Guidelines
New updated guidelines effective from 1st July 2023
Data analysis of over 17,000 women diagnosed with a Complete Hydatidiform Mole in the UK shows that:
If the hCG level normalises within 56 days from the date of evacuation, with a follow up confirmatory normal blood hCG 4 weeks later, the detection rate of persistent disease is extremely low.
Therefore, for women diagnosed with a complete mole with hCG normalisation within 56 days of the date of the evacuation, the national gestational screening service has deemed it is safe to no longer require hCG monitoring for a 6 month period.
These women can be discharged once their blood and a confirmatory hCG level is normal.
They can try again for a new pregnancy.
For those women with a complete mole who take more than 56 days for their hCG to fall to normal after the date of evacuation, the original 6 months of further normal hCG monitoring remains in place at present.
New update effective from 1 December 2020
In keeping with practice throughout the UK we will be reviewing all histology cases, we request the relevant paraffin blocks and slides are sent:

PLEASE CONTINUE TO REGISTER ALL PTS FOR F/UP FOLLOWING A MOLAR PREGNANCY
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.
Therefore:
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.
