Combined management in the treatment of epidoxorubicin extravasation. A case report.

Inadvertent extravasation during intravenous antitumor therapy is not an unusual complication and can cause damage ranging from minor erythema to severe local necrosis. The appropriate management of these iatrogenic accidents as a part of supportive care in oncology has been addressed by several experimental studies, but there has been little clinical study and no conclusive evidence on the best therapeutic strategies to adopt. The case reported here of a patient suffering from severe soft-tissue injury caused by extravasation of epidoxorubicin demonstrates the usefulness of a combined management (medical, surgical and rehabilitative) in the appropriate care of extravasation.

Topical dimethylsulfoxide for the prevention of soft tissue injury after extravasation of vesicant cytotoxic drugs: a prospective clinical study.

PURPOSE: To evaluate the activity and tolerability of dimethylsulfoxide (DMSO) in the prevention of soft tissue toxicity after extravasation of cytotoxic drugs. PATIENTS AND METHODS: From June 1991 to December 1994, all patients who had an extravasation during intravenous (IV) infusion of cytotoxic drugs in our institution were considered for an open, prospective study of preventive treatment with 99% DMSO, applied topically on the extravasation site every 8 hours for 7 days. Intermittent local cooling (for 1 hour three times daily) on the first 3 days was also used. RESULTS: One hundred forty-four patients with extravasations of doxorubicin (n = 11), epirubicin (n = 46), mitomycin (n = 5), mitoxantrone (n = 13), cisplatin (n = 44), carboplatin (n = 6), ifosfamide (n = 14), and fluorouracil (n = 5) entered the study; 127 were assessable. Only one patient suffered an ulceration. The treatment was well tolerated, with mild local burning and a characteristic breath odor being the only side effects of DMSO application, even in cases in which treatment continued for up to 6 weeks to obtain remission of the symptoms of extravasation. CONCLUSION: Topical DMSO is an effective and safe antidote that may be used with local cooling after extravasations of vesicant drugs other than those drugs for which standard interventions are defined.

[Sulodexide in the prevention of post-mastectomy lymphedema].

Post-mastectomy lymphedema of the upper limb, that can be noticed by 10 to 20 percent of patients with breast cancer, is usually related to some risk factors: use of radiotherapy on the axilla, obesity, venous outflow obstruction, delayed wound healing or infection. The most important contributing factor to postsurgical edema is the development of lymphangitis in the upper limb. Although literature contains numerous accounts on the use of pharmacological agents for the treatment of postmastectomy lymphedema, the results are not satisfactory in term of clinical response and side effects. In the present study we investigate tolerability and feasibility of the use of suledexide in patients, submitted to mastectomy for breast cancer, with an initial lymphedema of the limb omolateral to surgery or other risk factors for the development of a clinical remarkable lymphedema. Our results show that sulodexide is a very satisfactory therapy in term of lack of side effects and good compliance.

Hyaluronidase as an antidote to extravasation of Vinca alkaloids: clinical results.

Skin necrosis is a recognized potential consequence of an inadvertent extravasation of Vinca alkaloids in the surrounding tissues during i.v. administration. Experimental studies suggest that hyaluronidase, an enzyme that degrades hyaluronic acid and improves the absorption of locally injected drugs, can reduce the risk of progressing to skin necrosis. On this basis, we used this enzyme as a local treatment after extravasations of Vinca alkaloids in seven patients. No patient suffered from subsequent skin necrosis. To the best of our knowledge, this is the first clinical report confirming the positive findings of experimental studies on the effectiveness of this antidote.

Management of acute radiodermatitis. Pharmacological or nonpharmacological remedies?

The medical and nursing literature suggests a wide variety of pharmacological and nonpharmacological approaches to treatment of acute radiation skin damages (erythema, dry and moist desquamation, ulceration), but no specific and standardized therapy. The incidence of radiodermatitis has decreased with mega-voltage instruments, but it can nevertheless influence the therapeutic program and impair quality of life of patients. A study has been conducted to evaluate the tolerability and effectiveness of a nonpharmacological remedy, a mixture of hydrophobic (stearic acid) and hydrophilic (propylene glycol, glycerol, and polyunsaturated alcohols) components in a foam emulsion for the treatment of acute skin injuries following radiotherapy. Thirty-eight of 42 initial patients were evaluable: we observed a complete response in 22 (57.9%), improvement in 14 (36.8%), and failure in only two (5.3%).
