Taxane-induced nail changes: incidence, clinical presentation and outcome

Nail toxicities induced by systemic anticancer treatments

Patients treated with systemic anticancer drugs often show changes to their nails, which are usually well tolerated and disappear on cessation of treatment. However, some nail toxicities can cause pain and functional impairment and thus substantially affect a patient's quality of life, especially if they are given taxanes or EGFR inhibitors. These nail toxicities can affect both the nail plate and bed, and might present as melanonychia, leukonychia, onycholysis, onychomadesis, Beau's lines, or onychorrhexis, as frequently noted with conventional chemotherapies. Additionally, the periungual area (perionychium) of the nail might be affected by paronychia or pyogenic granuloma, especially in patients treated with drugs targeting EGFR or MEK. We review the nail changes induced by conventional chemotherapies and those associated with the use of targeted anticancer drugs and discuss preventive or curative options.

Supportive cryotherapy: a review from head to toe

CONTEXT

Conventional chemotherapy leads to multiple adverse mucocutaneous complications such as oral mucositis, alopecia, ocular toxicity, and onycholysis. Limited pharmacologic interventions are available for preventing these clinical problems.

OBJECTIVES

This study aimed to critically review the role of cryotherapy (regional hypothermia) for alleviating these adverse symptoms.

METHODS

A narrative review was performed, with an emphasis on randomized controlled trials. A comprehensive search using PubMed, Ovid, Embase, and MEDLINE(®) was completed. References of all cited articles also were reviewed. Data from the review were composed of articles published between 1970 and May 2013.

RESULTS

Available evidence suggests that regional hypothermia decreases the burden of chemotherapy-related oral mucositis, alopecia, ocular toxicity, and onycholysis. The major limitations of studies include the absence of blinded control groups and variable clinical end points.

CONCLUSION

Regional hypothermia decreases the burden of these four chemotherapy-induced complications and is well tolerated. More research is needed to determine what subgroups of cancer patients are most likely to respond to different types of regional hypothermia, the ideal duration of cooling needed, and further improve the ease of use of the cooling devices.

Nail abnormalities associated with systemic pathologies

Nail abnormalities can arise in conjunction with or as a result of systematic pathologies. These pathologies include single-organ diseases, multisystemic diseases, and drug-induced insults. Clinical signs associated with these conditions include dyschromias, vascular alterations, periungual tissue changes, textural dystrophies, contour alterations, and growth-rate alterations. The associated systemic pathologies may affect any part of the nail apparatus, including the nail matrix, the nail plate, the nail bed, the underlying vasculature, and the periungual tissues. The anatomical location and extent of damage determine the clinically manifested anomaly.

Chemotherapy-induced hand-foot syndrome and nail changes: a review of clinical presentation, etiology, pathogenesis, and management

Chemotherapy-induced hand-foot syndrome and nail changes are common complications of many classic chemotherapeutic agents and the newer molecular targeted therapies. They significantly impact patient quality of life, and frequently necessitate chemotherapy dose intensity modification or reduction. We aim to describe the epidemiology, pathogenesis, clinical presentation, and current evidence-based treatment options for these entities.

Degree of freezing does not affect efficacy of frozen gloves for prevention of docetaxel-induced nail toxicity in breast cancer patients

PURPOSE

Frozen gloves (FG) are effective in preventing docetaxel-induced nail toxicity (DNT), but uncomfortable. The preventive effect of FG for DNT was compared using a standard (-25 to -30°C) or more comfortable (-10 to -20°C) preparation.

METHODS

Breast cancer patients receiving docetaxel were eligible. Each patient wore an FG (prepared at -10 to -20°C for 90 min) for 60 min without replacement on the right hand. The left hand was protected by standard methods (FG prepared at -25 to -30°C overnight and worn for 90 min with replacement at 45 min). The primary endpoint was DNT occurrence at 5 months. Secondary endpoints included docetaxel exposure [cumulative dose and area under the blood concentration time curve (AUC)] until DNT occurrence and discomfort from FG. The pharmacokinetics of docetaxel was assessed.

