Brief summary: Investigators conduct the clinical trial to further explore the efficacy and safety of Fruquintinib combined with S-1 in treating recurrent or metastatic esophageal squamous cell carcinoma after the failure of conventional treatments.

Detailed description: Esophageal cancer is one of the most common malignant tumor and esophageal squamous cell carcinoma is the main pathological type of esophageal carcinoma in China. Among patients with advanced or metastatic esophageal squamous cell carcinoma, the addition of immunotherapy to chemotherapy, compared with placebo and chemotherapy, significantly improved overall survival and progression-free survival.Treatment of recurrent or metastatic esophageal squamous cell carcinoma is usually poor. New treatments were needed. Fruquintinib is an orally antiangiogenic agents, which target VEGFR1/2/3. A combination of Fruquintinib and s-1 for advanced or metastatic esophageal squamous cell carcinoma could be a novel therapy. Therefore, investigators initialize this phase II study to explore the safety of fruquintinib and S-1 combination treatment in ESCC patients with after failure in 1st-line immunotherapy.

Eligibility criteria: Inclusion Criteria:

* Male or female patients, age:≥18 years old
* Imageology diagnosed with refractory or metastatic esophageal squamous cell carcinoma
* Disease progression after the last dose of the first-line therapy (with immunotherapy, without fluoropyrimidine)

* Good performance status Eastern Cooperative Oncology Group (ECOG) Performance Status (PS) 0 to 2
* Life expectancy of more than 12 weeks
* The test value for bone marrow, liver and renal function evaluation within 7 days prior to first dosing should meet requirements
* Negative of blood pregnancy test within 7 days prior to first dosing for fertile female patients. Fertile female and male patients agree to use effective contraceptive methods during the study and within 6 months post to the last dose, such as double barrier contraception, condoms, oral or injection contraceptives, intrauterine devices, abstinence, etc. All female patients will be considered fertile unless the female patient has natural menopause or has undergone artificial menopause or sterilization (hysterectomy, bilateral appendage resection);
