ABSTRACT
Objective: To provide survival evidence of anthracycline-free neoadjuvant chemotherapy for patients with stages Ⅱ-Ⅲ human epidermal growth factor receptor-2 (HER-2) positive and hormone receptor (HR) negative breast cancer. Methods: The prospective cohort study was conducted at the Department of Medical Oncology of Cancer Hospital, Chinese Academy of Medical Sciences. Patients with HER-2 positive and HR negative breast cancer in stages Ⅱ-Ⅲ were enrolled to receive neoadjuvant therapy (NAT) of dose-dense paclitaxel (175 mg/m(2)) plus carboplatin (AUC=4.0) biweekly for 6 cycles in combination with trastuzumab (PCbH), and matched patients who received standard adjuvant therapy of physicians' choice were recruited for survival and safety comparison. Results: From July 2013 to November 2019, 166 patients were included (neoadjuvant 51, adjuvant 115). Compared with those who received adjuvant therapy, patients receiving NAT were younger (<35 years: 19.6% vs 5.2%, P=0.014), had larger tumors (T3: 62.7% vs 7.8%, P<0.001) and more advanced diseases (stage ⅡA: 2.0% vs 41.7%, P<0.001). Patients in the neoadjuvant group all received surgery, and 96 (83.5%) in the adjuvant group received anthracycline-and-taxane-containing regimens. A total of 98 patients (49 pairs) were matched, and the covariates between the two groups were acceptably balanced. Within a median follow-up of 46.5 (range, 14-87) months, the 4-year recurrence-free survival (RFS) rate among patients who received NAT was 73.3% (95% CI: 59.0%-87.6%), versus 80.6% (95% CI: 67.9%-93.3%) among those in the adjuvant group without statistical difference (P=0.418). A similar result was observed for the 4-year overall survival (OS) [neoadjuvant versus adjuvant: 91.5% (95% CI: 81.7%-100.0%) vs 97.8% (95% CI: 93.5%-100.0%), P=0.314]. Compared with standard adjuvant therapy, PCbH was related to less neutropenia and better cardiac safety. Conclusions: These results support the consideration of anthracycline-free neoadjuvant chemotherapy combined with anti-HER-2 therapy for patients with stages Ⅱ-Ⅲ HER-2-positive and HR-negative breast cancer. Optimized regimens with both efficacy and safety are needed and to be further investigated.

OBJECTIVES@#Nasopharyngeal cracinoma is a kind of head and neck malignant tumor with high incidence and high mortality. Due to the characteristics of local recurrence, distant metastasis, and drug resistance, the survival rate of patients after treatment is not high. Paclitaxel (PTX) is used as a chemotherapy drug in treating nasopharyngeal carcinoma, but nasopharyngeal carcinoma cells are easy to develop resistance to PTX. Inhibition of heat shock protein 90 (Hsp90) can overcome common signal redundancy and resistance in many cancers. This study aims to investigate the anti-tumor effect of ginkgolic acids C15꞉1 (C15:1) combined with PTX on nasopharyngeal carcinoma CNE-2Z cells and the mechanisms.@*METHODS@#This experiment was divided into a control group (without drug), a C15:1 group (10, 30, 50, 70 μmol/L), a PTX group (5, 10, 20, 40 nmol/L), and a combination group. CNE-2Z cells were treated with the corresponding drugs in each group. The proliferation of CNE-2Z cells was evaluated by methyl thiazolyl tetrazolium (MTT). Wound-healing assay and transwell chamber assay were used to determine the migration of CNE-2Z cells. Transwell chamber was applied to the impact of CNE-2Z cell invasion. Annexin V-FITC/PI staining was used to observe the effect on apoptosis of CNE-2Z cells. The changes of proteins involved in cell invasion, migration, and apoptosis after the combination of C15꞉1 and PTX treatment were analyzed by Western blotting.@*RESULTS@#Compared with the control group, the C15꞉1 group and the PTX group could inhibit the proliferation of CNE-2Z cells (all P<0.05). The cell survival rates of the C15꞉1 50 μmol/L combined with 5, 10, 20, or 40 nmol/L PTX group were lower than those of the single PTX group (all P<0.05), the combination index (CI) value was less than 1, suggesting that the combined treatment group had a synergistic effect. Compared with the 50 μmol/L C15꞉1 group and the 10 nmol/L PTX group, the combination group significantly inhibited the invasion and migration of CNE-2Z cells (all P<0.05). The results of Western blotting demonstrated that the combination group could significantly down-regulate Hsp90 client protein matrix metalloproteinase (MMP)-2 and MMP-9. The results of double staining showed that compared with the 50 μmol/L C15꞉1 group and the 10 nmol/L PTX group, the apoptosis ratio of CNE-2Z cells in the combination group was higher (both P<0.05). The results of Western blotting suggested that the combination group could decrease the Hsp90 client proteins [Akt and B-cell lymphoma-2 (Bcl-2)] and increase the Bcl-2-associated X protein (Bax).@*CONCLUSIONS@#The combination of C15꞉1 and PTX has a synergistic effect which can inhibit cell proliferation, invasion, and migration, and induce cell apoptosis. This effect may be related to the inhibition of Hsp90 activity by C15꞉1.

