1596 Background: The role of genetic factors in the development of cancer is widely accepted. Previous studies have observed an association between ABO blood group and risk of certain malignancies, including pancreatic and gastric cancer. The data on the role of ABO blood group and Rh factor in lung cancer is limited. Methods: All patients who had Lung cancer (LC) and treated between 2000-2011 at the involved centers with defined ABO/Rh were included in our retrospective reviews of tumor registry records. A group of volunteer healthy blood donors of Turkish Red Crescent between 2004 and 2011 were identified as a control group. The relationship of ABO/Rh with clinical features such as age at diagnosis, histological subtype and sex were evaluated. We compared the distributions of ABO/Rh among 1954 patients and 3,022,883 controls. Among LC patients, differences between each of aforementioned ABO/Rh groups with respect to various clinical features were explored, respectively. Results: Of these patients the median age was 62 (range: 17-90). The 84% of patients were male. Overall distributions of ABO blood groups as well as Rh factor were statistically different between patients (43.6% A, 8.3% AB, 17.3% B, 30.8% O, and 86.3% Rh+) and controls (42.2% A, 7.6% AB, 16.3% B, 33.9% O, and 87.7% Rh+) (p=0,03). In addition, there were statistically significant differences between patients and controls with respect to O vs. nonO (p=0.004) and marginal significance for A vs. nonA (p=0,065), B vs. nonB (p=0,076), and Rh+ vs. Rh- (p=0,057). Among patients, there weren’t statistically significant differences between blood group with respect to sex and age. However there was statistically significant difference between blood group with respect to histology (p=0,001). Although the distribution of A and O were similar according to histology, patients with squamous histology had antigen B more frequently than other histological sub types (p=0,009). Conclusions: In the study populations, ABO blood type was statistically significantly associated with the LC and having blood type other than O increases the risk of LC. Further studies are necessary to define the mechanisms by which ABO blood type may influence breast cancer risk.

1572 Background: The role of genetic factors in the development of cancer is widely accepted. ABO blood type is an inherited characteristic and previous studies have observed an association between ABO blood group and risk of certain malignancies, including pancreatic and gastric cancer. The data on the role of ABO blood group and Rh factor in breast cancer is inconclusive. Methods: All patients who had breast cancer (BC) and treated between 2000-2010 at the Departments of Medical Oncology of both Ankara and Hacettepe Universities (Ankara, Turkey) with defined ABO blood type and Rh factor were included in our retrospective reviews of tumor registry records. A group of volunteer healthy women donors of Turkish Red Crescent between 2004-2011 were identified as a control group, without any matching factors. The relationship of ABO blood types and Rh factor with various prognostic factors such as age at diagnosis, menopausal status, family history of breast cancer, and ER/PR/HER2 status were evaluated from 1740 BC patients. We compared the distributions of ABO blood types, Rh factors among 1740 patients and 204,553 healthy controls. Among BC patients, differences between each of aforementioned ABO blood groups and Rh factors with respect to various prognostic factors were explored, respectively. Results: Overall distributions of ABO blood groups as well as Rh factor were comparable between patients (44% A, 8% AB, 16% B, 32% O, 88% Rh+) and controls (41% A, 8% AB, 16% B, 35% O, 87% Rh+). However, there were statistically significant differences between patients and controls with respect to A vs. nonA (p=0.019) and marginal significance (p=0.051) for O vs. nonO. Among patients, there were statistically significant differences between A and nonA with respect to HER2 (p=0.0421), M stage (p=0.0447), T stage (p=0.0020). Only T stage (p=0.0337) were significantly different between O vs nonO. Grade (p=0.0227) and M stage (p=0.0107) were significantly different between Rh factors. Conclusions: In our study sample, ABO blood type was statistically significantly associated with breast cancer. Additional studies are necessary to determine the mechanisms by which ABO blood type may influence the risk of breast cancer.

