"BAR" therapy is a combined therapy with BUdR (Radiosensitizer), Antimetabolites (5-FU, FT-207 etc.) and Radiation for malignant tumours. How radiation can be reduced as far as possible and how the effects of treatment can be increased as much as possible are the objectives of this study of combining radiation and BUdR therapy. The authors attempted to irradiate 3-5 days after the BUdR and antimetabolite had been infused via the superficial temporal artery, in 12 malignant oral tumours (11 squamous cell carcinomas and 1 reticulum-cell sarcoma). BUdR 50-250 mg/day, antimetabolites (5-FU) 10-250 mg/day and a total irradiation dose of 6000 rads by 6 MeV Linac X-ray or Co-60 gamma ray, 200 rads/day were given. 9 marked responses, 2 moderate responses and 1 no response (2 cases were operated on by local resection) were obtained by the authors. Side effects of treatment were observed during the course of "BAR" therapy. Stomatitis was found in all patients and it occurred on the mucosa of the tumour-affected site especially. Dermatitis of the skin of the face was noted in 6 cases, resembling irradiation dermatitis. Fever was observed in 4 cases and it always occurred after irradiation. Diarrhoea was noted in 3 cases and occurred before irradiation, 2 out of 3 were given BUdR 0.1 g and the remaining one was given BUdR 1 g, and 5-FU lg. In addition, there were: 1 loss of appetite, 1 nausea and 1 exfoliation of nails.

The effects of a group of elemental diets on the gastrointestinal toxicity of 5-FU in the Sprague-Dawley rat were evaluated. Diarrhea, stomatitis, hypoalbuminemia, and early deaths were more frequent in the animals on elemental diets than in those consuming standard rat chow. Sepsis and hypoalbuminemia were directly related to the extent of protein hydrolysis of the particular elemental diet.

In a prospectively randomized study the effect of adjuvant chemotherapy with 5-FU on survival and recurrence was analyzed in 274 evaluable patients with colorectal carcinoma who either underwent a curative or a palliative resection. In the treatment group, chemotherapy consisted of the intravenous administration of 5-FU 12 mg/kg daily for four consecutive days, then 6 mg/kg/per day on alternate days to the point of toxicity or to a maximum of 5 doses, followed by 12 mg/kg/week for one year. Drug toxicity was rarely severe and consisted of nausea and vomiting, diarrhea, stomatitis, leukopenia, and thrombocytopenia in slightly more than half of all patients. There have been no drug-related deaths. Analysis of the survival curves and disease-free interval curves reveal some evidence of drug benefit in both the curative group of resections and the palliative group of resections. However, this benefit is not significant except in those treated to toxicity. The disease-free interval after curative resection is significantly longer in patients treated with 5-FU to the point of toxicity with a white blood count less than 4,000 cells/mm3. We conclude that a preliminary analysis of the Central Oncology Group data in this trial does not make a convincing case for the use of 5-FU as an adjuvant to the surgical treatment of colorectal carcinoma.

5-Fluorouracil (5-FU) is still the mainstay of chemotherapy in patients with metastatic colorectal cancer. A prolonged infusion of 5-FU is more active than any other schedule of 5-FU used to date. Cisplatin does not improve treatment results compared with 5-FU alone and is not recommended outside clinical trials. Biomodulation of 5-FU is a major step forward in the treatment of colorectal cancer patients and as the standard chemotherapy for advanced colorectal cancer. Two schedules of folinic acid daily for 5-day (low and high doses) and weekly high dose in combination with daily or weekly 5-FU are the most widely used schedules. Although the response rates to either schedule are comparable, the profile of toxicity is different, being stomatitis for the daily schedule and diarrhea for the weekly schedule as the dose-limiting toxicity. Modulation of 5-FU by methotrexate is time dependent. An interval of 24 hours between methotrexate and 5-FU is necessary for effective modulation. Other modulators, like interferon and N-phosphonoactyl-L-aspartate (PALA), are promising treatment options currently under investigation in randomized trials. The data from phase II and III trials using modulation of 5-FU by folinic acid, PALA, or methotrexate, or using continuous infusion 5-FU indicate that all of these strategies are active. Randomized trials are currently underway to further investigate these therapeutic approaches and whether a specific modulation offers more therapeutic advantages.

