Comparison of clinical and functional outcome between surgical treatment and @entity505 ion radiotherapy for pelvic XXXX .

@entity1 @entity505 @entity511
BACKGROUND: As there are no reports of studies in @entity1 with pelvic @entity511 treated with @entity505 ion radiotherapy (CIRT), the aim of this study was to evaluate the applicability of CIRT for @entity1 with @entity511 . METHODS: The medical records of 31 @entity1 with @entity511 treated either by surgical resection or by CIRT between 1983 and 2014 were reviewed. There were 22 males and 9 females with a median age of 43  years (range 16-77  years). The median duration of follow-up was 66  months (range 5-289  months). Twenty-four @entity1 underwent surgery, and 7 @entity1 received CIRT (70.4  GyE in 16 fractions over 4  weeks). RESULTS: The overall local recurrence rate was 32  %, and the estimated overall 5- and 10-year survival rates were 72 and 57  %, respectively. The mean Musculoskeletal Tumor Society functional score was 59  %. The treatment procedures (surgery or CIRT) did not affect overall survival (P  =  0.347). However, the @entity1 who underwent surgery had impaired function compared with those who received CIRT (P  =  0.03). CONCLUSION: Although more @entity1 need to be monitored to assess the clinical and functional outcomes of CIRT for @entity1 with @entity511 , this treatment might offer an acceptable alternative.
