CINV stands for chemotherapy-induced nausea and vomiting - common, yet potentially preventable, side effects of chemotherapy.

 WHAT IS CINV?

CINV stands for chemotherapy-induced nausea and vomiting - common, yet potentially preventable, side effects of chemotherapy. Chemotherapy is a type of cancer treatment that uses drugs to destroy cancer cells. Approximately 70-80% of patients who do not receive appropriate preventative treatment will experience CINV.

Types of CINV

-    Acute vomiting refers to symptoms that occur within 24 hours of the administration of chemotherapy.

-    Delayed vomiting refers to vomiting 2-5 days after the administration of chemotherapy.

-    Anticipatory vomiting is vomiting prior to the administration of chemotherapy. This type of vomiting is more likely in children who have had particularly negative post chemotherapy nausea or vomiting experience.

Could CINV be prevented?

A team approach that includes experts with knowledge about treatments may help patients better prevent their CINV. There are many treatments aimed at preventing CINV; medical guidelines recommend treatment options to prevent CINV for the entire time a patient is at risk for nausea and vomiting.

Why CINV prevention matters?

Both acute and delayed CINV can have a serious impact on patients. One study found 90% of patients who have poorly managed or uncontrolled CINV report a significant impact on their daily functioning.

Medical complications include: poor nutrition, dehydration, electrolyte imbalance and physical/mental deterioration. In some cases, patients may refuse to or unable to continue on their chemotherapy treatment because of CINV.

Besides treatment, there are several things you can do to help prevent nausea and vomiting from chemotherapy. Here are a few tips to try:
