Serum neuron-specific enolase (NSE) was evaluated in a number of malignant tumours. It was elevated (greater than 12.5 micrograms l-1) in 13/17 (76.5%) patients with extensive small-cell lung carcinoma and in none of the three patients with limited disease. Of patients with carcinoma of the breast 4/12 (33.3%) had elevated concentrations. Normal concentrations were found in patients with non-Hodgkin's lymphoma (19) and Hodgkin's disease (15), carcinoma of the cervix (2), CSF and serum (5) of patients with gestational trophoblastic disease (with definite nervous system involvement). Comparative serial studies of NSE and carcinoembryonic antigen (CEA) concentrations were done in 15 patients with small-cell lung cancer (SCLC). Of these 7/15 (46.7%) had elevated pre-treatment concentrations of both CEA and NSE, 1/15 (6.7%) had CEA elevated only, while 2/15 (13.3%) had NSE alone elevated. Of those patients with normal pre-treatment marker concentrations 3/5 (60%) had elevated markers on recurrence. The mean survival period was 61.9 weeks; 66.8 weeks for the marker-negative group and 44.6 weeks for the marker-positive (both NSE and CEA) group. Combined NSE and CEA evaluation provide additional means of monitoring SCLC.

Considering the good penetration of systemic high-dose ara-C (HDara-C) into the CNS, we used this approach for treating overt meningeal leukemia, either isolated or with concurrent extraneurologic disease, in 15 adults with high-risk acute lymphoblastic leukemia (ALL), one adult with lymphoid blast crisis of chronic granulocytic leukemia (LBC-CGL), and four adults with poor-prognosis non-Hodgkin's lymphoma (NHL). Treatment consisted of ara-C, 3 g/m2 every 12 hours by three-hour infusion for eight doses followed by a second course of four doses on day 21. Remitters received consolidation with monthly courses of HDara-C for four doses. Additional systemic multi-drug reinduction therapy and direct CNS treatment with intrathecal methotrexate (IT MTX) and cranial irradiation (CRT) was administered to the three remitters last treated. Thirteen of 20 patients (65%) achieved complete remission (CR): seven of seven patients with isolated meningeal leukemia and six of 13 patients with concurrent CNS and bone marrow disease. Of the remaining seven patients, five had a complete CSF clearing with persistent marrow disease. In all cases there was prompt resolution of neurologic signs and symptoms. The median duration of CR was 5 months (range 2 to 8 months). The most significant toxicity seen was myelosuppression, which was predictable and manageable. Nonhematologic toxicity was generally acceptable and included moderate nausea and vomiting, diarrhea, drug fever, transient liver dysfunction, and dermatitis. No cases of CNS toxicity occurred. There were no treatment-related deaths. Disease-free survival was limited by marrow relapse, either isolated or with concurrent CNS disease. No instances of isolated meningeal relapse occurred. These results obtained in a poor-risk subset of patients indicate that HDara-C is an effective treatment for the induction of remission in ALL and NHL with meningeal leukemia. Therefore, HDara-C should be considered for inclusion in multiagent consolidation programs for patients at high risk for CNS disease.

The concentration of beta-2-microglobulin (beta 2-m) and of post gamma globulin (P gamma G) was examined in serum and cerebrospinal fluid from children with acute lymphatic leukemia (ALL) and non-Hodgkin's lymphoma (NHL). Data were analysed in order to determine whether concentration of beta 2-m or P gamma G during remission would be of value in predicting relapse or eventual outcome. Mean serum concentration of beta 2-m was similar in good and poor prognosis patients with ALL in remission and was not significantly altered in CNS or marrow relapse. Mean CSF concentration in NHL was also similar in both prognostic groups, and in poor prognosis patients was not significantly altered in relapse. The same pattern was seen when P gamma G was measured in CSF (serum concentration of this protein being too low for accurate determination). High within patient variability of levels of beta 2-m and P gamma G appeared to relate to chemotherapy rather than the disease process. Concentration of P gamma G was persistently raised in three children with brain damage of differing etiologies. Levels of two other low molecular weight proteins, retinol binding protein and alpha 1-microglobulin, were also determined in order to establish that beta 2-m and P gamma G concentration was not influenced by alteration in permeability of the blood-brain barrier. The beta 2-m and P gamma G concentration, although higher than reported in healthy children [5] does not appear to be of value as a prognostic indicator in ALL and NHL in children.

