To evaluate the clinical usefulness of taxanes as antitumor agents, we compared the antitumor spectrum of taxanes with those of conventional antitumor agents against 88 fresh gastric cancer specimens by MTT assay. At cut-off concentrations of 100 micrograms/ml for taxotere (Docetaxel, DOC) and 300 micrograms/ml for taxol (Paclitaxel, PAC), both agents showed a higher efficacy rate than mitomycin C (MMC), cisplatin (CDDP) and 5-fluorouracil (5-FU) against the gastric cancer specimens. The patterns of antitumor activity of DOC and PAC were independent from those of the conventional agents, while the patterns of antitumor activity of the taxanes significantly correlated with each other. Conventional agent antitumor activity patterns tended to correlate with the patterns of other conventional agents. In conclusion, taxanes may be useful for clinical application against gastric cancer due to their different antitumor spectrum as compared to conventional agents.

This case was a 69-year-old male who had advanced gastric cancer with unresectable multiple liver metastases (Stage IV). He received a combination therapy consisting of a continuous venous infusion (cisplatin: CDDP 10 mg/body, 5-FU 500 mg/body, day 1-28). As a result, metastatic tumors in the liver completely disappeared and a total gastrectomy was sequentially performed. Four years after the surgery, neck lymph node (LN) metastases and the right adrenal metastasis appeared, and chemotherapy (TS-1, and sequentially TS-1+CDDP) was performed. But, the chemotherapy to eradicate the metastases was hardly enough to be effective. Next, docetaxel (DOC 60 mg/m2 q3w) was started. After 9 courses, they were effective and marked regressions (70%). A total of 15 courses of docetaxel administration were possible until tumor progression recurred. This regimen was not severe in toxicity for the duration except for grade 3 poor appetite. Docetaxel will be a key drug for the gastric cancer. In case of responding well to the chemotherapy, we can hope for an extended long-term survival with a continuation of this regimen.

The patient was a 63-year-old woman who presented with upper abdominal discomfort. Type 3 gastric cancer in the midgastric region was diagnosed, and the patient underwent surgery. Because peritoneal metastasis and periaortic lymph node metastasis were confirmed, paraaortic lymph node metastasis, total gastrectomy and D 1 lymph node dissection were performed. Surgical and pathological findings were pType 3, pT 3(SE), sN 3, pP 1, sH 0, CY 1, Stage IV, and Cur C. After surgery, she was treated with five regimens of MTX/5-FU, TS-1 or DOC, but because progressive disease was confirmed, weekly paclitaxel and 5'-DFUR combination therapy was initiated as salvage therapy. Five months after the start of combination therapy, complete response was achieved, and combination therapy was continued for 19 more months. Since no recurrence was observed, therapy was terminated. No severe adverse reactions were observed. The patient has been recurrence-free for 25 months and remains alive as of 68 months after surgery. The present therapy may thus be effective in the treatment of previously treated Cur C advanced gastric cancer.

The patient was a 54-year-old male with peritoneal dissemination and carcinomatous ascites of advanced gastric cancer. Although 4 months of temporary partial responses were obtained by a combination chemotherapy with TS-1 and DOC, retention of ascites appeared. Second-line combination chemotherapy with 5-FU and PTX was not effective, and we attempted to use intraperitoneal chemotherapy of low-dose CDDP. After 100 mg of CDDP had been administered, ascites almost disappeared. Then,intraperitoneal injection of low-dose CDDP and intravenous injection of 5-FU were given. Tumor marker decreased remarkably, and CT revealed reduction of peritoneal dissemination. These regimens seem to be effective in ambulant patients with advanced gastric cancer with peritoneal dissemination and carcinomatous ascites.

We report a case of multiple bone metastases from gastric cancer treated with combination chemotherapy of S-1 and CDDP. A 54-year-old man underwent distal gastrectomy for gastric cancer (Stage II) in March 2003. Multiple bone metastases complicated with DIC were diagnosed in September 2005. The patient was treated with combination chemotherapy of S-1 and CDDP. S-1 (80 mg/m2/day) was administered for 21 days followed by 14 days rest as one course. CDDP (60 mg/m2) administration was begun 8 days after the start of S-1. After one course of the treatment, DIC was resolved. The abnormal uptake at the bone metastases was found to have decreased by bone scintigraphy. Bone metastases recurred in April 2006. Although combination chemotherapy of S-1 and DOC was administered, the patient died of DIC in August 2006. Combination chemotherapy of S-1 and CDDP is considered effective treatment for prolonging survival in cases of gastric cancer with bone metastases.