AbstractHepatocellular carcinoma (HCC) is one of the most common types of cancer worldwide. There are many factors in the etiology of HCC such as hepatitis B virus (HBV), hepatitis C virus (HCV), alcohol, obesity, smoking and aflatoxin. Many types of cancer are assumed to be associated with ABO blood group and Rhesus factor (RH). In this study we aimed to evaluate the relationship between tumor characteristics and overall survival (OS), ABO blood group and RH factor in patients with HCC. A total of 507 patients with chronic liver disease (252 patients with HCC and 255 patients without HCC) were included in the study. All demographic, clinic and laboratory (biochemical parameters and blood type) features were collected retrospectively. The mean age of the patients was 54.50 ± 9.30. There was no significant difference in both ABO groups and RH factors between the two groups. We found that vascular invasion rate of the tumor was higher in the B blood group and multicentric localization of tumor was significantly higer in patients with positive RH but there was no difference between OS in ABO and RH blood groups. In addition, the tumor was less multicentric in the AB blood group. Blood groups and RH factor can be used to predict the prognosis in cirrhotic patients with HCC.

ABO blood group and body mass index (BMI) have individually been appraised as risk factors for certain diseases. From statistical perspective, it may be important to examine the relationship between the ABO blood antigen and BMI. This cross-sectional study involved 412 participants aged 18 to 46 at the Kwame Nkrumah University of Science and Technology (KNUST), Kumasi. Weight and height of participants were measured for BMI calculation; blood group determination was done using antisera. Blood group O was the most prevalent (51.2%), while Rhesus-positive individuals constituted 90.3%. 6.3% of the participants were obese, while 18.7% were overweight. There was significant (p=0.006) higher prevalence of obesity in females (10.3%) than in males (3.4%). The study did not observe any significant difference by association of ABO blood group with gender (p=0.973), BMI (p=0.307), or Rhesus status (p=0.723). Regarding gender (p=0.400) and BMI (p=0.197), no statistically significant difference was observed between Rhesus blood groups. The prevalence of overweight, obesity, blood type O, and rhesus positive observed among students in this study is largely similar to what has been reported in published studies in Ghana and from other countries. Overweight and obesity were not associated with ABO blood groups or Rhesus in this study.

ABSTRACT Background: Ischemic stroke (IS) is a multifactorial disease that presents high rates of morbimortality in Brazil. Several studies proved that there is a link between the ABO blood group system and the occurrence of thrombotic events. Nonetheless, its association with IS is not well established. Objective: For that reason, the purpose hereof was to investigate the relation between the ABO blood groups and the occurrence of IS in a Brazilian cohort of cerebrovascular diseases. Methods: Five hundred and twenty-nine subjects were included over 12 months, from which 275 presented an IS episode and 254 composed the control group. Blood samples were drawn for direct and reverse serotyping. The control and IS groups were compared regarding the traditional risk factors and the distribution of the ABO blood groups. Results: The IS group presented a higher prevalence of systemic arterial hypertension (SAH), diabetes mellitus, smoking habits, family history, cardiopathy, and sedentary lifestyle in comparison with the control group. The AB blood type prevailed among the patients (5.1 vs. 1.6%; p<0.05) and this group had more SAH cases in comparison with the O type group (92.9 vs. 67.3%; p<0.05). Conclusions: Our results suggest that the occurrence of IS is more frequent among patients of the AB blood type.

