Bone metastasis of rectal cancer is already in advanced stage in clinical staging, and the possibility of cure is relatively small, but after active anti-tumor treatment, the survival time of patients can be prolonged, so bone metastasis of rectal cancer is still salvageable. At this time, systemic treatment is the main focus, such as systemic chemotherapy, and if the economic conditions can be considered, anti-tumor angiogenesis targeted drugs, such as bevacizumab combined with chemotherapy can also be considered for treatment. Through comprehensive treatment, the survival time of patients can be significantly extended, and even long-term survival with tumor can be achieved. If the bone metastasis is a single bone metastatic lesion, then if both the rectal cancer lesion and the bone metastatic lesion can be resected, it is also possible to be cured in this case.
