Abstract
We report here in two patients who successfully underwent limited surgery for the treatment of bilateral pulmonary mucosa-associated lymphoid tissue (MALT) lymphoma. The patients were a woman in her 40s and a man in his 70s, with both having no symptoms. We could not diagnose them definitely before surgery, and confirmed MALT lymphoma via intraoperative lung biopsy. Lymphomas were completely resected with a combination of partial resection and segmentectomy of the lung in the two cases. These patients received no postoperative adjuvant therapy and, at present, are alive without recurrence. Although surgical, chemotherapeutic, or radiation therapy has been reported for the treatment of pulmonary MALT lymphoma, there are no established regimens and the operative method like as the standard operation for lung cancer. To date, few reports concerning the long-term prognosis of patients with pulmonary MALT lymphoma have been published in Japan. It is important to perform long-term follow-up studies of such patients to confirm what kind of treatment for pulmonary MALT lymphoma is suitable.
