Teacher: Now, understand the problem? Solve this instance: Question: Does preoperative neutrophil-to-lymphocyte ratio predict response to first-line platinum-based chemotherapy and prognosis in serous ovarian cancer?
Answer: Our findings indicated that high levels of preoperative NLR might be a potential biomarker of worse response to first-line platinum-based chemotherapy and poor clinical outcomes in patients with SOC. Further validation of this easily available parameter as a potential stratification tool in prospective studies should be encouraged.
