title: Breast cancer metastatic to abdomen and pelvis: role of surgical resection.
abstract: OBJECTIVE
  The purpose of this study was to describe the characteristics and outcome of women with metastatic breast cancer to the abdomen and pelvis, and to assess the role of surgical resection of abdominal and pelvic metastasis in this disease.
  
  
  METHODS
  We retrospectively reviewed the medical records of 59 women with documented metastatic breast cancer to the abdomen or pelvis who had exploratory surgery by the Gynecology Service between 1986 and 2001.
  
  
  RESULTS
  Exploratory surgery was performed a median of 5 years (range, 0-25 years) after initial diagnosis of breast cancer. Median survival from diagnosis of abdominal disease was 23 months, and 5-year survival was 24%. Survival was 36 months for optimally debulked patients (<2 cm of residual disease) and 20 months for suboptimally debulked patients (P = 0.07). Patients diagnosed 5 or more years after initial breast cancer diagnosis had a median survival of 36 months versus 17 months if diagnosed earlier (P < 0.01). On multivariate analysis the time to recurrence of breast cancer in the abdomen and optimal debulking were both significant variables. Hazard ratio for dying of disease if recurring before 5 years was 2.7 (CI 1.45-5.03) [P < 0.01]. Hazard ratio for dying of disease if suboptimal debulking was achieved was 2.14 (CI 1.13-4.02) [P = 0.02].
  
  
  CONCLUSIONS
  The disease pattern of metastatic breast carcinoma to the abdomen and pelvis does not appear to effect survival. Survival in patients where optimal debulking is achieved and in those recurring late is improved. Surgical resection of metachronous metastatic breast cancer to the abdomen and pelvis may be an important component of the management of this disease and should be considered in candidate patients.
