Surgery is a crucial intervention and provides a chance of cure for patients with
cancer. The perioperative period is characterized by an increased risk for
accelerated growth of micrometastatic disease and increased formation of new
metastatic foci. The true impact for cancer patients remains unclear. This review
summarizes the often fragmentary clinical and experimental evidence supporting
the role of surgery and inflammation as potential triggers for disease
recurrence. Surgery induces increased shedding of cancer cells into the
circulation, suppresses antitumor immunity allowing circulating cells to survive,
upregulates adhesion molecules in target organs, recruits immune cells capable of
entrapping tumor cells, and induces changes in the target tissue and in the
cancer cells themselves to enhance migration and invasion to establish at the
target site. Surgical trauma induces local and systemic inflammatory responses
that can also contribute to the accelerated growth of residual and
micrometastatic disease. Furthermore, we address the role of perioperative
factors, including anesthesia, transfusions, hypothermia, and postoperative
complications, as probable deleterious factors contributing to early recurrence.
Through the admittedly limited understanding of these processes, we will attempt
to provide suggestions for potential new therapeutic approaches to target the
protumorigenic perioperative window and ultimately improve long-term oncological
outcomes. Cancer Res; 77(7); 1548-52. ©2017 AACR.
