Associations between nutritional factors and chemotherapy toxicity in older adults with solid tumors.

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, and unintentional weight loss (UWL) in the prior 6 months and chemotherapy toxicity among older adults with solid tumors. METHODS: This was a secondary analysis of a prospective, multicenter study involving chemotherapy-treated patients 65 years old or older. Geriatric assessment, BMI, albumin level, and UWL data were collected before treatment. Multivariable logistic regression models evaluated the associations between nutritional factors and the risk of grade 3 or higher (grade 3+) chemotherapy toxicity. RESULTS: Seven hundred fifty patients with a median age of 72 years (range, 65-94 years) and mostly stage IV disease were enrolled. The median pretreatment BMI and albumin values were 26 kg/m2 (range, 15.1-52.1 kg/m2 ) and 3.9 mg/dL (range, 1.0-5.0 mg/dL), respectively. Nearly 50% of the patients reported UWL, with 17.6% reporting >10% UWL. Multivariable analysis revealed no association between >10% UWL and a risk for grade 3+ chemotherapy toxicity (adjusted odds ratio [AOR], 0.87; P = .58). Multivariable analysis showed a trend toward an association between a BMI ≥ 30 kg/m2 and a decreased risk of grade 3+ chemotherapy toxicity (AOR, 0.65; P = .06), whereas a low albumin level (≤3.6 mg/dL) was associated with a higher risk of grade 3+ chemotherapy toxicity (AOR, 1.50; P = .03). An analysis of the joint effect of BMI and albumin demonstrated the lowest risk of grade 3+ chemotherapy toxicity among patients with high BMIs (≥30 kg/m2 ) and normal albumin levels (AOR, 0.41; P = .008). CONCLUSIONS: Among older adults with solid tumors, higher BMIs and normal albumin levels are associated with a lower risk of grade 3+ chemotherapy toxicity. Additional research is warranted to define the clinical significance of nutritional markers and to inform future interventions.

Randomized Trial of Standard Adjuvant Chemotherapy Regimens Versus Capecitabine in Older Women With Early Breast Cancer: 10-Year Update of the CALGB 49907 Trial.

PURPOSE: Older women with breast cancer remain under-represented in clinical trials. The Cancer and Leukemia Group B 49907 trial focused on women age 65 years and older. We previously reported the primary analysis after a median follow-up of 2.4 years. Standard adjuvant chemotherapy showed significant improvements in recurrence-free survival (RFS) and overall survival compared with capecitabine. We now update results at a median follow-up of 11.4 years. PATIENTS AND METHODS: Patients age 65 years or older with early breast cancer were randomly assigned to either standard adjuvant chemotherapy (physician's choice of either cyclophosphamide, methotrexate, and fluorouracil or cyclophosphamide and doxorubicin) or capecitabine. An adaptive Bayesian design was used to determine sample size and test noninferiority of capecitabine. The primary end point was RFS. RESULTS: The design stopped accrual with 633 patients at its first sample size assessment. RFS remains significantly longer for patients treated with standard chemotherapy. At 10 years, in patients treated with standard chemotherapy versus capecitabine, the RFS rates were 56% and 50%, respectively (hazard ratio [HR], 0.80; P = .03); breast cancer-specific survival rates were 88% and 82%, respectively (HR, 0.62; P = .03); and overall survival rates were 62% and 56%, respectively (HR, 0.84; P = .16). With longer follow-up, standard chemotherapy remains superior to capecitabine among hormone receptor-negative patients (HR, 0.66; P = .02), but not among hormone receptor-positive patients (HR, 0.89; P = .43). Overall, 43.9% of patients have died (13.1% from breast cancer, 16.4% from causes other than breast cancer, and 14.1% from unknown causes). Second nonbreast cancers occurred in 14.1% of patients. CONCLUSION: With longer follow-up, RFS remains superior for standard adjuvant chemotherapy versus capecitabine, especially in patients with hormone receptor-negative disease. Competing risks in this older population dilute overall survival benefits.

Subcortical brain iron deposition and cognitive performance in older women with breast cancer receiving adjuvant chemotherapy: A pilot MRI study.

