Hormone therapy in the treatment of breast cancer and main outcomes in sexuality

Hormone-dependent breast cancer has growth factors that respond positively to the hormones estrogen and progesterone. Thus, adjuvant endocrine therapy causes decreased or undetectable serum levels of these hormones. However, this treatment can have side effects that compromise the sexual health of patients, such as dyspareunia, vaginal dryness and decreased libido. In this scenario, the objective of this work was to document the main outcomes in sexuality in women after treatment for hormonepositive breast cancer. Thus, this is an integrative literature review, in which the following databases were used: U.S. National Library of Medicine (PubMed), Virtual Health Library (BVS), SCOPUS and Scientific Electronic Library Online (SCIELO), using the descriptors: "sexuality", "antineoplastic agents, hormonal" and "breast neoplasms", joined by the Boolean operator "AND". Full articles published in the last 5 years (2017-2022) were included; written in Portuguese or English. Articles dealing with non-hormone-dependent or metastatic breast cancer, or with patients younger than 18 years, or articles that did not answer the research question were excluded. In total, 26 articles were identified, of which 7 comprised the final sample of this review. A total of 3,850 women participated in the included studies. The main sexual dysfunctions found were: dyspareunia, hot flashes, decreased libido, vaginal dryness, breast tenderness, self-image concerns and hair loss. The symptom vaginal dryness was the most prevalent, mentioned in 71.4% of the articles included. In view of the adverse effects listed in this review, there is a need to carry out more studies on this topic, since the diagnosis of this comorbidity brings clinical, psychological, emotional, sociocultural and economic outcomes for the patient. Thus, a multidisciplinary team must assertively address these complaints to improve the overall quality of life of these women (AU)

Efficacy and safety of LY01005 versus goserelin implant in Chinese patients with prostate cancer: A multicenter, randomized, open-label, phase III, non-inferiority trial / 中华医学杂志(英文版)

BACKGROUND@#LY01005 (Goserelin acetate sustained-release microsphere injection) is a modified gonadotropin-releasing hormone (GnRH) agonist injected monthly. This phase III trial study aimed to evaluated the efficacy and safety of LY01005 in Chinese patients with prostate cancer.@*METHODS@#We conducted a randomized controlled, open-label, non-inferiority trial across 49 sites in China. This study included 290 patients with prostate cancer who received either LY01005 or goserelin implants every 28 days for three injections. The primary efficacy endpoints were the percentage of patients with testosterone suppression ≤50 ng/dL at day 29 and the cumulative probability of testosterone ≤50 ng/dL from day 29 to 85. Non-inferiority was prespecified at a margin of -10%. Secondary endpoints included significant castration (≤20 ng/dL), testosterone surge within 72 h following repeated dosing, and changes in luteinizing hormone, follicle-stimulating hormone, and prostate specific antigen levels.@*RESULTS@#On day 29, in the LY01005 and goserelin implant groups, testosterone concentrations fell below medical-castration levels in 99.3% (142/143) and 100% (140/140) of patients, respectively, with a difference of -0.7% (95% confidence interval [CI], -3.9% to 2.0%) between the two groups. The cumulative probabilities of maintaining castration from days 29 to 85 were 99.3% and 97.8%, respectively, with a between-group difference of 1.5% (95% CI, -1.3% to 4.4%). Both results met the criterion for non-inferiority. Secondary endpoints were similar between groups. Both treatments were well-tolerated. LY01005 was associated with fewer injection-site reactions than the goserelin implant (0% vs . 1.4% [2/145]).@*CONCLUSION@#LY01005 is as effective as goserelin implants in reducing testosterone to castration levels, with a similar safety profile.@*TRIAL REGISTRATION@#ClinicalTrials.gov, NCT04563936.

Switching of hormone therapies in breast cancer women / Avaliação da mudança do esquema hormonioterápico em mulheres com câncer de mama

Abstract Objective The objective of the present study was to analyze the reasons that led to hormone therapies (HTs) regimen changes in women with breast cancer. Methods This was a retrospective cross-sectional study from a single-institution Brazilian cancer center with patient records diagnosed with breast cancer between January 2012 and January 2017. Results From 1,555 women who were in treatment with HT, 213 (13.7%) women had HT switched, either tamoxifen to anastrozole or vice-versa. Most women included in the present study who switched HT were > 50 years old, postmenopausal, Caucasian, and had at least one comorbidity. From the group with therapy change, 'disease progression' was reason of change in 124 (58.2%) cases, and in 65 (30.5%) patients, 'presence of side effects' was the reason. From those women who suffered with side effects, 24 (36.9%) had comorbidities. Conclusion The present study demonstrated a low rate of HT switch of tamoxifen to anastrozole. Among the reasons for changing therapy, the most common was disease progression, which includes cancer recurrence, metastasis or increased tumor. Side effects were second; furthermore, age and comorbidities are risk factors for side effects.

