A therapeutic trial of recombinant human granulocyte-macrophage colony-stimulating factor (rhGM-CSF) was attempted in a patient with neutropenia and frequent infections secondary to T-gamma lymphoproliferative disease (T-gamma LPD). During the 14 days of subcutaneous rhGM-CSF (500 micrograms/m2/day), the absolute eosinophil count increased from 0 to 9,455/microliters. By contrast, the absolute neutrophil count decreased. Toxicity related to rhGM-CSF included arthralgia and nonspecific chest pain. The possible mechanism for the rhGM-CSF induced selective eosinophilia is discussed.

To evaluate the toxicity and efficacy of recombinant human granulocyte-colony-stimulating factor (rh G-CSF) administered with intensive chemotherapy, 39 patients with advanced pulmonary cancers were enrolled in a dose escalation trial of rh G-CSF. Three days after initiation of chemotherapy rh G-CSF was administered i.v. for 14 consecutive days at five dose levels (50-800 micrograms/m2). Absolute neutrophil counts showed a dose-dependent increase with an increasing dose of rh G-CSF and the durations of neutropenia (less than 1000/mm3) shortened significantly at doses of 200, 400, and 800 micrograms/m2 compared to those at 50 micrograms/m2 (P less than 0.01). The duration of neutropenia was shortened significantly at all five dose levels following treatment with rh G-CSF compared to treatment without rh G-CSF (P less than 0.05). Adverse side effects associated with rh G-CSF administration were fever higher than 38 degrees C (21%), chest pain, and low back pain (13%). No intolerable side effects were experienced. It can be concluded that rh G-CSF is effective in shortening the duration of neutropenia following intensive chemotherapy at a dose level of 100 to 200 micrograms/m2 i.v. a 400-micrograms/m2 dose of rh G-CSF is recommended in patients with prior treatment because of the possibility of a lower bone marrow response.

A 88-year-old man was admitted because of the left chest pain due to herpes zoster for 1 week. Blood analyses and immunoelectrophoresis revealed anemia, severe neutropenia, rouleaux formation and IgM, lambda-type monoclonal gammopathy. The HE staining and peroxidase-anti-peroxidase staining of biopsy specimens of the cervical lymph node swelling appeared from the fifth hospital day, revealed an increase in atypical lymphocytes bearing IgM, lambda-type immunoglobulin. Then a diagnosis of primary macroglobulinemia was made. Although the patient's clinical findings transiently improved after chemotherapy with prednisolone and vindesine, he died of a septic shock which appeared after klebsiella pneumonia and sepsis. We reported an unusual case of primary macroglobulinemia with severe neutropenia, leading to a rapid development of septic shock after the chemotherapy.

Thirteen patients with relapsed or refractory Non-Hodgkin's Lymphoma were treated with 131I-Lym-1 during the course of a dose escalation trial. Principal aims were to establish the maximum tolerated single dose (MTD), as well as to assess clinical and dosimetric effects of the MTD. Patients were eligible if > 25% of tumor cells bound Lym-1 on immunohistochemistry, stain intensity was +2/4 or greater and human anti-mouse antibody (HAMA) assay was negative. Radioimmunotherapy was performed with escalating doses at levels of 50 mCi, 65 mCi/m2 and 80 mCi/m2 (50-139 mCi total). Patients were eligible for retreatment after 6-10 weeks if there was no severe toxicity, their disease was at least stable and HAMA remained negative. Three were retreated. Four have achieved partial responses which lasted 11, 11, 18 and 22 weeks. Acute toxicities included rigors (69%), fever (62%), nausea (46%), vomiting (46%), pruritus (23%), urticaria (23%), chest pain (23%) and bronchospasm (15%). HAMA developed in 3 patients. Myelosuppression, manifested as thrombocytopenia and neutropenia, was dose-limiting and defined the single dose MTD at 65 mCi/m2. Plasma radioactivity clearance was biphasic, with a 0.9 hr alpha-T1/2 and a 19.8 hr beta-T1/2. At completion of Lym-1 infusion, a mean of 45% of the injected dose was recoverable in the circulation. Images obtained within the first 2 hours indicated mean hepatic and splenic uptake was 29% and 11%, respectively. Radiation absorbed doses to tumor ranged from 18-61 rads; mean doses to whole body ranged from 17 to 71 rads.

