Efficacy of the No. 10 lymphadenectomy with spleen preservation on patients with gastric cancer and/or esophagogastric junction adenocarcinoma who underwent total gastrectomy: a systematic review and meta-analysis.

Background: Surgery with total gastrectomy and D2 lymph node dissection (LND) has been recommended as the standard treatment for patients with advanced upper and middle gastric carcinoma and/or Siewert type II/III adenocarcinoma of the esophagogastric junction (AEG). However, whether the No. 10 lymph node (No. 10 LN, also known as splenic hilar LN) should be dissected in total gastrectomy remains controversial. We aimed to evaluate whether the No. 10 LND with spleen preservation has survival benefit for patients with gastric cancer and/or AEG who underwent the total gastrectomy. Methods: The PubMed, Embase, the Cochrane Library, ClinicalTrials.gov and American Society of Clinical Oncology.org (ASCO.org) were electronically searched to identify eligible studies. The primary outcome was the survival rate, and secondary outcomes included the disease-free survival (DFS) rate and side effects. The Review Manager 5.3.5 software was used for the meta-analysis. The odds ratio (OR) and mean difference with 95% confidence interval (CI) were calculated. The statistical heterogeneity was assessed using chi-square (χ2) and I2 tests. Results: Eight studies enrolling a total of 4,131 patients were eligible for our review. The meta-analysis results demonstrated that the No. 10 LND group was significantly better than the non-No. 10 LND group in terms of the 3- (OR =0.71, 95% CI: 0.62-0.81, P<0.00001) and the 5-year (OR =0.66, 95% CI: 0.58-0.75, P<0.00001) survival rates but not in the 1-year survival rate (OR =0.91, 95% CI: 0.75-1.11, P=0.36). The DFS rates in the No. 10 LND group were significantly increased after 1 (OR =0.76, 95% CI: 0.61-0.93, P=0.008), 3 (OR =0.69, 95% CI: 0.60-0.81, P<0.00001), and 5 (OR =0.66, 95% CI: 0.56-0.76, P<0.00001) years compared with those in the non-No. 10 LND group. Discussion: Evidence shows that the No. 10 LND with spleen preservation can improve the survival and the DFS rates for patients with gastric cancer and/or Siewert type II/III AEG who underwent the total gastrectomy. High-quality prospective trials are expected.

NPM1 is a diagnostic and prognostic biomarker associated with the clinicopathological characteristics of gastric cancer.

NPM1 plays an important role in the occurrence and development of leukemia and various solid tumors. This study aimed to investigate the expression of NPM1 in gastric cancer (GC) and adjacent normal tissues, study the relationship between NPM1 expression and clinicopathological characteristics in GC patients, and explore the impact of NPM1 expression on the diagnosis and prognosis of GC. We used tissue microarray immunohistochemical analysis to examine the expression level of NPM1 in GC and adjacent tissues and analyzed the relationship between NPM1 expression, clinicopathological factors, and GC prognosis. Prognostic values of NPM1 mRNA were also investigated using an online database. qRT-PCR was used to detect the expression of NPM1 mRNA in cancer and adjacent tissues. According to microarray immunohistochemical analysis and qRT-PCR results, NPM1 had a high expression in all adjacent normal tissues. Microarray immunohistochemical analyses demonstrated that the NPM1 was lowly expressed in 75.5% of GC tissues but highly expressed in 24.5% of GC tissues. qRT-PCR results showed NPM1 mRNA low expression in most GC tissues. NPM1 high expression group was associated with a better overall survival rate and disease-free survival rate than the NPM1 low expression group (p<0.01). This result is consistent with that of the online database. The receiver operating characteristics curve showed that NPM1 was valuable in the diagnosis of GC. The assessment of NPM1 expression in GC samples may represent a useful tool for GC diagnosis and prognosis assessment.

Esmolol inhibits inflammation and apoptosis in the intestinal tissue via the overexpression of NF-κB-p65 in the early stage sepsis rats.

BACKGROUND/AIMS: Accumulating evidence reveals esmolol could protect the gut mucosa through the regulation of immune response and inflammation in patients with sepsis. However, its underlying mechanism is not fully understood. MATERIALS AND METHODS: Diamine oxidase (DAO), intestinal fatty acid-binding protein (I-FABP), interleukin (IL)-6, and IL-10 in the plasma of rats were detected by ELISA assay. Western blotting was utilized to measure the expression levels of NF-kappa B-p65, Bcl-2, and cleaved caspase-3 in the intestinal tissues. The survival analysis was performed in each group. RESULTS: The plasma levels of DAO and IL-10 levels were increased, whereas that of I-FABP and IL-6 were decreased in the sepsis rats after esmolol treatment, indicating that after the esmolol treatment, the intestinal inflammation and damages were remarkably reduced as compared to those in the normal saline treated sepsis rats. NF-κB-p65 and Bcl-2 were highly expressed, but cleaved caspase-3 showed lower expression in the esmolol treated groups. However, at the same time, we observed contrasting results in the normal saline treated group. Western blotting data indicated that the esmolol treatment inhibited the inflammation and apoptosis in the intestinal tissue due to the overexpression of NF-κB-p65 in the celiac sepsis rats. The survival analysis results indicate that the esmolol infusion should be used in the early stages sepsis rats. CONCLUSION: Esmolol can suppress inflammation and apoptosis in the intestinal tissue via the overexpression of NF-kappa B-p65 in the early stage sepsis rats. kappa BEarly-stage use of esmolol might be an ideal treatment method for sepsis.

Esophageal tuberculosis complicated with intestinal tuberculosis: A case report.

BACKGROUND: Although the overall incidence of tuberculosis in underdeveloped areas has increased in recent years, esophageal tuberculosis (ET) is still rare. Intestinal tuberculosis (ITB) is relatively more common, but there are few reports of ET complicated with ITB. We report a case of secondary ET complicated with ITB in a previously healthy patient. CASE SUMMARY: A 27-year-old female was hospitalized for progressive dysphagia, retrosternal pain, acid regurgitation, belching, heartburn, and nausea. Upper gastrointestinal endoscopy showed a mid-esophageal ulcerative hyperplastic lesion. Endoscopic ultrasonography showed a homogeneous hypoechoic lesion, with adjacent enlarged lymph nodes. Biopsy histopathology showed inflammatory exudation, exfoliated epithelial cells and interstitial granulation tissue proliferation. Colonoscopy revealed a rat-bite ulcer in the terminal ileum and a superficial ulcer in the ascending colon, near the ileocecal region. The ileum lesion biopsy showed focal granulomas with caseous necrosis. Polymerase chain reaction for Mycobacterium tuberculosis was positive in the esophageal and ileum lesion biopsies. The T-cell spot tuberculosis test was also positive. The patient was diagnosed with secondary ET infiltrated by mediastinal lymphadenopathy and complicated with ITB, possibly from the Mycobacterium tuberculosis-infected esophageal lesion. After 2 mo of anti-tuberculosis therapy, her symptoms improved significantly, and upper gastrointestinal endoscopy showed healing ulcers. CONCLUSION: When dysphagia or odynophagia occurs in patients at high-risk for tuberculosis, ET should be considered.
