Emergency department associated lung cancer diagnosis: Case series demonstrating poor outcomes and opportunities to improve cancer care

Diagnosis of cancer in the Emergency Department: A scoping review

BACKGROUND

The Emergency Department (ED) plays a key role in the identification and care of acute medical conditions, including cancer. In this scoping review, we aimed to determine the role of the ED in the acute diagnosis of cancer.

METHODS

We conducted a scoping review of articles according to Preferred Reporting Items for Systematic Review and Meta-Analyses (PRISMA) using PubMed and Google Scholar. We screened studies of adults with a new diagnosis of cancer in the ED. We included randomized control trials, prospective, retrospective, and cross-sectional observational studies, and case reports published in English since 2000. We grouped the articles into categories based on their objectives and findings.

RESULTS

Of the 4459 articles, we included 47 in the review. The identified studies fell into three major categories: (1) studies describing the incidental diagnosis of cancer in the ED (n = 11, 23%), (2) studies characterizing the acute initial presentation of cancer in the ED (n = 19, 41%), and (3) studies describing the ED as a pathway to cancer diagnosis in the healthcare system (n = 17, 36%). Across the studies, cancer diagnoses in the ED were more likely in patients with higher comorbidities, occurred at later stages, and resulted in worse survival rates.

CONCLUSIONS

The ED plays a prominent role in the initial diagnosis of cancer. Efforts must be made to integrate the ED within the cancer care continuum.

New lung cancer diagnosis after emergency department presentation in a tertiary hospital: patient characteristics and outcomes

OBJECTIVES

Currently there is limited data available about patients who are diagnosed with lung cancer following an emergency department (ED) visit. This study sought to define the demographics, symptoms profile, staging, and prognosis of this cohort of patients.

METHODS

We conducted a retrospective study of patients diagnosed with a primary lung malignancy at a lung cancer multi-disciplinary meeting between January 2018-January 2020. Medical records were reviewed to collect data around demographics, presenting symptoms, investigations, admission, cancer stage, and mortality.

RESULTS

During the study period, 890 patients were diagnosed with a primary lung malignancy of which 209 (23.5%) presented to ED prompting diagnostic work-up. Of these 209 patients, 89% were hospitalised for a median duration of 6 days. 104 (50%) were female and average age of cohort was 70 years. Dyspnoea (38%) was the most common presenting symptom. Radiological staging and tissue biopsy was performed as an outpatient procedure in 46% and 41% of patients respectively. 188 patients had non-small cell lung cancer of whom 68% had Stage IV disease. 53 (25%) patients died within 3 months of ED presentation. These patients were older with more advanced disease compared to patients who were alive at 3 months.

CONCLUSION

: Emergent diagnosed patients are a significant proportion of the lung cancer population, presenting with advanced stage disease and increased short-term mortality. Future research should be directed at interventions, such as lung cancer screening program and/or community education to reduce the need for patients to present the emergency department with disabling lung cancer symptoms.
