Abstract
The aim of the present study was to examine caspases, granzyme B and bcl-2 family mRNA expression and the degree of apoptosis in the bone marrow (BM) of 46 Myelodysplastic Syndromes (MDS) and to correlate our findings with clinical parameters. The degree of apoptosis was determined by Annexin V, whereas expression of genes was determined using a multiprobe RNase Protection System. A positive correlation was found between caspases 8, 5, 3, 2, 1 and the level of apoptosis. bfl1 and mcl1 levels were significantly higher in patients with BM blasts >5%. Cases with ratio of bid expression >1 compared to normal pool were associated with IPSS values < or =1.

Abstract
P27 encodes a member of Cip/Kip family of cyclin dependent kinase inhibitors, the inactivation of which has been implicated in the pathogenesis of various hematological neoplasias. We report on a novel point mutation of this gene identified in a case of unclassified myeloproliferative syndrome consisting of a T --> C transversion at 821bp of p27 exon 1, resulting in a Ile --> Thr substitution at codon 119. The analysis of larger number of cases as well as the effect of this mutation on protein's function will help to clarify its significance in the pathogenesis of myeloproliferative syndromes.

Abstract
The Mixed Lineage Leukemia (MLL) gene has been identified in 11q23 translocations. The aim of the present study is the investigation of the frequency of MLL gene rearrangements in cases of de novo myelodysplastic syndromes (MDS). Sixty-two patients with de novo MDS were included in the analysis. The detection of MLL gene rearrangements was performed by Southern blot. Clonal karyotypic abnormalities were found in 15/50 (30%) cases. 11q23 abnormalities were not detected. One case with RAEB and a complex karyotype presented a del (11)(q13); further analysis by FISH revealed loss of one copy of MLL gene in all metaphases. Southern blot revealed germline bands in all cases using Eco RI and in 61/62 cases with Bam HI. The case with RAEB and a del (11)(q13) revealed a rearranged band following only Bam HI digestion, but not Eco RI. Rearrangements of MLL gene within exons 5-9 were not identified in this series of adult de novo MDS, indicating that this molecular abnormality is not involved in the pathogenesis of this group of hemopoietic disorders.

Abstract
The purpose of this prospective phase II trial was to investigate the safety and efficacy of a modified baseline BEACOPP (bleomycin, etoposide, adriamycin, cyclophosphamide, vincristine, procarbazine, and prednisone) regimen in the treatment of intermediate and advanced stage Hodgkin's disease (HD). From October 1997 to November 2001, 51 consecutive, previously untreated patients with stage IIA (bulky), IIB, III, and IV disease were treated with a modified baseline BEACOPP regimen with the etoposide administered i.v. on day 1 and orally at a dose of 100 mg/m2, on days 2 and 3. Each patient was scheduled to receive eight courses of BEACOPP with consolidation radiotherapy to bulky (> or =5 cm) or residual disease. There were 25 males and 26 females with a median age of 32 yr (16-65 yr); 80.3% of the patients had nodular sclerosis HD, 41% had bulky disease (> or =5 cm), 10 were in stage IIA (bulky > or =10 cm), 15 in stage IIB, 19 in stage III, and seven in stage IV. Thirty-seven patients (72.5%) achieved a complete response and 17.6% partial response. No significant difference in overall response rate was observed between patients with: (i) 0-2 vs. > or =3 negative prognostic factors, (ii) in stage II vs. stages III/IV, LDH level, and bulky disease. With a median follow up period of 39.5 months, actuarial 3-yr survival rate is 82% and time to progression rate 72.5%. Treatment with this combination was well tolerated. Grades 3 and 4 leukopenia and neutropenia occured in 26% and 28% of the patients, respectively, whereas in 16.3% of the patients infection was observed. Support with granulocyte colony-stimulating factor was given to 59% of the patients. No case of secondary MDS/leukemia has been observed. The results of the present study demonstrate that the modified baseline BEACOPP regimen with radiotherapy used in our patients was well tolerated and effective therapy for intermediate and advanced stage HD. Further follow up time is required to evaluate long-term toxicity.