RESULTS

From 23 patients enrolled between December 2006 and June 2010, seven who received docetaxel for less than 5 months were excluded from evaluation. The median accumulated docetaxel dose was 700 mg/m(2) (340-1430 mg/m(2)). Within 5 months of FG use, none developed protocol-defined DNT in either hand. Two patients (13%) developed DNT at 7.2 and 7.3 months, respectively, both at -10 to -20°C. In the control hand (-25 to -30°C), discomfort occurred in 92% of the cycles, compared to 15% in the experimental hand (-10 to -20°C). Five patients (22%) experienced pain at -25 to -30°C, but none did at -10 to -20°C. The degree of docetaxel exposure was not related to DNT occurrence in our study.

CONCLUSION

A convenient preparation of FG at -10 to -20°C is almost as effective as a standard preparation at -25 to -30°C, with significantly less discomfort.

Grading dermatologic adverse events of cancer treatments: the Common Terminology Criteria for Adverse Events Version 4.0

Dermatologic adverse events to cancer therapies have become more prevalent and may to lead to dose modifications or discontinuation of life-saving or prolonging treatments. This has resulted in a new collaboration between oncologists and dermatologists, which requires accurate cataloging and grading of side effects. The Common Terminology Criteria for Adverse Events Version 4.0 is a descriptive terminology and grading system that can be used for uniform reporting of adverse events. A proper understanding of this standardized classification system is essential for dermatologists to properly communicate with all physicians caring for patients with cancer.

Cabazitaxel Side Effects: Prevention and Management

The publication of phase III data on cabazitaxel in the management of metastatic castrate-resistant prostate cancer in men previously treated with docetaxel demonstrated, for the first time, that a survival benefit can be achieved in this patient group. Optimal use of cabazitaxel will depend on appropriate patient selection and on effective management of the side effects, which have been shown to be predictable and preventable/treatable using interventions that are already familiar to chemotherapy clinics.

Periungual and subungual pyogenic granuloma

BACKGROUND

Nail pyogenic granuloma (PG) is common, often seen as an urgent case, given the recent onset as a bleeding nodule. Nail PGs are due to different causes that act through different pathogenetic mechanisms and may be treated in several ways. Both causes and treatments of nail PG have never been classified.

OBJECTIVES

To classify nail PG according to the pathogenesis, describe the clinical and pathological features and provide guidelines for a correct diagnosis and treatment.

METHODS

A retrospective, observational study was performed reviewing epidemiological and clinical features of 58 cases of PG seen at our Departments in the last 5 years. A review of the literature was also carried out, using PubMed database and dermatological textbooks.

RESULTS

Nail PG is usually due to the following causes: drugs, local trauma and peripheral nerve injury. Histopathology shows similar features in every type of PG, irrespective of cause and location.

CONCLUSIONS

The localization of nail PG, the number of digits involved and clinical history help to identify the cause. When PG is single, especially if it involves the nail bed, histological examination is necessary to rule out malignant melanoma. Treatment must be chosen according to the underlying cause.

Nail Toxicity Induced by Cancer Chemotherapy

Purpose. To provide a comprehensive literature review of chemotherapy-induced nail toxicity, including clinical presentation, implicated drugs and approaches for prevention and management.

Data sources. A search of MEDLINE and EMBASE (1966—2008) databases was conducted using the terms (and variations of the terms) antineoplastic agents, nails, nail toxicity, onycholysis, and paronychia. Bibliographies from selected articles were reviewed for appropriate references.

Data extraction. The retrieved literature was reviewed to include all articles relevant to the clinical presentation, diagnosis, incidence, prevention, and treatment of chemotherapy-induced nail toxicity.

