Age-related Differences in Symptoms and Their Interference with Quality of Life in 903 Cancer Patients Undergoing Radiation Therapy

Associations of frailty with symptoms, and HRQOL in older cancer survivors after cancer treatments: a systematic review and meta-analyses

PURPOSE

Frailty in older adult cancer survivors after cancer treatments is associated with various health outcomes. However, there is less agreement on how frailty affects symptoms and health-related quality of life (HRQOL). This systematic review and meta-analysis aimed to evaluate the current literature on frailty, symptoms, and HRQOL, as well as the associations of frailty with these factors in older adult cancer survivors with chemotherapy.

METHODS

A review was conducted on peer-reviewed publications from 2008 to 2023, using seven electronic databases. Meta-analyses were performed using random effects models to determine pooled effect estimates for frailty prevalence, symptom severity, and HRQOL scores.

RESULTS

A total of 26 studies involving older cancer survivors were included in the analysis. Most of these studies were conducted in Western countries and focused on White survivors, particularly those with breast cancer. The mean pooled prevalence of frailty was 43.5%. Among frail survivors, the most common symptoms reported after cancer treatments were pain (36.4%), neuropathy (34.1%), and fatigue (21.3%). Frailty was associated with higher pooled mean symptom severity (B = 1.23, p = 0.046) and lower functional HRQOL (B = - 0.31, p = 0.051, with marginal significance) after cancer treatments.

CONCLUSION

Frail older cancer survivors are at high risk of adverse symptoms and poor HRQOL after cancer treatment. Further research on screening for frailty is needed to prevent older adults from developing worse symptoms burden and maintain HRQOL. It is also essential to understand the mechanisms of the associations between frailty, symptoms and HRQOL in this population.

Prediction of gastrointestinal symptoms trajectories using omega-3 and inflammatory biomarkers in early-stage breast cancer patients receiving chemotherapy

PURPOSE

Gastrointestinal (GI) symptoms are common among breast cancer patients undergoing chemotherapy, negatively impacting treatment outcomes and quality of life. Evidence points to inflammatory processes as the underlying cause of chemotherapy-associated GI symptoms. Relatedly, omega-3 (n-3) has been linked to anti-inflammatory processes. The primary objective of this study was to examine the associations between baseline n-3, baseline inflammatory markers and GI symptom progression in early-stage breast cancer patients receiving chemotherapy.

METHODS

In this secondary analysis of a prospective cohort study, we analyzed baseline levels of inflammatory biomarkers (measured using a Luminex bead-immunoassay) and plasma levels of DHA, EPA, and FFA (measured using enzyme-linked immunosorbent assay). GI symptoms were assessed using the European Organisation for Research and Treatment of Cancer Quality of Life Questionnaire in Cancer Patients (EORTC QLQ-C30) symptom scale scores at baseline (T1) and at least 6 weeks after, during chemotherapy (T2). Inferential statistics were used to analyze associations between the variables of interest.

RESULTS

The analysis included 31 female breast cancer patients (mean age ± SD = 50.5 ± 8.8; 89.6% receiving anthracycline-based chemotherapy). Higher levels of docosahexaenoic acid (DHA) and interleukin-8 (IL-8) predicted increases in appetite loss. Similarly, higher IL-8 predicted worsened nausea and vomiting.

CONCLUSION

Baseline IL-8 and DHA predicted GI symptom progression in early-stage breast cancer patients undergoing chemotherapy. Future studies are required to evaluate how therapeutic intervention targeting these biomarkers may mitigate gastrointestinal symptoms in cancer patients.

Sleep dysfunction associated with worse chemotherapy-induced peripheral neurotoxicity functional outcomes

PURPOSE

Sleep problems are commonly reported by cancer survivors; however, knowledge of the impact of chemotherapy-induced peripheral neurotoxicity (CIPN) on sleep quality remains limited. In this study, we explored the impact of CIPN on sleep quality, as well as identified clinical characteristics associated with poor sleep quality.

METHODS

Participants were assessed cross-sectionally post-neurotoxic chemotherapy. CIPN severity was graded using a range of questionnaires that assessed CIPN severity and quality of life, as well as neurological grading scales. Sleep quality was assessed using a self-rated questionnaire (Pittsburgh Sleep Quality Index, PSQI). Participants with poor sleep quality were further grouped according to whether sleep impairment was due to CIPN or other factors.

RESULTS

Among 77 participants who reported CIPN, 75% (n = 58) reported poor sleep quality. Of those, 41% (n = 24) reported CIPN as contributing to sleep impairment, while 59% (n = 34) reported other causes. Participants with CIPN-induced sleep impairments had higher CIPN severity across all outcome measures, as well as greater neuropathic pain (all p < 0.05). Furthermore, participants with CIPN-induced sleep impairments reported worse impact of neuropathy on physical and social functioning, as well as emotional well-being (all p < 0.05).

CONCLUSIONS

Participants with CIPN-induced poor sleep quality reported worse scores across all CIPN severity measures. This emphasises the negative impacts of CIPN symptoms on quality of life of chemotherapy-treated patients and highlights the importance of sleep quality assessment in cancer survivors.

Cancer survivorship challenges of rural older adults: a qualitative study

BACKGROUND

Although research has advanced the field of oncologic geriatrics with survivors to assess their cancer-related needs and devise patient-centered interventions, most of that research has excluded rural populations. This study aimed to understand the survivorship challenges and recommendations in the perspective of rural older adults.

METHODS

This was a qualitative study that explored the survivorship challenges and recommendations of rural older adults who have completed curative intent chemotherapy for a solid tumor malignancy in the 12 months prior to enrollment in the present study.

RESULTS

Twenty-seven older adult survivors from rural areas completed open-ended semi-structured interviews. The mean age was 73.4 (SD = 5.0). Most participants were non-Hispanic White (96.3%), female (59.3%), married (63.0%), and had up to a high school education (51.9%). Rural older survivors reported a general lack of awareness of survivorship care plans, communication challenges with healthcare team, transportation challenges, financial toxicity, psychological challenges, and diet and physical challenges. Rural older survivors recommend the provision of nutritional advice referral to exercise programs, and social support groups and for their healthcare providers to discuss their survivorship plan with them.

CONCLUSIONS

Although study participants reported similar survivorship challenges as urban older adult survivors, additional challenges reported regarding transportation and consideration of farm animals have not been previously reported. Heightened awareness of the survivorship needs of rural older adults may result in better survivorship care for this population.

Functional decline and resilience in older adults over the age of 70 receiving radiotherapy for breast cancer: A pilot study

INTRODUCTION

Radiotherapy (RT) as an adjuvant, post-lumpectomy treatment has been shown to improve local control and survival in people with breast cancer. While adverse events because of cancer treatments are common, many older adults have demonstrated the ability to return to their baseline levels of physical functioning. There are limited reports on the functional decline and recovery of older patients undergoing RT. The primary objective of this study was to investigate physical function at various time points during RT in people with breast cancer over age 70 and their ability to recover post-decline.

MATERIALS AND METHODS

Seventy-nine patients with breast cancer aged 70+ undergoing adjuvant RT at Sunnybrook Health Science Centre, Toronto, Ontario, Canada were enrolled for a prospective observational study. Participants completed the EORTC QLQ-C30 quality of life questionnaire before their first RT, after their final RT, and at three- and six-months post-RT to assess changes in physical function. Descriptive statistics were utilized to evaluate EORTC QLQ-C30 scores. A higher score was indicative of poorer physical function. Physical decline was a 10+ point increase in EORTC QLQ-C30 score from baseline to the last RT, and resilience was a return to <10 points from the baseline score within six months post-RT. Resistance was a post-RT change from the baseline score by fewer than 10 points.

RESULTS

Nine patients (11%) experienced physical decline following their last RT, and two of them (22%) displayed resilience within six months. There were no demographic or symptom variables associated with functional decline from the baseline to post-RT, nor with resilience. Nausea, pain, and diarrhea post-RT were associated with functional decline at six months post-RT (P = 0.0185, P = 0.0449, P = 0.0007, respectively). Nausea and diarrhea at baseline were associated with resistance to decline (P = 0.0055, P = 0.019, respectively), and with decline at the six-month follow-up (P ≤0.0001, P = 0.0235, respectively).

