[Donors yesterday and today: have the characteristics of liver donors changed over the last 15 years?]. / Donantes de ayer y de hoy: han cambiado las características de los donantes de hígado durante los últimos 15 años?

INTRODUCTION: The social, medical and demographic changes of our population and the increase in the number of patients on waiting lists have led to some changes in the selection criteria of organ donors. MATERIAL AND METHOD: A retrospective, descriptive and comparative study of the liver cadaveric donors features accepted in the Liver Transplant Unit in La Fe University Hospital of Valencia (Spain) in 2 different periods. We distributed the cases into 2 groups, including in group A the first 200 first donors (from January 1991 to June 1995) and in group B the last 200 donors (from February 2004 to December 2005). RESULTS: The number of donors increased from 18 during 1991 to 106 in 2006. In group A the mean age was 32.4 years, compared to 52.3 years in group B. In group A, the main cause of death was craneoencephalic traumatism and in group B cerebrovascular accidents. The mean time in the intensive care unit was longer in the second group with 67.2 hours. In group B, considerable atherosclerosis was reported in 17% of cadaveric donors and macroscopic liver steatosis in 29.5%, compared to 5 and 12%, respectively, in group A. CONCLUSIONS: Nowadays, cadaveric liver donors are older, suffer more chronic diseases, die due to cerbrovascular diseases, remain longer in intensive care units and the livers are macroscopically worse compared to donors accepted 15 years ago.

Sarcoma indiferenciado (embrionario) de hígado del adulto: informe de un caso y revisión de la literatura médica / Hepatic undifferentiated (embryonal) sarcoma in an adult: a case report and literature review

El sarcoma indiferenciado (embrionario) de hígado (SIH) es un tumor hepático maligno que en raras ocasiones afecta al adulto. Presentamos el caso de un varón de 40 años de edad con SIH, tratado con cirugía y quimioterapia basada en iofosfamida y adriamicina con buenos resultados. Según nuestros datos, sólo hay 70 casos publicados en la literatura médica de pacientes adultos con SIH desde que se definió esta entidad clinicopatológica. En general, los pacientes tratados con cirugía asociada a quimioterapia obtuvieron mejores resultados que los sometidos únicamente a cirugía, si bien el pronóstico de este tipo de tumores sigue siendo poco esperanzador

Undifferentiated (embryonal) sarcoma of the liver (USL) is a rare malignant hepatic tumor in adults. We report the case of a 40-year-old man with USL who was successfully treated with surgical resection and chemotherapy using ifosfamide and adriamycin. To our knowledge, only 70 cases of USL in adults have been reported worldwide in the 40 years since this clinicopathological entity was defined. Although the prognosis of the disease remains generally poor, long term survival has been achieved in patients with a combination of surgery and chemotherapy

[Reflections on 250 interventions for colorectal carcinoma metastases to the liver]. / Reflexiones sobre 250 intervenciones de metástasis hepáticas de carcinoma colorrectal.

INTRODUCTION: The best results in the treatment of colorectal cancer metastases to the liver are currently achieved with surgical resection performed under high quality standards. OBJECTIVES. To analyze the results and quality standards of the surgical treatment of colorectal cancer liver metastases in a referral liver unit over an 11-year period. PATIENTS AND METHOD: From January 1995 to December 2005, 250 surgical interventions were performed in 221 patients diagnosed with colorectal cancer liver metastases, resulting in 201 hepatic resections. RESULTS: Nineteen percent of patients were >/= 70 years old and comorbidity was present in 54%. Of the 201 hepatic resections, 8.5% were second resections. Major hepatectomy was performed in 39% of the patients. R0 resection was achieved in 85% of the patients. Blood transfusions were not required in 80% of the patients. The median length of postoperative stay was 6 days. Postoperative mortality was nil and morbidity was 19%. Morbidity was associated with the number of resected segments and the need for blood transfusion. The estimated 1-, 3- and 5-year cumulative survival rates were 96%, 69% and 52%, respectively, while estimated disease-free survival rates were 58%, 32% and 24%, respectively. CONCLUSIONS: Resection of colorectal cancer liver metastases is an effective therapeutic alternative if high current quality standards are achieved.
