Fatty acid differences amongst leukemia cell types, with special reference to hairy cell leukemia: a preliminary report.

Fatty acid analyses of malignant cells from hairy cell leukemia patients revealed a profile which was rich in arachidonate and relatively low in linoleate and oleate. This profile was distinct from that of mononuclear cells derived from patients with other lymphoproliferative diseases or myeloproliferative disorders, and may reflect the unique membrane morphology of the hairy cell.

Hairy cell leukemia: differences in phagocytic capacity of cells in vitro.

Hairy cells from eight patients with hairy cell leukemia were evaluated with both light and transmission electron microscopy for their capacity to phagocytose zymosan, latex, staphylococcus aureus, and pseudomonas aeruginosa. In two patients, there was no phagocytosis of any of these substances; cells from three patients phagocytosed only latex; two, all except pseudomonas; and one, all 4 substances. Hairy cells became relatively smooth while in culture with staphylococcus, but no surface changes were noted during incubation with the other substances. Of the eight patients studied, one died of pseudomonas pneumonia and sepsis; pseudomonas was the only substance which her hairy cells did not phagocytose. The one patient whose hairy cells phagocytosed all 4 test substances developed a disseminated Mycobacterium intracellulare infection; culture of his hairy cells with this atypical myocbacterium showed no phagocytosis. Hairy cells have different phagocytic capabilities from patient to patient, and the evaluation of these capabilities in vitro might provide early identification of potential infectious complications.

Evolution of karyotypes in Philadelphia (Ph1) chromosome-negative chronic myelogenous leukemia.

Ten of 55 patients with chronic myelogenous leukemia (CML) diagnosed between 1972 and 1977 were found to lack the Philadelphia (Ph1) chromosome. Serial clinical, morphologic, and cytogenetic studies of patients with Ph1-negative CML showed that 30% of them had chromosomal abnormalities. Two had an extra chromosome No. 8 at the time of blast crisis, with a morphological picture of myeloblasts in the bone marrow. A third patient had a 6:14 translocation initially Abnormalities of chromosome No. 14 are frequently seen in lymphoproliferative disorders, and the bone marrow and peripheral blood contained a significant population of lymphoblasts as well as myeloblasts. The median survival for the 10 patients was 19 months. The exact nature of Ph1-negative CML is not yet clear; disease appears to be a distinct entity among the myeloproliferative disorders.

Hairy cell leukemia: an autopsy study.

Autopsy material from 5 patients with hairy cell leukemia was examined. In addition to the expected widespread involvement of the hematopoietic system and of the liver, all of the patients had various amounts of pulmonary infiltration by leukemic cells. This infiltration was so severe in one instance that the resulting pulmonary insufficiency was the cause of death. Other areas of hairy cell infiltration included the peripancreatic connective tissue in all cases, kidneys in 3 cases, pericardium in 2 cases, and skin in 1 case. Association of plasma cells with the infiltrating neoplastic cells was prominent. In one patient, foci of large, bizarre cells were found in several lymph nodes and in the pericardium. Whether these cells represent transformation of the hairy cells into a larger, less differentiated cell type, or the emergence of a second hematopoietic neoplasm, is unknown.

Coexistence of leukemic reticuloendotheliosis and histiocytic lymphoma: a case report.

A 65-year-old woman had pancytopenia, splenomegaly, and an inaspirable bone marrow. Diagnostic evaluation demonstrated that she had both leukemic reticuloendotheliosis (LRE), or hairy cell leukemia, and an additional lympho-reticular neoplasm, most likely a "histiocytic" lymphoma. The diagnosis of LRE was based on the histopathology of spleen tissue and of a bone marrow biopsy specimen. The diagnosis of diffuse "histiocytic" lymphoma was based on the histopathology of a splenic hilar and a mesenteric lymph node, tumor nodules in the kidney and spleen, and tissue from a mass obstructing a ureter. This is the first well-documented association of a second lympho-reticular neoplasm with LRE. Even relatively gently treatment of the "histiocytic" lymphoma resulted in fatal pancytopenia, illustrating the restricitons on therapy imposed by the marrow impairment due to the LRE.

Pathologic stage I and II Hodgkin's disease, 1968--1975: relapse and results of retreatment.

Sixty-seven previously untreated patients with Hodgkin's disease, pathologic stages I and II, seen during a 7-year period were evaluted with respect to initial staging and treatment, as well as relapse and retreatment results. The initial treatment consisted of radiation therapy (RT) to an involved field (IF) or an extended field (EF) for patients with stages IA and IIA, or RT and, in recent cases, combination chemotherapy [cyclophosphamide, Oncovin, procarbazine, and prednisone (COPP)] for patients with stages IB and IIB. Nineteen of the 67 patients relapsed (28%), including 11 of 56 patients with stages IA and IIA (20%) and 8 of 11 patients with stages IB and IIB (73%). Seventeen of the 19 relapses occurred within 24 months after completion of the initial therapy (89%). The relapse-free survival at 5 years was 75% for the A patients and 25% for the B patients. The actuarial survival of stage IA and stage IIA patients at 5 years was 91%; there was no significant difference between patients treated initially with either IF or EF. The actuarial survival at 5 years for the patients with stages IB and IIB was 88%, as most responded to a second program of induction therapy. No correlation could be found between the pattern of relapse and the initial pathologic stage or the mode of treatment.