Abstract
The association of monoclonal gammopathy (MG) with B-cell non-Hodgkin's lymphomas (NHL) is a well known phenomenon. The aim of the present work was to study the incidence, type of monoclonal component and prognostic significance of MG in a population of 255 cases with B-cell NHL. Among 255 evaluable patients with B-cell NHL, 145 were males and 110 females with a median age of 58 years (range 18-85). There were 166 patients with the various subtypes of aggressive (intermediate/high grade) NHL and 89 with the various subtypes of low risk. MG was detected in 44 patients (17.2%) with a median age of 61 years (range 23-79). There were 22 cases (8.6%) with IgG type (IgG/(k) 15, IgG/(lambda) 7), 4 cases (1.6%) with (IgA/(k) 3, IgA/(lambda) 1) and 18 cases (7.0%) with IgM (IgM/(k) 12 IgM/(lambda) 6). MG was found in 15.6% of the patients with aggressive NHL, while in low risk NHL the incidence was 20.2% (N.S.). The type of MG according to histological classification was as follows: Aggressive NHL: IgG 17 cases, IgA 2 cases, IgM 7 cases: low risk NHL: IgG 5 cases, IgA 2 cases, IgM 11 cases. The distribution of MG according to stage of the disease was as follows: stage I (4.5%), stage II (18%), stage III (6.8%) and stage IV (70.4%). The median survival of patients with aggressive NHL with MG was 17 months compared to 40 months of those without (P=0.22). Similarly the median survival of patients with low risk NHL and MG was 51.5 months compared to 38.5 months of those without (P=0.90). In conclusion MG was detected in 17.2% of cases with B-cell NHL. IgG-MG was more frequent in cases with aggressive NHL, while IgM in cases with low risk NHL. MG was mostly associated with advanced stage and had not any prognostic significance on survival.

Abstract
OBJECTIVES Clinical features, response to treatment and survival of T-cell-rich B-cell lymphoma (TCRBCL) patients were compared to those of a similar group of patients with diffuse large B-cell lymphoma (DLBCL). METHODS Between 1992 and 1999, 10 patients with a diagnosis of TCRBCL were treated in our department. Over the same 7-year period, a group of 65 patients with DLBCL were diagnosed in the same department. Both groups of patients were treated with the same anthracycline-based chemotherapy. RESULTS A significantly higher percentage of patients with TCRBCL presented with B-symptoms, elevated LDH, bone marrow infiltration and disseminated extranodal involvement compared to patients with DLBCL. TCRBCL patients responded poorly to combination chemotherapy, since only 3 of them achieved complete remission (33%) compared to 48 (75%) patients with DLBCL. All patients with TCRBCL who achieved complete response relapsed within the first 2 years while 65% of patients with DLBCL survive disease free for a median follow-up period of 4 years. The median overall survival for DLBCL patients has not been reached yet, while it was 18 months for TCRBCL patients. CONCLUSIONS Although the number of patients in our study is small, it seems that patients with TCRBCL present with advanced disease, respond poorly to chemotherapy and display a short disease-free and overall survival compared to patients with DLBCL.

Abstract
Thrombotic thrombocytopaenic purpura (TTP) is characterised by platelet aggregation in the capillaries, thrombocytopaenia and microangiopathic haemolytic anaemia that result in organ ischaemia, mainly of the CNS and kidneys. Since the institution of plasma exchange therapy no further treatments have been proved to improve the survival and the relapse rate of TTP patients. In this retrospective study, we evaluated the efficacy of normal human immunoglobulin treatment in 44 patients suffering from TTP. Patients were divided into two groups that either did not receive (group A: 15 patients) or received (group B: 29 patients) 400 mg/kg of human normal immunoglobulin intravenously (ivIgG) for 5 days. All patients received treatment with corticosteroids, anti-platelet agents and plasma exchange. The results clearly showed that there was no statistically significant difference between the two groups in either remission rate or time to relapse following remission. In conclusion, this study did not prove any beneficial effect of ivIgG in the treatment of TTP patients.