Data synthesis. Nail toxicity is a relatively uncommon adverse effect linked to a number of chemotherapeutic agents. Clinical presentation varies, depending on which nail structure is affected and the severity of the insult. Nail changes may involve all or some nails. Toxicity may be asymptomatic and limited to cosmetic concerns, however, more severe effects, involving pain and discomfort can occur. Taxanes and anthracyclines are the antineoplastic drug groups most commonly implicated. It is suggested that the administration schedule may influence the incidence of nail abnormalities, for example reported cases linked to the weekly administration of paclitaxel.

Before instituting chemotherapy, patients should be educated regarding potential nail toxicities and strategies for prevention implemented. Management includes appropriate nail cutting, avoiding potential irritants, topical, or oral antimicrobials, and possibly cessation or dose reduction of the offending agent. Cryotherapy, through the application of frozen gloves or socks, has been beneficial in reducing docetaxel-induced nail toxicity and may be effective for other drugs.

Matched case-control phase 2 study to evaluate the use of a frozen sock to prevent docetaxel-induced onycholysis and cutaneous toxicity of the foot

BACKGROUND

Onycholysis occurs in approximately 30% of patients treated with docetaxel. The efficacy and safety of an Elasto-Gel frozen sock (FS) was investigated for the prevention of docetaxel-induced nail and skin toxicity of the feet.

METHODS

Patients receiving docetaxel at a dose of 70 to 100 mg/m(2) every 3 weeks were eligible for this matched case-control study. Each patient wore an FS for 90 minutes on the right foot. The unprotected left foot acted as control. Nail and skin toxicities were assessed using National Cancer Institute Common Toxicity Criteria (version 3) and compared using a 2-sample Wilcoxon matched-pairs rank test adjusted for tied values.

RESULTS

Fifty consecutive patients were included between April 2005 and January 2007. Nail toxicity was significantly lower in the FS-protected foot compared with the control foot (grade 0: 100% versus 79%; and grade 1 and 2: 0% versus 21%, respectively) (P= .002). Skin toxicity was grade 0: 98% versus 94%; and grade 1 and 2: 2% versus 6% in the FS-protected and the control feet, respectively. The median times until toxicity occurrence were not found to differ significantly between the groups. One patient experienced discomfort because of cold intolerance.

CONCLUSIONS

Cold therapy using FS significantly reduced the incidence of docetaxel-induced foot nail toxicity, as previously demonstrated using frozen gloves for the hands.

Toxicity of dose-dense docetaxel followed by doxorubicin with cyclophosphamide as adjuvant therapy for breast cancer in a phase II study

PURPOSE

In order to evaluate the feasibility of dose-dense docetaxel followed by dose-dense AC (doxorubicin/cyclophosphamide) as adjuvant chemotherapy for operable breast cancer, we conducted a phase II study.

PATIENTS AND METHODS

In cohort 1, 28 patients received docetaxel 100 mg/m2 followed by doxorubicin 60 mg/m2 with cyclophosphamide 600 mg/m2, each every 2 weeks for 4 weeks (total of 8 cycles). Enrollment was discontinued because of stopping criteria based on significant toxicity (grade 4 hematologic toxicity or grade >or= 3 nonhematologic toxicity). In cohort 2, the docetaxel dose was reduced to 75 mg/m2; enrollment was discontinued after 18 patients.

RESULTS

Significant toxicity occurred in 79% and 72% of patients in cohorts 1 and 2, respectively, resulting in treatment delays in 50% and 17% of patients, respectively. The most common grade 4 hematologic toxicity was neutropenia, which occurred in 7% and 42% of cohort 1 patients during docetaxel and AC, respectively, and in none and 19% of cohort 2 patients, respectively. The most common grade >or= 3 nonhematologic toxicity was palmar-plantar erythrodysesthesia, which occurred in 25% and none of cohort 1 patients during docetaxel and AC, respectively. With docetaxel 75 mg/m2 and patient education encouraging routine use of topical strategies, grade 3 palmar-plantar erythrodysesthesia occurred in only 11% of cohort 2 patients. Grade 2 nail changes were also debilitating and occurred in 33% of cohort 1 patients during AC.

