In @entity5 , recurrence is not uncommon but prognostic factors in recurrent @entity704 have not been determined and standardized treatment for recurrence has not yet been established. A retrospective analysis was conducted on 24 @entity704 @entity1 who underwent treatment for recurrence in our institution to determine the prognostic factors for overall survival. Recurrence of @entity704 appeared 11.6-109.6 months after the primary operation (34.6  25.7 months). Pleural disseminated recurrence was common (n=21) as the primary recurrent lesions. Single or combined modality therapy was performed in 19 @entity1 ; surgical resection in 12, radiotherapy in 10, and chemotherapy in six @entity1 . A third surgical resection was performed in two @entity1 . There was no difference in overall survival between the groups with or without treatment nor in those with or without resection. Old age and chemotherapy were factors for poorer prognosis. @entity1 with one or two recurrent lesions detected on CT examinations showed better prognosis. Prognosis in @entity704 @entity1 with recurrence was reviewed in the present study. @entity1 with a small number of recurrent lesions showed better prognosis irrespective of the treatment.

Number of recurrent lesions is a prognostic factor in recurrent XXXX .
