Abstract
Aberrations of the C-band region of chromosome no. 1 (1qh) were studied in 109 patients with ovarian cancer and 192 healthy subjects. The groups were compared for heterochromatin size variations, intrapair size asymmetry, and inversion. No significant correlation was found between the size of 1qh and ovarian cancer. Heterochromatin size asymmetry was estimated visually and determined by objective measurement of 1qh length or area; the methods show strong correlation. The measurements were normalised by comparison with the length or area of 16p or the entire chromosome no. 1. However, since good reliability was found by simply relating the 1qh size difference to the mean 1qh size, this was considered an appropriate and simpler method of normalisation. Asymmetry indices of length and area measurements correlated well, implying that the simpler method of length measurements can be readily used. 1qh asymmetry, measured objectively or estimated visually, was significantly increased in the cancer patient group. The incidence of C-band inversion was significantly increased in the patient group. Moreover, inversion increased significantly with increasing 1qh asymmetry.

Abstract
The C-band heterochromatin polymorphism of chromosomes 1, 9, and 16 was studied in lymphocytes from 53 patients with Ph1-positive chronic myeloid leukemia (CML) and 183 control persons. The patients had significantly larger heterochromatic blocks on chromosome 16 (p less than 0.01) and fewer partial inversions of chromosome 9 (p less than 0.05) than the control persons, whereas no differences were found for the symmetry/asymmetry pattern. We suggest that the increased constitutive heterochromatin regions may, via sister chromosome exchange, facilitate homo- or hemizygotization of genes which favor neoplasia development and/or progression.

Abstract
Multiple myeloma (MM) is a malignant plasma cell disorder that involves multiple genetic abnormalities. Chimeric transcription factors, created by gene fusion as a result of chromosomal translocations, have been implicated in the pathogenesis of the disease. Here, we report the conventional cytogenetic analysis of a MM patient that showed a complex set of novel chromosomal rearrangements, including t(13;16)(q14;q24) and t(1;15)(q10;q26). This is probably the result of fusion of previously known genes, and would contribute to prognostic significance of the disease.

Abstract
Stratification of patients with multiple myeloma according to clinical severity was attempted by chromosomal analysis of 180 bone marrow specimens from 79 patients. The 79 patients were hospitalized and treated between 1994 and 1999. Abnormalities of chromosome 1 were detected at the initial medical examination in 8 (10%) of the 79 patients and were found during follow-up in additional 3 patients. Abnormalities of chromosome 1 were often detected in IgA (4/17) and IgD (2/4) multiple myeloma, while detection in IgG myeloma was relatively rare (4/42). The relevant break points were 1q12 in 5 patients and 1q42 and 1q21 in 3 patients, while 3 patients had trisomy 1. Deficiency of the long arm of chromosome 13 was detected in 6 patients, and this was believed to imply a prognosis. The long arm was completely deleted in 2 patients and part of the arm (13q10-14) was deleted in 4 patients. It is interesting that all 6 patients had concomitant abnormalities of chromosome 1. Although the initial response to treatment of patients having abnormal chromosomes 1 and 13 was comparable to that of patients having other chromosomal abnormalities or patients who were karyotypically normal, the median survival time was only 18 months (p < 0.02). Consequently, aggressive treatment such as early stem cell transplantation and so on is needed to improve their survival.

Abstract
We present a 71-year-old patient with chronic lymphocytic leukemia diagnosed 27 years ago. Initially, the disease was staged as Rai II and the patient suffered from secondary immunoglobulin deficiency. Nevertheless, no treatment was necessary at that time. Because of disease progression a single course of chemotherapy was given in 1984. During the following year there was a constant decline of the WBC, accompanied by normalization of the immunoglobulins; both have remained stable ever since that time. However, there was still residual bone marrow infiltration, indicating persisting CLL. In 1993 cervical lymphadenopathy occurred with acute onset. A diagnostic lymphadenectomy revealed Hodgkin's disease of the nodular-sclerosing subtype. The patient was staged as II-III according to the Ann Arbor Classification and underwent radiation therapy. Cytogenetic examination of the bone marrow revealed a normal karyotype with an inversion of chromosome 9. This case demonstrates the rate coincidence of two lymphoproliferative disorders in the same patient. The clinical course and the immunologic findings of this patient are presented, together with a review of the literature.

