A theoretical explanation for how a nutrition counseling and medically tailored meal delivery program benefitted participants living with lung cancer.

PURPOSE: The purpose of this study was to assess participants' perceptions and experiences while participating in a Food is Medicine medically tailored meal plus intensive nutrition counseling intervention to create a theoretical explanation about how the intervention worked. METHODS: This interpretive qualitative study included the use of semi-structured interviews with active participants in a randomized controlled trial aimed at understanding how a medically tailored meal plus nutrition counseling intervention worked for vulnerable individuals with lung cancer treated at four cancer centers across the USA. During the 8-month long study, participants in the intervention arm were asked to be interviewed, which were recorded, transcribed verbatim, and analyzed using conventional content analysis with principles of grounded theory. RESULTS: Twenty individuals participated. Data analysis resulted in a theoretical explanation of the intervention's mechanism of action. The explanatory process includes three linked and propositional categories leading to patient resilience: engaging in treatment, adjusting to diagnosis, and active coping. The medically tailored meals plus nutrition counseling engaged participants throughout treatment, which helped participants adjust to their diagnosis, leading to active coping through intentional self-care, behavior change, and improved quality of life. CONCLUSIONS: These findings provide evidence that a Food is Medicine intervention may buffer some of the adversity related to the diagnosis of lung cancer and create a pathway for participants to experience post-traumatic growth, develop resilience, and change behaviors to actively cope with lung cancer. Medically tailored meals plus intensive nutrition counseling informed by motivational interviewing supported individuals' adjustment to their diagnosis and resulted in perceived positive behavior change.

The FITNESS study: longitudinal geriatric assessment, treatment toxicity, and biospecimen collection to assess functional disability among older adults with lung cancer.

Introduction: Older adults with chronic disease prioritize functional independence. We aimed to describe the feasibility of capturing functional disability and treatment toxicity among older adults with lung cancer using a longitudinal comprehensive geriatric assessment (CGA) and molecular biomarkers of aging. Methods: This prospective study included adults ≥60 years with any newly diagnosed non-small-cell lung cancer. Participants were recruited from central Ohio (2018-2020). Study assessments included the Cancer and Aging Research Group CGA (CARG-CGA), short physical performance battery (SPPB), and the blessed orientation-memory concentration (BOMC) test at baseline, 3, 6, and 12 months. Activities of daily living (ADLs) and instrumental ADLs (IADLs), quality of life (QoL, PROMIS 10), and treatment toxicity were captured monthly. Stool and blood were collected to characterize the gut microbiome and age-related blood biomarkers. Results: This study enrolled 50 participants with an average age of 71.7 years. Ninety-two percent of participants were Caucasian, 58% were male, and all were non-Hispanic. Most had advanced stage (stage III/IV: 90%; stage I/II: 10%), with adenocarcinoma the predominant histologic subtype (68% vs. 24% squamous). First-line treatments included chemotherapy (44%), immune checkpoint inhibitors (ICIs, 22%), chemotherapy and ICIs (30%), or tyrosine kinase inhibitors (4%). The median baseline CARG toxicity score was 8 (range 2-12). Among patients with treatment-related toxicity (n = 49), 39 (79.6%) cases were mild (grade 1-2), and 10 (20.4%) were moderate to severe (≥ grade 3). Treatment toxicity was greater among those with a CARG score ≥8 (28.0% vs. 13.6%). Higher IADL independence, QoL, and SPPB scores at baseline were positively associated with Candidatus Gastranaerophilales bacterium, Lactobacillus rogosae, and Enterobacteria phage P4. Romboutsia ilealis, Streptococcus, and Lachnoclostridium sp An138 and T cell lag3 and cd8a were associated with worse IADLs, QoL, and SPPB scores at baseline. Discussion: A longitudinal CGA and biomarker collection is feasible among older adults undergoing lung cancer treatment. Gut microbe and T cell gene expression changes correlated with subjective and objective functional status assessments. Future research will test causality in these associations to improve outcomes through novel supportive care interventions to prevent functional disability.

