The immune system is characterized by the generation of structurally and functionally heterogeneous immune cells that constitute complex innate and adaptive immunity. This heterogeneity of immune cells results from changes in the expression of genes without altering DNA sequence. To achieve this heterogeneity, immune cells orchestrate the expression and functional status of transcription factor (TF) networks, which can be broadly categorized into 3 classes: pioneer TFs that facilitate initial commitment and differentiation of hematopoietic cells, subset-specific TFs that promote the generation of selected cell lineages, and immune-signaling TFs that regulate specialized function in differentiated cells...

Most, if not all, human cancers exhibit altered epigenetic signatures that promote aberrant gene expression that contributes to cellular transformation. Historically, attempts to pharmacologically intervene in this process have focused on DNA methylation and histone acetylation. More recently, genome-wide studies have identified histone and chromatin regulators as one of the most frequently dysregulated functional classes in a wide range of cancer types. These findings have provided numerous potential therapeutic targets including many that affect histone methylation...

Chromatin packaging of DNA provides a framework for transcriptional regulation. Modifications to DNA and histone proteins in nucleosomes lead to conformational changes, alterations in the recruitment of transcriptional complexes, and ultimately modulation of gene expression. We provide a focused review of control mechanisms that help modulate the activation and deactivation of gene transcription specifically through histone acetylation writers and readers in cancer. The chemistry of these modifications is subject to clinically actionable targeting, including state-of-the-art strategies to inhibit basic oncogenic mechanisms related to histone acetylation...

DNA methyltransferase inhibitors, so-called hypomethylating agents (HMAs), are the only drugs approved for the treatment of higher-risk myelodysplastic syndromes and are widely used in this context. However, it is still unclear why some patients respond to HMAs, whereas others do not. Recent sequencing efforts have identified molecular disease entities that may be specifically sensitive to these drugs, and many attempts are being made to clarify how HMAs affect the malignant clone during treatment. Here, we review the most recent data on the clinical effects of HMAs in myeloid malignancies...

Targeting DNA hypermethylation, using nucleoside analogs, is an efficient approach to reprogram cancer cell epigenome leading to reduced proliferation, increased differentiation, recognition by the immune system, and ultimately cancer cell death. DNA methyltransferase inhibitors have been approved for the treatment of myelodysplastic syndromes, chronic myelomonocytic leukemia, and acute myelogenous leukemia. To improve clinical efficacy and overcome mechanisms of drug resistance, a second generation of DNA methyltransferase inhibitors has been designed and is currently in clinical trials...

Epigenetic alterations such as DNA methylation defects and aberrant covalent histone modifications occur within all cancers and are selected for throughout the natural history of tumor formation, with changes being detectable in early onset, progression, and ultimately recurrence and metastasis. The ascertainment and use of these marks to identify at-risk patient populations, refine diagnostic criteria, and provide prognostic and predictive factors to guide treatment decisions are of growing clinical relevance...

Next year will mark 60 years since Dr. Leslie Foulds outlined his hypothesis that cancer is "a dynamic process advancing through stages that are qualitatively different," leading the way to our view of cancer progression as we know it today. Our understanding of the mechanisms of these stages has been continuously evolving this past half-century, and there has always been an active discussion of the roles of both genetic and epigenetic changes in directing this progression. In this review, we focus on the roles one particular epigenetic mark-DNA methylation-plays in these various "discontinuous" stages of cancer...

There are relatively limited data on outcomes of screening older adults for cancer; therefore, the decision to screen older adults requires balancing the potential harms of screening and follow-up diagnostic tests with the possibility of benefit. Harms of screening can be amplified in older and frail adults and include discomfort from undergoing the test itself, anxiety, potential complications from diagnostic procedures resulting from a false-positive test, false reassurance from a false-negative test, and overdiagnosis of tumors that are of no threat and may result in overtreatment...

Managing cancer pain in older adults can be complex and challenging. Understanding the unique needs of older patients with cancer is important to safe and effective pain management. The goals of this review are to discuss the assessment of older adults with cancer-related pain, treatment of cancer pain, and adverse effects or potential risks from treatment that are unique to older patients. A detailed pain assessment and when possible utilizing the geriatric assessment are vital to developing a cancer pain management plan...

