Objectives To characterize the individual and combined effects of multimorbidity and functional limitation on healthcare use and mortality in a large, community cohort of individuals with heart failure (HF). Design Prospective cohort study. Setting Eleven southeastern Minnesota counties. Participants Individuals (mean age 74, 54% male) with a first‐ever HF code ( International Classification of Diseases, Ninth Revision code 428 or Tenth Revision code I50) between January 1, 2013 and March 31, 2016 (N=2,692). Measurements Eight activities of daily living measured using a survey on a Likert scale (1=without any difficulty, 5=unable to do; median=8). Participants with a score greater than 8 were categorized as having functional limitation. Multimorbidity was defined as having 2 or more noncardiac comorbidities. Results Twenty‐five percent of participants had neither multimorbidity nor functional limitation, 35% had multimorbidity, 9% had functional limitation, and 31% had both. After adjustment, participants with multimorbidity and functional limitation had greater risks of all outcomes (death: hazard ratio (HR)=4.92, 95% confidence interval (CI)=3.03–8.00; emergency department (ED) visit: HR=3.67, 95% CI=2.94–4.59; hospitalization: HR=3.66, 95% CI=2.85–4.70; outpatient visit: HR=1.73, 95% CI=1.52–1.96) than those with neither. Participants with functional limitation alone had greater risks of death (HR=4.84, 95% CI=2.78–8.43), ED visits (HR=2.35, 95% CI=1.75–3.16), and hospitalizations (HR=2.10, 95% CI=1.52–2.88) but not outpatient visits. Those with multimorbidity alone had similar risks of ED visits and hospitalizations as those with functional limitation alone but were more likely to have outpatient visits (HR=1.50, 95% CI=1.34–1.67). Conclusion Individuals with both multimorbidity and functional limitation have the highest risk of death and healthcare use. Individuals with only functional limitation have similar rates of hospitalizations and ED visits as those with only multimorbidity, underscoring the need to consider both when managing individuals with HF.

Objective: Predictors of long-term functional impairment in acute respiratory failure of all causes are poorly understood. Our objective was to assess the frequency and predictors of long-term functional impairment or death after invasive mechanical ventilation for acute respiratory failure of all causes. Design: Population-based, observational cohort study. Setting: Eight adult ICUs of a single center. Patients: All adult patients from Olmsted County, Minnesota, without baseline functional impairment who received mechanical ventilation in ICUs for acute respiratory failure of all causes from 2005 through 2009. Interventions: None. Measurements and Main Results: In total, 743 patients without baseline functional impairment received mechanical ventilation in the ICU. At 1- and 5-year follow-up, the rates of survival with return to baseline functional ability were 61% (366/597) and 53% (356/669). Among 71 patients with new functional impairment at 1 year, 55% (39/71) had recovered and were alive without functional impairment at 5 years. Factors predictive of new functional impairment or death at 1 year were age, comorbidities, discharge to other than home, mechanical ventilation of 7 days or longer, and stroke. Of factors known at the time of intubation, the following are predictive of new functional impairment or death: age, comorbidities, nonsurgical condition, Acute Physiology and Chronic Health Evaluation III score, stroke, and sepsis. Post hoc sensitivity analyses revealed no significant change in predictor variables in patient populations when stroke was excluded or who received more than 48 hours of mechanical ventilation. Conclusions: At 1- and 5-year follow-up, many patients who received mechanical ventilation for acute respiratory failure from all causes are no longer alive or have new moderate-to-severe functional impairment. Functional recovery between year 1 and year 5 is possible and common. Sepsis, stroke, illness severity, age, and comorbidities predict long-term functional outcome at intubation.

