Case report finds spontaneous tumor regression in colorectal cancer after stopping interleukin-6 treatment, suggesting new avenues for research.
INTRODUCTION: Spontaneous cancer regression is exceptionally rare, particularly in colorectal cancer. Tumor regression has been reported in some patients with autoimmune diseases or organ transplants, after cessation of immunosuppressive therapy; however, its underlying mechanisms remain unclear. We report a rare case of Stage IVA transverse colon cancer with synchronous liver metastasis that showed complete pathological regression in both sites after discontinuation of tocilizumab, an interleukin-6 receptor inhibitor.
