Functional status in a geriatric oncology setting: A review

Predictors of three-month mortality and severe chemotherapy-related adverse events in patients aged 70 years and older with metastatic non-small-cell lung cancer: A secondary analysis of ESOGIA-GFPC-GECP 08-02 study

INTRODUCTION

Predictors for mortality and toxicity in older patients with cancer are mainly studied in cohorts with various cancers at different stages. This study aims to identify predictive geriatric factors (PGFs) for early death and severe chemotherapy related adverse events (CRAEs) in patients aged ≥70 years with metastatic non-small-cell lung cancer (mNSCLC).

MATERIAL AND METHODS

This is a secondary analysis of the multicenter, randomized, phase 3 ESOGIA trial that compared, for patients ≥70 years with mNSCLC, a treatment algorithm based on performance status and age to another algorithm based on geriatric assessment. To identify PGFs of three-month mortality and grade 3, 4, or 5 CRAEs, multivariate Cox models and logistic models, adjusted for treatment group and center, and stratified by randomization arm, were constructed.

RESULTS

Among 494 included patients, 145 (29.4%) had died at three months and 344 (69.6%) had severe chemotherapy toxicity. For three-month mortality, multivariate analyses retained mobility (Test Get up and Go), instrumental activity of daily living (IADL) dependence and weight loss as PGFs. The combined effect of IADL ≤2/4 and weight loss ≥3 kg was strongly associated with three-month mortality (adjusted hazard ratio: 5.71 [95% confidence interval [CI]: 2.64-12.32]). For chemotherapy toxicity, Charlson Comorbidity Index ≥2 was independently associated with grade3, 4, or 5 CRAEs (adjusted odds ratio [95% CI]: 1.94 [1.06-3.56]).

DISCUSSION

Mobility, IADL dependence, and weight loss were predictive of three-month mortality in a population aged ≥70 years treated for mNSCLC, while comorbidities were independently associated with severe chemotherapy toxicity.

Priority of the basic and instrumental activities of daily living in older patients with cancer prescribed rehabilitation: a cross-sectional survey

BACKGROUND

There is no information on whether vulnerable older patients with cancer consider basic activities of daily living (BADL) and instrumental activities of daily living (IADL) important outcomes. Our survey aimed to investigate the priority of BADL and IADL in outcomes among vulnerable older patients with cancer.

METHODS

This was a single-center survey in a Japanese cancer center. Eligible patients were ≥ 65 years of age and were prescribed in-hospital rehabilitation while under cancer treatment. Using original self-administered ranking questionnaires, patients were asked to rank outcomes and subdomain of BADL and IADL. High-priority domains were defined as the highest, second-highest, and third-highest priority domains in individuals.

RESULTS

A total of 169 patients were analyzed. The mean age was 74.0 years (standard deviation, 5.1 years) and the number of males was 107 (63%). The order of ranking of high-priority outcomes was BADL and IADL (n = 155), cognitive function (n = 91), mental function (n = 82), nutrition (n = 61), social function (n = 51), comorbidity (n = 39), and life span (n = 28). The top three high-priority independence subdomains of BADL and IADL were toilet use (n = 140), feeding (n = 134), and mobility (n = 69) among the BADL and shopping (n = 93), food preparation (n = 88), and ability to handle finances (n = 85) among the IADL.

CONCLUSIONS

BADL and IADL can be considered the most important health outcomes in clinical trials and in practice among older patients with cancer and physical vulnerabilities.

Functional status in older patients with cancer and a frailty risk profile: A multicenter observational study

INTRODUCTION

Functional status (FS) and frailty are significant concerns for older adults, especially those with cancer. Data on FS (Activities of Daily Living [ADL]; Instrumental Activities of Daily Living [IADL]) and its evolution during cancer treatment in older patients and a frailty risk profile are scarce. Therefore, this study examines FS and its evolution in older patients with cancer and a frailty risk profile and investigates characteristics associated with functional decline.

MATERIAL AND METHODS

This secondary data-analysis, focusing on FS, uses data from a large prospective multicenter observational cohort study. Patients ≥70 years with a solid tumor and a frailty risk profile based on the G8 screening tool (score ≤ 14) were included. A geriatric assessment was performed including evaluation of FS based on ADL and IADL. At approximately three months of follow-up, FS was reassessed. Univariable and multivariable logistic regression analyses were used to identify predictive factors for functional decline in ADL and IADL.

