5 FU infusion with mitomycin-C vs. 5 FU infusion with methyl-CCNU in the treatment of advanced upper gastrointestinal cancer: a Southwest Oncology Group Study.

A randomized trial was conducted by the Southwest Oncology Group (SWOG) in advanced carcinoma of the stomach and pancreas. Patients were assigned to receive monthly 5-fluorouracil 96-hour continuous infusions with either bolus mitomycin-C or oral methyl-CCNU. Mitomycin-C and methyl-CCNU were administered every eight weeks. The 5 FU-mitomycin combination produced a 14% and 22% response rate in disseminated stomach and pancreatic carcinoma, respectively. The combination of infusion 5 FU and methyl-CCNU achieved responses in 9% and 5% of stomach and pancreatic tumors, respectively. There was no significant difference in survival between limbs for either tumor. Median survival in gastric carcinoma on the 5 FU-mitomycin regimen was 25 weeks vs. 18 weeks on the 5 FU-METHYL-CCNU arm. In pancreatic carcinoma median survival on the mitomycin limb was 19 weeks as compared to 17 weeks on the methyl-CCNU program. Leukopenia was greater for the first course on the mitomycin limb. Regression analysis demonstrated that performance status was the most important pretreatment characteristic for predicting survival in both tumors. Neither 5 FU infusion combination appears to significantly alter the dismal prognosis of advanced upper gastrointestinal neoplasms.

[Primary gastric plasmacytoma with IgG dysgammaglobulinemia and macrocytic anemia (author's transl)].

The authors report a case of a woman aged 76 years with a single plasmocytoma of the stomach secreting large quantities of a paraprotein of the IgG type with Kappa light chains. A macrocytic anemia due to deficiency of gastric intrinsic factor was also present. This pathological association is extremely rare. About sixty cases of gastric plasmocytoma are been reported in the published literature and their principal characteristics are briefly outlined.

Pancreatic cancer treated with carmustine, fluorouracil, and spironolactone: a randomized study.

A prospective randomized trial between two drug regimens in 38 patients with advanced pancreatic carcinoma was performed. The two-drug regimen consisted of carmustine and fluorouracil. The survival rate and response to these two drugs was compared to a three-drug regimen consisting of these same two drugs plus spironolactone. Objective partial responses were rare in both groups, being 3/18 in the two-drug group and 2/20 in the three-drug group. Life table analysis in previously untreated patients from time of treatment shows longer survival for the three-drug group, but this difference was not statistically significant.

[Hemodynamic aspect of post ECC cardiac failures. Study of 193 cases].

The aim of this study is to define the hemodynamic characteristics of this "clinical model" of acute cardiac failure observed after cardiac surgery carried out under extra-corporeal circulation, which constitutes the essential cause of "post-operative low cardiac output syndrome". The 193 patients in this study make up a representative sample of patients operated, treated and studied according to a homogeneous methodology for a period of 1 year. The clinical analysis of the post-operative circulatory condition, after exclusion of non cardiogenic syndromes, led to grouping the cases into 5 classes of circulatory change of increasing severity, each corresponding to a specific "therapeutic necessity". The hemodynamic results (intra-vascular pressures, oxymetry, cardiac output by "Cardio-Green" dilution method) are given for each of the five classes, thus defining the "hemodynamic profile" and the statistical reliability of the main objective parameters. This gives proof of the therapeutic indications for the main therapeutic procedures actually known, for which we prevent the hemodynamic effects noted for each of them. Thus, three "degrees of cardiac failure" are found: less severe (classes I and II) call for simple metabolic equilibration and possibly diuretics: the systolic work is above 160 gm/m2. Decompensated circulatory failure (classes III and IV) corresponds to a more important reduction in systolic work (9) 15 gm/m2, i.e. between 20 et 40 p. 100 of the basal value), and call for sympatho-mimetic cardiotonic agents: isoprenaline and/or dopamine. Below this value, in spite of medical treatment, the hemodynamic situation can still be sometimes reversible under circulatory assistance (diastolic counter pressure by means of an aortic balloon). Confronted with the clinical picture, the hemodynamic study enables the quantification of the circulatory change, and specification of the cardiogenic part and thus especially helps the carrying out of the treatment.
