[Evaluation of combined use of ultrasonography and beta-hCG determination in diagnosis of pelvic lesions of malignant trophoblastic disease].

The results of combined use of ultrasonography and beta-hCG determination for diagnosis of pelvic lesions of malignant trophoblastic disease in 73 cases were reported. Abnormal ultrasonograms and elevated beta-hCG levels were found in 53 of 55 cases of invasive mole and all 20 cases of choriocarcinoma. The location and extent of the pelvic lesions were clearly defined by ultrasonography. Moreover, there was a high correlation rate between ultrasonograms and beta-hCG levels. Surgico-pathological diagnosis was available in 17 cases. Based on these data, the authors emphasize that in improving the accuracy of diagnosis and locating the pelvic lesions ultrasonography in combination with beta-hCG determinations should be used as a routine procedure in suspected cases of pelvic lesion of malignant trophoblastic disease.
