Previous study has shown that the combination of mitoxantrone (Novantrone, NO) and Ara-C (AC) (NOAC) was active in refractory non-Hodgkin's lymphoma (NHL) but myelosuppression was dose-limiting. In a pilot study, we investigated the effects of recombinant human granulocyte-macrophage colony-stimulating factor (rhGM-CSF) after NOAC chemotherapy in patients with refractory NHL. NO was applied at a dosage of 10 mg/m2/day on days 2 and 3 and AC at 3 g/m2/12h on days 1 and 2. RhGM-CSF was administered at 250 ug/m2/day as a continuous i.v. infusion from day 6 until the neutrophils were greater than 3.0/nl for 3 consecutive days. Twenty-three patients from five of the nine participating centers were treated with NOAC chemotherapy plus rhGM-CSF, whereas 14 patients from the other four centers received chemotherapy alone. With rhGM-CSF, the median duration of severe neutropenia (less than 0.5/nl) after NOAC was 8 days versus a median of 13 days without rhGM-CSF (P = 0.0058), and that of thrombocytopenia (less than 20.0/nl), 3 days versus 7 days (P greater than 0.4, NS). The rates of infections and stomatitis were 25% and 17%, respectively, for patients treated with rhGM-CSF as compared to 53% (P = 0.0547, NS) and 60% (P = 0.0078), respectively, without rhGM-CSF. The following side effects were associated with the administration of rhGM-CSF: pleural and/or pericardial effusions in five patients, thrombosis in two patients, bone pain in two patients, and respiratory distress syndrome in one patient. A complete remission was achieved in nine of the 23 patients treated with NOAC plus rhGM-CSF, and in two of the 14 patients treated with chemotherapy alone. The median survival of patients treated with rhGM-CSF was not reached at 400 days and seemed to be longer than that of patients treated with chemotherapy alone (median, 109 days; P = 0.036). RhGM-CSF after chemotherapy can be applied safely to patients with NHL, shorten the period of severe cytopenia, reduce the rates of stomatitis, and did not seem to cause adverse effects on response.

Combination chemotherapy has dramatically improved the prognosis of patients with intermediate and high grade histologic subtypes of non-Hodgkin's lymphomas. Treatment-related complications, however, are considerable, and a common problem encountered is respiratory distress or respiratory insufficiency. Usually these difficulties have been attributed to infectious etiologies or to chemotherapy-induced interstitial fibrosis, most often involving bleomycin. We describe five patients presenting with respiratory problems several weeks after the initiation of chemotherapy. These patients, who represent 3 percent of all patients treated with a single bleomycin-containing regimen for intermediate or high grade non-Hodgkin's lymphoma, were all initially thought to have chemotherapy-induced interstitial fibrosis but were found on subsequent evaluation to have pulmonary emboli. Of the three patients in whom pulmonary emboli were diagnosed antemortem, two had symptoms suggestive of pulmonary emboli and all were successfully treated and remained well and free of lymphoma for over 24 months. Two additional patients were diagnosed at autopsy. We suggest that pulmonary emboli may contribute significantly to the morbidity and mortality of patients undergoing chemotherapy for non-Hodgkin's lymphoma and recommend that patients presenting with respiratory difficulties be evaluated for pulmonary emboli.

Thirty-six of 915 patients with non-Hodgkin's lymphoma presented with superior vena cava syndrome (SVCS). The histologic types associated with SVCS were diffuse large cell in 23 patients, lymphoblastic in 12, and follicular large cell in one patient. Radiotherapy alone appeared equal to chemotherapy alone or in combination with radiotherapy in achieving relief of SVCS symptoms. Chemotherapy alone or in combination with radiotherapy was superior to radiotherapy alone in prolonging relapse-free survival and overall survival. No differences in relapse-free survival and survival were found between the patients treated with chemotherapy alone and those treated with chemotherapy and radiotherapy, but the addition of radiotherapy appeared to prevent local relapses in the group with large-cell lymphoma. The presence of symptoms of involvement of other mediastinal structures such as dysphagia, hoarseness, or stridor (DHS), a higher grade of intensity, and a shorter duration of symptoms (less than or equal to 2 weeks) appeared to adversely influence relapse-free survival and survival. The following conclusions were made: (1) a histologic diagnosis before the onset of treatment is desirable and feasible in patients presenting with SVCS except in those with severe respiratory distress, (2) both chemotherapy and radiotherapy are equally effective in alleviating the symptoms of SVCS, and (3) combined modality treatment with chemotherapy and radiotherapy results in a lower frequency of local relapses compared to chemotherapy alone but survival was similar in both groups.

