Q

What would we expect to see in a chest x-ray regarding the mediastinum?

A
  1. Hilar vascular structures should be crisply defined
  2. No widening of mediastinum
  3. Trachea should be central

Q

Lung cancer can be difficult to spot on a chest x-ray so what should we look out for?

A

Fludeoxyglucose (18F)

24
Q

What is FDG?

A

Labelled glucose analogue

26
Q

Describe the classification for a T1 tumour.

A

Tumour ≤3 cm in greatest dimension, surrounded by lung or visceral pleura, without bronchoscopic evidence of involvement of the main bronchus

27
Q

Describe the classification of a T2 tumour.

A

Tumour >3 cm but 5 cm
OR
A tumour with any of the following:
-Involves main bronchus, but not carina
-Invades visceral pleura
-Associated with atelectasis or obstructive pneumonitis that extends to the hilar region involving part or all the lung

28
Q

Describe the classification of a T3 tumour.

A

Tumour >5 cm but <7cm
OR

A tumour which invades any of the following-
-chest wall (including superior sulcus tumors)
-phrenic nerve
-parietal pericardium
-separate tumour nodule(s) in the same lobe as the primary

29
Q

Describe the classification of a T4 tumour.

A

Tumour >7cm
OR

A tumour which invades any of the following-
-diaphragm
-mediastinum
-heart
-great vessels
-trachea
-recurrent laryngeal nerve
-oesophagus
-vertebral body
-carina

30
Q

In which classification of cancer would there be separate tumour nodule(s) in a different ipsilateral lobe?

A

T4

31
Q

What can PET scans be useful for?

A

Assessing chest wall or mediastinal invasion

32
Q

In regards the the TMC screening, what does N0 mean?

A

No regional lymph node metastases

33
Q

In regards the the TMC screening, what does N1 mean?

A

Ipsilateral peribronchial , hilar or intrapulmonary nodes including by direct extension

34
Q

In regards the the TMC screening, what does N2 mean?

A

Ipsilateral mediastinal or subcarinal nodes

In regards the the TMC screening, what does N3 mean?

A

Contralateral mediastinal nodes, contralateral hilar, scalene or supraclavicular

36
Q

How does size of a lymph node relate to the likelihood of it metastasising?

A

The bigger the lymph node it, the more likely it’ll metastasise.

37
Q

In regards to TMC screening, what does M0 mean?

A

No distant metastasis

38
Q

In regards to TMC screening, what does M1 mean?

A

Distant metastasis

A

Used to sample mediastinal nodes

43
Q

What is mediastinotomy used for?

A

Used to sample anterior mediastinal nodes
