PURPOSE:This randomized, 2 x 2 factorial study compared a semimonthly (LVFU2) with a monthly (FULV) regimen of fluorouracil and leucovorin and 24 versus 36 weeks of each regimen as adjuvant treatment of patients with stage II (Dukes' B2) and III (Dukes' C) colon cancer.PATIENTS AND METHODS:LVFU2 was administered semi-monthly for 2 consecutive days as dl- or l-leucovorin (200 or 100 mg/m2, respectively) as a 2-hour infusion, followed by a 400 mg/m2 FU bolus and 600 mg/m2 of FU as a 22-hour continuous infusion. FULV was administered monthly for 5 consecutive days as a 15-minute infusion of dl- or l-leucovorin, followed by 400 mg/m2 of FU as a 15-minute infusion.RESULTS:A total of 905 patients were randomly assigned. The median follow-up was 41 months. Disease-free survival was similar between the LVFU2 and FULV groups (127 v 124 events; hazard ratio [HR] = 1.04; P =.74) and between 24 and 36 weeks of therapy (128 v 123 events; HR = 0.94; P =.63). Analysis of overall survival showed a slight excess in the number of deaths in LVFU2 compared with FULV (73 v 59), but this difference was not statistically significant (HR = 1.26; 95% confidence interval, 0.90 to 1.78; P =.18). The most commonly observed grade 3 to 4 toxicities were neutropenia, diarrhea, and mucositis. Toxicities were significantly lower in the LVFU2 group (all toxicities, P <.001).CONCLUSION:Our data confirm that LVFU2 is less toxic than FULV. At a median follow-up of 41 months, no statistically significant difference could be detected in disease-free or overall survival between the treatment groups or treatment durations.
The aim of this randomized open-label study was to compare a bimonthly with a monthly regimen of 5-fluorouracil (5-FU) and leucovorin for the adjuvant treatment of colon and high-rectum adenocarcinoma. The bimonthly regimen was administered for 2 consecutive days every 14 days as d,L-leucovorin 200 mg/m2 or L-leucovorin 100 mg/m2 as a 2-hour infusion followed by 5-FU bolus of 400 mg/m2 and a 600 mg/m2 5-FU 22-hour continuous infusion (LVSFU2). In the monthly regimen, d,L-leucovorin 200 mg/m2 or L-leucovorin 100 mg/m2 15-minute infusion followed by a 400 mg/m2 15 minute 5-FU bolus was administered for 5 consecutive days every 28 days (FUFOL). Nine hundred five patients with recently resected stage B2 or C colon or high-rectum adenocarcinoma (inferior pole of the tumor subperitoneal) were recruited into the study. Patients were randomized in a 2 x 2 factorial design to receive either LV5FU2 or FUFOL for 24 or 36 weeks. Characteristics of the patients in the two different treatment groups were similar at baseline. Compliance was good. Mean 5-FU dose intensities were 930 mg/ m2/wk and 463 mg/m2/wk for LVSFU2 and FUFOL, respectively. The incidence of maximal grade III-IV toxicities for LVSFU2 and FUFOL was neutropenia 6% and 16% (P < .001), diarrhea 4% and 10% (P < .001), and mucositis 2% and 7% (P < .001), respectively. Maximum grade III-IV toxicities in the LV5FU2 treatment group were significantly lower than in the FUFOL group (10% v 26%; P < .001). Although patients in the LV5FU2 group received twice the dose of 5-FU compared with those in the FUFOL group, LV5FU2 was shown to be less toxic. Efficacy data will be available in 2001.
BACKGROUNDSecondary meningeal localizations are uncommon and may disclose reactivation of a malignant disease. Most meningeal metastases occur in breast cancer, exceptionally in primary ovarian cancer.CASE REPORTWe report 2 cases of secondary meningeal localizations of ovarian cancer. The diagnosis was clinical, supported by cerebrospinal fluid analysis and computed tomography and magnetic resonance imaging.DISCUSSIONEstablishing the diagnosis of carcinomatous meningitis may be difficult. Clinical signs and biological data are not always conclusive. If spinal tap is contraindicated or negative, imaging, particularly magnetic resonance imaging is highly contributive in establishing the diagnosis of secondary localization. A precise evaluation of the invaded tissues is quite helpful in guiding therapeutic management based on chemotherapy, tumor resection or radiotherapy.
We report the case of a 67-year-old man who developed pericarditis as the initial manifestation of myelomonocytic leukemia. Leukemic pneumonitis developed 4 months later and the patient later died.
We describe a case of a primary nonseminomatous germ cell prostatic tumor and discuss the problem of extragonadal germ cell tumors. Prognosis, staging and management of these tumors are similar to that of metastatic primary testicular germ cell tumors.
A patient with long-standing Waldenström's disease and cryoglobulinemia, treated with chlorambucil, developed hepatocellular carcinoma. Although HBs antigen, anti-HBs, and anti-HBc antibodies were not detected in his serum by conventional polyclonal radioimmunoassays, immunofluorescence techniques showed HBs antigen to be present in hepatocytes.
This technique of anti-cancer treatment of hepatic cancers has a twofold interest: it delivers local chemotherapy in direct contact with the tumours and it allows repeated access to the blood supply of the liver without the need for surgery. This second point is particularly emphasized in the form of a technical description of the method of approach to the hepatic arterial system, which is as non-aggressive as possible and which allows permanent vascular access. This study, which required close collaboration between the departments of Vascular Radiology, Radiotherapy and Surgery, was initially considered as a feasibility study of a technique enabling the simple use of implantable vascular access sites.
