Abstract
Objectives The aim of this study was to determine the association of “ABO” and “Rhesus” blood groups with incidence of breast cancer. Methods In this study, we identified 70 research documents from data based search engines including “PubMed”, “ISI-Web of Knowledge”, “Embase” and “Google Scholar”. The research papers were selected by using the primary key-terms including “ABO blood type”, “Rhesus” blood type and “breast cancer”. The research documents in which “ABO” and “Rhesus” blood types and breast cancer was debated were included. After screening, we reviewed 32 papers and finally we selected 25 research papers which met the inclusion criteria and remaining documents were excluded. Results Blood group “A” has high incidence of breast cancer (45.88%), blood group “O” has (31.69%); “B” (16.16%) and blood group “AB” has (6.27%) incidence of breast cancer. Blood group “A” has highest and blood group “AB” has least association with breast cancer. Furthermore, “Rhesus +ve” blood group has high incidence of breast cancer (88.31%) and “Rhesus –ve” blood group has least association with breast cancer (11.68%). Conclusion Blood group “A” and “Rhesus +ve” have high risk of breast cancer, while blood type “AB” and “Rhesus –ve” are at low peril of breast cancer. Physicians should carefully monitor the females with blood group “A” and “Rh +ve” as these females are more prone to develop breast cancer. To reduce breast cancer incidence and its burden, preventive and screening programs for breast cancer especially in young women are highly recommended.

Abstract
PURPOSE To describe venous thromboembolism (VTE) rates in patients with pancreatic cancer (PC) during neoadjuvant therapy. METHODS Factors associated with VTE were evaluated using multivariable logistic regression modeling in patients with resectable and BLR PC treated with neoadjuvant therapy between 2009 and 2014. RESULTS Prevalent VTEs were detected in 13 (5%) of the 260 patients. Incident VTEs were detected in 26 patients (10%); 9 (8%) of the 109 resectable and 17 (11%) of the 151 BLR patients (P = 0.53). Of the 26 incident events, 9 (35%) were PEs, 9 (35%) were extremity DVTs, and 8 (31%) involved the SMV/PV. VTEs were catheter-related in 7 (27%) of the 26 patients. Rh(D) antigen positivity was associated with a decreased risk of incident VTE (OR:0.32, 95%CI:0.11-0.85, P = 0.02). Completion of neoadjuvant therapy to include surgery occurred in 176 (75%) of the 234 patients without incident VTE as compared to 14 (54%) of the 26 patients with incident VTE (P = 0.02). The median survival for all 260 patients was 24.3 months: 17.0 months versus 24.6 months for patients who did and did not develop incident VTE during neoadjuvant therapy (P = 0.11). CONCLUSIONS Patients with localized PC who receive neoadjuvant therapy are at significant risk of VTE and thromboprophylaxis may be warranted. J. Surg.

Abstract
BACKGROUND To evaluate whether ABO-Rh blood groups have significance in the treatment response and prognosis in patients with non-metastatic breast cancer. MATERIALS AND METHODS We retrospectively evaluated files of 335 patients with breast cancer who were treated between 2005 and 2010. Demographic data, clinic- pathological findings, treatments employed, treatment response, and overall and disease-free survivals were reviewed. Relationships between clinic-pathological findings and blood groups were evaluated. RESULTS 329 women and 6 men were included to the study. Mean age at diagnosis was 55.2 years (range: 26-86). Of the cases, 95% received chemotherapy while 70% were given radiotherapy and 60.9% adjuvant hormone therapy after surgery. Some 63.0% were A blood group, 17.6% O, 14.3% B and 5.1% AB. In addition, 82.0% of the cases were Rh-positive. Mean follow-up was 24.5 months. Median overall and progression-free survival times were 83.9 and 79.5 months, respectively. Overall and disease-free survival times were found to be higher in patients with A and O blood groups (p<0.05). However rates did not differ with the Rh-positive group (p=0.226). In univariate and multivariate analyses, ABO blood groups were identified as factors that had significant effects on overall and disease-survival times (p=0.011 and p=0.002). CONCLUSIONS It was seen that overall and disease-free survival times were higher in breast cancer patients with A and O blood groups when compared to those with other blood groups. It was seen that A and O blood groups had good prognostic value in patients with breast cancer.

