Summary

Esophageal squamous cell carcinoma (ESCC) is one of the malignant tumors with a high incidence worldwide, especially remaining persistently high in Asian regions. Despite advancements in early diagnosis and comprehensive treatment, most patients are already in the locally advanced or metastatic stage at the time of initial diagnosis, resulting in an extremely poor prognosis. The objective response rate (ORR) of first-line chemotherapy regimens (such as platinum-containing dual-drug combinations with fluorouracil) is less than 50%, and the median progression-free survival (PFS) is only 3-6 months. Moreover, the options for second-line treatment are more limited. Currently, there is no unified standard for second-line treatment, and there is an urgent need to explore new and effective regimens.

Anlotinib is a multi-target tyrosine kinase inhibitor that can target and inhibit vascular endothelial growth factor receptor (VEGFR), fibroblast growth factor receptor (FGFR), and platelet-derived growth factor receptor (PDGFR). It exerts anti-tumor effects through anti-angiogenesis and regulation of the tumor microenvironment. Single-agent anlotinib has shown certain efficacy in advanced esophageal cancer. A phase II study indicated that the ORR of single-agent anlotinib in second-line treatment was 9.7%, with a median PFS of 3.0 months.

Suyuan (trifluridine/tipiracil) is a new oral fluoropyrimidine drug composed of trifluridine (a cytotoxic component) and tipiracil (a synergist that inhibits the metabolic enzyme TP), which can overcome the resistance to traditional fluorouracil. Single-agent Suyuan has achieved significant survival benefits in metastatic colorectal cancer, and its synergistic effect in combination with anti-angiogenic drugs in solid tumors has also been preliminarily confirmed.

The biological basis of combination therapy: Anti-angiogenic drugs can improve the hypoxic state of the tumor microenvironment, enhance the delivery efficiency of chemotherapy drugs, and simultaneously inhibit the infiltration of immunosuppressive cells. Their combination with chemotherapy or immunotherapy has potential synergistic effects. Preclinical studies have shown that anlotinib combined with fluoropyrimidine drugs can significantly inhibit the growth of esophageal cancer models by dual inhibition of tumor proliferation and angiogenesis pathways.

Based on the above background, this study intends to explore the efficacy and safety of Suyuan combined with anlotinib in the second-line treatment of recurrent and metastatic ESCC, aiming to provide new treatment options for patients.