Abstract
Splenectomy in patients with non-Hodgkin's lymphoma (NHL) is performed for either diagnostic or therapeutic reasons. We report on a series of 29 patients with NHL and splenomegaly who underwent splenectomy during the years 1979-1998 in our hospital. According to the indication for splenectomy our patients were categorized in three groups. Group A: In 20 patients splenectomy was performed for diagnostic reasons. Group B: Three patients were splenectomized for autoimmune haemolytic anaemia (AIHA). Group C: Six patients underwent splenectomy because of hypersplenism. A definitive histopathological diagnosis of NHL was obtained in all patients of group A. Hypersplenism and AIHA were resolved in all patients after splenectomy. One (3.5%) patient died postoperatively because of septicemia complicated by disseminated intravascular coagulation. Six postoperative complications were observed in 4 (14%) patients. Splenectomy, with an acceptable surgical risk, has the potential to establish the diagnosis of NHL in patients with splenomegaly without lymphadenopathy and negative bone marrow findings. Moreover, splenectomy has the capacity to modify the disease course in patients with NHL complicated by AIHA or hypersplenism.

Abstract
The thrombotic thrombocytopenic purpura/ hemolytic uremic syndrome (TTP/HUS) is a rare disorder characterized by microangiopathic hemolysis and thrombocytopenia. We have undertaken a retrospective analysis of the clinical characteristics, treatment outcome, and prognosis of 48 patients diagnosed and treated in our institution during a 13-year period. Among our patients 22 (46%) had fever, 35 (73%) neurological abnormalities, and 22 (46%) renal impairment at presentation of the syndrome. All patients were treated with a multimodality regimen including plasma exchange, steroids, antiplatelet agents, and IgG infusion. Of the 48 patients, 41 achieved complete remission, two had a partial response, and five had no response and died of progressive disease. Within a median follow-up period of 40 months, ten of the 41 patients who had achieved remission relapsed, most of them within the first 2 years, and nine of these responded promptly to plasma exchange therapy. Eight deaths were observed, seven of refractory disease and one in fourth relapse. The analysis of prognostic factors revealed advanced age and severe renal impairment (creatinine levels above 2 mg%) as the only parameters associated with treatment failure and poor outcome. However, none of the pretreatment characteristics proved to be of prognostic value regarding the probability of relapse. In conclusion, TTP/HUS represent a syndrome of variable clinical expression and aggressiveness. The use of a multimodality regimen in our series produced a high response rate. Nevertheless, the early identification, based on clinical characteristics, of poor-prognosis cases that probably need more or alternative forms of treatment is an issue that remains to be elucidated in prospective trials.

Abstract
Primary extranodal NHL of the head and neck (HN-NHL) accounts for 10-20% of all cases of NHL. Despite their frequency, the natural history and biological behaviour of these lymphomas is poorly understood. In this study we analysed the data 116 cases of HN-NHL. There were 65 males and 51 females with a median age of 56 years. The distribution among different anatomical sites was: tonsils 56 cases (48.3%), nasopharynx 15 (12.9%), mandible/gingiva 9 (7.8%), hard palate 7 (6%), parotis 6 (5.2%), nasal cavity 6 (5.2%), hypopharynx/larynx 6 (5.2%), thyroid 5 (4.3%), ocular adnexa 4 (3.5%), paranasal sinuses 2 (1.7%). The patients were treated with radiotherapy alone (14 cases), combined chemotherapy (52 cases) and combined modality (50 cases). According to the WF histological classification 73 cases (62.9%) had intermediate, 32 (27.6%) high and 11 (9.5%) low grade. Patients were separated in two groups: Tonsillar NHL (56 cases) and NHL of all other sites (non-tonsillar group-60 cases). A comparison between the two groups showed that there was no statistically significant difference with respect to age, sex, and histological subtypes. Also treatment response was similar (82.1% for the tonsillar vs 83.3% for the non-tonsillar). The two groups differed in stage distribution, survival and pattern of relapse. Stage I was more frequent in the non-tonsillar NHL (60%) in contrast to tonsillar NHL where stage II was more prominent (51.8%). Median survival was 86 months for the tonsillar while it has not been reached yet for the non-tonsillar patients. Patients in stage I and stage II of the non-tonsillar group had better survival compared to stages I and II of the tonsillar patients. Finally GI tract was a common site of relapse in the tonsillar group while a considerable number in CNS relapses were observed in the non-tonsillar group. We concluded that HN-NHL constitutes a heterogeneous group of patients. Tonsillar lymphomas represent a distinct group with some special clinicopathological findings.

