Hypothesis: Higher risk of malignancy index (RMI) with multidisciplinary approach will reduce the number of referrals of ovarian masses, thus reducing the stress for patients and workload at the cancer center.
Methods: Prospective observational study in which all patients with pelvic masses and an RMI lower than 450 were treated at the local hospital after discussion at multidisciplinary input. Patients with an RMI higher than 450 were referred to tertiary cancer centers. Records of multidisciplinary meetings, operative details, and histologic examination results were evaluated. Data were analyzed to calculate the predictive values and the sensitivity of this approach.
Results: If the RMI cutoff of 450 alone is considered, 1 woman with invasive cancer would not have been referred. The sensitivity for invasive epithelial ovarian cancer was 96.2% or 25 of 26 patients (95% confidence interval [CI], 80.4-99.9) with a positive predictive value of 96.3% or 26 of 27 patients (95% CI, 81.0-99.9). The specificity was 98.7% or 77 of 78 patients (95% CI, 93.1-100.0). The negative predictive value was 98.7% or 76 of 77 patients (95% CI, 93.0-100.0).
Conclusions: A higher RMI with multidisciplinary approach to refer patients with pelvic masses has the potential to reduce the numbers of benign cases, thus reducing stress for patients and reducing workload at centers.