As the number of older adults in the U.S. increases, so too will the incidence of cancer and cancer-related cognitive impairment (CRCI). However, the exact underlying biological mechanism for CRCI is not yet well understood. We utilized susceptibility-weighted imaging with quantitative susceptibility mapping, a non-invasive MRI-based technique, to assess longitudinal iron deposition in subcortical gray matter structures and evaluate its association with cognitive performance in women age 60+ with breast cancer receiving adjuvant chemotherapy and age-matched women without breast cancer as controls. Brain MRI scans and neurocognitive scores from the NIH Toolbox for Cognition were obtained before chemotherapy (time point 1) and within one month after the last infusion of chemotherapy for the patients and at matched intervals for the controls (time point 2). There were 14 patients age 60+ with breast cancer (mean age 66.3 ±â€¯5.3 years) and 13 controls (mean age 68.2 ±â€¯6.1 years) included in this study. Brain iron increased as age increased. There were no significant between- or within- group differences in neurocognitive scores or iron deposition at time point 1 or between time points 1 and 2 (p > 0.01). However, there was a negative correlation between iron in the globus pallidus and the fluid cognition composite scores in the control group at time point 1 (r = -0.71; p < 0.01), but not in the chemotherapy group. Baseline iron in the putamen was negatively associated with changes in the oral reading recognition scores in the control group (r = 0.74, p < 0.01), but not in the chemotherapy group. Brain iron assessment did not indicate cancer or chemotherapy related short-term differences, yet some associations with cognition were observed. Studies with larger samples and longer follow-up intervals are warranted.

An Analysis of the Inclusion of Medications Considered Potentially Inappropriate in Older Adults in Chemotherapy Templates for Hematologic Malignancies: One Recommendation for All?

BACKGROUND: There remains a paucity of data regarding the use of potentially inappropriate medications (PIMs) in the supportive management of older adults undergoing chemotherapy. Raising awareness among healthcare providers regarding the frequency of their use and potential toxicities may help to minimize the risks to patients. OBJECTIVE: The aim of this study was to evaluate the frequency of six specific classes of medications considered PIMs by the American Geriatrics Society Beers Criteria that are commonly included in the National Comprehensive Cancer Network (NCCN) chemotherapy order templates for hematologic malignancies. The six PIMs evaluated are first-generation antihistamines, benzodiazepines, corticosteroids, H2-receptor antagonists, metoclopramide, and antipsychotics. METHODS: A total of 311 unique chemotherapy order templates published online by the NCCN for the treatment of hematologic malignancies were reviewed to determine the frequency that these six specific PIMs were recommended for supportive care. RESULTS: Approximately 45% of the NCCN chemotherapy templates for hematologic malignancies specifically recommended the use of at least one of the six PIMs examined. The remainder of the templates evaluated referred exclusively to the NCCN Guidelines® on Oncology for Antiemesis, which also included the use of at least one of the six PIMs evaluated. CONCLUSIONS: These findings demonstrate that PIMs are frequently used as supportive therapy in the treatment of hematologic malignancies. Increasing healthcare provider awareness of their potential side effects may minimize the risks associated with their use in older adults with hematologic malignancies undergoing chemotherapy.

Lymphedema, musculoskeletal events and arm function in older patients receiving adjuvant chemotherapy for breast cancer (Alliance A171302).

PURPOSE: Musculoskeletal events (MEs) resulting from breast cancer treatment can significantly interfere with the quality of life (QOL) of older adults. We evaluated the incidence of MEs in women 65 years and older who had surgery and adjuvant chemotherapy for breast cancer, and the impact of treatment on MEs and arm function. PATIENTS AND METHODS: Patient-reported data in Alliance/CALGB 49907 were collected using the EORTC QLQ-BR23 and physician-reported adverse events to characterize self-reported MEs and incidence of lymphedema. EORTC QLQ-BR23 items related to musculoskeletal events were analyzed in this study and data collected at study entry (post-operative) and 12 and 24 months post-entry. RESULTS: Lymphedema, arm function, and ME data were available for 321 patients. One or more MEs were reported by 87% (median number = 3) and 64% (median number = 1) of patients post-operatively and at 24 months. At 24 months 2% had persistence of six MEs. Seventy-four percent experienced at least ≥3/6 types of MEs over the 24-month period. Detection of lymphedema at any time during the study was noted in 7.5% of the patients and appeared to be associated with the type of chemotherapy given: CMF 16.4%, capecitabine 5.8%, and AC 4%. Mastectomy and axillary node dissection were associated with the most MEs. LROM correlated with poorer arm function at all time periods. CONCLUSION: Potentially debilitating MEs occur in three-fourths of elderly women undergoing standard therapy for breast cancer. Emphasis should be placed on prevention, identification, and treatment of these MEs to improve QOL.

