Understanding Choriocarcinoma Symptoms and Treatments
Choriocarcinoma is a rare but aggressive type of cancer that originates in the trophoblastic cells, which are cells that form part of the placenta during pregnancy. While it predominantly affects women, particularly those who have experienced molar pregnancies, it can also present in males, though this is exceedingly rare.

Get A Second OpinionWhat is Choriocarcinoma?
Choriocarcinoma is a type of gestational trophoblastic disease (GTD) characterised by the abnormal proliferation of trophoblastic cells. These cells are responsible for nourishing the embryo and developing into a large part of the placenta. Choriocarcinoma can occur following any type of pregnancy but is most commonly associated with molar pregnancies, a type of gestational trophoblastic neoplasia (GTN).
Pathophysiology of Choriocarcinoma
The pathophysiology of choriocarcinoma involves the rapid and uncontrolled growth of trophoblastic cells. These cells invade the uterine wall and can spread to other parts of the body, including the lungs, liver, brain, and kidneys. The aggressive nature of these cells makes early detection and treatment crucial for a favorable prognosis.
Types of Choriocarcinoma
Choriocarcinoma can be classified into two primary types:
- Gestational Choriocarcinoma: This type arises from a pregnancy-related event, such as a molar pregnancy, miscarriage, ectopic pregnancy, or normal pregnancy.
- Non-Gestational Choriocarcinoma: This rare type occurs in both males and females and is unrelated to pregnancy. In males, it often presents in the testicles and is a type of germ cell tumor.
Symptoms of Choriocarcinoma
Common Symptoms in Females
- Abnormal Vaginal Bleeding: This is the most common symptom and may occur during or after pregnancy.
- Pelvic Pain: Persistent pain in the pelvic region can be an indicator.
- Elevated hCG Levels: Human chorionic gonadotropin (hCG) levels are usually significantly elevated in affected individuals.
Symptoms in Males
- Testicular Mass: A lump or swelling in the testicles may be observed.
- Gynecomastia: Enlargement of breast tissue due to hormonal changes.
General Symptoms
- Shortness of Breath: Due to lung metastasis.
- Headaches: Resulting from brain metastasis.
- Abdominal Pain: Linked to liver involvement.
Diagnosis of Choriocarcinoma
Clinical Examination
A thorough medical history and physical examination are the first steps in diagnosing choriocarcinoma. Physicians look for signs like abnormal vaginal bleeding, pelvic pain, and elevated hCG levels.
Laboratory Tests
- CG Levels: Elevated levels of hCG are a hallmark of choriocarcinoma and are measured through blood tests.
- Complete Blood Count (CBC): To check for anemia or other blood abnormalities.
Imaging Studies
- Ultrasound: Used to visualize the uterus and ovaries.
- CT Scan: Helps in identifying metastasis to other organs.
- MRI: Provides detailed images of soft tissues and is useful in assessing brain involvement.
- Chest X-Ray: To detect lung metastasis.
Biopsy
A biopsy may be performed to obtain a tissue sample for histological examination, confirming the diagnosis and ruling out other types of cancer.
Treatment Options for Choriocarcinoma
Chemotherapy
Chemotherapy is the cornerstone of choriocarcinoma treatment. The choice of regimen depends on the stage and spread of the disease. Common drugs include methotrexate, dactinomycin, and etoposide.
Surgery
Surgical intervention may be required in cases where the tumor is localized and resectable. Hysterectomy is a common procedure for women who do not wish to preserve fertility.
Radiation Therapy
Radiation therapy is less commonly used but may be considered in cases where the cancer has spread to the brain or other critical areas.
Targeted Therapy
Research is ongoing into targeted therapies that specifically attack cancer cells without harming normal cells. These treatments hold promise for the future of choriocarcinoma management.
Prognosis and Follow-Up
The prognosis for choriocarcinoma varies depending on the stage at diagnosis and the success of initial treatment. Early-stage choriocarcinoma has a high cure rate with appropriate chemotherapy. Regular follow-up is essential to monitor hCG levels and detect any recurrence.

Book an AppointmentPrevention and Risk Reduction
Regular Monitoring
Women with a history of molar pregnancy or other GTD should undergo regular monitoring of hCG levels to detect any recurrence early.
Avoiding Risk Factors
While many risk factors for choriocarcinoma are unavoidable, such as prior molar pregnancy, maintaining overall reproductive health and seeking prompt medical attention for abnormal symptoms can help in early detection.
Genetic Counseling
In rare cases of non-gestational choriocarcinoma, genetic counseling may be recommended to understand any underlying genetic predispositions.
Frequently Asked Questions
1. What are the symptoms of choriocarcinoma?
Symptoms include abnormal vaginal bleeding, pelvic pain, enlarged uterus, and sometimes metastasis to lungs or brain causing headaches.
2. How can choriocarcinoma be prevented?
Prevention includes early diagnosis of molar pregnancies and close monitoring after miscarriage or childbirth in high-risk women.
3. What causes choriocarcinoma?
Choriocarcinoma is caused by the abnormal growth of trophoblastic tissue, often following a molar pregnancy, miscarriage, or childbirth.
4. What are the types of choriocarcinoma?
Types include gestational choriocarcinoma, which is related to pregnancy, and non-gestational choriocarcinoma, which is very rare in males.
5. What are the treatment options for choriocarcinoma?
Treatment involves chemotherapy, radiation therapy, and sometimes surgery, especially in cases with metastasis.
