title: [Diagnosis and treatment of primary pulmonary mucosa-associated lymphoid tissue lymphoma].
abstract: OBJECTIVE
  To study the diagnosis and treatment for primary pulmonary mucosa-associated lymphoid tissue lymphoma.
  
  
  METHODS
  The clinical data of 12 patients with primary pulmonary mucosa-associated lymphoid tissue lymphoma from August 1992 to May 2005 were analyzed.
  
  
  RESULTS
  All the patients survived during the follow-up periods of 6 to 164 months (mean 70.3 months). Gastric mucosa-associated lymphoid tissue lymphoma was found to coexist in 2 patients. No specific symptoms or signs, or specific results of bronchoscopy, ultrasonography or bone marrow examination were found in these patients, except that radiography showed nodules with blurred margins with characteristic air bronchogram. The final diagnosis was based on histology and immunohistochemistry. Surgical resection was performed for 6 patients, including 5 radical operations and 1 partial resection, among which 4 patients received adjuvant chemotherapy. Recurrence occurred in 1 patient 12.7 years after the operation, while the other 5 patients got disease free survival. Chemotherapy alone was administered for 4 patients, among whom 2 patients got complete remission and the others got partial remission. The other 2 patients received no treatment and had survived for 6 and 26 months respectively.
  
  
  CONCLUSIONS
  Except for the radiographic findings, there were no specific clinical manifestations for primary pulmonary mucosa-associated lymphoid tissue lymphoma. The final diagnosis should be made by histology and immunohistochemistry. Surgery and chemotherapy can be adopted for the patients with good outcomes.
