Abstract
If a translocation is followed by loss of one of the two derivative chromosomes, the result is an unbalanced translocation, showing monosomy for the segments making up the lost derivative. We have found that in most unbalanced translocations, a third event takes place: a morphologically normal copy of one of the two translocation participants is added to the karyotype. This creates a complex abnormal karyotype with monosomy, disomy, and trisomy for different segments of the translocation participants. We have examined 82 unbalanced translocations from 77 patients, 73 of whom had a myeloid hemopoietic malignancy. Acquisition of a normal copy of a translocation participant was found in 49 translocations. Twenty-five of these showed trisomy for 1q. In 16 of the 25 1q-trisomic cases the translocation was t(1;7)(q10;p10) (trisomy for 1q and monosomy for 7q). Patients with trisomy for 1q were younger than the remaining patients. Whereas those with t(1;7))(q10;p10) showed brief survivals, those with trisomy 1q but monosomy for regions other than 7q survived longer than the remaining patients. We conclude that most unbalanced translocations involve a partial trisomy, that 1q is trisomic far more frequently than any other segment, and that partial trisomy is associated with patient age and survival.

Abstract
Of 560 consecutive, newly diagnosed untreated patients with B CLL submitted for chromosome study, G-banded karyotypes could be obtained in 480 cases (86%). Of these, 345 (72%) had normal karyotypes and 135 (28%) had clonal chromosome abnormalities: trisomy 12 (+12) was found in 40 cases, 20 as +12 alone (+12single), 20 as +12 with additional abnormalities (+12complex). Other frequent findings included abnormalities of 14q, chromosome 17, 13q and 6q. The immunophenotype was typical for CLL in 358 patients (CD5+, Slg(weak), mainly FMC7-) and atypical for CLL in 122 patients (25%) (CD5-, or Slg(strong) or FMC7+). Chromosome abnormalities were found significantly more often in patients with atypical (48%) than in patients with typical CLL phenotype (22%) (P < 0.00005). Also +12complex, 14q+, del6q, and abnormalities of chromosome 17 were significantly more frequent in patients with atypical CLL phenotype, whereas +12single was found equally often in patients with typical and atypical CLL phenotype. The cytomorphology of most of the +12 patients was that of classical CLL irrespective of phenotype. In univariate survival analysis the following cytogenetic findings were significantly correlated to a poor prognosis: chromosome 17 abnormalities, 14q+, an abnormal karyotype, +12complex, more than one cytogenetic event, and the relative number of abnormal mitoses. In multivariate survival analysis chromosome 17 abnormalities were the only cytogenetic findings with independent prognostic value irrespective of immunophenotype. We conclude that in patients with typical CLL immunophenotype, chromosome abnormalities are somewhat less frequent at the time of diagnosis than hitherto believed. +12single is compatible with classical CLL, and has no prognostic influence whereas chromosome 17 abnormalities signify a poor prognosis. In patients with an atypical CLL immunophenotype, chromosome abnormalities including +12complex, 14q+, del 6q and chromosome 17 are found in about 50% of the patients, and in particular chromosome 17 abnormalities suggest a poor prognosis.

Abstract
In 1991 we reported the results from a prospective randomised phase 3 trial comparing 7 days continuous infusion of cytosine arabinoside (ara-C) combined with either daunorubicin (DNR) or aclarubicin (ACR) as direct i.v. injection for 3 days as induction chemotherapy (CT) for patients with de novo acute myeloid leukemia (AML) followed by early intensive consolidation CT with two alternating cycles of high-dose ara-C and two cycles of amsacrine plus etoposide, and finally 3 days of daunomycin plus 7 days of ara-C as administered for induction of remission. A total of 174 patients with de novo AML in the age group 17-65 years were included. The patients have now been followed till death or for at least 7 years, and an evaluation of the long-term survival and the risk of developing secondary neoplasms has been made. The overall survival rate 5-years after diagnosis was 23%, and after 10 years 19%. No difference was found between the two treatment regimens in overall survival or disease-free survival (DFS). For the subgroup of 99 patients who achieved complete remission after one or two induction courses, 5- and 10-year survival rates were 35% and 31% respectively, with the highest survival rates in the age group 17-39 years (57% at 5 years) as compared with 27% in patients aged 40-60 years (P= 0.007). Seven secondary neoplasms were diagnosed simultaneously with or after the diagnosis of AML indicating a standardized incidence ratio (SIR) of 3.41, (95% CI: 1.60-7.26). In three cases the secondary neoplasms were diagnosed simultaneously with the AML diagnosis and were for that reason completely unrelated to the chemotherapy administered for AML, as the psammomatous meningeoma diagnosed after only 8 months. The remaining three neoplasms which developed subsequently did not significantly exceed the expected number, with a SIR = 1.46 (0.47-4.57). Thus, no increased risk of solid tumors causally related to the intensive chemotherapy for de novo AML was observed. However, a generally increased risk of solid tumors in patients diagnosed simultaneously with the AML diagnosis seems likely. Over 20% of the patients were alive and in complete remission 5 years after the AML diagnosis, and they have a high probability of surviving the next 5-year period.

