The results of a phase I--II study of a combination chemotherapy with AAFC and ICRF-159 in advanced adenocarcinoma of digestive origin are presented. Myelosuppression was the dose-limiting toxicity with anemia, leukopenia, and thrombocytopenia. The maximum tolerated dose of AAFC in the combination program was 650 mg/m2 I.V. weekly. ICRF-159 was given in a 3-day course every 3 weeks and the dose was escalated from 125 mg/m2 to 500 mg/m2 daily. Bone marrow toxicity was noticied at the first escalation level and all dose levels were similarly toxic. The results of this combination chemotherapy were: two partial responses in 14 patients with gastric cancer; no responses in nine patients with colorectal cancer; no responses in three patients with pancreatic cancer; and no responses in two patients with biliary tree cancer. In conclusion, AAFC and ICRF-159 combination chemotherapy demonstrated a low level of activity in advanced carcinoma of digestive origin. The peculiar hematologic toxicity found at the low-level dose requires further documentation and could make this drug association suitable for a phase II study in leukemia and/or lymphoma.

Aclacinomycin is a new anthracycline analog of adriamycin and daunomycin. Aclacinomycin contains three sugars. The drug has been studied in 22 cases in a phase 1 type of trial on a schedule 20 mg i.v. every other day up to a total of 300 mg. Toxicity has consisted of myelosuppression, nausea and vomiting, and transient hepatic disturbances. Evidence of clinical activity was observed in several cases including a case of breast cancer and gastric cancer. Although no full patial remissions were recorded, further study is continuing.

Between 1985 and 1990, 50 patients with unresectable liver metastases from colorectal cancer and 34 subjects with metastases from gastric cancer were treated by repeated hepatic arterial infusion chemotherapy employing an implantable prot system. A catheter was inserted into the hepatic artery via the left subclavian artery and was connected to the implantable injection port in each patient. 5-Fluorouracil (5-FU) at 330 mg/m2 per week (167 mg/m2 daily given continuously over the initial 3 months for colorectal cancer), Adriamycin (ADR) at 20 mg/m2 every 4 weeks and mitomycin C (MMC) at 2.7 mg/m2 every 2 weeks were given to all 34 patients with gastric cancer and to 31 of the colorectal cancer patients. The remaining 19 patients with colorectal cancer received 5-FU at 1,000 mg/m2 every week. As a rule the treatment was performed on an outpatient basis. The side effects and complications observed included myelosuppression (23%), hepatic arterial occlusion (21%), and gastroduodenal mucositis (12%), although no major toxicity was encountered. The response rate (CR+PR) among the evaluated patients as determined using CT scans was 67% for colorectal cancer and 73% for gastric cancer. The overall median survival was 12 months and 15 months, respectively. Good local control of liver metastases from the colorectal and gastric cancers was achieved by repeated hepatic arterial infusion chemotherapy employing an implantable port system without the need for hospitalization and without producing major toxicity. Thus, the implantable port system is very useful for the management of patients with unresectable liver metastases.

Etoposide has modest single-agent activity (21% partial response rate) in patients with previously untreated metastatic gastric carcinoma. The use of etoposide in combination with agents like doxorubicin, cisplatin, and 5-fluorouracil with or without leucovorin has been of increasing interest to oncologists. Such combinations have been reported to produce overall response rates as high as 60% to 70%, with complete response rates as high as 20%, in patients with advanced measurable gastric carcinoma. Etoposide-containing regimens have also been used preoperatively in potentially resectable patients. In these studies, approximately 60% of treated patients may be rendered disease-free following resection. Preoperative (neoadjuvant) therapy has not yet been shown in phase III studies to be superior to surgery alone. Significant myelosuppression is the major toxicity of etoposide-based chemotherapy. Such chemotherapy deserves further evaluation in the treatment of gastric cancer.

