Validation of a Prediction Tool for Chemotherapy Toxicity in Older Adults With Cancer.

ABSTRACT: 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 years (range, 65 to 94 [standard deviation, 5.8]). More than one half of patients (58%) experienced grade ? 3 toxicity. Risk of toxicity increased with increasing risk score (36.7% low, 62.4% medium, 70.2% high risk; P < .001). The area under the curve of the receiver-operating characteristic curve was 0.65 (95% CI, 0.58 to 0.71), which was not statistically different from the development cohort (0.72; 95% CI, 0.68 to 0.77; P = .09). There was no association between Karnofsky Performance Status and chemotherapy toxicity (P = .25).This study externally validated a chemotherapy toxicity predictive model for older adults with cancer. This predictive model should be considered when discussing the risks and benefits of chemotherapy with older adults.

Project description:PURPOSE:Older patients with colon cancer (CC) are vulnerable to chemotherapy toxicity and death. Establishing simple scores specific for patients with CC to predict severe chemotoxicity or early death is needed to select the best treatment strategy. SUBJECTS, MATERIALS, AND METHODS:This prospective multicenter study included patients aged ?70 years with CC receiving adjuvant or first-line metastatic chemotherapy. Frailty markers (nutrition, physical activity, energy, mobility, strength), comprehensive geriatric assessment (functional status, comorbidities, falls, nutrition, cognition, and depression), and usual laboratory parameters were collected. Logistic or Cox regression was used to examine at 500 days the association between frailty markers, comprehensive geriatric assessment, laboratory parameters, and grade 3-4 toxicity or death. RESULTS:A total of 97 patients (median age, 79.0 years) received adjuvant (37.1%) or metastatic (62.9%) chemotherapy. During the first 500 days, grade 3-4 toxicity occurred in 49.5%, and 30% died. The predictive model for grade 3-4 toxicity combined (polychemotherapy × 3) + (hypoalbuminemia <32 g/L × 2) + (abnormal grip strength × 1.5) + C-reactive protein >11 mg/L + Eastern Cooperative Oncology Group performance status (ECOG-PS), cutoff score >3. The predictive model for death combined (metastasis × 5) + (age × 2) + alkaline phosphatase >100 IU/mL + sex (female) + abnormal grip strength + ECOG-PS, cutoff score >6. For chemotoxicity prediction, sensitivity was 81.6% and specificity 71.4%. For death prediction, sensitivity was 89.7% and specificity was 83.6%. CONCLUSION:These simple and efficient "ColonPrediscores" will help to better identify older patients with CC with increased risk of chemotherapy-related toxicity and/or death. IMPLICATIONS FOR PRACTICE:The two scores assessed in this study, called "ColonPrediscores", offer a major advantage in that they do not need a previous complete geriatric assessment, which makes them an easy-to-use tool in oncologic settings.

Project description:ImportanceHearing loss affects up to 88% of patients undergoing head and neck cancer treatment; however, there are few validated models to predict this outcome. A predictive posttreatment model for hearing loss will allow clinicians and patients to make well-informed decisions about treatment with cisplatin-based chemotherapies and radiotherapy.ObjectiveTo validate a previously created predictive model for objective hearing outcomes and to assess barriers to using the prediction nomogram in general practice for patients newly diagnosed with head and neck cancer.Design, setting, and participantsThis cohort study includes an evaluation of 105 patients (208 ears) and interviews with 6 clinicians. The patients were treated at a high-volume tertiary care hospital. Patient participants were newly diagnosed with head and neck cancer and treated at Siteman Cancer Center from July 1, 2018, to December 31, 2019, with radiotherapy both with and without cisplatin-based chemotherapy. Additionally, the clinicians involved in the care of patients with head and neck cancer were interviewed to assess implementation strategies.ExposuresRadiotherapy with and without cisplatin-based chemotherapy.Main outcomes and measuresHearing defined by the audiometric pure-tone average of 1, 2, and 4 kHz.ResultsA total of 105 patients (208 ears; mean [SD] age, 61 [11] years; 82 men [78%]) were compared with the development cohort to assess the similarities and differences in case mix. All patients underwent radiation therapy, 50 (48%) received cisplatin-based chemotherapy, and 67 (64%) had a surgical resection. The mean (SD) cochlear dose of radiation was 13 (12) Gy, and the mean (SD) total cisplatin dose was 238 (83) mg/m2 for those undergoing cisplatin therapy. A calibration curve demonstrated that predicted and observed posttreatment pure-tone average were not significantly different. The model predicted a posttreatment pure-tone average greater than 35 dB (a common threshold for hearing aid consideration) with a sensitivity of 73% and specificity of 67% with an area under the curve of 0.71, showing good discrimination. Clinician interviews suggest the nomogram requires careful integration into patient counseling to clarify risks and benefits for treatment.Conclusions and relevanceThe findings of this cohort study confirm this model's ability to predict posttreatment hearing outcomes in a unique population of patients. This model has the potential to inform pretreatment counseling and posttreatment hearing evaluations for this patient population.