Resumo Objetivo O objetivo do presente estudo foi analisar os motivos que levaram às mudanças no esquema hormonioterápico (HT) em mulheres com câncer de mama. Métodos Estudo transversal retrospectivo realizado no Hospital da Mulher de Campinas e consequente pesquisa de prontuários de mulheres diagnosticados com câncer de mama entre janeiro de 2012 e janeiro de 2017. Resultados De 1.555 mulheres em tratamento com HT, 213 (13,7%) mulheres tiveram HT alterado, tamoxifeno para anastrozol ou vice-versa. A maioria das mulheres incluídas no presente estudo que tiveram mudança de HT tinha > 50 anos, estava na pós-menopausa, era caucasiana e tinha pelo menos uma comorbidade. Os principais motivos de troca de HT foram devido a 'progressão da doença', ocorrendo em 124 (58,2%) casos e a 'presença de efeitos colaterais' (n = 65; 30,5%). Das mulheres que sofreram efeitos colaterais, 24 (36,9%) apresentaram comorbidades. Conclusão O presente estudo demonstrou uma baixa taxa na alteração de tamoxifeno para anastrozol. Entre as razõesmais comuns para alterar a HT estava a progressão da doença, que inclui recorrência do câncer, metástase ou aumento do tumor. Os efeitos colaterais foram a segunda causa e, além disso, a idade e as comorbidades foram fatores de risco para efeitos colaterais.

Urinary incontinence and overactive bladder symptoms in women with breast cancer being treated with oral hormone therapy / Incontinência urinária e sintomas de bexiga hiperativa em mulheres com câncer de mama em tratamento com terapia hormonal oral

Abstract Objective: The objective of the present study is to observe the frequency and severity of urinary symptoms in women with breast cancer (BC) being treated with oral hormone therapy, associating them to drug adherence. Methods: The participants were interviewed once from June to October 2016. The evaluation of urinary symptoms was performed by two questionnaires: International Consultation on Incontinence Questionnaire - Short Form (ICIQ-SF) and International Consultation on Incontinence Questionnaire Overactive Bladder Module (ICIQ-OAB). Adherence was evaluated by the Morisky-Green method. Statistical analysis was performed by the Mann-Whitney test, linear regression, and Spearman correlation. Results: Fifty-eight women were interviewed: 42 treated with tamoxifen and 16 with aromatase inhibitor. Twenty-seven women (46.5%) presented urinary incontinence symptoms and 15 (25.8%) presented stress urinary incontinence (SUI). Fourteen (24.1%) women had symptoms of overactive bladder (OAB). There was no statistical difference in symptoms between both treatments and duration of treatments. Higher scores in the ICIQ-SF questionnaire were associated with low/medium adherence and advanced age. Higher scores in the ICIQ-OAB questionnaire were associated with low/medium adherence. Conclusion: The present study showed a high prevalence of urinary symptoms, such as urinary incontinence and OAB, associated with low/medium adherence and older age in women with BC being treated with oral hormone therapy. Health professionals should be alert to these symptoms since it could influence life quality and adherence to treatment.

Resumo Objetivo: O objetivo do presente estudo foi observar a frequência e a gravidade dos sintomas urinários em mulheres com câncer de mama em uso de terapia hormonal oral, associando estes com a adesão ao tratamento. Métodos: As pacientes foram entrevistadas uma única vez, entre junho e outubro de 2016. A avaliação dos sintomas urinários foi realizada por dois questionários: International Consultation on Incontinence Questionnaire - Short Form (ICIQ-SF, na sigla em inglês) e o Questionário Sobre Bexiga Hiperativa (ICIQ-OAB, na sigla em inglês). A adesão foi avaliada pelo método Morisky-Green. A análise estatística foi realizada pelo teste de Mann-Whitney, regressão linear e correlação de Spearman. Resultados: Foram entrevistadas 58 mulheres: 42 tratadas com tamoxifeno e 16 com inibidor de aromatase. Vinte e sete mulheres (46,5%) apresentaram sintomas de incontinência urinária (IU) e 15 (25,8%) apresentaram incontinência urinária por estresse (IUS). Quatorze (24,1%) das mulheres tinham sintomas de bexiga hiperativa. Não houve diferença estatística nos sintomas entre os tratamentos e a duração dos tratamentos. Os escores mais elevados no questionário ICIQ-SF estiveram associados à baixa/média adesão e à idade avançada. Os escores mais elevados no questionário da ICIQ-OAB foram associados à baixa/média adesão. Conclusão: O presente estudo mostrou alta prevalência de sintomas urinários, como IU e bexiga hiperativa, associadas à baixa/média adesão e à idade mais avançada em mulheres com câncer de mama em tratamento com hormonioterapia oral. Os profissionais de saúde devem estar atentos a esses sintomas, pois eles podem influenciar a qualidade de vida e a adesão ao tratamento.

