Proton Therapy Results in the Treatment of Hepatocellular Carcinoma According to the Barcelona-Clinic Liver Cancer (BCLC) Staging System

引用

International Journal of Medical Physics, Clinical Engineering and Radiation Oncology 2015年第2期4卷 96-103页

作者： Francesco dionisi Maurizio Amichetti Protontherapy Unit Department of Oncology Azienda Provinciale per i Servizi Sanitari Trento Italy

Proton therapy represents the most advanced form of radiotherapy currently available. Hepato-cellular carcinoma (HCC) has been extensively treated with proton therapy since 1983 with en-couraging results in terms of effectiveness and safety, as reported in recent research articles, systematic reviews and meta-analyses. In this report, we summarized for the first time the results of proton therapy treatment for HCC according with respect to the Barcelona Clinic Liver Cancer Staging System, the most adopted classification system for HCC which provides information on both prognostic prediction and treatment allocation.

In this report,we present a case of advanced squamous cell cancer located in the rectum of a 78-year-old woman treated with chemoradiation with curative *** patient showed a complete clinical response to chemoradiation;multiple biopsies were performed at the site of the previous mass 5 mo after the end of treatment and histological examination showed no residual tumour in the *** intervention was avoided and the patient was free of disease 12 mo after the diagnosis of *** chemoradiation should be considered as the treatment of choice for this rare malignancy.