RESULTS

Data on ADL and IADL were available at baseline and follow-up in 3388 patients. At baseline 1886 (55.7%) patients were dependent for ADL, whereas 2085 (61.5%) patients were dependent at follow-up. Functional decline was observed in 23.6% of patients. For IADL 2218 (65.5%) patients were dependent for IADL, whereas 2591 (76.5%) patients were dependent at follow-up. Functional decline in IADL was observed in 41.0% of patients. In multivariable analysis, disease stage III or IV, comorbidities, falls history in the past twelve months, and FS measured by IADL were predictive factors for functional decline in both ADL and IADL. Other predictive factors for functional decline in ADL were polypharmacy, Eastern Cooperative Oncology Group-Performance Status (ECOG-PS) score 2-4, and cognitive impairment, and for functional decline in IADL were female sex, fatigue, and risk for depression.

DISCUSSION

Functional impairments are frequent in older persons with cancer and a frailty risk profile, and several characteristics are identified that are significantly associated with functional decline. Therefore, FS is an essential part of the geriatric assessment which should be standard of care for this patient population. Next step is to proceed with directed interventions with the aim to limit the risk of functional decline as much as possible.

Prognostic Impact of Postoperative Loss of Skeletal Muscle Mass in Patients Aged 70 Years or Older with Esophageal Cancer

BACKGROUND

The number of patients with esophageal cancer aged ≥ 70 years with a poor prognosis is increasing. In general patients with esophageal cancer, postoperative loss of skeletal muscle mass (SMM) is a prognostic factor. This study was designed to investigate the prognostic impact of postoperative loss of SMM in patients aged ≥ 70 years with esophageal cancer.

METHODS

This study was a single-center, retrospective cohort study. Patients with esophageal cancer who underwent R0 esophagectomy between 2016 and 2020 were included. The percentage postoperative loss of skeletal muscle mass index (SMI%) was calculated using computed tomography images before and at 4 ± 2 months after surgery.

RESULTS

The number of subjects in the ≥ 70-year and < 70-year age groups was 166 and 218, respectively. The median SMI% was 5% in all patients; thus, 5% was defined as the cutoff point to define major loss of SMI. Major loss of SMI impacted 3-year overall survival (OS) in the ≥ 70-year age group, independent of age, sex, clinical stage, pathological T and N factors, Charlson comorbidity index, and length of hospital stay (adjusted hazard ratio [HR]: 4.400; 95% confidence interval: 1.202-16.105; P = 0.025). The adjusted HR of major loss of SMI in the ≥ 70-year age group was higher than in the < 70-year age group (adjusted HR: 4.400 vs. 2.388, respectively).

CONCLUSIONS

Postoperative loss of SMI in patients with esophageal cancer aged ≥ 70 years more strongly impacted 3-year OS than in patients aged < 70 years.

Functional status in older patients with lung cancer: an observational cohort study

PURPOSE

An assessment of the impact of functional status (FS) evaluated using a combination of Activities of Daily Living (ADL) and the short version of the Instrumental Activities of Daily Living (IADL), on 3- and 6- month mortality and on 3-month unplanned hospitalizations in older patients treated for lung cancers.

METHOD AND OBJECTIVES

This observational retrospective study was conducted between September 2015 and January 2019 at Marseille University Hospital (AP-HM). During this period, all consecutive outpatients aged 70 years or older referred for a comprehensive geriatric assessment (CGA) before the initiation of lung cancer treatment were enrolled.

RESULTS

Two hundred twenty-seven patients were analyzed: the median age was 78.7 years and 74.0% were male. Almost half of the patients were metastatic (45.4%). Concerning FS, 41.9% of patients had no ADL-IADL impairment, 30.0% had either IADL or ADL impairment, and both ADL-IADL were impaired for 28.1%. Impaired ADL-IADL was associated with poor nutritional status, depression, mobility, and cognitive disorders. In a logistic regression model, ADL or IADL impairment (aOR = 2.1; 95% CI [1.0-4.2]; p = 0.037) and impaired ADL-IADL (aOR = 2.6; 95% CI [1.2-5.3]; p = 0.012) were independently associated with a higher risk of unplanned hospitalizations within 3 months. In the multivariate Cox model, 6-month mortality risk was independently associated with impaired ADL-IADL (aHR = 2.3; 95% CI [1.3-4.4]; p = 0.008).