Abstract
BACKGROUND For decades, studies have been performed to evaluate the association between ABO blood groups and risk of cancer. However, whether ABO blood groups are associated with overall cancer risk remains unclear. We therefore conducted a meta-analysis of observational studies to assess this association. MATERIALS AND METHODS A search of Pubmed, Embase, ScienceDirect, Wiley, and Web of Knowledge databases (to May 2013) was supplemented by manual searches of bibliographies of key retrieved articles and relevant reviews. We included case-control studies and cohort studies with more than 100 cancer cases. RESULTS The search yielded 89 eligible studies that reported 100,554 cases at 30 cancer sites. For overall cancer risk, the pooled OR was 1.12 (95%CI: 1.09-1.16) for A vs. non- A groups, and 0.84 (95%CI: 0.80-0.88) for O vs. non-O groups. For individual cancer sites, blood group A was found to confer increased risk of gastric cancer (OR=1.18; 95%CI: 1.13-1.24), pancreatic cancer (OR=1.23; 95%CI: 1.15-1.32), breast cancer (OR=1.12; 95%CI: 1.01-1.24), ovarian cancer (OR=1.16; 95%CI: 1.04-1.27), and nasopharyngeal cancer (OR=1.17; 95%CI: 1.00-1.33). Blood group O was found to be linked to decreased risk of gastric cancer (OR=0.84; 95%CI: 0.80-0.88), pancreatic cancer (OR=0.75; 95%CI: 0.70-0.80), breast cancer (OR=0.90; 95%CI: 0.85-0.95), colorectal cancer (OR=0.89; 95%CI: 0.81-0.96), ovarian cancer (OR=0.76; 95%CI: 0.53-1.00), esophagus cancer (OR=0.94; 95%CI: 0.89-1.00), and nasopharyngeal cancer (OR=0.81; 95%CI: 0.70-0.91). CONCLUSIONS Blood group A is associated with increased risk of cancer, and blood group O is associated with decreased risk of cancer.

Abstract
Background Uruguay exhibits one of the highest rates of breast cancer in Latin America, similar to those of developed nations, the reasons for which are not completely understood. In this study we investigated the effect that ancestral background has on breast cancer susceptibility among Uruguayan women. Methods We carried out a case–control study of 328 (164 cases, 164 controls) women enrolled in public hospitals and private clinics across the country. We estimated ancestral proportions using a panel of nuclear and mitochondrial ancestry informative markers (AIMs) and tested their association with breast cancer risk. Results Nuclear individual ancestry in cases was (mean ± SD) 9.8 ± 7.6% African, 13.2 ± 10.2% Native American and 77.1 ± 13.1% European, and in controls 9.1 ± 7.5% African, 14.7 ± 11.2% Native American and 76.2 ± 14.2% European. There was no evidence of a difference in nuclear or mitochondrial ancestry between cases and controls. However, European mitochondrial haplogroup H was associated with breast cancer (OR = 2.0; 95% CI 1.1, 3.5). Conclusions We have not found evidence that overall genetic ancestry differs between breast cancer patients and controls in Uruguay but we detected an association of the disease with a European mitochondrial lineage, which warrants further investigation.

Abstract
Objectives. The identification of epidemiological factors increasing the risk of endometriosis could shorten the time to diagnosis. Specific blood groups may be more common in patients with endometriosis. Study Design. We designed a cross-sectional study of 633 Caucasian women living in the same geographic area. Study group included 311 patients with histologically proven endometriosis. Control group included 322 patients without endometriosis as checked during surgery. Frequencies of ABO and Rhesus groups in the study and control groups were compared using univariate and multivariate analyses. Results. We observed a higher proportion of Rh-negative women in the study group, as compared to healthy controls. Multivariate analysis showed that Rh-negative women are twice as likely to develop endometriosis (aOR = 1.90; 95% CI: 1.20–2.90). There was no significant difference in ABO group distribution between patients and controls. There was no difference when taking into account either the clinical forms (superficial endometriosis, endometrioma, and deep infiltration endometriosis) or the rAFS stages. Conclusion. Rh-negative women are twice as likely to develop endometriosis. Chromosome 1p, which contains the genes coding for the Rhesus, could also harbor endometriosis susceptibility genes.

Abstract
Background: Previous studies suggest a possible association between ABO blood group and the risk of breast cancer. The aim of this study is to investigate the presence of a possible association between breast cancer and blood groups ABO and Rh. Materials and Methods: 549 women including 173 cases and 376 controls were selected. The case group included patients with breast cancer and the cancer diagnosis was confirmed for all of them. The control group included women with no reports of breast cancer. Blood group sampling of all cases was performed. The obtained information regarding presence or absence of cancer, blood type, age group and type of cancer were analyzed. Results: There is no significant association between blood types ABO (Rh) and the breast cancer. (P > 0.05) It has been found that the prevalence of invasive intraductal carcinoma was 85% among the cases. About 5% of the total diagnosed cancers in the case group were allocated to modularly carcinoma, invasive lobular carcinoma and Paget's disease. There was no relative frequency in specific blood group for these three types of cancer. The blood types ABO (Rh) and breast cancer type showed no significant relation (P = 0.2). Conclusion: According to the obtained results from this study, there was no relative frequency in specific blood group for these three types of cancer and the blood type could not be influenced as a risk factor in breast cancer.

