Tisotumab Vedotin as Second- or Third-Line Therapy for Recurrent Cervical Cancer.

BACKGROUND: Recurrent cervical cancer is a life-threatening disease, with limited treatment options available when disease progression occurs after first-line combination therapy. METHODS: We conducted a phase 3, multinational, open-label trial of tisotumab vedotin as second- or third-line therapy in patients with recurrent or metastatic cervical cancer. Patients were randomly assigned, in a 1:1 ratio, to receive tisotumab vedotin monotherapy (2.0 mg per kilogram of body weight every 3 weeks) or the investigator's choice of chemotherapy (topotecan, vinorelbine, gemcitabine, irinotecan, or pemetrexed). The primary end point was overall survival. RESULTS: A total of 502 patients underwent randomization (253 were assigned to the tisotumab vedotin group and 249 to the chemotherapy group); the groups were similar with respect to demographic and disease characteristics. The median overall survival was significantly longer in the tisotumab vedotin group than in the chemotherapy group (11.5 months [95% confidence interval {CI}, 9.8 to 14.9] vs. 9.5 months [95% CI, 7.9 to 10.7]), results that represented a 30% lower risk of death with tisotumab vedotin than with chemotherapy (hazard ratio, 0.70; 95% CI, 0.54 to 0.89; two-sided P = 0.004). The median progression-free survival was 4.2 months (95% CI, 4.0 to 4.4) with tisotumab vedotin and 2.9 months (95% CI, 2.6 to 3.1) with chemotherapy (hazard ratio, 0.67; 95% CI, 0.54 to 0.82; two-sided P<0.001). The confirmed objective response rate was 17.8% in the tisotumab vedotin group and 5.2% in the chemotherapy group (odds ratio, 4.0; 95% CI, 2.1 to 7.6; two-sided P<0.001). A total of 98.4% of patients in the tisotumab vedotin group and 99.2% in the chemotherapy group had at least one adverse event that occurred during the treatment period (defined as the period from day 1 of dose 1 until 30 days after the last dose); grade 3 or greater events occurred in 52.0% and 62.3%, respectively. A total of 14.8% of patients stopped tisotumab vedotin treatment because of toxic effects. CONCLUSIONS: In patients with recurrent cervical cancer, second- or third-line treatment with tisotumab vedotin resulted in significantly greater efficacy than chemotherapy.

Extended Safety and Tolerability of Darolutamide for Nonmetastatic Castration-Resistant Prostate Cancer and Adverse Event Time Course in ARAMIS.

BACKGROUND: Patients with nonmetastatic castration-resistant prostate cancer (nmCRPC) are usually asymptomatic and seek treatments that improve survival but have a low risk of adverse events. Darolutamide, a structurally distinct androgen receptor inhibitor (ARi), significantly reduced the risk of metastasis and death versus placebo in ARAMIS. We assessed the extended safety and tolerability of darolutamide and the time-course profile of treatment-emergent adverse events (TEAEs) related to ARis and androgen-suppressive treatment. PATIENTS AND METHODS: Patients with nmCRPC were randomized 2:1 to darolutamide (n = 955) or placebo (n = 554). After trial unblinding, patients could receive open-label darolutamide. Tolerability and TEAEs were assessed every 16 weeks. Time interval-specific new and cumulative event rates were determined during the first 24 months of the double-blind period. RESULTS: Darolutamide remained well tolerated during the double-blind and open-label periods, with 98.8% of patients receiving the full planned dose. The incidence of TEAEs of interest in the darolutamide group was low and ≤2% different from that in the placebo group, except for fatigue. When incidences were adjusted for exposure time, there were minimal differences between the darolutamide double-blind and double-blind plus open-label periods. The rate of initial onset and cumulative incidence of grade 3/4 TEAEs and serious TEAEs were similar for darolutamide and placebo groups over 24 months. CONCLUSION: Extended treatment with darolutamide was well tolerated and no new safety signals were observed. Most ARi-associated and androgen-suppressive treatment-related TEAEs occurred at low incidences with darolutamide, were similar to placebo, and showed minimal increase over time with continued treatment. TRIAL NUMBER: ClinicalTrials.gov identifier NCT02200614.

Measuring cfDNA integrity as a biomarker for predicting neoadjuvant chemotherapy response in breast cancer patients: a pilot study.

