Taxane-induced scleroderma: report of two cases / Esclerodermia inducida por taxanos: informe de dos casos

ABSTRACT Taxanes are a class of chemotherapeutic agents with common associated dermatologic adverse events, such as skin hyperpigmentation, hand-foot skin syndrome, paronychia and onycholysis. Taxane-induced scleroderma is rare. Few cases with skin findings resembling systemic sclerosis, have been reported after the administration of these agents. We report two cases with stage IV breast cancer, aged 66 and 71 years, who developed sclerodermic skin lesions in their extremities after starting treatment with placlitaxel and nabplaclitaxel respectively.

Los taxanos son agentes quimioterapéuticos cuyo uso se asocia a problemas dermatológicos tales como hiperpigmentación, síndrome manos-pies, paroniquia y onicolisis. La esclerodermia inducida por taxanos es rara, con pocos casos informados en la literatura. Informamos los casos de dos pacientes con cáncer de mama en estado IV, de 66 y 71 años, que desarrollaron lesiones esclerodérmicas en las extremidades después de ser tratadas con placlitaxel y nabplaclitaxel, respectivamente.

Assessing taxane-associated adverse events using the FDA adverse event reporting system database / 中华医学杂志(英文版)

BACKGROUND@#Taxanes are an essential class of antineoplastic agents used to treat various cancers and are a fundamental cause of hypersensitivity reactions. In addition, other adverse events, such as bone marrow toxicity and peripheral neuropathy, can lead to chemotherapy discontinuation. This study aimed to evaluate the safety of taxanes in the real world.@*METHODS@#Taxane-associated adverse events were identified by the Medical Dictionary for Regulatory Activities Preferred Terms and analyzed and compared by mining the US Food and Drug Administration Adverse Event Reporting System pharmacovigilance database from January 2004 to December 2019. Reported adverse events, such as hypersensitivity reaction, bone marrow toxicity, and peripheral neuropathy, were analyzed with the following signal detection algorithms: reporting odds ratio (ROR), proportional reporting ratio (PRR), multi-item gamma Poisson shrinker (MGPS), Bayesian confidence propagation neural network (BCPNN), and logistic regression methods. Adverse outcome events and death outcome rates were compared between different taxane groups using Pearson's χ2 test, whereas significance was determined at P < 0.05 with a 95% confidence interval (CI).@*RESULTS@#A total of 966 reports of hypersensitivity reactions, 1109 reports of bone marrow toxicity, and 1374 reports of peripheral neuropathy were analyzed. Compared with paclitaxel and docetaxel, bone marrow toxicity following the use of nab-paclitaxel had the highest ROR of 6.45 (95% two-sided CI, 6.05-6.88), PRR of 5.66, (χ2 = 4342.98), information component of 2.50 (95% one-sided CI = 2.34), and empirical Bayes geometric mean of 5.64 (95% one-sided CI = 5.34). Peripheral neuropathy following the use of nab-paclitaxel showed a higher ROR of 12.78 (95% two-sided CI, 11.55-14.14), PRR of 12.16 (χ2 = 4060.88), information component of 3.59 (95% one-sided CI = 3.25), and empirical Bayes geometric mean of 12.07 (95% one-sided CI = 11.09).@*CONCLUSIONS@#The results showed that bone marrow toxicity and peripheral neuropathy were the major adverse events induced by taxanes. Nab-paclitaxel exhibited the highest potential for taxane-associated adverse events. Further research in the future is warranted to explain taxane-associated adverse effects in real-world circumstances.

Identificação, Prevenção e Tratamento da Síndrome Mão-Pé Induzida por Quimioterapia: Revisão Sistemática / Identification, Prevention and Treatment of Hand-Foot Syndrome Induced by Chemotherapy: Systematic Review / Identificación, Prevención y Tratamiento de la Enfermedad Mental por Quimioterapia: Revisión Sistemática