Abstract
The chromosomes of 111 ovarian cancer patients were studied in G- and C-banded slides from peripheral blood lymphocyte (PBL) cultures for chromosome damage caused by chemotherapy and radiotherapy and for asymmetry of the constitutive heterochromatin of chromosomes 1, 9, and 16. We also monitored the survival of these patients to determine whether any secondary neoplasia induced by the therapy and report the findings of our investigations. Melphalan (MEL) was the only drug used in single-drug chemotherapy. The incidence of chromosome abnormalities in melphalan-treated cells (25%) was higher than in the control group (17%). The incidence of structural changes was also higher (10.5%) in the MEL-treated group than in controls (6%). After treatments with combinations of drugs, the incidence of structural changes remained at the same level (11%). In the patients receiving combined treatment with MEL and radiation, the rate of structural changes increased dramatically (24%). The overall rate of chromosome aberrations in this group was also higher (50%). Combination of two or more drugs and radiation produced only 14% structural chromosome changes. The overall rate of chromosome aberrations was also low (20%) in this group. Of 111 patients studied, only 33 were alive 6 years after initiation of the study. Of the surviving patients, eight had rearranged chromosomes in the first analysis. After 5 years, new blood samples were collected from these patients and chromosome analyses showed abnormal karyotypes in all eight patients. All chromosome abnormalities in the second analysis were completely unrelated to those in the first analysis, however. Whether the chromosome changes in the second analysis were due to therapy or to other unknown factors could not be determined. Data on C-banding and the distribution of inversions indicated that 91% of the patients had C-band heteromorphisms of chromosomes 1, 91% had heteromorphisms of chromosome 9, and 69% had heteromorphisms of chromosome 16. Furthermore, inversions were observed in chromosome 1 (41% of patients), chromosome 9 (28% of patients), and chromosome 16 (5% of patients).

Abstract
The C-band heterochromatin polymorphisms of chromosomes 1, 9, and 16 were studied on peripheral lymphocytes of 67 children with acute lymphoblastic leukemia (ALL) and 50 control individuals. A statistically significant difference between patients and controls was found for large heterochromatin regions (level 3) of chromosomes 1 and 9 (P < 0.001) and for small heterochromatin regions (level 1) of chromosome 16 (P < 0.001). The patients also showed a significant increase in chromosomes 1 and 9 heteromorphism with respect to controls (P < 0.001).

Abstract
We report two cases of monocytic leukemia associated with cytogenetic changes involving the juxtacentromeric heterochromatin of different chromosomes. In a patient with chronic myelomonocytic leukemia (CMMoL) we describe a translocation t(1;9)(q12;q13) in which the duplicated derivative chromosome 9q + showed a huge centromeric C-band, derived by fusion of the heterochromatic regions of chromosomes 1 and 9. The constitutional karyotype showed two heterochromatin polymorphisms, 1qh + and inv(9qh). In the second case, an acute monoblastic leukemia was associated with an abnormally elongated juxtacentromeric heterochromatic region of chromosome 4 that was not constitutionally present.

Abstract
Fifty-six patients with blood disorders (23 with chronic myeloid leukemia, 14 with acute myeloblastic leukemia, seven with acute lymphoblastic leukemia, one with chronic lymphocytic leukemia, and 11 with preleukemia states) were studied. A quantitative and objective method of C band length analysis with well-matched controls was used. The C bands of chromosome pairs 1, 9, and 16 presented a normal distribution that was similar in patients and controls, whereas the Y chromosome presented an abnormal distribution. Smaller C bands in 1qh and higher indexes of intrapair heteromorphism in pairs 1 and 9 were detected in the CML group; the group of acute leukemias (myeloblastic and lymphoblastic) presented a smaller index only in pair 1qh. No other differences in length, heteromorphism, inversion frequency, or sex were detected.

Abstract
A study of heterochromatic regions in chromosomes #1, #9, and #16 was performed on lymphocytes of peripheral blood from 55 normal individuals and 50 patients with non-Hodgkin's lymphoma (NHL). Heteromorphism was present in 90% of the NHL patients, compared with 44% in normal individuals (p less than 0.001). An increase of inv(1), 1qh-, and 9qh-variants was observed in malignant lymphoma patients with respect to controls.

Abstract
C-band polymorphisms in peripheral blood lymphocytes of 62 patients (33 with colon adenomas and 29 with colon carcinomas) were studied. A significant difference in the frequency of heterochromatic variants in chromosomes #1 in both colon adenoma (56%) and carcinoma (67%) with respect to controls (18%) was observed (p less than 0.001). The heterochromatic variants preferentially involved in both pathologies were inv(1), 1qh-, and inv(9), compared with controls. No differences were found between colon adenomas and carcinomas. We suggest that 1qh- and inv(1) variants are important heterochromatic changes in neoplasia.