The diagnosis of prostate cancer in elderly men is likely to increase over the next several decades, owing to changing demographics and a rising population of men older than 65 years. Given the heterogeneity and well-documented challenges in screening, diagnosing, and managing indolent versus aggressive prostate cancer, the geriatric patient population is particularly vulnerable to prostate cancer treatment nuances. Clinicians must become familiar with geriatric assessment tools to better answer life-expectancy questions prior to counseling patients on treatment options...

The management of early-stage breast cancer in older patients is complex and requires a careful balance of the risk of cancer death with the competing risks of comorbidities and treatment-related toxicity in women with largely favorable disease. As the US population continues to age, oncologists will increasingly encounter this clinical challenge. Several strategies involving each core component of breast cancer therapy have been investigated to minimize treatment in these patients while still maintaining acceptable outcomes...

There is increasing awareness of the special needs for care of the elderly cancer patient. Newer precise conformal radiotherapy techniques allow the safe delivery of higher doses of radiotherapy to the target tumor while reducing the dose to surrounding critical organs. This has led to a shortening of radiotherapy protocols for both curative and palliative indications. We review these novel techniques and protocols and the published clinical studies that include elderly patients treated with these techniques...

Advancing age remains one of the most significant risk factors for cancer development. Changes in the immune system occur with aging, and likely play a role in the increased incidence of malignancy in older patients. With the advent of immune checkpoint inhibitors, and their use in a variety of malignancies, there has been an explosion of clinical trials evaluating their use. Unfortunately, these trials have not shown consistent results in elderly patients, nor have age-specific outcomes been consistently reported...

Polypharmacy is prevalent in older adults with cancer and may be advantageous for the management of certain chronic disease states, but uncertainty exists regarding potential hazards and consequences. Cancer-related therapy adds to the prevalence of polypharmacy, which can lead to compromised cancer management plans (i.e., postoperative complications, treatment delays, and/or premature treatment discontinuation). Polypharmacy has been identified as one of the domains commonly included in the Comprehensive Geriatric Assessment likely because of the potential influence on health outcomes...

Cancer is a disease of older adults, and the majority of new cancer cases and deaths occur in people 65 years or older. However, fewer data are available regarding the risks and benefits of cancer treatment in older adults, and commonly used assessments in oncology fail to adequately evaluate factors that affect treatment efficacy and outcomes in the older patients. The geriatric assessment is a multidisciplinary evaluation that provides detailed information about a patient's functional status, comorbidities, psychological state, social support, nutritional status, and cognitive function...

The majority of patients with common malignancies are older adults. Intrinsic complex biological changes of aging along with inflammation, immunosenescence, age-associated chronic diseases, and extrinsic environmental and psychosocial factors have significant impact on not only development and behavior of individual malignancies, but also physiologic reserve and vulnerability of older patients who suffer from them. As a result, clinical practice of geriatric oncology demands integration of careful geriatric assessment and management...

The Affordable Care Act (ACA) requires health plans that provide coverage for dependents to cover adult children to age 26 years. Extensive evidence has shown that since its implementation in September 2010 insurance coverage and access to care for young adults in the general population have increased. This article reviews the studies that have evaluated the impacts of the ACA on access to cancer care and outcomes for young adults aged 19 to 25 years. Current literature shows that the ACA increased insurance rate and cancer diagnosis at early stage for young adults...

The Affordable Care Act (ACA) expanded access to high-quality end-of-life care for Americans with serious illness, including cancer. Before the ACA was enacted in 2010, nearly 715,000 patients died in hospitals annually, despite evidence that most Americans prefer to die at home. Moreover, fewer than half of Medicare beneficiaries used hospice before death, despite evidence that hospice services improve cancer patients' quality of life near death and caregivers' bereavement outcomes. The ACA-stipulated programs and subsequent efforts were designed to address these deficiencies in access to high-quality end-of-life care...
