The hydatidiform mole patients with lung nodule ≥1.0cm will be randomized into 2 groups: A. treated with chemotherapy immediately, B. follow up until hCG level met FIGO diagnostic criteria of GTN (B1) or hCG level declined to normal spontaneously (B2). Lung nodule \<1.0cm will directly treated as group C
