      Background:
      The rate of mediastinal lymph node metastasis is controversial for patients with clinical N0 non-small cell lung cancer. The primary advantage of video-assisted mediastinoscopic lymphadenectomy(VAMLA) over conventional mediastinoscopy or videomediastinoscopy is to reduce the false-negative rate. We aimed to analyze to evaluate the value of routine VAMLA for patients with clinical T1a-T2aN0 patients prospectively.

      Methods:
      From March 2010-January 2015, 41 patients with non-small cell lung cancer with clinical stage T1-T2aN0 by postireon emission tomography/computed tomography underwent routine VAMLA before planned resectional surgery.Routinely, stations #2L, 2R, #4R, #4L, 7 were nearly completely resected. In some patients, #10R and #8 lymph nodes were biopsied. The prevalence of mediastinal lymph node metastases at VAMLA and lung resection was recorded.

      Results:
      There were 5 females (12.2%) and 36 (87.8%) males. The mean age was 62.5 . years. A total of 5 patients were had cT1a-bN0, whereas 36 patients had T2aN0. Eleven patients (26.8%) had occult mediastinal lymph node metastasis. A total of 26 patients underwent lung resectional surgery; only one patient (3.8%) were upstaged to pN2, whereas 3 patients (11.5%) were upstaged to pN1.

      Conclusion:
      VAMLA seems to disclose considerable number of mediastinal lymph node metastasis in these patients with T1 and T2 clinically staged N0 by positron emission tomography/computed tomography. Routine use of VAMLA is recommended with limited use of mediastinal lymph node evaluation in patients during resectional surgery.
