Importance and Risk Prediction of ABO Blood Group and Rh Factor in Papillary Thyroid Cancer

Objective:There are limited data in the literature regarding the potential relationship between thyroid cancer and ABO blood types and Rh factor.The aim of our study was to investigate whether papillary thyroid cancer(PTC)is associated with blood type.Materials and Methods:The present study included patients who pre­sented to Dicle University Faculty of Medicine between June 2009 and December 2020 and were diagnosed with PTC as a result of postoperative(thyroidectomy)histopathological analysis.The control group consisted of individuals whose blood type was analyzed at a random blood center.Results:Of the 223 patients diagnosed with PTC,163(73.1%)were fe­males and 60(26.9%)were males.In the comparison of patients based on ABO blood types and Rh factor,A Rh positive blood type was found 31%less frequently in the PTC group compared with the control group,and thus it was associated with a lower risk of PTC(OR:0.69;95%Confidence In­terval:0.50-0.96,p=0.029).Conclusions:In our study,we found A Rh positive blood type to be signifi­cantly less frequent among patients with PTC.A Rh positive blood type can be considered as a protective factor indicating a reduced risk of PTC.

Significant association between ABO blood group and pancreatic cancer

AIM:To evaluate whether the ABO blood group is related to pancreatic cancer risk in the general population of the United States.METHODS:Using the University of Pittsburgh's clinicalpancreatic cancer registry,the blood donor database from our local blood bank (Central Blood Bank),and the blood product recipient database from the regional transfusion service (Centralized Transfusion Service) in Pittsburgh,Pennsylvania,we identified 274 pancreatic cancer patients with previously determined serological ABO blood group information.The ABO blood group frequency was compared between these patients and 708842 individual,community-based blood donors who had made donations to Pittsburgh's Central Blood Bank between 1979 and 2009.RESULTS:The frequency of blood group A was statistically significantly higher amongst pancreatic cancer patients compared to its frequency amongst the regional blood donors [47.63% vs 39.10%,odds ratio (OR)=1.43,P=0.004].Conversely,the frequency of blood group O was significantly lower amongst pancreatic cancer patients relative to the community blood donors (32.12% vs 43.99%,OR=0.60,P=0.00007).There were limited blood group B (n=38) and AB (n=17) pancreatic cancer patients;the overall P trend value comparing patient to donor blood groups was 0.001.CONCLUSION:The ABO blood group is associated with pancreatic cancer risk.Future studies should examine the mechanism linking pancreatic cancer risk to ABO blood group.

Association of ABO blood groups with the severity of coronary artery disease: a cross-sectional study

Objective To investigate whether ABO blood groups is associated with the severity of coronary artery disease(CAD). Methods Between January 2015 and December 2017, 1425 first diagnosed CAD patients confirmed by selective coronary angiography were recruited into this cross-sectional study, and their baseline characteristics, ABO blood groups, Gensini score were collected. Multiple linear regression analysis was performed to test the association between the severity of CAD and ABO blood groups. Results The Gensini score was significantly higher in the blood group A than in the non-A groups(41.2 ± 32 vs. 38 ± 27;P = 0.026). After adjusting for age, male, smoking, family history of CAD, hypertension, diabetes mellitus and hypercholesterolemia, multivariate linear regression indicated that blood group A was associated with the severity of CAD(β= 3.298, 95% CI: 0.91–6.505, P = 0.044). In diabetes group, A blood type was also associated with increased Gensini score(P = 0.02) after adjusting for age, male, family history of CAD, hypercholesterolemia, smoking and hypertension. Conclusion In this cross-sectional study, the data indicated that blood group A was an independent risk factor of severity of CAD in Chinese population and Chinese patients with type 2 diabetes.

Association of ABO blood group and Plasmodium falciparum malaria in Dore Bafeno Area,Southern Ethiopia

