ABSTRACT

Objective:To investigate the prognosis and its influencing factors of elderly patients with diffuse large B-cell lymphoma (DLBCL), and to provide references for clinical treatment.Methods:The clinical data of 152 patients with DLBCL aged over 60 years old from January 2013 to June 2017 in Shanxi Provincial Cancer Hospital were retrospectively analyzed. Kaplan-Meier method was used for survival analysis, and the log-rank test was used for univariate analysis of factors affecting the prognosis of patients, and the Cox proportional hazard regression model was used for multivariate analysis.Results:The median overall survival (OS) time of 152 elderly patients with DLBCL was 36 months (32-40 months), and the 1, 2, and 3-year OS rates were 80.26%, 61.84%, and 57.24%, respectively. Univariate analysis showed that the differences in the 3-year OS rates of elderly DLBCL patients with different gender, clinical staging, lactate dehydrogenase (LDH), Ki-67, β 2-microglobulin (β 2-MG) levels, smoke history, use of rituximab and CHOP regimens were statistically significant (all P < 0.1). The results of multivariate Cox regression analysis showed that male, late clinical staging, elevated LDH, and elevated β 2-MG were risk factors for the OS of elderly DLBCL patients (all P < 0.05). The use of rituximab and CHOP regimens were the protective factors for the OS of elderly patients with DLBCL (all P < 0.05). Conclusions:The elderly male DLBCL patients with late clinical staging, elevated LDH and elevated β 2-MG have a poor prognosis, and the elderly DLBCL patients treated with CHOP regimen and rituximab have a better prognosis.

ABSTRACT

Objective:To explore the factors influencing complete remission in patients with diffuse large B-cell lymphoma (DLBCL), and to explore the effect of the interaction of Karnofsky performance status scale (KPS) scores and the level of lactate dehydrogenases (LDH) on whether patients with DLBCL are completely relieved.Methods:The clinical data of 373 DLBCL patients admitted to Shanxi Province Cancer Hospital from January 2014 to December 2020 were retrospectively analyzed. SPSS 25.0 logistic regression model and Cox proportional risk regression models were used to explore the factors affecting complete remission in patients with DLBCL and to explore whether there was a multiplicative interaction between the factors. For factors with multiplicative interactions, the Matrix package, epiR package, and survival package in R 4.2.0 software were used to analyze whether there was an additive interaction. The relative excess risk of interaction (RERI), attributable proportion due to interaction (AP), and the synergy index (S) were used to evaluate the presence of additive interactions.Results:Elevated β 2 macroglobulin (β 2-MG), KPS scores below 80, and elevated LDH were risk factors for incomplete remission in patients with DLBCL (all P < 0.05). The risk of incomplete remission in patients with elevated β 2-MG, KPS scores below 80 and LDH was 1.971 times ( OR = 1.971, 95% CI 1.161-3.346), 2.056 times ( OR = 2.056, 95% CI 1.057-4.000) and 3.351 times ( OR = 3.351, 95% CI 1.783-6.300) higher than those in patients with normal β 2-MG, KPS scores above 80 and non-elevated LDH, respectively. There was a negative multiplicative interaction between the two risk factors of KPS scores below 80 and elevated LDH ( OR = 0.317, 95% CI 0.126-0.785). The estimated value of RERI, AP and S was -2.07 (95% CI -4.79-0.64),0.50 (95% CI -1.68-0.32),0.50 (95% CI 0.22-1.13), respectively; and there was no additive interaction among them. Conclusions:Elevated β 2-MG, KPS scores below 80, and elevated LDH are risk factors influencing incomplete remission for patients with DLBCL. The combined effect in patients with the combination of elevated LDH and KPS scores below 80 is lower than the single effect of the multiple of the both. There is a negative multiplicative interaction and no additive interaction in DLBCL patients with KPS scores below 80 and elevated LDH level.