Introdução: A síndrome mão-pé é uma reação adversa experimentada por vários pacientes em tratamento para o câncer e fator preditor de morbidade e mortalidade. Objetivo: Avaliar as evidências científicas relacionadas à identificação, prevenção e tratamento da síndrome mão-pé induzida por agentes quimioterápicos, identificar os principais sinais e sintomas que possibilitam o reconhecimento da síndrome e, ainda, discutir a ocorrência de onicomicoses no contexto da síndrome mão-pé. Método: Trata-se de uma revisão sistemática na MEDLINE/PubMed, Biblioteca Virtual da Saúde e Scopus, incluindo literatura cinzenta e busca manual. Os 29 estudos incluídos na revisão foram analisados e classificados segundo a hierarquia dos níveis de evidência Grading of Recommendations Assessment, Development and Evaluations (GRADE) e a confiabilidade entre os examinadores (coeficiente Kappa) foi calculada. Resultados: Foram identificados estudos que demonstraram eficácia na prevenção da síndrome mão-pé com o uso da crioterapia e hidroterapia. Evidenciaram-se resultados satisfatórios com o uso do creme de ureia na prevenção e tratamento, e o uso de piridoxina não apresentou resultados conclusivos. Foram encontrados mecanismos para identificação da síndrome e para classificação dos agentes indutores. O grupo dos taxanos predominou entre os medicamentos indutores da síndrome mão-pé. Conclusão: Existem evidências consistentes, porém não contemplam todos os fármacos indutores da síndrome e não exploram outras manifestações relacionadas às onicólises e onicomicoses. O estudo apresentou resultados que poderão auxiliar os prescritores na identificação da síndrome mão-pé, além de alternativas para prevenção e tratamento. Contudo, vale destacar a necessidade de pesquisas futuras para elucidar a etiologia e protocolos de tratamento.

Introduction: Hand-foot syndrome is an adverse reaction experienced by many cancer patients and a predictor of morbidity and mortality. Objective:To evaluate the scientific evidence related to the identification, prevention and treatment of chemotherapeutic-induced hand-foot syndrome, to identify the main signs and symptoms that enable the recognition of the syndrome, and to discuss the occurrence of onychomycosis in the context of the hand-foot syndrome. Method: This is a systematic review at MEDLINE/PubMed, Virtual Health Library and Scopus, including gray literature and manual search. The 29 studies included in the review were analyzed and graded according to the hierarchy of evidence levels Grading of Recommendations Assessment, Development and Evaluations (GRADE) and reliability among examiners (Kappa coefficient) was calculated. Results:It were identified studies that demonstrated efficacy in preventing hand-foot syndrome using cryotherapy and hydrotherapy. Satisfactory results were evidenced with the use of urea cream for prevention and treatment, and the use of pyridoxine showed inconclusive results. Mechanisms for identification of the syndrome and classification of inducing agents were found. The taxane group predominated among hand-foot syndrome inducing drugs. Conclusion: There are consistent evidences but do not include all drugs inducing the syndrome and do not explore other manifestations related to onycholysis and onychomycosis. The study presented results that may help prescribers to identify hand-foot syndrome, as well as alternatives for prevention and treatment. However, it is worth highlighting the need for future studies to elucidate the etiology and treatment protocols.

Pretreatment with different doses of dexamethasone in the prevention of docetaxel-induced hypersensitivity

This study aimed to evaluate the efficacy and safety of dexamethasone pretreatment regimen with different doses in the prevention of docetaxel-induced hypersensitivity reaction [HSR]. One hundred and sixty-two patients who had malignant tumors as determined by histology and/or cytology and received docetaxel treatments at least 2 cycles, were randomized into two groups. There were 90 patients in the study group and 72 patients in the control group. In the study group, patients received 4.5mg of oral dexamethasone once a day. Patients in the control group received 8 mg of dexamethasone twice a day. All patients received dexamethasone for 3 days, from the day before docetaxel treatment to the day after docetaxel treatment. The endpoints were hypersensitivity reaction [HSR] and other adverse effects, which were determined according to common terminology criteria for adverse event v3.0 [CTCAE 3.0]. In the study group, 10 patients had HSRs [11.1%]. While in the control group, 7 patients had HSRs [9.7%], and the main clinical symptoms of HSR were rash [3.1%], fever/chill [2.5%], angioedema [1.9%], chest discomfort [1.9%] and hypotension [0.6%]. There was no statistically significant difference between these two groups [P=0.774]. There was no significant difference in the incidence rate of adverse effect between patients in the study group and in the control group. Those adverse effects included neutropenia, decreased hemoglobin, nausea, vomiting, fatigue and fluid retention. Since no significant difference in the HSR incidence between these two groups has been found, 4.5mg of dexamethasone [qd] is as efficient and safe as 8mg [bid]

Methods Longitudinal study involving 17 women with breast cancer under treatment using Docetaxel. The patients’ pain was assessed during three chemotherapy cycles, using the tools McGill Pain Questionnaire (Br-MPQ) and the Brief Pain Inventory (BPI). Spearman’s correlation and the Mann-Whitney test were used. Results The mean pain score increased in all variables of the BPI. When comparing the total coefficients on the Pain Assessment Index, 0.20; 0.33 and 0.24 were found in the first, second and third assessment, showing a correlation between the pain intensity and the interference in all daily activities on the BPI for the second assessment. Conclusion The occurrence of pain increased, compromising the participating women’s activities of daily living.

