Twenty-three children with various stages and morphologic types of leukemia were treated with multiple granulocyte transfusions obtained by filtration leukapheresis when neutropenia-associated infection appeared unresponsive to antibiotics. All children meeting the above qualifications were given granulocyte transfusions during this time period. Twenty-one of 23 became afebrile during or shortly after the transfusions; one died with disseminated Herpes simplex; and one became well enough to be discharged, although he was never free of fever. Frequent mild to moderate fever and chills were noted. One child developed a severe pulmonary reaction followed by resolution of pneumonia. Filtration leukapheresis is a useful adjunct in controlling severe infections in neutropenic children.

Ten episodes of Torulopsis glabrata fungemia occurring in nine patients with terminal illnesses are described. Eight patients had underlying malignancies and one patient had a plastic anemia. Two episodes of fungemia were considered transient since they were clearly related to the administration of intravenous hyperalimentation (IVH). Most patients were adult women and had solid tumors of the genitourinary tract. Contributory factors were: antibiotic therapy (100%), immunosuppressive drugs (75%), abdominal surgery (63%), IVH (50%), neutropenia (38%), and diabetes mellitus (13%). The clinical course was indistinguishable from a severe bacterial infection. However, endotoxic shock was not observed. The infection was rapidly fatal in four patients. In the remaining five patients, the infection was altered favorably by the discontinuation of infected intravenous hyperalimentation catheters. However, tissue invasion by T. glabrata was found in two of these patients who died shortly thereafter from tumor progression. At autopsy, T. glabrata was identified in tissue sections of the lungs, kidneys, and mucosas of the gastrointestinal and genitourinary tracts. In all cases there was tissue necrosis with a minor inflammatory response consisting of mononuclear cells. To our knowledge, this is the single largest series of T. glabrata fungemia ever reported.

Methyl-CCNU, a compound with marked antitumor activity against the solid Lewis lung tumor in mice, was submitted to a preclinical pharmacologic evaluation. The toxicity of a single iv infusion was tested in 37 beagle dogs and 21 rhesus monkeys. The minimum lethal dose (LD) in dogs was 14 mg/kg and five of six dogs died within 7-10 days after treatment from hematopoietic toxicity with neutropenia, lymphopenia, anemia, and concomitant sepsis. Metaplasia of the intestinal epithelium also occurred. Thrombocytopenia was not observed. Dogs treated with 9.27-1.56 mg/kg exhibited reversible neutropenia and lymphopenia but survived without severe morbidity or histopathologic lesions. In monkeys, interstitial nephritis was the treatment-limiting toxicity and three of six monkeys treated with 45 or 30 mg/kg died, became moribund, or exhibited severe renal histopathologic lesions. One monkey treated with 45 mg/kg had degeneration of the testes. Survivors exhibited reversible toxicity and no histopathologic lesions. Treatment with doses as low as 7.5 mg/kg caused reversible neutropenia, lymphopenia, and anemia. The largest nontoxic dose for a single iv infusion was 3.12 mg/kg (62.40 mg/m2) for the dog and 3.75 mg/kg (45 mg/m2) for the monkey. These and earlier observations showed that methyl-CCNU had approximately one third the toxicity of CCNU. Methyl-CCNU also did not cause the delayed hepatic toxicity which is characteristic of CCNU treatment in the dog.

The toxicity produced by two courses of methotrexate separated by different intervals has been studied in matched groups of rats. The maximum degree of neutropenia reached when courses were separated by 8 days or more was no greater than that seen after a single course of methotrexate. However, when courses of neutropenia following the second course of methotrexate was directly related to the level of depression of bone marrow cell numbers at the time of the second course. Conversely the anti-leukaemic effects of 2 courses of methotrexate, in terms of time of onset of leukaemia and time of death in rats transplanted with a syngeneic T-cell leukaemia, are shown to be similar when courses of methotrexate are separated by between 2 and 12 days. Thus in this system, chemotherapeutic schedules using methotrexate may be designed on the basis of minimal host toxicity without prejudicing anti-leukaemic effects. These results are discussed in relation to toxicity and anti-leukaemic effects observed during UKALL trials of treatment in acute lymphoblastic leukaemia.

