Patient: Diagnosed with rectal cancer in March ’09. Anal preservation surgery was performed on April 6, 2009, and 6 chemotherapy sessions were completed afterwards. After that, the body recovered quite well and there was no abnormality. Six months later, the diagnosis was reviewed: 1. post-operative rectal cancer, focal glucose hypermetabolism in the rectal and anal canal area, and local recurrence. 2. Slightly hypodense shadow under the envelope of the left lobe of the liver, with increased glucose metabolism, firstly consider the sign of malignant lesion. 3, Localized hypodensity of bone in the 11th thoracic vertebra with abnormally increased glucose metabolism, first consider bone metastasis sign. What are the treatment options? Gastrointestinal tumors with metastases to liver and bone after surgery are not very sensitive to radiotherapy and have poor prognosis, so palliative treatment is recommended. Decompression surgery can be considered if there are symptoms of nerve compression in the spine. Currently, prophylactic vertebroplasty (bone cement injection enhancement) can be considered. Pay attention to the prevention of pathological fracture. Some foreign studies have shown that the 3-year survival rate of rectal cancer bone metastases is extremely low, and surgery is not recommended.
