Polypharmacy in older adults with cancer undergoing radiotherapy: A review.

Polypharmacy is characterized by the simultaneous use of multiple medications, including prescription drugs, over-the-counter drugs, and nutritional supplements. Polypharmacy is known to increase the risk of adverse drugs reactions, drug-drug interactions, and medication errors, and to negatively impact quality of life. The prevalence of polypharmacy varies by population, but has been reported to exceed 90% among older adults with cancer. Polypharmacy may be exacerbated among older adults with cancer receiving radiation therapy due to the resulting acute or chronic side effects that need to be managed with additional medications. The medications prescribed to manage radiation-related side effects increase the risk of adverse drug events, as do changes in nutritional status related to the secondary side effects of radiation treatment. Side effects from treatment may result in the need for breaks in cancer therapy or treatment delays, which ultimately can lead to worse oncologic outcomes. Few studies have examined polypharmacy in the context of older adults undergoing radiation therapy. We sought to review the literature pertaining to polypharmacy among older adults with cancer and discuss implications specifically for those individuals undergoing radiation therapy. This paper presents a narrative review of studies published in the past decade that provided detailed information on polypharmacy in older adults undergoing radiation therapy for cancer. The review elucidated good practices to avoid adverse drug events from polypharmacy, but more studies are warranted to develop standard guidelines.

Toxicity and survival outcomes in older adults receiving concurrent or sequential chemoradiation for stage III non-small cell lung cancer in Alliance trials (Alliance A151812).

INTRODUCTION: Optimal treatment for older adults with stage III non-small cell lung cancer (NSCLC) remains unclear. Here we hypothesized that sequential chemoradiation therapy (sCRT) is better tolerated than concurrent (cCRT) but confers acceptable efficacy. We evaluated these strategies in older adults utilizing Alliance for Clinical Trials in Oncology data. MATERIALS AND METHODS: Pooled analyses from 6 first-line stage III NSCLC CRT trials (Cancer and Leukemia Group B 8433, 8831, 9130, 30106, 30407, 39801) were used to compare toxicity and survival outcomes with cCRT versus sCRT in patients age ≥ 65 years. Grade 3-5 adverse events (AEs), progression-free and overall survival (PFS; OS) are reported with adjustment for covariates. RESULTS: Four hundred older adults, of whom 106 (26.5%) had received sCRT and 294 (73.5%) had received cCRT, comprised the cohorts. Virtually all had an Eastern Cooperative Oncology Group performance status (ECOG PS) 0-1 (99%). More grade 3-5 AEs were observed at any time-point with cCRT than sCRT (94.2% versus 86.8%; 95% confidence interval for difference in proportions, 1.3%, 15.5%) and this finding remained after adjusting for length of study treatment (P = 0.018). Comparable PFS and OS were observed with sCRT versus cCRT (median: 8.0 versus 9.2 months; median: 11.9 versus 13.4 months, respectively) even after adjustment for age, sex, ECOG PS, body mass index, pretreatment weight loss, stage, and cisplatin-based therapy (P = 0.604 and P = 0.906, respectively). DISCUSSION: These data show that sCRT was associated with less toxicity than cCRT with no associated statistically significant decrease in efficacy outcomes and that sCRT merits further study in this population.

How Is Geriatric Assessment Used in Clinical Practice for Older Adults With Cancer? A Survey of Cancer Providers by the American Society of Clinical Oncology.

