Abstract :Purpose:The aim of this stduy is to examine the distribution properties of pelvic bone metastases according to primary cancers and to reveal the properties of additional bone metastases that may accompany pelvic bone metastasis. Patients and Methods:151 patients with pelvic bone metastases and without visceral metastases were included in the study. Clinical data, pathological diagnostic reports and PET-CT results of 151 patients were evaluated. The patients were evaluated in terms of age, gender, number of pelvic bone metastases (single focus, multiple focus) and localization of pelvic bone metastasis(sacroiliac joint, sacrum, ilium, ischium, pubis, acetabulum). Results:Multiple pelvic metastasis frequency was significantly higher in the females (80.00%) than in the males (61.46%) (p=0.030). The most common location of the metastasis was ilium for both genders. The most common location of the metastasis was ilium for the breast (61.76%), prostate (44.44%) and gynecologic (66.67%) cancers. The most common locations of respiratory system cancers metastasis were sacrum (54.29%) and ilium (54.29%). Acetabulum was the most common metastasis location for gastrointestinal (72.73%) and urinary (58.33%) tract cancers. Conclusion:As the result of this study the ilium is the the most common metastatic bone region of the pelvis. Primary cancers often tend to cause multiple metastases to the pelvic bone. Evaluating the metastases of the pelvic ring with larger number of cases may provide clues in finding the tumors of unknown primary.
