### What you need to know Pulmonary nodules are defined as focal opacities that measure up to 3 cm in diameter and are surrounded by lung parenchyma, including those abutting the pleura. The management of a solitary pulmonary nodule is best performed by using an interprofessional approach. The following is a summary of the 2017 Fleischner Society Guidelines. British Thoracic Society guidelines for the investigation and management of pulmonary nodules M E J Callister,1 D R Baldwin,2 A R Akram,3 S Barnard,4 P Cane,5 J Draffan,6 K Franks,7 F Gleeson,8 R Graham,9 P Malhotra,10 M Prokop,11 K Rodger,12 M Subesinghe,13 D Waller,14 I Woolhouse,15 British Thoracic Society Pulmonary Nodule Guideline Development Group, on behalf of the British Thoracic Society The 2005 Fleischner Society guideline stated that at least 99% of all nodules 4 mm or smaller are benign; when nodule is 5-9 mm in diameter, the best strategy is surveillance. British Thoracic Society guidelines for pulmonary nodules were published in August 2015 for the management of pulmonary nodules seen on CT. Background . Pulmonary Nodule Measurements A lesion which measures 8 x 5 mm has an average of (8 + 5) : 2 = 6.5 mm - rounded up to 7 mm A solitary pulmonary nodule is defined as a discrete lesion < 3 cm in diameter that is completely surrounded by lung parenchyma (ie, does not touch the hilum, mediastinum, or pleura) and is without associated atelectasis or pleural effusion. Nodule size, consistency (solid, partly solid, non-solid), the presence of calcification, and recommendations for follow-up were evaluated. Management of Incidentally detected solitary pulmonary nodule (SPN). Radiology 2005; 237:395. For suspicious nodules <6mm, consider 2 and 4 year f/u. 2. . 1-3 these guidelines are not intended to be rigid, since the treatment of spn is an example of how estimation of the probability of malignancy (pm), access to the various diagnostic and therapeutic techniques and … Benign versus Malignant. Pulmonary Neoplasms. If stable and <6mm solid component, then q12 months for 5 years. The risks from potential exposure to coronavirus disease 2019 (COVID-19), and resource reallocation that has occurred to combat the pandemic, have altered the balance of benefits and harms that informed current (pre-COVID-19) guideline recommendations for lung cancer screening and lung nodule evaluation. The National Comprehensive Cancer Network guidelines were updated in 2018 and the revised Fleischner Society guidelines were published in 2017. For nodules with particularly suspicious morphology, a growing solid component, or a solid component larger than 8mm, PET/CT, If solid nodule <6mm 6-8mm >8mm Notes Single Low risk No routine f/u CT at 6-12 months, then consider CT at 18-24 months Consider CT, PET/CT or biopsy at 3 months .

When I encounter a patient with a solitary pulmonary nodule on CT, I first review the images with a radiologist to ensure the accuracy of the initial reading. The Fleischner Society Guidelines for management of solid nodules were published in 2005. The Fleischner Society pulmonary nodule recommendations pertain to the follow-up and management of indeterminate pulmonary nodules detected incidentally on CT and are published by the Fleischner Society. This year the guidelines were updated to expand the flexibility for clinicians and patients in clinical decision making and to individualize the management of detected lesions. A quite common "incidentaloma" on imaging is an unexpected lung nodule. 2004;28(6):766-775. Fleischner Society Guidelines for Ground Glass and Subsolid Pulmonary Nodules 2013 Naidich DP et al. A solitary pulmonary nodule is defined as a discrete, well-marginated, rounded opacity less than or equal to 3 cm in diameter that is completely surrounded by . 13 All individuals are considered equally without risk stratification and subsolid nodules are assessed depending on their type and multiplicity. Solitary pulmonary nodule. Lacson R, Prevedello LM, Andriole KP, et al. Fleischner Society recommendations have recently been produced for the management of subsolid nodules. In 2005, the Fleischner Society published guidelines [25] for follow-up imaging of solitary pulmonary nodules (SPNs). The main purpose of these guidelines is to reduce the number of unnecessary computed tomography (CT) examinations during the follow-up of small indeterminate nodules. Solitary pulmonary nodule (SPN), defined as pulmonary opacity up to 30 mm in diameter, is a common finding in routine clinical practice when performing chest imaging tests such as radiographs or computed tomography for any reason [1, 2].The vast majority of these nodules are benign, and only a small proportion (around 10-20%) are malignant [3, 4]. Incidental Pulmonary Nodules Michael Wert, MD Assistant Professor - Clinical Department of Internal Medicine Division of Pulmonary, Critical Care, and Sleep Medicine The Ohio State University Wexner Medical Center 2 What is a (Solitary) Pulmonary Nodule? In 2005, the Fleischner Society published the first management guidelines for solid solitary pulmonary nodules 4; in 2013 the Society published its guidelines for subsolid nodules, 5 and, in 2017, it published the latest guidelines for the management of incidentally detected solitary, solid and subsolid pulmonary nodules.