Persistent docetaxel-induced supravenous erythematous eruption

AbstractTaxanes are drugs used to treat many types of cancer, including breast and lung cancer. The most common side effects of these drugs are neutropenia and mucositis. Signs of skin toxicity are observed in about 65% of cases and include alopecia, hypersensitivity reactions, persistent supravenous erythematous eruption, nail changes, scleroderma reactions and others. We report two cases of skin reaction to docetaxel and warn that it is not necessary to interrupt the treatment in these cases.

Relationship between Quality of Life and Nurse-led Bedside Symptom Evaluations in Patients with Chemotherapy-induced Peripheral Neuropathy

PURPOSE: This cross-sectional study aimed at determining the relationship between patient-reported quality of life (QOL) and nurse-led bedside evaluations of chemotherapy-induced peripheral neuropathy symptoms. METHODS: One hundred ninety-five patients treated at the oncology clinic at our institution were assessed using Functional Assessment of Cancer Therapy/Gynecologic Oncology Group-Neurotoxicity and nurse-led bedside examinations. The relationship between self-reported QOL and bedside examinations was evaluated using Spearman rank correlations. RESULTS: Scores of upper and lower extremity muscle strength based on the bedside examinations showed a weak negative correlation with the emotional well-being subscale of Functional Assessment of Cancer Therapy-General. Further, weak negative relationships were present between QOL and the following nurse-reported parameters: vibration perception in the hand, upper extremity muscle strength, touch and vibration perception in the feet, and tendon reflexes. CONCLUSION: Collectively, our results indicate that nurse-led bedside evaluation is a noninvasive and useful method for detecting neurotoxicity and evaluating the patient's QOL both during and after treatment.

Neo-adjuvant chemotherapy in advanced hypopharyngeal carcinoma.

Objective: The aim of this retrospective study was to find out the role of neo-adjuvant chemotherapy (NACT) in changing the management and outcome of advanced hypopharyngeal cancer patients. Materials and Methods: This is a retrospective analysis of 59 treatment naïve, advanced hypopharyngeal cancer patients presenting to our tertiary care center from April 2010 to October 2011. NACT was given as two (platinum with taxane) or three drug with (platinum, taxane with 5-flurouracil [5 FU]) as 3 weekly regimen with cisplatin and docetaxel as 75 mg/m 2 each, 5-FU as 1000 mg/m 2 . NACT was either given with the intent of achieving: (1) surgical resection (extensive soft tissue disease, oropharyngeal involvement, extensive disease with cartilage erosion) or (2) organ preservation (Bulky disease with inner cartilage erosion, exolaryngeal disease without cartilage erosion, large N3 nodes). Results: The mean age of this population was 55 years. Most (83%) of the patients had pyriform sinus (PFS) involvement. 69% patients had Stage IVa disease, 21% Stage IVb and 10% Stage III. The overall response rate was 66%, including 06% complete responses and 60% partial responses. Following NACT, resectability was achieved in 30% (10/33) and organ preservation protocol was planned after NACT in 73% (19/26) patients. The main toxicities were neutropenia (grade 3, 4, 04%; febrile neutropenia, 4%), mucositis 5%, diarrhea 5%. The median progression free survival was 20 months. Conclusions: NACT can be useful in patients with oropharyngeal involvement to achieve surgical resection and larynx preservation in patients with bulky T3 disease.

Induction might be beneficial in this setting by reducing tumor bulk and allowing definitive surgery. Aim: To analyze the impact of induction chemotherapy on locally advanced, technically unresectable oral cavity cancers. Materials and Methods: Retrospective analysis of patients with locally advanced oral cavity cancers, who were treated with neoadjuvant chemotherapy (NACT) during the period between June 2009 and December 2010. Data from a prospectively filled database were analyzed for information on patient characteristics, chemotherapy received, toxicity, response rates, local treatment offered, patterns of failure, and overall survival. The statistical analysis was performed with SPSS version 16. Results: 123 patients, with a median age of 42 years were analyzed. Buccal mucosa was the most common subsite (68.30%). Three drug regimen was utilized in 26 patients (21.10%) and the rest received two drug regimen. Resectability was achieved in 17 patients treated with 3 drug regimen (68.00%) and 36 patients receiving 2 drug regimen. Febrile neutropenia was seen in 3 patients (3.09%) receiving 2 drug regimen and in 9 patients (34.62%) receiving 3 drug regimen. The estimated median OS was not reached in patients who had clinical response and underwent surgery as opposed to 8 months in patients treated with non-surgical modality post NACT (P = 0.0001). Conclusion: Induction chemotherapy was effective in converting technically unresectable oral cavity cancers to operable disease in approximately 40% of patients and was associated with significantly improved overall survival in comparison to nonsurgical treatment.

