Background Chemotherapy is standard neoadjuvant treatment of LA BC. Patients with HER2-positive BC require targeted therapy. Trastuzumab and pertuzumab, which target HER2, with chemotherapy are approved as neoadjuvant therapy, however, treatments with different mechanisms of action might provide a broader range of activity. In this study we evaluated the efficacy and safety of the irreversible ErbB family blocker afatinib, versus trastuzumab or lapatinib in the neoadjuvant treatment of HER2-positive, LA BC. Patients and Methods Treatment-naive, HER2-positive BC patients with stage IIIA, B, C or inflammatory disease were randomized 1:1:1 to daily afatinib (50 mg), lapatinib (1500 mg), or weekly trastuzumab (4 mg/kg loading dose, then 2 mg/kg/wk) for 6 weeks until surgery or follow-up neoadjuvant treatment. The primary end point was objective response rate according to Response Evaluation Criteria in Solid Tumors (version 1.0). Results Recruitment was stopped early because of slow patient enrollment; 29 patients were randomized to afatinib (n = 10), lapatinib (n = 8), or trastuzumab (n = 11). Objective response was seen in 8 afatinib-, 6 lapatinib-, and 4 trastuzumab-treated patients. Eleven patients had stable disease (best response); 1 lapatinib- and 1 trastuzumab-treated patient had progressive disease. All 10 afatinib-treated patients experienced drug-related adverse events (commonly diarrhea, dermatitis acneiform, and paronychia) versus 6 of 8 lapatinib- (diarrhea and rash) and 5 of 11 trastuzumab-treated patients (vomiting and arthralgia). Conclusion Afatinib demonstrated clinical activity that compared favorably to trastuzumab and lapatinib for neoadjuvant treatment of HER2-positive BC, with a safety profile consistent with epidermal growth factor receptor tyrosine kinase inhibitors. © 2015 Elsevier Inc.

Efficacious patient safety monitoring should focus on the implementation of evidence-based practices that avoid unnecessary harm related to healthcare. The ISEP-Brazil project aimed to develop and validate indicators for best patient safety practices in Brazil. The basis was the translation and adaptation of the indicators validated in the ISEP-Spain project and the document Safe Practices for Better Healthcare (U.S. National Quality Forum), recommending 34 best practices. A 25-member expert panel validated the indicators. Reliability and feasibility were based on a pilot study in three hospitals with different management formats (state, federal, and private). Seventy-five best practice indicators were approved (39 structure; 36 process) for 31 of the 34 recommendations. The indicators were considered valid, reliable, and useful for monitoring patient safety in Brazilian hospitals.

The introduction of agents such as thalidomide, lenalidomide, and bortezomib has changed the management of patients with multiple myeloma who are not eligible for autologous transplantation, many of whom are elderly. We sought to compare three thalidomide-based oral regimens among such patients in Latin America. We randomized patients with newly diagnosed multiple myeloma with measurable disease to one of the following regimens: melphalan, prednisone, and thalidomide (MPT); cyclophosphamide, thalidomide, and dexamethasone (CTD); and thalidomide and dexamethasone (TD). The TD arm was closed prematurely and was analyzed only descriptively. The primary endpoint was the overall response rate (ORR), whereas progression-free survival (PFS) and overall survival (OS) were secondary endpoints. The accrual rate was slower than expected, and the study was terminated after 82 patients had been randomized. The ORRs were 67.9% with MPT, 89.7% with CTD, and 68.7% with TD (p=0.056 for the comparison between MPT and CTD). The median PFS was 24.1months for MPT, 25.9months for CTD, and 21.5months for TD. There were no statistically significant differences in PFS or OS between MPT and CTD. In an unplanned logistic regression analysis, ORR was significantly associated with treatment with CTD (p=0.046) and with performance status of 0 or 1 (p=0.035). Based on the current results, no definitive recommendations can be made regarding the comparative merit of the regimens tested. Nevertheless and until the results of further studies become available, we recommend either CTD or MPT as suitable frontline regimens for patients with multiple myeloma who are not candidates to transplantation in settings where lenalidomide and bortezomib are not available.

