Research on Nutritional Risk Indexes and Inflammatory Indicators in Postoperative Complications and Prognosis of Epithelial Ovarian Cancer Patients

Influence of Nutritional Risk Indexes and Inflammatory Indicators on Postoperative Complications and Prognosis of Epithelial Ovarian Cancer and Construction of Prediction Models

The goal of this observational study is to explore the influence and predictive significance of nutritional risk indicators and inflammatory indicators on postoperative complications and prognosis of patients with epithelial ovarian cancer (EOC). The main question it aims to answer is:

Can preoperative nutritional risk and inflammatory indexes predict postoperative complications? Do preoperative nutritional risk and inflammatory indexes better predict the prognosis of patients with epithelial ovarian cancer? Which index is the best predictor of postoperative complications or prognosis for patients?

Inclusion Criteria:

1. histologically confirmed primary epithelial ovarian, peritoneal, and fallopian tube cancers.
2. patients received comprehensive staged surgery or debulking surgery.
3. available data of laboratory examination within 7 days before the surgery.

Exclusion Criteria:

1. borderline ovarian tumor.
2. receipt of neoadjuvant chemotherapy.
3. presence of other conditions influencing laboratory data, like hepatitis, kidney disease, autoimmune diseases, infectious diseases, blood disease, etc.
4. concurrent cancer in other organs.
5. absence of surgery or biopsy only.
6. multiple staged surgeries.
