Q

What is the management protocol for bladder cancer if it is non muscle invasive?

A

Non Muscle Invasive

  • If low grade and no CIS (carcinoma in situ) then consideration of cystoscopic surveillance +/- intravesicular chemotherapy/BCG
27
Q

What is the management protocol for bladder cancer which is muscle invasive?

A

Cystectomy
Radiotherapy
+/- chemotherapy
Palliative treatment

28
Q

What type of cancer is most prostate cancer?

A

Adenocarcinoma

29
Q

What are the risk factors for prostate cancer?

A

Increasing age, western nations, ethnicity

30
Q

In which other conditions is PSA raised in?

A

Inflammation eg UTI, Prostatitis and Benign Prostate Hyperplasia

31
Q

What is PSA?

A

enzyme which liquefies the ejaculate, and is used as a marker for prostate cancer

32
Q

If PSA is high, what is done to confirm next steps of treatment?

A

Multiparametric MRI before biopsy

33
Q

What is the method of biopsy done for the prostate?

A

Trans perineal prostate biopsy

34
Q

Why are trans perineal prostate biopsies prefered over transrectal?

A

less risk of infection and able to sample all areas of the prostate.

35
Q

What is the benefit of the multiparametric MRI?

A

Allows density of the PSA to be established, as sometimes the Prostate might just be enlarged in which case the PSA would be raised regardless

36
Q

What is the score used to grade prostate cancer?

A

Gleason score

37
Q

What are the levels of gleason score?

A

Since multifocal two scores based on level of differentiation

2-6 = Well differentiated
7 = Moderately differentiated
8 – Poorly differentiated

38
Q

What are the TNM stages for prostate cancer?

A

T1 – non palpable or visible on imaging
T2 – palpable tumour
T3 – beyond prostatic capsule into periprostatic fat
T4 – tumour fixed onto adjacent structure/pelvic side wall
N1 – regional LN (pelvis)
M1a- non regional LN
M1b- bone
M1x- other sites

39
Q

What is the management of prostate cancer in patients who are young and fit, and have high grade cancer?

A

Radical prostatectomy/Radiotherapy

40
Q

What is the management of patients who have low grade cancer and are young and fit?

A

Active surveillance (regular PSA, MRI and Bloods)

41
Q

What should PSA levels be post prostectomy?

A

Post prostatectomy – monitor PSA ( should be undetectable or <0.01ng/ml). If >0.2ng/ml then relapse

42
Q

What is the management plan in a patient with prostate cancer who is old / unfit, and has high grade cancer?

A

Hormone therapy - androgen replacement

43
Q

What is the management of prostate cancer if old and unwell, with low grade cancer?

A

Watchful waiting with regular PSA testing

44
Q

Why might bladder function be affected in a prostectomy?

A

The prostate contains the proximal sphincteric unit, which controls some degree of urinary continence. Prostatectomy removes the proximal urethral sphincter and there is a risk of inadvertent damage to the cavernous nerve to the prostate (which provides neural innervation to the bladder and urethra) resulting in bladder function being affected(3).

45
Q

What happens to urethral length in a prostectomy?

A

Moreover, urethral length changes during the operation which can also affect continence

46
Q

Damage to what structure causes erectile dysfunction in a prostectomy?

A

Cavernous nerve

47
Q

Which muscle does a prostectomy remove?

A

proximal urethral sphincter

48
Q

What does the cavernous nerve innervate?

A

Bladder and urethra

49
Q

What are the three broad classifications of testicular tumours?

A

Germ cell tumour
Sex cord tumours
Miscellaneous

50
Q

What are the three most common types of testicular tumours?

A
  1. Seminoma
  2. Spermatocytic seminoma
  3. Teratoma differentiated
51
Q

What is the difference between stage 1A, 1B and 1S testicular cancers?

A

1A - patients have tumours limited to testis and epididymis, no vascular or lymphatic involvement and no signs of metastasis

1B - more locally invasive primary tumour, but no sign of metastatic disease

1S - persistently elevated serum tumour marker levels, indicating subclinical metastatic disease

52
Q

What is AFP?

A

Alpha feto-protein - serum tumour marker

53
Q

In which situations is AFP elevatd?

A

Elevated in patients with yolk sac component within a teratomatous germ cell tumour

54
Q

Where is AFP usually synthesized?

A

normally synthesised by fetal yolk sac, liver , intestine

55
Q

What are the three main serum tumour markers?

A

AFP
beta sub unit of HCG
lactate dehydrogenase (LDH)

56
Q

What cells secrete HCG?

A

Secreted by placental syncitiotrophoblastic cells

57
Q

What cancers produce HCG?

A

choriocarcinomas

58
Q

What is LDH a marker for?

A

general tumour marker

59
Q

Which investigations are done for testicular cancer?

A

Abdominopelvic CT
Chest CT
Bone Scan / MRI

60
Q

What is radical Orchidectomy?

A

Removal of the testes through the abdominal wall

61
Q

What are the pathological prognostic factors in stage 1 disease (testicular cancer)?

A

1.Seminoma
- tumour size (>4cm)
- rete invasion (stromal)

  1. Non-seminomatous tumours (NSGCT)
    - lymphovascular invasion
    - presence (and extent) of embryonal carcinoma
