Randomized Controlled Trial Comparative Study Clinical Trial[Evaluation of staging conformity CTNM and PTNM for lung cancer].
A series of 225 consecutive lung cancer patients were prospectively randomized into study group (75 patients) and control group (150 patients), and the conformity of CTNM and PTNM staging was was evaluated. Radical mediastinal lymph node dissection was performed and in average 11.5 nodes were dissected in the study group. Only suspected metastatic lymph nodes, 3.4 in average, were dissected in the control group. ⋯ The results of the study show that at present the CTNM staging has not fully satisfied the needs of practice and requires to be further improved. The operative procedure which only dissects suspected involved mediastinal lymph nodes can not meet the needs of PTNM staging. In order to make PTNM staging accurately and evaluate the results of treatment for lung cancer, radical mediastinal lymph node dissection should be performed in every operable patient.
