Prevention of docetaxel-induced erythrodysesthesia with local hypothermia

Uncommon Adverse Effects of Commonly Used Chemotherapeutic Agents in Medical Oncology Practice: A Series of Two Cases of Hand-Foot Syndrome

Chemotherapy has an increasing potential for cure and palliation of most forms of cancer in different stages. However, its use is associated with a multitude of side effects some very common and few very rare. We present two patients of metastatic nonsmall lung cancer who had severe forms of hand-foot syndrome with two different classes of antineoplastic drugs and have to discontinue chemotherapy.

Palmar-plantar erythrodysesthesia

Objective. To provide a comprehensive review of the chemotherapy induced dermatological toxi-city, palmar-plantar erythrodysesthesia (PPE), including clinical presentation, drugs implication in causing the reaction, and approaches for management.

Data sources. A search of MEDLINE (1966-2002), IDIS (1985- 2002) and CANCERLIT (1993-2002) databases was conducted using the terms (and variations of the terms) palmar-plantar erythrodysesthesia, hand-foot syndrome, and acral erythema. Bibliographies from selected articles were also reviewed for appropriate references.

Data extraction. The retrieved literature was reviewed to include all articles pertaining to the incidence, clinical presentation, mechanism, pathology, diagnosis, treatment and prevention of PPE.

Data synthesis. PPE is a distinctive, localized cutaneous reaction to certain antineoplastic agents. A number of drugs have been implicated, including most commonly cytarabine, fluorouracil, doxorubicin, and capecitabine. There appears to be an association with administration schedules that lead to elevated peak plasma concentrations, such as in high-dose therapy, or after prolonged periods of constant exposure, as with continuous infusions, regular oral dosing, or liposomal formulations. The extent and severity of the reaction, time of onset, and duration are variable. Symptoms can occur to both hands and feet, and include dysesthesia, paresthesia, erythema, swelling, pain, blistering, ulceration, and desquamination. Cessation of the offending agent appears to be the most important step in the management of PPE. Dose modification may be necessary for subsequent cycles. As the course of PPE is self-limiting, treatment is commonly supportive and based on the type and severity of symptoms encountered. This can include analgesia, emollient or soothing creams, wound care, and cold compresses. Administration of corticosteroids has produced mixed results. Pyridoxine shows promise as both a treatment and preventative strategy, although confirmation in prospective clinical trials is needed. Advice should be provided to patients to ensure prompt recognition of toxicity and plans for prevention and amelioration of symptoms provided.

Cutaneous adverse reactions to chemotherapy with taxanes: the dermatologist's point of view

Chemotherapy with taxanes has recently become part of the treatment for many advanced neoplastic diseases, specially breast and lung cancer. Their main noncutaneous adverse reactions include neutropenia and mucositis, which eventually lead to drug discontinuation. Cutaneous adverse reactions are frequent and significantly interfere with the patient's quality of life. Treatments are poorly effective, but special recommendations may improve symptoms and prevent relapses requiring drug rechallenge.

Paracrine control of vascular innervation in health and disease

Proper vascular regulation is of paramount importance for the control of blood flow to tissues. In particular, the regulation of peripheral resistance arteries is essential for several physiological processes, including control of blood pressure, thermoregulation and increase of blood flow to central nervous system and heart under stress conditions such as hypoxia. Arterial tone is regulated by the periarterial autonomic nervous plexus, as well as by endothelium-dependent, myogenic and humoral mechanisms. Underscoring the importance of proper vascular regulation, defects in these processes can lead to diseases such as hypertension, orthostatic hypotension, Raynaud's phenomenon, defective thermoregulation, hand-foot syndrome, migraine and congestive heart failure. Here, we review the molecular mechanisms controlling the development of the periarterial nerve plexus, retrograde and localized signalling at neuro-effector junctions, the molecular and cellular mechanisms of vascular regulation and adult plasticity and maintenance of periarterial innervation. We particularly highlight a newly discovered role for vascular endothelial growth factor in the structural and functional maintenance of arterial neuro-effector junctions. Finally, we discuss how defects in neuronal vascular regulation can lead to disease.

Chemotherapy-induced palmar-plantar erythrodysesthesia syndrome: etiology and emerging therapies

Palmar-plantar erythrodysesthesia, or hand-foot syndrome (HFS), is emerging as a common, dose-dependent toxicity of many newer chemotherapy drugs. Frequently, HFS is a dose-limiting toxicity requiring discontinuation of treatment, chemotherapy dose reductions, or delays. The spectrum of symptoms of HFS can be mild, with erythema of the distal extremities, or it can be severe enough to interfere with activities of daily living. Although the exact mechanism is unknown, there are several approaches to ameliorating the symptoms of this complication. These include antiinflammatory agents, vitamin products, and peripheral vasoconstricting agents.

Palmar-plantar erythrodysesthesia secondary to docetaxel chemotherapy: a case report

Introduction

Docetaxel is a chemotherapeutic agent used alone or in combination for the management of many neoplastic conditions. Numerous side effects are well described as a consequence. Palmar-plantar erythrodysesthesia, although a relatively common side effect of some types of chemotherapy, occurs infrequently with docetaxel and is often attributed to other drug agents.