Background: Acute myeloid leukemia (AML) is a hematological malignancy characterized by the autonomous growth of immature myeloid cells with impaired differentiation and maturation. Cytokines are low-molecular-weight proteins that play a basic and fundamental role in communication within the immune system. Cytokines induce various effects such as differentiation, proliferation, hematopoiesis, and inflammation of target cells. AML is also closely associated with cytokine networks in terms of proliferation, apoptosis, and differentiation of leukemic cells. Cytokines produced by Th1 involved in cell-mediated immunity are called Th1 cytokines. Th1 cytokine includes TNF-α and IL-2. Several studies have reported that TNF-α is highly expressed in leukemia cells with AML patients. Other studies have also reported that high serum level of TNF-α of AML patients is associated with poor survival outcome. However, the association between Th1 cytokine polymorphisms: TNF-α -857C/T and IL-2-330T/G and the pathogenesis of AML is unclear. Therefore, we investigated the role of these polymorphisms in AML. Materials and Methods: This study included 101 patients with AML [male/female, 56/45; age, 15-86 years; median age, 58 years; MRC classification favorable (n = 38), intermediate (n =56), and adverse (n = 7)] and 202 healthy race-matched controls. All participants provided written informed consent. This study was approved by the Institutional Review Board of Gunma University Hospital. Genotyping was performed by the polymerase chain reaction (PCR)-restriction fragment length polymorphism method. Genotype and allele frequency were compared between patient group and control group by χ2-test. Clinical features were compared using Student's t and χ2 tests. Overall survival (OS) and leukemia free survival (LFS) were calculated using the Kaplan-Meier method. Survival curves were compared using the log-rank test. Analyses were performed using the SPSS software package ver. 25 (IBM, Armonk, NY, USA). P &lt; 0.05 was considered to represent statistical significance. Results: TNF-α -857 C/T nonCC genotype (higher producer type) increases the risk of AML (AML vs. controls = 39.6% vs. 28.2%, OR = 1.67, 95% CI = 1.01-2.75, p = 0.045). Moreover, the frequency of TNF-α -857 C/T T allele (higher producer type) was higher in AML patients compared to controls (AML vs. controls = 24.8% vs. 16.8%, OR = 1.625, 95%CI = 1.078-2.451 p = 0.02). There was no significant difference between AML patients and controls in genotype and allele frequencies of IL-2 -330 T/G. In the analysis of clinical features, the average platelet count was significantly lower in TNF-α -857 C/T TT genotype (higher producer type) (TT vs. nonTT = 2.4±1.4 vs. 4.4±5.9, p &lt; 0.01). TT genotype (higher producer type) was also significantly higher in frequency of MRC classification adverse (TT vs. nonTT = 30.0% vs. 4.4%, p = 0.02) and history of tumor (TT vs. nonTT = 30.0% vs. 6.6%. p =0.04). Moreover, in survival time analysis, patients with TNF-α -857 C/T TT genotype (higher producer type) had significantly shortened OS compared with patients with nonTT genotype (lower producer type) (TT vs. nonTT = 17.2 months vs not reached, p &lt; 0.01). Patients with TT genotype (high producer type) also experienced significantly shortened LFS (TT vs. nonTT = 24.0 months vs not reached, p = 0.04). Furthermore, multivariate analysis of OS revealed TNF-α -857 C/T TT genotype (higher producer type) as an independent prognostic factor (HR = 3.01, 95% CI = 1.04-8.69, p = 0.04), like age and white blood cell count. Conclusion: These results suggest that TNF-α-857 C/T T allele (higher producer type) increases the risk of AML. Furthermore, TNF-α-857 C/T TT genotype (higher producer type) affects the poor prognosis. Therefore, these data suggest the new role of TNF-α polymorphism in AML leukemogenesis.

Introduction: Conflicting evidences exist that ABO blood groups correlate with the susceptibility to COVID-19 and its clinical outcomes. This study aimed to pool available articles that assessed a possible relationship between COVID-19 and ABO blood groups. Materials and methods: A search was conducted in four databases comprising Pubmed/Medline, Google scholar, Journal storage (JSTOR) and African Journals Online (AJOL) for relevant studies available before 25th August 2020 and contained extractable data on ABO blood type distribution and COVID-19 disease. Search terms included a combination of “ABO blood group, and COVID-19, coronavirus, and SARS-COV-2”. Results: Fourteen articles that met study inclusion criteria were selected from a total of five hundred and eighty-five articles identified through database search. The fourteen articles reviewed comprised of a total of 73934 subjects (13189 SARS-COV-2 positive cases and 60745 controls). Overall, the risk of SARS-COV-2 infection was found to be significantly increased in patients with blood group A with ORs: 1.24 (95%Cl: 1.09-1.41, P = 0.001). Additionally, blood group O subjects were seen to have decreased odds of contracting COVID-19 infection (OR: 0.78, 95%Cl: 0.68 – 0.89, P=0.0003). No significant association was found between ABO blood groups and COVID -19 severity and mortality. Conclusions: Blood group A was associated with a higher risk of SARS-COV-2 infection whereas risk of infection was lower in blood group O subjects. No statistical significant association was found between ABO blood groups and COVID-19 severity and mortality. The precise role of ABO blood group in COVID-19 susceptibility, severity and mortality requires further research for clarification.

