Following suction evacuation of a complete hydatidiform mole, serum β-hCG monitoring should be performed at what interval until three consecutive normal levels are obtained, followed by further monitoring?

• A Weekly until normal, then monthly for 6 months ✓
• B Weekly until normal, then monthly for 12 months
• C Every 2 weeks until normal, then monthly for 6 months
• D Weekly until normal, then every 2 weeks for 6 months

Explanation

After molar evacuation, β-hCG is measured weekly until three consecutive normal levels are achieved. Thereafter, monitoring continues monthly for 6 months for complete moles (6 months of normal hCG total). Contraception is advised throughout follow-up. Partial moles are followed monthly after normalization without the 6-month extension. This protocol is essential for early detection of gestational trophoblastic neoplasia.
