Abstract 2078P
Background
Chemotherapy-induced nausea and vomiting (CINV) occurs in two arbitrarily defined phases: the acute phase (from 0 to 24 h following chemotherapy (CT) initiation) and the delayed phase (from 24 to 120 h). Almost all antiemetic studies have therefore evaluated efficacy to 120 h after the administration of CT, and the period beyond 120 h is generally perceived to be relatively free of CINV, with some studies reporting continued nausea beyond the delayed phase.
Methods
In July and September of 2022, healthcare providers (HCPs) in Japan were recruited to complete an online quantitative survey. All HCPs were required to work with patients receiving anticancer CT in the hospital setting and have experience selecting, preparing and/or administering antiemetics. As part of this survey responses were collected on whether HCPs had patients who experienced nausea/vomiting (CINV) during Days 5-7 (beyond the delayed phase) after initiation of CT. Responses were also captured by CT regimen; for the physician subset, respondents were grouped by and analyzed only if they were prescribers of the chemotherapy type.
Results
A total of 809 HCPs (174 pharmacists, 102 nurses and 533 physicians) completed the survey. The physician group was comprised of breast surgeons (n = 57), pulmonologists (n = 107), gastroenterologists (n = 74), GI surgeons (89), gynecologists (n = 98), ENTs (n = 54), and oncologists (n = 54). The vast majority of respondents (98%, 93%, and 88% of pharmacists, nurses, and physicians, respectively) indicated they had patients who experienced CINV 5-7 days after CT. Of the HCPs reporting patients with CINV on Days 5-7, the highest proportions were seen for cisplatin, AC and EC chemotherapy regimens (Table). Table: 2078P
Proportions of respondents with patients experiencing CINV on days 5-7 by chemotherapy regimen
CT Regimen | Pharmacists | Nurses | Physician Prescribers |
Cisplatin | 78% | 71% | 80% |
Epirubicin/cyclophosphamide (EC) | 50% | 43% | 43% |
Anthracycline/cyclophosphamide (AC) | 44% | 45% | 42% |
Carboplatin | 37% | 43% | 48% |
Irinotecan | 41% | 37% | 37% |
Oxaliplatin | 36% | 32% | 28% |
Conclusions
This survey highlights a need for continued assessment of CINV beyond the delayed phase after CT to better understand the incidence and to optimize prevention of CINV for the entire period of risk.
