Q

What is the TMN staging for colorectal cancer?

A

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.

Q

What is screening?

A

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.

Q

What are latissimus dorsi flaps?

A

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.

Q

What is a TRAM flap?

A

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.

Q

What is a DIEP flap?

A

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.

41
Q

How is a sentinel node biopsy carried out?

A

An isotope contrast and a blue dye are injected into the tumour area. The contrast and dye travel through the lymphatics to the first lymph node (the sentinel node). The first node in the drainage of the tumour area shows up blue and on the isotope scanner. A biopsy can be performed on this node, and if cancer cells are found, the lymph nodes can be removed.

42
Q

What are some changes seen in the breast in cancer patients?

A

Lumps that are hard, irregular, painless or fixed in place
Lumps may be tethered to the skin or the chest wall
Nipple retraction
Skin dimpling or oedema (peau d’orange)
Lymphadenopathy, particularly in the axilla

43
Q

What does the screening programme entail?

A

The NHS breast cancer screening program offers a mammogram every 3 years to women aged 50 – 70 years.

44
Q

What are some cons to screening?

Anxiety and stress
Exposure to radiation, with a very small risk of causing breast cancer
Missing cancer, leading to false reassurance
Unnecessary further tests or treatment where findings would not have otherwise caused harm

cryotherapy – liquid nitrogen is sprayed on to the affected skin to freeze it. The procedure may be painful and the skin may remain a bit uncomfortable for a few days. The affected skin will scab over and fall off within a few weeks.

imiquimod cream or chemotherapy cream (such as 5-fluorouracil) – this is applied to the affected skin regularly for a few weeks. It may cause your skin to become red and inflamed before it gets better.
curettage and cautery – the affected area of skin is scraped away under local anaesthetic, where the skin is numbed, and heat or electricity is used to stop any bleeding, leaving the area to scab over and heal after a few weeks

photodynamic therapy (PDT) – a light-sensitive cream is applied to the affected skin and a laser is directed on to the skin a few hours later to destroy the abnormal cells. The treatment session usually lasts between 8 to 45 minutes. You may need more than 1 session

surgery – the abnormal skin is cut out under local anaesthetic and stitches may be needed afterwards.
