Economic Hardship and Associated Factors of Women With Early-Stage Breast Cancer Prior to Chemotherapy Initiation.

INTRODUCTION: Economic hardship (EH) can negatively influence cancer outcomes. Little is known about the factors that are associated with higher levels of EH among patients with breast cancer (BC). This paper describes EH in women with early-stage BC prior to or at their first chemotherapy treatment (baseline) and explores whether there are differences by race, area deprivation, stress, symptom distress, and social support. PATIENTS AND METHODS: A descriptive comparative/correlational design was employed using baseline data of a multisite, longitudinal, multimethod study comparing the symptom experience and management prior to prescribed chemotherapy for women with early-stage BC. Participants completed measures for EH, perceived stress, symptom distress, and social support. Race was measured by self-report. Area deprivation indices (ADI) measuring neighborhood economic factors were calculated from publicly available websites. RESULTS: Participants (N = 248; age = 52.9 ± 12.3 years) were 62% White and 38% Black, 54% partnered, and 98% insured. Compared to White patients, Black patients reported higher (worse) EH (1.2 ± 3.0 vs. -0.7 ± 2.4), lived in areas of greater deprivation (80.1 ± 2.1 vs. 50.5 ± 23.5),and were more likely to report inadequate household income (Black: 30.5%; White: 11.1%). Adjusting for race and age, being Black (P< .001), living in an area of greater deprivation (P = .049), higher perceived stress (P = .008), lower perceived appraisal (P = .040), and less tangible support (P < .001) contributed to greater EH. Worse symptom distress trended toward greater EH (P = .07). CONCLUSIONS: This study emphasizes the importance of incorporating baseline holistic assessment to identify patients most likely to experience EH during early-stage BC treatment.

Factors influencing prostate cancer treatment decisions for African American and white men.

BACKGROUND: Prostate cancer racial disparities in mortality outcomes are the largest in all of oncology, and less aggressive treatment received by African American (AA) patients versus white patients is likely a contributing factor. However, the reasons underlying the differences in treatment are unclear. METHODS: This study examined a prospective, population-based cohort of 1170 men with newly diagnosed nonmetastatic prostate cancer enrolled from 2011 to 2013 before treatment throughout North Carolina. By phone survey, each participant was asked to rate the aggressiveness of his cancer, and his response was compared to the actual diagnosis based on a medical record review. Participants were also asked to rate the importance of 10 factors for their treatment decision-making process. RESULTS: Among AA and white patients with low-risk cancer (according to National Comprehensive Cancer Network guidelines), 78% to 80% perceived their cancers to be "not very aggressive." However, among high-risk patients, 54% of AA patients considered their cancers to be "not very aggressive," whereas 24% of white patients did (P < .001). Although both AA and white patients indicated that a cure was a very important decision-making factor, AAs were significantly more likely to consider cost, treatment time, and recovery time as very important. In a multivariable analysis, perceived cancer aggressiveness and cure as the most important factor were significantly associated with receiving any aggressive treatment and were associated with surgery (vs radiation). After adjustments for these factors and sociodemographic factors, race was not significantly associated with the treatment received. CONCLUSIONS: Racial differences in perceived cancer aggressiveness and factors important in treatment decision making provide novel insights into reasons for the known racial disparities in prostate cancer as well as potential targets for interventions to reduce these disparities.

Patient-reported outcomes in cancer survivorship.

BACKGROUND: There are currently 33 million cancer survivors worldwide. With improvements in early cancer detection and treatments, patients are living longer - and it is well-recognized that many survivors develop short- and long-term physical, psychosocial and spiritual effects as a result of their diagnoses and treatments. There is increasing awareness of the importance of using patient-reported outcomes (PROs) to accurately assess these effects in cancer survivors. Validated patient-reported outcome instruments: Traditionally, physicians have assessed the acute and late side effects of cancer treatments with standardized scales such as the CTCAE. However, multiple studies have demonstrated that PROs more accurately capture patient symptoms than physician assessment. In this article we describe frequently used, validated, general and cancer-specific PRO instruments that assess symptoms. We describe additional PRO instruments that assess unmet needs, interpersonal relationship issues, and psychosocial and financial problems. Published studies using these instruments have identified issues commonly faced by cancer survivors worldwide. Discussion and summary: While PROs are increasingly used in research, further efforts are needed to integrate PRO assessment into routine clinical care, so that timely and accurate assessments can translate into better management of issues - ultimately improving the lives of cancer survivors.

Prevalence of sarcopenia in older patients with colorectal cancer.

OBJECTIVE: Sarcopenia is the age-related loss of muscle mass, strength, and function. It is a common finding in older patients and is associated with decreased life expectancy and potentially higher susceptibility to chemotherapy toxicity. This study describes the prevalence of sarcopenia in older adults with early stage colorectal cancer. MATERIALS AND METHODS: Patients ≥70 years old who underwent surgical resection for stage I-III colorectal cancer between 2008 and 2013 were identified from the medical record. Sarcopenia was assessed by measuring the total muscle area on computerized tomography (CT) images obtained prior to surgery. Total muscle area was measured at the level of L3 and normalized using each patient's height to produce a skeletal muscle index (SMI). Sarcopenia was defined using sex- and body mass index (BMI)-specific threshold values of SMI. RESULTS: Eighty-seven patients were included, with a median age of 77 years (70-96). Twenty-five men (60% of 42) and 25 women (56% of 45) had sarcopenia. Sarcopenic patients had significantly lower BMI (p=0.03) compared to non-sarcopenic patients. There was a positive correlation between BMI and SMI for both men (r=0.44) and women (r=0.16). CONCLUSION: Sarcopenia is highly prevalent among older patients with early stage colorectal cancer. BMI alone is a poor indicator of lean body mass and improved methods of screening for sarcopenia are necessary. CT scans are a viable option for identifying sarcopenic patients in whom timely interventions may improve survival, quality of life, and functional outcomes.

