Filter by:This study is a single-arm, open, single-center clinical study to observe and evaluate the efficacy and safety of sovalteinib in combination with solutumab and tegeo in second-line and post-line treatment of patients with advanced pancreatic cancer. A total of 30 patients were enrolled in this study, which was divided into 3 phases: screening phase, treatment phase and follow-up phase. During the treatment period, tumor status was evaluated by imaging methods every 6 weeks (±7 days) until disease progression (PD, RECIST 1.1) or death (during patient treatment) or intolerable toxicity, and tumor treatment and survival status after disease progression were recorded. Safety observations included AE, changes in laboratory test values, vital signs, and changes in ECG. In addition, 10 ml of blood was drawn for testing in our laboratory before each treatment and at the time of disease progression before the patients were enrolled, and the exploration of the efficacy-related biomarker BRCA1 was performed by blood samples.
Postoperative adjuvant radiotherapy is a key component of comprehensive treatment of meningioma. However, for atypical meningioma after total resection, there is still a huge controversy in patients who need adjuvant radiotherapy after surgery. Many scholars have focused on this problem and carried out some small-scale retrospective studies, but they have contradictory results. Some of the studies found that postoperative adjuvant radiotherapy could not improve the prognosis of patients, but was questioned because the sample size was too small, resulting in insignificant results, while other studies found that postoperative adjuvant radiotherapy can improve progression free survival. A study based on the National Cancer Database found that postoperative adjuvant radiotherapy and gross tumor resection are associated with a good prognosis. A recent meta-analysis enrolled a total of 757 patients and found that postoperative adjuvant radiotherapy reduced the risk of tumor recurrence but did not improve survival time. Our team reviewed the meningioma data in the SEER database and conducted a study previously. The study found that postoperative adjuvant radiotherapy did not improve the overall survival of these patients. The relevant research results were recently published in Frontiers in oncology. We further reviewed and summarized the single-center data of our hospital and found that postoperative adjuvant radiotherapy could not improve the progression free survival and overall survival of patients. Besides, we also performed a meta-analysis and found that postoperative adjuvant radiotherapy had a trend to improve progression-free survival, but there was no statistical difference. Because there are many deficiencies in previous researches, and the research results are also contradictory, it is still unclear whether patients with atypical meningioma who have undergone gross total resection can benefit from postoperative adjuvant radiotherapy. Further high quality clinical trials is still needed to be conducted in order to guide the postoperative care of patients. Therefore, we intend to conduct this multicenter randomized controlled trial to determine the value of postoperative adjuvant radiotherapy in patients with atypical meningioma who underwent gross total resection.