Abstract
Relapses after autologous transplantation are a serious clinical problem in patients with haematological diseases. The decision making for handling of such patients is difficult and the aim of this retrospective analysis of posttransplant relapses was 1) to obtain information of practical importance for the management of future relapses and 2) to evaluate the basis for clinical phase I-II trials of salvage therapy combined with biological modifiers. Included in the study were 283 patients with acute leukemia, multiple myeloma and malignant lymphoma who relapsed after autologous transplantations during a five year period from 1989 to 1994. Chemo- and radiotherapy was given to 229 patients after relapse or due to progressive disease and the response evaluated after 90 days. Fifty four patients (24%) obtained a complete remission and 44 patients (19%) partial responses. The overall median survival from relapse was 5 months. In the group given salvage treatment the median survival was 7 months and in the 54 patients who obtained remission the median survival was 15 months. So far 6 of 14 patients in continuous complete remission have a remission time after relapse longer than the time in remission after transplantation. Survival after relapse depended upon the time from transplantation to relapse, primary disease and if salvage therapy was given. In conclusion posttransplant relapses can be treated but the strategy has to be evaluated in future clinical trials.

Abstract
In a multicentre study of 635 consecutive newly diagnosed patients with B-CLL, the histological bone marrow (BM) specimens were reviewed independently by each of 3 pathologists and found evaluable for BM infiltration pattern in 575 patients, 404 of whom had a CD5+, mainly FMC7-, faint surface-membrane immunoglobulin (SIg) fluorescence-intensity ppenotype. In these 404 patients the following BM infiltration patterns were found: mixed nodular-interstitial (30%), moderate interstitial (44%), heavy interstitial (20%) and diffuse packed (6%). In univariate survival analysis, significant differences were found according to BM pattern (p < 0.05), the presence of nodules being a favorable prognostic sign. In multivariate survival analysis in a model including age, clinical stage, BM pattern, BM lymphocytosis, WBC and sex, only age and stage but not BM pattern or BM lymphocytosis had independent prognostic significance. In stage A, progression-free survival was significantly longer in patients with nodular than in patients with non-nodular bone-marrow pattern. The overall survival of these patients, however, did not differ, possibly owing to the prompt and prolonged treatment given to most patients at the time of progression to stage B or C. We conclude that in CD5+, SIg(faint), mainly FMC7-B-CLL, bone-marrow histology may predict unstable disease in early clinical stage but is not important for treatment decisions, when these are based on clinical stage.

Abstract
In a Danish population-based non-Hodgkin's lymphoma (NHL) registry (LYFO) representing a population of 2.7 million all new cases of NHL were registered from 1st January 1983 to 31st May 1994. Incidence data of primary malignant tumours of the brain and central nervous system in western Denmark for the period 1971-1990 have been obtained from the Danish Cancer Registry. During the approximate 11-year period 3124 new cases of NHL were registered. Of these, 1152 (37%) were extranodal and 48 were non-AIDS related primary central nervous system lymphomas (PCNSL) accounting for 4.2% of extranodal NHL and 1.5% of all NHL, respectively. The average annual incidence rate of non-AIDS related PCNSL during the period was 1.56 cases per million population (age range: 15-85 yrs, median: 62 yrs, M/F ratio: 1). In a 23-year period there was no trend towards an increasing incidence of non-AIDS related PCNSL in a well-defined population. PCNSL accounted for 1.7% of all primary malignant brain tumours. Incidence of primary malignant brain tumours was stable, except for age ranges over 70 years. Histologically, 85% were high grade, centroblastic diffuse (60%) and immunoblastic lymphoma (13%) (Kiel classification). No T-cell lymphomas were detected. Treatment included surgical resection, whole brain irradiation (WBRT) and chemotherapy. Median survival for those receiving either WBRT or WBRT and chemotherapy was eight months and 20 months, respectively (p = 0.78). Overall survival was 53%, 38% and 26% at one, two and five years. Cox-regression analysis identified only one factor having independent impact on survival in performance score > or = 2 (PCNSL p < 0.001, RR = 5.8).

