This review focuses on the newest data on mechanistic aspects of chemotherapy-induced peripheral neuropathy (CIPN), its assessment and the current status of neuroprotection and treatment options. ⋯ CIPN is a common, potentially severe and dose-limiting adverse effect of cancer treatment. Chemotherapies mainly target axons, dorsal root ganglia and terminal trees of intraepidermal nerve fibers. A quick and noninvasive method allowing the assessment of CIPN should be developed, although no treatment prevents CIPN or improves its long-term course. Furthermore, symptomatic therapy is often largely ineffective in reducing CIPN symptoms.

To review the latest preclinical and clinical findings on the role of cyclin-dependent kinase 4 and 6 (CDK4/6) inhibitors in breast cancer and update on the studies investigating the predictive biomarkers of response to CDK4/6 inhibitors. ⋯ Target therapies have brought great improvements in the management of breast cancer patients. CDK4/6 inhibitors look promising in the treatment of patients with hormone-receptor-positive breast cancer, but it is of pivotal importance to identify which subgroup of patients would mostly benefit from CDK4/6 inhibition with biomarker-driven clinical trials.

The purpose of this review is to assess recent evidence that demonstrates that aspirin has the potential to be an effective preventive and therapeutic agent in gastrointestinal malignancy. ⋯ These findings have re-awakened interest in the role of aspirin in the primary prevention of cancer and in the treatment of cancer. Randomized controlled trials are underway to assess the role of aspirin within the treatment algorithms of several solid common cancers.

The purpose of this review is to provide an update on palliative sedation in palliative and end-of-life care. Palliative sedation is the medical procedure used to deal with refractory symptoms in advanced cancer patients when all other specific approaches have failed. ⋯ To maintain palliative sedation as a legitimate clinical procedure from any ethical or clinical point of view, it must be limited to the restricted area for which it was conceived, that is, relief from refractory suffering as deemed necessary by a patient and by an experienced palliative care team. In this way, there is no risk of associating palliative sedation with other end-of-life decisions. Close collaboration is needed between oncologists and palliative care physicians for this clinical procedure.

Next generation sequencing (NGS) allows the rapid analysis of genomes and has brought invaluable information on cancer biology and drug targets. Laboratories have started to provide NGS data to physicians to aid in the prescription of targeted drugs. The review presents the recent clinical experience with NGS. ⋯ NGS and other molecular technologies are transforming the practice of medical oncology and clinical research. Sequencing of primary tumors, metastases, or blood-derived circulating tumor DNA has great potential to guide individualized cancer treatment. However, the integration of NGS as a breakthrough technology is associated with operational challenges such as information processing, medical education and interpretation, and reimbursement.
