Clinical indications for hysteroscopic removal of uterine masses: Time, age at diagnosis, and mass size

초록

AimThe aim of this study was to investigate clinical factors associated with abnormal pathologies of uterine masses resected via hysteroscopy. MethodsWomen who underwent hysteroscopic surgery for presumptive diagnoses of abnormal endometrial or endocervical masses, such as polyps or leiomyomas on ultrasonography, between January 2012 and April 2015, were enrolled. Clinical and pathologic data were retrospectively reviewed. ResultsAmong 189 patients, pathologic diagnoses of the uterine mass were abnormal in 172 (91.0%) cases, including polyps in 119 (63.0%), leiomyomas in 49 (26.0%), endometrial hyperplasia in two (1.0%), and endometrial cancer in two (1.0%). Seventeen (9.0%) women who underwent hysteroscopic removal showed unremarkable results on pathology, and the most common finding among them was the proliferative phase of the normal endometrium. Women aged over 40 years with uterine masses and a time since last menstrual period of over 15 days are four times more likely to be diagnosed with neoplastic masses than others (odds ratio [OR], 4.39, 95% confidence interval [CI], 1.33-14.48 and OR, 4.22, 95%CI, 1.35-13.21, respectively); those with masses over 1.5 cm in size are three times more likely to be neoplastic than others (OR, 3.08, 95%CI, 1.04-9.12). ConclusionLarge mass size, longer time after last menstrual period, and older age are risk factors for abnormal histologies of uterine masses resected via hysteroscopy. Clinicians should take particular care when contemplating hysteroscopic removal for women younger than 40 years, and those with masses of <1.5 cm in size in the proliferative phase of the endometrium to avoid an unnecessary surgery.
