppressor gene. Previous studies have shown that about 50 percent of tumors have P53 dysfunction. This article aims to retrospectively analyze the correlation between p53 rs1625895 polymorphism and the prognosis of patients with diffuse large B-cell lymphoma (DLBCL). METHODS: PCR combined with Sanger sequencing were used to detect rs1625895 genotype in 384 DLBCL patients. The relationship between rs1625895 polymorphisms and the clinical characteristics, first-line therapeutic effects and the prognosis of the patients were analyzed. RESULTS: Among all the patients, 2 (0.5%) patients with AA genotype, 34 (8.9%) patients with AG genotype and 348 (90.6%) patients with GG genotype were identified. The patients with different rs1625895 genotypes did not have any difference in terms of age, gender, B symptoms (developing any of the following symptoms: unexplained recurrent fever (often above 38 °C), night sweats, and unexplained weight loss of 10% within 6 months ), erythrocyte sedimentation rate (ESR), international prognostic index (IPI) and molecular subtype (P>0.05). The overall response rate (ORR) was 82.9% and 82.8% in AA/AG and GG, respectively. There was no significant difference between the first-line therapeutic effects of the two groups (P>0.05). And there was also no difference between A allele carriers and homozygous G allele carriers for the 5-year progressionfree survival rate (PFS) (71.8% vs. 62.3%, χ²=1.351, P=0.245) and 5-year overall survival rate (OS) (72.2% vs. 64.1%, χ²=1.267, P=0.260). But in the subgroup with Germinal Center B-cell (GCB) type, the patients carrying A allele for rs1625895 had an obviously longer PFS (91.7% vs. 72.7%, χ²=4.493, P=0.034) and OS (91.7% vs. 76.7%, χ²=4.246, P=0.039) compared with the patients homozygous for the G allele. As for the patients with non-GCB subtype, there was no significant difference in PFS and OS between different rs1625895 genotypes (P>0.05). According to whether the first-line regimen contained rituximab or not, the patients were divided into two groups treated with cyclophosphoramide, doxorubicin, vincristine and prednisone (CHOP) or with rituximab and CHOP (R-CHOP). But in both subgroups, there was no significant difference in the 5-year PFS and OS between the AA/AG and GG patients, too (P>0.05). CONCLUSION For DLBCL patients receiving CHOP regimen chemotherapy in the first line, p53 rs1625895 cannot predict the clinical efficacy and prognosis of the patients, but in the patients with GCB subtype, this polymorphism may be a prognostic indicator.

BACKGROUND: As the morbidity and mortality in lung cancer keep raising, we are here to discuss the effect of clinical features especially the initial symptomon on diagnosis and follow-up treatment of newly diagnosed lung cancer patients. METHODS: The clinical features of the 500 patients with lung cancer in our hospital from March, 2017 to May, 2017 were analyzed retrospectively, including the initial symptom, stage, biomarkers, pathology, etc. RESULTS: There were 266 famle (53.3%), 372 adenocarcinoma (74.4%), 285 smokers (58%), status score of most patients (98.2%) was 0-1. 58.2% (n=291) of all the patients got biomarkers test, of which epidermal growth factor receptor (EGFR) mutations was 61.2%(178/291), anaplasticlymphoma kinase (ALK) fusion gene positive was 4.1% (12/291). Smoking status, initial symptom, pathological typing, TNM staging and EGFR mutation were the main factors affecting follow-up treatment. CONCLUSIONS Patients with typical symptoms have shorter diagnosis time. Smoking status, lung cancer-related symptoms, pathology, TNM staging and EGFR mutation status are the main factors that affect the follow-up treatment.

OBJECTIVETo evaluate the expression and clinical significance of tumor necrosis factor receptor (TNFR) superfamily protein CD30 in diffuse large B cell lymhoma (DLBCL).

METHODSThe CD30 expression, clinical characteristics and prognosis of 63 patients with DLBCL, NOS out of 149 patients with DLBCL admitted in our hospital between January 2008 and December 2012 were analyzed retrospectively.

RESULTSno significant relationship existed between CD30 expression and clinical features, such as age, sex, B symptoms, staging, ECOG PS, LDH level, extranodal site involvement, IPI, GCB or non GCB type, bone marrow involvement. By univariate analysis, the clinical factors associated with general OS and EFS, included CD30, ECOG PS, B symptoms, extranodal site involvement, LDH level, IPI, bone marrow involvement and rituximab. Univariate analysis in GCB DLBCL indicated that CD30 had no significant effect on OS and EFS. However, univariate analysis in non-GCB DLBCL indicated CD30 was associated with longer OS (P=0.037) and showed a tendency of better EFS (P=0.067). In multivariate analysis, IPI and CD30 were independent prognostic factors for OS (IPI: P=0.000, 95%CI 0.042-0.374, CD30: P=0.044, 95%CI 1.055-60.613), and IPI also was independent prognostic factors for EFS (P=0.000, 95%CI 0.040-0.360). CD30+ and DLBCL have a tendency of better EFS (P=0.050, 95%CI 0.996-56.501).

