The goal of this observational study is to learn about in describe participant population. The main questions it aims to answer are: - What are the risk factors of postoperative pulmonary infection in patients with esophageal cancer？ - Whether we could establish a clinical prediction model to provide basis for early clinical intervention or not? Participants will describe the main tasks participants will be asked to do, treatments they'll be given and use bullets if it is more than 2 items. If there is a comparison group: Researchers will compare insert groups to see if insert effects.
This is a population-based case-control study in all 5 Nordic countries from 1994 onwards. All cases with an esophageal or gastric tumor will be compared with 10 times as many population controls, frequency-matched by age, sex, and calendar year, country. This design offers excellent statistical power, length and completeness of follow-up, quality of data on exposures, outcomes and confounders, and control for confounding. The project will include a specific study entitled "Long-term medication with proton pump inhibitors and risk of gastric cancer", which is summarized here: Research question: Medication with proton pump inhibitors (PPI) (e.g., omeprazole and esomeprazole) is one of the most common long-term therapies globally, prompted by its high anti-acidic efficacy and good short-term safety profile. Gastric cancer is the 3rd leading cause of cancer-related mortality globally, responsible for 770,000 deaths each year. There are clear biological mechanisms linking long-term PPI-use with an increased risk of gastric cancer. However, existing research has not been able to provide a definite answer to whether long-term PPI-use is associated with an increased risk of gastric cancer. The reasons are that the literature is hampered by too short follow-up time to assess cancer development, and also insufficient statistical power, lack of population-based design and confounding. With the availability of nationwide complete medication registries in the Nordic countries, the firsts two starting already in 1994 (Denmark and Finland), we can now, by adding registry data from all Nordic countries together, conduct the first study providing a robust and valid answer to this research question. Overarching aim This project aims to clarify if (and if so to what extent) long-term PPI-therapy influences the risk of developing gastric adenocarcinoma. For validation reasons, we will also examine how long-term use of histamine-2-receptor blockers (H2RB) influences the risk of developing gastric adenocarcinoma. These analyses will validate that the findings are specific for PPIs. H2RB are used for the same indications as PPIs, but with a different biological mechanism. Hypothesis We plan to test the hypothesis that long-term use of PPI (but not H2RB) increases the risk of gastric adenocarcinoma. Prerequisites This will be the first project with all prerequisites to provide conclusive answers to the hypotheses above, i.e.: - Long follow-up (up to 28 years) - Complete follow-up (by virtue of the nationwide complete Nordic registries) - Population-based design (which rules out biased selection of cases or controls) - Superior statistical power (all five Nordic countries participate with nationwide data) - High-quality data on exposures, outcomes and confounders (thanks to well-maintained and complete nationwide Nordic health data registries) - Control for confounding factors (available for all participants, both cases and controls)
The goal of this observational study is to test the clinical efficacy of "KCNA3 and OTOP2 gene methylation combined detection kit (fluorescence PCR method)"in esophageal cancer and high-grade esophageal neoplasia auxiliary diagnosis.The main questions it aims to answer are: 1. How consistent are the test results of the kit with the clinical reference diagnostic criteria? 2. Sanger sequencing can visually show whether each sample contains methylation sites, so in this clinical trial, the kit results were compared with Sanger sequencing results to analyze the reagent's accuracy in detecting KCNA3 and OTOP2 gene methylation. Each participant is required to provide no less than 10 ml of blood to complete the kit test.
It is reported that compared to chemotherapy alone, immunochemotherapy has significantly improved the overall survival of patients with advanced metastatic ESCC. However, there are still more than 30% of patients who cannot benefit from this treatment modality. In addition to these factors, the time-of-day infusion and administration sequence of immunochemotherapy have been reported to be associated with tumor responses and overall survival. In this study, The investigators aimed to explore the roles of infusion time and administration sequence of immunochemotherapy in predicting tumor responses and overall survival in patients with advanced ESCC.
This single-center, retrospective cohort study aimed to evaluate the short-term outcomes of enhanced recovery after surgery (ERAS) protocol in perioperative robotic-assisted McKeown esophagectomy (RAME) among esophageal cancer patients.
Most ESCC received NAC in China without supportive evidence from local RCTs. The negative conclusion about NAC originated from Western countries in the 1990s. Whether two-field extensive mediastinal lymphadenectomy and paclitaxel/platinum-based chemotherapy results in better survival should be determined. As the highest ESCC incidence area worldwid, we tried to analyze this top with big data by using a single-center case-control retrospective PMS study. Paclitaxel- and platinum-based NAC combined with two-field of the extensive mediastinal lymphadenectomy might provide better survival benefits than primary esophagectomy for stage II/III SCC.
The study type was designed as a prospective multicenter randomized controlled study. The patients will be divided into intervention group and control group, 281 patients were needed for each group and 562 patients would be needed totally to show this difference. Due to a possible loss of 14%, the final sample size was calculated to be 652 patients. The intervention group will not implement mechanical bowel preparation(MBP) before surgery; the control group will receive routine preoperative MBP for oral administration of compound polyethylene glycol electrolyte powder and fasting water. Perioperative complications, intestinal recovery speed and quality of life will be investigated between the two groups.
Endoscopic Resection (ER) is a crucial therapeutic and diagnostic method for superficial esophageal cancer. However, lymph node metastasis rate in pT1b patients is relatively high. Although, adjuavnt chemoradiotherapy is recommended, limied studies prove the superiority of additional adjuvant radiotherapy over ESD alone. This study aimed to further verify the efficacy of adjuvant radiotherapy in early-stage esophageal cancer after ESD.
