Conclusion: It was understood that the nurse's perception highlights the importance of care planning, including immediate intervention, event registration, and patient follow-up after extravasation, to perform specialized care and with greater safety.

Desafios terapêuticos da mucosite oral em oncopediatria / Therapeutic challenges of oral mucositis in pediatric oncology

O Neuroblastoma (NB) é uma neoplasia do sistema nervoso simpático, e o segundo tumor sólido maligno extracraniano mais comum da infância. Na terapia antineoplásica, complicações orais podem ser observadas, dentre elas a mucosite oral (MO). Trata-se de uma inflamação aguda da mucosa, proveniente da toxicidade dos quimioterápicos. Este relato de caso enfatiza o manejo da MO, bem como sua influência na condição sistêmica e qualidade de vida. Paciente do sexo feminino, nove anos, apresentou recidiva de NB metastático, após tratamento de primeira linha. Admitida na unidade hospitalar para tratamento oncológico na enfermaria de pediatria oncológica, queixando-se de dor intensa em cavidade bucal e orofaringe, associada a pancitopenia severa febril. Ao exame físico apresentava disfagia e déficit ponderal grave, que debilitava a deglutição da própria saliva. O exame intraoral revelou lesões de MO grau 3, segundo a Organização Mundial de Saúde (OMS), em lábios, gengiva anterior e orofaringe. O tratamento consistiu em remoção de debris local, higiene da cavidade bucal com clorexidina 0,12% e utilizando haste flexível de algodão estéril tipo "Swab", visando controle microbiano local, diariamente. Além disso, foi aplicado no leito eritematoso e hemorrágico fotobiomodulação (660 nm, 50 mW, 2 J/cm2, 90 segundos) pontualmente nas áreas do leito da lesão e em varredura na região de orofaringe (sessões intercaladas). Foi prescrito acetato de racealfatocoferol (vitamina E) para ação antioxidante e hidratação dos lábios. Concomitante a mucosite, a paciente apresentou pancitopenia febril severa, sendo necessário uso de cefepima 150 mg/kg/dia, com coleta prévia de hemoculturas, fator estimulador de colônias de granulócitos, Fluconazol, hidratação e suporte nutricional. As hemoculturas foram negativas. As consequências da mucosite contribuíram para desnutrição e piora da qualidade de vida. Conclui-se que a intervenção odontológica em interdisciplinaridade, possibilitou o restabelecimento físico e emocional, possibilitando melhor uma qualidade de vida da paciente (AU).

Neuroblastoma (NB) is a neoplasia of the sympathetic nervous system and the second most common extracranial malignant solid tumor in childhood. In antineoplastic therapy, oral complications can be observed in antineoplastic therapy, among them oral mucositis (OM). It is an acute mucosa inflammation resulting from the toxicity of chemotherapy drugs. This case report emphasizes the management of OM and its influence on the systemic condition and quality of life. A female patient, nine years old, presented a recurrence of metastatic NB after first-line treatment. She was admitted to the hospital unit for oncological therapy in the pediatric oncology ward, complaining of severe pain in the oral cavity and oropharynx associated with severe febrile pancytopenia. On physical examination, she presented dysphagia and severe weight deficit, which weakened the swallowing of her saliva. According to the World Health Organization (WHO), the intraoral exam revealed third-grade OM lesions on the lips, anterior gum, and oropharynx. Treatment consisted of removing local debris, cleaning the oral cavity with 0.12% chlorhexidine, and using a flexible, sterile cotton swab, aiming for daily local microbial control. In addition, photobiomodulation (660 nm, 50 mW, 2 J/cm2, 90 seconds) was applied to the erythematous and hemorrhagic bed, punctually in the areas of the lesion and sweeps in the oropharynx region (interspersed sessions). Racealphatocopherol acetate (vitamin E) was prescribed for antioxidant action and lip hydration. Concomitant with mucositis, the patient had severe febrile pancytopenia, requiring cefepime 150 mg/kg/day, with previous collection of blood cultures, granulocyte colony-stimulating factor, fluconazole, hydration, and nutritional support. Blood cultures were negative. The consequences of mucositis contributed to malnutrition and worsened quality of life. It is concluded that the interdisciplinary dental intervention enabled physical and emotional restoration, enabling a better quality of life for the patient (AU).