Safety and efficacy outcomes of early cessation of anti-PD1 therapy in patients 80 years or older: A retrospective cohort study.

Older patients have similar immune checkpoint inhibitor efficacy and rates of adverse events as younger patients, but appear to have decreased tolerability, particularly in the oldest patient cohort (>80 years), often leading to early cessation of therapy. We aimed to determine whether early discontinuation impacts efficacy of anti-PD-1 therapy in patients ≥80 years old. In this retrospective, multicenter, international cohort study, we examined 773 patients with 4 tumor types who were at least 80 years old and treated with anti-PD-1 therapy. We determined response rate, overall survival (OS), and progression-free survival (PFS) in patients who discontinued therapy early (<12 months) for reasons other than progression or death. We used descriptive statistics for demographics, response, and toxicity rates. Survival statistics were described using Kaplan Meier curves. Median (range) age at anti-PD-1 initiation was 83.0 (75.8-97.0) years. The cancer types included were melanoma (n = 286), non-small cell lung cancer (NSCLC) (n = 345), urothelial cell carcinoma (UCC) (n = 108), and renal cell carcinoma (RCC) (n = 34). Of these, 102 met the primary endpoint of <12 months to discontinuation for reasons other than death or progression. Median PFS and OS, respectively, for these patients were 34.4 months and 46.6 months for melanoma, 15.8 months and 23.4 months for NSCLC, and 10.4 months and 15.8 months for UCC. This study suggests geriatric patients who have demonstrated therapeutic benefit and discontinued anti-PD-1 therapy at less than 12 months of duration for reasons other than progression may have durable clinical benefit without additional therapy.

Survivorship in Advanced Lung Cancer: Understanding a New Landscape and Opportunities.

People with advanced lung cancer represent a distinct group whose needs remain understudied, especially compared with people diagnosed with limited-stage disease. Fortunately, novel treatments such as tyrosine kinase inhibitors and immune checkpoint inhibitors are leading to significant advances in prognosis and survival, even among those with advanced disease at the time of diagnosis. However, there are known gaps in symptom management, psychosocial and nutritional support, complex care coordination, health behavior coaching, and health care delivery efforts among patients living with advanced lung cancer. Many of these patients would benefit from survivorship and palliative care approaches. In particular, survivorship care may include health care maintenance, treatment of immune-related adverse events and late- or long-term effects, frailty assessment and rehabilitation, and care coordination. Palliative care may be best suited to discuss ongoing symptom management, advanced care planning, and end-of-life considerations, as well as psychosocial well-being. To this end, we share a review of the current status of the palliative and survivorship care infrastructure for patients with advanced lung cancer and provide suggestions across the care continuum for this diverse group of patients and families.

Determining the relationship of p16INK4a and additional molecular markers of aging with clinical frailty in hematologic malignancy.