Case Presentation

We report the case of a 66-year-old Caucasian woman who received adjuvant docetaxel monotherapy for invasive breast cancer. She developed palmar-plantar erythrodysesthesia following her first cycle of treatment, which necessitated a change in management.

Conclusion

Palmar-plantar erythrodysesthesia is a relatively common side effect of cytotoxic chemotherapy, particularly with drugs such as 5-fluorouracil, capecitabine and liposomal doxorubicin. Docetaxel is commonly used both alone and in combination with a number of these agents for the management of various malignant conditions. We would like to highlight the occurrence of palmar-plantar erythrodysesthesia as a result of docetaxel monotherapy so that it can be considered as a potential cause in patients receiving combination treatment with chemotherapeutic agents better known to cause this toxicity.

Docetaxel for the post-surgery treatment of patients with node-positive breast cancer

Adjuvant chemotherapy reduces risk of relapse and cancer-related mortality in early stage breast cancer. Over the last decade, taxanes (paclitaxel and docetaxel) have been incorporated into various adjuvant trials and have demonstrated a significant benefit in the management of early stage breast cancer. Clinical trials using combinations of taxanes with targeted therapy have also shown considerable activity in breast cancer. This article reviews the pharmacology of docetaxel, a semi-synthetic taxane, and the clinical trials supporting its use in patients with node-positive breast cancer.

Chemotherapeutic agents and the skin: An update

Chemotherapeutic agents give rise to numerous well described adverse effects that may affect the skin, hair, mucous membranes, or nails. The mucocutaneous effects of longstanding agents have been extensively studied and reviewed. Over the last 2 decades, a number of new molecular entities for the treatment of cancer have been approved by the United States Food and Drug Administration (FDA). This article reviews the cutaneous toxicity patterns of these agents. It also reviews one drug that has not received FDA approval but is in use outside the United States and is important dermatologically. Particular emphasis is placed on the novel signal transduction inhibitors as well as on newer literature pertaining to previously described reactions.

LEARNING OBJECTIVES

At the completion of this learning activity, participants should able to list the newer chemotherapeutic agents that possess significant mucocutaneous side effects and describe the range of reactions that are seen with each drug. In addition, they should be able to formulate appropriate management strategies for these reactions.

Palmar-plantar erythrodysesthesia (PPE): a literature review with commentary on experience in a cancer centre

Palmar-plantar erythrodysesthesia (PPE) or hand-foot syndrome (HFS) is a relatively common side effect of cytotoxic chemotherapy. Many cytotoxic drugs have been reported to cause the condition but it is more frequently associated with 5 fluorouracil (5FU), liposomal doxorubicin and cytarabine. The oral 5FU precursor, capecitabine is frequently associated with PPE and with the recent extension of its use to adjuvant treatment, the incidence of PPE is likely to increase. The initial symptoms are dysesthesia and tingling in the palms, fingers and soles of feet and erythema, which may progress to burning pain with dryness, cracking, desquamation, ulceration and oedema. Palms of the hands are more frequently affected than soles of the feet. This condition is painful and distressing to patients and in some incidences it results in patients not being able to work or perform normal daily activities. It can also result in treatment interruptions which impact on the efficacy of the treatment regimen. Effective and appropriate patient education from a specialist nurse prior to treatment is an essential part of patient management which will facilitate early identification of the symptoms and therefore prevent treatment delays and PPE progression. This article reviews current knowledge of the condition, including classification, and discussion of the findings of a clinical audit in a cancer centre. It includes the incidence, grading, management and impact of PPE on normal daily activities.

Dermatologic toxicity of chemotherapeutic agents

Due to its high metabolic rate, skin represents one of the major target organs of chemotherapy-associated toxicity. Reactions range from common, nonspecific exanthematous eruptions to rare but distinctive cutaneous lesions that may not become apparent until a drug transitions from clinical trials to widespread oncologic use. The challenge of the physician is to recognize reaction patterns that reflect a drug reaction, identify a likely causative drug, and determine whether the reaction is a dose-limiting toxicity. This review will focus on the cutaneous side effects of the newer classes of chemotherapy drugs, including targeted monoclonal antibody therapy and small molecule inhibitors.

Vascular Toxicity of Antineoplastic Agents

Among the various deleterious effects of cancer chemotherapy, vascular toxicity is the least well recognized. This lack of recognition may be because the vasculotoxic phenomena are not unique to antineoplastic agents, can occur in patients without exposure to these agents, and the fact cancer itself may produce a hypercoagulable state. As a result, many vascular events either go unnoticed, are ignored, and/or are attributed to the underlying malignancy. Many antineoplastic therapies are associated with various vascular phenomena that range from simple phelibitis to lethal microangiopathy. Recognition of these events is important to minimize the morbidity and even prevent unnecessary deaths. Herein we review the vascular syndromes that have been reported in association with antineoplastic agents.

