What is Testicular Mixed Choriocarcinoma and Embryonal Carcinoma?
Testicular Mixed Choriocarcinoma and Embryonal Carcinoma is a malignant mixed germ cell tumour originating in the testicles. It is distinctively marked by the presence of both choriocarcinoma and embryonal carcinoma cell types. Germ cell tumours are derived from germ cells, which are the cells that develop into sperm in men. These cells are normally found in the testicles but can sometimes be found in other parts of the body if they migrated improperly during fetal development. Mixed germ cell tumours contain more than one type of germ cell cancer. In the case of Testicular Mixed Choriocarcinoma and Embryonal Carcinoma, the tumour contains both choriocarcinoma and embryonal carcinoma cells. Choriocarcinoma is a highly malignant form of germ cell tumour, characterized by the presence of cytotrophoblasts and syncytiotrophoblasts, the cells responsible for the formation of the placenta during pregnancy. It is very aggressive and can spread quickly throughout the body, often leading to symptoms caused by metastasis to other organs, such as the lungs. Embryonal carcinoma, on the other hand, is a primitive type of germ-cell tumour that resembles early embryonic tissue. While it is less aggressive than choriocarcinoma, it can still spread to other parts of the body if not treated in a timely manner.Symptoms
Symptoms of testicular mixed choriocarcinoma and embryonal carcinoma can include:- A lump in one of the testicles
- Testicular pain or discomfort
- Swelling in the testicles
- Lower back pain or shortness of breath if the cancer has spread to the lungs
- Unusual hormonal changes, which can cause symptoms like gynaecomastia (enlarged breasts in males)
Disease Aetiology (Causes)
The exact cause of testicular mixed choriocarcinoma and embryonal carcinoma is unknown. Some known risk factors for testicular cancer include a family history of the disease, having an undescended testicle, or abnormal testicle development.Diagnosis
Diagnosis of testicular mixed choriocarcinoma and embryonal carcinoma often involves:- Taking a detailed medical history and performing a physical examination
- Conducting an ultrasound of the scrotum to see the internal structures of the testicles
- Doing blood tests for tumour markers, like alpha-fetoprotein (AFP), human chorionic gonadotropin (HCG), and lactate dehydrogenase (LDH)
- Carrying out a biopsy, where a small sample of testicular tissue is removed and examined under a microscope
Treatment
The treatment for testicular mixed choriocarcinoma and embryonal carcinoma typically includes:- Surgery: Orchiectomy, the surgical removal of the affected testicle, is the primary treatment.
- Chemotherapy: This treatment method is often used after surgery to kill any remaining cancer cells. It’s also used to treat advanced or metastatic cases.
- Radiation Therapy: While it’s not the first line of treatment for these types of testicular cancer, it may be used in certain circumstances.
