[Consideration of the prognostic factors influencing survival after lung metastasectomy of XXXX ].

@entity1 @entity1358 @entity75 @entity3
From 1989 to 2002, 9 @entity1 with @entity1358 to lung underwent lung resections for curative removal of metastatic disease in our department. Disease free interval (DFI), number and size of @entity3 resected (at first metastasectomy), and number of metastasized regional lymph nodes were studied after resection of pulmonary @entity3 . DFI were 0 to 60 months with mean value of 23 months. At first operation, single @entity3 accounted for 4 cases and @entity75 more than 2 @entity3 accounted for 5 cases with mean value of 2.1. Maximal diameter of @entity3 was 10 to 50 mm with mean value of 24 mm. Regional lymph nodes @entity3 were demonstrated only 1 @entity1 in 2 of No. 12 lymph nodes adjacent to @entity3 . At subsequent relapse, 1 @entity1 had second-stage metastasectomy, 2 @entity1 went on to a third phase. Four @entity1 were lost, 2 are under treatment for newly relapsed lesions, and 3 are now free of @entity3 . Analysis was performed by Cox proportional hazards model of survival using these factors. Though lacking the statistical significance, only maximal diameter of @entity3 was prone to have influencing factor on prognosis. Survival was not related to DFI between 0 to 21 months and more than 21 months and numerous lung @entity3 between single metastasis and with 2 or more. In general, estimated survival rate of these @entity1 according to Kaplan-Meier was 0% at 67 months. Considering the above results, surgical treatment for @entity1 with @entity1358 to lung should be planned carefully.
