    Notes: Abstract Objective To evaluate the safety of tracheotomy in neutropenic ventilated cancer patients, in terms of infectious and haemorrhagic complications. Design Retrospective study. Setting A medical-surgical intensive care unit in a Cancer-hospital.Patients and participants: 26 consecutive patients undergoing a tracheotomy in neutropenic period, from 1987 to 1990. Interventions Tracheotomy, performed at the bedside or in operating, room. Measurements and results In all neutropenic patients undergoing a tracheotomy, the characteristics and duration of both neutropenia and mechanical ventilation have been recorded. Stomal bleeding and infection, and infectious pneumonias and alveolar haemorrhage have been carefully reviewed. Platelets were transfused in 23 of the 26 patients at the time of the procedure; no local haemorrhage was observed. Neither stomal nor pulmonary infections secondary to traceotomy were noted. No respiratory worsening was attributable to the tracheotomy. Nineteen patients (73%) died in ICU, without direct link between tracheotomy and death. Conclusions These findings suggest that a tracheotomy can be safely performed in neutropenic patients requiring mechanical ventilation.

    Notes: Abstract In a 39-year-old patient under follow-up for metastatic adenocarcinoma of the colon, a post-operative fever and a profound neutropenia occurred during hospitalization. A diagnosis of primary infection with parvovirus B-19 was made in view of the association of reticulocytopenia, together with anti-B19 IgM antibodies and positive serum results for viral DNA. The granulocytic lineage appeared to be normal on bone-marrow smears, and anti PMN autoantibodies were not found. Rh G-CSF therapy resulted in a sharp increase in the PMN count. Although the pathophysiology of B19-associated neutropenia remains unclear, Rh G-CSF seems to be effective in this disorder.

    Notes: Summary The pharmacokinetics of high-dose busulfan given orally at 1 mg/kg every 6 h over 4 days (total dose, 16 mg/kg) in combined chemotherapy followed by autologous bone marrow transplantation was studied in 12 children with a mean age of 7 years (range, 4–14 years). Busulfan levels in biological fluids were measured by a gas chromatographic assay with mass fragmentographic detection, using a deuterated analogue as the internal standard. In a high-dose regimen, busulfan followed one-compartment model kinetics with zero-order absorption. A mean maximal concentration of 803±228 ng/ml was achieved at 92–255 min after dosing. The mean elimination half-life was 2.33 h, and the mean total clearance was 119±54 ml/min per m2, with an apparent distribution volume of 27.10±11.50 l/m2. A mean trough level of 370 ng/ml was found throughout the 4 days of the chemotherapy course. There were no significant variations in pharmacokinetic parameters measured after the first and last doses. Busulfan was monitored in the CSF of nine children at 3.25–7 h after the last dose and was detected in all patients, with a mean CSF-to-plasma concentration ratio of 0.95 (range, 0.5–1.4).

    Notes: Summary Vindesine (VDS) has been submitted to a phase-II trial, the results of which were assessed in terms of regression induction. VDS was given weekly IV in doses of 2 mg/m2 on two consecutive days to 59 patients, 55 of whom were evaluable. A high proportion of complete (36%) and over 50% partial regressions were obtained in acute lymphoid leukemias (ALL) (overall response 63%) whatever the perceptible phase, in blastic crisis of chronic myeloid leukemia (55%), and some responses were recorded in lymphosarcoma (40%). No effect has so far been seen in acute myeloid leukemia or in Hodgkin's disease. Malignant neoplasms of the immunoblastic type seem to be particularly sensitive to VDS. Continuous 48 h IV infusion can induce a remission where an IV push administration of the same dose has failed. One remarkable characteristic of VDS is the apparent absence of cross-resistance with VCR: in acute leukemic forms, 55% of patients who failed to obtain remission induction after three weekly injections of VCR (used in combination chemotherapy) achieved a complete or partial remission with VDS. The toxicity was mainly neurologic (paralytic ileus, constipation, paresthesias, loss of reflexes) and hematologic (leukopenia and thrombopenia), and was not more significant than with the other agents: four patients died of infection or hemorrhage.