PURPOSE: For patients with cancer who are older than 65 years, the 2018 ASCO Guideline recommends geriatric assessment (GA) be performed. However, there are limited data on providers' practices using GA. Therefore, ASCO's Geriatric Oncology Task Force conducted a survey of providers to assess practice patterns and barriers to GA. METHODS: Cancer providers treating adult patients including those ≥ 65 years completed an online survey. Questions included those asking about awareness of ASCO's Geriatric Oncology Guideline (2018), use of validated GA tools, and perceived barriers to using GA. Descriptive statistics and statistical comparisons between those aware of the Guideline and those who were not were conducted. Statistical significance was set at P < .05. RESULTS: Participants (N = 1,277) responded between April 5 and June 5, 2019. Approximately half (53%) reported awareness of the Guideline. The most frequently used GA tools, among those aware of the Guideline and those who were not, assessed functional status (69% v 50%; P < .001) and falls (62% v 45%; P < .001). Remaining tools were used < 50% of the time, including tools assessing weight loss, comorbidities, cognition, life expectancy, chemotherapy toxicity, mood, and noncancer mortality risk. GA use was two to four times higher among those who are aware of the Guideline. The most frequent barriers for those who reported being Guideline aware were lack of resources, specifically time (81.7%) and staff (77.0%). In comparison, those who were unaware of the Guideline most often reported the following barriers: lack of knowledge or training (78.4%), lack of awareness about tools (75.2%), and uncertainty about use of tools (75.0%). CONCLUSION: Among providers caring for older adults, 52% were aware of the ASCO Guideline. Some domains were assessed frequently (eg, function, falls), whereas other domains were assessed rarely (eg, mood, cognition). Guideline awareness was associated with two to four times increased use of GA and differing perceived barriers. Interventions facilitating Guideline-consistent implementation will require various strategies to change behavior.

Identifying Geriatric Oncology Competencies for Medical Oncology Trainees: A Modified Delphi Consensus Study.

BACKGROUND: Most oncology trainees are not taught about the needs of older patients, who make up the majority of patients with cancer. Training of health care providers is critical to improve the care of older adults with cancer. There is no consensus about which geriatric oncology (GO) competencies are important for medical oncology trainees. Our objective was to identify GO competencies medical oncology trainees should acquire during training. MATERIALS AND METHODS: A modified Delphi consensus of experts in oncology medical education and GO was conducted. Experts categorized at what training stage proposed competencies should be attained: internal medicine, oncology, or GO training. Consensus was obtained if two thirds of experts agreed on the training stage at which the competency should be attained. RESULTS: A total of 78 potential competencies were identified, of which 35 (44.9%) proposed competencies were felt to be appropriate to be acquired during oncology training. The majority of the identified competencies pertained to prescribing of systemic therapy (n = 12) and psychosocial and supportive care (n = 13). No competencies related to geriatric assessment were identified for acquisition during oncology training. CONCLUSION: Experts in oncology education and geriatric oncology agreed upon a set of GO competencies appropriate for oncology trainees. These results provide the foundation for developing a GO curriculum for medical oncology trainees and will hopefully lead to better care of older adults with cancer. IMPLICATIONS FOR PRACTICE: The aging population will drive the projected rise in cancer incidence. Although aging patients make up the majority of patients diagnosed with cancer, oncologists rarely receive training on how to care for them. Training of health care providers is critical to improving the care of older adults with cancer. The results of this study will help form the foundation of developing a geriatric oncology curriculum for medical oncology trainees.

Risk of brain metastases in T1-3N0 NSCLC: a population-based analysis.

AIM: Several consensus guidelines recommend against routine brain imaging at diagnosis of T1-3N0 non-small cell lung cancer (NSCLC). METHODS: From the Surveillance, Epidemiology and End Results registry, patients with pathologically confirmed T1-3N0 NSCLC were identified. Risks of brain metastases at time of initial diagnosis were analyzed. RESULTS: Patients selected to not undergo primary NSCLC resection had approximately tenfold greater incidence of brain metastases versus those who did. Younger age, adenocarcinoma histology, higher tumor stage and higher histologic grade were all significantly (p < 0.0001) associated with greater likelihood of presenting with brain metastases. CONCLUSION: Given the morbidity and mortality of brain metastases, routine brain screening after NSCLC diagnosis (particularly adenocarcinoma) may be justifiable, though more refined cost-benefit analyses are warranted.

Immune checkpoint inhibitors in older adults with melanoma or cutaneous malignancies: The Wilmot Cancer Institute experience.