40 patients with various forms of malignant disease, who had already been subjected to conventional regimens of treatment, were treated between 1976 and 1981 at the Department of Chemotherapy, Vienna University, with high-dose methotrexate (MTX) as sole therapeutic agent. 18 patients received MTX in moderately high doses of 250 mg/m2 to 750 mg/m2 at 10-day intervals. 19 patients were treated with high doses of 5 to 15 g MTX at 10-day intervals. In 2 cases of severe malignant non-Hodgkin's lymphoma one patient received 2 X 1 g MTX with an interval of 19 days between doses and the other received a single dose of 5 g MTX by infusion. One patient with alveolar soft part cell sarcoma was given ultra-high therapy, with a cumulative dose of 205 g. None of the patients in the group given moderately high-dose MTX therapy, whereas three in the high-dose group had an objective remission. Objective remission was obtained neither in the two lymphoma patients nor in the ultra-high-dose treated case. Complications such as leucopenia and/or thrombopenia were found in 9%, reversible transaminase activity increases in 45%, as well as a decrease in creatinine clearance in 10% of the cases. Irreversible severe kidney insufficiency was found in none of the cases. One patient with lymphoma died as a result of severe toxic epidermiolysis with involvement of the gastrointestinal mucosa, whilst the other suffered from pulmonary complications in the form of the respiratory distress syndrome. On the basis of our experience the use of high-dose MTX therapy as an alternative method following trials of all conventional regimens is not recommended.

Pulmonary microvascular tumor embolization is a recognized cause of respiratory distress in cancer patients that is rarely diagnosed antemortem. Previous studies with relatively few patients have reported high diagnostic yield using wedged pulmonary artery catheter-derived blood samples to evaluate dyspneic cancer patients for possible microembolization. From 1991 to 1993, 21 cancer patients with respiratory distress of relatively acute onset and varying severity who required pulmonary artery catheterization for hemodynamic monitoring were evaluated using this technique. Pulmonary microvascular cytology (PMC) was interpreted as positive for malignant cells in nine of 21 patients presenting with a range of tumor types, including carcinomas of the breast, colon, and pancreas as well as non-Hodgkin's lymphoma. In 11 patients the PMC was interpreted as negative. One case was considered nondiagnostic. Megakaryocytes, noted in most PMC specimens as well as in several samples of simultaneously drawn peripheral blood, may mimic epithelial tumor cells. Immunocytochemical stains for factor VIII and cytokeratins were used to resolve occasional diagnostic dilemmas. Clinical and/or pathologic follow-up information was available for all patients. Diagnostic accuracy was highest for epithelial malignancies. Two false-negative results occurred in patients with metastatic choriocarcinoma and breast carcinoma. Circulating malignant cells in the peripheral blood of a patient with non-Hodgkin's lymphoma led to one false-positive diagnosis. Benign lymphoid elements in PMC generally have a reactive and variable appearance that should not be misinterpreted as lymphoma. We conclude that PMC is a useful tool in the evaluation of dyspneic cancer patients requiring pulmonary artery catheterization for hemodynamic monitoring and its use potentially avoids additional diagnostic procedures.

We report here a case of acute polymyositis associated with a Ki-1 non-Hodgkin's lymphoma (NHL). This anaplastic large cell malignant lymphoma was a primary T-cell NHL lymphoma of the bone marrow. The malignant cells expressed the CD30 (Ki-1), CD3, and CD4 antigens, the beta chain of the interleukin 2 receptor (CD25), and the betaF1 antigen (alpha/beta T-cell receptor). Chemotherapy and high dose methylprednisolone pulse therapy were initiated. However, no clinical improvement was noticed, because the patient rapidly died of an acute respiratory distress syndrome. To our best knowledge, this represents the first case of Ki-1 lymphoma associated with Polymyositis.

