73 m(2)) was identified in 65 patients (26.7%), including 26.7%,27.1% and 26.8% who underwent radio frequency ablation, partial nephrectomy and radical nephrectomy, respectively. Following intervention the 3-year freedom from a glomerular filtration rate decrease of below 60 ml per minute per 1.73 m(2) for radio frequency ablation, partial nephrectomy and radical nephrectomy was 95.2%, 70.7% and 39.9%, respectively (p <0.001). Multivariate analysis showed that radical nephrectomy was an independent risk factor vs radio frequency ablation and partial nephrectomy for stage 3 chronic kidney disease (HR 34.3, 95% CI 4.28-275 and

10.9, 95% CI 1.36-88.7, respectively).

Conclusions: learn more Decreased renal function is prevalent in patients with small unilateral renal tumors even with a normal contralateral kidney. Ablative or extirpative nephron sparing techniques are effective for preserving renal function in these patients.”
“Purpose: Antiangiogenic therapy with sunitinib and sorafenib has become the standard of care for patients with advanced renal cell carcinoma. However, the clinical benefit of these agents after prior antiangiogenic therapy has not been defined. Currently, several agents with a putative antiangiogenic mechanism exist and they are often being used in sequence with little to no data regarding

activity in a second line or later setting.

Materials and Methods: Patients with advanced renal cell carcinoma currently being treated with either sunitinib or sorafenib after receiving Apoptosis antagonist I or more prior antiangiogenic agent(s) were investigated in a retrospective analysis. Time to progression and the overall response rate by Response Evaluation Criteria in Solid Tumors were evaluated.

Results: Thirty patients receiving current sunitinib

(16 patients) or sorafenib (14 patients) were identified. Patients received 1 or more prior antiangiogenic therapies: thalidomide, lenalidomide, bevacizumab, volociximab, AG13736, sorafenib or sunitimb. Of 16 patients treated with sunitinib 13 had some degree of tumor shrinkage, including 9 with a partial response by Response Evaluation Criteria in Solid Cytidine deaminase Tumors. Of 14 patients treated with sorafenib 10 had some degree of tumor shrinkage, including 1 with a partial response. The median time to progression for the entire cohort was 10.4 months.

Conclusions: Significant antitumor activity is observed when sorafenib or sunitinib are used in patients who have failed prior therapy with an antiangiogenic agent. Prior response to an antiangiogenic agent does not appear to predict subsequent clinical benefit to either sunitinib or sorafenib.”
“Purpose: The most common approach for nonmuscle invasive urothelial cancers of the bladder is transurethral resection of the bladder tumor, often under regional or general anesthesia.
