63
Q

Summarize the epidemiology and management of EGFR-mutated lung adenocarcinomas.

A

Usually young, asian, women, non-smokers. Often a bronchioloalveolar histologic type. Exons 19 & 21.

Many TKIs available (gefitinib, erlotinib), but mutations can confer resistance (T790M?).

64
Q

Summarize the epidemiology and management of KRAS-mutated lung adenocarcinomas.

A

Usually smokers. Mucinous and solid histologic types?

Negative predictor for response to TKIs.

65
Q

Summarize the epidemiology and management of EML4-ALK rearranged lung adenocarcinomas.

A

Young, non-smoker, higher stage. Often with mucin and signet-ring cells.

Requires FISH to identify rearrangements. Targetable with crizotinib.

66
Q

Summarize the mutational and targeted landscape of colon adenocarcinomas.

A

KRAS mutations most common.

BRAF in 10% (predicts poor EGFR response)

EGFR overexpression otherwise targetable with cetuximab/panitumumab

UGT1A1 polymorphism may confer Irinotecan resistance

67
Q

Summarize the mutational landscape and treatment of melanoma.

A

Half are BRAF V600E mutated, targetable with BRAF/MEK inhibitors.

A minority are c-Kit mutated, targetable with imatinib. Usually in acral and mucosal sites.

68
Q

Summarize the mutation landscape and treatment of GIST.

A

Most are c-Kit mutated (target with imatinib). Some are PDGFRA mutated. A few are wild-type or have SDH1 mutations.

The response to imatinib is assessed by molecular testing for the type of KIT mutation.

69
Q

What role does VHL play in formation of RCC?

A

Mutations in VHL result in loss of degradation of HIF, in turn overexpressing CAIX, VEGF, and PDGF.

Maybe targetable with VEGF/PDGF and mTOR inhibitors.

70
Q

Summarize the mutational landscape and treatment of breast carcinomas.

A

ER/PR expression is targetable with tamoxifen (gold standard: IHC on FFPE sections)

HER2 overexpression is targetable with trastuzumab or lapatinib+capecitabine

71
Q

What tumors besides breast can be treated with trastuzumab?

A

Some gastric of GEJ adenocarcinomas can overexpress HER2. More common with intestinal histology.

72
Q

What targeted therapy can be used to treat some PTCs?

A

BRAF inhibitors (mutated in 30-50%).
