Low adiponectin levels are not only associated with higher levels of circulating estradiol and hyperinsulinemia/insulin resistance (46) but may also directly alter cell proliferation/apoptosis and angiogenesis by a process that involves members of the caspase group of apoptotic enzymes (47). Overall diabetes was positively associated with endometrial cancer risk in both age-adjusted and multivariate analyses adjusting for confounders, such as BMI and total physical activity. Endometrial cancer: A review and current management strategies: Part I ... sociation between diabetes and endometrial cancer has been reported [8]. To estimate the risk of endometrial cancer, we used Cox proportional hazards regression models. The costs of publication of this article were defrayed in part by the payment of page charges. Type 2 diabetes mellitus (T2DM), a chronic disease increasing rapidly worldwide, is well established as an important risk factor for various types of cancer. Dates of death or migration from the study area were ascertained through the Swedish Death Register and the National Swedish Population Register, respectively. Adjusting for BMI as a categorical (quartiles) variable compared with as a continuous did not change the risk estimate (RR, 1.93; 95% CI, 1.22-3.06). 8600 Rockville Pike Epub 2019 Dec 12. 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.

National Library of Medicine Saed L, Varse F, Baradaran HR, Moradi Y, Khateri S, Friberg E, Khazaei Z, Gharahjeh S, Tehrani S, Sioofy-Khojine AB, Najmi Z. BMC Cancer. But diabetes is more common in people who are overweight and less active, which are also risk factors for endometrial cancer. Diabetes has been associated with a statistically significantly increased risk of endometrial cancer in most, but not all studies. IARC handbooks of cancer prevention. BACKGROUND: A growing body of evidence suggests that diabetes is a risk factor for endometrial cancer incidence. As indicated above, impaired glucose tolerance and diabetes are risk factors for the development of endometrial cancer. A rare type of ovarian tumor that secretes estrogen also can increase the risk of endometrial cancer. endometrial cancer that may be related to concurrent obe-sity (19, 20), although an independent association between diabetes and endometrial cancer has been reported (21). We have recently reported that obesity is closely associated with lower circulating levels of an endogenous insulin sensitizer, adiponectin (45), which in turn leads to type 2 diabetes and hyperinsulinemia. Association of diabetes combined with obesity and of diabetes combined with low physical activity (inactivity) with risk of endometrial cancer. 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). Furthermore, we had information on all major potential confounders. 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. ). Cancer and type 1 diabetes . 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]. Physically active diabetics were not at increased risk for endometrial cancer. Controlling for competing causes of death in survival analyses may therefore be crucial in order to understand the complex relationship between obesity, diabetes and endometrial cancer survival. Each year, endometrial cancer develops in about 142 000 women worldwide, and an estimated 42 000 women die from this cancer. 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 summary of RR for all 9 cohort studies was 1.56 (95% CI 1.21–2.01), and it was 1.85 (95% CI 1.53–2.23) for 13 case control studies. 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. Completion of the self-administered questionnaire indicated informed consent to participate in this study. 35, 36).

