A 63-year-old female, who had undergone sigmoidectomy for sigmoid carcinoma one year before, was admitted for multiple liver metastases. A urokinase-immobilized catheter was introduced into the proper hepatic artery via the gastroepiploic artery operatively. A daily arterial infusion of 5-FU (250 mg) was combined with a weekly arterial infusion of adriamycin (30 mg) or MMC (10 mg). After discharge, 5-FU (200 mg/day) was given orally and MMC (10 mg) was infused intraarterially every other week at an outpatient clinic. ADR or MMC was infused with angiotensin II, known to increase arterial blood supply to a malignant lesion. Ultrasonography demonstrated 35 to 50% reduction in tumor diameter. The density of metastases seen in computerized tomography became low indicating tumor necrosis. Plasma CEA level, which had initially been as high as 864 ng/ml, decreased rapidly and has remained within normal limits up to the present time. Arterial infusion chemotherapy using 5-FU, ADR or MMC in combination with angiotensin II seems to be effective in the treatment of multiple hepatic metastases from colorectal carcinoma.

Because of the poor local control rates obtained with external beam irradiation +/- chemotherapy for locally advanced pancreatic cancer, our institution has used intraoperative radiation therapy (IORT) with electrons to deliver a single "boost" dose of radiation in 52 patients with biopsy-proven adenocarcinoma (primary, unresectable-49; primary, residual-2; and recurrent, unresectable-1). Patients received 4500-5000 rad of fractionated external beam irradiation and an IORT dose of 1750 rad (2 patients) or 2000 rad (50 patients). Acute and chronic tolerance have been acceptable. Documented local progression within either the external beam or IORT fields has been infrequent (3 of 42 evaluable patients or 7%), but there has been little, if any, change in median or long-term survival from that seen in external beam series. This is probably because of a high incidence of liver and peritoneal metastases with pancreatic cancer. A phase II pilot trial, which combines upper or total abdominal irradiation and infusion 5-FU with tumor nodal irradiation plus IORT, is in progress in our institution to evaluate tolerance and the relative incidence of abdominal failures.

A 57-year-old female patient with recurrent sigmoid colon cancer was successfully treated with 5-FU and UFT for 8 years. The patient, with cancer recurrence in the para-aortic lymph nodes, which were palpated in the abdomen, was given oral 5-FU at a daily dose of 200 mg. During the second week of administration, the mass showed a remarkable decrease in size, and complete disappearance was achieved within one month. However, 5 years and 2 months after discontinuation of 5-FU administration, recurrence in the supra-clavicular lymph nodes and para-aortic lymph nodes was recognized. After administration of UFT at a daily dose of 600 mg, complete disappearance of para-aortic lymph node recurrence was observed. At present, the patient is under observation as an outpatient at our hospital. This case suggests the effectiveness of 5-FU and UFT for lymph node metastases of sigmoid colon cancer.

If liver metastases are diffuse and spread out in the two lobes of the liver, the question remains as to which treatment should be given. Experimental studies showed that when a tumor grows, its vascular pattern becomes mainly arterial. However, if the tumor is still increasing, its center becomes progressively necrotic. After hepatic artery ligation the blood flow of the liver metastases decreases by 90% in the tumor but depriving the arterial circulation of the tumor is not sufficient to achieve a complete cure since the portal blood supply always saves a rim of neoplastic cells around the necrotic area. On the other hand, local infusion of chemotherapy for liver metastases by the arterial route showed a response rate varying between 34 and 70% and the median survival varying between 8 and 17 months. When FUdR chemotherapy was administered using a totally implantable drug infusion pump no improvement in the survival was observed and moreover a high level of toxicity was described including hepatitis and biliary sclerosis. A combined therapy seems a rational approach to treat tumor cells in surviving to the arterial ligation by perfusing the liver with cytotoxic drugs via the portal vein. Taylor's study was very promising but a randomized phase III clinical trial led by the gastrointestinal cancer group of the EORTC with the aim to evaluate the effectiveness of hepatic artery ligation and portal infusion of 5-FU did not show any difference in the survival of the treated patients when compared with patients treated by hepatic artery ligation alone. 77 patients were registered. Data are now available for 55 patients, respectively 30 and 25 patients in the treated group and in the control group. In both groups the median time to progression was 6 months and the median survival time was 12 months. 20% of the patients treated by hepatic artery ligation and portal chemotherapy had a response, one of them with a complete response, 5 with partial response and 14 patients without significant change in the size of their metastases. On the contrary, in the group treated by hepatic artery ligation alone, only one patient had a partial response with 13 patients having no change in the size of their metastases.(ABSTRACT TRUNCATED AT 400 WORDS)