DISCUSSION

This study highlights the incidence of physical decline in patients over age 70 receiving RT for breast cancer and identifies risk factors for decline. Future research with a larger sample, longer follow-up period, and incorporating geriatric assessments pre-RT is warranted to better understand functional decline and resilience in this population.

An Unsupervised Machine Learning Approach to Evaluating the Association of Symptom Clusters With Adverse Outcomes Among Older Adults With Advanced Cancer: A Secondary Analysis of a Randomized Clinical Trial

Importance

Older adults with advanced cancer who have high pretreatment symptom severity often experience adverse events during cancer treatments. Unsupervised machine learning may help stratify patients into different risk groups.

Objective

To evaluate whether clusters identified from baseline patient-reported symptom severity were associated with adverse outcomes.

Design, Setting, and Participants

This secondary analysis of the Geriatric Assessment Intervention for Reducing Toxicity in Older Patients With Advanced Cancer (GAP70+) Trial (2014-2019) included patients who completed the National Cancer Institute Patient-Reported Outcomes version of the Common Terminology Criteria for Adverse Events (PRO-CTCAE) before starting a new cancer treatment regimen and received care at community oncology sites across the United States. An unsupervised machine learning algorithm (k-means with Euclidean distance) clustered patients based on similarities of baseline symptom severities. Clustering variables included severity items of 24 PRO-CTCAE symptoms (range, 0-4; corresponding to none, mild, moderate, severe, and very severe). Total severity score was calculated as the sum of 24 items (range, 0-96). Whether the clusters were associated with unplanned hospitalization, death, and toxic effects was then examined. Analyses were conducted in January and February 2022.

Exposures

Symptom severity.

Main Outcomes and Measures

Unplanned hospitalization over 3 months (primary), all-cause mortality over 1 year, and any clinician-rated grade 3 to 5 toxic effect over 3 months.

Results

Of 718 enrolled patients, 706 completed baseline PRO-CTCAE and were included (mean [SD] age, 77.2 [5.5] years, 401 [56.8%] male patients; 51 [7.2%] Black and 619 [87.8%] non-Hispanic White patients; 245 [34.7%] with gastrointestinal cancer; 175 [24.8%] with lung cancer; mean [SD] impaired Geriatric Assessment domains, 4.5 [1.6]). The algorithm classified 310 (43.9%), 295 (41.8%), and 101 (14.3%) into low-, medium-, and high-severity clusters (within-cluster mean [SD] severity scores: low, 6.3 [3.4]; moderate, 16.6 [4.3]; high, 29.8 [7.8]; P < .001). Controlling for sociodemographic variables, clinical factors, study group, and practice site, compared with patients in the low-severity cluster, those in the moderate-severity cluster were more likely to experience hospitalization (risk ratio, 1.36; 95% CI, 1.01-1.84; P = .046). Moderate- and high-severity clusters were associated with a higher risk of death (moderate: hazard ratio, 1.31; 95% CI, 1.01-1.69; P = .04; high: hazard ratio, 2.00; 95% CI, 1.43-2.78; P < .001), but not toxic effects.

Conclusions and Relevance

In this study, unsupervised machine learning partitioned patients into distinct symptom severity clusters; patients with higher pretreatment severity were more likely to experience hospitalization and death.

Quality of life after treatment with immune checkpoint inhibitors for lung cancer; the impact of age

INTRODUCTION

Immune checkpoint inhibitors (ICIs) have revolutionized lung cancer treatment. However, it remains unclear as to whether changes in Health-Related Quality-of-Life (HRQoL) are associated with the age of lung cancer patients treated using ICIs. This study aimed to evaluate this possible association and to compare ICI-treated patients' HRQoL scores with normative data of an age-matched non-cancer general population.

METHODS

Lung cancer patients from the OncoLifeS data-biobank were included if they were treated with ICIs, irrespective of other treatments, at the University Medical Center Groningen between 2015 and 2021 and had completed the European Organization for Research and Treatment of Cancer Quality of Life Questionnaire C30 (EORTCQLQ-C30), both at the start of ICI treatment and after six months. Association of age as a continuous variable (per 10 years) and changes in HRQoL scores between baseline and 6 months was assessed using multivariable regression analyses. Clinical relevance of differences in HRQoL scores between OncoLifeS and the general population was classified into trivial, small, medium, and large, for three age groups (<60, 60-69 and ≥ 70 years).

RESULTS

151 patients were included with a mean age of 65.8 years. An increase in age per 10 years was associated with a larger decrease in the summary HRQoL score(β = -3.28,CI95%-6.42;-0.14), physical(β = -4.8, CI95% -8.71;-0.88), cognitive(β = -4.51,CI95%-8.24;-0.78), role functioning(β = -5.41,CI95%-10.78;-0.05), symptom burden(β = -3.66,CI95%-6.6;-0.73), and smaller negative changes in financial difficulties(β = 6.5 95 % CI 3.16; 9.85). OncoLifeS HRQoL scores were lower than those of the general population and differences were most often classified as large and medium.

CONCLUSION

Older lung cancer patients experience larger deteriorations in most HRQoL domains after 6 months of ICI treatment. Also, these patients showed significantly lower HRQoL scores compared to the general population.

Geriatric impairments are associated with reduced quality of life and physical function in older patients with cancer receiving radiotherapy - A prospective observational study

INTRODUCTION

Quality of life (QoL) and function are important outcomes for older adults with cancer. We aimed to assess differences in trends in patient-reported outcomes (PROs) during radiotherapy (RT) between (1) groups with curative or palliative treatment intent and (2) groups defined according to the number of geriatric impairments.

MATERIALS AND METHODS

A prospective observational study including patients aged ≥65 years receiving curative or palliative RT was conducted. Geriatric assessment (GA) was performed before RT, and cut-offs for impairments within each domain were defined. Patients were grouped according to the number of geriatric impairments: 0, 1, 2, 3, and ≥ 4. Our primary outcomes, global QoL and physical function (PF), were assessed by The European Organisation for Research and Treatment of Cancer Quality-of-Life Core Questionnaire (EORTC) (QLQ-C30) at baseline, RT completion, and two, eight, and sixteen weeks later. Differences in trends in outcomes between the groups were assessed by linear mixed models.

RESULTS

301 patients were enrolled, mean age was 73.6 years, 53.8% received curative RT. Patients receiving palliative RT reported significantly worse global QoL and PF compared to the curative group. The prevalence of 0, 1, 2, 3 and ≥ 4 geriatric impairments was 16.6%, 22.7%, 16.9%, 16.3% and 27.5%, respectively. Global QoL and PF gradually decreased with an increasing number of impairments. These group differences remained stable from baseline throughout follow-up without any clinically significant changes for any of the outcomes.

DISCUSSION

Increasing number of geriatric impairments had a profound negative impact on global QoL and PF, but no further decline was observed for any group or outcome, indicating that RT was mainly well tolerated. Thus, geriatric impairments per se should not be reasons for withholding RT. GA is key to identifying vulnerable patients in need of supportive measures, which may have the potential to improve treatment tolerance. Registered at clinicaltrials.gov (NCT03071640).

Fatigue During Cancer-Related Radiotherapy and Associations with Activities, Work Ability and Quality of Life: Paying Attention to Subgroups more Likely to Experience Fatigue

BACKGROUND

Having knowledge of which patients are more likely to experience fatigue during radiotherapy and the relationship between fatigue and health-related quality of life (HRQL) is important to improve identification and care of patients experiencing burdensome fatigue.

OBJECTIVE

To identify subgroups of patients, varying in situational, physiological, and psychological factors, who are more likely to experience fatigue an ordinary week of radiotherapy, and to compare patients experiencing and not experiencing fatigue regarding perceived HRQL and functional performance, that is, daily and physical activity and work ability.