It is not clear whether or not the association of diabetes with endometrial cancer is explained entirely by obesity. Friberg E, Mantzoros CS, Wolk A. Diabetes and risk of endometrial cancer: a population-based prospective cohort study. While the link between obesity, type 2 diabetes and endo-metrial cancer … History of diabetes was associated with a twofold increased risk of endometrial cancer among hypertensive women, but no association was observed among nonhypertensive women. As indicated above, impaired glucose tolerance and diabetes are risk factors for the development of endometrial cancer.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.16Metformin not only suppresses glucose production in the liver, but also has demonstrated beneficial effects in other ty… ISSN: 1055-9965. Diabetes and risk of endometrial cancer: a population-based prospective cohort study Cancer Epidemiol Biomarkers Prev, 16 (2007), pp. 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). We did age-adjusted (age in months) and multivariable analyses. Endometrial cancer is the fourth most common cancer in women, accounting for approximately 6,000 deaths per year in the United States. Some of these families also have a higher risk for colon cancer5. We considered the association between diabetes and risk of endometrial cancer using data from a large case-control study conducted in Italy. Estrogens have in turn been shown to increase endometrial cancer risk by stimulating proliferation of endometrial cells (34) when unopposed by progesterone (especially in postmenopausal women; refs. Obese, physically inactive, diabetic women (including 9 endometrial cancer cases) had a RR of 9.61 (95% CI, 4.66-19.83) in age-adjusted analysis when compared with nondiabetic, nonobese women with high physical activity (including 75 endometrial cancer cases). Gynecol Oncol. Am J Epidemiol. 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. Finally, hyperinsulinemia through decreasing levels of insulin-like growth factor (IGF)-binding protein-1 and IGF-binding protein-3 increases circulating free IGF-I, which by binding and activating IGF-I receptors in the endometrium stimulates cell proliferation (37-42). Epub 2009 Apr 29. Baseline characteristics of women according to diabetes diagnosis, Association of diabetes with the risk of endometrial cancer. Diabetes and Risk of Endometrial Cancer: A Population-Based Prospective Cohort Study, Early-Life Risk Factors for Breast Cancer, Sugary Drink Consumption and Colorectal Cancer Risk, Cancer Epidemiology, Biomarkers & Prevention. 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. No consistent interaction or modifying effect was observed for any other covariate. We conducted analyses of diabetes stratifying by BMI and physical activity. Each year, endometrial cancer develops in about 142 000 women worldwide, and an estimated 42 000 women die from this cancer. The observed associations persisted after finer adjustment for BMI to control for residual confounding. A Review of the Current Literature. Weight control and physical activity. 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. Risk factors for the incidence of endometrial cancer according to the aggressiveness of disease. Clipboard, Search History, and several other advanced features are temporarily unavailable. 22) as well as mortality (multivariate RR, 1.33; 95% CI, 0.92-1.90; ref. Sign In to Email Alerts with your Email Address. A growing body of evidence suggests that diabetes is a risk factor for endometrial cancer incidence. Cancer Epidemiology, Biomarkers & Prevention Furthermore, we had no information on duration of diabetes or treatment given. Diabetes could therefore be an intermediate factor in the etiology of endometrial cancer. Enter multiple addresses on separate lines or separate them with commas. 2006 Jul 1;164(1):56-62. doi: 10.1093/aje/kwj152. However, most of these studies used case-control study designs and did … 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. It is the fourth most common cancer in women in the United States after breast, lung, and colorectal cancers. 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). The cancers with the highest increase in risk tended to be different to those noted in type 2 diabetes. 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. There was a statistically significant interaction between physical activity and diabetes (Pinteraction = 0.002). The most frequently occurring histological subtype is endometrioid adenocarcinoma. Diabetes and Sarcopenic Obesity: Pathogenesis, Diagnosis, and Treatments. Table 1 This study has important public health implications in terms of endometrial cancer prevention, given the continuously increasing prevalence of obesity and diabetes mainly due to inactivity and unhealthy diets, in Western societies. The lack of increased risk observed among physically active diabetics observed in our study may reflect the increased insulin sensitivity found in physically active women (53) and/or a shift in body composition containing less body fat and visceral adipose tissue (6, 7). The main risk for developing endometrial cancer comes from prolonged exposure to excess endogenous or exogenous estrogen in the absence of opposition by progestin. History of type 2 diabetes was associated with endometrial cancer (odds ratio (OR) … Whereas taking estrogen alone increases the risk of endometrial cancer, taking both estrogen and a progestogen in combination, as in most birth control pills, decreases the risk. Am J Epidemiol. Previous studies conducted