PURPOSE Preoperative chemoradiotherapy (CRT) is supposed not only to reduce lymph node metastases but also lymph node recovery in rectal cancer specimens. The objective of this prospective study was to determine the effects of chemoradiation on mesorectal lymph node retrieval under terms of a meticulous histopathological evaluation. METHODS Specimens from(More)
PURPOSE For years, 5-fluorouracil (5-FU) has been the backbone of radiochemotherapy (RCT) of locally advanced rectal cancer. Its main target, thymidylate synthase (TS), is speculated to be an important biomarker for response prediction and long-term prognosis. In this study, we analyzed TS expression in the rectal cancer tissue of 208 patients to evaluate(More)
PURPOSE We evaluated individualized multimodal oncological strategies in patients with bilobular colorectal liver metastases (biCRC-LM) as well as their effect on R0 resection rates, disease-free survival (DFS), and overall survival (OS). METHODS Between January 2001 and December 2008, 64 patients were assigned to straightforward or two-stage liver(More)
BACKGROUND AND AIMS Patients with bilobular colorectal liver metastases (CRLM) experience poor prognosis, especially when curative resection cannot be achieved. However, resectability in these patients is often limited by low future remnant liver volume (FRLV). The latter can be enhanced by a two-stage liver resection, using portal vein ligation to induce(More)
Liver metastasis development in breast cancer patients is common and confers a poor prognosis. So far, the prognostic significance of surgical resection and clinical relevance of biomarker analysis in metastatic tissue have barely been investigated. We previously demonstrated an impact of WNT signaling in breast cancer brain metastasis. This study aimed to(More)
OBJECTIVE In this study, we evaluate the frequency of HER-2 and HER-3 expression in liver metastases from patients with colorectal cancer (CRLM). We analyzed the potential of HER-2 and HER-3 as therapeutic targets and evaluated their prognostic value. PATIENTS AND METHODS Overall 208 patients with CRLM were enrolled. HER-2 and HER-3 expression were(More)
BACKGROUND Ultrasonic scalpel (UC) and monopolar electrocautery (ME) are common tools for soft tissue dissection. However, morphological data on the related tissue alteration are discordant. We developed an automatic device for standardized sample excision and compared quality and depth of morphological changes caused by UC and ME in a pig model. METHODS(More)
PURPOSE Bilobar colorectal liver metastases (CRLM) are often considered incurable or associated with poor prognosis even after R0 resection. In this single-center study, we evaluate the impact of CRLM spreading on recurrence-free survival (RFS) and cancer-specific overall survival (CSS) after R0 resection of CRLM with respect to multimodal treatment(More)
PURPOSE Surgery is the standard of care for resectable colorectal liver metastases (CRC-LM). Unfortunately, 60% of patients develop secondary metastatic recurrence (SMR) after R0-resection of CRC-LM. We investigated the impact of surgical re-intervention and chemotherapy (Ctx) on survival in a consecutive series of patients with SMR. METHODS From 01/2001(More)
Pyloric gland adenoma consists of closely packed pyloric-type glands lined by mucus-secreting cells. To date, approximately 230 cases have been reported, mostly of gastric localization with a tumour size up to 3.5 cm and a mean age of occurrence around 70 years. Adenocarcinoma develops in about 40% of cases and may be difficult to detect due to relatively(More)