PURPOSE: Older adults with hematologic malignancies (HM) have unique challenges due to age and fitness. The primary aim of this pilot study was to benchmark the ability of multiple biomarkers of aging (p16, epigenetic clocks, T cell gene expression profiles, and T cell receptor excision circles (TREC) to identify frailty as measured by a clinical impairment index (I2) in patients with HM. METHODS: 70 patients newly diagnosed with HM had peripheral blood T lymphocytes (PBTL) analyzed for p16INK4a expression using the OSU_Senescence Nanostring CodeSet. PBTL epigenetic age was measured using 7 epigenetic clocks, and TREC were quantified by qRT-PCR. A composite clinical impairment index (I2) was generated by combining values from 11 geriatric metrics (Independent Activities of Daily Living (iADL), physical health score, Short Physical Performance Battery (SPPB), Body Mass Index (BMI), Eastern Cooperative Oncology Group (ECOG) performance status, self-reported KPS, Blessed Orientation Memory Concentration (BOMC), polypharmacy, Mental Health Inventory (MHI)-17, Medical Outcomes Study (MOS) subscales). Clinical frailty was defined as a score of 7 or greater on the I2. RESULTS: Age-adjusted p16INK4a was similar in newly diagnosed patients and healthy controls (p > 0.1). PBTL p16INK4a levels correlated positively with the Hannum [r = 0.35, 95% CI (0.09-0.75); p adj. = 0.04] and PhenoAge [r = 0.37, 95% CI (0.11-0.59); p adj. = 0.04] epigenetic clocks. The discrimination ability of the I2 model was calculated using the area under the receiver operating characteristic curve (AUC). After adjusting for chronologic age and disease group, baseline p16INK4a [AUC = 0.76, 95% CI (0.56-0.98); p = 0.01], Hannum [AUC = 0.70, 95% CI (0.54-0.85); p = 0.01], PhenoAge [AUC = 0.71, 95% CI (0.55-0.86); p = 0.01], and DunedinPACE [AUC = 0.73, 95% CI (0.57-0.88); p = < 0.01] measures showed the greatest potential to identify clinical frailty using the I2. CONCLUSIONS: Our pilot data suggest that multiple blood-based aging biomarkers have potential to identify frailty in older adults with HM. IMPLICATIONS FOR CANCER SURVIVORS: We developed the I2 index to quantify impairments across geriatric domains and discovered that PBTL p16, Hannum, PhenoAge, and DunedinPACE are promising indicators of frailty in HM.

Trajectories of Health Care Contact Days for Patients With Stage IV Non-Small Cell Lung Cancer.

Importance: Patients with stage IV non-small cell lung cancer (NSCLC) experience substantial morbidity and mortality. Contact days (ie, the number of days with health care contact outside the home) measure how much of a person's life is consumed by health care, yet little is known about patterns of contact days for patients with NSCLC. Objective: To describe the trajectories of contact days in patients with stage IV NSCLC and how trajectories vary by receipt of cancer-directed treatment in routine practice. Design, Setting, and Participants: A retrospective, population-based decedent cohort study was conducted in Ontario, Canada. Participants included adults aged 20 years or older who were diagnosed with stage IV NSCLC (January 1, 2014, to December 31, 2017) and died (January 1, 2014, to December 31, 2019); there was a maximum 2-year follow-up. Data analysis was conducted from February 22 to August 16, 2023. Exposure: Systemic cancer-directed therapy (yes or no) and type of therapy (chemotherapy vs immunotherapy vs targeted therapy). Main Outcomes and Measures: Contact days (days with health care contact, outpatient or institution-based, outside the home) were identified through administrative data. The weekly percentage of contact days and fitted models with cubic splines were quantified to describe trajectories from diagnosis until death. Results: A total of 5785 decedents with stage IV NSCLC were included (median age, 70 [IQR 62-77] years; 3108 [53.7%] were male, and 1985 [34.3%] received systemic therapy). The median overall survival was 108 (IQR, 49-426) days, median contact days were 36 (IQR, 21-62), and the median percentage that were contact days was 33.3%. A median of 5 (IQR, 2-10) days were spent with specialty palliative care. Patients who did not receive systemic therapy had a median overall survival of 66 (IQR, 34-130) days and median contact days of 28 (IQR, 17-44), of which a median of 5 (IQR, 2-9) days were spent with specialty palliative care. Overall and for subgroups, normalized trajectories followed a U-shaped distribution: contact days were most frequent immediately after diagnosis and before death. Patients who received targeted therapy had the lowest contact day rate during the trough (10.6%; vs immunotherapy, 15.4%; vs chemotherapy, 17.7%). Conclusions and Relevance: In this cohort study, decedents with stage IV NSCLC had a median survival in the order of 3.5 months and spent 1 in every 3 days alive interacting with the health care system outside the home. These results highlight the need to better support patients and care partners, benchmark appropriateness, and improve care delivery.

