Postoperative adjuvant radiotherapy for XXXX of the @entity135 : treatment results and prognostic factors.

@entity1 @entity135 @entity5 @entity2347 @entity3
BACKGROUND: To analyze the treatment results and prognostic factors of @entity1 with @entity2347 ( @entity2347 ) arising from the major and minor salivary glands of the @entity135 , and who received postoperative radiotherapy after radical @entity5 resection. METHODS: Between October 1987 and December 1999, 25 @entity1 with @entity2347 of the @entity135 were treated with radical surgical resection and postoperative adjuvant irradiation without chemotherapy. Using appropriate radiation techniques to the @entity5 bed, total doses ranged from 44 to 68.4 Gy. All @entity1 had a minimum of 2 years of follow-up. RESULTS: The 5-year overall survival rate, local control rate, and distant @entity3 -free rate were 75%, 83%, and 66%, respectively. To the present, 2 @entity1 had experienced recurrence at the primary sites, and 1 had regional lymph node @entity3 . Distant metastases developed in 7 @entity1 (28%), of whom 6 (86%) were disease-free at the primary site. The lung was the most common distant metastatic site. In multivariate analysis, the only statistically significant prognostic factor for a distant @entity3 -free rate was the stage at presentation (p = 0.009). CONCLUSION: @entity1 with an advanced stage of disease had higher distant @entity3 rates even when receiving postoperative radiotherapy. Distant @entity3 is still the main problem in the management of @entity2347 of the @entity135 . However, more-effective treatment for this problem is still lacking.
