What surgery is preferred?
Lobectomy with draining of LNs
What is the current management of stage IV lung Ca?
If PDL1 status >50%
- Pembrolizumab
If PDL1 status <50%
- Doublet platinum based chemotherapy
What is mx of ALK+ lung Ca?
1st line: Crizotinib traditionally, newer Alectinib - better CNS penetration
2nd line ceritinib
What is the mortality reduction with FOBT in colon Ca?
20-30%
What is the management of stage IV CRC?
Chemotherapy (FOLFOX/XELOX or FOLFIRI) plus;
Bevacizumab (VEGF inhibitor)
or
EGFR antibodies (cetixumab and panitumumab) - only if wildtype for KRAS, NRAS, and BRAF
What is the difference between right and left sided tumour in terms of mab treatment?
Do not benefit from EGFR antibodies (cetixumab/panitumumab)
Which mutation do you look for in met. melanoma?
