Each year, the American Cancer Society estimates the numbers of new cancer cases and deaths expected in the United States in the current year and compiles the most recent data on cancer incidence, mortality, and survival based on incidence data from the National Cancer Institute, the Centers for Disease Control and Prevention, and the North American Association of Central Cancer Registries and mortality data from the National Center for Health Statistics. A total of 1,638,910 new cancer cases and 577,190 deaths from cancer are projected to occur in the United States in 2012. During the most recent 5 years for which there are data (2004‐2008), overall cancer incidence rates declined slightly in men (by 0.6% per year) and were stable in women, while cancer death rates decreased by 1.8% per year in men and by 1.6% per year in women. Over the past 10 years of available data (1999‐2008), cancer death rates have declined by more than 1% per year in men and women of every racial/ethnic group with the exception of American Indians/Alaska Natives, among whom rates have remained stable. The most rapid declines in death rates occurred among African American and Hispanic men (2.4% and 2.3% per year, respectively). Death rates continue to decline for all 4 major cancer sites (lung, colorectum, breast, and prostate), with lung cancer accounting for almost 40% of the total decline in men and breast cancer accounting for 34% of the total decline in women. The reduction in overall cancer death rates since 1990 in men and 1991 in women translates to the avoidance of about 1,024,400 deaths from cancer. Further progress can be accelerated by applying existing cancer control knowledge across all segments of the population, with an emphasis on those groups in the lowest socioeconomic bracket.

BACKGROUND Excess bodyweight, expressed as increased body-mass index (BMI), is associated with the risk of some common adult cancers. We did a systematic review and meta-analysis to assess the strength of associations between BMI and different sites of cancer and to investigate differences in these associations between sex and ethnic groups. METHODS We did electronic searches on Medline and Embase (1966 to November 2007), and searched reports to identify prospective studies of incident cases of 20 cancer types. We did random-effects meta-analyses and meta-regressions of study-specific incremental estimates to determine the risk of cancer associated with a 5 kg/m2 increase in BMI. FINDINGS We analysed 221 datasets (141 articles), including 282,137 incident cases. In men, a 5 kg/m2 increase in BMI was strongly associated with oesophageal adenocarcinoma (RR 1.52, p<0.0001) and with thyroid (1.33, p=0.02), colon (1.24, p<0.0001), and renal (1.24, p <0.0001) cancers. In women, we recorded strong associations between a 5 kg/m2 increase in BMI and endometrial (1.59, p<0.0001), gallbladder (1.59, p=0.04), oesophageal adenocarcinoma (1.51, p<0.0001), and renal (1.34, p<0.0001) cancers. We noted weaker positive associations (RR <1.20) between increased BMI and rectal cancer and malignant melanoma in men; postmenopausal breast, pancreatic, thyroid, and colon cancers in women; and leukaemia, multiple myeloma, and non-Hodgkin lymphoma in both sexes. Associations were stronger in men than in women for colon (p<0.0001) cancer. Associations were generally similar in studies from North America, Europe and Australia, and the Asia-Pacific region, but we recorded stronger associations in Asia-Pacific populations between increased BMI and premenopausal (p=0.009) and postmenopausal (p=0.06) breast cancers. INTERPRETATION Increased BMI is associated with increased risk of common and less common malignancies. For some cancer types, associations differ between sexes and populations of different ethnic origins. These epidemiological observations should inform the exploration of biological mechanisms that link obesity with cancer.