OBJECTIVES: The purpose of this study was to explore the associations between age and frailty with immune-related adverse events (irAEs) among patients with cutaneous malignancies receiving immune checkpoint inhibitor (ICI) therapy. METHODS: A retrospective review of all patients receiving ipilimumab, nivolumab, or pembrolizumab for treatment of cutaneous malignancies at the Wilmot Cancer Institute between 1 Jan 2011 and 3 Apr 2017. RESULTS: A total of 120 patients (age <70 N = 68, age ≥70 N = 52; range, 26-93) were identified. 44.1%[95%CI:32-57%] of patients age <70 and 31.4%[95%CI:19-46%] of patients age ≥70 experienced ≥1 irAE on 1st line ICI therapy (P = 0.158). A total of 3 adults died of irAEs (2 age ≥70; 1 age <70). Patients ≥70 were more frequently treated with anti-PD-1 monotherapy than dual checkpoint blockade or ipilimumab (P < 0.01) in the first line setting. Among patients on first line anti-PD-1 monotherapy for cutaneous melanoma, 21 were age <70 and 20 were age ≥70, with similar observed rates of irAEs (52.4%[95%CI 29.8-74.3] and 63.2%[95%CI 38.4-83.7]). Indirect frailty markers in patients age ≥70 such as having fallen in the prior six months, ECOG PS ≥2 or Charlson comorbidity scores ≥11 experienced similar rates of response and toxicity. Among 9 patients with a PS = 3, 8 died, 6 due to progressive disease. No deaths due to irAEs occurred in this frail subgroup. CONCLUSION: Anti-PD-1 monotherapy for older adults with cutaneous malignancies have similar response and irAE rates when compared to those of younger patients. Deaths from disease progression were more frequent than those from toxicity in both age subgroups.

Educating healthcare providers in geriatric oncology - A call to accelerate progress through identifying the gaps in knowledge.

The majority of patients with cancer are over the age of 65. This patient population often has unique care needs. Thus, clinicians require additional competencies and skills to care for this population. Most clinicians, however, receive little to no training in geriatrics. There has been increasing recognition of the importance of learning about geriatric oncology. However, teaching of geriatric oncology principles is not standard or widespread. Here we highlight educational work and scholarship accomplished thus far in the field of geriatric oncology and identify gaps in knowledge that need to be addressed in order to help accelerate the development, implementation, integration, and dissemination of geriatric oncology curricula. These, in turn, will hopefully help improve the knowledge and skills of clinicians caring for older adults with cancer globally.

Immune Checkpoint Inhibitors in Real-World Treatment of Older Adults with Non-Small Cell Lung Cancer.

OBJECTIVE: To evaluate the efficacy and toxicity of immune checkpoint inhibitors (ICIs) in older patients with advanced non-small cell lung cancer (NSCLC) seen in routine clinical practice. DESIGN: Retrospective study. SETTING: Single academic institution and its affiliated centers. PARTICIPANTS: Patients 70 years or older with advanced-stage NSCLC seen between April 1, 2015, and April 1, 2017, and treated with ICIs. MEASUREMENTS: Efficacy data included overall survival (OS) and time to treatment failure (TTF), stratified by age, comorbidities (Charlson Comorbidity Index [CCI]), and Eastern Cooperative Oncology Group Performance Status (ECOG PS), and estimated using the Kaplan-Meier method and log-rank test. Toxicity data included immune-related adverse events (irAEs), need for glucocorticoids, and hospitalization. The associations of toxicity with age, CCI, and ECOG PS were evaluated using the exact χ2 test or Fisher exact test. RESULTS: We included 75 patients (median age: 74 y; range, 70-92 y); 53% had a CCI of 3 or higher; 49% had ECOG PS of 2 or higher. Median OS for the whole cohort was 8.2 months (ECOG PS 0-1 vs ≥2: 13.7 vs 3.8 mo; p < .01). Median TTF was 4.2 months (ECOG PS 0-1 vs ≥2: 5.6 vs 2.0 mo; p = .02). Overall, 37% of patients experienced irAE of any grade (a total of 37 events); 8% were grade 3 or higher (no ICI-related deaths). Of those who discontinued ICIs (N = 64), 15% were due to irAEs. Of those who experienced irAEs, 64% required glucocorticoids. Hospitalizations during ICI treatment occurred in 72%. Toxicity generally did not differ by age, CCI, or ECOG PS. CONCLUSIONS: Outcomes in our cohort were driven by ECOG PS rather than chronological age or comorbidities. The relatively high rates of ICI discontinuation, use of glucocorticoids, and hospitalization during ICI treatment in our study highlight the vulnerability of older adults with advanced NSCLC even in the immunotherapy era.

