The purpose of this study is to assess efficacy and safety of docetaxel alone, docetaxel plus cisplatin, and docetaxel plus S-1 in patients with metastatic gastric cancer after failing 1st line chemotherapy with cisplatin plus S-1 or capecitabine
To date, the most commonly used first-line chemotherapies have been based on fluorouracil and/or cisplatin in patients with metastatic gastric cancer. Unfortunately, considerable proportions of patients with metastatic gastric cancer do not respond to first-line chemotherapy and most of the patients who do respond eventually experience disease progression. In the second-line treatment, however, standard therapies are less clearly defined.
Meanwhile, regarding re-challenge of previous failed drugs as a combination with an other newly introduced chemotherapeutic agent, there are few data. Increased expression and activity of thymidylate synthase, which is inhibited by fluoropyrimidine, is regarded to be the main reason for the development of clinical resistance to fluoropyrimidine. Since the cotreatment of docetaxel and 5-fluorouracil decreases the activity and expression of thymidylate synthase and dihydropyrimidine dehydrogenase (5-fluorouracil degradation enzyme), and increases the expression of orotate phosphoribosyl transferase, the addition of docetaxel into S-1 may recover the sensitivity to S-1 in patients previously resistant to S-1.
Several reports found that MDR-1 and MRP-1 are related to cisplatin-resistance; cisplatin induces the overexpression of MRP-1, which reduces intracellular cisplatin accumulation. Since docetaxel suppresses the cisplatin-induced MRP-1 upregulation, the addition of docetaxel into cisplatin may recover the sensitivity to cisplatin in patients previously resistant to cisplatin.
Based on these synergism mechanisms, we speculate that the cotreatment of docetaxel and cisplatin or S-1 has better anti-tumor activity than docetaxel alone in patients resistant to cisplatin or S-1.

That portion of the stomach remaining after gastric surgery, usually gastrectomy or gastroenterostomy for cancer of the stomach or peptic ulcer. It is a common site of cancer referred to as stump cancer or carcinoma of the gastric stump.
A proto-oncogene protein and member of the Wnt family of proteins. It is frequently up-regulated in human GASTRIC CANCER and is a tumor marker (TUMOR MARKERS, BIOLOGICAL) of gastric and COLORECTAL CANCER.
A deoxycytidine derivative and fluorouracil PRODRUG that is used as an ANTINEOPLASTIC ANTIMETABOLITE in the treatment of COLON CANCER; BREAST CANCER and GASTRIC CANCER.
An inorganic and water-soluble platinum complex. After undergoing hydrolysis, it reacts with DNA to produce both intra and interstrand crosslinks. These crosslinks appear to impair replication and transcription of DNA. The cytotoxicity of cisplatin correlates with cellular arrest in the G2 phase of the cell cycle.
