Taxol, selected for clinical trial because of its animal antitumor activity and unique structure and mechanism of action, was administered in Cremophor by i.v. infusion over 6 h in a phase I study. Eastern Cooperative Oncology Group toxicity grading was used. Eighty-three taxol courses were administered to 34 patients. Grade 3-4 hypersensitivity reactions occurred in 4 of 13 courses at the first 2 dose levels, but premedication with dexamethasone, diphenhydramine, and cimetidine resulted in only 3 additional Grade 2 reactions in the next 70 courses. Neurotoxicity, which resolved or improved after stopping therapy, was Grade 1 with 2 of 10 courses of 230 mg/m2 and Grades 1-3 after 11 of 12 courses of 275 mg/m2. Leukopenia, first seen (Grade 1) after 1 of 8 75 mg/m2 courses, was Grades 3-4 after 10 of 34 courses of 175-230 mg/m2 and 10 of 12 courses of 275 mg/m2. The WBC nadir occurred at a median of 10 days and the median time required for normalization of the WBC was 18 days. Alopecia began 2-3 weeks posttaxol in 2 of 9 patients treated with 75-135 mg/m2 and in all 16 patients (Grade 3) treated with 175-275 mg/m2. Grades 1-2 nausea and vomiting occurred in about one-third of the patients treated at a dose of 105 mg/m2 or more. Taxol disappearance from plasma was biphasic; half-lives of the first and second phases after a 275 mg/m2 dose were 0.32 and 8.6 h, respectively. The apparent volume of distribution was 55 liters/m2, and the peak plasma concentration with a dose of 275 mg/m2, which occurred immediately postinfusion, was approximately 8 microM. Only 5% of parent drug was excreted in the urine within 24 h. Minor objective responses were noted in one patient with gastric cancer and another with ovarian carcinoma. In addition, one patient with massive ascites due to metastatic adenocarcinoma from an unknown primary had only minimal sonographic evidence of ascites for 6 months posttreatment. Neurotoxicity and leukopenia were dose limiting in this schedule. The recommended phase II trial dose is 250 mg/m2, with premedication.

Disease-oriented phase II trials of doxifluridine were performed in advanced colorectal, breast, renal, endometrial, stomach, and ovarian carcinomas. The dose schedule recommended by the phase I trial (12.5 g/m2 by continuous iv infusion over 6 hours once a week for 3 weeks followed by a 1-week rest) was chosen first: the initial dose was later decreased to 10 g/m2 due to the fact that several neurotoxic effects were reported. A total of 207 patients were entered: 137 patients who received at least two courses of treatment were evaluable for response. Therapeutic activity was demonstrated in breast cancer [two complete responses (CR) and 13 partial responses (PR) among 42 patients], colon cancer (seven PRs among 35 patients), and rectal cancer (six PRs among 23 patients). Some therapeutic activity was detected in ovarian cancer (one CR among nine patients), endometrial cancer (one PR among five patients), and stomach cancer (one PR among five patients). No significant activity was noticed in renal cancer (one PR among 18 patients). Nonhematological toxicity was evaluated according to World Health Organization criteria. Nausea and vomiting were recorded in 50% of the patients (Grade 3-4 in 5%), diarrhea was recorded in 20% (Grade 3-4 in 5%), and cutaneous and allergic reactions were recorded in 10% (Grade 3-4 in 2%). Myelotoxicity during the first treatment course was mild; median wbc and platelet count nadirs (x 10(9) cells/L) were 4.1 (range, 0.1-11) and 194 (range, 20-482), respectively. Nevertheless, some cases of acute leukopenia and thrombopenia were reported. Consciousness alterations and neurologic symptoms were the major side effects (72 of 173 evaluable patients), since treatment had to be interrupted in 34 patients and four lethal neurotoxic effects occurred. At the same total dose of doxifluridine, the risk of neurotoxicity significantly increases with age and with the weekly dose and to the contrary it decreases with increasing bilirubin level. Although activity was demonstrated, this treatment cannot be recommended because of major neurotoxicity. Further pharmacological studies seem warranted to define the optimal dosage schedule and to obtain a better therapeutic index.

