| Abstract: | Upfront treatment for patients with advanced high-grade serous ovarian cancer (HGSOC) includes a multi-hour cytoreductive surgery. Although the procedure is necessary for maximal tumor cytoreduction, understanding of the biology of systemic and intratumoral responses induced by surgical cytoreduction is limited. Through analysis of matched tumor and normal tissues and peripheral blood collected at multiple time points during cytoreductive surgery in patients with HGSOC, we demonstrate that surgery leads to rapid induction of systemic inflammatory response and activation of inflammatory signaling in the tumor and normal tissue, with interleukin-6 emerging as a dominant inflammatory pathway. A parallel study in a syngeneic murine HGSOC model recapitulated these findings and demonstrated accelerated tumor growth in response to surgery. This study highlights the previously unappreciated impact of specimen collection timing on the tumor signaling networks and provides insights into stress pathways activated by surgery, generating rationale for perioperative therapeutic interventions to reduce protumorigenic effects. © 2025 The Author(s) |