BackgroundErectile dysfunction (ED) is highly prevalent among men with type 2 diabetes mellitus (T2DM) and reflects systemic vascular and metabolic dysfunction. Shared mechanisms include endothelial dysfunction, oxidative stress, inflammation, autonomic neuropathy, and hypogonadism. Therefore, ED may function not only as a complication of T2DM but also as an early clinical marker of cardiometabolic disease.ObjectiveThis narrative review summarizes current evidence on the epidemiology, mechanisms, and cardiometabolic implications of ED in men with T2DM, and evaluates the impact of major cardiometabolic therapies on erectile function. A real-world cohort study was conducted using the TriNetX Global Collaborative Network, a large federated electronic health record database comprising healthcare organizations across multiple countries.ContentED is closely linked with hypertension, obesity, dyslipidaemia, heart failure, ischemic heart disease, and stroke in men with T2DM, reflecting shared microvascular and macrovascular diseases. Cohort and real-world studies indicate a strong bidirectional relationship: poor cardiometabolic control worsens erectile function, whereas improvements in glycaemia, weight, blood pressure, and lipids are associated with higher International Index of Erectile Function (IIEF) scores. Using data from the TriNetX Global Collaborative Network, large-scale real-world analyses further demonstrate that the coexistence of ED and T2DM substantially increases cardiovascular risk. In a propensity-score-matched cohort (&gt;200,000 individuals per group), men with ED and T2DM had higher risks of ischemic heart disease (15.7% vs. 11.5%, OR: 1.44; 95% CI 1.41-1.46), stroke (OR 1.45; 95% CI 1.42-1.48), peripheral artery disease (OR 1.38; 95% CI 1.35-1.41), and heart failure (8.4% vs. 4.9%, OR 1.78; 95% CI 1.74-1.81). Conversely, among individuals with T2DM, the presence of ED was associated with increased ischemic heart disease, stroke, and peripheral artery disease. Mechanistic and clinical data suggest heterogeneous treatment effects: GLP-1 receptor agonists and SGLT2 inhibitors show promising vascular benefits with mixed erectile outcomes, whereas ARBs and finerenone appear favorable compared with older agents associated with sexual adverse effects.ConclusionED in T2DM should be regarded as a clinically relevant marker of systemic vascular disease. Routine assessment may enhance cardiovascular risk stratification and motivate earlier, comprehensive risk-factor intervention. Future prospective and randomized studies with erectile function as a predefined endpoint are needed.

Background Intracoronary provocation testing with acetylcholine (ACh) is helpful to diagnose and risk‐stratify patients with ischemia with nonobstructed coronary arteries (NOCA) and myocardial infarction with NOCA. This study explored potential sex‐related disparities on the prognostic significance of ACh provocative testing. Methods Consecutive patients with ischemia with NOCA and those with myocardial infarction with NOCA who underwent ACh provocation testing were enrolled. The primary end point was the incidence of major adverse cardiovascular and cerebrovascular events at follow‐up. Co‐primary end points were angina recurrence and quality of life assessed by 12‐month Seattle Angina Questionnaire (SAQ) summary score. Results A total of 519 patients (mean age, 61.4±12.1 years; 275 [53.0%] women and 244 [47%] men) were enrolled: 346 (66.7%) with ischemia with NOCA and 173 (33.3%) with myocardial infarction with NOCA. A positive ACh test was observed in 274 (52.8%) patients, with a lower prevalence of epicardial spasm (82 [56.2%] versus 106 [82.8%]) and a higher prevalence of microvascular spasm (64 [43.8%] versus 22 [17.2%]) in women compared with men (P>0.001). After a median 22‐month follow‐up, major adverse cardiovascular and cerebrovascular events occurred in 53 (10.2%) patients, without significant sex differences (P>0.05). Men with a positive ACh test had a significantly higher rate of major adverse cardiovascular and cerebrovascular events (22 [17.2%] versus 5 [4.3%], P=0.002) compared with those with a negative test; no difference was observed in women (P>0.05) (P for interaction=0.003). Women with a positive test experienced a higher rate of angina recurrence (61 [41.8%] versus 32 [24.8%], P=0.005) and a lower SAQ summary score (82 [interquartile range, 72–90] versus 86 [interquartile range, 78–100], P<0.001) compared with those with a negative result; no difference was observed in men (P>0.05). Conclusions This study revealed the importance of recognizing sex‐specific differences in the prognostic value of ACh testing for proper management of coronary vasomotor disorders.
