Colorectal cancer prognosis twenty years later.

AIM: To evaluate changes in colorectal cancer (CRC) survival over the last 20 years. METHODS: We compared two groups of consecutive CRC patients that were prospectively recruited: Group I included 1990 patients diagnosed between 1980 and 1994. Group II included 871 patients diagnosed in 2001. RESULTS: The average follow up time was 21 mo (1-229) for Group I and 50 mo (1-73.4) for Group II. Overall median survival was significantly longer in Group II than in Group I (73 mo vs 25 mo, P < 0.001) and the difference was significant for all tumor stages. Post surgical mortality was 8% for Group Iand 2% for Group II (P < 0.001). Only 17% of GroupI patients received chemotherapy compared with 50% of Group II patients (P < 0.001). CONCLUSION: Survival in colorectal cancer patients has doubled over the past 20 years. This increase seems to be partly due to the generalization in the administration of chemotherapy and to the decrease of post surgical mortality.

Características clinicopatológicas y supervivencia de los pacientes con cáncer de esófago. Resultados de 200 casos consecutivos / Clinicopathological characteristics and survival outcome of esophageal cancer. Results from a series of 200 patients

Fundamento y objetivo: El cáncer de esófago (CE) es una enfermedad poco frecuente pero grave. El objetivo del presente trabajo es describir las características clinicopatológicas y la supervivencia de los pacientes con CE en nuestro hospital. Pacientes y método: Se estudió a 200 pacientes consecutivos diagnosticados o tratados de CE o de la unión gastroesofágica en el Hospital Donostia entre enero del año 2003 y diciembre del año 2007. Se analizó la localización del tumor, el tipo histológico, las pruebas realizadas para establecer el estadio tumoral, los tratamientos utilizados, la supervivencia y la morbimortalidad de la cirugía. Resultados: La ultrasonografía endoscópica (USE) modificó la estrategia terapéutica en un 12% de los pacientes. Un 32% (74) de los pacientes se operaron; de éstos, un 65% (48) recibió radioquimioterapia (RT-QM) neoadyuvante. La supervivencia al año, a los 3 años y a los 5 años fue del 48, el 25 y el 21%, respectivamente. La mortalidad postoperatoria fue del 8% (6 pacientes) y la morbilidad, del 57% (42 pacientes). Los pacientes en estadio III a los que se realizó RT-QM neoadyuvante y cirugía tuvieron un mejor pronóstico que aquéllos a los que sólo se hizo RT-QM (20 meses de supervivencia frente a 9 meses). En el análisis multivariante, los factores de mal pronóstico fueron la localización en el tercio medio (HR [hazard ratio ‘razón de riesgo’]=2,3; intervalo de confianza [IC] del 95%: 1,3–4,1) y la no realización de cirugía tras la RT-QM (HR=1,9; IC del 95%: 1,15–3) (AU)

Background and objective: The esophageal cancer (EC) is a slightly frequent but serious disease. Our aim is to describe the characteristics of the patients with EC in our Hospital. Patients and method: We included 200 patients consecutively diagnosed and/or treated for CE between between January, 2003 and December, 2007. The location of the tumor was analyzed, the histological type, the proofs realized for to establish the classification, the treatments, the survival and the morbi-mortality of the surgery. Results: The endoscopic ultrasonography (EUS) modified the therapeutic strategy in 12% of the patients. The survival to the year, 3 years and 5 years was 48%, 25% and 21%, respectively. 74 (32%) patients were operated, 48 (65%) of them was treated with neoadyuvant chemoradiotherapy. The postsurgical mortality was 8% (6 patients) and the morbidity was 57% (114 patients). In multivariate analysis, after adjustment for traditional risk factors, were the location in the average third ( [HR, hazard ratio]=2.3; confidence interval [IC] of 95%, 1.3–4.1) and not accomplishment of surgery after the chemotherapy and radiotherapy (HR=1.9; IC to 95%, 1.15–3). Conclusions: The diagnosis is realized very later. The EUS has contributed a better therapeutic strategy to our patients. The mortality continues being high (AU)

Littoral-cell angioma of the spleen: a case report.

Littoral-cell angioma (LCA) is a primary splenic vascular tumor that arises from the normal littoral cells lining the sinus channels of the splenic red pulp. We report a case of LCA of the spleen, which has been infrequently communicated in the literature. A 76-year-old man with a 2-wk history of weight loss, abdominal pain and changes in bowel habits was admitted to our hospital. Imaging studies (CT and MRI) showed multiple lesions in the spleen. Splenectomy was performed. Lining cells were positive for CD31/CD68 markers. Our case was associated with a serrated colonic adenoma. LCA is a benign vascular tumor of the spleen that needs to be included in the differential diagnosis of multiple splenic nodules.

Síndrome del glucagonoma y seudoglucagonoma / Glucagonoma and pseudoglucagonoma syndrome

Introducción. El síndrome del glucagonoma puede ser verdadero -asociado a un tumor pancreático secretor de glucagón- o un seudoglucagonoma, asociado a otro tipo de enfermedad. Es una enfermedad extremadamente infrecuente con una prevalencia actual estimada de 1/20.000.000.Material y métodos. Se ha realizado una revisión retrospectiva de casos de glucagonoma y seudoglucagonoma entre enero de 1998 y diciembre de 2003 en 3 hospitales. Se han tratado 5 casos: 3 con tumoración pancreática demostrable y 2 sin neoplasia asociada. Se han analizado la edad, el sexo, el diagnóstico inicial, los síntomas asociados, las enfermedades concomitantes, los procedimientos diagnósticos de imagen empleados, los datos analíticos existentes, los procedimientos terapéuticos empleados, la cirugía y el seguimiento. Resultados. Se encontró hiperglucemia en todos los casos y elevación de valores de glucagón plasmático. En 3 casos había hipoaminoacidemia y descenso de ácidos grasos totales. No se observaron alteraciones de los valores de cinc. La ultrasonografía abdominal no ofreció resultados concluyentes. La tomografía axial computarizada demostró tumoración pancreática en 3 pacientes que fueron intervenidos, por lo que fue posible la resección curativa. El eritema necrolítico migratorio ha sido la clave diagnóstica en todos los casos. La hiperglucagonemia estaba presente en todos ellos. El tratamiento quirúrgico ha sido curativo con seguimientos de 7, 36 y 56 meses en los casos de glucagonoma verdadero. Conclusiones. La prevalencia real del síndrome del glucagonoma puede ser mayor que la estimada actualmente. En nuestra serie ha sido de 13,5/20.000.000 habitantes/año (AU)
