Ovarian tumor of low malignant potential

Abstract

OBJECTIVE: To determine the clinical, diagnostic and surgicopatbological aspects of ovarian tumors of low malignant potencial or borderline malignancy. MATERIAL AND METHODS: 12 cases of ovarian tumors of LMP are reviewed at Guillermo Almenara Hospital (1990-1997). These tumors constitute 11 896 of all ovarian cancer. The average age of the patients was 42,5 years, one decade earlier than the mean age at diagnosis for invasive ovarian cancer. Pelvic tumor and pain were predominant characteristics. Average greatest diameter was 21 cm; 83,3% (p < 0,001) of these tumors bad complex ecoestructure (thick or thin wall, septae, and some internal ecos). CA-125 tumor marker was determined in 5 cases, and all bad <35 U/mL levels. All tumors were epithelials, and the majority mucinous 83,3%. FIGO's stages were stage I, 8,3% stage II, and 16,6% stage III (p>0,05). Management was according in to ovarian cancerprotocols in 10/12 cases. Second look was negative in 414. CONCLUSIONS: All ovarian tumors of LMP were epithelial in origin. The mucinous tumors were predominant, 83,3%. Only 16,6% had simple ecoestructure. In 515 cases, CA-125 was < 35 U/mL. 5. Almost all, 83,3% had management similar to ovarian cancer protocols. Second look was negative in 4/4 cases.
