A history of cesarean delivery increases the risk of postmolar gestational trophoblastic neoplasia by 45%. This finding supports current management but suggests increased vigilance for patients with prior cesarean delivery.
Area of Science:
- Gynecology
- Oncology
- Reproductive Medicine
Background:
- Gestational trophoblastic neoplasia (GTN) can arise after hydatidiform mole.
- Cesarean delivery is a common obstetric procedure with potential long-term effects.
- The association between prior cesarean delivery and GTN risk is not well-established.
Purpose of the Study:
- To investigate if a history of cesarean delivery impacts the risk of developing postmolar gestational trophoblastic neoplasia.
- To determine if cesarean delivery history influences the clinical aggressiveness or chemoresistance of GTN.
Main Methods:
- Retrospective cohort study at two international GTD reference centers.
- Analysis of 2,904 patients with hydatidiform mole, comparing those with and without prior cesarean delivery.
- Multivariable logistic regression to identify predictors of postmolar GTN and chemoresistance.
Main Results:
- Prior cesarean delivery was independently associated with a 45% increased risk of postmolar GTN (aOR 1.45).
- The number or indication for prior cesarean deliveries did not significantly modify this risk.
- Cesarean delivery history did not correlate with increased chemoresistance in low-risk GTN patients.
Conclusions:
- A history of cesarean delivery is a risk factor for developing postmolar GTN.
- Findings support current GTN surveillance protocols.
- Patients with prior cesarean delivery warrant heightened clinical vigilance during postmolar surveillance.

Type 1 diabetes is characterized by autoimmune-mediated destruction of pancreatic β cells, with environmental factors potentially triggering this process in genetically susceptible individuals. Despite many not having a family history, certain genes increase susceptibility,...