Global geriatric oncology: Achievements and challenges.

The aging of the population is a global challenge. The number of older adults is rapidly growing, leading to an increase in the prevalence of noncommunicable diseases associated with aging, such as cancer. Worldwide, older adults account for approximately half of all cancer cases, and this proportion is projected to increase globally. Furthermore, the majority of older adults live in less developed regions, where health systems are generally ill-equipped to provide care for complex chronic conditions. Worldwide, there is paucity of geriatric training, and most of the oncology workforce lacks the skills and knowledge to provide comprehensive care for older patients. Various initiatives aimed at providing adequate clinical care for older adults, increasing the geriatric skills and knowledge of healthcare professionals, and developing geriatric oncology research, have been successfully implemented. However, most developments in geriatric oncology have taken place in high-income countries, and there are still large inequalities in the availability of clinical, educational, and research initiatives across different regions of the world. This article provides an overview of geriatric oncology initiatives in Asia, Europe, Australia and New Zealand, Latin America, and the United States and Canada. Understanding the achievements and challenges of geriatric oncology around the world, and fostering international collaboration in research and training are essential for improving the care of all older adults with cancer.

Improving Nurses' Knowledge About Older Adults With Cancer.

PURPOSE/OBJECTIVES: To assess nurses' knowledge, attitudes, and perceptions of caring for older adults and to use that assessment data to develop a training program to improve skills in caring for older adults with cancer. 
. DESIGN: Survey of oncology nursing staff conducted pre- and posteducation regarding geriatric care.
. SETTING: City of Hope, a comprehensive cancer center in southern California.
. SAMPLE: 422 (baseline) and 375 (postintervention) nursing staff in adult care areas. 
. METHODS: The primary endpoint was the difference between baseline and postintervention knowledge. Secondary endpoints included differences in attitudes and perceptions of caring for older adults in an oncology setting. A two-sample t test was performed to compare the mean results between baseline and follow-up surveys.
. MAIN RESEARCH VARIABLES: Knowledge, attitudes, and perceptions of caring for older adults.
. FINDINGS: Survey comparisons from baseline to postintervention demonstrated statistically significant increases in nurses' knowledge of geriatric care after the implementation of an educational program targeted at oncology nurses. Nurses' attitudes remained the same pre- versus posteducation. A significant change reflecting a better perception was noted in the burden of behavioral problems; however, a worsening was noted in disagreements among staff; disagreements involving staff, patients, and families; and limited access to geriatric services. Both surveys highlighted the need to provide more education for staff about geriatric care issues and to make available more geriatric-specific resources. 
. CONCLUSIONS: Knowledge about caring for older adults is needed for oncology nurses, and a geriatric education program for oncology nurses can result in improved knowledge in a variety of domains. Surveying staff highlighted the positive attitude of nurses toward caring for older adults at the study institution. The use of this survey identified key issues facing older adults and ways to improve care.
. IMPLICATIONS FOR NURSING: Additional knowledge about caring for older adults for oncology nurses and assistive staff is needed to prepare for the increasing population of older adults with cancer. Continuous learning is key to professional development, and more research is needed on how to best continue to integrate knowledge of geriatric concepts into oncology care.

How do I best manage insomnia and other sleep disorders in older adults with cancer?

