Endometrial sampling in patients with trophoblastic disease after suction curettage.

To determine intrauterine pathology in patients with postmolar gestational trophoblastic neoplasia (GTN) and hydatidiform mole after suction curettage. Safety profiles of endometrial sampling in this setting are also evaluated.
In this prospective study, 24 cases with persistent GTN or postevacuation hydatidiform mole were recruited. Endometrial pathology was evaluated by Endocell. Clinical characteristics, safety of the instrument and pathology results were analyzed.
During August 2006 to July 2007, 15 cases with postmolar GTN and 9 cases of postevacuation mole were recruited. Of 15 cases of postmolar GTN, 2 (13%) showed molar tissue. All 9 cases of postevacuation hydatidiform mole showed benign endometrial tissue or normal trophoblast in endometrial sampling pathology. No patients in this study had severe vaginal bleeding or infection after endometrial sampling. Analysis of endometrial sampling pathology as a diagnostic test for GTN showed a sensitivity of 0.133 (95% CI 0.037-0.379).
Endometrial sampling by Endocell is safe in patients with gestational trophoblastic disease. Although the pathology findings from endometrial sampling had low sensitivity in diagnosing GTN, we encourage a larger prospective trial to confirm this result.