METHODS

Cross-sectional study of 457 patients (52% women) undergoing radiotherapy (38% breast, 32% prostate cancer), using self-reported questionnaire data on fatigue, HRQL and functional performance analyzed using multivariable regression models.

RESULTS

Of the 448 patients who answered the fatigue question, 321 (72%) experienced fatigue. Patients reporting any comorbidity or depressed mood were more likely to experience fatigue, relative risk (RR) 1.56 ([95% confidence interval (CI)] 1.13-2.16) and RR 2.57 (CI 1.73-3.83), respectively. Patients with fatigue reported worse HRQL and performed less physical activity, including daily (P = .003), vigorous (P = .003) and moderate (P = .002) activity. Patients with and without fatigue reported 60% versus 40% sickness absence.

CONCLUSION

Patients with depressed mood or comorbidity were more likely to experience fatigue an ordinary week of radiotherapy than other patients were. Patients experiencing fatigue perceived worse HRQL and performed less daily and physical activity compared to patients not experiencing fatigue. Cancer care practitioners may consider paying extra attention to these subgroups of patients.

Palliative and Supportive Care for Individuals with Pancreatic Adenocarcinoma

Individuals with pancreatic adenocarcinoma experience a complex constellation of palliative and supportive care needs. Notably, when caring for patients with pancreatic adenocarcinoma, clinicians must carefully assess and address these individuals' palliative and supportive care needs, as these can have important implications related to their treatment experience and care outcomes. Importantly, prior research has consistently demonstrated the benefits of palliative and supportive care interventions for patients with cancer to help address symptom burden, illness understanding, coping mechanisms, and informed decision making. However, much of this research did not specifically tailor the interventions to the unique concerns of a pancreatic cancer population. Thus, an urgent need exists to design and conduct rigorous research with the goal of enhancing care delivery and outcomes for the highly symptomatic population of individuals with pancreatic adenocarcinoma.

Evaluation of the key geriatric assessment constructs in primary brain tumor population - a descriptive study

INTRODUCTION

Despite an increasing aging population, older adults (≥ 65 years) with primary brain tumors (PBTs) are not routinely assessed for geriatric vulnerabilities. Recent reports of geriatric assessment (GA) in patients with glioblastomas demonstrated that GA may serve as a sensitive prognosticator of overall survival. Yet, current practice does not include routine evaluation of geriatric vulnerabilities and the relevance of GA has not been previously evaluated in broader cohorts of PBT patients. The objective of this descriptive study was to assess key GA constructs in adults with PBT dichotomized into older versus younger groups.

MATERIALS AND METHODS

A cross-sectional analysis of data collected from 579 participants with PBT recruited between 2016 and 2020, dichotomized into older (≥ 65 years, n = 92) and younger (≤ 64 years, n = 487) from an ongoing observational trial. GA constructs were evaluated using socio-demographic characteristics, Charlson Comorbidity Index (CCI), polypharmacy (>5 daily medications), Karnofsky Performance Status (KPS), Neurologic Function Score (NFS), and patient-reported outcome assessments including general health, functional status, symptom burden and interference, and mood. Descriptive statistics, t-tests, chi-square tests, and Pearson correlations were used to evaluate differences between age groups.

RESULTS

Older participants were more likely to have problems with mobility (58% vs. 44%), usual activities (64% vs 50%) and self-care (38% vs 26%) compared to the younger participants (odds ratios [ORs] = 1.3-1.4, ps < 0.05), while older participants were less likely to report feeling distressed (OR = 0.4, p < 0.05). Older participants also had higher CCI and were more likely to have polypharmacy (OR = 1.7, ps < 0.05). Increasing age strongly correlated with worse KPS score (r = -0.232, OR = 1.4, p < 0.001) and worse NFS (r = 0.210, OR = 1.5, p < 0.001). No differences were observed in overall symptom burden, symptom interference, and anxiety/depression scores.

DISCUSSION

While commonly used GA tools were not available, the study employed patient- and clinician-reported outcomes to identify potential future research directions for the use of GA in the broader neuro-oncology population. Findings illustrate missed opportunities in neuro-oncology practice and underscore the need for incorporation of GA into routine care of this population. Future studies are warranted to further evaluate the prognostic utility of GA and to better understand functional aging outcomes in this patient population.

Characteristics and Assessment of Frailty as Risk Factor of Therapy-Related Acute Toxicities and Delayed Overall Treatment Time in Elderly Patients Treating with External Beam Radiation Therapy at Indonesia Top Referral Hospital

BACKGROUND: Older patients are at a higher risk of being frail. Frailty implies that even a minor stressor can have major negative implications on physical, psychological domains. Geriatric-8 (G-8) screening tool shows good screening properties for identifying vulnerable elderly patients with cancer. AIM: We, therefore, decided to investigate the utility of G-8 associated with acute toxicity and prolonged overall treatment time (OTT) in elderly cancer patients treated with radiotherapy (RT). MATERIALS AND METHODS: A prospective observational cohort study is performed. Eligible subjects are patients aged ≥60 years and were referred for curative or palliative RT. We use the G-8 questionnaire for consecutive patients before starting RT. We recorded acute toxicity and OTT and identified potential predictors. RESULTS: A total of 52 consecutive geriatric patients were included with an average age of 67 years. Of all those subjects, 21% had head-and-neck cancers, 29% gynecology cancers, 23% breast cancers, and 27% other cancers. According to the G-8, 65% of the patients were potentially frail. Toxicity Grade ≥3 was observed among 32% of subjects who were potentially frail according to the G-8 and 0% of the subject who was fit (p = 0.007). Prolonged OTT was observed in 61.8% of potentially frail and 27.8% of the subjects who were fit (p = 0.020). On multivariate analysis, only chemoradiation was strongly associated with acute toxicity Grade ≥3 odds ratio 11.1 (95% confidence interval 1.4–83.6; p = 0.019). CONCLUSION: The utility of G-8 in daily practice seems to be limited. Only concurrent chemoradiation was associated with acute toxicity. Future prospective studies should investigate whether the G-8 is a good predictor for other relevant clinical outcomes and survival in our local settings.

A text messaging intervention and quality of life in adolescents with solid organ transplants

BACKGROUND

Facilitating communication between adolescents and HCP outside of appointments may enhance patient experience and outcomes. The purpose of this study was to determine whether SMS enhances the healthcare experience, QoL, and medication adherence in adolescent SOT patients.

METHODS

This was a prospective observational study of an SMS platform (WelTel Inc) for SOT patients aged 12-19 years. QoL was assessed before and after using the PedsQL™ Transplant Module. Medication adherence was assessed with the frequency of therapeutic tacrolimus levels and variation based on control chart analysis. Patient experience and engagement was evaluated with surveys, response rate to messages, and number of clinical conversations (>2 messages).

RESULTS

Twenty-three patients were included (median age 15.7 years (IQR 13.6-17.1)). Median intervention duration was 13.5 months (range 4.0-16.7 months). There was a 68% response rate (742/1095) with 375 clinical conversations. The majority of patients reported the intervention provided a positive outlook on their health (17/23), was useful (18/23), and improved their connection to HCPs (17/23). Following the intervention, there was no significant difference in the median scaled QoL scores (pre-intervention: 81 (IQR 76.5-93.3), post-intervention: 78 (IQR 76-93); p = .37), mean percentage of therapeutic tacrolimus levels (pre-intervention: 52 ± 25%, post-intervention: 65 ± 17%; p = .07), or variation on control chart analysis of tacrolimus levels.

CONCLUSIONS

The WelTel messaging platform provided supplemental clinical care for a group of adolescent SOT patients that enhanced their healthcare experience. Patient QoL and adherence were unchanged following the intervention and remained at a high level.

The Impact of Aging on Symptom Prevalence and Management in Terminally ill Patients With Cancer

CONTEXT

With global population aging, the number of older patients with cancer is increasing. However, few data are available on palliative care for these patients.

OBJECTIVES

To evaluate differences in symptom prevalence and the need for medical interventions among patients of different ages in a palliative care unit.

