leucovorin + fluorouracil + oxaliplatin + camrelizumab + apatinib

This is a multi-agent combination therapy consisting of five drugs with distinct mechanisms of action, primarily used or investigated for advanced solid tumors such as colorectal cancer and other gastrointestinal malignancies. - **Leucovorin** is a reduced folate that enhances the cytotoxicity of fluorouracil by stabilizing its binding to thymidylate synthase[2][3]. - **Fluorouracil** is an antimetabolite that inhibits thymidylate synthase, disrupting DNA synthesis[2][3]. - **Oxaliplatin** is a platinum-based chemotherapeutic agent causing DNA crosslinking and apoptosis[4][5]. These three agents are commonly combined as the FOLFOX regimen for colorectal cancer. Adding: - **Camrelizumab**, a monoclonal antibody targeting PD‑1 on T cells, acts as an immune checkpoint inhibitor to enhance anti-tumor immunity[6][7][10]. - **Apatinib**, a small molecule tyrosine kinase inhibitor selectively targeting VEGFR2, inhibits tumor angiogenesis and has shown synergistic effects with immunotherapy agents like camrelizumab[6][7][10]. This five-drug combination aims to maximize anti-tumor efficacy through cytotoxic chemotherapy, immune checkpoint blockade, and antiangiogenic therapy. It has been studied in various advanced cancers including esophageal squamous cell carcinoma, nasopharyngeal carcinoma, adrenocortical carcinoma, among others.
