Análise comparativa de enxertos de gordura em refinamentos de reconstrução mamária com e sem suplementação de células-tronco

INTRODUÇÃO: Os enxertos de gordura tem se mostrado como uma poderosa técnica cirúrgica em reconstrução mamaria secundária e os enxertos enriquecidos com células-tronco, além de suas ações parácrinas, vem apresentando resultados encorajadores no que tange a persistência volumétrica. OBJETIVO: Este estudo clínico teve como objetivo analisar comparativamente quantitativa e qualitativamente enxertos de gordura enriquecidos com células da fração vásculoestromal em reconstrução mamária secundária e a incidência de complicações. MÉTODO: Nós desenvolvemos um método que produz enxertos de gordura, na sala de cirurgia, em uma taxa de enriquecimento maior que os já publicados (2:1). Este estudo clínico prospectivo e controlado analisou qualitativa e quantitativamente enxertos de gordura com (GT - grupo tronco) e sem (GC - grupo controle) adição das células da fração vásculo-estromal fresca em reconstrução mamária secundária; através de volumetria mamária por RNM de mamas, imunofenotipagem e contagem celular. Também foram estudados os resultados estéticos, a satisfação das pacientes e as complicações. RESULTADOS: A persistência volumétrica no GT foi 78,9% e 51,4% no GC, entretanto não houve diferença estatisticamente significativa entre os grupos. CD90 foi o marcador mais expresso e que alcançou diferença significante e ao mesmo tempo apresentou correlação positiva entre a sua expressão e a persistência volumétrica (r=0.651, p=0.03). Necrose gordurosa ocorreu, isoladamente em 4 pacientes do GT submetidas à radioterapia e nenhuma paciente do GC apresentou este evento. Desta forma, pacientes do GC mostraram tendência de estar mais satisfeitas com o enxerto de gordura. Nos dois grupos, os resultados estéticos foram iguais e não foram observadas recidivas loco-regionais. CONCLUSÃO: Os resultados do enriquecimento em uma taxa maior que as já publicadas são encorajadores, apesar de a persistência volumétrica não ter alcançado diferença estatisticamente significante entre os grupos. Enxertos de gordura enriquecidos na proporção 2:1 podem não ser indicados para pacientes submetidas à radioterapia apesar de terem se mostrados seguros num tempo de seguimento de 3 anos

Second St. Gallen European Organisation for Research and Treatment of Cancer Gastrointestinal Cancer Conference: consensus recommendations on controversial issues in the primary treatment of rectal cancer

Primary treatment of rectal cancer was the focus of the second St. Gallen European Organisation for Research and Treatment of Cancer (EORTC) Gastrointestinal Cancer Conference. In the context of the conference, a multidisciplinary international expert panel discussed and voted on controversial issues which could not be easily answered using published evidence. Main topics included optimal pretherapeutic imaging, indication and type of neoadjuvant treatment, and the treatment strategies in advanced tumours. Here we report the key recommendations and summarise the related evidence. The treatment strategy for localised rectal cancer varies from local excision in early tumours to neoadjuvant radiochemotherapy (RCT) in combination with extended surgery in locally advanced disease. Optimal pretherapeutic staging is a key to any treatment decision. The panel recommended magnetic resonance imaging (MRI) or MRI + endoscopic ultrasonography (EUS) as mandatory staging modalities, except for early T1 cancers with an option for local excision, where EUS in addition to MRI was considered to be most important because of its superior near-field resolution. Primary surgery with total mesorectal excision was recommended by most panellists for some early tumours with limited risk of recurrence (i.e. cT1-2 or cT3a N0 with clear mesorectal fascia on MRI and clearly above the levator muscles), whereas all other stages were considered for multimodal treatment. The consensus panel recommended long-course RCT over short-course radiotherapy for most clinical situations where neoadjuvant treatment is indicated, with the exception of T3a/b N0 tumours where short-course radiotherapy or even no neoadjuvant therapy were regarded to be an option. In patients with potentially resectable tumours and synchronous liver metastases, most panel members did not see an indication to start with classical fluoropyrimidine-based RCT but rather favoured preoperative short-course radiotherapy with systemic combination chemotherapy or alternatively a liver-first resection approach in resectable metastases, which both allow optimal systemic therapy for the metastatic disease. In general, proper patient selection and discussion in an experienced multidisciplinary team was considered as crucial component of care.