METHODS

In this retrospective analysis, a consecutive sample of 1032 terminally ill patients with cancer were categorized into the following age ranges: <70, 70-79, 80-89, and ≥90 years. We evaluated symptom prevalence, the need for palliative medicines, opioid dose on the day before death, and the need for palliative sedation. Trend tests were used to examine whether the prevalence of findings increased or decreased with age.

RESULTS

As age increased, significant decreasing trends were observed in the prevalence of pain, dyspnea, fatigue, constipation, nausea, drowsiness, difficulty sleeping, anxiety, and dysuria but not in appetite loss, edema, sputum production, or delirium. As age increased, significant decreasing trends were also observed in the need for opioids, benzodiazepines, antiemetics, and anticholinergics. The median opioid doses in the <70, 70-79, 80-89, and ≥90 years age groups were 118, 72, 48, and 48 mg oral morphine equivalents/day, respectively (P < 0.0001). The need for palliative sedation showed a significant decreasing trend as age increased (P < 0.0001).

CONCLUSION

We found age to be inversely related to symptom prevalence and medical interventions among terminally ill patients with cancer, contributing to the understanding of the experience of older patients with cancer.

Alleviating Excessive Worries Improves Co-Occurring Depression and Pain in Adolescent and Young Adult Cancer Patients: A Network Approach

OBJECTIVE

Anxiety, depression, and pain are highly interactive with each other in adolescent and young adult (AYA) cancer patients. This study aims to map out the connectivity between anxiety, depression and pain symptoms amongst Chinese AYA cancer patients from the perspective of a network model.

METHODS

Two hundred and eighteen AYA patients, aged between 15 and 39 years at diagnosis; completed the Patient Health Questionnaire (PHQ), Generalized Anxiety Disorder (GAD), and McGill Pain Questionnaire-Visual Analogue Scale (MPQ-VAS). Network analyses were performed.

RESULTS

In all, 38.07% (95% CI = 31.58-44.57%) of the participants reported depression, 30.73% (95% CI = 24.56-36.91%) reported anxiety, and 14.22% (95% CI = 9.55-18.89%) reported current pain. The generated network illustrated that anxiety, depression and pain community were well connected. In the network, "having trouble relaxing" (GAD4, node strength = 1.182), "uncontrollable worry" (GAD2, node strength = 1.165), and "sad mood" (PHQ2, node strength = 1.144) were identified as the most central symptoms, while "uncontrollable worry" (GAD2, bridge strength = 0.645), "guilty" (PHQ6, bridge strength = 0.545), and "restlessness" (GAD5, bridge strength = 0.414) were the key bridging symptoms that connected different communities.

CONCLUSION

Anxiety, depression and pain symptoms are highly interactive with each other. Alleviating AYA cancer patient's excessive worries might be helpful in improving the patient's co-occurring anxiety, depression and pain symptoms.

Geriatric assessment with management for older patients with cancer receiving radiotherapy. Protocol of a Norwegian cluster-randomised controlled pilot study

About 50% of patients with cancer are expected to need radiotherapy (RT), and the majority of these are older. To improve outcomes for older patients with cancer, geriatric assessment (GA) with management (GAM) is highly recommended. Evidence for its benefits is still scarce, in particular for patients receiving RT. We report the protocol of a cluster-randomised pilot study designed to test the effect, feasibility and health economic impact of a GAM intervention for patients ≥65 years, referred for palliative or curative RT. The randomising units are municipalities and city districts. The intervention is municipality-based and carried out in collaboration between hospital and municipal health services from the start of RT to eight weeks after the end of RT. Its main constituents are an initial GA followed by measures adapted to individual patients' impairments and needs, systematic symptom assessments and regular follow-up by municipal cancer nurses, appointed to coordinate the patient's care. Follow-up includes at least one weekly phone call, and a house call four weeks after the end of RT. All patients receive an individually adapted physical exercise program and nutritional counselling. Detailed guidelines for management of patients' impairments are provided. Patients allocated to the intervention group will be compared to controls receiving standard care. The primary outcome is physical function assessed by the European Organisation of Research and Treatment of Cancer Quality of Life Questionnaire C-30. Secondary outcomes are global quality of life, objectively tested physical performance and use of health care services. Economic evaluation will be based on a comparison of costs and effects (measured by the main outcome measures). Feasibility will be assessed with mixed methodology, based on log notes and questionnaires filled in by the municipal nurses and interviews with patients and nurses. The study is carried out at two Norwegian RT centres. It was opened in May 2019. Follow-up will proceed until June 2022. Statistical analyses will start by the end of 2021. We expect the trial to provide important new knowledge about the effect, feasibility and costs of a GAM intervention for older patients receiving RT. Trial registration: ClinTrials.gov, ID NCT03881137, initial release 13th of March 2019.

The effect of age on health-related quality of life for head and neck cancer patients up to 1 year after curative treatment

OBJECTIVES

The aim was to evaluate the effect of age on health-related quality of life (HRQOL) for patients with head and neck cancer (HNC), treated with curative intent, in the Western healthcare region of Sweden.

MATERIALS AND METHODS

In this prospective observational study, 311 HNC patients completed quality of life questionnaires for cancer (EORTC QLQ-C30 and EORTC QLQ-H&N35) and for older patients with cancer (EORT QLQ-ELD14) at diagnosis and 3, 6, and 12 months after start of treatment. Mean scores for patients ≥70 years old were compared to younger patients (50 to 69 years old) to assess differences in HRQOL.

RESULTS

Of the 311 study participants, 105 patients were ≥70 years old (median age 76.7), of which 32 were ≥80 years of age. Most HRQOL scores were equal or better for older adult patients at 3 months after treatment, but physical function was better for younger adult patients up to 12 months after treatment. At 6 months the HRQOL was similar (older patients had less appetite loss and financial difficulties), while the oldest patients (≥80 years) had worse fatigue, role function, and feeling ill at 12 months. For the EORTC-ELD-14 questionnaire, older patients scored better for worries at diagnosis and reported more difficulties in maintaining purpose at 12 months after treatment.

CONCLUSION

When curative treatment is administered, older adult patients with HNC have similar or even better HRQOL compared to younger adult patients, except for physical function, during the first year.

Pain, symptom distress, and pain barriers by age among patients with cancer receiving hospice care: Comparison of baseline data

OBJECTIVES

Age group differences have been reported for pain and symptom presentations in outpatient and inpatient oncology settings, but it is unknown if these differences occur in hospice. We examined whether there were differences in pain, symptom distress, pain barriers, and comorbidities among three age groups (20-64 years, 65-84 years, and 85+) of hospice patients with cancer.

MATERIALS AND METHODS

Participants were recruited from two hospices. Half were women; 49% White and 34% Black. 42% were 20-64 y, 43% 65-84 y, and 15% 85+ y. We analyzed baseline data for 230 hospice patients with cancer (enrolled 2014-2016, mean age 68.2 ± 14.0, 20-100 years) from a stepped-wedge randomized controlled trial. Measures were the Average pain intensity (API, 0-10: current, least and worst pain intensity during the past 24 h), Symptom Distress Scale (SDS, 13-65), Barriers Questionnaire-13 (BQ-13, 0-5), and comorbid conditions. Descriptive, bivariate association, and multiple regression analyses were performed.

RESULTS

Mean API scores differed (p < .001) among the three age groups (5.6 ± 2.0 [20-64 years], 4.7 ± 2.0 [65-84 years], and 4.4 ± 1.8 [85+], as did the mean SDS scores (36.1 ± 7.3, 33.5 ± 8.1, and 31.6 ± 6.6, p = .004). BQ-13 mean scores (2.6 ± 0.9, 2.7 ± 0.8, and 2.5 ± 0.7) and comorbidities were not significantly different across age groups. In multiple regression analyses, age-related differences in API and SDS remained significant after adjusting for gender, race, cancer, palliative performance score, and comorbidities. Comorbidities were positively associated with SDS (p = .046) but not with API (p = .64) in the regression model.

