Clinical data were collected from medical records, including name, age, gender, preoperative-neutrophil, preoperative-lymphocyte, con-lymphocyte, con-platelet, post-neutrophil, post-lymphocyte, post-platelet, tumor size, tumor site, histopathological tumor grade, dose of gross tumor volume of tumor bed, dose of Clinical Tumor volume 1, dose of Clinical Tumor volume 2, WHO grade, adjuvant treatment methods (chemo-radiotherapy, radiotherapy, chemotherapy, or only surgical resection), and cycles of adjuvant chemotherapy. The endpoints included the OS, progression-free survival (PFS). The calculated methods were as follows: SII = platelets × neutrophils/lymphocytes, NLR = neutrophils/lymphocytes, and PLR = platelets/lymphocytes.
