Sunitinib, a small molecule, is a multitargeted receptor kinase inhibitor which targets the vascular endothelial growth factor receptor and platelet-derived growth factor receptor as well as several others. Initially approved for the treatment of renal cell carcinoma as well as imatinib-resistant gastrointestinal stromal tumors, the activity of sunitinib has been explored in several other solid tumors including non-small cell lung cancer (NSCLC). An initial phase II trial in 63 previously treated NSCLC patients using a dose of 50 mg daily 4 of 6 weeks showed a response rate of 11.1% and a stable disease rate of 26.8%. The median time to disease progression and overall survival was 12.0 and 23.4 weeks, respectively. The principal toxicities included fatigue, pain, myalgias, nausea/vomiting, and hypertension. Three hemorrhagic deaths were reported (two pulmonary and one central nervous system). After this trial was completed, a subsequent sequential cohort of 47 previously treated NSCLC patients were treated on a continuous dosing schedule of sunitinib at 37.5 mg daily. A response rate of 2.1% was reported with a stable disease rate of 19.X%. The median time to progression was 12.3 weeks with a median survival time of 38.1 week. Toxicities were, in general, less frequent and similar to those noted in the initial trial. Sunitinib is currently being evaluated in combination with a number of standard regimens commonly used in NSCLC as well as a maintenance drug after first-line platinum-based treatment of advanced NSCLC. Results of these trials are eagerly awaited and will help define the role of sunitinib in the therapeutic approach to NSCLC.

Temsirolimus is a targeted therapy that inhibits mammalian target of rapamycin (mTOR), a central regulator of tumor cell responses to growth stimuli. Temsirolimus has a broad anticancer activity profile that impacts tumor cell growth, proliferation, and survival through its specific inhibition of mTOR. In a randomized phase III trial that enrolled previously untreated patients with advanced renal cell carcinoma (RCC) and poor prognostic features, temsirolimus significantly prolonged overall survival compared with interferon-alpha, a standard therapy (p = 0.008). Because of the results, temsirolimus was approved by the U. S. Food and Drug Administration for treatment and is considered a first-line treatment for patients with advanced RCC with poor prognostic features. Temsirolimus is administered at a flat weekly IV dose of 25 mg given over 30-60 minutes. Gastrointestinal disorders (stomatitis, anorexia, nausea, diarrhea, and vomiting), rash, fatigue, edema, infections, and dyspnea, as well as hematologic and metabolic laboratory abnormalities occur in patients receiving temsirolimus. Metabolic side effects include hyperglycemia, hypercholesterolemia, hypertriglyceridemia, and hypophosphatemia. Most adverse reactions associated with temsirolimus can be managed medically or addressed by supportive measures. Nurses can improve patient outcomes through early recognition of side effects and prompt interventions.

A 65-year-old man with left renal cell carcinoma RCC underwent hand-assisted laparoscopic nephrectomy. He was discharged on the 8th hospital day, but 2 days later he was admitted to the hospital again because of vomiting and abdominal pain. Abdominal computed tomography (CT) showed a narrow space between the superior mesenteric artery (SMA) and aorta as well as distension of the proximal duodenum. Upper gastrointestinal radiographic studies with gastrografin showed abrupt vertical cut-off sign of the third part of the duodenum. Therefore, we diagnosed SMA syndrome. We started conservative management by nasogastric tube and total parenteral nutrition through a central venous line. The patient was able to eat on day 24 and was discharged on day 34 after the treatment. SMA syndrome is considered as a postoperative complication after abdominal surgery, but it is extremely rare. To our knowledge, only 4 cases of SMA syndrome following nephrectomy have been reported and this is the first case of SMA syndrome following laparoscopic nephrectomy.

PURPOSE Pazopanib is an oral angiogenesis inhibitor targeting vascular endothelial growth factor receptor, platelet-derived growth factor receptor, and c-Kit. This randomized, double-blind, placebo-controlled phase III study evaluated efficacy and safety of pazopanib monotherapy in treatment-naive and cytokine-pretreated patients with advanced renal cell carcinoma (RCC). PATIENTS AND METHODS Adult patients with measurable, locally advanced, and/or metastatic RCC were randomly assigned 2:1 to receive oral pazopanib or placebo. The primary end point was progression-free survival (PFS). Secondary end points included overall survival, tumor response rate (Response Evaluation Criteria in Solid Tumors), and safety. Radiographic assessments of tumors were independently reviewed. Results Of 435 patients enrolled, 233 were treatment naive (54%) and 202 were cytokine pretreated (46%). PFS was significantly prolonged with pazopanib compared with placebo in the overall study population (median, PFS 9.2 v 4.2 months; hazard ratio [HR], 0.46; 95% CI, 0.34 to 0.62; P < .0001), the treatment-naive subpopulation (median PFS 11.1 v 2.8 months; HR, 0.40; 95% CI, 0.27 to 0.60; P < .0001), and the cytokine-pretreated subpopulation (median PFS, 7.4 v 4.2 months; HR, 0.54; 95% CI, 0.35 to 0.84; P < .001). The objective response rate was 30% with pazopanib compared with 3% with placebo (P < .001). The median duration of response was longer than 1 year. The most common adverse events were diarrhea, hypertension, hair color changes, nausea, anorexia, and vomiting. There was no evidence of clinically important differences in quality of life for pazopanib versus placebo. CONCLUSION Pazopanib demonstrated significant improvement in PFS and tumor response compared with placebo in treatment-naive and cytokine-pretreated patients with advanced and/or metastatic RCC.