Mitigation of cisplatin induced nephrotoxicity by casticin in male albino rats / Mitigação da nefrotoxicidade induzida pela cisplatina pela casticina em ratos albinos machos

Cisplatin (CP) is a commonly used, powerful antineoplastic drug, having numerous side effects. Casticin (CAS) is considered as a free radical scavenger and a potent antioxidant. The present research was planned to assess the curative potential of CAS on CP persuaded renal injury in male albino rats. Twenty four male albino rats were distributed into four equal groups. Group-1 was considered as a control group. Animals of Group-2 were injected with 5mg/kg of CP intraperitoneally. Group-3 was co-treated with CAS (50mg/kg) orally and injection of CP (5mg/kg). Group-4 was treated with CAS (50mg/kg) orally throughout the experiment. CP administration substantially reduced the activities of catalase (CAT), superoxide dismutase (SOD), peroxidase (POD), glutathione S-transferase (GST), glutathione reductase (GSR), glutathione (GSH) content while increased thiobarbituric acid reactive substances (TBARS), and hydrogen peroxide (H2O2) levels. Urea, urinary creatinine, urobilinogen, urinary proteins, kidney injury molecule-1 (KIM-1), and neutrophil gelatinase-associated lipocalin (NGAL) levels were substantially increased. In contrast, albumin and creatinine clearance was significantly reduced in CP treated group. The results demonstrated that CP significantly increased the inflammation indicators including nuclear factor kappa-B (NF-κB), tumor necrosis factor-α (TNF-α), Interleukin-1β (IL-1β), Interleukin-6 (IL-6) levels and cyclooxygenase-2 (COX-2) activity and histopathological damages. However, the administration of CAS displayed a palliative effect against CP-generated renal toxicity and recovered all parameters by bringing them to a normal level. These results revealed that the CAS is an effective compound having the curative potential to counter the CP-induced renal damage.

A cisplatina (CP) é uma droga antineoplásica poderosa, comumente usada, com vários efeitos colaterais. Casticin (CAS) é considerado um eliminador de radicais livres e um potente antioxidante. A presente pesquisa foi planejada para avaliar o potencial curativo da CAS em lesão renal induzida por PC em ratos albinos machos. Vinte e quatro ratos albinos machos foram distribuídos em quatro grupos iguais. O Grupo 1 foi considerado grupo controle. Os animais do Grupo 2 foram injetados com 5 mg / kg de PB por via intraperitoneal. O Grupo 3 foi cotratado com CAS (50 mg / kg) por via oral e injeção de CP (5 mg / kg). O Grupo 4 foi tratado com CAS (50 mg / kg) por via oral durante todo o experimento. A administração de CP reduziu substancialmente as atividades de catalase (CAT), superóxido dismutase (SOD), peroxidase (POD), glutationa S-transferase (GST), glutationa redutase (GSR), glutationa (GSH), enquanto aumentou as substâncias reativas ao ácido tiobarbitúrico (TBARS) e níveis de peróxido de hidrogênio (H2O2). Os níveis de ureia, creatinina urinária, urobilinogênio, proteínas urinárias, molécula 1 de lesão renal (KIM-1) e lipocalina associada à gelatinase de neutrófilos (NGAL) aumentaram substancialmente. Em contraste, a albumina e a depuração da creatinina foram significativamente reduzidas no grupo tratado com PC. Os resultados demonstraram que a CP aumentou significativamente os indicadores de inflamação, incluindo fator nuclear kappa-B (NF-κB), fator de necrose tumoral-α (TNF-α), interleucina-1β (IL-1β), interleucina-6 (IL-6) níveis e atividade da ciclooxigenase-2 (COX-2) e danos histopatológicos. No entanto, a administração de CAS apresentou um efeito paliativo contra a toxicidade renal gerada por CP e recuperou todos os parâmetros, trazendo-os a um nível normal. Estes resultados revelaram que o CAS é um composto eficaz com potencial curativo para combater o dano renal induzido por CP.

