Objective

Older patients with non-small cell lung cancer (NSCLC) are less likely to receive guideline-recommended treatment at diagnosis, independent of comorbidity. However, national data on treatment of postoperative recurrence are limited. We evaluated the associations between age, comorbidity, and other patient factors and treatment of postoperative NSCLC recurrence in a national cohort.

Materials and methods

We randomly selected 9001 patients with surgically resected stage I-III NSCLC in 2006-2007 from the National Cancer Data Base. Patients were followed for 5 years or until first NSCLC recurrence, new primary cancer, or death, whichever came first. Perioperative comorbidities, first recurrence, treatment of recurrence, and survival were abstracted from medical records and merged with existing registry data. Factors associated with active treatment (chemotherapy, radiation, and/or surgery) versus supportive care only were analyzed using multivariable logistic regression.

Results

Median age at initial diagnosis was 67; 69.7% had >1 comorbidity. At 5-year follow-up, 12.3% developed locoregional and 21.5% developed distant recurrence. Among patients with locoregional recurrence, 79.5% received active treatment. Older patients (OR 0.49 for age >75 compared with <55; 95% CI 0.27-0.88) and those with substance abuse (OR 0.43; 95% CI 0.23-0.81) were less likely to receive active treatment. Women (OR 0.62; 95% CI 0.43-0.89) and patients with symptomatic recurrence (OR 0.69; 95% CI 0.47-0.99) were also less likely to receive active treatment. Among those with distant recurrence, 77.3% received active treatment. Older patients (OR 0.42 for age >75 compared with <55; 95% CI 0.26-0.68) and those with any documented comorbidities (OR 0.59; 95% CI 0.38-0.89) were less likely to receive active treatment.

Conclusion

Older patients independent of comorbidity, patients with substance abuse, and women were less likely to receive active treatment for postoperative NSCLC recurrence. Studies to further characterize these disparities in treatment of NSCLC recurrence are needed to identify barriers to treatment.

Cardiovascular morbidity and mortality as a result of inhaled tobacco products continues to be a global healthcare crisis, particularly in low- and middle-income nations lacking the infrastructure to develop and implement effective public health policies limiting tobacco use. Following initiation of public awareness campaigns 50 years ago in the United States, considerable success has been achieved in reducing the prevalence of cigarette smoking and exposure to secondhand smoke. However, there has been a slowing of cessation rates in the United States during recent years, possibly caused by high residual addiction or fatigue from cessation messaging. Furthermore, tobacco products have continued to evolve faster than the scientific understanding of their biological effects. This review considers selected updates on the genetics and epigenetics of smoking behavior and associated cardiovascular risk, mechanisms of atherogenesis and thrombosis, clinical effects of smoking and benefits of cessation, and potential impact of electronic cigarettes on cardiovascular health.

Objectives

This study sought to quantify and compare the decline in volumes of cardiovascular procedures between the United States and non-U.S. institutions during the early phase of the coronavirus disease-2019 (COVID-19) pandemic.

Background

The COVID-19 pandemic has disrupted the care of many non-COVID-19 illnesses. Reductions in diagnostic cardiovascular testing around the world have led to concerns over the implications of reduced testing for cardiovascular disease (CVD) morbidity and mortality.

Methods

Data were submitted to the INCAPS-COVID (International Atomic Energy Agency Non-Invasive Cardiology Protocols Study of COVID-19), a multinational registry comprising 909 institutions in 108 countries (including 155 facilities in 40 U.S. states), assessing the impact of the COVID-19 pandemic on volumes of diagnostic cardiovascular procedures. Data were obtained for April 2020 and compared with volumes of baseline procedures from March 2019. We compared laboratory characteristics, practices, and procedure volumes between U.S. and non-U.S. facilities and between U.S. geographic regions and identified factors associated with volume reduction in the United States.

Results

Reductions in the volumes of procedures in the United States were similar to those in non-U.S. facilities (68% vs. 63%, respectively; p = 0.237), although U.S. facilities reported greater reductions in invasive coronary angiography (69% vs. 53%, respectively; p < 0.001). Significantly more U.S. facilities reported increased use of telehealth and patient screening measures than non-U.S. facilities, such as temperature checks, symptom screenings, and COVID-19 testing. Reductions in volumes of procedures differed between U.S. regions, with larger declines observed in the Northeast (76%) and Midwest (74%) than in the South (62%) and West (44%). Prevalence of COVID-19, staff redeployments, outpatient centers, and urban centers were associated with greater reductions in volume in U.S. facilities in a multivariable analysis.

Conclusions

We observed marked reductions in U.S. cardiovascular testing in the early phase of the pandemic and significant variability between U.S. regions. The association between reductions of volumes and COVID-19 prevalence in the United States highlighted the need for proactive efforts to maintain access to cardiovascular testing in areas most affected by outbreaks of COVID-19 infection.