Objective: To evaluate the efficacy and survival outcomes of dose-dense (biweekly) carboplatin plus paclitaxel (PC) as neoadjuvant chemotherapy (NAC) in triple-negative breast cancer (TNBC), and to explore an optimal neoadjuvant chemotherapy regimen for TNBC. Methods: Patients diagnosed as TNBC(cT1-4N0-3M0) in Cancer Hospital, Chinese Academy of Medical Sciences & Peking Union Medical College Between January 2008 and September 2018 who received dose-dense PC and standard 3-weekly PC as NAC were 1∶1 matched using propensity score matching (PSM) to compare the efficacy, safety and survival outcomes. Results: One hundred of TNBC patients were enrolled (50 patients were divided in dose-dense group, 50 patients in standard group). The objective response rate (ORR) of dose-dense group and standard group were both 90.0% (45/50). The grade 3-4 neutropenia in dose-dense group was less than that of standard group (32.7% vs. 68.0%, P=0.001), while the rate of ALT/AST elevation in dose-dense group was higher than that of standard group (57.1% vs. 32.0%, P=0.012). The pathological complete response (pCR) rates were 34.0% (17/50) in dose-dense group and 38.0% (19/50) in standard group, without statistically significance (P=0.677). The median follow-up time was 55 months (3-150 months). The 5-year recurrence-free survival (RFS) in dose-dense group and standard group were 83.5% and 75.2%, respectively the 5-year overall survival (OS) in dose-dense and standard group were 87.9% and 84.5% the difference were not statistically significant (P=0.322 and 0.647, respectively). Patients with residual disease (tumor size≥1 cm or lymph node positive) had poor prognosis, the 5-year RFS and OS were 59.3% and 68.5%, respectively. Conclusions: Dose-dense PC has similar efficacy with standard 3-weekly PC and has a good safety profile. Since dose-dense regimen can shorten the duration of therapy, it can be an alternative in TNBC.

OBJECTIVE@#To investigate the effects of paclitaxel, quizartinib and their combination on proliferation, apoptosis and FLT3/STAT5 pathway of human leukemia cell line MV4-11 (FLT3-ITD+).@*METHODS@#MV4-11 cells were treated with paclitaxel and quizartinib at different concentrations for 24 h, 48 h and 72 h, respectively, and then the two drugs were combined at 48 h to compare the inhibition of proliferation, the apoptosis rate was detected by flow cytometry, the expression of FLT3 and STAT5 mRNA was determined by fluorescence quantitative PCR, and the protein expression of FLT3, p-FLT3, STAT5 and p-STAT5 was determined by Western blot.@*RESULTS@#Different combination groups of paclitaxel and quizartinib had synergistic inhibitory effect. The cell survival rate in the combination group was significantly lower than that in the single drug group (P<0.05). The cell apoptosis rate in the combination group was significantly higher than that in the single drug group (P<0.001). The expression of FLT3 mRNA in combination group was significantly higher than that in two single drugs (P<0.01). The expression of STAT5 mRNA in combination group was significantly higher than that in quizartinib group (P<0.001); increased compared with paclitaxel group, but there was no statistical significance. The expression level of p-FLT3、p-STAT5 protein in the combination group was significantly lower than that in the single drug group (P<0.05, P<0.05).@*CONCLUSION@#Paclitaxel combined with quizartinib can synergistically inhibit the proliferation of MV4-11 cell line and promote the apoptosis of MV4-11 cell line by inhibiting the activity of FLT3/STAT5 pathway.

Objective@#To investigate the molecular mechanism of high phosphorylation levels of cofilin-1 (p-CFL-1) associated with paclitaxel resistance in epithelial ovarian cancer (EOC) cells.@*Methods@#Cells displaying varying levels of p-CFL-1 and CFL-1 were created by plasmid transfection and shRNA interference. Cell inhibition rate indicating paclitaxel efficacy was assessed by Cell Counting Kit-8 (CCK-8) assay. Apoptosis was assessed by flow cytometry and protein levels were detected by western blotting. Quantitative real-time polymerase chain reaction (qRT-PCR) was used to measure the expression levels of phosphokinases and phosphatases of CFL-1. Survival analysis evaluated the correlation between the prognosis of EOC patients and the levels of p-CFL-1 and slingshot-1 (SSH-1).@*Results@#High levels of p-CFL-1 were observed in EOC cells that survived treatment with high doses of paclitaxel. SKOV3 cell mutants with upregulated p-CFL-1 showed impaired paclitaxel efficacy, as well as decreased apoptosis rates and pro-survival patterns of apoptosis-specific protein expression. Cytoplasmic accumulation of p-CFL-1 inhibited paclitaxel-induced mitochondrial apoptosis. SSH-1 silencing mediated CFL-1 phosphorylation in paclitaxel-resistant SKOV3 cells. Clinically, the high level of p-CFL-1 and the low level of SSH-1 in EOC tissues were closely related to chemotherapy resistance and poor prognosis in EOC patients.@*Conclusion@#The SSH-1/p-CFL-1 signaling pathway mediates paclitaxel resistance by apoptosis inhibition in EOC and is expected to be a potential prognostic predictor.

