Nutritional impairment, psychological health and quality of life among older adults with advanced cancer: A secondary analysis of a randomized clinical trial.

BACKGROUND: Nutritional impairment is associated with treatment toxicity and worse overall survival in patients with cancer. We aimed to (1) evaluate the association of nutritional impairment with psychological health and quality of life (QOL) and (2) examine which measures of nutrition had the strongest association with psychological health and QOL among older adults receiving cancer treatment with palliative intent. METHODS: This secondary analysis was performed on baseline data from a nationwide cluster randomized clinical trial (ClinicalTrials.gov identifier: NCT02107443; PI: Mohile). Adults age ≥70 with advanced cancer and ≥1 geriatric assessment (GA) impairment were enrolled from 2014 to 2017. In line with geriatric oncology standards, we defined nutritional impairment as Mini Nutritional Assessment Short Form (MNA-SF) ≤11, body mass index (BMI) <21 kg/m2, or >10% involuntary weight loss in the past 6 months. We conducted multivariable linear regressions to evaluate the association of nutritional impairment with each measure of psychological health and QOL: Geriatric Depression Scale (GDS-15, range 0-15), Generalized Anxiety Disorder-7 (GAD-7, range 0-21), NCCN Distress Thermometer (NCCN DT, range 0-10), and Functional Assessment of Cancer Therapy-General (FACT-G, range 0-108). Analyses were adjusted for patient demographics, clinical characteristics, and GA. RESULTS: Among 541 patients, the mean age was 77 (range 70-96) and 60% had nutritional impairment. Mean baseline scores: GDS-15 3.1 (SD 2.7), GAD-7 2.9 (SD 4.0), NCCN DT 2.9 (SD 2.7), and FACT-G 80 (SD 15). In the adjusted model, compared to those with no nutritional impairment, older adults with nutritional impairment had greater depression (ß = 0.79, 95% CI 0.36-1.23) and anxiety severity (ß = 0.86, 95% CI 0.19-1.53), and worse QOL (ß = -6.31, 95% CI -8.62 to -4.00). Of the measures of nutrition, MNA-SF ≤11 demonstrated the strongest associations with depression, anxiety, distress, and QOL. CONCLUSION: Nutritional impairment is associated with impaired psychological health and worse QOL. Clinicians should use the MNA-SF to screen older adults for nutritional impairment and offer tailored supportive interventions.

Behavioral, psychological, and supportive care interventions in geriatric oncology: The Cancer and Aging Research Group infrastructure core.

Current research efforts focusing on improving outcomes of older adults with cancer lack the appropriate infrastructure to support this growing need. The Cancer and Aging Group R21/33 National Institute of Health (NIH)/National Institute of Aging (NIA) grant aims to support development of geriatric oncology research through dedicated cores. The mission of the Core on Behavioral, Psychological, and Supportive Care Interventions will be to provide guidance in the field of non-pharmacological interventions. The Core will provide investigators with expertise, advocacy, and support in study design, development, and execution.

Relationships of self-perceived age with geriatric assessment domains in older adults with cancer.

OBJECTIVES: Older self-perceived age is associated with poor health and higher healthcare utilization in the geriatric population. We evaluated the associations of self-perceived age with geriatric assessment (GA) domain impairments in older adults with cancer. METHODS: This was a secondary analysis of baseline data from a GA cluster-randomized trial (URCC 13070; PI: Mohile). We included patients aged ≥70 with incurable stage III/IV solid tumor or lymphoma considering or receiving treatment and had ≥1 GA domain impairment other than polypharmacy. Multivariate analyses were used to evaluate the associations of age difference between chronological and self-perceived age (categorized into "feeling younger than chronological age" vs. "feeling the same or older than their chronological age") with GA domain impairments. RESULTS: We included 533 patients; mean age was 76.6 (SD 5.2). On multivariate analyses, compared to those who felt younger than their chronological age, those who felt the same or older were more likely to have impairments in physical performance [Adjusted Odds Ratio (AOR) 5.42, 95% Confidence Interval (CI) 1.69-17.40)], functional status (AOR 2.31, 95% CI 1.73-3.07), comorbidity (AOR 1.62, 95% CI 1.20-2.19), psychological health (AOR 2.62, 95% CI 1.85-3.73), and nutrition (AOR 1.65, 95% CI 1.20-2.28). They were also more likely to screen positively for polypharmacy (AOR 1.86, 95% CI 1.30-2.65). CONCLUSIONS: Older adults with cancer who felt the same or older than their chronological age were more likely to have GA domain impairments. Further studies are needed to better understand the relationships between self-perceived age, aging-related conditions, and outcomes in this population.

Comorbidity in older adults with cancer.

Comorbidity is an issue of growing importance due to changing demographics and the increasing number of adults over the age of 65 with cancer. The best approach to the clinical management and decision-making in older adults with comorbid conditions remains unclear. In May 2015, the Cancer and Aging Research Group, in collaboration with the National Cancer Institute and the National Institute on Aging, met to discuss the design and implementation of intervention studies in older adults with cancer. A presentation and discussion on comorbidity measurement, interventions, and future research was included. In this article, we discuss the relevance of comorbidities in cancer, examine the commonly used tools to measure comorbidity, and discuss the future direction of comorbidity research. Incorporating standardized comorbidity measurement, relaxing clinical trial eligibility criteria, and utilizing novel trial designs are critical to developing a larger and more generalizable evidence base to guide the management of these patients. Creating or adapting comorbidity management strategies for use in older adults with cancer is necessary to define optimal care for this growing population.

Geriatric assessment with management in cancer care: Current evidence and potential mechanisms for future research.

Older adults with cancer represent a complex patient population. Geriatric assessment (GA) is recommended to evaluate the medical and supportive care needs of this group. "GA with management" is a term encompassing the resultant medical decisions and interventions implemented in response to vulnerabilities identified on GA. In older, non-cancer patients, GA with management has been shown to improve a variety of outcomes, such as reducing functional decline and health care utilization. However, the role of GA with management in the older adult with cancer is less well established. Rigorous clinical trials of GA with management are necessary to develop an evidence base and support its use in the routine oncology care of older adults. At the recent U-13 conference, "Design and Implementation of Intervention Studies to Improve or Maintain Quality of Survivorship in Older and/or Frail Adults with Cancer," a session was dedicated to developing research priorities in GA with management. Here we summarize identified knowledge gaps in GA with management studies for older patients with cancer and propose areas for future research.