In vitro studies have documented the synergistic activity of interferon (IFN) and fluorouracil (5-FU) in human cancer cell lines, and recent clinical trials have demonstrated the efficacy of this combination in metastatic colon cancer. The current study was undertaken to evaluate the combination of IFN alpha-2a plus 5-FU in previously untreated patients with metastatic renal cell carcinoma. From May 1990 through August 1990, 14 patients with metastatic renal cell carcinoma were treated with 5-FU 750 mg/m2/day continuous infusion IV days 1-5, followed by weekly IV infusions of 5-FU 750 mg/m2 beginning on day 12. Patients concurrently received IFN alpha-2a 9 x 10(6) IU subcutaneously 3 times per week beginning on day 1. The median age of patients treated was 57 (range 38-80) with a median Karnofsky performance status of 90 (range 60-100). Sites of metastases included lung only in 6 patients, liver only in 1 patient, 1 patient had bilateral disease at presentation, and the remaining patients had multiple sites of metastases. The median duration of therapy was 2 months. The predominant toxicities seen were stomatitis, nausea, flu-like symptoms and neurotoxicity. The only grade IV toxicity observed was severe vomiting in 1 patient, though 5 patients discontinued therapy within 2 months because of poor subjective response. With a minimum follow-up of 13 months no objective responses were seen. Thirteen of the 14 patients have had progressive disease and 11 have died. The median time to progression was 2 months (range 0.5-6 months) and the median survival was 5 months (range 2-14.5 + months).(ABSTRACT TRUNCATED AT 250 WORDS)

From April 89 to October 90, 41 patients operated for a Dukes B or C colorectal cancer were randomized to receive 6 courses of adjuvant treatment with (A) 5-FU alone (440 mg/m2 IV bolus 5/21 days) or (B) folinic acid (200 mg/m2 IV bolus 5/21 days) preceding 5-FU (370 mg/m2 in short infusion 5/21 days). Ten patients received also one course of immediate post-operative continuous portal infusion (5-FU 500 mg/m2/day x 7 followed by a 2 hours infusion of mitomycin C 10 mg/m2). The portal treatment was well tolerated (1 case of GI tract disturbances, 1 catheter obstruction). The toxicity of adjuvant systemic treatment was evaluated on 232 courses (125 A, 107 B). Hematologic and skin toxicities, alopecia and nausea-vomiting were mild. The limiting toxicities (expressed as percentages of courses) were stomatitis (grades 2-3: 11.4% A; 22.6% B) and diarrhea (grades 3-4: 7.3% A; 14.2% B; one toxic death was to deplore in arm B from a grade 4 diarrhea). The pilot study has demonstrated the feasibility of the adjuvant treatment proposed; a multicentric randomized trial (expected accrual: 800 patients) has therefore been activated on 11.01.90; all patients will also receive levamisole while radio-therapy will be mandatory for rectal cancer.

The benefits from medical treatment in colorectal cancer are limited. Fluorouracil remains the only recognized drug, and how to treat unresponsive patients is still debated. To evaluate the role of folinic acid (FA) in circumvence resistance in colorectal cancer, 28 patients pretreated with fluoropyrimidine were candidated to receive one of the following schedules: fluorouracil (600 mg/m2) associated with FA (500 mg/m2) weekly for 6 weeks (Regimen A: 21 cases), or fluorouracil (370 mg/m2) plus FA (200 mg/m2) daily for 5 days every 4 weeks (Regimen B: 7 cases). Fourteen patients were pretreated with doxifluridine, a new fluoropyrimidine derivative with a peculiar mechanism of action, and the remaining 14 patients with fluorouracil. All but 2 patients were unresponsive to first-line treatments. When the treatment began, the median age of the patients was 60 years (range, 30-68). The performance status (ECOG) was 0/1 in 25 of them, and the primary tumor was in the colon and rectum in 19 and 9 patients, respectively. Sites of disease were liver (64%), lung (35%), local recurrence (10%) and peritoneum (10%). A median of 3 cycles (range, 1-7) was delivered, and no objective response was observed in the group of patients pretreated with doxifluridine or in the group pretreated with fluorouracil. In 5 cases a significant decrease in baseline CEA values was observed. Therapy was well tolerated, and no grade 4 toxicity was encountered. Severe toxicity was limited and included diarrhea (7 patients), stomatitis (1 patient) and nausea/vomiting (1 patient). High-dose FA has no role in reversing resistance to fluoropyrimidine, and other mechanisms of refractoriness are surely involved. FA should be associated with fluoropyrimidine as first-line therapy together with other biochemical modulators. Further rescue therapies need to be developed.

