Factors influencing surgical choice and anxiety in patients with pulmonary nodules smaller than 8 mm

Background: The detection of pulmonary nodules significantly impacts the lives and mental health of patients. Although the 2020 National Comprehensive Cancer Network (NCCN) guidelines recommend scheduled surveillance for nodules <= 8 mm, patients often opt to have their nodules surgically removed.Methods: A cross-sectional questionnaire was administered to patients with small pulmonary nodules who presented to a local grade 3 hospital with small pulmonary nodules and decided to receive surgery versus prescribed monitoring. The questionnaire included four aspects: (I) patient characteristics; (II) nodule specific knowledge; (III) doctor-patient communication; and (IV) nodular-specific distress. Nodular-specific distress was measured by the Impact of Event Scale-Revised (IES-R).Results: A total of 234 (69%) patients responded to the survey and were included in the final analysis. Poor performance in activities of daily living (ADLs), the presence of solid nodules, multifocal disease, and a family history of lung cancer were significantly associated with reported anxiety. Most notably, facilitating patient choice for surgery was the computed tomography (CT) scan results, with reference to lung nodule size and number of nodules, where concerns related to lung nodule, cancer risk, and fear of surgery or death had a significant psychological impact on patients. Conclusions: In this cohort of patients who elected to have their small pulmonary nodules surgically removed, we identified key factors underlying their anxiety toward guideline recommended surveillance. Our findings will be useful for clinicians when discussing treatment options with their patients.
