Validation of a Prediction Tool for Chemotherapy Toxicity in Older Adults With Cancer
Journal of clinical oncology : official journal of the American Society of Clinical Oncology, 2016
Older adults are at increased risk for chemotherapy toxicity, and standard oncology assessment measures cannot identify those at risk. A predictive model for chemotherapy toxicity was developed (N = 500) that consisted of geriatric assessment questions and other clinical variables. This study aims to externally validate this model in an independent cohort (N = 250). Patients age ≥ 65 years with a solid tumor, fluent in English, and who were scheduled to receive a new chemotherapy regimen were recruited from eight institutions. Risk of chemotherapy toxicity was calculated (low, medium, or high risk) on the basis of the prediction model before the start of chemotherapy. Chemotherapy-related toxicity was captured (grade 3 [hospitalization indicated], grade 4 [life threatening], and grade 5 [treatment-related death]). Validation of the prediction model was performed by calculating the area under the receiver-operating characteristic curve. The study sample (N = 250) had a mean age of 73...

Performance status (PS) scales such as the Eastern Cooperative Oncology Group (ECOG) PS and the Karnofsky Performance Index have limited utility in selecting therapies and predicting related adverse events in older patients with cancer. In July 2016, medical oncologists at our institution adopted the Cancer and Aging Research Group toxicity prediction score (CARG), a toxicity prediction tool, to identify patients who are "fit" for chemotherapy versus those who are "frail" and may experience severe complications. Methods Our retrospective review included referrals of beneficiaries 75 years of age and older who received standard systemic therapy and patients of the same age whose treatment was modified due to CARG. We compared the score's utilization six months before and after its incorporation and then assessed how its application impacted admissions, emergency department (ED) visits, and medical management. Results Thirty-eight patients with a mean age of 81 years met the inclusion criteria. Their diagnoses included gastrointestinal (37%), lung (21%), hematologic (18%), breast (10.5%), genitourinary (3%), and other (10.5%) malignancies. CARG was documented for 12.5% of systemic therapy recipients before its adoption and 41% of recipients after adoption. Its use was limited by the reliance on physicians to perform scoring during time-constrained patient encounters. Patients had fewer mean inpatient admissions (0.7 versus 2.3), admission days (4.3 versus 8), and ED visits (1.1 versus 2.5) when management was modified based on the score. Conclusion CARG assessment may facilitate a safer and more tailored approach to cancer care in older patients than conventional PS scales alone. Its integration into patient screening would increase its application and better define its potential predictive capacity to decrease risks for hospitalization.

ImportanceThe Cancer Aging Research Group (CARG) toxicity score is used to assess toxicity risk in geriatric patients receiving chemotherapy.ObjectiveThe primary aim was to validate the CARG score in geriatric patients treated with curative intent chemotherapy in predicting grade 3–5 toxicities.DesignThis was a longitudinal prospective observational study.SettingTata Memorial Hospital, Mumbai, India, a tertiary cancer care referral centre.ParticipantsPatients, aged ≥65 years, with gastrointestinal, breast or gynaecological stage I–III cancers being planned for curative intent chemotherapy. A total of 270 patients were required for accrual in the study.Exposure(s)Total risk score ranged from 0 (lowest toxicity risk) to 19 (highest toxicity risk).Main outcome(s) and measure(s)The primary endpoint of the study was to evaluate whether the CARG risk score predicted for grade 3–5 toxicities.ResultsThe study cohort of 270 patients had a mean age of 69 (65–83) years, with the most common ca...
Supportive Care in Cancer, 2018
Purpose It is recommended to use comprehensive geriatric assessment (CGA) in clinical oncology practice to improve care for geriatric cancer patients and to identify medical and social issues that may need further intervention. The purpose of this pragmatic pilot study was to evaluate the effectiveness of the Hurria et al. CGA in cancer patients 70 years of age or older undergoing adjuvant chemotherapy, as well as the feasibility of integrating it into a busy clinic practice and the psychosocial impact on these patients. Method Twenty-five patients were recruited. Descriptive analysis was performed via a geriatric assessment questionnaire completed by the participants prior to their first adjuvant chemotherapy treatment and during follow-up, 2 to 6 weeks after last treatment. Additionally, study staff performed a geriatric healthcare assessment at both time points. Results The results of this pilot study show that administration is feasible despite some challenges. Administration of a CGA in a clinic setting presented some logistical issues with regard to time and space available in clinic. Analysis of patient data indicated only minor variations in patient domains from pre-chemo to post-chemo confirming previous research. Participants expressed gratitude for the extra time spent with them at a stressful time in their lives. Conclusion Further information regarding the usefulness of a comprehensive geriatric assessment with regard to improving treatment selection, identifying undetected medical problems, and avoiding toxicity will be obtained if the administration of comprehensive geriatric questionnaires is incorporated into the clinic setting and considered into the allocated time for staff workload.