PURPOSE: Circulating cell-free DNA (cfDNA) is a promising biomarker for predicting treatment response and disease outcomes in Breast Cancer (BC) patients undergoing neoadjuvant chemotherapy (NAC). To determine if cfDNA originates from tumors, matching tumor and cfDNA gene mutations are necessary, often requiring tumor DNA sequencing. We assessed plasma cfDNA integrity by measuring concentrations and ratios of larger-to-smaller Alu DNA fractions as a potential biomarker, eliminating the need for prior tumor sequencing. METHODS: We included patients with localized and/or locally advanced BC receiving standard NAC alone or in combination with immunotherapy and/or anti-HER2 targeted therapy. Blood samples were collected before treatment, every 2 weeks during treatment, and before surgery. RESULTS: Of the 38 evaluated patients, only 28 completed the protocol and underwent surgery after NAC. Seven patients (25%) achieved a pathologic complete response (pCR). We found that cfDNA integrity (cfDNAI) levels at 15 days after starting NAC were significantly higher in patients who achieved pCR (p = 0.045) and correlated significantly with Disease-Free Survival (DFS) in univariate analysis (p = 0.0371). CONCLUSIONS: Evaluation of cfDNAI 2 weeks after NAC initiation appears to be an early biomarker for tumor pCR and DFS. Measuring Alu fragments of different lengths may replace techniques requiring prior tumor sequencing to measure ctDNA, reducing costs and complexity of cfDNA serial measurements in BC patients undergoing NAC.

Prevalence of anticipatory nausea and vomiting in breast cancer patients undergoing highly emetogenic chemotherapy.

OBJECTIVE: Anticipatory nausea and vomiting are unpleasant symptoms observed before undergoing chemotherapy sessions. Less is known about the occurrence of symptoms since the advent of the new neurokinin-1 antagonist. METHODS: This prospective cohort study was performed at a single Brazilian Institution. This study included breast cancer patients who received doxorubicin and cyclophosphamide chemotherapy and an appropriate antiemetic regimen (dexamethasone 10 mg, palonosetron 0.56 mg, and netupitant 300 mg in the D1 followed by dexamethasone 10 mg 12/12 h in D2 and D4). Patients used a diary to record nausea, vomiting, and use of rescue medication in the first two cycles of treatment. The prevalence of anticipatory nausea and vomiting was assessed before chemotherapy on day 1 of C2. RESULTS: From August 4, 2020, to August 12, 2021, 60 patients were screened, and 52 patients were enrolled. The mean age was 50.8 (28-69) years, most had stage III (53.8%), and most received chemotherapy with curative intent (94%). During the first cycle, the frequency of overall nausea and vomiting was 67.31%, and that of severe nausea and vomiting (defined as grade>4 on a 10-point visual scale or use of rescue medication) was 55.77%. Ten patients had anticipatory nausea and vomiting (19.23%). The occurrence of nausea and vomiting during C1 was the only statistically significant predictor of anticipatory nausea and vomiting (OR=16, 95%CI 2.4-670.9, p=0.0003). CONCLUSION: The prevalence of anticipatory nausea is still high in the era of neurokinin-1 antagonists, and failure of antiemetic control in C1 remains the main risk factor. All efforts should be made to control chemotherapy-induced nausea or nausea and vomiting on C1 to avoid anticipatory nausea.

Giredestrant for Estrogen Receptor-Positive, HER2-Negative, Previously Treated Advanced Breast Cancer: Results From the Randomized, Phase II acelERA Breast Cancer Study.

PURPOSE: To compare giredestrant and physician's choice of endocrine monotherapy (PCET) for estrogen receptor-positive, HER2-negative, advanced breast cancer (BC) in the phase II acelERA BC study (ClinicalTrials.gov identifier: NCT04576455). METHODS: Post-/pre-/perimenopausal women, or men, age 18 years or older with measurable disease/evaluable bone lesions, whose disease progressed after 1-2 lines of systemic therapy (≤1 targeted, ≤1 chemotherapy regimen, prior fulvestrant allowed) were randomly assigned 1:1 to giredestrant (30 mg oral once daily) or fulvestrant/aromatase inhibitor per local guidelines (+luteinizing hormone-releasing hormone agonist in pre-/perimenopausal women, and men) until disease progression/unacceptable toxicity. Stratification was by visceral versus nonvisceral disease, prior cyclin-dependent kinase 4/6 inhibitor, and prior fulvestrant. The primary end point was investigator-assessed progression-free survival (INV-PFS). RESULTS: At clinical cutoff (February 18, 2022; median follow-up: 7.9 months; N = 303), the INV-PFS hazard ratio (HR) was 0.81 (95% CI, 0.60 to 1.10; P = .1757). In the prespecified secondary end point analysis of INV-PFS by ESR1 mutation (m) status in circulating tumor DNA-evaluable patients (n = 232), the HR in patients with a detectable ESR1m (n = 90) was 0.60 (95% CI, 0.35 to 1.03) versus 0.88 (95% CI, 0.54 to 1.42) in patients with no ESR1m detected (n = 142). Related grade 3-4 adverse events (AEs), serious AEs, and discontinuations due to AEs were balanced across arms. CONCLUSION: Although the acelERA BC study did not reach statistical significance for its primary INV-PFS end point, there was a consistent treatment effect with giredestrant across most key subgroups and a trend toward favorable benefit among patients with ESR1-mutated tumors. Giredestrant was well tolerated, with a safety profile comparable to PCET and consistent with known endocrine therapy risks. Overall, these data support the continued investigation of giredestrant in other studies.

