Abstract
PURPOSE: To determine the rate of precancer and cancer in women presenting with PMB who have a visually atrophic endometrium at hysteroscopy and assess the value of endometrial biopsy in this situation and the adequacy of the samples obtained. METHODS: Retrospective reviews of all patients with a visually atrophic endometrium at hysteroscopy who had presented with PMB and had an ET > / = 4 mm or ET < 4 mm with focal changes or irregular features between 2013 and 2024 at University Hospitals of Derby and Burton were included (n = 1096). Patients who had previously had cancer or precancer or had unclear hysteroscopy findings were excluded. The endometrial biopsy histology result was considered the main outcome measure. RESULTS: 188 patients did not have a biopsy performed (17.15%), 660 patients had benign pathology (60.22%), and 239 patients had an inadequate sample result (21.81%). Nine patients had precancerous changes (0.82%). The rate of cancer was 0.00% (n = 0). The NPV of a visually atrophic endometrial cavity at hysteroscopy in detecting precancer or cancer was 99.2%. Patients with an ET < 4 mm pre-hysteroscopy and an atrophic endometrial cavity at hysteroscopy were 2.25 times more likely than those whose ET is > 4 mm to have an inadequate sample (p < 0.001, 95% CI 1.61-3.16). 10 patients who had an inadequate sample at initial biopsy had a repeat inadequate sample (n = 23, 43.48%). CONCLUSIONS: The incidence of precancer/cancer in patients presenting with PMB with a visually atrophic endometrium at hysteroscopy is low. Many patients within this cohort have an inadequate sample at biopsy, and therefore, repeat sampling is of questionable value.
