1. Risk of developing gestational trophoblastic neoplasia (GTN) after complete molar pregnancy found to be low when hCG levels normalize within 56 days of evacuation.
2. GTN risk percentages dependent on timing of hCG normalization.
3. Study suggests individualized surveillance protocols based on hCG normalization timing.
4. Most GTN cases diagnosed after standard 6-month surveillance period; common presenting symptoms include elevated hCG levels and vaginal bleeding.
5. Metastatic disease at diagnosis seen in about 26% of cases, often affecting lungs, brain, or vagina.
6. Some cases involved GTN originating from the original molar pregnancy.
7. Revised surveillance protocols could reduce unnecessary follow-up and improve family planning.