CONCLUSIONCD30 expression level correlates with the prognosis of DLBCL and has a certain clinical value, which may be a new prognostic index of DLBCL.

OBJECTIVETo study the signal patterns of dual color dual fusion fluorescence in situ hybridization (DCDF-FISH) for detection of genetic abnormality in adult acute lymphoblastic leukemia (ALL) patients and their diagnostic value and clinical application.

METHODSThe clinical data of 68 ALL patients confirmed in our hospital were analyzed retrospectively; The bone marrow samples were detected by DCDF-FISH, flow cytometry, conventional cytogenetics (CCG), reverse transcriptase polymerase chain reaction (RT-PCR), and the correlation of these results was compared. And the reaction of patients to treatment was dynamically observed by DCDF-FISH.

RESULTSSixteen signal patterns were found in DCDF-FISH, including 14 kinds of atypical signal patterns (signal patterns of 1R2G, 2R3G, 2R4G and 3R3G as abnormal signal patterns without BCR/ABL fusion gene. Signal patterns of 1R1G1F, 1R1G3F, 1R1G4F, 1R2G1F, 1R2G2F, 1R2G3F, 1RnG2F (n ≥ 3), 2R2G1F, 1G4F, 1R4F corresponded to t (9;22) karyotype). Ph(+) ALL patients accounted for 17. All cases with Ph chromosome or BCR/ABL positive were B-ALL or My(+)-B-ALL. The Ph chromosome was detected in 12 cases (positive rate was 18%) by CCG. The positive rate was 25% (17/68) by DCDF-FISH and RT-PCR. The DCDF-FISH fluorescence pattern change before and after chemotherapy of the patients showed that the quantity and form of the signal pattern was changed after chemotherapy, and the common characteristics was the Ph chromosome in patients.

CONCLUSIONThe DCDF-FISH is a sensitive and reliable method for the detection of BCR/ABL rearrangement. Analyzing the dynamical change of DCDF-FISH signal patterns has been comfirmed to have a important guiding significance in the diagnosis, and anlysis of response to therapy, drug resistance and the prognosis of ALL patients.

BACKGROUND: Intrachromosomal amplification of chromosome 21 (iAMP21) is known to be associated with poor prognosis in B-cell ALL (B-ALL). To determine the frequency and clinical characteristics of iAMP21 in Korean B-ALL patients, we performed FISH and multiplex ligation-dependent probe amplification (MLPA) analyses. METHODS: A total of 102 childhood B-ALL patients were screened with ETV6-RUNX1 FISH probes (Abbott Molecular, USA). The presence of an iAMP21 was confirmed by using MLPA P327 iAMP21-ERG probemix (MRC Holland, The Netherlands). RESULTS: iAMP21 was detected in one of the screened B-ALL patients (1/102 patients, 1.0%) who presented the ALL immunophenotype and complex karyotype at initial diagnosis. The patient relapsed twice after bone marrow transplantation. MLPA showed 12.5-Mb and 4.28-Mb regions of amplification and deletion, respectively. CONCLUSIONS: The frequency of iAMP21 is considerable in Korean pediatric patients. Our report suggests that iAMP21 in childhood B-ALL has very unfavorable impact on patient's prognosis. Additional methods such as MLPA analysis is essential to rule out patients with equivocal interphase FISH results.

OBJECTIVETo investigate the clinicpathologic features and diagnosis of plasmablastic lymphoma (PBL).

METHODSEleven cases of PBL were collected and followed up, with review of the literature. HIV and EBV status and their relationships with the tumor were specially compared as well.

RESULTSIn the current cohort, 10 patients were serologically HIV negative; the male to female ratio was 8 to 3, and the median age was 57 years. Ten cases showed extranodal involvement and one case was nodal based. At presentation, five patients had mid-facial involvement, including sinonasal area (3 cases) and oral cavity (2 cases). Histologically, six were PBL of oral mucosa type, and five were PBL with plasmacytic differentiation. In all cases, the neoplastic cells expressed CD138 and MUM-1, and were negative for CD20 and CD3ε; the median Ki-67 index was 80%. Five cases were EBER1/2 in situ hybridization positive. IgH or/and Igκ gene rearrangement was detected in all five cases examined.

CONCLUSIONSMost patients were no congenital or acquired immunodeficiency in the retrospective study. Of the died patients, EBER1/2 in situ hybridization were negative and their disease staging were Ⅳ, The neoplastic cells were immunoblastic or plasmablastic, sometimes the plasmacytoid cell can be seen and the neoplastic cell had mature plasma cell phenotype, the pathologic diagnosis of the lymphoma is still controversial now. Differentiate with plasma cell neoplasm is difficult, it is necessary to accumulate more cases for advanced study and observation in the future.
