PURPOSE: Although segmentectomy is attempted for small @entity1149 ( @entity1149 ) @entity5 , no reports have so far described how many of these @entity5 can be candidates for a successful resection by single segmentectomy. METHODS: In all, 135 @entity1 with peripheral p-T1N0M0 @entity1149 were examined. The @entity5 were classified into five groups divided by every 0.5-cm increase in size. @entity5 locations were classified into two groups - limited to within one segment and extended beyond one segment - based on the identification of whether pulmonary vessels and the bronchi were involved in the @entity5 on high-resolution computed tomography. Differences in the proportion of @entity5 limited within one segment between @entity5 smaller and larger than each class of @entity5 size were assessed. RESULTS: The @entity5 sizes were 0-1.0 cm in 8 @entity5 , 1.1-1.5 cm in 27, 1.6-2.0 cm in 35, 2.1-2.5 cm in 34, and 2.6-3.0 cm in 31 @entity5 . Of these 135 @entity5 , 92 (65%) were limited to one segment, whereas 48 (35%) had extended beyond one segment. When the @entity5 size was less than 30 mm, the proportion of @entity5 limited within one segment did not show any significant difference depending on the size of the @entity5 . CONCLUSIONS: More than one-third of p-T1N0M0 @entity1149 extended beyond one segment, irrespective of size. It is therefore noteworthy that resection of up to two segments or lobectomy should be undertaken for prevention of local recurrence in @entity1 with p-T1N0M0 peripheral @entity1149 .

How many pathological T1N0M0 XXXX can be completely resected in one segment? Special reference to high-resolution computed tomography findings.