Insomnia is common in older adults with cancer, with a reported prevalence of 19-60% in prior studies. Cancer treatments are associated with increased risk of insomnia or aggravation of pre-existing insomnia symptoms, and patients who are receiving active cancer treatments are more likely to report insomnia. Insomnia can lead to significant physical and psychological consequences with increased mortality. We discuss physiological sleep changes in older adults, and illustrated the various sleep disorders. We present a literature review on the prevalence and the effects of insomnia on the quality of life in older adults with cancer. We discuss the risk factors and presented a theoretical framework of insomnia in older adults with cancer. We present a case study to illustrate the assessment and management of insomnia in older adults with cancer, comparing and contrasting a number of tools for sleep assessment. There are currently no guidelines on the treatment of sleep disorders in older adults with cancer. We present an algorithm developed at the City of Hope Comprehensive Cancer Center by a multidisciplinary team for managing insomnia, using evidence-based pharmacologic and non-pharmacologic interventions.

Effect of Pretreatment Renal Function on Treatment and Clinical Outcomes in the Adjuvant Treatment of Older Women With Breast Cancer: Alliance A171201, an Ancillary Study of CALGB/CTSU 49907.

PURPOSE: CALGB 49907 showed the superiority of standard therapy, which included either cyclophosphamide/doxorubicin (AC) or cyclophosphamide/methotrexate/fluorouracil over single-agent capecitabine in the treatment of patients age ≥ 65 with early-stage breast cancer. The treatment allowed dosing adjustments of methotrexate and capecitabine for pretreatment renal function. The purpose of the current analysis was to assess the relationship between pretreatment renal function and five end points: toxicity, dose modification, therapy completion, relapse-free survival, and overall survival. METHODS: Pretreatment renal function was defined as creatinine clearance (CrCl) using the Cockcroft-Gault equation. Multivariable logistic and proportional hazards regression were used to model separately for each regimen the relationship between CrCl and the first three binary end points and the last two time-to-event end points, respectively, after adjusting for variables of prognostic importance. RESULTS: Six hundred nineteen assessable patients were analyzed. The incidence of stage III (moderate) or stage IV (severe) renal dysfunction was 72%, 64%, and 75% for treatment with cyclophosphamide/methotrexate/fluorouracil, AC, and capecitabine, respectively. There was no relationship for any regimen between pretreatment renal function and the five end points. For AC, as CrCl increased, the odds of nonhematologic toxicity decreased (P = .008), whereas for capecitabine, as CrCl increased, the odds of experiencing toxicity of any type also increased (P = .035). Patients with renal insufficiency who received dose modifications were not at increased risk for complications compared with those who did not have renal insufficiency and received a full dose. CONCLUSION: Excluding from clinical trials patients with renal insufficiency but good performance status on the basis of concern of excessive hematologic toxicity or poor outcomes may not be justified with appropriate dosing modifications. Results should be considered in the design of clinical trials for older patients.

Interdisciplinary Palliative Care for Patients With Lung Cancer.

CONTEXT: Palliative care, including symptom management and attention to quality of life (QOL) concerns, should be addressed throughout the trajectory of a serious illness such as lung cancer. OBJECTIVES: This study tested the effectiveness of an interdisciplinary palliative care intervention for patients with Stage I-IV non-small cell lung cancer (NSCLC). METHODS: Patients undergoing treatments for NSCLC were enrolled in a prospective, quasi-experimental study whereby the usual care group was accrued first followed by the intervention group. Patients in the intervention group were presented at interdisciplinary care meetings, and appropriate supportive care referrals were made. They also received four educational sessions. In both groups, QOL, symptoms, and psychological distress were assessed at baseline and 12 weeks using surveys which included the Functional Assessment of Cancer Therapy-Lung and the Lung Cancer Subscale, the 12-item Functional Assessment of Chronic Illness Therapy-Spiritual Well-Being, and the Distress Thermometer. RESULTS: A total of 491 patients were included in the primary analysis. Patients who received the intervention had significantly better scores for QOL (109.1 vs. 101.4; P < 0.001), symptoms (25.8 vs. 23.9; P < 0.001) spiritual well-being (38.1 vs. 36.2; P = 0.001), and lower psychological distress (2.2 vs. 3.3; P < 0.001) at 12 weeks, after controlling for baseline scores, compared to patients in the usual care group. Patients in the intervention group also had significantly higher numbers of completed advance care directives (44% vs. 9%; P < 0.001), and overall supportive care referrals (61% vs. 28%; P < 0.001). The benefits were seen primarily in the earlier stage patients vs. those with Stage IV disease. CONCLUSION: Interdisciplinary palliative care in the ambulatory care setting resulted in significant improvements in QOL, symptoms, and distress for NSCLC patients.

