Human malignant melanoma. Significance of chromosomal abnormalities.
Although many reports on chromosome changes in human malignant melanoma (HMM) have been published, it is still impossible to define the significance of the different markers reported. In fact, we think that the difficulties in interpreting the chromosomal abnormalities could be due to poorly defined clinical conditions and a lack of correlation with cytological and histological analyses. To verify this hypothesis, we studied 10 cell lines obtained from 8 patients affected by cutaneous malignant melanoma that were well defined for their clinical, histologic, and cytogenetic aspects. No significant correlation was found among these parameters, and, hence, the cytogenetics findings cannot be used to determine a more detailed diagnosis or a more definite prognosis.