Abstract
A consecutive cohort of patients with NHL was examined to identify the factors predictive of CNS-involvement with Cox's proportional hazards model in a multivariate analysis. Twenty-seven cases of CNS-involvement were found among 498 patients with NHL. Only 3 of 96 patients with low-grade lymphomas had CNS involvement, all occurring after transformation into high-grade lymphoma. In univariate analysis of 402 patients with intermediate or high-grade lymphoma, lymphoblastic histology (including Burkitt's lymphoma), age <35 years, B-symptoms, stage IV disease, testis involvement and bone marrow involvement were found to be statistically significant risk factors. Lymphoblastic histology was found to be strongly correlated to age younger than 35 years. In the multivariate analysis only lymphoblastic histology, stage IV disease and B-symptoms were found to be significantly associated with CNS involvement. It is concluded that CNS prophylaxis should be considered in all patients with lymphoblastic histology and in patients with stage IV B lymphomas other than those of low-grade types.

Abstract
It has been claimed that Primary Central Nervous System Lymphomas (PCNSL), a rare neoplasm accounting for only a small fraction of malignant brain tumors and extranodal non-Hodgkin lymphomas (NHL), occur with increasing frequency in immunologically normal as well as in immunocompromised individuals. In an attempt to characterize the clinicopathological features, outcome and prognostic factors of PCNSL we here report our experience in a large unselected series of patients from a well-defined region. In addition, we present data on trends in incidence of PCNSL and primary malignant brain tumors in a well-defined geographical area. In a Danish population-based NHL registry (LYFO) representing a population of 2.7 million all new cases of NHL were registered during the approximate 11-year period from 1st January 1983 to 31st May 1994. Incidence data of primary malignant tumors of the brain and central nervous system in western Denmark for the period 1971-1990 have been obtained from the Danish Cancer Registry. During the approximate 11-year period 3124 new cases of NHL were registered. Of these, 1152 (37%) were extranodal and 48 were non-AIDS related PCNSL accounting for 4.2% of extranodal NHL and 1.5% of all NHL, respectively. The average annual incidence rate of non-AIDS related PCNSL during the period was 1.56 cases per million population (age range: 15-85 yrs, median: 62 yrs, M/F ratio: 1). In a 23-year period there was no trend towards an increasing incidence of non-AIDS related PCNSL in a well-defined population. PCNSL accounted for 1.7% of all primary malignant brain tumors. Incidence of primary malignant brain tumors was stable, except for age ranges over 70 years. However, diagnostic artifacts might be responsible for this apparent increase. Histologically, 85% were high grade. Using the Kiel classification centroblastic diffuse (60%) and immunoblastic lymphoma (13%) were the most common subtypes. Forty-three patients had B-cell lymphoma and no T-cell lymphoma was detected. Forty-seven cases were diagnosed pre mortem. Treatment included surgical resection (26 patients), whole brain irradiation (WBRT) (43 patients) and chemotherapy (28 patients). Median survival for those receiving either WBRT or WBRT and chemotherapy was 8 months and 20 months, respectively (p = 0.78). Overall survival was 53%, 38% and 26% at 1, 2 and 5 years. Cox-regression analysis identified only one factor having independent impact on survival in PCNSL: performances score > or = 2 (p < 0.001, RR = 5.8).