CONCLUSION

The combination of ADL and IADL scales to assess FS is a prognostic marker of the mortality risk at 6 months in older patients with lung cancer and should be more largely used by oncologists in treatment decision making.

Self-Reported and Performance-Based Evaluations of Functional Status in Older Women With Breast Cancer

OBJECTIVES

To evaluate self-reported and performance-based functional status (FS) in older women with breast cancer according to stage and time of visit during treatment.

SAMPLE & SETTING

72 women with breast cancer aged 78 years or older and receiving any type of treatment at a midwestern outpatient clinic.

METHODS & VARIABLES

FS was evaluated using grip strength, the Index of Activities of Daily Living (ADLs), the instrumental ADLs (IADLs) scale, and the Timed Up and Go Test (TUGT). Mixed models were fit for grip strength and the TUGT, and generalized estimating equations were used to fit binary logistic regressions for the Index of ADLs and the IADLs scale. Continuous FS outcomes were evaluated using means and standard deviations.

RESULTS

Cancer stage and time of visit did not affect self-reported or performance-based FS scores. Most participants were considered independent on the Index of ADLs, the IADLs scale, and the TUGT, which did not change significantly between visits. Self-reported measures revealed less impairment.

IMPLICATIONS FOR NURSING

Monitoring FS using self-reported and performance-based measures can ensure that older patients receive timely support.

Functional status in older patients with cancer

BACKGROUND

Functional Status (FS) is an important domain in Comprehensive Geriatric Assessment (CGA) and is most often evaluated using the Activities of Daily Living (ADL) and Instrumental Activities of Daily Living (IADL) scales separately.

METHOD AND OBJECTIVES

This secondary analysis of a previous prospective cohort study was conducted between September 2015 and May 2018 at Marseille University Hospital, France, on 613 cancer outpatients aged ≥70 years. The first objective of this study was to determine the prevalence of FS impairment in older outpatients with cancer using a combination of the information collected with the ADL and short IADL scales. Our second objective was to describe the potential impact of this combined FS on three-month unplanned hospitalizations and three-month mortality in this population.

RESULTS

The median age was 81 years and 61.2% were men. The most common types of tumours were lung and thoracic (22.3%). Concerning FS, 255 patients (41.6%) had unimpaired ADL-IADL, 131 patients (21.4%) had IADL impairment, 38 patients (6.2%) had ADL impairment, and 189 patients (30.8%) had impaired ADL-IADL. In the multivariate Cox analysis, metastatic stage (adjusted Hazard Ratio (aHR) = 1.79; 95% CI [1.14-2.80]) and impaired ADL-IADL (aHR = 3.46; 95% CI [1.89-6.33]) were independently associated with three-month mortality. In the logistic regression model, impaired ADL-IADL (adjusted Odd ratio (aOR) = 3.64; 95% CI [1.84-7.20]) was the only factor independently associated with three-month unplanned hospitalizations.

INTERPRETATION

The combined use of the ADL and IADL scales to evaluate functional status in older patients with cancer is of significant prognostic value regarding the risks of three-month unplanned hospitalizations and mortality.

Distinctions Between Self-Report and Performance-Based Measures of Physical Function in Older Patients Prior to Chemotherapy

BACKGROUND

The maintenance of physical function (PF) is an extremely important outcome for elderly people.

OBJECTIVE

The aims of this study were to identify differences in the subjective and objective measures of PF between younger older adults (YOAs, 60-69 years of age) and older adults (OA, ≥70 years of age), to compare the PF scores with age-matched samples from the general population, and to evaluate for associations between the subjective and objective measures of PF.

METHODS

Patients (n = 139) were assessed using subjective (ie, European Organization for Research and Treatment of Cancer Core Quality-of-Life Questionnaire) and objective (ie, Short Physical Performance Battery [SPPB]) measures prior to chemotherapy (CTX). Data were analyzed using parametric and nonparametric tests.

RESULTS

No differences were found between the 2 age groups in any of the subjective or objective measures of PF. Compared with the age-matched general population, both YOAs and OAs had significantly lower scores in both measures of PF. Large effect sizes were found for differences in European Organization for Research and Treatment of Cancer Core Quality-of-Life Questionnaire role function, SPPB balance, and SPPB total scores between the YOA group and the age-matched general population samples. Correlations between the subjective and objective measures were low.

