Outpatient Embedded Palliative Care for Patients with Advanced Thoracic Malignancy: A Retrospective Cohort Study

Although cancer care is often contextualized in terms of survival, there are other important cancer care outcomes, such as quality of life and cost of care. The ASCO Value Framework assesses the value of cancer therapies not only in terms of survival but also with consideration of quality of life and financial cost. Early palliative care for patients with advanced cancer is associated with improved quality of life, mood, symptoms, and overall survival for patients, as well as cost savings. While palliative care has been shown to have numerous benefits, the impact of real-world implementation of outpatient embedded palliative care on value-based metrics is not fully understood. We sought to describe the association between outpatient embedded palliative care in a multidisciplinary thoracic oncology clinic and inpatient value-based metrics. We performed a retrospective cohort study of 215 patients being treated for advanced thoracic malignancies with non-curative intent. We evaluated the association between outpatient embedded palliative care and inpatient clinical outcomes including emergency room visits, hospitalizations, intensive care unit admissions, hospital charges, as well as hospital quality metrics including 30-day readmissions, admissions within 30 days of death, inpatient mortality, and inpatient hospital charges. Outpatient embedded palliative care was associated with lower hospital charges per day (USD 3807 vs. USD 4695, p = 0.024). Furthermore, patients who received outpatient embedded palliative care had lower hospital admissions within 30 days of death (O.R. 0.45; 95% CI 0.29, 0.68; p < 0.001) and a lower inpatient mortality rate (IRR 0.67; 95% CI 0.48, 0.95; p = 0.024). Our study further supports that outpatient palliative care is a high-value intervention and alternative models of palliative care, including one embedded into a multidisciplinary thoracic oncology clinic, is associated with improved value-based metrics.

An Oncology Urgent Care Clinic for the Management of Immune-Related Adverse Events: A Descriptive Analysis

Introduction: With the increasing use of immune checkpoint inhibitors (ICI) for cancer, there is a growing burden on the healthcare system to provide care for the toxicities associated with these agents. Herein, we aim to identify and describe the distribution of encounters seen in an urgent care setting for immune-related adverse events (irAEs) and the clinical outcomes from irAE management. Methods: Patient demographics, disease characteristics, and treatment data were collected retrospectively from encounters at an oncology Urgent Care Clinic (UCC) from a single tertiary center for upper aerodigestive malignancies from 1 July 2018 to 30 June 2019. Data were summarized using descriptive statistics with odds ratios for associations between patient features and hospitalization after UCC evaluation. Results: We identified 494 encounters from 289 individual patients over the study period. A history of ICI therapy was noted in 34% (n = 170/494) of encounters and 29 encounters (29/170, 17%) were confirmed and treated as irAEs. For those treated for irAEs, the majority (n = 19/29; 66%) were discharged home. Having an irAE was associated with an increased risk of hospitalization compared to non-irAEs (OR 5.66; 95% CI 2.15−14.89; p < 0.001). Conclusion: In this single institution experience, the majority of UCC encounters for confirmed irAEs were safely managed within the UCC. In ICI-treated patients, having an irAE was associated with an increased risk of hospitalization versus non-irAEs.

NCCN Guidelines® Insights: Older Adult Oncology, Version 1.2021

The NCCN Guidelines for Older Adult Oncology address specific issues related to the management of cancer in older adults, including screening and comprehensive geriatric assessment (CGA), assessing the risks and benefits of treatment, preventing or decreasing complications from therapy, and managing patients deemed to be at high risk for treatment-related toxicity. CGA is a multidisciplinary, in-depth evaluation that assesses the objective health of the older adult while evaluating multiple domains, which may affect cancer prognosis and treatment choices. These NCCN Guidelines Insights focus on recent updates to the NCCN Guidelines providing specific practical framework for the use of CGA when evaluating older adults with cancer.

A trainee-led quality improvement project to improve rates of palliative care utilization in patients with advanced cancer

51

Background: ASCO guidelines recommend palliative care (PC) referral for patients with advanced or metastatic cancer. Despite this, implementation has considerable hurdles. 1st year oncology fellows at our institution identified low rates of palliative care in their longitudinal clinic as an avenue for improvement. Methods: A Fellow-led multidisciplinary team aimed to increase palliative care utilization for patients with advanced cancer followed in first-year fellows’ clinic from baseline 11.5% (5/43 patients, Jul-Dec, '18) to 30% over a 4-mo period. Utilization was defined as evaluation in the outpatient palliative care clinic hosted in the cancer center. The team identified several barriers to referral: orders difficult to find in EMR, multiple consulting mechanisms (EMR, by phone, in person), EMR request not activating formal consult, no centralized scheduler to contact/confirm appointment, and poor awareness of team structure. PDSA cycles were implemented based on identified opportunities. Data were obtained from the EMR. Results: The PDSA cycle included focus groups with stakeholders, standardizing referral process via single order set, identifying a single scheduler with bidirectional communication, and dissemination of process changes. The PDSA was implemented Jan-Apr '19. Rates of palliative care use increased from 11.5% pre-intervention to 43% (27/62 patients) post-intervention. In addition, median time to evaluation in palliative care clinic after placing a consult improved from 23 days (range, 10-60 days) to 12 days (range, 6-19 days). Conclusions: A multidisciplinary approach and classic QI methodology improved palliative care use for patients with advanced cancer. The pilot succeeded given the small number of fellows, buy-in from stakeholders, and institutional support of efforts. Straightforward EMR interventions and ancillary staff use are effective in addressing under referrals.

