RESUMO

PURPOSE: To describe a new B-mode ultrasound examination technique to assess cheek tumors. MATERIALS AND METHODS: 30 cheek oral cavity lesions of different histological types (11 benign and 19 malignant) from 23 patients (11 women and 12 men, 7-82 years old, mean age of 49.5 years) were analyzed. Transcutaneous oral B-mode ultrasound (5-12 MHz transducer) was carried out in two stages. Initially it was performed conventionally with an empty mouth. Next, the patient was asked to keep their oral cavity filled with water (like when using a mouthwash) during imaging for the new test examination technique. The anatomical layers of this region and the characteristics of the tumors were evaluated. Lesions were classified as ill defined, partially defined, or defined. Conventional findings were compared to those of the new technique using the Wilcoxon signed-rank test. Ultrasound results were compared to histological findings analyzed by an independent team. RESULTS: The conventional empty mouth technique was able to confidently define lesion extension in only 6 of the 30 lesions, while the water-filled mouth technique was able to confidently define lesion extension in 29 of the 30 lesions (p<0.00001). CONCLUSION: We present a novel technique that dramatically improves ultrasound staging of cheek oral cavity tumors. In addition to the increase in ultrasound accuracy, this technique does not require any special equipment or extra cost, is very well tolerated by patients, and thus should be considered in the evaluation of every patient undergoing transcutaneous cheek ultrasound for oral cavity lesion characterization.

RESUMO

Introdução: O espaço perineural é reconhecido como rota de propagação do carcinoma espinocelular (CEC) e, quando acometido, tem sido relacionado com pior prognóstico, maior recorrência e menor tempo de sobrevivência. Contudo, seu papel nos tumores precoces de cavidade oral ainda não está totalmente esclarecido. Objetivos: comparar a sobrevivência global e livre de doença entre pacientes com carcinoma espinocelular precoce de língua oral e soalho de boca com e sem invasão perineural; comparar a ocorrência de fatores clínicos e anátomo-patológicos entre os grupos; e descrever os casos de óbito para análise crítica da realização do tratamento radioterápico adjuvante. Métodos: Foi realizado estudo retrospectivo longitudinal de caso-controle, de 42 pacientes operados por CEC precoce (T1/T2 N0) de língua oral e soalho de boca, divididos em dois grupos: com invasão perineural (n=16) e sem invasão (n=26). Variáveis clínicas, anátomo-patológicas e de seguimento, incluindo realização de tratamento adjuvante foram comparadas. Resultados: No grupo com invasão perineural houve maior freqüência de homens (p=0,008), óbito relacionado (p=0,015), quantidade de cigarro consumida (p=0,042) e menor freqüência de não etilistas. As médias do maior diâmetro (p=0,046) e da espessura (p=0,002) do CEC primário foram maiores nesse grupo. Conclusões: Houve menor sobrevivência global no grupo de doentes com CEC precoce de língua oral e soalho com invasão perineural (p=0,019), apesar da maior freqüência de radioterapia adjuvante. Todos os óbitos relacionados ocorreram no grupo com invasão perineural, por recidiva local, sendo que, em dois casos, nenhuma outra característica de mau prognóstico foi observada. À análise multivariada, a presença de invasão perineural foi indicada como fator associado ao óbito correlacionado, de maneira não significante (p=0,275). Os resultados favorecem a indicação de tratamento radioterápico adjuvante.


Introduction: perineural space is known as a pathway for spreading of the squamous cell carcinoma (SCC). Its invasion has been associated with worse prognosis, greater rates of recurrence and lower survival rates. However, its impact on the initial oral cavity tumors is not well established. Objectives: to compare global survival and disease free survival between patients with initial SCC of tongue and floor of mouth, with and without perineural invasion; to compare clinical and pathological features between the two groups; and to describe the cases of death for a critical analysis of the use of adjuvant radiotherapy. Methods: retrospective longitudinal case-control study of 42 patients surgically treated for initial SCC (T1/T2 N0 ? UICC-2002) of oral tongue and floor of mouth. The patients were divided into two groups: with (n=16) and without (n=26) perineural invasion. Clinical and pathological features, as well as the follow-up and treatment information were compared. Results: the group with perineural invasion presented a higher frequency of male patients (p=0.008) and of tobacco use (p=0.042) and lower frequency of non users of alcohol. The mean of greater tumor diameter (p=0.046) and thickness (p=0,002) were higher in this group. Those patients also had higher disease specific death (p=0.015) and a lower survival (p=0.019), regardless of a higher frequency of adjuvant treatment with radiotherapy. All disease specific deaths occurred in this group and, in two of these cases, no other known features of worse prognosis were observed. At the multivariate analysis, the perineural invasion was related to disease-specific death in a non significant manner (p=0.275). Conclusion: These results point out the perineural invasion as a feature of worse prognosis, even in initial tumors and despite more aggressive treatment.
