A2- Lung cancer Flashcards
(39 cards)
There three ways in which lung cancer present what are they?
Symptoms
Incidental pickup
Screening programme
What are the symptoms of lung cancer?
lung
Systemic
Metastases
Paraneiplastic syndromes
Complications
What are some lung related symptoms
Wheeze
Chest pain
Breathlessness
Hamoptysis
Cough
Systemic symptoms?
Weight loss
Lethargy
Loss of appetite
Symptoms of metastases?
Pain
confusion
weakness
balance problems
Symptoms of paraneoplastic syndromes?
Confusion
lethargy
pain
nausea and vomiting
thirst
There are two types of paraneoplastic syndromes?
What are they?
- Lung cancer can produce pTH related peptide which leads to hypercalcaemia
- SiADH syndrome leading to hyponatremia
Symptoms related to complications with lung cancer?
SVC obstruction could lead to:
Face swelling
Arm swelling
Dilated chest wall veins
WHat is the horners syndrome
Horner syndrome is a combination of signs and symptoms caused by the disruption of a nerve pathway from the brain to the face and eye on one side of the body. Typically, Horner syndrome results in a decreased pupil size, a drooping eyelid and decreased sweating on the affected side of your face
Horners syndrome triad?
- Mitosis (constricted pupils)
- partial ptosis
- Loss of hemifacial sweating (anhidrosis)
What kind of lung tumours are related to horners syndrome?
Apical
WHat imaging do you use to help diagnose lung cancer?
- CXR
- CT staging (chest + abdomen)
- MRI- brain/adrenal/liver
PET positron emission tomography- FDG uptake (fluorodeoxyglucose)
How do you tissue diagnose depending on the lesion?
If lesion is:
Central in airways- bronchoscopy
Lymph nodes- US guided FNA/biopsy OR EBUS
Peripheral- CT guided lung biopsy
Lesion distal from the centre- miniprobe bronchoscopy (radial EBUS)
Mediastinal lymph nodes- mediastinoscopy
WHat is EBUS
EBUS (endobronchial ultrasound) bronchoscopy
Which biopsy type is the least invasive
US guided FNA pf lymph node
Why is tissue diagnoses important?
Primary lung cancer vs metastases
small cell vs non small cell
adenocarcionoma vs squamous cell carcinoma
^all these tumours will be tested for PDL-1 (helps to assess when tumour will respond to immunotherapy) +adeno testing eg eGFR,ALK,ROS-1
An MDT meeting can be split into two?
Diagnostic MDT- looking at imaging
Treatment MDT
Who are the members of a lung MDT?
Role of resp physician in MDT
- present new patients/diagnostic phase
- Sumarise case so they:
- present key symptoms
- pmhx
- smoking history/other risk factors
- performance status
- lung function
- results of other key tests such as echo/CPEX
Role of Clinical Nurse Specialist in MDT
- Patients voice
- patients advocacy
- holistic needs
- updates and communication with patietns and familes in between OPA (outside outpaitent appointments)
Role of Radiologists in MDT
Interpret scans
- CXR
- CT
- US (eg supraclavicular LN)
- PET-CT
- MRI
Radiological staging
Advice regarding feasibilty of biopsy
Which of these factors would be a relative contraindication to CT guided lung biopsy?
- Peripheral lung lesion
- FEV1 0.75 litres
- Platelet count 160
- Haemoglobin 110 g/L
FEV1 0.75 litres
Role of Pathologists in MDT
- cytology + histology specimens
- pathologist specialises in one area
- cell type
- origin- immunohistochemistry
- Receptor status:
- eGFR/ALK/ROS-1?PDL-1
- NGS panel
Role of Clinical oncologists in MDT
- Advice on radiotherapy
- convention fractionated
- SABR (stereotactic Ablative Body Radiotherapy)
- Technical factors
