Q

What is nephron/renal sparing surgery?

A

in a partial nephrectomy — also called kidney-sparing (nephron-sparing) surgery — the surgeon removes a cancerous tumor or diseased tissue and leaves in as much healthy kidney tissue as possible

26
Q

We can divide bladder cancer into non-muscle invasive and muscle invasive.

How do we manage each type?

A
27
Q

What is BCG?

A

BCG is a type of immunotherapy drug.

For bladder cancer, BCG is given directly into the bladder (intravesical).

This can make the bladder react in a way that makes the immune system get rid of cancer cells.

28
Q

What is the most common cancer in the UK for men?

A

prostate

29
Q

What type of cancer are the majority of prostate cancers?

A

adenocarcinoma

30
Q

Name some clinical features of prostate cancer.

A

usually asymptomatic unless metastatic

urinary symptoms are actually not that common

but can have metastatic symptoms, like bony pain

31
Q

What is PSA?

A

PSA liquifies the ejaculate

it can be tested for in blood tests and it is prostate-specific but not prostate-cancer specific

32
Q

When can PSA be elevated?

A

prostate cancer
UTI
prostatitis
BPH

33
Q

How do we investigate for prostate cancer?

A

blood tests

multiparametric MRI before biopsy
or
MRI targeted biopsy (gold standard)

transperineal prostate biopsy

34
Q

How is transperineal prostate biopsy graded?

A

/10, greater, higher risk

35
Q

How do we score prostate cancer?

A
36
Q

How do we TNM stage prostate cancer?

A
37
Q

Prostate cancer management is highly dependent on patient age/comorbidities and stage and grade of prostate cancer:

How do we manage someone who is:
- young and fit with high grade cancer?
- young and fit with low grade cancer?

A

high grade -> radical prostatectomy / radiotherapy
low grade -> active surveillance (regular PSA, MRI and biopsy)

38
Q

Prostate cancer management is highly dependent on patient age/comorbidities and stage and grade of prostate cancer:

How do we manage someone who is:
- old and unfit with high grade cancer?
- old and unfit with low grade cancer?

A

high grade/metastatic disease -> hormone therapy
low grade -> watching waiting (regular PSA)

39
Q

How do we manage post-prostatectomy?

A

monitor PSA (should be undetectable or <0.01ng/ml)

if >0.2ng = relapse

40
Q

What are the treatment side effects of prostatectomy? (4)

A

The prostate contains the proximal sphincter

Prostatectomy removes the proximal urethral sphincter and changes urethral length

Risk of damage to cavernous nerves (innervation to bladder and urethra)

Damage to cavernous nerves causes ED.

41
Q

Patients with suspected prostate cancer should undergo _____

A

MRI imaging

42
Q

Incidence of testicular cancer is ___

A

increasing

43
Q

How does WHO classify testicular cancers by ABC?

A

A: germ cell tumours
B: sex cord / gonadal stromal
C: miscellanenous

44
Q

Name some germ cell testicular tumours.

A
45
Q

Name some sex cord / gonadal stromal tumours.

A
46
Q

Name some miscellaneous tumours.

A

lymphoma
metastases
rete tumours
paratesticular tumours
mesenchymal (sarcomatous) tumours

47
Q

How can we classify primary tumours? (pT)

A
48
Q

What do these stages mean?
IA
IB
IS

A
49
Q

Name the 3 principal serum tumour markers for testicular cancer.

A

Alpha-fetoprotein (AFP)
B eta subunit of human chorionic gonadotropin (HCG)
Lactate dehydrogenase (LDH)

50
Q

Describe AFP as a testicular cancer serum tumour marker.

A
51
Q

Describe beta-subunit HCG as a testicular cancer serum tumour marker.

A
52
Q

Describe LDH as a testicular cancer serum tumour marker.

A
53
Q

What are the guidelines for diagnosis and staging of testicular cancer?

A
54
Q

How can we diagnose testicular cancer?

A
55
Q

What is a surgery to remove a testicle with cancer is called?

A

a radical inguinal orchiectomy

56
Q

For a seminoma, what is the pathological prognostic factor in a stage I disease?

A

tumour size >4cm
rete invasion (stromal)

57
Q

For a non-seminomatous tumour, what is the pathological prognostic factor in a stage I disease?

A
  • lymphovascular invasion
  • presence (and extent) of embryonal carcinoma
58
Q

What are some symptoms of penile cancer?

A
  • Inability/ difficulty / pain on retracting foreskin
  • Spraying of stream
  • Obstructive LUTS
  • Association with penile cancer
59
Q

What do we call the condition in which tight foreskin can’t be pulled back over the head of the penis.

A

phimosis

60
Q

What do we call an abnormal narrowing of the urethral opening? How can this present physiologically?

A

meatal stenosis

spraying of stream

61
Q

What can obstructive LUTS be caused by?

A

urethral stricture

62
Q

It is difficult to distinguish penile cancer from ____

A

benign penile dermatoses

63
Q

In penile cancer, you should also examine for regional inguinal ______ .

A

lymphadenopathy

64
Q

How do we TNM classify penile cancer?

A
65
Q

Incidence of penile cancer is ___ in LMIC.
Incidence of testicular cancer is ___ in HIC.

A

higher
higher