Characterizing cancer cachexia in the geriatric oncology population.

OBJECTIVES: Cancer cachexia, characterized by weight loss and sarcopenia, leads to a decline in physical function and is associated with poorer survival. Cancer cachexia remains poorly described in older adults with cancer. This study aims to characterize cancer cachexia in older adults by assessing its prevalence utilizing standard definitions and evaluating associations with components of the geriatric assessment (GA) and survival. MATERIALS AND METHODS: Patients with cancer older than 65 years of age who underwent a GA and had baseline CT imaging were eligible in this cross-sectional study. Cancer cachexia was defined by the international consensus definition reported in 2011. Sarcopenia was measured using cross-sectional imaging and utilizing sex-specific cut-offs. Associations between cachexia, sarcopenia, and weight loss with survival and GA domains were explored. RESULTS: Mean age of 100 subjects was 79.9 years (66-95) and 65% met criteria for cancer cachexia. Cachexia was associated with impairment in instrumental activities of daily living (IADL) (p = .017); no significant association was found between sarcopenia or weight loss and IADL impairment. Cachexia was significantly associated with poorer survival (median 1.0 vs 2.1 years, p = .011). CONCLUSIONS: Cancer cachexia as defined by the international consensus definition is prevalent in older adults with cancer and is associated with functional impairment and decreased survival. Larger prospective studies are needed to further describe cancer cachexia in this population.

Management of Localized Breast Angiosarcoma by North American Radiation and Medical Oncologists.

INTRODUCTION: Primary breast angiosarcoma is a rare malignancy with no clinical trials to guide management. The current use of surgery, chemotherapy, and radiotherapy among North American oncologists is unknown. PATIENTS AND METHODS: An institutional review board-approved anonymous electronic survey was distributed to 9660 practicing North American radiation and medical oncologists. Questions pertained to treatment recommendations for localized nonmetastatic primary breast angiosarcoma, as well as knowledge/use of ß-blockers in angiosarcoma. The Fisher exact test was used to compare responses of medical and radiation oncologists. RESULTS: Surgery was recommended by 95% of all respondents. Chemotherapy was recommended by over half of medical and radiation oncologists. Radiotherapy was recommended by 92% of radiation and 56% of medical oncologists. The most common treatment recommendation was a trimodal treatment, with up-front surgery followed by adjuvant chemotherapy, then by adjuvant radiotherapy. Twenty-two percent of respondents were aware of clinical data pertaining to the use of ß-blockers in management of angiosarcoma, and among these respondents 69% were comfortable incorporating this treatment into standard practice. CONCLUSION: Trimodal management of primary localized breast angiosarcoma is supported by North American radiation and medical oncologists, with the majority recommending up-front surgery followed by adjuvant chemotherapy and radiation. The recently published reports of successful use of ß-blockers are not yet known among North American clinicians, but there is a great enthusiasm to incorporate these commonly prescribed medications into standard practice. These findings may greatly influence the standard of care for breast angiosarcoma treatment, particularly given the absence of Level I-supported evidence.

Factors associated with falls in older adults with cancer: a validated model from the Cancer and Aging Research Group.

