In order to ascertain the frequency and distribution of isochromosomes in neoplasia, we surveyed the cytogenetic data from 20,007 tumors with clonal chromosome aberrations reported in the literature. Tumor types for which at least 50 cases with acquired aberrations and 10 cases with isochromosomes had been reported were selected, yielding a total of 18,160 neoplasms. Of these, 1,792 cases (9.9%) displayed a total of 2,014 isochromosomes. The 9 most common isochromosomes (detected in at least 50 cases) were, in decreasing order of frequency, i(17q), i(8q), i(1q), i(12p), i(6p), i(7q), i(9q), i(5p), and i(21q). The frequency of isochromosomes varied among the different tumor types, with the highest incidence in germ cell neoplasms (60%) and the lowest in chronic myeloproliferative disorders (2.3%). Also, the spectrum of isochromosomes differed among the neoplasms. The most common isochromosomes in the different tumor types were i(11q), i(17q), and i(21q) in acute myeloid leukemia; i(9q), i(17q), and i(22q) in chronic myeloid leukemia; i(17q) in chronic myeloproliferative disorders; i(X)(q13), i(17q), and i(21q) in myelodysplastic syndromes; i(7q), i(9q), and i(17q) in acute lymphoblastic leukemia; i(1q), i(7q), i(8q), and i(17q) in chronic lymphoproliferative disorders; i(1q), i(6p), i(9p), i(17q), and i(21q) in Hodgkin's disease; i(1q), i(6p), and i(17q) in non-Hodgkin's lymphoma; i(1q), i(8q), and i(17q) in adenocarcinoma; i(1q), i(3q), i(5p), and i(8q) in squamous cell carcinoma; i(5p), i(8q), and i(11q) in transitional cell carcinoma; i(1q), i(7q), and i(17q) in Wilms' tumor; i(1q), i(12p), and i(17q) in germ cell neoplasms; i(1p), i(1q), i(6p), and i(17q) in sarcoma; i(5p), i(6p), i(7p), and i(21q) in mesothelioma; i(1q), i(6p), and i(17q) in malignant neurogenic neoplasms; i(1q), i(6p), and i(17q) in retinoblastoma; and i(1q), i(6p), and i(8q) in malignant melanoma.

Twenty-eight patients with poor prognosis acute myeloid leukemia (AML) received therapy with two courses of fludarabine 30 mg/m2/day + ara-C 2 g/m2/day (days 1-5) and G-CSF 5 mg/kg/day (FLAG) (from day 0 to polymorphonuclear recovery). Eighteen patients were considered 'refractory' (eight primarily resistant, five relapsing within 6 months of initial remission, or at a second relapse; five relapsing after an autologous bone marrow transplantation procedure. Ten cases were defined 'secondary' AML (diagnosis of AML made after a preexisting diagnosis of: myelodysplastic syndrome: five cases; myelodysplastic syndrome after therapy for breast cancer: one case; previously untreated, and concomitant, non-Hodgkin's lymphoma: two cases; Hodgkin's disease treated with chemoradiotherapy: one case). Overall, 15 patients (58%) achieved a complete remission (CR). Two patients died of infection during induction, and 11 had resistant disease. Analyzing the data in relation to selected host and disease characteristics, the response varied widely. The highest CR rates (89%) were obtained in secondary AML; in particular, two cases of 'second-primary' (concomitant with low-grade non-Hodgkin's lymphoma) AML obtained CR for both diseases. Refractory AML differed widely for response: high CR rate (75%), although with short mean CR duration for primary resistance AML, and very poor response (11% CR) for relapsed (early, second, after ABMT) cases. Interestingly, a slow kinetic of leukemic growth in vivo before FLAG administration was significantly related to the response and outcome (p = 0.0002). Hematological and nonhematological toxicities were acceptable. In conclusion, the FLAG regimen has significant antileukemic activity and acceptable toxicity especially in secondary AML, both with and without coexisting lymphoid malignancy.