Introdução: Drogas antineoplásicas neurotóxicas estão frequentemente associadas à neuropatia periférica induzida por quimioterapia (NPIQ). Objetivo: Avaliar a evolução clínica dos pacientes expostos a tratamento antineoplásico potencialmente neurotóxico e identificar possíveis preditores clínicos e sociodemográficos para o desenvolvimento da NPIQ. Método: Estudo de coorte prospectiva com pacientes com diagnóstico de câncer de mama, ovário ou intestino em tratamento quimioterápico com paclitaxel, docetaxel ou oxaliplatina. Foram avaliados antes da quimioterapia (T1), no terceiro mês (T2) e 30-60 dias após interrupção do tratamento (T3). Todos responderam ao questionário de perfis sociodemográfico e clínico, foram avaliados por meio de exame clínico neurológico, pela escala de performance ECOG, escala hospitalar de ansiedade e depressão (HAD), escala de dor Short-cGuill, autorrelato de sintomas de NPIQ e avaliação com o questionário de neurotoxicidade induzida por antineoplásicos (CINQ). Resultados: Por meio de autorrelato, 75% da dos pacientes informaram apresentar sintomas de NPIQ. O CINQ evidenciou que 90% apresentaram algum grau de NPIQ em T2, enquanto 82,5% ainda persistiam em T3. Dor neuropática acometeu 42% da população (RR=1,429; IC95%=1,130-1,806). Os escores de ansiedade e depressão reduziram significativamente quando comparados ao início de tratamento (redução de 2,5 pontos na escala HAD, p<0,05). A capacidade funcional da população não mostrou alterações significativas. No T2, a escolaridade foi considerada preditora para autorrelato de sintomas de NPIQ (OR=1,314, IC95%=1,002-1,723, p=0,048). Conclusão:A baixa escolaridade pode comprometer a capacidade do paciente em relatar os sintomas da NPIQ. Este estudo chama a atenção para a necessidade de utilização de instrumentos específicos para detecção precoce da NPIQ.
Introduction: Neurotoxic antineoplastic drugs are frequently associated to chemotherapy-induced peripheral neuropathy (CIPN). Objective: To evaluate the clinical evolution of patients exposed to potentially neurotoxic antineoplastic treatment and to identify possible clinical and sociodemographic predictors for the development of CIPN. Method: Cohort prospective study with patients with breast, ovary or intestine diagnosis of cancer in chemotherapy treatment with paclitaxel, docetaxel or oxaliplatin. They were assessed before the chemotherapy (T1), in the third month (T2) and 30-60 days after the interruption of the treatment (T3). All the patients responded to the questionnaire of clinical and sociodemographic profiles, were evaluated through neurologic clinical exam, by the performance scale ECOG, by the Hospital Anxiety and Depression Scale - HAD, pain scale of Short-cGuill, self-report of symptoms of CIPN and evaluation with the questionnaire of antineoplastic-induced neurotoxicity (QAIN). Results: Through self-report, 75% of the patients presented symptoms of CIPN. The QAIN showed that 90% presented a certain degree of CIPN in T2, while 82.5% still persisted in T3. Neuropathic pain affected 42% of the population (RR = 1.429, CI95% = 1.130-1.806). Anxiety and depression scores significantly reduced when compared with the beginning of the treatment (reduction of 2.5 points in the scale HAD, p < 0.05). The functional capacity of the population did not show any significant change. The school level was considered a predictor of self-report of CIPN symptoms in T2 (OR = 1.314, CI95% = 1.002-1.723, p = 0.048). Conclusion: The low school level may taint the patient capacity to report CIPN symptoms. This study draws attention for the necessity to use specific instruments for early detection of CIPN.

Although Taxol has improved the survival of cancer patients as a first-line chemotherapeutic agent, an increasing number of patients develop resistance to Taxol after prolonged treatment. The potential mechanisms of cancer cell resistance to Taxol are not completely clear. It has been reported that microRNAs (miRNAs) are involved in regulating the sensitivity of cancer cells to various chemotherapeutic agents. In this study, we aimed to explore the role of miR-129-5p in regulating the sensitivity of breast cancer cells to Taxol. Cell apoptosis and autophagy, and the sensitivity of MCF-7 cells to Taxol were assessed with a series of in vitro assays. Our results showed that the inhibition of autophagy increased the Taxol-induced apoptosis and the sensitivity of MCF-7 cells to Taxol. Up-regulation of miR-129-5p also inhibited autophagy and induced apoptosis. Furthermore, miR-129-5p overexpression increased the sensitivity of MCF-7 cells to Taxol. High mobility group box 1 (HMGB1), a target gene of miR-129-5p and a regulator of autophagy, was negatively regulated by miR-129-5p. We found that interference of HMGB1 enhanced the chemosensitivity of Taxol by inhibiting autophagy and inducing apoptosis in MCF-7 cells. Taken together, our findings suggested that miR-129-5p increased the chemosensitivity of MCF-7 cells to Taxol through suppressing autophagy and enhancing apoptosis by inhibiting HMGB1. Using miR-129-5p/HMGB1/autophagy-based therapeutic strategies may be a potential treatment for overcoming Taxol resistance in breast cancer.

