Endoscopic Diagnosis of Early Malignant Lymphoma of the Stomach

Abstract: The findings and results obtained by endoscopies and direct vision biopsies carried out in 13 patients with early primary gastric lymphoma, were compared with those of 8 patients with RLH, 28 with depressed type of early gastric carcinoma, and 10 patients with benign gastric ulcers, to deal with problems inherent to endoscopic diagnosis of early primary gastric lymphoma The first endoscopy attained a correct diagnosis in only 1 patient (7.7%) but in 7 patients (53.8%) with the final endoscopy. Endoscopic features of early gastric lymphoma characteristically yielded a cobblestone appearance and reticulated erosion when they were compared with that of RLH, early carcinoma and benign ulcer. Furthermore, early gastric lymphoma presented ill demarcated margins associated with discoloration of the mucosa more frequently comparing with that of early gastric carcinoma. Also, hemorrhage, lustrous nodules, regulalr and white-coated ulcer were the findings more frequently seen in early gastric lymphoma but redness was less frequent in early gastric carcinoma. Dye endoscopies provided a more detailed appearance of the lesion and margins than conventional endoscopies. In addition, dye endoscopies made visible the lesions that were not visible by conventional endoscopies, in areas repelling dye solution. In this paper, the importance to pay an attention to the endoscopic findings described above and an application of dye endoscopy was emphasized for detection of an early gastric lymphoma.     

Serum Complement Levels in Uterine Cervical Cancer Patients and Their Relationship to Cell-Mediated Immunity

C3 and C4 concentrations in the serum of uterine cervical cancerpatients and healthy controls were determined and their relationshipto other immunological parameters was studied. Complement levelsin cancer patients were significantly higher than those in thehealthy controls. However, complement levels in cancer patientsin Stage IV were almost the same as those in the controls. Therewas a significant correlation between complement levels andlymphotoxin activity of the lymphocytes. Although lymphocyteresponse to phytohemagglutinin was depressed, elevated complementlevels were maintained in cancer patients in Stages I, II andIII.     

A Preliminary Report on Autologous Bone Marrow Transplantation for the Treatment of Advanced Non-Hodgkin's Lymphoma

Four patients with advanced non-Hodgkin's lymphoma of unfavorablehistology were treated with marrow-lethal doses of cyclophosphamide(CY) and total body irradiation (TB1) followed by the infusionof cryopreserved autologous marrow. All four patients showedengraftment after autologous bone marrow transplantation andachieved complete remission (CR). Three of them, however, developedrelapse in 1.7, 12.9 and 14.5 mo respectively after the transplantation.The other patient has survived in drug-free CR for more than16.6 mo. There was no treatment-related death although therewere some tolerable complications. These data suggest that theCY-TBI regimen may be effective in inducing CR in patients withadvanced non-Hodgkin's disease but it does not contribute topreventing relapse.
