BACKGROUND Circulating tumour cells (CTC) in the blood have been accepted as a prognostic marker in patients with metastatic colorectal cancer (CRC). Only limited data exist on the prognostic impact of CTC in patients with early stage CRC using standardised detection assays. The aim of this study was to elucidate the role of CTC in patients with(More)
Currently, it remains unclear, if patients with colon cancer and synchronous unresectable metastases who present without severe symptoms should undergo resection of the primary tumour prior to systemic chemotherapy. Resection of the primary tumour may be associated with significant morbidity and delays the beginning of chemotherapy. However, it may prevent(More)
PURPOSE Up to 25% of patients with node-negative colorectal cancer (CRC) on conventional histopathologic analysis ultimately die of recurrent disease. We performed a systematic review with meta-analyses to clarify whether molecular detection of isolated tumor cells or micrometastases in regional lymph nodes indicates high risk of disease recurrence and poor(More)
The prognosis of colorectal cancer (CRC) is closely linked to the occurrence of distant metastases, which putatively develop from circulating tumor cells (CTCs) shed into circulation by the tumor. As far more CTCs are shed than eventually metastases develop, only a small subfraction of CTCs harbor full tumorigenic potential. The aim of this study was to(More)
BACKGROUND Although neoadjuvant radiotherapy may improve local control of rectal cancer, its clinical value requires further evaluation as a result of potential side effects and advances in surgical technique. A meta-analysis was performed to assess effectiveness and safety of neoadjuvant radiotherapy in the management of rectal cancer. METHODS The(More)
The prognosis of colorectal cancer is closely linked to the occurrence of distant metastases. Systemic dissemination is most likely caused by circulating tumor cells (CTC). Despite the fundamental role of CTC within the metastatic cascade, technical obstacles have so far prevented detailed genomic and, in particular, phenotypic analyses of CTC, which may(More)
BACKGROUND The prognostic role of circulating tumor cells (CTCs) has been established for colorectal cancer (CRC). We investigated the qualitative and quantitative detection of CTC in the central (CVBC) and mesenteric (MVBC) venous blood compartments to elucidate the patterns of hematogenous tumor cell dissemination in patients with CRC. METHODS A total(More)
BACKGROUND Postoperative ileus is a common problem after abdominal surgery. It was postulated that coffee intake would decrease postoperative ileus after colectomy. METHODS This was a multicentre parallel open-label randomized trial. Patients with malignant or benign disease undergoing elective open or laparoscopic colectomy were assigned randomly before(More)
Although blood group 0 is associated with a reduced risk of pancreatic cancer, little is known about the role of AB0 blood group antigens in disease progression. We assessed the prognostic relevance of AB0 blood status in a large cohort of patients with resected pancreatic cancer. A total of 627 patients, who underwent resection for pancreatic ductal(More)
BACKGROUND Advances in neoadjuvant therapy enabled novel strategies for treating resectable and initially unresectable colorectal cancer liver metastases. Although it is well known that chemotherapeutic agents cause certain types of liver parenchymal injury, the actual contribution of chemotherapy-associated hepatotoxicity to postoperative morbidity remains(More)
