Is this trial a fit for you?

Likely a good fit

Ideal candidates are individuals with histologically confirmed locally advanced esophagogastric junction adenocarcinoma who have not undergone previous anti-tumor treatment.

Probably not a fit

Patients with prior anti-tumor treatments or those with severe organ dysfunction may not benefit from this study.

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This study evaluates the safety and effectiveness of combining immunotherapy with chemotherapy for patients with locally advanced esophagogastric junction adenocarcinoma. Participants will receive Sintilimab, a PD-1 inhibitor, alongside Tegafur and Oxaliplatin. The goal is to determine how well this treatment works before surgery in patients who have not received prior anti-tumor therapies. The study focuses on patients with specific tumor characteristics and organ function requirements.

Why it matters

Potential benefit: If successful, this treatment could improve outcomes for patients with advanced esophagogastric junction adenocarcinoma.

How similar studies have gone: Other studies have shown promising results with similar immunochemotherapy approaches in treating various cancers, suggesting potential for success in this context.

* No previous anti-tumor treatment
* ECOG PS: 0-1
* The functions of important organs meet the following requirements (excluding the use of any blood components and cell growth factors during the screening period):Absolute neutrophil count ≥ 1.5 × 109/L; Platelet ≥ 90 × 109/L; Hemoglobin ≥ 9g / dl; Serum albumin ≥ 3G / dl; Thyroid stimulating hormone (TSH) ≤ ULN (if abnormal, the levels of T3 and T4 should be investigated at the same time. If the levels of T3 and T4 are normal, they can be included in the group); Bilirubin ≤ ULN; ALT and AST ≤ 1.5 times ULN; AKP ≤ 2.5 times ULN; Serum creatinine ≤ 1.5 times ULN or creatinine clearance ≥ 60ml / min.

For men, they must agree to use appropriate methods of contraception or surgical sterilization during the trial and 8 weeks after the last administration of the trial drug.
* The patients voluntarily joined the study and signed the informed consent form. They had good compliance and cooperated with the follow-up.

Exclusion Criteria:

* Known Her-2 positive
* Any active autoimmune disease or history of autoimmunity (as follows, but not limited to: autoimmune hepatitis, interstitial pneumonia, uveitis, enteritis, hepatitis, hypophysitis, vasculitis, nephritis, hyperthyroidism and hypothyroidism; Subjects with vitiligo or asthma in childhood have been completely relieved and do not need any intervention after adulthood can be included; Asthma in which subjects need bronchodilators for medical intervention cannot be included).
* Severe allergic reaction to monoclonal antibody.
* The number of neutrophils in peripheral blood was less than 1500 / mm3.
* There are cardiac clinical symptoms or diseases that are not well controlled.
* Previously received radiotherapy, chemotherapy, hormone therapy, surgery or molecular targeted therapy.
* The subjects were innate or acquired immunodeficiency (such as HIV), or active hepatitis (hepatitis B reference: HBsAg) positive, HBVDNA \> 2000IU/ml or copy number \> 104/ml; Hepatitis C reference: HCV antibody positive.
* According to the judgment of the researcher, the subject has other factors that may lead to the forced midway termination of this study, such as other serious diseases (including mental diseases) requiring combined treatment, serious laboratory abnormalities, accompanied by family or social factors, which will affect the safety of the subject, or the collection of data and samples.
* The researchers judged the patients with high risk of esophageal perforation or no potential possibility of surgery through endoscopic ultrasonography or imaging.
