Entire hemithorax irradiation for Masaoka stage IVa thymomas

Thymomas are rare neoplasms that have an indolent growth with a preferentially intra-thoracic dissemination pattern. Surgery is currently the standard treatment of thymomas; however radiotherapy is often used in an adjuvant setting due to a high sensitivity of these tumors to such treatment. Postoperative entire hemithoracic irradiation has been used in selected Masaoka stage IVa cases after complete surgical e...

Atividades antinociceptiva e antiinflamatória do óleo essencial de cascas de Du...

O presente trabalho avaliou as atividades antinociceptiva e antiinflamatória do óleo essencial de cascas de Duguetia lanceolata. Para isto, foram realizados os testes de contorções abdominais induzidas por ácido acético; tempo da lambida da pata induzida por formalina; e edema de pata induzido por carragenina. O número de contorções abdominais (DE50 = 21,79 mg/kg) e o tempo da lambida da pata 1ª fase (DE50 = 5,...

Avaliação da qualidade de matérias-primas de ruibarbo utilizadas em formulações...

As plantas denominadas de ruibarbo sintetizam antraquinonas e taninos, que são responsáveis pelos efeitos laxante e adstringente, respectivamente. Análises da qualidade de cinco matérias-primas de ruibarbo foram realizadas a fim de detectar adulterações. As reações para antraquinonas e taninos foram positivas. Os constituintes rapônticos foram observados na amostra de Rheum palmatum (2). As medidas de cinzas to...

Monoclonal antibodies. General approach and radioimmunotherapy.

Two major obstacles to systemic cancer therapy are the lack of specificity of therapeutic modalities and the intrapatient and interpatient heterogeneity of cancer cells. Because of their natural specificity, antibodies directed against tumor specific or tumor associated antigens have been raising interest in oncology. This article makes an overview of the basic principles of monoclonal antibodies, their limitat...

Gliosarcomas.

Gliosarcomas are rare tumors of the central nervous system with a poor prognosis. Histologically these tumors are characterized by an admixture of neoplastic glial cells and sarcomatous elements. Due to the scarcity of data in literature, the diagnosis is often missed and treatment is difficult. The authors report three cases of cerebral gliosarcomas and review the literature on this subject. ; Gliosarcomas ar...

The role of external radiotherapy in the treatment of medullary carcinoma of th...

Medullary carcinoma of the thyroid represents 3 to 10% of all thyroid cancers. Surgery is the main treatment. External beam radiotherapy has a fundamental role in the treatment of residual disease following surgery, in cases of cervical node involvement, and in unresectable tumors. Between 1975 and 1993, 12 patients with medullary carcinoma of the thyroid were treated at the Department of Radiotherapy of the Po...
