A distinctive subtype of gastric adenocarcinoma with extensive bone marrow metastasis and DIC has been described. Few patients have been treated properly due to the lack of standard care. We designed this phase II study to evaluate a dose-dense regimen for this kind of highly aggressive gastric cancer (HAGC).

5-fluorouracil 200mg/square metre/day continuously venous infusion on days 1-21; Docetaxel 25mg/square metre, on days 1, 8 and 15; This regimen repeats every 4 weeks.

• ECOG PS 0-3;
• Pathologically confirmed adenocarcinoma in stomach or esophagogastric junction;
• Bone marrow metastasis confirmed by aspiration, biopsy or PET/CT scan;
• overt DIC according to the International Society on Thrombosis and Haemostasis (ISTH) criteria;
• Treatment-naive after the diagnosis of metastasis;
• Platelet ≤ 50 * 10E9/L;
• ALT≤5×ULN, AST≤5×ULN, Bilirubin≤5×ULN, Creatinine≤3×ULN;
• Written informed consent.

Exclusion Criteria:

• Concurrent aggressive malignancy;
• Docetaxel containing perioperative treatment within 6 months;
• Allergic to the study drugs;
• Serious medical conditions, including severe heart disease, severe cerebrovascular disease, uncontrolled diabetes, uncontrolled hypertension, uncontrolled infection,etc.