Summary Objective: The current study aimed to investigate the clinical efficacy of paclitaxel combined with avastin for non-small cell lung cancer (NSCLC) patients diagnosed with malignant pleural effusion (MPE). Method: Total of 33 patients diagnosed with NSCLC as well as malignant pleural effusion were included. All of them received paclitaxel (175 mg/m2) and avastin (5 mg/kg). Clinical efficacy was evaluated using the total response rate, overall survival, progression-free survival and changes in MPE volume. Adverse events and rates of toxicities were examined as well. Results: The total response rate reached 77% while the overall survival and the median progression-free survival were respectively 22.2 months and 8.4 months. Toxicities of grade 3-4 consisted of neutropenia in 57% of patients, anemia in 17% of them, febrile neutropenia in 11%, as well as anorexia in 7%. No treatment-correlated deaths were found. Conclusion: Paclitaxel combined with avastin decreased MPE volume and increased survival rate of NSCLC patients via inhibiting vascular endothelial growth factor expression.

A concomitância de doença arterial coronariana e câncer é uma apresentação frequente na prática da cardiologia. Além de compartilharem os mesmos fatores de risco para seu desenvolvimento e, portanto, os mesmos grupos demográficos, a toxicidade vascular da quimioterapia e da radioterapia torna mais alta a incidência da doença no grande grupo de sobreviventes do câncer. No ciclo do tratamento oncológico, a ocorrência de eventos cardíacos maiores, secundários ou não à cardiotoxicidade, é determinante de alteração ou interrupção de tratamento, com efeito importante na sobrevida. O objetivo da assistência especializada é retornar o paciente ao tratamento o mais precocemente possível e, na fase tardia, evitar a morte por doença cardiovascular. As peculiaridades da apresentação da doença coronariana e do diagnóstico e tratamento percutâneo são aqui discutidas
Concomitant coronary artery disease and cancer is a common presentation in current cardiovascular practice. Besides sharing the same risk factors for their development, and accordingly, the same demographic groups, vascular toxicity from chemotherapy and radiotherapy make the incidence of the disease higher in the large group of cancer survivors. During the cancer treatment cycle, the occurrence of major cardiac events, whether due to cardiotoxicity or not, is responsible for changes or interruption of treatment, with important effects on survival. The goal of specialized care is to return the patient to treatment as early as possible and in the later phase, to avoid death from cardiovascular disease. The specific characteristics of coronary disease and percutaneous diagnosis and treatment are discussed here

A evolução do tratamento oncológico resultou no desenvolvimento de fármacos altamente eficazes. No entanto, os efeitos colaterais da terapia antitumoral ainda são frequentes e, muitas vezes, limitantes. Entre os efeitos adversos possíveis, a cardiotoxicidade representa um grupo importante de manifestações, com impacto negativo a curto e longo prazo na evolução desses pacientes. Esses eventos podem ocorrer na ausência de fatores de risco de doença cardiovascular e sua evolução ainda não está totalmente esclarecida. Curiosamente, podem ser desencadeadas tanto por terapias sistêmicas convencionais quanto por novas terapias relacionadas com alvos moleculares específicos. As definições de cardiotoxicidade ainda são diversas e não há um consenso universal. Em linhas gerais, pode ser entendida como qualquer alteração da homeostase do sistema cardiovascular induzida pelo tratamento do câncer. O dano cardíaco pode apresentar-se por vasta gama de condições clínicas, como por exemplo, alterações metabólicas, hipertensão arterial sistêmica, síndromes coronarianas agudas, tromboembolismo arterial e venoso, arritmias, entre outros. Muitos destes eventos têm prognóstico pior que muitas neoplasias. Assim, o conhecimento dos efeitos adversos cardíacos do tratamento antineoplásico é de suma importância, e a avaliação cardiovascular do paciente com câncer é fundamental. O intuito desta revisão é apresentar de forma prática as drogas oncológicas com maior potencial cardiotóxico e discutir de forma resumida seus principais efeitos cardiovasculares. Serão discutidas brevemente as definições, os mecanismos de agressão cardíaca e as manifestações clínicas principais, além da evolução e manejo inicial
The evolution of oncological treatment has resulted in the development of highly effective drugs. However, the side effects of antineoplastic therapy are still frequent, and often limiting. Among the possible adverse effects, cardiotoxicity represents an important group of manifestations, with negative impact on the clinical development of these patients in the short and long terms. These events can occur in the absence of risk factors for cardiovascular disease, and their clinical course is still not fully clarified. Interestingly, they can be triggered by both conventional systemic therapies and by new therapies with specific molecular targets. There are several definitions of cardiotoxicity, and there is no universal consensus. In general terms, it can be understood as any modification of cardiovascular system homeostasis induced by cancer treatment. Cardiac damage can present as a wide range of clinical conditions, such as metabolic changes, systemic arterial hypertension, acute coronary syndromes, arterial and venous thromboembolism, and arrhythmias, among others. Many of these events have a worse prognosis than many neoplasms. Thus, the knowledge of the adverse cardiac effects of antineoplastic treatment is of paramount importance, and the cardiovascular evaluation of the cancer patient is essential. The purpose of this review is to offer a practical presentation of oncological drugs with greater cardiotoxic potential, and to summarize its main cardiovascular effects. The definitions, mechanisms of cardiac aggression, and main clinical manifestations will be briefly discussed, as well as the clinical course and initial management

