Importance of Routine Mediastinal Staging in Women With Nonsmall Cell Lung Cancer

Objective TO study the specific importance of mediastinal staging in women with nonsmall cell lung cancer. Patients and methods Between July 1981 and September 2003 we surgically staged 2172 patients with nonsmall cell lung cancer who met the inclusion criteria for resectability and operability. A subgroup of 108 women was studied. Cervical mediastinoscopy was performed in all cases, with the addition of anterior mediastinotomy in cases with left upper lobe involvement. All patients underwent a preoperative computed tomography chest scan. Results Cervical mediastinoscopy was performed on all 108 patients, 26 of whom also underwent anterior mediastinotomy. Positive findings were recorded in 44 (40.7%) of the 108 cases: 39 of the 108 mediastinoscopies (36.1%), 9 of the 26 mediastinotomies (34.6%), and in 5 cases (19.2%) both mediastinoscopy and mediastinotomy. Nodal involvement was found in 13% of cases in clinical stage IA and 30.8% of cases in clinical stage IB. The percentage of positive findings was significantly higher for cases with adenocarcinoma or large cell carcinoma ( P Conclusions Routine mediastinoscopy is indicated for all women with nonsmall cell lung cancer, regardless of clinical stage.