on the association between diabetes and the risk of endometrial cancer have reported controversial results that have raised a variety of questions about the association between diabetes and the incidence of this cancer. Meta-analysis of intrauterine device use and risk of endometrial cancer. Epub 2008 Feb 8. All analyses were done using Statistical Analysis System software version 9.1 (SAS Institute, Cary, NC). When stratifying on total physical activity, the excess risk for endometrial cancer associated with diabetes and low physical activity was statistically significantly 3-fold higher compared with nondiabetic women with high physical activity. Links between type 1 diabetes and cancer are not so well recorded but it appears there is also an increase in risk of cancers for people with type 1 diabetes . More years of menstruation. The risk associated with type 2 diabetes appeared not to vary greatly with respect to other endometrial cancer risk factors. We used age-specific (<53, 53-65, and >65 years) portion sizes that were based on mean values obtained from 213 randomly chosen women from the study area who weighed and recorded their foods during four 1-week periods 3 to 4 months apart.3. If confirmed by other studies and in other populations, these data may prove of major public health significance given the increasing prevalence of obesity, physical inactivity, and diabetes in Western societies. Type 2 diabetes and cancer share many risk factors, but potential biologic links between the two diseases are incompletely understood. 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). 2009 Jul;114(1):121-7. doi: 10.1016/j.ygyno.2009.03.039. Similarly, women classified as having low physical activity had an ∼3-fold increased risk if they had diabetes. Studies evaluating this association for other cancer sites are lacking. Cancer Epidemiol Biomarkers Prev 2007; 16:276. 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. Copyright © 2021 by the American Association for Cancer Research. Taking hormones after menopause that contain estrogen but not progesterone increases the risk of endometrial cancer. We also did analysis examining the joint effect of diabetes combined with obesity and diabetes combined with low physical activity (inactivity). One limitation of our study is that identification of diabetic women in the cohort was partly based on self-reports, which might lead to underestimation of the true prevalence of diabetes. Also, diabetes is closely related to increased cancer-specific mortality (HR 2.09, 95% CI 1.31–3.35) and mortality from non-canc… Decreased circulating IGF-binding protein-3 levels may also have a direct regulatory role in cell growth control and cancer (43, 44). Hyperinsulinemia may also increase levels of free estrogens through decreasing concentrations of circulating sex hormone–binding globulin (32, 33). 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. 23), but results did not achieve statistical significance. Systemic unopposed estrogen therapy increases The risk was increased >6-fold among obese diabetic women compared with normal weight women without diabetes, whereas diabetics with low level of physical activity had ∼3-fold increased risk compared with women without diabetes and a high level of total physical activity. FOIA Beining RM, Dennis LK, Smith EM, Dokras A. Ann Epidemiol. 2006 Feb;35(1):159-66. doi: 10.1093/ije/dyi223. Endometrial cancers can be divided into two subtypes: type 1, which are estrogen dependent and comprise about 80% of all endometrial cancers, and type 2, which are non-estrogen dependent. 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. The observed associations persisted after finer adjustment for BMI to control for residual confounding. Cases (n = 723) were identified from a statewide tumor registry; controls (n = 2,291) were selected randomly from population lists. 2019 May 31;19(1):527. doi: 10.1186/s12885-019-5748-4. Furthermore, by linkage with the nationwide Swedish In-patient Registry, we identified women who had a hysterectomy for reasons other than endometrial cancer. We observed an ∼3-fold increased risk for obese women with diabetes comparing with obese women without diabetes. 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. The effect of diabetes on the risk of endometrial Cancer: an updated a systematic review and meta-analysis. 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. In an attempt to better disentangle the association of diabetes from the association of obesity and physical inactivity with the increased risk of endometrial cancer, we did analyses stratified by BMI and physical activity (Table 3 Endometrial cancer is at the same time a malignancy with good prognosis. Physical inactivity, obesity, and diabetes are associated with different degrees of hyperinsulinemia. 2008 Jun;18(6):492-9. doi: 10.1016/j.annepidem.2007.11.011. Diabetes and cancer: Epidemiological and biological links. 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. By linkage of the cohort with the Swedish Cancer Registry through July 1, 2003 and with the Regional Cancer Registry in the study area through June 30, 2005, we identified 225 adenocarcinoma endometrial cancer cases. type 2 diabetes and endometrial cancer, finding that the risk of endometrial cancer rises with greater levels of obesity [7, 8]. 