ABO Blood Group Differentials on Survival in Hepatocellular Carcinoma Patients Treated with Chemoembolization

Background: The association between ABO blood group and the prognosis of hepatocellular carcinoma (HCC) remains unclear. We investigated the impact of ABO blood groups as a prognostic factor in HCC patients treated with transarterial chemoembolization (TACE). Materials and methods: We revisited records of all HCC patients who underwent TACE between January 2007 and December 2019 at a tertiary care hospital. The inclusion criteria were HCC patients, Child-Pugh score A5-B7, and treated with TACE monotherapy. The baseline characteristics of each patient were compared against their blood group and the survival analysis was carried out using Cox’s regression. With Bonferroni adjustment for multiple comparisons, P-values <.0125 were considered statistically significant. Results: Of 211 eligible patients, the frequencies of blood groups O, A, B, and AB were 89, 54, 56, and 12, respectively. Their respective months of median survival were 41, 20, 21, and 42. After adjustments in the six-and-twelve criteria and Child-Pugh scores, and using blood group O as the referent group, the coefficients (SE) of groups A, B, and AB were 0.69 (0.24), 0.47 (0.23), and 0.49 (0.49), respectively. A significant difference in survival was found only between patients with blood group O vs A (hazard ratio, 2.00; confidence interval, 1.25-3.21). Conclusions: ABO blood group is associated with the prognosis of HCC patients treated with TACE monotherapy. In our data, patients with blood group O tended to have the best survival. However, only blood group A patients had a significantly shorter survival rate comparing to blood group O.     

Prognostic Values of Various Clinical Factors and GeneticSubtypes for Diffuse Large B-cell lymphoma Patients: ARetrospective Analysis of 227 Cases

Aim: To analyze the significance of different clinical factors for prognostic prediction in diffuse large B-celllymphoma (DLBCL) patients. Methods: Two hundred and twenty-seven DLBCL patients were retrospectivelyreviewed. Patients were managed with cyclophosphamide, doxorubicin, vincristine, and prednisone (CHOP)regimen or rituximab plus the CHOP (RCHOP) regimen. Results: Lactate dehydrogenase (LDH), β2-microglobulin (β2-M), B symptoms, Ann Arbor stage and genetic subtypes were statistically relevant in predictingthe prognosis of the overall survival (OS). In the CHOP group, the OS in patients with germinal center B-celllike(GCB)(76.2%) was significantly higher than that of the non-GCB group (51.9%, P=0.032). With RCHOPmanagement, there was no statistical difference in OS between the GCB (88.4%) and non-GCB groups (81.9%,P=0.288). Conclusion: Elevated LDH and β2-M levels, positive B symptoms, Ann Arbor stage III/IV, and primarynodal lymphoma indicate an unfavorable prognosis of DLBCL patients. Patients with GCB-like DLBCL have abetter prognosis than those with non-GCB when treated with the CHOP regimen. The RCHOP treatment withthe addition of rituximab can improve the prognosis of patients with DLBCL.

目的分析弥漫性大B细胞淋巴瘤（DLBCL）患者的病理学特征以及影响其预后的相关因素。方法采用单因素及Cox多因素分析方法,对影响DLBCL预后的相关因素进行分析。结果60例DLBCL患者中共有47例（78．33％）侵犯淋巴结,13例（21．67％）结外侵犯。经单因素分析显示,影响DLBCL患者的预后因素包括年龄、临床分期、PS分级、结外病灶数、血清LDH、近期疗效。经Cox多因素分析显示患者年龄、近期疗效、临床分期是影响患者预后的独立危险因素。根据国际预后指数（IPI）将患者分为低危组、低中危组、高中危组及高危组,各组5年生存率分别为70．59％（12／17）、57．14％（12／21）、41．67％（5／12）、10．00％（1／10）,差异有统计学意义（P〈0．05）。联合治疗DLBCL患者的5年生存率显著高于单纯性放化疗或手术治疗患者。结论影响DLBCL患者预后的独立因素包括年龄、近期疗效、临床分期,采用多种方式联合治疗的方案能提高DLBCL患者临床治愈率。     

ABO Blood Group,Epstein-Barr virus Infection and Prognosis of Patients with Non-metastatic Nasopharyngeal Carcinoma

