Choice of anesthesia method or analgesics may affect the long-term outcome of cancer patients after surgery. I present here 12 papers documenting long-term metastasis, cancer recurrence, and survival rates after various cancer surgeries. Five showed statistical significance, while 7 did not. Most studies were retrospective and some were small-scale. To properly address this issue, a large, prospective, randomized, controlled trial (RCT) needs to be conducted.
