PURPOSE: We investigated the surgical outcomes of clinical-T1b @entity2220 @entity1 whose @entity5 had a solid-dominant radiological appearance and who were treated with segmentectomy or lobectomy. METHODS: We examined 154 surgically resected clinical-T1b @entity2220 with a "solid-dominant" appearance on thin-section computed tomography (CT). The preoperative thin-section CT images of all cases were reviewed. "Solid-dominant" was defined as 0.5 <= consolidation/ @entity5 ratio (CTR) <1.0. RESULTS: Pathological nodal metastasis, lymphatic invasion, @entity1350 , and @entity3 were found in 7 (4.5  %), 27 (18  %), 21 (14  %), and 15 (10  %) @entity1 with clinical-T1b solid-dominant @entity2220 , respectively. Lobectomy and segmentectomy were performed in 123 (80  %) and 31 (20  %) cases, respectively. The 3-year @entity1349 ( @entity1349 ) and @entity4557 ( @entity4557 ) of @entity1 with clinical-T1b solid-dominant @entity2220 were 95.5 and 92.4  %, respectively. The 3-year @entity4557 and @entity1349 did not differ significantly between the @entity1 who underwent lobectomy or segmentectomy (3-year @entity4557 , 92.3 vs. 93.4  %, p  =  0.8713; 3-year @entity1349 , 95.3 vs. 96.6  %, p  =  0.7603). Segmentectomy was not found to be a prognostic factor for @entity4557 (p  =  0.8714), or @entity1349 (p  =  0.7613). CONCLUSIONS: Segmentectomy can achieve acceptable oncological outcomes (both in terms of @entity1349 and @entity4557 ), which are similar to those achieved with standard lobectomy, in @entity1 with clinical-T1b solid-dominant @entity2220 .
