[Evaluation of lymph node metastasis in the contralateral mediastinum or scalene through mediastinoscopy and para-mediastinal small incision in potentially operable non-small cell lung cancer].
The purpose of this study was to investigate the clinical characteristics of lymph node metastasis in the contralateral mediastinum and scalene in patients with potentially operable nonsmall cell lung cancer (NSCLC). ⋯ Biopsy of contralateral mediastinal lymph nodes or scalene lymph node should be performed in order to exclude N3 disease for potentially operable NSCLC patients with adenocarcinoma, serum CEA >5 ng/ml or ipsilateral multi-station mediastinal lymph node metastasis.

[Influence of number of removed lymph nodes on the TNM staging and survival in advanced esophageal carcinoma].
To evaluate the impact of total number of removed regional lymph nodes (LN) during esophagectomy on TNM staging and long-term survival. ⋯ A large series of retrospective study on advanced squamous cell carcinoma of the thoracic esophagus demonstrates that the number of metastatic LN is an important prognostic factor, therefore, it should be considered when refining UICC-TNM classification for esophageal cancer. If the total number of LN removed during each esophagectomy is less than 6, the occult positive regional LN might be missed, resulting in an inaccurate N classification and incorrect staging. Removal of > or = LN for each esophageal cancer patient during esophagectomy recommended by UICC is rational and should be complied with.
