Mortalidade por neoplasias no Brasil (1980/1983/1985): agrupamento dos Estados, comportamento e tendências

Examinou-se a mortalidade por neoplasias no Brasil, utilizando-se dados oficiais do Ministério da Saúde, abrangendo 26 Unidades da Federação e 13 diferentes localizações neoplásicas, para os anos de 1980, 1983 e 1985. As Análises de Agrupamento e de Componentes Principais revelaram comportamento heterogêneo entre regiões do país, com relação às 13 variáveis estudadas, sendo que os principais elementos discriminantes foram as neoplasias malignas da traquéia/brônquio/pulmão, seguidas das do estômago, esôfago, cólon e pâncreas. Análises complementares evidenciaram tendência de crescimento das taxas de mortalidade para as neoplasias malignas da próstata (17,74%), da traquéia/brônquio/pulmão(15,22%), da mama (11,32%), do pâncreas (10,23%), do cólon (8,08%), do colo uterino (6,45%) e da laringe (6,36%). Houve redução da mortalidade por neoplasias benignas/carcinoma in situ/ outras (27,37%), por neoplasias malignas no reto sigmóide/ânus (7,67%), do estômago (5,31%), de outro local do útero não especificado (2,56%), por leucemia (0,70%) e por neoplasias malignas do esôfago (0,44%). As neoplasias malignas do estômago foram a principal causa de morte por câncer no Brasil, representando 21,30% do total médio, seguidas das neoplasias malignas da traquéia/brônquio/pulmão(17,49% do total médio). Destacam-se os altos índices de mortalidade por neoplasias malignas do esôfago no Estado do Rio Grande do Sul.

Modelos de tratamento para adenocarcinomas de próstata tratados por radioterapia conformacional 3D

Radiotherapy is a branch of medical physics related to the treatment of malignant neoplasm, being an important instrument in the fight against cancer, when combined with the effort of a multidisciplinary team, composed of, physicians, physicists, nurses and technicians. Every year more than 3.5 million new cases of cancer are recorded in the world, being the prostate cancer responsible for approximately 25% of this amount (INCA and IARC, 2008). In this type of cancer, radiotherapy is a method indicated for treatement. The technological advance in this area over years has allowed a greater accuracy in the tumor location, more conformation of the radiation beam around the tumor, reducing the dose in healthy tissues and a consequent dose increase on treatment (Bedford et al., 1999). A radiotherapy planning, in which the physicist develops an important role, is composed of several steps, including choosing the best configuration of treatment beams. This choice has a close relationship with success of therapy and is critical to achieve the best distribution of dose inside the tumor and expose the least as possible the healthy tissue to radiation. In this work, two options for setting up camps in the first phase in a treatment of prostate cancer were simulated in computer planning: 4 fields orthogonal or “Box” with gantry angles in 00, 1800, 2700 e 90° and 4 fields angled or “X” (1350, 450, 3150 e 2250). The percentage of the rectal volume exposed to 40, 50, 60, 72 and 76 Gy should be limited to 60, 50, 25, 15 and 5% respectively (Greco et al., 2003). The femoral toxicity have limited dose by 70% of the total dose prescribed in a prostate treatment (Bedford et al., 1999). The planning of 27 patients with prostate adenocarcinoma submitted to 3D conformal radiotherapy were accompanied. As a result, it was assessed that the best TCP (tumor control probability)...

Radioterapia em câncer de mama: importância da determinação da curva de isodose

The study analyzed contours of the thoracic region of patients undergoing radiotherapy of breast tumors in Hospital Manuel de Abreu of Bauru (institution 1) and the Hospital da Faculdade de Medicina of Botucatu (Institution 2). Were prepared isodose curves corresponding to the contours of the patient, which were presented for radiotherapists doctors both hospital services that enabled the choice of the curve isodose that provides the best distribution of radiation dose in the irradiated volume. Some boundaries were digitized in one institution and sent for preparation of isodose lines in the institution 2, both curves plotted in each of the institutions and for the same contour, were compared, showing that the methodology of Curves of distance is feasible and reliable, while optimizing the routine procedures regarding the handling of isodose plans provided by different radiation equipment. It compares the calculation of the exposure time determined using the isodose curve selected by calculating the value obtained considering the PDP at the point of the middle line of separation between the internal and external fields, the difference between the two methods for determining exposure time was around 2.4%. A study on the angle of the radiation beam at the input field (region breast-air) was conducted showing that, once known a tangent angle of the input beam, one can estimate the angle of the wedge filter used in some procedures for uniformity of dose within the irradiated volume compensation and the lack of tissue in the treatment volume. A comparative study between the isodose curves produced manually with the curves obtained in a two-dimensional computer system, the computer system showed that provides further information regarding the dose gradient within the irradiated volume, in addition to reducing the time spent in preparing the curves isodose

Uma revisão sobre o uso de medicamentos naturais para tratamento de tumores

This study objective was to review a selection of publications on the treatment of benign and malignant tumors with the use of natural medicines obtained from terrestrial and marine flora, both for use in chemotherapy and photodynamic therapy. There are many medications already being used for this purpose and many are still being tested in vivo and in vitro, but all with great future prospects for inclusion in the market

El autocuidado y apoyo social de mujeres de un proyecto de seguimiento mamográfico en Porto Alegre/Brasil

Objective: Identify preventive self-care practices and analyze the configurations of the network support for women with and without breast cancer registered in a mammography-monitoring project from Porto Alegre/Brazil.Method: a mixed sequential delimitation was performed, which expanded the results of the quantitative step (cross and correlation section) in a qualitative step (narrative interviews). 37 women diagnosed with breast cancer (group 1) and 72 without this diagnosis (group 2 – monitoring) participated. The following instruments were used: Assessment Questionnaire Self-care Ability (ASA-A) and Assessment Questionnaire Perceived Social Support and Community. There were performed descriptive analysis and comparison of means (t test and ANOVA) between the two groups. To deepen the understanding of the data, we selected four women with breast cancer with extreme levels on the scale of Social Support to participate in the biographical narrative interviews.Results: the analysis indicate that women who had breast cancer have better self-care practices than the women from the monitoring project (t = 1.791, P = 0.027). As for the analysis of social support, there were no statistically significant differences between the two groups. All participants have an average level of perceived social and community support. It was highlighted by the qualitative data that it was after the diagnosis of breast cancer that women lived self-care aspects they had not previously experienced.Conclusions: the self-care was significantly bigger in the group of women with breast cancer, where the cancer diagnosis was a trigger to increase self-care.