A patient with non-Hodgkin's lymphoma who was previously treated with chemotherapy and radiotherapy was seen with intestinal pseudoobstruction due to paralytic ileus associated with herpes zoster (varicella zoster) infection. The infection was accompanied by a polydermatomal rash with typical morphologic characteristics, followed by cutaneous dissemination and the syndrome of inappropriate antidiuretic hormone (SIADH), as well as myotomal paresis. The diagnosis was supported by cytology and by culture of the virus from the CSF. The isolation of the virus from the CSF, coupled with abnormalities of the patient's mental status and CSF, indicate that meningoencephalitis occurred and probably accounted for the SIADH. The patient had a spontaneous and complete recovery. To our knowledge, this is the first report of SIADH associated with herpes zoster infection.

The pathophysiology of cerebral tumor mass in cases of systemic non-Hodgkin's lymphoma is not well known. We experienced with two cases with this lesion. The purpose of this report is not only case presentation but also an analysis of cases from the literature from the clinical, radiological, histological, immunological and therapeutic aspects. Case 1 was a 82-year-old man who had weakness in the right arm and for the past month. For about two years he had been received anticancer chemotherapy because of a systemic malignant lymphoma at another hospital. Neurological examination revealed disorientation and right hemiparesis. Microscopic and immunological studies of the biopsy specimen of the enlarged supraclavicular node showed a non-Hodgkin's B-cell lymphoma of the diffuse large cell type according to the Lymphoma Study Group (LSG) classification. The clinical stage (CS) of the lymphoma was IV except for the CNS lesion by systemic examination including lymphography. CT scan on admission revealed remarkable enhancement of a nodular high density area near the lateral ventricle, accompanied by surrounding low density. Angiography failed to reveal a tumor stain. CSF cytology was positive although no pleocytosis was observed. Case 2 was a 70-year-old man who had weakness of the right foot for two weeks. About three years ago he underwent orchiectomy for a testicular tumor at another hospital. Neurological examination revealed disorientation, memory loss and right hemiparesis.(ABSTRACT TRUNCATED AT 250 WORDS)

CT was performed on 72 children with acute lymphoblastic leukemia or non-Hodgkin's lymphoma. Thirty-two of these patients were investigated prior to CNS radiation and intrathecal methotrexate therapy. Ten of these patients (31%) were known to have hydrocephalic dilatation of the CSF spaces. Clinical data and subsequent observations with analysis of the CT findings show that no difference in the attenuation values of brain tissue occurs in the absence of a CNS relapse. The percentage of abnormal findings before and after therapy remains constant. The adverse late effect described in the CT literature seem principally to be damage diagnosed too late. It is questionable if the CT demonstration of dilated CSF spaces before treatment has a prognostic significance.

Primary central nervous system lymphoma (PCNSL) is rare, accounting for only 1-2% of non-Hodgkin's lymphoma, and primary isolated leptomeningeal lymphoma is even rarer. It may create a diagnostic problem, particularly when the tumor cells are of T cell lineage. We herein report a patient with primary T cell leptomeningeal lymphoma. The final diagnosis was confirmed by the cytogenetic study which revealed clonal aberration, isochromosome of long arm of chromosome 7, in the lymphoid cells from CSF. She was treated with a novel protocol of systemic chemotherapy specifically designed for the CNS lymphoma. The regimen consisted of carmustine, vincristine, high-dose methotrexate, etoposide, and methylprednisolone. A total of 5 courses were given and she was still in complete remission at the time of reporting, 21 months after the establishment of diagnosis.

G-CSF and GM-CSF enhance the rate of neutrophil engraftment in autologous bone marrow transplantation (ABMT) without significantly affecting platelet engraftment. Peripheral blood progenitor cells (PBPC) may enhance rates of engraftment of both neutrophils and platelets. We treated 49 patients undergoing ABMT with a course of G-CSF to obtain PBPC and infused these cells post-transplant with G-CSF in an attempt to determine factors which might correlate with enhanced BM engraftment. Forty-nine patients with Hodgkin's disease, non-Hodgkin's lymphoma or breast cancer undergoing unpurged ABMT were studied. G-CSF priming consisted of an outpatient 8 day course of 5 micrograms/kg/day followed by three leukaphereses (on day 5, 7 and 8) to collect PBPC. Patients then received a chemotherapeutic BMT preparative regimen followed by an infusion of PBPC, autologous BM and the reinstitution of G-CSF (16 micrograms/kg/day). BM engraftment was rapid. The median time to achieve 0.5 x 10(9)/l neutrophils was 10 days compared with a historical BMT control patient population receiving the same preparative regimens of 19 days (p = 0.001). Time to achieve a platelet count of 20 x 10(9)/l was 16 days compared with a historical control of 22 days (p = 0.001). Neutrophil engraftment occurred in all patients by day +14. Marrow engraftment correlated with the total number of CD34+ cells infused as well as the total number of mononuclear cells infused but not the total number of CD34+/CD33- cells infused. The amount of total blood volume pheresed significantly correlated with yield of total mononuclear cells. Prior exposure to radiation therapy negatively correlated with progenitor cell yield.(ABSTRACT TRUNCATED AT 250 WORDS)