How a Medically Tailored Meal Intervention with Intensive Nutrition Counseling Created Active Coping with Behavior Change for Vulnerable Patients with Lung Cancer.

Purpose: The purpose of this study was to assess participants' perceptions and experiences while participating in a Food is Medicine medically tailored meal plus nutrition counseling intervention to create a theoretical explanation about how the intervention worked. Methods: This interpretive qualitative study included the use of semi-structured interviews with active intervention participants. Purposeful sampling included vulnerable (uninsured, rural zip code residency, racial/ethnic minority, 65 years old, and/or low-income) individuals with lung cancer treated at four cancer centers across the United States. Interviews were recorded, transcribed verbatim, and analyzed using conventional content analysis with principles of grounded theory. Results: Twenty individuals participated. Data analysis resulted in a theoretical explanation of the intervention's mechanism of action. The explanatory process includes 3 linked and propositional categories leading to patient resilience: engaging in treatment, adjusting to diagnosis, and active coping. The medically tailored meals plus intensive nutrition counseling engaged participants throughout treatment, which helped participants adjust to their diagnosis, leading to active coping through intentional self-care, behavior change, and improved quality of life. Conclusions: These findings provide evidence that a food is medicine intervention may buffer some of the adversity related to the diagnosis of lung cancer and create a pathway for participants to experience post-traumatic growth, develop resilience, and change behaviors to actively cope with lung cancer. Medically tailored meals plus intensive nutrition counseling informed by motivational interviewing supported individuals' adjustment to their diagnosis and resulted in perceived positive behavior change.

Lung cancer screening use among screening-eligible adults with disabilities.

BACKGROUND: Lung cancer screening (LCS) use among adults with disabilities has not been well characterized. We estimated the prevalence of LCS use by disability types and counts and investigated the association between disability counts and LCS utilization among LCS-eligible adults. METHODS: We used cross-sectional data from the 2019 Behavioral Risk Factor Surveillance System, Lung Cancer Screening Module. Based on the 2013 US Preventive Services Task Force criteria for LCS, the sample included 4407 LCS-eligible adults, aged 55-79 years, with current or former (quit smoking in the past 15 years) tobacco use history of at least 30 pack-years. Disability types included limitations in hearing, vision, cognition, mobility, self-care, and independent living. We also categorized respondents by number of disabilities (no disability, 1 disability, 2 disabilities, 3+ disabilities). We utilized descriptive statistics and multivariable logistic regression analyses to determine the association between disability counts and the receipt of LCS (yes/no) in the past 12 months. RESULTS: In 2019, 16.4% of LCS-eligible adults were screened for lung cancer. Overall, 49.6% of participants had no disability, and 14.5% had >3 disabilities. Mobility was the most prevalent disability type (35.4%), followed by cognitive impairment (18.2%) and hearing (16.6%). LCS was more prevalent in adults with disability in self-care versus no disability in self-care (24.0% vs. 15.5%, p = 0.01), disability in independent living versus no disability in independent living (22.2% vs. 15.4%, p = 0.02), and cognitive impairment disability versus no cognitive impairment (22.1% vs. 15.3%, p = 0.03). The prevalence rates of LCS among groups of LCS-eligible adults with different disability counts were not significant (p = 0.17). CONCLUSIONS: Despite the lack of clinical guidelines on LCS among individuals with disabilities, some individuals with disabilities are being screened for lung cancer. Future research should address this knowledge gap to determine clinical benefit versus harm of LCS among those with disabilities.

A Phase 2 Trial of Primary Tumor Stereotactic Body Radiation Therapy Boost Before Concurrent Chemoradiation for Locally Advanced Non-Small Cell Lung Cancer.