BACKGROUND: Falls in older adults with cancer are common, yet factors associated with fall-risk are not well-defined and may differ from the general geriatric population. This study aims to develop and validate a model of factors associated with prior falls among older adults with cancer. METHODS: In this cross-sectional secondary analysis, two cohorts of patients aged ≥ 65 with cancer were examined to develop and validate a model of factors associated with falls in the prior 6 months. Potential independent variables, including demographic and laboratory data and a geriatric assessment (encompassing comorbidities, functional status, physical performance, medications, and psychosocial status), were identified. A multivariate model was developed in the derivation cohort using an exhaustive modeling approach. The model selected for validation offered a low Akaike Information Criteria value and included dichotomized variables for ease of clinical use. This model was then applied in the validation cohort. RESULTS: The development cohort (N = 498) had a mean age of 73 (range 65-91). Nearly one-fifth (18.2%) reported a fall in the prior 6 months. The selected model comprised nine variables involving functional status, objective physical performance, depression, medications, and renal function. The AUC of the model was 0.72 (95% confidence intervals 0.65-0.78). In the validation cohort (N = 250), the prevalence of prior falls was 23.6%. The AUC of the model in the validation cohort was 0.62 (95% confidence intervals 0.51-0.71). CONCLUSION: In this study, we developed and validated a model of factors associated with prior falls in older adults with cancer. Future study is needed to examine the utility of such a model in prospectively predicting incident falls.

Interdisciplinary Oncology Education: a National Survey of Trainees and Program Directors in the United States.

Oncologists must have a strong understanding of collaborating specialties in order to deliver optimal cancer care. The objective of this study was to quantify current interdisciplinary oncology education among oncology training programs across the USA, identify effective teaching modalities, and assess communication skills training. Web-based surveys were sent to oncology trainees and program directors (PDs) across the USA on April 1, 2013 and October 8, 2013, respectively. Question responses were Yes/No, five-point Likert scales (1 = not at all, 2 = somewhat, 3 = moderately, 4 = quite, 5 = extremely), or free response. Respondents included the following (trainees/PDs): 254/55 medical oncology, 160/42 surgical oncology, 102/24 radiation oncology, and 41/20 hospice and palliative medicine (HPM). Trainees consistently reported lower rates of interdisciplinary education for each specialty compared with PDs as follows: medical oncology 57 vs. 77% (p < 0.01), surgical oncology 30 vs. 44% (p < 0.01), radiation oncology 70 vs. 89% (p < 0.01), geriatric oncology 19 vs. 30% (p < 0.01), and HPM 55 vs. 74% (p < 0.01). The predominant teaching method used (lectures vs. rotations vs. tumor board attendance vs. workshop vs. other) varied according to which discipline was being taught. The usefulness of each teaching method was rated statistically different by trainees for learning about select disciplines. Furthermore, statistically significant differences were found between PDs and trainees for the perceived usefulness of several teaching modalities. This study highlights a deficiency of interdisciplinary education among oncology training programs in the USA. Efforts to increase interdisciplinary education opportunities during training may ultimately translate into improved collaboration and quality of cancer care.

Geriatrics fellowship training and the role of geriatricians in older adult cancer care: A survey of geriatrics fellowship directors.

The number of older adults with cancer is growing, necessitating more collaborative training in geriatric principles and cancer care. The authors administered a web-based survey to U.S. geriatrics program directors (PDs) addressing cancer-specific training and perspectives on optimal training content and roles for geriatricians in cancer care. Of 140 PDs contacted, 67 (48%) responded. Topics considered very important in training included cancer screening (79%) and cancer-related pain management (70%). Respondents strongly agreed that some of the geriatrician's roles in cancer care included assessing functional status (64%) and assessing physical/cognitive function for goals of care (64%). About one half (54%) agreed that having a standardized geriatric oncology curriculum overall was important. The presence of a geriatric oncologist, requiring cancer-based rotations, being affiliated with a cancer center, or being internal versus family medicine-based did not affect this response. Despite this high level of support, cancer-related skills and knowledge warrant better definition and integration into current geriatrics training. This survey establishes potential areas for future educational collaborations between geriatrics and oncology training programs.

