Ovarian cancer is the twelfth leading cause of cancer death in the United States. Based on data from SEER 18 2006-2012, the overall five-year survival rate is 46.2% and for distant and unstaged disease it is only 24-28% (SEER 2016; Kosary 2007). The…

• Proportion of patients with at least one evaluable FR+ ovarian cancer lesion confirmed by central pathology (Standard of truth) that was detected using the combination of OTL38 and fluorescent light but not under normal light or palpation. All evaluable FR+ ovarian cancer lesions that were identified prior to or after surgery, that were detected using the combination of OTL38 and fluorescent light but not under normal light or palpation, and were removed based on the evaluation under fluorescent light, will be included in the calculation of the proportion of patients with at least one FR+ ovarian cancer lesion confirmed by central pathology. The primary endpoint will be determined based on evaluable lesions as described below.
• Evaluable lesions are defined as follows: lesions that do not appear on an organ or tissue that was intended for removal based on the Pre-Fluorescence Surgical Plan, regardless of the absence or presence of tumor.
Achtergrond van het onderzoek
Ovarian cancer is the twelfth leading cause of cancer death in the United States. Based on data from SEER 18 2006-2012, the overall five-year survival rate is 46.2% and for distant and unstaged disease it is only 24-28% (SEER 2016; Kosary 2007). The standard management of primary ovarian cancer is optimal cytoreductive surgery (usually defined as reduction of residual disease to less than 1 to 2 cm) followed by chemotherapy (Al Rawahi 2013). Experts are advocating complete cytoreductive surgery for tumor debulking as it results in better overall
survival than optimal cytoreduction (Shih 2010). Although tumor debulking surgery is the cornerstone of current treatment in patients, the lesions can be diffuse and numerous, of various sizes, and often not readily visible in the surgical field, leading to varying rates of optimal cytoreduction among surgeons (Ibeanu 2010). This is an
important factor in the poor prognosis for patients with advanced ovarian cancer. Tumor-specific intraoperative fluorescence imaging may improve staging and debulking efforts in cytoreductive surgery.
