title: [Clinicopathologic features and prognosis of lymphoepithelioma-like carcinoma of the lung].
abstract: OBJECTIVE
  To analyze the clinicopathologic features and prognosis of lymphoepithelioma-like carcinoma (LELC) of the lung.
  
  
  METHODS
  26 cases of pulmonary LELC with available long-term follow-up information were compared with 84 cases of pulmonary non-LELC(33 cases of squamous cell carcinoma, 36 cases of adenocarcinoma, 6 cases of adeno-squamous carcinoma and 9 cases of large cell carcinoma) with available long-term follow-up information using Kaplan-Meier method and the generalized Wilcoxon test.
  
  
  RESULTS
  LELC of the lung had a better prognosis than non-LELC (P < 0.05). Further study showed that pulmonary LELC had a significantly better prognosis than adeno-squamous carcinoma and large cell carcinoma. However, there was no significant prognostic differences between pulmonary LELC and squamous cell carcinoma and adenocarcinoma. Tumor recurrence and necrosis (> or = 5% of tumor) were associated with poor prognosis.
  
  
  CONCLUSIONS
  Pulmonary LELC, which is a very rare and unique entity, has a better prognosis after therapy.
