Patients with MSI-High (MSI-H) and MSI-Low (MSI-L) had a longer OS than patients with MSS. MSI was related to CD8 expression but irrelevant to PD-L1 expression.
In Chinese GC patients, MSI frequently occurred in females, patients aged between 59 and 69, and patients with lower clinical stages. Patients with MSI-High (MSI-H) and MSI-Low (MSI-L) had a longer OS than patients with MSS. MSI was related to CD8 expression but irrelevant to PD-L1 expression.
Accurate assessment of lymph node status in gastric cancer (GC) patients can help to select appropriate treatment strategies for GC, but the diagnostic accuracy of conventional methods needs to be improved. The aim of this study was to investigate the predictive value of preoperative hemoglobin and albumin levels and lymphocyte and platelet counts (HALP) on lymph node status in GC patients and to construct a risk prediction model.

This study retrospectively analyzed the clinicopathological characteristics of 349 patients with GC who underwent radical gastrectomy, among which 250 patients were recruited in the training cohort and 99 patients in the independent validation cohort. Significant risk factors in univariate analysis were further identified as independent variables in multivariate logistic regression analysis, which were then incorporated and presented in a nomogram. Receiver operating characteristic (ROC) curves, Calibration curve and decision curve analysis (DCA) curves were used to evaluate the discrimination, prediction accuracy and clinical effectiveness of the model.

Multifactorial logistic regression analysis showed that alcohol use (OR =2.203, P=0.036), Depth of invasion (OR =7.756, P<0.001), differentiation (OR =2.252, P=0.018), carcinoembryonic antigen (CEA) (OR =2.443, P=0.017), carbohydrate antigen 19-9 (CA199) (OR =2.715, P=0.008) and HALP (OR =2.276, P=0.032) were independent risk factors for lymph node metastasis (LNM) in GC. We used these factors to construct a nomogram for predicting LNM in GC patients, and the ROC curves showed good discrimination of the model with AUC values of 0.854 (training cohort) and 0.868 (validation cohort), respectively, and the calibration curves showed good predictive ability of the nomogram, in addition to the DCA curves results showed the clinical usefulness of the model.

In conclusion, we established a nomogram for predicting LNM in patients with GC.

Nivolumab and pembrolizumab are promising therapies for gastric adenocarcinoma. The 22C3 and 28-8 pharmDx immunohistochemistry assays for programmed death ligand-1 scoring criteria have been developed. This study compared the programmed death ligand-1 staining patterns of gastric adenocarcinoma evaluated by the 22C3 and 28-8 pharmDx assays.

Tissue microarray analysis was performed for 226 patients with gastric adenocarcinoma who underwent curative surgery. Interobserver concordance between the 22C3 and 28-8 pharmDx assays was assessed to compare the dichotomized expression values. Programmed death ligand-1 positivity was assessed by combined positive score and tumor proportion score. Immunohistochemistry for deficient mismatch repair proteins and Epstein-Barr virus-encoded RNA
hybridization was examined.

Programmed death ligand-1 positivity with a combined positive score ≥5 was detected in 63 patients (28%) by the 22C3 pharmDx assay, and in 45 patients (20%) by the 28-8 pharmDx assay. A pairwise comp ligand-1 expression levels in gastric adenocarcinoma patients.
Neoadjuvant chemoradiotherapy (nCRT) and surgery are widely used treatments for locally advanced esophageal squamous cell carcinoma (ESCC). Thus, it is critically important to investigate risk factors that affect patient prognosis after preoperative chemoradiotherapy and surgery.

We conducted a retrospective analysis of 77 patients with ESCC who received nCRT and underwent surgery at our center from January 2015 to December 2019. We analyzed the primary clinical data, postoperative pathological results, recurrence, and death results.

Among the 77 ESCC patients who received nCRT and surgery, 19 achieved a postoperative pathologic complete response (pCR), and the overall pCR rate was 24.68%. The univariate analysis indicated that postoperative post-neoadjuvant treatment N stage (ypN) metastasis [hazards ratio (HR) 2.908; 95% confidence interval (CI) 0.874-9.676; P=0.082], a high lymph-node ratio [(LNR) >0.1] (HR 7.149, 95% CI 1.740-29.369; P=0.006), post-neoadjuvant treatment T3-4 (ypT3-4) (HR 3.626, 9 nodes are the most common sites of metastasis in ESCC after nCRT.
0.1) in ESCC patients after nCRT is a risk factor of DSS and RFS. ypN metastasis is also an independent predictor of RFS. Left gastric-arterial lymph nodes, para-cardiac lymph nodes, and left supraclavicular lymph nodes are the most common sites of metastasis in ESCC after nCRT.
This study investigated the predictive value of peripheral inflammatory indices, including neutrophil count, lymphocyte count, platelet count, neutrophil-to-lymphocyte ratio (NLR), and platelet-to-lymphocyte ratio (PLR), in anastomotic leakage during elective esophageal surgery.

