Patient: Description of the condition (onset time, main symptoms, hospital visited, etc.): Around the New Year’s Day 2012, I felt a feeling of cramping in my lower abdomen. The patient was found to have a rectal mass during the outpatient examination of the prostate gland at the Second Hospital of Harbin Medical University. No other symptoms. Now, you are being hospitalized in chemotherapy at Harbin Medical University Hospital. The most effective treatment plan is requested. Thank you! Hospital: Rectal cancer liver metastases are divided into two categories: simultaneous liver metastases and heterogeneous liver metastases; for patients with liver metastases and rectal primary foci found at the same time there are also two categories: liver metastases can be removed and unresectable, for the former you can choose to remove surgically first and then chemotherapy or first systemic chemotherapy and then do simultaneous primary foci and metastases removed or staged resection; for patients who cannot be removed choose systemic chemotherapy and then resection of the rectum Whether resection can be obtained after treatment of the primary lesion plus systemic chemotherapy and waiting for liver metastases. I am not sure about your condition, if I can upload your examination data, I can suggest the diagnosis and treatment; if I can come to my clinic it will be more straightforward.
