The role of intraoperative cytology in the diagnostic evaluation of ovarian neoplasms

Abstract

Objective: To determine the role of intraoperative cytology (IOC) in the diagnostic evaluation of ovarian neoplasms.

Methods: The present study was conducted in the Department of Pathology, Jawaharlal Nehru Medical College, AMU, Aligarh, India, over a time span of 18 months. Depending on the consistency of the lesion, touch, scrape or crush techniques were used to prepare cytological smears. Smears were fixed in 95% ethyl alcohol and then stained with hematoxylin and eosin or Papanicolaou stains. Cytological results were compared with the histological diagnosis taking the latter as the gold standard.

Results: Of 50 lesions studied by IOC, 25 lesions were labeled as benign, 24 lesions as malignant and 1 lesion was inconclusive. Final histological diagnoses labeled 25 lesions as benign and 25 lesions as malignant. Comparing the diagnosis of cytology smears with histology sections, 47 of 50 cases were concordant. Sensitivity, specificity and diagnostic accuracy were 95.8, 96.0 and 95.8%, respectively.

Conclusions: IOC is a good complement to histopathology in the study of ovarian neoplasms, particularly in developing countries like ours, where the facility of frozen sections is often not available, since a rapid preliminary diagnosis may help in surgical management planning.
