title: Role of hysterectomy and lymphadenectomy in the management of early-stage borderline ovarian tumors.
abstract: To examine survival of women with stage T1 borderline ovarian tumors (BOTs) stratified by hysterectomy and lymphadenectomy status at surgery.
  
  
  
  This is a retrospective study examining The Surveillance, Epidemiology, and End Results Program to identify surgically-treated stage T1 BOTs between 1988 and 2003 (n=4943). Association of surgery patterns and cause-specific survival (CSS) was examined in multivariable analysis.
  
  
  
  Mean age was 48.7. The majority had stage T1a disease (75.3%). Median follow-up was 15.6years and 159 (3.2%) women died of BOTs. Hysterectomy and lymphadenectomy were performed in 1909 (38.6%) and 1295 (26.2%) cases, respectively. Most commonly, neither procedure was performed (46.5%), followed by hysterectomy alone (27.3%), lymphadenectomy alone (14.9%), and both procedures (11.3%). Surgery patterns for hysterectomy and lymphadenectomy significantly differed across age, ethnicity, marital status, registry area, year at diagnosis, histology type, sub-stage, and tumor size (all, P<0.001). On multivariable analysis, surgery patterns for hysterectomy and lymphadenectomy were not associated with CSS: 20-year rates for neither hysterectomy and lymphadenectomy 96.7%, hysterectomy alone 94.5%, lymphadenectomy alone 95.7%, and both procedures 95.2% (adjusted-P>0.05). Age≥50, T1b-c stages, and mucinous histology remained independent prognostic factors for decreased CSS (all, P<0.05). Among 3723 women with stage T1a disease, hysterectomy and lymphadenectomy patterns were not associated with CSS in 2115 women aged <50 (P=0.14) and 1608 women aged ≥50 (P=0.48).
  
  
  
  Our study suggests that both hysterectomy and lymphadenectomy may be omitted in the surgical management of women with stage T1 BOTs, especially for those with T1a disease regardless of age.
