Irinotecan (CPT-11) is a novel water-soluble, semisynthetic derivative of camptothecin, with inhibitory effects on mammalian DNA topoisomerase I, high cytotoxic activity in vitro and anticancer activity in animal models. Fifty-nine patients, with cancer refractory to conventional therapy, were entered in this phase I study, using a weekly schedule administration. A total of 304 weekly doses were administered at dose levels ranging from 50 to 145 mg/m2 (30-90 min i.v. infusion). Leukoneutropenia and diarrhea were the dose-limiting toxicities and appeared to be dose related, reversible and noncumulative. However, interpatient variability of toxic effects was substantial. Prolongation of the infusion time from 30 min to 90 min appeared to decrease the diarrhea. Other toxicities included moderate emesis, asthenia, alopecia, abdominal pain, and anemia. CPT-11 plasma disposition was bi- or triphasic with a terminal half-life of 9.3 h. CPT-11 area under the plasma concentration versus time curves increased linearly with dose (r = 0.47, P < 0.01). The active metabolite area under the plasma concentration versus time curve correlated significantly with that of CPT-11, but not with that of CPT-11 dose. Both CPT-11 and 7-ethyl-10-hydroxycamptothecin areas under the plasma concentration versus time curve correlated significantly with leukoneutropenia and diarrhea. One partial and 4 minor responses were observed at dose levels of 130 and 145 mg/m2. Using this weekly schedule, recommended doses for phase II studies are 100 mg/m2 in high risk patients and 115 mg/m2 in others.

A nationwide multi-center cooperative phase II clinical study of irinotecan hydrochloride (CPT-11) was conducted to evaluate its efficacy in intractable malignant lymphoma and acute leukemia. In malignant lymphoma, one course of CPT-11 consisted of intravenous drip infusion at a dose of 40 mg/m2 once daily for 3 consecutive days, performed once a week. In acute leukemia, one course of CPT-11 consisted of intravenous drip infusion at a dose of 15 to 20 mg/m2 a day twice daily for 7 consecutive days (1 cycle), performed every 2 to 4 weeks. Among the 79 patients with malignant lymphoma and 50 patients with acute leukemia enrolled in the study, 66 and 41 patients, respectively, completed treatment. These patients had all undergone chemotherapy prior to treatment. Among the malignant lymphomas, the response rate in non-Hodgkin's lymphoma (NHL), including 9 CRs, was 42% (26/62, 95% CI: 30-54%); of these there was a response rate of 39% (5/13), including 1 CR, in adult T-cell leukemia (ATL) as well. In Hodgkin's disease (HD), on the other hand, there were no cases in which efficacy was demonstrated (0/4). The overall response rate in malignant lymphoma was 39% (26/66), and the response rate even among the recurrent intransigent cases was 42% (16/38). The 50% survival time (MST) in the 74 eligible cases of malignant lymphoma was 153 days. In acute leukemia, on the other hand, partial remission was observed in 2 of 17 cases (12%) of acute lymphocytic leukemia (ALL), but no cases of remission were observed in the 24 patients with acute myelogenous leukemia (AML). The overall remission rate in acute leukemia was 5% (2/41, 95% CI: 1-14%). The principal adverse effects were myelosuppression in malignant lymphoma and gastrointestinal symptoms, including diarrhea, nausea/vomiting, anorexia and abdominal pain, in both malignant lymphoma and acute leukemia, and there was little organ damage to the heart, liver or kidney. Myelosuppression and gastrointestinal adverse effects were severe in some of the patients, so caution is required. Based on the above findings, CPT-11 appears to be efficacious in the treatment of non-Hodgkin's lymphoma.

A case of AFP-producing gastric cancer successfully treated with CPT-11 and cisplatin combined therapy is reported together with a review of the literature. A 52-year-old male was admitted with complaints of upper abdominal pain and body weight loss. Gastric cancer with multiple liver metastases was diagnosed based on endoscopy and computed tomography findings. The patient's serum AFP level was 697,100 ng/ml and a biopsy specimen showed AFP-positive tumor cells immunohistochemically. He was treated with a combination chemotherapy consisting of CPT-11 (70 mg/m2) on day 1 and 15, and cisplatin (80 mg/m2) on day 1, repeated every 4 weeks. The primary lesion of the stomach and the liver metastases were remarkably reduced, and the serum level of AFP decreased to 18 ng/ml after 5 cycles of this treatment. No severe side effects were seen during this treatment. This result suggests that combination chemotherapy consisting of CPT-11 and cisplatin may be effective and safe for patients with AFP-producing gastric cancer with multiple liver metastases.