Abstract
In this prospective study, patients with "high risk' primary MDS, namely RAEB or RAEBt, were treated with combination chemotherapy (CT) supported by GM-CSF. The induction CT consisted of idarubicin 6 mg/m2 days 1-3 and cytosine-arabinoside 200 mg/m2 in 12 h infusion, days 1-5. The GM-CSF 3 micrograms/kg s.c. was given on day 6 until the neutrophil count was 1 x 10(9)/l. Postremission CT consisted of two similar courses. Patients not in remission after two courses of CT were considered as treatment failures. Twenty-two patients with a median age of 64 years, range 50-79 years (11 RAEB and 11 RAEBt) were evaluable. Twelve out of 22 patients (54.5%) achieved complete remission (CR) and four, partial remission. Six patients were resistant to treatment; there were two toxic deaths; seven patients achieved CR after the first course and five after two courses. The median time of neutrophil recovery to 1 x 10(9)/l was day 15 (range 3-22) after the first course of treatment and day 14 (range 4-21) after the second. Thirteen out of 22 patients developed febrile episodes after the first course of treatment and nine after the second. The median duration of CR was 12 months. The median survival for CR patients was 24 months, for non-CR patients, 12 months; while survival for the whole population was 18 months. In conclusion, the results of this study indicate that the administration of moderately intensive CT supported by GM-CSF in "poor risk' MDS gives promising results; the response rate is high for this disease, while the incidence of toxic death is low. GM-CSF appears to accelerate neutrophil recovery and probably reduces the incidence of infection.

Abstract
Among 318 cases of non-Hodgkin's lymphoma (NHL) treated in our unit, 145 (45.6%) had primary extranodal NHL (PE-NHL). The stomach was the most common site (42.1%), followed by the PE-NHL of the head and neck region. Histologically aggressive histologies (65.5% intermediate and 20.7% high grade) predominated. 89.6% of the cases were localized (stage IE, 51% and stage II, 38.6%) but 28% had B symptoms. CR was achieved in 82.1% of the cases. 5-years disease free survival and overall survival were both 65%. Factors that influence prognosis were stage and high grade histology. Among various primary sites the Waldeyer's ring, small intestine and testes had the worse prognosis. Compared to nodal NHL, the PE-NHL were more frequently localized, belonged more often to aggressive histologies and had more often distal extranodal relapses. CR rates and disease free and overall survival were significantly better for PE-NHL. The survival rates, however, listed according to stage and histology for nodal and PE-NHL were not different. We conclude that although PE-NHL differed from nodal NHL in several respects, prognosis is mainly a factor of stage and histology rather than of the primary localization per se.

Abstract
The risk and the type of second malignancies (SM) developing in 217 treated Hodgkin's disease (HD) patients were studied. The median age of the patients was 35 years (range 14-83) and the M/F ratio 1.8. Treatment consisted of radiotherapy alone (24 patients, 11%), chemotherapy alone (96 patients, 44.3%), or a combination of both modalities (43 patients, 19.8%), while 54 patients (24.9%) received salvage treatment. The median follow-up time was 67 months (range 12-224). Ten patients developed a SM with a 5-year and 10-year actuarial risk of 3.3% and 5.4%, respectively. There were 3 cases of ANLL and MDS (actuarial risk of 2.4% at 6 years), 1 case of non-Hodgkin's lymphoma and 6 cases of solid tumors (actuarial risk of 2.4% at 6 years). The risk of developing SM was higher in males and older patients (> 40 years). SM represent a serious late side effect of successful treatment for HD. The possibility of developing a SM must be taken into consideration in the initial treatment of the disease.