ABSTRACT

Objective:To investigate the clinical characteristics of primary thyroid lymphoma (PTL) and the differences in clinical manifestations and survival between the two main pathological subtypes of PTL.Methods:The clinical data of 52 patients with PTL diagnosed in Shanxi Province Cancer Hospital from January 2011 to January 2022 were retrospectively analyzed. The clinical characteristics and survival between the two main pathological subtypes [diffuse large B-cell lymphoma (DLBCL) and mucosa-associated lymphoid tissue lymphoma (MALT)] were compared.Results:Among 52 PTL patients, there were 12 males and 40 females, with a median age of 65 years old (34-83 years old). All patients presented with anterior cervical mass at the time of visit. MALT was diagnosed in 12 cases (23.1%). DLBCL was diagnosed in 37 cases (71.2%), of which 5 cases were double/triple expression lymphoma. B-cell lymphoma (unclassified) was diagnosed in 2 cases (3.8%). Follicular lymphoma (FL) was diagnosed in 1 case (1.9%). There was statistical difference in the proportion of patients with cervical lymph node enlargement between MALT and DLBCL patients [66.7% (8/12) vs. 94.6% (35/37), χ2 = 4.23, P < 0.05]. The 3-year OS rates of MALT and DLBCL patients were 90.9% and 73.9%, and the difference in OS between the two groups of patients was statistically significant ( χ2 = 5.11, P = 0.024). Conclusions:Pathological subtypes of PTL are related to the prognosis of patients.

ABSTRACT

Objective:To investigate the effects of solute carrier family 39 (SLC39) A14 on proliferation, migration and invasion of diffuse large B-cell lymphoma (DLBCL) OCI-LY3 cells.Methods:The human DLBCL cell line OCI-LY3 was divided into Vector group (transfected with empty control plasmid) and SLC39A14 group (transfected with SLC39A14 plasmid). The proliferation of OCI-LY3 cells in the two groups was detected by CCK-8 method, the migration and invasion of cells were detected by Transwell method, and the expression level of SLC39A14 protein and the expressions of PI3K-AKT-mTOR signaling pathway-related proteins in OCI-LY3 cells were detected by Western blotting.Results:Compared with the Vector group, the cell proliferation ability in the SLC39A14 group was increased from day 3 to day 5 (all P < 0.05).The results of Transwell cell migration assay showed that the number of migrating cells after 36 h in the Vector group was (64±4) cells, and that in the SLC39A14 group was (236±25) cells. The cell migration ability in the SLC39A14 group was increased, and the difference was statistically significant ( t = 15.02, P < 0.05). The results of Transwell cell invasion assay showed that the number of invasive cells in the Vector group was (32±2) cells, and that in the SLC39A14 group was (127±17) cells. The cell invasion ability in the SLC39A14 group was increased, and the difference was statistically significant ( t = 8.33, P < 0.05).The results of Western blotting showed that the expression levels of pmTOR, pAKT and pPI3K proteins in the SLC39A14 group were all increased. Conclusions:SLC39A14 may be involved in the occurrence and development of DLBCL through PI3K-AKT-mTOR signaling pathway.

ABSTRACT

Objective:To investigate the variation trend of peripheral blood CD34 + cells during the hematopoietic stem cell mobilization and its influence on the collection timing and results. Methods:The clinical data of 62 patients with hematologic diseases undergoing autologous peripheral blood hematopoietic stem cell mobilization from April 2012 to March 2017 in Shanxi Provincial Cancer Hospital were analyzed. Mobilization regimen used chemotherapy combined with granulocyte colony-stimulating factor (G-CSF) to monitor the number of white blood cells (WBC), mononuclear cells (MNC), CD34 + cells in peripheral blood and apheresis concentrates, and the correlation with CD34 + cells was analyzed. Furthermore, the receiver operating characteristic (ROC) curve was used to establish the threshold to start apheresis. Results:MNC (5.66±1.11)×10 8/kg and CD34 + cell count (2.15±1.20)×10 6/kg were obtained in 62 patients who received 136 times collection in total. The peak of peripheral blood CD34 + cells count appeared at day 4-5 after the treatment of G-CSF, and then it went down. CD34 + cell count in the product was correlated with the peripheral blood CD34 + cell count collected on the day ( r = 0.879, P < 0.01), and it was also correlated with the peripheral blood WBC and MNC collected on the day as well as MNC count in the product (all P < 0.05). Furthermore, the ROC curve analysis demonstrated that peripheral blood CD34 + cells count > 23/μl was the optimal threshold for stem cell collection on the day, 85.2% of patients reaching up to the threshold could be successfully collected at one time. Conclusions:The variation trend of peripheral blood CD34 + cell count can guide the best time of stem cell collection in clinic. Peripheral blood CD34 + cell count is the reliable index to predict CD34 + cells count in the products. Peripheral blood CD34 + cells count > 23/μl could be used as the collection threshold.