We report a case of long-term survival of 5 years after operation and chemotherapy for type 4 gastric cancer with peritoneal dissemination. A 41-year-old woman underwent total gastrectomy for type 4 gastric cancer with peritoneal dissemination and pancreas invasion. After operation, chemotherapy with S-1 plus PSK therapy, S-1 plus CDDP, and S-1 plus DOC was performed. The regimen of S-1 plus CDDP included S-1 on day 1-5, 8-12, 15-19, 22-26 and 2 weeks rest and PSK daily. After S-1 plus PSK therapy(34th course), peritoneal recurrence caused ileus, so a right hemicolonectomy was performed. Now the patient is undergoing weekly paclitaxel. The S-1 plus PSK therapy is able to prolong time to progression and has fewer adverse effects.

We report a case of a 48-year-old male with advanced gastric cancer. A total gastrectomy was performed for cancer of remnant stomach. S-1 was administered for cytological cancer cells detected by abdominal cavity lavage as the first-line chemotherapy. After 2 cycles of S-1, cervical lymph nodes were enlarged, and the patient underwent paclitaxel monotherapy as the second-line chemotherapy. After 8 cycles, Virchow lymph nodes were enlarged. The regression of Virchow lymph nodes were observed with a S-1 /CPT-11 combination therapy as the third-line chemotherapy and DOC/CPT-11 as the fourth-line chemotherapy. We then used a combination chemotherapy of CPT-11 60 mg/m2 and CDDP 30 mg/m2 at day 1 and 15, every 4 weeks as the fifth-line chemotherapy. A partial response was achieved after 2 cycles, and has been continued for 7 months. The hematological toxicities and the non-hematological toxicities of grade 2 or higher were not observed. This regimen may be effective for patients with advanced gastric cancer resistant to prior chemotherapy with several agents.

Case 1: The patient underwent gastrojejunostomy [T4 (pancreas), N2, P0, CY0] in April 2004, and then 23 courses of chemotherapy with S-1 + DOC (40 mg/m2/day 1:3 w). Then, the regimen was switched to CPT-11 because of a decreased efficacy of the treatment, and CPT-11 was continued for 10 courses. (The patient was alive for 36 months). Case 2: The patient was treated with S-1 [T4 (pancreas), N3, P0, CY0] after surgical bypass in November 2004. After two courses of chemotherapy with S-1, 9 courses of the second-line chemotherapy with PTX (120 mg/m2/day 1:3 w) were provided. As the disease progressed, 15 courses of CPT-11 (125 mg/m2/day 1: 2 w) were administered (The patient was alive for 29 months). Case 3: The patient was diagnosed as CY1 by staging laparoscopy in August 2005. The second-look laparoscopy revealed CY0 after 5 courses of S-1 + PTX (120 mg/m2/day1: 3 w). Although the second-look laparoscopy revealed CYO, gastrojejunostomy was performed because of P1 and T4 (pancreas). Chemotherapy with S-1 + PTX was continued for 18 courses, followed by OPT-11 (The patient was alive for 20 months). This report describes three cases of gastric cancer treated with S-1 based chemotherapy after surgical bypass, which resulted in the long-term survival and an improvement of the patients' quality of life.

We performed combination chemotherapy in the outpatient clinic on a 47-year-old man with nonresected gastric cancer accompanied by peritoneal dissemination. At first we administered S-1/DOC combination chemotherapy. Afterwards a rise of tumor marker (CEA) occurred accompanying taste disorder and edema of the lower limbs, so we changed to combination chemotherapy for PTX/CDDP. Since the only side effect was numbness, the patient was treated on an outpatient basis while working. The case achieved good QOL by these combination chemotherapy methods for 1 year 10 months post exploratory laparotomy.

Preoperative intra-peritoneal chemotherapy (IPC) for scirrhous gastric cancer (SGC) has been performed and followed after laparoscopic diagnosis of peritoneal metastasis (P) or washing cytology (CY) in our hospital. Between 2002 and 2005, 15 SGC patients were treated with 3 times of IPC using CDDP (50 mg/body) before operation (CDDP group). Between 2006 and 2008, 9 SGC patients were treated with IPC using docetaxel: DOC (40 mg/m2) and treated with systemic chemotherapy using S-1 (80 mg/m2) before operation (DOC group). Cases with P (+) or CY (+) were detected in 80% in CDDP group and in 89% in DOC group. Gastrectomy was performed in 67% of CDDP group and in 56% of DOC group. All of the 15 patients died in CDDP group but 4 of 9 were still alive in DOC group. The median survival time of DOC group (22 months) was longer than that of CDDP group (10 months, p=0.123). Thus, preoperative IPC using DOC combined with systemic chemotherapy using S-1 should be effective treatment for SGC.
