title: Borderline epithelial tumours of the ovary--a retrospective analysis of 31 cases.
abstract: Thirty one cases of epithelial borderline tumours of the ovary recorded over a period of six years were reviewed. The incidence of borderline tumours was 6% in relation to ovarian epithelial malignancies, with serous and mucinous types comprising three fourth of the lesions. The serous tumours were bilateral in 39%, revealed surface growth in 17% and had peritoneal implants in 11% of cases. The mucinous tumours were bilateral in 11% and had associated pseudomyxoma peritonei in 22% of cases. Nuclear grade appeared to correlate with extraovarian spread and surface growth in the serous borderline tumours, but not in the mucinous borderline tumours. The endometrioid borderline tumours and mixed epithelial borderline tumours were rare lesions. Twenty one patients (68%) presented in Stage-la. Surface growth correlated with recurrences. The prognosis remained good in serous borderline tumours even in the presence of implants as these were non-invasive. The mean disease free survival was 43.03 months. There was no statistical difference in disease free survival of patients with and without implants.
