@entity1697 is a @entity1613 with high malignant potential, and resection is the recommended treatment. We designed a retrospective study to analyse the outcome of treatment in @entity1 who had operations for @entity1697 . A total of 84 @entity1 (74 @entity1 and 10 @entity1 , mean (SD) age 54 (12) years, range 29-83) were enrolled. Histopathologically the diagnoses were @entity189 (n=3), @entity1141 / @entity189 in situ (n=61), and @entity1373 (n=20), and all @entity1 were treated by @entity544 laser excision. There was no postoperative malignant transformation, but @entity189 found after initial excision (n=3) was treated by further radical excision. The mean (SD) follow-up period was 46 (29) months (range 1-124), The postoperative recurrent rate was 14/84 (16.7%). The @entity1697 was the only factor associated with @entity86 on univariate analysis, and was also the only independent factor that predicted @entity86 in multivariate logistic regression analysis. An area exceeding 80mm(2) had the best predictive value (sensitivity=0.71, specificity=0.67) with a 5.1 times increased risk (odds ratio=5.1, CI 95% 1.45 to 18.05, p=0.01) of recurrence. Laser excision is effective for @entity1697 that is still confined to @entity1141 of any degree, with low morbidity. The @entity1697 is a predictive factor for @entity86 .
