1

What percentage of patients with lung cancer present with advanced disease?

66%

2

What do you need to check when looking at a chest X-ray?

Name/marker/rotation/penetration

Lines/metal work

Heart

Mediastinum

Lung (zones - upper, middle, lower)

Bones

Diaphragm

Soft tissues

3

What are the first 4 things you should look at in a chest X-ray?

Name

Marker

Rotation

Penetration

4

What are the zones of the lungs in a chest X-ray?

 

Upper

Middle

Lower

5

What is A?

Mediastinum

6

What are you looking for in the mediastinum?

Hilar vascular structures crisply defined

No widening of mediastinum

Trachea should be central

7

What are you looking for in the lungs?

Compare upper, middle and lower zones

Look between ribs for lung detail

Remember to look 'behind' the heart

8

What is this?

Peripheral lung carcinoma

9

What is this?

Central lung carcinoma

10

How should we identify lung cancers on X-rays?

Compare with previous films

Always look at review areas

Remember lesions are often more subtle

11

What are the review areas of a chest X-ray?

Hila

Lung apices

Behind the heart

Behind the diaphragm

12

What is this?

Left hilar mass

13

What is this?

Right hilar mass

14

What is this?

Mass behind the heart

15

What is this?

Mass left costophrenic angle

16

What is this?

Right apex tumour

17

What could the clinical history for lung cancer include?

Increasing shortness of breath in smoker

History of pulmonary fibrosis

Recent haemoptysis

18

What follows taking a history and examining the patient?

CT

19

What should be evaluated using a CT scan?

Size

Shape

Atelectasis

Border

Density

Solid or non-solid

Dynamic contrast enhancement >25HU

Growth

20

What is atelectasis?

Collapse of lung resulting in reduced gas exchange

21

What is the collapse of the lung resulting in reduced gas exchange called?

Atelectasis

22

What is a pulmonary mass?

Opacity in the lung over 3cm with no medistinal adenopathy or atelectasis

23

What is an opacity in the lung over 3cm with no mediastinal adenopathy or atelectasis called?

Pulmonary mass

24

What is a pulmonary nodule?

Opacity in the lung up to 3cm with no mediastinal adenopathy or atelectasis

25

What is an opacity in the lung up to 3cm with no mediastinal adenopathy or atelectasis called?

Pulmonary nodule

26

What is the difference between a pulmonary nodule and a pulmonary mass?

Pulmonary mass is over 3cm and pulmonary nodule is up to 3cm

27

What could a solitary pulmonary nodule or mass be?

Lung cancer

Metastasis

Benign lung neoplasm

Infection

Vascular haemotoma

28

What could suggest a solitary pulmonary nodule or mass is a metastasis?

Previous history of breast. renal, seminoma or sarcoma cancer

29

What are examples of benign lung neoplasms?

Carcinoid

Hamartoma

30

What does the staging of lung cancer take into account?

Clinical history/examination

Performance status

Pulmonary function
