Which of the following complication is more in subsequent pregnancies in a woman with history of gestational trophoblastic disease?
**Core Concept**
Gestational trophoblastic disease (GTD) is a group of rare tumors originating from trophoblastic cells that invade the uterus during pregnancy. It can lead to various complications in subsequent pregnancies, including an increased risk of developing another GTD.
**Why the Correct Answer is Right**
The correct answer is related to the concept of "coagulative" or "trophoblastic" immunization, which is a phenomenon where the body's immune system becomes sensitized to trophoblastic cells after a previous GTD. This immunization can lead to an increased risk of developing a more aggressive form of GTD in subsequent pregnancies. The increased risk is due to the body's immune response to the trophoblastic cells, which can trigger an exaggerated reaction.
**Why Each Wrong Option is Incorrect**
**Option A:** This option might be tempting, but it is not the most accurate answer. While there is an increased risk of GTD in subsequent pregnancies, it is not the most common complication.
**Option B:** This option is incorrect because the risk of developing another GTD is not directly related to the size of the initial tumor.
**Option C:** This option is incorrect because the risk of GTD in subsequent pregnancies is not directly related to the type of GTD (e.g., invasive mole, choriocarcinoma).
**Clinical Pearl / High-Yield Fact**
It is essential for clinicians to be aware of the increased risk of GTD in subsequent pregnancies and to closely monitor patients with a history of GTD.
**Correct Answer:** A. Increased risk of developing another GTD.