Consensus on clinical diagnosis, treatment, and prevention of chemotherapy-induced neutropenia in China (2023 edition) / 中华肿瘤杂志

Chemotherapy-induced neutropenia (CIN) is a common hematological adverse events and dose-limiting toxicities of chemotherapy. CIN may lead to dose reduction and delay of chemotherapeutic agents, febrile neutropenia and severe infection, which results in increased treatment cost, reduced efficacy of chemotherapy, and even life-threatening morbidities. Assessment of risk of CIN, early detection of FN and infection, and proper prevention and treatment play a crucial role in reducing the occurrence of CIN-related morbidities, improving patient treatment safety and anticancer efficacy. Based on evidence and expert opinion, the expert committee of Chinese Anti-Cancer Association issued "the consensus on diagnosis and treatment of chemotherapy-induced neutropenia in China (2023 edition)", which is an update version of the 2019 edition, aiming to provide reference for the diagnosis and treatment of CIN for Chinese oncologists.

Aldehyde dehydrogenase 2 rs671 genetic polymorphisms are associated with chemotherapy-induced nausea and vomiting / 南方医科大学学报

OBJECTIVE@#To investigate the correlation between aldehyde dehydrogenase 2 (ALDH2) rs671 polymorphisms and chemotherapy-induced nausea and vomiting (CINV).@*METHODS@#A total of 90 Chinese patients with malignant tumors receiving chemotherapy for the first time were recruited in this study. The occurrence of CINV was observed within 120 h after treatment with docetaxel and cis-platinum chemotherapy (DP regimen). The data of the patients (including age, gender, tumor stage, habitual alcohol consumption, motion sickness, morning sickness, and average sleep time prior to chemotherapy) were collected through a questionnaire. ALDH2 rs671 polymorphisms of the patients were analyzed using a multiple single nucleotide polymorphism genotyping, and the Hardy-Weinberg equation was used for genetic linkage analysis. The correlations between the factors including ALDH2 rs671 polymorphisms and the occurrence of CINV were analyzed.@*RESULTS@#The incidence of CINV was 48.9% among the patients receiving their first chemotherapy with DP regimen. Univariate analysis indicated that the genetic polymorphisms of ALDH2 rs671 were significantly correlated with the occurrence of CINV (P < 0.05). Multivariate logistic analysis indicated that ALDH2 rs671 mutation (OR: 3.019, 95% CI: 1.056-8.628, P < 0.05) and average sleep time prior to chemotherapy no longer than 6 h (OR: 2.807, 95% CI: 1.033-7.628, P < 0.05) were risk factors for CINV in patients with malignant tumors receiving the first chemotherapy with DP regimen.@*CONCLUSION@#ALDH2 gene mutation at rs671 is a risk factor contributing to the occurrence of CINV, and understanding of the underlying mechanism may help to more effectively control the occurrence of CINV.

Carcinogenic drug exposure among health-sector workers: the need for exposure assessment and surveillance / Exposición a medicamentos cancerígenos en trabajadores del sector de la salud: necesidad de evaluación y vigilancia de la exposición / Exposição a fármacos carcinogênicos entre profissionais de saúde: necessidade de avaliação e vigilância da exposição

ABSTRACT Antineoplastic drugs (ANDs) used for chemotherapy can cause secondary cancers in treated patients and can pose carcinogenic risks to health-sector workers anywhere along these drugs' life cycle in a facility, from production to patient administration. Several PAHO/WHO Collaborating Centers (CCs) have experience addressing these hazards in the health sector. The objectives of this report are four-fold: 1) Provide an overview of longstanding research and prevention efforts, led by PAHO/WHO and its Occupational Health CCs, aimed at reducing the burden of occupational cancer in the Americas; 2) Discuss how robust AND exposure assessment and educational/outreach work by PAHO CCs can form the basis of exposure mitigation efforts among health-sector workers; 3) Through the presentation of original AND exposure assessment data from a pharmaceutical compounding facility in Chile, highlight relatively inexpensive methods by which such data can be generated; and 4) Discuss how effective, periodic environmental surveillance in healthcare facilities results in the identification of AND contamination in the work environment and enables the implementation of low-cost, high-impact interventions to reduce the risk of occupational cancer in health-sector workers, including in limited-resource settings. The risk of health-sector worker exposure to ANDs and other hazardous drugs is an important issue for inclusion within PAHO/WHO's broader efforts at reducing the impact of occupational cancer in the Americas. This report demonstrates that a wide range of accessible AND-exposure mitigation strategies are feasible at both a facility and a national policy level across the hemisphere.

