ABSTRACT
BACKGROUND: Transarterial chemoembolisation (TACE), having demonstrated survival benefits, is the treatmentof choice in intermediate-stage hepatocellular carcinoma, although there is great heterogeneity in its clinical application. MATERIAL AND METHODS: A survey was sent to the Madrid Regional hospitals to assess applicability, indications and treatment protocols. The assessment was made overall and according to the type of hospital (groups A vs. B and C). RESULTS: Seventeen out of 22 hospitals responded (8/8 group A, 9/ 14 group B-C). All do/indicate transarterial chemoembolisation, 13/17 at their own facilities. Eight of the 17 hospitals have multidisciplinary groups (5/8 A, 3/9 B-C). Nine hospitals perform > 20 procedures/year (7 group A), and 6 from group B-C request/perform < 10/year. It is performed on an "on-demand" basis in 12/17. In 5 hospitals, all the procedures use drug-eluting beads loaded with doxorubicin. The average number of procedures per patient is 2. The mean time from diagnosis of hepatocellular carcinoma to transarterial chemoembolisation is ≤ 2 months in 16 hospitals. In 11/17 hospitals, response is assessed by computed tomography. Radiological response is measured without specific criteria in 12/17 and the other five hospitals (4 group A) assessed using standardised criteria. CONCLUSION: Uniformity among the Madrid Regional hospitals was found in the indication and treatment regimen. The use of DEB-TACE has become the preferred form of TACE in clinical practice. The differentiating factors for the more specialised hospitals are a larger volume of procedures, decision-making by multidisciplinary committees and assessment of radiological response more likely to be standardised.

Mixed cryoglobulinemia (MC) is a small-vessel systemic vasculitis characterized by the presence of cryoglobulins, immunoglobulin complexes that precipitate at low temperatures ( < 37 ºC) inducing the inflammatory process. The most frequent etiology is hepatitis C infection (HCV) (1). Rituximab (RTX), an anti-CD20 monoclonal antibody, has recently emerged as the treatment of choice for severe MC (2). We present a case of severe hepatitis C virus-induced MC that was controlled and maintained in remission with RTX for 26 months, a remarkable prolonged period of time.

La crioglobulinemia (CG) es una vasculitis sistémica de pequeño vaso caracterizada por la presencia de crioglobulinas, las cuales son inmunocomplejos circulantes que, a bajas temperaturas (< 37 °C), precipitan desencadenando el proceso inflamatorio. La etiología más frecuente es la infección por el virus de la hepatitis C (VHC) (1). En los últimos años el anticuerpo monoclonal anti-CD20 rituximab (RTX) se ha ido posicionando como el tratamiento de primera línea en las CG de presentación agresiva (2). Presentamos el caso de una paciente con brote grave de una CG asociada al VHC que respondió al tratamiento con RTX, manteniéndose posteriormente en remisión de manera inusualmente prolongada durante 26 meses (AU)
