Progression-free Survival

This is an open-label, single-arm, multi-center Phase II clinical trial evaluating the efficacy and safety of a novel sequential regimen as first-line therapy for treatment-naïve patients with Extranodal NK/T-cell Lymphoma (ENKTL). The study consists of a Screening Phase, a Safety Lead-in Phase, and a Treatment Phase. During the Safety Lead-in Phase, 6 patients will be enrolled to receive a fixed dose of Sintilimab and Chidamide combined with Azacitidine to verify the dose (testing 100mg/d on days 1-3 versus days 1-5). Following the lead-in, all subjects will undergo a 2-cycle Immunotherapy Induction Phase with the SCA regimen (Sintilimab, Chidamide, and Azacitidine). Subsequently, treatment will be stratified based on response: patients achieving Complete Response (CR) or Partial Response (PR) will receive 4 additional cycles of SCA consolidation, while those with Stable Disease (SD) or Progressive Disease (PD) will switch to 4 cycles of P-GemOx chemotherapy. Upon completion of systemic therapy, all patients will undergo consolidative involved-field radiotherapy (≥50Gy).

This is a single site, non-randomized, open-label, long-term safety and efficacy follow-up study for Phase 1 studies that evaluate the safety and efficacy of CAR T cells: NCT05660369 (DF/HCC# 22-175) and NCT06026319 (DF/HCC# 23-474).

To investigate progression-free survival (PFS) in patients with metastatic colorectal cancer treated with chemotherapy FOLFIRI monotherapy or chemotherapy FOLFIRI combined with Metformin

This study aims to assess the impact of adding olanzapine to nutritional advice and standard anti-tumor therapy on the survival and safety of patients with locally advanced, unresectable or metastatic gastric cancer, esophageal cancer, hepato-pancreaticobiliary cancer, and lung cancer. Researchers seek to determine whether olanzapine can improve progression-free survival (PFS), overall survival (OS), and objective response rate (ORR) in advanced cancer patients who received standard anti-tumor therapy, and investigate the relationship between olanzapine-induced weight changes and patient survival.

The main question it aims to answer are: 1. whether the new target delineation scheme can improve Progression-free Survival 2. whether it can reduce the incidence of radiation complications in high-grade glioma patients. Participants in trial group will be performed radiotherapy of new target delineation method after the completion of the operation within 4-6 weeks., while participants in the control group be performed radiotherapy of EORTC(European organisation for research and treatment of cancer) target delineation method.Temozolomide 75 mg / ( m² · d ) will be given to both groups of patients during radiotherapy. After radiotherapy, its dose changes to 150 \~ 200 mg / ( m² · d ) for 5 days and stopped for 23 days as a cycle. There are 6 cycles in total.

The R0 resection rate of gastrointestinal stromal tumor (GIST) with high recurrence risk was relatively low, and the relapse-free survival rate was relatively low, which needed to be further improved. A few retrospective analyses and a small sample of prospective studies have found that neoadjuvant therapy with imatinib mesylate can improve R0 resection rates. Whether neoadjuvant therapy prolongs long-term survival remains unclear. The primary objective of this study was to evaluate 5-year progression-free survival (PFS) for GIST patients with high recurrence risk after neoadjuvant treatment with imatinib mesylate.

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.