ABSTRACT Objective: to identify the locoregional adverse effects of administering intravenous oncologic therapy in women with advanced breast cancer. Method: this was an integrative literature review using the PubMed/MEDLINE, CINAHL, LILACS, and EMBASE databases, without a time cut, in addition to a reverse search of the selected articles updated until May 2022. The population included women with advanced breast cancer undergoing intervention with intravenous oncologic therapy with chemotherapy, hormone therapy, or monoclonal antibody, and the outcome assessed locoregional adverse effects. Results: 2,789 studies were identified, and the final sample consisted of 8 clinical trials and 1 retrospective observational study, all of which were international studies published from 1986 to 2018. Predominantly, patients with stage IV breast cancer, were aged 50 years or older, and had multiple metastases. Locoregional adverse effects were phlebitis, ulceration and/or necrosis, pain, erythema, and unspecified injection site reaction. The studies did not detail the type of venous catheter, the osmolarity of the drugs, and preventive care to reduce these adverse effects. Conclusion: the evidence from these articles showed that locoregional adverse effects are present in efficacy research of oncologic drugs in women with advanced breast cancer. Nonetheless, the safety of administering cancer drugs is not elucidated in this review, indicating the need for follow-up studies of adverse effects.

Subclinical Systolic Dysfunction during Chemotherapy for Breast Cancer

Abstract Background Cardiotoxicity is the main complication related to cancer therapy. Studies indicate that global longitudinal strain is an early detector of subclinical dysfunction of the left ventricle, preceding the decline in ejection fraction (EF). However, the reproducibility of such methodology has not been tested outside specialized centers. Objectives To assess the frequency of subclinical cardiotoxicity and to compare global longitudinal strain and EF measurements during the clinical course of patients undergoing chemotherapy for breast cancer. Methods This was an observational prospective study of 78 adult women who underwent serial echocardiograms (baseline and 1, 3, and 6 months after the beginning of chemotherapy), to evaluate biplane and 3D EF and global longitudinal strain. Cardiotoxicity and subclinical dysfunction were defined according to American Society of Echocardiography/European Association of Cardiovascular Imaging criteria. Statistical significance was set at p < 0.05. Results The mean age of the patients was 50.1 ± 11.48 years. The frequency of subclinical cardiotoxicity (defined by global longitudinal strain) was 14.9% after 30 days of chemotherapy, 16.7% after 3 months, and 19.7% after 6 months, compared to 4.5%, 3%, and 6.6%, respectively, when clinical cardiotoxicity was determined according to EF. The group that developed subclinical cardiotoxicity by 30 days (group A) had a higher frequency of clinical cardiotoxicity at 3 months (p=0.028) and a lower mean biplane EF after 30 days (p= 0.036) than the group that showed no evidence of subclinical cardiotoxicity (group B). Conclusion Subclinical cardiotoxicity was frequent and began early, being associated with a drop in EF during the clinical course.

Cutaneous adverse events to systemic antineoplastic therapies: a retrospective study in a public oncologic hospital

Abstract Background: Mucocutaneous adverse events are common during anticancer treatment, with variable consequences for the patient and their therapeutic regimen. Objective: To evaluate the most common adverse events, as well as the drugs associated with their appearance and the consequences for cancer treatment. Methods: A retrospective study was carried out through the analysis of patients treated at the Clinical Dermatology Unit of a public oncologic hospital. Results: A total of 138 patients with 200 adverse events were evaluated. The most commonly identified adverse events were nail and periungual changes (20%), papulopustular eruptions (13%), acneiform eruptions (12%), hand-foot syndrome (6.5%), hand-foot skin reaction (6%), and xerosis (6%). The most frequently associated antineoplastic treatment groups were classical chemotherapy (46.2%), target therapy (32.3%), and other non-antineoplastic drugs used in neoplasia protocols (16.5%). Of the total number of patients, 17.4% had their treatment suspended or changed due to a dermatological adverse event. Study limitations: Retrospective study and analysis of patients who were referred for specialized dermatological examination only, not allowing the assessment of the actual incidence of adverse events. Conclusion: A wide variety of dermatological manifestations are secondary to antineoplastic treatment with several different drugs resulting, not rarely, in the interruption or modification of therapeutic regimens.