Abstract
PURPOSE To evaluate incidence, time trends, geographic distribution, clinicopathologic presentation features, and prognostic factors for survival and relapse in gastrointestinal (GI) non-Hodgkin's lymphomas (NHLs). PATIENTS AND METHODS Over a 9-year period (1983 to 1991), 2,446 new NHL cases were recorded in a Danish population-based NHL registry (Danish Lymphoma Study Group [LYFO]). Of these, 306 (12.5%) were GI NHL (175 gastric, 109 intestinal, and 22 both sites). LYFO registry data were used for incidence rate (IR) assessment, and time-trend and geographic distribution analysis. Relative risk (RR) values for survival and relapse were identified by multivariate analysis. RESULTS The mean annual, age-standardized IRs for gastric and intestinal NHL were 0.71/10(5) and 0.48/10(5) per year, respectively. Age-specific IRs for both localizations showed an exponential increase as a function of age. Time-trend analysis for the period 1983 to 1991 showed stable IRs for both localizations. Intestinal NHL was more frequent in males (male-to-female ratio, 2.0 v 1.3), and had a higher occurrence of disseminated disease, constitutional symptoms, high-grade histology, and T-cell phenotype (10% v 2%). Gastric NHL had more low-grade cases (38% v 19%), and almost all were of the mucosa-associated lymphoid tissue (MALT) type. The cause-specific 5-year survival rate was 63% for gastric NHL and 49% for intestinal NHL. The Musshoff staging system was an excellent discriminator between truly localized (stage I and II1) and disseminated cases (stage II2 to IV), particularly for gastric NHL, for which no survival difference was found between surgically and conservatively stage localized cases. CONCLUSION (1) No increase in the incidence of GI NHL was found over a 9-year observation period; (2) nonrandom spatial distribution of new GI NHL cases was observed; (3) factors that significantly increased the risk of death in gastric cases were presence of B symptoms (RR = 3.3), clinical stage is more than II1 (RR = 3.0), age more than 72 years (RR = 2.4), and elevated serum lactate dehydrogenase (s-LDH) level (RR = 2.0); and factors that increased the risk of death in intestinal cases were presence of B symptoms (RR = 3.2), age more than 58 years (RR = 2.8), and clinical stage more than I (RR = 2.1); (4) factors that significantly increased the risk of relapse in gastric cases were male sex and no radiotherapy in primary treatment; and in intestinal cases were T-cell phenotype and no surgery in primary treatment; (5) surgical staging, as opposed to thorough noninvasive staging, did not improve staging accuracy and final outcome in localized gastric NHL.

Abstract
BACKGROUND Primary Central Nervous System lymphomas (PCNSL), a rare neoplasm accounting for only a small fraction of malignant brain tumors and extranodal non-Hodgkin's lymphomas (NHL), seems to occur with increasing frequency in immunologically-normal as well as immunocompromised individuals. In an attempt to characterize the clinicopathological features, incidence rate and outcome of PCNSL, we here report our experience in a large unselected group of patients from a well-defined region. PATIENTS AND METHODS In a Danish population-based NHL registry (LYFO) representing a population of 2.7 million, all new cases of NHL were registered during the 10-year period from 1st January 1983 to 31st December 1992. The number of malignant brain tumors reported to the Danish Cancer Registry from the region covered by LYFO, during the 7-year period from 1st January 1983 to 31st December 1989, is compared to the number of PCNSL. RESULTS During the 10-year period 2687 new cases of NHL were registered. Of these, 1004 (37%) were extranodal and 42 were non-AIDS-related PCNSL, accounting for 4.2% of extranodal NHL and 1.6% of all NHL, respectively. The incidence rate for PCNSL during the ten-year period (age range: 21-85 yrs, median: 62 yrs, M/F ratio: 0.9) was 15.6 cases per million population. Eighteen and 24 cases were diagnosed during the first and the second 5-year period, respectively (p > 0.05). During the 7-year period 1866 primary malignant brain tumors were registered in the region covered by the LYFO study group. In the same period 30 cases of PCNSL were detected. Thus, PCNSL accounted for 1.6% of all primary malignant brain tumors diagnosed in Western Denmark. Histologically, 83% were high-grade. Using the Kiel classification centroblastic diffuse (62%) and immunoblastic lymphoma (12%) were the most common subtypes. Thirty-seven patients had B-cell lymphoma; no T-cell lymphomas were detected. Forty-one cases were diagnosed pre mortem. Treatment included surgical resection (23 patients), whole brain irradiation (WBRT) (37 patients) and chemotherapy (22 patients). Median survival for those receiving either WBRT or WBRT and chemotherapy was 7.5 months and 12 months, respectively (p > 0.05). Survival was 43.9%, 31.7% and 7.3% at 1, 2 and 5 years.