CONCLUSIONS

Older patients with cancer have lower PF than their age-matched general population prior to CTX. Longitudinal studies are warranted to evaluate for changes in PF during and following CTX.

IMPLICATIONS FOR PRACTICE

Nurses need to perform routine assessments of PF in older oncology patients prior to CTX. Our findings suggest that SPPB gait speed may be a useful screening measure for PF in older patients.

Characteristics Associated With Functional Changes During Systemic Cancer Treatments: A Systematic Review Focused on Older Adults

BACKGROUND

Maintaining functional status is important to older adults with cancer, but data are limited on how systemic treatments affect functional status. We systematically reviewed changes in functional status during systemic cancer treatments and identified characteristics associated with functional decline and improvement.

METHODS

We searched PubMed, Embase, Web of Science, and Cochrane Register of Controlled Trials for articles examining characteristics associated with functional changes in older adults during systemic cancer treatment published in English between database inception and January 11, 2019 (PROSPERO CRD42019123125). Findings were summarized with descriptive statistics. Study characteristics between older adult-specific and non-older adult-specific studies were compared using the Fisher exact test.

RESULTS

We screened 15,244 titles/abstracts and 519 full texts. The final analysis included 44 studies, which enrolled >8,400 patients; 39% of studies focused on older adults (1 study enrolled adults aged ≥60 years, 10 enrolled adults aged ≥65 years, and 6 enrolled adults aged ≥70 years). Almost all studies (98%) used patient-reported outcomes to measure functional status; only 20% used physical performance tests. Reporting of functional change was heterogeneous, with 48% reporting change scores. Older adult-specific studies were more likely to analyze functional change dichotomously (29% vs 4%; P=.008). Functional decline ranged widely, from 6% to 90%. The most common patient characteristics associated with functional decline were older age (n=7 studies), worse performance status (n=4), progressive disease status (n=4), pain (n=4), anemia (n=4), and worse nutritional status (n=4). Twelve studies examined functional improvement and identified 11 unique associated characteristics.

CONCLUSIONS

Functional decline is increasingly recognized as an important outcome in older adults with cancer, but definitions and analyses are heterogeneous, leading to a wide range of prevalence. To identify patients at highest risk of functional decline during systemic cancer treatments, trials need to routinely analyze functional outcomes and measure characteristics associated with decline (eg, nutrition).

Barthel Index-based functional status as a prognostic factor in young and middle-aged adults with newly diagnosed gastric, colorectal and lung cancer: a multicentre retrospective cohort study

OBJECTIVES

Functional status assessments of activities of daily living may improve prognostic precision during initial diagnostic evaluations in young and middle-aged adults with cancer. However, the association between pretreatment functional status and survival in these patients is poorly understood. This study aimed to evaluate the prognostic value of functional status in young and middle-aged patients with cancer.

DESIGN

Multicentre retrospective cohort study.

SETTING

We used a cancer registry from Osaka Prefecture, Japan. The data were linked to administrative claims data from 35 hospitals in the same prefecture.

PARTICIPANTS

Patients aged 18-69 years who received new diagnoses of gastric, colorectal or lung cancer between 2010 and 2014.

MAIN OUTCOME MEASURE

Cox proportional hazards models of 5-year all-cause mortality were developed to examine the prognostic impact of pretreatment functional status, which was categorised into three levels of functional disability (none, moderate and severe) based on Barthel Index scores. The models controlled for age, sex, comorbidities, cancer stage and tumour histology.

RESULTS

We analysed 12 134 patients. Higher mortality risks were significantly associated with moderate functional disability (adjusted HR 1.44 (95% CI 1.18 to 1.75), 1.35 (95% CI 1.08 to 1.68) and 1.74 (95% CI 1.50 to 2.03) in patients with gastric, colorectal and lung cancer, respectively) and severe functional disability (adjusted HR 3.56 (95% CI 2.81 to 4.51), 2.37 (95% CI 1.89 to 2.95) and 2.34 (95% CI 2.00 to 2.75) in patients with gastric, colorectal and lung cancer, respectively).

CONCLUSION

Accounting for functional status at cancer diagnosis may improve the prediction of survival time in young and middle-aged adults with cancer. Functional status has potential applications in survival predictions and risk adjustments when analysing outcomes in patients with cancer.

