Q

Type 2 papillary RCC

A

FH mutation

23
Q

VHL gene

A

tumor supresssor that regulates angiogenesis and cell proliferation. turns off wit hypoxia–>allows HIFa–> (VEGF, PDGF, TGF/EGFR). Mutation is constitutively off

24
Q

sorafenib for RCC

A

improved PFS 5.9v 2.8mo compared to placebo, only 2% PR but 78% SD.

25
Q

sorafenib/nexavar tox

A

RASH, hand/food in high proportions.

26
Q

first line RCC

A

sunitinib (biggest trial), bev+IFN, pazopanib (smaller trial), temsiroliumus (poor risk). no comparatives with each other.

27
Q

high risk RCC first line

A

temsirolimus (better than IFN or IFN/tem), IV weekly. more SD, low ORR.

28
Q

tox, temsirolimus

A

rash, LE dema, stomatitis, hypergly, HL, thrombocytopenia, dyspnea. (borderline DM tips them over)

29
Q

sunitinib toxicity

A

fatigue is most common to require dose reduction. others include HTN, nausea, hand/food, 13% with EF cardiac function. get baseline TTE, and yearly TTE.

30
Q

pazopanib tox

A

less fatigue, hand food, stomatitis, but more liver toxicity

31
Q

pazopanib v. sunitinib (COMPARZ)

A

1100pts, NONINFERIOR. sunitinib more fatigue, count suppression. pazopanib has more LFTs, and hair color changes.

32
Q

pazopanib LFT ab

A

if prolonged, then switch to sunitinib

33
Q

everolimus versus placebo in RCC

A

approved for third line

34
Q

tox of everolimus

A

pneumonitis.

35
Q

axitinib for RCC

A

most selective for VEGF. improved PFS compared to sorafenib in 2nd line setting.

36
Q

tox of axitinib

A

diarrhea, HTN.

37
Q

when to give everolimus?

A

either second line or beyond, doesn’t really matter when

38
Q

nivolumab dosing in RCC

A

phase II, Motzer: measure PFS, ORR was 20% across all arms, and durable response, most of them more than year. OS for group, 24 month OSS. now a phase III nivo versus everolimus following progression on a VEGFR.

39
Q

Birt-Hogg-Dube

A

-ch1, -Y. associated with chromophobe and oncocytoma variation. also has pulmonary nodules/hamartomas.

40
Q

hereditary papillary RCC

A

associated with c-met activating mutation, or hydratase inactivating mutation

41
Q

Stauffer syndrome

A

paraneoplastic liver failure that reverses with nephrectomy for RCC

42
Q

VHL syndrome

A

RCC, retinal angiomas, hemangioblastomas of CNS, pheochromocytomas

43
Q

VHL genetics

A

loss of VHL–>loss of ubiquitinization of HIF1a–>increased HIF1a–> increased VEGF/PDGF

44
Q

medullary carcinoma of kidney

A

associated with sickle cell

45
Q

type I papillary RCC

A

good prognosis

46
Q

type II papillary RCC

A

associated with poor prognosis

47
Q

treatment of RCC with bev

A

bev+IFN better than IFN alone; monotherapy is not tested

48
Q

first line RCC, good risk

A

pazopanib or sunitinib; pazopanib- less fatigue/hand food, thrombocytopenia, mucositis; more LFT abnl

49
Q

high risk RCC

A

only temsirolimus approved. 3 or more of the following: LDH, Hgb, Ca,

50
Q

second line good risk RCC Tx

A

axitinib OR everolimus. sorafenib worse than axitinib

51
Q

IL-2 for RCC

A

can use if good PFS and clear cell variant, in first line

52
Q

chemotherapy for RCC

A

if sarcomatoid- gem/dox; if collecting duct- gem/cis; if clear cell- gem/5-FU(or xeloda)

53
Q

treatment of mTOR-associatead pneumonitis

A

grade 1- ASx radiographic- monitor and continue; grade 2- Sx mild- hold and give steroids, then dose reduce.