Abstract
Thirteen patients with thrombotic thrombocytopenic purpura were treated at our facility between 1985 and 1991. All patients were treated with plasma therapy (both plasma exchange and plasma infusions), prednisone, intravenous immunoglobulin, and antiplatelet agents. Twelve patients achieved remission (92.3%). One patient died from cerebral hemorrhage. Vincristine was administered to 5 patients who did not respond after the first two plasmaphereses. Splenectomy was performed in a patient who relapsed four times within a 2-year period. From the 12 patients achieving remission, 11 have been still in remission for a period of 3 to 69 months.

Abstract
In a phase II study, 21 patients with MDS (RAEB, RAEBt, CMML and RA and RAS with severe cytopenia) were randomized to be treated with 3 courses of GM-CSF (3 micrograms/kg/day s.c.) alone (11 patients) or in combination with AraC (20 mg/m2/d s.c.) (10 patients) for 14-d periods, interrupted by 14-d rest periods. Eight patients discontinued the treatment. In the GM-CSF group a marked increase in WBC and neutrophil counts during each course of treatment administration were seen in most patients. Platelet counts decreased in 14 of 24 courses of treatment in the GM-CSF plus AraC group but in none of the GM-CSF group. Although the changes in the circulating blood cells were transient and the counts tended to return to the pretreatment levels during the rest periods, some more durable effects were seen. In 3/6 patients of the GM-CSF group who completed the designed treatment, both WBC and neutrophils remained elevated above the pretreatment levels throughout the 3-month period of treatment, while in one of them thrombocytopenia improved considerably. In the GM-CSF plus AraC group, 4 out of the 7 patients who completed the treatment showed an improvement of neutropenia as well as anaemia. In these 4 patients the BM percentage of blasts was also decreased. In conclusion, the results of this study indicate that GM-CSF given intermittently improves leukopenia in some patients with MDS. In addition, the administration of GM-CSF seems to prevent granulocytopenia of concurrent AraC treatment and may be of benefit in the treatment of these diseases.

Abstract
Among 387 cases of non-Hodgkin's lymphoma (NHL) treated in our units between January 1977 and December 1990, 52 (13.4%) had primary extranodal (PE) NHL of the head and neck. The median age was 55 years with a M:F ratio of 1.9:1. The most frequent primary site was the tonsil (28 cases), followed by oral cavity, parotid gland, orbit and other sites. The aggressive histological subtypes predominate. 55.2% of the patients were in stage I and 44.8% in stage II of disease. The CR rate was high (94.2%). The 5 years' overall survival rate was 65% and it was influenced mainly by stage (stage I 82.5% vs. 48.7% in stage II). Sex, age and histology did not significantly affect survival rate. Patients with primary Waldeyer's ring involvement (WR group) did not differ significantly from the other primary sites analyzed as a group (non-WR group) in respect to median age, sex distribution, histology and CR rates. They differed, however, in: (1) stage distribution with stage II disease more frequent in the WR group; (2) overall survival and disease-free survival both of which were significantly better in the non-WR group; and (3) the high incidence of GI tract involvement as initial manifestation of relapse in the WR group. It is concluded that the behaviour of the Waldeyer's ring PE-NHL is rather distinctive and should be considered separately from the other PE-NHL of the head and neck.

Abstract
We report 2 of 80 cases of myelodysplastic syndromes (MDS) cytogenetically studied, with involvement of chromosome 13. The first case had a t(6;13), and the second had a t(1;13). Abnormalities of chromosome 13 mainly involving loss of band 13q14 have been described in hematologic malignancies. In both our cases band 13q14 did not participate in the deleted segment.