Use of GnRH analogues in the reduction of submucous fibroid for surgical hysteroscopy: A systematic review and meta-analysis / Uso de análogo de GnRH na redução de mioma submucoso na histeroscopia cirúrgica: Revisão sistemática e meta-análise

Abstract Objective Gonadotropin-releasing hormone analogues (GnRH-a) have been used preoperatively before hysteroscopic myomectomy to decrease the size and vascularization of the myomas, but evidence to support this practice is weak. Our objective was to analyze the use of GnRH-a in the reduction of submucous fibroid as a facilitator for surgical hysteroscopy from published clinical trials. Data sources Studies from electronic databases (Pubmed, Scielo, EMBASE, Scopus, PROSPERO), published between 1980 and December 2018. The keywords used were fibroid, GnRH analogue, submucous, histeroscopy, histeroscopic resection and their correspondents in Portuguese. Study selection The inclusion criteria were controlled trials that evaluated the GnRH-a treatment before hysteroscopic resection of submucous myomas. Four clinical trials were included in the meta-analysis. Data collection Two review authors extracted the data without modification of the original data, using the agreed form. We resolved discrepancies through discussion or, if required, we consulted a third person. Data synthesis The present meta-analysis included a total of 213 women and showed no statistically significant differences in the use of GnRH-a compared with the control group for complete resection of submucous myoma (relative risk [RR]: 0.94; 95%; confidence interval [CI]: 0.80-1.11); operative time (mean difference [MD]: - 3.81; 95%;CI : - 3.81-2.13); fluid absorption (MD: - 65.90; 95%;CI: - 9.75-2.13); or complications (RR 0.92; 95%;CI: 0.18-4.82). Conclusion The present review did not support the routine preoperative use of GnRH-a prior to hysteroscopic myomectomy. However, it is not possible to determine its inferiority when compared with the other methods due to the heterogeneity of existing studies and the small sample size.

Resumo Objetivo Análogos de hormônio liberador de gonadotrofina (GnRH-a) têm sido usados no pré-operatório de miomectomia histeroscópica para reduzir o tamanho e vascularização dos miomas, mas a evidência que suporta essa prática é fraca. Nosso objetivo foi analisar o uso de GnRH-a na redução do mioma submucoso como um facilitador de histeroscopia cirúrgica em ensaios clínicos publicados. Fonte de dados Estudos de bases de dados eletrônicas (Pubmed, Scielo, EMBASE, Scopus, PROSPERO), publicados entre 1980 e dezembro de 2018. As palavras-chave usadas foram fibroid, GnRH analogue, submucous, histeroscopy, histeroscopic resection e seus correspondentes em português. Seleção dos estudos Os critérios de inclusão foram ensaios clínicos controlados que avaliaram o tratamento com GnRH-a antes da ressecção histeroscópica de miomas submucosos. Quatro ensaios clínicos foram incluídos na meta-análise Coleta de dados Dois autores revisores extraíram os dados, sem modificarem os dados originais, usando a forma acordada. Nós resolvemos as discrepâncias através de discussão ou, se necessário, consultando um terceiro autor. Síntese dos dados A meta-análise incluiu um total de 213 mulheres e não demonstrou diferença estatisticamente significativa no uso de GnRH-a comparado com o grupo controle para ressecção completa de mioma submucoso (risco relativo [RR]: 0.94. índice de confiança [IC] 95%;: 0.80-1.11); tempo cirúrgico (diferença de média [MD]: - 3.81; IC95%;: -3.81-2.13); absorção de fluidos (MD: - 65.90; IC95%;: - 9.75-2.13); ou complicações (RR 0.92; IC95%;: 0.18-4.82). Conclusão A presente revisão sistemática não suporta o uso pré-operatório rotineiro de GnRH-a antes de miomectomia histeroscópica. No entanto, não é possível determinar sua inferioridade quando comparado aos outros métodos devido à heterogeneidade dos estudos existentes e ao pequeno tamanho da amostra.

Efficacy of Leuprorelide acetate (Eligard®) in daily practice in Brazil: a retrospective study with depot formulations in patients with prostate cancer

ABSTRACT Introduction: Androgen deprivation therapy (ADT) is the mainstay of therapy for advanced prostate cancer. Studies addressing the efficacy of different depot formulations of long acting luteinizing hormone releasing hormone agonists in the Brazilian population are lacking. We aimed to compare the efficacy of three schedules of leuprolide acetate in lowering PSA in a real world population. Materials and Methods: We reviewed the medical records of patients with prostate cancer seen at our institution between January 2007 and July 2018. We analyzed patients treated with long-acting leuprolide acetate and grouped these patients into three strata according to the administration of ADT every 1, 3 or 6 months. The primary outcome was the serum prostate specific antigen (PSA) levels at 6 and 12 months after treatment initiation. We used Friedman test to compare the distribution of PSA levels at baseline and at 6 and 12 months within each treatment stratum. We considered two-sided P values <0.05 as statistically significant. We analyzed toxicity descriptively. Results: We analyzed a total of 932 patients, with a median age of 72 years and a median time since diagnosis of prostate cancer of 8.5 months. ADT was administered monthly in 115 patients, quarterly in 637, and semiannually in 180. Nearly half of the patients had locally advanced disease. In comparison with baseline, median serum PSA levels were reduced at 12 months by at least 99.7% in the three strata (P <0.001 in all cases). Sexual impotence and hot flashes were the most frequently reported toxicities. Conclusion: To our knowledge, this is the largest assessment of real-world data on alternative schedules of leuprolide in a Brazilian population. Our study suggests that PSA levels can be effectively be reduced in most patients treated with monthly, quarterly, or semiannual injections of long-acting leuprolide acetate.

