Filter by:This study aims to explore the 2-year DFS (disease-free survival) rate and organ retention rate and to explore the ORR, PCR rate, 2y-OS， and quality of life of patients.
A phase II, single-arm, open-label study evaluating feasibility, safety and efficacy of combined chemotherapy and pembrolizumab as neoadjuvant/adjuvant therapy in stage IIa-IIIB NSCLC adult patients followed by adjuvant PD-(L)1 inhibitor treatment for up to 1 year
The aim of this study is to evaluate the safety and efficacy of fluzoparib combined with abiraterone in neoadjuvant treatment of patients with high-risk locoregional prostate cancer. Dr. Yao Zhu from Fudan University Shanghai Cancer Center is the co-leading PI of this study.
This trial is a single-center clinical trial to evaluate the tumor shrinkage and safety of tislelizumab combined with axitinib in Neoadjuvant therapy of T2-T3N0M0 renal clear cell carcinoma
This is a single-arm, prospective, non-randomized, single-center, open label clinical study for evaluating the efficacy and safety of neoadjuvant pyrotinib combined with epirubicin and cyclophosphamide followed by docetaxel in HR positive and HER2-low-expressing early or locally advanced breast cancer.
Neoadjuvant or primary systemic treatment is increasingly applied in the treatment of operable breast cancer. Down staging of the primary tumor is one of the important goals of neoadjuvant chemotherapy treatment (NCT), thereby permitting breast-conserving treatment without affecting the risk for a local relapse. Complete pathological response (pCR) rates after NCT vary across histological subtypes and can be more than 60% in HER2-positive disease with dual blockade therapy. Down staging of the axilla is also observed in patients initially presenting with metastatic lymph nodes. pCR rates in the axilla vary between 22% and 42% in reported series, again depending on tumor subtype. Omission of axillary lymph node dissection (ALND) can avoid the post-operative morbidity such as lymphedema in the short or long term follow-up. Metastatic lymph node status is hard to be stated as a pCR in the axilla by using physical examination or imaging such as ultrasonography or tomography after complete NCT. Good response to the axilla lymph node causing the difficulty of tissue proof by using core needle biopsy, though the investigator knew that biopsy stands for the definite tool for the confirmation of the residual disease. One proposed method to decrease the false-negative rate (FNR) is clip placement in the positive node at initial diagnosis with confirmation of clipped node resection at surgery. The correlation between the axillary lymph node identified on initial axillary ultrasound and the sentinel lymph nodes (SLNs) identified at surgery has not been fully evaluated. The concordance between percutaneous biopsy and the lymph node resected at the time of SLNB is not 100%. Sometimes, the initial node identified by ultrasound is not one of the SLNs. The impairment of the performance of SLNB might correlated to the alteration of lymphatic flow induced by tissue fibrosis or tumor deposits after NCT. The investigator hypothesized that the clip placement at diagnosis of node-positive disease with removal of the clipped node during SLNB reduces the FNR of SLNB after NCT. Here, we evaluate how often the lymph node containing the clip placed at percutaneous biopsy before chemotherapy was found at surgery to be one of the SLNs, and how often it was found in the nodes retrieved at ALND. In addition, the investigator report the impact of identification of the clipped node within the SLNs on the FNR of SLNB.
Neoadjuvant chemoradiotherapy is recommended as standard therapy for resectable esophageal cancer. The recurrence rate after surgery following neoadjuvant chemoradiotherapy is about 35%. Whether achieving pathological complete response after neoadjuvant chemoradiotherapy is significantly associated with recurrence after surgery. It is reported that immunotherapy combined with chemotherapy improved survival compared with chemotherapy alone in first line therapy of advanced esophageal cancer. We hypothesize that the addition of immunotherapy to neoadjuvant chemoradiotherapy is helpful to improving pathologic complete response and survival.
The investigators evaluate the response of rectal cancer to neoadjuvant therapy and classify the response according to specific periods of time after the end of neoadjuvant treatment.
China with high incidence of esophageal cancer, the number of new cases and deaths account for about 50% of the world every year. In the past few decades, surgery, radiotherapy, chemotherapy and other treatments were continuously improved, however, the mortality of esophageal squamous cell carcinoma patients was not significantly decreased. For patients with locally advanced esophageal cancer, direct surgery is not effective. It is difficult to achieve radical resection by surgery merely, and even if many patients receive surgery, they may eventually have tumor recurrence and poor survival rate. Therefore, it is necessary to explore effective perioperative neoadjuvant treatment to reduce the risk of postoperative recurrence and improve the postoperative survival rate of patients. According to the reports, the expression of PD-L1 in esophageal cancer was about 41.4%. Therefore, PD-1/ PD-L1 immunocheckpoint inhibitor may become a new method for the treatment of esophageal cancer. Preliminary clinical results showed that immunotherapy combined with chemoradiotherapy provided a synergies antitumor effect. Multiple clinical results showed that Carrillizumab provided higher overall response rate for advanced esophageal cancer. However, in patients with locally advanced esophageal cancer, the efficacy of Carrillizumab combined with chemotherapy and apatinib for sequential radical surgery is still unclear. The purpose of this study is to observe and evaluate the efficacy and safety of Carrillizumab combined with chemotherapy and antiangiogenic drugs in the neoadjuvant therapy of resectable esophageal squamous cell carcinoma.
