The current tumor staging system is insufficient for predicting the outcomes of patients with colorectal cancer (CRC) because of its phenotypic and genomic heterogeneity. Integrating gene expression signatures with clinicopathological factors may yield a predictive accuracy exceeding that of the currently available system. Twenty-seven signatures that used gene expression data to predict CRC prognosis were identified and re-analyzed using bioinformatic methods. Next, clinically annotated CRC samples (n=1710) with the corresponding expression profiles, that predicted a patient's probability of cancer recurrence, were pooled to evaluate their prognostic values and establish a clinicopathologic-genomic nomogram...

BACKGROUND AND OBJECTIVES: Clinical experience suggests that cytoreductive surgery (CRS) and hyperthermic intraperitoneal chemotherapy (HIPEC) play an important role in the management of ovarian cancer. In order to improve patient selection, the peritoneal surface disease severity score (PSDSS) was previously introduced for use in colorectal cancer patients. However, almost no data exist regarding the utility of the PSDSS index in ovarian cancer patients. METHODS: A retrospective study of the effectiveness of CRS and HIPEC was carried out in 59 patients with ovarian cancer...

Thioredoxin domain‑containing 5 (TXNDC5) is reportedly overexpressed in colorectal cancer (CRC) and is therefore considered an oncogene. However, the role of TXNDC5 in CRC tumorigenesis remains unclear. The present study aimed to explore the role of TXNDC5 in CRC tumorigenesis in vitro and in vivo under hypoxic and normoxic conditions. Analyses of patient tissue samples revealed a positive association between the expression of hypoxia‑inducible factor‑1α (HIF‑1α) or TXNDC5 and the TNM stage of CRC...

Wangshuo Yang, Yang Wang, Wei Wang, Zhuming Chen, Guang Bai
BACKGROUND The expression of aldehyde dehydrogenase 1A1 (ALDH1A1) is increased in several human tumors, including colorectal carcinoma (CRC). The aim of this study was to compare the expression ALDH1A1 in CRC tumor tissue compared with non-tumor adjacent tissue (NAT), using immunohistochemistry (IHC), and to determine whether the expression of the ALDH1A1 protein was associated with prognostic factors in CRC. MATERIAL AND METHODS Formalin-fixed paraffin-embedded (FFPE) tissue from 424 patients diagnosed with CRC, and 196 matched NATs were used to prepare tissue microarrays (TMAs)...

Olfactomedin-4 (OLFM4, GW112, hGC-1) is a glycoprotein belonging to the olfactomedin family. The expression of OLFM4 is strong in the small intestine, colon and prostate, and moderate in the stomach and bone marrow. Previous studies have revealed that OLFM4 is closely associated with many digestive diseases. Up-regulation of OLFM4 has been detected in the Helicobacter pylori ( H. pylori )-infected gastric mucosa, inflammatory bowel disease tissue and gastrointestinal malignancies, including gastric cancer, colorectal cancer, pancreatic cancer and gallbladder cancer...

Staging is essential for scientific exchanges on colorectal cancer. Lack of a consensual definition for synchronous and metachronous metastases for colorectal cancer may introduce artifactual differences between epidemiological studies according to stage. We investigated how variations in the cutoff for the definition of synchronous metastases influenced the stage-specific distribution and incidence and the survival of stage IV patients. Between 2007 and 2013, a total of 4636 cases of colorectal adenocarcinoma were registered in the cancer registry of Burgundy...

Purpose: Globally, colorectal cancer (CRC) is one of the most common cancers with high mortality. Although CRC patients in stages I-II are curable after surgical resection, due to the lack of sensitive and specific biomarkers, many patients are in the advanced stages when diagnosed. This study aimed to investigate whether circulating miRNAs in plasma could act as biomarkers for early CRC diagnosis. Patients and methods: All healthy subjects and patients were from Nanjing First Hospital...

Background: There is growing interest in the use of stereotactic ablative radiotherapy (SABR) for oligometastases. However, extreme caution should be exercised in treating tumors closely located to organs at risk (OARs) with SABR. To reduce complications, we have applied split-course SABR to oligometastases closely located to OARs or to those being retreated with radiotherapy. Methods: We retrospectively reviewed the records of patients with oligometastases who were treated with planned split-course SABR between January 2012 and December 2016...

BACKGROUND: Colorectal cancer is being diagnosed more frequently in the young and it presents in an advanced stage. In TNM staging, stage depends on tumor size and number of positive nodes, which depend on location of tumor as well as the extent of dissection.The lymph node ratio is regarded as a more reliable marker for prognosis. In this study, we compare epidemiology of colorectal cancer in the young (<40 years) and older patients as well as the LNR. METHODS: Patients with colorectal cancer operated at the Tribhuvan University Teaching Hospital, Kathmandu, Nepal for a period of 4 years (2012 - 2016) were included in the study...