Cost-effectiveness analysis of abiraterone, docetaxel or placebo plus androgen deprivation therapy for hormone-sensitive advanced prostate cancer / Análise de custo-efetividade da adição de abiraterona ou quimioterapia ao tratamento do câncer de próstata metastático hormônio-sensível

ABSTRACT Objective To evaluate the cost-effectiveness of the addition of chemotherapy or abiraterone to androgen deprivation. Methods We developed an analytical model to determine the cost-effectiveness of the addition of docetaxel or abiraterone versus androgen deprivation therapy alone. Direct and indirect costs were included in the model. The effects were expressed in Quality-Adjusted Life Years adjusted for side effects. Results Compared to androgen deprivation therapy alone, the addition of chemotherapy and of abiraterone generated 0.492 and 0.999, respectively, in Quality-Adjusted Life Years. Abiraterone led to a Quality-Adjusted Life Years gain of 0.506 compared to docetaxel. The incremental costs per Quality-Adjusted Life Years were R$ 133.649,22 for docetaxel, R$ 330.828,70 for abiraterone and R$ 571.379,42 for abiraterone compared to docetaxel, respectively. Conclusion The addition of chemotherapy to androgen deprivation therapy is more cost-effective than the addition of abiraterone to androgen deprivation therapy. However, discounts on abiraterone cost might improve cost-effectiveness.

Métodos Um modelo analítico foi desenvolvido para determinar a relação custo-efetividade da adição de docetaxel ou abiraterona comparada à terapia de privação hormonal isolada. Custos diretos e indiretos foram incluídos no modelo. Os efeitos foram expressos em Anos de Vida Ajustados para Qualidade corrigidos pelos efeitos colaterais de cada terapia. Resultados A adição de quimioterapia e de abiraterona à terapia de privação hormonal aumentou os Anos de Vida Ajustados para Qualidade em 0,492 e 0,999, respectivamente, em comparação à terapia de privação hormonal isolada. A abiraterona promoveu ganho de Anos de Vida Ajustados para Qualidade de 0,506 em relação ao docetaxel. O custo incremental por Anos de Vida Ajustados para Qualidade foi R$ 133.649,22 para o docetaxel, R$ 330.828,70 para a abiraterona e R$ 571.379,42 para a abiraterona comparada ao docetaxel. Conclusão A adição de quimioterapia à terapia de privação hormonal é mais custo-efetiva que a adição de abiraterona à terapia de privação hormonal. Contudo, descontos no custo da abiraterona poderiam tornar esse tratamento mais custo-efetivo.

The current status of hormone treatment for prostate cancer patients in Korean real-world practice: a multi-institutional observational study / 亚洲男科学杂志(英文版)

We aimed to evaluate the current nationwide trend, efficacy, safety, and quality of life (QoL) profiles of hormone treatment in real-world practice settings for prostate cancer (PCa) patients in Korea. A total of 292 men with any biopsy-proven PCa (TanyNanyMany) from 12 institutions in Korea were included in this multi-institutional, observational study of prospectively collected data. All luteinizing hormone-releasing hormone (LHRH) agonists were allowed to be investigational drugs. Efficacy was defined as (1) the rate of castration (serum testosterone ≤50 ng dl-1) at 4-week visit and (2) breakthrough (serum testosterone >50 ng dl-1 after castration). Safety assessments included routine examinations for potential adverse events, laboratory tests, blood pressure, body weight, and bone mineral density (BMD, at baseline and at the last follow-up visit). QoL was assessed using the Expanded Prostate Cancer Index Composite-26 (EPIC-26). The most common initial therapeutic regimen was LHRH agonist with anti-androgen (78.0%), and the most commonly used LHRH agonist for combination and monotherapy was leuprolide (64.0% for combination and 58.0% for monotherapy). The castration and breakthrough rates were 78.4% and 6.6%, respectively. The laboratory results related to dyslipidemia worsened after 4 weeks of hormone treatment. In addition, the mean BMD T-score was significantly lower at the last follow-up (mean: -1.950) compared to baseline (mean: -0.195). The mean total EPIC-26 score decreased from 84.8 (standard deviation [s.d.]: 12.2) to 78.3 (s.d.: 8.1), with significant deterioration only in the urinary domain (mean: 23.5 at baseline and 21.9 at the 4-week visit). These findings demonstrate the nationwide trend of current practice settings in hormone treatment for PCa in Korea.