Abstract
During the period January 1983 to January 1988 1597 newly diagnosed cases of non-Hodgkin's lymphoma (NHL) were included in a Western Danish population-based NHL registry. Of these, 31% (N = 496) were low-grade NHL (LG-NHL) consisting of (Kiel): 9% lymphocytic (LY), 27% lymphoplasmacytic/-cytoid (IC), 53% follicular centroblastic/-centrocytic (CB/CCf) and 11% unclassifiable low-grade. LG-NHL (age range: 26-94 yrs, median: 64 yrs; M/F ratio: 0.8) had an age-standardised incidence rate (IR) of 2.7/10(5)/yr. Age-specific IR's showed an age-related exponential rise in all subtypes except for CB/CCf. Compared with the intermediate (IG)- and high-grade (HG) group, LG-NHL had more female cases (M/F ratio: 0.79 vs. 1.2; p = 0.0002), a higher frequency of stage III-IV disease (66% vs. 53%; p < 0.00005) and of bone marrow involvement (39% vs. 19%; p < 0.00005). A later revision of all IC cases (N = 132) distinguished 79 non-polymorphic (ICnp) from 25 polymorphic (ICp) cases; 28 cases were differently classified. In 34 LG-NHL patients histologic transformation was verified: CB/CCf to CB diffuse (22 pts) and LY to immunoblastic or CB type (6 pts). The 7-yr survival for LG-NHL was 63% (IG: 48%, HG: 38%; p < 0.00005). A Cox-regression analysis identified the following adverse prognostic factors for survival in LG-NHL: age > 50 with a relative risk (RR) of 3.2, hepatic involvement (RR = 2.1), elevated s-LDH (RR = 1.9), B-symptoms (RR = 1.8) and IC histology (ICnp+ICp) (RR = 1.7).(ABSTRACT TRUNCATED AT 250 WORDS)

Abstract
Within a seven year period, 1597 newly diagnosed cases of non-Hodgkins lymphoma (NHL) were included in a Danish population-based NHL-register. Of these, 602 (38%) were aged 70 or older (age range 70-94, median: 76.8) and represented the population defined as "elderly" patients in the present study. Their average annual incidence rate was 35.7/10(5), as compared to 6.6/10(5) for patients aged < 70 (overall annual incidence: 9.5/105). Localised cases (stage I and II) and extranodal manifestations were more frequent among elderly patients. The most common sites of extranodal involvement were stomach (21% of all extranodal cases) and bone marrow (16%). Histologically, follicular centroblastic/centrocytic cases were found to be less frequent (p < 0.01) in elderly patients as compared to their younger counterparts (< 70 years), who on the other hand had a lower occurrence of diffuse centroblastic cases (p < 0.01). Overall seven year survival for the elderly patient population was 35% (median: 1.7 years), and for patients aged < 70 it was 57%. This difference persisted after correction for apparently NHL-unrelated deaths (52% vs. 66% respectively, p < 0.0001). The following poor prognostic factors for elderly patients were identified by multivariate analysis: hepatic involvement, presence of B-symptoms, high-grade histology and elevated s-LDH. The corresponding relative risk values were respectively 2.4, 2.2, 1.9 and 1.6.

Abstract
The aim of this paper was to present the results of bone marrow harvest followed by cryopreservation in 22 children with various malignant diseases, and the clinical course of autologous bone marrow transplantation (ABMT) performed in 10 children (three with acute lymphoblastic leukemia (ALL), three with acute myeloblastic leukemia (AML) and four neuroblastoma stage IV (NB)). In 20/22 children the harvested bone marrow contained a sufficient number of granulocyte-macrophage-colonyforming units (GM-CFU) for later marrow reinfusion. Hematological reconstitution was obtained in all 10 children who underwent ABMT. No child died of toxicity. The median time to neutrophil count > 0.5 x 10(9)/l, thrombocyte count > 50 x 10(9)/l and to discharge from hospital were 34, 49 and 29 days respectively. Five children are alive with no evidence of active disease 11-21 months after ABMT. Five children have suffered relapse and have died. It was concluded that sufficient amounts of precursor bone marrow cells may be harvested in children during a pause in cystostatic therapy. The acute toxicity of ABMT in children with malignant diseases was only moderate.