Abstract Background: The place of drug-eluting balloons (DEB) in the treatment of in-stent restenosis (ISR) is not well-defined, particularly in a population of all-comers with acute coronary syndromes (ACS). Objective: Compare the clinical outcomes of DEB with second-generation drug-eluting stents (DES) for the treatment of ISR in a real-world population with a high proportion of ACS. Methods: A retrospective analysis of consecutive patients with ISR treated with a DEB compared to patients treated with a second-generation DES was performed. The primary endpoint was a composite of major adverse cardiovascular events (MACE: all-cause death, non-fatal myocardial infarction, and target lesion revascularization). Comparisons were performed using Cox proportional hazards multivariate adjustment and Kaplan-Meier analysis with log-rank. Results: The cohort included 91 patients treated with a DEB and 89 patients treated with a DES (74% ACS). Median follow-up was 26 months. MACE occurred in 33 patients (36%) in the DEB group, compared to 17 patients (19%) in the DES group (p log-rank = 0.02). After multivariate adjustment, there was no significant difference between the groups (HR for DEB = 1.45 [95%CI: 0.75-2.83]; p = 0.27). Mortality rates at 1 year were 11% with DEB, and 3% with DES (p = 0.04; adjusted HR = 2.85 [95%CI: 0.98-8.32]; p = 0.06). Conclusion: In a population with a high proportion of ACS, a non-significant numerical signal towards increased rates of MACE with DEB compared to second-generation DES for the treatment of ISR was observed, mainly driven by a higher mortality rate. An adequately-powered randomized controlled trial is necessary to confirm these findings.
Resumo Fundamento: O papel de balões farmacológicos (BFs) no tratamento de reestenose intra-stent (RIS) não está bem definido, particularmente em na síndrome coronária aguda (SCA). Objetivo: Comparar desfechos clínicos do uso de BF com stents farmacológicos (SFs) de segunda geração no tratamento de RIS em uma população real com alta prevalência de SCA. Métodos: Foi realizada uma análise retrospectiva de pacientes consecutivos com RIS tratados com um BF comparados a pacientes tratados com SF de segunda geração. O desfecho primário incluiu eventos cardiovasculares adversos importantes (morte por todas as causas, infarto do miocárdio não fatal, e revascularização da lesão alvo). As comparações foram realizadas pelo modelo proporcional de riscos de Cox ajustado e análise de Kaplan-Meier com log-rank. Resultados: A coorte incluiu 91 pacientes tratados com BF e 89 pacientes tratados com um SF (75% com SCA). O tempo mediano de acompanhamento foi de 26 meses. Eventos cardiovasculares adversos importantes ocorreram em 33 pacientes (36%) no grupo BF, e em 17 (19%) no grupo SF (p log-rank = 0,02). Após ajuste multivariado, não houve diferença significativa entre os grupos (HR para BF = 1,45 [IC95%: 0,75-2,83]; p = 0,27). As taxas de mortalidade de 1 ano foram 11% com BF, e 3% com SF (p = 0,04; HR ajustado = 2,85 [IC95%: 0,98-8,32; p = 0,06). Conclusão: Em uma população com alta prevalência de SCA, observou-se um aumento não significativo nas taxas de eventos cardiovasculares adversos importantes com o uso de BF comparado ao uso de SF de segunda geração para o tratamento de RIS, principalmente pelo aumento na taxa de mortalidade. É necessário um ensaio clínico controlado, randomizado, com poder estatístico adequado para confirmar esses achados.