A nineteen-year-old woman whose Hodgkin's disease had relapsed experienced acral erythema in association with a asymptomatic pericardial friction rub following autologous bone marrow transplantation. An echocardiogram revealed a large pericardial and right pleural effusion. Since blood cultures gave negative results, renal function was normal, and the patient had neither neutropenia nor elevated temperature, an infectious cause was deemed unlikely and invasive procedures were not performed. These effusions resolved spontaneously. We propose that this patient's acral erythema and associated pericardial and pleural inflammation represent cutaneous and serosal toxic reactions to high-dosage chemotherapy that occur with the onset of leukocyte recovery. If so, acral erythema may signal the beginning of a toxic drug reaction. The appearance of erythema associated with lymphocyte recovery is due to immune hypersensitivity secondary to immaturity of the reconstituting immune system. Thus, we recommend that patients with acral erythema be examined for pleuropericarditis, especially if they experience chest pain.

Ticlopidine is a powerful antiplatelet activator that inhibits adenosine diphosphate (ADP)-induced platelet aggregation. Its most common side-effects are skin rashes, diarrhea and neutropenia. Aplastic anemia is rare. This paper reports a patient with severe aplastic anemia that developed after the use of ticlopidine. The 85-year-old woman developed fever, chills and chest pain 5 weeks after starting ticlopidine 250 mg twice daily. Severe aplastic anemia was proved by blood examination, bone marrow aspiration and biopsy. In spite of the recovery of absolute neutrophil count to more than 1,000/mm3, 16 days after ticlopidine was stopped and administration of strong antibiotics, the patient died from candidal sepsis.

A phase I/II study was carried out to determine the maximum tolerated dose of paclitaxel (Taxol; Bristol-Myers Squibb Company, Princeton, NJ) in combination with a fixed dose of carboplatin (area under the concentration-time curve = 6 by Calvert method) given on an every-3-week schedule to patients with non-small cell lung cancer (NSCLC). Cohorts of patients were entered at increasing dose levels of paclitaxel: six at dose level I (paclitaxel 150 mg/m2), six at dose level 2 (paclitaxel 175 mg/m2), 11 at dose level 3 (paclitaxel 200 mg/ m2), 21 at dose level 4 (paclitaxel 225 mg/m2), and five at dose level 5 (paclitaxel 250 mg/m2). The patients comprised 31 men and 18 women with a median age of 62 years (age range, 46 to 81 years) and a median Southwest Oncology Group performance status of I (range, 0 to 2). Twenty-three patients had unresectable stage III NSCLC and 26 had stage IV NSCLC. Fortynine patients and 176 treatment courses are evaluable for toxicity. Grade 4 neutropenia or grade 3 arthralgias/ myalgias or sensory neuropathy were the most significant toxicities of therapy. In addition, two patients (dose levels 2 and 3) experienced acute chest pain, flushing, and hypotension, and had electrocardiogram changes during the paclitaxel infusion; one had mild creatine phosphokidnase MB elevation. Both recovered uneventfully, were not re-treated with paclitaxel, and account for two of only four hospitalizations for toxicity management in this trial. At this time, 42 patients with objectively measurable disease are evaluable for responses: two complete responses and 24 partial responses (62% objective response rate) have been observed. These data imply that the maximum tolerated dose of paclitaxel is 250 mg/m2 with dose-limiting toxicity consisting primarily of grade 3 osteo/arthralgias-myalgias or cumulative sensory neuropathy; paclitaxel at a dose of 225 mg/m2 given by 3-hour infusion combined with carboplatin at a calculated target area under the concentration-time curve of 6 is a well-tolerated outpatient treatment regimen and highly active in NSCLC; myelosuppression is mild and rarely dose limiting. Most notably, paclitaxel appears to decrease carboplatin's pharmacodynamic effects on thrombopoiesis.