What's known on the subject? and What does the study add? The side-effect of targeted agents is known. The clinician should be aware of the side-effects of targeted agents and how to prevent/diminish them, particularly in sequential and combination therapies. The aim of this review is to help physicians tailor targeted treatments for advanced renal cell carcinoma to suit patient needs and ensure maximum overall duration of response to therapy by providing a summary of the frequency and time of onset of adverse events (AEs) and by raising awareness of AE profiles. A PubMed literature search was performed, and papers on targeted therapy-related AEs were reviewed. The frequency, severity and management of targeted therapy-related AEs are discussed. Manageable AEs commonly reported with all the approved targeted agents include: fatigue, gastrointestinal disorders (diarrhoea, nausea, vomiting), hypertension, skin and subcutaneous tissue disorders. Life-threatening AEs are less common than manageable AEs and are usually class specific. Data suggest that long-term treatment with well-established targeted agents does not result in increased or unexpected AEs. Caution is required with regard to the long-term use of newer targeted agents for which there are no long-term tolerability data or clinical experience. Studies have reported that the type and frequency of observed AEs associated with sequential tyrosine kinase inhibitor (TKI) use are similar to those reported in the literature for TKI monotherapy. Having an awareness of the AE profiles of targeted agents allows the development of effective management strategies. Generally, more extensive clinical experience has accumulated, and AE profiles are more predictable, for well-established targeted agents.

The rapid evolution of targeted therapies has had a dramatic impact on multiple domains in oncology, particularly metastatic renal cell carcinoma (RCC). Four agents antagonizing vascular endothelial growth factor-mediated signaling have been approved for the treatment of metastatic RCC, including the monoclonal antibody bevacizumab and the small molecular inhibitors sunitinib, sorafenib, and pazopanib. Pazopanib was approved in 2009 for this disease on the basis of a phase III clinical trial demonstrating a superior progression-free survival compared to placebo in 435 patients with either treatment-naive or cytokine-refractory disease. The trial offered insight related to the toxicity profile associated with this agent. The most common clinical adverse events are diarrhea, hypertension, nausea, anorexia, and vomiting. With respect to laboratory adverse events, hepatotoxicity represents a specific concern with pazopanib. Oncology nurses play a critical role in counseling patients regarding the toxicity profile and management of adverse events in pazopanib treatment.

On June 14, 2010, the European Commission issued a conditional marketing authorization valid throughout the European Union for pazopanib for the treatment of advanced renal cell carcinoma. Pazopanib is an antineoplastic agent that inhibits multiple receptor tyrosine kinases. The recommended oral dose is 800 mg once daily. The benefit of pazopanib is an increased progression-free survival. In the pivotal trial VEG105192, the median progression-free survival was 9.2 months (95% confidence interval, 7.4-12.9) in the pazopanib arm compared with 4.2 months (95% confidence interval, 2.8-4.2) in the placebo arm. The most common side effects include diarrhea, hair color change, hypertension, nausea, fatigue, anorexia, vomiting, dysgeusia, elevated alanine aminotransferase, elevated aspartate aminotransferase, and abdominal pain. The objective of this article is to summarize the scientific review of the application that led to approval in the European Union.

Gastrointestinal (GI) events have been described with sorafenib, sunitinib and pazopanib in cancer patients. We performed an up-to-date meta-analysis to determine the incidence and relative risk (RR) in patients with cancer treated with these agents. PubMed databases were searched for articles published till May 2013. Eligible studies were selected according to PRISMA statement. Summary incidence, RR, and 95% CIs were calculated using random-effects or fixed-effects models based on the heterogeneity of selected studies. A total of 6,447 patients were available for the meta-analysis; 2,260 had renal cell carcinoma (RCC) and 4,187, 1,691 non-small cell lung cancers, 599 hepatocellular cancers, 1,066 breast cancers, 165 neuroendocrine tumors, 304 gastrointestinal stromal tumors and 362 soft tissue sarcomas. Diarrhea was the most common GI event. When stratified by tumor type (RCC vs. non-RCC), the difference among the incidences of GI events was significant for diarrhea (p < 0.001) and vomiting (p = 0.006), that resulted higher in RCC patients. In RCC patients, sorafenib registered the lower incidence and RR of all grades GI events. The difference was statistically significant for sorafenib versus sunitinib-related all and high-grade events (p < 0.001) and for sorafenib versus pazopanib all grades GI events (p < 0.001) and high-grade anorexia (p < 0.001). Treatment with VEGFR TKIs sorafenib, sunitinib and pazopanib is associated with a significant increase in the risk of GI events in patients with cancer, and frequent clinical monitoring should be emphasized when managing these three and newer VEGFR TKIs.

We report a rare case of a renal cell carcinoma (RCC) metastasis occupying the cerebellopontine and cerebellomedullary cisterns, and describe an alternative strategy for embolizing hypervascular intracranial tumors. A middle aged patient with a distant history of RCC presented with headaches, nausea, and vomiting, and was found to have an enhancing mass in the left cerebellopontine and cerebellopontine cisterns. The initial surgical resection was aborted due to excessive bleeding. After an unsuccessful attempt at intra-arterial embolization, the patient returned to the operating room and the tumor was devascularized by direct needle puncture Onyx embolization under biplane fluoroscopy. The devascularized tumor was then successfully dissected from the brainstem and adherent lower cranial nerves. In properly selected cases, open surgical direct needle puncture embolization of intracranial vascular tumors under biplane fluoroscopy is a viable alternative devascularization method.
