This makes it hard to find a clear link. The multivariate RR of endometrial cancer was 1.94 (95% CI, 1.23-3.08) for women diagnosed with diabetes compared with women without diabetes (Table 2 The multivariable models simultaneously included such variables as BMI and total physical activity, which changed risk estimates of diabetes by ≥5%. Furthermore, we had information on all major potential confounders. Type 1 endometrial cancers are the subject of this chapter. Zhi-Hua Zhang, Pu-Yu Su, Jia-Hu Hao, Ye-Huan Sun, The Role of Preexisting Diabetes Mellitus on Incidence and Mortality of Endometrial Cancer, International Journal of Gynecological Cancer, 10.1097/IGC.0b013e31827b8430, 23 ). IARC. We could adjust only for BMI, and we were unable to control for body fat distribution, which would be more appropriate. eISSN: 1538-7755 Gynecol Oncol. This is the first prospective cohort study showing diabetes to be statistically significantly associated with incidence of endometrial cancer and agrees and extends findings from case-control studies (14, 24-27). 2020 Aug 25;11:568. doi: 10.3389/fendo.2020.00568. Taking hormones after menopause that contain estrogen but not progesterone increases the risk of endometrial cancer. Cancer Epidemiol Biomarkers Prev 2007; 16:276. Would you like email updates of new search results? It increases the risk of colorectal, breast , and bladder cancer by 20% to 50%. Cancer and type 1 diabetes . To provide a quantitative assessment of the association between diabetes and risk of endometrial cancer, we conducted a meta-analysis of case-control studies and cohort studies. The typical age-incidence curve for endometrial cancer shows that most cases are diagnosed after the menopause, with the highest incidence around the seventh decade of life. Hyperinsulinemia may also increase levels of free estrogens through decreasing concentrations of circulating sex hormone–binding globulin (32, 33). Endometrial cancer is the most common gynaecological tumour in developed countries, and its incidence is increasing. Type 2 diabetes and endometrial cancer share some risk factors such as obesity and low physical activity. During a mean follow-up of 36,773 women in the cohort for 7 years (265,648 person-years), 225 endometrial cancer cases were diagnosed. We calculated person-years of follow-up for each woman from the date of return of the questionnaire in 1997 to the date of an endometrial cancer diagnosis, the date of a hysterectomy, the date of death from any cause, the date of migration out of the study area during June 30, 2003 to June 30, 2005 (because for this time, we only have regional information), or the end of follow-up (June 30, 2005), whichever came first. We were also unable to distinguish between type 1 and type 2 diabetes, but subjects with type 1 diabetes are a distinct minority among adult diabetics in Sweden. History of diabetes was associated with a twofold increased risk of endometrial cancer among hypertensive women, but no association was observed among nonhypertensive women. Dates of death or migration from the study area were ascertained through the Swedish Death Register and the National Swedish Population Register, respectively. Diabetes Endometrial cancer may be about twice as common in women with type 2 diabetes. Each year, endometrial cancer develops in about 142 000 women worldwide, and an estimated 42 000 women die from this cancer. Cases were 752 women with incident, histologically confirmed endometrial cancer <75 years of age (median age 60 years, range 28-74) admitted to a network of hospitals in Milan. Parazzini F, La Vecchia C, Negri E, et al. Privacy, Help Diabetes could therefore be an intermediate factor … 2020 Nov 17;17(22):8501. doi: 10.3390/ijerph17228501. Kim S, Park J, Chen Y, Rowe K, Snyder J, Fraser A, Smith K, Deshmukh VG, Newman M, Herget K, Porucznik CA, Ose D, Playdon M, Gaffney D, Hashibe M. Gynecol Oncol. Fader AN, Arriba LN, Frasure HE, von Gruenigen VE. The mean age at diagnosis of endometrial cancer was 68.6 (±9.5) years. We considered the association between diabetes and risk of endometrial cancer using data from a large case-control study conducted in Italy. For endometrial cancer, obesity has been shown to be an effect modifier of the association between diabetes and cancer with a higher risk among women with both obesity and diabetes compared to those with diabetes alone . Endometrial cancer is the fourth most common cancer in women, accounting for approximately 6,000 deaths per year in the United States. Cancer Epidemiology, Biomarkers & Prevention Treatment of Endometrial Cancer in Patient With Diabetes There have been some small, limited studies as well as anecdotal reports that certain alternative or “natural” treatments can help control blood glucose levels in people with Endometrial Cancer and diabetes or … However, a formal test did not show a statistically significant interaction between diabetes and BMI (Pinteraction = 0.25). The physical activity questions were