Prognostic impact of family history of cancer in Southern Chinese patients with esophageal squamous cell cancer

Clinical characteristics of early esophageal cancer and squamous intraepithelial neoplasia in patients of different ages

BACKGROUND

In recent years, with the development of endoscopic technology, endoscopic submucosal dissection (ESD) has been widely used in the treatment of early esophageal cancer (EEC) and squamous intraepithelial neoplasia (SIN) because of its low risk of complications and faster recovery. This study focused on evaluating the clinical features of EEC and SIN in elderly patients and the safety of ESD treatment.

AIM

To analyze the clinical characteristics of EEC and SIN in patients of different ages.

METHODS

A total of 349 patients with EEC or SIN (including high- and low-grade intraepithelial neoplasia) treated by endoscopic submucosal dissection (ESD) at the First Affiliated Hospital of Zhengzhou University from January 2019 to October 2022 were included. According to the age at the time of surgery, the patients were divided into either an elderly group (≥ 65 years old) or a young and middle-aged group (< 65 years old), and the general clinical data (gender, smoking status, alcohol consumption, hypertension, diabetes, coronary heart disease, history of other tumors, abdominal surgery history, family history of digestive tract tumor, etc.) and pathological data (lesion location, pathological type, depth of invasion, endoscopic classification, lesion length and diameter, presence of multiple lesions or not, combination with chronic esophagitis, gastric polyps, or atrophic gastritis or not, etc.) were compared between the two groups, and the postoperative related indicators (postoperative hospital stay, postoperative bleeding, esophageal stricture, and resection margin) of the two groups were compared.

RESULTS

The number of patients with hypertension was significantly higher in the elderly group (P = 0.034), while the proportion of patients with smoking history was significantly higher in the middle-aged and young group (P = 0.017). In terms of lesion location, the lesions in the young and middle-aged group were mostly located in the lower thoracic segment, while the lesions in the elderly group were mostly located in the middle thoracic segment (P = 0.005); the lesions in the elderly group were more serious than those in the young and middle-aged group (P = 0.005); and the elderly group had a higher proportion of patients with combined gastric polyps (P = 0.026). In terms of complications and length of hospital stay after ESD, there was no significant difference between the two groups.

CONCLUSION

Elderly patients with ESC or SIN have more comorbidities and relatively serious lesions. According to the location of the lesion, more detailed endoscopic observation and close follow-up should be carried out to improve the prognosis of such elderly patients.

Increases prognostic value of clinical-pathological nomogram in patients with esophageal squamous cell carcinoma

Background

This study was intended to construct a brand new prognostic nomogram after combine clinical and pathological characteristics to increases prognostic value in patients with esophageal squamous cell carcinoma.

Methods

A total of 1,634 patients were included. Subsequently, the tumor tissues of all patients were prepared into tissue microarrays. AIPATHWELL software was employed to explore tissue microarrays and calculate the tumor-stroma ratio. X-tile was adopted to find the optimal cut-off value. Univariate and multivariate Cox analyses were used to screen out remarkable characteristics for constructing the nomogram in the total populations. A novel prognostic nomogram with clinical and pathological characteristics was constructed on the basis of the training cohort (n=1,144). What's more performance was validated in the validation cohort (n=490). Clinical-pathological nomogram were assessed by concordance index, time-dependent receiver operating characteristic, calibration curve and decision curve analysis.

Results

The patients can divide into two groups with cut-off value of 69.78 for the tumor-stroma ratio. It is noteworthy that the survival difference was noticeable (P<0.001). A clinical-pathological nomogram was constructed by combining clinical and pathological characteristics to predict the overall survival. In comparison with TNM stage, the concordance index and time-dependent receiver operating characteristic of the clinical-pathological nomogram showed better predictive value (P<0.001). High quality of calibration plots in overall survival was noticed. As demonstrated by the decision curve analysis, the nomogram has better value than the TNM stage.

Conclusions

As evidently revealed by the research findings, tumor-stroma ratio is an independent prognostic factor in patients with esophageal squamous cell carcinoma. The clinical-pathological nomogram has an incremental value compared TNM stage in predicting overall survival.

Family history of cancer is a prognostic factor for better survival in operable esophageal squamous cell carcinoma: A propensity score matching analysis

Lay summary

Patients with a family history of cancer, especially digestive tract cancer and esophageal cancer, a family history of cancer in the first degree, and more than one relative affected by cancer were associated with favorable survival when compared to those without a family history of cancer.

