Clinicopathological and prognostic significance of androgen receptor overexpression in colorectal cancer. Experience from Al-Madinah Al-Munawarah, Saudi Arabia.

Clinicopathological and prognostic significance of androgen receptor overexpression in colorectal cancer. Experience from Al-Madinah Al-Munawarah, Saudi Arabia. Saudi Med J. 2019 Sep;40(9):893-900 Authors: Albasri AM, Elkablawy MA Abstract OBJECTIVES: To examine the androgen receptor (AR) status in colorectal cancer (CRC) patients by the immunohistochemical method and to correlate the findings with all available clinicopathological parameters of prognostic significance. METHODS: Archival tumor samples were studied using immunohistochemistry for AR expression in 324 patients with CRC. Patients were diagnosed at the Pathology Department at a tertiary care Hospital, Al-Madinah Al-Munawarah, Saudi Arabia, between January 2006 and December 2017. RESULTS: There is a complete lack of AR expression in normal colonic mucosa; however, AR was expressed in 16 cases (40%) of colorectal adenoma. In CRC, AR expression was high in 118 cases (36.4%). There were no significant correlations between AR expression and gender, age, tumor histologic type, and tumor location. However, AR expression revealed a significant correlation with tumor size (p=0.026), tumor differentiation (p=0.047), American Joint Committee on Cancer (AJCC)  staging (p=0.043), lymph node positivity (p=0.018), lymphovascular invasion (p=0.018), and distant metastasis (p=0.049). In univariate Kaplan-Meier survival analysis, there was a significant (p=0.002) difference in overall survival betw...

ConclusionThe better prognosis in young patients is presumably due to their better physiological reserve and lower incidence of comorbidities. Efforts should be made in younger patients to diagnose early and treat aggressively.

WheelerAbstractColorectal cancer (CRC) can be effectively prevented or detected with guideline concordant screening, yet Medicaid enrollees experience disparities. We used microsimulation to project CRC screening patterns, CRC cases averted, and life-years gained in the population of 68,077 Oregon Medicaid enrollees 50–64 over a five year period s...

Objectives: We aimed to examine whether the improved outcome of a digestive cancer procedure in high-volume hospitals is specific or correlates with that of other digestive cancer procedures, and determine if the discriminant cut-off of hospital volume may influence postoperative mortality (POM) regardless of the procedure. Background: Performing complex surgeries in tertiary centers is associated with improved outcome. However, the association between POM and hospital volume of nonspecific procedures is unknown. Methods: Patients who underwent colectomy, proctectomy, esophagectomy, gastrectomy, pancreatectomy, and...

Objective: The aim of this study was to assess the effect of cancer-related genes and their mutations analyzed by next-generation sequencing (NGS) on the oncological outcome after resection of colorectal liver metastases (CRLM). Background: Traditional prognostic scores include clinical and pathological parameters of primary tumor and metastases. The modified clinical risk score (m-CS), based on size of metastases, primary tumor nodal status, and RAS mutation status outperformed traditional scores. We hypothesized to further improve the scoring system based on the results of NGS. Methods: Cancer tissues of 139 pati...

Conclusions: This study presents the largest reported population-based analysis of liver resection rates in colorectal cancer patients. Significant variation has been observed in patient and hospital characteristics and the likelihood of patients receiving a liver resection, with the data showing that proximity to a liver resection service is as important a factor as deprivation.

The sequence of events leading to the development of colorectal cancer, currently the third most common malignancy in Western countries, is effectively disrupted by the resection of its precursor lesions. Colonoscopy is the mainstay in lesion detection, and endoscopic polypectomy is the conventional therapeutic response for the overwhelming majority of identified polyps. Approximately 2% of lesions are larger (>20  mm) and are laterally spreading lesions (LSLs). EMR is considered the standard of care for the majority of these because it has been proved to be safer, less resource-intensive, and less expensive than surgery.

Authors: Zeng X, Liu Q, Yang Y, Jia W, Li S, He D, Ma R Abstract Placenta-specific protein 8 (PLAC8) is a conserved protein with a molecular weight of 12.5 kDa. The specific function of this protein has not been fully elucidated, however, PLAC8 has been found to play an important tumor regulatory role in certain types of cancer, including colon, pancreatic and liver cancer. PLAC8 also participates in the regulation of the cell cycle, autophagy, epithelial-mesenchymal transition and other cellular functions, indicating its potential as a molecular target worth further investigation. The present study investigated th...

However, few studies describe a correlation between T3 subdivision and prognosis in colon cancer. The current study aimed validate the correlation between the invasion distance (ID) beyond the muscularis propria and prognosis in colorectal cancer. The present retrospective study included 148 consecutive patients with pathologically confirmed T3 colorectal cancer, who underwent resection between January 2008 an...

Authors: Wang Y, Zhang B, Gao G, Zhang Y, Xia Q Abstract Guanine nucleotide exchange factor T (GEFT), a member of the Rho guanine nucleotide exchange factor family, is expressed in a variety of tumors. In the present study, the expression and clinical significance of GEFT in malignant digestive tract tumors was assessed. Tumor and adjacent control samples from 180 patients were tested. Positive GEFT expression rates were 80, 83.33 and 86.67% in esophageal squamous carcinoma (ESCC), gastric carcinoma (GC) and colorectal cancer (CRC), respectively. GEFT expression was associated with diffuse type carcinoma according ...