Objective:To assess the distribution of ABO blood group and their relationship with Plasmodium falciparum(P.falciparum) malaria among febrile outpatients who sought medical attention at Dore Bafeno Health Center,Southern Ethiopia.Methods:A total of 269 febrile outpatients who visited Dore Bafeno Health Center,Southern Ethiopia,were examined for malaria and also tested for ABO blood groups in January 2010.The blood specimens were collected by finger pricking,stained with Geimsa,and examined microscopically.Positive cases of the parasitemia were counted.CareStart^(TM) Malaria PflPv Combo was also used to test the blood specimens for malaria.ABO blood groups were determined by agglutination test using ERYCLONE antisera.Data on socio-demographic characteristics and treatment status of the participants were also collected.Chi-square and ANOVA tests were used to assess the difference between frequencies and means,respectively.Results:Out of a total of 269 participants,178(66.2%) febrile patients were found to be infected with Plasmodium parasites,among which 146(54.3%),28(10.4%),and 4(1.5%) belonged to P.falciparum,P.vivax,and mixed infections,respectively.All febrile patients were also tested for ABO blood groups and 51.3%,23.5%,21.9%and 3.3%were found to be blood types of 0,A,B and AB,respectively.Both total malaria infection and P.falciparum infection showed significant association with blood types(P<0.05).The proportion of A or B but not 0 phenotypes was higher(P<0.05) in individuals with P.falciparum as compared with non-infected individuals.The chance of having P.falciparum infection in patients with blood groups A,B and AB was 2.5,2.5 and 3.3times more than individuals showing blood 0 phenotypes,respectively.The mean P.falciparum malaria parasitemia for blood groups A,B,AB,and 0 were 3 744/μ L,1 805/ μ L,5 331/μ L,and1 515/μ L,respectively(P<0.01).Conclusions:The present findings indicate that individuals of blood groups A,B and AB are more susceptible to P.falciparum infection as compared with individuals of blood group O.Nevertheless,further in depth studies are required to clearly establish the role that ABO blood group plays in P.falciparum malaria.

Relationship between ABO blood groups and carcinoma of esophagus and cardia in Chaoshan inhabitants of China

AIM:To study the relationship between ABO blood groups and carcinoma of esophagus and cardia in Chaoshan inhabitants of China, which is a unique Littoral high-risk area of esophageal carcinoma in China. The poor communication and transportation in the past has made Chaoshan a relatively closed area and kept its culture and custure of old China thousand years ago. METHODS: Data on age, sex, ABO blood type and X-ray or pathological diagnose of the patients with carcinoma of esophagus or cardia were collected from the Tumor Hospital. First Affiliated Hospital, Second Affiliated Hospital of Shantou University Medical College; and the Central Hospital of Shantou and the Central Hospital of Jieyang. A total of 6685 patients with esophageal carcinoma (EC) and 2955 patients with cardiac cancer (CC) in Chaoshan district were retrospectively assessed for their association with ABO blood groups. RESULTS: The distribution of ABO blood groups in patients with EC or CC was similar to the normal local population in Chaoshan. However, blood group B in male patients with CC and in the patients with carcinoma in the upper third esophagus was 2.3% and 4.7% higher than the corresponding controls. The relative risk B O was 1.1415 (P【0.05) and 1.2696 (P【0.05), respectively. No relationship was found between ABO blood groups and tumor differentiation. CONCLUSION: ABO blood group B is associated with the incidence of CC in male individuals and carcinoma in the upper third esophagus. The distribution of ABO blood groups varies in the different geographical and ethnic groups. As a result, proper controls are very important for such studies.

ABO blood group is a predictor of survival in patients with laryngeal cancer

Background: Whether the ABO blood group is associated with the survival of patients with laryngeal cancer remains unknown. The purpose of this study was to investigate the association between the ABO blood group and clinico?pathologic characteristics of patients with laryngeal cancer and assess whether the ABO blood group was associated with prognosis.Methods: We analyzed the records of 1260 patients with laryngeal cancer who underwent curative treatment at Sun Yat?sen University Cancer Center between January 1993 and December 2009. The Chi?square test was used to assess the relationship between the ABO blood group and clinicopathologic characteristics. The Kaplan–Meier method was used to estimate 3?, 5?, and 10?year overall survival(OS) rates. The Cox proportional hazards model was used in univariate and multivariate analyses of OS.Results: No signiicant association was found between the ABO blood group and clinicopathologic characteristics except for primary tumor site. The median OS for patients with blood groups A, B, AB, and O were 87.0, 80.0, 90.0, and 72.5 months, respectively. The 3?, 5?, and 10?year OS rates were 82.4%, 76.0%, and 67.5% for patients with blood group A; 77.4%, 69.8%, and 58.4% for patients with blood group B; 82.2%, 73.1%, and 65.6% for patients with blood group AB; and 71.7%, 66.4%, and 55.5% for patients with blood group O, respectively. Univariate and multivariate analyses showed that the ABO blood group had signiicant efects on prognosis in patients with laryngeal cancer.Conclusions: The ABO blood group is associated with survival in patients with laryngeal cancer. Patients with blood group O had signiicantly shorter OS than patients with other ABO blood groups.