Abstract Background Endovascular management of atherosclerotic infrainguinal arteries recently shifted towards drug eluting devices, designed to locally prevent the restenosis process. Numerous clinical studies report an advantage of drug coated balloons over uncoated balloon angioplasty in treating lower extremity peripheral artery disease. However, as coating and balloon platforms are different, each device requires dedicated clinical evaluations. Objective The aim of the study is to further investigate the safety and effectiveness of a Paclitaxel-Coated Balloon for the treatment of atherosclerotic infrainguinal arteries in a real-world setting. Methods 203 patients out of a final sample of 882 were enrolled in this prospective multicenter, observational, all-comers registry during the first 12 months. The primary endpoints were major adverse events (defined as procedure or device related death within 30 days post index procedure, clinically-driven target lesion revascularization or major target limb amputation) at 6 months and freedom from clinically-driven target lesion revascularization at 12 months. Both endpoints were adjudicated by a Clinical Events Committee. Results Mean patient age was 70.2±10.4 years (60.1% male). 47.3% of the patients were diabetic and 67.5% had a history of smoking. Severe claudication was reported in 37.4% and 40% had critical limb ischemia. 257 lesions, including 13.2% in the infrapopliteal territory, were treated with Passeo-18 Lux (mean lesion length 75.1 mm±69.4, 20% occlusions, 76.3% calcified). At 6 months, the rate of major adverse events was 5.5% (95%CI 3.1-9.7). Freedom from clinically-driven target lesion revascularization at 12 months was 93.2% (95%CI 89.1-95.8). All causes mortality was 6.5% (95%CI 3.8-11.0) and overall amputation rate was 4.2% (95%CI 2.1-8.3) at 12 months. Conclusion In a real-world environment, the BIOLUX P-III registry preliminary results confirm the safety and efficacy of the Paclitaxel-Coated Passeo-18 Lux balloon as a stand-alone treatment option for atherosclerotic infrainguinal arteries.
Resumo Contexto O manejo endovascular de artérias infrainguinais ateroscleróticas recentemente tem mudado para dispositivos farmacológicos, desenhados para impedir localmente o processo de reestenose. Numerosos estudos clínicos descrevem uma vantagem da angioplastia com uso de balões farmacológicos sobre os balões convencionais no tratamento de doença arterial periférica dos membros inferiores. No entanto, considerando que as plataformas do revestimento farmacológico e dos balões são diferentes, cada dispositivo requer avaliações clínicas específicas. Objetivo Fazer investigação adicional sobre a segurança e eficácia de um balão revestido com paclitaxel para o tratamento de artérias infrainguinais ateroscleróticas em um cenário de mundo real. Métodos 203 pacientes de uma amostra final de 882 pacientes foram incluídos neste registro prospectivo observacional multicêntrico de inclusão sequencial, durante os primeiros 12 meses. Os desfechos primários foram eventos adversos maiores (definidos como morte relacionada ao procedimento ou ao dispositivo em até 30 dias após o procedimento-índice, necessidade de revascularização da lesão-alvo ou amputação significativa do membro-alvo) em 6 meses e ausência de de revascularização da lesão-alvo em 12 meses. Ambos os desfechos foram adjudicados por um comitê de eventos clínicos. Resultados A idade média foi 70,2±10,4 anos (60,1% sexo masculino). 47,3% dos pacientes eram diabéticos, e 67,5% tinham história de tabagismo. Claudicação severa foi relatada em 37,4%, e 40% apresentava isquemia crítica de membro. 257 lesões, incluindo 13,2% em território infrapoplíteo, foram tratadas com o balão Passeo-18 Lux (comprimento médio das lesões 75,1 mm±69,4, 20% oclusões, 76,3% calcificadas). Aos 6 meses, a taxa de eventos adversos maiores foi de 5,5% (95%CI 3,1-9,7). A ausência de revascularização da lesão-alvo aos 12 meses foi de 93,2% (95%CI 89,1-95,8). Mortalidade por todas as causas foi de 6,5% (95%CI 3,8-11,0) e a taxa geral de amputação foi de 4,2% (95%CI 2,1-8,3) aos 12 meses. Conclusão Em um cenário de mundo real, os resultados preliminares do registro BIOLUX P-III confirmam a segurança e eficácia do balão revestido com paclitaxel Passeo-18 Lux como opção de tratamento único para artérias infrainguinais ateroscleróticas.

Resumo Contexto A reestenose intra-stent por hiperplasia miointimal pós-angioplastia é uma intercorrência frequente e que limita a perviedade do procedimento a longo prazo. A terapia com balões revestidos de droga com ação antiproliferativa pode ser uma alternativa no tratamento dessa complicação. Objetivos Demonstrar eficácia e as complicações (óbito, grandes amputações, etc.) do balão farmacológico no tratamento da reestenose intra-stent de segmento femoropoplíteo. Métodos Estudo de coorte retrospectivo de 32 pacientes consecutivos tratados entre os anos de 2012 e 2016, submetidos a terapia de reestenose intra-stent de segmento femoropoplíteo com angioplastia com balão farmacológico revestido com paclitaxel. A taxa de sucesso foi mensurada pela ocorrência de sucesso do procedimento e reestenose inferior a 50% em avaliação por eco-Doppler colorido 30, 90 e 180 dias após o procedimento. Resultados Quatro pacientes (12,5%) apresentaram reestenose superior a 50%, sendo um (3,1%) após 90 dias e três (9,4%) após 180 dias, conferindo uma taxa de sucesso de 87,5% ao procedimento. Após 180 dias, todos os pacientes referiam melhora ou cessação dos sinais e/ou sintomas apresentados antes do procedimento. Não houve óbitos, e complicações ocorreram apenas em dois casos, no pós-operatório imediato. Conclusões Os resultados a curto prazo da terapia com balão farmacológico são promissores, com redução na taxa de reestenose e baixo índice de complicações. Ainda precisam ser apresentados estudos demonstrando os efeitos a longo prazo dessa terapia, assim como seu impacto econômico quando comparada a outros procedimentos.
Abstract Background In-stent restenosis due to myointimal hyperplasia after angioplasty is common and limits long-term patency. Treatments using balloons coated with antiproliferative drugs may offer an alternative option for this pathology. Objectives To demonstrate the efficacy and complications (death, major amputations, etc.) of drug-coated balloons for treatment of in-stent restenosis in femoropopliteal segments. Methods This was a retrospective cohort study of 32 consecutive patients treated between 2012 and 2016 who underwent treatment to correct in-stent restenosis in the femoropopliteal segment using paclitaxel-coated balloons. The success rate was measured in terms of technical success and restenosis of less than 50% on Doppler ultrasonography at 30, 90, and 180 days after the procedure. Results Four patients (12.5%) exhibited restenosis greater than 50%, one (3.1%) after 90 days and three (9.4%) after 180 days, equating to a success rate of 87.5% of procedures, and by 180 days all patients experienced improvement or cessation of the signs and/or symptoms they had presented prior to the procedure. There were no deaths and complications occurred in just 2 cases in the immediate postoperative period. Conclusions Short-term results are promising, with reductions in the magnitude of restenosis and a low rate of complications. Further studies are needed that can demonstrate the long-term effects and the economic impacts in comparison to other procedures.

