454P - Predictors of severity and comparison of CTCAE V3.0 vs V4.3 in assessing chemotherapy induced extravasation injuries

Abstract

BackgroundExtravasation is an important Adverse Event in chemotherapy, which is evaluated using CTCAE (Common Terminology Criteria for Adverse Events) grading scale. This study focuses on predicting risk factors and comparing CTCAE v3.0 and 4.3 in assessing chemotherapy-induced extravasation. MethodsAn observational study was conducted in medical oncology wards of a tertiary care hospital among adult patients receiving parenteral chemotherapy. European society of medical oncology – European oncology nursing society (ESMO-EONS) guidelines was used to classify chemotherapeutic agents. Significant risk factors were determined using binary logistic analysis. Spearman’s rank correlation coefficient and Wilcoxon’s sign rank test was applied to evaluate the difference between CTCAE v3.0 and v4.3. ResultsA total of 46 patients were enrolled in the study. According to CTCAE v4.3, amongst the 46 patients who experienced extravasation 30 presented with Grade II and the rest 16 with Grade III severity. Patients aged above 60 years showed significance (OR: 2.236, p = 0.007), and females were prone to severe extravasation injury (OR: 2.713, p = 0.010). Ambulation was found to be a major risk factor (OR: 4.66, p = 0.001). Patients with comorbidities had higher chances of getting severe extravasation (OR: 3.009, p = 0.029) and irritants were found to be predominant in worsening it (OR: 2.24, p = 0.007). The Spearman’s rank correlation coefficient established a good association in EV grades between both versions of CTCAE (rho=0.877, p = 0.000). Wilcoxon’s Rank test revealed a significant difference between the two. (p = 0.0003). ConclusionsThe severity of EV depends on early identification of symptoms, patient related factors and nature of drug. This information is pivotal to work towards a scenario of better-prevented and managed events of EV. The updated versions of CTCAE (v4.3 and v5) are better fit to use for accurate scoring of severity. Legal entity responsible for the studyAll Authors. FundingHas not received any funding.