We report a rare case of small cell carcinoma of the stomach with metastasis to the liver and invasion of the pancreas, which was associated with acute peritonitis due to perforation of the stomach. CPT-11/CDDP chemotherapy achieved a partial response. A 60-year-old man suddenly developed abdominal pain and visited the emergency room. We diagnosed acute peritonitis due to perforation of the digestive tract because CT scan showed free air in the abdominal cavity. An emergency operation was performed with an omental patch for closing the perforated hole in the stomach. Excisional biopsy was performed to the small liver nodule. Histological findings showed that the liver nodule was metastasis from small cell carcinoma. There was no finding from the thoracic CT scan, but gastroscopy revealed a giant tumor, which was diagnosed as small cell carcinoma in histology. Therefore, we diagnosed small cell carcinoma of the stomach with liver metastasis and invasion of the pancreas. After operation, one course of FP chemotherapy was performed, but the liver metastasis increased in size. Then we changed to CPT-11/CDDP chemotherapy as second-line therapy, and achieved partial remission (PR) of both the liver metastasis and gastric tumor.

A 62-year-old woman complained of abdominal pain and diarrhea from February 2, 2002. She was diagnosed with advanced cecal cancer with simultaneous multiple liver metastases. The serum level of CA 19-9 was 420 U/ ml. Ileoceal resection with D3 lymphnode dissection. The replacement of reservoir for hepatic arterial infusion (HAI) was performed on February 2, 2002. As the dissemination was seen near the mesocolon at laparotomy, we could resect all together. Pathological examination demonstrated II, 5.0 x 2.5 cm, mod, se, INFgamma, ly(1), v(1), n(2), stage IV. Systemic l-leucovorin/5-fluorouracil (l-LV/5-FU) + HAI of weekly high-dose 5-FU combination therapy was initiated at postoperative 14 days. The serum CA 19-9 level decreased immediately but was not within the normal range. On abdominal computed tomography (CT), liver metastatic lesions decreased 9 9% on May 27, 2002 and disappeared on August 26, 2002. Though there were no signs of recurrence, the serum CA 19-9 level elevated as of October, 2002. Since the hepatic artery was occluded, HAI was discontinued on November 28, 2002. The serum CA 19-9 level elevated inspite of the continuation of the l-LV/5-FU therapy which we increased an amount of 5- FU. Thus, we changed low-dose irinotecan (CPT-11)/cisplatin (CDDP) therapy. The serum level of CA 19-9 decreased gradually and got with in normal range on March, 2004. It did not elevate since then. Low-dose CPT-11/CDDP therapy may be useful for patients with advanced colon cancer thought to be resistant to 5-FU as second-line chemotherapy.

A 50-year-old man was admitted because of right lateral abdominal pain, easy fatigue and anemia. An endoscopic examination revealed advanced ascending colon cancer, and abdominal CT scan demonstrated enlarged metastatic lymph nodes of superior mesenteric arterial circumference. The Serum CEA rose considerably. The preoperative diagnosis was cStage IV (SS, N(4), P(0), H(0), M(-)), and right colectomy was performed on March 2, 2005. The metastatic lymph nodes around the superior mesenteric arterial root macroscopically remained. From the 20th postoperative day, we started combination chemotherapy using S-1 plus CPT-11 as one course for three weeks. S-1 (120 mg/body/day) was orally administered for 2 weeks continuously, and CPT-11 (80 mg/m(2)) was done intravenously on day 1 and 8. Serum CEA was normalized in the middle of 3 courses. Moreover, after 13 courses, a complete response (CR) was noted on the follow-up abdominal CT scan. No severe side effect more than grade 2 was observed, there was no interruption of the dosage, and PS was sufficiently maintained kept enough through this combination chemotherapy. The course has been without metastasis, recurrence and a rise of serum CEA now in the 16th postoperative month. S-1/CPT-11 combination chemotherapy is a promising and effective cure for unresectable progressive recurrent colorectal cancer in future.

