Those who cannot tolerate cisplatin chemotherapy, but can use carboplatin, etc., and radiographically confirmed disease progression or recurrence occurs during or after treatment; Not suitable for platinum-containing chemotherapy; Patients with advanced esophageal squamous cell carcinoma failure with previous immune checkpoint suppression agents such as PD-1/PD-L1; Exclusion Criteria: Previously diagnosed with fibrolamellar hepatocellular carcinoma, sarcomatoid hepatocellular carcinoma, cholangiocarcinoma, etc. by histology or cytology; Pathological histology classification is squamous cell carcinoma (adenosquamous carcinoma including squamous cell carcinoma), carcinoid tumor, undifferentiated carcinoma or other gastric cancer/gastroesophageal junction adenocarcinoma that cannot be classified; Subjects with gastric adenocarcinoma/gastroesophageal junction adenocarcinoma known to be human epidermal growth factor receptor 2 (HER2)-positive (patients with unknown HER2 status must be confirmed at the local hospital) shall be excluded, but HER2-positive patients with disease progression after trastuzumab treatment can be enrolled; Previous treatment with anti-angiogenic drugs such as cabozantinib, apatinib, lenvatinib, sorafenib, sunitinib, bevacizumab (except subjects with advanced hepatocellular carcinoma) History of hepatic brain; According to imaging examination, the main trunk of the portal vein has cancer thrombus invasion, inferior vena cava or heart involvement; Hepatitis B combined with hepatitis C or hepatitis D infection; Patients who are preparing for or have received organ transplantation in the past; Other malignant tumors within 5 years (except for cured basal cell carcinoma of the skin, prostate carcinoma in situ and carcinoma in situ of the cervix, etc.); Those with a variety of factors that affect oral drugs (such as inability to swallow, chronic diarrhea and intestinal obstruction, etc.); Patients with moderate to severe ascites with clinical symptoms requiring repeated drainage; Patients with uncontrolled pleural effusion and pericardial effusion; Patients with any bleeding or bleeding events ≥ CTCAE grade 3 within 4 weeks before the first dose; Patients with arteriovenous thrombotic events, such as cerebrovascular accident (including transient ischaemic attack), deep vein thrombosis, and pulmonary embolism, within 6 months prior to the first dose, are allowed to be treated with low molecular weight heparin, and antiplatelet agents are contraindicated throughout the study period; Those who have previously received radiotherapy, chemotherapy, surgery, etc., within less than 4 weeks before the first dose of study drug, less than 5 half-lives of oral targeted drugs or less than 14 days of oral fluorouracils; There are unhealed wounds, fractures, active ulcers of the stomach and duodenum, persistent positive fecal occult blood, ulcerative colitis, etc., or other conditions that may cause gastrointestinal bleeding and perforation as determined by the investigators; Liver cancer subjects have a history of gastrointestinal bleeding within 6 months before the first dose; Patients with portal hypertension have a high risk of bleeding considered by the investigators, or have a red sign confirmed by gastroscopy or gastroscopy. Other factors that the investigator determines that the subjects are not suitable to participate in this study; Subjects with Epidermal Growth Factor Receptor (EGFR) mutation and known anaplastic lymphoma kinase (ALK) translocation (for Advanced non-small cell lung cancer); Central squamous cell carcinoma with large hemoptysis risk (for Advanced non-small cell lung cancer)