114 Background: We evaluated baseline differences in arm tissue composition (fat mass, lean mass, bone mineral content [BMC] and bone mineral density [BMD]) between the affected and unaffected arms in women with breast cancer-related lymphedema (BRCL). We compared changes in arm tissue composition and self-reported lymphedema symptoms after one-year of weight-lifting vs. usual-care. Methods: We utilized data from the PAL trial that included 141 women with BRCL. Arm tissue composition was quantified using dual-energy x-ray absorptiometry. The severity of lymphedema was quantified using self-report survey. Weight-lifting was performed at community fitness facilities. Results: At baseline, the affected arm had more fat (D= 89.7±21.0g; P < 0.001) and lean mass (D= 149.1±25.3g; P < 0.001), but less BMC (D= -3.2±0.9g; P < 0.001) than the unaffected arm. No difference was observed in BMD. After 12-months of weight-lifting, composition of the affected arm was improved: lean mass (71.2±27.9g; P = 0.01) and BMD (0.01±0.01g; P = 0.02) increased, arm fat percentage decreased (0.01±0.01; P = 0.003). No changes observed in fat mass and BMC. Baseline body mass index and BCRL grade modified the relationship between weight-lifting and tissue composition changes. Increases in lean mass were associated with less severe BCRL symptoms. With every one-percent decrease in arm fat percentage, affected limb volume reduced 13.81mL. Conclusions: Among women with BRCL, affected and unaffected arms differ in tissue composition. These differences may be improved with weight-lifting. Changes in arm tissue composition correlate with improved BCRL symptoms. Investigating the combined effects of exercise and weight-loss on arm tissue composition and BCRL symptoms may provide additional insight to the benefits of lifestyle modification on lymphedema biology.

253 Background: cPMP is chronic pain in the front thorax, axilla, and/or upper half of the arm beginning after mastectomy or lumpectomy persisting > 3 months after treatment and presents with pain, allodynia and disability. cPMP occurs in half of all patients with breast cancer and is severe in 13% (Gartner R JAMA 2009). Epidural bupivacaine, memantine, gabapentin or venlafaxine may help prevent cPMP, but there are no established proven treatments. (Shen J, Up to Date 2016) Scrambler therapy (ST) is an FDA-cleared treatment for neuropathic pain supported by multiple trials in over 800 patients with cancer pain, chemotherapy induced neuropathic pain, back pain, and post herpetic neuropathy (PHN). (Majithia N JSSC 2016) Methods: We treated 2 women with cPMP with standard ST, with repeated treatment if the pain returned. ST was done with ECG pads above and below the pain for 45 minutes daily, until pain resolved, and repeated if/when pain recurred. Results: Case 1: A 60 year-old woman had bilateral mastectomy 2 years prior with cPMP like “a barbed wire bra”. Before treatment, her pain was 8, which decreased to 0-2 after 5 treatments. Her pain returned 4 months later and was successfully retreated. She resumed a more normal life and was able to taper and eventually stop her opioids. Case 2: A 56 year-old woman had deep aching cPMP for a year following chemo, Mastectomy, and RT. Her pain was 10, decreased to 0-1/10. Her pain returned 1 month later; 3 treatments reduced her pain from 4/10 to 0/10 and improved her quality of life, which lasted for several months until cancer recurrence. Conclusions: Scrambler therapy successfully treated cPMP in 2 patients with improved pain and quality of life, and enabled one patient to stop her opioids in line with new CDC guidelines. Scrambler therapy appears to hold promise, as it does in chemotherapy-induced neuropathy, failed back syndrome, PHN, low back pain and other conditions; prospective trials are indicated to further evaluate this treatment modality.

