23
Q

What is the prognostic value of Gleason score?

A

6 - 4-30% risk of death
7 - 42-70%
8-10 - 60-87%

24
Q

How is localised prostate cancer staged?

A

Digital rectal examination
PSA
MRI
CT
Bone scan - distant staging

25
Q

What does T1 and T2c mean in staging by DRE?

A

T1 - impalpable disease
T2c - both lobes

26
Q

What are the 4 clinical stages of prostate cancer?

A

Localised stage
Locally advanced stage
Metastatic stage
Castrate-resistant/ Hormone refractory stage

27
Q

What is included in the D’Aminco risk classification for localised disease stage?

A

PSA
Gleason sum score
Clinical T stage
10 year risk of biochemical recurrence

28
Q

What is the treatment for low risk localised prostate cancer?

A

Active surveillance
Surgery - lap, robotic or open
EBRT
Brachytherapy

29
Q

What is the treatment for intermediate and high risk localised prostate cancer?

A

Surgery for intermediate
Then EBRT and brachytherapy
HT - hormone therapy

30
Q

What is the treatment for locally advanced prostate cancer?

A

Watchful waiting
Hormone therapy followed by surgery or radiation
Hormone therapy alone
Intermitted HT

31
Q

What are the types of hormonal therapy for prostate cancer?

A

Surgical castration
Chemical castration
Anti-androgens
Oestrogens

32
Q

Explain chemical castration in treatment for prostate cancer

A

LHRH analogues eventually downregulates androgen receptors by negative feedback
Tumour flare in first week so need anti-androgens
LHRH antagonists do not cause flare

33
Q

Explain anti-androgens in treatment for prostate cancer

A

Inhibits androgen receptors
Not effective on its own - used with LHRH analogue

34
Q

Explain oestrogen in treatment for prostate cancer

A

Inhibits LHRH and testosterone secretion, inactivates androgens and has cytotoxic effects on prostate epithelial cells

35
Q

What is the complications with hormone therapy for prostate cancer?

A

Bone - pain, fractures, anaemia and spinal cord compression
Rectal - constipation and bowel obstruction
Ureteric - obstruction
Pelvic lymphatic obstruction
Lower urinary tract dysfunction

36
Q

What is standard treatment for metastatic prostate cancer?

A

Immediate hormonal therapy
Plus docetaxel in fit patients
Abiraterone and Enzalutamide combined as alternate with HT and steroids

37
Q

Describe the hormone refractory phase

A

Reached in 18-24 months of HT
Management continues with HT and Docetaxel, Abiraterone or Enzalutamide
Alternative is chemo

38
Q

What is the presentation of testicular cancer?

A

Usually - painless lump
Less often - tender inflamed swelling, history of trauma, para-aortic lymph nodes, bone and chest

39
Q

What are the risk factors of testicular cancer?

A

Undescended testis, infertility, atrophic testis, genetic abnormalities, chromosomal abnormalities, race (Caucasian) and previous cancer in contralateral testis

40
Q

What is a precursor lesion of of testicular cancer?

A

Testicular germ cell neoplasia in-situ (TGCNIS)

41
Q

When is peak incidence of testicular cancer?

A

In 3rd decade

42
Q

How is testicular cancer diagnosed?

A

Lump in testis - can be infection, epidydimal cyst and missed testicular torsion
MSSU
Testicular US
Tumour markers

43
Q

What are the types of tumour markers in testicular cancer?

A

AFP - teratoma
BHCG - seminoma
LDH - non specific biomarker of tumour burden
Up to 70& of patients have abnormal tumour markers

44
Q

For testicular cancer, the main lymphatic spread to regional lymph nodes occurs in which group of lymph nodes?

A

Para-aortic lymph nodes

45
Q

What is used for treatment in testicular cancer?

A

Radical orchidectomy using inguinal incision centred over inguinal canal

46
Q

Is biopsy done in testicular cancer?

A

Biopsy not performed as risk to tumour seedling along biopsy track
May need biopsy of normal contralateral testis if high risk germ cell neoplasia in situ

47
Q

What are the types of germ cell tumour?

A

Seminomatous GCT - mainly 30-40 yrs old
Non-seminomatous GCT - mainly 20-30 yrs old and often mixed

A

(sex cord/ stromal cells)
Leydig
Sertoli
Lymphoma - rare

49
Q

How is testicular cancer graded?

A

Based on histological assessment of differentiation
Low grade - well differentiated
High grade - poorly differentiated

50
Q

How is testicular cancer staged?

A

Local staging
Nodal staging - CT scan of para-aortic lymph nodes
Distant staging - CT scan
Tumour markers
TNM staging

51
Q

What are the stages of testicular cancer?

A

Stage 1 - confined to testis
Stage 2 - infra-diaphragmatic para-aortic lymph nodes involved
Stage 3 - supra-diaphragmatic para-aortic lymph nodes
Stage 4 - extra-lymphatic disease (lungs, liver and bone)

52
Q
