Background: VEGF is an important factor for angiogenesis. Although many previous studies have reported an increased serum VEGF concentration in various malignant tumors, there are few studies on the relationship between serum VEGF concentration and its prognosis. This study investigated whether serum VEGF concentration is a prognostic indicator for lung cancer.
Methods: Using the ELISA kit, we measured the serum VEGF concentrations of 86 patients diagnosed with lung cancer on histologic examination. With a cut off value of 686 pg/mL, the patients were classified as low-concentration (< 686 pg/mL, n=58) or high-concentration (> or = 686 pg/mL, n=28) based on their mean serum VEGF concentration values to compare survival rates, and serum VEGF concentrations for different histologic types and stages.
Results: There was no significant difference in serum VEGF concentration based on stage and histologic type between the two groups. Moreover, there was no significant difference in survival rate between the high-concentration and low-concentration groups (p=0.86).
Conclusion: This study demonstrates that serum VEGF concentration is not associated with the prognosis of lung cancer.

Background: Hepatocellular carcinoma (HCC) is characterized by high postoperative recurrence rates, and predicting early recurrence is crucial for improving clinical outcomes, yet remains challenging. Both preoperative computed tomography (CT) imaging radiomic features and serum biomarkers related to microvascular infiltration are important indicators of HCC prognosis. This study aimed to develop a nomogram model incorporating both preoperative CT radiomic features and serum biomarkers associated with microvascular infiltration to predict early postoperative recurrence in HCC patients.

The contemporary concept of carcinogenesis summarizes the role of hypoxia, neoangiogenesis, and hemostasis, including in the stage of progression and metastasis of the tumor process. Metastatic disease is a serious therapeutic challenge for any oncological condition. The purpose of this study was to evaluate the dynamics of specific indicators of neoangiogenesis and hypoxia as potential biomarkers for therapeutic efficacy or risk of disease progression in patients with brain metastases (BM) undergoing robotic stereotactic radiosurgery.