validated by comparing with two 1-week records; Spearman correlation coefficient was 0.7 (29). Diabetes and endometrial cancer: effect modification by body weight, physical activity and hypertension. The statistical significance of interactions was tested by adding an interaction term to the Cox model, simultaneously containing the main variables and age in months. Endometrial cancer may be about twice as common in women with type 2 diabetes. We conducted analyses of diabetes stratifying by BMI and physical activity. All analyses were done using Statistical Analysis System software version 9.1 (SAS Institute, Cary, NC). Furthermore, we had no information on duration of diabetes or treatment given. Clinical Risk and Overall Survival in Patients with Diabetes Mellitus, Hyperglycemia and Glioblastoma Multiforme. We observed an ∼3-fold increased risk for obese women with diabetes comparing with obese women without diabetes. Association of diabetes with risk of endometrial cancer stratified by BMI and physical activity. Diabetes doubles the risk of liver, pancreas, and endometrial cancer. Careers. NOTE: We request your email address only to inform the recipient that it was you who recommended this article, and that it is not junk mail. There was a statistically significant interaction between physical activity and diabetes (Pinteraction = 0.002). In sensitivity analysis, after exclusion of women with missing values of any single covariable included in the additionally adjusted multivariable model, the result did not differ substantially from the original analyses (RR, 1.98; 95% CI, 1.11-3.53). Endometrial cancer is most common in postmenopausal women. Type 2 diabetes was associated with endometrial cancer among women with a body mass index (BMI) (weight (kg)/height (m)(2)) less than 35 but not among women with a BMI of 35 or more. Endometrial cancer is the most common gynecologic malignancy. Interventions to reduce body weight and increase physical activity may have important implications in terms of prevention of endometrial cancer and future management of diabetic subjects. Weight control and physical activity. These observations, if confirmed, are of important clinical significance not only in the prevention of endometrial cancer but also potentially in the management of diabetic subjects, especially those with obesity and low physical activity levels. Subjects with the most unfavorable combination of diabetes with both high BMI and low physical activity had ∼10-fold higher risk in comparison with nondiabetic women with normal weight who were highly physically active. Compared with persons without diabetes, those with diabetes had an adjusted odds ratio of 1.86 (95% confidence interval (CI) 1.37-2.52) for endometrial cancer. Some of the signs and symptoms of Endometrial Cancer in Patient with type 1 and type 2 diabetes … 2006 Jul 1;164(1):56-62. doi: 10.1093/aje/kwj152. A rare type of ovarian tumor that secretes estrogen also can increase the risk of endometrial cancer. If endometrial cancer is not detected early, it can spread (metastasize) from the uterus to neighbouring areas such as the cervix, and further away to the bowels. No consistent interaction or modifying effect was observed for any other covariate. The cancers with the highest increase in risk tended to be different to those noted in type 2 diabetes. Sign In to Email Alerts with your Email Address. A total of 22 cohort and case-control studies were included in this meta-analysis, of which 14 showed statistically significant associations between diabetes and risk of endometrial cancer. In this respect, it is interesting to note that we have recently observed that reduced adiponectin levels are associated with increased risk for endometrial cancer and a combination of obesity with reduced adiponectin levels increases risk even further (i.e., 6-fold; ref. Diabetes and risk of endometrial cancer: a population-based prospective cohort study Cancer Epidemiol Biomarkers Prev, 16 (2007), pp. In contrast, physically active diabetic women did not have significantly increased risk for endometrial cancer compared with women without diabetes; however, this observation was based on a very few cases. 2005 May 15;161(10):939-47. doi: 10.1093/aje/kwi127. 2008 Jun;18(6):492-9. doi: 10.1016/j.annepidem.2007.11.011. Stage 1: Cancer is limited to the uterus. Diabetes shows a supramultiplicative effect with body mass index, but not with physical activity or hypertension. 