Area of Science:

Hematology
Oncology
Cytogenetics

Background:

Multiple myeloma is a hematologic malignancy characterized by clonal plasma cell proliferation.
Understanding the genetic landscape of myeloma is crucial for predicting treatment response and relapse.

Observation:

Cytogenetic analysis was performed on a patient with IgG kappa multiple myeloma before and after treatment.
The initial neoplastic clone consisted of 55,XX cells.

Findings:

Following therapy and clinical response, the patient relapsed with a clone of 57,XX cells.
These cells were identified as derivatives of the original neoplastic cell line, indicating clonal evolution.

Implications:

This case provides the first cytogenetic evidence of myeloma clonal evolution in a patient pre-treatment.