Avaliação da imagem corporal de mulheres submetidas à cirurgia oncológica mamária

Breast cancer is the second type of cancer that affects more women of reproductive age in Brazil. Surgical treatments include: conserving surgery or mastectomy. Aimed to evaluate body image of women undergoing breast cancer surgery, based on the scale Body Image After Breast Cancer Questionnaire. It is a descriptive, exploratory, transversal, with a quantitative approach. Data were collected in Norte-riograndense League Against Cancer, between the months from March to May 2015, after consideration of the Research Ethics Committee of that institution CAEE 35155714.1.0000.5293. The study population consisted of women undergoing breast onco-surgery. To calculate the sample considered the finite population, totaling 120 subjects, collected four guys the most. Data were analyzed by the software Statistical Package for Social Sciences version 20.0. The domain scores of the scale were evaluated using descriptive and inferential statistics. The surgical group mastectomy without reconstruction showed greater impairment of body image in the field "vulnerability", "Care for the body" and "transparency" in relation to other surgical types, and suggests susceptibility to cancer, body appearance and worry that disturb other. The Kruskal-Wallis test showed greater dissatisfaction with body image in the fields "body Stigma" and "transparency" to the radical neoplastic surgery over other surgical types. Dissatisfaction with body image and physical appearance was detected in this study in all six image fields present in scale, with emphasis on the "body Stigma" and "Transparency". This means that the body image disorder is formulated based on the perception of others about themselves and not by perception "self", which justifies the concern with appearance, with body and hide the consequences stemmed cancer. It is expected that the data obtained from the evaluation of body image presented in this study contribute to enable the assistance to oncocirurgiada woman breast integral, essential for the practice of Nursing.

PREVALENCE AND FACTORS ASSOCIATED WITH THE PERFORMANCE OF MAMMOGRAPHY AND PAP SMEAR TEST

Objective: To estimate the prevalence and factors associated with the performance of mammography and pap smear test in women from the city of Maringá, Paraná. Methods: Population-based cross-sectional study conducted with 345 women aged over 20 years in the period from March 2011 to April 2012. An interview was carried out using a questionnaire proposed by the Ministry of Health, which addressed sociodemographic characteristics, risk factors for chronic noncommunicable diseases and issues related to mammographic and pap screening. Data were analyzed using bivariate analysis, crude analysis with odds ratio (OR) and chi-squared test using Epi Info 3.5.1 program; multivariate analysis using logistic regression was performed using the software Statistica 7.1, with a significance level of 5% and a confidence interval of 95%. Results: The mean age of the women was 52.19 (±5.27) years. The majority (56.5%) had from 0 to 8 years of education. Additionally, 84.6% (n=266) of the women underwent pap smear and 74.3% (n=169) underwent mammography. The lower performance of pap smear test was associated with women with 9-11 years of education (p=0.01), and the lower performance of mammography was associated with women without private health insurance (p<0.01). Conclusion: The coverage of mammography and pap smear test was satisfactory among the women from Maringá, Paraná. Low education level and women who depended on the public health system presented lower performance of mammography.

Experiencias de vida en mujeres con cáncer de mama en quimioterapia

Introducción: El cáncer de mama es una patología muy frecuente y los tratamientos, como la quimioterapia, afectan las experiencias de vida y el psiquismo de la mujer. Los estudios en que se trate de entender la experiencia de la quimioterapia son escasos en Colombia. Objetivos: entender las consecuencias del tratamiento con quimioterapia en las experiencias de vida de la mujer con cáncer en el aspecto psicosocial para mejorar los elementos psicoterapéuticos y las decisiones médicas. Metodología: Se utilizó un método cualitativo-interpretativo utilizando las herramientas analíticas de la teoría fundamentada y teniendo como marco de referencia el modelo ecológico de Bronfrenbrenner. Resultados: Se desarrollaron las siguientes categorías como explicación del fenómeno: 1. Experiencias de cambio en la corporalidad y reacciones emocionales 2. Significados del tratamiento, nuevas creencias y nuevos objetivos vitales 3. Experiencias con la familia y la comunidad 4. Experiencias con otros pacientes y el equipo médico. Conclusiones: Este estudio muestra que la mujer sometida a tratamiento con quimioterapia tiene cambios en su psiquismo y sus relaciones interpersonales. Las mujeres terminan aceptado los cambios en su vida pero admiten la necesidad de acompañamiento psicológico durante el proceso para evitar sufrimientos innecesarios.

