Q

What is causing the substantial increase in incidence of prostate cancer in recent years?

A

Some may be due to real increase in risk, but additionally the increased use of TURP and PSA testing may have increased the detection rate

Q

What is the role of diet in prostate cancer?

A

Controversial, but thought that high-fat, low-fibre, smoked foods and dairy produce may increase risk, whilst soya beans and retinoids appear to be protective

A

No lymph node involvement

39

A

Ipsilateral lymph nodes involved

40
Q

43
Q

What is M0 in prostate cancer?

A

44
Q

What is M1 in prostate cancer?

A

45
Q

(this was meant to be in investigations sorry)

What imaging investigations should be done in prostate cancer?

A
  • Plain x-rays of chest and any sites of bone pain
  • Transrectal ultrasound
  • Bone scan
46
Q

What are the basic grades of prostate cancer?

A
  • Well differentiated
  • Moderately differentiated
  • Poorly differentiated
47
Q

How can the grades of prostate cancer be further detailed?

A

Gleason grade

48
Q

How does the Gleason grade work?

A

It scores tumours on a scale of 1-10, where 10 is the most poorly differentiated

49
Q

What is the limitation of transurethral ultrasound?

A

Low specificity for malignancy

50
Q

What is the strength of transurethral ultrasound?

A

High specificity for assessing the integrity of the prostatic capsule

51
Q

What is transurethral ultrasound often combined with?

A

Needle biopsy

52
Q

What samples are taken in needle biopsy in prostate cancer?

A

At least 6 cores of tissue

53
Q

What is the role of MRI/CT in prostate cancer?

A

Used to investigate lymph node involvement

54
Q

What are the treatment options for early stage (T1 or T2) prostate cancer?

A
  • Watchful waiting
  • Radiotherapy
  • Radical prostatectomy
55
Q

What are the options for watchful waiting in prostate cancer?

A
  • Wait until patient presents with symptoms

- Active follow up of outpatients with regular PSA testing and physical examination

56
Q

What is the advantage of watchful waiting in prostate cancer?

A

Does not produce physical or sexual complications associated with other treatments

57
Q

What is the disadvantage of watchful waiting in prostate cancer?

A

May increase anxiety

58
Q

When is watchful waiting the best option in prostate cancer?

A

69
Q

What might LHRH antagonists cause initially?

A

Initial increase in testosterone levels, that can cause tumour flare for first 1-2 weeks

70
Q

What might the tumour flare in the first 1-2 weeks of LHRH antagonists cause?

A

Disease progression, causing;

  • Ureteric obstruction
  • Increasing bone pain
71
Q

How is disease progression caused by the tumour flare with LHRH antagonists prevented?