A 63-year-old man with abdominal pain was diagnosed as locally advanced pancreatic tail cancer and gastric cancer with peritoneal metastasis based on computed tomography (CT) and gastrointestinal series. Preoperative serum CA19- 9 was 1,357 U/mL. During laparotomy, peritoneal dissemination was observed and confirmed pathologically. An ileoileostomy was performed and peritoneal tissue was submitted to a chemosensitivity test. Based on the chemosensitivity test, CPT-11 (50 mg/body), 5-FU (750 mg/body), and Leucovorin (375 mg/body) were administered intravenously once a week for 3 weeks with a 1-week rest as 1 course. The patient received 9 courses of chemotherapy until progressive disease. Stable disease in tumor size was observed and serum CA19-9 level dropped to 81 U/mL. He remained well without any symptoms and pursued normal activity for 15 months. He died of peritoneal dissemination 26 months after diagnosis. Chemosensitivity test-guided chemotherapy seems to be an effective regimen as individualized chemotherapy for advanced pancreatic and gastric cancer.

A 54-year-old woman visited our hospital with a chief complaint of lower abdominal pain and melena. The patient was diagnosed with sigmoid colon cancer using colonoscopy. Abdominal CT revealed metastases to para-aortic lymph node, so our diagnosis was unresectable sigmoid colon cancer. She underwent a transverse colostomy to avoid stenosis. Two weeks after surgery, she underwent a 1-week chemotherapy regimen (CPT-11 80 mg/m(2)/week+5-FU 2,000 mg/m(2)/week+l-LV 250 mg/m(2)/week) modified AIO regimen combined irinotecan for 3 weeks, followed by a 1-week rest interval as one course. Throughout the period of treatment, there was no adverse event, and this regimen has been maintained for 5 courses. After 5 courses of chemotherapy, primary tumor and metastases to para-aortic lymph nodes were remarkably reduced on colonoscopy and abdominal CT. So, she could undergo curative resection. Pathological efficacy was Grade 3, a complete response. This combination therapy may well be useful for advanced colon cancer patients.

Here we report a rare case with perforation of gastric cancer responding to chemotherapy. The patient was a 74- year-old male who underwent abdominal ultrasonography and contrast CT because of body-weight lost and poor appetite in June, 2004 and whose lymph node(LN)swelling was seen in the level from the hepatic to the renal hilum. A gastric wall irregularity was also seen. We suspected gastric cancer with LN metastasis and carried out upper gastrointestinal endoscopy. Then it demonstrated type 2 advanced gastric cancer from the upper to the middle body. The pathological diagnosis of gastric tumor was poorly-differentiated adenocarcinoma containing por 2, tub 1, and pap. The patient was treated with S-1, CDDP and CPT-11 and remained ambulant. After completion of 1 course of chemotherapy, he complained of intense abdominal pain, so we carried out upper gastrointestinal endoscopy and found perforation in the stomach at the same location as the gastric cancer. Emergency total gastrectomy was performed at once. The histopathological finding showed disappearance of the cancer cell not only in the stomach but also accessory LN. Because the remnant LN metastasis was seen in the hepatic hilum at abdominal contrast CT after operation, S-1 was administered to the patient as 60 mg/m2/day in ambulant. Now, over 40 months after the operation, the patient has been alive with good performance status and disappearance of LN metastasis.

We have experienced a rare case of primary duodenal carcinoma with perforation of the duodenum. Combined CPT- 11, CDDP and DOC chemotherapy achieved a partial response. A 54-year-old man with serious abdominal pain visited our hospital with a diagnosis of acute peritonitis due to perforation of digestive tract on CT scan. An emergency operation was performed with patch for perforation of the duodenum. Endoscopic examination and biopsy after surgery showed duodenal adenocarcinoma. Abdominal CT scan revealed metastasis to the periaortic lymph nodes. Therefore, we diagnosed primary duodenal carcinoma with metastasis to the periaortic lymph nodes. Combined CPT-11, CDDP and DOC chemotherapy were performed. After two courses, endoscopic examination and biopsy showed primary lesion of the duodenum had disappeared. Metastatic lymph nodes were reduced from CT scan after three courses, and successfully controlled until nine courses. Then regimen was changed to S-1 alone and S-1/CPT-11. The patient remained alive for two years after the operation without tumor progression.
