What chemo drugs are highly emetogenic?
High risk: Emesis has been documented in more than 90% of patients:Anthracycline/cyclophosphamide combination.Carmustine.Cisplatin.Cyclophosphamide (≥1,500 mg/m2).Dacarbazine.Dactinomycin.Mechlorethamine.Streptozotocin.
Which chemo has the highest emetogenic potential?
Irinotecan-based chemotherapy regimens have high emetogenic potential and require optimized antiemetic prophylactic therapy, according to a study published in Supportive Care in Cancer. Chemotherapy-induced nausea and vomiting (CINV) is one of the biggest challenges faced during anticancer treatment.
What is emetogenic risk?
Emetogenicity: the propensity of an agent to cause nausea, vomiting or retching. High emetic potential: greater than 90% frequency of emesis in the absence of effective prophylaxis. Moderate emetic potential: 30 to 90% frequency of emesis in the absence of effective prophylaxis.
Why do chemo patients vomit?
Why Does Chemo Make You Sick? Your body sees the medicine as foreign. It sets off warning signals in your brain and digestive system. This flips the on switch in a part of your brain called the vomiting center.
What works best for chemo nausea?
Eat bland foods, such as dry toast and crackers. Eat food cold or at room temperature to decrease its smell and taste. Avoid fatty, fried, spicy, or very sweet foods. Try small amounts of foods high in calories that are easy to eat (such as pudding, ice cream, sherbets, yogurt, and milkshakes) several times a day.

Why does potassium drop during chemo?
Low potassium or hypokalemia: Potassium is lost from the gut during dehydration resulting from diarrhea as a result of chemotherapy.
What is emetogenic surgery?
FIGURE PONV = postoperative nausea and vomiting; Emetogenic surgery = surgery with a high risk for PONV e.g., intra-abdominal surgery, gynecologic surgery, breast surgery, strabismus surgery, and ENT surgery.

Is Methotrexate highly emetogenic?
Conclusions: The poor complete CINV control rate in children receiving methotrexate confirms the classification of HD-MTX as highly emetogenic chemotherapy (HEC) and suggests that ID-MTX be reclassified as HEC.
What part of the brain is associated with vomiting?
The area postrema (AP) has been implicated as a chemoreceptor trigger zone for vomiting (emesis) for over 40 years. The AP is located on the dorsal surface of the medulla oblongata at the caudal end of the fourth ventricle.
Which of the following combinations is highly emetogenic?
Summary: The major guideline groups recommend a combination of a 5-HT3 receptor antagonist, dexamethasone and aprepitant ('triple therapy') for treatment categorized as highly emetogenic.
Is folfox highly emetogenic?
FOLFOX is a moderately emetogenic chemotherapy regimen associated with a significant amount of delayed CINV that remains difficult to control even using standard antiemetic therapy [10].
Is cyclophosphamide highly emetogenic?
Combined anthracycline and cyclophosphamide regimens have been recently reclassified as highly emetogenic chemotherapy regimen.
Is carboplatin highly emetogenic?
The NCCN has recently reclassified carboplatin emetogenicity according to the AUC (target area under the concentration versus time curve) with a carboplatin AUC ≥4 classified as highly emetogenic and carboplatin AUC < 4 as moderately emetogenic - but highly emetogenic in certain patients.
How long does it take for emetic to resolve after chemo?
All efforts to date to define emetogenic schemas for chemotherapy agents have concentrated on the potential for emesis within the first 24 h (acute emesis). This is appropriate given the potential severity of uncontrolled acute emesis and the observation that emesis induced by many chemotherapy agents will resolve within 24 h. For a classification schema to be most relevant and serve as a basis for treatment recommendations, however, it must also account for the ability of certain chemotherapy agents to produce emesis beyond the 24-h period following chemotherapy, so-called “delayed emesis.” Cisplatin is the classic agent by which delayed emesis has been defined. In the absence of appropriate antiemetic prophylaxis, there is an approximate 65%-90% likelihood of delayed emesis following administration of cisplatin [ 23 - 25 ]. A number of other agents, including cyclophosphamide, carboplatin, and doxorubicin, also have the potential to induce delayed emesis. Although the risk of delayed emesis is less than with cisplatin, up to one-third of patients receiving these agents will experience delayed emesis in the absence of delayed antiemetic prophylaxis [ 26 ].
How does emesis affect quality of life?
Inadequately controlled emesis significantly impairs quality of life and increases the risk of patient non-compliance with therapy. Substantial progress has been made over the last decade in developing more effective and better tolerated means to prevent chemotherapy-induced emesis [ 3 ]. Several factors have contributed to ...
What are the factors that determine antiemetic risk?
Some of these factors relate to the patient population (age, gender, history of ethanol consumption, and prior experience with chemotherapy), and some relate to the treatments administered.
What is the most significant development in cancer chemotherapy?
The most significant development has been the introduction of a new class of antiemetic agents, the selective antagonists of the type 3 serotonin receptor.
What is NCCN guidelines?
The NCCN guidelines are a statement of consensus of its authors regarding their views of currently accepted approaches to treatment. Any clinician seeking to apply or consult any NCCN guideline is expected to use independent medical judgment in the context of individual clinical circumstances to determine any patient's care or treatment. The National Comprehensive Cancer Network makes no warranties of any kind whatsoever regarding their content, use, or application and disclaims any responsibility for their application or use in any way.
Is emetogenicity predictive of chemo?
Substantial progress has been realized over the last 15 years in predicting the risk of emesis following cancer chemotherapy. Of the known predictive factors, the intrinsic emetogenicity and pattern of emesis have emerged as the most clinically relevant. A better understanding of the latter factors has allowed the development of rational guidelines to help assist the clinician in using antiemetic agents in the most rational and cost effective manner possible. Efforts should continue to develop more comprehensive emetogenic schemas that attempt to take into account all of the known patient- and treatment-related factors.
Is Cisplatin an emetogenic agent?
Efforts to develop additional useful antiemetic agents to address unmet needs (delayed emesis, high-dose chemotherapy, and multi-day chemotherapy) are continuing. Cisplatin has traditionally served as the gold standard emetogenic challenge in new agent development. As cisplatin use declines, however, the ability to evaluate new agents in a timely manner has become an increasing challenge. An emetogenic classification schema that allows more precision in defining emetic risk, particularly in “high-risk” patient categories, could potentially facilitate new antiemetic agent development.
What is the incidence of CINV in a patient with cisplatin?
Results showed that patients who received cisplatin and anthracycline-cyclophosphamide combination therapy, regimens classified as HEC, had CINV incidence of 37.5% and 54.4% , respectively.
