Relationship between cancer and allergy.

e12018 Background: Many studies have suggested an inverse association between allergies and cancer, while others have found no relation between them, and still others have shown an increased risk of cancer in allergy patients. The conflicting findings from prior studies are partially due to the chosen research method, such as different definitions and measures for atopy, in addition to variations in the control of confusion factors, such as smoking and obesity. Objectives: Verify if there is a relation between certain types of cancer and allergies; investigate if there is a difference between individuals with and without cancer in relation to allergies. Methods: Case-control study carried out at the Alberto Cavalcanti Hospital of the Hospital Foundation of the State of Minas Gerais (FHEMIG), Brazil, from 2009 to 2011. The study included patients over 18 years of age, from both genders, who presented a diagnosis of cancer, as compared to healthy individuals, paired by gender and age. An anamnesis was gathered considering the medical history of the allergy, as diagnosed by a doctor, as well as the patients’ habits, associated illnesses, and the use of medications. For cancer patients, data concerning the tumor were recorded. Subsequently, an allergy percutaneous test was performed in each group to detect allergic hyperreactivity toward common inhalable, bacterial, and food antigens within our everyday environment. A blood sample was collected to quantitatively evaluate the eosinophils. Results: Both groups were paired according to interest variables, and eventual deviations were adjusted by means of multivariate analysis. Reports of allergies occurred in 30% of the patients in the cancer group, as compared to 53% in the control group (p<0.05), whereas in the cutaneous tests, a greater positivity occurred in the cancer group (69%) than in the control group (51%, p<0.05). No difference in the eosinophil values could be observed within the groups. Conclusions: Cancer patients present fewer allergies. By contrast, in cancer patients, positive cutaneous tests detected allergies which did not correspond to the clinical findings. Therefore, in cancer patients, the positive cutaneous test for allergies does not present a direct relation to the presence of clinically detectable allergies.

Risk Of Cancer

Introduction: Cervical cancer is the second most common malignancy among women all over the world and a leading cause of death in females. There are known risk factors in this regard including immunosuppression condition like SLE. Screening of women could decrease the incidence of cervical cancer dramatically by detection of early premalignant changes in the tissue. There was significant debate as female with SLE did in fact have an increased risk of cancer compared to the general population. Our study was conducted to determine the prevalence of abnormal cervical smear and colposcopy finding in patients with SLE. Patients and methods: Our study was carried out on 128 participants (64 SLE patients and 64 apparently healthy individuals as a control group). Patients were recruited from Rheumatology, Obstetrics and Gynecology Department of Armed Forces Hospitals of South Region. Gazan, KSA. The study was explained to all patients and informed consent was obtained before enrollment in the study. All patients underwent thorough complete history taking, clinical evaluation, local and bimanual examination, speculum examination with pap smear intake, colposcopy examination to whom have abnormal pap smear patients with suspicious area, multiple biopsies where be taken for histopathologic examination. Results: The results of our study demonstrated that, there is a significant association between cervical cancer and SLE patients (p=0.034). There is a significant association between ASCUS (Atypical squamous cells of undetermined significance) with younger age of marriage (p=0.019) and shorter duration of SLE (0.014). There is a significant association between cervical cancer with coital bleeding and history of cervical lesion (p=0.003). There is a high significant association between cervical cancer (especially ASCUS and CIN II) with passive smoking. Other examined parameters did not show any significant association (p>0.05).

Risk Of Cancer

Abstract Objective Whether anti-seizure medication (ASM) increases the risk for cancer has been debated for decades. While for some ASM, a carcinoma-promoting effect has been suspected, carcinoma-protective effects have been shown for other ASM. However, the issue remains unresolved as data from preclinical and clinical studies have been inconsistent and contradictory. Methods We collected anonymous patient data from practice neurologists throughout Germany between 2009 and 2018 using the IMS Disease Analyzer database (QuintilesIMS, Frankfurt, Germany). People with epilepsy (PWE) with an initial cancer diagnosis and antiepileptic therapy prior to the index date were 1:1 matched with a control group of PWE without cancer according to age, gender, index year, Charlson Comorbidity Index, and treating physician. For both groups, the risk to develop cancer under treatment with different ASMs was analyzed using three different models (ever use vs. never use (I), effect per one (II) and per five therapy years (III). Results A total of 3152 PWE were included (each group, n = 1,576; age = 67.3 ± 14.0 years). The risk to develop cancer was not significantly elevated for any ASM. Carbamazepine was associated with a decreased cancer risk (OR Model I: 0.699, p < .0001, OR Model II: 0.952, p = .4878, OR Model III: 0.758, p < .0004). Significance Our findings suggest that ASM use does not increase the risk of cancer in epilepsy patients.