PURPOSE: This study compared the impact of paclitaxel-coated balloons (PCB) or drug eluting stents (DES) on peri-procedural myocardial infarction (PMI) on de novo coronary lesion in stable patients. MATERIALS AND METHODS: In this observational study, we compared the incidence of PMI amongst patients with single vessel de novo coronary lesions who underwent treatment with a PCB or DES. Propensity score-matching analysis was used to assemble a cohort of patients with similar baseline characteristics. PMI was classified as myocardial infarction occurring within 48 hours after percutaneous coronary intervention with a threshold of 5 x the 99th percentile upper reference limit of normal for creatine kinase-myocardial band (CK-MB) or troponin T (TnT). RESULTS: One hundred four patients (52 receiving PCB and 52 receiving DES) were enrolled in this study. The peak mean values of CK-MB and TnT were significantly higher in the DES group. There was a significantly higher rate of PMI in the DES group (23.1% vs. 1.9%, p=0.002). Total occlusion of the side-branch occurred in two patients treated with DES, while no patients treated with PCB. In multivariable analysis, DES was the only independent predictor of PMI compared with PCB (odds ratio 42.85, 95% confidence interval: 3.44–533.87, p=0.004). CONCLUSION: Treatment with a PCB on de novo coronary lesion might be associated with a significant reduction in the risk of PMI compared to DES.

OBJECTIVE: The toxicity of anti-cancer chemotherapeutic agents can be reduced by associating these compounds, such as the anti-proliferative agent paclitaxel, with a cholesterol-rich nanoemulsion (LDE) that mimics the lipid composition of low-density lipoprotein (LDL). When injected into circulation, the LDE concentrates the carried drugs in neoplastic tissues and atherosclerotic lesions. In rabbits, atherosclerotic lesion size was reduced by 65% following LDE-paclitaxel treatment. The current study aimed to test the effectiveness of LDE-paclitaxel on inpatients with aortic atherosclerosis. METHODS: This study tested a 175 mg/m2 body surface area dose of LDE-paclitaxel (intravenous administration, 3/3 weeks for 6 cycles) in patients with aortic atherosclerosis who were aged between 69 and 86 yrs. A control group of 9 untreated patients with aortic atherosclerosis (72-83 yrs) was also observed. RESULTS: The LDE-paclitaxel treatment elicited no important clinical or laboratory toxicities. Images were acquired via multiple detector computer tomography angiography (64-slice scanner) before treatment and at 1-2 months after treatment. The images showed that the mean plaque volume in the aortic artery wall was reduced in 4 of the 8 patients, while in 3 patients it remained unchanged and in one patient it increased. In the control group, images were acquired twice with an interval of 6-8 months. None of the patients in this group exhibited a reduction in plaque volume; in contrast, the plaque volume increased in three patients and remained stable in four patients. During the study period, one death unrelated to the treatment occurred in the LDE-paclitaxel group and one death occurred in the control group. CONCLUSION: Treatment with LDE-paclitaxel was tolerated by patients with cardiovascular disease and showed the potential to reduce atherosclerotic lesion size.

