Cancer - Testicular Flashcards
Main type of testicular cancer?
95% are Germ Cell Tumours
5% are Non-Germ cell tumours
Either Seminomatous GCT (30s/40s) or Non-seminomatous GCT (aka teratoma, 20s/30s)
5% are Non-GCT
What kinds of germ cell tumours are there and who do they affect?
Seminomatous germ cell tumour - 30/40 yr olds
Non-seminomatous germ celll tumour - AKA teratoma - affects 20-30 y/o’s
How does testicular cancer present?
Usually just a painless lump
Less often presents with:
- Tender inflammated swelling
- Trauma history
- Metastatic symptoms (chest/bone/para-aortic lymph nodes)
Differentials for testicular lumps?
Cancer
Infection - epididymo-orchitis
Epididymal cyst
A missed testicular torsion
Risk factors for testicular cancer?
Age - 3rd decacde Caucasian Infertility Testicular maldescent Atrophic testes
What tests can be done for Testicular Cancer?
MSSU
Testicular ultrasound/X-ray
Tumour markers
What tumour markers do you look for and what type of cancer do they indicate?
Alpha-fetoprotein (AFP) - Teratoma
Beta-HCG (Human chorionic Gonadotrophin) - Seminoma
LDH (Lactate Dehydrogenase)) - Non-specific
Initial testicular cancer treatment?
Radical Orchidectomy - may need to biopsy the other testes to make sure it has not spread
2y treatment?
Depends on the stage
- Low and neg markers = Surveillance and maybe RT/chemo
- Nodal/relapse/persistent markers = chemo or lymph node dissection
- Mets = needs chemo
Prognosis?
Very good
Stage 1 - 99% 5 yr survival
Stage 4 - 73% 5 yr survival
How do we grade testicular cancer?
Grade - Assesses aggression based on differentiation
Well differentiated = less aggressive
Poorly differentiated = very aggressive
How do we stage ?
Staging is the assessment of spread which occurs in 3 ways.
- Local - local invasion to nearby structures
- Regional - spread to lympatics
- Distant - invasion of lungs, bone, liver
Staged using TNM system
4 Stages of Testicular Cancer?
Stage 1 -Testis Disease
Stage 2 - Infradiaphragmatic nodes
Stage 3 - Supradiaphragmatic Nodes
Stage 4 - Extralymphatic Disease
