Abstract
Multiple myeloma (MM) is an ancient disease since bones
showing typical MM: lesions have been detected in archeological remnants. However, the
mortality trends in Malaysia suggest progressive increases in the incidence of the disease -
, during the past fifty years. Nevertheless, this must be interpreted with caution because ·
MM: may have been under-diagnosed. In addition, it has been well-established that MM is '
a disease of the elderly, as the incidence increases steadily with increasing age to a peak
age-specific incidence among people older than 80 years, with a median age of 65 years.
In addition, MM: has also been reported to be more of an urban disease, than it is a rural
one. Over the past few years, a different trend of occurrence ofMM has been noticed at the
Hospital University of Science of Malaysia, especially regarding age distribution and type
of environment, being urban or rural.
Materials and Methods: To study this remark systematically, records of all patients with
multiple myeloma at the Hospital ofUniversiti Sains Malaysia (HUSM), from 2005 - 2009
were reviewed. The data was collected and analyzed for the disease distribution according
to gender, age group and area of residence.
Results: Of the forty patients diagnosed with MM during the study period, in this study
25 (62.5%) patients were at the age group of 40-60 years. The remaining 15 (37.5%) were
more than 60 years of age. The median age was 56 years. The sex distribution showed that
twenty five patients (62.5%) were males and 15 patients (37.5%) were females, with a male
to female ratio of 1.6. The urban: rnral distribution was 1:3, with 10 patients from urban
areas, and 30 patients from rurat ·areas. Hence, 75% of all the 40 cases collected came from_
rural areas.
Conclusion: The data obtained show that the age distribution of MM in the study area is
lowered compared to most published reports. In addition, there is a rural predominance of
occurrence of the disease as compared to findings in previously reported studies. These
differences in the pattern of disease distribution may be attributable to environmental and
occupational factors, including the use of agricultural pesticides, or the presence of other
un-determined pollutants. Moreover, the possibility of genetic predisposition cannot be
excluded.
