AbstractIntroductionNasal symptoms are frequently reported by patients undergoing chemotherapy.MethodsEligible patients planning to receive paclitaxel, docetaxel, nab‐paclitaxel, bevacizumab without a concomitant taxane, or “other” (non‐taxane, non‐bevacizumab) chemotherapy regimens were invited to participate in this prospective study. Patients reported nasal symptoms prior to each dose of chemotherapy.ResultsThe percentage of patients (95% CI) who reported nasal symptoms was the same for patients who received bevacizumab or nab‐paclitaxel, 82.6% (61.2%, 95.1%). There were no significant differences among the proportions of patients experiencing nasal symptoms within the paclitaxel, nab‐paclitaxel, and bevacizumab cohorts. Patients in the nab‐paclitaxel cohort were more likely to experience symptoms than those in the non‐taxane non‐bevacizumab cohort or docetaxel cohort (p = 0.001, p = 0.001). Patients in the bevacizumab cohort were more likely to experience nasal symptoms than those in the non‐taxane non‐bevacizumab cohort (p = 0.03).ConclusionNasal vestibulitis symptoms are common in patients receiving chemotherapy, especially those receiving paclitaxel, docetaxel, and bevacizumab. Further investigations into treatments of this symptom complex are warranted.

e24086 Background: Nasal vestibulitis has been infrequently described as a side effect of cancer-directed therapy; however, a preliminary study reported that 71% of patients undergoing taxane chemotherapy experienced nasal vestibulitis symptoms. This natural history trial describes the incidence, characteristics, and severity of nasal vestibulitis symptoms among patients undergoing paclitaxel, docetaxel, and non-taxane chemotherapy. Methods: Eligible participants who reported baseline (prior to starting chemotherapy) nasal symptoms ≤ 2 on a 10-point scale were enrolled in this trial upon initiation of a new treatment regimen, involving paclitaxel or docetaxel, or non-taxane chemotherapy. Participants completed nasal symptom logs each time they received a dose of therapy until either the regimen was stopped or four months had passed. The proportion of patients reporting new nasal symptoms was estimated within each cohort with the 95% exact confidence interval (CI). A cumulative incidence model was utilized to quantify the incidence of treatment-emergent nasal symptoms within each cohort, while controlling for age, sex, smoking history, and history of asthma or allergies. Results: Thirty-five participants received paclitaxel, 21 received docetaxel, and 25 received other types of chemotherapy. 86.4% of participants were female, mean age was 60.2 ± 11.2 years; 93.8% of participants completed 2 or more surveys. A higher percentage of participants in the paclitaxel cohort experienced new nasal vestibulitis symptoms than participants in the other two cohorts. The percentage (95% CI) of participants with nasal symptoms, for patients receiving paclitaxel, docetaxel, and non-taxane chemotherapy were 74.3% (56.7%, 87.5%), 47.6% (25.7%, 70.2%), and 44.0% (24.4%, 65.1%), respectively. Epistaxis was reported by 60% of participants in the paclitaxel cohort. Paclitaxel-receiving participants also reported nasal dryness (48.6%), scabbing (40.0%), and pain (20.0%). Nearly half of participants reported moderate symptoms (4-7 out of a 10-point scale), with 8.6% reporting symptoms as severe (8-10 on a 10-point scale). Conclusions: Nasal vestibulitis is a common side effect of chemotherapy, especially paclitaxel chemotherapy.
