If a patient experiences CINV from 24 hours to 5 days after chemotherapy, it is referred to as?

The term "Delayed CINV" refers to nausea and vomiting that occurs more than 24 hours after chemotherapy administration, typically within a window of 2 to 5 days post-treatment. This type of CINV is distinguished from acute CINV, which occurs within the first 24 hours after chemotherapy. In clinical management, recognizing the timing of CINV is crucial for implementing appropriate prophylaxis and treatment strategies.

Delayed CINV usually affects patients who receive highly emetogenic chemotherapy agents, and awareness of this timing allows healthcare providers to better address the needs of patients. Proactive measures can be taken to prevent or manage these symptoms effectively, thereby improving patients' quality of life during their treatment regimens.

In contrast, acute CINV would pertain to symptoms arising shortly after chemotherapy, while breakthrough CINV refers to symptoms that occur despite prophylactic treatment. Anticipatory CINV involves a conditioned response where patients experience nausea before chemotherapy due to previous experiences with the treatment. Understanding these definitions helps clinicians provide tailored supportive care for patients undergoing chemotherapy.
