We report 3 cases in which palliation was achieved with every-other-day administration of TS-1 for recurrent or non-curative advanced gastric carcinoma that had resulted in obstructive jaundice. Two patients had received MTX-5-FU chemotherapy as first-line therapy and showed progressive disease, presenting with obstructive jaundice 6-24 months later. One of them experienced obstructive jaundice 2 months after surgery. After lowering serum bilirubin via per-cutaneous transhepatic biliary drainage (PTBD), TS-1 was given not in full dose but every other day based upon Shirasaka's theory, as well as for fear of further liver damage. Palliation in terms of long NC and/or decreased serum CEA level persisted for 4-14 months without severe liver dysfunction. Other side effects of the drug were negligible. Shirasaka's theory stresses the difference in proliferation cycles between cancer cells and normal tissue cells (GI tract, bone marrow, etc.); therefore, with every-other-day administration of chemotherapeutic agents, the cytotoxic effects against tumors would be augmented while the adverse reactions in normal cells could be reduced. The present experience seems to support the theoretical and clinical feasibility of every-other-day TS-1 administration for unresectable gastric cancer.

We retrospectively evaluated the efficacy of chemotherapy regarding symptom control, toxicity and discharge rate in 39 patients with gastric or colorectal cancer. Treatment consisted of TS-1 (n = 16), TS-1 + CPT-11 (n = 8), CDDP + CPT-11 (n = 5), paclitaxel (n = 8) and MTX + 5-FU (n = 4) for gastric cancer and 5-FU + l-leucovirin (n = 6), 5-FU + CPT-11 (n = 5), MMC + CPT-11 (n = 8) and 5-FU protracted continuous infusion (n = 5) for colorectal cancer. The rates of symptom improvement were the following: pain 60% (10/15), general fatigue 56% (5/9) and abdominal fullness 53% (8/15). 87% (34/39) of the patients were discharged from hospital and continued chemotherapy as outpatients grade 3 toxicities were the following: anemia 10.3%, nausea and/or vomiting 7.7%, diarrhea 5.1%. There was no treatment related death. The rates of outpatient based treatment duration improvement were the following: gastric cancer: 47.6%, colorectal cancer: 72%. These data suggest that these treatments for gastric and colorectal cancer are safe and improve the patients' QOL.

A 67-year-old female was admitted to our hospital in May, 2001 for examination. She was diagnosed with advanced gastric cancer that was inoperable due to peritoneal dissemination. Seventeen courses of sequential MTX and 5-FU therapy, and 2 courses of TS-1 plus CDDP were carried out. A partial response (PR) and prolonged NC were obtained after these chemotherapies. However, pleural effusion and ascites appeared again, and we diagnosed progressive disease. As a third line chemotherapy for this patient, paclitaxel (TXL) was administered. Treatment consisted of two 3-week courses of paclitaxel 70 mg per m2 on day 1 of each week, with a 1-week break between the courses. Two weeks after the start of this therapy, pleural effusion and ascites had completely disappeared. Paclitaxel is considered to be promising for advanced gastric cancers, as second or third line chemotherapy with paclitaxel for patients with inoperable gastric cancer seems to be effective in improving QOL.

There have been few effective chemotherapeutic regimens for advanced gastric cancer with liver and intra-abdominal lymph node metastasis. A 78-year-old male patient was admitted to our hospital because of anorexia and abdominal discomfort. Gastroendoscopy showed a type 4 advanced gastric cancer in the antrum of the stomach. Histological study of biopsy specimens from the tumor revealed poorly differentiated adenocarcinoma. Examination by computed tomography and ultrasonography showed swollen paraaortic lymph nodes and liver metastasis. He was diagnosed as having advanced gastric cancer with liver and lymph node metastasis. This patient was treated weekly with an intraarterial 5-FU (500 mg) and MTX (100 mg) including AT-II by subcutaneously implanted port system placed into the celiac artery. Furthermore, he was administered tegafur/uracil (400 mg/day) 5 days weekly as pharmacokinetic modulating chemotherapy (PMC). After ten courses of treatment with PMC, the liver and lymph node metastases were reduced in size. This therapy was considered to be an effective treatment for advanced gastric cancer with liver and lymph node metastasis. The theoretical purpose of hypertensive chemotherapy used together with injection of angiotensin-II is to increase the delivery of anticancer drug to the target tumor tissue by increasing the blood flow in the tumor. We conclude that this chemotherapy is effective in cases of advanced gastric cancer with liver and lymph node metastasis from the viewpoints of toxicities, antitumor effect and QOL of the patient.