Introduction: Acute lymphocytic leukemia is a type of cancer most common in children and it is characterized by excessive and disordered immature leukocytes in the bone marrow. Aim: Identify most frequent oral manifestations in children with acute lymphocytic leukemia under chemotherapy treatment. Methodology: The research was conducted on the eletronic database PubMed/Medline, Science Direct, Scielo and Scopus. It has been sought papers with full presentation, wrote in Portuguese, English and Spanish, published between January 1992 and April 2013. Results: From studies primarily selected, only eight met the criteria of inclusion. All studies performed intraoral examinations to diagnose oral lesions. According to results, the most frequent lesions were mucositis, candidiasis, periodontitis and gingivitis. The oral health condition from acute lymphocytic leukemia carriers varied according oral hygiene of the patient. Conclusion: The results of studies identified such a great part of patients with ALL presented some lesion in oral cavity during or after chemotherapy treatment. The dentist surgeon needs to recognize oral manifestations and intervene in the oral health of patients with ALL, contributing and helping with treatment. © 2014 Associação Brasileira de Otorrinolaringologia e Cirurgia Cérvico-Facial.

A solitary pulmonary nodule is a common, often incidental, radiographic finding. The investigation and differential diagnosis of solitary pulmonary nodules remain complex, because there are overlaps between the characteristics of benign and malignant processes. There are currently many strategies for evaluating solitary pulmonary nodules. The main objective is to identify benign lesions, in order to avoid exposing patients to the risks of invasive methods, and to detect cases of lung cancer accurately, in order to avoid delaying potentially curative treatment. The focus of this study was to review the evaluation of solitary pulmonary nodules, to discuss the current role of18Ffluorodeoxyglucose positron-emission tomography, addressing its accuracy and cost-effectiveness, and to detail the current recommendations for the examination in this scenario. © Colégio Brasileiro de Radiologia e Diagnóstico por Imagem.

Gene | Year: 2015

Germ-line mutation in CDH1 gene is associated with high risk for Hereditary Diffuse Gastric Cancer (HDGC) and Infiltrative Lobular Carcinoma (ILC). Although somatic CDH1 mutations were also detected in ILC with a frequency ranging from 10 to 56%, CDH1 alterations in more frequent infiltrative ductal carcinoma (IDC) appear to be rare, and no association with germ-line CDH1 mutation and IDC has been established. Here we report the case of a woman diagnosed with IDC at 39. years of age, presenting extensive familial history of cancer at multiple sites with early-age onset and with no case of HDGC. Deep sequencing have revealed CDH1 missense mutation c.1849G>A (p.Ala617Thr) in heterozygous and four BRCA2 single nucleotide polymorphism in homozygosis. In this family, the mutation c.1849G>A in the CDH1 gene is not related to HDGC nor ILC. Therefore, here we highlight that multigene analysis is important to detect germ-line mutations and genetic variants in patients with cancers at multiple sites in the family, even if inconclusive genetic counseling can be offered, since hereafter, medical awareness will be held. © 2015 Elsevier B.V.

Solitary pulmonary nodule corresponds to a common radiographic finding, which is frequently detected incidentally. The investigation of this entity remains complex, since characteristics of benign and malignant processes overlap in the differential diagnosis. Currently, many strategies are available to evaluate solitary pulmonary nodules with the main objective of characterizing benign lesions as best as possible, while avoiding to expose patients to the risks inherent to invasive methods, besides correctly detecting cases of lung cancer so as the potential curative treatment is not delayed. This first part of the study focuses on the epidemiology, the morfological evaluation and the methods to determine the likelihood of cancer in cases of indeterminate solitary pulmonary nodule. © Colégio Brasileiro de Radiologia e Diagnóstico por Imagem.