CONCLUSION

Older hospice patients with cancer reported less pain and symptoms than younger patients, but all groups reported similar barriers to pain management. These findings suggest the need for age- and race-sensitive interventions to reduce pain and symptom distress levels at life's end.

Older Age: A Protective Factor Against Perceived Dignity-Related Distress in Patients With Advanced Cancer?

CONTEXT

Most older adults will face threats to loss of health and social support, which can affect their perceived dignity. Although problems with perceived dignity increase in the context of cancer, the specific experience for those older compared with younger patients with advanced cancer has not been described despite its contributions to the wish to hasten death (WTHD).

OBJECTIVES

To understand the influence of age group to the perception of dignity, considering changes in quality of life and the WTHD in patients with advanced cancer.

METHODS

The Patient Dignity Inventory was administered to 194 patients with advanced cancer. The data were analyzed by separating the sample into age groups younger than 65 years (N = 106) or 65 years and older (N = 88). Linear regression models were adjusted with the explanatory variables of WTHD, quality of life, as well as functional status, physical dependence, depression, anxiety, and sociodemographic variables.

RESULTS

Older patients showed a 2.6% decrease in the total scores of perceived dignity-related distress compared to younger patients.

CONCLUSION

Older age could be a protective factor against the perception of loss of dignity in patients with advanced cancer, a more positive perspective of the aging experience.

Symptoms and factors associated with symptom clusters among older adults with oral and oropharyngeal cancers at diagnosis

OBJECTIVE: Describe differences in pretreatment symptoms and the composition of symptom clusters in older patients with oral and oropharyngeal cancer. METHODS: In this cross-sectional study, quality of life (QoL) assessments for cancer patients (EORCT QLQ-C30 and QLQ-H & N35) were applied to 161 cases of oral and oropharyngeal cancer at the time of enrollment in an outpatient clinic. They were used to evaluate QoL-related symptoms reported by patients, according to their occurrence. To identify symptom clusters, an exploratory factor analysis (EFA) was performed, and the relationships between these clusters and independent variables were assessed with linear regression models. RESULTS: The most prevalent symptoms were pain (52%), worry (48%), and weight loss (44%). Five factors were extracted from the EFA, of which 3 were noteworthy. The dysphagia cluster was common to both cancer sites, although more frequent in oropharyngeal cancer patients, and included symptoms such as difficulty swallowing, pain, and weight loss. The psychological cluster included symptoms related to feeling worried, nervous, and depressed. The asthenia cluster, in addition to being age-related, may represent the advanced stage or progression of the disease. CONCLUSION: The dysphagia cluster loaded the most symptoms and was common to both cancers. In addition to pain (one of the main symptoms of the dysphagia cluster), psychological symptoms were also important in both groups of patients. Adequate and early control of these symptom clusters at diagnosis could favor better management of symptoms during treatment.

Personalised treatment for older adults with cancer: The role of frailty assessment

It is widely accepted in clinical practice that chronological age is a poor predictor of treatment tolerance and outcomes in older adults with cancer. Intrinsic vulnerability is more a function of underlying frailty, rather than chronological age. Frailty is a state of increased vulnerability to stressors, such as cancer and its treatment, which can lead to adverse health outcomes for patients. Capturing this heterogeneity in reserve capacity is the cornerstone of management in geriatricmedicine, but remains poorly understood or adopted in radiation oncology. A two-step approach, using a shorter screening tool, followed by full assessment for those who need it, is the mostresourceful way of implementing frailty assessment in radiotherapy departments. It is important for radiation oncology professionals to identify frailty and to use this information in multidisciplinary decision making in order to develop a personalised radiotherapy approach for the older person. There are many ways we can effectively use this information, such as considering treatment fractionation schedules that would limit the burden of travel for those with social frailty, or reviewing the range of modalities at our disposal, which might limit toxicity in the older person at high risk of deterioration during treatment. Frailty assessment is not carried out in many radiotherapy departments presently, but there are many international models to use as exemplars as to how it may be implemented in clinical practice. There are many opportunities for further research and role development in this field at the current time.

Moderate hypofractionated helical tomotherapy for prostate cancer in a cohort of older patients: a mono-institutional report of toxicity and clinical outcomes

PURPOSE OR OBJECTIVE

To evaluate toxicity and outcomes of moderately hypofractionated helical tomotherapy for the curative treatment of a cohort of patients aged ≥ 75 years with localized prostate cancer (PC).

MATERIALS AND METHODS

From January 2013 to February 2017, 95 patients with median age 77 years (range 75-88) were treated for PC. 39% were low risk, 33% intermediate risk (IR), 28% high risk (HR). Median iPSA was 9.42 ng/ml (1.6-107). Androgen deprivation was prescribed according to NCCN recommendations. All patients received 70 Gy in 28 fractions to the prostate; 61.6 Gy were delivered to the seminal vesicles for IR; whole pelvis irradiation with a total dose of 50.4 Gy was added in the HR group. Toxicity evaluation was based on CTCAE V4.0 criteria, biochemical failure was defined following Phoenix criteria. Quality of Life was assessed with the EPIC-26 index. Overall survival and biochemical failure-free survival were analysed with Kaplan-Meier method.

RESULTS

With a median follow-up of 36 months (range 24-73), acute and late toxicity were acceptable. No correlation between toxicity patterns and clinical or dosimetric parameter was registered. EPIC-26 showed a negligible difference in urinary and bowel function post-treatment that did not reach statistical significance. The 2- and 3-years OS were 93% and 87% with cancer specific survival of 97.9% and 96.2%.

CONCLUSION

Moderate hypofractionated RT reported excellent outcomes in our cohort of older patients. Shorter schedules may be proposed regardless of chronological age facilitating the treatment compliance in the older population.

The association between health-related quality of life and achievement of personalized symptom goal

PURPOSE

The aim of study was to explore the potential association between patient's self-reported physical symptom management goals as personalized symptom goal (PSGs) and health-related quality of life (HRQOL) in cancer patients. The secondary outcome was to investigate the relationship between number of physical symptoms not achieving the PSGs and HRQOL in cancer patients.

METHODS

This single-center prospective observational study comprised 140 consecutive outpatients. We evaluated the PSGs and HRQOL using the Functional Assessment of Cancer Therapy-General (FACT-G). Patients were administered a self-report questionnaire, including reports on their physical symptom intensity and PSGs using Edmonton Symptom Assessment System-revised (ESAS-r) scores. We investigated the correlation between PSGs achievement (ESAS-r score ≤ PSG score) and FACT-G total scores, and relationship between and number of physical symptoms not achieving the PSGs (ESAS-r score > PSG score) and FACT-G total scores.

RESULTS

The patients who did not achieve PSGs of pain, tiredness, lack of appetite, and shortness of breath had a lower FACT-G total score (p < 0.05). Multivariate linear regression showed that higher number of physical symptoms not achieving the PSGs correlated with lower FACT-G scores (decreasing by 1.826 points for each such symptom, p < 0.01). Predictors of increased number of physical symptoms not achieving the PSGs were younger age and a higher symptom intensity of anxiety.

CONCLUSION

PSGs achievement was associated with HRQOL in cancer patients. Additionally, the number of unachieved PSGs were independent determinant of poor HRQOL, particularly in younger cancer patients and those with higher symptom intensity of anxiety.

Age-related differences in patient-reported and objective measures of chemotherapy-induced peripheral neuropathy among cancer survivors

PURPOSE

While older adults with cancer are more likely to develop chemotherapy-induced peripheral neuropathy (CIPN), the study aimed to determine if patient-reported and objective measures of CIPN differ by age among cancer survivors.

METHODS

Cancer survivors with persistent CIPN after completion of platinum and/or taxane chemotherapy completed CIPN questionnaires (severity, interference with activities, sensory, and motor symptoms) and objective testing (light touch, vibration, pain, cold sensation). CIPN measures were compared by age group (< 65 n = 260 versus ≥ 65 n = 165) using parametric and nonparametric tests.