Hepatic regional treatment represents an attempt to improve tumor response by increasing drug concentration with low systemic toxicities. Recently in vitro and clinical studies have shown that the cytotoxicity of 5-fluorodeoxyuridine (FUDR) and 5-fluorouracil (5FU) can be potentiated by high doses of leucovorin (LCV). Two pilot studies with intraarterial FUDR, 5FU, and LCV were initiated. Since 1982, 221 patients with colorectal liver metastases were treated by various forms of long-term monthly continuous regional treatment using implantable ports or pumps. FUDR (0.05 to 1.7 mg/kg/d) was administered alone or combined with 5-FU and leucovorin. In 61 patients curative liver resection was possible and was followed by adjuvant arterial treatment. Overall median survival time (MST) was 15 months and increased to 36 months after liver resection. This was influenced by the following important factors: treatment, number of metastases, extent of infiltration, tumor volume, and minimal intraoperatively diagnosed extrahepatic disease. The response rate varied from 69% to 23%. Time of development of extrahepatic progression was not delayed by additional systemic treatment. Local side effects significantly depended on the duration of arterial infusion. The rate of biliary sclerosis ranged from 19% to 0%. Occurrence of chemical hepatitis was between 7% and 38%. In contrast, after combined intraarterial treatment with LCV, systemic side effects, mainly stomatitis and diarrhea, were dose limiting. Despite the improvement of survival after regional treatment, further randomized trials are mandatory to compare regional with relevant systemic treatment.

Previous studies have demonstrated continuous-infusion 5-fluorouracil (CI 5-FU) to be an active single-agent treatment for breast cancer without significant myelotoxicity. These qualities made CI 5-FU an attractive agent for combination with other effective but myelosuppressive agents. In this study we attempted to determine the maximal doses of CI 5-FU that could be added to a combination of agents known to be dose limited by myelotoxicity, doxorubicin 50 mg/m2 day 2 and cyclophosphamide 150 mg/m2 days 3-12 of a 28-day cycle. Patients who received doxorubicin and cyclophosphamide alone developed significant myelotoxicity but did not develop stomatitis. The addition of 5-7 days of CI 5-FU at 200-300 mg/m2 was associated more closely with increased stomatitis (P = .11) than with increased granulocytopenia (P = .57). The stomatitis observed for low doses of CI 5-FU given with doxorubicin and cyclophosphamide would not have been expected for these low doses of CI 5-FU given as a single agent. We conclude that the addition of CI 5-FU to myelotoxic doses of doxorubicin and cyclophosphamide is not a promising therapeutic strategy for significantly increasing the effectiveness of this combination of agents.

60 patients with advanced carcinomas of the oropharynx and hypopharynx underwent chemotherapy, either with 5-FU/Cisplatin (n = 30) or with 5-FU/Carboplatin (n = 30). The remission-rates (complete and partial remissions) were comparable in both groups. The rate of complete remissions, however, was statistically significant higher in the cisplatinum group (6 patients) than in the carboplatinum group (1 patient). 2 patients of the 5-FU/Cis-group and 4 patients of the 5-FU/Carbo-group developed a progressive disease during chemotherapy. Statistically significant differences were found in the nephrotoxic and myelotoxic side effects between both therapy groups: nephrotoxic side effects were more frequent in the 5-FU/Cis-group, whereas myelotoxic side effects occurred mainly in the 5-FU/Carbo-group. The chemotherapy with 5-FU/Carboplatin was better tolerated by the patients than in the 5-FU/Cisplatinum-group. In the 5-FU/Carbo-group especially a lower rate and severity of loss in weight, nausea, vomiting, alopecia and mucositis/stomatitis was observed. No statistically significant differences were found in ototoxic side effects between both groups.