Acral erythrodysesthesia syndrome caused by intravenous infusion of docetaxel in breast cancer

Docetaxel-induced skin reactions include hypersensitivity, edema, skin toxicity with erythrodysesthesia syndrome, infusion site reactions, alopecia, nail onycholysis, nail pigmentation, photosensitivity, scleroderma, and others, for example, stomatitis and paresthesias. However, of all reported effects, the acral erythrodysesthesia syndrome has only rarely been described in the literature. We report on two female patients with breast cancer who on treatment with docetaxel developed acral erythrodysesthesia syndrome. It presented as bizarrely shaped, burning skin reactions at their hands and feet. Histology of skin biopsies revealed microscopic damages to the eccrine sweat glands in both patients. Skin patch testing with docetaxel was negative. None of the reports dealing with side effects of docetaxel chemotherapy has described acral erythrodysesthesia syndrome with the histologic features of syringo-squamous metaplasia and eccrine neutrophilic hidradenitis. We propose here that these characteristic histologic features are essential in the differentiation from fixed drug eruption and localized graft-versus-host disease.

Cutaneous Reactions to Chemotherapeutic Agents

The task of evaluating a cutaneous eruption in the patient receiving chemotherapy can be quite formidable. Most of the time, these patients are receiving a multitude of agents and have profound immunosuppression. These factors may alter the more common manifestations of cutaneous eruptions. This article presents some of the more common cutaneous eruptions that may occur in an oncology patient receiving chemotherapy. It is hoped we may recognize clinical patterns seen with chemotherapeutic agents in the immunosuppressed population and, by recognizing these cutaneous eruptions, we may avoid the pitfalls of discontinuing medicines that may certainly be needed or altering the treatment course in a patient.

Antineoplastic therapy-induced palmar plantar erythrodysesthesia ('hand-foot') syndrome. Incidence, recognition and management

Palmar plantar erythrodysesthesia (PPE) is a distinctive and relatively frequent toxic reaction related to some chemotherapeutic agents. Doxorubicin, cytarabine, docetaxel, and fluorouracil are the most frequently implicated agents. PPE seems to be dose dependent and both peak drug concentration and total cumulative dose determine its occurrence. PPE presents as a painful erythema, often preceded by paresthesia, located on the palms and soles in the context of treatment with chemotherapy. Histologically, PPE shows few specific findings. Mild spongiosis, scattered necrotic and dyskeratotic keratinocytes and vacuolar degeneration of the basal layer is seen. Dermal changes in most cases include dilated blood vessels, papillary edema, and a sparse superficial perivascular lymphohistiocytic infiltrate can be found in varying degrees in the epidermis. Withdrawal or dose reduction of the implicated drug usually gives rise to amelioration of the symptoms. Supportive treatments such as topical wound care, elevation, and cold compresses may help to relieve the pain. Use of systemic corticosteroids, pyridoxine (vitamin B6), blood flow reduction, and, recently, topical 99% dimethyl-sulfoxide have been used with variable outcomes. It could be of interest to consider them as preventive measures when drugs with a strong association with PPE are going to be administered.

Relationship of dose intensity to the induction of palmar-plantar erythrodysesthia by pegylated liposomal doxorubicin in dogs

The multiple dose pharmacokinetics of pegylated liposomal doxorubicin (PL-DOX), known as DOXIL (US) and CAELYX (EU), was characterized in dogs and a pharmacokinetic/pharmacodynamic model to identify a relationship between drug exposure and the probability of observing treatment-related palmar-plantar erythrodysesthesia (PPE) was developed. Twenty dogs were assigned to PL-DOX groups (2/sex/ group) that received intravenous PL-DOX doses of 0.5 mg/kg ql, 2, or 4 weeks; 1.0 mg/kg q2weeks; or 1.5 mg/kg q4weeks for 12 weeks. Blood was collected for HPLC analysis of doxorubicin concentration pre-dose and periodically up to 120 h after dosing three times during treatment. Plasma drug concentration was modeled using iterative 2-stage analysis. Dermal lesions (PPE) were scored twice weekly for six regions of each dog using a 0-6 severity scale; maximum severity was 36. PPE score data were modeled using an approach in which the % probability of PPE was related to a hypothetical effect site by a series of Hill-type functions. Pharmacokinetics were best modeled as a one-compartment open model. Vss (ml/kg), CLt (ml/hr/kg) and half-life (h) were 44.1, 1.39 and 23.1, respectively. Cmax increased linearly with dose. CLt decreased with repeated doses. 5 A two-compartment pharmacodynamic model, which correctly predicted 97% of the observed lesion severity, was developed to establish the relationship of lesion severity to dose intensity (a measure of drug exposure incorporating the effect of both dose level and dosing frequency, which can be expressed in units of mg/kg/week). The model demonstrated that maximal PPE was positively correlated with dose intensity, the major factor that affects the incidence and severity of dermal lesions. 6 The model can be used to predict acceptable dose intensities in humans utilizing body surface area conversion factors and comparative AUCs for dogs and humans. It predicts that a dose intensity of 10-12.5 mg/m2 of PL-DOX will be well tolerated in patients. The results of recent clinical studies are consistent with this prediction.
