Objective: To examine the evaluative effect of preoperative transvaginal color Doppler sonography (TVCDS) screening and phasing of endometrial carcinoma.
Methods: A total of 713 jeopardized endometrial carcinoma patients were screened by TVCDS. The investigators observed the endometrium form, focus location, size and echo, measured the endometrium thickness, judged the regularity and integrity of edge, the integrity of faint echo halos at the interface between endometrium and muscularis and the blood flow inside focus, examined resistance index and determined endometrial carcinoma as well as muscularis infiltrating extent. According to the FIGO's phasing scheme in 1988, endometrial carcinoma was divided into I, II, III and IV phases so as to compare the results of TVCDS in screening and phasing of endometrial carcinoma with that of operative pathology.
Results: One hundred cases were diagnosed as endometrial carcinoma. Among which, 96 were proved by surgical pathology as endometrial carcinoma. The rates of TVCDS screening and phasing coincidence were 96% (96/100) and 94% (94/100) respectively.
Conclusion: The application of TVCDS may diagnose and stage the cases of endometrial carcinoma. It is a valuable tool for selecting therapeutic regimens and making prognostic evaluations.
