Johansen G, Dahm-Kähler P, Staf C, et al. - Researchers conducted a nationwide cohort study based on prospectively recorded data in order to determine the efficacy of fertility-sparing surgery (FSS) in terms of reproductive outcomes by following FSS for borderline ovarian tumors (BOTs). In addition, they compared the safety of FSS vs radical surgery (RS). From the Swedish Quality Registry for Gynecologic Cancer (SQRGC), they assessed 277 women with BOTs; of these, 213 (77%) underwent FSS, 183 (86%) unilateral salpingo-oophorectomy, and 30 (14%) cystectomy. Observation revealed that following FSS, natural fertility was maintained; ART treatment was required in only 9%. Further, FSS seemed to result in equivalent survival outcome to RS.
