Lung Cancer Survival Trends in the Veterans Health Administration.

INTRODUCTION: Lung cancer survival is improving in the United States. We investigated whether there was a similar trend within the Veterans Health Administration (VHA), the largest integrated healthcare system in the United States. MATERIALS AND METHODS: Data from the Veterans Affairs Central Cancer Registry were analyzed for temporal survival trends using Kaplan-Meier estimates and linear regression. RESULTS: A total number of 54,922 Veterans were identified with lung cancer diagnosed from 2010 to 2017. Histologies were classified as non-small-cell lung cancer (NSCLC) (64.2%), small cell lung cancer (SCLC) (12.9%), and 'other' (22.9%). The proportion with stage I increased from 18.1% to 30.4%, while stage IV decreased from 38.9% to 34.6% (both P < .001). The 3-year overall survival (OS) improved for stage I (58.6% to 68.4%, P < .001), stage II (35.5% to 48.4%, P < .001), stage III (18.7% to 29.4%, P < .001), and stage IV (3.4% to 7.8%, P < .001). For NSCLC, the median OS increased from 12 to 21 months (P < .001), and the 3-year OS increased from 24.1% to 38.3% (P < .001). For SCLC, the median OS remained unchanged (8 to 9 months, P = .10), while the 3-year OS increased from 9.1% to 12.3% (P = .014). Compared to White Veterans, Black Veterans with NSCLC had similar OS (P = .81), and those with SCLC had higher OS (P = .003). CONCLUSION: Lung cancer survival is improving within the VHA. Compared to White Veterans, Black Veterans had similar or higher survival rates. The observed racial equity in outcomes within a geographically and socioeconomically diverse population warrants further investigation to better understand and replicate this achievement in other healthcare systems.

Adverse Events Following Limited Resection versus Stereotactic Body Radiation Therapy for Early Stage Lung Cancer.

Rationale: Approximately a quarter of patients with early stage lung cancer are not medically fit for lobectomy. Limited resection and stereotactic body radiation therapy (SBRT) have emerged as alternatives for these patients. Given the equipoise on the effectiveness of the two treatments, treatment-related adverse events (AEs) could have a significant impact on patients' decision-making and treatment outcomes. Objectives: To compare the AE profile between SBRT versus limited resection. Methods: Data were derived from a prospective cohort of patients with stage I-IIA non-small cell lung cancer who were deemed as high-risk for lobectomy recruited from five centers across the United States. Propensity scores and inverse probability weighting were used to compare the rates of 30- and 90-day AEs among patients treated with limited resection versus SBRT. Results: Overall, 65% of 252 patients underwent SBRT. After adjusting for propensity scores, there was no significant difference in developing at least one AE comparing SBRT to limited resection (odds ratio [OR]: 1.00; 95% confidence interval [CI]: 0.65-1.55 and OR: 1.27; 95% CI: 0.84-1.91 at 30 and 90 days, respectively). SBRT was associated with lower risk of infectious AEs than limited resection at 30 days (OR: 0.05; 95% CI: 0.01-0.39) and 90 days posttreatment (OR: 0.41; 95% CI: 0.17-0.98). Additionally, SBRT was associated with persistently elevated risk of fatigue (OR: 2.47; 95% CI: 1.34-4.54 at 30 days and OR: 2.69; 95% CI: 1.52-4.77 at 90 days, respectively), but significantly lower risks of respiratory AEs (OR: 0.36; 95% CI: 0.20-0.65 and OR: 0.51; 95% CI: 0.31-0.86 at 30 and 90 days, respectively). Conclusions: Though equivalent in developing at least one AE, we found that SBRT is associated with less toxicity than limited resection in terms of infectious and respiratory AEs but higher rates of fatigue that persisted up to 3 months posttreatment. This information, combined with data about oncologic effectiveness, can help patients' decision-making regarding these alternative therapies.

Association of Palliative Care Use and Setting With Health-care Utilization and Quality of Care at the End of Life Among Patients With Advanced Lung Cancer.