Impact of care at comprehensive cancer centers on outcome: Results from a population-based study.

BACKGROUND: Rigorous processes ensure quality of research and clinical care at National Cancer Institute-designated comprehensive cancer centers (NCICCCs). Unmeasurable elements of structure and process of cancer care delivery warrant evaluation. To the authors' knowledge, the impact of NCICCC care on survival and access to NCICCCs for vulnerable subpopulations remain unstudied. METHODS: The current study's population-based cohort of 69,579 patients had newly diagnosed adult-onset (aged 22-65 years) cancers reported to the Los Angeles County cancer registry between 1998 and 2008. Geographic information systems were used for geospatial analysis. RESULTS: With regard to overall survival across multiple diagnoses, patients not receiving their first planned treatment at NCICCCs experienced poorer outcomes compared with those treated at NCICCCs; differences persisted on multivariable analyses after adjusting for clinical and sociodemographic factors (hepatobiliary: hazard ratio [HR], 1.5; 95% confidence interval [95% CI], 1.4-1.7 [P<.001]; lung: HR, 1.4; 95% CI, 1.3-1.6 [P<.001]; pancreatic: HR, 1.5; 95% CI, 1.3-1.7 [P<.001]; gastric: HR, 1.3; 95% CI, 1.1-1.7 [P = .01]; breast: HR, 1.3; 95% CI, 1.1-1.5 [P<.001]; and colorectal: HR, 1.2; 95% CI, 1.0-1.4 [P = .05]). With regard to barriers to care, multivariable analyses revealed that a lower likelihood of treatment at NCICCCs was associated with race/ethnicity (African-American: OR range across diagnoses: 0.4-0.7 [P<.03]; Hispanic: OR range, 0.5-0.7 [P<.04]); lack of private insurance (public: OR range, 0.6-0.8 [P<.004]; uninsured: OR range, 0.1-0.5 [P<.04]); less than high socioeconomic status (high-middle: OR range, 0.4-0.7 [P<.02]; middle: OR range, 0.3-0.5 [P<.001]; and low: OR range, 0.2-0.6 [P<.01]), and residing >9 miles from the nearest NCICCC (OR range, 0.5-0.7 [P<.02]). CONCLUSIONS: Among individuals aged 22 to 65 years residing in Los Angeles County with newly diagnosed adult-onset cancer, those who were treated at NCICCCs experienced superior survival compared with those treated at non-NCICCC facilities. Barriers to care at NCICCCs included race/ethnicity, insurance, socioeconomic status, and distance to an NCICCC.

Socioeconomic and clinical factors are key to uncovering disparity in accrual onto therapeutic trials for breast cancer.

To monitor and address disparity in accrual, patient participation in cancer clinical trials is routinely summarized by race/ethnicity. To investigate whether confounding obscures racial/ethnic disparity in participation, all women with breast cancer treated by medical oncologists at City of Hope Comprehensive Cancer Center from 2004 through 2009 were classified by birthplace and self-reported race/ethnicity, and followed for accrual onto therapeutic trials through 2010. Undetectable on univariate analysis, significantly reduced participation by subjects of African, Asian, Eastern European, Latin American, and Middle Eastern ancestries was revealed after accounting for age, socioeconomic factors, tumor and oncologist characteristics, and intrapractice clustering of patients.

Comorbidity, chemotherapy toxicity, and outcomes among older women receiving adjuvant chemotherapy for breast cancer on a clinical trial: CALGB 49907 and CALGB 361004 (alliance).