Objetivo: caracterizar a los pacientes oncológicos que presenten episodios de neutropenia febril postquimioterapia ingresados en el Instituto de Oncología y Radiobiología en el periodo de enero a mayo del 2015. Métodos: se realizó un estudio descriptivo de corte transversal a una muestra de 36 pacientes. Se revisaron las historias clínicas donde se tomaron las variables analizadas. Resultados: predominaron los pacientes del sexo femenino (61,1 por ciento). Dentro de las enfermedades oncológicas predominaron los pacientes con Linfomas no Hodgkin (25,0 por ciento) y los medicamentos citostáticos vinculados a la neutropenia fueron el carboplatino, paclitaxel, ifosfamida y etopósido. La recuperación hematológica se logró en la mayoría de los casos antes de las 72 horas y el mayor número de pacientes (72,2 por ciento) fueron clasificados como una neutropenia de bajo riesgo, según los criterios de la Multinational Association for Supportive Care. Conclusiones: en la muestra estudiada la neutropenia febril presenta un incremento proporcional con la edad y las enfermedades de origen hematopoyéticos, cuyos esquemas quimioterápicos consisten en altas dosis de agentes citostáticos(AU)
Objective: to characterize the oncological patients who present with post chemotherapy febrile neutropenia and were admitted to the Institute of Oncology and Radiobiology in the period of January to May, 2015. Methods: a descriptive cross-sectional study of a sample of 36 patients. Their medical histories were checked from which the analyzed variables were taken. Results: females predominated in the study (61,1 percent). Among the oncological diseases, non-Hodgkin lymphomas (25,0 percent) prevailed whereas the cytostatic drugs found related to neutropenia were carboplatin, paclitaxel, ifosfamide and etoposide. The hematological recovery was reached in most cases before 72 hours and a lot of patients (72, 2 percent) were classified as low risk neutropenia according to the Multinational Association for Supportive Care criteria. Conclusions: in the study sample, the febrile neutropenia increases with the age and with hematopoietic diseases whereas chemotherapy schemes are based on high dose cytostatic agents(AU)

A 50-year-old peri-menopausal woman presented with hard palpable mass on her lower abdomen and anemia from heavy menstrual bleeding. Ultrasonography showed a 13x12 cm sized hypoechoic solid mass in pelvis and a 2.5x2 cm hypoechoic cystic mass in uterine endometrium. Abdomino-pelvic computed tomography revealed a hypodense pelvic mass without enhancement, suggesting a leiomyoma of intraligamentary type or sex cord tumor of right ovary with submucosal myoma of uterus. Laparoscopy revealed a large Sertoli-Leydig cell tumor of right ovary with a very rare entity of intra-endometrial uterine leiomyoma accompanied by adenomyosis. The final diagnosis of ovarian sex-cord tumor (Sertoli-Leydig cell), stage Ia with intra-endometrial leiomyoma with adenomyosis, was made. Considering the large size of the tumor and poorly differentiated nature, 6 cycles of chemotherapy with Taxol and Carboplatin regimen were administered. There is neither evidence of major complications nor recurrence during 20 months' follow-up.

OBJETIVO: Analisar as desigualdades socioeconômicas na utilização de consultas médicas (CM) no último ano no Brasil. MÉTODOS: Dados da Pesquisa Nacional por Amostra de Domicílios (≥ 20 anos de idade) das Regiões Nordeste (2003, n = 75.652 e 2008, n = 79.779) e Sudeste (2003, n = 76.029 e 2008, n = 79.356) foram analisados segundo CM. Compararam-se as prevalências de CM segundo as variáveis exploratórias demográficas e de saúde no primeiro (D1) e último (D10) decil de renda familiar per capita. As análises consideraram o desenho amostral complexo. RESULTADOS: A proporção de pessoas com CM aumentou no período na Região Nordeste (61,2 para 66,9%) e Sudeste (67,9 para 73,5%). A diferença absoluta de CM, segundo D1 e D10 no período, foi de 6,4 pontos percentuais (pp) no Nordeste e 4,2 pp no Sudeste. Houve importante redução das desigualdades entre os homens; naqueles sem doenças crônicas; naqueles que tinham uma percepção positiva da sua saúde e naqueles sem plano de saúde com direito a CM. A Região Sudeste ainda apresentou redução entre aqueles com apenas uma morbidade autorreferida (8 pp) e com percepção negativa da saúde (6 pp). CONCLUSÃO: Houve aumento de CM no Brasil. Observa-se ainda persistente desigualdade entre os mais pobres e os mais ricos, maior no Nordeste do que no Sudeste. Políticas para a redução da desigualdade em saúde mais eficazes e equânimes devem ser adotadas no Brasil. .
OBJECTIVE: To analyze the socioeconomic inequalities in medical visits (MV) in the past year in Brazil. METHODS: Data from adults aged ≥ 20 years old who participated in the Brazilian National Household Surveys and living in the Northeastern (2003; n = 75,652 and 2008, n = 79,779) and Southeastern (2003; n = 76,029 and 2008; n = 79,356) regions were analyzed according to MV. We compared MVs according to demographic and health variables in the first (D1) and last (D10) per capita family income deciles. All analyses considered the complex cluster design. RESULTS: The proportion of people who had MV during this period increased in the Northeastern (from 61.2 to 66.9%) and the Southeastern (from 67.9 to 73.5%) regions. The absolute difference (AD) in the use of MV, according to D1 and D10 in this period, was equal to 6.4 percentage points (pp) in the Northeastern and 4.2 pp in the Southeastern regions. Significant reduction in inequalities was observed among men without chronic diseases, in those who had a positive perception of their health, and among those without health insurance which included MV. The Southeastern region has also showed significant reduction among those with chronic disease (8 pp) and with negative health self-perception (6 pp). CONCLUSION: The increasing number of MVs was found in Brazil. However, persistent inequalities were observed between the poorest and the richest, higher in the Northeastern than in the Southeastern region. More effective and equitable policies to reduce health inequalities should be adopted in Brazil. .