A group of 49 patients with advanced non-Hodgkin's lymphoma were entered in a combination-chemotherapy protocol (cyclophosphamide L2). Of 14 patients with diffuse poorly differentiated lymphocytic lymphoma (DPDL), 64% responded with two partial remissions (PR) and seven complete remissions (CR). Both PRs are stable at 17+ months while six of the CR group are free of disease at 3+-23+ months. Fifty-three percent of 30 patients with diffuse histiocyctic lymphoma (DHL) responded with 23% attaining CR status. Of the nine PR patients, six are stable at 11+-23+ months while six of the seven CR group are without disease at 9+-27+ months. The major toxic effect was bone marrow suppression with two deaths during periods of neutropenia; one of these deaths was definitely drug related. The encouraging results in the DPDL category have led to a continuation of this protocol for patients with this histologic type. In patients with DHL other approaches are being explored.

Pulmonary aspergillosis in patients with leukemia or lymphoma is usually a fatal infection. However, difficulty in obtaining a premortem diagnosis has often prevented an adequate trial of anti-fungal chemotherapy. In this report, nine cases of aspergillus pneumonia in patients with hematologic malignancy were diagnosed during a one-year period. Five of nine patients had a premortem diagnosis (56%) and eight of nine (89%) received a premortem trial of amphotericin B. Two of nine patients survived infection, including one patient with prolonged neutropenia. Better diagnostic methods and wider use of antifungal chemotherapy may improve prognosis for aspergillus infection in patients with hematologic malignancy.

The peripheral blood changes were studied in 67 children who received craniospinal irradiation for posterior fossa tumors. At the completion of a cranial dose of about 3500 rad to the whole brain port, the lymphocytes were reduced to 858/mm3 rom 3084/mm3 preoperatively. The counts of the remaining leukocytes stayed at a level somewhat higher than preoperatively; the eosinophils rose to 288/mm3 from 125/mm3. With the initiation of the spinal field irradiation, which included a large proportion of the total bone marrow, the numbers of all the leukocytes decreased rapidly; the observed leukopenia was mainly secondary to neutropenia. A mechanism that was operating to restore the number of leukocytes became manifest immediately after the completion of radiotherapy, though the number of lymphocytes had not been totally restored to the preoperative level 6 years later. Irradiation of the lymphocytes that circulate through the vascular bed can explain the lymphopenia observed during cranial radiotherapy. Mild leukopenia observed in patients receiving radiotherapy through a relatively small port may be secondary to lymphopenia, and this does not necessarily indicate impaired bone marrow reserves.

The records of 360 patients with malignant lymphoma treated with various forms of combination chemotherapy from 1966 to 1974 were reviewed. A total of 181 infections was found in 125 patients. The most frequent types of infection were pneumonia (31%), skin infections (17%), urinary tract infections (13%) and septicemia (11%). An etiologic organism was was identified in 133 infections (73%). The most common causative organisms were bacteria (77%), especially gram-negative bacilli. Viral infections accounted for 18% of the infections with 21 of the 24 being due to herpes zoster. These were more frequently found in patients with Hodgkin's disease (14/21) than in the other lymphomas. Among patients with Hodgkin's disease, 53% treated with COP developed infections compared to only 27% treated with MOPP (p = 0.039). Among patients with non-Hodgkin's lymphoma, infections were more frequent in patients treated with Adriamycin containing combinations than with COP. Neutropenia (i.e. less than 1,000 neutrophils/mm3) was associated with 35% of infections in this study and was seen more often in patients with non-Hodgkin's lymphoma (p = 0.048).

Human bone marrow obtained from patients with neutropenia contains a cell population which is absent or diminished in normal marrow. The abnormal population is composed of cells of volume 200-300 mum3 which sediment at 5-5 to 8-5 mm/h. Normal marrow contains one cell class giving rise to increased numbers of grnaulocyte colonies after mass culture, while marrow obtained from neutropenic patients, or from patients with marrow regeneration, shows two such populations; one of these cell classes corresponds to the abnormally large cells demonstrated on velocity sedimentation analysis. This population of large cells may represent a group of either self-renewing cells related to the committed granulocyte progenitors or the pluripotent stem cell.

The safety and efficacy of tobramycin and cephalothin in treatment of suspected sepsis were studied in neutropenic children with various malignancies. Twenty episodes of suspected sepsis in 19 febrile children with cancer were treated with parenteral tobramycin and cephalothin; the duration of therapy ranged from one to 80 days. In 14 of the 20 episodes of suspected sepsis, a favorable clinical response was achieved within five days after initiation of antibiotic therapy. These episodes included a urinary tract infection with Proteus mirabilis and sepsis due to Escherichia coli. In four of the additional six episodes, clinical deterioration was though to be caused by the underlying malignancies. Two episodes included a case of E. coli spesis that ended fatally and a nosocomial infection with Eikenella corrodens. Results of this study suggest that combination therapy with tobramycin and cephalothin is safe and efficacious in treatment of suspected sepsis in febrile children with malignancies and neutropenia.
