The goal of this clinical trial is to learn if precision palliative care improves survival of patients with advanced esophageal cancer in adults.

Researchers will compare precision palliative care and standard palliative care to see if precision palliative care works more effectively to treat advanced esophageal s cancer.

Participants will receive precision palliative care or standard palliative care. All participants will answer survey questions about their quality of life, MDASI, PHQ-9, GAD-7 for 1 years.

3. Disease progression occurs within 3months after anti-PD-1/PD-L1 immunotherapy.

4. Allergic to macromolecular protein preparations, or to any of the ingredients in anti-PD-1/PD-L1 inhibitors for injection.

5. Uncontrolled heart diseases or clinical symptoms, such as: (1) New York Heart Association(NYHA) class II or higher heart failure; (2) unstable angina; (3) myocardial infarction within 1 year; (4)clinically significant arrhythmia requiring clinical intervention.

6. Congenital or acquired immunodeficiency (such as HIV infection); active hepatitis B (HBV-DNA≥104 copy number/ml) or hepatitis C (positive hepatitis C antibody, and HCV-RNA is higher than the detection limit of the analytical method); active tuberculosis.

7. Active infection or unexplained fever >38.5 °C within 2 weeks before randomization (fever due to tumor excepted, according to investigator).

   Patients with fertility reluctant to take contraceptive measures during the trial, or female patients pregnant or breastfeeding.

8. According to the investigator, other factors that may cause termination of the study. ie, other serious diseases (including mental illness) require combined treatment, family or social factors, which may affect the safety or the collection of trial data.

in this study, all subjects are diagnosed with stages IV esophageal cancer or recurrent esophageal cancer. All subjects plan to treated with anti-PD-1/PD-L1 immunotherapy. Subjects are inpatients or outpatients.