Abstract
BACKGROUND There is a large amount of evidence that the ABO blood group system may play a role in disease etiology. A relationship between ABO and Rhesus blood groups and cancer risk has been demonstrated in a number of studies. However, in relation to gynecological malignancies, these findings are inconsistent and contradictory. AIM To perform a case-control study for analysis of the distribution of ABO and Rh blood antigens among women from South-East Siberia who suffered from ovarian, endometrial and cervical cancer, and to assess the potential role of these antigens in carcinogenesis. DESIGN, SUBJECTS AND METHODS A total of 1,163 cases with ovarian cancer (n=551), endometrial cancer (n=440) and cervical cancer (n=172) were involved in the study. The control group was formed from 22,581 female blood donors. Blood groups were determined through patients medical records and blood donor records. Odds ratios (OR) with 95% confidence intervals (CI) were calculated. The blood group O was defined as the referent group, as it has the greatest frequency in the populations of Southern Siberia. P values less than 0.05 were regarded as statistically significant. RESULTS We found that carriage of non-O blood types increased the risk of ovarian cancer by 40-60%, and the magnitude of this relationship was strongest in women with the AB (IV) blood group. Carriage of the A (II) blood group strongly correlated with an increased risk of ovarian cancer in premenopausal, but not in postmenopausal women. No statistically significant correlations were obtained for endometrial cancer and cervical cancer. Additionally, we did not observe a relationship between Rhesus factor and cancer risk. CONCLUSION We suggest that carriage of non-O blood groups may elevate risk of ovarian cancer and can play a role in its development.

Abstract
AIM Blood group is an important risk factor for some malignancies, including pancreatic and stomach cancer. However, it is unclear whether the risk of breast cancer is higher in any specific ABO blood type. METHODS We searched the electronic database of PubMed, EMBASE, China National Knowledge Infrastructure and the VIP Chinese Journal of Science and Technology for case-control studies about blood type and breast cancer incidence, and a meta-analysis was conducted. RESULTS Fourteen studies were eligible for assessment on the association of breast cancer with different blood types, including 9665 breast cancer patients and 244,768 controls. Relative to blood type O, women with blood type A (odds ratio (OR) = 1.115, 95% confidence interval (CI) 0.992-1.254), B (OR = 0.983, 95% CI 0.915-1.056) and AB (OR = 1.042, 95% CI 0.881-1.231) had the same breast cancer risk. The risk for women with Rhesus-positive (Rh+) was the same as those with Rh-negative (Rh-) (OR = 0.948, 95% CI 0.667-1.348). Among Caucasians, the OR of blood type A was 1.066 (95% CI, 1.001-1.134, P = 0.522 for heterogeneity). CONCLUSION This meta-analysis suggests Caucasians with blood type A may have a higher risk of breast cancer than other Caucasians. No association was found in any other blood type or any other population. Similarly, the Rh factor had no association with the risk of breast cancer.

Abstract
Obese postmenopausal women increase their risk of developing breast cancer (BC), in particular if they display an android-type pattern of adiposity, which is also associated to increased risks of diabetes mellitus, hypertension and cardiovascular disease. In order to explore the associations among anthropometry (body mass index, body composition, somatotype), some specific items of medical history (diabetes, hypertension, dislypidemias, hyperuricemia) and the risk of BC in Uruguayan women, a case-control study was carried out between 2004-2009 at our Oncology Unit. 912 women of ages between 23-69 years (367 new BC cases and 545 non hospitalized, age-matched controls with a normal mammography) were interviewed. Twenty body measurements were taken in order to calculate body composition and somatotype. Patients were queried on socio-demographics, reproductive history, family history of cancer, a brief food frequency questionnaire and on personal history of diabetes, dislypidemias, hyperuricemia, hypertension and gallbladder stones. Uni- and multivariate analyses were done, generating odds ratios (ORs) as an expression of relative risks. A personal history of diabetes was positively associated to BC risk (OR=1.64, 95% CI 1.00-2.69), being higher among postmenopausal women (OR=1.92, 95% CI 1.04-3.52). The risks of BC for diabetes in postmenopausal women with overweight combined with dislypidemia (OR=9.33, 95% CI 2.10-41.5) and high fat/muscle ratio (OR=7.81, 95% CI 2.01-30.3) were significantly high. As a conclusion, a personal history of diabetes and overweight was strongly associated to BC. The studied sample had a subset of high-risk of BC featured by postmenopausal overweight and diabetic women, who also had a personal history of hypertension and/or dyslipidemia. The present results could contribute to define new high risk groups and individuals for primary as well as for secondary prevention, since this pattern linked to the metabolic syndrome is usually not considered for BC prevention.