Impact of a comprehensive geriatric assessment on decision-making in older patients with hematological malignancies

OBJECTIVE

Hematological treatment decisions in older adults with hematological malignancies are complex. Our objective is to study the impact of a comprehensive geriatric assessment on hematological treatment decision in older patients and the factors associated with change in treatment plan.

METHODS

We conducted a cross-sectional analysis of patients aged 65 years and above with hematological malignancies, hospitalized between 2008 and 2019 at the University Cancer Institute of Toulouse. They were assessed by a geriatrician/nurse team using a comprehensive geriatric assessment (CGA). A penalized logistic regression model with elastic net regularization was used to identify factors associated with change in hematological treatment plan.

RESULTS

A total of 424 patients were included. Main hematological malignancies were lymphoma (36.1 %), acute myeloid leukemia (26.9 %) and myelodysplastic syndrome (19.8%). Change in hematological treatment plan was suggested after CGA for 92 patients (21.7%). Factors associated with change in treatment plan were functional impairment according to ADL and IADL scale, mobility impairment, the presence of comorbidity defined by the Charlson score >1 and increasing age.

CONCLUSION

A CGA has a significant impact on hematological treatment decision in older patients. Functional and mobility impairment, comorbidities and age are predictive factors of change in treatment plan.

Octogenarians treated for thoracic and lung cancers: Impact of comprehensive geriatric assessment

BACKGROUND

Lung cancer affects older and older old adults and is the leading cause of death by cancer. Comprehensive Geriatric Assessment (CGA) is recommended before and during cancer treatment to guide therapy management in this population.

METHODS

This study was conducted between September 2015 and January 2019 at Marseille University Hospital (AP-HM). During this period, all consecutive outpatients 70 years or older referred for a CGA before initiation of lung cancer treatment were enrolled. The objective of this study was to compare lung and thoracic cancer management of octogenarians (≥80 years) and their geriatric profile versus patients aged 70 to 79 years (<80 years).

FINDINGS

In our study, 228 patients were recruited. The median age was 78.7 ± 5 years. There were 94 octogenarians (41.2%), 36.2% of them were diagnosed with stage IV neoplasm and the most common treatment was chemotherapy (43.6%). The logistic regression analysis highlights that handgrip strength was the most commonly impaired domain (OR 2.3; 95% CI [1.3-4.3]) in octogenarians and that they are more likely than their younger counterparts to be treated by targeted therapy (OR 9.8; 95% CI [1.0-92.9]). Overall survival (OS) was similar in both age groups (log rank = 0,95).

INTERPRETATION

In our study, octogenarians and patients <80 years had equivalent survival, across the different thoracic cancer treatments and tumor stages. Measure of muscle strength in CGA could be very useful in a clinical setting to help improve the management of older old patients treated for lung or thoracic cancer.

Medication Reconciliation Associated with Comprehensive Geriatric Assessment in Older Patients with Cancer: ChimioAge Study

BACKGROUND

Polymorbidity induces polypharmacy in older patients may lead to potential drug-drug interactions (DDI) which can modify the tolerance and safety of oncological treatments and alter the intended therapeutic effect. The objective of our study was to describe the decision-making process for oncological treatment and related outcomes, in a population of older adults undergoing a comprehensive geriatric assessment (CGA) associated to a comprehensive medication reconciliation (CMR) prior to initiating oncological treatment.

METHODS

ChimioAge is a prospective observational study conducted between 01/2017 and 07/2018 at Marseille University Hospital and approved by the French National Ethics Committee. It comprised all consecutive patients aged 70 years and over who were referred for a CGA as part of CMR, before initiating systemic treatment.

RESULTS

One hundred and seventy-one cancer patients were included. Mean age was 79.2 years, over half had metastatic cancers, 75% had an ECOG performance status zero or one, and two-thirds were independent in daily activities. Two-thirds of the patients had polypharmacy and the CMR identified potential DDI with systemic treatment in 43.3% of patients. Following the CGA, the CMR and the hospital oncologists decision, 30% of the patients received adapted systemic treatment with reduced doses at initiation. They presented fewer toxicities - irrespective of grade and type - than patients who received standard treatment (p<0.001) and had comparable overall survival (Log rank p=0.21).

CONCLUSION

This is one of the first studies to highlight the value in conducting CMR and a CGA simultaneously before initiating systemic treatment in older patients with cancer. These two evaluations could give oncologists decisive information to personalize cancer treatment of older patients and optimize treatment dose to offer the best efficacy and minimize toxicity.