RESULTS

Among 425 cancer survivors with CIPN, mean age was 60.9 (SD 10.5). CIPN location did not differ by age (overall 68% hands and feet, 27% only feet, 5% only hands). For patient-reported measures, older survivors reported less severe pain in the hands and feet than younger survivors. In addition, older survivors reported lower interference with general activity, routine activities, normal work, enjoyment of life, sleep, mood, relations with other people, and sexual activity. No age differences in sensory and motor symptom scores were found. In contrast, for objective measures, older survivors had worse light touch and cold sensations in their feet and worse vibration detection in their hands and feet.

CONCLUSIONS

Despite having worse light touch, cold, and vibration sensations, older cancer survivors with CIPN reported less severe pain and interference with activities. This discordance highlights the importance of including both patient-reported and objective measures to assess CIPN in cancer survivors to better evaluate this clinical condition.

Association Between Symptom Burden and Physical Function in Older Patients with Cancer

OBJECTIVES

To evaluate the independent association between symptom burden and physical function impairment in older adults with cancer.

DESIGN

Cross-sectional.

SETTING

Two university-based geriatric oncology clinics.

PARTICIPANTS

Patients with cancer aged 65 years or older who underwent evaluation with geriatric assessment (GA).

MEASUREMENTS

Symptom burden was measured as a summary score of severity ratings (range = 0-10) of 10 commonly reported symptoms using a Clinical Symptom Inventory (CSI). Functional impairment was defined as the presence of one or more impairments of instrumental activities of daily living (IADLs), any significant physical activity limitation on the Medical Outcomes Survey (MOS), one or more recent falls in the previous 6 months, or a Short Physical Performance Battery (SPPB) score of 9 or less. Multivariate analysis evaluated the association between symptom burden and physical function impairment, adjusting for other clinical and sociodemographic variables.

RESULTS

From 2011 to 2015, 359 patients with cancer and a median age of 81 years (range = 65-95 y) consented. The mean CSI score was 23.2 ± 20.5 with an observed range of 0 to 90. Patients in the highest quartile of symptom burden (N = 91; CSI score 52 ± 13) had a higher prevalence of IADL impairment (91% vs 51%), physical activity limitation (93% vs 65%), falls (55% vs 21%), and SPPB score of 9 or less (92% vs 69%) (all P values <.01) when compared with those in the bottom quartile (N = 81; CSI score: 2 ± 2). With each unit increase in CSI score, the odds of having IADL impairment, physical activity limitations, falls, and SPPB scores of 9 or less increased by 4.8%, 4.4%, 2.9%, and 2.5%, respectively (P < .05 for all results).

CONCLUSIONS

In older patients with cancer, higher symptom burden is associated with functional impairment. Future studies are warranted to evaluate if improved symptom management can improve function in older cancer patients. J Am Geriatr Soc 67:998-1004, 2019.

Age-related differences in patient-reported outcomes in patients with advanced lung cancer receiving anti-PD-1/PD-L1 therapy

BACKGROUND

Older adults with lung cancer often have comorbidities that may increase risk of symptomatic adverse events (AEs) and physical function decline. The objective of this study was to examine age-related differences in patient-reported symptoms and functional domains in patients with advanced lung cancer receiving immunotherapy drugs.

METHODS

Three randomized controlled trials of anti-programmed death receptor-1/programmed death-ligand 1 therapy in patients with advanced non-small cell lung cancer that included patient-reported outcomes (PROs) were identified. Baseline PRO data were pooled for treatment arms from 2 trials that included the same PRO tools. Age-related differences in baseline mean scores for each of the health-related quality of life functional and symptom scales were assessed for patients ≥70 years and <70 years. Mean change from Baseline at 3 months was also calculated and plotted for each age group. The adequacy of PRO assessments was assessed by comparing clinician-reported AE data in the 3 trials to the item content of the PRO tools included.

RESULTS

Across the 3 trials, 75 of patients were under 70 and 26% patients were 70 and older. Comparing baseline scores in the 2 trials with the same PRO tool, older adults reported small differences including lower physical functioning, less pain, insomnia and financial difficulties, and higher social functioning than younger patients at baseline. No large differences in the distributions of mean change from baseline in function or symptom were identified. Several common clinician-reported symptomatic AEs were not assessed by the PRO strategy employed in the 3 trials. Three clinician-reported symptomatic AEs (rash, fever, and pruritus) that were commonly reported in the safety data (9%-19%) were not assessed using the PRO tools employed.

CONCLUSION

While several small differences were seen, there did not appear to be large differences at baseline or in the distributions of change from baseline in PRO functional domains between younger and older patients with lung cancer undergoing anti-programmed death receptor -1/programmed death-ligand 1 therapy. Relevant symptomatic side effects were not assessed by PRO measures in these trials, and this is a limitation of current PRO assessment strategies.

Prevalence of physical problems detected by the distress thermometer and problem list in patients with breast cancer

BACKGROUND

Patients with breast cancer have high rates of physical symptoms that negatively impact their quality of life. The relationship between women's perceptions of these physical symptoms and patient demographic and breast cancer characteristics is less well known. This study describes physical symptoms of patients with breast cancer and their relationship with patient characteristics.

METHODS

Patients (n = 125) with breast cancer (stage 0-IV) completed questionnaires in a dedicated academic medical center breast cancer clinic. Patients reported demographics (age, race/ethnicity, marital status, and employment status) and disease characteristics (surgery type, receipt of chemotherapy, or antihormonal therapy). Patients reported whether they were bothered by any of the 22 physical problem list (PPL) variables from the distress thermometer and problem list.

RESULTS

The median number of physical problems endorsed by patients was 3.0 (M = 3.43, SD = 3.42). Approximately one-fourth endorsed no physical symptoms while three-fourths reported at least 1 problem, and three-fifths endorsed 2 or more problems. Fatigue (40.0%), sleep (34.7%), skin dry/itchy (22.9%), pain (19.5%), and feeling swollen (19.5%) were most commonly reported. Age, race/ethnicity, marital status, employment status, and receipt of chemotherapy were associated with certain physical problems. Problems with breathing, eating, memory/concentration, nausea, and total number of endorsed PPL variables were associated with distress.

CONCLUSION

The breast cancer population demonstrates heavy physical symptom burden with multiple physical problems that are related to overall functioning. Special attention should be given to the physical symptom burden of younger, nonwhite, unmarried, and unemployed patients. Future research should investigate the PPL of the distress thermometer and problem list with other measures of symptom burden.

Factors Influencing Global Health Related Quality of Life in Elderly Cancer Patients: Results of a Secondary Data Analysis

Cancer treatment for elderly patients is often complicated by poor physical condition, impaired functioning and comorbidities. Patient reported health related quality of life (HRQOL) can contribute to decisions about treatment goals and supportive therapy. Knowledge about factors influencing HRQOL is therefore needed for the development of supportive measures and care pathways. An exploratory secondary data analysis on 518 assessments of the European Organisation for Research and Treatment of Cancer (EORTC) core questionnaire (EORTC QLQ-C30) and the elderly module (EORTC QLQ-ELD14) was performed to identify factors predictive for global HRQOL. Preliminary simple and multivariable regression analyses were conducted resulting in a final model comprising sociodemographic and disease specific variables and scales of the QLQ-C30 and QLQ-ELD14. Age, sex and disease related variables explained only part of the variance of global HRQOL (adjusted R2 = 0.203). In the final model (adjusted R2 = 0.504) fatigue, social function, burden of illness and joint stiffness showed possible influence on global HRQOL. Fatigue, social function and burden of illness seem to have the largest impact on global HRQOL of elderly cancer patients. Further prospective studies should examine these domains. Actionable symptoms should be given special attention to initiate targeted supportive measures aiming to maximize HRQOL of older cancer patients.

Quality of life of elderly patients with solid tumours undergoing adjuvant cancer therapy: a systematic review

OBJECTIVES

The measurement of quality of life (QoL) in elderly cancer population is increasingly being recognised as an important element of clinical decision-making and the evaluation of treatment outcome. This systematic review aimed to summarise the evidence of QoL during and after adjuvant therapy in elderly patients with cancer.

