Cutaneous toxicities associated with EGFR inhibitors (EGFRIs) have a significant impact on patient treatment continuation, quality of life and healthcare resource utilization. This paper reviews the current prophylaxis and management of EGFRI-induced cutaneous toxicities in patients with colorectal cancer, and combines these findings with the authors' clinical expertise to define a novel algorithm for healthcare professionals managing patients receiving EGFRIs. This tool includes a grading system based on the location, severity and psychological impact, and provides a standard prescription pack, advice on prophylaxis/self-management of cutaneous symptoms for patients initiating EGFRIs, and essential guidance on subsequent review and treatment escalation. It aims to optimize treatment of metastatic colorectal cancer by minimizing cutaneous toxicities to maintain dose intensity and efficacy of EGFRI-based chemotherapy.

Epithelial ovarian cancer (EOC) remains a leading cause of cancer death in women. Approximately 10-15% of patients with EOC harbor a genetic predisposition due to mutations in BRCA1/2 genes. ⋯ In the pivotal Phase III NOVA trial, maintenance therapy post platinum response with niraparib significantly improved outcomes in all subgroups, leading to the first polyadenosine diphosphate-ribose polymerase inhibitors approval by the US FDA in this setting. In this review, we will focus on the role of niraparib in the treatment of EOC.

Regorafenib is an orally available multikinase inhibitor, currently approved in metastatic chemorefractory colorectal cancer patients. The results of two large randomized Phase III trials are available, providing significant results in overall and progression-free survival in this situation. ⋯ Identifying patients who will tolerate and have benefit from regorafenib is a challenge for clinicians. Therapeutic monitoring (especially cfDNA), predictive biomarkers and specific perfusion-based imaging techniques will may be result in optimizing regorafenib treatment.

To perform a systematic review of the relevant literature about clinical trials on efficacy and safety of immune checkpoint inhibition, whether it is used alone, in combination or with other targeted therapies in patients with advanced and metastatic renal cell carcinoma (RCC), two team members reviewed the abstracts and selected pertinent articles from the relevant databases. A narrative review of randomized controlled trials was performed and seven randomized controlled trials were identified in this systematic review. In treatment of RCC, nivolumab has superior efficacy and safety compared with second-line everolimus. Combination strategies, especially those combined with anti-VEGF agents presents better efficacy but worse outcomes in term of safety than monotherapy and conventional treatment and might guide treatment choice for patients with RCC.

Nivolumab is a PD-1 inhibitor approved for the use in treatment of multiple tumor types (such as melanoma, non-small-cell lung cancer, renal cell carcinoma, urothelial cancer and Hodgkin's lymphoma). In July 2017, the US FDA granted accelerated approval of this agent for the treatment of metastatic colorectal cancer patients whose tumor harbors deficient mismatch repair, or microsatellite-instability high and have progressed on conventional chemotherapy. In this review, we will discuss the use, efficacy, and safety of this agent in microsatellite-instability high metastatic colorectal cancer.