Lethal Prostate Cancer

69 Background: An individual’s blood group is defined by variability in glycotransferases expressed on red blood cell surface; these ABO antigens are also highly expressed on epithelial cells. Previous studies have suggested associations between ABO blood group and increased risk of epithelial cancers including gastric, pancreatic, and ovarian; however, its relationship with risk of prostate carcinoma, and its aggressiveness remains unclear. Methods: We prospectively evaluated the association between ABO blood group and risk of lethal prostate cancer in the Health Professionals Follow-up Study (HPFS) from 1996 to 2008. Hazard ratios (HRs) and 95% confidence intervals (CIs) were calculated using Cox proportional hazards models with adjustment for other risk factors and prostate-specific antigen testing. Results: During 12 years of follow-up of 26,602 men, 2,703 cases of incident prostate cancer were documented, including 289 lethal cases (prostate cancer death or distant metastases). The frequency of ABO blood type was similar between men who developed prostate cancer (37% A, 7% AB, 13% B, and 43% O) and other participants (37% A, 8% AB, 12% B, and 43% O). On multivariate analysis, blood type was not associated with overall prostate cancer incidence. However, compared to men with blood group O, those with blood group AB were significantly less likely to develop lethal prostate cancer (multivariate-adjusted HR = 0.39 [95% confidence interval {CI} = 0.18-0.85]). There was no association between type B or A compared to O with lethal disease. ABO blood type was not significantly associated with the risk of advanced stage or high-grade cancers (Gleason score 8 to 10). Conclusions: Blood group AB was associated with a lower risk of lethal prostate cancer compared to blood group O. Further studies are needed to replicate these findings and to clarify possible biological mechanisms underlying this association.

Abstract Pancreatic cancer is a lethal and devastating disease in the worldwide. Recognized risk factors for pancreatic cancer include cigarette smoking, obesity, type II diabetes and chronic pancreatitis. Other factors such as variant ABO blood type and Helicobacter pylori may also play an important role in pancreatic carcinogenesis. Recently, growing evidence suggests that the association between bacteria and pancreatic cancer is positive and related immune/inflammation activation and increased nitrosamine exposure may be its potential mechanism. Interestingly, it is debatable whether the relationship of bacteria and pancreatic cancer is causative, reactive or parallel and future studies are in progress. Here we review recent progress in pancreatic cancer and its related bacteria.

ABO blood groups appear to be associated with the risk of SARS-CoV-2 infection, but the underlying mechanisms and their real importance remain unclear. Two hypotheses have been proposed: ABO compatibility-dependence (neutralization by anti-ABO antibodies) and ABO-dependent intrinsic susceptibility (spike protein attachment to histo-blood group glycans). We tested the first hypothesis through an anonymous questionnaire addressed to hospital staff members. We estimated symptomatic secondary attack rates (SAR) for 333 index cases according to spouse ABO blood group compatibility. Incompatibility was associated with a lower SAR (28% vs. 47%; OR 0.43, 95% CI 0.27–0.69), but no ABO dependence was detected in compatible situations. For the second hypothesis, we detected no binding of recombinant SARS-CoV-2 RBD to blood group-containing glycans. Thus, although no intrinsic differences in susceptibility according to ABO blood type were detected, ABO incompatibility strongly decreased the risk of COVID-19 transmission, suggesting that anti-ABO antibodies contribute to virus neutralization.

AbstractIn addition to their major role in transfusion medicine, there is increasing evidence that ABO blood group antigens (complex carbohydrate molecules widely expressed on the surface of red blood cells and several other cell types) are implicated in the development of a wide array of pathologic conditions. In particular, intense research has been dedicated over the last 50 years to the study of the association between non-O blood type and the risk of developing cardiovascular disorders. Several pathways have been hypothesized to explain this relationship, the most reasonable implying the influence of the ABO blood group on circulating plasma levels of von Willebrand factor, factor VIII, and several inflammatory cytokines. This narrative review summarizes the current knowledge on the role of ABO antigens in both venous and arterial thromboses, focusing on their association with clinical scoring systems evaluating thrombotic risk.