We report a case of advanced gastric cancer that responded to docetaxel with low-dose 5-FU and cisplatin combination chemotherapy after becoming chemoresistant to M-FLP. A 52-year-old male was diagnosed with type 3 gastric cancer of angulus (poorly differentiated adenocarcinoma) with left neck, Virchow, mediastinal and abdominal lymph nodes metastases. The patient was treated with 5 courses of M-FLP (MTX + 5-FU + LV + CDDP), and the effect of this therapy was PR, but the tumor was chemoresistant to the sixth course of this therapy. After 7 courses of M-FLP, docetaxel (TXT) with low-dose FP (5-FU + CDDP) was administered to the patient as second-line chemotherapy. After 2 courses of TXT with low-dose FP, the gastric cancer and metastatic lymph nodes were remarkably reduced and the effect of this therapy was PR. The toxic events were anemia (grade 2) and leukopenia (grade 3), which were treated with G-CSF. CDDP and 5-FU based regimens are considered as the first-line chemotherapy for metastatic advanced gastric cancer in Japan; however, a second-line chemotherapy has not been established. As in this case, a TXT based regimen is effective and well tolerated therapy as a second-line chemotherapy for metastatic gastric cancer after prior exposure to CDDP and 5-FU.

A 75-year-old man was admitted to our hospital complaining of gastric fatigue. Endoscope and CT scan revealed type 3 gastric cancer with paraaortic lymph nodal metastasis. Histological examination of the endoscopic biopsy revealed poorly differentiated adenocarcinoma. A blood examination and bone marrow biopsy revealed DIC causing bone marrow carcinosis. Chemotherapy with sequential therapy consisting of MTX and 5-FU was performed. Stretch of the fold and flatness of the ulcer were obtained against the gastric primary lesion observed endoscopically. Complete response was obtained against the lymph node around the abdominal aorta. Reduction of low back pain and DIC were observed. He was thus able to be discharged and sequential therapy was performed again over 2 months in outpatient care.

Peritoneal dissemination is a major event in the development of gastric cancer. However, most patients with it have been excluded from clinical studies because they rarely have measurable lesions. We conducted an analysis to evaluate the efficacy and feasibility of modified pharmacokinetic modulating chemotherapy, for gastric cancer patients with peritoneal dissemination. Between May 2002 and April 2004, 10 patients were treated by modified pharmacokinetic modulating chemotherapy. This analysis was based on 10 consecutive chemotherapy-naive patients with confirmed peritoneal dissemination. This therapy regimen was repeated with a weekly schedule of MTX 100 mg/body, given as intraarterial infusion 1 h prior to a 24-hr infusion of 5-FU 500 mg/body. Simultaneously, enteric-coated tegafur/uracil (400 mg) was administered every day. The one-year overall survival rate was 50. 0%. The median survival time was 311 days. Grade 1 stomatitis and Grade 1/2 oral dryness were involved in 40% of the cases. No patient had to discontinue this therapy because of complications. Objective improvement of ascites was seen in all patients, and all patients could be treated at outpatient clinics. This regimen may be well-tolerated and of clinical benefit for patients with peritoneal dissemination of gastric cancer.

We report a 47-year-old female patient who was suffering from severe DIC due to multiple bone metastases. This patient was treated weekly with an intraarterial 5-FU (500 mg) and MTX (100 mg) including AT-II by a subcutaneously implanted port system placed into her abdominal aorta. Furthermore, she was administered tegafur/uracil (400 mg/day) 5 days weekly for pharmacokinetic modulating chemotherapy (PMC). After three courses of PMC treatment, DIC was resolved and the tumor marker was reduced. However, after 22 courses of this regimen, DIC suddenly recurred. As second line chemotherapy, we then administered paclitaxel (80 mg) in place of CDDP. After five courses of this second line chemotherapy, DIC recovered and the tumor marker was again decreased. We concluded that this chemotherapy is effective for advanced gastric cancer complicated with bone metastasis and DIC from the standpoint of toxicities, antitumor effect and QOL of the patient.

A 62-year-old male patient with paraaortic lymph node metastasis of type 2 gastric cancer underwent distal gastrectomy with partial resection of transverse colon. MTX/5-FU sequential therapy was performed 5 times as adjuvant chemotherapy. After that TS-1 was administered on a 4-week dosing regimen with a 2-week interval between sessions. The patient regimen was discontinued temporarily because of thrombocytopenia. Therefore the schedule was changed to a 2-week dosing regimen with a 1-week interval between sessions at 2 years after operation. Paraaortic lymph node size was then checked by abdominal CT one or two times a year. The size showed no change for 3 years after operation. Then, 3 years and 3.5 years later, CT follow-up did not show paraaortic lymph node or other organ metastasis. We judged the effect of TS-1 was CR. Now the patient is disease-free at 4 years after operation.

Curative resection is considered to be a standard therapy for gastric cancer with localized peritoneal metastases. For tumors with diffuse dissemination, chemotherapy may play a major role, however, the benefits of reduction surgery and standard chemotherapy have not yet been clarified. Median survival time after reduction surgery was reported to be 4-13 months for patients diagnosed by surgery and/or CT and 5-6 months for chemotherapy for those diagnosed by CT alone. Reduction surgery has a high risk, with a morbidity of 12-44% and a mortality of 3-14%. Palliative surgery should be indicated for stenosis or bleeding due to primary tumors. 5-FU, MTX-5-FU, TS-1, paclitaxel, and their combination are candidates for practice and clinical trials. It is important to evaluate the severity of peritoneal dissemination by diagnostic laparoscopy or laparotomy for decision making.