PURPOSE: We evaluated associations among comorbidity, toxicity, time to relapse (TTR), and overall survival (OS) in older women with early-stage breast cancer receiving adjuvant chemotherapy. METHODS: Cancer and Leukemia Group B 49907 (Alliance) randomly assigned women ≥ 65 years old with stages I-III breast cancer to standard adjuvant chemotherapy or capecitabine. We reviewed data from 329 women who participated in the quality of life companion study CALGB 70103 and completed the Physical Health Subscale of the Older American Resources and Services Questionnaire. This questionnaire captures data on 14 comorbid conditions and the degree to which each interferes with daily activities. A comorbidity burden score was computed by multiplying the total number of conditions by each condition's level of interference with function. Outcomes were grade 3 to 5 toxicity, TTR, and OS. Logistic regression was used to evaluate associations between comorbidity and toxicity, and Cox proportional hazards models for TTR and survival. RESULTS: Number of comorbidities ranged from 0 to 10 (median 2); the comorbidity burden score ranged from 0 to 25 (median 3). The most common conditions were arthritis (58%) and hypertension (55%). Comorbidity was associated with shorter OS, but not with toxicity or TTR. The hazard of death increased by 18% for each comorbidity (hazard ratio [HR] = 1.18, 95% CI = 1.06 to 1.33) after adjusting for age, tumor size, treatment, node and receptor status. Comorbidity burden score was similarly associated with OS (HR = 1.08; 95% CI, 1.03 to 1.14). CONCLUSIONS: Among older women enrolled onto a clinical trial, comorbidity was associated with shorter OS, but not toxicity or relapse.

Phase I/II trial of vinorelbine and sorafenib in metastatic breast cancer.

PURPOSE: We investigated the efficacy and toxicity of sorafenib, a multikinase inhibitor of vascular endothelial growth factor receptor tyrosine kinase, in combination with vinorelbine therapy in a phase I/II trial in patients with metastatic breast cancer. PATIENTS AND METHODS: We enrolled 11 patients in the phase I portion to determine the maximum tolerated dose (MTD) of the combination, followed by 35 extra patients treated at the MTD in phase II. The median age of patients was 54 years old (range, 31-72 years old). Tumors were estrogen receptor and progesterone receptor (ER/PR) positive in 54% (22/54) of patients, and triple negative (ER(-), PR(-), HER2(-)) in 41% (17/54) of patients. Of all patients, 22% received sorafenib and vinorelbine as first-line therapy, 37% as second-line therapy, and 41% as third-line therapy. RESULTS: In total, 41 patients were treated at the MTD (6 during phase I; 35 in phase II). The observed 44% 4-month progression-free survival rate was similar to the estimated historical rate of 43% with vinorelbine treatment. The combination was tolerated with expected toxicities. Patients treated at the MTD who had received prior bevacizumab treatment received a median of 1.5 cycles (range, 1-10 cycles) compared with a median of 5 cycles (range, 2-12 cycles) for patients without prior bevacizumab treatment. CONCLUSION: Further evaluation of vinorelbine and sorafenib in bevacizumab-naive patients may be of interest if specific biomarkers guiding patient selection can be identified.

Barriers to treatment in patients with locally advanced breast cancer.

Delays between presentation and treatment could have a significant effect on breast cancer mortality. The authors hypothesized that patient, physician, and system barriers are all responsible for treatment delays. Therefore, a study was conducted to define prevalent barriers to treatment from the patient's perspective. A modified 43-item Likert-scale questionnaire was administered to patients with clinical stage III locally advanced breast cancer (LABC) who had experienced a delay in treatment of 3 months or more. Between October 2008 and January 2010, 153 patients presented with LABC; 43 patients (28.1%) met eligibility, and 40 completed the questionnaire. Among the patient barriers reported, 38% of patients delayed care for fear of losing their breast and 47% awaited previously scheduled routine appointments instead of seeking care. Among the physician barriers reported, 20% of physicians of initial contact did not believe the breast lump/symptom was related to cancer and 15% did not believe it needed a biopsy. Among the system barriers reported, the most prevalent were delays in performing diagnostic tests and obtaining insurance authorization for tests, treatment, or physician visits. Substantial delays were seen in 28.1% of patients from presentation to when they sought therapy at City of Hope Comprehensive Cancer Center. The high prevalence of patient barriers versus physician/system barriers suggests that increased educational efforts for patients and health care professionals are needed.