    Notes: Summary Fifteen patients received irradiation after combined chemotherapy with high-dose busulfan followed by autologous or allogeneic bone marrow transplantation. Of nine patients irradiated between day 30 and day 70 after their engraftment, seven developed an increased radiation response in the skin: four showed enhanced reactions during irradiation, and three had a total or severe definitive alopecia more than 16 months after CNS irradiation. Six patients were irradiated after day 70; they had either normal reactions or none at all within the cutaneous radiation portals. The possibility that busulfan might be a radiosensitizer is raised.

    Notes: Summary Seventy-five patients were treated for short periods with BCG either per os (7), by aerosols (2), i.d. with needles, i.d. with heaf-gun, on one or four scarification areas, i.v., or intratumorally. Two hundred and seventy-seven were treated for more than 3 years by BCG applied scarifications. The local reactions after application on scarification are negligible, the most frequent being pruritus and adenopathies. The systemic reactions are due to the BCG septicemia which is induced and which has been proved by the search for liver granulomas. Some reactions are of an allergic nature (e.g., choroiditis), but most are direct manifestations of the septicemia (fever, hepatomegaly, splenomegaly). One death was observed after tumoral injection in a terminal patient, otherwise there were no deaths, even in the patients under long-term treatment with the other metabolites. Deterioration of immune reactions may be induced either by the method of BCG application which is followed by a (probably) very small penetration (on scarified area in allergics), or by the penetration of high doses (four scarified areas in anergics and intravenous injections in anergics and in allergics).

    Notes: Summary Protocol ICIG-ALL 9 with only nine months' remission chemotherapy followed by active immunotherapy has given a proportion of about 50% of the patients on the plateau of the first remission curve, while 60% of the children are on the plateau of survival curve. These results do not differ from those of another protocol (ICIG-ALL 10) conducted on an identical population of patients and comprising a 25 month remission chemotherapy before immunotherapy. This observation, confirmed by a randomized trial of the EORTC Haemopathy Working Party, suggests that between the 9th and the 25th month, active immunotherapy is as efficient as maintenance chemotherapy. The overall results of this protocol with short chemotherapy followed by active immunotherapy have been compared with those of another prolonged maintenance chemotherapy before immunotherapy protocol (ICIG-ALL 11), and with published protocols comprising only long maintenance chemotherapy: protocol 9 is, as far as the first remission plateau and the survival plateau are concerned, superior to most of these protocols (if not all their branches). Lethal toxicity of active immunotherapy is nil, in contrast to the proportion of deaths (4–28%) occurring during remission in the patients submitted to maintenance chemotherapy. However, not all patients with so-called acute lymphoid leukaemias should be treated identically: our early prognosis parameters (WHO cytological types and volume of the tumour, in this study) allow us to distinguish a good prognosis group in which protocol 9 gave an 80% cure expectancy. The patients with a poor prognosis should be the object of further research for a more efficient therapy. Even if this should be more intensive, the risk is justified in this group, while it is not so for the good prognosis group.

    Notes: Abstract Background: Fludarabine was associated with a good response and was well tolerated in patients with follicular lymphoma in phase II trials and this treatment may be associated with less adverse events than treatment with CHVP plus interferon in elderly patients. Patients and methods: One hundred thirty-one patients older than 59 years with a follicular lymphoma and poor prognosis were randomized between the association of CHVP (12 cycles in 18 months) plus interferon (5 MU TIW for 18 months) or fludarabine alone (25 mg/m2/d ×5 days for 6 cycles, then 20 mg/m2/day for 6 further cycles for 18 months). Poor prognosis was defined by the presence of a large tumor mass, poor performance status, the presence of B symptoms, above normal LDH level, or ≥3 mg/l β-microglobulin level. Results: Patients treated with CHVP plus interferon had a higher response to treatment, a longer time to progression and a longer survival than those treated with fludarabine alone (P 〈 0.05 for all analyses). With a median follow-up of 29 months, the 2-year failure-free survival was 63% for the CHVP-plus-interferon arm compared to 49% for the fludarabine arm and the two-year survival was 77% and 62%, respectively. This benefit was confirmed in a multivariate analysis including initial prognostic parameters. Fludarabine alone was associated with less neutropenia than CHVP plus interferon. Interferon was decreased or stopped in 39% of the patients because of severe fatigue. Conclusions: CHVP plus interferon over 18 months was associated with a better outcome, even though the combination of interferon plus chemotherapy was less well tolerated than fludarabine.
