Q

Role of a bone scan?

A

Inject radioactive tracer into the bloodstream which attaches to ‘hot spots’.

25
UK breast cancer screening programme?
50-71 y/o every 3 years.
26
What imaging is often done in lobular breast cancer (cancer that starts in the milk glands)?
MRI - as difficult to appreciate on mammogram
27
Aim of radiotherapy vs chemotherapy in breast cancer?
Radiotherapy - reduce risk of LOCAL recurrence Chemotherapy - reduce risk of DISTANT recurrence

≥30y/o with unexplained breast lump or ≥50y/o with unilateral nipple changes e.g. discharge, retraction
29
What is mainstay of mx of SCLC?
Chemotherapy
30

≥40y/o with unexplained haemoptysis or CXR findings suggesting lung cancer or mesothelioma
31
What is the initial investigation in 2ww referral for lung cancer?
CXR
32
2ww referral for colorectal cancer?
≥40y/o with unexplained weight loss & abdo pain ≥50y/o with unexplained rectal bleeding ≥60y/o with unexplained iron deficiency anaemia OR alteration in bowel habot Positive FIT test (i.e. occult blood found in faeces)
33
3 most common cancers that spread to bone?
Breast Lung Prostate Also renal & thyroid
34
Stepwise mx of suspected MSCC?
1) 16mg dexamethasone (with PPI cover) 2) Urgent MRI spine (within 24h) 3) If MRI +ve for MSCC --> consider neurosurgical intervention or radiotherapy
35
3 most common cancers causing hypercalcaemia?
1) Renal 2) SCLC 3) Breast
36
Hypercalcaemia as a prognostic indicator in cancer?
Usually a poor prognostic sign - median survival in patients presenting with hypercalcaemia is 3-4 months.
37
Give 2 ways that malignancy can cause hypercalcaemia
1) Tumours release PTHrP (most common) --> measure PTH to exclude hyperparathyroidism (as can have both) 2) Osteolytic effects on bones
38
PTH levels in cancer releasing PTHrP?
Typically low due to negative feedback from hypercalcaemia
39
Stepwise mx of hypercalcaemia?
1) Rehydration with IV fluids 2) Stop thiazide diuretics, consider furosemide 3) Bisphosphonates 4) Consider calcitonin (if very high calcium and in refractory cases)
40
1st line bisphosphonate for hypercalcaemia of malignancy?
1) Pamidronate (Aredia) or 2)Coledronic acid (Zometa)
41
What can be considered in very high/refractory cases of hypercalcaemia?
Calcitonin
42
Role of calcitonin?
Calcitonin opposes action of PTH --> acts to reduce calcium levels in blood. Calcitonin is released by thyroid gland.
43
Define tachyphylaxis
Decreasing responsiveness to a drug when used repetitively.
44
Stepwise mx of SVCO?
1) 16mg dexamethsone (with PPI cover) 2) Depending on cause: - vascular stent (generally 1st option) - radiotherapy - chemotherapy - LMWH (if thrombus confirmed)
45
What investigation is needed to confirm and understand cause of SVCO?
CT thorax
46
Pathway for suspected ovarian cancer?
If presenting to GP with symptoms but NORMAL exam: 1) Ca125 2) If raised --> refer for urgent US of abdomen and pelvis 3) If abnormal US --> 2ww referral Immediate 2ww referral if physical exam at GP reveals either: 1) Ascites 2) Pelvic or abdominal mass (which is not obviously uterine fibroids)
47
What are some symptoms that would indicate the need for Ca125 test?
- persistent abdominal distension (bloating) - early satiety and/or loss of appetite - pelvic or abdominal pain - increased urinary urgency and/or frequency - new onset symptoms suggestive of IBS i.e. bowel changes (as IBS rarely presents for the first time in women of this age)
48
What investigation is next if Ca125 is found to be raised?
Arrange urgent US of abdomen and pelvis
49

2ww referral in a woman presenting with an unexplained palpable mass in or at the entrance to the vagina.
50
2ww referral for suspected vulval cancer?
2ww referral for women presenting with any of the following: - vulval lump - ulceration - bleeding

1) TV US + endometrial thickness (if >4mm) 2) Hysteroscopy & biopsy
54
What investigation can be perfromed for for histological confirmation of endometrial cancer if endometrial biopsy cannot be performed/will not be tolerated by the patient?
Hysteroscopy, dilatation and curettage (performed under GA)
55
An endometrial thickness of >5mm is associated with what % probability of endometrial cancer?
96%
56
Bladder cancer referral guidelines?