Clinical activity of abiraterone plus prednisone in docetaxel-naοve and docetaxel-resistant Chinese patients with metastatic castration-resistant prostate cancer / 亚洲男科学杂志(英文版)

This study investigated the clinical activity of abiraterone plus prednisone in docetaxel-naïve and docetaxel-resistant Chinese patients with metastatic castration-resistant prostate cancer (mCRPC). A total of 146 patients with docetaxel-naïve group (103 cases) and docetaxel-resistant group (43 cases) were enrolled from the Shanghai Cancer Center (Shanghai, China) in this retrospective cohort study. The efficacy endpoints were prostate-specific antigen response rate, prostate-specific antigen progression-free survival, clinical/radiographic progression-free survival, and overall survival in response to abiraterone plus prednisone. Significantly higher prostate-specific antigen response rate was found in docetaxel-naïve group (54.4%, 56/103) compared to docetaxel-resistant group (34.9%, 15/43) (P = 0.047). In addition, significantly higher median prostate-specific antigen progression-free survival (14.0 vs 7.7 months, P = 0.005), clinical or radiographic progression-free survival (17.0 vs 12.5 months, P = 0.003), and overall survival (27.0 vs 18.0 months, P = 0.016) were found in docetaxel-naïve group compared to docetaxel-resistant group, respectively. The univariate and multivariate analyses indicated that lower albumin and visceral metastases were independent significant predictors for shorter overall survival. To sum up, our data suggested that abiraterone plus prednisone was efficient in both docetaxel-naïve and docetaxel-resistant Chinese patients. Moreover, higher PSA response rate and longer overall survival were observed in the docetaxel-naïve group, which suggested that abiraterone was more effective for docetaxel- naïve patients than for docetaxel failures.

Factors Influencing Distress in Premenopausal Patients with Breast Cancer Undergoing Endocrine Therapy / 임상간호연구

PURPOSE: The purpose of this study was to investigate relationships among menopausal symptoms, functional status, and distress and to identify factors influencing distress in premenopausal breast cancer patients who had been on endocrine therapy. METHODS: A descriptive correlational study was conducted. Data were collected using questionnaires from 140 patients with breast cancer undergoing endocrine therapy at a general hospital. Data were analyzed using descriptive statistics, t-test, ANOVA, Tukey HSD test, Pearson's correlation analysis and hierarchical regression analysis. RESULTS: The mean scores for menopausal symptom, functional status, and distress were 19.65±7.86, 2.67±0.33 and 3.69±2.19, respectively. The menopausal symptoms and distress were positively correlated (r=.76, p<.001). The menopausal symptoms and functional status (r=−.43, p<.001) and functional status and distress (r=−.31, p<.001) were negatively correlated. The most influential factor for distress was menopausal symptoms (β=.79, p<.001). CONCLUSION: Based on the findings of this study, developing nursing intervention programs focusing on decreasing menopausal symptoms and distress are recommended.

Impacts of cytochrome P450 2D6 (CYP2D6) genetic polymorphism in tamoxifen therapy for breast cancer impactos do polimorfismo genético do citocromo P450 2D6 (CYP2D6) na terapia com tamoxifeno para câncer de mama

Abstract Tamoxifen (TMX) is the main drug used both in pre and postmenopausal women as adjuvant treatment for hormone receptor-positive breast cancer. An important barrier to the use of TMXis the development ofdrug resistance causedby molecular processes related to genetic and epigenetic mechanisms, such as the actions of cytochrome P450 2D6 (CYP2D6) polymorphisms and of its metabolites. The present study aimed to review recent findings related to the impact of CYP2D6 polymorphisms and how they can affect the results of TMX in breast cancer treatment. The keywords CYP2D6, tamoxifen, and breast cancer were searched in the PubMed, Scopus, The Cochrane Library, Scielo, and Bireme databases. Studies related to other types of neoplasms or based on other isoenzymes from cytochrome P450, but not on CYP2D6, were excluded. The impact of CYP2D6 polymorphisms in the TMX resistance mechanism remains unclear. The CYP2D6 gene seems to contribute to decreasing the efficacy of TMX, while the main mechanism responsible for therapy failure, morbidity, and mortality is the progression of the disease.

As palavras-chave CYP2D6, tamoxifeno e câncer de mama foram buscadas nas bases de dados Pubmed, Scopus, The Cochrane Library, Scielo e Bireme. Estudos relacionados com outros tipos de câncer ou relacionados a outras isoenzimas do citocromo P450 que não o CYP2D6 foram excluídos. O impacto do polimorfismo do CYP2D6 nos mecanismos de resistência ao tamoxifeno permanecem controversos. O gene CYP2D6 parece reduzir a eficácia do TMX; entretanto, os principais fatores associados a falha terapêutica são morbimortalidade e a progressão da doença

Miocardiopatia não compactada em gestante com linfoma não Hodgkin. Relato de caso / Non-compaction cardiomyopathy in pregnant women with non-Hodgkin lymphoma: a case report

