Ovarian high-grade serous carcinoma with elevated β-human chorionic gonadotropin
Abstract
Rationale:
Human chorionic gonadotropin (hCG) is a glycoprotein hormone secreted by the syncytiotrophoblasts of the placenta. However, hCG (particularly β-hCG) is also expressed in many normal nontrophoblastic tissues. Here, we report the case of a 50-year-old woman diagnosed with ovarian high-grade serous carcinoma with elevated β-hCG, which was insensitive to chemotherapeutic drugs and had a poor prognosis.
Patient concerns:
A 50-year-old woman with abdominal distention was admitted to our hospital. Pelvic computed tomography and magnetic resonance imaging were highly suggestive of multiple metastases of ovarian cancer. Surprisingly, an elevation in β-hCG levels was also measured.
Diagnosis and interventions:
The patient underwent laparoscopic examination and was diagnosed with high-grade serous ovarian carcinoma. After 2 prior chemotherapies with paclitaxel and carboplatin, the patient underwent cytoreductive surgery and continued receiving chemotherapy. However, recurrent lesions were observed during the period of chemotherapy, and the level of β-hCG increased. Alternative chemotherapy with liposomal doxorubicin was administered, but it also had a poor therapeutic effect.
Outcomes:
The progression was rapid with a continuous increase in β-hCG levels, and the patient died 9 months after surgery.
Lessons:
Gynecologists should be aware of women with ovarian carcinoma with an elevated β-hCG level, which suggests a poor prognosis.
