Efectos adversos del tratamiento del cáncer oral
2008
- Francisco.Silvestre@uv.es En este estudio se hace una revisión de los efectos adversos más frecuentes por la cirugía de tumores de cabeza y cuello, la radioterapia y la quimioterapia, pues no es infrecuente que el odontólogo general encuentre en su consulta complicaciones como mucositis, xerostomía, necrosis óseas, alteraciones gustativas y otras lesiones que causarán molestias considerables al paciente, disminuyendo su calidad de vida. El papel del odontólogo en el tratamiento multidisciplinario constituye un pilar importante en la prevención, el tratamiento de dichas complicaciones y la disminución de sus secuelas. In this article a revision of most frequent adverse effects of head and …
Oral rehabilitation with the new SG® attachment in a patient treated for oral squamous cell carcinoma
2007
In patients who have undergone surgery and radiotherapy for oral squamous cell carcinoma (OSCC), the posterior oral rehabilitation may prove complex. In addition to the defects produced by surgical ablation of the primary tumor, radiotherapy induces deleterious effects upon the oral tissues. We present the case of a 48-year-old male treated two years before due to OSCC in the retromolar trigone and left lateral wall of the oropharynx. Following study of the case with clinical examination and orthopantomography, a management plan was defined involving rehabilitation of the upper dental arch with fixed ceramometallic prostheses, while in the lower arch we chose a unilateral removable prosthes…
Aplicaciones de la citología exfoliativa en el diagnóstico del cáncer oral
2004
La citología exfoliativa es una técnica sencilla, no agresiva y bien aceptada por los pacientes, por lo que podría ser útil en el diagnóstico precoz del cáncer oral. Sin embargo, su utilización como método diagnóstico de atipias epiteliales y especialmente del carcinoma oral de células escamosas ha perdido importancia, sobre todo debido a su baja sensibilidad representada por el elevado número de resultados falsos negativos. Se atribuye esta baja sensibilidad a diversos factores, entre ellos: toma inadecuada de la muestra, error en la técnica e interpretación subjetiva de los hallazgos citológicos. Afortunadamente, en los últimos tiempos, el desarrollo del análisis cuantitativo, la citomorf…
Factors related to survival from oral cancer in an Andalusian population sample (Spain)
2007
Introduction: Approximately 3% of malignant tumors originate in the oral cavity. The majority are squamous cell carcinomas, and a small percentage, malignant tumors of the salivary glands, lymphoreticular diseases, bone tumors, melanomas, sarcomas, malignant odontogenic tumors and metastases of tumors from other locations. The prognosis of these pathologies depends on the size, infiltration, and site of the lesion, the presence or absence of metastatic spread, and to a certain degree the differentiation of the tumor. The prognosis of an oral cancer remains generally negative, with 5-year survival figures below 50%, producing high rates of mortality and morbidity. Objectives: To evaluate the…
Cavernous sinus metastasis from oropharyngeal squamous cell carcinoma.
2007
Metastasis to the cavernous sinus from head and neck cancer is uncommon and has been previously reported by a few authors. It is usually a late manifestation of the primary tumor and may be the first evidence of a widespread dissemination of the disease. Main clinical findings are those related with involvement of cranial nerves III to VI as they pass through the cavernous sinus. Although diagnosis may be difficult, the appearance of clinical and radiological findings of cavernous sinus involvement in a context of head and neck cancer must alert us about an intracranial metastatic infiltration. In most cases treatment is palliative with radiotherapy and/or chemotherapy. The prognosis of thi…
