Treatment-related adverse events (AEs) are common in patients with metastatic colorectal cancer (mCRC) receiving chemotherapy. These AEs may affect patient adherence, particularly with completely oral regimens, such as trifluridine/tipiracil (TAS-102, Lonsurf®), an antimetabolite agent for patients with mCRC refractory or intolerant to standard therapies. . ⋯ Oncology nurses play an important role in educating and counseling patients regarding treatment and its potential side effects. Among patients with mCRC refractory or intolerant to standard therapies, trifluridine/tipiracil was found to have a favorable safety profile. It is associated with hematologic AEs as well as a low incidence of nausea, diarrhea, vomiting, anorexia, and fatigue.

ReviewGinger-Mechanism of action in chemotherapy-induced nausea and vomiting: A review.
Despite advances in antiemetic therapy, chemotherapy-induced nausea and vomiting (CINV) still poses a significant burden to patients undergoing chemotherapy. Nausea, in particular, is still highly prevalent in this population. Ginger has been traditionally used as a folk remedy for gastrointestinal complaints and has been suggested as a viable adjuvant treatment for nausea and vomiting in the cancer context. ⋯ These properties include 5-HT3, substance P, and acetylcholine receptor antagonism; antiinflammatory properties; and modulation of cellular redox signaling, vasopressin release, gastrointestinal motility, and gastric emptying rate. This review outlines these proposed mechanisms by discussing the results of clinical, in vitro, and animal studies both within the chemotherapy context and in other relevant fields. The evidence presented in this review indicates that ginger possesses multiple properties that could be beneficial in reducing CINV.

Rolapitant is a highly selective neurokinin-1 receptor antagonist, orally administered for a single dose of 180 mg before chemotherapy with granisetron D1, dexamethasone 8 mg BID on day 2-4. It has a unique pharmacological characteristic of a long plasma half-life (between 163 and 183 hours); this long half-life makes a single use sufficient to cover the delayed emesis risk period. No major drug-drug interactions between rolapitant and dexamethasone or other cytochrome P450 inducers or inhibitors were observed. ⋯ The primary endpoint was the proportion of patients achieving a complete response (defined as no emesis or use of rescue medication) in the delayed phase (>24-120 hours after chemotherapy). In comparison to granisetron (10 μg/kg intravenously) and dexamethasone (20 mg orally) on day 1, and dexamethasone (8 mg orally) twice daily on days 2-4 and placebo, rolapitant showed superior efficacy in the control of delayed and overall emesis. This review aims at revising the pharmacological characteristics of rolapitant, offering an updated review of the available clinical efficacy and safety data of rolapitant in different clinical settings, highlighting the place of rolapitant in the management of chemotherapy-induced nausea and vomiting (CINV) among currently available guidelines, and exploring the future directions of CINV management.

Review Comparative StudyRolapitant for the prevention of delayed nausea and vomiting over initial and repeat courses of emetogenic chemotherapy.
Chemotherapy-induced nausea and vomiting (CINV) is a debilitating side effect of many cytotoxic chemotherapy regimens. Although sustained antiemetic control across repeated chemotherapy cycles is important for cancer treatment continuation, few studies have investigated the efficacy of antiemetic prophylaxis over multiple chemotherapy cycles. ⋯ Rolapitant shows sustained control of emesis and nausea over multiple cycles of chemotherapy, and compared to other NK-1 receptor antagonists, has a longer half-life and reduced potential for cytochrome P450 3A4-mediated drug-drug interactions. Expert commentary: Trial design should be a key consideration in future studies of CINV therapies, including analytical methods utilized, choice of endpoints, and methods for accounting for nonresponders and patient attrition over multiple cycles of chemotherapy.

ReviewRolapitant: An NK-1 Receptor Antagonist for the Prevention of Chemotherapy- Induced Nausea and Vomiting.
Nausea and vomiting are among the most feared side effects of chemotherapy and can prevent cancer patients from completing their treatment regimens. Rolapitant is a highly selective neurokinin-1 (NK-1) receptor antagonist with very good oral activity, central nervous system penetration and a long (180-hour) plasma half-life. Unlike other available NK-1 receptor antagonists, rolapitant does not inhibit or induce cytochrome P450 (CYP) 3A4. ⋯ Rolapitant's favorable toxicity profile and lack of CYP3A4-related drug-drug interactions indicate that it would be a suitable treatment for older patients or those with multiple comorbidities, who are likely to be receiving a number of concomitant medications. Future studies should focus on the role of rolapitant in the control of chemotherapy-induced nausea and vomiting in patients receiving multiple-day chemotherapy, specific chemotherapy agents or high-dose chemotherapy and stem cell support.
