title: [Long-term outcome of 52 patients with chronic periaortitis treated with steroids, immunosuppressive therapy and(or) tamoxifen.].
abstract: OBJECTIVE
  The study aims to assess the therapeutic benefit of medicine treatment in chronic periaortitis.
  
  
  METHODS
  A retrospective study of 52 patients with chronic periaortitis treated at Peking Union Medical College Hospital. Summarize clinical features, level of acute-phase reactants, extent of ureteral obstruction, level of renal function, size of mass with repeated follow-up CT scanning during the period of therapy.
  
  
  RESULTS
  The most prominent symtom was back or abdominal pain. 76.92% had ureteral obstruction, with 26.92% had a progressive renal failure. After a period of treatment, 95.35% were significant to complete resolution of symptoms. There was also a remarkable decrease in ESR and C-reactive protein a median treatment of 4 weeks. Creatinine decreased significantly (P = 0.002) in patients with progressive renal failure. 66.67% was successfully removed the ureteric stents. CT scanning showed 75% mass regression after a median of 6 months.
  
  
  CONCLUSIONS
  The clinical manifestations of chronic periaortitis is nonspecific, which often leads to a delayed diagnosis and the late complications. Chronic periaortitis is very effectively treated by a combination of steroids and immunosuppressive therapy and(or) tamoxifen, with excellent long-term outcome and relatively fewer disease relapse.