Geriatric assessment-identified deficits in older cancer patients with normal performance status.

BACKGROUND: We investigated whether a brief geriatric assessment (GA) would identify important patient deficits that could affect treatment tolerance and care outcomes within a sample of older cancer patients rated as functionally normal (80%-100%) on the Karnofsky performance status (KPS) scale. METHODS: Cancer patients aged ≥65 years were assessed using a brief GA that included both professionally and patient-scored KPS and measures of comorbidity, polypharmacy, cognition, function, nutrition, and psychosocial status. Data were analyzed using descriptive statistics and multivariable logistic regression. RESULTS: The sample included 984 patients: mean age was 73 years (range: 65-99 years), 74% were female, and 89% were white. GA was conducted before (23%), during (41%), or after (36%) treatment. Overall, 54% had a breast cancer diagnosis (n = 528), and 46% (n = 456) had cancers at other sites. Moreover, 81% of participants (n = 796) had both professionally and self-rated KPS ≥80, defined as functionally normal, and those patients are the focus of analysis. In this subsample, 550 (69%) had at least 1 GA-identified deficit, 222 (28%) had 1 deficit, 140 (18%) had 2 deficits, and 188 (24%) had ≥3 deficits. Specifically, 43% reported taking ≥9 medications daily, 28% had decreased social activity, 25% had ≥4 comorbidities, 23% had ≥1 impairment in instrumental activities of daily living, 18% had a Timed Up and Go time ≥14 seconds, 18% had ≥5% unintentional weight loss, and 12% had a Mental Health Index score ≤76. CONCLUSION: Within this sample of older cancer patients who were rated as functionally normal by KPS, GA identified important deficits that could affect treatment tolerance and outcomes.

Feasibility of geriatric assessment in community oncology clinics.

OBJECTIVE: Emerging results support the value of geriatric assessment (GA) in determining the risk and benefits of cancer treatment in older adults. A brief GA tool consisting of valid and reliable measures has been developed; however, little data exist on the ability to perform the GA in community oncology clinics. The objective of this study was to determine the feasibility of performing the GA in the community. MATERIALS AND METHODS: Patients aged ≥65 were eligible. The GA included a health care provider assessment of performance status, cognitive function, a Timed Up and Go test, and a self-administered patient questionnaire that evaluated measures of functional status, comorbidity, psychological state, social support, and nutritional status. RESULTS: From 2009 to 2013, 1088 patients were assessed including 339 (31%) from seven community clinics across North Carolina. The median amount of time to complete the patient-report portion of the GA was 19min in the academic center versus 22min in the community. The median amount of time to complete the entire GA was 23min in the academic center and 30min in community settings. Significantly more patients in the community required assistance completing the questionnaire (24% vs. 14%); however, most patients required no assistance (76%). CONCLUSION: A brief GA can be performed in community oncology clinics. The time to complete the professional assessments and patient self-assessments were similar in both settings. Future studies are planned to determine if such assessments can improve cancer care for older patients.

Effect of cytotoxic chemotherapy on markers of molecular age in patients with breast cancer.

BACKGROUND: Senescent cells, which express p16 (INK4a) , accumulate with aging and contribute to age-related pathology. To understand whether cytotoxic agents promote molecular aging, we measured expression of p16 (INK4a) and other senescence markers in breast cancer patients treated with adjuvant chemotherapy. METHODS: Blood and clinical information were prospectively obtained from 33 women with stage I to III breast cancer at four time points: before anthracycline-based chemotherapy, immediately after anthracycline-based chemotherapy, 3 months after anthracycline-based chemotherapy, and 12 months after anthracycline-based chemotherapy. Expression of senescence markers p16 (INK4a) and ARF mRNA was determined using TaqMan quantitative reverse-transcription polymerase chain reaction in CD3(+) T lymphocytes, telomere length was determined by Southern analysis, and senescence-associated cytokines were determined by enzyme-linked immunosorbent assay. Findings were independently assessed in a cross-sectional cohort of 176 breast cancer survivors enrolled a median of 3.4 years after treatment; 39% previously received chemotherapy. All statistical tests were two-sided. RESULTS: In prospectively analyzed patients, expression of p16 (INK4a) and ARF increased immediately after chemotherapy and remained elevated 12 months after treatment. Median increase in log2 p16 (INK4a) was 0.81 (interquartile range = 0.28-1.62; Wilcoxon signed-rank P < .001), or a 75% absolute increase in expression, equivalent to the increase observed over 14.7 years of chronological aging. ARF expression was comparably increased (P < .001). Increased expression of p16 (INK4a) and ARF was associated with dose-dense therapy and hematological toxicity. Expression of two senescence-associated cytokines (VEGFA and MCP1) was durably increased by adjuvant chemotherapy. Telomere length was not affected by chemotherapy. In a cross-sectional cohort, prior chemotherapy exposure was independently associated with a log2-increase in p16 (INK4a) expression of 0.57 (repeated measures model, P < .001), comparable with 10.4 years of chronological aging. CONCLUSIONS: Adjuvant chemotherapy for breast cancer is gerontogenic, inducing cellular senescence in vivo, thereby accelerating molecular aging of hematopoietic tissues.
