[Borderline tumors of the ovary: a multicenter study in 137 patients]. / Tumeurs borderline de l'ovaire: Etude multicentrique a propos de 137 patientes.

OBJECTIVES: Evaluate management of patients with a borderline ovarian tumor. MATERIALS AND METHODS: A multicentric retrospective survey was conducted in 137 patients with borderline ovarian tumor diagnosed between January 1, 19975 and December 31, 1995. RESULTS: Mean follow-up was 6.5 years, mean age was 50 years. Initial surgery was cystectomy, unilateral salpingo-oophorectomy and total hysterectomy with bilateral salpingo-oophorectomy in 22, 40 and 75 cases respectively. Eleven patients had residual disease. Serous, mucinous and Brenner tumors were observed in 67, 69 and 1 cases respectively. Staging was I, II, III in 117, 3, and 17 cases respectively with two pseudomyxomas. Adjuvant therapy was given in 15 patients. There was a recurrence in 15 patients and 14 died. The 5-year survival rate was 89.3%. Prognosis factors with an impact on survival rate were age, recurrence and type of surgery. Factors with a negative impact on recurrence were adjuvant therapy and residual disease after surgery. CONCLUSION: Careful staging followed by complete and radical surgery is essential. Unilateral salpingo-oophorectomy with omentectomy and multiple peritoneal biopsies may be indicated in younger patients undergoing radical surgery after pregnancy. Aduvant therapy is necessary for invasive implants.
