Analysis of recurrence risks for @entity44 in XXXX .

@entity1 @entity5 @entity44
BACKGROUND/PURPOSE: The purpose of this study was to investigate effects of risk factors on recurrence of @entity44 ( @entity44 ). METHODS: A retrospective review was conducted of 107 SCTs treated between January 2003 and December 2012 in our center. Risk factors were identified by univariate and multivariate analysis. RESULTS: Sixteen @entity1 had recurrence of @entity44 a median interval of 16.25months after primary surgery. 15.6% @entity5 recurrence were Altman type I, 10.5% type II, 10.0% type III, and 31.3% type IV. The recurrence of mature @entity44 was observed in 8 @entity1 , immature in 2, malignant in 5. More than half of the recurrences showed a shift towards histological immaturity or @entity5 , compared with the @entity5 pathology. Risk factors for recurrence were spillage of @entity5 parenchyma during operation (P=0.028), incomplete resection (p=0.000), and primary immature (P=0.029) and malignant histology (P=0.026). Size, Altman classification, and age were not risk factors for recurrence. There was a statistically significant difference in OS between @entity1 who developed relapse (64.8%) and those who did not (95.0%) (P=0.0002). CONCLUSIONS: @entity5 recurrence affected the outcome of @entity1 with @entity44 . Risk factors were @entity5 spillage, immature and malignant histology, or incomplete resection. Regular follow-up after surgery is mandatory to find @entity5 relapse earlier and to improve the outcome.