Subcutaneous versus Intravenous Amivantamab, both in Combination with Lazertinib, in Refractory EGFR-mutated NSCLC: Primary Results from the Phase 3 PALOMA-3 Study.

PURPOSE: Phase 3 studies of intravenous amivantamab demonstrated efficacy across EGFR-mutated advanced non-small cell lung cancer (NSCLC). A subcutaneous formulation could improve tolerability and reduce administration time while maintaining efficacy. PATIENTS AND METHODS: Patients with EGFR-mutated advanced NSCLC who progressed following osimertinib and platinum-based chemotherapy were randomized 1:1 to receive subcutaneous or intravenous amivantamab, both combined with lazertinib. Co-primary pharmacokinetic noninferiority endpoints were trough concentrations (Ctrough; on cycle-2-day-1 or cycle-4-day-1) and cycle-2 area under the curve (AUCD1-D15). Key secondary endpoints were objective response rate (ORR) and progression-free survival (PFS). Overall survival (OS) was a predefined exploratory endpoint. RESULTS: Overall, 418 patients underwent randomization (subcutaneous group, n=206; intravenous group, n=212). Geometric mean ratios of Ctrough for subcutaneous to intravenous amivantamab were 1.15 (90% CI, 1.04-1.26) at cycle-2-day-1 and 1.42 (90% CI, 1.27-1.61) at cycle-4-day-1; the cycle-2 AUCD1-D15 was 1.03 (90% CI, 0.98-1.09). ORR was 30% in the subcutaneous and 33% in the intravenous group; median PFS was 6.1 and 4.3 months, respectively. OS was significantly longer in the subcutaneous versus intravenous group (hazard ratio for death, 0.62; 95% CI, 0.42-0.92; nominal P=0.02). Fewer patients in the subcutaneous group experienced infusion-related reactions (13% versus 66%) and venous thromboembolism (9% versus 14%) versus the intravenous group. Median administration time for first infusion was reduced to 4.8 minutes (range, 0-18) for subcutaneous amivantamab from 5 hours (range, 0.2-9.9) for intravenous amivantamab. During cycle-1-day-1, 85% and 52% of patients in the subcutaneous and intravenous groups, respectively, considered treatment convenient; end-of-treatment rates were 85% and 35%, respectively. CONCLUSION: Subcutaneous amivantamab-lazertinib demonstrated noninferiority to intravenous amivantamab-lazertinib, offering a consistent safety profile with reduced infusion-related reactions, increased convenience, and prolonged survival.

Role of intrathecal chemotherapy in the management of meningeal carcinomatosis in patients with breast cancer.

OBJECTIVE: To evaluate whether intrathecal chemotherapy improves clinical outcomes in patients with meningeal carcinomatosis. METHODS: This retrospective cohort study included consecutive patients with breast cancer diagnosed with meningeal carcinomatosis. Clinical and treatment data were collected from the patients' medical charts. The primary outcome was overall survival, and the secondary outcomes were time to neurological deterioration and reporting of clinical benefit. Logistic regression and Cox proportional hazard models adjusted for potential confounders were used to evaluate the clinical response and overall survival, respectively. RESULTS: Overall, 109 female patients were included, 50 (45.9%) of whom received intrathecal chemotherapy with methotrexate and dexamethasone. The median treatment duration was 3 weeks (range, 1-13 weeks). Patients treated with intrathecal chemotherapy were more likely to report clinical benefit (74% versus 57.7%, adjusted odds ratio [OR] = 9.0, 95%CI=2.6-30.9, p<0.001). However, there was no difference in the time to neurologic deterioration (hazard ratio [HR] = 0.96, 95%CI= 0.57-1.59, p=0.86). Patients who received intrathecal chemotherapy did not show an increase in overall survival compared with that of patients who did not receive intrathecal chemotherapy (median overall survival = 1.8 months, 95%CI= 1.27-3.0 versus 2.5, 95%CI= 1.9-3.9, adjusted HR = 0.71, 95%CI= 0.41-1.22, p=0.21). There was a significant interaction between intrathecal chemotherapy and systemic treatment, and patients who received systemic therapy without intrathecal chemotherapy had better overall survival than that of the no-treatment group (adjusted HR = 0.38, 95%CI= 0.20-0.70, p=0.002). CONCLUSION: Intrathecal chemotherapy did not increase overall survival or time to neurological deterioration and should not preclude or postpone systemic treatments.

