Academic Publications in Fetal Medicine


The Fetal Medicine Team has a wide research interests not only  in Down syndrome screening and prenatal genetic diagnosis, but also in preterm birth, fetal growth restriction, as well as fetal therapy. The following are the highlights of our publications.


Down Syndrome Screening

Our unit have long and strong track record in studying the implementation of first trimester combined screening for Down syndrome since 2003 (Leung et al UOG 2007, Leung et al JMFNM 2009). We have derived the Chinese specific logarithm in risk calculation (Leung et al AJOG 2008, Sahota et al UOG 2009a, Sahota UOG 2009b, Sahota UOG 2010). Training and prospective quality control_ program are essential in maintaining high detection rate (90%) and low false positive rate (5%) of the screening program (Sahota et al JNFNM 2011Sahota et al JNFNM 2012).


Prenatal Genetic Diagnosis

CUHK is the pioneer in using circulating fetal DNA in maternal plasma for non-invasive prenatal diagnosis (Chiu et al BMJ 2011, Cheung et al NEJM 2015, Leung et al Prenat Dx 2013), to which the Fetal Medicine Team had made a significant contribution. The Team also studied the various new genomic methods in prenatal diagnosis, including array comparative genomic hybridization (aCGH) (Leung et al UOG 2011), BAC-on Beads (Choy et al BJOG 2014), and massively parallel sequencing, which revealed their accuracy and effectiveness in clinical use.


Preterm Birth

Our studies have found that in our Chinese population the epidemiology and underlying causes of preterm birth are quite different from those of in Western countries (Hui et al In J GO 2014). Hence the predictive value of routine cervical length measurement at 20 weeks of gestation for preterm delivery is lower when compared to the Caucasians (Leung et al UOG 2005). More interestingly, our RCT on the prophylactic use cerclage pessary in preventing preterm delivery show negative result, in contrast to the Spanish study (Hui et al AJP 2013). We have also been studying various biochemical markers to predict the risk of preterm labor or delivery (Chim et al PLoS One 2012).


Fetal Growth Restriction

Our Chinese Specific Fetal Growth Charts (CRL: Sahota et al UOG 2009; BPD, HC, AC, FL: Leung et al UOG 2008) are highly evaluated by the Inter-growth Study Group. We have also been studying various biophysical and biochemical markers to predict fetal growth restriction (Leung et al UOG 2006, Leung et al UOG 2008, Pang et al Prenat Dx 2009, Law et al UOG 2009)


Fetal Therapy

Our Team is the leading centre of fetal therapy in Hong Kong and in China. We have reported the implementation of various therapeutic modalities for fetal abnormalities including fetoscopic laser coagulation for twin-twin transfusion syndrome (Lau et al CMJ 2004), radiofrequency ablation of umbilical cord for selective fetal reduction in complicated MC twin pregnancies (Lu et al Fetal Dx Tx 2013),  pleurodesis for fetal chylothorax using OK432 (Leung HKMJ 2012 ), and USG guided embolization of large chorioangioma (Lau et al BJOG 2003 ; Lau et al BJOG 2005; Cheng et al Fetal Dx Tx 2016)
