The use of immune checkpoint inhibitors combined with vascular endothelial growth factor (VEGF)-targeted therapy as second-line treatment for metastatic clear cell renal cancer (mRCC) has not been evaluated prospectively. ⋯ Patients with advanced kidney cancer whose disease had worsened during treatment with atezolizumab or sunitinib began second-line treatment with atezolizumab + bevacizumab. Tumors shrank in more than one-quarter of patients treated with this combination, and side effects were manageable.

Cyclic high-dose testosterone injections, also known as bipolar androgen therapy (BAT), is a novel treatment strategy for patients with metastatic castration-resistant prostate cancer (mCRPC). BAT has shown clinical activity in prior studies enrolling men with mCRPC and may potentially restore sensitivity to prior androgen receptor (AR)-targeted agents. ⋯ BAT is well tolerated in metastatic castration-resistant prostate cancer patients. The type of prior AR-targeted therapy might affect response to BAT as well as AR-therapy rechallenge. BAT followed by AR-targeted therapy rechallenge did not improve outcomes in AR-V7-positive patients.

To improve the prognosis of upper tract urothelial carcinoma (UTUC), clinicians have used neoadjuvant chemotherapy (NAC) or adjuvant chemotherapy (AC) before or after radical nephroureterectomy (RNU). Despite some new data, the evidence remains mixed on their efficacy. ⋯ After a comprehensive search of the latest studies examining the role of neoadjuvant and adjuvant chemotherapy for upper tract urothelial cancer, the pooled evidence shows that perioperative chemotherapy was beneficial for prolonging survival; however, the evidence for adjuvant chemotherapy was stronger than that for neoadjuvant chemotherapy.