Análise das oportunidades de diagnóstico precoce para as neoplasias malignas de mama

OBJETIVOS: O estudo procurou identificar e analisar as oportunidades de diagnóstico precoce para neoplasias malignas de mama, disponíveis para as mulheres do município de Botucatu. MÉTODOS: Foram entrevistadas por telefone, segundo sorteio aleatório, 261 mulheres com idade de 30 anos ou mais. RESULTADOS: A média de idade foi de 51 anos e 49,45% das entrevistadas apresentaram escolaridade de nove anos ou mais; 80% receberam orientações gerais sobre prevenção do câncer de mama e 86,9% orientações específicas sobre autopalpação; 78,9% das mulheres realizaram o auto-exame das mamas e destas somente 27% o fizeram corretamente. O exame clínico das mamas foi realizado em 76,2% das entrevistadas e a mamografia em 35,6%; se o exame de mamografia fosse solicitado por médicos e estivesse disponível, 83,1% das mulheres estariam dispostas a realizá-lo. CONCLUSÃO: A prevalência e a mortalidade da doença são maiores nas mulheres idosas. Neste estudo observou-se que estas apresentaram uma taxa menor de oportunidades de diagnóstico precoce, pois eram menos informadas sobre a periodicidade correta da autopalpação e apresentaram uma menor freqüência de mamografia e de exame clínico das mamas do que as mais jovens. O grau de escolaridade mostrou também significância estatística, visto que as mulheres com mais anos de estudo tiveram melhores oportunidades do que as com pouco estudo.

Avaliação da resposta à quimioterapia primária em amostra de mulheres brasileiras com tumores de mama localmente avançados

PURPOSE: to evaluate the loco-regional response to primary chemotherapy in patients with breast cancer at stages II and III. METHODS: a retrospective and analytical clinical study carried out in 97 patients with an average age of 52.2 years old, with breast cancer at stages II and III, attended from January 1993 to December 2004, and submitted to 3 to 4 cycles of primary chemotherapy with 5-fl uorouracil - 500 mg/m2, epirubicin - 50 mg/m2 and cyclophosphamide - 500 mg/m2 or doxorubicin - 50 mg/m2 e cyclophosphamide - 500 mg/m2, and then to loco-regional surgical conservative or radical surgical treatment. Chi-square and Fisher's exact tests were used to study the association among the variables (age, menopausal state, pre-chemotherapy tumoral volume, axillary condition, stage, therapeutic scheme and number of cycles), while Pearson's correlation coefficient was used for the quantitative variables (tumoral volume according to the anatomo-pathological study and the post-chemotherapy clinical tumoral volume. The significance level was 5%. RESULTS: there were 56.8% of cases at stage II and 43.2% at stage III. Approximately 50% of the patients received FEC50 and 50% AC. Objective clinical response with primary chemotherapy was obtained in 64.9% of the cases. Full clinical response occurred in 12.3% of patients, while full pathological response occurred in 10.3% of the cases. CONCLUSIONS: there was a statistically significant correlation between the number of cycles and the response to primary chemotherapy. Patients who received 4 cycles had better response than those who received 3 cycles. There was also a statistically significant concordance between the evaluation through clinical examination of the response to primary chemotherapy and the pathological findings. No statistically significant correlation was observed concerning age, menopausal status, tumoral volume, and pretreatment of axillary damage.

Estudo com familiares de pacientes com câncer de mama: abordando conhecimento sobre fatores de risco

Breast cancer (BC) is the most common malignancy in women worldwide, with one million new cases confirmed each year. This study aimed at identifying the knowledge of patients? relatives concerning the risk factors (RF) for BC. It is a descriptive quantitative study carried out in the Chemotherapy Technical Division of a University Hospital in São Paulo state, Brazil, from September to October 2006. Only female (30) relatives were included due to the fact that BC is more frequent in females. The major RF cited were family history for BC 33.3% (10), smoking 16.6% (5), alcoholic-drink consumption 10% (3), animal-fat-rich diet 3.3% (1). Other factors such as not breastfeeding, environmental factors, use of oral contraceptives and hormone-replacement therapy were mentioned by 10% (3) of the relatives. It was concluded that the relatives of patients undergoing chemotherapeutic treatment showed to have little knowledge concerning RF for BC. Hence, it is important to rethink the inclusion of the health education process in the family scenario. This issue reaches far beyond thesimple transmission of information. Healthcare professionals and nurses in particular, must focus on these individuals? social context, values, beliefs and needs.
