Objective: To study the feasibility of endometrial sampling device as a sampling tool during the follow-up visit for endometrial cancer patients undergone conservative treatment.
Methods: Before the hysteroscopy examination, endometrial sampling device was used to take the endometrium specimens 43 times in 19 patients who had been diagnosed as endometrial cancer or atypical hyperplasia, and were undergone conservative treatment during May 2012 to Mar. 2013. All cases accepted vaginal ultrasound screening before every sampling by endometrial sampling device. The histological results were compared with those done by hysteroscopy.
Results: The average age of those patients was (30 ± 6) years old. The mean thickness of the endometrium during the treatment was (0.81 ± 0.65) cm. The qualified rate for the sampling was 95% (41/43). Compared with the specimens undergone by hysteroscopy direct sampling, 32 samples got by the endometrial sampling device with thicker endometrium (0.93 ± 0.70) cm had the same histological results, while the other 9 patients with thinner endometrium (0.40 ± 0.14) cm were not (P = 0.031).
Conclusion: The endometrial sampling device could be used during the follow-up visit for the conservative treatment patients with endometrial cancer or atypical hyperplasia, the vaginal ultrasound screening should be used together to figure out those with thinner endometrium.
