| 1 | challenges of advanced hepatocellular carcinoma显示文摘Hepatocellular carcinoma(HCC) is an aggressive malignancy,resulting as the third cause of death by cancer each year. The management of patients with HCC is complex,as both the tumour stage and any underlying liver disease must be considered conjointly. Although surveillance by imaging,clinical and biochemical parameters is routinely performed,a lot of patients suffering from cirrhosis have an advanced stage HCC at the first diagnosis. Advanced stage HCC includes heterogeneous groups of patients with different clinical condition and radiological features and sorafenib is the only approved treatment according to Barcelona Clinic Liver Cancer. Since the introduction of sorafenib in clinical practice,several phase Ⅲ clinical trials have failed to demonstrate any superiority over sorafenib in the frontline setting. Locoregional therapies have also been tested as first line treatment,but their role in advanced HCC is still matter of debate. No single agent or combination therapies have been shown to impact outcomes after sorafenib failure. Therefore this review will focus on the range of experimental therapeutics for patients with advanced HCC and highlights the successes and failures of these treatments as well as areas for future development. Specifics such as dose limiting toxicity and safety profile in patients with liver dysfunction related to the underlying chronic liver disease should be considered when developing therapies in HCC. Finally,robust validated and reproducible surrogate end-points as well as predictive biomarkers should be defined in future randomized trials. | Stefano Colagrande Andrea L Inghilesi Sami Aburas Gian G Taliani Cosimo Nardi Fabio Marra | 2016 | World Journal of Gastroenterology2016，22，34： | 19 |
| 2 | Advanced hepatocellular carcinoma and sorafenib: Diagnosis, indications, clinical and radiological follow-up显示文摘Advanced stage hepatocellular carcinoma(HCC) is a category of disease defined by radiological, clinical and hepatic function parameters, comprehending a wide range of patients with different general conditions. The main therapeutic option is represented by sorafenibtreatment, a multi-kinase inhibitor with anti-proliferative and anti-angiogenic effect. Trans-arterial Radio Embolization also represents a promising new approach to intermediate/advanced HCC. Post-marketing clinical studies showed that only a portion of patients actually benefits from sorafenib treatment, and an even smaller percentage of patients treated shows partial/complete response on follow-up examinations, up against relevant costs and an incidence of drug related adverse effects. Although the treatment with sorafenib has shown a significant increase in mean overall survival in different studies, only a part of patients actually shows real benefits, while the incidence of drug related significant adverse effects and the economic costs are relatively high. Moreover, only a small percentage of patients also shows a response in terms of lesion dimensions reduction. Being able to properly differentiate patients who are responding to the therapy from non-responders as early as possible is then still difficult and could be a pivotal challenge for the future; in fact it could spare several patients a therapy often difficult to bear, directing them to other second line treatments(many of which are at the moment still under investigation). For this reason, some supplemental criteria to be added to the standard modified Response Evaluation Criteria in Solid Tumors evaluation are being searched for. In particular, finding some parameters(cellular density, perfusion grade and enhancement rate) able to predict the sensitivity of the lesions to anti-angiogenic agents could help in stratifying patients in terms of treatment responsiveness before the beginning of the therapy itself, or in the first weeks of sorafenib treatment. This would bring a strongly desirable help in clinical managements of these patients. | Stefano Colagrande Francesco Regini Gian Giacomo Taliani Cosimo Nardi Andrea Lorenzo Inghilesi | 2015 | World Journal of Hepatology2015，7，8： | 6 |
| 3 | Imaging of the chemotherapy-induced hepatic damage:Yellow liver,blue liver,and pseudocirrhosis显示文摘The liver is the major drug-metabolizing and drug-detoxifying organ.Many drugs can cause liver damage through various mechanisms;however,the liver response to injury includes a relatively narrow spectrum of alterations that,regardless of the cause,are represented by phlogosis,oxidative stress and necrosis.The combination of these alterations mainly results in three radiological findings:vascular alterations,structural changes and metabolic function reduction.Chemotherapy has changed in recent decades in terms of the drugs,protocols and duration,allowing patients a longer life expectancy.As a consequence,we are currently observing an increase in chemotherapy-associated liver injury patterns once considered unusual.Recognizing this form of damage in an early stage is crucial for reconsidering the therapy regimen and thus avoiding severe complications.In this frontier article,we analyze the role of imaging in detecting some of these pathological patterns,such as pseudocirrhosis,“yellow liver”due to chemotherapy-associated steatosis-steatohepatitis,and“blue liver”,including sinusoidal obstruction syndrome,veno-occlusive disease and peliosis. | Linda Calistri Vieri Rastrelli Cosimo Nardi Davide Maraghelli Sofia Vidali Michele Pietragalla Stefano Colagrande | 2021 | World Journal of Gastroenterology2021，27，46： | 2 |
