Gaucher's disease (GD) which is a congenital defect characterized by the accumulation of glucocerebroside in cells of the reticulo endothelial system, is associated with malignancies of the lymphoid system such as multiple myeloma, chronic lymphatic leukemia, as well as acute leukemia of childhood. We report the immunological profile of the T-cell system in GD patients and in GD carriers. We found a variable response to lectins stimulation (PHA, Con A, PWM in various concentrations) which supports the hypothesis that a persistent antigenic stimulation in GD affects all components of the immune system of those patients. A highly significant decrease in the number of NK cells was also found, which might be a predisposing factor to the increase in malignant B and other lymphoid cell proliferations described in patients with GD.

Cefbuperazone (CBPZ) was administered to patients with severe infections complicating hematologic diseases to assess its efficacy and safety under such clinical conditions. Primary diseases in this series of 78 cases included; acute leukemia in 41 cases, chronic leukemia in 6 cases, other leukemia in 9 cases, malignant lymphoma in 13 cases, multiple myeloma in 3 cases, aplastic anemia in 5 cases and 1 other case. Types of infection included sepsis; proven or suspected, in 59 cases, pulmonary infection in 8 cases, upper respiratory infection in 5 cases, and other cases. CBPZ was infused by an intravenous drip method at a dosage of 4-8 g daily. Patients' ages ranged from 14 to 85 years. Clinical response to the CBPZ regimen was excellent in 24 cases, good in 22 cases, fair in 2 cases, and poor in 30 cases. Thus the overall efficacy rate (percentage of cases showing an excellent or good response) was 59.0%. Efficacy rates for individual types of infection were: documented sepsis 16.7%, suspected sepsis 58.5%, lower respiratory infection 62.5%, and upper respiratory infection 100%. CBPZ also proved to be effective in 61.0% of cases with a neutrophil count of less than 500/mm3 prior to therapy. Side effects encountered were diarrhea in 1 case, gastric discomfort in 1 case and hepatic dysfunction in 5 cases. These side effects, however, were not dose-related, and none were serious. These results indicate that CBPZ has a high therapeutic efficacy even in patient with compromised immunodefenses.

The goal of this review is to provide a readable and exhaustive reference in three major areas of geriatric oncology: complications of chemotherapy and radiotherapy, responsiveness of cancer to systemic treatment, social issues in the care of elderly patients with terminal illnesses. The conclusions of this study are: 1. Progressive deterioration of renal function is the most consistent change of aging. Adjustment of doses of renally excreted drugs to individual creatinine clearance may prevent life-threatening myelotoxicity in the elderly. 2. Intensive chemotherapy regimens (acute leukemia, non Hodgkin's lymphoma) cause more serious and prolonged myelotoxicity in the elderly. Elderly are more susceptible than younger patients to cardiotoxicity and central and peripheral neurotoxicity. Age is a poor predictor of complications in other organs or systems. 3. The prognosis of patients with Hodgkin's disease worsens with aging, possibly due to increased prevalence of mixed cellularity histology. It is controversial whether the prognosis of other neoplasias is poorer. Prognosis is not age-related in multiple myeloma. In general, elderly in good performance status may benefit from systemic cancer treatment to the same extent as younger patients, except for Hodgkin's disease. 4. The Informal Support Network, epitomized by the family, appears the most suitable environment to care for the elderly with cancer.

Circulating immune complexes were identified in 143 patients with malignant tumors (70--solid cancer, 37--acute leukemia, 21--chronic lympholeukemia and 15--myelomatosis) as well as in 64 patients with chronic inflammatory diseases. Immune complexes were detected in 40% with the aid of precipitation with polyethylene glycol alone and in 50%--by using it in combination with an anticomplementary method. Immune complexes occurred more often in acute myeloid leukemia (66%) than in pancreatic cancer (23%) or chronic lymphoid leukemia (29%). The immunoglobulin profile of complexes varied: in patients with pancreatic cancer, mainly IgM was found; in leukemic patients--different combinations of IgM, IgA and IgG. In the immune complexes of some patients with pancreatic disease, CEA and normal pancreatic antigens were detected.

The effect of administering increasing intravenous doses of difluoromethylornithine on human tumor cell polyamine levels was determined in patients with hematologic malignancies. Difluoromethylornithine from 5.5. to 64 gm/m2 per day was administered to nine patients with refractory acute leukemia or multiple myeloma. Putrescine, spermidine, and spermine levels were determined on a daily basis in the circulating mononuclear cells and on a weekly basis in the mononuclear cells of the bone marrow. Tumor cell putrescine levels declined in 5 patients, spermidine levels declined in 4 patients, and spermine levels declined in 3 patients. Alterations in the polyamine levels of the bone marrow mononuclear cells paralleled those occurring in the peripheral blood mononuclear cells in the patients with leukemia. Seven to ten days of DFMO treatment were required for mononuclear cell polyamine levels to decrease. The higher drug doses were not significantly more effective than the lower doses in bringing about a decline in tumor cell polyamine levels, either with respect to treatment time required for onset of response or with respect to the ultimate extent of response.

