Recovery of symptomatic extravasation of liposomal doxorubicin after dexrazoxane treatment

Extravasation accidents with liposomal/liposomal pegylated anthracyclines treated with dexrazoxane: an overview and outcomes

The extravasation of chemotherapeutic agents is a challenge for oncologic care teams. The management of nonliposomal (conventional) anthracyclines is well established in clinical practice guidelines, including general measures and specific antidotes, such as dexrazoxane. However, there is little scientific evidence on the management of liposomal and pegylated liposomal anthracyclines. The aim of this paper was to review the scientific literature on the extravasation of liposomal and pegylated liposomal anthracyclines and determine the clinical impact of this type of extravasation, focusing on dexrazoxane. The literature was searched using two databases: PubMed and Embase. Three searches were conducted, using liposomal anthracycline extravasation, pegylated liposomal anthracycline extravasation, and liposomal doxorubicin extravasation as keywords, respectively. Seven articles fulfilled the study eligibility criteria and included seventeen cases in humans. Extravasation occurred with three drugs: liposomal doxorubicin in nine (53%) patients, liposomal daunorubicin in four (23.5%) patients, and pegylated liposomal doxorubicin in four (23.5%) patients. General measures for extravasations were applied in all patients, but only three patients received dexrazoxane. All cases were completely resolved at 2-3 months, except for one patient, in whom dexrazoxane was not used. In animals, dexrazoxane decreased both the frequency of wounds produced by pegylated liposomal doxorubicin and their extent. The pharmacokinetic profiles of liposomal and pegylated liposomal anthracyclines differ from those of conventional anthracyclines, modifying their effectiveness and safety. General measures may be inadequate to heal areas affected by extravasation, which may require the administration of dexrazoxane. However, each case should be evaluated individually for the administration of dexrazoxane in off-label use until scientific evidence is available on its effectiveness and safety as an antidote for these formulations of anthracyclines.

Pharmacological management of anticancer agent extravasation: A single institutional guideline

Although the risk of extravasation of a chemotherapy (anticancer) medication is low, the complications associated with these events can have a significant impact on morbidity and health care costs. Institutions that administer anticancer agents should ideally have a current guideline on the proper management of the inadvertent administration of these toxic medications into tissues surrounding blood vessels. It is imperative that the health care team involved in administering drugs used to treat cancer be educated on the risk factors, preventative strategies and treatment of anticancer extravasations, as well as practice safe and proper administration techniques. Anticancer agents are generally divided into classes based on their ability to cause tissue damage. The review of current published guidelines and available literature reveals a lack of consensus on how these medications should be classified. In addition, many recently approved drugs for the treatment of cancer may lack data to support their classification and management of extravasation events. The treatment of the majority of extravasations of anticancer agents involves nonpharmacological measures, potentially in the ambulatory care setting. Antidotes are available for the extravasation of a minority of vesicant agents in order to mitigate tissue damage. Due to the limited data and lack of consensus in published guidelines, a working group was established to put forth an institutional guideline on the management of anticancer extravasations.

Complete recovery of a wide local reaction by the use of dexrazoxane 72 hours after epirubicin extravasation: case report and review of the literature

BACKGROUND

Accidental extravasation of anthracyclines might result in devastating side effects and complications, including necrosis of tissue, with impairment of neighboring structures - most of them requiring surgery. Following recent approach guidelines, intravenous administration of dexrazoxane within 6 h after the event is recommended.

CASE REPORT

We report on a 63-year-old female patient with breast cancer treated with epirubicin combination therapy. She experienced extravasation on the distal right arm at the end of the very first cycle, being initially treated with dimethylsulfoxide 99% topically. Clinical symptoms became worse. Despite the interval between the event and referral, dexrazoxane was given once daily for 3 days. She recovered completely without any sequelae.

CONCLUSION

To our knowledge, this is the first case report of a successful treatment and complete recovery by the use of dexrazoxane even 3 days after extensive epirubicin extravasation. Additionally, a review of the literature is given.

Treatment of anthracycline extravasations using dexrazoxane

Extravasation of cytotoxic agents is a true medical emergency. Dexrazoxane is the only licensed drug for the treatment of anthracycline extravasations. Dexrazoxane proved to be effective and moderately well tolerated. However, alternative approaches for the management of anthracycline extravasations are available such as topical DMSO and cooling. There appears to be general agreement about dexrazoxane usefulness when extravasations involve large volumes of anthracycline and/or central venous access device. Nevertheless, the non-invasive combination of DMSO and cooling is the most commonly described therapy, particularly in small anthracycline extravasations. Further research is still needed to establish unequivocal situations where dexrazoxane must be initiated.

Cervical extravasation of bevacizumab

Monoclonal antibodies such as bevacizumab are widely used in medical oncology, either alone or in combination with chemotherapy. No specific recommendations on the management of monoclonal antibodies extravasation exist. Incidence rates vary considerably. Estimates of 0.5-6% have been reported in the literature. Also, patient-associated and procedure-associated risk factors of extravasation are multiple, such as bolus injections or poorly implanted central venous access. We report on an 86-year-old woman with colon cancer with liver metastasis who was treated with 5-fluorouracil, folinic acid, and bevacizumab. Extravasation occurred during chemotherapy infusion because of a catheter migration of the port outside of the superior vena cava, causing cervical pain without skin modifications. Diagnosis was confirmed with the appearance of clinical right cervical tumefaction and cervicothoracic computed tomography scan indicated a perijugular hypodense collection, corresponding to the extravasation. Conservative management was proposed. The patient recovered within 3 weeks from all symptoms. Physicians should be aware that in cases of bevacizumab extravasation, a nonsurgical approach might be effective.
