The negative and weak positive rate of CD31 expression in the experimental group was higher than the control group, whereas the generally positive and strong positive rate of CD31 expression was significantly lower than the control group in the early stage (P less then 0.05). Conclusion ADC values may change at the early stage before the morphological changes of tumors. Changes in cell density and necrosis ratio of transplanted tumors correspond to the changes in ADC values. DWI can be used for the early prediction of esophageal cancer radiotherapy efficacy.Context Osteosarcoma (OS) is a progressive primary bone tumor that originates from immature stromal spindle cells. After chemotherapy, the serum-related indexes which are related to the prognosis. Aims The aim of this study is to investigate the correlation between changes in serum cyclooxygenase-2 (COX-2), basic fibroblast growth factor (bFGF), vascular endothelial growth factor (VEGF), transforming growth factor-beta (TGF-β), and tumor-specific growth factor (TSGF) levels and prognosis of patients with osteosarcoma (OS) before and after treatment. Settings and design Data of 75 patients with OS (observation group) and 55 healthy controls (control group) were retrospectively analyzed. Materials and methods Chemotherapy was administered to the observation group. Serum lactate dehydrogenase, alkaline phosphatase, and TSGF levels were measured before and after treatment. The observation group patients were classified as normal or abnormal according to the changes in serum COX-2, bFGF, VEGF, TGF-β, and TSGF levels of these biomarkers after chemotherapy was high.Hepatocellular carcinoma (HCC) is one of the most common malignant tumors.