The most common sites of extranodal involvement were the stomach (21% of all extranodal cases) and the bone marrow (16%). Histologically, follicular centroblastic/centrocytic cases were found to be less frequent (p less than 0.01) in elderly patients as compared to their younger counterparts (less than 70 years), who in contrast had a lower occurrence of diffuse centroblastic cases (p less than 0.01). Overall 7-year survival for the elderly patient population was 35% (median 1.7 years), and for patients aged less than 70 it was 57%. This difference persisted after correction for apparently NHL-unrelated deaths (52% vs. 66%, respectively, p less than 0.0001). Elderly patients with poor prognosis were characterised by the following features identified in a Cox-regression model: hepatic involvement, presence of B-symptoms, high-grade histology and elevated s-LDH. The corresponding relative risk values were in the order 2.4, 2.2, 1.9 and 1.6.

Abstract
Blood mononuclear cells from 540 newly diagnosed, unselected patients with B-cell chronic lymphocytic leukemia (CLL) were examined by immunofluorescence flow cytometry for a panel of surface membrane markers, including IgM and IgD, the monoclonal antibodies anti-CD3, -5, -20, -21, -22, -FMC7, and, for the final 125 patients, anti-CD23. There were 503 CD5+ and 37 CD5- cases. In the CD5+ cases, the cells typically expressed IgM, IgD, CD20, CD21, CD22, and CD23. In univariate analysis, age, clinical stage, IgM-fluorescence intensity, CD23, and FMC7 had significant prognostic importance, with high IgM-fluorescence intensity, high FMC7, and low CD23 expression being associated with a short survival. There was no significant difference in survival between 351 cases expressing IgMD and 55 cases expressing IgM without IgD, or between kappa and lambda light chain monoclonal cases. CD20, CD21, and CD22 had no prognostic importance. In Cox multiple regression analyses, age, CD23, IgM-fluorescence intensity, and clinical stage (International Workshop System) had independent prognostic importance. Thus, besides clinical variables, CD23 and IgM intensity might be useful prognostic markers in the management of CD5+, B-cell CLL. The survival of CD5- patients was on the borderline of being significantly shorter than that of CD5+ patients. The majority of the CD5- cases were FMC7+, CD23-, had strong IgM fluorescence, and had splenomegaly.

Abstract
In a Danish population-based non-Hodgkin lymphoma (NHL) registry, 1257 newly diagnosed NHL cases were registered over a 5-year period. Of these, 463 (37%) were extranodal. The gastrointestinal tract was the most common site of extranodal involvement (30% of the cases). Histologically, 44% of all extranodal NHL cases had high-grade, 17% intermediate and 27% low-grade features, while 12% were unclassified. The most common histological subtype (Kiel) was the centroblastic diffuse (23% of cases). 50% of all extranodal NHL were localised (stage IE or IIE) and 27% had B symptoms. Site-specific features included a strong age-correlation for thyroid and testes lymphoma (greater than 50 years) and a high prevalence of female cases in thyroid and salivary glands lymphomas (M/F 0.14 and 0.30, respectively). Overall 7-year survival for extranodal NHL was 46% (median 4.9 years). Poor prognosis patients could be identified by the presence of one or more of the following presentation characteristics: age greater than 65 years, B symptoms, high-grade histology, disseminated disease, elevated s-IgA and hyperuricaemia. Relative risk values ranged from 2.1 for age and B symptoms to 1.7 for hyperuricaemia.

