Yy. Ozisik et al., TRISOMY-5 IN LONG-TERM CULTURES FROM BONE-MARROW OF PATIENTS WITH SOLID TUMORS, Cancer genetics and cytogenetics, 78(2), 1994, pp. 207-209
Long-term cultures of bone marrow from 15 cases diagnosed previously w
ith primary solid tumors were analyzed cytogenetically. Of these cases
, 10 had normal karyotypes and five had chromosomal abnormalities. Tri
somy 5 was found in four cases, three with trisomy 5 as the only chang
e and one with trisomy 5 and trisomy 12. These results suggest that tr
isomy 5 may be a nonrandom change associated with an in vitro or in vi
vo phenomenon.