Background: A prior study showed blood type A/AB to be associated with an increased risk of nasopharyngeal carcinoma (NPC) compared to subjects with blood type O. However, the relationship between ABO blood groups and prognosis of NPC patients is still questionable. In addition, whether Epstein-Barr virus (EBV) infection is associated with prognosis of NPC patients with different ABO blood groups is unclear. Materials and Methods: We conducted univariate and multivariable Cox regression analyses based on a consecutive cohort of 1,601 patients to investigate the above issues. Results: There was no significant difference in overall survival (OS) between different ABO blood groups (p=0.629), neither between A vs. non-A blood groups (p=0.895) nor AB vs. non-ABblood group (p=0.309) in univariate analyses and after adjusting for other factors. Interaction tests revealed that high immunoglobulin A against Epstein-Barr virus viral capsid antigen (VcA-IgA) level was associated with a favorable prognosis in male patients with UICC stage II disease who had an A blood type (p=0.008), compared with those with non-A blood type. In addition, male patients with an A blood group with a high blood lymphocyte level showeda tendency towards better survival in UICC stage III (p=0.096). Conclusions: ABO blood group status is not associated with the prognosis of patients with NPC. Additionally, blood group A male NPC patients with high VcA-IgA level or high blood lymphocyte counts might be correlated with a favorable prognosis in UICC stage II or III, respectively.

Prognostic Significance of BCL-2 and BCL-6 Expression in MYC-positive DLBCL

Background

Double-expression lymphoma (DEL) is a rare subgroup of diffuse large B-cell lymphoma (DLBCL), which has coexpression of MYC and BCL-2. Coexpression of MYC and BCL-2 is considered a prognostic marker portending poor outcomes. However, the prognostic effect of BCL-2 and BCL-6 expression in DLBCL remains controversial.

Survival Disparities by Insurance Type for Patients Aged 15–64 Years With Non‐Hodgkin Lymphoma

Background.

New treatment options and supportive care measures have greatly improved survival of patients with non-Hodgkin lymphoma (NHL) but may not be affordable for those with no insurance or inadequate insurance.

Methods.

Using data from the Surveillance, Epidemiology, and End Results database, we estimated overall and cause-specific survival according to insurance status within 3 years after diagnosis of patients diagnosed with NHL in the U.S. in the period 2007–2011. Because NHL is a heterogeneous condition, we also examined survival in diffuse large B-cell lymphoma (DLBCL).

Results.

Survival was higher for patients with non-Medicaid insurance compared with either uninsured patients or patients with Medicaid. For patients with any NHL, the 3-year survival estimates were 68.0% for uninsured patients, 60.7% for patients with Medicaid, and 84.9% for patients with non-Medicaid insurance. Hazard ratios (HRs) for uninsured and Medicaid-only patients compared with insured patients were 1.92 (95% confidence interval [CI]: 1.76–2.10) and 2.51 (95% CI: 2.36–2.68), respectively. Results were similar for patients with DLBCL, with survival estimates of 68.5% for uninsured patients (HR: 1.78; 95% CI: 1.57–2.02), 58%, for patients with Medicaid (HR: 2.42; 95% CI: 2.22–2.64), and 83.3% for patients with non-Medicaid insurance. Cause-specific analysis showed survival estimates of 80.3% for uninsured patients (HR: 1.83; 95% CI: 1.62–2.05), 77.7% for patients with Medicaid (HR: 2.23; 95% CI: 2.05–2.42), and 90.5% for patients with non-Medicaid insurance.

Conclusion.

Lack of insurance and Medicaid only were associated with significantly lower survival for patients with NHL. Further evaluation of the reasons for this disparity and implementation of comprehensive coverage for medical care are urgently needed.     