PURPOSE: Primary tumor failure is common in patients treated with chemoradiation (CRT) for locally advanced NSCLC (LA-NSCLC). Stereotactic body radiation therapy (SBRT) yields high rates of primary tumor control (PTC) in early-stage NSCLC. This trial tested an SBRT boost to the primary tumor before the start of CRT to improve PTC. METHODS AND MATERIALS: Patients with LA-NSCLC received an SBRT boost in 2 fractions (central location 12 Gy, peripheral location 16 Gy) to the primary tumor, followed by standard CRT (60 Gy in 30 fractions). The primary objective was PTC rate at 1 year, and the hypothesis was that the 1-year PTC rate would be ≥90%. Secondary objectives included objective response rate, regional and distant control, disease-free survival (DFS), and overall survival (OS). Correlative studies included functional magnetic resonance imaging and blood-based miRNA analysis. RESULTS: The study enrolled 21 patients (10 men and 11 women); the median age was 62 years (range, 52-78). The median pretreatment primary tumor size was 5.0 cm (range, 1.0-8.3). The most common nonhematologic toxicities were pneumonitis, fatigue, esophagitis/dysphagia, dyspnea, and cough. Only 1 treatment-related grade 4 nonhematologic toxicity occurred (respiratory failure/radiation pneumonitis), and no grade 5 toxicities occurred. The objective response rate at 3 and 6 months was 72.7% and 80.0%, respectively, and PTC at 1 and 2 years was 100% and 92.3%, respectively. The 2-year regional and distant control rates were 81.6% and 70.3%, respectively. Disease-free survival and overall survival at 2 years were 46.1% and 50.3%, respectively, and median survival was 37.8 months. Functional magnetic resonance imaging detected a mean relative decrease in blood oxygenation level-dependent signal of -87.1% (P = .05), and miR.142.3p was correlated with increased risk of grade ≥3 pulmonary toxicity (P = .01). CONCLUSIONS: Dose escalation to the primary tumor using upfront SBRT appears feasible and safe. PTC was high and other oncologic endpoints compared favorably to standard treatment. Functional magnetic resonance imaging suggested changes in oxygenation with the first SBRT boost dose, and miR.142.3p was correlated with pulmonary toxicity.

A Video Intervention to Improve Patient Understanding of Tumor Genomic Testing in Patients with Cancer.

Background: Tumor genomic testing (TGT) has become standard-of-care for most patients with advanced/metastatic cancer. Despite established guidelines, patient education prior to TGT is variable or frequently omitted. The purpose of this study was to evaluate the impact of a concise (3-4 minute) video for patient education prior to TGT. Methods: Based on a quality improvement cycle, an animated video was created to be applicable to any cancer type, incorporating culturally diverse images, available in English and Spanish. Patients undergoing standard-of care TGT were enrolled at a tertiary academic institution and completed validated survey instruments immediately prior to video viewing (T1) and immediately post-viewing (T2). Instruments included: 1) 10-question objective genomic knowledge/understanding; 2) 10-question video message-specific knowledge/recall; 3) 11-question Trust in Physician/Provider; 4) attitudes regarding TGT. The primary objective was change in outcomes from before to after the video was assessed with Wilcoxon signed rank test. Results: From April 2022 to May 2023, a total of 150 participants were enrolled (MBC n=53, LC n=38, OC n=59). For the primary endpoint, there was a significant increase in video message-specific knowledge (median 10 point increase; p<0.0001) with no significant change in genomic knowledge/understanding (p=0.89) or Trust in Physician/Provider (p=0.59). Results for five questions significantly improved, including the likelihood of TGT impact on treatment decision, incidental germline findings, and cost of testing. Improvement in video message-specific knowledge was consistent across demographic groups, including age, income, and education. Individuals with less educational attainment had had greater improvement from before to after video viewing. Conclusions: A concise, 3-4 minute, broadly applicable video incorporating culturally diverse images administered prior to TGT significantly improved video message-specific knowledge across all demographic groups. This resource is publicly available at http://www.tumor-testing.com, with a goal to efficiently educate and empower patients regarding TGT while addressing guidelines within the flow of clinical practice. Clinical Trial Registration: ClinicalTrials.gov NCT05215769.

