T
What is AFP a marker of?
HCC
Germ cell tumours
Metastatic lung cancer
Neural tube defects
What are the features of tumour lysis syndrome?
This leads to hyperuricaemia, hyperphosphatemia, hyperkalaemia, and hypocalcaemia.
How is tumour lysis syndrome managed?
IV fluids
Rasbicurase
Allopurinol
Dialysis
ECG
How does rasburicase work?
It transforms uric acid into allantoin. Allantoin is more soluble in urine than uric acid, and more easily eliminated by the kidney.
What is the 2WW for colorectal cancer?
Under 40 = pain and weight loss
Under 50 = PRIC
Pain + rectal bleeding + IDA + change in bowel habits
Under 60 = change in bowel habits and IDA
What is the criteria for a 2WW for colorectal cancer under 40?
Weight loss and Pain (Winter Princess)
What are the criteria for a 2WW for colorectal in under 50?
Change in bowel habits
Rectal bleeding
IDA
S
Pain
What are the criteria for 2WW for colorectal in under 60?
IDA and abnormal bowel movements
What is the TMN staging for colorectal cancer?
T: Tis (carcinoma in situ/intramucosal cancer), T1 (extends through the mucosa into the submucosa), T2 (extends through the submucosal into the muscularis), T3 (extends through the muscularis into the subserosa), T4 (extends into neighbouring organs or tissues).
N: N0 (no regional lymph node involvement), N1 (metastasis to 1-3 regional lymph nodes), N2 (metastasis to 4 or more regional lymph nodes).
M: M0 (no distant metastasis), M1 (distant metastasis). Staging informs both the prognosis and the treatment plan.
What are the criteria for a screening programme?
Accurate test
Early phase
Important disease
Ongoing process
Understood treatment
What is screening?
Screening is a way of identifying apparently healthy people who may have an increased risk of a particular condition. The NHS offers a range of screening tests to different sections of the population.
The aim is to offer screening to the people who are most likely to benefit from it. For example, some screening tests are only offered to newborn babies, while others such as breast screening and abdominal aortic aneurysm screening are only offered to older people.
What are the features of basal cell carcinoma?
Discuss the treatment options for BCC?
Imiquimod, 5FU, diclofenac
Cautery, curretage, Mohs surgery
What are the stages of bladder cancer?
What are the treatments for bladder cancer?
What is the most common type of breast cancer?
DCIS Potential to become an invasive breast cancer (around 30%)
What are some of pathological markers of breast cancer?
Ductal Carcinoma In Situ (DCIS
Lobular Carcinoma In Situ (LCIS)
Invasive Ductal Carcinoma – NST
Invasive Lobular Carcinomas (ILC)
Inflammatory Breast Cancer
What are the treatments for breast cancer?
Wide local excision
Adjuvant therapies
Traztuzumab
Endocrine therapies
Radiotherapy
Where do most breast cancers metastasise to?
Metastasis (2 Ls 2 Bs)
You can remember the notable locations that breast cancer metastasis occur using 2 Ls and 2 Bs:
L – Lungs
L – Liver
B – Bones
B – Brain
What is the referral criteria for women with breast cancer?
An unexplained breast lump in patients aged 30 or above
Unilateral nipple changes in patients aged 50 or above (discharge, retraction or other changes)
An unexplained lump in the axilla in patients aged 30 or above
Skin changes suggestive of breast cancer
NON-URGENT for under 30
The NICE guidelines suggest considering non-urgent referral for unexplained breast lumps in patients under 30 years.
What is triple assessment?
Clinical assessment (history and examination)
Imaging (ultrasound or mammography)
Biopsy (fine needle aspiration or core biopsy)
Define neo-adjuvant, adjuvant and definitive?
Neoadjuvant therapy – intended to shrink the tumour before surgery
Adjuvant chemotherapy – given after surgery to reduce recurrence
Treatment of metastatic or recurrent breast cancer
What are some drawbacks of radiotherapy?
General fatigue from the radiation
Local skin and tissue irritation and swelling
Fibrosis of breast tissue
Shrinking of breast tissue
Long term skin colour changes (usually darker)
What are the three methods of breast reconstruction?
Immediate or delayed
Latissmus dorsi
Transversus rectus abdominis flap
DIEP flap
What are latissimus dorsi flaps?
Latissimus Dorsi Flap
The breast can be reconstructed using a portion of the latissimus dorsi and the associated skin and fat tissue. The tissue is tunnelled under the skin to the breast area.
“Pedicled” refers to keeping the original blood supply and moving the tissue under the skin to a new location.
“Free flap” refers to cutting the tissue away completely and transplanting it to a new location.
What is a TRAM flap?
The breast can be reconstructed using a portion of the rectus abdominis, blood supply and skin. This can be either as a pedicled flap (tunnelled under the skin) or a free flap (transplanted). It poses a risk of developing an abdominal hernia due to the weakened abdominal wall.
What is a DIEP flap?
Deep Inferior Epigastric Perforator Flap (DIEP Flap)
The breast can be reconstructed using skin and subcutaneous fat from the abdomen (no muscle) as a free flap. The deep inferior epigastric artery, with the associated fat, skin and veins, is transplanted from the abdomen to the breast. The vessels are attached to branches of the internal mammary artery and vein. This is a complex procedure involving microsurgery. There is less risk of an abdominal wall hernia than with a TRAM flap, as the abdominal wall muscles are left intact.
What are some treatments for oestrogen receptor positive breast cancer?
Fulvestrant (selective oestrogen receptor downregulator)
GnRH agonists (e.g., goserelin or leuprorelin)
Ovarian surgery
How is chronic lymphoedema managed?
Massage techniques to manually drain the lymphatic system (manual lymphatic drainage)
Compression bandages
Specific lymphoedema exercises to improve lymph drainage
Weight loss if overweight
Good skin care
When are women offered a sentinel node biopsy?
A sentinel lymph node biopsy may be used during breast cancer surgery where the initial ultrasound does not show any abnormal nodes.
