“…Of the 14 cases with erosive bone defects, 12 showed the expansive pattern and only 2 demonstrated the infiltrative pattern. The actual extension of the tumor roughly corresponded with the radiologic determination of the bone defect, and the tumor did not extend widely beyond the predicted site in any way.…”

Mandibular involvement by squamous cell carcinoma of the lower alveolus: Analysis and comparative study of histologic and radiologic features

et al. 1991

Histologic analysis of squamous cell carcinoma of the lower alveolus shows 2 basic patterns of tumor spread in relation to the mandible: an infiltrative one and an expansive one. While the tumor invades the mandible by destroying the bone or through cortical defects of some spaces in the infiltrative form, the tumor does this only by eroding the bone in the expansive form, in which the degree of bone resorption seems to be proportional to tumor advancement. A comparison between radiologic and histologic features discloses that the radiologically detected bone defects are not necessarily correlated with the patterns of bone involvement. However, most lesions with erosive bone defects show the expansive pattern histologically, and the extent of the radiologically detected bone defect is roughly in accordance with the histologic extent of bone involvement. These results lead us to believe that some squamous carcinoma of the lower alveolus could be treated successfully without sacrificing the continuity of the mandible.

“…A ressonância magnética (RM) é superior à TC na avaliação do envolvimento da mandíbula (2,(10)(11)(12) , incluindo determinação de envolvimento do córtex e avaliação da invasão da medula óssea. A maioria das vantagens da RM deve-se à melhor demonstração dos tecidos moles com esta técnica e também à melhor distinção entre a medula óssea e o córtex.…”

Carcinoma espinocelular de gengiva: análise das imagens de sete casos

et al. 2003

Os autores estudaram sete casos de carcinoma de gengiva atendidos no Serviço de Cirurgia de Cabeça e Pescoço e Otorrinolaringologia e no Serviço de Diagnóstico por Imagem do Complexo Hospitalar Heliópolis, São Paulo, SP, entre 1985 e 1996. Todos os casos eram carcinomas do tipo espinocelular. Os sete pacientes eram do sexo masculino (100%), com idade variando entre 48 e 72 anos (média de 57 anos). Exame de tomografia computadorizada foi realizado em seis (85,6%) dos sete pacientes. Quatro pacientes (57,1%) eram não tratados na ocasião do exame de imagem e três pacientes (42,8%) já tinham tido algum tipo de tratamento (cirurgia ou radioterapia). Além disso, os autores analisaram o local primário e as extensões locais para a mandíbula (5/7 casos; 71,4%), para o soalho da boca (3/7 casos; 42,8%), para o soalho do seio maxilar (1/7 casos; 14,2%) e para o trígono retromolar (1/7 casos; 14,2%). Linfonodos metastáticos foram observados em cinco pacientes (71,4%). Biópsia e exame histopatológico confirmaram todos os casos. Confrontação com achados cirúrgicos foi possível em cinco casos (71,4%).

“…More recent studies, including our own, have not been able to demonstrate similar findings. 6,13,15,18,47 Most clinicians, however, do think that primary tumor location is an important risk factor for mandible involvement because cancers originating on the alveolus, retromolar trigone, and, to a lesser extent, the floor of mouth are more often associated with bone invasion. 6,7,13,14,17,18,28,40,47 Elegant studies by Brown et al 13 and Brown and Browne 47 demonstrated that a critical factor influencing lower jaw invasion was extension of the primary tumor onto the attached gingiva of the alveolus.…”

“…Over the years, several imaging techniques have been investigated for their ability to predict mandibular invasion by tumor, including plain films, 3–13 conventional radionuclide scans, 3,4,6,7,10,12–17 computed tomography (CT) scans, 9,10,13,18–23 and magnetic resonance imaging scans. 13,18,24,25 However, all of these modalities suffer from a lack of accuracy.…”