This retrospective study included all patients who underwent esophagectomy for esophageal squamous cell carcinoma from 2016 to 2020 in our institution. The peripheral blood inflammatory indices were obtained on preoperative days 1-7 (PRD 1-7), and postoperative days 1-3 (POD 1-3) and 4-7 (POD 4-7). Univariate, multivariate logistic, and receiver operating characteristic curve analyses were conducted to evaluate the diagnostic value of these peripheral blood inflammatory indices.

A total of 198 patients were included in the study, and 25 (13%) patients experienced anastomotic leakage. Multivariate analyses identified diet, neutrophil count, and PLR on POD 1-3, and NLR on POD 4-7 as independent factors associated with anastomotic leakage. Using the receiver operating characteristic curve, the variable with the best area under curve was a neutrophil cutoff count of 4.1 [0.737; 95% CI 0.639-0.835], with a sensitivity and specificity of 60.0% and 66.5%, respectively. This was followed by an NLR cutoff value of 9.5 on POD 4-7 (0.628; 95% CI 0.505-0.752) and a cutoff PLR value of 220.1 on POD 1-3 (0.643; 95% CI 0.536-0.750). Diet showed a poor result on the receiver operating characteristic curve analysis.

Neutrophil count and PLR on POD 1-3 and NLR on POD 4-7 were shown to have predictive value for anastomotic leakage in elective esophageal surgery.

This study aimed to examine the effects of applying the negative pressure wound therapy (NPWT) combined with intermittent instillation (NPWTi) in patients with cervical anastomotic leakage (AL) after esophageal cancer surgery.

From July 2019 to June 2021, 64 patients undergoing AL after esophageal cancer surgery were selected from our Hospital's Thoracic Department, and randomly allocated to the conventional nursing group (20 patients), the hospital central NPWTi group (23 patients), and the portable NPWTi group (21 patients). The hospital central NPWTi group was treated with central negative pressure combined with intermittent instillation, and the portable NPWTi group was treated with portable negative pressure combined with intermittent instillation. Indicators of fistula healing, healing days, treatment costs, comfort, and nursing satisfaction were examined in each group.

The fistula healing rate, healing days, nursing satisfaction, and comfort level of the hospital central NPWTi group and the portaon treatment is worthy of promotion.

F-box protein 45 (FBXO45) is a member of the F-box protein family, and is reportedly involved in the progression of many diseases. However, its role in esophageal cancer (ESCA) remains unclear.

The expression, clinical characteristics, gene function, pathway, and correlation between the infiltration of different immune cells were analyzed using public data. The pan-cancer expression of
was assessed using the TIMER2 database. The expression of
in different tumor stages and histology subtypes were evaluated using the UALCAN database. check details The protein-protein interaction (PPI) network was constructed using the STRING database. Immune cell infiltration data were downloaded from the ImmuCellAI database.

The top 300 genes most positively correlated with
were screened into the enrichment analysis. The functional enrichment results showed that FBXO45 was mainly associated with proteasomal protein catabolic process and the regulation of DNA metabolic processing in the biological process (BP) category; spindle, chromosomal region, and focal adhesion in the cellular component category; and ATPase activity and ubiquitin-protein transferase activity terms in the molecular function category. FBXO45 was overexpressed in ESCA and other cancer types. FBXO45 expression was positively associated with the infiltration levels of immunosuppressive cells, such as CD8
(cluster of differentiation 8+) T cells and NK (natural killer cell) cells, in ESCA. MYCBP2 and SKP1 were most associated with FBXO45.

Our results suggested that FBXO45 is a potential oncogene in ESCA. Elevated FBXO45 expression indicates a relatively immunosuppressive microenvironment.

Gastrointestinal (GI) malignancies represent a heterogeneous group of diseases. Traditional tumor markers, though part of standard-of-care, lack sensitivity and specificity. Tumor-informed circulating tumor DNA (ctDNA) assay-based molecular residual disease assessment as well as recurrence and treatment response monitoring can serve as a robust tool in patients with wide range of GI malignancies and ethnicities.

A personalized, tumor-informed multiplex PCR-NGS assay (Signatera
) was used for the detection and quantification of ctDNA in 258 plasma samples from 198 patients with GI cancers at two institutions. Serial time- points were collected on a subset of patients (n=64) to monitor their ctDNA levels in response to treatment. Chi-square test was used to compare ctDNA-positivity rates in different cohorts.

The study included stage I-IV patients with a median age of 62 years (61% females and 49% ethnic minorities); 92% had surgical resection, 83% received systemic treatment. ctDNA-positivity was significantly associated with advanced stage (P=0.004), and presence/extent of metastases (P<0.00003). Serial time-point analysis showed that 22% (14/64) patients cleared ctDNA following treatment. ctDNA was detected in all patients who recurred (4/4; 100% sensitivity).

Serial monitoring of ctDNA using a tumor-informed ctDNA assay can be prognostic and predictive in advanced GI malignancies in adjuvant setting.