ABSTRACT

Lymphoma is a group of complex malignant tumors of the lymphohematopoietic system, and its incidence rate is increasing year by year, but the etiology is still unknown. It is generally believed that it is the result of synergistic effect of genetic factors, physical and chemical factors (including radiation, air pollution, lifestyles, eating habits, etc.), biological factors (bacteria and virus infection) and so on. This article reviews the research progress on the relationship between some lifestyles and eating habits and the risk of lymphoma, in order to improve the attention and change of unhealthy lifestyles and eating habits.

ABSTRACT

Objective@#To explore the factors influencing the mobilization and collection of autologous peripheral blood stem cells.@*Methods@#The clinical data of 62 patients who received autologous peripheral blood hematopoietic stem cell mobilization in Shanxi Provincial Cancer Hospital from April 2012 to March 2017 were collected. The effects of age, gender, disease type, chemotherapy cycle, disease status, different schemes and the number of CD34+ cells in peripheral blood of patients 1 d before collection on the number of CD34+ cells and the success rate of CD34+ cells collection were analyzed. Measurement data were compared by one-way ANOVA and t test; count data were compared by χ 2 test; multivariate analysis was performed by multiple linear regression analysis.@*Results@#There were statistically significant differences in the number of CD34+ cells between patients with chemotherapy >6 cycles and ≤6 cycles [(2.6±1.3)×106/kg vs. (5.8±2.2)×106/kg; t = 5.221, P < 0.01], and the difference in the success rate of CD34+ cell collection between the two groups was statistically significant [68.8% (11/16) vs. 97.8% (45/46); χ2 = 8.396, P = 0.004]. The difference in the CD34+ cells yield was not statistical significance between male and female patients [(5.4±2.2)×106/kg vs. (4.5±2.8)×106/kg; t = 1.302, P = 0.198)], but the collection success rate in males was higher than that in females [97.6% (40/41) vs. 76.2% (16/21)], and the difference was statistically significant (χ 2 = 5.017, P = 0.025). The success rate of CD34+ cell collection in patients with ≥10/μl CD34+ cell in the peripheral blood was significantly higher than that in patients with < 10/μl CD34+ cells 1 d before the collection[97.9% (47/48) vs. 64.3% (9/14)], and the difference was statistically significant (χ 2 = 10.668, P = 0.001). The differences in CD34+ cells yield and collection success rate between patients with different age, disease type, disease status and mobilization regimen were not statistically significant (all P > 0.05). Multi-factor analysis showed that > 6 cycles chemotherapy before mobilization was the adverse factor affecting stem cell collection (b = -3.435, P < 0.01).@*Conclusions@#The effective mobilization and collection of autologous peripheral blood stem cells are related to the number of chemotherapy cycles before mobilization. The stem cell mobilization and collection should be conducted as soon as possible when the chemotherapy is ≤ 6 cycles and the patient reaches partial remission or above. In addition, peripheral blood CD34+ cell count should be monitored during mobilization. When the peripheral blood CD34+ cell count is > 10/μl, the collection could be started on the next day to obtain a better collection effect, so as to improve the success rate of collection.

