When an egg with no genetic information is released from the fallopian tube it can be fertilized by the sperm, but a molar pregnancy can occur. A molar pregnancy is the development of a tumor from the fertilized egg. The condition is extremely rare with only 1 in 1,500 pregnancies resulting in tumor growth. Researchers from the Department of Medical Oncology at Charing Cross Hospital recently published a study on the treatment outcomes of patients diagnosed with gestational trophoblastic tumors following the development of a molar pregnancy.

A total of 618 women treated for molar pregnancy at Charing Cross Hospital in London were included in the study - 547 with a complete molar pregnancy, 13 with a complete molar pregnancy and twin conception and 58 with a partial molar pregnancy).

Conclusion: Treatment for the molar pregnancy should result in a 100% cure rate, according to researchers. Reaching that cure rate requires prompt treatment and medical follow-up.
