Which of the following is a key differentiating factor between gestational and non-gestational choriocarcinoma?
Understand the Problem
The question asks to identify the key difference between gestational and non-gestational choriocarcinoma. Understanding these differences is important for accurate diagnosis and treatment planning.
Answer
Gestational choriocarcinoma occurs after pregnancy, while non-gestational choriocarcinoma arises independently of pregnancy.
A key differentiating factor is the history of a previous pregnancy. Gestational choriocarcinoma develops after a pregnancy (normal, molar, or ectopic), while non-gestational choriocarcinoma arises independently of pregnancy, often from germ cells.
Answer for screen readers
A key differentiating factor is the history of a previous pregnancy. Gestational choriocarcinoma develops after a pregnancy (normal, molar, or ectopic), while non-gestational choriocarcinoma arises independently of pregnancy, often from germ cells.
More Information
Gestational choriocarcinoma is more sensitive to chemotherapy than non-gestational choriocarcinoma.
Tips
A common mistake is to assume that all choriocarcinomas are related to pregnancy. Non-gestational forms exist and arise from germ cells.
