We report three successful cases with continuous systemic chemotherapy for advanced gastric cancer. Case 1: A 67-year-old male with gastric cancer. Abdominal CT showed the invasion in the pancreas and as a result, continuous systemic infusion of low-dose cisplatin (CDDP 20 mg/day) and 5-fluorouracil (5-FU 1,000 mg/day) was performed. This infusion chemotherapy, CDDP and 5-FU, was continued for 5 days and discontinued for 25 days. Three months after the chemotherapy, the main tumor was remarkably reduced (downstaging was obtained), and consequently, total gastrectomy was performed. Case 2: A 78-year-old male with gastric cancer and hepatic multiple metastases. Abdominal CT scan before operation did not reveal the hepatic metastasis. In the operation for distal gastrectomy, we found multiple metastases on the surface of the liver. Continuous systemic infusion of low-dose CDDP (20 mg/day) and 5-FU (1,000 mg/day) was performed. This infusion chemotherapy, CDDP and 5-FU, was continued for 5 days and discontinued for 2 days. One month after the chemotherapy, Liver metastases had almost disappeared. Case 3: A 73-year-old male had received a distal gastrectomy based on the diagnosis of gastric cancer. The tumor marker, CA19-9, immediately decreased after the operation, but had increased again. He was treated with a combination chemotherapy of TS-1 and CDDP. The treatment consisted of 4 weeks of TS-1 administration (100 mg daily) followed by a 2-week break. CDDP of 10 mg/day was infused intravenously (day 1-5). Four weeks after the infusion, CA19-9 had returned to almost normal. We conclude that the combination chemotherapy of 5-FU (or TS-1) and CDDP might be an effective treatment for advanced and metastatic gastric cancer.

The effectiveness of chemotherapy for metastatic gastric cancer has been already revealed. But a standard chemotherapy has not been established yet. New agents such as TS-1, CPT-11 and taxanes are improving the response rates and also the survivals for gastric cancer. Including these new drugs, several randomized phase III trials are ongoing in Japan. In the near future, the candidate for standard resume will be sent abroad. In this article, we described the current state of CPT-11 combined chemotherapy for gastric cancer. Among various CPT-11- combined chemotherapy, CPT-11 + TS-1 is the most effective and less toxic treatment.

Mitomycin C (MMC) in combination with infusional 5-fluorouracil (5-FU) is a well-tolerated active combination therapy for advanced gastric cancer. Pegylated liposomal doxorubicin (Caelyx) has been combined with this regimen in a phase I study exhibiting promising activity in patients with upper gastrointestinal tumors. In the present study, we investigated activity and tolerability of this three-drug regimen in patients with gastric cancer. Patients with advanced or metastatic gastric cancer were recruited to receive weekly infusional 5-FU (2000 mg/m2) mixed with sodium folinic acid (FA; 500 mg/m2) in one pump (days 1, 8, 15, 22, 29, 36). On days 1 and 29, Caelyx (20 mg/m2) was given as a 1-h, and MMC (7 mg/m2) was applied as bolus injection on days 8 and 36. Treatment courses were repeated on day 57. Twenty-seven patients with a median age of 66 years were recruited in a single center; 56% had histologically proven peritoneal carcinomatosis and 26 patients are evaluable for toxicity. Common Toxicity Criteria of the National Cancer Institute grade 3 toxicity was recorded in 34% of the patients (anemia 12%, leukocytopenia 8%, febrile neutropenia 4%, thrombocytopenia 12%, nausea 15%, diarrhea 8% and mucositis 4%). One patient developed hemolytic-uremic syndrome. One complete (5%) and eight partial responses (42%) were observed in 19 patients evaluable for response according to WHO criteria. Seven patients had no change (37%) and three (16%) progressive disease. Six patients with peritoneal carcinomatosis not amenable to WHO response assessment had progression-free intervals between 8 and 21 months. Median survival for all patients was 14.7 months and median time to progression was 8.4 months. We conclude that this new three-drug combination regimen yields a promising overall response rate (47%) in patients with gastric cancer despite the inclusion of a majority of elderly patients at moderate or high risk of death in this trial. Its safety and good tolerability as established in the phase I trial was confirmed.