Association Between Pretreatment Chest Imaging and Immune Checkpoint Inhibitor Pneumonitis Among Patients With Lung Cancer.

BACKGROUND: Immune checkpoint inhibitors (ICIs) are a first-line and perioperative treatment for lung cancer. Pneumonitis is a potentially life-threatening complication of ICI treatment in 2% to 5% of patients; however, risk factors for developing ICI pneumonitis (ICI-p) remain undefined. METHODS: We conducted a retrospective cohort study of consecutive patients with lung cancer who received at least one dose of ICI from 2015 through 2020 at The Ohio State University. Pneumonitis cases were documented by the treating oncologist and retrospectively evaluated for agreement between an oncologist and a pulmonologist. Patient demographic and clinical characteristics were recorded and summarized between those with and without pneumonitis for the overall cohort. Univariate and multivariable survival analyses using the Fine-Gray competing risk model were used to examine the associations. RESULTS: A total of 471 patients with lung cancer were included, of which 402 had non-small cell lung cancer and 69 had small cell lung cancer; 39 (8%) patients in the overall cohort developed ICI-p. Preexisting interstitial abnormalities and prior chest radiation were both significantly associated with ICI-p on univariate analysis (hazard ratio [HR], 8.91; 95% CI, 4.69-16.92; P<.001; and HR, 2.81; 95% CI, 1.50-5.28; P=.001). On multivariable analyses, interstitial abnormalities remained a strong independent risk factor for ICI-p when controlling for chest radiation and type of immunotherapy (HR, 9.77; 95% CI, 5.17-18.46; P<.001). Among patients with ICI-p (n=39), those with severe (grade 3-5) pneumonitis had worse overall survival compared with those with mild (grade 1 or 2) pneumonitis (P=.001). Abnormal pulmonary function test results at both 12 and 18 months prior to ICI initiation were not significantly associated with ICI-p. CONCLUSIONS: Preexisting interstitial abnormalities on chest CT and prior chest radiation are independent risk factors that are strongly associated with ICI-p in patients with lung cancer. These findings highlight a potential need for closer observation for ICI-p among patients with these risk factors.

Disparities in outcomes between Black and White patients in North America with thoracic malignancies and COVID-19 infection (TERAVOLT).

BACKGROUND: Patients with thoracic malignancies who develop COVID-19 infection have a higher hospitalization rate compared to the general population and to those with other cancer types, but how this outcome differs by race and ethnicity is relatively understudied. METHODS: The TERAVOLT database is an international, multi-center repository of cross-sectional and longitudinal data studying the impact of COVID-19 on individuals with thoracic malignancies. Patients from North America with thoracic malignancies and confirmed COVID-19 infection were included for this analysis of racial and ethnic disparities. Patients with missing race data or races and ethnicities with fewer than 50 patients were excluded from analysis. Multivariable analyses for endpoints of hospitalization and death were performed on these 471 patients. RESULTS: Of the 471 patients, 73% were White and 27% were Black. The majority (90%) were non-Hispanic ethnicity, 5% were Hispanic, and 4% were missing ethnicity data. Black patients were more likely to have an Eastern Cooperative Oncology Group (ECOG) Performance Status ≥ 2 (p-value = 0.04). On multivariable analysis, Black patients were more likely than White patients to require hospitalization (Odds Ratio (OR): 1.69, 95% CI: 1.01-2.83, p-value = 0.044). These differences remained across different waves of the pandemic. However, no statistically significant difference in mortality was found between Black and White patients (OR 1.29, 95% CI: 0.69-2.40, p-value = 0.408). CONCLUSIONS: Black patients with thoracic malignancies who acquire COVID-19 infection are at a significantly higher risk of hospitalization compared to White patients, but there is no significant difference in mortality. The underlying drivers of racial disparity among patients with thoracic malignancies and COVID-19 infection require ongoing investigation.

Changes in physical function in older women with endometrial cancer with or without adjuvant therapy.

