ABSTRACT

BACKGROUND: The efficacy of systemic chemotherapy for peritoneal dissemination of gastric cancer remains unclear. The efficacy of weekly paclitaxel in combination with doxifluridine (5'-DFUR) in gastric cancer patients with malignant ascites was evaluated. PATIENTS AND METHODS: Patients with histologically confirmed gastric cancer with ascites were eligible. The treatment consisted of paclitaxel intravenously (i.v.) administered at 80 mg/m(2) on days 1, 8 and 15 every 4 weeks, and doxifluridine administered orally at 533 mg/m(2) on days 1-5 every week. The response rate for patients with ascites was determined based on the Japanese Classification of Gastric Carcinoma. Also, the concentration of paclitaxel in the ascites was measured. RESULTS: Twenty-four patients were investigated. The response rate (RR) was 41.7%, including complete remission (CR) and partial remission (PR) in 4 and 6 patients, respectively. The concentration of paclitaxel in the ascites was maintained between 0.01 µM and 0.05 µM until 72 hours. The median overall survival (OS) was 215 days, and 1-year survival rate was 29.2%. No severe toxicity was noted. CONCLUSION: Weekly paclitaxel in combination with doxifluridine is effective for gastric cancer patients with malignant ascites with an acceptable toxicity profile.

ABSTRACT

We have treated 14 advanced and metastatic colorectal cancers with irinotecan (CPT-11) plus fluorouracil (5-FU) and l-leucovorin (l-LV) combination chemotherapy. The 14 patients consisted of 8 males and 6 females with a mean age of 65 years. We diagnosed adenocarcinoma of the colon in 10 patients and of the rectum in 4 patients. Four patients had liver metastases, five had lung metastases, and one had both, while one had lung and lymph node metastases, two had lymph node metastases and one had a local recurrence. The chemotherapy consisted of CPT-11 100 mg/m(2) div, as a 150-minute infusion, simultaneously l-LV 10 mg/m(2) div, as a 30-minute infusion, followed by 5-FU 500 mg/m(2) iv, as a bolus injection. This treatment was administered weekly for 2 weeks followed by a 2-week rest period and repeated every 4 weeks. All patients received this regimen as first-line chemotherapy. All patients were evaluated for efficacy 1 CR, 2 PR, 9 SD, and 2 PD. The overall response rate was 21.4% with a median time to progression of 8.1 months and a median survival time of 18.6 months. Grade 3 nausea, diarrhea and the suppression of white blood cells were seen in 3 patients, respectively. All other adverse reactions were mild (grade 1 or 2). Except for one patient,residual patients were able to receive the systemic chemotherapy on schedule. CPT-11/5-FU/l-LV combination chemotherapy appears to be effective first-line chemotherapy for advanced and metastatic colorectal cancer.

ABSTRACT

We successfully treated four advanced colorectal cancers with irinotecan (CPT-11) plus 5-fluorouracil (5-FU) and l-leucovorin (l-LV) combination chemotherapy. We diagnosed moderately-differentiated adenocarcinoma of the colon in two patients and of the rectum in two patients. We recognized lymph node metastases in one patient and liver metastases in three patients at the time of operation. After excision for a lesion of the colon or the rectum, all patients underwent a 2-week chemotherapy regimen (CPT-11 100 mg/m2/week + 5-FU 500 mg/m2/week + l-LV 10 mg/m2/week). The effect was PR in all patients. The progressive free survival time was 9.5 months and survival time ranged 5-18 months. Grade 3 diarrhea and leukopenia were seen in one patient. All other adverse reactions were mild (grade 1 or 2). CPT-11/5-FU/l-LV combination chemotherapy appears to be effective for advanced and metastatic colorectal cancer.

ABSTRACT

Primary malignant tumors of the small intestine are rare. Malignant gastrointestinal stromal tumors are the third most common neoplasm among primary malignant small bowel tumors. A 56-year-old woman was admitted to our hospital because of appetite loss and dyspnea with movement. On admission, physical examination revealed severe anemia in her conjunctiva and a tumor in her left abdomen. Her hemoglobin level was 6.2 g/dL and other laboratory data were normal. Abdominal ultrasonograms and computed tomograms revealed a 55 x 70-mm heterogeneous mass and multiple low-density masses in the liver. Superior mesenteric arteriograms revealed a hypervascular tumor fed by the jejunal arteries. A malignant gastrointestinal stromal tumor arising from the jejunum with liver metastases was suspected. Partial resection of the affected jejunum and left trisegmentectomy of the liver were performed. The resected primary tumor was 120 x 45 x 65 mm. The tumor was mainly submucosal, but extended outside the jejunum; it was elastically firm and multiloculated. A small ulcer was seen on the mucosal side. The metastatic liver tumors were solid or cystic with diameters of 20 to 40 mm. Histopathological examination revealed that the tumors were characterized by fascicular proliferation of spindle-shaped cells. Immunohistochemical staining was positive for CD34 and c-kit, and negative for S-100 protein and smooth muscle actin. This case was a malignant gastrointestinal stromal tumor originating in the jejunum with liver metastases. The primary tumor and liver metastases were successfully resected simultaneously.
