Seven cases of acute nonlymphocytic leukemia (ANLL) and one of malignant myeloproliferative syndrome were identified from a pool of 189 cases of non-Hodgkin's lymphoma (NHL) and CLL treated primarily with extensive radiotherapy at the Clinical Center, the National Institutes of Health. Four patients also received chemotherapy, two for only short periods. The median time interval from the diagnosis of the primary malignancy to the development of leukemia was 61 months (range 33 to 98 months) and the median survival after the diagnosis of leukemia was two months (0 to 9 months). All eight patients were cytogenetically abnormal and serial chromosome studies revealed that hypodiploidy was the most commonly observed chromosomal abnormality. Abnormalities of chromosome no. 7 were seen in all five patients analyzed by the chromosome banding technique; four of them had monosomy 7. The next most frequently involved chromosome was no. 5. The complexity, extensive nature, and long duration of the cytogenetic abnormalities prior to the diagnosis of leukemia in these patients may be characteristic of secondary leukemia in radiation-treated lymphoma and the presence of such anomalies may predict leukemic transformation.

Seven cases of acute nonlymphocytic leukemia (ANLL) and one case of a malignant myeloproliferative syndrome have been seen after extensive radiation therapy for non-Hodgkin's lymphoma or chronic lymphocytic leukemia. A myeloproliferative syndrome with abnormalities in granulocytic, erythrocytic, and thrombocytic cell lines was present in all patients and in seven patients preceded ANLL by 2--18 months. The median time to the development of ANLL after primary disease therapy was 61 months (33--98 range). The leukemia was extremely refractory to therapy and median survival after diagnosis of ANLL was two months (range 0--9 months). Leukemia was seen only in those patients who received multiple courses and multiple techniques of radiation therapy.

Expression of the normally cryptic blood group antigen Tn has occasionally been reported in hematologic disease, but the true frequency of this change is not known. A mouse monoclonal antibody (FBT3) and immunohistochemistry were used to examine expression of the Tn antigen. Expression was not detected in 35 normal bone marrow aspirates examined, but it was detected in 5 of 725 abnormal bone marrow aspirates, including 2 (3.6%) of 55 cases of de novo acute nonlymphocytic leukemia and 2 cases that terminated in acute nonlymphocytic leukemia. In two patients, one with acute myeloblastic leukemia and the other in blast transformation of chronic myeloid leukemia, the Tn antigen was expressed on 2 percent of blast cells. In one case of non-Hodgkin's lymphoma, 4 percent of normal myeloid cells expressed the antigen. In the other two cases, one of acute myelomonocytic leukemia and the other of myelodysplasia, only 2 to 8 percent of myeloid and erythroid cells initially were Tn positive. Subsequent serial immunohistochemical studies of bone marrow aspirates and peripheral blood in these two cases showed increasing numbers of Tn-positive erythroid and myeloid cells 8 to 12 months before polyagglutination was detected serologically. Tn-positive cells increased to > 90 percent in the terminal phase in both cases of both diseases. The results suggest that Tn expression in these two patients may have conferred a growth advantage to the cells and could be related to disease progression.

We have assessed levels of surface-expressed complement regulatory proteins, decay-accelerating factor (DAF) and membrane cofactor protein (MCP) on cells from patients with hematological malignancies. Neither malignant cells nor unaffected nucleated blood cells from the patients lacked MCP. On the other hand, complete deficiency of DAF was found in 2/10 of non-Hodgkin's lymphoma (NHL), while none of the 38 patients with acute nonlymphocytic leukemia (ANLL) (14 cases), chronic myelogenous leukemia (CML) (6 cases), acute lymphocytic leukemia (ALL) (12 cases) and chronic lymphocytic leukemia (CLL) (6 cases) lacked DAF. The two patients with DAF-negative NHL had no history of paroxysmal nocturnal hemoglobinuria (PNH), and their peripheral blood cells were DAF-positive. One DAF-negative NHL exhibited T cell markers and the other those of B cell. In both cases, treatment of the DAF-negative lymphoma cells with antibody against MCP (M177) followed by Mg(2+)-EGTA-serum resulted in efficient deposition of homologous C3. These results infer that some NHL specifically lack DAF and, through treatment with M177, are targeted by homologous C3.