A family history of cancer is a favorable independent prognostic factor in ESCC. Patients with a family history of cancer, especially digestive tract cancer and esophageal cancer, a family history of cancer in the first degree, and more than one relative affected by cancer were associated with favorable survival when compared to those without a family history of cancer.

Background

A family history of cancer (FH) is closely associated with the risk and survival of many cancers. However, the effect of FH on the prognosis of patients with esophageal squamous cell carcinoma (ESCC) remains unclear. We performed a large cohort study in the Chinese population to obtain insight into the prognostic value of FH in patients with operable ESCC.

Methods

A total of 1,322 consecutive patients with thoracic ESCC who had undergone esophagectomy between January 1997 and December 2013 were included. The FH group included patients with any degree of FH, while the non-FH group included patients without any degree of FH. In total, 215 patients with FH and 215 without FH were matched using the propensity score matching analysis method to adjust for differences in baseline variables between the two groups. The impact of FH on disease-free survival (DFS) and overall survival (OS) was estimated using the Kaplan-Meier method and Cox's proportional hazards models.

Results

Before matching, 280 (21.2%) patients were included in the FH group and 1,042 (78.8%) in the non-FH group. FH was associated with early pathological T stage (p = 0.001), lymph node-negative status (p = 0.022), and early pathological stage (p = 0.006). After matching, FH was an independent prognostic factor for DFS and OS in ESCC patients. Patients with FH had 35% lower risk of disease progression (hazard ratio [HR] = 0.65, 95% CI: 0.51-0.84, p = 0.001) and 34% lower risk of death (HR = 0.66, 95% CI: 0.51-0.86, p = 0.002) than those without FH. Patients with a family history of digestive tract cancer (FH-DC), a family history of esophageal cancer (FH-EC), FH in first-degree relatives (FH-FD), and more than one relative affected by cancer were associated with favorable DFS and OS as compared to those without FH.

Conclusion

FH is a favorable independent prognostic factor in ESCC. Patients with FH, especially those with FH-DC, FH-EC, FH-FD, and more than one relative affected by cancer, had improved survival.

Development and External Validation of an Improved Version of the Diagnostic Model for Opportunistic Screening of Malignant Esophageal Lesions

We aimed to develop an improved version of the diagnostic model predicting the risk of malignant esophageal lesions in opportunistic screening and validate it in external populations. The development set involved 10,595 outpatients receiving endoscopy from a hospital in Hua County, a high-risk region for esophageal squamous cell carcinoma in northern China. Validation set A enrolled 9453 outpatients receiving endoscopy in a non-high-risk region in southern China. Validation set B involved 17,511 residents in Hua County. The improved diagnostic model consisted of seven predictors including age, gender, family history of esophageal squamous cell carcinoma, smoking, body mass index, dysphagia, and retrosternal pain, with an area under the receiver operating characteristic curve (AUC) of 0.860 (95% confidence interval: 0.835-0.886) in the development set. Ideal discrimination ability was achieved in external validations (AUC _{validation set A}: 0.892, 95% confidence interval: 0.858-0.926; AUC _{validation set B}: 0.799, 95% confidence interval: 0.705-0.894). This improved model also markedly increased the detection rate of malignant esophageal lesions compared with universal screening, demonstrating great potential for use in opportunistic screening of malignant esophageal lesions in heterogeneous populations.

Effects of Helicobacter pylori infection in gastrointestinal tract malignant diseases: From the oral cavity to rectum

Helicobacter pylori (H. pylori) has infected approximately fifty percent of humans for a long period of time. However, improvements in the public health environment have led to a decreased chance of H. pylori infection. However, a high infection rate is noted in populations with a high incidence rate of gastric cancer (GC). The worldwide fraction of GC attributable to H. pylori is greater than 85%, and a high H. pylori prevalence is noted in gastric mucosa-associated lymphoid tissue lymphoma patients. These results indicate that the majority of GC cases can be prevented if H. pylori infection is eliminated. Because H. pylori exhibits oral-oral or fecal-oral transmission, the relationship between this microorganism and other digestive tract malignant diseases has also attracted attention. This review article provides an overview of H. pylori and the condition of the whole gastrointestinal tract environment to further understand the correlation between the pathogen and the host, thus allowing improved realization of disease presentation.

