Today, hepatocellular carcinoma (HCC) represents the leading cause of death in patients with liver cirrhosis; in most western countries the incidence is also expected to increase further. Due to insufficient surveillance of patients at risk, most cases are diagnosed in an intermediate to advanced stage, leading-together with the underlying liver cirrhosis-to limited therapeutic options and a dismal prognosis. Therefore, classification according to stage and interdisciplinary treatment decisions in experienced centers are of paramount importance to provide an individualized treatment plan when considering potentially curative (resection, liver transplantation, local ablation) and palliative (transarterial approaches, sorafenib) treatment options. There is hope that the prognosis of patients with HCC can be improved in the near future by better prevention, stringent surveillance, multimodality treatment approaches, and an expansion of personalized medicine.

From a global perspective, gastric cancer including adenocarcinoma of the esophagogastric junction is the fourth most common malignant tumor and the second most common cause of cancer-related death. Due to the lack of specific symptoms of early cancer, most gastric cancers are diagnosed in advanced stages. Staging should include high-resolution computed tomography of the thorax, abdomen, and pelvis and documented video-endoscopy and endoscopic ultrasound. ⋯ Combination chemotherapy including a platinum salt plus fluoropyrimidine is the standard of care. About 16 % of gastric cancers exhibit overexpression of the growth factor receptor HER2. Trastuzumab has shown to prolong survival when combined with chemotherapy in HER2-positive gastric cancer.