54 Background: After diagnosis and treatment, lung cancer survivors do not return to a health-related quality of life (QOL) and function comparable to pre-diagnosis levels as observed in other adult cancer survivors. We hypothesize that inadequate attention has been paid to addressing and improving QOL and function among lung cancer survivors. Our primary goal is to evaluate existing symptoms and QOL deficits among lung cancer survivors. Methods: We are evaluating patterns of QOL deficits (scored 5 or less on the scale from 0 [worst] to 10 [best]) in relation to time of lung cancer diagnosis, treatments, progression and/or recurrence, and health-related conditions. We are collecting and analyzing relevant health care utilization for selected QOL deficits, and identifying availability, accessibility, and effectiveness of evidence-based interventions. The expected outcomes will be new knowledge on patterns of QOL deficits, quality-adjusted life years in relation to the availability, accessibility, and adequacy of needed care and the effectiveness of interventions targeting improvement in QOL and symptoms. Results: In our initial analysis, among 3,707 lung cancer survivors who were diagnosed in 1999 to 2010, post-cancer treatment, and followed through 2011, 39% (1,442) reported deficits in overall QOL, 71% fatigue, 60% dyspnea, 41% being sedentary, 17% low spiritual well-being (SWB), and 10% currently smoking cigarettes. Among the 1,442 lung cancer survivors with a deficit in overall QOL, 97.5% reported severe fatigue or dyspnea, being sedentary or smoking, or having low SWB. In the remaining 36 of the 1,442, 24 had pain, cough, poor appetite, or other symptoms; only 12 (<1%) did not report deficit in any of the measured QOL domains. Analyses are ongoing. Conclusions: Based on evidence gained to date, we are developing and testing interventions targeting symptoms and QOL deficits. We expect to gain strong evidence for recommendations in redefining and delivering care and support that are necessary for improving the health and QOL of lung cancer survivors.

Purpose To provide evidence-based guidance on the optimum management of chronic pain in adult cancer survivors. Methods An ASCO-convened expert panel conducted a systematic literature search of studies investigating chronic pain management in cancer survivors. Outcomes of interest included symptom relief, pain intensity, quality of life, functional outcomes, adverse events, misuse or diversion, and risk assessment or mitigation. Results A total of 63 studies met eligibility criteria and compose the evidentiary basis for the recommendations. Studies tended to be heterogeneous in terms of quality, size, and populations. Primary outcomes also varied across the studies, and in most cases, were not directly comparable because of different outcomes, measurements, and instruments used at different time points. Because of a paucity of high-quality evidence, many recommendations are based on expert consensus. Recommendations Clinicians should screen for pain at each encounter. Recurrent disease, second malignancy, or late-onset treatment effects in any patient who reports new-onset pain should be evaluated, treated, and monitored. Clinicians should determine the need for other health professionals to provide comprehensive pain management care in patients with complex needs. Systemic nonopioid analgesics and adjuvant analgesics may be prescribed to relieve chronic pain and/or to improve function. Clinicians may prescribe a trial of opioids in carefully selected patients with cancer who do not respond to more conservative management and who continue to experience distress or functional impairment. Risks of adverse effects of opioids should be assessed. Clinicians should clearly understand terminology such as tolerance, dependence, abuse, and addiction as it relates to the use of opioids and should incorporate universal precautions to minimize abuse, addiction, and adverse consequences.

Introduction. High BMI is a risk factor for upper body breast cancer-related lymphedema (BCRL) onset. Black cancer survivors are more likely to have high BMI than White cancer survivors. While observational analyses suggest up to 2.2 times increased risk of BCRL onset for Black breast cancer survivors, no studies have explored race or other social factors that may affect BCRL severity, operationalized by interlimb volume difference (ILD).Materials and Methods. ILD was measured by perometry for 296 overweight (25 > BMI < 50) Black (n=102) or White (n=194) breast cancer survivors (>6 months from treatment) in the WISER Survivor trial. Multivariable linear regression examined associations between social and physical factors and ILD.Results. Neither Black race (−0.26,p=0.89) nor BMI (0.22,p=0.10) was associated with ILD. Attending college (−4.89,p=0.03) was the strongest factor associated with ILD, followed by having more lymph nodes removed (4.75,p=0.01), >25% BCRL care adherence (4.10,p=0.01), and years since treatment (0.55,p<0.001).Discussion. Neither race nor BMI was associated with ILD among overweight cancer survivors. Education, a proxy for resource level, was the strongest factor associated with greater ILD. Tailoring physical activity and weight loss interventions designed to address BCRL severity by resource rather than race should be considered.
