Retrospective analysis of 45 patients (33 females, 12 males) with cytologically-proven malignant ascites is presented. Abdominal pain was the most frequent symptom (69%). Fiftythree percent cases had low serum albumin. Ascitic fluid was haemorrhagic or serosanguinous in 48% cases, in the rest it was clear or straw-coloured. Peritoneal effusion was exudative in 84% cases. Mean glucose content of ascitic fluid was 95 mg/dl and the mean white cell count of 919 cells/cmm. Vast majority (82%) of the cases had metastatic adenocarcinomas. Primary malignancy was mostly ovarian (47%) followed by non-Hodgkin's lymphoma (11%) and gall bladder carcinoma (9%). Primary site could not be identified in 13% cases. Sixty-two percent patients received systemic chemotherapy for the underlying malignancy, of these 43% had complete or partial resolution of the ascites. Of the patients whose long-term follow-up is available, 54% were alive with a median follow-up of 9 months.

Nine cases of pleural fluid infection caused by Listeria monocytogenes (one case described here and eight cases previously reported in the literature) were reviewed. Eight patients (88.9%) had an underlying malignancy (three had Hodgkin's disease, three had non-Hodgkin's lymphoma, and two had leukemia), and six (66.7%) were receiving immunosuppressive therapy at the time of presentation. Seven patients (77.8%) presented with fever and five (55.6%) with respiratory tract symptoms. Those with symptoms of greater than 3 weeks' duration had a relatively poor prognosis. Bacteremia was documented in five patients (55.6%). Examination of pleural fluid typically revealed normal levels of glucose, slightly elevated concentrations of protein, and a negative gram stain. Four patients died, for an overall mortality of 44.4%. Mortality appeared to be lower for patients who received a combination of penicillin or ampicillin plus an aminoglycoside and for those who underwent drainage of pleural fluid than for those not given such treatment. Rapid diagnosis, prompt institution of appropriate antimicrobial therapy, and drainage of the pleural fluid are likely to improve the chances for survival in listerial infection of pleural fluid.

Four men with primary cerebral non-Hodgkin's lymphoma diagnosed by immunocytological analysis of cerebrospinal fluid (CSF) presented with cranial nerve palsies. All had CSF lymphocytoses and low CSF glucose. The cell phenotypes were two T cell tumours, one B cell, and one null. A review of 13 previously recorded cases of immunocytologically diagnosed CNS non-Hodgkin's lymphoma showed that there were 10 B cell, two T cell, and one null tumour. Overall (17 cases) the cell phenotype distribution was 65% B cell, 24% T cell, and 11% null. High CSF lymphocyte counts were found in 94%, proteinosis in 85%, and low CSF glucose in 87%. In contrast to the B cell tumours, all of the T cell tumours were diagnosed by CSF cytology before being visualised radiologically. It is suggested that all CSF lymphocytes (greater than 5 x 10(6)/ml) should be immunohistochemically typed to permit earlier diagnosis of CNS non-Hodgkin's lymphoma.

Patients with lymphomas are conventionally imaged with [67Ga]citrate for tumor detection and determination of dissemination. Fluorine-18-2-fluoro-2-deoxy-D-glucose [( 18F]FDG) is a radiopharmaceutical that accumulates into tissues where glucose utilization is enhanced, such as tumors. Six cancer patients (five non-Hodgkin's lymphomas, one endodermal retroperitoneal sinus carcinoma) were imaged with [18F]FDG and [67Ga]citrate whole-body scintigraphies in order to compare the sensitivities of these two tumor imaging radiopharmaceuticals. Among the five untreated lymphoma patients, two 67Ga scans and four [18F]FDG scans were positive; in the patient with the retroperitoneal carcinoma who had a positive [18F]FDG scan before treatment, both scans were negative after treatment. Fluorine-18 FDG may be a more sensitive tumor-detecting radiopharmaceutical for non-Hodgkin's lymphoma than [67Ga]citrate.

Glucose metabolism has been shown to be increased in neoplastic tissue. It has been suggested that high activity of glucose metabolism is associated with a high grade of malignancy of human cancer. We studied in vivo glucose metabolism in 22 patients with untreated non-Hodgkin's lymphoma with fluorine-18-fluorodeoxyglucose (FDG) and positron emission tomography (PET). FDG uptake in lymphoma deposits was measured blinded to clinical data, and compared with histologic classification and proliferative activity. Tracer uptake was measured by using two indices of FDG accumulation: the standardized uptake value (SUV) and the regional metabolic rate (rMR) for the tracer. The median SUV of the lymphomas was 8.5 (range, 3.5 to 31.0), and the median rMR 22.7 mumol/100 g/min (range, 9.0 to 124.3 mumol/100 g/min). A high FDG uptake in tumors was associated with high histologic degree of malignancy as defined by the Working Formulation (P = .005 for the SUV, and P = .04 for the rMR) or by the Kiel classification (P = .003 for the SUV, and P = .02 for the rMR). A high FDG accumulation was also associated with a high S-phase fraction (r = .786 for the SUV, P = .0002; and r = .774 for the rMR, P = .02). We conclude that in untreated non-Hodgkin's lymphomas high FDG uptake is associated with high histologic grade of malignancy and a high proliferation rate. This minimally invasive method may find application in assessing lymphoma lesions in patients who are poor candidates for surgery, and it may provide further information in cases where the grade of aggressiveness of lymphoma is not settled based on clinical or histologic data.