The elderly comprise the majority of patients with cancer and are the recipients of the greatest amount of chemotherapy. Unfortunately, there is a lack of data to make evidence-based decisions with regard to chemotherapy. This is due to the minimal participation of older patients in clinical trials and that trials have not systematically evaluated chemotherapy. This article reviews the available information with regard to chemotherapy and aging provided by a task force of the International Society of Geriatric Oncology (SIOG). Due to the lack of prospective data, the conclusions and recommendations made are a consensus of the participants. Extrapolation of data from younger to older patients is necessary, particularly to those patients older than 80 years, for which data is almost entirely lacking. The classes of drugs reviewed include alkylators, antimetabolites, anthracyclines, taxanes, camptothecins, and epipodophyllotoxins. Clinical trials need to incorporate an analysis of chem...
The impact of low-grade toxicity in older people with cancer undergoing chemotherapy
British Journal of Cancer
Background:Significant toxicity in chemotherapy trials is usually defined as grade ⩾3. In clinical practice, however, multiple lower grade toxicities are often considered meaningful. The purpose of this observational cohort study was to identify which level of toxicity triggers treatment modification and early discontinuation of chemotherapy in older people.Methods:Patients aged 65+ were recruited in a central London hospital. A total of 108 patients were recruited at the start of new chemotherapy treatment between October 2010 and July 2012.Results:Mean age was 72.1±5 years, median 72 and range 65-86 years. Of the patients, 50.9% (55) were male with gastrointestinal (49), gynaecological (18), lung (15) and other cancers (26). Chemotherapy was palliative in 59.3% (64/108), curative/ neoadjuvant/adjuvant in the others. Mean number of cycles completed was 4.2±3. Treatment modifications due to toxicity occurred in 60 (55.6%) patients, 35% (21/60) of whom had no greater than grade 2 tox...
Mastering chemotherapy dose reduction in elderly cancer patients
European Journal of Cancer, 2007
Cancer is mainly a disease of the elderly but clinical studies have generally excluded the elderly population for various reasons. Chemotherapy is one of the strongest weapons against (metastatic) cancer, but its use in the elderly has been limited due to fear of inducing toxicity. This review points out 10 recommendations that need to be taken into account when prescribing chemotherapy to elderly patients: aim of chemotherapy, specific pharmacological data for specific chemotherapeutics, treatment individualisation, alternatives to cytotoxic chemotherapy, comprehensive geriatric assessment, supportive therapy, hydration status, drug interactions, and compliance. Each of these topics will be reviewed here trying to give concrete recommendations for clinical practice.
Toxicity of Cancer Therapies in Older Patients
Current Oncology Reports, 2018
Purpose of the Review In clinical practice, older patients are often undertreated due to underrepresentation in clinical trials and fear of toxicity. Our objective was therefore to review toxicities that are specific to older cancer patients, to review risk factors in order to help physicians guide their decisions, and to review interventions that can be implemented in routine clinical practice to prevent toxicity induced by cancer therapies. Recent Findings On the whole, reviews report similar number and frequency as well as similar grade 3 or 4 adverse events between subjects older and younger than 65 years. Summary Yet patients included in clinical trials are often not representative of real-life patients and are often fit older cancer patients. Moreover, tolerance to the additive impact of multiple adverse effects is different between older and younger patients. And specific symptoms such as stomatitis may cause a series of consequences such as dehydration, denutrition, renal insufficiency, and adverse events of renally excreted drugs. Older patients are at high risk of toxicity due to many factors but mainly due to the prevalence of frailty in this population that has been estimated to be around 40% increasing the risk of chemotherapy intolerance. As a consequence, interventions must be implemented according to altered domains of comprehensive geriatric assessment in order to improve anticancer tolerance. These interventions are reviewed here.