BACKGROUND: Palliative care is associated with improved survival and quality of life among patients with lung cancer; however, its influence on health-care utilization and quality of care is unclear. RESEARCH QUESTION: Is palliative care, and the setting in which it occurs, associated with health-care resource utilization and quality of care among patients with advanced lung cancer? STUDY DESIGN AND METHODS: This was a retrospective cohort study of 23,142 patients with stage IIIB/IV lung cancer in the Veterans Affairs HealthCare System between 2007 and 2013. Exposures included the receipt of specialist-delivered palliative care, and the setting of the initial palliative care encounter (inpatient or outpatient) received after cancer diagnosis. Primary outcomes included rates of ED visits, along with rates of hospitalization and odds of ICU admission within the last 30 days of life. Secondary outcomes included any health-care utilization (ED, hospital, or ICU) related to chemotherapy toxicity. We used propensity score methods to perform Poisson and logistic regression modeling. RESULTS: Among the 23,142 patients, 57% received palliative care, and 36% of initial palliative care encounters were outpatient. Compared with no palliative care, initial palliative care encounter in the outpatient setting was associated with reduced rates of ED visits (adjusted incidence rate ratio [aIRR], 0.86; 95% CI, 0.77-0.96) and hospitalizations in the last 30 days of life (aIRR, 0.64; 95% CI, 0.59-0.70). Initial palliative care encounters in both inpatient (adjusted OR [aOR], 0.63; 95% CI, 0.53-0.75) and outpatient (aOR, 0.42; 95% CI, 0.35-0.52) settings were associated with reduced odds of ICU admission in the last 30 days of life. Palliative care was also associated with reduced health-care utilization related to chemotherapy toxicity (aOR, 0.88; 95% CI, 0.82-0.95). INTERPRETATION: Palliative care (particularly in outpatient settings) is associated with reduced health-care utilization at the end of life and may improve the quality of care among patients with advanced lung cancer. These findings support the role of palliative care as an important component of comprehensive cancer care and highlight the potential benefits of outpatient palliative care services.

Association of Early Palliative Care Use With Survival and Place of Death Among Patients With Advanced Lung Cancer Receiving Care in the Veterans Health Administration.

Importance: Palliative care is a patient-centered approach associated with improvements in quality of life; however, results regarding its association with a survival benefit have been mixed, which may be a factor in its underuse. Objective: To assess whether early palliative care is associated with a survival benefit among patients with advanced lung cancer. Design, Setting, and Participants: This retrospective population-based cohort study was conducted among patients with lung cancer who were diagnosed with cancer between January 1, 2007, and December 31, 2013, with follow-up until January 23, 2017. Participants comprised 23 154 patients with advanced lung cancer (stage IIIB and stage IV) who received care in the Veterans Affairs health care system. Data were analyzed from February 15, 2019, to April 28, 2019. Exposure: Palliative care defined as a specialist-delivered palliative care encounter received after lung cancer diagnosis. Main Outcomes and Measures: The primary outcome was survival. The association between palliative care and place of death was also examined. Propensity score and time-varying covariate methods were used to calculate Cox proportional hazards and to perform regression modeling. Results: Of the 23 154 patients enrolled in the study, 57% received palliative care. The mean (SD) age of participants was 68 (9.5) years, and 98% of participants were men. An examination of the timing of palliative care receipt relative to cancer diagnosis found that palliative care received 0 to 30 days after diagnosis was associated with decreases in survival (adjusted hazard ratio [aHR], 2.13; 95% CI, 1.97-2.30), palliative care received 31 to 365 days after diagnosis was associated with increases in survival (aHR, 0.47; 95% CI, 0.45-0.49), and palliative care received more than 365 days after diagnosis was associated with no difference in survival (aHR, 1.00; 95% CI, 0.94-1.07) compared with nonreceipt of palliative care. Receipt of palliative care was also associated with a reduced risk of death in an acute care setting (adjusted odds ratio, 0.57; 95% CI, 0.52-0.64) compared with nonreceipt of palliative care. Conclusions and Relevance: The results suggest that palliative care was associated with a survival benefit among patients with advanced lung cancer. Palliative care should be considered a complementary approach to disease-modifying therapy in patients with advanced lung cancer.

Improvements in hospice utilization among patients with advanced-stage lung cancer in an integrated health care system.

BACKGROUND: Hospice, a patient-centered care system for those with limited life expectancy, is important for enhancing quality of life and is understudied in integrated health care systems. METHODS: This was a retrospective cohort study of 21,860 decedents with advanced-stage lung cancer diagnosed from January 2007 to June 2013 in the national US Veterans Affairs Health Care System. Trends over time, geographic regional variability, and patient and tumor characteristics associated with hospice use and the timing of enrollment were examined. Multivariable logistic regression and Cox proportional hazards modeling were used. RESULTS: From 2007 to 2013, 70.3% of decedents with advanced-stage lung cancer were enrolled in hospice. Among patients in hospice, 52.9% were enrolled in the last month of life, and 14.7% were enrolled in the last 3 days of life. Hospice enrollment increased (adjusted odds ratio [AOR], 1.07; P < .001), whereas the mean time from the cancer diagnosis to hospice enrollment decreased by 65 days (relative decrease, 32%; adjusted hazard ratio, 1.04; P < .001). Relative decreases in late hospice enrollment were observed in the last month (7%; AOR, 0.98; P = .04) and last 3 days of life (26%; AOR, 0.95; P < .001). The Southeast region of the United States had both the highest rate of hospice enrollment and the lowest rate of late enrollment. Patient sociodemographic and lung cancer characteristics were associated with hospice enrollment. CONCLUSIONS: Among patients with advanced-stage lung cancer in the Veterans Affairs Health Care System, overall and earlier hospice enrollment increased over time. Considerable regional variability in hospice enrollment and the persistence of late enrollment suggests opportunities for improvement in end-of-life care.

