VILLARROEL F, Lizz Nataly et al. Prevalence of bone metastases detected by scintigraphy and frequency of cancer of primary origin. Gac Med Bol [online]. 2014, vol.37, n.2, pp.83-86. ISSN 1012-2966.

Objectives: to determine the prevalence of bone metastases, assessing the predominance respect to gender, age group, and to identify the frequency of primary cancers. Methods: this research type is descriptive, retrospective; I consider a cross-sample of 1593 studies performed bone scans with 99mTc MDP in the Nuclear Medicine Center Cochabamba during the period 2009 to 2013. Results: the prevalence of bone metastases obtained was 24.7%, male gender (65%) being the most affected compared to women (35%) group. The age group with the highest number of cases was 61-70 years. Relative to the source primary cancer the following data were obtained: prostate (59.3%); breast (26.2%), lung (4.6%), cervical cancer (1.7%), myeloma multiple (1.7%); sarcoma (1.4%); kidney (1.1%), colon (0.9%) and others (3.1%). Conclusions: the prevalence of bone metastases in a quarter of the population, where the male was most affected was obtained. The age group with the highest number of tumors were in the adult population aged 61 years. Finally, in our study the primary origin of cancer was most frequent prostate, breast and lung followed over others.
