ABSTRACT
The patient was a 47-year-old man whose condition was diagnosed as advanced lung adenocarcinoma with ROS1 rearrangement. He was also found to have sigmoid colon cancer and multiple liver tumors. His pulmonary lesions responded to crizotinib (CRZ), while the liver tumors increased in size. We therefore clinically diagnosed the patient’s condition as liver metastasis from colon cancer. Five months after starting CRZ, cytotoxic chemotherapy for colon cancer was initiated. Adverse effects other than those previously reported for each treatment were not recognized. We report this interesting case because, to the best of our knowledge, there are no reported cases of advanced lung cancer treated with CRZ while the patient also undergoes chemotherapy for metachronous colon.
