Detection of Bone Metastasis On Whole Body Bone Scan Among Sudanese Patients with Proven Cancer in Tumours Therapy and Cancer Research Center –Shendi –Sudan

Abstract

Bony metastasis is one of the most common causes of death in patients with proven cancer, most of the patients present by pathological fracture, and carry poor prognosis. The bone scan is the main investigation for diagnosis. Our objective is to determine the most common cancer that causes metastasis, the commonest site involved in the skeleton, and the metastatic pattern for each cancer. We studied 150 cases collected in tumor therapy and cancer research centers, those who underwent bone scans using a gamma camera. The most age of our patients ranged between (40 and 60) years old. The predominance of females was noticed (68.7%). 90% of the patients were married. The study showed that 35.3% with left breast cancer, 20% with right breast cancer, and 22% with prostate cancer. The study showed that 40% of the participants had bone metastasis, 41.7% with prostate cancer, 21.7% with left breast cancer, and 16.7% with right breast cancer. The study showed that the lumber vertebra involved in 51.7% of bone metastasis, thoracic vertebra involved in (50%) with bone metastasis, the anterior ribs involved in 28.3% with bone metastasis, while posterior ribs in 25%, the right femur involved in 28.3 while the left femur engaged in 25% of bone metastasis and 25% metastasis to the skull. About 40% of the patients had bony metastasis. Breast and prostate are the most common cancers that cause bony metastasis. The spine is the most common site for metastasis. Prostate cancer metastasized mainly to the spine followed by the femur, ribs, skull, and shoulders Keywords: bony metastasis, bone scan, cancer patient, Shendi –Sudan