Twenty-five patients with gastrointestinal tumors (stomach 13, colon 8, pancreas 2, liver 2) were treated with a combination chemotherapy regimen consisting of CDDP (30 mg/m2/day d 1, 2) and 5-FU (500 mg/m2/day d 1-3), repeated every 3 or 4 weeks. The patients comprised 14 males and 11 females with a median age of 50 years (range 24-69), and a median performance status of 80% (range 40-100%). Thirteen patients had had prior chemotherapy. Partial response was observed in 2 patients (colon and liver), which lasted for 2 months each, respectively. No objective response was observed in 11 patients evaluable for gastric cancer. Non-hematological toxicities were nausea (92%), vomiting (56%), proteinuria (17%), transient elevation of BUN (8%), and hepatotoxicity (11%). Leukopenia and thrombocytopenia were observed in 71% and 25%, respectively. However, these toxicities were mild to moderate, and generally well tolerated.

The effect of postoperative immunochemotherapy with mitomycin C (MMC), 5-fluorouracil (5-FU) and OK-432 was evaluated as an adjuvant therapy after curative resection for gastric cancer. Immediately after surgery, patients were randomly allocated to the following three treatments: (A) chemotherapy with MMC and 5-FU (32 cases); (B) chemoimmunotherapy with MMC, 5-FU and OK-432 (33 cases); and (C) surgery alone as control (34 cases). There were no significant differences in the background factors influencing survival time among the groups, and there was no dose-distribution of chemotherapeutic agents between groups A and B. While the differences were not statistically significant, the survival rate and disease-free interval of group B were better than those of groups A or C. Side effects such as gastroenteric disorder, leukopenia (less than 3,000/mm3), thrombocytopenia (less than 7 X 10(4)/mm3) and increase of serum transaminase level (GPT greater than or equal to 100 units) were less frequently observed in group B than in group A. The results of the present study seemed to indicate that chemoimmunotherapy with OK-432 may be effective for surgical adjuvant therapy.

To evaluate the therapeutic effects of THP-adriamycin (THP), single agent chemotherapy and combination chemotherapy with THP were undertaken in 16 patients with advanced gastric cancer. In the eight patients in the THP single agent group. Only three minor responses (MRs) were obtained. However, three partial remissions (PRs) and one MR were observed in the eight patients in the THP combination group. In which 5-FU was two patient FT-207 in another two and CDDP in one. No severe side effects were observed with the THP chemotherapy, while leukopenia of less than 3,000/mm was commonly seen (69%). Only three patients showed alopecia. Thrombocytopenia of less than 30,000/mm3 and transient arrhythmia were observed in one patient each. These side effects were apparently milder than those with adriamycin. From a pharmacokinetic study of THP and adriamycin. It was found that THP was superior to adriamycin in its transferability from the blood to cancer tissue. In conclusion, it is suggested that combination chemotherapy with THP is useful for advanced gastric cancer.

Seventeen patients with advanced gastrointestinal cancer were treated with a combined chemotherapy of UFT with Adriamycin (UFT-A). The UFT-A regimen consisted of UFT, 600 mg/body daily. As for the Adriamycin, 10 mg/body was give intravenously from day 1-4 and was repeated every two weeks. Partial responses were seen in 7 cases (41%) (5 cases of gastric cancer, 1 case of colon cancer, and 1 case of bile-duct cancer) out of 17 evaluable patients (7 cases of gastric cancer, 3 cases of colon cancer, 4 cases of biliary tract cancer, and 3 cases of pancreatic cancer). Two patients had minor responses, and in eight patients their disease had stabilized. As for side effects, nausea and vomiting occurred in seven patients (41%), and anorexia was observed in eight patients (47%). Two patients (12%) showed a leukopenia count of less than 2,000/mm3 and none of these seventeen patients had thrombocytopenia, of less than 5 x 10(4)/mm3. Considering these results, UFT-A therapy appears to be useful in cases of advanced gastrointestinal cancer, especially gastric cancer.