CONCLUSION

These phase II findings suggest that dose-dense docetaxel 100 mg/m2 followed by AC is not feasible and, until more studies are conducted, should be restricted to clinical studies.

Paclitaxel-induced cutaneous lupus erythematosus in patients with serum anti-SSA/Ro antibody

Two women (aged 46 and 56 years) developed annular erythema on their sun-exposed skin, including their forearms and faces, after biweekly i.v. administration of paclitaxel for 3-4 months to treat breast cancer. Both cases showed interface changes of basal keratinocytes and high titers of serum anti-SSA/Ro antibody. The diagnoses of paclitaxel-induced cutaneous lupus erythematosus (LE) were made because the skin eruptions cleared rapidly within 3 weeks after the paclitaxel treatment was discontinued. Paclitaxel is proposed to be a causative agent that can provoke cutaneous LE.

Acute felon as a complication of systemic paclitaxel therapy: case report and review of the literature

Breast cancer now affects 1 in 8 American women and the taxane agent paclitaxel (Taxol Bristol-Myers Squibb) is a major tool in the treatment of many such patients. Hand surgeons are therefore likely to encounter upper extremity complications related to the use of taxane therapy. We present an unusual case of a felon developing in a breast cancer patient on paclitaxel therapy with no antecedent history of trauma. Whereas onycholysis and subungual hemorrhage are reported complications of taxane therapy (Fig. 1), an acute felon with or without associated paronychia is an unusual and more aggressive manifestation of this drug-related nail dystrophy.

Drug reactions affecting the nail unit: diagnosis and management

Several drugs may be responsible for the development of nail abnormalities, but only a few classes are consistently associated with nail symptoms. Drug-induced nail abnormalities result from toxicity to the matrix, the nail bed, the periungual tissues, or the digit blood vessels. Pharmacologic agents that most frequently produce nail abnormalities include retinoids, indinavir, and cancer chemotherapeutic agents.

Nail Toxicity after Treatment with Docetaxel: A Prospective Analysis in Patients with Advanced Non-small Cell Lung Cancer

OBJECTIVE

Nail toxicity is one of the most frequent non-hematologic toxicities of docetaxel and often deteriorates patients' quality of life, leading to treatment discontinuation. To define the incidence of nail change as well as its association with specific risk factors, we prospectively investigated data of 84 consecutive patients with advanced non-small cell lung cancer who received first-line docetaxel/cisplatin combination chemotherapy.

METHODS

Chemotherapy-naïve patients were treated with docetaxel, either 3-weekly or weekly, in combination with cisplatin. All patients received adequate premedications including corticosteroids, antiemetics and intravenous hydration. Toxicity was evaluated using National Cancer Institute (NCI) CTCAE version 3.

RESULTS

Twenty-two patients (26%) developed nail changes, including nine (11%) with grade 3. Nine patients who developed grade 3 nail changes (seven of whom received weekly docetaxel) were not able to complete planned chemotherapy despite topical and/or oral antibiotic treatment. Most occurrences of nail changes were diagnosed in patients who were treated with weekly schedule (P = 0.02). The number of chemotherapy cycles and cumulative docetaxel doses were strongly associated with the development of nail changes. The cumulative hazard of developing nail changes increased above 10% after 2.8 months up to 40% at 6 months. A multivariate analysis of factors associated with the development of nail changes identified the following to have independent adverse significance: weekly docetaxel administration (odds ratio, 0.084; 95% CI, 0.014-0.510; P = 0.01) and the number of chemotherapy cycles given (odds ratio, 0.232; 95% CI, 0.067-0.805; P = 0.02).

CONCLUSION

Nail changes occur with more frequent and prolonged use of docetaxel.