Febrile neutropenia incidence and the variable toxicity profile between brand and generic docetaxel in the adjuvant treatment of breast cancer with docetaxel and cyclophosphamide regimen.

OBJECTIVE: To assess the incidence of febrile neutropenia without primary granulocyte colony-stimulating factor prophylaxis in patients undergoing chemotherapy with adjuvant docetaxel and cyclophosphamide, and to evaluate the toxicity profile of brand-name docetaxel (Taxotere ® ) and the generic formulation. METHODS: This retrospective study was conducted using data obtained from electronic medical records of patients treated at a Brazilian cancer center. Patients with breast cancer who underwent adjuvant treatment between January 2016 and June 2019 were selected. Data were analyzed using chi-square and Fisher correlation of variables, and multivariate analyses were adjusted for propensity score. RESULTS: A total of 231 patients with a mean age of 55.9 years at the time of treatment were included in the study. The majority (93.9%) had luminal histology, 84.8% were at clinical stage I, and 98.2% had a good performance status. The overall incidence of febrile neutropenia in the study population was 13.4% (31 cases). The use of brand-name docetaxel (Taxotere ® ) was the only factor associated with febrile neutropenia occurrence (OR= 3.55, 95%CI= 1.58-7.94, p=0.002). CONCLUSION: In patients with breast cancer who require treatment with adjuvant docetaxel and cyclophosphamide regimen, the toxicity profile differs between brand-name and generic docetaxel. Regardless of the formulation used, the incidence of febrile neutropenia was less than 20%, which may allow for the omission of primary prophylactic granulocyte colony-stimulating factor use in this setting.

Estudo de fase II de pregabalina para prevenção de náuseas e vômitos induzidos por quimioterapia / Phase II study of pregabalin for the prevention of chemotherapy induced nausea and vomiting

Para avaliar o papel da pregabalina na proteção das náuseas e vômitos induzidos pela quimioterapia, foi realizado um ensaio clínico de fase II, aleatorizado, duplamente cego, controlado por placebo, para investigar se a pregabalina poderia melhorar o controle completo das náuseas e vômitos (desfecho primário). Inscrevemos 82 pacientes virgens de quimioterapia, programados para receber quimioterapia moderadamente e altamente emetogênica. Todos os doentes receberam ondansetron 8mg por via intravenosa, dexametasona 10mg antes da quimioterapia no primeiro dia e, dexametasona 4 mg por via oral, b.d., nos dias dois e três. Os doentes foram distribuídos aleatoriamente para tomar pregabalina 75 mg ou placebo, bd, desde a noite anterior à quimioterapia até ao quinto dia. A resposta completa global não foi estatisticamente significativa entre os grupos (53,7 versus 48,8%, respetivamente, no grupo da pregabalina e no grupo de controlo (P=0,65)). Também não houve diferença estatística significativa durante a fase aguda (primeiras 24 horas) e a fase tardia (24-120h): 80,5% versus 82,9% (P=0,77), 53,7 versus 51,2% (P=0,82), respectivamente. Neste estudo não foi identificada ação da pregabalina na prevenção de náuseas e vômitos induzidos por quimioterapia. Número de registo no Clinicaltrial.gov: NCT04181346.