O câncer de colo uterino é o quarto tipo mais incidente e fatal entre as mulheres no Brasil e no mundo, o que representa mundialmente em torno de 600 mil novos casos e mais de 300 mil mortes a cada ano. Assim como o diagnóstico, o tratamento da doença pode impactar de forma significativa a qualidade de vida dessas pacientes. A aplicação de questionários que avaliem os diferentes aspectos da qualidade de vida das mulheres afetadas por esse câncer é uma ferramenta relevante, pois auxilia na compreensão e identificação dos principais danos relacionados ao tratamento. Este trabalho visa analisar a literatura atual que investiga e relata os principais efeitos à qualidade de vida de mulheres com câncer de colo uterino associados a diferentes modalidades terapêuticas e, desse modo, contribuir nas escolhas de tratamento e manejo clínico que resultem em menores impactos à qualidade de vida dessas mulheres.(AU)

Cervical cancer is the fourth most incident and fatal cancer type among women in Brazil and worldwide. This data represents around 600 thousand new cases worldwide each year and more than 300 thousand lives lost. Both diagnosis and treatment can significantly impact the quality of life of cervical cancer patients. The application of questionnaires that assess the different aspects of the quality of life of women affected by this cancer is a relevant tool, as it helps to understand and identify the main damages related to the treatment. This article aims to analyze the current literature that reports the main effects on the quality of life of women with cervical cancer associated with different therapeutic modalities. In this way, the review could assist in the treatment choices that imply less impact on the quality of life of these women.(AU)

Efficacy of Wen-Luo-Tong on Peripheral Neuropathy Induced by Chemotherapy or Target Therapy: A Randomized, Double-Blinded, Placebo-Controlled Trial / 中国结合医学杂志

OBJECTIVE@#To evaluate the efficacy of Wen-Luo-Tong Granules (WLT) local administration in the treatment of patients with peripheral neuropathy (PN) induced by chemotherapy or target therapy.@*METHODS@#This study is a randomized, double-blinded, and placebo-controlled trial. Seventy-eight patients with PN induced by chemotherapy or target therapy were enrolled from China-Japan Friendship Hospital between July 2019 and January 2020. They were randomly assigned to WLT (39 cases) and control groups (39 cases) using a block randomization method. The WLT group received WLT (hand and foot bath) plus oral Mecobalamin for 1 week, while the control group received placebo plus oral Mecobalamin. The primary endpoint was PN grade evaluated by the National Cancer Institute-Common Toxicity Criteria for Adverse Events (NCI-CTCAE). The secondary endpoints included quantitative touch-detection threshold, neuropathy symptoms, Quality of Life Questionnaire-Chemotherapy Induced Peripheral Neuropathy (QLQ-CIPN20), and Quality of Life Questionnaire-Core30 (QLQ-C30).@*RESULTS@#After treatment, the PN grade in the WLT group was significantly lower than that in the control group (1.00 ± 0.29 vs. 1.75 ± 0.68, P<0.01). The total effective rate in the WLT group was significantly higher than that in the control group (82.05% vs. 51.28%, P<0.01). Compared with the control group, the touch-detection thresholds at fingertips, neuropathy symptom score, QLQ-CIPN 20 (sensory scale, motor scale, autonomic scale, and sum score), and QLQ-C30 (physical functioning, role functioning, emotional functioning, and global health) in the WLT group significantly improved after treatment (P<0.01 or P<0.05).@*CONCLUSION@#WLT local administration was significantly effective in the treatment of patients with PN induced by chemotherapy or target therapy.

Expert consensus on the diagnosis and treatment of anticancer drug-induced interstitial lung disease / 中华肿瘤杂志

Drug-induced interstitial lung disease (DILD) is the most common pulmonary adverse events caused by anti-cancer treatment. In recent years, with the development of clinical oncology, a large amount of novel anti-cancer drugs have been approved and widely used in clinical practice, and the incidence of anti-cancer drug related DILD is gradually increasing. DILD lacks specific clinical manifestations or diagnostic criteria. If not treated properly, it may leads to interruption or discontinuation of anti-cancer treatment, or even become life threat in severe cases. Therefore, the Anti-cancer Drug-induced Interstitial Lung Disease Management Group have reached a consensus on the diagnosis and management of anti-cancer DILD after several rounds of discussion. This consensus aims to improve clinicians' awareness of anti-cancer drug related-DILD and proposes an algorithm for the diagnosis and treatment of this disease, and to improve patients' prognosis and quality of life.

