Sunitinib, a multikinase inhibitor, inhibits angiogenesis and cell proliferation, which may explain its anti-tumor activity. Sunitinib is first line recommendation due to its success in studies along with a tolerable side effect profile. Some of these adverse effects include mucositis, stomatitis, altered taste, anorexia, dyspepsia, nausea, vomiting, diarrhea, constipation, hypertension, asthenia, fatigue, fever, peripheral edema, rash, hand-foot syndrome, skin discoloration, dry skin, hair color changes, back pain, arthralgia, extremity pain, cough, or dyspnea (6,8).

Pazopanib is a small molecule tyrosine kinase inhibitor with multiple targets (8). These targets include VEGF receptors 1, 2, and 3, PDGFR-alpha and beta, and c-KIT. In one randomized controlled trial, Pazopanib demonstrated an increase of 5 months in progression-free survival(PFS) in patients who had undergone 1 …show more content…

Many of these targets are involved in angiogenesis, apoptosis, and tumor cell signalling. Common adverse effects of sorafenib include diarrhea, skin rash, fatigue, hypertension, and dry mouth (8). A randomized controlled trial comparing sorafenib treatment to IFN-alpha treatment showed better quality of life scores and fewer symptoms in the sorafenib treatment arm. In this trial, a stronger clinical benefit was demonstrated in patients who had progressed after treatment with IFN-alpha and switched to sorafenib treatment. This benefit was also shown in patients whose sorafenib dose was increased after progression on sorafenib treatment.Thus, sorafenib should only be used in selected patients that have already been on sorafenib at a lower dose and experienced disease progression or those who have been previously treated with IFN-alpha and experienced progression