A miocardiopatia não compactada é uma doença congênita rara, que pode ocorrer isoladamente ou associada a outros defeitos, por falha no processo de compactação das fibras miocárdicas, resultando na persistência de trabeculações e recessos profundos. A associação entre a miocardiopatia não compactada e gestação é incomum na literatura, assim como a relação com macroglobulinemia de Waldenstrom, um tipo de linfoma não Hodgkin. Descrevemos aqui a rara associação destas três patologias. Trata-se de paciente do sexo feminino, sem antecedentes hematológicos, neoplasias ou cardiopatias, que procurou o serviço com queixa de astenia progressiva, dores no corpo, perda ponderal importante e anemia. Na investigação diagnóstica, a imunoeletroforese de proteína constatou pico monoclonal em IgM Kappa, com inventário medular por imunofenotipagem e biópsia de medula óssea com Kappa+, CD19+, CD20+, CD38 e CD79b, confirmando diagnóstico de neoplasia de linfócitos B maduros. Na terapêutica, optou-se pelo esquema de primeira linha com dexametasona, rituximabe e ciclofosfamida (DRC) − este último considerado agente alquilante cardiotóxico. Em triagem pré-quimioterápica, o eletrocardiograma mostrou alteração da repolarização ventricular anterosseptal. O ecocardiograma transtorácico evidenciou trabeculações excessivas no ápice do ventrículo esquerdo, sugerindo não compactação do miocárdio. A ressonância magnética confirmou o diagnóstico. Foi iniciada terapia com metoprolol e ácido acetilsalisílico. Todavia, após o último ciclo de terapia quimioterápica, paciente descobriu gravidez (G1P1A0). O período gestacional e o puerpério evoluíram sem manifestações clínicas de insuficiência cardíaca, em classe funcional I (New York Heart Association), mesmo com redução da fração de ejeção do ventrículo esquerdo ao ecocardiograma transtorácico.

Non-compaction cardiomyopathy is a rare congenital disease that can occur in isolation or associated with other defects, due to failure in compaction of myocardial fiber, resulting in persistence of myocardial trabeculations and deep recesses. The association between non-compaction cardiomyopathy and gestation, as well as the relationship with Waldenstrom's macrobulinemia, a type of Non-Hodgkin's Lymphoma (NHL), are not common in the literature. This study describes the rare association of these three pathologies. This is the case of a female patient with no history of hematological, neoplastic, or heart diseases, who sought the service with complaints of progressive weakness, body aches, important weight loss, and anemia. During the diagnostic investigation, protein immunoelectrophoresis showed a monoclonal peak in IgM Kappa monoclonal gammopathy, with a medullary inventory by immunophenotyping and bone marrow biopsy with Kappa+, CD19+, CD20+, CD38 and CD79b, confirming the diagnosis of mature B-cell lymphocyte neoplasm. The first line therapy chosen was dexamethasone, rituximab, and cyclophosphamide (CKD), with the latter being considered a cardiotoxic alkylating agent. At pre-chemotherapy screening, the electrocardiogram showed an alteration of the anteroseptal ventricular repolarization. Transthoracic echocardiography (ETT) showed excessive trabeculations at the apex of the left ventricle (LV), suggesting no compaction of the myocardium. The magnetic resonance imaging confirmed the diagnosis.Therapy with metoprolol and acetylsalicylic acid was started. However, after the last cycle of chemotherapy, the patient found she was pregnant (G1P1A0). The gestational and puerperium period progressed with no clinical manifestations of heart failure, in functional class I (New York Heart Association), albeit the reduction of the ejection fraction of the left ventricular shown in the transthoracic echocardiography.

Leucemia linfoblástica aguda en niños con síndrome de Down: análisis comparativo con pacientes sin síndrome de Down / Acute lymphoblastic leukemia in children with Down syndrome: Comparative analysis versus patients without Down syndrome

Introducción: Los niños con síndrome de Down (SD) tienen mayor frecuencia de leucemia linfoblástica aguda (LLA) y menor supervivencia que pacientes sin síndrome de Down (NSD). Analizamos las características clínicas, demográficas-biológicas y respuestas al tratamiento en SD-LLA versus NSD-LLA. Pacientes y métodos: Pacientes (0-19 años) con LLA desde enero de 1990 a noviembre de 2016. Se compararon características demográficas biológicas y respuestas al tratamiento con chi cuadrado y Wilcoxon rank sum. La supervivencia global y el intervalo libre de eventos (ILE) se analizaron con Kaplan-Meier y el test log-rank. Resultados: Se incluyeron 1795 pacientes, 54 con SD. Los SD-LLA presentaron edad mayor (p= 0,0189). T odos inmuno fenotipo precursor-B, con menor incidencia de anomalías recurrentes (p < 0,0001). Demostraron mejor tasa de respuesta a prednisona (p= 0,09) y mayor mortalidad en inducción y remisión completa (p < 0,0001). Todas las muertes de los SD-LLA fueron relacionadas con el tratamiento. La sobrevida libre de eventos en niños SD-LLA vs.NSD-LLA fue 47 (± 8)% vs. 73 (± 1)% (p= 0,006) y el ILE de los SD-LLA vs. NSD-LLA fue 54 (± 9)% vs. 75 (± 1)% (p= 0,0297). La tasa de recaídas fue similar en ambos grupos (p= 0,6894). El ILE de los SD-LLA fue menor en el grupo de 6-9 años: 39 (± 19)% (p= 0,7885). Conclusiones: Los niños de 6-9 años con SD-LLA años presentó menor sobrevida. Aunque estos niños presentaron una mejor respuesta temprana, la sobrevida libre de eventos e ILE fueron menores debido a la mortalidad relacionada con el tratamiento.