Readiness for Implementation of Lung Cancer Screening. A National Survey of Veterans Affairs Pulmonologists.

RATIONALE: To mitigate the potential harms of screening, professional societies recommend that lung cancer screening be conducted in multidisciplinary programs with the capacity to provide comprehensive care, from screening through pulmonary nodule evaluation to treatment of screen-detected cancers. The degree to which this standard can be met at the national level is unknown. OBJECTIVES: To assess the readiness of clinical facilities in a national healthcare system for implementation of comprehensive lung cancer screening programs, as compared with the ideal described in policy recommendations. METHODS: This was a cross-sectional, self-administered survey of staff pulmonologists in pulmonary outpatient clinics in Veterans Health Administration facilities. MEASUREMENTS AND MAIN RESULTS: The facility-level response rate was 84.1% (106 of 126 facilities with pulmonary clinics); 88.7% of facilities showed favorable provider perceptions of the evidence for lung cancer screening, and 73.6% of facilities had a favorable provider-perceived local context for screening implementation. All elements of the policy-recommended infrastructure for comprehensive screening programs were present in 36 of 106 facilities (34.0%); the most common deficiencies were the lack of on-site positron emission tomography scanners or radiation oncology services. Overall, 26.5% of Veterans Health Administration facilities were ideally prepared for lung cancer screening implementation (44.1% if the policy recommendations for on-site positron emission tomography scanners and radiation oncology services were waived). CONCLUSIONS: Many facilities may be less than ideally positioned for the implementation of comprehensive lung cancer screening programs. To ensure safe, effective screening, hospitals may need to invest resources or coordinate care with facilities that can offer comprehensive care for screening through downstream evaluation and treatment of screen-detected cancers.

"Even if I Don't Remember, I Feel Better". A Qualitative Study of Patients with Early-Stage Non-Small Cell Lung Cancer Undergoing Stereotactic Body Radiotherapy or Surgery.

RATIONALE: While surgical resection is recommended for most patients with early stage lung cancer according to the National Comprehensive Cancer Network guidelines, stereotactic body radiotherapy is increasingly being used. Provider-patient communication regarding the risks and benefits of each approach may be a modifiable factor leading to improved patient-centered outcomes. OBJECTIVES: To qualitatively describe the experiences of patients undergoing either surgery or stereotactic body radiotherapy for early stage non-small cell lung cancer. METHODS: We qualitatively evaluated and used content analysis to describe the experiences of 13 patients with early clinical stage non-small cell lung cancer before undergoing treatment in three health care systems in the Pacific Northwest, with a focus on knowledge obtained, communication, and feelings of distress. MEASUREMENTS AND MAIN RESULTS: Although most participants reported rarely having been told about other options for treatment and could not readily recall many details about specific risks of recommended treatment, they were satisfied with their care. The patients paradoxically described clinicians as displaying caring and empathy despite not explicitly addressing their concerns and worries. We found that the communication domains that underlie shared decision making occurred infrequently, but that participants were still pleased with their role in the decision-making process. We did not find substantially different themes based on where the participant received care or the treatment selected. CONCLUSIONS: Patients were satisfied with all aspects of their care, despite reporting little knowledge about risks or other treatment options, no direct elicitation of worries from providers, and a lack of shared decision making. While the development of effective communication strategies to address these gaps is warranted, their effect on patient-centered outcomes, such as distress and decisional conflict, is unclear.

Associations of herbal and specialty supplements with lung and colorectal cancer risk in the VITamins and Lifestyle study.