Docetaxel (T) and capecitabine (X) are active agents against gastric cancer with synergistic antitumor effects. We conducted the current phase II study to assess the response rate and toxicity of combination TX regimen in patients with metastatic gastric cancer. Eligible patients were treated with docetaxel (36 mg/m2 intravenously) on days 1 and 8 and capecitabine (1000 mg/m2 orally twice a day) on days 1-14 of a 3-week schedule until progression occurred. From December 2001 to May 2003, 55 patients with median age of 54 years (range, 22-73 years) were enrolled; 47 patients had measurable lesions. A total of 358 courses of treatment were given, with a median of 5 (range, 1-22+) per patient. Objective responses were documented in 19 of 47 patients with measurable lesions (response rate, 40.4%; 95% confidence interval [CI], 25.9-54.9), with the median response duration of 5.6 months (range, 2.1-13.6+). At a median follow up of 15.9 months for all of 55 study patients, the median time to progression and survival were 4.5 months (95% CI, 3.4-5.6) and 12.0 months (95% CI, 7.5-16.6), respectively. Hematologic toxicities were mild to moderate, and the observed grade 3 nonhematologic toxicities, the most frequent of which was stomatitis, were generally manageable. Four patients experienced pneumonitis, but all of them responded to steroid treatment. The TX regimen was relatively well tolerated and effective against metastatic gastric cancer, with the added advantage of being an outpatient regimen.

We aim to clarify beneficial effect of pre-operative radiation with chemotherapy in highly advanced gastric cancer patients, evaluating histological response, toxicity and patients' quality of life (QOL). We used pre-operative radiation with S-1 and low-dose cisplatin to treat 8 patients with highly advanced gastric cancer (clinical stage IV) in a pilot study. Clinical staging after therapy showed 5 PRs (partial response), 2 NCs (no change), and 1 PD (partial disease) following evaluation of the primary tumor and suspicious metastatic lesions in the lymph nodes, esophagus, liver, and peritoneum, for a response rate of 62.5% (5/8 cases). Of 8 patients, 6 underwent surgery, and 2 of these 6 patients had a histologically complete response (grade 3 effect) and 3 patients had a partial response (grade 2 effect), suggesting that a high histological response (5/6 cases; 83.3%) is expected by the chemoradiation. The survival analysis showed that 5 out of the 8 patients died within 10 months after initiating therapy, while 3 patients are alive without recurrence at 15, 18, and 30 months after therapy, suggesting a relatively good outcome for clinical stage IV gastric cancer. All cases showed grade 2-4 bone marrow suppression toxicity and/or grade 0-2 gastro-intestinal toxicity, while 5 out of 8 patients (62.5%) showed improvement in appetite loss at the end of the therapy, indicating that the patients' quality of life (QOL) was preserved. Chemoradiation may be a powerful regimen for obtaining histological response with tolerable toxicity and improved QOL in highly advanced gastric cancer patients.

Although many randomized trials of chemotherapy for metastatic gastric cancer have been reported during the past two decades, no standard regimens worldwide have been established yet. Reference arms vary depending on the region and cultural differences. To date, a combination of 5-fluorouracil (5-FU) and cisplatin is most widely used. However, no confirmation of survival advantage over single-agent 5-FU in a randomized trial has been proved yet, and there remain limitations of efficacy results in older-generation regimens. Recently developed new agents such as irinotecan, taxanes (paclitaxel and docetaxel), and new oral fluorouracil (S-1 and capecitabine) provided more promising results: a response rate over 50% and median survival time (MST) over 10 months in their preliminary combination studies. These newer combination regimens are now being investigated in various randomized phase III studies, which will clarify whether the newer-generation regimens provide survival advantage over older-generation regimens. The MST of the new standard should exceed 11 months to be considered a definite improvement, and overall survival seems to be a more desirable primary end point than progression-free survival in a randomized trial. Molecular targeting agents are another concern to improve the treatment outcomes of this disease and are now under investigation in combination with conventional cytotoxic agents. Both clinical and biological research will be more important in future studies.

An open-label randomised comparison of efficacy and tolerability of irinotecan plus high-dose 5-fluorouracil (5-FU) and leucovorin (LV) (ILF) with etoposide plus 5-FU/LV (ELF) in patients with untreated metastatic or locally advanced gastric cancer. One cycle of ILF comprised six once-weekly infusions of irinotecan 80 mg m(-2), LV 500 mg m(-2), 24-h 5-FU 2000 mg m(-2), and ELF comprised three once-daily doses of etoposide 120 mg m(-2), LV 300 mg m(-2), 5-FU 500 mg m(-2). In all, 56 patients received ILF and 58 ELF. Median age was 62 years, Karnofsky performance 90%, and disease status was comparable for both arms. The objective clinical response rates after 14 weeks treatment (primary end point) were 30% for ILF and 17% for ELF (risk ratio (RR) 0.57, 95% confidence interval (CI) 0.29-1.13, P = 0.0766). Overall response rates over the entire treatment period for ILF and ELF were 43 and 24%, respectively (RR 0.56, 95% CI 0.33-0.97; P = 0.0467). For ILF and ELF, respectively, median progression-free survival was 4.5 vs 2.3 months, time to treatment failure was 3.6 vs 2.2 months (P = 0.4542), and overall survival was 10.8 vs 8.3 months (P = 0.2818). Both regimens were well tolerated, the main grade 3/4 toxicities being diarrhoea (18%, ILF) and neutropenia (57%, ELF). The data from this randomised phase II study indicate that ILF provides a better response rate than ELF, and that ILF should be investigated further for the treatment of metastatic gastric cancer.

