ABSTRACT
A retrospective study was conducted on 46 cases of squamous cell carcinoma of the lip with oncologic follow-up of 2 to 10 years. Lesions staged as T2N0 were found to behave differently according to size. Forty-six cases of squamous cell carcinomas of the lip were staged and compared. The 14 cases of T2N0 lesions detected in the sample were divided into two subgroups. T2aN0 (2.0-3,0 cm) and T2bN0 (3.1-4.0 cm), which were compared in terms of rate of local recurrence and cervical metastasis by the exact Fisher test. Cure rates for group T1N0 (82 percent) and subgroup T2aN0 (86 percent) were similar (p=0.7). In contrast, a significant difference in cure rate was observed when groups T1N0 and T2aN0 (83 percent) were compared to subgroups T2bN0 tumors are similar and should be submitted to the sametreatment. T2bN0 tumors present a high rate of local and regional recurrence and should therefore be submitted to more aggressive treatment

Quatro dos pacientes com doença hidática policística por nós observados referiam ter reconhecido doença no fígado de pacas caçadas a fim de serem utilizadas como alimento; as vísceras dessea animais eram, habitualmente, dadas aos cäes domésticos. Todos os nossos 7 pacientes referiam contactos com cäes que previamente haviam ingerido vísceras de pacas. O exame do fígado considerado doente por um dos pacientes e retirado de uma paca abatida na mesma regiäo (Estado do Acre, Brasil) de onde provieram os casos humanos mostrou a presença de cistos hidáticos. As características dos acúleos do protoscolex indicaram tratar-se da forma larval do Eschinococcus vogeli. Essas observaçöes confirmam a participaçäo da paca no ciclo biológico do E. Vogeli e a via pela qual o homem pode tornar-se hospedeiro intermediário alternativo desse equinococo
