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.

BACKGROUND/AIMS: This study evaluated the diagnostic efficacy of fluorine-18 fluorodeoxyglucose PET/CT (F-18 FDG PET/CT) for patients with gastric mucosa-associated lymphoid tissue (MALT) lymphoma and examined the association between FDG avidity and the clinical factors affecting lesions. METHODS: Among the patients diagnosed with gastric MALT lymphoma, 16 who underwent a PET/CT for gastric MALT lymphoma were semi-quantitatively and qualitatively tested for FDG avidity of lesions in the stomach. Retrospectively collected data was analyzed to investigate the clinicoradiological factors and endoscopic findings between the patients with positive F-18 FDG PET/CT scans and those with negative scans. RESULTS: Eight of the 16 patients showed FDG avidity. When comparing the size of lesions in the stomach, the patients with FDG avidity had significantly larger lesions than those without (28.8 mm vs. 15.0 mm, p=0.03). The FDG-avid group has a significantly higher rate of positive CT scans than the non-avid group (75% vs. 13%, p=0.03). According to the endoscopic finding of the lesions, FDG avidity was pronounced with 75% of the protruding tumors, and 100% of the erosive-ulcerative types, which are a type of depressed tumors. CONCLUSIONS: When gastric MALT lymphoma is large, when lesions are found using abdominal CT scans, and the macroscopic appearance of a lesion is that of a protruding tumor or erosive-ulcerative type of depressed tumor, there is a high probability that such patients may have a positive F-18 FDG PET/CT scan.

OBJECTIVETo determine the CARD11 expression and its prognostic value in diffuse large B cell lymphoma (DLBCL).

METHODSThis retrospective study included previously untreated patients diagnosed with DLBCL from January 2007 to December 2012. Formalin-fixed, paraffin-embedded blocks of these patients were collected. Tissue microarray was built and expression of CARD11 was examined immunohistochemically. Subtype of DLBCL was determined by Hans algorithm (CD10, BCL6, MUM1). The pattern of CARD11 was further studied and their correlation with outcome was analyzed.

RESULTS79 patients with DLBCL were enrolled and two reactive lymph nodes were used as control. The positive rate of high CARD11 expression in DLBCL was 65.33%, which showed no significant associations with patients' characteristics. Positive CARD11 expression was associated with an inferior event free survival (EFS)(2- year EFS: 52.03%vs 86.12%,P=0.036). Even in patients with a high international prognostic index (IPI, 3-5 points), this difference still remained significant (Median EFS not reached vs 557 days,P=0.033).

CONCLUSIONDLBCL patients with high CARD11 expression had a shorter EFS compared with low level of CARD11. This difference remained significant when patients were in high IPI (3-5 points), which might indicate the value of CARD11 in stratification of high-risk DLBCL patients.

OBJECTIVETo explore the feasibility and value of detecting CyclinD1 and BCL-2 in patients with B-cell lymphoma by using flow cytometry.

METHODSFifty-three patients with lymphoma were selected, and 50 healthy persons in the same period were selected as control. The expression levels of CyclinD1 and BCL-2 in patients with various subtypes of lymphoma were detected by using flow cytometry (FCM).

RESULTSWhen the dilution time was 1 min and the dilution proportion was 1:20, the cell morphology was the best complete, at the 4 min the cell morphology was best status. The mean fluorescence intensity of CyclinD1 and BCL-2 between persons of control group and patients with B-cell lymphoma showed significant difference, the CyclinD1 level (1.824 ± 0.315) and BCL-2 levels (4.257 ± 0.528) of patients with B-cell lymphoma were obviously higher than the CyclinD1 level (0.634 ± 0.153) and BCL-2 level (1.926 ± 0.328) of persons in control group, the CyclinD1 and BCL-2 expression levels of patients with HL were significantly lower than CyclinD1 and BCL-2 levels of patients with NHL (P < 0.01). After treatment, the expression levels of CyclinD1 and BCL-2 in patients with B lymphoma were significantly lower than these befor treatment.

CONCLUSIONUsing the method of flow cytometry for detecting CyclinD1 and BCL-2 expression levels in lymphoma cells of patients is feasible, and it can be applied clinically to evaluate the treatment efficacy.

OBJECTIVETo study the clinical significance of P53, C-MYC and BCL-6 abnormality in the patients with diffuse large B cell lymphoma (DLBCL).

METHODSFrom July 2011 to January 2013, 80 patients with DLBCL were admitted in our hospital and were chosen as study objects, their clinical data were collected. The abnormality of P53, C-MYC and BCL-6 was examined by using I-FISH for all the patients. The correlation of abnormality of P53, C-MYC and BCL-6 with clinical staging, curative efficacy and prognosis of the patients were analyzed.

RESULTSOut of 80 patients 27 patients (33.75%) had P53 deletion, 24 patients (30.00%) had C-MYC rearrangement/amplification, and 46 patients (57.50%) had BCL-6 rearrangement. The P53 deletion, C-MYC rearrangement/amplification and BCL-6 rearrangement significantly correlated with staging, curative effect and prognosis of the patients (P < 0.05).

CONCLUSIONThe curative efficacy and prognosis of the DLBCL patients with abnormality of P53, C-MYC and BCL-6 have been confirmed to be unsatisfactory.

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.