To evaluate the role of pregabalin in the protection of chemotherapy-induced nausea and vomiting, we performed a phase II randomized, double-blind, placebo-controlled trial to investigate whether pregabalin could improve the complete control of nausea and vomiting (primary end point). We enrolled 82 chemotherapy-naive patients, scheduled to receive moderately and highly emetogenic chemotherapy. All patients received IV ondansetron 8mg, dexamethasone 10mg before chemotherapy on day one and oral dexamethasone 4mg, b.d., on days two and three. Patients were randomly assigned to take pregabalin 75mg or placebo, bd, from the night before chemotherapy to day five. The overall complete response was not statistically significant between the groups (53.7 versus 48.8%, respectively, in the pregabalin group and the control group (P=0.65)). There was also no significant difference during the acute phase (first 24 hours) and delayed phase (24-120h): 80.5% versus 82.9% (P=0.77), 53.7 versus 51.2% (P=0.82), respectively. There is no role for pregabalin preventing chemotherapy-induced nausea and vomiting. Clinicaltrial.gov registration number: NCT04181346.

All efforts should be made to control chemotherapy-induced nausea or nausea and vomiting on C1 to avoid anticipatory nausea.

Prevalence and predisposing factors for fatigue in patients with chronic renal disease undergoing hemodialysis: a cross-sectional study

ABSTRACT BACKGROUND: Patients with chronic renal disease and undergoing hemodialysis are at a high risk for developing several complications. Fatigue is a common, troubling symptom that affects such patients and can contribute to unfavorable outcomes and high mortality. OBJECTIVE: This cross-sectional study aimed to evaluate the prevalence of fatigue in Brazilian patients with chronic kidney disease undergoing hemodialysis and determine the predisposing factors for fatigue. DESIGN AND SETTING: An observational, cross-sectional, descriptive study was conducted in two renal replacement therapy centers in the Greater ABC region of São Paulo. METHODS: This study included 95 patients undergoing dialysis who were consecutively treated at two Brazilian renal replacement therapy centers between September 2019 and February 2020. The Chalder questionnaire was used to evaluate fatigue. Clinical, sociodemographic, and laboratory data of the patients were recorded, and the Short Form 36 Health Survey, Pittsburgh Sleep Quality Index, and Beck Depression Inventory were administered. RESULTS: The prevalence of fatigue in patients undergoing hemodialysis was 51.6%. Fatigue was independently associated with lower quality of life in terms of physical and general health. Patients with fatigue had a higher incidence of depression (65.9% vs. 34.1%, P = 0.001) and worse sleep quality (59.1% vs. 49.9%; P = 0.027) than those without fatigue. CONCLUSION: Prevalence of fatigue is high in patients undergoing hemodialysis and is directly related to physical and general health.

High mortality among patients with cancer and COVID-19 infection: the experience of a Brazilian cancer center / Alta mortalidade entre pacientes com câncer e infecção por COVID-19: a experiência de um centro oncológico brasileiro

ABSTRACT Objective To evaluate the severity of COVID-19 in cancer patients to describe clinical and epidemiological factors associated with poor outcomes (mortality and need of intensive care unit admission or mechanical ventilation). Methods Retrospective data from patients with cancer and laboratory diagnosis of COVID-19, obtained between March 16 and May 29, 2020, were retrieved out of a cancer center database. Data analyzed included patient history, age, sex, comorbidities, types of cancer and anticancer therapy. Results This sample comprised 105 patients aged 18-92 years, 80.9% of whom were females. Dyspnea was the most prevalent initial symptom (30.4%) among patients who died (p<0.0001). Overall, 57.1% of patients had metastatic disease and 60% had poor performance status (Eastern Cooperative Oncologic Group ≥2) at the time of COVID-19 diagnosis. The overall mortality rate was 40.95%. Mortality rates were higher in male patients and those with poor performance status (p<0.0001). Conclusion This cohort is one of the largest Brazilian studies describing clinical and epidemiological features of patients with cancer and concurrent COVID-19. Findings of this study emphasize the vulnerability of cancer patients in the current pandemic, and indicate high mortality from COVID-19 among male cancer patients and cancer patients with poor performance status. This analysis may assist the selection of patients who may benefit from strict isolation and eventual discontinuation of anticancer therapy to reduce exposure to infection.

