Abstract

Introduction

in patients with gastric cancer, in accordance with the increase of survival, bone metastasis are an emerging problem. In scientific literature there are few data about the natural history of bone disease in gastric cancer. We report the preliminary data of a large Italian multicenter survey.

Methods

142 patients with gastric cancer and with evidence of bone metastases have been included in the study. All patients were died due to cancer at the moment of the study inclusion. Clinico-pathological data, data on survival and Skeletal Related Events (SRE) have been collected in a master database and analyzed.

Results

96 males and 46 females; median age: 62 (19-80); patients with bone metastases at the moment of gastric cancer diagnosis: 23.2%; patients with single bone metastasis: 11.3%, patients with multiple metastasis 88.7%; lytic type: 49.3%, mixed: 19.7%, blastic: 27.5%, no data 3.5%. Sites: spine (78%), pelvis (65.5%), long bones (54%), other (27%). Median time to bone metastases: 7 months (0-132). Patients with at least 1 SRE: 31.7%. Types of SREs: pathologic fracture (27.7%), radiotherapy (43.1%), spinal compression (9.3%), bone surgery (13.8%), hypercalcaemia (6.1%). Median time to first SRE: 1 (0-65). Median survival after bone metastasis diagnosis: 5 (0-48).

Conclusions

The present survey is the result of the largest Italian descriptive study concerning the natural history of bone disease in gastric cancer patients.