Cognitive function in older women with breast cancer treated with standard chemotherapy and capecitabine on Cancer and Leukemia Group B 49907.

Cognitive changes in older women receiving chemotherapy are poorly understood. We examined self-reported cognitive function for older women who received adjuvant chemotherapy on Cancer and Leukemia Group B (CALGB) 49907. CALGB 49907 randomized 633 women aged ≥65 with stage I-III breast cancer to standard adjuvant chemotherapy (cyclophosphamide-methotrexate-5-fluorouracil or doxorubicin-cyclophosphamide) versus capecitabine. We examined self-reported cognitive function in 297 women (CALGB 361002) who enrolled on the quality of life substudy and had no gross impairment on cognitive screening. Women were evaluated using an 18-item instrument at six time points (baseline through 24 months). At each time point for each patient, we calculated a cognitive function score (CFS) defined as the mean response of items 1-18 and defined impairment as a score >1.5 standard deviations above the overall average baseline score. Differences in scores by patient characteristics were evaluated using a Kruskal-Wallis test. A linear mixed-effects model was used to assess CFSs by treatment over time. Among 297 women, the median age was 71.5 (range 65-85) and 73 % had performance status of 0. Baseline depression and fatigue were reported in 6 and 14 % of patients, respectively. The average CFS at baseline was 2.08 (corresponding to "normal ability"), and baseline cognitive function did not differ by treatment regimen (p = 0.350). Over 24 months, women reported minimal changes at each time point and insignificant differences by treatment arm were observed. In a healthy group of older women, chemotherapy was not associated with longitudinal changes in self-reported cognitive function.

Impact of a bilingual education intervention on the quality of life of Latina breast cancer survivors.

PURPOSE/OBJECTIVES: To test the effectiveness of a bilingual education intervention to improve the quality of life (QOL) of Latina breast cancer survivors (BCSs) after completing primary treatment for breast cancer. DESIGN: A two-group prospective, longitudinal, randomized, controlled trial. SETTING: An ambulatory-care setting of a designated comprehensive cancer center in southern California. SAMPLE: 52 English- and Spanish-speaking Latina BCSs. METHODS: Women were randomly assigned to the experimental or attention control group and completed measures of QOL, uncertainty, distress, and acculturation at baseline, and at three and six months postintervention. MAIN RESEARCH VARIABLES: QOL, uncertainty, and distress. FINDINGS: After controlling for acculturation, the four dimensions of QOL increased slightly in the groups or remained unchanged without significant group-by-time interaction. The social and psychological well-being subscales had the lowest scores, followed by physical and spiritual well-being. Although the group-by-time interaction was not statistically significant, the post-hoc difference for total QOL between time 2 and time 3 in the experimental group approached significance, with a slight increase in total QOL. CONCLUSIONS: Latina BCSs have multiple survivorship and QOL concerns that might put them at risk for poor QOL. IMPLICATIONS FOR NURSING: More culturally congruent intervention studies are needed to address the paucity of intervention research with Latina BCS. KNOWLEDGE TRANSLATION: Core values must be incorporated in the development of health education programs. Those programs also should be linguistically appropriate and available to non-English-speaking Latinas. In this way, the informational and supportive needs of all BCSs can be met.

Integrating a cancer-specific geriatric assessment into survivorship care.

Older adults constitute the greatest percentage of cancer survivors in the country, with 61% being aged 65 years and older. Assessing older adult cancer survivors beyond chronological age to include changes in functional status is an essential process to help nurses anticipate cancer treatment impact and aid in planning individualized survivorship care. The objective of this article is to identify a method to assess older adult cancer survivors to be used in tailoring survivorship care. A review of geriatric literature was conducted through MEDLINE(®) and PubMed from 1997-2011 and focused on the pathophysiology of aging, cancer impact, and comorbidities in this population. Results were combined with previous research to provide an evidence-based approach to assessing older cancer survivors. The resulting assessment provides valuable information on the functional status of older adult patients with cancer. This assessment can be used by nurses to develop treatment plans and tailor management strategies to improve quality of life.

