Efficacy and safety of pembrolizumab in patients with advanced urothelial carcinoma deemed potentially ineligible for platinum-containing chemotherapy: Post hoc analysis of KEYNOTE-052 and LEAP-011.

Background: First-line pembrolizumab monotherapy is a standard of care for platinum-ineligible patients with advanced urothelial carcinoma (UC). No global standardized definition of platinum ineligibility exists. This study aimed to evaluate the efficacy and safety of pembrolizumab monotherapy in patients with UC who met various criteria for platinum ineligibility.

Molecular Biomarkers of Prognosis in Advanced Renal Cell Carcinoma Patients Treated With Pazopanib Plus Interferon Alpha (INF-2A) in a Phase I/II Study by the Spanish Oncology Genitourinary Group.

Introduction: The therapeutic repertoire available for advanced renal cell carcinoma (RCC), including tyrosine kinase inhibitors (TKIs) and immunotherapy, required for molecular biomarkers for response.

Patients And Methods: This was a phase I to II trial on the combination of pazopanib with interferon-alpha (INF-2A) as first-line treatment for advanced RCC. The primary endpoint was recommended phase II dose (RP2D) and efficacy in terms of objective response rate (ORR, RECIST 1.

Results of the FLAC European Database of Metastatic Castration-Resistant Prostate Cancer Patients Treated With Docetaxel, Cabazitaxel, and Androgen Receptor-Targeted Agents.

Background: Several agents have demonstrated an overall survival (OS) benefit in patients with metastatic castration-resistant prostate cancer (mCRPC); however, the optimal sequencing of these therapies is unknown as a result of a lack of prospective randomized controlled trials. This retrospective study aimed to identify clinical factors influencing outcomes and to determine optimal treatment sequencing in patients with mCRPC treated with cabazitaxel (CABA) and/or androgen receptor-targeted agents (ART) after androgen-deprivation therapy (ADT) and docetaxel (DOC).

Patients And Methods: Records of 574 consecutive patients treated (2012-2016) at 44 centers in 6 countries were retrospectively examined.

Deep sequencing reveals microRNAs predictive of antiangiogenic drug response.

The majority of metastatic renal cell carcinoma (RCC) patients are treated with tyrosine kinase inhibitors (TKI) in first-line treatment; however, a fraction are refractory to these antiangiogenic drugs. MicroRNAs (miRNAs) are regulatory molecules proven to be accurate biomarkers in cancer. Here, we identified miRNAs predictive of progressive disease under TKI treatment through deep sequencing of 74 metastatic clear cell RCC cases uniformly treated with these drugs.

Phase II clinical trial of PM00104 (Zalypsis(®)) in urothelial carcinoma patients progressing after first-line platinum-based regimen.

Purpose: This exploratory phase II clinical trial evaluated the antitumor activity, safety profile and pharmacokinetics of PM00104 (Zalypsis(®)) 3 mg/m(2) 1 h every 3-week intravenous infusion in patients with advanced and/or metastatic urothelial carcinoma progressing after first-line platinum-based chemotherapy.

Methods: The primary efficacy end point was the disease control rate (DCR), defined as the percentage of patients with confirmed objective response or progression-free at 3 months, according to the response evaluation criteria in solid tumors.

Results: In a first stage (n = 19 patients evaluable for efficacy), only one patient achieved DCR (stable disease as best response and progression-free survival of 3.

Single nucleotide polymorphism associations with response and toxic effects in patients with advanced renal-cell carcinoma treated with first-line sunitinib: a multicentre, observational, prospective study.

Background: Sunitinib is a tyrosine kinase inhibitor with proven efficacy in renal-cell carcinoma, but some patients do not respond or need dose reductions due to toxicity. Because there are no validated molecular predictors of response or toxicity to sunitinib, we aimed to identify genetic markers predictive of outcome and toxic effects.

Methods: In our observational, prospective study we enrolled previously untreated adults (≥ 18 years) with clear-cell renal-cell carcinoma at 15 institutions in the Spanish Oncology Genitourinary Group in Spain.
