16
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
Q

Treatment of stage 1 and 2 NSCLC

A

Surgical resection + adjuvant chemo if >4cm

For non-operable: radical radiotherapy if performance score 0-1

26
Q

Treatment for stage 3 NSCLC

A

Chemoradiotherapy
Radical radiotherapy
Palliative chemotherapy
Palliative radiotherapy

27
Q

Treatment for stage 4 NSCLC

A

Palliative care:
Chemotherapy
Immunotherapy
Targeted therapy

28
Q

First line targeted therapy for Non-squamous lung cancers

Give examples

A

EGFR tyrosine kinase inhibitors

Gefitinib and erlotinib

29
Q

Examples of targeted therapy drugs for NSCLC

A

EGFR tyrosine kinase inhibitors

Pembroluzimab

30
Q

How do EGFR tyrosine kinase inhibitors work

A

Prevents KRAS mediated effects in the EGFR pathway therefore it prevents cell proliferation, cell survival and metastasis

31
Q

Describe the mechanism of action of pembroluzimab

A

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