Introduction. Children with Down syndrome (DS) more commonly have acute lymphoblastic leukemia (ALL) and a lower survival rate than those without Down syndrome (WDS). We analyzed the clinical, demographic, and biological characteristics and treatment response of children with DS-ALL versus those WDS-ALL. Patients and methods: Patients with ALL between January 1990 and November 2016. The demographic and biologic characteristics and treatment response were compared using the χ² and Wilcoxon rank-sum tests. The overall survival and event-free interval (EFI) were analyzed using the Kaplan-Meier and log-rank tests. Results. 1795 patients were included; 54 had DS. Patients with DS-ALL were older (p= 0.0189). All had B-cell precursor immunophenotype and a lower incidence of recurrent abnormalities (p < 0.0001). They showed a better response rate to prednisone (p= 0.09) and a higher mortality in induction and complete remission (p < 0.0001). All deaths of patients with DS-ALL were treatment-related. The event-free survival (EFS) was 47% (± 8%) versus 73% (± 1%) (p= 0.006) and the EFI was 54% (± 9%) versus 75% (± 1%) (p= 0.0297) among patients with DS-ALL versus those WDS-ALL, respectively. The rate of relapse was similar in both groups (p= 0.6894). The EFI of patients with DS-ALL was lower in the group aged 6-9 years: 39% (± 19%) (p= 0.7885). Conclusions. A lower survival was observed among children aged 6-9 years with DS-ALL. Although these children showed a better early response, their EFS and EFI were lower due to treatment-related mortality.

Antiplatelet Therapy in Breast Cancer Patients Using Hormonal Therapy: Myths, Evidence and Potentialities - Systematic Review / Terapia Antiplaquetária em Pacientes com Câncer de Mama em Uso de Terapia Hormonal: Mitos, Evidências e Potencialidades - Revisão Sistemática

Abstract Breast cancer is the most frequently diagnosed tumor in women worldwide, with a significant impact on morbidity and mortality. Chemotherapy and hormone therapy have significantly reduced mortality; however, the adverse effects are significant. Aspirin has been incorporated into clinical practice for over 100 years at a low cost, making it particularly attractive as a potential agent in breast cancer prevention and as an adjunct treatment to endocrine therapy in the prophylaxis of cardiovascular complications. The objective of this study was to evaluate the role of aspirin in reducing the incidence of breast cancer and to evaluate the impact of its use on morbidity and mortality and reduction of cardiovascular events as adjuvant therapy during breast cancer treatment with selective estrogen receptor modulators. A systematic review was performed using the PRISMA methodology and PICO criteria, based on the MEDLINE, EMBASE and LILACS databases. The original articles of clinical trials, cohort, case-control studies and meta-analyses published from January 1998 to June 2017, were considered. Most studies showed an association between the use of selective estrogen receptor modulators and the increase in thromboembolic events. The studies suggest a protective effect of aspirin for cardiovascular events during its concomitant use with selective estrogen receptor modulators and in the prevention of breast cancer. This systematic review suggests that aspirin therapy combines the benefit of protection against cardiovascular events with the potential reduction in breast cancer risk, and that the evaluation of the benefits of the interaction of endocrine therapy with aspirin should be further investigated.

Resumo O câncer de mama é o tumor mais frequentemente diagnosticado em mulheres de todo o mundo, com impacto importante na morbimortalidade. A quimioterapia e a terapia hormonal reduziram significativamente a mortalidade, mas os efeitos adversos são consideráveis. A aspirina está incorporada à prática clínica há mais de 100 anos, com baixo custo, tornando-a particularmente atraente como potencial agente na prevenção do câncer de mama e auxiliar durante o tratamento endócrino, na profilaxia de complicações cardiovasculares. Objetivou-se avaliar o papel da aspirina na redução da incidência do câncer de mama e avaliar o impacto de seu uso na morbimortalidade e na redução de eventos cardiovasculares como terapia adjuvante durante o tratamento do câncer de mama com moduladores seletivos do receptor do estrogênio. Procedeu-se à revisão sistemática utilizando-se a metodologia PRISMA e os critérios PICO, nas bases MEDLINE, EMBASE e LILACS. Foram considerados os artigos originais do tipo ensaio clínico, coorte, caso-controle e metanálises, publicados no período de janeiro de 1998 até junho de 2017. Na maioria dos estudos, houve relação entre o uso dos moduladores seletivos do receptor do estrogênio e o aumento de eventos tromboembólicos. Os estudos sugerem efeito protetor da aspirina para eventos cardiovasculares em uso concomitante aos moduladores seletivos do receptor do estrogênio e na prevenção do câncer de mama. Esta revisão sistemática sugere que o tratamento com aspirina combina o benefício da proteção contra eventos cardiovasculares com a potencial redução do risco de câncer de mama, e que a avaliação dos benefícios da interação da terapia endócrina com a aspirina deve ser melhor investigada.

