Lung Nodule Prospective Database

Lung cancer is one of the most common cancers in the Singapore population, being the 2nd most commonly diagnosed cancer amongst males and 3rd most commonly diagnosed cancer amongst females. Pulmonologists, oncologists and thoracic surgeons are often consulted for the evaluation of imaging-identified pulmonary nodules. These may have been identified either incidentally or through screening. The majority of these are indeterminate and definitive investigation with biopsy or resection is invasive and not without risk. Hence, current consensus guidelines adopt a largely expectant strategy in the management of these indeterminate pulmonary nodules. There is substantial evidence that lung cancer in Asians may be unique with multiple driver mutations, lower age of presentation and may be independent of tobacco exposure. In addition, there are guidelines that recommend that the management of lung nodules in Asia should account for these differences. However, the evidence for alternative recommendations is lacking. The aim of the study will be to identify radiological and clinical predictors that can improve the diagnosis of lung nodules. These predictors may help build a model for lung nodule evaluation and surveillance. Prospective database of subjects meeting all of the following inclusion criteria to participate in this study.

1. 1.Evidence of lung nodule on chest radiograph or Computed Tomography regardless of underlying aetiology
2. 2.Age ³ 21 years old
3. 3.Ability to provide informed consent This study will collect existing or prospective data that is part of standard clinical care from the electronic medical record of patients (ambulatory and inpatient from May 2018-2023.
