Nausea and vomiting are common in cancer patients. The most common cause of nausea and vomiting is the administration of cytotoxic chemotherapy. Apart from chemotherapy-induced nausea and vomiting (CINV), biological agents may also cause these symptoms. ⋯ The cornerstone of effective management of nausea and vomiting secondary to these antineoplastic drugs is the prevention with the use of appropriate guideline-directed combination antiemetic regimen. Type 3 serotonin receptor antagonists (5HT3RAs), neurokinin-1 receptor antagonists (NK1RAs), and dexamethasone are the backbone antiemetic drugs. In recent years, newer drugs and preparations have been introduced for clinical use and include second-generation 5HT3RA, palonosetron; granisetron transdermal patch; the recently introduced NK1RA rolapitant; and the novel oral combined drug NEPA (netupitant plus palonosetron); and last but not least, the atypical antipsychotic olanzapine.

ReviewOctreotide and Lanreotide in Gastroenteropancreatic Neuroendocrine Tumors.
Neuroendocrine tumors are heterogeneous, rare malignancies that arise most commonly in the gastrointestinal tract and pancreas. They often secrete vasoactive substances resulting in carcinoid syndrome and the tumor cells exclusively express somatostatin receptors. ⋯ We discuss the available data to support their use as symptom controlling and antiproliferative agents. This article also reviews the guidelines (National Comprehensive Cancer Network and North American Neuro Endocrine Tumor Society), cost-analysis (suggesting the cost-effectiveness of lanreotide autogel compared to higher doses of octreotide long acting release formulation in refractory patients), and future directions of somatostatin analogs in the management of patients refractory to conventional doses of octreotide and lanreotide.