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. Thus, the observed increased risk of endometrial cancer associated with diabetes may in part reflect confounding by these factors. Body mass index (BMI) and other measures of obesity have been associated positively with both diabetes and endometrial cancer. History of diabetes was associated with a twofold increased risk of endometrial cancer among hypertensive women, but no association was observed among nonhypertensive women. Among 777 endometrial cancer cases and 1550 controls from Italy and Switzerland, odds ratio was 1.7 (95% confidence interval: 1.2–2.5) for diabetes, and 5.1 for obese diabetic women as compared with non-obese non-diabetic ones. ). 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. Diabetes shows a supramultiplicative effect with body mass index, but not with physical activity or hypertension. Lucenteforte E, Bosetti C, Talamini R, et al. 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 eCollection 2020. 2020 Aug 25;11:568. doi: 10.3389/fendo.2020.00568. Incomplete identification of diabetic women in the cohort could lead to attenuation of our results. the risk of endometrial cancer [8]. Abnormal vaginal bleeding is the most common symptom, but a woman may also experience discharge, weight loss, abdominal or pelvic pain, dysuria, … Int J Cancer 1999; 81:539. Other characteristics did not differ substantially between diabetics and nondiabetics. 52). 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). Diabetes has been associated with increased risk of endometrial cancer in some epidemiological studies. 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). Association of diabetes with risk of endometrial cancer stratified by BMI and physical activity. Obesity and physical inactivity are two important risk factors for diabetes and also for endometrial cancer. It is … Diabetes was associated with increased risk of endometrial cancer (RR = 1.72, 95% CI 1.48–2.01). Epub 2005 Oct 28. Methods Included were 337 women in the Health Surveys in North-Trøndelag, Norway who were followed from EC diagnosis to death or end of follow-up, 30th June 2012. 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. Studies were excluded if they provided only an effect estimate with no means to calculate a CI or if the estimates were not adjusted for age. This makes it hard to find a clear link. We do not retain these email addresses. 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). Endometrial cancer is one of the most common cancers of the female reproductive system. Additional adjustment for potential confounders, such as use of postmenopausal hormones, oral contraceptive use, parity, age at menopause, education, smoking, and total energy intake, did not change the results substantially (RR, 1.96; 95% CI, 1.23-3.12). 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. The risk associated with type 2 diabetes appeared not to vary greatly with … Family history Endometrial cancer tends to run in some families. The Swedish Cancer Registry and the Regional Cancer Registry have been estimated to be ∼100% complete (30). Some of the signs and symptoms of Endometrial Cancer in Patient with type 1 and type 2 diabetes … Among 777 endometrial cancer cases and 1550 controls from Italy and Switzerland, odds ratio was 1.7 (95% confidence interval: 1.2-2.5) for diabetes, and 5.1 for obese diabetic women as compared with non-obese non-diabetic ones. Would you like email updates of new search results? Body mass index (BMI) and other measures of obesity have been associated positively with both diabetes and endometrial cancer. The OR of endometrial cancer in women with history of diabetes was 3.0 for women with a body mass index (BMI) (QI) kg/m 2 <25, 3.6 for those with a BMI of 25–29, and 3.3 for those with a BMI ≥30. It increases the risk of colorectal, breast , and bladder cancer by 20% to 50%. Diabetes was associated with increased risk of endometrial cancer (RR = 1.72, 95% CI 1.48-2.01). This study was approved by the Ethics Committees at the Uppsala University Hospital (Uppsala, Sweden) and the Karolinska Institutet (Stockholm, Sweden). 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. Weight history and risk of endometrial cancer among Chinese women. It is not clear whether or not the association of diabetes with endometrial cancer is explained entirely by obesity. Some people, especially those with prediabetes or type 2 diabetes, may not experience symptoms initially. 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. Fader AN, Arriba LN, Frasure HE, von Gruenigen VE. Privacy, Help Please enable it to take advantage of the complete set of features! Diabetes and cancer are common diseases with tremendous impact on health worldwide. Prevention and treatment information (HHS). The relative risk (RR) of endometrial cancer [with 95% confidence interval (95% CI)] was calculated by dividing the incidence rate among diabetic women with that among nondiabetic women. We examined the relationship of body mass index (BMI), diabetes and smoking to endometrial cancer risk in a cohort of 36 761 Norwegian women during … 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. The summary of RR in hospital-based studies was higher than other studies. 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. However, most of these studies used case-control study designs and did not adjust for obesity, an established risk factor for endometrial cancer. Another limitation is that it is difficult to clearly disentangle the association of diabetes from the association of obesity and physical inactivity with increased risk of endometrial cancer. Endometrial cancer may be about twice as common in women with type 2 diabetes. 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