Twenty patients with advanced gastric cancer were treated with FAP.MMC (5-FU 350 mg/m2 i.v. on days 1-3, ADM 40 mg/m2 i.v. on day 1, CDDP 20 mg/m2 i.v. on days 1-3, MMC 6 mg/m2 i.v. on day 1), administering 5-FU, ADM and CDDP every 4 weeks and MMC every 8 weeks. Fourteen patients were evaluable for responses. Four (29%) partial responses and two minor responses were observed. The median duration of partial response was 3.8 months (range 2.5-7 months). The median overall survival time was 5 months (range 1.5-15 months). Leukopenia was relatively severe, with a median WBC nadir of 1,300/mm3. Nausea and vomiting were frequent but moderate. However, these toxicities were clinically manageable. FAP.MMC was thus considered effective for advanced gastric cancer.

A phase II clinical trial of epirubicin, a new anthracycline anticancer antibiotic, was carried out in 41 patients with inoperable or recurrent gastric cancer. Epirubicin was administered by i.v. injection; the dosages were either 40-60 mg/m2 every three weeks (Regimen A) or 20-30 mg/m2/day for 3 days every three weeks (Regimen B). Twenty-one patients were entered into Regimen A, and 20 into Regimen B. Of 31 evaluable patients, 16% (5/31) experienced objective response (PR); i.e., 20% (three of 15) treated with Regimen A and 13% (two of 16) with Regimen B, showing that there was no significant difference in the rate of response between the two regimens. Adverse effects observed were relatively mild in most cases and included anemia, leukopenia, thrombocytopenia, anorexia, nausea/vomiting, diarrhea, stomatitis and alopecia. Tachycardia and extrasystole were observed in 3 cases but disappeared upon discontinuation of the treatment. In conclusion, epirubicin seemed to have therapeutic activity comparable to that of doxorubicin in gastric cancer while being less toxic than doxorubicin, and is expected to become a better alternative to the latter drug.

A phase II study of epirubicin, a new anthracycline derivative, was performed in 23 patients with advanced gastric cancer. Epirubicin was administered intravenously at a dose of 20-30 mg/m2/day for two or three consecutive days every two or three weeks. Sixteen cases were evaluable and there were two partial responses and one minor response. Overall response rate (more than PR) was 12.5% (2/16). Leukopenia (less than 4,000/mm3) and anemia (less than 11.0 g/dl) were observed in 71.4% and 69.2% of patients, respectively. No thrombocytopenia was observed. Other toxicities were alopecia (71.4%), nausea and vomiting (42.9%), anorexia (25.0%), stomatitis (12.5%), fatigue (12.5%), fever (6.3%) and tachycardia (6.3%), but these effects were relatively mild in most cases.

Eighteen patients with advanced metastatic gastrointestinal cancer (stomach cancer 7, liver cancer 9, pancreas cancer 2) were treated with human recombinant interferon alpha-2 at doses of 3.0 X 10(6)-10.0 X 10(6) IU/body i.m. daily or every second day, 30 X 10(6) IU/body for five consecutive days every four weeks, or 30 X 10(6) IU/body once weekly. No tumor response was demonstrated in any of our cases. Among fifteen evaluable cases, nine had stabilization of evaluable disease at four weeks, but six showed progressive disease. On the other hand, fever, chills, fatigue, anorexia, nausea and vomiting were pronounced. In two cases, CNS toxicities developed. In some instances, leukopenia, thrombocytopenia, decrease of hemoglobin content and elevation of transaminase were observed. According to these findings, single use of recombinant interferon alpha-2 at the dose schedule outlined above does not seem to be of use for the treatment of advanced gastrointestinal cancer.