Idarubicin is one of the new anthracycline analogues. It has a higher therapeutic index than either doxorubicin or daunorubicin in a variety of murine leukemias and solid tumors. The authors performed a multicenter Phase II trial of idarubicin in patients with advanced gastric cancer. Seventeen patients with measurable metastatic disease were entered into the trial and treated with idarubicin at a starting dose of 15 mg/m2. This dose was escalated or reduced according to toxicity. There were no documented responses. The dose-limiting toxicity was myelosuppression. These data did not compared favourably with the data on doxorubicin in the treatment of gastric carcinoma. A conclusion could not be reached on whether idarubicin has minimal activity in the treatment of gastric carcinoma.

The recent successes being achieved with combination chemotherapy regimens, such as FAMTX (fluorouracil [5-FU], doxorubicin, methotrexate), EAP (etoposide, doxorubicin, cisplatin), and ELF (etoposide, leucovorin, 5-FU), strongly indicate that gastric cancer is chemosensitive. With these regimens, objective remission rates of more than 50% were recorded, including approximately 10% complete remissions (CRs). Moreover, some of these CRs were histopathologically confirmed. The finding that locally advanced disease (LAD) and technically unresectable disease could be rendered resectable by preoperative chemotherapy (EAP) was important. Thirty-six patients with LAD had been treated in a phase II trial with preoperative EAP, inducing 24 (70%) overall remissions (two clinical CRs, six pathologic CRs, 16 partial remissions [PRs] in 35 evaluable patients. Twenty-one patients were disease-free after chemotherapy with or without second-look surgery. The median survival time was 18 months for all patients and 24 months for disease-free patients. At 30+ months, 21% of all patients are still living disease-free. The expected survival of patients with unresectable LAD is approximately 4 to 6 months without any treatment and 6 to 9 months with standard chemotherapy. Compared with the latter results, the preoperative use of effective regimens (eg, EAP) seems to improve prognosis of patients with LAD. Moreover, such a multimodal approach may increase the number of long-term survivors among patients with resectable gastric cancer, especially those whose stage indicates a high risk of relapse (stages IIIa or IIIb). However, partly because of the severe toxicities (myelosuppression, nausea/vomiting), a considerable number of patients cannot be treated with these new regimens for the following reasons: Two of three patients with gastrointestinal disease are older than 60 years. Nontumorous diseases of the cardiovascular system, kidney, and others are frequent in this age group and may complicate or even prevent treatment with aggressive regimens. Considering the predominantly palliative treatment intentions in far advanced (metastasized) gastric cancer, regimens with low toxicities and acceptable activity should be preferred. For these reasons, we developed and investigated the combination ELF in a phase II trial in elderly patients (greater than 65 years) and in patients with cardiac risks who could not be treated with anthracyclines. The overall response rate in 51 evaluable patients was 53% (27 of 51) including six clinical CRs (12%). The median remission duration was 9.5 months and the median survival time was 11 months. Tolerability was excellent. Only 16% and 4% of patients, respectively, experienced WHO grades 3 and 4 leukopenia. Nausea/vomiting and mucositis/stomatitis were mild.(ABSTRACT TRUNCATED AT 400 WORDS)

To determine the feasibility and toxicity of combining leucovorin (CF) with a 5-fluorouracil (5-FU) combination chemotherapy regimen currently accepted by many as standard treatment for gastric cancer, CF (500 mg/m2) was administered in combination with the Georgetown 5-FU, doxorubicin, and mitomycin C (FAM) regimen. Thirty-two patients with advanced adenocarcinoma of the stomach were evaluable for toxicity and 26 patients with measurable disease were evaluable for response. Fifty-four percent of patients were previously treated with chemotherapy or radiation therapy. The response rate was 38% (95% confidence interval, 21% to 59%). The median duration of response was 6 months (range, 2 to 23+ months). The estimated median survival time was 6.8 months for patients with measurable disease and 11.5 months for all 32 patients. Although diarrhea is dose limiting when 5-FU and CF are administered weekly for 6 of 8 weeks, diarrhea occurred rarely on this combination regimen with 5-FU and CF administered only 4 of every 8 weeks. The dose-limiting toxicity of FAM-CF was cumulative myelosuppression, which also occurs with the standard FAM regimen. As a result, the administered dose intensity of 5-FU decreased as patients continued on study. Thus, a randomized comparison of FAM with FAM-CF would not determine whether CF modulation increases the efficacy of 5-FU when it is administered in optimal doses to patients with gastric cancer.