Project description:BACKGROUND:The decision whether to treat older adults with advanced cancer with standard therapy (ST) or reduced therapy (RT) is complicated by heterogeneity in aging. We assessed the potential utility of the chemotherapy toxicity risk score (CTRS) [J Clin Oncol 2011;29:3457-3465] for treatment decisions in older adults. MATERIALS AND METHODS:This was a prospective observational study of patients aged ?65 years receiving first-line chemotherapy for advanced cancer for which combination chemotherapy is the standard of care. Patients were categorized as high risk (CTRS ?10), for whom RT (dose-reduced combination or single-agent chemotherapy) is deemed appropriate, or nonhigh risk (CTRS <10), for whom ST is deemed appropriate for toxicity. The primary objective was to estimate the agreement in chemotherapy choice (ST vs. RT) between the treating physician and the CTRS using a ? statistic. RESULTS:Fifty-eight patients (median age, 71 years) were enrolled. Thirty-eight patients received ST (21 had CTRS <10, and 17 had CTRS ?10), and 20 patients received RT (12 had CTRS ?10, and 8 had CTRS <10), with minimal agreement in chemotherapy choice (??=?0.14; 95% CI, -0.10 to 0.38). Grade 3-4 toxicity and hospitalization occurred in 60% and 27% of 55 patients with follow-up data, respectively. Among patients receiving ST, patients with CTRS ?10 had a higher incidence of toxicity (88% vs. 40%, p?=?.006) and hospitalization (50% vs. 15%, p?=?.03) than those with CTRS <10. CONCLUSION:Older patients with cancer with a high CTRS who receive combination chemotherapy have an exceedingly high rate of severe toxicity and hospitalization. IMPLICATIONS FOR PRACTICE:The potential utility of the chemotherapy toxicity risk score (CTRS) in old adults with advanced solid tumors receiving first-line chemotherapy was assessed. Little agreement was found between chemotherapy treatment decisions based on the clinical impression versus what was recommended based on the CTRS. Among patients treated with standard-dose combination chemotherapy, patients with CTRS ?10 had a very high incidence of grade 3-4 toxicities and hospitalization, which was significantly greater than that of patients with a low CTRS (<10). These findings suggest that the addition of CTRS to the clinical impression has a potential to improve treatment decisions.

Project description:ImportanceFinancial toxicity (FT), unintended and unanticipated financial burden experienced by cancer patients undergoing cancer care, is associated with negative consequences and increased risk of mortality. Older patients (≥70 years) with cancer are at risk for FT, yet data are limited on FT and whether oncologists discuss FT with their patients.ObjectiveTo examine the prevalence of FT in older adults with advanced cancer, its association with health-related quality of life (HRQoL), and cost conversations between oncologists and patients.Design, setting, and participantsThis cross-sectional secondary analysis was performed on baseline data from the Improving Communication in Older Cancer Patients and Their Caregivers study, a cluster randomized trial from 31 community oncology practices across the US that was conducted from October 29, 2014, to April 28, 2017. Participants included 536 patients with advanced cancer who answered 3 questions regarding financial toxicity. Data were analyzed from September 1, 2019, to May 1, 2020.ExposureOlder patients undergoing cancer care treatments.Main outcomes and measuresThe main outcome looked at FT and its association with HRQoL. Three questions were used to identify patients 70 years or older experiencing FT. Multivariable linear regression models were used to assess the independent associations of FT with HRQoL. A single audio-recorded clinic transcript was analyzed within 4 weeks of enrollment for patients with FT. The framework method was used to identify frequency and themes related to cost conversations.ResultsThis study evaluated 536 patients 70 years or older with advanced cancer. Ninety-eight patients (18.3%) reported FT; mean (SD) age was 76.4 (5.4) years; 59 (60.2%) were female, 14 (14.3%) were Black/African American, 91 (92.9%) were not employed, and 29 (29.6%) had Medicare as their sole insurance coverage. On multivariate regression analyses, FT was associated with higher levels of depression (β = 0.81; 95% CI, 0.15-1.48), anxiety (β = 1.67; 95% CI, 0.74-2.61), and distress (β = 0.73; 95% CI, 0.08-1.39) and lower HRQoL (β = -5.30; 95% CI, -8.92 to -1.69). Among those who reported FT, 49% had a conversation with their health care professional about costs. Most conversations (79%) were initiated by oncologists or patients. Four themes were generated from cost conversations: statements regarding cost of care, ability to afford medical prescriptions, indirect consequences associated with inability to work and provide for family, and cost burden in nontreatment domains.Conclusions and relevanceIn this study, among older adults with advanced cancer, FT is associated with worse HRQoL. Almost half of conversations among patients reporting FT demonstrated costs are being actively discussed. Resources and interventions are needed to manage FT.
