“…1) of which 81 fit the inclusion and exclusion criteria. Among the 81 articles, 11 articles did not report on PSNs [19, 21–30], 2 did not include surgically resected cases [31, 32], 13 did not report DFS, lung cancer-specific-survival, or overall survival [33–45], 9 articles reported only on recurrence/death [13, 46–53], and 10 articles were conference abstracts with insufficient data. This left 36 articles reporting on 31 unique studies (Table 1).…”

“…Distinguishing between PSNs and solid nodules with only one CT scan may be difficult, particularly for solid nodules as they may be surrounded by a thin rim of haziness (i.e., nonsolid component). Thus, when progression from an NSN to PSN or solid nodule cannot be confirmed on thin-section CT scans; upper limits of the solid component of PSNs should be used to avoid misclassifying a solid nodule as a PSN [4, 5, 19, 20]. Examples of such misclassifications have been reported, leading to misunderstanding of the cell types that manifest as PSNs and their survival rates [5].…”

Purpose Summarise survival of patients with resected lung cancers manifesting as part-solid nodules (PSNs). Methods PubMed/MEDLINE and EMBASE databases were searched for all studies/clinical trials on CT-detected lung cancer in English before 21 December 2015 to identify surgically resected lung cancers manifesting as PSNs. Outcome measures were lung cancer-specific survival (LCS), overall survival (OS), or disease-free survival (DFS). All PSNs were classified by the percentage of solid component to the entire nodule diameter into category PSNs <80% or category PSNs ≥80%. Results Twenty studies reported on PSNs <80%: 7 reported DFS and 2 OS of 100%, 6 DFS 96.3-98.7%, and 11 OS 94.7-98.9% (median DFS 100% and OS 97.5%). Twenty-seven studies reported on PSNs ≥80%: 1 DFS and 2 OS of 100%, 19 DFS 48.0%-98.0% (median 82.6%), and 16 reported OS 43.0%-98.0% (median DFS 82.6%, OS 85.5%). Both DFS and OS were always higher for PSNs <80%. Conclusion A clear definition of the upper limit of solid component of a PSN is needed to avoid misclassification because cell-types and outcomes are different for PSN and solid nodules. The workup should be based on the size of the solid component.

“…In recent studies, sublobar resection has shown equivalent oncological results and survival outcome compared with lobectomy (25)(26)(27). Moreover, in 2010, Sugi and colleagues reported a retrospective study of 159 patients, revealing that there were no significant differences among the wedge resection, segmentectomy, and lobectomy approaches in the treatment of small NSCLC (28). Therefore, a limited resection is considered more appropriate in specific patients, such as those with small lung lesions, elderly patients, or those at a high risk of comorbidity.…”