METHODS

A systematic search was conducted of studies published in CINAHL plus, CENTRAL, PubMed, PsycINFO and Web of Science from the inception of these databases to December 2016. Eligible studies included RCTs and non-RCTs in which QoL was measured in elderly patients (aged 65 years or above) with stage I-III solid tumours who were undergoing adjuvant chemotherapy and/or radiotherapy. Because of the heterogeneity and the insufficient data among the included studies, the results were synthesised narratively.

RESULTS

We included 4 RCTs and 14 non-RCTs on 1785 participants. In all four RCTs, the risk of bias was low or unclear for most items but high for detection. Of the 14 non-RCTs, 5 studies were judged to have a low or moderate risk of bias for all domains, and the other 9 studies had a serious risk of bias in at least one domain. The bias was observed mainly in the confounding and in the selection of participants for the study. For most elderly patients with breast cancer, the non-significant negative change in the QoL was transient. A significant increase in the QoL during the course of temozolomide in elderly patients with glioblastoma but a decreasing trend in QoL after radiotherapy was shown. This review also shows a uniform trend of stable or improved QoL during adjuvant therapy and at follow-up evaluations across the studies with prostate, colon or cervical cancer population.

CONCLUSIONS

This review suggests that adjuvant chemotherapy and radiotherapy may not have detrimental effects on QoL in most elderly patients with solid tumours.

Association of demographic, economic and clinical variables in daily activities and symptoms presented by patients in cancer treatment

OBJECTIVE

To investigate the association between demographic, economic and clinical variables, cancer symptoms, and daily life interference in patients receiving cancer treatment in Brazil.

METHODS

In this cross-sectional study, 268 patients were assessed. A questionnaire was used to collect data on demographic, economic and clinical variables, and the M.D. Anderson Symptom Inventory was used to assess cancer symptoms. Data were analyzed using bivariate and multivariate descriptive statistics.

FINDINGS

The following variables were associated with higher symptom scores: female sex (prevalence ratio [PR]=1.28; 95% confidence interval [95% CI] 1.06-1.53), illiteracy or ≤ 9 years of formal education (PR=1.40; 95% CI 1.08-1.82), clinical equipment or situations that requiring nursing care (PR=1.23; 95% CI 1.03-1.46), and family history of cancer (PR=1.23; 95% CI 1.04-1.45). Daily life interference was associated with female sex (PR=1.40; 95% CI 1.12-1.75), secondary tumour (PR=1.42; 95% CI 1.16-1.74) and radiotherapy (PR=1.24; 95% CI 1.01-1.51).

CONCLUSION

Management of cancer patients requires multidisciplinary knowledge, taking into consideration all the subjective dimensions of the patients. Knowing the profile of patients most strongly affected by symptoms will help them face the limitations and consequences of the disease and its treatment.

Liens entre les variables démographiques, économiques et cliniques et les symptômes rapportés par les patients en cours de traitement contre le cancer

Objectif

Examiner le lien entre les variables démographiques, économiques et cliniques, les symptômes de cancer et les entraves aux activités quotidiennes chez des patients brésiliens recevant des traitements contre le cancer.

Méthodologie

La présente étude transversale s’est penchée sur le cas de 268 patients, qui ont dû répondre à un questionnaire recueillant des données démographiques, économiques et cliniques, en plus d’évaluer leurs symptômes à l’aide de l’inventaire de symptômes MD Anderson (MD Anderson Symptom Inventory – MDASI). Les données ont été soumises à des analyses statistiques descriptives bivariées et multivariées.

Résultats

Les variables suivantes étaient associées à des symptômes plus prononcés : sexe féminin (taux de prévalence [TP]=1,28; intervalle de confiance de 95 % [IC 95 %], 1,06-1,53); analphabétisme ou ≤ 9 années de scolarité formelle (TP=1,40; IC 95 %, 1,08–1,82); équipement médical ou situations nécessitant des soins infirmiers (TP=1,23; IC 95 %, 1,03–1,46); antécédents familiaux de cancer (TP=1,23; IC 95 %, 1,04–1,45). Les entraves aux activités quotidiennes étaient associées aux facteurs suivants : sexe féminin (TP=1,40; IC 95 %, 1,12–1,75); tumeur secondaire (TP=1,42; IC 95 %, 1,16–1,74), radiothérapie (TP=1,24; IC 95 %, 1,01–1,51).

Conclusion

La gestion des patients atteints de cancer nécessite des connaissances multidisciplinaires qui tiennent compte de toutes leurs dimensions subjectives. En connaissant le profil des patients vivant les symptômes les plus intenses, nous pourrons les aider à s’adapter aux limites et aux conséquences qu’entraînent la maladie et le traitement.

Assessment and management of radiotherapy induced toxicity in older patients

Radiotherapy is an attractive treatment option for older adults, especially where surgery and chemotherapy pose too great a risk. Radiotherapy toxicity may be divided into acute/early and late effects of treatment. The latter may have limited relevance to an older patient with competing causes of mortality due to significant comorbidity. Altered fractionation regimes have been employed in numerous sites, with no significant toxicity impact. These offer greater convenience in the elderly, especially those with limited social support or in active caregiving roles. As radiotherapy toxicity is site specific, it's important to assess baseline function via Comprehensive Geriatric Assessment (CGA), and any pre-existing comorbidities that may influence toxicity. With modern radiotherapy technology and capabilities, these are less of an issue and radiotherapy is a very suitable treatment option for the older adult. When evaluating the literature on toxicity in older patients, it's important to recognise that older studies do not represent modern day radiotherapy techniques and capabilities. Advanced technology may simultaneously deliver enhanced target coverage and reduced toxicity. More research is required related to the predictive power of CGA in linking radiotherapy toxicity to frailty. What little evidence exists shows that CGA has a role in treatment of older patients with radiotherapy and that, in general, radiotherapy appears to be well tolerated in older adults. The purpose of this review is to provide a broad overview of the mechanisms of normal tissue reactions to radiotherapy and how radiation induced toxicity may affect older patients.

Age differences in fatigue, decrements in energy, and sleep disturbance in oncology patients receiving chemotherapy

OBJECTIVE

The number of older adults with cancer is increasing. Given the limited amount of research and the inconsistent findings regarding age differences in common physical symptoms associated with cancer and its treatments, the purposes of this study, in a sample of oncology outpatients receiving chemotherapy (CTX), were to evaluate for age differences in demographic and clinical characteristics, as well as in occurrence rates of and severity ratings for fatigue, decrements in energy, and sleep disturbance. In addition, using regression analysis techniques, within and across age groups, demographic and clinical characteristics associated with the severity of each symptom were evaluated.

METHODS

Patients (n = 1343) were dichotomized into younger (<65 years) and older (≥65 years) age groups. Patients completed self-report questionnaires prior to their next dose of CTX.

RESULTS

Overall, our findings suggest that compared to younger patients, older adults experience a lower or similar level of fatigue, decrements in energy, and sleep disturbance. However, it should be noted that both age groups experienced high occurrence rates and moderate to severe levels of all three symptoms.

CONCLUSIONS

Clinicians need to assess all oncology patients receiving CTX for these three symptoms. Future research needs to determine the biopsychosocial reasons that underlie these age-related differences in fatigue, decrements in energy, and sleep disturbance.

Linguistic Validation of the M. D. Anderson Symptom Inventory in Persian-Speaking Iranian Cancer Patients

CONTEXT

Various symptoms frequently affect cancer patients' quality of life. Appropriate assessment of these symptoms provides valuable data for cancer management.

OBJECTIVES

This study aimed to validate the Persian version of the M. D. Anderson Symptom Inventory (MDASI-P).

METHODS

This cross-sectional study was conducted at four cancer treatment centers in two cities in Iran. Breast cancer and colorectal cancer patients aged 18 years and older were consecutively included in the study. The standard forward-backward translation method was applied. Patients completed the MDASI-P along with the previously validated Persian version of the European Organization for Research and Treatment of Cancer Quality of Life Questionnaire-Core 30 (EORTC QLQ-C30). Construct validity (factor analysis), criterion validity (against the EORTC QLQ-C30), and reliability (Cronbach's alpha) were analyzed.