Docetaxel-induced onycholysis: the role of subungual hemorrhage and suppuration

Nail changes are common side effects of taxane chemotherapeutic agents. Docetaxel (Taxotere) is known to cause a great incidence of nail change. Various types of nail changes have previously been reported as a result of treatment with taxanes. We describe 2 cases of severe nail changes induced by docetaxel. The patients had previously been diagnosed with breast cancer and advanced gastric cancer, respectively. During the course of treatment with docetaxel, nail changes became apparent in both patients. Initially, they complained of nail bed purpura. Subungual hematomas with hemopurulent discharge were later observed in several fingers. Drainage of the hemopurulent material occurred spontaneously in our cases, leading to onycholysis. Following drainage, the pain in the nail with subungual hemoprulent material was relieved immediately and spontaneous healing of the patients' nails was noticed after few months. Subungual hemorrhage and suppuration therefore are considered causes of onycholysis and the pain in these patients. Although systemic or topical antibiotics were not used to treat these patients, antibiotics may be also worthwhile to hasten the drainage of the subungual hematomas and suppuration in patients for quick relief of pain.

Nail changes due to docetaxel--a neglected side effect and nuisance for the patient

GOALS OF WORK

The objective of this study is to estimate the frequency and severity of nail changes due to treatment with the cytotoxic drug docetaxel and, secondly, to estimate how the nail changes effects the patients cosmetically and functionally in their daily activities. Finally, we want to clarify whether fungal infection could contribute in causing the nail changes.

MATERIALS AND METHODS

Fifty-five patients with metastatic breast cancer in treatment with the cytotoxic drug docetaxel participated in the study. They filled out two questionnaires about their experience with possible nail changes. The frequency of fungal infection was examined. At each of the two visits, information about the number of treatment cycles, dose of docetaxel the patient received, frequency of lymph oedema, previous treatment with chemotherapy and the reason of discontinuance of treatment, if relevant, were registered. Finally, photos were taken to document the nail changes in hands and feet.

MAIN RESULTS

Fifty-eight percent had some degree of nail changes and an increase to 88.5% was seen after three additional cycles. A large proportion of the patients experienced the nail changes as a cosmetic nuisance, and more than 32% had functional problems.

CONCLUSION

Nail changes occur more frequently than previous studies have shown. Furthermore, our study indicates that the nail changes are affecting a large proportion of the patients, both cosmetically and functionally, which may lead to a decrease in their quality of life. No significant association was found according to the possible relation between nail changes and fungal infection.

Nail changes associated with chemotherapy in children

BACKGROUND

Large series of chemotherapy-induced nail changes in children have rarely been reported in the literature.

OBJECTIVE

To study the pattern and onset of nail changes in cancer children receiving various chemotherapy regimens.

METHODS

A cross-sectional study was performed on 30 paediatric patients (aged 1-17, mean 8.3 years), including 11 with acute lymphoblastic leukaemia, five with acute myeloid leukaemia, and others.

RESULTS

Nail changes developed in 10 children during chemotherapy, five of whom had Muehrcke's lines, three Beau's lines, one Mees' lines and another had trachyonychia. There appeared to be no correlation between the pattern of nail alteration and the underlying cancer types or stages, or the regimens of chemotherapy.

CONCLUSION

One third of the children with cancers developed nail changes associated with chemotherapy. Among them, Muehrcke's lines were the most common manifestation, which were unrelated to hypoalbuminaemia in our series.

Chemotherapy and Cutaneous Toxicities: Implications for Oncology Nurses

OBJECTIVE

To review common cutaneous effects and dermatologic or cutaneous toxicities related to the administration of chemotherapy. These range from mostly cosmetic, such as hyperpigmentation or alopecia, to dose-limiting toxicities such as palmar-plantar erythrodysesthesia or hand-foot syndrome.

DATA SOURCES

Current research, published literature, and internet resources.

