The bevacizumab experience in advanced renal cell carcinoma
Bevacizumab in combination with interferon alfa is now approved for treatment-naïve advanced renal cell carcinoma (RCC) in both the US and Europe. Its objective response rates of 30% and progression-free survival rates of 9–10 months are comparable to the other approved first-line multityrosine kinase inhibitors, sunitinib and pazopanib. Its advantages include a different toxicity profile and assurance of administration compliance given its intravenous formulation. Enthusiasm for its use is blunted by the increased costs, the potential infusion-related reactions, the associated interferon-related toxicities, and the inconvenience of its nonoral formulation. Further study is warranted to assess its efficacy both as a single agent and in combination with the targeted agents and other immunotherapies. With multiple agents now available for the treatment of advanced RCC, identification of patient and tumor-specific biomarkers to inform our choice of first-line therapy and the proper sequence of subsequent therapies is imperative

Response to single agent PD-1 inhibitor after progression on previous PD-1/PD-L1 inhibitors: a case series
Background: Monoclonal antibodies targeting the PD-1/PD-L1 axis have gained increasing attention across many solid tumors and hematologic malignancies due to their efficacy and favorable toxicity profile. With more than 1 agent now FDA-approved in a wide variety of tumor types, and with others in clinical trials, it is becoming more common that patients present to clinic for potential treatment with a second PD-1/PD-L1 inhibitor. Case presentation: In this report, we present two patients with renal cell carcinoma and one with melanoma who received PD-1/PD-L1 inhibitors. Upon progression on their first-line PD-1/PD-L1 inhibitors, these patients received a different PD-1 inhibitor (nivolumab in all cases) and all had progressive disease as their best response to the subsequent PD-1 inhibitor. The reported clinical information focuses on the course of the disease and the responses to all treatment regimens. Conclusions: Clinicians should refrain from using multiple PD-1/PD-L1 inhibitors sequentially outside of clinical trials until there is sufficient data to support this practice routinely. Prospective studies that allow prior treatment with PD-1/PD-L1 are needed to validate the efficacy and safety of these drugs in the second line or later setting. Furthermore, ongoing efforts that aim to identify mechanisms of resistance to immunotherapy will be informative and may ultimately assist physicians in select the optimal treatment following progression on PD-1/PD-L1 inhibitor
Nomogram-based Prediction of Overall Survival in Patients with Metastatic Urothelial Carcinoma Receiving First-line Platinum-based Chemotherapy: Retrospective International Study of Invasive/Advanced Cancer of the Urothelium (RISC)
The available prognostic models for overall survival (OS) in patients with metastatic urothelial carcinoma (UC) have been derived from clinical trial populations of cisplatin-treated patients
Scalable whole-exome sequencing of cell-free DNA reveals high concordance with metastatic tumors
Whole-exome sequencing of cell-free DNA (cfDNA) could enable comprehensive profiling of tumors from blood but the genome-wide concordance between cfDNA and tumor biopsies is uncertain. Here we report ichorCNA, software that quantifies tumor content in cfDNA from 0.1× coverage whole-genome sequencing data without prior knowledge of tumor mutations. We apply ichorCNA to 1439 blood samples from 520 patients with metastatic prostate or breast cancers. In the earliest tested sample for each patient, 34% of patients have ≥10% tumor-derived cfDNA, sufficient for standard coverage whole-exome sequencing. Using whole-exome sequencing, we validate the concordance of clonal somatic mutations (88%), copy number alterations (80%), mutational signatures, and neoantigens between cfDNA and matched tumor biopsies from 41 patients with ≥10% cfDNA tumor content. In summary, we provide methods to identify patients eligible for comprehensive cfDNA profiling, revealing its applicability to many patients, and demonstrate high concordance of cfDNA and metastatic tumor whole-exome sequencing
