Apatinib With Oxaliplatin and S-1 Treatment for Advanced Hepatoid Adenocarcinoma Of The Stomach
Study Details
Study Description
Brief Summary
Gastric cancer is a highly heterogeneous tumor. The most commonly used clinical classifications of gastric cancer are Lauren classification (intestinal, diffuse, mixed) and World Health Organization(WHO) classification (papillary adenocarcinoma, tubular adenocarcinoma, mucinous glands cancer and low-adhesion cancer). Hepatoid adenocarcinoma of the stomach (HAS) is a special and rare type of gastric cancer.
Compared with ordinary gastric cancer, HAS has unique clinicopathological characteristics, prone to liver metastasis and lymph node metastasis, has a highly aggressive and malignant biological behavior, a worse prognosis than alpha fetoprotein(AFP) normal gastric cancer, and is easily confused with hepatocellular carcinoma(HCC). There is the possibility of misdiagnosis and mistreatment, so it has gradually attracted people's attention. Most of the domestic and foreign literature on HAS in the past 30 years are retrospective cases or small sample reports, and there are few prospective studies. There is no standard treatment plan for HAS. The main treatment is based on gastric adenocarcinoma. The clinical treatment principle is a comprehensive treatment plan with surgical resection as the mainstay, supplemented by systemic chemotherapy and local interventional therapy. This type of gastric cancer has a relatively high degree of malignancy, rapid progress of the disease, and easy recurrence after surgery. There is no standard treatment plan in China and other foreign countries.
The aim of this study was to evaluate the efficacy and safety of apatinib with oxaliplatin and S-1 treatment advanced hepatoid adenocarcinoma of the stomach.

Outcome Measures
Primary Outcome Measures
- Objective Response Rate（ORR） [Estimate up to 2 years.]
The percentage of patients having a complete response(CR) or a partial response(PR) to protocol treatment. Objective response will be measured by RECIST 1.1.
Secondary Outcome Measures
- Overall Survival (OS) [Estimate up to 5 years.]
The length of time from enrollment until the time of death.
- Progression-free Survival (PFS) [Estimate up to 2 years.]
The time from enrollment to the first documented disease progression per RECIST 1.1 based on investigator assessment, or death due to any cause, whichever occurs first.
- Disease Control Rate (DCR) [Estimate up to 2 years.]
The percentage of the participants in the analysis population who had a confirmed CR or PR or stable disease(SD) according to RECIST 1.1 based on investigator assessment.
- Adverse events [Estimate up to 2 years.]
The incidence of adverse events and the incidence of severe adverse events