The progesterone receptor gene (PROGINS) has been identified as a risk modifier for benign and malignant gynecological diseases. The present case-control study is to evaluate the role of the PROGINS polymorphisms, as risk factor, for endometrial cancer development and to investigate the association between these genetics variants and clinical/pathologic variables of endometrial cancer. PROGINS polymorphism was examined in a total of 121 patients with endometrial cancer and 282 population-based control subjects, all located at the same area in São Paulo, SP, Brazil. The genotyping of PROGINS polymorphism was determined by polymerase chain reaction. The frequencies of PROGINS polymorphism T1/T1, T1/T2, and T2/T2 were 82.6%, 14.9%, and 2.5% in the endometrial cancer patients and 78.4%, 21.6%, and 0% in the controls, respectively. The χ2 test showed a higher incidence of the T2/T2 genotype in the endometrial cancer group subjects, these results were statistically different (P= 0.012). However, due to the fact that there were no women in the control group showing homozygosis for the allele T2, the correct evaluation of odds ratio could not be properly calculated. Regarding the clinical and pathologic findings observed within the group of patients with endometrial cancer, there was significant correlation between T1/T2 genotype and the presence of myoma (P= 0.048). No correlations were observed among the other variables. These data suggest that the PROGINS polymorphism T2/T2 genotype might be associated with an increased risk of endometrial cancer.

Objective: After chemotherapy for breast cancer, Black women gain more weight and have an increased mortality rate compared with White women. Our study objective was to compare biomarkers associated with obesity in Black women with and without a history of breast cancer.Design: Case-controlSetting: Academic/federal institutionParticipants: Black women with a history of breast cancer (cases) and age-matched controls.Methods: We compared insulin resistance, inflammation, and lipids in overweight and obese Black women with a history of breast cancer (n=19), age similar controls (n=25), and older controls (n=32). Groups did not differ on mean body mass index (BMI), which was 35.4 kg/m2, 36.0 kg/m2, and 33.0 kg/m2, respectively.Main Outcome Measures: Insulin resistance (HOMA-IR); inflammation (TNF-α, IL-1b, IL-6, IL-8, CRP); lipids (cholesterol, triglycerides).Results: Cases had 1.6 and 1.38 times higher HOMA-IR values compared with age similar and older controls, respectively (P≤.001 for both). TNF-α and IL-1b were significantly higher in cases compared with both control groups (P<.001 for both). IL-6 was also higher in cases compared with age-similar controls (P=.007), and IL-8 was lower in cases compared with older controls (P<.05). Lipids did not differ between cases and either control group.Conclusions: Black women with breast cancer were significantly more insulin resistant with increased inflammation compared not only with age similar controls but with women who were, on average, a decade older. These biomarkers of insulin resistance and inflammation may be associated with increased risk of breast cancer recurrence and require ongoing evaluation, especially given the relatively abnormal findings compared with the controls in this underserved group.

Background: Atrial Fibrillation (AF) is associated with an increased risk of cardioembolic stroke. Previous studies demonstrate that the Left atrial appendage (LAA) is the most common site of intracardiac thrombus, and the LAA morphology alone may determine the risk of stroke. We aimed to determine the association between LAA regional dysfunction using novel, noninvasive, image-based motion-estimation CT (iME) and prior history of stroke in patients with AF. Methods: Among the patients with history of AF referred for ablation who underwent pre-ablation CT with retrospective ECG gating, we identified 18 patients with a prior history of stroke or TIA, and 18 age- and gender-matched controls. The patients in AF at the time of CT were excluded. Four-dimensional motion vector field was estimated from reconstructed CT images using iME at every 5% RR interval. To assess myocardial deformation, area change ratio and area change rate were calculated over the endocardial surface of the LA and LAA. Univariate and multivariate comparisons were made by using binary logistic regression model. Results: A total of 36 patients (mean age 67.6 ± 8.1 years, 66.7% male, 16.7% persistent AF) were included in the study. Univariate analysis showed that the LA pre-atrial contraction area change ratio and LAA maximum area change ratio were significantly lower (P= 0.02 and 0.04, respectively) in the stroke/TIA group compared to the control group. These changes remained statistically significant in multivariate analysis (P=0.03 and 0.04, respectively) after adjusting for age, sex, body mass index, LV ejection fraction, type of AF, and CHADS score. Conclusions: LAA regional dysfunction is associated with stroke/TIA in patients with AF. LAA regional dysfunction detected by iME could represent a marker for stroke and a possible therapeutic target.