Chromosome analysis of primary large bowel tumors: a new method for improving the yield of analyzable metaphases.

Colon tumors were processed immediately after surgical resection. Using L-Arterenol and sodium citrate in combination with standard chromosome culture techniques, 12 of 17 consecutive tumors (75%) had countable figures ranging from 5 cells to 59 cells. Seven of the 12 cases had over 25 countable cells. Chromosome counts did not vary more than +/- 4 for any one case. Seven tumors were karyotyped, 6 with banding techniques. One of these specimens had mosaic patterns. The chromosome counts varied: 2 were hypodiploid; 1 was pseudodiploid and 4 were hyperdyploid. There were some similarities in the karotypes although no identical karyotypes were seen in this series.

The role of gallium-67 scanning in the clinical staging and preoperative evaluation of patients with carcinoma of the lung.

Gallium-67 scanning was evaluated in 100 patients with proved carcinoma of the lung. It was valuable in separating primary from secondary lung tumors, determining the extent of contralateral hilar or mediastinal lymph node involvement, and detecting distant organ metastases. In addition to multiplane whole-body Ga-67 tomographic scanning, colloid liver scans, bone scans, and computerized axial tomography scans of the brain were obtained to determine the presence of distant metastasis. The gallium scan detected 11 of 12 occult metastases and identified 7 of 7 liver, 9 of 14 brain, 4 of 4 soft tissues, 1 of 4 contralateral lung, and 9 of 11 bone metastases. The whole-body gallium scan accurately detected or excluded extrathoracic metastatic disease in 11 of 12 patients examined postmortem within three months of a gallium scan. An approach is recommended using gallium scanning along with chest roentgenograms for clinical staging and preoperative evaluation of patients with carcinoma of the lung. Specific organ scans should be reserved for the occasional symptomatic patient with a negative gallium scan or for clarification of an indeterminate gallium scan.

B cell acute lymphoblastic leukemia (ALL) with a 14q+ chromosome abnormality.

An adult patient with acute lymphoblastic leukemia associated with a 14q+ marker chromosome is presented. The abnormality resulted from a translocation of material from the long arm of chromosome 11. The leukemic cells were found to be B cells on the basis of surface immunoglobulins, lack of receptors for sheep erythrocytes, and a characteristically low level of adenosine deaminase activity. In other patients with ALL studied by us or reported by others in whom chromosome banding was done, a 14q+ chromosome was present in only one instance, also a case of B cell ALL. These two cases are the only examples of B cell ALL studied with chromosome banding reported to date. The frequent occurrence of a 14q+ chromosome in other malignant lymphoproliferative diseases of B cell origin suggests that a general association may exist between the 14q+ abnormality and B cell neoplasms. Cytogenetic analysis may therefore be useful in defining subtypes of ALL and in relating specific chromosomal abnormalities to lymphoproliferative disorders.

Hairy cell leukemia: effect of 'hairy' cells on normal granulopoiesis in vitro.

The effect of 'hairy cells' (HC) on proliferation of normal marrow granulocytic progenitor cells (CFU-C) was studied in vitro, using cells obtained from the blood, spleen, and bone marrow from eight patients with hairy cell leukemia (HCL). Hairy cells of hairy-cell-conditioned media (HCCM) did not stimulate proliferation of normal CFU-C. Furthermore, HC and HCCM did not inhibit the growth of CFU-C induced by normal colony stimulating factor (CSF) or by feeder layers of normal blood leukocytes. These results confirm previous reports showing the inability of HC to produce CSF and suggest that inhibition of CFU-C proliferation, as measured by this technique, is not an important mechanism in the neutropenia observed in HCL.

Banding studies of chromosomal abnormalities in patients with acute lymphocytic leukemia.

Karyotypes were analyzed by routine Giemsa and quinacrine fluorescence for 16 patients with acute lymphocytic leukemia [ten adults (18 to 51 years) and six children (3 to 15 years)]. Four patients had received previous therapy, but all 16 had active disease when they were first studied. Eight patients (five untreated) had a normal karyotype initially; however, three of these developed a chromosomal abnormality during relapse. Eight patients had a chromosomal abnormality in their initial samples. Each of the 11 patients had different abnormalities. All chromosomes except Nos. 3, 5, 15, 16, and Y were involved in the various aneuploidies. One patient had a Ph1 chromosome due to a translocation with No. 21: t(21;22)(q22;q11). A patient with B-cell acute lymphocytic leukemia had a 14q+ marker in addition to other abnormalities. The median survival of patients with initially normal karyotypes may be longer than that of patients whose karyotypes are abnormal initially.

Treatment of hairy cell leukemia (leukemic reticuloendotheliosis) II. Chlorambucil therapy in postsplenectomy patients with progressive disease.

Four postsplenectomy patients with progressive hairy cell leukemia were treated with daily low doses of an alkylating agent (chlorambucil, 4 mg). An objective response, measured by improvement in blood counts in four patients as well as decreased bone marrow involvement on core biopsy in three patients, could be documented within 6 mo. It is important to identify the postsplenectomy patient with progressive disease as early as possible in order to initiate low-dose single agent chemotherapy and have the time necessary to effect an objective response.
