Q

Testicular … is the diagnostic modality of choice for testicular cancer

A

Testicular USS is the diagnostic modality of choice for testicular cancer

17
Q

USS offers excellent visualisation and identifies likely malignant lesions (the diagnosis is confirmed with histology following an …). Its sensitivity approaches 100% in trained hands.

A

USS offers excellent visualisation and identifies likely malignant lesions (the diagnosis is confirmed with histology following an orchidectomy). Its sensitivity approaches 100% in trained hands.

18
Q

Bloods before an orchidectomy

A
  • FBC
  • Renal function
  • LFT
19
Q

Imaging before testicular cancer diagnosis

A

CXR: may identify pulmonary metastasis.

20
Q

In testicular cancer, tumour markers may be measured to support the diagnosis and offer prognostic information. However, normal levels do not exclude cancer and levels may be elevated in other pathologies. The three major markers are:

A 
Alpha-fetoprotein (AFP): may be seen in NSGCT, particularly the yolk sac subtype. AFP is not seen in pure seminoma.
Beta-human chorionic gonadotrophin (beta-hCG): may be seen in NSGCT, particularly the choriocarcinoma subtype. Can also be seen in seminomas.
Lactate dehydrogenase (LDH): general marker of increased cell turnover, may be raised in either seminomas or NSGCTs.
21
Q

Placental alkaline phosphatase may also be measured and is indicative of … (testicular cancer)

A

Placental alkaline phosphatase may also be measured and is indicative of seminoma.

22
Q

… should be discussed with patients prior orchidectomy.

A

Fertility should be discussed with patients prior orchidectomy.

23
Q

Testicular cancer two types

A

Seminomas

Non-seminomas (mostly teratomas)

24
Q

Risk Factors for testicular cancer (4)

A

Undescended testes
Male infertility
Family history
Increased height

25
Q

Testicular cancer
The typical presentation is a painless lump on the testicle. Occasionally it can present with testicular pain.

The lump will be:

A 
Non-tender (or even reduced sensation)
Arising from testicle
Hard
Irregular
Not fluctuant 
No transillumination
26
Q

Rarely, gynaecomastia (breast enlargement) can be a presentation of testicular cancer, particularly a rare type of tumour called a … cell tumour. About 2% of patients presenting with gynaecomastia have a testicular tumour.

A

Rarely, gynaecomastia (breast enlargement) can be a presentation of testicular cancer, particularly a rare type of tumour called a Leydig cell tumour. About 2% of patients presenting with gynaecomastia have a testicular tumour.

27
Q

Scrotal ultrasound is the usual initial investigation to confirm the diagnosis.

Tumour markers for testicular cancer are:

A 
Alpha-fetoprotein – may be raised in teratomas (not in pure seminomas)
Beta-hCG – may be raised in both teratomas and seminomas
Lactate dehydrogenase (LDH) is a very non-specific tumour marker
28
Q

Testicular cancer is staged with the Royal Marsden staging system:

A

Stage 1 – isolated to the testicle
Stage 2 – spread to the retroperitoneal lymph nodes
Stage 3 – spread to the lymph nodes above the diaphragm
Stage 4 – metastasised to other organs

29
Q

The common places for testicular cancer to metastasise to are:

A

Lymphatics
Lungs
Liver
Brain

30
Q

Management of any cancer is guided by a multidisciplinary team (MDT) meeting to decide the best course of action for the individual patient.

Depending on the grade and stage of testicular cancer, treatment can involve:

A

Surgery to remove the affected testicle (radical orchidectomy) – a prosthesis can be inserted
Chemotherapy
Radiotherapy
Sperm banking to save sperm for future use, as treatment may cause infertility

31
Q

Long term side effects of treatment are particularly significant, as most patients are young and expected to live many years after treatment of testicular cancer. Side effects include:

A 
Infertility
Hypogonadism (testosterone replacement may be required)
Peripheral neuropathy
Hearing loss
Lasting kidney, liver or heart damage
Increased risk of cancer in the future
32
Q

The prognosis for early testicular cancer is…

A

The prognosis for early testicular cancer is good, with a greater than 90% cure rate. Metastatic disease is also often curable. Seminomas have a slightly better prognosis than non-seminomas.

Patients will require follow-up to monitor for reoccurrence. This usually involves monitoring tumour markers, and may include imaging such as CT scans or chest x-rays.

33
Q

Seminomas vs non seminomas - which has a better prognosis

A

Seminomas have a slightly better prognosis than non-seminomas.

34
Q

Common pulmonary manifestation of metastatic choriocarcinoma on imaging is … metastases.

A

Common pulmonary manifestation of metastatic choriocarcinoma on imaging is cannonball metastases. They typically appear as multiple round well-defined pulmonary nodules representing hematological spread of the malignancy.