A phase II study of GVAX colon vaccine with cyclophosphamide and pembrolizumab in patients with mismatch repair–proficient (MMR-p) advanced colorectal cancer

563

Background: Mismatch repair proficient (MMRp) colorectal cancer (CRC) is refractory to single-agent programmed cell death protein 1 (PD1) inhibitors. Cancer vaccines may prime the tumor microenvironment for anti-PD1 therapy. Colon GVAX is an allogeneic, whole-cell, GM-CSF-secreting vaccine that induces T-cell immunity against tumor-associated antigens. GVAX has previously been studied in combination with low-dose cyclophosphamide (Cy) to inhibit regulatory T cells. Methods: We conducted an open label, single-arm, phase 2 study of GVAX/Cy in combination with the PD1 inhibitor pembrolizumab in patients with MMRp CRC who had received at least two prior lines of therapy in the metastatic setting. Patients received pembrolizumab plus Cy on day 1, GVAX on day 2, of a 21 day cycle through 4 cycles, and were then continued on a maintenance regimen of pembolizumab every 3 weeks with cy/GVAX given every 12 weeks. Results: Seventeen patients were enrolled. There were no objective responses, and the disease control rate was 18% by RECIST and 29% by irRC. The median progression free survival was 2.7 months and the median overall survival was 7.0 months. Biochemical responses (≥30% decline in CEA) were observed in 7/17 (41%) of patients. Two patients (12%) had grade 3/4 adverse events that were attributed to study therapy. To test the hypothesis that the induction of a humoral response against CEA protein had resulted in the observed biochemical responses, we measured patient titers of anti-CEA antibodies. Anti-CEA antibody titers increased 13 of 13 patients (100%) with available paired pre- and on-treatment research blood samples, but the change in anti-CEA antibody titers were similar among CEA responders and non-responders. Multiplex immunohistochemistry performed on pre- and post- biopsy specimens will be reported at the conference. Conclusions: GVAX/Cy plus pembrolizumab is well tolerated in advanced MMRp CRC and resulted in CEA responses but not radiographic responses. PFS and OS compare favorably to historical controls in this small cohort. CEA responses were not observed with PD1 monotherapy in MMRp CRC, suggesting GVAX can modulate the antitumor immune response. Clinical trial information: NCT02981524.

Fatigability and endurance performance in cancer survivors: Analyses from the Baltimore Longitudinal Study of Aging

BACKGROUND

Fatigue is prevalent and distressing among cancer survivors, but its subjective nature makes it difficult to identify. Fatigability, defined as task-specific fatigue, and endurance performance may be useful supplemental measures of functional status in cancer survivors.

METHODS

Fatigability, endurance performance, and cancer history were assessed every 2 years in Baltimore Longitudinal Study of Aging participants between 2007 and 2015. Fatigability was defined according to the Borg rating of perceived exertion scale after a 5-minute, slow treadmill walk; and endurance performance was calculated according to the ability and time to complete a fast-paced, 400-meter walk. The association between cancer history, fatigability, and endurance performance was evaluated using longitudinal analyses adjusted for age, sex, body mass index, and comorbidities.

RESULTS

Of 1665 participants, 334 (20%) reported a history of cancer. A combination of older age (>65 years) and a history of cancer was associated with 3.8 and 8.6 greater odds of high perceived fatigability and poor endurance, respectively (P < .01). Older adults with and without a history of cancer walked 42 and 23 seconds slower than younger adults without a history of cancer, respectively (P < .01). The median times to the development of high fatigability and poor endurance were shorter among those who had a history of cancer compared with those who had no history of cancer (P < .01).

CONCLUSIONS

The current findings suggest that a history of cancer is associated with fatigability and poor endurance and that this effect is significantly greater in older adults. Evaluating the effects of cancer and age on fatigability may illuminate potential pathways and targets for future interventions. Cancer 2018;124:1279-87. © 2018 American Cancer Society.

Team Leadership and Cancer End-of-Life Decision Making

End-of-life decision making in cancer can be a complicated process. Patients and families encounter multiple providers throughout their cancer care. When the efforts of these providers are not well coordinated in teams, opportunities for high-quality, longitudinal goals of care discussions can be missed. This article reviews the case of a 55-year-old man with lung cancer, illustrating the barriers and missed opportunities for end-of-life decision making in his care through the lens of team leadership, a key principle in the science of teams. The challenges demonstrated in this case reflect the importance of the four functions of team leadership: information search and structuring, information use in problem solving, managing personnel resources, and managing material resources. Engaging in shared leadership of these four functions can help care providers improve their interactions with patients and families concerning end-of-life care decision making. This shared leadership can also produce a cohesive care plan that benefits from the expertise of the range of available providers while reflecting patient needs and preferences. Clinicians and researchers should consider the roles of team leadership functions and shared leadership in improving patient care when developing and studying models of cancer care delivery.

