C h r o m o s o m e 1 Aberrations in Cancer Niels B. Atkin
ABSTRACT: Evidence for chromosome #1 involvemenl in structural rearrangements in cancer is reviewed. There have been adequate studies of cancer at most of the common sites, and at all of these, nonrandom chromosome #1 involvement has been demonstrated. In general, a variety of changes is encountered, irrespective of the site; most commonly, however, the changes result in the duplication of long arm material. It seems that these nonrandom changes, which" tend to occur at a relatively late stage, may contribute to the progression of all forms of cancer. However. a small number of chromosome #1 aberrations are also now known, which may represent specific and possibly initiating changes in particular forms of cancer. These include short arm deletions in neurohtastoma and translocations in leukemias and myelodys-
plasio. The literature contains n u m e r o u s reports of chromosome #1 aberrations in various types of h u m a n malignancy. This is often one of the two or three chromosomes that most frequently undergo structural changes in a given type of cancer. In an attempt Io document the extent of chromosome #1 i n v o l v e m e n t in cancer as a whole, I have assembled relevant reports relating to all the types of malignancy that so far appear to have been adequately studied (Table 1). I have not attempted to draw up a comprehensive list of all tile relevant papers, but merely show that there have been sufficient studies to demonstrate n o n r a n d o m chromosome #1 structural changes at each of the listed sites. Papers that only report findings on established cell lines have been excluded, because chromosome #1 changes may occur during culture [1]. Although some gaps are apparent in the list (there do not appear to have been adequate studies of carcinomas of the stomach or corpus uteri, for instance), there would still seem to be sufficient grounds for the assumption that chromosome #1 abnormalities play a role in the evolution of all types of malignancy. This would suggest that they are associated with an event that is c o m m o n to malignancy as a whole, rather than one that is restricted to neoplasms originating from a particular cell type (like the various tumor type-specific changes involving other chromosomes that have recently been described). Trisomy for bands lq25-1q32 was observed by Rowley [19] in 1977 to be the c o m m o n d e n o m i n a t o r in a series of patients with myeloproliferative disorders who had chromosome #1 aberrations, and subsequent studies have confirmed the frequent duplication of this region (or 1q21-1q32) not only in myeloproliferative disorders, but also in many other forms of cancer (Table 1). There is growing evidence, however, that, as well as chromosome #1 changes that are c o m m o n to all forms of

Apart from the few specific c h a n g e s a l r e a d y m e n t i o n e d , c h r o m o s o m e changes in cancer, i r r e s p e c t i v e of site or cell type, may be s u m m a r i z e d as follow
#1 Aberrations in Canc:er
281
In a proportion of neoplasias at a given site, no structural aberrations are found, but such neoplasias may show trisomy 1, or a relative excess of c h r o m o s o m e s #1. where the c h r o m o s o m e n u m b e r is high. Where present, structural changes commonly (though not invariably] result in an excess of long arm material. The 1 p chromosomes are c o m m o n and, in near-diploid neoplasias, are usually accompanied by at least two normal (t)r abnormal) c h r o m o s o m e s #1 (e.g., in carcinomas of the bladder [2] and cervix uteri [91). Other types of abnormal c h r o m o s o m e #1 may be a c c o m p a n i e d by one, two or more normal (or abnormal} chromosomes #1; among these abnormal chromosomes, long arm isochromosomes are common, as is the a d d i t i o n of material from lq or from other c h r o m o s o m e s to either arm of a c h r o m o s o m e #1. Aberrations less often encountered are short arm isochromosomes and long arm deletions. In neuroblastomas, the loss or rearrangement of material on the c h r o m o s o m e #1 short arm was found in over 70% of tumors, the most frequent breakpoint being lp32, and it was suggested that the loss of activity of one or more genes on the distal part of l p (distal to lp31} may be important in tile d e v e l o p m e n t of neuroblastomas, in which deletions of l p are common, but trisomy for any portion of c h r o m o s o m e #1 is rare [1, 54]. A d d i t i o n a l c h r o m o s o m e # l long arm material was, however, present in 37% of the tumors Ill and may represent a late change that is related to tumor progression. It has frequently been suggested that c h r o m o s o m e #1 aberrations are relatively late events in malignant progression. Thus, they are rarely present in the chronic phase of chronic myeloid leukemia, whereas they are not u n c o m m o n in the acute phase and may indicate a poor prognosis 132]. However, c h r o m o s o m e #1 aberrations in chronic m y e l o i d leukemia may be related to previous treatment; in one interesting report [73], they were found in patients who had been treated in the chronic phase by intensive t:hemotherapy, but not in those treated by b u s u l p h a n alone. Although data on the preinvasive phase of carcinomas are scanty, two reports indicate that c h r o m o s o m e #1 structural changes may precede stromal invasion in the cervix uteri 112, 74J. In one of these reports ]741, the aberration found in both a carcinoma in situ and a carcinoma in situ with a small focus of invasive tumor was the relatively u n c o m m o n l q - anomaly. Both these lesions had near-triploid modes, and the chromosome #1 markers were present in duplicate. Quite frequently, however, invasive tumors with near-triploid or h y p o t e t r a p l o i d modes have only single copies of c h r o m o s o m e #1 markers (although two or three different markers may be present}, e.g., in the cervix uteri [11J, b l a d d e r [3], and prostate [60], indicating that either the markers a p p e a r e d after the evolving neoplastic stemline underwent c h r o m o s o m a l doubling, or (perhaps less likely) they had taken part in a chromosomal doubling, but one of the d u p l i c a t e d markers had subsequently been lost. Four oncogenes have been assigned to c h r o m o s o m e # 1 : N - r a s - 1 (to l p l l - p 1 3 I75]), Blym-1 ( l p 3 2 [76]), c-src ( l p 3 4 - p 3 6 [771, and SK (1q12-qter [78]). Also, four "constitutive" fragile sites have been located on c h r o m o s o m e #1 (1p31.2, p21.2, q21.3, and q44.1) [79]. W. F. Benedict et al. 180] found that, in near-tetraploid hybrids between a h u m a n fibrosarcoma cell line (which contains an activated N-ras-1) and normal fibroblasts, a loss of c h r o m o s o m e #1 was correlated with the reexpression of tumorigenicity. As a possible mechanism for this reexpression they suggested the loss of a gene present in the normal fibroblasts that could suppress tumorigenicity (perhaps by specifically regulating the expression of the activated N-ras-1, gene); this gene might be the normal N-ras-I allele. Malignancy was not s u p p r e s s e d in near-hexaploid hybrids that contained an a p p r o x i m a t e l y doubled fibrosarcoma and a single normal fibroblast c h r o m o s o m e complement, suggesting that the tumorigenicity is chromo-
