Germ Cell Tumors Cancer from Diagnosis to Treatment
What Are Germ Cell Tumors?
Germ Cell Tumors are tumors that develop from germ cells - the cells responsible for producing sperm in males and eggs in females.
Although they usually occur in the testicles | testicular cancer and ovaries | ovarian germ cell tumors, they can also appear in other areas of the body, such as:
Mediastinum | chest
Retroperitoneum | abdomen
Brain | pineal or suprasellar regions
GCTs can be benign or malignant and affect both children and adults.

Types of Germ Cell Tumors
GCTs are divided into two main categories
Seminomatous Germ Cell Tumors
These tumors grow slowly and respond well to treatment.
Types:
Seminoma | testicular
Dysgerminoma | ovarian
Non-Seminomatous Germ Cell Tumors
These tend to grow more aggressively.
Types:
Embryonal carcinoma
Yolk sac tumor
Choriocarcinoma
Teratoma
Mixed germ cell tumors

• Dull ache in the lower abdomen or groin
• Back pain
• Gynecomastia | breast enlargement in men - rare
Ovarian
• Abdominal pain or bloating
• Pelvic mass
• Irregular periods
• Feeling of fullness
• Early puberty in children
Mediastinal/Abdominal
• Chest pain or breathing difficulty
• Coughing
• Abdominal mass
• Back pain
Brain Germ Cell Tumor
• Headaches
• Vomiting
• Vision changes

3. Diagnostic Procedure
Medical History & Physical Exam
Exam of testicles, abdomen, or pelvis depending on symptoms.
Tumor Marker Blood Tests
Alpha-fetoprotein
beta-human chorionic gonadotropin
Lactate dehydrogenase
Imaging Tests
Ultrasound:
First test for testicular or ovarian tumors
CT Scan:
Detects spread
MRI:
For brain or spinal tumors
PET Scan:
Reveals active cancer cells
Biopsy
Testicular tumors:
Usually removed completely | orchiectomy | instead of biopsy
Ovarian and mediastinal tumors:
Tissue biopsy confirms diagnosis
Brain GCTs:
Neurosurgical biopsy
Staging
Stages depend on:
Tumor size
Spread to lymph nodes
Distant metastasis
Tumor marker levels

4. Treatment Options
➛ Surgery
Orchiectomy | testicle removal
Oophorectomy | ovary removal
Tumor excision for mediastinal or abdominal masses
Neurosurgery for brain tumors
➛ Chemotherapy
Common regimens:
Bleomycin + Etoposide + Cisplatin
Etoposide + Cisplatin
Etoposide + Ifosfamide + Cisplatin
Used for both seminomatous and non-seminomatous GCTs.
➛ Radiation Therapy
Effective mainly for seminomas and dysgerminomas
Used rarely for NSGCT due to resistance
➛ High-Dose Chemotherapy + Stem Cell Transplant
Used for recurrent or resistant germ cell tumors.
➛ Fertility Preservation
Sperm banking
Egg or embryo freezing