Abstract
BACKGROUND The development of acute non-lymphoblastic leukaemia (ANLL) or myelodysplastic syndromes (MDS) secondary to treatment of multiple myeloma (MM) is well known. In some cases the simultaneous appearance of MM and ANLL has been described. METHODS In this series the simultaneous appearance of MM and various myelopathies in 91 untreated patients with MM, and the development of myelopathies during the course of the disease in 72 treated patients were studied. RESULTS Simultaneous appearance of MM (IgA/lambda) and refractory anaemia with ring sideroblasts (RAS) was observed in one case (1.1%). Development of myelopathies in treated patients with MM was found in 4 out of 72 cases (cumulative risk at 8 years 28.3%). In one case (IgG/lambda MM) a myeloproliferative disorder (MPD) developed 6 years after the initial diagnosis. Cytogenetic analysis was normal. In the second patient (IgG/k MM) a similar MPD was observed 5 years after the initial diagnosis. The karyotype was 46, XX, -5 + t (20;?). The third patient with lambda light chain disease developed RAS 11 months after the initial diagnosis. The karyotype was 46, XY/hypodiploidy + M. Finally, the fourth case (IgG/k MM) developed ANLL (M4) 28 months after the initial diagnosis and the karyotype was 45, XX, -7, t(1;3). CONCLUSIONS The simultaneous appearance of MM and various myelopathies is unusual and probably represents a neoplastic transformation of a single progenitor in both lymphoid and myeloid malignancies. On the contrary, the development of myelopathies during the course of treated patients is a common phenomenon. The time of development and the cytogenetic findings strongly suggest that they are related to treatment with cytostatics.

Abstract
The incidence of monoclonal gammopathy in 61 patients with chronic myeloproliferative disorders (CMPD) was studied. The distribution of patients among the CMPD subgroups was: chronic myelocytic leukemia, 24 patients; myelofibrosis, 11; polycythemia vera, 15; essential thrombocythemia, 7; unclassified MPD, 4 patients. Monoclonal gammopathy was found in 5 patients (8.2%). Two of these patients (1 IgA/k and 1 IgM/k) had myelofibrosis and 3 (2 IgG/k and 1 IgG/lambda) polycythemia vera. The presence of monoclonal gammopathy indicates an involvement of the lymphoplasmatic system in CMPD.

Abstract
The clinical and haematological findings in 131 patients with myelodysplastic syndromes (MDS), none of which had previously received chemotherapy or radiotherapy, classified according to the FAB criteria, were analysed. The distribution among the 5 subgroups was: RA 31 patients, RAS 19, RAEB 23, CMML 29 and RAEBT 29 patients. There were difficulties in the classification of 24 patients. These included, first, 8 cases with myeloid hyperplasia of the bone marrow (BM) but without monocytosis or excess of blasts of the BM. They were classified as RA. Second, 8 cases with sideroblastosis but with monocytosis or excess of blasts of the BM were classified 3 as RAEB, 2 as CMML and 3 as RAEBT. Finally, 8 cases with absolute monocytosis and BM blasts 15-30% were classified as CMML. 37 of 82 dead patients (45.1%) had transformed to acute non-lymphoblastic leukaemia (ANLL). The incidence of evolution to ANLL was low for RA and RAS (6.30% and 12.5% respectively), while it was 37.5% for RAEB, 57.1% for CMML and 77.2% for RAEBT. The median survival for each subgroup was: RA 18 months; RAS 25; RAEB 13; CMML 14 and RAEBT 10 months. It is concluded that the FAB classification with some modifications recognises group of MDS with different prognosis.

Abstract
Lymphoproliferative syndrome with well differentiated lymphocytes and moderate lymphocytosis in the peripheral blood includes a heterogeneous group of disorders, that present often difficulties in classification. We have studied the lymphocyte markers (ER, EMR, sIg and T3, T4, T8 antigens) in 36 cases who had lymphocytic infiltration in the bone marrow and peripheral lymphocyte counts less than 15 X 10(9) l-1. Four cases (11.1%) had the characteristics of T8 lymphocytosis and 31 had a B cell monoclonal proliferation in the peripheral blood. Of these, four were sIg-, EMR+, 19 were sIg+, EMR+ and 8 were sIg+, EMR-. Most patients (17/32) had the clinical picture of stage 0 and I B-CLL. Six cases presented as pure splenomegalic form of CLL, three had the features of immunocytic lymphoma and five had the features of lymphocytic lymphoma. It is concluded that the majority of lymphoproliferative disorders presenting with moderate lymphocytosis represent early forms of B-CLL. Occasionally cases of lymphocytic or immunocytic lymphoma may present problems of differential diagnosis since there may be a dissociation of phenotypic characteristics of lymphocytes between tissues and peripheral blood.