Use of complementary medications among older adults with cancer.

BACKGROUND: Little is known about complementary medication use among older adults with cancer, particularly those who are receiving chemotherapy. The objective of this study was to evaluate the prevalence of complementary medication use and to identify the factors associated with its use among older adults with cancer. METHODS: The prevalence of complementary medication use (defined as herbal agents, minerals, or other dietary supplements, excluding vitamins) was evaluated in a cohort of adults aged ≥65 years who were about to start chemotherapy for their cancer. The associations between complementary medication use and patient characteristics (sociodemographics; comorbidities; and functional, nutritional, psychological, and cognitive status), medication use (number of medications and concurrent vitamin use), and cancer characteristics (type and stage) were analyzed. RESULTS: The cohort included 545 patients (mean age, 73 years; range, 65-91 years; 52% women) with cancer (61% stage IV). Seventeen percent of these patients (N = 93) reported using ≥1 complementary medication; the mean number of complementary medications among users was 2 (range, 1-10 medications). Complementary medication use was associated with 1) earlier cancer stage (29% had stage I-II disease vs 17% with stage III-IV disease; odds ratio [OR], 2.05; 95% confidence interval [CI], 1.21-3.49) and 2) less impairment with instrumental activities of daily living (OR, 1.39; 95% CI, 1.12-1.73). CONCLUSIONS: Complementary medication use was reported by 17% of older adults with cancer and was more common among those who had less advanced disease (i.e., those receiving adjuvant, potentially curative treatment) and higher functional status. Further studies are needed to determine the association between complementary medication use and cancer outcomes among older adults.

Effect of creatinine clearance on patterns of toxicity in older patients receiving adjuvant chemotherapy for breast cancer.

OBJECTIVE: A number of age-related physiological changes contribute to an increased risk of toxicity of cancer chemotherapy in the elderly. One of the most important of these changes is the progressive decline in renal function with aging. We sought to determine the association between calculated creatinine clearance (CL(CR)) and grade 3 or 4 toxicities during adjuvant chemotherapy in women > or =65 years of age with breast cancer. DESIGN AND METHODS: We identified 1405 patients > or =65 years of age who had been treated for primary invasive breast cancer at Memorial Sloan-Kettering Cancer Center between January 1998 and December 2000. Patients were included in this analysis if they had stage I-III breast cancer and had received adjuvant chemotherapy. Patients were excluded if they had a prior history of breast cancer or chemotherapy, or had no baseline creatinine value available for review. RESULTS: The 126 patients who met our criteria had received either cyclophosphamide, methotrexate and fluorouracil (CMF) [n = 65, mean age 71, range 65-78] or an anthracycline-based regimen (n = 61, mean age 69, range 65-79). The majority of patients (97%) had a normal creatinine. CL(CR), as calculated by the Cockcroft-Gault and Jeliffe formulas, decreased with increasing age (increased age associated with decreased Cockcroft-Gault [p = 0.02]; increased age associated with decreased Jeliffe [p < 0.01]). In multivariate analysis, after controlling for age and co-morbidity, a CL(CR) <50 mL/min by the Cockcroft-Gault formula was associated with an increased risk of fever and neutropenia (odds ratio [OR] 3.60; 95% CI 1.00, 12.94; p = 0.05) and a CL(CR) <50 mL/min by the Jeliffe formula was associated with a trend towards an increased risk of fever and neutropenia (OR 3.30; 95% CI 0.91, 12.33; p = 0.07), grade 3 or 4 haematological toxicity (OR 2.43; 95% CI 0.90, 6.55; p = 0.08), and need for erythropoietin (OR 4.15; 95% CI 0.81, 2.99; p = 0.09). An increase in creatinine (as a continuous variable) was associated with a trend towards an increased risk of grade 3 or 4 haematological toxicity (OR 5.81; 95% CI 0.96, 35.33; p = 0.06). CONCLUSIONS: In this cohort of older breast cancer patients, a decreased CL(CR) and increased creatinine was associated with an increased risk of fever and neutropenia or haematological toxicity. CL(CR) should be considered when determining chemotherapy dosage in the elderly.
