Descripción detallada
There are two primary objectives in different steps. In the first step, the primary objective of this study is to investigate the objective response rate in patients receiving sequential capecitabine plus oxaliplatin followed by docetaxel plus capecitabine in patients with unresectable gastric adenocarcinoma.
In the second step, the primary objective of this study is to screen the predictive biomarkers of three different chemotherapeutic drugs and also investigate the objective response rate in patients receiving sequential capecitabine plus oxaliplatin followed by docetaxel plus capecitabine in patients with unresectable gastric adenocarcinoma.

Experimental: chemotherapy
Chemotherapy: Drug: Capecitabine, Oxaliplatin, Docetaxel Dosing Regimena: total of 6 cycles of modified XELOX regimen repeats every 2 weeks, and followed by 4 cycles of TX repeats every 3 weeks. After 10 cycles of treatment, patients may continue to treat with either of the regimen, preferably the one having the best efficacy. |

Objective response rate
Periodo de tiempo: Every 6 weeks

Tumor responses in measurable lesions are to be evaluated by the tumor response guidelines validated by the Response Evaluation Criteria in Solid Tumors (RECIST) Group .
The new version 1.1 was published in 2009.

Be calculated as the duration between the first date of randomization and the date of disease recurrence or progression according to RECIST (failed), taking the status of tumor at the treatment has been completed as the reference, or death (failed), or the date of withdrawal (last contact date, censored), or the scheduled data analysis date (censored).
