Purpose The purpose of this study was to determine how physician experts make decisions for clinical scenarios in ovarian cancer and describe a profile of factors reported to influence treatment decisions.

Methods A questionnaire was sent to Full Members of the Society of Gynecologic Oncologists regarding surgery and chemotherapy for scenarios of primary and recurrent ovarian cancer.

Results In a scenario of primary presentation, 94% of respondents chose a treatment of tumor resection over chemotherapy. Despite the preference for surgery in a clinical scenario, 50% agreed with a statement that neoadjuvant chemotherapy is equivalent to primary surgery. In a scenario of recurrent disease, a comparable number of respondents chose a treatment of secondary cytoreductive surgery (45%) versus direct retreatment with chemotherapy (49%). Those choosing surgery responded that they believed in extensive surgery to achieve optimal cytoreduction. Most (62%) respondents described themselves as collaborative in treatment planning, yet only 24% reported that patient preference strongly influences their decision making.

Conclusions Although a plan for primary cytoreduction is favored, in specific scenarios, views were divided for the role of neoadjuvant chemotherapy. For a recurrent disease scenario, support was divided between secondary cytoreductive surgery and direct retreatment with chemotherapy. Further clinical research is necessary to minimize the discordance between physician beliefs and recommendations.
