ABSTRACT
Los pacientes con cáncer avanzado y recurrente de la piel de la cabeza y el cuello requieren agresivos y prolongados procedimientos, además de padecer una elevada morbilidad, para alcanzar márgenes seguros de curación oncológica. Se trataron once pacientes, 7 con carcinomas de células escamosas, 3 con carcinomas de células basales y 1 Schwanoma maligno, con una combinación de craniotomía, cirugía basal craneal y abordaje craneofacial para reconstruir extensos defectos utilizando colgajos libres musculares y cutáneos en una intervención. Grasa, músculo y 1 mm de una capa epidural de un adhesivo biológico (Bioglue) se usaron para sellar suturas durales y obliterar potenciales espacios muertos. No hubo reacciones adversas al adhesivo biológico y ningún paciente presentó otras complicaciones. De los once pacientes, 3 fallecieron por complicaciones médicas: embolismo pulmonar, mielodisplasia tardía e infarto del miocardio. Para el momento de nuestro seguimiento (9-58 meses) ningún paciente ha presentado recurrencias o metástasis distales
Patients with advanced and recurrent head and neck skin cancer need aggressive and prolonged reconstructive procedures, besides suffering high morbidity, to get safe margins of oncology healing. We treated eleven patients, 7 with squamous cell carcinomas, 3 with basal cell carcinomas and 1 malignant Schwanoma, by a combination of craniotomy, basal cranium, surgery and cra-niofacial boarding to reconstruct extensive defects using free muscular and skin flaps in one intervention. Fat, muscle and 1 mm ipidural biological adhesive layer (Bioglue) was used to seal dural sutures and obliterate potential dead spaces. There were no adverse reactions to the biological adhesive and no patients presented other complications. Out of the eleven patients 3 died due to medical complications: lung embolism, late mielodisplasia and myocardial infarction. After 9-58 months follow up none of the patients have presented with recurrent or distal metastasis

Se trata de un estudio de prevalencia de las defunciones por tumores malignos del oído, nariz y garganta en Chile, durante el decenio 1982 a 1991, que alcanzaron a 1.850, con una tasa de prevalencia global de 14.9 por 100.000 habitantes, 24.5 por 100.000 varones y 5.5 por 100.000 damas. El Riesgo Relativo del varón es de 4.5 por cada dama fallecida. La localización laríngea es la más frecuente con 1.093 defucniones y una tasa de mortalidad de 8.8 por 100.000 habitantes, 15.3 por 100.000 varones y 2.5 por 100.000 damas, con un Riesgo Relativo de 6.1 varones por cada dama. Las defunciones por estas causas corresponden en 0.4 por ciento a los niños; 95 por ciento se produce después de los 45 años con tasas ascendentes con la edad. Los diagnósticos histológicos, en su gran mayoría, corresponden a neoplasias espino-celulares con diferentes grados de diferenciación

The clinicopathologic and immunohistochemical finding of 10 cases of nasal non-Hodgkin's lymphoma (NHL) and 23 cases of Waldeyer's ring NHL were studied. Immunohistochemically, nasal NHL expressed T-cell markers exclusively, whereas the NHL of Waldeyer's ring were of both T-cell (56.5%) and B-cell lineages (43.5%). Angioinvasiveness by tumor cells was exclusively noted in the T-lineage lymphomas. Epithelial hyperplasia, epitheliotropism by tumor cells, and extensive invasion of adjacent normal tissue were more prominent in T-cell lymphomas than in B-cell lymphomas. T-lineage lymphomas showed distant extranodal spread pattern involving the skin, soft tissue, stomach, spleen, and the liver, whereas B-lineage lymphomas tended to localize in the lymph nodes. The survival rate of Nasal NHL was similar to that of Waldeyer's ring NHL. Although not statistically significant because of small sample numbers, immunophenotype, histologic groups of monomorphic lymphoma, and stage had prognostic importance. In general, T-lineage lymphomas presented with a higher stage than B-lineage lymphomas (p < 0.05)-and overall survival was poor. Stage I disease showed a much more favorable prognosis than stage II disease. Monomorphic lymphomas had a shorter survival than polymorphic reticulosis (PR) or lymphomas with features of PR. This result in conjunction with the morphologic transition between them suggested that monomorphic lymphoma may represent the most advanced stage in the spectrum of PR, lymphoma with features of PR, and monomorphic lymphoma.
