Paclitaxel and nanoparticle albumin-bound paclitaxel are known to cause adverse events of eye disorders, such as cystoid macular edema. However, at present, the risk factors remain unclear. Therefore, risk factors for eye disorders caused by paclitaxel and nanoparticle albumin-bound paclitaxel were studied. This retrospective study targeted patients who were newly administered paclitaxel or nanoparticle albumin-bound paclitaxel at Kyoto Okamoto Memorial Hospital between April 1, 2012, and March 31, 2017. Eye disorder occurrence was defined as an event in which the pharmacist confirmed the symptoms in a patient interview and the ophthalmologist diagnosed the disorder. To analyze the risk factors, logistic regression analysis using 41 factors was performed. Of 128 subjects, 13 (10.2%) had eye disorders with symptom degrees of Grades 1 and 2. The symptoms were conjunctivitis or subconjunctival hemorrhage (3.1%), visual acuity reduction (2.3%), blurred vision and eye pain (1.6% each), eye mucus, blepharitis, stye, watering eyes, photopsia, and muscae volitantes (0.8% each). In eight patients, the conditions patients improved with spontaneously or with medication use; no improvements were observed the cases of visual acuity reduction, blurred vision, or muscae volitantes. Multivariate logistic regression analysis revealed that a cumulative dose of ≥819 mg/m 2 (odds ratio: 5.34, 95% confidence interval: 1.32-21.60, p 0.019) and baseline alkaline phosphatase ≥256 U/L (odds ratio: 3.74, 95% confidence interval: 1.02-13.70, p 0.046) were significant risk factors associated with eye disorders. In conclusion, it was determined that paclitaxel-and nanoparticle albumin-bound paclitaxelrelated eye disorders might be influenced by cumulative dose and baseline alkaline phosphatase.
Purpose Docetaxel is known to cause eye disorders. In this study, current status of eye disorders caused by docetaxel administration every 3 weeks in Japanese patients was examined. Methods This case-control study targeted patients who were newly administered docetaxel at the Kyoto Okamoto Memorial Hospital between 1 July 2015 and 30 June 2018. Eye disorder occurrence was defined as an event in which the pharmacist confirmed the symptoms in a patient interview and the ophthalmologist diagnosed the disorder. Results Of the 89 subjects, 7 (7.9%) had eye disorders. The symptoms were watering eyes (7.9%), a stye and eye discharge (2.2% each), corneal and conjunctival disorder, visual acuity reduction, and blepharedema (1.1% each). Four patients who presented with watering eyes, eye discharge, or corneal and conjunctival disorder showed improvement with the use of eye drops such as artificial tears. Two patients who presented with a stye showed improvement with the use of oral cefcapene. One patient with mild symptoms showed spontaneous improvement. However, one patient had irreversible visual acuity reduction. The multivariate logistic regression analysis revealed that a cumulative docetaxel dose of ≥300 mg/m2 (odds ratio: 15.50, 95% confidence interval: 1.37–175.00, p = 0.027) and concomitant cyclophosphamide use (odds ratio: 13.20, 95% confidence interval: 1.13–153.00, p = 0.039) were significant risk factors associated with eye disorders. Conclusion In conclusion, it was determined that docetaxel-related eye disorders might be influenced by the cumulative dose of docetaxel and concomitant cyclophosphamide use. In addition, relatively mild symptoms improved with medication.
