Objective: Ovarian needle aspiration and biopsy (ONAB) may be employed for pretreatmentdiagnosis of ovarian malignancies or intraoperatively to facilitate removal of ovarian masses. However, there is reluctance to utilize this procedure due to potential cyst rupture or seedingof malignant cells. The objective of this study was to examine the efficacy of ONAB over a 13-year period at our institution. Methods: Between 2000 and 2013, all ONAB specimens were identified from the Queen'sMedical Center Pathology Department database. All cytologic specimens were reviewedand correlated with histopathologic findings. A retrospective chart review was conducted toretrieve data on clinical course and treatment. Results: This study identified 144 cases of ovarian masses sampled by aspiration or needlebiopsy between 2000 and 2013. Ninety-two (64%) cases had corresponding histopathology,84 (91%) of which were obtained concomitantly. On histology, 12 (13%) cases were malignantand 80 (87%) benign. Three false negative cases were noted; 2 serous borderline tumors and1 mucinous cystadenocarcinoma. These were sampling errors; no diagnostic tumor cells werepresent in the aspirates. Sensitivity and specificity of ONAB in the detection of malignancywere 75% and 100%, respectively. The positive and negative predictive values were 100% and96%, respectively. Conclusion: ONAB represents a valuable tool in the diagnosis of malignancy and treatmentof ovarian masses. In our study, it was highly specific, with excellent positive and negativepredictive value.