Engaging patients and stakeholders in the process of designing a clinical trial and patient education platform

63

Background: Patient engagement during the initiation, development, and implementation of a study has been shown to improve the ethical nature of research and the appropriateness of treatment methods, and insights into how best to partner with patients are needed. We describe our patient engagement experience in developing a clinical trial for non-metastatic pancreatic cancer (PCA). Methods: A team of patient research partners (PRPs) was consulted to design a multi-institutional study to evaluate the efficacy of chemotherapy, stereotactic body radiation therapy, and early palliative care (EPC) in patients with PCA who are typically ineligible for clinical trials due to advanced age, poor performance status, or preexisting comorbidities. PRPs included patients, caregivers, clinical researchers, patient advocacy organizations, and pharmaceutical companies. A 22-item initial survey on personal interests and a 5-item follow-up survey on study design were anonymously completed after two in-person meetings. Results: Of 15 PRPs involved, 9 completed the initial survey and 10 completed the follow-up survey. PRPs were most interested in improving quality of life (QOL, 89%), care coordination (78%), symptom management (67%), stress/anxiety (56%), and survival (56%). Confidence in the care team, hope, QOL, education and understanding, dignity, and pain management were reported to be the most important factors throughout the cancer experience. The majority (89%) requested that study participants have access to the study protocol and research publications supporting the study design. Because all PRPs suggested that a personal website be used to provide information to study participants and to disseminate the results of the study, an online patient education platform was adopted and customized for patients (and caregivers). Furthermore, integration of EPC into the treatment regimen was unanimously endorsed. Conclusions: Engaging PRPs in the process of designing a clinical trial for PCA appears to be feasible and valuable in identifying the study objectives most important to patients. PRPs conveyed that maintaining a good QOL is essential, and adoption of EPC in these patients should be considered.

Assessing cognitive function and capacity in older adults with cancer

The number of older individuals with cancer is increasing exponentially, mandating that oncologists contemplate more comprehensive and multidisciplinary approaches to treatment of this cohort. Recruitment of assessment instruments validated in older patients can be invaluable for guiding treatment and decision-making by both patients and providers, and can arguably contribute to improving outcomes and health-related quality of life. The Comprehensive Geriatric Assessment is one such validated instrument that can be used by oncologists to assess patient readiness and appropriateness for prescribed cancer therapy. As a multidisciplinary diagnostic and treatment process, it comprises functional status, cognitive status, social support, and advance care preferences, and is an ideal instrument for evaluating complex older individuals. It is well established that many older individuals with cancer travel with multiple comorbid illnesses, including cognitive impairment, and when presented with a cancer diagnosis struggle to choose from multiple treatment options. In addition to the complete medical history, the ability of patients to decide on a course of therapy in concert with their oncologist is critically important. Alternatively, many oncologists are conflicted as to whether true informed consent for treatment can be obtained from many older patients. Having a roadmap to decision-making capacity is therefore an inescapable imperative in geriatric oncology, because careful attention must be directed at identifying older patients with cancer who might benefit from these assessments and the individualized treatment plans that emerge.

Chemotherapy-induced diarrhea in older patients with colorectal cancer receiving fluoropyrimidines: A retrospective review

e14647

Background: Chemotherapy-induced diarrhea (CID) is a common treatment-limiting toxicity of regimens used for colorectal cancer (CRC). Fluoropyrimidines, the backbone of CRC regimens, are associated with diarrhea, but the frequency and severity in older patients are less known due to under-representation of older patients in CRC trials. As life expectancy increases, the prevalence of older CRC patients will increase. We aimed to evaluate if older patients are vulnerable to CID. Methods: We retrospectively studied patients >70 years old who received fluoropyrimidines based therapy for stages II-IV CRC at Johns Hopkins and Bayview Medical Center from 1996-2007. Patient demographics and cancer-specific data were retrieved. Diarrhea was graded per National Cancer Institute Clinical Toxicity Criteria. Results: We included 150 patients > 70 years old. Median age was 75 (range 70-87). 65 (43%) were 70-74 years old, 52 (35%) were 75-79 years and 33 (22%) > 80. Diarrhea occurred in 48% (n=72) of patients. Presence of diarrhea was not significantly associated with increasing age (70-74, 75-79 or >80 years), gender, ECOG performance, number of comorbidities or medications. Severe grade 3-4 diarrhea occurred in 16% (n=24) and was associated with advanced stage (p=0.04). CID (all grades) was more common in cycle 1 than subsequent cycles (p=0.002). Conclusions: Fluoropyrimidines based therapy was tolerated in older patients with CRC. Incidence of CID was not associated with increasing age, gender, performance, comorbidities or polypharmacy. Severe diarrhea occurs in advanced stage and early during therapy. Larger prospective studies are needed to definitively evaluate the impact of age on CID.
