Invasive Mediastinal Staging Guideline Concordance.

摘要: Background Despite guidelines for preoperative invasive mediastinal staging (IMS) non-small cell lung cancer (NSCLC), concordance with and whether the use of these results in expected frequency lymph node metastases has not been evaluated. Our objectives were to determine guideline concordance, reasons nonconcordance, and, patients who did receive IMS, operative nodal sampling final pathologic staging. Methods Patients had a resection NSCLC between 2010 2012 identified from Institutional Cancer Registry. A chart audit was performed adherence Care Ontario (CCO) IMS criteria, reports reviewed postresection Results Of 242 resections study period 102 (42%) IMS. 66 (65%) did not require based on CCO thus concordant guidelines, whereas 36 (36%) nonconcordant. have only 72 intraoperative assessment 35 (34%) three or more ipsilateral (N2) stations. In group, 2 (5%) positive N2 nodes, nonconcordant group 3 (11%) positive. Conclusions Although overall used 140 (58%), high at 85% (206 patients). However, rates non-IMS cases (both nonconcordant) lower than expected, resulting potentially understaged patients.