Abstract
The authors present the organisation and preliminary experience with a comprehensive autologous bone marrow transplantation (ABMT) program in patients with malignant blood diseases. The procedure involves harvesting of bone marrow from patients in complete remission, purification of mononuclear cells and cryopreservation of these at -196 degrees C. After bone marrow cultures show that a sufficient number of hemopoietic progenitor cells (CFU-GM) are present in the marrow to reconstitute the patient, he/she is conditioned with chemo- (busulphan/cyclophosphamide (Bu + Cy)) or chemo/radiotherapy (total body radiation/cyclophosphamide (TBI + Cy)) in doses equal to those commonly used in allogeneic BMT. From February 1988 to July 1990 bone marrow (BM) was harvested from 24 patients. The median yield of mononuclear cells (MNC) was 1.2 x 10(8)/kg body weight (range 0.55-3.7). After buffy coat preparation, density gradient centrifugation, cryopreservation and thawing out, 0.60 x 10(8) MNC/kg (0.18-3.3) corresponding to 9.3 x 10(4) CFU-GM/kg (2.28-144) could be recovered. Twelve patients have received transplants, five with AML (after Bu + Cy conditioning), six with lymphoblastic lymphoma and one with Hodgkin's disease (with TBI + Cy conditioning). The median number of days to obtain greater than 1.0 x 10(9) leucocytes/l, greater than 0.5 x 10(9) neutrophils/l, greater than 50 x 10(9) thrombocytes/l and last requirement for erythrocyte transfusion were 21 (12-49), 28 (10-60), 55 (21-270) and 55 (12-129) days, respectively. Four patients had sepsis and the median duration of hospitalization was 39 (22-58) days. The most severe complications were seen in the AML patients, two of whom died during the posttransplant period (one of septicemia, one of thrombocytopenic bleeding).(ABSTRACT TRUNCATED AT 250 WORDS)

Abstract
The trial included 85 previously untreated patients (median age 61 years) with stage III or IV non-Hodgkin's lymphoma (NHL) of the subtypes centrocytic lymphoma, diffuse centroblastic lymphoma, immunocytoma, immunoblastic lymphoma, or unclassified lymphoma of high grade malignancy. The patients were randomized to 9 monthly treatment cycles of CHOP (cyclophosphamide, doxorubicin, vincristine, prednisone) or CisEBP (cisplatin, bleomycin, etoposide, prednisone). Patients who had failed to achieve even a partial response (PR) after the completion of 2 cycles were switched to the alternative regimen. Complete response (CR) on primary treatment was obtained in 70% (55-83%) of CHOP-treated patients and in 25% (13-41%) of CisEBP-treated patients (p = 0.0004). Secondary CHOP treatment produced CR in 7 (30%) of 24 patients and secondary CisEBP treatment led to CR in 2 (15%) of 14 patients. The median survival was 3.4 years in the CHOP arm and 2.6 years in the CisEBP arm (p = 0.78). Hematologic toxicity was mainly leukocytopenia and anemia in both treatment arms. Non-hematological toxicity was slight, and late toxicity was insignificant. Three treatment-related deaths were noted. We conclude that CHOP induces more remissions than CisEBP in advanced lymphomas of high grade malignancy.

Abstract
A 53-year-old woman was treated for and cured of low grade malignant lymphoma, localized to the neck, by irradiation and chemotherapy. One year later she developed signs of damage to the spinal cord with slight paraparesis of the lower extremities, which remained stationary for seven years. Then, new and rapidly progressive central and peripheral neurological symptoms developed. About one year later the patient died. At autopsy a malignant glioma of the right temporal lobe and radiation damage to the spinal cord were found. Lymphocytic infiltrations in the peripheral nerves and muscles of the lower extremities were also seen. A severe neurogenic atrophy was present but no relapse of malignant lymphoma was found. Depressed immune defense is suggested to be the cause of the pathological changes of the nervous system in this case. The inflammation of the peripheral nerves might be due to activation of a latent virus infection.

Abstract
During a period of 17 months, 98 consecutive patients with malignant lymphoma were examined for initial staging before therapy. Both CT and lymphography were performed in 58 patients (19 patients with Hodgkin's disease (HD) and 39 patients with non-Hodgkin lymphoma (NHL], and these were included in the investigation. The results were discrepant in 26 cases where lymph node lesions were detected by only one of the two methods. In 10 patients, 5 with HD and 5 with NHL, the positive finding by one of the methods was taken as determinant of the stage. The conclusion drawn was that CT cannot completely replace lymphography without losing important information. Owing to limited resources for lymphography and CT a reduced staging programme is proposed. Judging by the present results, this reduced programme would probably mean only a minimal loss of information.

Abstract
After 2 years of maintained complete remission, a 17-year old girl suffering from common acute lymphoblastic leukaemia (C-ALL) developed a mass in the right breast. Determination of the tumour cell phenotype using a panel of monoclonal antibodies demonstrated the presence of leukaemic blasts. At this stage no other sign of relapse could be demonstrated. Later, however, when the leukaemia progressed despite aggressive treatment, blasts with the same surface phenotype as the ones in the breast were obtained both from repeated biopsies from a mediastinal mass and from a lower abdominal mass. Manifestation of first relapse in ALL presenting as a breast tumour has never been described before and may be added to other unusual extramedullary sites of relapse. The significance of immunologically defined phenotyping of cells from tissue biopsies is underlined.

