Is there a role for curative surgery for pelvic recurrence from rectal carcinoma in the presence of hydronephrosis?
BACKGROUND
The prognosis for patients with recurrent rectal adenocarcinoma is not uniformly fatal if one can safely and selectively reoperate on a subset of patients with resectable disease. Even with careful selection, many patients undergo exploratory laparotomy and do not have resectable disease. We have reported that the presence of hydronephrosis in the setting of recurrent rectal carcinoma portends a poor outcome because of invariable association with unresectable disease. The purpose of this study was to update our experience of patients presenting with unilateral or bilateral hydronephrosis and recurrent rectal cancer.


METHODS
A retrospective chart review of 142 patients with recurrent rectal cancer evaluated at our institution from January 1989 to December 1999 was performed.


RESULTS
Twenty-seven of 142 patients referred for the management of recurrent rectal cancer had unilateral or bilateral hydronephrosis. Fifteen (55%) of these patients had distant metastatic disease. Twelve patients (45%) with hydronephrosis and local recurrent disease on evaluation were analyzed. Six of the 12 patients underwent exploratory laparotomy, with none found to have resectable disease. Their mean survival after diagnosis of recurrent disease was 14 months.


CONCLUSIONS
Based on our results, the presence of hydronephrosis (unilateral or bilateral) in recurrent rectal adenocarcinoma portends a survival equivalent to the presence of distant metastasis. Therefore, we do not believe potential curative surgery has a role for patients with locally recurrent rectal adenocarcinoma in the presence of hydronephrosis.
