NCT07528066
The goal of this observational study is to learn whether tumor and nodal downstaging after neoadjuvant chemo-immunotherapy is associated with better surgical outcomes in patients with clinical stage IIB-III non-small cell lung cancer (NSCLC) undergoing robotic-assisted thoracic surgery. The main question it aims to answer is: Is downstaging after neoadjuvant chemo-immunotherapy associated with better surgical outcomes in patients with stage IIB-III NSCLC undergoing robotic-assisted surgery? Participants with resectable or potentially resectable stage IIB-III NSCLC who receive neoadjuvant chemo-immunotherapy as part of their routine clinical care and then undergo curative-intent robotic-assisted surgery will be prospectively enrolled from international centers. Clinical, operative, pathological, and postoperative outcome data will be collected, including R0 resection, the extent of resection, conversion to open surgery, postoperative complications, length of stay, readmission, and mortality.
NCT07478900
Study Description This prospective cohort study evaluates the feasibility and effectiveness of pre-neoadjuvant tumor localization using skin tattooing, with or without radiopaque clips, in patients with biopsy-proven T2-T3 breast cancer and axillary lymph node metastasis. Eligible patients will undergo tumor localization in the supine position with the ipsilateral arm abducted to 90°. Palpable tumor margins will be marked with sterile tattoo ink, and deep or mobile tumors will receive additional localization with ultrasonography-guided radiopaque clips. Following localization, patients will receive standard neoadjuvant chemotherapy. Tumor response will be monitored clinically and radiologically. Post-therapy, the tattoo markings and/or clips will guide breast-conserving surgery. Primary outcomes include feasibility of breast conservation, achievement of negative margins (R0 resection), and avoidance of mastectomy, while intraoperative technical challenges will also be documented.
NCT07127497
This study is designed as a single-center, phase II exploratory clinical trial to evaluate the pathological response rate and safety of sintilimab (PD-1 inhibitor) combined with XELOX regimen (oxaliplatin + capecitabine) for neoadjuvant treatment of LARC. The study focuses on the pMMR/MSS patient population and attempts to provide a new treatment option for patients who cannot tolerate radiotherapy or need to preserve organ function.
NCT07137858
Neoadjuvant immunochemotherapy can effectively increase the postoperative pathological complete response rate, improve the survival rate of patients, and reduce the risk of recurrence in oral squamous cell carcinoma (OSCC). Programmed death ligand-1 (PD-L1) plays a role in inhibiting the cancer-immune cycle by binding to negative regulatory factors of T cell activation such as PD-1 and B7.1. It has achieved good therapeutic effects in lung cancer, liver cancer and other cancers. Previous studies have shown that three cycles of PD-L1 inhibitors combined with chemotherapy have satisfactory efficacy and safety in locally advanced oral squamous cell carcinoma. However, during the three-cycle treatment process, due to the accumulation of drug toxicity, patients' tolerance to adverse reactions decreases, increasing the risk of serious adverse events and psychological pressure on patients. Based on this, this study aims to explore the efficacy of two cycles of avelumab (PD-L1 inhibitor) combined with chemotherapy in locally advanced oral squamous cell carcinoma, to explore whether it can achieve the same efficacy as three cycles while shortening the treatment time, reduce the risk of serious adverse events, and further verify the efficacy and safety of PD-L1 inhibitors combined with chemotherapy in the treatment of locally advanced oral squamous cell carcinoma. This study uses the postoperative pathological complete response (PCR) rate as the primary outcome indicator, and the objective response rate (ORR), major pathological response (MPR) rate, 2-year disease-free survival (EFS) rate, and 2-year and 5-year overall survival (OS) rate as secondary outcome indicators to evaluate the efficacy and long-term survival impact.
NCT06289062
This multicenter, prospective clinical trial is designed to enroll PD-L1 expression-positive patients with stage IB1 cervical cancer who desire fertility preservation to undergo neoadjuvant chemotherapy in combination with a PD-1 inhibitor to evaluate the rate of complete pathologic remission, treatment-related adverse events, pregnancy rate, miscarriage rate, preterm birth rate, live birth rate, EFS and OS.
NCT06288373
It is a prospective, open-label, randomized, controlled phase II/III clinical trial in which patients with PD-L1-positive FIGO stage IB3, IIA2 and IIB(tumors \>4 cm in diameter)will be enrolled and randomly divided into the neoadjuvant chemoimmunotherapy plus surgery group and the CCRT group.
NCT06056336
The purpose of this study is to analyze esophageal cancer patients who underwent neoadjuvant immunotherapy with chemotherapy followed by esophagectomy to determine whether additional adjuvant therapy is associated with improved survival outcomes.
