ABSTRACT

In 2018, cardiovascular disease (CVD) was the leading cause of death among women, and current CVD prevention paradigms may not be sufficient in this group. In that context, it has recently been proposed that detection of calcification in breast arteries may help improve CVD risk screening and assessment in apparently healthy women. This review provides an overview of breast arterial anatomy; and the epidemiology, pathophysiology, and measurement of breast artery calcium (BAC); and discusses the features of the BAC-CVD link. The potential clinical applications that BAC may offer for CVD prevention in the context of current clinical practice guidelines and recommendations are also discussed. Finally, current gaps in evidence gaps are outlined, and future directions in the field are explored with a focus on the implementation of BAC mammography as a CVD risk-screening tool in routine clinical practice.

ABSTRACT

Cardiovascular disease (CVD) and cancer continue to be the 2 leading causes of death in developed countries despite significant improvements in the prevention, screening, and treatment of both diseases. They remain significant public health problems, growing in importance globally. Despite this threat, the fields of cardiology and oncology have been relatively disconnected. With many shared modifiable risk factors, cancer and CVD often coexist in the same individuals; those diagnosed with lung cancer, breast cancer, and colon cancer are at higher risk of CVD, and those with CVD are at higher risk of developing many types of common cancers. Screening paradigms have been established in parallel, but there are opportunities for combined risk assessments for cancer and CVD risk. Joining forces for combined cardiovascular and hemato-oncological preventive and research efforts will likely have synergistic, worldwide public health benefits.

ABSTRACT

PURPOSE OF REVIEW: To discuss the classic analogy of "coronary artery calcium (CAC) as a mammogram of the heart", by evaluating the conceptual strengths, weaknesses, opportunities, and threats of a potential cardiovascular disease (CVD) screening strategy using CAC in apparently healthy adults. RECENT FINDINGS: CAC is typically used for further CVD risk assessment. CAC is also currently being used as a screening test in specific subgroups of individuals, particularly in some Asian countries. Although this has yielded valuable insights on the determinants and pathophysiology of CVD, whether this approach results in improved clinical outcomes compared to other assessment and management approaches is currently unclear. Although CAC and mammograms share a number of characteristics, there are also important conceptual differences. The evidence supporting CAC, which is a robust CVD risk assessment tool, for CVD screening purposes is currently very limited, and further research is needed.

ABSTRACT

Sipuleucel-T, an autologous cellular immunotherapy manufactured from antigen-presenting cells primed to recognize prostatic acid phosphatase, was the first immunotherapy product approved by the US FDA. It was approved for men with asymptomatic or minimally symptomatic metastatic castration-resistant prostate cancer after it was shown to provide a survival advantage. Additional studies have examined its use in other clinical settings and in combination with other approved and investigational immunotherapy agents. This review will discuss the pivotal trials leading to approval, will outline some of the biomarkers associated with its efficacy and will review some of the ongoing combination strategies. Maximizing the efficacy of sipuleucel-T through better patient selection or through combination approaches remains the challenge of the future.

ABSTRACT

OPINION STATEMENT: Prostate cancer is the most common non-cutaneous cancer diagnosed in men and the second leading cause of male cancer deaths in the USA. While most cases are diagnosed in early stages, some will present as or progress to metastatic disease and eventually castration-resistant prostate cancer (mCRPC) which has a mortality rate exceeding 50 %. There are currently six approved systemic life-prolonging therapies for use in mCRPC, yet little data to guide sequencing. Clinical factors, including the presence or absence of symptoms and the presence or absence of visceral metastases, should help determine the best therapeutic choice at each treatment node. Those with asymptomatic bone-only disease could be considered for sipuleucel-T, abiraterone, enzalutamide, or docetaxel in the first-line setting. For symptomatic disease, docetaxel could be used or radium-223 if disease is only present in the bone. In the second-line setting, sipuleucel-T or radium-223 can be used in the appropriate clinical setting. Taxane chemotherapy could be used if a novel androgen-directed therapy was used in the first-line setting. Cabazitaxel, if docetaxel was previously used, should be considered. There is scarce data on best treatment options in the third-line setting. In general, we recommend alternating between androgen-targeting agents and taxane chemotherapy. Finally, consideration should be given to testing for the androgen receptor splice variant AR-V7, which may be a relevant treatment-specific biomarker to aid in the selection of androgen-targeting therapy versus chemotherapy at each treatment juncture. Mutation testing for DNA damage repair defects can also be considered, as such patients may benefit from investigational poly ADP ribose polymerase (PARP) inhibitors or platinum-based chemotherapies. Several ongoing studies have been designed to answer some of these sequencing questions, including the biomarker questions, and will hopefully continue to inform us about rational therapy selection in mCRPC.