The clinical and microbiological features of 7 cases of bacteremia due to Capnocytophaga (Capnocytophaga ochracea group) are reported. They were diagnosed during 1991-93 at three hospital clinics. Five patients were < 10 years old and all had hematological disorders, 4 acute lymphoblastic leukemia and 1 each had aplastic anemia, non-Hodgkin lymphoma, and myelodysplastic syndrome. All were profoundly granulocytopenic with an absolute granulocyte count < 0.13 x 10(9)/l, and all but 1 had oral lesions as a possible portal of entry. A favourable response to antibiotic therapy was recorded in all patients but one who, being profoundly granulocytopenic, rapidly succumbed to Pseudomonas aeruginosa septicemia. None of the isolates were beta-lactamase producers. In addition to penicillin the isolates were susceptible to broad-spectrum cephalosporins and ciprofloxacin, but resistant to aminoglycosides.

The patients with a hematopoietic neoplasm can develop myelodysplastic syndrome following chemotherapy. We report herein a case of non-Hodgkin B-cell lymphoma and refractory anemia with ringed sideroblasts. Absence of the preceding chemotherapy establishes the true coincidence of the two disorders. We review 25 similar cases reported in the last 11 years and discuss the possible etiology of coexistence.

Granulocytic sarcoma (GS) is a solid tumor of extramedullary localization constituted by immature precursors from the granulocytic series. GS may be diagnosed in different malignant blood diseases involving the granulocytic series, acute non lymphoblastic leukemia (ANLL) being the most frequent, followed by myelodysplastic syndromes (MDS) and chronic myeloproliferative syndromes, specially chronic myeloid leukemia (CML) in blastic crisis. Although the diagnosis of GS is suspected with conventional cytologic and anatomopathologic studies, histochemical staining and immunohistochemical techniques are often required for definitive diagnosis. Five cases (4 males, 1 female; age range 22-77 years) diagnosed with GS in one center over a period of nine years (1984-1993) are described. The GS were located in the lymph nodes, the jaw, paravertebral region, gallbladder and retroperitoneum, respectively. Two patients had refractory anemia with excess of blasts (RAEB). Three patients had ANLL; in one GS constituted the form of relapse, in another GS presented at the time of diagnosis and in the remaining patient GS preceded the diagnosis of ANLL. All the patients died from 2 to 8 months after diagnosis of GS with no response to treatment being observed. Immunohistochemical study of the tumor was performed in 4 patients, being positive for lysozyme and the monocytic MAC-387 monoclonal antibody. Immunocytochemical study of the tumor blasts was carried out with positivity for CD15 being observed. Although uncommon, GS should be suspected in patients with ANLL or MDS with tumors of any localization and at any time during its evolution. Immunocytochemical and immunohistochemical studies are of great value to differentiate GS from other tumors, particularly anaplastic non Hodgkin's lymphomas.

Eight-five consecutive patients with relapsed or refractory Hodgkin's disease (HD) underwent high-dose chemotherapy or chemo/radiotherapy followed by autologous bone marrow (ABMT) and/or peripheral blood stem cell (PBSC) transplantation. Two preparative regimens were used. Twenty-two patients (26%) without prior radiation received fractionated total body irradiation (FTBI) 1,200 Gy in combination with high-dose etoposide (VP-16) 60 mg/kg and cyclophosphamide (CTX) 100 mg/kg. Sixty-three patients (74%) with prior radiotherapy received carmustine (BCNU) 450 mg/m2 instead of FTBI. The median age was 32 years (range, 16 to 56). The median number of prior chemotherapy regimens was three (range, 1 to 7). Forty-three patients (51%) received transplants in first relapse or second complete remission (CR), whereas 33 (39%) received transplants after second or subsequent relapse. All relapsed patients, except one, received conventional salvage chemotherapy and/or radiotherapy in an attempt to reduce tumor bulk before transplant. At the time of analysis in April 1994, fifty-seven patients (67%) are alive, including 44 (52%) in continuous CR, with a median follow-up for the surviving patients of 28 months (range, 7 to 66). Thirty patients (35%) relapsed at a median of 9 months (range, 1 to 43). Eleven patients (13%) died of transplant-related complications including veno-occlusive disease of the liver (VOD) in five, acute and late interstitial pneumonitis in three, graft failure in one, cerebral hemorrhage in one, and therapy-induced myelodysplasia (MDS)/acute leukemia in one patient. At a median follow-up of 25 months (range, 0.6 to 66), the cumulative probability of 2-year overall and disease-free survival (DFS) of all 85 patients is 75% (95% confidence interval [CI] 64% to 84%) and 58% (95% CI 47% to 69%), respectively. Three independent prognostic variables were identified by univariate analysis: number of prior chemotherapy regimens, prior radiotherapy, and extranodal disease at ABMT. Multivariate stepwise Cox regression identified the number of prior chemotherapy regimens as the only significant prognostic factor predicting for both relapse and DFS. There were no significant differences in the outcome of the treatment between the two preparative regimens. Our results confirm that high-dose therapy and ABMT is an effective therapy for patients with relapsed or refractory HD. Earlier transplantation is recommended before the development of drug resistance and end organ damage that results from repeated attempts of salvage therapy.