22) as well as mortality (multivariate RR, 1.33; 95% CI, 0.92-1.90; ref. Furthermore, we evaluated the joint effect of diabetes combined with obesity and low physical activity. Family history Endometrial cancer tends to run in some families. Other characteristics did not differ substantially between diabetics and nondiabetics. In stratified analysis, using as reference group nondiabetic women with low BMI, women with diabetes and high BMI had a >6-fold increased risk. In type 1 diabetes and Endometrial Cancer, symptoms tend to come on quickly and be more severe. Decreased circulating IGF-binding protein-3 levels may also have a direct regulatory role in cell growth control and cancer (43, 44). Grant support: World Cancer Research Fund International, Swedish Cancer Foundation, Swedish Research Council/Longitudinal Studies grant DK58785, Swedish Foundation for International Cooperation in Research and Higher Education, and American Diabetes Association Award. Endometrial cancer is diagnosed most often in postmenopausal women at an average age of 60 years.. From 2000 to 2015, the number of new cases of all types of endometrial cancer has increased slightly each year among non-Hispanic blacks, non-Hispanic Asian/Pacific Islanders, and Hispanic women, but has remained about the same among … Obesity and physical inactivity are two important risk factors for diabetes and also for endometrial cancer. Results from this analysis did not differ substantially from those for the whole cohort (multivariable RR, 1.77; 95% CI, 1.06-2.97, including 193 cases). In conclusion, our results suggest that diabetes may increase risk for endometrial cancer especially when combined with obesity and/or physical inactivity. This study was approved by the Ethics Committees at the Uppsala University Hospital (Uppsala, Sweden) and the Karolinska Institutet (Stockholm, Sweden). The Swedish Cancer Registry and the Regional Cancer Registry have been estimated to be ∼100% complete (30). Friberg E, Mantzoros CS, Wolk A. Diabetes and risk of endometrial cancer: a population-based prospective cohort study. Enter multiple addresses on separate lines or separate them with commas. Our observation that the risk is higher among obese diabetic women than among obese nondiabetic women is in accordance with the results from the previous case-control studies (14, 25, 26) and one cohort study (22). But diabetes is more common in people who are overweight and less active, which are also risk factors for endometrial cancer. Please enable it to take advantage of the complete set of features! Hyperinsulinemia is a hallmark of diabetes, obesity, and physical inactivity, and insulin has been shown to stimulate the growth of endometrial stromal cells by binding to insulin receptors on endometrial cells (31). We did age-adjusted (age in months) and multivariable analyses. Although the possibility of uncontrolled or residual confounding cannot be entirely eliminated, we have adjusted for multiple potential confounders. Accessibility 7 Insulin sensitizers, especially the biguanide metformin, are broadly used for managing patients with PCOS; metformin ameliorates insulin resistance and hyperinsulinemia in these women, but also improves ovulation and menstrual cycle regularity with long-term use. However, most of these studies used case-control study designs and did … Clipboard, Search History, and several other advanced features are temporarily unavailable. Major strengths of our study include its population-based design and the completeness of identification of endometrial cancer cases through the Swedish cancer registries. However, this association has not always been clear as one study reported that a body mass index (BMI) of greater than 35 was not associated with endometrial cancer, while a lower BMI was associated [6]. Future detailed studies of the mechanisms underlying these epidemiologic observations can elucidate further the mechanisms leading to endometrial cancer and could also provide novel therapeutic opportunities. Diabetes could therefore be an intermediate factor in the etiology of endometrial cancer.In conclusion, our results suggest that diabetes may increase risk for endometrial cancer especially when combined with obesity and/or physical inactivity. The main risk for developing endometrial cancer comes from prolonged exposure to excess endogenous or exogenous estrogen in the absence of opposition by progestin. Diabetes and Sarcopenic Obesity: Pathogenesis, Diagnosis, and Treatments. type 2 diabetes and endometrial cancer, finding that the risk of endometrial cancer rises with greater levels of obesity [7, 8]. The relative risks imparted by diabetes are greatest (about twofold or higher) for cancers of the liver, pancreas, and endometrium, and lesser (about 1.2–1.5 fold) for cancers of the colon and rectum, breast, and bladder. Xu WH, Xiang YB, Zheng W, Zhang X, Ruan ZX, Cheng JR, Gao YT, Shu XO. Body mass index (BMI) and other measures of obesity have been associated positively with both diabetes and endometrial cancer. Although surgery, radiotherapy, chemotherapy, and hormone therapy can significantly improve the survival of patients, the treatment of patients with very early lesions and a strong desire to retain reproductive function or late recurrence is still in the early stages. National Library of Medicine Data from a population-based case-control study of Wisconsin women were used to evaluate the relation of diabetes to the risk of endometrial cancer on the basis of body mass index (BMI). Endometrial cancer and obesity: epidemiology, biomarkers, prevention and survivorship. Epub 2019 Dec 12. Weight history and risk of endometrial cancer among Chinese women. The even higher risk observed in obese diabetic women is compatible with the fact that obesity induces both a state of significant hypoadiponectinemia and hyperinsulinemia as well as an excess of circulating bioactive endogenous estrogens due to an increased estrogen production from aromatization of androgens in peripheral fat tissue (48-50) and/or through a decreased production of sex hormone–binding globulin (51). Most epidemiological studies suggested that diabetes is a risk factor for endometrial cancer incidence; for example, a meta-analysis of 16 studies showed that diabetes was statistically significantly associated with an increased risk of endometrial cancer (summary RR 2.10, 95% CI 1.75–2.53), and there was a stronger association with a adjusting for age (RR 2.74, 95% CI 1.87–4.00) (89). Epub 2006 May 4. Diabetes has been associated with a statistically significantly increased risk of endometrial cancer in most, but not all studies. Epub 2005 Oct 28. Am J Epidemiol. Unable to load your collection due to an error, Unable to load your delegates due to an error. As indicated above, impaired glucose tolerance and diabetes are risk factors for the development of endometrial cancer. Also, diabetes is closely related to increased cancer-specific mortality (HR 2.09, 95% CI 1.31–3.35) and mortality from non-canc… World J Diabetes. 8600 Rockville Pike In this population-based prospective cohort study, women with diabetes had a statistically significant ∼2-fold higher risk for developing endometrial cancer. Wang M, Tan Y, Shi Y, Wang X, Liao Z, Wei P. Front Endocrinol (Lausanne). Bethesda, MD 20894, Copyright We also evaluated the joint effect of diabetes combined with obesity and diabetes combined with low physical activity on the risk of endometrial cancer (Table 4 Thus, the higher risk observed among diabetic women could be due to their reduced adiponectin levels as well as increased insulin and IGF-I levels. Endometrial Cancer and Diabetes symptoms vary depending on how much your blood sugar is elevated. Obesity and physical inactivity are two important risk factors for diabetes and also for endometrial cancer. There are several mechanisms that could be potentially involved in the development of endometrial cancer in diabetic women. IARC handbooks of cancer prevention. K05 CA 92002/CA/NCI NIH HHS/United States, N01 HD 2 3166/HD/NICHD NIH HHS/United States, R01 CA 47749/CA/NCI NIH HHS/United States, R01 CA 75977/CA/NCI NIH HHS/United States, R35 CA 39779/CA/NCI NIH HHS/United States. Friberg E, Mantzoros CS, Wolk A. Diabetes and risk of endometrial cancer: a population-based Zhang Y, Liu Z, Yu X, et al. The observation that being obese and having low physical activity is further increasing risk for endometrial cancer in diabetic women provides new opportunities to prevent endometrial carcinogenesis in diabetic subjects by focusing on modifiable predictors of risk, such as body weight reduction and physical activity. Diabetes was associated with a 2-fold increased risk, and combination of diabetes with obesity and low physical activity was associated with a further increased risk for endometrial cancer. The observed associations persisted after finer adjustment for BMI to control for residual confounding. While the link between obesity, type 2 diabetes and endo-metrial cancer … We do not retain these email addresses. Systemic unopposed estrogen therapy increases The prospective nature of the study fulfills the time sequence criterion for causality and makes it highly unlikely that the associations we observed were due to recall or selection biases, which can lead to spurious associations in case-control studies. To determine whether risk of endometrial cancer among women with type 2 diabetes differs with respect to other endometrial cancer risk factors, the authors used data from a population-based case-control study (1,303 cases and 1,779 controls) conducted in western Washington State during 1985-1999. To eliminate potential effects of early undiagnosed endometrial cancer, we repeated our analysis after excluding endometrial cancer cases diagnosed during the first year of follow-up. History of diabetes was associated with a twofold increased risk of endometrial cancer among hypertensive women, but no association was observed among nonhypertensive women. Endometrial cancer survivors of other races (mostly American Indian [37%] and Pacific Islander [40%]) were more likely to be diagnosed with diabetes than white endometrial cancer survivors overall (HR = 1.55, 95%CI = 1.23, 1.94) and in the first year since cancer diagnosis (HR = 2.16, 95%CI = 1.45, 3.21). These results support the hypothesis that type 2 diabetes is associated with endometrial cancer irrespective of the presence of other risk factors for this disease, except possibly hypertension and extreme obesity.
