Wedge Resection Margin Distances and Residual Adenocarcinoma in Lobectomy Specimens

Abstract: We studied 31 T1 N0 M0 peripheral adenocarcinomas diagnosed by wedge resection and treated by lobectomy. Factors recorded were pleural surface-based, gross cut-surface, and microscopic margin distances; morphologic features of the adenocarcinomas; microscopic extension distance of beyond gross perimeter of neoplasm; and presence of residual adenocarcinoma in the lobectomy specimen. All staple-line margins in the wedge and lobectomy specimens underwent complete histologic examination. The mean pleural surface-b… Show more

“…The free resection margin width was defined as the shortest width between the tumor and the resection line. The gross cut‐surface margin width was measured [12]. Tumor size was also measured, and these data were recorded in the final reports of the histopathological examination.…”

“…It’s extremely important to define the pathological margin. The mean microscopic wedge resection margin distance was 11 mm smaller than the pleural surface-based margin [ 18 ]. We measured the pleural surface-based margin on a back table.…”

“…To date, studies specifically aimed at researching the level to which margins are involved in cancer management and tumor recurrence have demonstrated no significant difference between invasive or intra‐ductal cancer [29, 30]. However, they do suggest that the extension and anatomical location of the non‐negative margin may contribute to the LR rate [26, 31] and can help predict how effective radiotherapy will be [32].…”