Ototoxicity monitoring through the eyes of the treating physician: Perspectives from pulmonology and medical oncology.

OBJECTIVES: Integrating audiological management into the care pathways of clinical specialties that prescribe ototoxic medications for essential, often life-preserving medical care that is critical for early hearing loss identification and remediation. Research shows that successful implementation of a new health service or intervention requires alignment of goals among provider groups, institutional leadership and patients. Thoughtful consideration of the physician's viewpoints about ototoxicity and its implications for treatment planning is, therefore, important for the implementation and enduring success of an ototoxicity monitoring programme (OMP). DESIGN: This discussion paper uses qualitative methods to explore the perspectives of four physicians on OMP provision in their patient populations. STUDY SAMPLE: Three pulmonologists and one oncologist completed the written survey or survey-based interview described in this report. RESULTS: Each physician indicated that (i) ototoxicity is a potential problem for their patients; (ii) monitoring hearing is important to ensure good quality of life among their patients and (iii) treatment modification would be considered if an alternative treatment option were available. The physicians differed in their approaches to ototoxicity monitoring, from routine referrals to audiology, to relying on patient self-referral. CONCLUSION: Physician provider input is needed to optimise monitoring schedules and OMP care coordination with audiology.

Hematology-Oncology Fellows' Training in Geriatrics and Geriatric Oncology: Findings From an American Society of Clinical Oncology-Sponsored National Survey.

PURPOSE: Older adults compose the majority of patients with cancer in the United States; however, it is unclear how well geriatrics or geriatric oncology training is being incorporated into hematology-oncology (hem-onc) fellowships. METHODS: A convenience sample of hem-onc fellows completed a (written or electronic) survey assessing their education, clinical experiences, and perceived proficiency in geriatric oncology during training; knowledge base in geriatric oncology; confidence in managing older adults with cancer; and general attitudes toward geriatric oncology principles. RESULTS: Forty-five percent of respondents (N = 138) were female, 67% were based in the United States, and most (60%) were past their first year of training. Most fellows rated geriatric oncology as important or very important (84%); however, only 25% reported having access to a geriatric oncology clinic and more than one half (53%) reported no lectures in geriatric oncology. Fellows reported fewer educational experiences in geriatric oncology than in nongeriatric oncology. For example, among procedure-based activities, 12% learned how to perform a geriatric assessment but 78% learned how to perform a bone marrow biopsy ( P < .05). Of those completing the knowledge-based items, 41% were able to identify correctly the predictors of chemotherapy toxicity in older adults with cancer. CONCLUSION: Despite the prevalence of cancer in older adults, hem-onc fellows report limited education in or exposure to geriatric oncology. The high value fellows place on geriatric oncology suggests that they would be receptive to additional training in this area.

Improving outcomes in veterans with oropharyngeal squamous cell carcinoma through implementation of a multidisciplinary clinic.

BACKGROUND: Treatment of head and neck cancer is complex, and a multidisciplinary clinic may improve the coordination of care. The value of a head and neck multidisciplinary clinic has not yet been established in oropharyngeal squamous cell carcinoma (SCC). METHODS: A retrospective review was conducted of Veterans Affairs patients with oropharyngeal SCC undergoing concurrent chemoradiation before and after implementation of the head and neck multidisciplinary clinic. RESULTS: Fifty-two patients before and 54 patients after multidisciplinary clinic were included in this study. Age, tobacco use, and p16+ status were similar between groups. With multidisciplinary clinic, time to treatment decreased, and utilization of supportive services, including speech pathology, dentistry, and nutrition increased. The 5-year disease-specific survival rate increased from 63% to 81% (p = .043) after implementation of the multidisciplinary clinic. Multivariate analysis showed that disease stage (p = .016), p16 status (p = .006), and multidisciplinary clinic participation (p = .042) were predictors of disease-specific survival. CONCLUSION: Implementation of a multidisciplinary clinic improved care coordination and disease-specific survival in patients with oropharyngeal SCC. © 2017 Wiley Periodicals, Inc.

