Patterns of local recurrence in XXXX : a single-center experience.

@entity1 @entity5 @entity1600 @entity189 @entity348
A cohort of @entity1 operated at the National @entity5 Center Hospital in Tokyo for @entity189 , at or below the peritoneal reflection, was reviewed retrospectively. The purpose was to study the risk factors for local relapse and the patterns of local recurrence. Three hundred fifty-one @entity1 operated between 1993 and 2002 for @entity189 , at or below the peritoneal reflection, were analyzed. One hundred forty-five @entity1 , with preoperatively staged T1 or T2 @entity5 without suspected lymph nodes, underwent @entity348 ( @entity348 ). @entity1600 ( @entity1600 ) was performed in suspected T3 or T4 disease, or when positive lymph nodes were seen; 73 @entity1 received unilateral @entity1600 and 133 @entity1 received bilateral @entity1600 . Of the 351 @entity1 6.6% developed local recurrence after 5 years. @entity348 only resulted in 0.8% 5-year local recurrence. In lymph-node-positive @entity1 , 33% of the unilateral @entity1600 group had local relapse, significantly more (p = 0.04) than in the bilateral @entity1600 group with 14% local recurrence. Local recurrence in the lateral, presacral, perineal, and anastomotic subsites was lower in the bilateral @entity1600 group as compared with in the unilateral @entity1600 group. We conclude that, in selected @entity1 , surgery without @entity1600 has a very low local recurrence rate. Bilateral @entity1600 is more effective in reducing the chance of local recurrence than unilateral @entity1600 . Either surgical approach, with or without @entity1600 , requires reliable imaging during work-up.
