Q

Criteria for thoracic radiotherapy in SCLC

A

Limited disease:
Alongside cycle of chemo OR after chemo if good partial response within thorax

Extensive disease:
After chemo if complete response at distant sites and good partial response within thorax

17
Q

Prognosis of SCLC limited vs extensive disease

A

Limited: 18-30 months
Extensive: 7-12 months

18
Q

How to stage NSCLC

A

TNM staging to convert into stage 1-4

19
Q

Describe stage 1A NSCLC

A

Tumour 3cm or less

No spread to LN

20
Q

Describe stage 1B NSCLC

A

Tumour 3-5cm

No spread to LN

21
Q

Describe stage 2 NSCLC

A

Tumour up to 7cm

+/- spread to peribronchial or hilar LN

22
Q

Describe stage 3A NSCLC

A

Tumour extends into surrounding tissue

Spread to ipsilateral LNs

23
Q

Describe stage 3B NSCLC

A

Spread to contralateral LNs
Or
Subcarinal or mediastinal LN spread with >1 tumour

24
Q

Describe stage 4 NSCLC

A

Metastatic spread i.e palliative

25
Treatment of stage 1 and 2 NSCLC
Surgical resection + adjuvant chemo if >4cm | For non-operable: radical radiotherapy if performance score 0-1
26
Treatment for stage 3 NSCLC
Chemoradiotherapy Radical radiotherapy Palliative chemotherapy Palliative radiotherapy
27
Treatment for stage 4 NSCLC
Palliative care: Chemotherapy Immunotherapy Targeted therapy
28
First line targeted therapy for Non-squamous lung cancers | Give examples
EGFR tyrosine kinase inhibitors | Gefitinib and erlotinib
29
Examples of targeted therapy drugs for NSCLC
EGFR tyrosine kinase inhibitors | Pembroluzimab
30
How do EGFR tyrosine kinase inhibitors work
Prevents KRAS mediated effects in the EGFR pathway therefore it prevents cell proliferation, cell survival and metastasis
31
Describe the mechanism of action of pembroluzimab
Monoclonal antibody Binds to PD1 receptor on T cells Prevents T cell from binding to PD-L1 and PD-L2 on tumour cells Reactivates T cell mediated immunity against the tumour cells
