Abstract

Objective: To determine the frequency of t(4;14) in multiple myeloma in Pakistani population and study the clinicpathological correlation of this translocation in myeloma patients.

Study Design: Cross sectional study.

Place and Duration of Study: This study was conducted at Armed Forces Institute of Pathology from Jun 2017 to May 2018 using non probability convenience sampling technique.

Methodology: A total of 53 newly diagnosed cases of multiple myeloma were included in the study. Patients were diagnosed as having multiple myeloma based on diagnostic criteria of international myeloma working group. Fish analysis was done for t (4; 14). Workup for end organ damage /myeloma defining events was done.

Results: Out of 53 patients, 16 (30%) were females and 37(70%) were males; the mean age of the patients was 59.81 ± 11.34 range from 37 to 87 years. Fish for t(4;14) was positive in eight (15%) patients while negative in forty-five (85%) patients. Patients with positive results have significantly deranged renal function tests and raised beta 2 micoglobulins levels as compare to t(4;14)negative patients.

Conclusions: Detection of t (4:14) in multiple myeloma patients not only has diagnostic value but is important in risk stratification of these patients and thus effect treatment decision.