Expert consensus on the management of adverse events of CDK4/6 inhibitors in breast cancer / 中华肿瘤杂志

Cyclin-dependent kinases 4/6 (CDK4/6) inhibitors are anti-tumor agents for the treatment of hormone receptor-positive breast cancer. Palbociclib, abemaciclib and dalpiciclib have been approved for the treatment of breast cancer in China. Common adverse effects of CDK4/6 inhibitors include bone marrow suppression, gastrointestinal toxicities, liver dysfunction, and skin or subcutaneous tissue adverse reactions (AEs). The Breast Cancer Expert Group of Chinese Society of Clinical Oncology (CSCO) summarized the incidence, clinical manifestations, and grading of the AEs. This expert consensus reports measures of AE management on the basis of experience of clinical practice and the latest advances worldwide, aiming to guide clinical practice by the way of managing AE and help to choose the best treatment regimen.

Investigation of teratogenic effects of letrozole on fetal bone development / Investigación de los efectos teratogénicos de letrozol en el desarrollo óseo fetal

SUMMARY: Letrozole is mainly used for the treatment of unexplained infertility, breast cancer and polycystic ovarian syndrome, with secondary use in ovarian stimulation. In cases of unexpected or unknown pregnancy during the use of letrozole, letrozole may cause a teratogenic effect on the fetus. In this reason, in this study, we aimed to determine the effect of letrozole on fetal bone development. In this study, 32 pregnant Wistar albino rats were used. The rats were divided into four groups: Control (saline) and high; 0.3 mg/kg, medium; 0.03 mg/kg, low; 0.003 mg/ kg letrozole. Saline and letrozole were administered in 100 mL solutions by intraperitonaly from day 11 to day 15 of pregnancy. The skeletal system development of fetuses was examined with double skeletal staining, immunohistochemical staining methods and mineral density scanning electron microscopy. A total of 100 fetuses from female rats, 25 in each group, were included in the study. As a result of that, ossification rates were observed to decrease depending on the dose of letrozole in the forelimb limb (scapula, humerus, radius, ulna) and hindlimb (femur, tibia, fibula) limb bones. As a result of the statistical analysis, a statistically significant decrease was found in the ossification rates of all bones between the control group and low, medium, high letrozole groups (p<0.001). Exposure to letrozole during pregnancy adversely affected ossification and bone growth. However, the teratogenic effects of letrozole are unclear. Therefore, it needs to be investigated more extensively.

RESUMEN: Letrozol se usa principalmente para el tratamiento de la infertilidad inexplicable, el cáncer de mama y el síndrome de ovario poliquístico, con estimulación ovárica de uso secundario. En casos de embarazo inesperado o desconocido durante el uso de letrozol, puede causar un efecto teratogénico en el feto. Por esta razón, en este estudio, nuestro objetivo fue determinar el efecto de letrozol en el desarrollo óseo fetal. Se utilizaron 32 ratas albinas Wistar preñadas las cuales se distribuyeron en cuatro grupos: Control (solución salina) y alta; 0,3 mg/kg, medio; 0,03 mg/kg, bajo; 0,003 mg/kg de letrozol. Se administró solución salina y letrozol en soluciones de 100 mL por vía intraperitoneal desde el día 11 hasta el día 15 de la preñez. El desarrollo del sistema esquelético de los fetos se examinó con tinción esquelética doble, métodos de tinción inmunohistoquímica y microscopía electrónica de barrido de densidad mineral. Se incluyeron en el estudio un total de 100 fetos de ratas hembra, 25 en cada grupo. Como resultado, se observó que las tasas de osificación disminuían dependiendo de la dosis de letrozol en los huesos de los miembros torácicos (escápula, húmero, radio, ulna) y de las miembros pélvicos (fémur, tibia, fíbula). Se encontró una disminución estadísticamente significativa en las tasas de osificación de todos los huesos entre el grupo control y los grupos de letrozol bajo, medio y alto (p<0,001). La exposición a letrozol durante la preñez afectó negativamente la osificación y el crecimiento óseo. Sin embargo, los efectos teratogénicos del letrozol no están claros por lo que debe ser investigado más extensamente.

