Abstract:
The bone is a common site of metastasis for gastric cancer. High-risk factors of metastatic gastric cancer include young age, poorly differentiated adenocarcinoma, Borrmann type III tumors, depth of invasion at Se and Pm levels, positive lymph nodes, and gastric cancer with concomitant body of stomach cancer. More than half of the transfer pathway belongs to the non-portal system. Cases of gastric cancer with bone metastasis but without liver metastasis accounted for 69%of the total gastric cancer cases, whereas the incidence rate of bone metastasis with lymph node metastasis (≥3 cm away from the primary lesion) was 27%. In addition to the tumor markers human chorionic gonadotropin and carcinoembryonic antigen, radionuclide scan of the bone metastasis provides diagnostic pathways and reliable basis for treatment. Chemoradiation and surgery as symptomatic treatments are alternative therapies for stomach cancer. Bone metastasis confers unfavorable prognosis, and the survival time is often less than six months.