A Promising Esophageal Cancer Prognostic Signature of Ferroptosis-Related LncRNA to Predict Immune Scenery and Immunotherapy Response

Purpose

Ferroptosis and long non-coding RNA (lncRNA) expression signatures have been associated with the clinical progression and immune-contexture of different solid tumors. The study aimed to identify a prognostic signature of ferroptosis-related lncRNAs (falncRNAs) to forecast the immune scenery and immunotherapy response in esophageal cancer (EC).

Patients and Methods

Gene expression profiles of EC were extracted from The Cancer Genome Atlas (TCGA) database, and ferroptosis-related genes were downloaded from the FerrDb database, which identified differentially expressed falncRNAs (DEfalncRNAs) via differential analysis. DEfalncRNA pairs associated with prognosis were identified by constructing a matrix, univariate and least absolute shrinkage and selection operator (LASSO) analysis. The prognostic signature was constructed by multivariate analysis. We appraised the forecasting capability of prognostic signature in survival, clinicopathological features, immune landscape, efficacy of immunotherapy, and drug sensitivity. The potential molecular mechanism of signature was investigated by gene set enrichment analysis (GSEA).

Results

We obtained 18 DEfalncRNA pairs to define a novel prognostic signature that was determined on a discovery cohort of 158 tumor samples and 11 adjacent normal tissues from TCGA and internally validated, with the definition of high- vs low-risk groups based on 3 years overall survival. We demonstrated that the high- vs low-risk groups differed for clinical parameters and computationally predicted drug sensitivity and tumor immune contexture, with the high-risk group having worse survival, more aggressive disease (node involvement, metastasis), reduced drug sensitivity, higher tumor mutation load, and gene signatures of infiltration of pro-tumoral immune cell subsets. The GSEA results revealed that ferroptosis and immunoregulatory pathways were significantly enriched in the high-risk group.

Conclusion

The prognostic signature based on falncRNAs has the potential to forecast the survival, immune scenery, efficacy of immunotherapy, and drug sensitivity of EC, which is helpful for clinical prediction and individualized treatment.

Surgery for metachronous oligometastatic esophageal cancer: Is there enough evidence?

Esophageal cancer is the sixth most common cause of cancer-related mortality worldwide. Despite advances in diagnostic modalities and treatment options, five-year survival rates are below 20%. Esophagectomy with extended lymph node dissection is the mainstay of treatment. More than 50% of patients experience recurrence within 1-3 years postoperatively. Recurrent disease may present locoregionally at the site of anastomosis or as recurrence through lymphatic spread in lymph node basins, as hematogenic metastasis, or as a combination of these. The standard treatment of recurrence is currently predicated on systemic chemotherapy and/or radiotherapy. Recent evidence suggests that surgical treatment of metachronous oligometastatic disease may be prognostically advantageous over medical management alone. Given the considerably low response rates to chemoradiotherapy, many institutions have adopted surgical treatment strategies for oligo-recurrent disease on a case-by-case basis. The aim of this article is to review the current evidence on the role of surgical treatment for metachronous oligometastases from esophageal cancer.

Epidemiology of esophageal cancer: update in global trends, etiology and risk factors

Esophageal cancer is the eighth most common type of cancer worldwide and constitutes the sixth leading cause of cancer deaths. It is characterized by its high mortality rate, poor prognosis at time of diagnosis and variability based on geographic location. Present day, the prevalence of esophageal cancer is in transition. Although esophageal squamous cell carcinoma continues to be the most prevalent type worldwide, esophageal adenocarcinoma is quickly becoming the most prevalent type in developed countries. Risk factors for the development of esophageal squamous cell carcinoma include low socioeconomic status, consumption of tobacco, alcohol, hot beverages, and nitrosamines. Additionally, micronutrient deficiencies have also been linked to the development of esophageal squamous cell cancer. These include vitamin C, vitamin E, and folate. With respect to esophageal adenocarcinoma, risk factors include Barrett's esophagus, gastroesophageal reflux disease, obesity, and tobacco consumption. Screening for esophageal cancer will likely play an essential role in prevention, and consequently, mortality in the future. Present day, there are no established guidelines for esophageal squamous cell cancer screening. Guidelines for esophageal adenocarcinoma are more well established but lack concrete evidence in the form of randomized controlled trials. This review will discuss the epidemiology, risk factors, and current prevention strategies for esophageal cancer in depth. It is our aim to raise awareness on the aforementioned topics to increase public health efforts in eradicating this disease.