Invasive pulmonary aspergillosis is an opportunistic infection occurring in a background of severe immune depression. The majority of cases occur in patients who have malignant hematologic disease, particularly during chemotherapy induction or consolidations phases for acute non-lymphocytic leukemia. The principal risk factors are profound (PN < 500 per mm3) and prolonged (very high risk beyond 20 days) neutropenia, perturbed phagocyte function and cellular immune deficiency (AIDS, immunosuppressive treatment in organ and bone marrow recipients). Clinically, invasive pulmonary aspergillosis presents as acute non-specific pneumonia with cough, chest pain and fever. The severe infection rapidly becomes life-threatening. The development of massive hemoptysis is a major risk. We report four cases of invasive pulmonary aspergillosis in patients who had hemoptysis. All four patients developed non-specific pneumonia resistant to broad-spectrum antibiotics during post-chemotherapy aplasia. Computed tomography of the thorax and bronchoscopy with bronchoalveolar lavage was performed due to the occurrence of hemoptysis. In the first two cases, the patients were recovering from aplasia. The thoracic CT scan showed evidence of a cavitating mass with peripheral vessels. Bronchoscopy findings suggested mucosal lesions. The patients were managed surgically. Pathology confirmed the diagnosis of invasive pulmonary aspergillosis with the presence of ischemic necrosis of the pulmonary parenchyma harboring numerous aspergillus filaments. Outcome was favorable and chemotherapy was re-initiated in one case. These two patient died from their hematological disease a few months later. The other two patients remained in aplasia. A CT of the thorax showed multifocal infiltration with vascular contact. Bronchoscopy was again suggestive. One patient developed massive hemoptysis with respiratory distress. Embolization was performed but the patient died two days after onset of hemoptysis. In the last case, embolization was successful and outcome was favorable enabling a bone marrow allograft; the patient died a few months later from the hematological disease. The potential gravity of hemoptysis in the course of invasive pulmonary aspergillosis should lead to early treatment with emergency CT scan and, if possible, bronchoscopy with bronchoalveolar lavage to establish the therapeutic strategy based on surgical excision or embolization of the pulmonary or bronchial arteries.

The aim of the present phase II study was to assess the activity and safety of gemcitabine-cisplatin combination in advanced NSCLC, and to evaluate the impact of this regimen in terms of symptom benefit and quality of life (QOL). Eighty patients with pathologically confirmed advanced (stage IIIB and IV) NSCLC were enrolled into this study. Gemcitabine was administered on days 1, 8 and 15 at a dose of 1000 mg/m(2), and cisplatin was given on day 2 at a dose of 100 mg/m(2). The cycles were repeated every 4 weeks. The impact of treatment on QOL and on tumor-related symptoms was evaluated with the validated EORTC forms (QLQ-C30 and LC-13). The regimen was relatively well tolerated. Myelosuppresion was the principal toxicity. Grade 3/4 neutropenia, thrombocytopenia and anemia occurred in 58, 65 and 30% of patients respectively. In 143 cycles (35%) the administration of gemcitabine on day 15 was omitted due to myelosuppresion. Non-hematological toxicities were generally mild. Among the 76 patients available for response evaluation, there were 5 complete responses (7%) and 26 partial responses (34%); an overall response rate of 41%. The median duration of response was 8.0 months. The median survival for all 80 patients was 11.0 months and the actuarial 1-year survival probability 45%. During therapy global QOL improved in 22% of patients and particular functional domains increased in 19-37% of patients. Dyspnea was released in 36% of patients, fatigue in 45%, chest pain in 38%, shoulder pain in 27%, cough in 44%, and hemoptysis in 75%. The mean intensity scores of the last three symptoms decreased significantly with therapy. Our study confirmed relatively high efficacy of the gemcitabine-cisplatin combination in patients with advanced NSCLC. Of particular importance was that treatment with gemcitabine-cisplatin combination in a large proportion of patients was also associated with remarkable symptomatic release and with improvement of QOL. However, the high frequency of myelotoxicity-related gemcitabine omissions on day 15 of the cycle indicates that modification of the schedule should be considered in standard care.

XR 5000 is one of a series of tricyclic carboxamide-based cytotoxic agents. It binds to DNA by intercalation and stimulates DNA cleavage by inhibition of both topoisomerase I and II, thus possibly overcoming the resistance resulting from downregulation of either enzyme. Twenty patients with advanced or metastatic colorectal cancer, unpretreated for metastatic disease, received XR 5000 at the dose of 3010 mg/m(2) in a 120-h central intravenous (i.v.) infusion every 3 weeks. Response was evaluated every two cycles. No complete (CR) or partial responses (PR) were observed in eligible patients (response rate, 0 of 19, 0%; 95% confidence interval (CI): 0-18%). 5 patients had stable disease, which lasted from 79 to 157 days. Haematological toxicity was low, since only one grade 4 neutropenia and two grade 3 anaemia were observed. Other treatment-related grade 3-4 toxicities were: deep venous thrombosis (2 cases), liver toxicity, diarrhoea, anorexia, dyspnoea, chest pain, infection (1 case each). Despite the good toxicity profile, these results do not support further trials with XR 5000 in metastatic colorectal cancer.