Capacity to Provide Geriatric Specialty Care for Older Adults in Community Oncology Practices

BACKGROUND

American Society of Clinical Oncology guidelines recommend that patients ≥65 years of age starting chemotherapy undergo a geriatric assessment (GA) to inform and guide management; however, little is known about resources available in community oncology practices to implement these guidelines and to facilitate geriatric oncology research.

MATERIALS AND METHODS

Oncology practices within the National Cancer Institute Community Oncology Research Program (NCORP) were electronically surveyed in 2017 regarding the availability of specialty providers, supportive services, and practice characteristics, as part of a larger survey of cancer care delivery research capacity.

RESULTS

Of the 943 NCORP practices, 504 (54%) responded to the survey, representing 210 practice groups. The median new cancer cases per year ≥65 years of age was 457 (interquartile range 227-939). Of respondents, only 2.0% of practices had a fellowship-trained geriatric oncologist on staff. Geriatricians were available for consultation or comanagement at 37% of sites, and of those, only 13% had availability within the oncology clinic (5% of overall). Practice size of ≥1,000 new adult cancer cases (ages ≥18) per year was associated with higher odds (1.81, confidence interval 1.02-3.23) of geriatrician availability. Other multidisciplinary care professionals that could support GA were variably available onsite: social worker (84%), nurse navigator (81%), pharmacist (77%), dietician (71%), rehabilitative medicine (57%), psychologist (42%), and psychiatrist (37%).

CONCLUSION

Only a third of community oncology practices have access to a geriatrician within their group and only 5% of community sites have access within the oncology clinic. Use of primarily self-administered GA tools that direct referrals to available services may be an effective implementation strategy for guideline-based care.

IMPLICATIONS FOR PRACTICE

Only a minority of community oncology practices in the U.S. have access to geriatric specialty care. Developing models of care that use patient-reported measures and/or other geriatric screening tools to assess and guide interventions in older adults, rather than geriatric consultations, are likely the most practical methods to improve the care of this vulnerable population.

High Serum Vitamin B12 Levels Associated with C-Reactive Protein in Older Patients with Cancer

BACKGROUND

A Comprehensive Geriatric Assessment (CGA) has been proposed to assess prognosis and to adapt oncological care in older patients with cancer. However, few biological markers are incorporated in the CGA.

METHODS

This comparative study on older patients with cancer was realized before final therapeutic decision and during a CGA that included biological markers. Our objective study was to know if the serum vitamin B12-C-reactive protein index (BCI) can help to estimate early death and unplanned hospitalization. Associations between BCI and unplanned hospitalization or mortality were analyzed using ordered multivariate logistic regression.

FINDINGS

We included 621 older cancer adults in outpatient care with a median age of 81 years (range, 70-98 years) from September 2015 to May 2018. In this study, 5.6% of patients died within 3 months, 8.8% had unplanned hospitalization within 1 month, and 11.4% had unplanned hospitalization within 3 months. Hypercobalaminemia was present in 83 patients (13.4%), and 34 patients (5.5%) had BCI >40,000. According to the multivariate analysis, BCI was a prognostic factor of mortality within 3 months and unplanned hospitalizations at 1 and 3 months. Impaired activities of daily living (ADL) and palliative care were also risk factors for mortality within 3 months. Impaired instrumental ADL, low albumin level, and palliative care were risk factors for unplanned hospitalization at 1 month.

INTERPRETATION

BCI could be routinely added to the CGA process, as part of a pretreatment workup, in order to assess more precisely the frailties and to adapt oncological care in older patients treated for cancer.

IMPLICATIONS FOR PRACTICE

Aging comes with an increase of frailties and comorbidities. To identify frailties in older patients with cancer, this study used a Comprehensive Geriatric Assessment, which allowed for the adaptation of each treatment plan in accordance with the individual needs of the patients. However, biological characteristics were not included in this assessment. This study showed that hypercobalaminemia and vitamin B12 -C-reactive protein index may be potential markers for cancer with poor prognosis, particularly in the older population. These biological markers can be used in geriatric oncology and general medicine.