Millions of Americans use dietary supplements with little knowledge about their benefits or risks. We examined associations of various herbal/specialty supplements with lung and colorectal cancer risk. Men and women, 50 to 76 years, in the VITamins And Lifestyle cohort completed a 24-page baseline questionnaire that captured duration (years) and frequency (days per week) of use of commonly used herbal/specialty supplements. Dose was not assessed due to the lack of accurate potency information. Supplement exposure was categorized as "no use" or "any use" over the previous 10 years. Hazard ratios (HR) were estimated by multivariate Cox regression models. Incident lung (n = 665) and colorectal cancers (n = 428) were obtained from the Surveillance, Epidemiology, and End Results cancer registry. Any use of glucosamine and chondroitin, which have anti-inflammatory properties, over the previous 10 years, was associated with significantly lower lung cancer risk: HR 0.74 [95% confidence interval (95% CI), 0.58-0.94] and HR 0.72 (95% CI, 0.54-0.96) and colorectal cancer risk: HR 0.73 (95% CI, 0.54-0.98) and HR 0.65 (95% CI, 0.45-0.93), respectively. There were also statistically significantly inverse associations of fish oil: HR 0.65 (95% CI, 0.42-0.99), methylsulfonylmethane: HR 0.46 (95% CI, 0.23-0.93), and St. John's wort: HR 0.35 (95% CI, 0.14-0.85) with colorectal cancer risk. In contrast, garlic pills were associated with a statistically significant 35% elevated colorectal cancer risk. These results suggest that some herbal/specialty supplements may be associated with lung and colorectal cancer risk; however, these products should be used with caution. Additional studies examining the effects of herbal/specialty supplements on risk for cancer and other diseases are needed.

Long-term use of beta-carotene, retinol, lycopene, and lutein supplements and lung cancer risk: results from the VITamins And Lifestyle (VITAL) study.

High-dose beta-carotene supplementation in high-risk persons has been linked to increased lung cancer risk in clinical trials; whether effects are similar in the general population is unclear. The authors examined associations of supplemental beta-carotene, retinol, vitamin A, lutein, and lycopene with lung cancer risk among participants, aged 50-76 years, in the VITamins And Lifestyle (VITAL) cohort Study in Washington State. In 2000-2002, eligible persons (n = 77,126) completed a 24-page baseline questionnaire, including detailed questions about supplement use (duration, frequency, dose) during the previous 10 years from multivitamins and individual supplements/mixtures. Incident lung cancers (n = 521) through December 2005 were identified by linkage to the Surveillance, Epidemiology, and End Results cancer registry. Longer duration of use of individual beta-carotene, retinol, and lutein supplements (but not total 10-year average dose) was associated with statistically significantly elevated risk of total lung cancer and histologic cell types; for example, hazard ratio = 2.02, 95% confidence interval: 1.28, 3.17 for individual supplemental lutein with total lung cancer and hazard ratio = 3.22, 95% confidence interval: 1.29, 8.07 for individual beta-carotene with small-cell lung cancer for >4 years versus no use. There was little evidence for effect modification by gender or smoking status. Long-term use of individual beta-carotene, retinol, and lutein supplements should not be recommended for lung cancer prevention, particularly among smokers.

Long-term use of supplemental multivitamins, vitamin C, vitamin E, and folate does not reduce the risk of lung cancer.

RATIONALE: Lung cancer is the leading cause of cancer-related mortality in the United States. Although supplements are used by half the population, limited information is available about their specific effect on lung cancer risk. OBJECTIVES: To explore the association of supplemental multivitamins, vitamin C, vitamin E, and folate with incident lung cancer. METHODS: Prospective cohort of 77,721 men and women aged 50-76 years from Washington State in the VITAL (VITamins And Lifestyle) study. Cases were identified through the Seattle-Puget Sound SEER (Surveillance, Epidemiology, and End Results) cancer registry. MEASUREMENTS AND MAIN RESULTS: Hazard ratios (HRs) for incident lung cancer according to 10-year average daily use of supplemental multivitamins, vitamin C, vitamin E, and folate. A total of 521 cases of lung cancer were identified. Adjusting for smoking, age, and sex, there was no inverse association with any supplement. Supplemental vitamin E was associated with a small increased risk of lung cancer (HR, 1.05 for every 100-mg/d increase in dose; 95% confidence interval [CI], 1.00-1.09; P = 0.033). This risk of supplemental vitamin E was largely confined to current smokers (HR, 1.11 for every 100-mg/d increase; 95% CI, 1.03-1.19; P < 0.01) and was greatest for non-small cell lung cancer (HR, 1.07 for every 100-mg/d increase; 95% CI, 1.02-1.12; P = 0.004). CONCLUSIONS: Supplemental multivitamins, vitamin C, vitamin E, and folate were not associated with a decreased risk of lung cancer. Supplemental vitamin E was associated with a small increased risk. Patients should be counseled against using these supplements to prevent lung cancer.
