ABSTRACT

El carcinoma indiferenciado con células indiferenciadas tipo osteoclasto (UC-OGC) en cabeza de páncreas, es extremadamente raro. Las características clínicopatológicas, de imagen y la apariencia topográfica no están bien clasificadas. Este reporte de caso describe un paciente con UC-OGC de cabeza de páncreas. Nuestro paciente un adulto mayor de 75 años de edad, presentaba un tiempo de enfermedad considerable, sin sintomatología relevante hasta las etapas avanzadas del tumor, debutando con molestias gástricas someras, luego pérdida de peso. En los exámenes diagnósticos hallaron la presencia de un tumor que comprometía el estómago, duodeno y páncreas. El diagnóstico definitivo lo dio el estudio anatomopatológico. No se dispone de datos clínicos suficientes para un tratamiento que garantice una mayor tasa de supervivencia en los pacientes, sin embargo, la pancreatoduodenectomía es actualmente la alternativa que mejores resultados ofrece, por otra parte, el pronóstico después de la cirugía y la tasa de recurrencia sigue incierto


Undifferentiated carcinoma with undifferentiated osteoclast-like cells (UC-OGC) in the head of the pancreas is extremely rare. The clinicalpathological, imaging and topographic appearance characteristics are not well classified. This case report describes a patient with UC-OGC of the Pancreas Head. Our patient, an adult over 75 years of age, had a considerable illness time, without relevant symptoms until the advanced stages of the tumor, debuting with shallow gastric discomfort, then weight loss. In the diagnostic tests they found the presence of a tumor that compromised the stomach, duodenum and pancreas. The definitive diagnosis was given by the pathological study. There are not enough clinical data available for a treatment that guarantees a higher survival rate in patients, however, pancreatoduodenectomy is currently the alternative that offers the best results, on the other hand, the prognosis after surgery and the recurrence rate still uncertain.

ABSTRACT

O carcinoma de nasofaringe é neoplasia rara, com incidência maior em países do Sudeste Asiático. OBJETIVO: Avaliar dados demográficos, clínicos, terapêuticos e prognósticos do carcinoma indiferenciado de nasofaringe em um serviço de referência. CASUÍSTICA E MÉTODO: Estudo retrospectivo de 46 pacientes, de janeiro de 1978 a agosto de 2000. Nenhum paciente foi previamente tratado e não apresentava tumor sincrônico e metástase à distância. RESULTADOS: A idade variou de 14 a 78 anos (média, 46), sendo 35 (76 por cento) pacientes masculinos. Todos eram de etnia caucasiana ou afro-brasileira. O tempo de história variou de 1 a 48 meses (média, 7), sendo 47 por cento tabagistas e 33 por cento etilistas. O sintoma mais relatado foi a presença de nódulo no pescoço (34 pacientes). Quanto ao estadiamento clínico, 22 foram estadiados como T1/T2 e 24 como T3/T4, enquanto 24 foram classificados como N2 e 16, N3. O tratamento instituído com finalidade curativa foi a radioterapia, associada à quimioterapia concomitante nos estádios III e IV. Dos 27 pacientes com seguimento após o tratamento inicial, 52 por cento apresentavam-se vivos e livres de doença há três anos. CONCLUSÃO: Os pacientes eram de estádio clínico avançado, com sobrevida livre de doença em três anos de 52 por cento.


The nasopharyngeal carcinoma (NPC) is a rare cancer with a high incidence in Southern Asia. AIM: to study the demographic, clinical, therapeutic, and prognostic factors of nasopharyngeal undifferentiated carcinoma in a reference service. MATERIALS AND METHODS: A retrospective study was made of 46 patients from January 1998 to August 2000. The patients had no previous treatment and did not present any evidence of synchronous tumors or distance metastases. RESULTS: The age ranged from 14 to 78 years (mean = 46 years); 35 (76 percent) patients were male. All patients were Caucasian or African-Brazilian. The onset of initial symptoms ranged from 1 to 48 months (mean = 7 months); 47 percent of the subjects smoked tobacco and 33 percent consumed alcoholic beverages. A lump in the neck was the most frequent symptom (34 patients). Twenty-two patients were clinically staged as T1/T2 and 24 patients as T3/T4; 24 patients were classified as N2, and 16 patients were staged as N3. Curative treatment consisted of radiotherapy and simultaneous chemotherapy in clinical stages III and IV. Of 27 patients that were monitored, 52 percent were alive with no evidence of disease after three years. CONCLUSION: All patients were in advanced clinical stages of the disease. The three-year disease-free survival rate was 52 percent.