Geriatric assessment domains to predict overall survival in older cancer patients: An analysis of functional status, comorbidities, and nutritional status as prognostic factors

Cancer treatments for older patients must account for heterogeneity in health and functional status. Guidelines advocate the use of geriatric assessments (GAs), but comprehensive assessments are laborious and the utility of specific GA domains remains unclear. The identification of specific domains as prognostic factors may support survival predictions and treatment decisions. We aimed to evaluate the associations between several GA domains and overall survival in older cancer patients. We linked cancer registry data and administrative claims data from cancer patients residing in Osaka Prefecture, Japan. The subjects were patients aged ≥70 years who received a diagnosis of gastric, colorectal, or lung cancer between 2010 and 2014 at 36 designated cancer care hospitals. The following three GA domains were assessed at cancer diagnosis: functional status through activities of daily living (ADL), comorbidities, and nutritional status through body mass index. Cox proportional hazards models were constructed for the three cancer types to estimate each domain's prognostic effect while adjusting for gender, age, and cancer stage. Adjusted hazard ratios (HRs) for all-cause mortality were calculated. We identified 5,559, 4,746, and 4,837 patients with gastric, colorectal, and lung cancer respectively. ADL impairment (HRs: 1.39-3.34, 1.64-2.86, and 1.24-3.21 for gastric, colorectal, and lung cancer, respectively), comorbidities (1.32-1.58, 1.33-1.97, and 1.19-1.29 for gastric, colorectal, and lung cancer, respectively), and underweight (1.36, 1.51, and 1.54 for gastric, colorectal, and lung cancer, respectively) were significantly associated with poorer overall survival. In contrast, overweight was significantly associated with improved overall survival (HRs: 0.82 and 0.89 for gastric and lung cancer respectively). The addition of the three domains increased the models' C-statistics (0.816 to 0.836, 0.764 to 0.787, and 0.759 to 0.783 for gastric, colorectal, and lung cancer respectively). Incorporating these factors into initial patient evaluations during diagnosis may aid prognostic predictions and treatment strategies in geriatric oncology.

Functional status and survival in patients ≥85 years of age who have keratinocyte carcinoma: A retrospective cohort study

BACKGROUND

Functional status assessment may help estimate which patients ≥85 years of age will benefit from surgical treatment for keratinocyte carcinoma (KC), but predictive value for short-term survival in this population has not been determined.

OBJECTIVE

We sought to assess the predictive value of functional status for short-term survival in patients ≥85 years of age who have KC.

METHODS

This was a retrospective cohort review of 238 patients ≥85 years of age who presented for the management of KC between 2010 and 2015. Functional status was assessed with the Karnofsky Performance Scale (KPS) and Katz Activities of Daily Living (ADL) index. Overall survival was determined.

RESULTS

Lower functional status scores of KPS ≤40 and Katz ADL ≤4 were associated with 37% and 53% survival at 2 years, respectively.

LIMITATIONS

Retrospective design and single-center study.

CONCLUSION

In this study, KPS and Katz ADL predicted short-term survival. Patients with low functional status scores had significantly decreased survival at 2 years, with double the death rate of patients with high functional status. Functional status should be considered during shared decision-making for elderly individuals who are seeking treatment for KC.

Functional Status, Supportive Care Needs, and Health-Related Quality of Life in Advanced Lung Cancer Patients Aged 50 and Older

Objective:

This study aimed to examine the levels of functional status, supportive care needs, and health-related quality of life (HRQOL), and their relationships reported by advanced lung cancer patients aged 50 and older.

Methods:

A cross-sectional descriptive correlational study was conducted with 103 participants recruited from a cancer center in Singapore. Functional status, supportive care needs, and HRQOL were measured using validated instruments. Descriptive statistics were used to describe the sample profiles. Univariate and multivariate regression analyses were adopted to determine factors that were associated with HRQOL.

Results:

About 70.9% of participants were dependent in at least one instrumental activities of daily living (IADL). The mean number of unmet needs rated by participants was 9 (range = 0–28). The top three ranked items with moderate-to-severe unmet needs were “not being able to do things you used to do” (28.2%), “fear about cancer spreading” (25.3%), and “lack of energy/tiredness” (25.2%). Higher IADL scores were significantly associated with better HRQOL, whereas higher levels of supportive care needs, particularly in psychological domain significantly predicted poorer HRQOL in most domains.

Conclusions:

This study found that poor functional status and unmet supportive care needs are common in advanced lung cancer patients. Psychological needs and functional status are associated with patients' HRQOL. Future interventions incorporating functional assistance and psychological support may increase HRQOL in this population.