Neuropatia periférica em pessoas com mieloma múltiplo / Neuropatía periférica en personas con mieloma múltiple / Peripheral neuropathy in people with multiple myeloma

Resumo Objetivo Investigar a prevalência e incidência de neuropatia periférica relacionada ao tratamento com antineoplásicos de pessoas com mieloma múltiplo bem como a associação entre os esquemas quimioterápicos e a neuropatia periférica após o tratamento. Método Estudo documental, correlacional, realizado em dois locais de referência para tratamento oncológico, localizados nos estados do Ceará e Minas Gerais, com análise de pacientes atendidos entre janeiro/2013 e janeiro/2016. Os dados foram analisados utilizando-se análise descritiva e inferencial a partir dos testes qui-quadrado e exato de fisher. Resultados Foram avaliados 100 prontuários de pessoas com mieloma múltiplo com média de idade de 62,7 anos, maioria de homens (64%). O esquema quimioterápico mais utilizado (60%) foi o bortezomibe, dexametasona e ciclofosfamida; 20% dos pacientes apresentavam neuropatia periférica antes do tratamento, 68% desenvolveram durante o tratamento e 56% ao finalizar o tratamento. Não houve associação entre os esquemas quimioterápicos e a neuropatia periférica após o tratamento. Conclusão O presente estudo mostrou um aumento da incidência de NP em indivíduos em tratamento para o MM, 80% apresentaram sintomas de neuropatia antes e/ou durante e/ou após o tratamento com esquemas quimioterápicos. A predominância foi de homens idosos aposentados. O esquema quimioterápico mais utilizado foi o VDC e não foi identificada associação entre os esquemas utilizados e a NP após término o tratamento. As implicações dessas observações recaem sobre a necessidade de avaliação contínua da NP em pessoas com MM, além da monitorização rigorosa desse evento no decorrer do tratamento e após o mesmo, bem como o manejo dos eventos adversos e alterações relacionadas a doença. Não houve associação entre os esquemas quimioterápicos e a neuropatia periférica após o tratamento. Espera-se que os resultados obtidos auxiliem na organização de um registro de dados sobre NP em pacientes com câncer, com o objetivo principal de determinar alvos de intervenção, tornando o cuidado mais eficiente e integral.

Abstract Objective To investigate the prevalence and incidence of peripheral neuropathy (PN) related to antineoplastic therapy in people with multiple myeloma and the association between chemotherapy regimens and peripheral neuropathy after treatment. Method This is a documentary and correlational study carried out in two reference sites for cancer treatment, located in the Brazilian states of Ceará and Minas Gerais, with an analysis of patients treated between January 2013 and January 2016. A descriptive and inferential analysis of data was carried out by means of chi-square and Fischer's exact tests. Results The study assessed 100 medical records of people with multiple myeloma, who were aged 62.7 years on average and were mostly men (64%). The most used chemotherapy regimen (60%) was bortezomib, dexamethasone, and cyclophosphamide; 20% of patients had peripheral neuropathy before treatment, 68% had it during treatment and 56% at the end of treatment. There was no association between chemotherapy regimens and peripheral neuropathy after treatment. Conclusion Our study showed an increase in the incidence of PN in individuals undergoing treatment of multiple myeloma, 80% had symptoms of neuropathy before and/or during and/or after treatment with chemotherapy regimens. Predominance was of elderly retired men. The most common chemotherapy regimen was bortezomib/dexamethasone/cyclophosphamide and there was no association between regimens used and PN after treatment. The implications of these observations rest on the need for a permanent assessment of PN in people with multiple myeloma, in addition to a strict follow-up to this event in the course of treatment and after it, as well as the management of adverse events and alterations related to the disease. There was no association between chemotherapy regimens and peripheral neuropathy after treatment. It is expected that the results obtained help in the organization of a data record about PN in patients with cancer, with the main purpose of establishing targets of intervention, thus making care more efficient and comprehensive.

Primary malignant tumors of the adrenal glands

Malignancy must be considered in the management of adrenal lesions, including those incidentally identified on imaging studies. Adrenocortical carcinomas (ACCs) are rare tumors with an estimated annual incidence of 0.7-2 cases per year and a worldwide prevalence of 4-12 cases per million/year. However, a much higher incidence of these tumors (>15 times) has been demonstrated in south and southeastern Brazil. Most ACCs cause hypersecretion of steroids including glucocorticoids and androgens. ACC patients have a very poor prognosis with a 5-year overall survival (OS) below 30% in most series. Pheochromocytoma or paraganglioma (PPGL) is a metabolically active tumor originating from the chromaffin cells of the adrenal medulla. The incidence of PPGL is 0.2 to 0.9 cases per 100,000 individuals per year. Pheochromocytomas are present in approximately 4-7% of patients with adrenal incidentalomas. Classically, PPGL manifests as paroxysmal attacks of the following 4 symptoms: headaches, diaphoresis, palpitations, and severe hypertensive episodes. The diagnosis of malignant PPGL relies on the presence of local invasion or metastasis. In this review, we present the clinical and biochemical characteristics and pathogenesis of malignant primary lesions that affect the cortex and medulla of human adrenal glands.
