Which of the following is NOT a type of CINV?

Cumulative is not recognized as a distinct type of chemotherapy-induced nausea and vomiting (CINV). The primary classifications of CINV are acute, delayed, and anticipatory.

Acute CINV typically occurs within the first 24 hours after chemotherapy administration, while delayed CINV occurs later, often between 1 to 7 days after treatment. Anticipatory CINV is a learned response that happens when a patient begins to feel nausea or vomiting before receiving chemotherapy, often triggered by prior experiences or cues associated with treatment.

Cumulative, while it might describe an accumulation of effects or symptoms over multiple cycles of treatment, does not stand alone as a specific, recognized type of CINV within the clinical framework. Understanding these distinct classifications is critical for effective management and prevention strategies in patients undergoing chemotherapy.