Obstrução lacrimal pós-tratamento oncológico: revisão de literatura / Lacrimal drainage system obstruction after cancer treatment: a literature review

RESUMO A obstrução de via lacrimal é uma possível complicação decorrente de tratamentos oncológicos sistêmicos e locais. A epífora crônica gera grande impacto na qualidade de vida desses pacientes, e, como a fibrose terminal da via lacrimal pode necessitar de procedimentos complexos para sua resolução, é importante estarmos atentos a esse efeito adverso, com o objetivo de reconhecê-lo e tratá-lo precocemente, ou mesmo preveni-lo. Nesta revisão da literatura, os autores analisam todos os agentes quimioterápicos e radioterápicos associados à obstrução lacrimal e descrevem os mecanismos, a frequência, os tratamentos e a profilaxia. Os tratamentos oncológicos associados à obstrução lacrimal foram: radioterapia em cabeça e pescoço (dosagem acima de 45 a 75Gy), radioiodoterapia (dosagem acima de 150mCi) e quimioterapia com 5-FU, S-1, capecitabine e docetaxel. A obstrução lacrimal pode ser irreversível, e a intubação profilática das vias lacrimais é uma possibilidade descrita de tratamento profilático em casos de radioterapia e uso do 5-FU, S-1 e docetaxel. O tratamento cirúrgico de todos os casos é a dacriocistorrinostomia.

ABSTRACT Lacrimal duct obstruction can be a side effect of systemic and/or local cancer treatments. Chronic epiphora has a great impact on the quality of life of oncological patients. Since terminal fibrosis of the lacrimal system may require complex procedures, it is important to be aware of this adverse effect in order to recognize and treat it, or even prevent it. A literature review was performed to identify all types of systemic cancer treatment associated with lacrimal obstruction and to describe the mechanisms, frequency, treatment, and prophylaxis. The oncological treatments associated with lacrimal obstruction were head and neck radiotherapy (dosage above 45-75 Gy), radioiodine therapy (dosage above 150 mCi), and chemotherapy with 5-FU, S-1, Capecitabine and Docetaxel. Depending on the dose, this complication may be irreversible. Prophylactic intubation of the lacrimal system is an option for prophylaxis in cases of radiotherapy, use of 5-FU, S-1, and Docetaxel. Final surgical treatment is dacryocystorhinostomy.

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.

Recomendaciones para el manejo de la cardiotoxicidad relacionada con el tratamiento del cáncer. Primera parte / Recommendations for the management of cardiotoxicity related to cancer treatment. Part one / Recomendações para a gestão de cardiotoxicidade relacionada com o tratamento do câncer. Primeira parte

Las nuevas terapias oncológicas han logrado aumentar la sobrevida del paciente con cáncer, observando, sin embargo, un incremento de la morbilidad y mortalidad vinculadas a sus efectos secundarios. El desarrollo de eventos cardiovasculares adversos impacta negativamente en el pronóstico durante el tratamiento del cáncer, pero también en los supervivientes al cáncer, donde las enfermedades cardiovasculares (ECV) y las segundas neoplasias son la principal causa de muerte1-5. La cardiotoxicidad inducida por el tratamiento del cáncer se define como el conjunto de ECV derivadas de los tratamientos oncológicos. Su manifestación es variada e incluye el desarrollo de disfunción ventricular, insuficiencia cardíaca (IC), isquemia miocárdica, hipertensión arterial y arritmias, entre otras. Puede ser consecuencia tanto del efecto directo del tratamiento sobre la estructura y función cardíacas, como del desarrollo acelerado de ECV6-9. Frecuentemente se utiliza el término cardiotoxicidad como sinónimo de disfunción ventricular por quimioterapia (DV-QT). Dado que la cardiotoxicidad abarca un espectro más amplio de afectación cardiovascular, creemos conveniente hablar de DV-QT para referirnos a la afectación de la función sistólica del ventrículo izquierdo. La DV-QT y el desarrollo de IC representan una de las complicaciones más temidas por su impacto pronóstico en la esfera cardiovascular y oncológica, dado que limitan el arsenal terapéutico para el tratamiento del cáncer5,10. Han sido creadas diversas sociedades de cardio-onco-hematología con el fin de generar recomendaciones de práctica clínica y formar profesionales capacitados para el manejo de las complicaciones cardiovasculares del tratamiento del cáncer11. La cardio-oncología es una disciplina en creciente y continuo desarrollo. Creemos que es fundamental realizar tareas de formación médica continua, así como también estimular el trabajo conjunto de diversas especialidades para brindar una mejor asistencia. Este texto es el resultado del trabajo de un equipo multidisciplinario que incluye cardiólogos, hematólogos y oncólogos, y pretende brindar información a los integrantes del equipo de salud involucrados en la asistencia de pacientes oncológicos. Debido a su extensión, hemos decidido fraccionar el contenido en tres partes para facilitar su publicación.