We have report the results of cytogenetic studies carried out in eight patients with acute nonlymphocytic leukemia developed after primary neoplasias. In seven of the reported cases, clonal chromosome aberrations were found, some being specific of de novo acute nonlymphocytic leukemia (ANLL). Numerical abnormalities were detected, such as the total monosomy of chromosomes 5, 7, 21, trisomy of chromosomes 8, 11, 15, and duplication of chromosome Y. Structural changes were also observed: a del(12)(p12), a del(16)(q22), the translocations t(3;5)(p21;q35),t(3;7)(p21;q35), and t(12;14)(p12;q32) and other changes involving chromosome 8. The finding of a hypertetraploid karyotype with complex structural chromosome aberrations in a patient with erythroleukemia, developed after non-Hodgkin's lymphoma, is of particular interest. Data reported in this work are discussed with regard to the relationship between secondary and de novo ANLL and the finding of chromosome aberrations other than total or partial monosomy of chromosomes 5 and 7 is emphasized.

The peripheral blood represents an alternative source of haemopoietic progenitors and permits autografting in patients who have contraindications for a bone marrow harvest but who are otherwise candidates for autologous bone marrow transplantation. Circulating stem cells can be harvested performing several leucaphereses during the overshoot after a mobilization chemotherapy. The use of Fenwal CS-3000 cell separator allows reproducibility from donor to donor and makes the procedure very efficient. We collected peripheral blood stem cells (PBSC) in four patients, 2 with Hodgkin's lymphoma, 1 with high-grade non-Hodgkin's lymphoma and 1 with secondary FAB unclassifiable ANLL: the procedures of collection and cell harvests obtained are reported.

The risk of second primary cancer (SPC) was evaluated in 947 patients treated for Hodgkin's disease (HD) during the period January 1969 to December 1979. The median follow-up of this series was 10.5 years (range, 9 to 19). Treatment categories included radiotherapy (RT) alone (115 patients, 12%), chemotherapy (CHT) alone (161 patients, 17%), combined RT plus CHT (381 patients, 40%), and salvage treatment for resistant or relapsing HD (290 patients, 30.6%). Fifty-six SPCs were observed, occurring between 1 and 17 years from initial treatment. Among these, secondary acute nonlymphoid leukemia (s-ANLL) was the most frequent SPC (23 cases). Secondary non-Hodgkin's lymphoma (s-NHL) occurred in 5 patients, whereas a secondary solid tumor (s-ST) was observed in 28 patients. The calculated actuarial risk (+/- SE) of developing SPC was 5.0% (+/- 0.9%) and 23.1% (+/- 5.8%) at 10 and 19 years, respectively. Concerning treatment modalities and s-ANLL risk, no cases were observed in the radiotherapy group, whereas CHT plus RT and salvage groups showed the highest actuarial risk. This was, in fact, at 10 and 19 years, 3.1% (+/- 0.9%) and 8.1% (+/- 4.0%) in the former group, and 1.8% (+/- 1.0%) and 16% (+/- 9.0%) in the latter. A statistically significant difference was observed when the CHT plus RT group was compared with CHT and RT groups (P = .04). Concerning the relationships with chemotherapeutic regimens, 12 s-ANLL cases occurred in the mechlorethamine, vincristine, procarbazine, and prednisone (MOPP) plus RT group, and only one case in the group receiving doxorubicin, bleomycin, vinblastine, and dacarbazine (ABVD) plus RT. A statistically significant difference of s-ANLL actuarial risk was found comparing patients receiving MOPP plus RT to all other treatment groups (P = .04). With respect to s-ST, the actuarial risk at 10 and 19 years was 2.0% (+/- 0.6%) and 13.0% (+/- 3.8%), respectively. No significant differences were found among groups treated with different modalities. These data were confirmed by a multivariate analysis, which indicated treatment modality and age as independent variables for s-ANLL and s-ST development, respectively. Based on the prolonged follow-up analysis, the actuarial SPC risk at 10 years hereby reported should reflect the real SPC incidence in our series.

The risk of second malignancies following non-Hodgkin's lymphoma (NHL) was estimated in 29,153 patients diagnosed with NHL between 1973 and 1987 in one of nine areas participating in the National Cancer Institute's Surveillance, Epidemiology, and End Results Program. Compared with the general population, NHL patients were at a significantly increased risk of developing second cancers (observed/expected [O/E] = 1.18; O = 1231). The O/E ratio increased significantly with time to reach 1.77 in 10-year survivors. Significant excesses were noted for acute nonlymphocytic leukemia (O/E = 2.88), cancers of the bladder (O/E = 1.30), kidney (O/E = 1.47), and lung (O/E = 1.57), malignant melanoma (O/E = 2.44), and Hodgkin's disease (O/E = 4.16). Chemotherapy appeared related to subsequent acute nonlymphocytic leukemia (ANLL) and bladder cancer. Radiation therapy was associated with ANLL and possibly cancers of the lung, bladder, and bone. Malignant melanoma was not clearly related to initial NHL treatment.