Secondary Prophylaxis of Docetaxel Induced Diarrhea with Loperamide: Case Report

Diarrhea is a common adverse event of docetaxel with 20%-40% of incidence and severe diarrhea occurs in 5%-6%. Several treatment guidelines for chemotherapy induced diarrhea (CID) exist, however the prophylaxis for that is not well known. We describe a new prophylactic approach for the CID with loperamide. A 72-yr-old male patient with stage IV non-small-cell lung cancer developed diarrhea repeatedly after docetaxel-cisplatin chemotherapy. His diarrhea persisted despite treatment including loperamide and fasting. However, the diarrhea was successfully prevented when loperamide was given before and after the chemotherapy. To our knowledge, this is the first report of prophylactic approach for the CID with loperamide.

Third-line docetaxel chemotherapy for recurrent and metastatic gastric cancer

BACKGROUND/AIMS: To determine the efficacy and toxicity of docetaxel as a third-line therapy for patients with relapsed gastric cancer who have undergone modified oxaliplatin-fluorouracil (m-FOLFOX)-4 and modified irinotecan-fluorouracil (m-FOLFIRI) regimens. METHODS: We analyzed 33 patients who had been histologically diagnosed with adenocarcinoma of the stomach and who had progressed after m-FOLFOX-4 and m-FOLFIRI regimens. Patients were treated with cycles of 75 mg/m2 docetaxel on day 1 every 3 weeks. RESULTS: The median age of the patients was 56.0 years (range, 31.0 to 74.0), and 73% of the patients (24/33) had an Eastern Cooperative Oncology Group performance status of 0 or 1. All patients were evaluated in terms of tumor response: five (15%), nine (27%), and 19 (58%) patients experienced a partial response, stable disease, and progressive disease, respectively. The median time to progression was 2.1 months (95% confidence interval [CI], 1.63 to 2.58), and overall survival was 4.7 months (95% CI, 3.20 to 6.20), from the start of the docetaxel regimen. Assessing patients' toxicity profiles, the median number of cycles was 2.0 (range, 1.0 to 12.0). The major hematologic toxicities included grade 3 to 4 neutropenia (19/33, 58%), grade 3 to 4 thrombocytopenia (2/33, 6%), and grade 3 to 4 anemia (5/33, 15%). Neutropenic fever developed in three patients (3/33, 9%). The nonhematological toxicities were nausea and vomiting (10/33, 30%), abdominal pain (4/33, 12%), skin rash (1/33, 3%), and fluid retention (3/33, 9%). CONCLUSIONS: Docetaxel is a feasible third-line therapy regimen for patients with advanced gastric cancer after m-FOLFIRI and m-FOLFOX-4 regimens.

Efeitos colaterais cutâneos de quimioterapia com taxanos: O ponto de vista do dermatologista / Cutaneous adverse reactions to chemotherapy with taxanes: The dermatologist's point of view

Taxanos são drogas quimioterápicas cada vez mais utilizadas no tratamento adjuvante de um grande número de cânceres, principalmente câncer de mama e de pulmão. Os efeitos colaterais não cutâneos mais importantes e limitantes do uso destas drogas são neutropenia e mucosite. Os efeitos colaterais cutäneos, além de muito frequente, interfere de forma importante na qualidade de vida dos doentes. Não existem tratamentos totalmente eficazes, mas algumas orientações podem diminuir os sintomas e prevenir recidivas em novas sessões de quimioterapia.

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.

Clinical and pathological response rates of docetaxel-based neoadjuvant chemotherapy in locally advanced breast cancer and comparison with anthracycline-based chemotherapies: Eight-year experience from single centre.

