New guidelines for post pregnancy screening of hCG effective from 1st July 2017
Data analysis of more than 13,000 GTD patients in the UK shows that:
The detection rate for recurrent GTD on routine post-pregnancy screening of women previously diagnosed with one molar pregnancy is extremely low.
For women previously treated with GTN post pregnancy monitoring should still be continued.
The national gestational screening service has deemed it safe to no longer require hCG monitoring for women post pregnancy who have had one previous molar pregnancy that has not required chemotherapy.
Guidelines for oral contraceptives - effective from 1 January 2014
Oestrogen and progestogens taken between evacuation of the mole and the return to normality of hCG values appear not to increase the risk of invasive mole or choriocarcinoma developing.
Therefore women may use oral contraceptives after molar evacuation, before the hCG returns to normal.
Patient registration for tumour marker monitoring of hydatidiform moles is now available online. UK gynaecologists registering women with one of the specialist centres (Dundee, London or Sheffield) for this disease should use the NHSnet online form. This website provides a secure system complying with DH standards and the Data Protection Act 1998.
To register a new patient via NHS net.