CONCLUSION

Assessment and grading of associated toxicities of therapy is an integral part of caring for this patient population. Early intervention may reduce toxicities associated with therapies for this patient population

IMPLICATIONS FOR NURSING PRACTICE

As more patients receive chemotherapy, dermatologic effects are becoming more common. Oncology nurses must be skilled in managing these side effects.

Drug-induced Nail Diseases

Although many nail disorders have been associated with drug intake, most reports are anecdotal. Most nail changes caused by drugs are the outcome of acute toxicity to the nail epithelia; nail symptoms depend on which nail structure is damaged. The most com-mon symptoms include Beau's lines/onychomadesis, melanonychia, onycholysis, and periungual pyogenic granulomas. Drug-induced nail abnormalities are usually transitory and disappear with drug withdrawal, but sometimes persist over time. This article reviews drugs that have been consistently associated with nail abnormalities.

Multicenter study of a frozen glove to prevent docetaxel-induced onycholysis and cutaneous toxicity of the hand

PURPOSE

Onycholysis and skin toxicity occur in approximately 30% of patients treated with docetaxel. We investigated the efficacy and safety of an Elasto-Gel (84400 APT Cedex, Akromed, France) frozen glove (FG) for the prevention of docetaxel-induced onycholysis and skin toxicity.

PATIENTS AND METHODS

Patients receiving docetaxel 75 mg/m2 alone or in combination chemotherapy were eligible for this case-control study. Each patient wore an FG for a total of 90 minutes on the right hand. The left hand was not protected and acted as the control. Onycholysis and skin toxicity were assessed at each cycle by National Cancer Institute Common Toxicity Criteria and documented by photography. Wilcoxon matched-pairs rank test was used.

RESULTS

Between August 2002 and September 2003, 45 patients were evaluated. Onycholysis and skin toxicity were significantly lower in the FG-protected hand compared with the control hand (P = .0001). Onycholysis was grade (G) 0 in 89% v 49% and G1 to 2 in 11% v 51% for the FG-protected hand and the control hand, respectively. Skin toxicity was G0 in 73% v 41% and G1 to 2 in 27% v 59% for the FG-protected and the control hand, respectively. Median time to nail and skin toxicity occurrence was not significantly different between the FG-protected and the control hand, respectively (106 v 58 days for nail toxicity; 57 v 58 days for skin toxicity). Five patients (11%) experienced discomfort due to cold intolerance.

CONCLUSION

FG significantly reduces the nail and skin toxicity associated with docetaxel and provides a new tool in supportive care management to improve a patient's quality of life.

Phase I and pharmacokinetic study of docetaxel combined with melphalan and carboplatin, with autologous hematopoietic progenitor cell support, in patients with advanced refractory malignancies

The purpose of this study was to define the maximal tolerated dose (MTD), extramedullary toxicities, and pharmacokinetics of docetaxel combined with high-dose melphalan and carboplatin with autologous hematopoietic progenitor cell support. Fifty-nine patients with advanced refractory malignancy (32 breast cancer, 10 non-Hodgkin lymphoma, 6 germ cell tumors, 4 Hodgkin disease, 4 ovarian cancer, 2 sarcoma, and 1 unknown primary adenocarcinoma) with a median of 3 prior chemotherapy regimens and a median of 3 organs involved were enrolled. Treatment included docetaxel (150-550 mg/m2 infused over 2 hours on day -6), melphalan (150-165 mg/m2 infused over 15 minutes from day -5 to -3), and carboplatin (1000-1300 mg/m2 as a 72-hour continuous infusion from day -5). Five patients died from direct regimen-related organ toxicity (2 capillary leak syndrome, 2 enterocolitis, and 1 hepatic toxicity), and 1 additional patient died from pulmonary aspergillosis. The docetaxel MTD was defined as 400 mg/m 2 , combined with melphalan (150 mg/m2 ) and carboplatin (1000 mg/m2 ). The MTD cohort was expanded to enroll a total of 26 patients, 1 of whom died from toxic enterocolitis. The remaining 25 patients presented the following extramedullary toxicity profile, which was manageable and largely reversible: stomatitis, myoarthralgias, peripheral neuropathy, gastrointestinal and cutaneous toxicities, and syndrome of inappropriate antidiuretic hormone secretion. Docetaxel exhibited linear pharmacokinetics in the dose range tested (150-550 mg/m2 ). Pharmacodynamic correlations were noted between the docetaxel area under the curve and peripheral neuropathy or stomatitis. The response rate among 38 patients with measurable disease was 95%, with 47% complete responses. At a median follow-up of 26 months (range, 7-72 months), the 3-year event-free survival and overall survival were 26% and 36%, respectively. In conclusion, a 4-fold dose escalation of docetaxel, combined with melphalan and carboplatin, is feasible with autologous hematopoietic progenitor cell support. The notable activity of this regimen in treatment-refractory patients warrants its further evaluation.