RESUMO Objetivo Avaliar a gravidade da infecção por COVID-19 em pacientes oncológicos, determinando os aspectos clínicos e epidemiológicos associados ao pior desfecho, seja em termos de mortalidade, necessidade de internação em unidade de terapia intensiva ou ventilação mecânica. Métodos Pacientes com câncer e diagnóstico confirmado por laboratório de COVID-19 foram identificados nos bancos de dados de um hospital oncológico entre 16 de março e 29 de maio de 2020. Os dados coletados incluíram história, idade, sexo e comorbidades dos pacientes, além dos tipos de câncer e do tratamento anticâncer. Resultados Dentre os 105 pacientes analisados, a idade variou de 18 a 92 anos, e 80,9% eram do sexo feminino. Dispneia foi o sintoma inicial mais prevalente entre os que morreram (30,4%). No momento do diagnóstico da infecção, 57,1% apresentavam doença metastática e 60% performance status ruim (Eastern Cooperative Oncologic Group ≥2). A taxa de mortalidade geral foi 40,95% e superior entre os homens e pacientes com baixo nível de performance status (p<0,0001). Conclusão Este coorte é um dos estudos mais robustos do Brasil, descrevendo características clínicas e epidemiológicas de pacientes com câncer e COVID-19. Os achados do estudo alertam para a vulnerabilidade dos pacientes oncológicos na pandemia atual e demonstram alta mortalidade por COVID-19 em pacientes do sexo masculino e com pior performance status. Essa análise pode ajudar a selecionar os pacientes que podem se beneficiar de isolamento rigoroso e até mesmo da interrupção do tratamento, reduzindo a exposição à infecção.

COVID-19 in the perioperative period of cardiovascular surgery: the brazilian experience

Abstract Introduction: We investigated the clinical course and outcomes of patients submitted to cardiovascular surgery in Brazil and who had developed symptoms/signs of coronavirus disease 2019 (COVID-19) in the perioperative period. Methods: A retrospective multicenter study including 104 patients who were allocated in three groups according to time of positive real time reverse transcriptase-polymerase chain reaction (RT-PCR) for the SARS-CoV-2 (severe acute respiratory syndrome coronavirus 2): group 1, patients who underwent cardiac surgery > 10 days after positive RT-PCR; group 2, patients with a positive RT-PCR within 10 days before or after surgery; group 3, patients who presented positive RT-PCR > 10 days after surgery. The primary outcome was mortality and secondary outcomes were postoperative complications, intensive care unit (ICU) length of stay, and postoperative days of hospitalization. Results: The three groups were similar with respect to age, the European System of Cardiac Operative Risk Evaluation score, and comorbidities, except hypertension. Postoperative complications and death were significantly higher in groups 2 and 3 than in group 1, and no significant difference between groups 2 and 3 was seen. Group 2 showed a high prevalence of surgery performed as an urgent procedure. Although no significant differences were observed in ICU length of stay, total postoperative hospitalization time was significantly higher in group 3 than in groups 1 and 2. Conclusion: COVID-19 affecting the postoperative period of patients who underwent cardiovascular surgery is associated with a higher rate of morbidity and mortality. Delaying procedures in RT-PCR-positive patients may help reduce risks of perioperative complications and death.

La cirugía en el tratamiento de la crisis tirotóxica / Surgery for the Treatment of Thyrotoxic Crisis

RESUMEN La crisis tirotóxica es una complicación de la tirotoxicosis mal tratada y se asocia con una elevada mortalidad. Requiere tratamiento médico urgente en unidades de cuidados intensivos. Mujer de 42 años, con antecedentes personales de hipertensión arterial y nódulo tiroideo hiperfuncionante desde hace 18 años, con abandono del tratamiento médico hace dos años, que acude a urgencias con disnea paroxística nocturna, taquicardia, hipertensión arterial, gran bocio y anasarca. Ingresa en la unidad de cuidados intensivos con diagnóstico de crisis tirotóxica e inicia el tratamiento médico con medidas de soporte precisas, la que incluye intubación orotraqueal. Debido a la dificultad de manejo clínico y respiratorio de la paciente, se decide realizar tratamiento quirúrgico urgente. Se practica una tiroidectomía total de bocio multinodular parcialmente intratorácico y una traqueostomía preventiva. El resultado de anatomía patológica fue: bocio multinodular tóxico. La paciente fue dada de alta con función tiroidea normal, cierre de traqueostomía y buena fonación, tras mes y medio de hospitalización. A pesar de que un tratamiento médico conservador es el adecuado de la tirotoxicosis, los síntomas y signos sistémicos de la crisis tirotóxica y sus manifestaciones órgano-específicas, asociados a una persistente dificultad respiratoria por síntomas compresivos derivados del gran bocio, se consideró que la tiroidectomía urgente en este caso estaba indicada, dato que se corroboró ante la buena evolución posoperatoria. El tratamiento de la tirotoxicosis es fundamentalmente clínico, sin embargo, la cirugía puede ser útil ante la dificultad en el manejo clínico(AU)