From January 1999 to May 2000 (17 months), 21 strains of streptococci and four strains of enterococci have been isolated from 74 blood cultures in 25 infectious episodes in hematologic patients. They concerned 21 patients, of 21 to 77 years old. These patients suffered from acute leukaemia (14 cases), chronic lymphoid leukaemia (two cases), non-Hodgkin's lymphoma (two cases) or myeloma (three cases). Seventeen patients displayed a single streptococcal or enterococcal episode, two had two episodes in the course of a single stay in the hospital, two others in the course of two different stays. During 16 episodes (64%), the bacteremia occurred within 15 days after the onset of neutropenia consecutive to antimitotic chemotherapy, and in nine episodes (36%) it has occurred after a period exceeding 15 days. In six cases the patients had already received antibiotics with a large antibacterial activity (beta-lactam, fluoroquinolone and/or glycopeptide +/- aminoside) and in four cases a single antibiotic (synergistine or cotrimoxazole). Most streptococci (20/21) were oral streptococci (ten Streptococcus mitis, five S. oralis, two S. sanguis, three S. pneumoniae). A single strain of beta-hemolytic streptococci has been identified as S. dysgalactiae subsp. equisimilis. The enterococci were one strain of Enterococcus faecalis and three E. faecium. Ten streptococci were susceptible to 0.25 mg/L of penicillin G, ten were less susceptible (0.5 < or = MIC < 32 mg/L), and a strain was resistant (MIC = 32 mg/L). Eighteen strains were susceptible to amoxicillin and cefotaxime. For three strains, the MICs of amoxicillin and cefotaxime (8-16 mg/L and 8-32 mg/L, respectively) were higher. Levels of resistance of the enterococci to the beta-lactam (penicillin, amoxicillin, and piperacillin) were variable. All species were susceptible to glycopeptides. Three patients were transferred in intensive care unit for respiratory distress or shock syndrome. Their evolution has remained severe under antibiotherapy comprising beta-lactam or vancomycin associated with an aminoside. This results demonstrate the interest of species identification to adapt the antibiotic treatment and confirms the frequency of oral streptococci in severe bacteremia in neutropenic patients.

Transfusion-related acute lung injury (TRALI) has been implicated with use of almost all types of blood products that contain variable amounts of plasma. Even though the reported incidence of TRALI is rare, its overall occurrence is thought to be more common, as less severe cases remain unreported. More TRALI cases are unrecognized and misdiagnosed due to lack of suspicion and absence of appropriate investigation. There are exceedingly rare reports of TRALI during plasma exchange despite the fact that liters of plasma may be used for replacement during a single procedure. We describe a mild case of TRALI during plasma exchange for thrombotic thrombocytopenic purpura in a 56-year-old woman, status post autologous hematopoietic stem cell transplant for non-Hodgkin's lymphoma. She developed severe rigors, peripheral cyanosis, hypoxia, and a transient diffuse pulmonary infiltrate. Of the 10 U of plasma used, one was from a multiparous female donor with HLA antibodies reactive with patient's granulocytes in immunofluorescence and agglutination assays. This case emphasizes the fact that the physicians and apheresis staff should consider TRALI in the differential diagnosis for patients developing respiratory distress during or soon after the procedure. Diagnosing TRALI has implications not only for the plasma exchange recipient, but also for the management of donors found to have leukocyte antibodies.

This study explored the efficacy and toxicity of the combination of pentostatin and rituximab, effective single agents in low-grade non-Hodgkin's lymphoma (NHL). Sixty patients with previously treated low-grade NHL were enrolled. Except for day 1, both drugs were administered weekly for 4 weeks, with week 5 off. During week 1 (day 1) only rituximab was given; subsequent weekly treatments included both drugs. Patients received a minimum of 2 five-week cycles in order to be evaluable for efficacy. Responses were evaluated on week 5 of cycle 2. If partial response (PR) or stable disease (SD) responses were noted, 2 additional cycles were administered. Final evaluations were done on week 5 of cycle 4. Of 60 patients, 58.3% had an Eastern Cooperative Oncology Group performance status (PS) of 0, and 41.7% had PS of 1; 31.7% and 51.7% had stage III or stage IV disease, respectively. Histology included follicular center, follicular, grade I (45%), II (21.7%), III (1.7%), and small lymphocytic (31.7%). Seventeen patients had prior chemotherapy, but no patients had received prior pentostatin or rituximab. Median age was 60.3 years (range, 32.5-84.7 years). Among 57 evaluable patients, 77% responded (22.3% complete response [CR], 3.5% unconfirmed CR, 35.1% PR, and 10.5% unconfirmed PR); 19.3% had SD, and 8.8% progressive disease (PD). Response rate among previously untreated patients was 83% versus 63% in previously treated patients. Median duration of response was 11 months (range, 2.3-22.2 months); median time to progression was 15 months (range, < 1-25 months). Neutropenia was the only adverse event experienced by >/= 10% of patients. Six deaths were caused by PD, and one death each was caused by acute respiratory distress, possibly related respiratory failure, and cardiac toxicity. These results suggest the combination of pentostatin/rituximab is well tolerated and active in low-grade lymphoma.
