Patients with incurable esophageal cancer (EC) or pancreaticobiliary cancer (PBC) often have multiple symptoms and their quality of life is poor. We investigated which problems these patients experience and how often care is expected for these problems to provide optimal professional care. Fifty-seven patients with incurable EC (N = 24) or PBC (N = 33) from our outpatient clinic completed the validated "Problems and Needs for Palliative Care" (PNPC) questionnaire and two disease-specific quality of life questionnaires, European Organization for Research and Treatment in Cancer (EORTC). Although patients in general had several problems, physical, emotional, and loss of autonomy (LOA) problems were most common. For these physical and emotional problems, patients also expected professional care, although to a lesser extent for LOA problems. Inadequate care was received for fatigue, fear, frustration, and uncertainty. We conclude that an individualized approach based on problems related to physical, emotional, and LOA issues and anticipated problems with healthcare providers has priority in the follow-up policy of patients with incurable upper gastrointestinal cancer. Caregivers should be alert to discuss needs for fatigue, feelings of fear, frustration, and uncertainty.

Up to a quarter of polyps and adenomas are missed during colonoscopy due to poor visualization behind folds and the inner curves of flexures, and the presence of flat lesions that are difficult to detect. These numbers may however be conservative because they mainly come from back-to-back studies performed with standard colonoscopes, which are unable to visualize the entire mucosal surface. In the past several years, new endoscopic techniques have been introduced to improve the detection of polyps and adenomas. The introduction of high definition colonoscopes and visual image enhancement technologies have been suggested to lead to better recognition of flat and small lesions, but the absolute increase in diagnostic yield seems limited. Cap assisted colonoscopy and water-exchange colonoscopy are methods to facilitate cecal intubation and increase patients comfort, but show only a marginal or no benefit on polyp and adenoma detection. Retroflexion is routinely used in the rectum for the inspection of the dentate line, but withdrawal in retroflexion in the colon is in general not recommended due to the risk of perforation. In contrast, colonoscopy with the Third-Eye Retroscope® may result in considerable lower miss rates compared to standard colonoscopy, but this technique is not practical in case of polypectomy and is more time consuming. The recently introduced Full Spectrum Endoscopy™ colonoscopes maintains the technical capabilities of standard colonoscopes and provides a much wider view of 330 degrees compared to the 170 degrees with standard colonoscopes. Remarkable lower adenoma miss rates with this new technique were recently demonstrated in the first randomized study. Nonetheless, more studies are required to determine the exact additional diagnostic yield in clinical practice. Optimizing the efficacy of colorectal cancer screening and surveillance requires high definition colonoscopes with improved virtual chromoendoscopy technology that visualize the whole colon mucosa while maintaining optimal washing, suction and therapeutic capabilities, and keeping the procedural time as low and patient discomfort as optimal as possible.

Primary liver cancer is the sixth most common cancer in the world and the third cause of cancer-related death. Hepatocellular carcinoma (HCC) represents more than 90% of primary liver cancers and generally occurs in patients with underlying chronic liver disease such as viral hepatitis, hemochromatosis, primary biliary cirrhosis and non-alcoholic steatohepatitis. Especially cirrhotic patients are at risk of HCC and regular surveillance could enable early detection and therapy, with potentially improved outcome. We here summarize existing evidence for surveillance including ultrasound, other radiological modalities and various serum biomarkers, and current international guideline recommendations for surveillance. Ultrasound and α-fetoprotein (alone or in combination) are most frequently used for surveillance, but their sensitivities and specificities are still far from perfect, and evidence for surveillance remains weak and controversial. Various other potential surveillance tools have been tested, including serum markers as des-carboxyprothrombin, lectin-bound α-fetoprotein, and (most recently) circulating TIE2-expressing monocytes, and radiological investigations such as computed tomography-scan or magnetic resonance imaging-scan. Although early results appear promising, these tools have generally been tested in diagnostic rather than surveillance setting, and in most cases, no detailed information is available on their cost-effectiveness. For the near future, it remains important to define those patients with highest risk of HCC and most benefit from surveillance, and to restrict surveillance to these categories.