Abstract
ABO blood type has been associated with risk and survival for several malignancies; however, data for an association with breast cancer are inconsistent. Our study population consisted of Nurses' Health Study participants with self-reported serologic blood type and/or ABO genotype. Using Cox proportional hazards regression, we examined the association between serologic blood type and incident breast cancer among 67,697 women, including 3,107 cases. In addition, we examined the association with ABO genotype in a nested case-control study of 1,138 invasive breast cancer cases and 1,090 matched controls. Finally, we evaluated the association between serologic blood type and survival among 2,036 participants with breast cancer. No clear association was seen between serologic blood type or ABO genotype and risk of total breast cancer, invasive breast cancer or breast cancer subtypes. Compared to women with blood type O, the age-adjusted incidence rate ratios for serologic blood type and total breast cancer were 1.06 (95% CI, 0.98-1.15) for type A, 1.06 (95% CI, 0.93-1.22) for AB and 1.08 (95% CI, 0.96-1.20) for B. In genetic analyses, odds ratios for invasive breast cancer were 1.05 (95% CI, 0.87-1.27) for A/O, 1.21 (95% CI, 0.86-1.69) for A/A, 0.84 (95% CI, 0.56-1.26) for A/B, 0.84 (95% CI, 0.63-1.13) for B/O and 1.17 (95% CI, 0.35-3.86) for B/B, compared to O/O. No significant association was noted between blood type and overall or breast cancer-specific mortality. Our results suggest no association between ABO blood group and breast cancer risk or survival.

Abstract
Drug addiction is a complex disorder that has been shown to have a genetic component like several other diseases. Finding any factor that is associated with higher risk of addiction tendency may influence the strategies of prevention and treatment of drug abuse and also provide an avenue of further research in genetics, immunology, and other related fields. This case-control study aimed at finding the frequency rate of ABO blood groups and Rhesus (Rh) factor among opioid dependents. Therefore, 249 opioid dependents referred to the Drug Quit center at Bam, Iran (case group) were compared with 360 blood donors referred to the Blood Transfusion Center (control group) in regard to the frequency of blood groups and Rh factor. The two groups were matched for demographic features. The odds ratio for AB blood group in addicts was 3.98 compared to non-addicts (p < .001) and the odds ratio of negative Rh in addicts compared to non-addicts was 4.27 (p < .001). According to the findings, in this population the frequency of negative Rh and AB blood group were significantly less than the predictive values. The relationship between opioid use and blood group type requires a cohort study eliminating all extraneous factors in order to be proved.

Abstract
INTRODUCTION Incidence of oesophageal adenocarcinoma (OAC) is increasing rapidly. OAC arises in columnar-lined oesophagus (CLO), a metaplastic change affecting some patients with gastro-oesophageal reflux disease (GORD). As yet there is no reliable method of identifying those at highest risk. Our earlier observation of an association between OAC and blood group O Rhesus negative, if confirmed, may help identify those at greatest risk. AIM AND METHODS To assess the distribution of blood group and Rhesus D (RhD) factor in patients with GORD compared with the blood donating general population. GORD was categorized as nonerosive reflux (NER), erosive oesophagitis, CLO and OAC. The Rotherham Hospital database holds details of all GORD, CLO and OAC patients seen in the Gastroenterology Unit. Blood group information for patients with GORD was obtained from patients' records and the hospital's blood transfusion service. The blood group distribution in the general population was obtained from the National Blood Transfusion Service. The number of expected to observed patients in each blood group for each subtype was compared. RESULTS Two thousand six hundred and ten NER, 2813 erosive oesophagitis, 568 CLO and 73 OAC patients had a recorded blood group. For RhD positive patients observed proportions in each blood group were similar to expected. The most striking difference was the marked excess of OAC in blood group O, Rhesus negative (P=0.002). CONCLUSION CLO patients with blood group O, RhD negative carry a disproportionately higher risk of developing OAC. The mechanism is unknown but the finding has practical application in guiding risk stratification and intensity of surveillance.