Drug-induced nail abnormalities

A large number of drugs may be responsible for the development of nail changes, including cancer chemotherapeutic agents and retinoids, however, only a few classes of drugs are consistently associated with nail symptoms. Drug-induced nail abnormalities result from toxicity to the matrix, the nail bed, the periungual tissues or the digit blood vessels. The most common symptoms include Beau's lines, onychomadesis, melanonychia, onycholysis and periungual pyogenic granulomas. Drug-induced nail changes usually involve several or all of the nails. In most cases, nail abnormalities are asymptomatic, but can sometimes cause pain and impair manual activities.

Weekly docetaxel is safe and effective in the treatment of advanced-stage acquired immunodeficiency syndrome-related Kaposi sarcoma

BACKGROUND

Intravenous paclitaxel, 100 mg/m(2), given over 3 hours every 2 weeks is associated with a response rate of 59% in patients with recurrent or refractory acquired immunodeficiency syndrome (AIDS)-related Kaposi sarcoma (KS). However, this regimen is associated with significant myelosuppression, and the inconvenience of a 3-hour infusion. Moreover, no effective therapies have been defined for use after treatment failure with this agent. A Phase II trial was conducted with weekly docetaxel in patients with advanced-stage KS to assess safety and antitumor activity.

METHODS

Docetaxel was administered at a dose of 25 mg/m(2) intravenously over 15-30 minutes weekly for 8 weeks. Thereafter, if the patient experienced stable disease or better response, treatment doses were given every other week until complete disease remission, disease progression, or unacceptable toxicity occurred.

RESULTS

Twelve patients were accrued-9 had > 25 mucocutaneous lesions, 1 had lymphedema, and 2 had visceral involvement. Ten patients (83%) had previous systemic chemotherapy, including 4 who received previous paclitaxel. Treatment was well tolerated, with no Grade 4 toxicity of any type. Grade 3 neutropenia occurred in 33% of patients but no patient had neutropenic fever. Five patients (42%) achieved a partial response, including 1 who had previously failed to respond to paclitaxel. The median time to disease progression was 26 months (range, 5-53 months). With a median follow-up period of 45 months, the median survival point had not been reached.

CONCLUSIONS

Weekly docetaxel is safe, with reasonable antitumor activity in patients with advanced-stage, recurrent, or refractory AIDS-related KS.

Nail changes during docetaxel containing combination chemotherapy

Nail toxicity following systemic chemotherapy is common. Onychopathy during the period of neutropenia following chemotherapy may cause subungual abscesses and serious infection. Despite taxoid-related toxicity being increasingly reported since 2000, there are still phase II systemic chemotherapy studies using taxoid that have never mentioned nail changes. Recently, new criteria for the evaluation of nail toxicity have been suggested. The present report is the first of its kind, in Korea, to describe a case of docetaxel-associated onychopathy, which improved following a reduction in the docetaxel dose.