Advanced gynecologic neoplasms continue to pose major therapeutic problems; 22,500 deaths were estimated for 1987. Between December 1983 and October 1985, there were 25 patients evaluated at our institution who on joint evaluation by the radiation oncologist and gynecologic oncologists were found to have extensive disease not amenable to standard therapy. Patients were to be treated by a combined modality approach with Mitomycin-C and 5-Fluorouracil given concomitantly with radiotherapy. Nineteen patients were treated definitively and six patients were treated with palliative intent (24 primary, 1 recurrent). The patients ranged in age from 27 to 90 years with a mean of 57.3 and a median of 57. Primary sites at presentation were: cervix--14 patients, vagina--7 patients, and vulva--4 patients. The initial FIGO stages at time of the initial diagnosis were: Stage I--1 (recurrent), Stage II--4, Stage III--15, and Stage IV--5. Chemotherapy consisted of 5-fluorouracil 1 gm/m2 given continuous infusion for 4 days with Mitomycin-C 10 mg/m2 IV push on day 1. Radiation therapy was started on day 1. Only 2 of 25 patients (8%) required chemotherapy reductions. All 25 patients received mega-voltage irradiation. The external beam dose range was 2000-6500 cGy and 14/25 patients received intracavitary or interstitial therapy. In the definitive patient group, there was no reduction in the therapeutic dose. Only four patients underwent surgical therapy. With a minimum follow-up of 8 months and a median follow-up of 28 months, the survival for the entire population was 56%. Fourteen of the 19 patients (74%) treated definitively are surviving with 12 patients having no evidence of disease. Survival by site in the definitive therapy group was cervix--70%, vulva--100%, and vagina--66%. The overall response rate was 84% at 3 and 9 months (3 months; CR--36%, PR--48%, and 9 months; CR--60%, PR--24%). There were no local recurrences in the 12 patients who achieved a complete response. Three patients died of metastatic disease alone and the overall local control was 60%. Evaluation of therapeutic side effects was performed. Hematologic analysis by the Southeastern Oncology Group criteria showed neutropenia in 14 patients (1--life-threatening, 2--severe, and 11 patients--mild/moderate) and thrombocytopenia was observed in 11 patients (all mild or moderate). All hematologic complications resolved. Acute complications did not appear increased except for the addition of mild oral mucositis (12 patients). Six patients demonstrated late effects with only 2 patients felt to have severe complications.(ABSTRACT TRUNCATED AT 400 WORDS)

The authors present a retrospective study concerning 135 cases of untreated synchronous metastases from colorectal cancer. The median survival is 5.5 months and the natural history is depending on the percentage of liver replacement, on the "performance status" of each patient and on the stage of primary tumors classified according to Dukes. The seric levels of Alkaline Phosphatase and CEA are other useful prognostic factors. The age of patients and systemic chemotherapy (5-Fluorouracil) are not able to influence the evolution of the disease. At last different techniques, both curative and palliative, used in the current treatment of liver metastases from colorectal cancer are discussed and the reported survival improvements reaching with these forms of treatment are compared to the natural history of the disease.

We added high-dose oral leucovorin to the combination of cisplatin and fluorouracil (5-FU) to assess the efficacy of this regimen in the treatment of patients with head and neck cancer. Cisplatin, 100 mg/m2, was followed by a 5-FU continuous infusion at 600 mg/m2/d for five days. Leucovorin, 50 mg/m2, was administered at the start of cisplatin and every six hours throughout the duration of the 5-FU infusion. The dose of 5-FU was escalated to 800 mg/m2 and 1,000 mg/m2 according to observed toxicity. In a second phase of the study, the dose of leucovorin was escalated to 50 mg/m2 every four hours. A total of 25 patients were registered: 23 had recurrent disease after extensive prior treatment; and two had newly diagnosed metastatic disease. The maximally tolerated dose of 5-FU was 800 mg/m2/d with leucovorin administered every six hours. Toxicities at that level included mild to moderate myelosuppression and dose-limiting mucositis in the previously irradiated field. Identical toxicities were observed when administering 800 mg/m2/d of 5-FU with leucovorin every four hours. Eighteen patients were evaluated for response: one had a pathologic complete response; nine had a partial response (including four who received prior cisplatin and 5-FU as induction chemotherapy); and eight patients failed to respond. The mean peak and trough plasma leucovorin concentrations were 2.61 (+/- 1.07) mumol/L and 2.46 (+/- 0.95) mumol/L with administration of the drug every six hours, and 2.75 (+/- 2.15) mumol/L and 2.52 (+/- 1.48) mumol/L with administration every four hours. We conclude that the combination of cisplatin, 5-FU, and leucovorin has activity in the treatment of recurrent head and neck cancer. The maximally tolerated dose of 5-FU in this study was 800 mg/m2/d, with mucositis in previously irradiated sites being dose-limiting. Plasma leucovorin concentrations exceeding 1 mumol/L are achieved following oral administration of this drug.

