ABSTRACT

Introdução: o tratamento do pescoço no carcinoma espinocelular (CEC) de língua oral e soalho de boca sem metástase detectadas clinicamente permance controverso. Objetivo: analisar o resultado após esvaziamento cervical supraomo-hióideo(ECSOH) estendido ao nível IV. Método: analisamos, restrospectivamente, 40 pacientes com estadiamento cl[inico NO e N1 de 1996 a 2002. Havia 29 homenzs e 11 mulheres, cujas idades variaram de 46 a 83 anos (mediana, 63). Foram estadiados como T1 (2), T2(24), T3(13) e T4(1). Todos foram submetidos a ECSOH estendido ao nível IV. Resultados: dentre os 34 pacientes estadiados como N0, os achados histológicos foram confirmados em 29 (85,3%), enquanto que cinco foram estadiados como pN positivo. Assim, havia seis pacientes pN1 e cinco pN2a. Dos seis pacientes estadiados clinicamente como N positivo, não houve falso-positivos. Todos os pacientes com linfonodos positivos foram tratados com radioterapia adjuvante. Recidiva cervical ocorreu em 6,9% dos pacientes N) (2/29), 28,6% pN1(2/7) e 50% dos pN2a (2/4). Foram encontradas metástases ocultas em cadeia IV em dois casos (5%) entre aqueles estadiados como pN2a e nenhuma metástase em cadeia V. Tdoas as recidivas ocorreram nos níveis II e III. Conclusão: uma taxa de 14,7% dos pacientes estadiados como N) clinicamente apresentaram metástases ocultas. Todas as metástases pN1 ocorreram nso níveis I ou II. Cinco por cento dos pN2a apresentaram metástases ocultas em cadeia IV. Recidiva cervical ocorreu em 6,9% dos pacientes pN), 28,6% dos pN1 e 50% dos pN2a. Todas as recidivas ocorreram nos níveis I e II.


Introduction: the neck treatment in the squamous cell carcinoma (SCC) of the oral tongue and floor of the mouth without clinical metastasis remains controversial. Objective: to analyze the outcomeafter supraomohyoid neck dissection (SOHND) extended for level IV for those patients. Methods: we retrospectively analyzed 40 patients with clinically N0 and N1 stage SCC from 1996 to 2002. There were 29 men and 11 women whose ages varied from 46 to 82 (median, 63). They were staged as T1(2), T2(24), T3(13), and T4(1). They underwnt SOHND extended for level IV. Results: camong the 34 patients staged as N0, the histologic findings confirmed that in 29 (85.3%), whereas 5 were staged as pN positive. Thus, there were 6 patients staged a pN1 and 5 patients were pN2a. Among the 6 patients staged as clinical N positive, there was no false-positive case. All patients with node positivity received adjuvant radiation therapy. Neck failure occurred in 6.9% of the pN0 patients (2/29), 28.6% of the pN1 patients (2/7), and 50% of the pN2a group (2/4). Occult metastasis in level IV occurred in 2 cases (5%) among those sateged as pN2a and no one had it at leval V. All recurrences occurred in levels II and III. Conclusion: a rate of14.7% of patients clinically staged as N0 necks showed occult metastasis. All the pN1 metastasis occurred in level I or II. Occult metastasis in level IV occurred in 5% of the pN2a cases. Neck failure occurred in 6.9% of the pNO patients, 28.6% of the pN1 patients, and 50% of the pN2a. All recurrences occurred in levels II and III.