Using a database comprising 13,266 cytogenetically abnormal neoplasms, the geographic heterogeneity of neoplasia-associated chromosomal abnormalities was investigated by comparing the frequencies of characteristic aberrations in consecutive series of patients with the same diagnosis. Significant frequency differences between geographic areas were found for the aberrations +8, i(17q), +19, and an additional Ph1 chromosome in chronic myeloid leukemia (CML); -5, 5q-, and +8 in acute nonlymphocytic leukemia (ANLL); t(8;21) in ANLL-M2; t(15;17) in ANLL-M3; 5q- and -7 in myelodysplastic syndromes (MDS); t(9;22) and +21 in acute lymphocytic leukemia (ALL); t(14;18) in follicular lymphoma; -8 and -22/22q- in meningioma; and structural abnormalities of 12q in pleomorphic adenoma of the salivary glands (PAS). No geographic incidence variation was detected for -7 and +21 in ANLL; +8 in MDS; 6q- and +8 in ALL; +12 in chronic lymphocytic leukemia; 6q- in non-Hodgkin's lymphoma (NHL); t(8;14) in Burkitt's lymphoma; t(11;22) in Ewing's sarcoma; i(12p) in germ cell tumors; 1p- in neuroblastoma; structural abnormalities of 3q, 8q, and 9p in PAS; or 3p- in renal cell carcinoma. Intraregional frequency similarities between cytogenetically identical abnormalities in related tumor types were also analyzed. No significant correlations were found regarding the incidence of 5q- in ANLL and MDS, 6q- in ALL and NHL, -7 in ANLL and MDS, +8 in ANLL and CML, +8 in ANLL and MDS, +8 in ALL and ANLL, or +21 in ALL and ANLL. The findings indicate that some geographic heterogeneity of tumor-associated aberrations exists both in hematologic neoplasms and in solid tumors.(ABSTRACT TRUNCATED AT 250 WORDS)

Diaziquone (AZQ), a synthetic quinone with demonstrated activity against acute nonlymphocytic leukemia (ANLL), primary CNS tumors, and non-Hodgkin's lymphoma (NHL), is virtually devoid of nonhematopoietic toxicity at conventional doses. As a prelude to its inclusion into bone marrow transplant (BMT) preparative regimens, a phase I study of high-dose AZQ with autologous BMT (ABMT) was performed. Patients with refractory solid tumors and lymphomas were treated with a single 24-hour infusion of AZQ at 50 to 355 mg/m2 in dose escalations of 20%. Fifty-six patients received 69 courses. Those receiving greater than 60 mg/m2 had nadir granulocyte and platelet counts less than 500/microL and 20,000/microL, respectively. Nausea, vomiting, stomatitis, and diarrhea were mild, transient, and not dose-related. Transient minimal elevations of liver function tests were seen in five patients and were also not dose-related. The maximally tolerated dose (MTD) of high-dose AZQ was found to be 245 mg/m2, with nephrotoxicity being dose-limiting. Significant azotemia was seen in four of 12 patients treated at 295 and 355 mg/m2, including fatal anuric renal failure in three of these patients. Reversible proteinuria also occurred in 24 of 26 courses above 150 mg/m2, including nephrotic range proteinuria in eight courses, all at doses of 205 to 355 mg/m2. The proteinuria was also associated with multiple proximal tubular defects including generalized aminoaciduria and proximal renal tubular acidosis. There were six early deaths including two of early renal failure (295 and 355 mg/m2), two of sepsis (205 and 245 mg/m2), one of a pulmonary embolus (85 mg/m2), and one of progressive disease (60 mg/m2). Of 50 patients who were assessable for response, there were seven responses including two of 10 with primary CNS tumors, one of 12 with malignant melanoma, one of five with non-small-cell lung carcinoma, two of two with breast carcinoma, and one of one with ovarian carcinoma. Because of its activity in ANLL and NHL and its unique toxicity spectrum, high-dose AZQ may improve the efficacy of current BMT preparative regimens without significantly increasing their nonhematopoietic toxicity.