OBJECTIVE: To evaluate changes in physical function (PF) for older women with endometrial cancer (EC) + / - adjuvant therapy in the Women's Health Initiative Life and Longevity after Cancer cohort. MATERIALS AND METHODS: This study examined women ≥ 70 years of age with EC with available treatment records. Change in PF was measured using the RAND-36 and compared between groups using Wilcoxon rank-sum tests. Multivariable median regression was used to compare the changes in scores while adjusting for confounding variables. RESULTS: Included in the study were 287 women, 150 (52.3%) women who did not receive adjuvant therapy and 137 (47.7%) who received adjuvant therapy. When comparing PF scores, there was a statistically significant difference in the median percent change in functional decline, with a greater decline in those who received adjuvant therapy (- 5.9% [- 23.5 to 0%]) compared to those who did not (0 [- 18.8 to + 6.7%]), p = 0.02). Results were not statistically significant after multivariable adjustment, but women who underwent chemotherapy had a greater percent change (median ∆ - 13.8% [- 35.5 to 0%]) compared to those who received radiation alone (median ∆ - 5.9% [- 31.3 to 0%]) or chemotherapy and radiation (median ∆ - 6.5% [- 25.8 to + 5.7%]. CONCLUSIONS: Older women with EC who received adjuvant therapy experienced greater change in PF than those who did not receive adjuvant therapy, particularly women who received chemotherapy. These results were not statistically significant on multivariate analysis. IMPLICATIONS FOR CANCER SURVIVORS: EC survivors may experience changes in PF because of chemotherapy and/or radiation therapy. Additional supportive care may need to be provided to older women to mitigate functional decline.

Reducing hospital admissions in patients with malignant pleural effusion: a quality improvement study.

BACKGROUND: Malignant pleural effusions (MPE) can cause severe dyspnoea leading to greater than 125 000 hospitalisations per year and cost greater than US$5 billion per year in the USA. Timely insertion of tunnelled pleural catheters (TPCs) is associated with fewer inpatient days and emergency department visits. We conducted a quality improvement study to reduce hospital admissions of patients with MPE. METHODS: Key stakeholders were surveyed, including thoracic and breast oncology teams, general pulmonary and interventional pulmonology (IP) to help identify the underlying causes and solutions. Our preintervention group consisted of 51 patients who underwent TPC placement by our IP service. In our first intervention, we reviewed referrals for MPE with the scheduling team and triaged them based on urgency. In the second intervention, we added a follow-up phone call 1 week after the initial thoracentesis performed by IP to assess for the recurrence of symptoms. RESULTS: Demographic and clinical characteristics were summarised across the three groups. We evaluated the rate ratio (RR) of admissions in the intervention groups with the multivariable Poisson regression and adjusted for race, gender and cancer. Compared with the preintervention group, intervention I showed trends towards a 41% lower hospital admission rate (RR 0.59 (0.33-1.07), p=0.11). Compared with the preintervention group, intervention II showed trends towards a 40% lower hospital admission rate (RR 0.6 (0.36-0.99), p=0.07). The results did not reach statistical significance. Exploratory comparisons in readmission rates between interventions I and II showed no difference (RR 0.89 (0.43-1.79), p=0.75). CONCLUSIONS: Both interventions showed trends toward fewer hospital readmissions although they were not statistically significant. Larger-size prospective studies would be needed to demonstrate the continued effectiveness of these interventions.

Improving Access to Early Palliative Care Delivery for Patients With an Advanced Thoracic Malignancy Through an Embedded Oncopalliative Clinic Model.

