title: Successful Chemo-Radiotherapy for Primary Anaplastic Large Cell Lymphoma of the Lung: A Case Report and Literature Review.
abstract: BACKGROUND
  Primary anaplastic large cell lymphoma (ALCL) of the lung is an extremely rare disease. This disease is a great challenge for pneumologists due to its nonspecific clinical presentations and radiological findings. Appropriate invasive biopsy and immunohistochemistry are important for diagnosis. There is currently no standard treatment.
  
  
  METHODS
  We report a very rare case of primary pulmonary ALCL in a 39-year-old man. The clinical features, imaging, pathological findings, treatment outcomes, and prognosis, are described. Successful treatment outcomes were achieved after 6 cycles of CHOP (cyclophosphamide, doxorubicin, vincristine, and prednisone) chemotherapy followed by involved field radiotherapy of 54 Gy/27f. The patient was disease-free after follow-up for 65 months.
  
  
  CONCLUSIONS
  Our study found that chemotherapy (such as CHOP) is recognized as the first-line regimen for primary ALCL of the lung. For patients with dyspnea caused by a mass blocking the main bronchus, chemo-radiotherapy may be a reasonable therapeutic option. The prognosis is better for patients with positive ALK staining. CD56(+), age older than 60 years, Ann Arbor stage III or IV, survivin expression, PS>2, and high serum LDH level and IPI scores are the poor prognostic factors of ALCL.