ABSTRACT

Objective To investigate the significance of the expression of serum LDH and β2-MG in predicting survival of NHL patients and there correlations with clinical parameters. Methods The serum levels of LDH and β2-MG of 429 patients with NHL were measured by rate method and immunoturbidimetry.Besides,the clinical reference of the patients such as gender,age,B symptoms,clinical stages,extranodal sites and Karnofsky evaluation were summarized and grouped.All patients' survival status were achieved via phone and letter. All statistical analyses were performed using the SPSS program for Windows (version 16.0).Results The levels of LDH and β2-MG in age,B symptom,the advanced stage,extranodal sites≥2,Karnofsky evaluation were obviously higher than their counterpart and the difference was significant (P<0.001). The median of LDH and β2-MG lever in age group was 229 U/L,190 U/L, 2.4 mg/L,1.7 mg/L. In B symptom was 260 U/L,192 U/L,2.3 mg/L, 1.7 mg/L. In clinical stage was 252 U/L, 175 U/L, 2.5 mg/L, 1.6 mg/L. In extranodal sites group was 278 U/L,195 U/L,2.4 mg/L,1.8 mg/L.In Karnofsky evaluation group was 250 mg/L,195 mg/L,2.2 mg/L,1.8 mg/L.LDH level of invasive lymphoma was significantly higher than that of indolent ones (median 211U/L,175 U/L,P=0.002),but there were no difference in the 32-MG level (P=0.937). There were no statistical significance about LDH and β2-MG levels in gender and cell type (P>0.05).Overall survival rates were different between the abnormal LDH group and the normal LDH group (χ2=119.029, P<0.001).Overall survival rates were different between the elevated β2-MG group and the normal β2-MG group (χ2 =104.733,P<0.001).Overall survival rates of the abnormal LDH/β2-MG group was significantly lower than that of normal group (x2=192.326,P<0.001).Multivariate analysis in Cox regression showed that LDH,β2-MG,age,clinical stages, extranodal sites, Karnmofsky evaluation and aggressive were independent prognostic factors.Conclusion The level of serum LDH and β2-MG can be taken as an auxiliary clinical index to evaluate the prognosis of the NHL patients.

ABSTRACT

Objective To study clinical characteristics and prognostic factors in systemic anaplastic large cell lymphoma (S-ALCL). Methods Clinical date of 30 systemic ALCL patients from Department Hemotology of Shanxi Cancer Hospital from December 1998 to September 2009 were reviewed. Results The median age of the 30 patients was 36 years old. The male/female ratio was 1.5:1.18 (60.0 %) 18/30 of the patients had B symptoms, 22 (73.3 %) had Ann Arbor stage Ⅲ-Ⅳ, and 18 (60.0 %) had extranodal disease at diagnosis. 14 (46.7 %) had elevated lactate dehydrogenase (LDH) level. The positive rate of ALK was 18 (60.0 %). Compared with ALK negative patients, ALK-positive patients were younger (u = 3.92, P=0.001).ALK expression and LDH level were important prognostic factors by Long-rank test. Conclusion S-ALCL usually occur in younger patients, with good response to chemotherapy and good prognosis. ALK negative and elevated LDH level are correlated to unfavorable prognosis. Combination chemotherapy is the major choice to these patients. High-dose chemotherapy maybe benefit to the patients who have adverse prognostic factors.