We report 34 patients (aged 5-18 years) with acute (n = 26) or chronic (n = 1) leukemia, non-Hodgkin's lymphoma (n = 3) or severe aplastic anemia (n = 4) evaluated for pancreatic beta-cell function 9 months to 10.2 years after autologous (n = 19) or allogeneic (n = 15) BMT. Before BMT, all patients received cytotoxic drugs, combined with total body irradiation (TBI) in 24 cases or thoracoabdominal irradiation (TAI) in 4 children. Patients were investigated for fasting blood glucose (FBG), HbA1C, anti-insulin (IAA) and islet cell antibodies (ICA), first-phase insulin response (FPIR) and insulinemia/glycemia (I/G) ratio on i.v. glucose tolerance test (GTT) and C-peptide response after glucagon 1 mg i.v. Results were compared with those obtained in 21 age- and sex-matched controls. None of the patients or controls had IAA and/or ICA. FBG and HbA1C were normal in all children. In the patients, glycemia on i.v. GTT was similar to controls whereas insulin levels I/G ratio and FPIR were significantly higher in patients than in controls, as well as C-peptide levels. We divided the patients on the basis of the radiotherapy into group I with TBI (n = 18), group II with TAI (n = 4) and group III who were not irradiated (n = 4). The I/G ratio, FPIR on i.v. GTT and C-peptide response were significantly higher in group I compared with the other two groups and controls. The increased insulin and C-peptide levels in our patients with normal glycemia might be interpreted as a state of insulin resistance, more evident in patients who received TBL.

A 71-year-old patient with high-grade non-Hodgkin's lymphoma stage IVB, severe lactic acidosis and tumor-associated hypoglycemia is described. Endocrine causes of hypoglycemic episodes were excluded because of low serum concentrations of insulin and "insulin-like growth factor 1", and normal concentrations of growth hormone and thyroid hormone. Clinical conditions associated with lactic acidosis such as diabetes mellitus, biguanide intoxication, septicemia, acute hypoxemia, or circulatory insufficiency were ruled out. Enhanced glucose metabolism within the tumor was visualized by positron emission tomography employing 2-fluro-2-deoxy-D-glucose (FDG) as a tracer. A markedly elevated tumor necrosis factor-alpha (TNF-alpha) level was found which decreased after cytoreductive therapy paralleling the normalization of serum lactate. In contrast to the majority of cases of lymphoma-associated lactic acidoses reviewed to date, in our case lactate elimination was not reduced.

Four patients with non-Hodgkin's lymphoma in the head and neck region were studied with positron emission tomography (PET), using the radioactive tracer 2-[F-18]-fluoro-2-deoxy-D-glucose (18FDG). This technique, which exploits the high metabolic rate of glucose in tumour tissue, enabled the extent of disease to be visualized. The localization of the tumour was improved by combining the data from the PET scan with those from CT scans or MRI. This technique (of PET-18FDG), using visual and semiquantitative analysis in the form of standardized uptake values, allowed the differentiation between reactive hyperplasia and nodal involvement with lymphoma. We believe that PET using the tracer 18FDG may play an important role in the evaluation of patients with head and neck lymphoma.

In a boy with non-Hodgkin's lymphoma (NHL), two different complications developed concurrently associated with L-asparaginase (L-ASP) therapy. A non-ketotic hyperglycemic state was observed simultaneously with bilateral acute parotitis after the patient was subjected to L-ASP. The hyperglycemia with normal insulin levels and the absence of plasma and urine ketones was controlled with insulin therapy and no residual impairment of glucose tolerance was demonstrated later. Bilateral acute parotitis, which is a rare complication associated with L-ASP, resolved spontaneously within a week after cessation of L-ASP. The rarely observed toxic effects of L-ASP, such as parotitis, should be recognized as promptly as the better-known complications, e.g., hyperglycemia, to avoid the continuation of this antineoplastic agent.

We retrospectively evaluated the use of 18F-FDG PET for assessment of residual disease in 27 patients after therapy for malignant lymphoma. The images were evaluated qualitatively and quantitatively using standardized uptake values (SUV). All findings were validated either by biopsy or by clinical follow-up and compared with corresponding CT findings. The impact of blood glucose concentration, body weight, body surface area, lesion diameter and the time between injection and imaging on the SUVs were analysed. All 15 patients with biopsy-proven residual disease or relapse during follow-up and 11 of 12 patients who remained relapse-free were correctly identified by qualitative interpretation of the PET images. A case of pneumonitis after radiotherapy/chemotherapy accounted for the only false-positive finding. Compared with CT imaging, PET had a significantly higher specificity (P < 0.01), accuracy (P < 0.05) and positive predictive value (P < 0.05). The mean and maximum SUV of the tumour lesions were positively correlated to lesion diameter (P < 0.01) and imaging time post-injection (P < 0.01). Standardized uptake values corrected for the partial volume effect and normalized to a standardized imaging time (SUVBPT) were significantly higher (P < 0.05) in high-grade than in low-grade non-Hodgkin's lymphoma. In conclusion, 18F-FDG PET may help in the identification of patients who need additional treatment after the completion of conventional therapy. Qualitative image interpretation appears sufficient for this purpose.