From May 1984 through December 1986, 141 patients with metastatic adenocarcinoma of the colon or rectum were entered on this Hoosier Oncology Group (HOG) trial evaluating the role of cisplatin in systemic therapy. Patients were stratified by the presence or absence of hepatic metastases and by performance status, and were subsequently randomized to receive fluorouracil (5-FU) (15 mg/kg/wk) alone or the same dose of 5-FU plus cisplatin (60 mg/m2 every 3 weeks). The total duration of treatment was six cycles (18 weeks). In 132 fully evaluable patients the objective response rates were 19% for 5-FU and 22% for 5-FU plus cisplatin. Statistically, the median survival times of 40 and 39 weeks were not significantly different (P = .62). However, the median duration of remission (MDR) was superior (P = .05) for 5-FU alone. This study fails to confirm clinically significant synergy of 5-FU plus cisplatin in the treatment of metastatic colorectal cancer.

Risk factors for isolated local-regional (LR) recurrence following mastectomy for breast cancer were analyzed in a review of 627 women entered into Eastern Cooperative Oncology Group (ECOG) adjuvant chemotherapy trials between 1978 and 1982. Premenopausal patients were randomized to cyclophosphamide, methotrexate, and fluorouracil (5-FU) (CMF), cyclophosphamide, methotrexate, 5-FU, and prednisone (CMFP), or cyclophosphamide, methotrexate, 5-FU, prednisone, and tamoxifen (CMFPT). Postmenopausal patients were randomized to observation, CMFP, or CMFPT. Median follow-up time was 4.5 years. At 3 years, 225 patients relapsed and in 70 (31% of failures, 11% of all patients) the initial site was LR without distant metastases. In a multivariate analysis, the risk of an isolated LR recurrence significantly correlated with the number of positive axillary nodes, the primary tumor size, the presence of tumor necrosis, and the number of axillary nodes examined. Factors that significantly discriminated between an isolated LR recurrence and distant metastasis were the number of positive nodes and primary tumor size. Patients with four to seven positive nodes or tumor size greater than or equal to 5 cm had a chance of developing an isolated LR recurrence almost equal to the risk of distant metastases. These findings suggest a potential for improved survival in this subset of patients with the addition of postmastectomy radiation to chemotherapy, and continue to emphasize the presence of a group of patients at high risk for isolated LR recurrence despite adjuvant chemotherapy.

The purposes of this administration were to inactivate cancer cells liberated from the primary tumor, to prevent them from metastasizing to other organs and to treat established metastatic cancer. Sixty-one patients with advanced gastric cancer who had received preoperative 5-FU dry syrup administration and who had also undergone curative resection between 1976 and 1982, in addition to postoperative chemotherapy (more than 20 mg MMC, 5,000 mg 5-FU), (Group A) were admitted to the present study. Their survival rate was compared with that of 67 patients given curative resection for advanced cancer without preoperative 5-FU dry syrup, who received the same postoperative chemotherapy only (Group B) during the same period. The 5-year survival rate for Group A was 0.55 +/- 0.06, higher than the rate of 0.42 +/- 0.06 for Group B. Comparing the 5-year survival rates of both groups in terms of clinicopathological factors such as stage of cancer progression, serosal invasion, lymph node metastasis, and lymphangitic and blood vessel invasion, the 5-year survival rates for Group A were higher than those for Group B. There were significant differences for histological stage III and blood vessel invasion between the two groups. From these results, it is suggested that preoperative oral 5-FU dry syrup might be effective as an adjuvant therapy to surgery for gastric cancer.
