Current Breast Cancer Reports最新文献

Purpose of review: Breast cancer screening is highly controversial and different agencies have widely varying guidelines. Yet it is currently used extensively in the USA and frequently the thought is "the more, the better." The purpose of this review is to objectively assess the risks and benefits of screening mammography and consider whether there may be areas where it could be de-escalated.

Recent findings: Over the past few years, there have been several meta-analyses that are concordant, and it is now agreed that the main benefit of screening mammography is about a 20% reduction in breast cancer mortality. This actually benefits about 5% of patients with mammographically detected tumors. We now appreciate that the main harm of screening is overdiagnosis, i.e. detection of a cancer that will not cause the patient any harm and would not have ever been detected without the screening. This currently represents about 20 to 30% of screening detected cancers. Finding extra cancers with more intense screening is not always good, because in this situation, the risk of overdiagnosis increases and the benefit decreases. In some groups, the risk of overdiagnosis approaches 75%.

Summary: Our goal should be not only to find more cancers, but to avoid finding cancers that would never have caused the patient any harm and lead to unnecessary treatment. The authors suggest some situations where it may be reasonable to de-escalate screening.

Purpose of review: The COVID-19 pandemic has placed unprecedented challenges on breast cancer patients and health care providers. The impact of the pandemic on preexisting breast cancer disparities remains unknown but is projected to have adverse outcomes.

Recent findings: Early work has demonstrated that pandemic-related temporary suspensions in breast cancer screening, interruption of clinical trials, and treatment delays have an adverse impact on breast cancer patient outcomes and may worsen disparities.

Summary: In this review, we highlight existing knowledge regarding breast cancer disparities and the impact of the COVID-19 pandemic. Strategies for mitigating disparities moving forward include targeted research evaluating race-specific outcomes, targeted education for providers regarding breast health disparities, improved access to telehealth, maintenance of patient navigation programs, and patient education regarding the safety and necessity of enrollment in clinical trials.

Purpose of review: Obese breast cancer patients have poorer outcomes compared to non-obese patients. The intent of this review is to discuss recent studies and analyses regarding the status of the obesity epidemic and its effect on breast cancer incidence and outcomes. Subsequently, we will introduce a program implemented at a New York City hospital to reduce the morbidity and mortality of breast cancer patients with obesity.

Recent findings: The prevalence of obesity among adult Americans is 42%, spanning all racial and socioeconomic groups. Importantly, obesity is associated with multiple chronic diseases including cancer. Among breast cancer patients, obesity is linked to higher mortality and poorer clinical outcomes, including but not limited to distant recurrence and secondary malignancies.

Summary: Current treatment of breast cancer patients does not address the link between obesity and poorer prognosis. Here, we present a general strategy for reducing the morbidity and mortality of obese breast cancer patients by addressing the obesity epidemic.