This report summarizes our results of sequential treatment with IL-3 and GM-CSF following high-dose chemotherapy with respect to the yield and composition of peripheral blood stem cells (PBSC). Eight patients with high-grade non-Hodgkin's lymphoma were included in the study. Starting 24 h after high-dose cytosine arabinoside (Ara C)/mitoxantrone, IL-3 was given for 6 days, followed by GM-CSF. The increase of circulating hematopoietic progenitor cells during leukocyte recovery varied substantially from patient to patient. Up to a 22-fold interindividual difference was observed for the peak levels of CD34+ cells. A special focus of our study was the antigenic profile of the CD34+ PBSC. On analysis of the antigenic profile of the CD34+ cells, the proportion of CD34+/HLA-DR- and CD34+/CD38- cells representing non-committed hematopoietic stem cells was consistently < 5%. The vast majority of CD34+ cells was found to coexpress CD33 (86.3 +/- 2.1%, mean +/- SEM), reflecting myeloid lineage commitment. CD71 antigen was present on 47.4 +/- 3.0% CD34+ cells with two populations (CD71dim/bright), while the percentage of early B lymphoid (CD34+/CD19+) progenitor cells was extremely low (0.38 +/- 0.13%). We therefore conclude that the cytokines currently available such as G-CSF, GM-CSF or IL-3 facilitate an ontogenetic phenomenon supporting the redistribution of hematopoietic progenitor cells after cytotoxic treatment. Six patients were autografted with the IL-3/GM-CSF-exposed blood stem cells following high-dose conditioning therapy. It is worth noting that no additional BM or hematopoietic growth factors were given post-transplantation.(ABSTRACT TRUNCATED AT 250 WORDS)

For patients with advanced-stage or poor-prognosis malignant lymphoma, high-dose therapy with peripheral blood progenitor cell (PBPC) support may become a first-line treatment. The duration of severe cytopenia in this setting is inversely related to the number of PBPCs autografted. In a retrospective analysis, we therefore looked for factors influencing the yield of PBPCs in 61 patients (16 with high-grade and 29 with low-/intermediate-grade non-Hodgkin's lymphoma [NHL], and 16 with Hodgkin's disease) who received cytotoxic chemotherapy and filgrastim (R-metHuG-CSF, 300 micrograms/d; median, 4.2 micrograms/kg/d; range, 2.7 to 6.6 micrograms/kg/d; subcutaneously). Sixteen patients had active disease, while 45 were in partial remission (PR) or complete remission (CR) after conventional therapy. A median of three leukaphereses (range, one to 10) resulted in a median of 5.7 x 10(6) CD34+ cells/kg (range, 0.03 to 31.1 x 10(6)). Previous cytotoxic chemotherapy and irradiation adversely affected the yield of CD34+ cells. Each cycle of chemotherapy is associated with an average decrease of 0.2 x 10(6) CD34+ cells/kg per leukapheresis in nonirradiated patients, while large-field radiotherapy reduces the collection efficiency by an average of 1.8 x 10(6)/kg CD34+ cells. The collection efficiency was also significantly lower in patients with Hodgkin's disease. However, except for one, all had been previously irradiated. In contrast, age, sex, disease status, bone marrow involvement during mobilization, and the time since the last chemotherapy or radiotherapy were not significantly related to the collection efficiency. Following high-dose conditioning therapy, 42 patients were autografted with filgrastim-mobilized PBPCs. Hematological recovery (neutrophils > or = 0.5 x 10(9)/L and an unsupported platelet count > or = 20 x 10(9)/L) within 2 weeks was observed in patients autografted with > or = 2.5 x 10(6) CD34+ cells/kg. In seven patients, the quantity of CD34+ cells reinfused was below this threshold. They required a median of 17 days (range, 11 to 34) and 31 days (range, 13 to 141) for neutrophil and platelet recovery, respectively. If autografting with PBPCs in malignant lymphoma with poor prognosis is being considered, mobilization and harvesting should be planned early after initial diagnosis to avoid exhaustion of hematopoiesis by cumulative toxicity.