Abstract The thyrotoxic crisis is a complication of poorly treated thyrotoxicosis and is associated with high mortality. This condition requires urgent medical treatment in intensive care units. A 42-year-old woman, with a personal history of high blood pressure, hyperfunctioning thyroid nodule for 18 years, and abandonment of medical treatment since two years ago, presented to the emergency department with paroxysmal nocturnal dyspnea, tachycardia, high blood pressure, large goiter, and anasarca. She was admitted into the intensive care unit with a diagnosis of thyrotoxic crisis and started to receive medical treatment under precise support measures, including orotracheal intubation. Due to the patient's difficult clinical and respiratory management, it was decided to perform urgent surgical treatment. She was performed a total thyroidectomy of partial intrathoracic multinodular goiter and a preventive tracheostomy. The result of pathological anatomy was toxic multinodular goiter. The patient was discharged with normal thyroid function, tracheostomy closure, and good phonation, after a month and a half of hospitalization. Despite the fact that conservative medical treatment is the adequate one for thyrotoxicosis, the systemic symptoms and signs of the thyrotoxic crisis, and its organ-specific manifestations, associated with persistent respiratory distress due to compression symptoms derived from large goiter, urgent thyroidectomy needed to be indicated in this case, a fact corroborated after good postoperative evolution. The treatment of thyrotoxicosis is fundamentally clinical; however, surgery can be useful given the difficulty in clinical management(AU)

Hormone receptor-negative as a predictive factor for pathologic complete response to neoadjuvant therapy in breast cancer / Receptor hormonal negativo como fator preditivo para resposta patológica completa ao tratamento neoadjuvante de câncer de mama

ABSTRACT Objective To define a predictive factor for pathologic complete response, compare the oncologic outcomes associated with the degree of pathologic response after neoadjuvant chemotherapy, and to analyze pathologic complete response as a prognostic factor for overall survival and progression-free survival. Methods A retrospective study of patients admitted to Hospital Estadual Mário Covas and Hospital Anchieta from 2008 to 2012, with locally advanced breast cancer. Hormone receptor status, HER2 status, histologic and nuclear grade, age upon diagnosis and histological type of the tumor were analyzed. Pathologic evaluation of the tumor was subdivided into pathologic complete response, defined by the absence of tumor; intermediate response, considered as a favorable stage; and poor response, considering low-responder patients. Data obtained were submitted to statistical analysis. Results The study included 243 patients. There was an association of pathologic complete response with HER-2 negative, histological grade 3, stage III, hormone receptor negative, positive lymph node, older age and more advanced tumors. However, after multivariate analysis the only predictor of pathologic complete response was the presence of negative hormone receptor. By analyzing the prognostic factors, hormone receptor negative was considered as an independent risk factor, and pathologic complete response was considered as an independent protective factor. Conclusion Hormone receptor negative is predictive of pathologic complete response and is an isolated risk factor for lower progression-free survival and overall survival. Pathologic complete response is a protective factor for these same survival analyses.

RESUMO Objetivo Definir um fator preditivo para resposta patológica completa, comparar os resultados oncológicos associados com o grau de resposta patológica, após quimioterapia neoadjuvante, e analisar a resposta patológica completa como fator prognóstico para sobrevivência global e livre de progressão de doença. Métodos Estudo retrospectivo de pacientes admitidas no Hospital Estadual Mário Covas e Hospital Anchieta, no período de 2008 a 2012, com câncer de mama localmente avançado. Foram utilizados status dos receptores hormonais, proteína HER2, grau histológico e nuclear, idade do paciente ao diagnóstico e tipo histológico do tumor. A avaliação patológica do tumor foi subdividida em resposta patológica completa, definida com ausência de tumor; resposta intermediária, considerada como um estádio favorável; e resposta ruim, considerando os pacientes pouco respondedores. As informações obtidas foram submetidas à análise estatística. Resultados Foram incluídas 243 pacientes. Verificou-se associação de resposta patológica completa entre HER-2 negativo, grau histológico 3, estadiamento III, receptor hormonal negativo, linfonodo positivo, maior idade e tumores mais avançados. Porém, após análise multivariada, o único fator preditivo de resposta patológica completa foi presença de receptor hormonal negativo. Ao analisar fatores prognósticos, receptor hormonal negativo permaneceu como variável independente de risco, e resposta patológica completa, como variável independente de proteção. Conclusão O receptor hormonal negativo é fator preditivo isolado de resposta patológica completa e fator de risco para menor sobrevida livre de doença e sobrevida global. Já a resposta patológica completa é fator protetor para estas mesmas análises de sobrevivência.