Locally advanced head and neck cancer in either the older or the vulnerable adult: Making the case for a team-based, "gero-centric" approach.

Multidisciplinary, team-based care goes hand in hand with geriatric oncology paradigms for caring for older adults with cancer. Team-based care was the central theme for the 2015 SIOG Annual Meeting. Team-based approaches to the evaluation and management of older adults with different cancer types, including head and neck cancer, were presented. This review aims to summarize the salient points of that presentation, including a synthesis of recent multidisciplinary, "gero-centric" research efforts to improve the care for older adults with more advanced stages of head and neck cancer.

Polypharmacy and potentially inappropriate medication use in older adults with cancer undergoing chemotherapy: effect on chemotherapy-related toxicity and hospitalization during treatment.

OBJECTIVES: To evaluate the prevalence of polypharmacy and potentially inappropriate medication (PIM) use and the association between these and chemotherapy-related adverse events in older adults with cancer undergoing chemotherapy. DESIGN: Secondary analysis of prospectively collected data. SETTING: Outpatient oncology clinics in seven academic medical centers. PARTICIPANTS: Adults aged 65 and older with cancer undergoing chemotherapy. MEASUREMENTS: Measures included number of daily medications (polypharmacy); PIM use based on three indices (Beers, Zhan, and Drugs to Avoid in the Elderly criteria), and use of six "high risk" medication classes for adverse drug events (anticoagulants, antiplatelet agents, opioids, insulin, oral hypoglycemics, antiarrhythmics). Using multivariate logistic regression, the relations were evaluated between these criteria and Grade 3 to 5 chemotherapy-related toxicity and between these criteria and hospitalization during chemotherapy. RESULTS: Participants (N=500; mean age 73, 61% Stage IV disease) took a mean of 5±4 daily medications (range 0-23). PIM use was common (up to 29% according to Beers criteria). No association was found between number of daily medications (reference 0-3 medications) and toxicity (4-9 medications, odds ratio (OR)=1.34, 95% confidence interval (CI)=0.92-1.97; ≥10 medications, OR=0.82, 95% CI=0.45-1.49) or hospitalization (≥4 medications, OR=1.34, 95% CI=0.82-2.18, P=.24). There was also no association between PIM use and toxicity (P=.93) or hospitalization (P=.98). No medication class was associated with either outcome. CONCLUSIONS: Polypharmacy and PIM use were common but were not associated with chemotherapy-related toxicity or hospitalization in older adults with cancer.

Perceptions, attitudes, and experiences of hematology/oncology fellows toward incorporating geriatrics in their training.

The aging of the U.S. population continues to highlight emerging issues in providing care generally for older adults and specifically for older adults with cancer. The majority of patients with cancer in the U.S. are currently 65 years of age or older; therefore, training and research in geriatrics and geriatric oncology are viewed to be integral in meeting the needs of this vulnerable population. Yet, the ways to develop and integrate best geriatrics training within the context of hematology/oncology fellowship remain unclear. Toward this end, the current study seeks to evaluate the prior and current geriatric experiences and perspectives of hematology/oncology fellows. To gain insight into these experiences, focus groups of hematology/oncology fellows were conducted. Emergent themes included: 1) perceived lack of formal geriatric oncology didactics among fellows; 2) a considerable amount of variability exists in pre-fellowship geriatric experiences; 3) shared desire to participate in a geriatric oncology-based clinic; 4) differences across training levels in confidence in managing older adults with cancer; and 5) identification of specific criteria on how best to approach older adults with cancer in a particular clinical scenario. The present findings will help guide future studies in evaluating geriatrics among hematology/oncology fellows across institutions. They will also have implications in the development of geriatrics curricula and competencies specific to hematology/oncology training.