Thirty-four consecutive patients with measurable advanced gastric cancer were treated in a disease oriented Phase II study with high-dose folinic acid (HDFA) 300 mg/m2 10 min. inf., followed immediately by etoposide 120 mg/m2 50 min. inf., followed immediately by 5-fluorouracil (5-FU) 500 mg/m2 10 min. inf., given on day 1,2,3 (ELF). Courses were repeated every 22-28 days. All patients who entered this study were older than 65 years or had underlying cardiac disease. Thirty-three patients were evaluable for response and toxicity (greater than or equal to 1 course). One patient was lost to follow up. The overall response rate was 48% (16/23) including 12% (4/33) complete remissions. Eight patients had minor responses or no change and 9 had progressive disease. Five of six patients with locally advanced and non-resectable disease had an objective response (1 CR, 4 PR's). The response rate in patients with metastatic disease was 41% (11/27). After a median observation time of 6.5 months, the median survival time was 10.5 months, with a median remission (CR + PR) duration of 8 months. Toxicity was manageable and included mild to moderate myelosuppression and gastrointestinal toxicities. One episode of life-threatening (Grade IV) leukopenia, and two episodes of severe diarrhea requiring hydration were noted. No treatment related death occurred. ELF is an effective combination in advanced gastric cancer and can be safely administered to elderly patients and patients with cardiac risk.

A registry of suspected cases of cancer-associated hemolytic-uremic syndrome (C-HUS) was established in May 1984. Records of 85 patients from the registry, all with history of cancer, hematocrit less than or equal to 25%, platelet count less than 100,000, and serum creatinine greater than or equal to 1.6 mg/dL were subjected to in-depth analysis. Eighty-nine percent of patients had adenocarcinoma, including 26% with gastric cancer. Microangiopathic hemolysis was reported in 83 patients; coagulation studies were normal with rare exception. Bone marrow examination ruled out chemotherapy-induced myelosuppression in 68 of 85. Thirty-five percent of patients were without evident cancer at time of syndrome development. Mitomycin (MMC) was part of the treatment regimen in 84 patients; all but nine received a cumulative dose greater than 60 mg. Pulmonary edema, generally noncardiogenic, developed in 65% of patients, often after blood product transfusions. C-HUS has a high mortality: over 50% of patients died of or with syndrome, most within 8 weeks of syndrome development. Conventional treatment was ineffective, although ten of 21 treated with staphylococcal protein A (SPA) immunopheresis showed significant responses. Statistical analysis found only absence of obvious tumor and treatment with SPA to suggest favorable prognosis. C-HUS is distinguishable from related syndromes such as childhood HUS, thrombotic thrombocytopenic purpura (TTP), consumption coagulopathy, and microangiopathic hemolysis associated with advanced carcinoma. MMC is likely involved in the development of C-HUS; the risk of developing C-HUS after treatment with MMC is between 4% and 15%. However, possible bias in patients referred to the registry and reports of non-MMC C-HUS cases must be remembered. Recommendations include careful monitoring of renal and hematologic function in patients treated with MMC, aggressive nontransfusion in patients with suspected C-HUS, and consideration of treatment with SPA immunopheresis in patients with definite syndrome.

Fifteen patients with inoperable advanced gastric cancer were treated with UFT.etoposide.CDDP.adriamycin (FEPA). Six were males and 9 were females with an average age of 58 (range 40 to 80 years). Nine patients were in P.S. 2 and 6 in P.S. 3. FEPA regimen was performed every 4 weeks as follows: UFT 400 mg/m2 (p.o.) every day, etoposide 50 mg/m2 (i.v.), CDDP 25 mg/m2 (i.v.) and adriamycin 10 mg/m2 (i.v.) on days 1, 8, 15 and 22. Among 15 patients, 6 partial remissions and 4 minor responses were obtained. Gastrectomy was performed in 2 of 6 PR patients after FEPA chemotherapy. The overall response rate was 40.0%. As for side effects, mild myelosuppression was the most frequent (66.7%), followed by alopecia and nausea. We concluded that combination chemotherapy of FEPA is useful for inoperable advanced gastric cancer.
