However, patients with a recurrence\-free period of at least 5 years; those with basal cell carcinoma or spinous cell carcinoma of the skin that was eventually cured after receiving local treatment; and those with superficial bladder cancer, cervical cancer, carcinoma in situ, intramucosal cancer (that can be treated endoscopically), and nonmetastatic prostate cancer (that does not require systematic treatment) can be registered. 2\. Pre\-operative treatment (chemotherapy, radiation therapy, immunotherapy) is administered or planned prior to metastasis resection Exclusion criteria for the retrospective cohort 1\.
