BACKGROUND In 2012, the recommendation for immediate contact and visit to obstetric institutions by pregnant women was emphasized by The Japan Obstetric Compensation System for Cerebral Palsy (JOCSC). In this study, we examined whether or not the increased awareness has led to the improvement of perinatal outcomes of placental abruption managed at private clinics. METHODS We reviewed the obst...

gestational trophoblastic neoplasia ( gtn) is one of the most common gynecologic tumors in our country. despite development of effective chemotherapy: some cases remain resistant and if there is only focus of tumor, resection would be indicated.we present a young woman with stage 1 persistant gtn showing no response to chemotherapy. transvaginal sonograpy revealed trophoblastic tissue in the ut...

It is over 100 years since Felix Marchand identified choriocarcinoma as a tumor arising from placental villous trophoblast. In 1956, Hertz etal 1 first reported the cure of a patient with metastatic choriocarcinoma using chemotherapy. The next decade saw Hertz and colleagues at the National Institute of Health, Brewer in Chicago and Bagshawe in London develop the chemotherapeutic approach to ge...

It is now well established that human placenta secretes a protein hormone Human Placental Lactogen (HPL), also referred to as placental Somatomarnmotropin. It shows immunological crossreactivity with pituitary growth hormone and possesses both mammotropi.c and somatotropic effects (Jasiomovich and Maclaren, 1962, Kaplan and Grumbach 1968). This hormone is produced by syncytiotrophoblast layer o...

Trophoblastic neoplasms are a truly fascinating set of diseases that arise from a failed gestation. A molar pregnancy is an allograft of fetal tissue typically containing only paternal chromosomes that may invade the maternal decidua following a failed gestation that may have arisen up to decades earlier. Choriocarcinoma (CCA), the most common malignant form of trophoblastic disease, represente...

As epithelioid trophoblastic tumor (ETT) shares similar clinical features with other gestational trophoblastic neoplasms (GTNs), it is likely to be clinically misdiagnosed and subsequently treated in an improper way. This study aimed to identify the sonographic features of ETT that are distinct from other GTNs, including placental site trophoblastic tumor (PSTT) and invasive mole/choriocarcinom...

Gestational trophoblastic disease (GTD) represents a spectrum of lesions characterised by an abnormal proliferation of trophoblast, including complete hydatidiform mole, partial hydatidiform mole, invasive hydatidiform mole, choriocarcinoma, placental site trophoblastic tumour, epithelioid trophoblastic tumour, placental site nodule and plaque, and exaggerated placental site reaction. Complete ...

From the published data, the present mini-review attempts to answer two fundamental questions about the gestational trophoblastic neoplasms. In addition, it extrapolates the findings to other cancers that produce small amounts of hCG and how a novel therapies could be developed.
