In fit patients with mets at dx and minimal symptoms, what provides the best survival strategy
Nephrectomy followed by IFN-alpha
Only approved as follow up therapy after failure of initial drug
Axitinib
How does HypoMg cause HypoK
Doesn’t allow K to exit ROMK channel, just enter
Most common metastatic site for RCC
Lymph Nodes
Route of Temsirolimus vs Everolimus
Weekly IV vs Daily Oral
Ifosfamide Toxicity
Hemorrhagic Cystitis (mesna)
At physiological Mg concentrations,
Mg occludes ROMK channel, preventing K from exiting cell
2 CYP substrates
TKIs, Rapamycins
Patients taking this drug have high potential for sepsis
Aldesleukin
Renal fxn in men vs women
Higher in men
Most drugs for adult RCC target
VEGF due to etiology from vHL mutations

Ineffective in adults
Chronic NSAID tx is not good for
elderly patients, especially if taking anti-HTN
Results of clinical trials with low dose intermittent pulse IL-2
Disappointing
Hepatic Dysfunction Tox
Dactinomycin
Admin of Aldesleukin
IV to hospitalized patients
Endogenous IFN activation results in transcriptional upregulation of
Genes responsible for Anti-viral, Anti-proliferative, and Anti-tumor activities
Low dose infusion of IL-2 leads to selective expansion of
A subset of NK cells that overexpress high affinity IL-2 receptor
