Hepatic toxicity during regorafenib treatment in patients with metastatic gastrointestinal stromal tumors.

Regorafenib is a multi-target tyrosine kinase inhibitor that has been approved for the treatment of metastatic colorectal cancer, advanced hepatocellular carcinoma, and metastatic gastrointestinal stromal tumors (GIST). Severe hepatobiliary toxicity has been reported in patients with colorectal cancer treated with regorafenib, but not in those with GIST. Therefore, the aim of the present study was to investigate the incidence and clinical course of regorafenib-associated hepatic toxicity (HT) in patients with GIST in a real-world setting.

Predictive Factors for Second-Line Therapy in Metastatic Renal Cell Carcinoma: A Retrospective Analysis.

Currently, about 50% of patients with metastatic renal cell carcinoma (mRCC) receive a second-line therapy. Therefore, the choice at each subsequent treatment line remains an important issue. In this retrospective study, we sought to identify pretreatment clinical parameters that could predict the likelihood of a patient receiving a second-line therapy.

Efficacy and safety of gemcitabine, oxaliplatin, and paclitaxel in cisplatin-refractory germ cell cancer in routine care--Registry data from an outcomes research project of the German Testicular Cancer Study Group.

Background: Chemotherapy (CTX) with gemcitabine, oxaliplatin, and paclitaxel (GOP) has demonstrated efficacy with an overall response rate (ORR) of approximately 50% in patients with multiply relapsed or cisplatin-refractory germ cell cancer (GCC) or both within a phase II study. We analyzed the efficacy and safety of GOP in routine clinical practice within a registry of the German Testicular Cancer Study Group.

Methods: Overall, 63 patients with refractory GCC, who received GOP because of progression under cisplatin-based treatment or relapse after high-dose CTX, were included in this database.