New oncological therapies have been successful in increasing cancer patient survival, but they have also led to an increase in morbidity and mortality linked to their side effects. During cancer treatment, the development of cardiovascular side effects has a negative impact in prognosis, but also in cancer survivors, in whom cardiovascular diseases and secondary malignancies are the main cause of death. Cancer related cardiotoxicity is defined as the development of cardiovascular diseases related to cancer treatment. Clinical presentation is broad involving ventricular dysfunction, heart failure, myocardial ischemia, arterial hypertension and arrhythmias among others. This may result from the direct cardiovascular effect of a cancer treatment or accelerated development of cardiovascular diseases. Frequently, in the literature cardiotoxicity and chemotherapy related ventricular dysfunction are used as synonyms. However, cardiotoxicity includes a broad spectrum of cardiovascular manifestations, thus in this text we refer to chemotherapy related ventricular dysfunction as the presence of left ventricular systolic impairment. Chemotherapy related ventricular dysfunction and heart failure are two of the most feared complications of cancer treatment due to its impact on cardiovascular and oncological prognosis, affecting treatment options. Numerous worldwide cardio-onco-hematology societies have emerged to generate clinical practice guidelines and improve the diagnosis and evaluation of cardiovascular cancer treatment side effects. Cardio-Oncology is a discipline in continuous growth and development. We strongly believe that continuum medical education and a multidisciplinary approach is necessary to provide a quality health care. This text is the result of a multidisciplinary work involving cardiologists, hematologists and oncologists. It is our goal to provide information to the health care team involved in the assistance of cancer patients. Due to its extension, it will be published in three parts.

O desenvolvimento de novas terapias oncológicas levou a um aumento na sobrevida dos pacientes, mas ao mesmo tempo traz consigo morbidades relacionadas aos tratamentos. O desenvolvimento de efeitos cardiovasculares adversos tem um impacto negativo no prognóstico dos pacientes em tratamento, bem como nos pacientes considerados curados, nos quais doença cardiovascular e malignidades secundárias são as principais causas de morte. Cardiotoxicidade relacionada ao câncer é definida como o desenvolvimento de doença cardiovascular secundária ao tratamento. A gama de apresentações clínicas é ampla, podendo se manifestar como disfunção ventricular, insuficiência cardíaca, isquemia miocárdica, hipertensão arterial, arritmias, entre outras. Isto pode ser resultante de desenvolvimento e progressão acelerados de doença cardiovascular ou por efeito direto das terapias. Frequentemente é dito na literatura que cardiotoxicidade e disfunção ventricular relacionada à quimioterapia são sinônimos. Entretanto, cardiotoxicidade engloba um amplo espectro de manifestações cardiovasculares. Neste texto, portanto, nos referimos à disfunção ventricular causada por quimioterápicos exclusivamente como a presença de disfunção sistólica ventricular esquerda. Disfunção ventricular relacionada à quimioterapia e insuficiência cardíaca são duas das mais temidas complicações do tratamento oncológico devido ao seu impacto no prognóstico cardiovascular e oncológico, podendo afetar ainda a escolha e manutenção das opções terapêuticas. Diversas sociedades cardio-onco-hematológicas surgiram ao redor do mundo com o objetivo de gerar diretriz clínicas práticas e melhorar o diagnóstico e tratamento das complicações cardiovasculares resultantes das terapias oncológicas. A cardio-oncologia é uma disciplina em contínuo crescimento e desenvolvimento. Nós acreditamos fortemente que educação médica continuada e uma abordagem multidisciplinar são necessárias para um cuidado médico de qualidade. Este texto é o resultado de um trabalho multidisciplinar envolvendo cardiologistas, hematologistas e oncologistas. Nosso objetivo é de oferecer informação à equipe de cuidados em saúde envolvido na assistência destes pacientes. Devido à sua extensão, este texto será publicado em três partes.