The aim of this research was to study prognostic parameters of CRC by analyzing clinical and pathological variables associated with cancer patients at a northeastern Brazilian Hospital. This was a retrospective study evaluating CRC-diagnosed patients across a 10-year period (1995-2005) at Dr. Luiz AntÔnio Hospital in Natal, RN, Brazil. Data were collected from patients' medical files. A total of 358 patients were included over the 10-year period. The average age at diagnosis was 58.8 years (S.D = 15.26), 48.3% of the patients were males and 51.7% were females. Alcohol consumption significantly increased the chance of dying (p < 0.023) from colorectal cancer; this increased risk of death was approximately 71%, compared to 52.2% of the non-alcoholics. In addition, tobacco increased the chance of developing high TNM stage tumors (level III, IV; p < 0.001). Another risk factor for increased mortality was a family history for colorectal cancer (p < 0.002).Our analysis found that patients with an unhealthy lifestyle and/or family history of colorectal cancer were more likely to develop advanced stage colorectal cancer and to have a poor disease prognosis compared to patients with healthy lifestyle and/or sporadic colorectal cancer. These data suggest that a mass screening program should be implemented in northeastern Brazil in order to better prevent and treat colorectal cancer. © 2013 Elsevier GmbH.

BACKGROUND: Due to their complexity and risks, mesenteric-portal axis resection and reconstruction during the pancreatectomy procedure were not recommended back in the early nineties. However, as per technical improvements and the reduction in morbidity and mortality rates, they have been routinely indicated in large medical centers.AIM: To show results from cases of patients subjected to mesenteric-portal axis resection during pancreatectomy.METHOD: Patients subjected to mesenteric-portal axis resection during pancreatectomy were prospectively and consecutively assessed. The procedure was indicated according to anatomical criteria defined by imaging exams or intraoperative assessment.RESULTS: Ten patients, half of them were male, with mean age of 55.7 years (40-76) were included. The most frequent underlying diseases were pancreatic adenocarcinoma and Frantz tumor. The circumferential resection of the portal vein associated with the superior mesenteric vein with splenic vein ligature (4 cases=40%) and the primary anastomosis of the vascular stumps (5 cases=50%) were, respectively, the most performed types of vascular resection and reconstruction. Surgery time ranged from 480 to 600 minutes (average=556 minutes) and postoperative hospitalization time ranged from 9 to 114 days (average=34.8 days). Morbidity rate was 60%, and clinical pancreatic fistula (grade B and C) was the most common complication (3 cases=30%). Mortality rate was 10% (1 case).CONCLUSION: Mesenteric-portal axis resection is a valid technical procedure. It should be taken into account after a clinical assessment that included not only the patients' clinical condition but also the technical and anatomical conditions of the mesenteric-portal axis tumor infiltration as well as life expectancy based on the patient's cancer prognosis.

to report the groups experience with a series of patients undergoing pancreatic resection presenting null mortality rates.we prospectively studied 50 consecutive patients undergoing pancreatic resections for peri-ampullary or pancreatic diseases. Main local complications were defined according to international criteria. In-hospital mortality was defined as death occurring in the first 90 postoperative days.patients age ranged between 16 and 90 years (average: 53.3). We found anemia (Hb < 12g/dl) and preoperative jaundice in 38% and 40% of cases, respectively. Most patients presented with peri-ampullary tumors (66%). The most common surgical procedure was the Kausch - Whipple operation (70%). Six patients (12%) needed to undergo resection of a segment of the mesenteric-portal axis. The mean operative time was 445.1 minutes. Twenty two patients (44%) showed no clinical complications and presented mean hospital stay of 10.3 days. The most frequent complications were pancreatic fistula (56%), delayed gastric emptying (17.1%) and bleeding (16%).within the last three decades, pancreatic resection is still considered a challenge, especially outside large specialized centers. Nevertheless, even in our country (Brazil), teams seasoned in such procedure can reach low mortality rates.
