Why Randomized Surgical Oncology Trials Are So Scarce
About half of patients with solid tumors are cured by surgery alone. And yet randomized clinical trials in surgical oncology remain scarce.
Surgical oncologists offer various explanations: the difficulty of ensuring uniformity in surgical practice; the lack of funding by the pharmaceutical industry; and in the United States, the absence, until recently, of a surgically oriented cooperative clinical trials group.
Elma K. Kranenbarg, and Cornelis J. H. van de Velde, M.D., Ph.D., of the University of Leiden in the Netherlands published an editorial in a recent Japanese Journal of Clinical Oncology on the importance of surgical trials in oncology. They make a plea for greater participation of surgeons in clinical trials, and for closer attention to surgical variables in all cancer trials.
