Potentially curative treatment options for HCC include resection, transplantation, and percutaneous ablation, whereas palliative treatments include trans-arterial chemoembolization(TACE), radioembolization, and systemic treatments. Due to the diversity of available treatment options and patients' presentations, a multidisciplinaryteam should decide clinical management of HCC, according to tumor characteristics and stage of liver disease. Potentially curative treatments are suitable for very-early- and early-stage HCC. However, the vast majority of HCC patients are diagnosed in later stages, where the tumor characteristics or progress of liver disease prevent curative interventions. For patients with intermediate-stage HCC, TACE and radioembolization improve survival and are being evaluated in addition to potentially curative therapies or with systemic targeted therapy. There is currently no effective systemic chemotherapy, immunologic, or hormonal therapy for HCC, and sorafenib is the only approved moleculartargeted treatment for advanced HCC. Other targeted agents are under investigation; trials comparing new agents in combination with sorafenib are ongoing. Combinations of systemic targeted therapies with local treatments are being evaluated for further improvements in HCC patient outcomes. This article provides an updated and comprehensive overview of the current standards and trends in the treatment of HCC.展开更多

As life expectancy constantly increases, the onset of HNC in patients older than 65 years of age at diagnosis is not rare and up to one fourth of cases occurs in patients older that 70 years at age. Because elderly cancer patients are severely under-represented in clinical trials, there is a clear need to address the particular aspects of this specific patient group, especially in the context of novel multidisciplinary therapeutic approaches. The frailty of elderly patients with HNC is attributed to the high incidence of smoking and alcohol abuse in this malignancy and the presence of substantial cardiovascular, respiratory or metabolic comorbidities. In the current work, I provide an overview of current and emerging treatment approaches, in elderly patients with HNC. In particular, I discuss modern surgical approaches that improve radical excision rates while preserving functionality, the incorporation of modern radiotherapeutic techniques and the introduction of novel chemotherapeutic combinations and molecular targeted agents in an effort to reduce toxicity without compromising efficacy. Finally, there is an urgent need to increase accrual and active participation of elderly patients with HNC in clinical trials, including biomarker evaluation in biopsy specimens towards an individualized therapeutic approach.展开更多

The addition of expensive targeted biologic agents to the therapeutic armamentarium against MCRC have not drastically increased survival, particularly in the realm of second and third line patients, as tumor resistance remains an issue. Original approaches to treating MCRC are needed in order to raise the apparent survival ceiling in these patients.展开更多