Abstract
We analysed 29 consecutive cases of primary gastric lymphoma (20 men and 9 women) treated in our unit between January 1977 and May 1983. Median age was 55 years. Abdominal pain and weight loss were the main presenting symptoms while there was no palpable disease in the majority of cases. Upper gastrointestinal radiology was abnormal, but not diagnostic, in all cases. Endoscopy with multiple biopsies was performed in 22 cases; carcinoma was diagnosed in 11, lymphoma in 8 while no diagnosis was made in 3 cases. Twenty six patients underwent laparotomy. Gastrectomy was performed in twenty while the tumour was unresectable in six. Histology was reported as diffuse in 28 cases (16 histiocytic, 8 lymphocytic and 4 mixed) and nodular (lymphocytic) in one. All our patients received multichemotherapy. Complete remission after 6 courses was documented in 18 patients (62%). Neither perforation nor gastrointestinal bleeding was a problem in our series. Eighty four per cent complete responders are predicted to be alive at 4 years. Advanced stage (II2B and IV) and tumour size greater than 10 cm adversely influenced survival. We suggest that in limited primary gastric lymphoma an attempt at 'curative' surgery combined with multichemotherapy currently gives very promising results.

Abstract
The immune states of 52 patients with myelodysplastic syndromes classified according to the FAB criteria were studied. Serum electrophoresis and immunoelectrophoresis, direct Coombs test, and tests for organ and non-organ specific antibodies were performed. Twenty six patients had immunoglobulin abnormalities: six (11.5%) had monoclonal gammopathy; 17 (32.6%) had polyclonal increases in serum immunoglobulin; while in three (5.8%) immunoglobulin concentrations were decreased. The distribution of immunoglobulin abnormalities among the five myelodysplastic syndrome subtypes was fairly uniform. Results of direct Coombs test were negative in all cases. Organ specific antibodies were not detected in any of the patients tested, although two patients were found positive for antinuclear antibodies. The presence of immunoglobulin abnormalities indicates an involvement of the lymphoplasmatic system in myelodysplastic syndromes.

Abstract
A case of malignant lymphoma with a partial duplication of the long arm of chromosome #1, as well as 14q+ and 11q+ marker chromosomes, is presented. The coincidence of this duplicated segment of chromosome #1 with others described in the literature supports the idea that this specific chromosome segment may be related to the malignant process.

Abstract
A female patient, aged 44, with diabetes insipidus as a complication of acute myelomonocytic leukaemia (AMML) is described. She presented with bleeding, anaemia, polyuria and polydypsia. She was treated with intranasal vasopressin for diabetes insipidus and responded well to treatment. Chemotherapy was administered for the leukaemia and a full remission was achieved. The patient relapsed a few days before final admission to hospital and died of septicaemia 7 months after initial diagnosis. A short review of the literature related to this subject is also presented.

Abstract
In a retrospective study 37 patient who fitted into the clinical spectrum of myelodysplastic syndrome were reviewed. Special attention was paid to the influence of monocyte count, degree of blastic infiltration and ring sideroblasts and on the clinical presentation and the course of the disease. Monocyte count clearly distinguishes between two groups of patients with different haematological profile and clinical course. The patients with monocytosis frequently changed to acute myeloid leukaemia and had shorter survival rates compared with those without monocytosis. The degree of blastic infiltration does not affect the haematological presentation and the frequency of acute leukaemia evolution. However, increased blastic infiltration is associated with shorter survival. Patients with ringed sideroblasts presented with profound anaemia but the clinical course of the disease did not differ from the remainder.