PURPOSE: Early integration of palliative care (PC) with standard oncology care is driving the development of innovative PC delivery models. METHODS: This was a single-institution retrospective study of outpatient PC before and after the opening of an embedded thoracic oncology-palliative clinic at The Ohio State University. Patients included in the preintervention (October 2017-July 2018) and postintervention (October 2018-July 2019) cohorts had a diagnosis of any non-small-cell lung cancer (stages I-IV) or small-cell lung cancer (limited or extensive stage) and were newly established in the thoracic medical oncology clinic during the study time periods. All patients in the preintervention cohort had access to outpatient PC through a freestanding clinic, while the postintervention cohort had access to both freestanding and embedded clinics. Using time-to-event analyses, we evaluated differences in time intervals from first medical oncology visit to PC referral and first PC visit between cohorts. RESULTS: The majority of patients in both cohorts had metastatic disease at diagnosis. In the postintervention cohort, 20.9% of patients were referred to outpatient PC compared with 9.2% in the preintervention cohort (P < .01). PC referrals for patients outside of Franklin and adjacent counties increased from 4.0% to 14.2% after opening the embedded clinic (P < .01). Completion percentages of PC referrals increased from 57.6% to 76.0% in the preintervention versus postintervention cohorts (P = .048). Median time from palliative referral order to first PC visit decreased from 29 to 20 days (P = .047). Similarly, median time from the first oncology visit to PC referral completion decreased from 103 to 41 days (P = .08). CONCLUSION: Implementation of an embedded PC model was associated with increased access to early PC among patients with thoracic malignancies.

A cognitive-behavioral model of dyspnea: Qualitative interviews with individuals with advanced lung cancer.

OBJECTIVES: Shortness of breath, or dyspnea, is the subjective experience of breathing discomfort and is a common, distressing, and debilitating symptom of lung cancer. There are no efficacious pharmacological treatments, but there is suggestive evidence that cognitive-behavioral treatments could relieve dyspnea. For this, understanding the psychological, behavioral, and social factors that may affect dyspnea severity is critical. To this end, patients with dyspnea were interviewed with questions framed by the cognitive-behavioral model-emphasizing thoughts, emotions, and behaviors as contributors and outcomes of dyspnea. METHODS: Two trained individuals conducted semi-structured interviews with lung cancer patients (N = 15) reporting current dyspnea. Interviews assessed patients' cognitive-behavioral experiences with dyspnea. Study personnel used a grounded theory approach for qualitative analysis to code the interviews. Inter-rater reliability of codes was high (κ = 0.90). RESULTS: Thoughts: Most common were patients' catastrophic thoughts about their health and receiving enough oxygen when breathless. Emotions: Anxiety about dyspnea was the most common, followed by anger, sadness, and shame related to dyspnea. Behaviors: Patients rested and took deep breaths to relieve acute episodes of dyspnea. To reduce the likelihood of dyspnea, patients planned their daily activity or reduced their physical activity at the expense of engagement in hobbies and functional activities. SIGNIFICANCE OF RESULTS: Patients identified cognitive-behavioral factors (thoughts, emotions, and behaviors) that coalesce with dyspnea. The data provide meaningful insights into potential cognitive-behavioral interventions that could target contributors to dyspnea.

Clinical outcomes of immunotherapy continued beyond radiographic disease progression in older adult patients with advanced non­small cell lung cancer.

Immunotherapy is an effective and generally well-tolerated treatment strategy for older adult patients (aged ≥70 years) with advanced non-small cell lung cancer (NSCLC). Unfortunately, most patients who receive immunotherapy eventually exhibit disease progression during treatment. The present study reports on a subset of older adult patients with advanced NSCLC who could effectively continue immunotherapy beyond radiographic disease progression due to perceived clinical benefit. Local consolidative radiotherapy may be used in select older adult patients to prolong the duration of immunotherapy they receive, with a particular consideration of their preexisting co-morbidities, performance status and tolerance of potential toxicities associated with combined modality therapy. However, prospective research is needed to determine which patients benefit most from the addition of local consolidative radiotherapy, including whether type of disease progression (i.e., sites of progression, pattern of progression) and/or extent of consolidation offered (i.e., complete or incomplete) impact clinical outcomes. Further research is also warranted to determine which patients would most benefit from the continuation of immunotherapy beyond documented radiographic disease progression.
