Lung ca Flashcards
Where does lung ca metastasise to
Brain
liver
Adrenals
Bone
3 most important genetic mutations to know in lung adenocarcinoma
EGFR (almost always happens in adenocarcinoma)
ALK
ROS1 (rare)
Can use targeted agents!
How do you get Horner’s syndrome in lung cancer?
Compression of sympathetic chain (apical tumour)
Which type of lung ca commonly presents with paraneoplastic syndrome?
Small cell
What is the most common type of mutation in NSCLC?
KRAS
But no targeted agents at the moment
What stage is the lung ca if there is also a pleural or pericardial nodule?
stage 4
What stage is the lung ca if there is tumour in the contra-lateral lung?
Stage 4
What needs to be done urgently with newly diagnosed small cell lung cancer?
Urgent chemotherapy
Urgent CT staging including brain (MRI preferred)
Brain radiotherapy if mets present
Treatment of stage 1 or 2 NSCLC
Lobectomy PLUS mediastinal LN resection with curative intent
PLUS adjuvant chemo (cisplatin) for stage 2
If unfit, sterotactic radiotherapy
Treatment of stage 3a (non-bulky) NSCLC
Lobectomy OR/AND radiotherapy PLUS chemotherapy
Treatment of stage 3a (bulky) NSCLC
Chemoradiotherapy followed by durvalumab (PD1 inhibitor)
Regardless of PD1 status
What investigations must you do in stage 4 NSCLC?
Test for driver mutations - EGFR, ALK, ROS1
AND PD1 status (if no driver mutation; comes second only!)
= Will direct therapy!
Treatment of stage 4 NSCLC with EGFR mutation
EGFR TKI - Erlotinib
2nd line: orsimertinib (if T790 mutation aka resistance)
Treatment of stage 4 NSCLC with ALK mutation
ALK TKI - Alectinib
Treatment of stage 4 NSCLC with ROS1 mutation
ALK TKI - crizotinib
