National trends in the surgical staging of corpus cancer: A pattern-of-practice survey

Objective: To survey general gynecologists regarding the nature of surgical staging of corpus cancer as practiced in the United States. Methods: A survey tool was designed to ascertain issues related to surgical staging of corpus cancer among gynecologists in the United States. The survey elicited data pertaining to the demographics and practice characteristics of the respondents. The questionnaire was sent to 700 practicing gynecologists selected randomly from the ACOG membership list. Results: Responses were obtained from 227 physicians; however, only 193 could be analyzed. Most of the respondents classified themselves as general gynecologists (93%) and nonacademicians (90%). In a typical year, 60% evaluated fewer than Eve patients with corpus cancer. A minority of respondents carry out surgical staging of their patients, which includes total abdominal hysterectomy and bilateral salpingo-oophorectomy (TAHBSO), removal of pelvic and para-aortic lymph nodes, and cytologic evaluation of peritoneal fluid. No uniformity was observed regarding the numeric definition of an appropriate ''sampling'' (median 5, range 1-25) or ''dissection'' (median 10, range 1-40) of lymph nodes. Most respondents would not return a corpus cancer patient to the operating room to carry out lymph node dissection if a referring colleague had performed TAHBSO but had not removed the nodes. In such a scenario, private practitioners were approximately three times less likely to reoperate on lymph nodes than academic physicians. Conclusion: Complete surgical staging is not performed by most physicians caring for women with corpus cancer. The relatively high proportion of nonresponders and nonevaluable responses suggests that these results should be corroborated by other investigators.
