Lung cancer Flashcards

1
Q

Epidemiology of lung cancer - how common is it, what is the prognosis like?

A

Lung cancer is the 3rd most common lung cancer in the UK. More common in men than women.

It contributes to 21% of all cancer deaths and the 5 year survival rate is 10%.

Q

When is a patient sent for a 2 week wait urgent referral?

A
  1. over 40 y/o with unexplained haemoptysis

Q

What neoplastic syndromes is small call lung cancer associated with?

A
  • SIADH
  • Cushing’s
  • Lambert Eaton syndrome

Q

Management of small cell lung cancer

A
  1. Chemotherapy and radiotherapy
  2. Surgery is not appropriate because the tumour type has a very fast doubling time
  3. Brain and chest radiotherapy can be used to reduce risk of metastases
  4. Often relapse quickly after chemotherapy so prognosis is short

Q

What are the typical features and clinical presentation of squamous cell carcinoma of the lungs?

A
  1. Tumour is centrally close to bronchi
  2. Associated with cigarette smoking
  3. Hypercalcaemia associated as tumour can secrete PTH
  4. Digital clubbing common

Q

What are large cell carcinomas of the lung most associated with?

A
  • Early metastasis
  • Gynaecomastia
  • Galactorrhoea
14
Q

What is mesothelioma?

A

Tumour in the pleura, linked to asbestos exposure. Causes chest pain, SOB, weight loss and pleural thickening.

14
Q

What is a carcinoid tumour of the lung?

A

A slow growing, neuroendocrine tumour that releases serotonin. Can cause serotonin syndrome

15
Q

Pancoast tumours of the lung - what are they, where are they and what are the signs and symptoms?

A

An adenocarcinoma or squamous cell carcinoma of the apex of the lung.

Causes compression of the nerves (recurrent laryngeal) and blood vessels. This causes bovine cough and hoarseness.

Associated with Horner’s syndrome too.

16
Q

General presentation of all lung cancers

A
  1. Cough (persistent)
  2. Dyspnoea
  3. Haemoptysis
  4. Pleuritic chest pain
  5. Associated metastatic pain e.g. bone pain, headaches, RUQ pain
17
Q

Management of non small cell lung cancer

A

Stage 1 and 2 -
Surgery and adjuvant chemo

Radiotherapy given for more peripheral tumours and symptomatic disease and met associated pains

Chemo is the mainstay of treatment for patients with metastatic or locally advanced disease either Carboplatin and Gemcitabine or Carboplatin/Cisplatin and Pemetrexed

Docetaxel as second line

18
Q

Contraindications for surgical tx of lung cancer(s)

A

Superior vena cava obstruction
Poor FEV1
Malignant pleural effusion
Vocal cord paralysis

19
Q

What is malignant pleural effusion?

A

A pleural effusion that develops as a direct extension of cancer into the pleural space, or due to inflammation induced by malignancy.

MPEs are most commonly secondary to lung cancer, with adenocarcinoma type most frequently associated with the development of pleural effusion.

20
Q

Small cell lung cancer management

A

Vast majority of patients will receive palliative chemotherapy and prophylactic radiotherapy to the brain for prevention of mets (cranial irridation).

CISPLATIN + ETOPOSIDE are used in this chemotherapy.

21
Q

Prognosis of small cell lung cancer

A

Without chemotherapy or other treatment types = 2-4 months
With chemotherapy = 6-12 months
