Summary
This phase I trial studies the side effects of ketorolac before surgery in treating patients with stage I-II non-small cell lung cancer or stage III renal cell cancer. Surgical trauma increases the production of prostaglandins and thromboxanes, which have tumor-promoting and immunosuppressive activities and reduce the activity of natural killer cells, which impairs the ability of the immune system to keep cancer cells in check. However, if given just before tissue injury, non-steroidal anti-inflammatory drugs, such as ketorolac, may be able to block the production of prostaglandins/thromboxanes and boost the activity of natural killer cells, thereby decreasing the risk of cancer coming back.