Introduction: The administration of neoadjuvant chemotherapy (NACT) prior to local therapy is advantageous for women with locally advanced breast cancer (LABC), since it can render inoperable tumors resectable and can increase rates of breast conservative surgeries. Materials and Methods: We retrospectively analyzed LABC patients who received NACT from January 2000 to December 2007. Out of 3000 case records screened, 570 (19%) were LABC and 110/570 (19%) treatment-naïve patients started on NACT were analyzed. Ninety-one (37 docetaxel [D], 54 anthracycline [A]) patients were eligible for response and survival analysis. Pathological complete remission (pCR) was defined as no evidence of malignancy in both breast and axilla. Results: Median age of the whole cohort was 45 years (range 25-68 years). Premenopausal were 42% and estrogen receptor + 49.5%. Most (90%) were T4 tumors and 70% were Stage IIIB. Median numbers of preoperative cycles were six and three in the D and A group respectively. Overall clinical response rates for breast primary were 74.3% and 53.7% (CR 28.6% vs. 16.7%, P=0.58) while for axilla ORR were 75.7% vs. 54.8% (51.4% vs. 40.4% CR, P=0.77) respectively for D and A. Corresponding pCR rates were 19% vs. 13% respectively. There was no significant difference in disease-free (three-year 56.84% vs. 61.16%, P=0.80) and overall survival (three-year 70% vs. 78.5%, P=0.86) between the two groups. Conclusions: Although pCR rates were higher with docetaxel-based NACT, it did not translate into superior disease-free survival / overall survival compared to anthracycline-based chemotherapies.

Modified, weekly dosing with docetaxel and cisplatin as first-line therapy in advanced non-small cell lung cancer.

Background. Platinum-based combination chemotherapy regimens provide modest improvement in both survival and quality of life for patients with non-small cell lung cancers and docetaxel is the first agent approved for both first- and secondline treatment in patients with advanced disease. However, the regimens are associated with adverse effects. Methods. We used a modified, shortened regimen with only 2 consecutive weekly infusions of docetaxel followed by rest for 1 week, and evaluated the efficacy and toxicity profiles in patients undergoing treatment for non-small cell lung cancers. Thirty-five patients (19 men, 16 women) with advanced non-small cell lung cancers received docetaxel (35 mg/m2 i.v. infusion on days 1 and 8) with cisplatin (60 mg/m2 i.v. infusion on day 8) in 126 cycles. Results. Two of the 35 patients achieved complete response (5.7%), while 16 patients achieved partial response (45.7%). The overall response rate was 51.4% and median overall survival was 10.6 months. The toxicities were mild; the most common grades 3 and 4 toxicities were anaemia (5.6%), neutropenia (4.8%) and vomiting (5.6%). Other grades 3 and 4 non-haematological toxicities included diarrhoea (3.2%), neurotoxicity (0.8%), asthenia (0.8%) and phlebitis (0.8%). Conclusion. Combination chemotherapy with cisplatin and 2 consecutive weekly infusions of docetaxel can be considered an active and well-tolerated regimen with a good response rate and less toxicity for patients with advanced non-small cell lung cancers.

A Case of Therapy-related Acute Myeloid Leukemia associated with inv(16) / 대한진단검사의학회지

The inv(16)(p13q22) is found in de novo AML and is closely associated with the FAB subtype M4eo. The inv(16) is rarely reported in therapy-related AML (t-AML) patients. Herein, we report a case of t-AML with inv(16) after combination chemotherapy using antimitotic agent and alkylating agent (cis-platin-paclitaxel) for ovarian serous cystadenocarcinoma.

Doxetaxel in previously treated non-small cell lung cancer patients: clinical efficacy and quality of life.

Docetaxel (Taxotere) is one of the most active new generation chemotherapy agents against advanced non-small cell lung cancer (NSCLC). This study aimed to determine the activity, toxicity and impact on the quality of life (QOL) in patients treated with docetaxel after failure with first-line platinum-based combination chemotherapy. Twenty-one patients with advanced NSCLC who had previously received the platinum-containing regimen were treated with docetaxel 75 mg/m2 every 3 weeks. QOL was assessed at intervals during the treatment period using the Functional Assessment of Cancer Treatment - Lung (FACT-L). Of the 21 patients enrolled, 16 were able to be evaluated for response and 20 were included in the toxicity analysis. The median age was 57 (range, 39-75 years). A median of 3 cycles was given (range, 1-9). Of the 16 evaluatable patients, there was one partial response (6.3%) and 4 with stable disease (25%). The median survival time was 8.1 months and the 1-year survival rate was 25%. Myelosuppression and peripheral neuropathy were the major toxicities. Grade 3/4 neutropenia and paresthesia occurred in 6 patients (30%) and 3 patients (15%), respectively. There was no significant improvement or deterioration in the overall FACT-L, TOI (Trial Outcome Index) and lung cancer symptom scores during the treatment. Symptom improvement was noted, in particular for shortness of breath and weight loss in the majority of patients. It is concluded that docetaxel is a well tolerated second-line treatment for recurrent NSCLC. Of particular importance was that the treatment did not negatively impact the overall quality of life, on the contrary, did palliate some of the lung cancer related dash symptoms in many patients.