ABSTRACT

Objective To compare bone marrow and lymph node biopsy specimens of two kinds of multidrug resistance (MDR) proteins expression and clinical significance in untreated non-Hodgkin lymphoma.Methods We developed multiparameter flow cytometric assay to quantify expression of these multidrug resistance (MDR) proteins in lymph node viable blasts and reverse transcriptase-polymerase chain reaction (RT-PCR) method to semi-quantitate mdrl mRNA of non-Hodgkin lymphomas, including 41 lymph node and 37 bone marrow, and further study of the correlation of the multidrug resistance proteins with general clinical parameters and treatment outcome. Results In two kinds of samples P-gp, MRP and LRP over-expression of three kinds of drug-resistant gene and frequencies are very low. Patients with P-gp expression had a poor outcome of chemotherapy than those without P-gp (P <0.05), Patients with LRP expression had poor outcome of chemotherapy than those without LRP (P <0.01). In the lymph node, P-gp expression was associated with higher clinical stage (P = 0.046), elevated serum lactate dehydrogenase levels (P <0.05). MRP wasn' t associated with higher clinical stage (P =0.369), elevated LDH (P =0.762) and higher malignant degree(P =0.214). LRP expression was associated with higher clinical stage, elevated LDH and higher malignant degree (P <0.05). And in the bone marrow, LRP expression was associated with elevated LDH (P =0.003), but the others have no differences. Conclusion These data suggest that P-gp and LRP expression are important mechanism of drug resistance associated with worse clinical outcome in previously untreated NHL. The use oflymph node biopsy to detect drug-resistant protein can provide more accurate clinical information than that of bone marrow.

ABSTRACT

Objective To test different expression protein markers of the serum from B-cell non-Hodgkin lymphoma(B-cell NHL) between diffuse large B-cell lymphoma(DLBCL) and follicular lymphoma(FL)patients using sudace enhanced laser desorption/ionization-time of flight-mass spectrometry(SELDI-TOF-MS)protein chip technology. Further, to test different expression of the protein markers of B-eell NHL patients after chemical therapy in order to discuss clinical significance. Methods Different expression of protein markers were analysed in serum between 54 B-cell NHL patients and 27 healthy volunteers by using SELDI-TOF-MS WCX-2 pertein chip. Meanwhile different expression of protein markers relative to pathology classification between 23 DLBCL patients and 12 FL patients were screened; and protein markers which affected prognosis of 23 DLBCL patients were screened. Results There were five specific marker proteins in 54 B-cell NHL patients and 27 healthy volunteers. Their relative molecular weights were 7974, 15 938, 3398,8564, and 8692. The protein markers of 7974 and 15 938 were at high level in patients and the protein markers of 3398, 8564 and 8692 were at low level in patients. There were two protein markers which affected the prognosis, with better outcome when the expression of 4795 and 4998 were increased. Conclusion SELDI-TOF-MS protein chip technology is a quick, easy and convenient method, with high-throughput analyzer which can screen several relatively specific protein markers from the serum of patients to diagnose B-cell NHL The relatively specific protein markers can be used to make pathology classification and to judge the prognosis of B-cell NHL, and have better clinical value.

Objective To research correlation of serum protein spectrometry and lymphoma markers for diffuse large B cell lymphoma (DLBCL) patients. Whether there is relative between the protein and prognosis will be further researched. Methods Serum protein spectrometry of 62 DLBCL patients was detected by the SELDI-TOF-MS technique and Weak cation exchange 2 (WCX2) chip. Lactate dehydrogenase (LDH) was detected by biochemistry method. Beta-2-microglobulin (β2-MG) and cancer antigen125(CA125)were detected by enzyme-linked immunosorbent assay (ELISA). The level of LDH, β2-MG and CA125 for DLBCL patients between 11×103~12×103 protein expressed positively and negatively was analyzed. Meanwhile,correlation analysis and survival analysis were done. Results LDH, β2-MG and CA125 in 11×103~12×103protein expressed positive group were (523.30±435.96)U/L, (3.23±1.24)mg/L, (81.07±61.39)U/L respectively,and they were higher than that in negative group (P<0.05). 11×103~12×103 protein was positive correlated to LDH, β2-MG and CA125 (P<0.01). The survival time in 11×103~12×103 protein expressed in positive group,in which median survival time was 11 months, was shorter than that in negative group(P <0.01). The survival time in LDH normal group was longer than that in increased group(P <0.01). The survival time of β2-MG and CA125 had no significant difference between increased group and normal group. Conclusion LDH and 11×103~12×103 protein are expected to be prognosis indicators for DLBCL patients.