Patients who have recovered from malignant lymphoma are at an increased risk of secondary acute leukemia (AL), and overt AL is frequently preceded by a myelodysplastic syndrome. Although the statistical risk is significant, only a minority of the patients will be so affected. We have reviewed peripheral blood counts of patients with Hodgkin's disease (HD) and non-Hodgkin's lymphoma (NHL) treated in the Departments of Hematology at the Edith Wolfson and Chaim Sheba Medical Centers, Israel. Included were only those who went into a complete remission and remained lymphoma free for extended periods. There were 85 patients with HD and 36 with NHL. In both groups peripheral blood counts at diagnosis were within the normal range. A prolonged follow-up (> 4 y), during which no further treatment was given, revealed a sustained increment over time of MCV (delta MCV) both in HD and NHL. A persistent monocytosis in HD patients was also evident. delta MCV was larger in HD. The difference at the end of the follow-up period was as follows: 10.1 fl + 11.8 in HD vs 5.0 fl + 6.2 in NHL, (P < 0.001). In addition, a significant loss of the normal correlation between the MCV and levels of hemoglobin was seen at the last follow-up. The change in MCV was present in all treatment groups, its magnitude increasing from radiotherapy to chemotherapy to combined radio chemotherapy. This trend is in analogy to the risk of secondary AL which is lower in NHL vs HD. Furthermore, it is lowest post radiotherapy and highest when both treatment modalities are used.(ABSTRACT TRUNCATED AT 250 WORDS)

After previous serological screening for Epstein-Barr virus (EBV), human herpesvirus-6 (HHV-6) and human cytomegalovirus (HCMV) showed elevated antibody titers against EBV and HHV-6 in more than 50% of patients with myelodysplasia and chronic myeloproliferative diseases, the present study was carried out in order to investigate viral antigen expression and distribution in bone marrow cells of these patients. Trephine biopsies were studied from 60 patients with myelodysplasia (MDS), 36 patients with chronic myelogenous leukemia (CML) and 18 patients with osteomyelofibrosis (PMF). Elevated anti-EBV EA titers were found in 62% of the MDS cases, in 33% of the CMLs and in 62% of the OMF patients. HHV-6 titers were elevated in 18% of the MDS cases, but in only one case each of CML and OMF. Antigen expression in bone marrow cells was even more frequent: EBV-EA was 76% in MDS cases, 77% in CML and 40% in OMF. HHV-6 p41 was observed in 47% of the MDS cases, in 54% of the CML cases and in 20% of the OMFs. In comparing these data with those from the literature and with our own studies in Hodgkin's disease, it is hypothesized that the reactivated herpesviruses may contribute to the pathogenesis of these hematopoietic disorders by interfering with the cytokine regulation of cell proliferation and differentiation.

A patient with refractory relapsed Hodgkin's disease underwent an autologous bone marrow transplant in July 1987 and achieved remission of Hodgkin's disease. He had complete hematological recovery but developed pancytopenia 3 years post bone marrow transplantation with morphological evidence of myelodysplasia. High-dose cyclophosphamide, 200 mg/kg, chemotherapy followed by an allogeneic bone marrow transplant from a HLA-matched sibling was performed in April 1991 with complete hematological recovery. Allogeneic bone marrow transplantation was thus used successfully to treat a potential complication of autologous bone marrow transplantation.

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.