Abstract Context.—Forensic pathologists regularly investigate the deaths of individuals with a history of drug abuse. Autopsy, including toxicology testing, reveals no cause for death in a subset of this cohort. Objective.—To determine whether deaths with an undetermined cause and manner of death are associated with a history of drug abuse. Design.—Retrospective matched case-control study of 52 decedents whose cause of death remained undetermined following autopsy, matched 1:2 to a control group of living patients admitted for cholecystectomy according to age and date of death or procedure. Results.—Individuals whose cause of death was undetermined were 5.3 times (95% confidence interval, 1.9– 14.5) more likely to have a history of drug abuse than were patients with cholecystitis. Conclusions.—Decedents with a history of chronic drug abuse appear to be at an increased risk of dying by their chronic drug abuse, even in the absence of any anatomical or toxicologic finding at autopsy to account for death.

AimsTo investigate the association between incident retinal vein occlusion (RVO) and the subsequent development of cancer.MethodsIn this nationwide population-based retrospective study using 2002–2013 National Health Insurance Service database which covers the entire South Korean population, 186 701 incident RVO patients and their 1:1 propensity-score matched controls were included. We defined the fixed cohort from January 1st, 2004 to December 31st, 2013; the cohort included patients who suffered incident RVO after entering the cohort and their matched controls, and excluded patients having any cancer history before entering the cohort. The association of RVO and cancer was assessed by time-varying covariate Cox regression models; Model 1 included RVO as a time-varying covariate, Model 2 included Model 1 plus demographic information and Model 3 included Model 2 and comorbidities.ResultsRVO was associated with an increased risk of subsequent cancer (HR=1.29; 95% CI, 1.26–1.31 in Model 1), which was consistent in Models 2 and 3. The incidence rate of overall cancer during the study period was 25.55 (95% CI, 25.19–25.91) per 1000 person-years in the RVO group and 18.62 (95% CI, 18.46–18.79) per 1000 person-years in the control group. In the subgroup analysis, haematological malignancies showed the highest association with RVO (HR=1.65; 95% CI, 1.49–1.83).ConclusionPatients with RVO have an increased risk of subsequent cancer development even after adjusting for demographic factors and comorbidities. Further study is warranted to elucidate these associations to provide proper recommendations for RVO patients regarding the cancer screening.

Risk Of Cancer

Venous thromboembolism (VTE) is frequent among patients with cancer. Ambulatory cancer patients starting chemotherapy have a 5% to 10% risk of cancer associated thrombosis (CAT) within the first year after cancer diagnosis. This risk may vary according to patient characteristics, cancer location, cancer stage, or the type of chemotherapeutic regimen. Landmark studies evaluating thrombophrophylaxis with low molecular weight heparin (LMWH) for ambulatory cancer patients have shown a relative reduction in the rate of symptomatic VTE of about one half. However, the absolute risk reduction is modest among unselected patients given a rather low risk of events resulting in a number needed to treat (NNT) of 40 to 50. Moreover, this modest benefit is mitigated by a trend towards an increased risk of bleeding, and the economic and patient burden due to daily injections of LMWH. For these reasons, routine thromboprophylaxis is not recommended by expert societies. Advances in VTE risk stratification among cancer patients, and growing evidence regarding efficacy and safety of direct oral anticoagulants (DOACs) for the treatment and prevention of CAT have led to reconsider the paradigms of this risk–benefit assessment. This narrative review aims to summarize the recent evidence provided by randomized trials comparing DOACs to placebo in ambulatory cancer patients and its impact on expert recommendations and clinical practice.

Aims and background The enzyme cytochrome P450 plays an important role in the metabolization and detoxification of various compounds. CYP1A1 is a polymorphic enzyme and some of its alleles have been correlated with an increased risk of developing various types of cancer. The aim of this study was to investigate the incidence of the polymorphism A→G (Ile462Val, exon 7) in colorectal cancer patients and the correlation of this polymorphism with others risk factors. Patients and methods 114 Brazilian patients with colorectal cancer were matched by age and sex to 114 healthy individuals. DNA was extracted from peripheral blood and the genotypes of the polymorphisms were assessed by PCR-restriction fragment length polymorphism. Results In the case group 64 subjects were male, 53 were alcohol users and 68 were smokers. In the control group 61 were male, 67 were alcohol users and 53 smokers. There were 14 subjects with wild-type homozygous A/A, 97 with heterozygous A/G, and 3 with homozygous mutated G/G in the cancer group versus 81 subjects with wild-type homozygous A/A and 33 with heterozygous A/G in the control group. The presence of the G allele (OR 5.14, 95%CI 3.15–10.80) was associated with an increased risk of colorectal cancer (p=0.001). The prevalence of smokers was higher in the cancer group (p=0.047, OR 1.71, 95%CI 1.03–3.11). Conclusion These results suggest a positive association between the A→G polymorphism and the risk of colorectal cancer. In addition, smoking was also a colorectal cancer risk. We did not find any correlation between this polymorphism and sex, grade of differentiation, stage, or evolution of the disease.
