Urgent suspected Lung Cancer (Guidelines)
![](/media/f4mjw13e/nhsh-2024.jpg)
Lung cancer is a malignant tumour which grows in the tissues of the lung. It is the third most common cancer in the UK with an estimated life time risk of developing lung cancer being 7% for females and 8% for males.
Lung cancer is more commonly diagnosed in people aged 75 and over and is often diagnosed late with 46.1% of new lung cancers in England being stage 4 at diagnosis in 2018.
While over 90% of patients are symptomatic at presentation, symptoms can be vague and similar to other conditions more common in primary care.
This guideline is aimed at primary care clinicians to provide guidance regarding when to suspect lung cancer, what investigations to perform and when to make a referral to the urgent suspected lung cancer clinic.
Patients presenting with any of the following red flag symptoms/signs for lung cancer should undergo an urgent chest X-ray.
- Any unexplained haemoptysis
- New/ not previously documented finger clubbing
- Persistent or recurrent chest infection
- Cervical and/or persistent supraclavicular lymphadenopathy
- Thrombocytosis, platelets greater than 450 × 109/L where symptoms and signs do not suggest other specific cancer (see thrombocytosis NICE guideline https://cks.nice.org.uk/topics/platelets-abnormal-counts-cancer/)
Any patient who has consolidation on chest x-ray should have a repeat no more than 6 weeks later to confirm resolution regardless of hospital admission or not if:
- Symptoms/physical signs persist
- There is higher risk of underlying malignancy
- smokers
- aged over 50 years
Imaging
- CXR
Blood tests
- FBC
- U&E
- LFT
- Calcium
As this is a timed pathway CXR images and blood results must be available at the point of referral in order for the referral to be accepted and progressed appropriately. If they are not then the referral will be returned.
Patients meeting any of the following criteria should be referred to the urgent suspected lung cancer clinic.
Chest x-ray suggestive/suspicious of lung cancer including:
- Lung mass
- Pleural effusion
- Pleural mass
- Slowly resolving consolidation
Despite normal CXR
- Any of the above unexplained symptoms or signs persisting for more than 6 weeks
- Persistent haemoptysis in smokers/ex-smokers aged over 40
Alternative referral
- Normal chest x-ray for patients with Cervical and/or persistent supraclavicular lymphadenopathy - Urgent referral via Head and Neck suspected cancer pathway- Link to ENT guideline:
- Normal chest x-ray for patients with Thrombocytosis consider an alternative diagnosis including other cancers