Benefits of fasting abbreviation with carbohydrates and omega-3 infusion during cabg: a double-blind controlled randomized trial

Abstract Objective: To assess postoperative clinical data considering the association of preoperative fasting with carbohydrate (CHO) loading and intraoperative infusion of omega-3 polyunsaturated fatty acids (ω-3 PUFA). Methods: 57 patients undergoing coronary artery bypass grafting (CABG) were randomly assigned to receive 12.5% maltodextrin (200 mL, 2 h before anesthesia), (CHO, n=14); water (200 mL, 2 h before anesthesia), (control, n=14); 12.5% maltodextrin (200 mL, 2 h before anesthesia) plus intraoperative infusion of ω-3 PUFA (0.2 g/kg), (CHO+W3, n=15); or water (200 mL, 2 h before anesthesia) plus intraoperative infusion of ω-3 PUFA (0.2 g/kg), (W3, n=14). The need for vasoactive drugs was analyzed, in addition to postoperative inflammation and metabolic control. Results: There were two deaths (3.5%). Patients in CHO groups presented a lower incidence of hospital infection (RR=0.29, 95% CI 0.09-0.94; P=0.023), needed fewer vasoactive drugs during surgery and ICU stay (P<0.05); and had better blood glucose levels in the first six hours of recovery (P=0.015), requiring less exogenous insulin (P=0.018). Incidence of postoperative atrial fibrillation (POAF) varied significantly among groups (P=0.009). Subjects who receive ω-3 PUFA groups had fewer occurrences of POAF (RR=4.83, 95% CI 1.56-15.02; P=0.001). Patients in the W3 group had lower ultrasensitive-CRP levels at 36 h postoperatively (P=0.008). Interleukin-10 levels varied among groups (P=0.013), with the highest levels observed in the postoperative of patients who received intraoperative infusion of ω-3 PUFA (P=0.049). Conclusion: Fasting abbreviation with carbohydrate loading and intraoperative infusion of ω-3 PUFA is safe and supports faster postoperative recovery in patients undergoing on-pump CABG.

Fatores associados a quedas recorrentes em uma coorte de idosos / Factors associated with recurrent falls in a cohort of elderly people

Resumo Introdução Quedas de idosos configuram-se como importante causa de morbimortalidade. Objetivo Verificar a reincidência de quedas e identificar fatores associados a quedas e a quedas recorrentes. Metodologia Estudo de seguimento de 4 anos, por meio de duas ondas de inquérito (2010 e 2014/2015), com uma coorte de 218 idosos, de ambos os sexos e não institucionalizados em Juiz de Fora, MG. Utilizou-se regressão logística multinomial para estimar a associação de cada variável independente com os desfechos analisados. No modelo final foram mantidas as variáveis com p ≤ 0,05. Para cálculo de odds ratio (OR), foi considerado intervalo de confiança de 95%. Resultados 33,5% das pessoas relataram ter caído no ano anterior ao primeiro inquérito. No segundo inquérito, essa frequência foi de 38,5%. Durante o seguimento, 44,5% não relataram quedas, 39% sofreram queda em pelo menos um dos inquéritos e 16,5% manifestaram ter sofrido queda nas duas ondas. Não foram encontradas associações para queda recorrente. Queda no seguimento associou-se a sexo feminino e idade (71 a 80 anos). Conclusão Os resultados evidenciam e ratificam a magnitude com que quedas e quedas recorrentes atingem a população idosa e apontam para a necessidade de estratégias preventivas a partir da identificação de grupos de riscos.

Abstract Introduction For the elderly, falling constitute an important cause of morbidity and mortality. Objective Verify the recurrence of falls and identify factors associated with falls and recurrent falls. Methodology A 4-year follow-up study using two survey waves (2010 and 2014/2015), with a cohort of 218 elderly people, both genders and non-institutionalized, in Juiz de Fora-MG. Multinomial logistic regression was used to estimate the association of each independent variable with the outcomes analyzed. In the final model, variables with p ≤ 0.05 were maintained. Odds Ratio (OR) was calculated with a 95% confidence interval. Results 33.5% of the participants reported falling in the prior year of the first inquiry. In the second inquiry, the frequency was 38.5%. During the follow-up study, 44.5% did not report falls, 39% suffered a fall in at least one of the surveys, and 16.5% reported falling in both waves. No associations for recurrent falls were found. In the follow-up, falls were associated with female gender and age (71 to 80 years old). Conclusion The results demonstrate and confirm the magnitude with which falls and recurrent falls affect the elderly population, and indicate the need for preventive strategies based on the identification of groups at risk.