Evaluation of BCL6 and MUM1 Expression in Patients with Diffuse Large B cell Lymphoma and their Correlations with Staging and Prognosis in Iran

Background: Diffuse large B-cell lymphoma (DLBCL) is the most common form of non-Hodgkins lymphoma(NHL), accounting for approximately 25% of NHL cases. The aim of this study was to evaluate the associationbetween the BCL6 and MUM1 gene expression and patient prognosis and stage. Materials and Methods: Afterethical approval, in a cross-sectional study, tissue samples of 80 patients with diffuse large B-cell lymphoma wereanalyzed for BCL6 and MUM1 gene expression. Immunohistochemical staining was performed with division intocategories of 0-5%, 5-25%, 26-50%, 51-75% and more than 75%. Other clinical and histological information suchas lymph node involvement, T-stage, B symptoms and patient outcome were also recorded. Data were analyzedwith SPSS version 16 and a P-value less than 0.05 was considered significant. Results: The patient mean agewas 46.9±10.5 years (47.6±10.7 and 46.1±9.6 for males and females, respectively). A significant association wasseen between lymphoma stage and BCL6 (p=0.045) but not MUM1 expression (p=0.09). However, the latterwas associated with mortality (p=0.006) as was also the BCL6 level (p=0.006). Conclusions: : Overexpression ofMUM1 and BCL6 is associated with poor prognosis in patients with diffuse large B-cell lymphoma.     

Prognostic value of ABO blood group in southern Chinese patients with established nasopharyngeal carcinoma

Background:

ABO blood group is associated with aetiology of nasopharyngeal carcinoma (NPC); however, the effect of it on survival of patients diagnosed with NPC has not been explored.

Methods:

We retrospectively analysed two cohorts of southern Chinese patients with WHO histological type III: intensity-modulated radiotherapy (IMRT) cohort, 924 patients; and conventional radiotherapy (CRT) cohort, 1193 patients. Associations of ABO blood group with survival were estimated using Cox regression.

Results:

In IMRT cohort, we observed significant associations of blood type A with overall survival (OS) and distant metastasis-free survival (DMFS), compared with type O, after adjusting for prognostic factors. Compared with non-A blood types (B, AB, and O), type A patients had significantly lower OS and DMFS (adjusted hazard ratio (HR)=1.49, 95% CI 1.03–2.17, P=0.036; HR=1.68, 95% CI 1.13–2.51, P=0.011, respectively); similar results were obtained in CRT cohort. Subgroup analyses of the entire population showed that lower OS conferred by blood type A was not significantly modified by age, smoking status, drinking status, immunoglobulin A against Epstein–Barr virus viral capsid antigen (VCA-IgA) titre, or chemotherapy; however, lower OS was not observed in female patients or patients with early clinical stage disease.

Conclusion:

ABO blood group is associated with survival in NPC; patients with blood type A had significantly lower OS and DMFS than patients with non-A blood types.

Diffuse large B-cell lymphoma arising in nodular lymphocyte predominant Hodgkin lymphoma: a report of 21 cases from the Nebraska Lymphoma Study Group

We sought to investigate the clinical characteristics and pathologic features and survival outcome of patients with diffuse large B-cell lymphoma (DLBCL) arising in nodular lymphocyte predominant Hodgkin lymphoma (NLPHL), since controversy regarding their prognosis exists in the literature. Twenty-one patients with DLBCL arising either concurrently with (n = 7) or subsequent to (n = 14) a diagnosis of NLPHL were identified in the Nebraska Lymphoma Study Group Registry. The clinical and pathologic features of the cases were evaluated, and survival analysis was performed from the time of diagnosis of DLBCL. The median time to the development of DLBCL in those with prior NLPHL was only one year (range, 0.5 - 24 years). The median age of the patients at the time of diagnosis of DLBCL was 46 years (range, 18 - 72 years) and the male to female ratio was 17 : 4. Ten patients presented with nodal DLBCL only, 6 patients presented with both nodal and extranodal involvement, and 5 patients presented with only extranodal DLBCL. Eleven patients had limited stage (I/II) disease and 10 had advanced stage (III/IV) disease. The median overall survival (OS) and failure-free survival (FFS) of the entire group was 35 months and 11 months, respectively, and the predicted 5-year OS and FFS was 31% and 18%, respectively. There were no significant differences in the survival outcomes between patients with DLBCL arising in NLPHL and age- and sex- matched patients with de novo DLBCL. Our findings suggest that patients with DLBCL arising in NLPHL have a prognosis similar to those with de novo DLBCL and should be treated aggressively.
