Outcome of chemotherapy extravasation in a large patient series using a standardised management protocol.

ABSTRACT

PURPOSE: In a longitudinal observation, extravasation of antitumoural compounds and the efficacy of its structured interdisciplinary management were assessed in a routine setting. METHODS: One hundred sixty-nine patients with extravasation of cytotoxics were managed according to a prospective approach documenting the extravasated compound, localisation, duration until full symptom resolution and sequelae. Surgery was implemented in the case of failure of conservative measures. RESULTS: In 155 (91.7 %) out of 169 patients, conservative management was successful (surgical intervention, 14 patients). Extravasations of anthracyclines (N = 44), platinum compounds (N = 41), vinca alkaloids (N = 20) and taxanes (N = 19) were often associated with erythema, oedema and pain. The median period until full resolution of symptoms differed among the administered cytotoxics (anthracyclines, 55 days; taxanes and vinca alkaloids, 27 days; platinum compounds, 14 days) with statistical significance between the vesicants. Histologically, surgically resected specimens showed extensive necrotic areas with inflammatory infiltrates at the periphery of the removed lesions. CONCLUSIONS: In a routine setting, the standardised management of cytotoxic extravasations by an interdisciplinary task force resulted in a satisfactory outcome. When surgical intervention was indicated, complete remission of the lesions within a median of 14 days reduced the delay in the administration of further chemotherapy to a minimum. The proposed approach is therefore considered as suitable to manage extravasations in cancer chemotherapy in a large number of subjects and to ensure patient adherence to cytotoxic treatment.
