Older adults are vulnerable to chemotherapy toxicity; however, there limited data identify those at risk. The goals of this study risk factors for toxicity in older and develop a stratification schema toxicity.Patients age ≥ 65 years with cancer from seven institutions completed prechemotherapy assessment that captured sociodemographics, tumor/treatment variables, laboratory test results, geriatric variables (function, comorbidity, cognition, psychological state, social activity/support,...

Five years of adjuvant tamoxifen therapy for estrogen receptor (ER) -positive breast cancer is more effective than 2 use. However, information on discontinuation scanty. We sought to identify predictors among older women with cancer.Within six health care delivery systems, we identified >or= 65 old diagnosed stage I IIB ER-positive or indeterminant between 1990 and 1994 who had filled a prescription tamoxifen. observed them 5 after initial prescription. used automated pharmacy records...

BACKGROUND Frailty has been suggested as a construct for oncologists to consider in treating older cancer patients. Therefore, the authors assessed potential of creating deficit‐accumulation frailty index (DAFI) from largely self‐administered comprehensive geriatric assessment (CGA). METHODS Five hundred patients aged ≥65 years underwent CGA before receiving chemotherapy. A DAFI was constructed, resulting 51‐item scale, and cutoff values were examined robust/nonfrail (cutoff value, 0.0 <...

The NCCN Guidelines for Older Adult Oncology address specific issues related to the management of cancer in older adults, including screening and comprehensive geriatric assessment (CGA), assessing risks benefits treatment, preventing or decreasing complications from therapy, managing patients deemed be at high risk treatment-related toxicity. CGA is a multidisciplinary, in-depth evaluation that assesses objective health adult while evaluating multiple domains, which may affect prognosis...

Objective In older men with prostate cancer, aging is associated reduced anxiety and increased depression. The purpose of this study was to examine the association among age, anxiety, depression in a cohort adults receiving chemotherapy.

Multimorbidity is common among middle-aged and older adults; however the prospective effects of multimorbidity on health outcomes (health status, major decline, mortality) have not been fully explored. This study addresses this gap in literature.We used self-reported data from 2008 2010 Health Retirement Study. Our population included 13,232 adults aged 50 or older. measure baseline was based occurrence co-occurrence chronic conditions, functional limitations, and/or geriatric syndromes, as...

Abstract Chemotherapy treatment-related side-effects are common and increase the risk of suboptimal outcomes. Exercise interventions during cancer treatment improve self-reported physical functioning, fatigue, anxiety, depression, but it is unclear whether these important clinical outcomes, such as chemotherapy relative dose intensity (RDI). The National Cancer Institute funded Nutrition to Improve Treatment-Related Outcomes (ENICTO) Consortium, address this knowledge gap. This paper...

Background Nutritional status can directly affect morbidity and mortality in older adults with cancer. This study evaluated the association between pretreatment body mass index (BMI), albumin level, unintentional weight loss (UWL) prior 6 months chemotherapy toxicity among solid tumors. Methods was a secondary analysis of prospective, multicenter involving chemotherapy‐treated patients 65 years old or older. Geriatric assessment, BMI, UWL data were collected before treatment. Multivariable...