Oxaliplatin plus fluorouracil/folinic acid (5-FU/FA) every 2 weeks has shown promising activity in advanced gastric cancer. This study assessed the efficacy and safety of weekly oxaliplatin plus 5-FU/FA (FUFOX regimen) in the metastatic setting. Patients with previously untreated metastatic gastric cancer received oxaliplatin (50 mg m(-2)) plus FA (500 mg m(-2), 2-h infusion) followed by 5-FU (2000 mg m(-2), 24-h infusion) given on days 1, 8, 15 and 22 of a 5-week cycle. The primary end point of this multicentre phase II study was the response rate according to RECIST criteria. A total of 48 patients were enrolled. Median age was 62 years and all patients had metastatic disease, with a median number of three involved organs. The most common treatment-related grade 3/4 adverse events were diarrhoea (17%), deep vein thrombosis (15%), neutropenia (8%), nausea (6%), febrile neutropenia (4%), fatigue (4%), anaemia (4%), tumour bleeding (4%), emesis (2%), cardiac ischaemia (2%) and pneumonia (2%). Grade 1/2 sensory neuropathy occurred in 67% of patients but there were no episodes of grade 3 neuropathy. Intent-to-treat analysis showed a response rate of 54% (95% CI, 39-69%), including two complete responses. At a median follow-up of 18.1 months (range 11.2-26.2 months), median survival is 11.4 months (95% CI, 8.0-14.9 months) and the median time to progression is 6.5 months (95% CI, 3.9-9.2 months). The weekly FUFOX regimen is well tolerated and shows notable activity as first-line treatment in metastatic gastric cancer.

The role of hepatic resection for metastatic gastric cancer is less well defined due to the tendency of gastric cancer to widely metastasize. The purpose of this study is to examine the beneficial effect of hepatic resection in patients with metastatic gastric cancer. The clinicopathologic features and long-term results of 11 patients who underwent hepatic resection for metastatic gastric cancer from January 1988 to December 1996 at Seoul National University Hospital were analyzed retrospectively. All resected hepatic metastases were solitary lesions. Among eight patients with synchronous hepatic metastases, one patient with early gastric cancer and lymph node metastases (T1N2M1) remained alive for 8 years 6 months after hepatic resection without recurrence. Among three patients with metachronous hepatic metastases, two patients with advanced gastric cancer and lymph node metastases (T3N2MO, T2N1MO at the initial operation, respectively) survived 8 years 6 months and 3 years after hepatic resection, respectively. Median survival times of synchronous and metachronous hepatic metastases were 13.0 and 74.3 months, respectively. In solitary hepatic metastatic lesions from gastric cancer, surgical resection should be considered as one of the treatment options.

To investigate the efficacy and safety of combining weekly paclitaxel with weekly 24-hour infusion of high-dose 5-fluorouracil (5-FU) and leucovorin (LV, folinic acid) in the treatment of patients with advanced gastric cancer. Patients with histologically confirmed recurrent or metastatic gastric cancer were studied. Paclitaxel 80 mg/m2 3-hour intravenous infusion was given on days 1, 8, and 15, and high-dose 5-FU 2,600 mg/m2 plus LV 300 mg/m2 24-hour intravenous infusion (HDFL) was given on days 2, 9, and 16, repeated every 4 weeks. Between August 1997 and August 2003, 30 patients were enrolled. The median age was 58 years (range: 37-70). Eighteen patients (60.0%) had recurrent or metastatic disease and 12 patients had de novo metastatic disease. Among the 27 patients evaluable for tumor response, 2 achieved complete response and 9 achieved partial response, with an overall response rate of 40.7% (95% confidence interval, CI: 22-61%). Eleven of the 21 patients without prior exposure to HDFL-containing regimens responded (response rate: 52.4%, 95% CI: 29-74%), while none of the 6 patients who had previously failed HDFL-containing regimens responded (p value = 0.054 by Fisher's exact test). All 30 patients were evaluated for survival and toxicities. Median time to progression and overall survival were 6 and 10 months, respectively. Major grade 3-4 toxicities were neutropenia in 12 patients (40.0%), diarrhea in 10 patients (33.3%), and stomatitis in 3 patients (10.0%). Grade 1-2 and 3-4 paclitaxel-related neuropathy developed in 16 (53.3%) and 2 (6.7%) patients, respectively. None of the patients discontinued protocol treatment because of paclitaxel-related neuropathy or developed HDFL-related hyperammonemic encephalopathy. This paclitaxel-HDFL regimen is effective and well tolerated in the treatment of advanced gastric cancer.