Abstract
A retrospective analysis of 48 patients with primary, gastric lymphoma was performed. The clinical features, early symptoms and signs were found to be similar to cases of gastric carcinoma. Often surgery was necessary to confirm diagnosis. The treatment modalities surgery, radiation therapy and chemotherapy are discussed. The prognosis for this limited group of patients was a 5-year survival rate of 62 per cent, and a 10-year survival rate of 48 per cent (crude survival). Survival data from comparable series are presented.

Abstract
The otological manifestations of Wegener's granulomatosis were studied in 13 patients; diagnosis was confirmed histologically in 10, and in 1 patient periarteritis nodosa presented similar appearances. One patient had destruction of the external ear, and several had refractory otitis externa, usually associated with otitis media: 3 patients had serous otitis media, 4 had purulent otitis media of a fairly mild course, while 6 had otitis media of a fulminant and long-lasting course, accompanied in 5 cases by cranial nerve palsy and in 2 by widespread destruction. Most patients had major sensory hearing loss. Two had short-lasting anacusis during exacerbation of the pulmonary lesions. Often, otological manifestations were the initial signs of the disease. It is important to bear this diagnosis in mind in cases of long-lasting and atypical inflammations and in the presence of peculiar constellations of symptoms from several different organ systems.

Abstract
Seventeen patients with Wegener's granulomatosis are presented. The very complex clinical features are outlined. A recently suggested new classification (ELK-classification) is applied. Fourteen patients were treated with cytotoxic agents and steroids, 12 of these receiving 6-mercaptopurine. Of the ten patients still alive, eight are in remission with treatment withdrawn in three cases. The duration of the treatment is discussed. The results are largely satisfactory, but the course of the disease is still capricious. Progression to a higher step in the ELK-classification has been observed in several cases and a number of serious sequelae to the disease are recorded. The initial symptoms of Wegener's granulomatosis are varied and uncharacteristic, and it is important to bear this disease in mind when patients with a long course of apparently trivial infections or peculiar constellations of symptoms from several organs are encountered. Repeated biopsies from the respiratory tract are important in order to establish the diagnosis, but treatment should not be delayed in cases where only a tentative diagnosis can be made on the basis of a reasonably typical clinical picture, even with a negative histological response.

Abstract
A 6-year-old boy presenting with swelling of cervical and axillary lymph-nodes was diagnosed as having an Epstein-Barr virus infection because of EBV-nuclear-antigen-positive B-lymphocytes in blood and lymph nodes and high antibody titres to EBV antigens. The natural killer activity of blood-lymphocytes was low, and so was the percentage of T-lymphocytes with Fc receptors for IgG (T-gamma cells). Chromosomal studies revealed a defect in the long arms of one of the chromosomes in pair no. 16 (16q22). The defect only appeared after addition of interferon to the lymphocyte cultures and preferentially in T-gamma lymphocytes. The disease progressed despite attempts to restore the patient's immune reactivity by interferon, transfer factor, and blood transfusions. Necropsy showed that the severe hyperplasia of lymph nodes found during life had become a Burkitt-like lymphoma. The possible connection between an interferon-induced chromosomal defect (break at 16q22) and reduced level of natural killer activity, reduced T-gamma lymphocytes, and proliferation of EBV-positive B-lymphocytes is discussed.

Serum copper determinations were routinely performed in 141 men and 100 women with histologically verified Hodgkin's disease, admitted to the Radium Centre for Jutland over a 10-year-period from January 1, 1963, to January 1, 1973. The previously described variations in serum copper with the activity of the disease, increasing with progression and decreasing with improvement, were amply substantiated. Furthermore, the present study showed that the serum copper value at the first admission, before treatment, is statistically significantly correlated to the stage of the disease and consequently probably to the amount of tumor tissue. In men there was also a statistically significant correlation of se Cu to the histologic grade of the bioptic material (classification according to Lukes 1966). In women the correlation was blurred by the effect on serum copper of estrogen, mainly from contraceptive pills and pregnancy. The serum copper is regularly reduced to within normal limits at complete remission; thus, it is proposed that this parameter be included in the criteria for complete remission.