ABSTRACT

OBJECTIVES: This study sought to determine if coronary artery calcium (CAC) is associated with incident noncardiovascular disease. BACKGROUND: CAC is considered a measure of vascular aging, associated with increased risk of cardiovascular and all-cause mortality. The relationship with noncardiovascular disease is not well defined. METHODS: A total of 6,814 participants from 6 MESA (Multi-Ethnic Study of Atherosclerosis) field centers were followed for a median of 10.2 years. Modified Cox proportional hazards ratios accounting for the competing risk of fatal coronary heart disease were calculated for new diagnoses of cancer, pneumonia, chronic obstructive pulmonary disease (COPD), chronic kidney disease (CKD), deep vein thrombosis/pulmonary embolism, hip fracture, and dementia. Analyses were adjusted for age; sex; race; socioeconomic status; health insurance status; body mass index; physical activity; diet; tobacco use; number of medications used; systolic and diastolic blood pressure; total and high-density lipoprotein cholesterol; antihypertensive, aspirin, and cholesterol medication; and diabetes. The outcome was first incident noncardiovascular disease diagnosis. RESULTS: Compared with those with CAC = 0, those with CAC >400 had an increased hazard of cancer (hazard ratio [HR]: 1.53; 95% confidence interval [CI]: 1.18 to 1.99), CKD (HR: 1.70; 95% CI: 1.21 to 2.39), pneumonia (HR: 1.97; 95% CI: 1.37 to 2.82), COPD (HR: 2.71; 95% CI: 1.60 to 4.57), and hip fracture (HR: 4.29; 95% CI: 1.47 to 12.50). CAC >400 was not associated with dementia or deep vein thrombosis/pulmonary embolism. Those with CAC = 0 had decreased risk of cancer (HR: 0.76; 95% CI: 0.63 to 0.92), CKD (HR: 0.77; 95% CI: 0.60 to 0.98), COPD (HR: 0.61; 95% CI: 0.40 to 0.91), and hip fracture (HR: 0.31; 95% CI: 0.14 to 0.70) compared to those with CAC >0. CAC = 0 was not associated with less pneumonia, dementia, or deep vein thrombosis/pulmonary embolism. The results were attenuated, but remained significant, after removing participants developing interim nonfatal coronary heart disease. CONCLUSIONS: Participants with elevated CAC were at increased risk of cancer, CKD, COPD, and hip fractures. Those with CAC = 0 are less likely to develop common age-related comorbid conditions, and represent a unique population of "healthy agers."

ABSTRACT

We present the case of a 61-year-old female with an acute onset of polyarthritis involving the wrists, hands, knees, and ankles. Associated systemic symptoms included fever, weight loss, and lymphadenopathy. Serologic workup revealed positive rheumatoid factor (RF) and anti-cyclic citrullinated protein (anti-CCP) antibodies. Radiograph imaging of her bilateral hands and wrists showed erosive joint disease and lymph node, and bone marrow biopsy confirmed a diagnosis of T cell lymphoblastic leukemia. Our case demonstrates a unique clinical phenotype of paraneoplastic arthritis and is only the second reported case of RF, anti-CCP-positive arthritis related to a hematological malignancy. We review the only three published cases of seropositive paraneoplastic arthritis. In each case, systemic symptoms or a poor response to steroid treatment triggered additional workup. These cases highlight the importance of careful clinical assessment and vigilance to rule out secondary causes of inflammatory arthritis, even in patients with seropositive erosive arthritis.