RESULTS

A total of 146 breast cancer and 94 colorectal cancer patients were studied. Factor analysis for the symptom severity items resulted in a three-factor solution, further reduced to a two-factor solution: general symptoms and gastrointestinal symptoms. Correlation of the MDASI-P symptom severity items with corresponding EORTC QLQ-C30 symptom items (r = 0.48-0.75) and MDASI-P interference items with corresponding EORTC QLQ-C30 functioning domains (r = -0.46 to -0.23) supported the criterion validity. Cronbach's alpha was 0.90, 0.88, and 0.77 for the total questionnaire, symptom severity items, and the interference subscale, respectively.

CONCLUSION

The MDASI-P is a feasible, valid, and reliable instrument for evaluation of symptoms in Persian-speaking cancer patients and can be used to improve symptom management in these patients.

Population-level trends in posttreatment cancer survivors' concerns and associated receipt of care: results from the 2006 and 2010 LIVESTRONG surveys

There is a need to better understand the posttreatment concerns of the nearly 14 million survivors of cancer alive in the United States today and their receipt of care. Using data from 2,910 posttreatment survivors of cancer from the 2006 or 2010 LIVESTRONG Surveys, the authors examined physical, emotional, and practical concerns, receipt of care, and trends in these outcomes at the population level.

RESULTS

89% of respondents reported at least one physical concern (67% received associated posttreatment care), 90% reported at least one emotional concern (47% received care), and 45% reported at least one practical concern (36% received care). Female survivors, younger survivors, those who received more intensive treatment, and survivors without health insurance often reported a higher burden of posttreatment concerns though were less likely to have received posttreatment care. These results reinforce the importance of posttreatment survivorship and underscore the need for continued progress in meeting the needs of this population. Efforts to increase the availability of survivorship care are extremely important to improve the chances of people affected by cancer living as well as possible in the posttreatment period.

Differences in the symptom experience of older oncology outpatients

CONTEXT

The relatively low number of older patients in cancer trials limits knowledge of how older adults experience symptoms associated with cancer and its treatment.

OBJECTIVES

This study evaluated for differences in the symptom experience across four older age groups (60-64, 65-69, 70-74, ≥75 years).

METHODS

Demographic, clinical, and symptom data from 330 patients aged >60 years who participated in one Australian and two U.S. studies were evaluated. The Memorial Symptom Assessment Scale was used to evaluate the occurrence, severity, frequency, and distress of 32 symptoms commonly associated with cancer and its treatment.

RESULTS

On average, regardless of the age group, patients reported 10 concurrent symptoms. The most prevalent symptoms were physical in nature. Worrying was the most common psychological symptom. For 28 (87.5%) of the 32 Memorial Symptom Assessment Scale symptoms, no age-related differences were found in symptom occurrence rates. For symptom severity ratings, an age-related trend was found for difficulty swallowing. As age increased, severity of difficulty swallowing decreased. For symptom frequency, age-related trends were found for feeling irritable and diarrhea, with both decreasing in frequency as age increased. For symptom distress, age-related trends were found for lack of energy, shortness of breath, feeling bloated, and difficulty swallowing. As age increased, these symptoms received lower average distress ratings.

CONCLUSION

Additional research is warranted to examine how age differences in symptom experience are influenced by treatment differences, aging-related changes in biological or psychological processes, or age-related response shift.

Examining the cost-effectiveness of radiation therapy among older women with favorable-risk breast cancer

BACKGROUND

Little is known about the cost-effectiveness of external beam radiation therapy (EBRT) or newer radiation therapy (RT) modalities such as intensity modulated radiation (IMRT) or brachytherapy among older women with favorable-risk breast cancer.

METHODS

Using a Markov model, we estimated the cost-effectiveness of no RT, EBRT, and IMRT over 10 years. We estimated the incremental cost-effectiveness ratio (ICER) of IMRT compared with EBRT under different scenarios to determine the necessary improvement in effectiveness for newer modalities to be cost-effective. We estimated model inputs using women in the Surveillance, Epidemiology, and End Results-Medicare database fulfilling the Cancer and Leukemia Group B C9343 trial criteria.

RESULTS

The incremental cost of EBRT compared with no RT was $9500 with an ICER of $44600 per quality-adjusted life year (QALY) gained. The ICERs increased with age, ranging from $38300 (age 70-74 years) to $55800 (age 80 to 94 years) per QALY. The ICERs increased to more than $63800 per QALY for women aged 70 to 74 years with an expected 10-year survival of 25%. Reduction in local recurrence by IMRT compared with EBRT did not have a substantial impact on the ICER of IMRT. IMRT would have to increase the utility of baseline state by 20% to be cost-effective (<$100000 per QALY).

CONCLUSIONS

EBRT is cost-effective for older women with favorable risk breast cancer, but substantially less cost-effective for women with shorter expected survival. Newer RT modalities would have to be substantially more effective than existing therapies in improving quality of life to be cost-effective.

Differences in the symptom experience of older versus younger oncology outpatients: a cross-sectional study

Background

Mortality rates for cancer are decreasing in patients under 60 and increasing in those over 60 years of age. The reasons for these differences in mortality rates remain poorly understood. One explanation may be that older patients received substandard treatment because of concerns about adverse effects. Given the paucity of research on the multiple dimensions of the symptom experience in older oncology patients, the purpose of this study was to evaluate for differences in ratings of symptom occurrence, severity, frequency, and distress between younger (< 60 years) and older ( ≥ 60 years) adults undergoing cancer treatment. We hypothesized that older patients would have significantly lower ratings on four symptom dimensions.

Methods

Data from two studies in the United States and one study in Australia were combined to conduct this analysis. All three studies used the MSAS to evaluate the occurrence, severity, frequency, and distress of 32 symptoms.

Results

Data from 593 oncology outpatients receiving active treatment for their cancer (i.e., 44.4% were < 60 years and 55.6% were ≥ 60 years of age) were evaluated. Of the 32 MSAS symptoms, after controlling for significant covariates, older patients reported significantly lower occurrence rates for 15 (46.9%) symptoms, lower severity ratings for 6 (18.9%) symptoms, lower frequency ratings for 4 (12.5%) symptoms, and lower distress ratings for 14 (43.8%) symptoms.

Conclusions

This study is the first to evaluate for differences in multiple dimensions of symptom experience in older oncology patients. For almost 50% of the MSAS symptoms, older patients reported significantly lower occurrence rates. While fewer age-related differences were found in ratings of symptom severity, frequency, and distress, a similar pattern was found across all three dimensions. Future research needs to focus on a detailed evaluation of patient and clinical characteristics (i.e., type and dose of treatment) that explain the differences in symptom experience identified in this study.

Prevalence, putative mechanisms, and current management of sleep problems during chemotherapy for cancer

Sleep problems are highly prevalent in cancer patients undergoing chemotherapy. This article reviews existing evidence on etiology, associated symptoms, and management of sleep problems associated with chemotherapy treatment during cancer. It also discusses limitations and methodological issues of current research. The existing literature suggests that subjectively and objectively measured sleep problems are the highest during the chemotherapy phase of cancer treatments. A possibly involved mechanism reviewed here includes the rise in the circulating proinflammatory cytokines and the associated disruption in circadian rhythm in the development and maintenance of sleep dysregulation in cancer patients during chemotherapy. Various approaches to the management of sleep problems during chemotherapy are discussed with behavioral intervention showing promise. Exercise, including yoga, also appear to be effective and safe at least for subclinical levels of sleep problems in cancer patients. Numerous challenges are associated with conducting research on sleep in cancer patients during chemotherapy treatments and they are discussed in this review. Dedicated intervention trials, methodologically sound and sufficiently powered, are needed to test current and novel treatments of sleep problems in cancer patients receiving chemotherapy. Optimal management of sleep problems in patients with cancer receiving treatment may improve not only the well-being of patients, but also their prognosis given the emerging experimental and clinical evidence suggesting that sleep disruption might adversely impact treatment and recovery from cancer.