Over the 15-yr period, 1972-1986, 194 episodes of bacteremia occurred in 132 patients with acute leukemia at the Third Department of Medicine, Kanazawa University Hospital, giving an incidence of 478 episodes per 1,000 hospital admissions. This incidence was at least twice as high as that in patients with chronic leukemia, malignant lymphoma, multiple myeloma or aplastic anemia, and about 40-fold higher than that in patients with all other internal diseases. The rate of occurrence of bacteremia, whether unimicrobial or polymicrobial, remained almost unchanged throughout the study period. The frequency of gram-negative bacilli decreased significantly, however, from 81% of the total isolates for the first 10-yr period to 50% for the second 5-yr period. Escherichia coli and Klebsiella pneumoniae were isolated in markedly decreasing frequency, but Pseudomonas aeruginosa and Enterobacter cloacae in relatively constant frequency. The majority of P. aeruginosa isolates belonged to a limited number of O-antigen groups, suggesting the possibility of nosocomial infection. On the other hand, the frequency of gram-positive cocci increased from 9 to 36%. Staphylococcus epidermidis, Enterococcus species, and Staphylococcus aureus emerged as important pathogens. Such a change in the spectrum of organisms was considered to coincide with the common use of the so-called second- and third-generation cephalosporins and central venous catheters. It is thus suggested that vancomycin be added to empiric antibiotic therapy, especially when gram-positive infections are clinically or microbiologically suspected, and that reducing the acquisition of P. aeruginosa from the hospital environment remains a priority in infection prevention.

Platelet aggregation with various inductors and platelet secretion were studied in chronic lymphoid leukemia, myeloma, chronic myeloid leukemia and acute leukemia. It was established that disturbed aggregation with adrenaline and disturbed secretion are found more often in these malignant blood diseases. An interesting fact is that there is no correlation between the disturbed platelet functions in vitro and the clinical manifestations of disturbed hemostasis (hemorrhages or thrombosis).

Therapeutic effects on cefmenoxime hemihydrochloride (CMX, Bestcall), a new synthetic cephem antibiotic, were examined in the treatment of various infections complicated with hematological diseases. The number of patients treated with CMX was 37 including 5 cases of sepsis or suspected sepsis, 14 cases of pneumonia or suspected pneumonia, 5 cases of upper respiratory diseases, 2 cases of urinary tract infections and 11 cases of other infections. All of these infections were complicated with hematological diseases: Acute leukemia, 13 cases; chronic myelocytic leukemia, 1 case; adult T cell leukemia, 3 cases; malignant lymphoma, 8 cases; Hodgkin's disease, 2 cases and myeloma, 3 cases. CMX were administered by a single intravenous injection or by a drip infusion. The dose was between 2 and 6 grams per day. Good to excellent clinical results were obtained in 25 out of 37 cases, total effective rate of 67.6%. No clinical side effects or abnormal laboratory findings attributable to CMX were observed except for light diarrhea in 2 cases. By the clinical investigation, it was demonstrated that CMX was one of safe and effective antibiotics for treating infections in the compromised hosts complicated with hematological diseases.

Peripheral blood cells collected by cytapheresis from patients with acute leukemia following induction therapy or with multiple myeloma off-therapy, were maintained in a one-stage long-term liquid culture system. The data indicate that: (1) blood-derived granulopoietic proliferation can be sustained for up to 8 weeks with generation of CFU-GM in a way similar to bone marrow cells; and (2) this normal hematopoiesis can be sustained in spite of the absence of any development of a substantial stromal adherent layer, which suggests that, unlike hematopoiesis from bone marrow, the blood-derived non-adherent cell population is a self-sustaining compartment. While autologous transplantation with peripheral progenitor cells is gaining importance as an alternative to autologous bone marrow transplantation, this study suggests that circulating progenitor cells may have a different behavior from marrow cells. This observation may be relevant to the understanding of cases of defective hematopoietic reconstitution.

The Seattle Marrow Transplant Team treated about 130 patients (age 4-68 yr) for hematologic cancer with supralethal chemoradiotherapy and bone marrow transplantation (BMT) from the normal genetically identical twin. The procedure was well tolerated. The principal problem was tumor resistance. Nevertheless, BMT for acute leukemia in relapse still cured about 20% of the patients. Moreover, BMT performed while in complete remission cured about 50% of patients with acute lymphocytic leukemia or acute nonlymphocytic leukemia. Sixteen patients received transplantation in the chronic phase of Ph1+ chronic granulocytic leukemia (CGL). All showed disappearance of all Ph1+ cells. Two died of pneumonitis. Of the 14 who are alive, 3 continue to have CGL 37-76 months after BMT and 11 remain in complete hematologic and cytogenetic remission without any Ph1+ metaphases at 31-108 months (median = 68) after BMT. Thus the Ph1-positive clone can be ablated and blast crisis prevented. BMT in the accelerated or blastic phase was far less effective. Syngeneic BMT also benefited or cured patients with lymphoma, hairy-cell leukemia, and multiple myeloma. Therefore, BMT should be considered for every patient who has a hematologic cancer and an identical twin.