Recommendation for part -solid nodules ≥6 mm solid component ≥6 mm • For solitary part-solid nodules with a solid component 6 mm or larger, a short -term follow-up CT scan at 3-6 monthsshould be considered. Solitary pulmonary nodule malignancy predictive models applicable to routine clinical practice: a systematic review Marina Senent‑Valero1*, Julián Librero2,3 and María Pastor‑Valero1,4 Abstract Background: Solitary pulmonary nodule (SPN) is a common nding in routine clinical practice when perform‑ ing chest imaging tests. Fleischner Society guidelines for CT surveillance of incidental solitary pulmonary nodules. <6mm do not require f/u, but high risk patient or nodule characteristics may warrant 12 month f/u. While most are benign, a significant number represent early, potentially curable lung cancers. According to the 2007 ACCP guidelines for the evaluation of solitary pulmonary nodules, the assessment of a nodule should be based primarily on two factors: the patient's risk of cancer and the . According to the Fleischner society, nodules <6 mm in diameter (or <100 mm 3 in volume) are considered small enough to discharge the patient, while the respective cutoff is somewhat lower (<5 mm or <80 mm 3) in the earlier ACCP and BTS guidelines,, based on the results of the study of Horeweg et al., who found that only nodules <5 mm (or <100 .

If the SPN is ≤8 mm, I follow the Fleischner guidelines; if the SPN is larger, I usually enlist specialist help, unless nodule characteristics (e.g., pattern of calcification) indicate . Objective . Pulmonary nodules have become a more common occurrence in the United States mostly due to radiologists finding them more regularly because of more frequent computed tomography (CT) use. The timing of these control examinations varies according to the nodule size (4-6, or 6-8 mm) and the type of patients, specifically at low or high risk of malignancy . •The average risk of cancer in an 8-mm solitary nodule is 3% depending on morphology and location •As nodules become larger, their morphology becomes more distinct, and management should be strongly influenced by the appearance of the nodule rather than by size alone N EnglJ Med 2013;369(10):910-919. The Fleischner guidelines are only applicable to patients aged at least 35 years in whom there is no prior diagnosis of cancer, and do not pertain to lung cancer screening-detected nodules.11 In contrast, the guideline development group of the BTS found insufficient evidence to recommend different approaches to managing pulmonary nodules .

A solitary pulmonary nodule is defined as a discrete, well-marginated, rounded opacity less than or equal to 3 cm in diameter that is completely surrounded by lung parenchyma, does not touch the hilum or mediastinum, and is not associated with adenopathy, atelectasis, or pleural effusion. A solitary pulmonary nodule is defined as a discrete lesion 3 cm in diameter that is completely surrounded by lung parenchyma (ie, does not touch the hilum, mediastinum, or pleura) and is without associated atelectasis or pleural effusion. They are based initially on identifying whether the nodule is solid or subsolid and then evaluating its size. Solitary noncalcified solid nodules measuring 6-8 mm in patients with low clinical risk are recommended to undergo initial follow-up at 6-12 months depending on size, morphology, and patient preference ( grade 1C: strong recommendation, low- or very-low-quality evidence).
